PROJECT INCLUDES THE EXTENSION OF STANFORD DRIVE, WHICH WILL CONNECT TO AN EXTENSION OF CUESTA DRIVE. AN INITIAL STUDY/MITIGATED NEGATIVE DECLARATION IS PROPOSED FOR ADOPTION (CEQA). PROJECT ADDRESS: 468/500 Westmont Ave. BY: Kyle Van Leeuwen, Associate Planner Phone Number: (805) 781-7091 E-mail: kvanleeuwen@slocity.org FILE NUMBER: SBDV-0169-2020, FROM: Tyler Corey, Deputy Director EID-0170-2020 RECOMMENDATION Adopt a resolution (Attachment A) recommending the City Council approve Tentative Tract Map (TTM) No. 3157 and adopt the associated Initial Study/Mitigated Negative Declaration. SITE DATA SUMMARY The applicant has submitted a Tentative Tract Map (TTM) application to subdivide the subject parcel into 23 residential lots. No residential development is proposed at this time; however, recordation of the map would require the installation of public impr ovements, including new roads, water, wastewater, and stormwater infrastructure (Attachment B, Vesting Tentative Tract Map & Phasing Plan). This project was reviewed by Planning Commission on May 26, 2021. The commission moved to continue the item to allow for Applicant Andrew G. Meinhold, Alice Jo Meinhold Survivors Trust Representative Katie Rollins, Cannon Zoning Low-Density Residential (R- 1) General Plan Low Density Residential Site Area 4.98 acres Environmental Status Initial Study-Mitigated Negative Declaration (IS/MND) Meeting Date: 7/28/2021 Item Number: 4a Time Estimate: 90 Minutes Page 9 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 2 completion of the 30-day public comment period on the environmental document prepared for the project and to allow for staff to incorporate additional information and clarifications that address public comments regarding California red-legged frog, burrowing owl, and other concerns about biological impacts. The commission also directed staff to work with the applicant to review alternative grading concepts to further preserve large trees, and to address concerns raised related to transportation and traffic impacts (Attachment C, Planning Commission Staff Report and Meeting Minutes). At the hearing on May 26th, many neighbors stated that they did not receive a mailed notice about the Planning Commission hearing. Since that hearing, staff discovered that the notices intended to be sent for the May 26th hearing did not go out with the appropriate batch and were received late. Due to the circumstances, review of this item is considered a de novo hearing and will be presented as such with additional atte ntion to those areas highlighted at the previous hearing. This will also allow for those commissioners not present at the May 26th hearing to participate. 1.0 COMMISSION’S PURVIEW Review the project for consistency with the General Plan, Subdivision Regulati ons and applicable City development standards and guidelines. Planning Commission (PC) review is required for projects that include the subdivision of five or more lots (Subdivision Regulations, Table 1). The PC’s role is to make a recommendation to the City Council on the proposed subdivision and associated environmental document (Attachment D, Initial Study/Mitigated Negative Declaration). This project is subject to the Department of Housing and Urban Development’s Housing Accountability Act. 1 2.0 PROJECT STATISTICS AND SETTING The project proposes 23 residential lots on a 4.98-acre site zoned for residential use (R- 1). The proposed lots are consistent with the Subdivision Regulations standards for lot size and dimensions and the proposed streets and other improvements are consistent with current engineering standards. No exceptions to the subdivision regulations have been proposed. The project site has a creek that crosses the western portion of the site. Lots have been proposed in an arrangement that allows for creek setbacks to be applied to those lots adjacent to the creek and allow for an adequate buildable area outside those applied setbacks. 1 A tentative tract map application to subdivide lots for residential use is a “housing development project” under the HAA, and is therefore, afforded the protections set forth in California Government Code Section 65589.5(j)(1). (See Honchariw v. County of Stanislaus (2011) 200 Cal. App. 4th 1066, 1074.)

The 4.98-acre site is located at the terminus of the east and west portions of Westmont Avenue and the northern terminus of Cuesta Drive and Stanford Drive. Existi ng development on the project site includes two residential structures and associated accessory structures, a pool, and other site improvements. Vegetation on the property Page 11 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 4 includes a freshwater forested/shrub wetland with associated riparian habitat that e xtends through the western portion of the site. The site is generally comprised of developed/ruderal land, riparian habitat, and annual grassland. There are 177 ornamental and native trees throughout the project site. Surrounding land and Zoning are as follows: West: Single-family residences zoned Low-Density Residential (R-1). North: Cal Fire San Luis Obispo Unit Headquarters (Fire Station #12), outside city limits. East: Single- and multi-family residences zoned Low-Density (R-1) and Medium-Density (R-2). South: Single-family residences zoned Low-Density Residential (R-1). 3.0 PREVIOUS REVIEW The project was previously reviewed by the Planning Commission (PC) on May 26, 2021; however, as noted above, review of this item is considered a de novo hearing. At the May 26th hearing, the PC received presentations and testimony from staff, the applicant’s team, and the public, and provided direction and comments to staff and the applicant. The result of this hearing was a motion to continue the item to allow for the completion of the 30-day public comment period on the environmental document, and to allow for staff to incorporate additional information and clarifications that address public comments regarding wildlife and biological resources, to explore alternative grading concepts that would allow for greater protection of large trees, and to address concerns raised related to transportation impacts (discussed below). The project was reviewed by the City’s Tree Committee on May 17, 2021, for consistency with the Tree Regulations. The Tree Committee (TC) recommended that, with the inclusion of the recommended condition of approval for compensatory planting, the PC find the proposed tree removals consistent with the City’s Tree Regulations (Attachment E, Tree Committee Staff Report and Draft Minutes). The TC recommended that the project approval include a condition to provide compensatory tree plantings at a one -to- one ratio on site, consistent with Municipal Code requirements, and that compensatory plantings consist of an even mix of 15-gallon and 24-inch tree box sizes. The recommendation also stipulated that 50% of the required compensatory plantings be of a native species. This condition has been included in the proposed resolution as Condition #5. The TC also included in their motion a request that the Planning Commission consider the retention of several specific trees onsite. This included one eucalyptus within the creek corridor (#114), and two eucalyptus and one live oak near the southern edge of the property line on proposed lots 23 (#s 33, 34, & 91). 4.0 PROJECT ANALYSIS The project must conform to the standards and limitations of the Subdivision Regulations and be consistent with the General Plan. Staff has evaluated the project and the PC shall consider if the project is in substantial compliance with the applicable policies and standards, as discussed in this analysis. The project aligns with the Major City Goal to address Housing and Homelessness, as the project would facilitate the production of housing; 23 lots for single-family residential development created from one existing residential lot. Page 12 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 5 4.1 Consistency with the General Plan The General Plan Land Use Element (LUE), Circulation Element (CE), and Housing Element (HE) provide policies for the conservation and development of residential neighborhoods. The Conservation and Open Space Element (COSE ) also provides policies to preserve and protect natural resources on the project site. The project is consistent with these policies in several aspects. LUE Policy 2.2.3 Neighborhood Traffic: Neighborhoods should be protected from intrusive traffic. All neighborhood street and circulation improvements should favor pedestrians, bicyclists, and local traffic. Vehicle traffic on residential streets should be slow. To foster suitable traffic speed, street design should include measures such as narrow lanes, landscaped parkways, traffic circles, textured crosswalks, and, if necessary, stop signs, speed humps, bollards, and on -street parking and sidewalks. LUE Policy 2.2.4 Neighborhood Connections: The City shall provide all areas with a pattern of streets, pedestrian network, and bicycle facilities that promote neighborhood and community cohesiveness. There should be continuous sidewalks or paths of adequate width, connecting neighborhoods with each other and with public and commercial services and public open space to provide continuous pedestrian paths throughout the city. Connectivity to nearby community facilities (such as parks and schools), open space, and supporting commercial areas shall also be enhanced, but shall not be done in a method that would increase cut-through traffic. CE Policy 4.1.4 New Development: The City shall require that new development provide bikeways, secure bicycle storage, parking facilities and showers consistent with City plans and development standards. When evaluating transportation impacts, the City shall use a Multimodal Level of Service analysis. CE Policy 5.1.3 New Development: New development shall provide sidewalks and pedestrian paths consistent with City policies, plans, programs, and standards. When evaluating transportation impact, the City shall use a Multimodal Level of Service analysis. HE Policy 7.3: New residential developments should incorporate pedestrian and bicycle linkages that provide direct, convenient and safe access to adjacent neighborhoods, schools, parks, and shopping areas. The design of the subdivision protects the existing neighborhood from intrusive traffic by only connecting the two existing streets to the south, avoiding any increase in cut-through traffic between other existing neighborhoods and Highway 1. The subdivision design also incorporates a potential bicycle and pedestrian connection to the east, as well as parkways, on-street parking, and sidewalks. Page 13 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 6 Figure 1: Subdivision Design Circulation Connections LUE Policy 2.3.5. Neighborhood Pattern: The City shall require that all new residential development be integrated with existing neighborhoods. Where physical features make this impossible, the new development should create new neighborhoods. The design of the subdivision integrates with the existing neighborhood by continuing the street layout of Stanford and Cuesta Drive, including street width, sidewalks, and parkways (see Figure 2 as example). Figure 2: Cuesta Drive Street Design Connection to Existing LUE Policy 2.3.7. Natural Features: The City shall require residential developments to preserve and incorporate as amenities natural site features, such as landforms, views, creeks, wetlands, wildlife habitats, wildlife corridors, and plants. Page 14 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 7 LUE Policy 2.3.10 Site Constraints: The City shall require new residential developments to respect site constraints such as property size and shape, ground slope, access, creeks and wetlands, wildlife habitats, wildlife corridors, native vegetation, and significant trees. COSE Policy 7.7.9 Creek Setback B.: Development approvals should respect the separation from creek banks and protection of floodways and natural features identified in part A above (buildings, streets, driveways, etc.), whether or not the setback line has been established. The TTM identifies the dimensions of the creek and existing riparian area. The lots proposed adjacent to the creek are a larger size so that creek protection measures, such as compliance with the applied creek setback requirements, can be met and still allow development of the created parcel. The TTM also proposes no development or grading activities in the southwest corner of the site, where the creek and associated vegetati on is most prominent and established. In all, over 60 coast live oaks, will be retained within the protected creek corridor area, as well as other native species . Figure 3: Creek Corridor, trees number in black within setbacks are retained 4.2 Consistency with Subdivision Regulations Lots Size and Dimensions The Subdivision Regulations regulates minimum lot sizes in the R-1 zone and sets specific development standards. The minimum lot size allowed in the R-1 zone is 6,000 square feet with a minimum width of 50 feet and a minimum depth of 90 feet. Lots are also required to have a minimum street frontage of 20 feet. All the lots within the proposed Page 15 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 8 subdivision meet these base requirements for size and dimension. Additionally, the Subdivision Regulations states that any area between creek banks shall be excluded from the calculation of minimum lot area. The TTM has also demonstrated compliance with this requirement (See Table 1 above). The Subdivision Regulations also call for natural contours of the site to be preserved to the greatest extent possible in new subdivisions and for lot lines to be generally perpendicular to the street (§16.18). The design of the subdivision is consistent with these standards. Corner Lots Lot 19 of the TTM is the only “corner lot” included in the proposed subdivision. Per Table 3 of the Subdivision Regulations, corner lots in residential subdivisions shall have a minimum area of 15% greater than otherwise required and shall be ten feet wider that otherwise required. Lot 19 does provide a width of no less than 60 feet, consistent with this standard, but is less than 15% larger than the minimum lot area. Staff has included in the proposed resolution condition #3 which requires the area of lot 19 to be increased to no less than 6,900 square feet for final map recordation, consistent with regulations standards for corner lots. This can be achieved by moving the lot line between Lot 19 and lot 20 approximately 2 feet, without compromising Lot 20’s compliance with minimum lot size or dimension standards. Only minor changes in site grading will be needed with this adjustment of lot lines. 5.0 ANALYSIS OF PC DIRECTIONAL ITEMS The following analysis section concentrates on the specific areas identified by the PC at the May 26th hearing. 5.1 Environmental Review Prior to the May 26th hearing public comment was received regarding the biological analysis incorporated into the Initial Study. Areas of concern were specific to the adequate protection of the riparian and wildlife corridor, the California red -legged frog, and the burrowing owl. In response to these comments, the applicant’s biologist and City’s Sustainability and Natural Resource Officer re-visited the site on June 10th to further evaluate the conditions of the site and adjacent creek areas, and the applicant’s biologist, Kevin Merk, has provided a memorandum in response to those comments (Attachment F). The conclusions of that analysis and additional staff analysis are provided below. The Initial Study/Mitigated Negative Declaration has been updated in certain areas as needed in connection to the information below in respo nse to public comments and Planning Commission direction. These modifications do not require recirculation of the IS/MND because the edits constitute minor modifications and clarifications to an adequate MND and do not include significant new information that would result in a new significant environmental impact or a substantial increase in the severity of a significant environmental impact. Within the Initial Study document all new text is indicated by underlined, bold, and italicized text. Deleted text is indicated by strike-through (Attachment D). Additional information and discussion about certain areas of the Environmental Review are provided in Attachment C. Page 16 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 9 Riparian Corridor and Creek Protection The project proposes to remove nonnative species from the riparian corridor and this removal is recommended by the project's Fire Protection Plan (Attachment K) to reduce fuel loads; this does not include the redwood trees in the corridor. The effects of these actions and other measures within the creek corridor are described in the Biological Resource Analysis and further discussed in the Memorandum, provided by Kevin Merk. The conclusion of that analysis is that with the application of creek setbacks, establishment of an open space easement, and the habitat enhancements proposed (such as the removal on non-native species and replanting of native species), the habitat value of this creek area will increase, and the wildlife corridor connecting areas to the north and south will be maintained and enhanced. Additional Information on Creek Protection The section of Twin Ridge Creek located on the project site is not a creek subject to creek setback requirements outlined in the General Plan and Zoning Regulations. While the project plans identify a 20-foot setback from the riparian area, these 20-foot setbacks do not reflect a current requirement for the site. The creek setback standards in the Zoning Regulations (Section 17.70.030 (B)), state: creek setback requirements shall apply to all creeks as defined in the General Plan Open Space Element and shown on that element’s creek map, and only to those creeks. This section of Twin Ridge Creek is not identified on the Conservation and Open Space Element2 (COSE) Creek Map and therefore, is not currently subject to creek setback requirements. The creek setbacks were shown on plans at the recommendation of staff and are intended to show that a usable building envelope is provided on each lot adjacent to th e creek, in anticipation that the application of creek setbacks would likely be included as a mitigation measure or tract condition. This also demonstrates that the lots were specifically designed by the applicant to include appropriate creek protection, e ven if the Zoning Regulations do not specifically require a 20-foot setback for the onsite creek. Creek protection is also consistent with guidelines found in the Subdivision Regulations.3 The IS/MND includes mitigation measure BIO-11, which requires the application of creek setback standards to the sites adjacent to the creek. This means that creek setback requirements will be applied to the newly created lots adjacent to the creek when structures are proposed, even though this section of Twin Ridge Creek is not identified on the COSE creeks map. Extent of Riparian Edge During the recent review of the riparian corridor and associated analysis documents, a discrepancy was identified in the method used to determine the extent of the creek’s riparian area, and the extent of jurisdictional areas. The applicant’s initial delineation of the creek’s riparian area did not include areas covered by non -native trees such as the eucalyptus and acacia trees, and the delineation has been adjusted to include this additional area in Attachment G (Review of Preservation of Trees & Alternative Grading Concept). This revised delineation is consistent with the City’s Creek Setback standards, 2 City of San Luis Obispo, Conservation and Open Space Element: Figure 9: Creeks and Wetlands: https://www.slocity.org/home/showpublisheddocument/4110/635497639403930000 3 Subdivision Regulations, §16.18.155 (1): Creeks and their corridors are to be preserved as open space, and creek corridors are to be maintained in essentially a natural state to protect the community’s water quality, wildlife diversity, and aesthetic value. Page 17 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 10 which state that creek setbacks shall be measured from the existing top of bank or from the edge of the predominant pattern of riparian vegetation, whichever is further from the creek flow line (Section 17.70.030.C). While the City’s creek setback requirements do not apply to this specific creek, as noted above, the language in the Zoning Re gulations explaining how the setback would be measured is a useful tool to use when determining the extent of riparian area that should be protected. In response to this discrepancy, and the direction from PC to explore the possibility of retaining more trees on site (discussed further below), the applicant has provided an additional exhibit showing the revised delineation in addition to an alternative grading approach and new locations for storm water treatment/retention. These new grading and retention locations would be outside this expanded riparian area and would allow for the retention of the non-native species; however, as discussed further below, retaining these non-native trees would conflict with the Fire Protection Measures that are recommended to mitigate a potential wildfire impact. This change in delineation of the riparian corridor to include non-native species does not result in a new significant impact or increase the severity of an identified impact because the physical effects of the proj ect on the environment, including and not limited to proposed tree removals, was adequately addressed in the Initial Study, and the clarifications that have been incorporated into the Initial Study include evidence in support of the impact determinations. Mitigation requiring compensatory plantings would be required. California Red Legged Frog In the Biological Resource Assessment provided by Kevin Merk, it was stated that California red-legged frog (CRLF) was “unlikely” to occur on the project site based on lack of suitable habitat and separation from known breeding sites to the north. Public comments received by the City suggested that a “permanently wetted” branch of Twin Ridge Creek downstream of the site may provide suitable habitat for CRLF. Upon furt her review by Merk (Attachment F), the areas identified by the commenter are not suitable for CRLF breeding due to the small size of pools and insufficient water depth and lack of vegetation cover. Furthermore, while this creek is within a 116,517-acre area designated as critical habitat for the CRLF, Twin Ridge Creek has not been identified as red -legged frog habitat in the California Natural Diversity Database (Attachment H, Biological Resource Assessment). Any currently identified breeding sites are sepa rated from the project site by a major barrier (Highway 1), leading to the conclusion that there is a very low potential for CRLF to utilize the project site or adjacent wetted areas for breeding or dispersal. In addition, required mitigation includes pre-construction surveys and biological monitoring to ensure avoidance and protection of special-status species. Based on the analysis in the IS/MND and supplemental evaluation (Attachment F), no additional studies or mitigation measures are warranted. Burrowing Owl Burrowing owls are rare in the coastal San Luis Obispo area, and according to the California Department of Fish and Wildlife are believed to no longer nest in this region. The project site is highly manipulated from years of human occupation, and the onsit e grassland areas are used regularly for horses and are mowed and managed. This species is very sensitive to human activity and the proximity of the site to dense urban Page 18 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 11 development in the city further reduces the habitat value for this species, especially considering the extensive grasslands to the north along Highway 1 that are further away from human activities. No Burrowing Owls were observed during field investigations. The mitigation measures included with the IS/MND require a pre-construction survey and provide protections in the case that a Burrowing Owl is discovered on site or in close proximity. Based on this analysis no additional studies or mitigations are warranted . Hydrology and Water Quality Public comments received by the City stated that the project would result in substantial erosion and increased discharge into the creek, and that the project would substantially decrease groundwater recharge. While the project would increase the amount of impervious surface, the project will be required to comply with the drainage requirements of the City’s Waterways Management Plan. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. The Waterways Management Plan and Low Impact Development (LID) stormwater treatment requires that site development be designed so that post -development site drainage does not significantly exceed pre-development run-off. The proposed drainage measures would be implemented to catch additional surface runoff generated from the project during operation. As further described in the Drainage Report (Attachment I), the proposed approach to peak flow management for this project would result in an overall reduction in peak flow into Twin Ridge Creek. The propo sed approach to peak flow management includes collecting a portion of the runoff from the proposed development, detaining that flow in a detention facility, and then introducing it to Twin Ridge Creek. Other locations on site collect and detain runoff with in an underground detention facility and then released onto streets consistent with the current drainage condition for the site. The project is also required to comply with Post -Construction Stormwater Management Requirements, including requirements for site design, water quality treatment, runoff retention, and peak discharge management. These requirements include, and are not limited to, minimizing impervious surfaces, collecting stormwater runoff to reduce pollutant discharge, and maintaining the pre -developed hydrology by reducing overland flow and promoting groundwater recharge. Therefore, based on compliance with existing regulations and recommended mitigation measures, no significant hydrology and water quality impacts would occur. 5.2 Tree Preservation The Planning Commission directed staff and the project applicant to explore alternative grading approaches to further preserve large trees currently on site that are identified for removal (Attachment J, Tree Removal Exhibit). Staff discussed and evaluated with the applicant possible modifications to site grading, and this analysis also took into consideration how changes in proposed site grading would affect the project’s compliance with Subdivision Regulations, Engineering Standards and other City codes and standards. The overall conclusion of these evaluations was that greater tree protection in most instances would require such changes in grading or site engineering that the project would be brought out of compliance with applicable regulations an d standards related to Page 19 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 12 grading and site engineering. A summary of this evaluation and conflicts has been provided by the applicant (Attachment G, Review of Preservation of Trees & Alternative Grading Concept). In addition, retention of the non -native trees would conflict with the Fire Protection Report, which calls for non-native trees within the corridor to be removed. The Subdivision Regulations call for the natural contours of a site to be largely preserved, and storm water and drainage standards call for runoff to be retained and managed within the site. Compliance with these requirements paired with the fact that large trees are often located at low points of the site where water naturally collects, presents an unavoidable conflict with the preservation of trees. For other larger trees not located in low lying areas, engineering standards for street and driveway grades, and limits on retaining wall heights, constrain how much the subdivision design can be modified to facilitate tree preservation while maintaining compliance with those standards. While tree protection policies are applicable to the project, a proposed subdivision must first and foremost be compliant with the Subdivision Regulations and Engineering Standards. This project does not include any exceptions to subdivision standards or engineering standards for streets and driveways. Trees within the Creek Corridor The applicant has provided an additional exhibit showing how the project can be executed while retaining the non-native trees within and directly adjacent to the riparian area, with grading and stormwater treatment/retention areas moved outside of these ar eas. While retention of the non-native trees in this area is possible as shown on the applicant’s additional exhibit, staff notes that this would conflict with the Fire Protection Report, which calls for non-native trees within the corridor to be removed. The City’s Fire Marshall required a Fire Protection Report be provided for the project, and this report provides effective ways to mitigate fire risk. The Fire Protection Report’s recommendations are incorporated as mitigation measures for the project and would mitigate potential wildfire impacts to a less than significant level. In conjunction with the removal of non -native trees in the riparian area, mitigation measure BIO-10 requires a compensatory mitigation program to ensure no net-loss of riparian habitat. These replanting efforts will “fill in” some areas where non-native species were removed and will become the new riparian edge. When development of specific lots occurs, the setback will be measured from this edge. Staff recommends that the language of condition #4 be modified from the previous resolution as follows: Plans submitted for final map recordation shall include the Biological Easement required by mitigation measure BIO- 11. This easement shall include all the area between the creek top of bank, or current riparian area, or replanted areas which are planned directly adjacent to the creek, whichever is furthest from the centerline of the creek. The easement shall also cover all areas identified for Cambria morning glory replanting required by mitigation measure BIO-1. This will ensure that compensatory planting areas intended to compensate for removal of non-native species receive open space easement protections. Page 20 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 13 5.3 Transportation and Traffic Concerns Planning Commission directed staff to address concerns raised by neighboring residents related to traffic impacts of the project. The evaluation of the project includes analysis of Vehicle Miles Traveled (VMT), consistency with the Circulation Element, potential hazards due to a geometric design feature or incompatible uses, and emergency access. This analysis concludes that there are no significant impacts related to transportation and traffic. In evaluating the impacts of new streets and level of service, staff found that the existing streets would become safer than the current condition with the extension of Cuesta Drive connecting to an extension of Stanford Drive. While the extension of the two streets would increase the number of vehicles utilizing them, approximately seven additional homes using Stanford and nine using Cuesta, these new street connections would also improve emergency access. Currently, these two streets do not terminate in a cul-de-sac turnaround, which is an undesirable scenario. With the two streets connected, residents in the area will have a second means of evacuation, and emergency vehicle response is improved. For these reasons, staff does not recommend modifications to the project’s current street design. 6.0 OTHER DEPARTMENT COMMENTS The project has been reviewed by various City departments and divisions including Planning, Engineering, Utilities, Fire, Building, Office of Sustainability, Natural Resources, and the City Arborist.

PC-XXXX-21 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF SAN LUIS OBISPO, CALIFORNIA, RECOMMENDING THE CITY COUNCIL ADOPT A MITIGATED NEGATIVE DECLARATION OF ENVIRONMENTAL REVIEW AND TENTATIVE TRACT MAP NO. 3157 TO CREATE TWENTY-THREE (23) RESIDENTIAL LOTS IN THE LOW- DENSITY (R-1) ZONE (SBDV-0169-2020/EID-0170-2020) WHEREAS, the Tree Committee of the City of San Luis Obispo conducted a web based public hearing on May 17, 2021, recommending the Planning Commission find the project consistent with the Tree Regulations Ordinance, pursuant to a proceeding instituted under SBDV- 0169-2020, Alice Jo Meinhold Survivors Trust, applicant; and WHEREAS, the Planning Commission of the City of San Luis Obispo conducted a web based public hearing on May 26, 2021, continued the review of the project to a future date, pursuant to a proceeding instituted under SBDV-0169-2020, Alice Jo Meinhold Survivors Trust, applicant; and WHEREAS, the Planning Commission of the City of San Luis Obispo conducted a public hearing in the Council Chambers of City Hall, at 990 Palm Street, on July 28, 2021, pursuant to a proceeding instituted under SBDV-0169-2020, and EID-0170-2020, Alice Jo Meinhold Survivors Trust, applicant; and WHEREAS, notices of said public hearings were made at the time and in the manner required by law; and WHEREAS, the Planning Commission of the City of San Luis Obispo has duly considered all evidence, including the testimony of the applicant, interested parties, and evaluation and recommendations by staff, presented at said hearing. NOW, THEREFORE, BE IT RESOLVED by the Planning Commission of the City of San Luis Obispo as follows: SECTION 1. Findings. The Planning Commission hereby recommends the City Council approve the project (SBDV-0169-2020, & EID-0170-2020), based on the following findings: 1. As conditioned, the project will not be detrimental to the health, safety, and welfare of persons living or working at the site or in the vicinity because the project respects site constraints and will be compatible with the scale and character of surrounding neighborhoods. 2. The proposed subdivision, together with the provisions for its design and improvement, is consistent with the General Plan because: Page 23 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 2 a. The Land Use Element provides that the purpose of the Low-Density Residential land use designation is to provide for single family detached dwellings, which the subdivision is designed and intended to accommodate, and complies with the maximum density limit of seven density units per acre. b. The project is consistent with Land Use Element Policies 2.2.3 and 2.2.4, Circulation Element Policy 5.1.3, and Housing Element Policy 7.3 because the design of the subdivision protects the existing neighborhood from intrusive traffic by avoiding any increase in cut-through traffic between other existing neighborhoods and Highway 1 and by incorporating a potential bicycle and pedestrian connection to the east, as well as parkways, on-street parking, and sidewalks with proposed streets. c. The project is consistent with Land Use Element Policy 2.3.5 because the design of the subdivision integrates with the existing neighborhood by continuing the street layout of Stanford Drive and Cuesta Drive, including street width, sidewalks, and parkways. d. The project is consistent with Land Use Element Policy 4.2.1 because the project respects the separation from creek banks by identifying the dimensions of the creek and existing riparian area. The lots proposed adjacent to the creek are a larger size (24,451 to 7,884 square feet) so that creek protection measures, such as compliance with creek setback requirements, can be met and still allow residential development within the created parcels. The project also proposes no development or grading activities in the southwest corner of the site, where the creek and associated vegetation is most prominent and established. e. The project is consistent with Housing Element Policy 6.8 because the project will facilitate residential infill development. 3. The design of the subdivision provides, to the extent feasible, for future passive or natural heating or cooling opportunities in the subdivision because the project has demonstrated that development of the proposed lots can be achieved in compliance with the setback standards of the Zoning Regulations, which are intended to help provide air circulation and exposure to sunlight. 4. As conditioned, the subdivision and associated tree removals are consistent with the City’s Tree Regulations because the project will be required to provide compensatory tree plantings at a rate consistent with Municipal Code requirements with a size and species of tree found to be appropriate by the Tree Committee. 5. The design of the tentative map and proposed improvements are not likely to cause serious health problems or substantial environmental damage since further development or redevelopment of the proposed parcels will occur consistent with the City’s Development Standards, Engineering Standards, Mitigation Measures, and Conditions of Approval. Page 24 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 3 SECTION 2. Environmental Review. An Initial Study/Mitigated Negative Declaration (IS/MND) has been prepared in accordance with the California Environmental Quality Act (CEQA) to evaluate the potential environmental effects of the proposed project. The Planning Commission hereby recommends the City Council adopt the IS/MND and Mitigation, Monitoring, and Reporting Program, based on incorporation of the following mitigation measures, which will reduce potential environmental impacts to less than significant. The Initial Study/Mitigated Negative Declaration has been updated in certain areas as needed in response to public comments and Planning Commission direction. These modifications do not require recirculation of the IS/MND because the edits constitute minor modifications and clarifications to an adequate MND and do not include significant new information that would result in a new significant environmental impact or a substantial increase in the severity of a significant environmental impact. Air Quality AQ-1 Idling Control Techniques. During all construction activities and use of diesel vehicles, the applicant shall implement the following idling control techniques: 1. Idling Restrictions Near Sensitive Receptors for Both On - and Off-Road Equipment. a. Staging and queuing areas shall not be located within 1,000 feet of sensitive receptors if feasible; b. Diesel idling within 1,000 feet of sensitive receptors shall not be permitted; c. Use of alternative-fueled equipment shall be used whenever possible; and d. Signs that specify the no idling requirements shall be posted and enforced at the construction site. 2. California Diesel Idling Regulations. On-road diesel vehicles shall comply with 13 CCR 2485. This regulation limits idling from diesel-fueled commercial motor vehicles with gross vehicular weight ratings of more than 10,000 pounds and licensed for operation on highways. It applies to California- and non- California-based vehicles. In general, the regulation specifies that drivers of said vehicles: a. Shall not idle the vehicle’s primary diesel engine for greater than 5 minutes at any location, except as noted in Subsection (d) of the regulation; and b. Shall not operate a diesel-fueled auxiliary power system (APS) to power a heater, air conditioner, or any ancillary equipment on that vehicle during sleeping or resting in a sleeper berth for greater than 5 minutes at any location when within 1,000 feet of a restricted area, except as noted in Subsection (d) of the regulation. Signs must be posted in the designated queuing areas and job sites to remind drivers of the 5-minute idling limit. The specific requirements and exceptions in the regulation Page 25 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 4 can be reviewed at the following website: www.arb.ca.gov/msprog/truck- idling/2485.pdf. AQ-2 Particulate Matter Control Measures. During all construction and ground-disturbing activities, the applicant shall implement the following particulate matter control measures and detail each measure on the project grading and building plans: 1. Reduce the amount of disturbed area where possible. 2. Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site and from exceeding the SLOAPCD’s limit of 20% opacity for greater than 3 minutes in any 60-minute period. Increased watering frequency would be required whenever wind speeds exceed 15 miles per hour (mph). Reclaimed (non-potable) water should be used whenever possible. 3. All dirt stockpile areas (if any) shall be sprayed daily and covered with tarps or other dust barriers as needed. 4. Permanent dust control measures identified in the approved project revegetation and landscape plans shall be implemented as soon as possible, following completion of any soil-disturbing activities. 5. Exposed grounds that are planned to be reworked at dates greater than 1 month after initial grading shall be sown with a fast germinating, non-invasive, grass seed and watered until vegetation is established. 6. All disturbed soil areas not subject to revegetation shall be stabilized using approved chemical soil binders, jute netting, or other methods approved in advance by the SLOAPCD. 7. All roadways, driveways, sidewalks, etc. to be paved shall be completed as soon as possible. In addition, building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. 8. Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved surface at the construction site. 9. All trucks hauling dirt, sand, soil, or other loose materials are to be covered or shall maintain at least 2 feet of freeboard (minimum vertical distance between top of load and top of trailer) in accordance with California Vehicle Code (CVC) Section 23114. 10. “Track out” is defined as sand or soil that adheres to and/or agglomerates on the exterior surfaces of motor vehicles and/or equipment (including tires) that may then fall onto any highway or street as described in CVC Section 23113 and California Water Code (CWC) Section 13304. To prevent track out, designate access points and require all employees, subcontractors, and others to use them. Install and operate a “track-out prevention device” where vehicles enter and exit unpaved roads onto paved streets. The track-out prevention device can be any device or combination of devices that are effective at preventing track out, located at the point of intersection of an unpaved area and Page 26 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 5 a paved road. Rumble strips or steel plate devices need periodic cleaning to be effective. If paved roadways accumulate tracked-out soils, the track-out prevention device may need to be modified. 11. Sweep streets at the end of each day if visible soil material is carried onto adjacent paved roads. Water sweepers shall be used with reclaimed water where feasible. Roads shall be pre-wetted prior to sweeping when feasible. 12. All PM10 mitigation measures required should be shown on grading and building plans. 13. The contractor or builder shall designate a person or persons whose responsibility is to ensure any fugitive dust emissions do not result in a nuisance and to enhance the implementation of the mitigation measures as necessary to minimize dust complaints and reduce visible emissions below the SLOAPCD’s limit of 20% opacity for greater than 3 minutes in any 60 -minute period. Their duties shall include holidays and weekend periods when work may not be in progress (for example, wind-blown dust could be generated on an open dirt lot). The name and telephone number of such persons shall be provided to the SLOAPCD Compliance Division prior to the start of any grading, earthwork, or demolition (Contact Tim Fuhs at 805-781-5912). AQ-3 Geologic Evaluation. Prior to initiation of ground-disturbing activities, the applicant shall retain a registered geologist to conduct a geologic evaluation of the property, including sampling and testing for NOA in full compliance with SLOAPCD requirements and the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105). This geologic evaluation shall be submitted to the City Community Development Department upon completion. If the geologic evaluation determines that the project would not have the potential to disturb NOA, the applicant must file an Asbestos ATCM exemption request with the SLOAPCD. AQ-4 Naturally Occurring Asbestos Control Measures. If NOA are determined to be present onsite, proposed earthwork, demolition, and construction activities shall be conducted in full compliance with the various regulatory jurisdictions regarding NOA, including the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105) and requirements stipulated in the National Emission Standard for Hazardous Air Pollutants (NESHAP; 40 Code of Federal Regulations [CFR] Section 61, Subpart M – Asbestos). These requirements include, but are not limited to, the following: 1. Written notification, within at least 10 business days of activities commencing, to the SLOAPCD; 2. Preparation of an asbestos survey conducted by a Certified Asbestos Consultant; and 3. Implementation of applicable removal and disposal protocol and requirements for identified NOA. Page 27 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 6 AQ-5 Asbestos-Containing Material. Prior to issuance of demolition permits, the applicant shall provide an asbestos report that was prepared by a certified asbestos consultant. If ACM are determined to be present, at least 10 working days prior to any demolition work the applicant shall provide notification to SLOAPCD of such work. The notification shall include an asbestos report that was prepared by a certified asbestos consultant. ACM removal and disposal shall follow the requirements of the National Emission Standards for Hazardous Air Pollutants Regulation (NESHAP) Subpart M and of the SLOAPCD. Monitoring Program: These measures shall be incorporated onto Final Map and project grading/building plans for review and approval by the City Community Development Department. Compliance shall be verified by the City during regular inspections, in coordination with the SLOAPCD, as necessary. Biological Resources BIO-1 Implement a Rare Plant Mitigation Program that ensures no net loss of Cambria morning glory on the project site. Prior to any tract improvements, a Rare Plant Mitigation Program shall be implemented for Cambria morning glory and shall be overseen by a qualified botanist approved by the City. As a component of the program, seed shall be collected from Cambria morning glory plants during the appropriate season prior to tract grading activities. Using standard procedures, the qualified botanist shall clean and store the seeds until the receiving sites shown on the project plans are ready. Suitable habitat of 2,180 square-feet in size outside of the development area (as designated on the site plans in the creek setback zone) shall be designated as the mitigation site that will be maintained in a natural state and not be subject to mowing earlier than June 1 each year. The areas will be maintained as grassland habitat and no planting of ornamental species or other adverse modifications (such as grazing activities) will be allowed. The mitigation site shown on the project plans is twice the size as the areas currently occupied by the rare plant occurrences (2,180 square-feet of habitat created for 1,076 square-feet of habitat impacted). This equates to a 2:1 mitigation ratio (habitat created to habitat impacted) to ensure a minimum 1:1 replacement ratio is achieved. Topsoil from each of the four occurrences will be collected in 6 -inch lifts and stored for top-dressing the mitigation site once grading of the pads is complete. As needed, the mitigation site should be prepared for planting by removal of non-native species or other measures as necessary, then applying the salvaged topsoil. Once topsoil has been layered evenly through the area, collected seed should be hand-broadcasted into suitable locations by the qualified botanist and covered with compost. Seed may also be incorporated into the native erosion control seed mix described in the Native Erosion Control Seed Mix table under Mitigation Measure BIO-9 and applied to other grassy areas of the site as part of the erosion control effort. Depending on the season when construction starts, the qualified botanist may also potentially salvage plants (i.e., dig them up when soils are moist) and transplant them to containers to be maintained until the mitigation sites are ready for planting. Page 28 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 7 BIO-2 Conduct annual monitoring and implement adaptive management measures for 5 years to ensure no net loss of Cambria morning glory onsite. The Rare Plant Mitigation Program shall include annual monitoring and maintenance of the mitigation site to ensure success of the program. Monitoring by a qualified botanist shall occur during the spring growing season (between April 15 and May 15 each year) to ensure successful establishment of planted propagules. The established rare plants shall be mapped to evaluate the goal of no net loss of the species onsite. The measurable objective shall be to have at least 1,076 sf of occurrence comprised of approximately 300 Cambria morning glory plants. Appropriate vegetation sampling techniques shall be used to assess the areal cover of vegetation to evaluate the status of the established occurrences. If the success criteria of having approximately 300 plants covering 1,076 sf within the creek setback zone is not reached by the third year of monitoring, remedial actions such as collecting more seed and distributing it in suitable areas should be employed, with a corresponding additional year of monitoring. Other activities to increase the success of the rare plant mitigation effort could include non-native plant species removal within the mitigation site to reduce competition, additional seed application, or supplemental irrigation during periods of prolonged drought. The qualified botanist shall prepare annual reports for the applicant detailing the methods and results of the mitigation effort and monitoring effort. The applicant shall be responsible for submitting the report to the City on an annual basis (by December 31 of each year) for the 5-year monitoring period or until the final success criteria described above are met. BIO-3 To the extent feasible, avoid initial site grading in the winter months. The burrowing owl has been recorded in the vicinity of the project from October to the end of April. If initial vegetation removal and site grading for the tract improvements is conducted outside of this period, potential effects on this species would be avoided and no further mitigation would be required. Restricting the time period for earth-moving activities is also required to avoid or minimize the potential for erosion and sedimentation (see Mitigation Measure BIO-9). If initial grading work must commence during the time period that burrowing owls may be present onsite, preconstruction surveys for this species shall be included in the survey effort described in Mitigation Measure BIO -4 prior to vegetation removal or tract improvements. BIO-4 Conduct a preconstruction survey and avoid construction in areas occupied by special-status wildlife species until relocated or they have left the site. Within 7 days prior to the start of vegetation/tree removal, ground-disturbing activities, or demolition of existing structures, a biologist approved by the City shall survey the project impact area to identify whether nesting birds, roosting bats, monarch butterfly overwintering populations, obscure bumble bee, and/or California legless lizard are present on site. A separate survey shall be conducted for any phase of the project not conducted concurrently or within 10 days of cessation of the previous phase (i.e., structure demolition conducted prior to general site grading). The biologist shall use appropriate survey techniques for the special-status species identified in the 2020 BRA as having potential to occur onsite. For example, burrows shall be examined with binoculars or wildlife cameras, and inspected for whitewash or prey remains. Leaf litter and cover Page 29 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 8 objects shall be searched for northern California legless lizards. Potential bat roost sites shall be inspected for sign of roosting bats such as guano or prey remains. If any of these species are found onsite, the biologist shall coordinate with the City, and CDFW as appropriate, on methods to ensure the successful relocation of individuals to suitable habitat nearby. In some cases, CDFW may recommend creating structures for displaced woodrats and bats. Burrowing owls can be discouraged from using burrows onsite, or occupied burrows can be avoided until the owls have left the area. Bats can be restricted from roost sites by placing netting over their entrances after they have left the roost for night-time foraging. The wildlife protection measures to be employed will be based on the results of the survey and the particular characteristics of their use of the site, in coordination with CDFW and the construction engineer. If no special-status animal species are found onsite during the preconstruction survey, work may proceed with the implementation of the following Mitigation Measures BIO-5 through BIO-7. BIO-5 Prepare and present a Worker Environmental Awareness Program. Prior to any vegetation removal or tract improvements, a qualified biologist shall prepare a Worker Environmental Awareness Program that will be presented to all project personnel. This program shall detail measures to avoid and minimize impacts on biological resources. It shall include a description of special-status species potentially occurring on the project site and their natural history, the status of the species and their protection under environmental laws and regulations, and the penalties for take. Recommendations shall be given as to actions to avoid take should a special-status species be found on the project site. Other aspects of the training shall include a description of general measures to protect wildlife, including: 1. Delineation of the allowable work area, staging areas, access points, and limits to vehicle access; 2. Storage of all pipes, metal tubing, or similar materials stored or stacked on the project site for one or more overnight periods shall be either securely capped before storage or thoroughly inspected for wildlife before the materials are moved, buried, capped, or otherwise used. 3. Inspection of materials stored onsite, such as lumber, plywood, and rolls of silt fence, for wildlife that may have sheltered under or within the materials; 4. Use of netting to exclude birds from nesting in construction materials; 5. Construction of escape ramps in all excavations and trenches more than 6 inches deep; 6. Contact information for the City-approved biologist and instructions should any wildlife species be detected in the work site; 7. Dust suppression methods during construction activities when necessary, to meet air quality standards and protect biological resources; and 8. Methods for containment of food-related trash items (e.g., wrappers, cans, bottles, food scraps), small construction debris (e.g., nails, bits of metal and plastic), and other human generated debris (e.g., cigarette butts) in animal-proof containers and removal from the site on a weekly basis. Page 30 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 9 All project personnel who have attended the training shall sign an attendance sheet. The program shall be repeated for any new crews that arrive subsequently on the site. BIO-6 Install high-visibility construction and silt fence along the creek corridor to delineate the allowable work area, exclude wildlife from the site, and protect the stream habitat. Prior to vegetation removal or tract improvements, and during subsequent residential development for Lots 1-7, a high-visibility construction fence at least 4 feet tall together with a silt fence, or an approved wildlife exclusion fence, shall be erected along the creek corridor to delineate the limits of grading and vehicle access. If possible, the fence shall be erected along the creek setback line, and encroachment into the setback shall be kept at a minimum. In no case shall ground disturbance occur within the riparian habitat or below the top of bank without obtaining proper permits from regulatory agencies. The type of fence used may be a combination of wildlife exclusion and silt fence (i.e., ERTEC Triple-function E-fence) or similar materials that would serve the purposes of safety/construction area delineation, wildlife exclusion, and siltation prevention. The fence shall be checked weekly by construction personnel for needed maintenance. BIO-7 Conduct biological monitoring for special-status wildlife species while the property is cleared and graded, and structures are removed. A qualified biologist shall monitor the removal of structures, materials, and vegetation that may provide cover for obscure bumble bee, northern California legless lizards, and bat roosting sites. The biologist shall be onsite daily until all materials are removed and all vegetation has been cleared. If any special-status species are found, work shall be delayed until the individuals have left the work area or CDFW shall be notified to obtain authorization for capture and relocation. BIO-8 Avoid vegetation removal within the riparian habitat during the overwintering season. Vegetation removal within the riparian area shall be conducted outside of the overwintering season for monarch butterfly (late October through February) and obscure bumble bee (late October through January) to avoid disturbance to species potentially inhabiting riparian vegetation. BIO-9 Install erosion and sediment BMPs and revegetate graded areas. The following erosion and sedimentation control BMPs are required to be implemented during vegetation removal, tract improvements, during individual lot construction, and after the construction phases of the project: 1. If possible, the potential for erosion and sedimentation shall be minimized by scheduling construction to occur outside of the rainy season, which is typically defined as October 15 through April 15. Adherence to this measure would also serve as avoidance for the burrowing owl, as described in Mitigation Measure BIO-3. 2. To minimize site disturbance, all construction related equipment shall be restricted to established roads, construction areas, and other designated staging areas. The creek setback zone shall be clearly marked as described in Mitigation Measure BIO-6. Page 31 of 1225 Resolution No. PC-xxxx-21 468/500 Westmont Avenue, SBDV-0169-2020 & EID-0170-2020 Page 10 3. Prior to any site disturbance during tract improvements or individual lot construction, a Sediment and Erosion Control Plan shall be prepared by a qualified engineer. The use of silt fence, straw wattles, erosion control blankets, straw bales, sandbags, fiber rolls, and other appropriate techniques should be employed to protect the drainage features on and off the property.

Future development would incorporate the following fire reduction methods identified by the 2020 Wildland Fire Protection Report (Neumann)to reduce wildland fire risk: 1. Rain gutters, when not adequately maintained, will collect leaf material which becomes a receptive fuel bed for embers and sparks and can then transmit fire underneath the non-combustible roof materials. Rain gutters should be protected by noncombustible leaf shields or not allowed. 2. Record on all lots a deed restriction that allows for only non-combustible fences and decks in the subdivision. 3. Record on all lots a deed restriction that allows for fire resistant landscaping in the back yards of the subdivision. 4. Require enclosed eves on all structures within the subdivision. 5. Install fireproof vents on all structures (fire-rated, flame and ember resistant). 6. Working with the biologist, remove the non-native vegetation in the creek, riparian area, 7. reduce the fuel load. 8. Install a non-combustible wall (block or steel stud /stucco) wall 36 inches in height all around the northern perimeter of the subdivision. The wall shall begin at the westernmost property line and continue to the 20-foot setback at the west side of the creek and shall continue beginning at the 20-foot setback at the east side of the creek, terminating at the property line of CAL FIRE Station #12. The purpose of this wall is to interrupt fire progression from the north onto the proposed lots without obstructing the very desirable view of the open space. Monitoring Program: This measure shall be incorporated into Final Map and noted on all grading and construction plans. The City Community Development Department shall verify compliance through initial and regular inspections. SECTION 3. Action.

The 4.98- acre site is located at the terminus of the east and west portions of Westmont Avenue and the northern terminus of Cuesta Drive and Stanford Drive. Existing development on the project site includes a residential structure and associated accessory structures, a pool, and other site improvements. Vegetation on the property includes a freshwater forested/shrub wetland with associated riparian habitat that extends through the western portion of the site. The site is generally comprised of developed/ruderal land, riparian habitat, and annual grassland. There are 177 ornamental and native trees throughout the project site. Surrounding land and Zoning are as follows: West: Single-family residences zoned Low-Density Residential (R-1). North: Cal Fire San Luis Obispo Unit Headquarters (Fire Station #12), outside city limits. East: Single- and multi-family residences zoned Low-Density (R-1) and Medium-Density (R-2). South: Single-family residences zoned Low-Density Residential (R-1). Item 2 Packet Page 4Page 56 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 3 3.0 PREVIOUS REVIEW The project was reviewed by the City’s Tree Committee on May 17, 2021 for consistency with the Tree Regulations. The Tree Committee (TC) recommended that, with the inclusion of the recommended condition of approval for compensatory planting, the PC find the proposed tree removals consistent with the City’s Tree Regulations (Attachment 3, Tree Committee Staff Report and Draft Minutes). The TC recommended that the project approval include a condition to provide compensatory tree plantings at a one-to-one ratio on site, consistent with Municipal Code requirements, and that compensatory plantings consist of an even mix of 15-gallon and 24-inch tree box sizes. The recommendation also stipulated that 50% of the required compensatory plantings be of a native species. This condition has been included in the proposed resolution as Condition #5. The TC also included in their motion a request that the Planning Commission consider the retention of several specific trees onsite. This included one eucalyptus within the creek corridor (#114), and two eucalyptus and one live oak near the southern edge of the property line on proposed lots 23 (#s 33, 34, & 91). Staff does not recommend retention of these trees as retention of the eucalyptus in the creek corridor is inconstant with wildfire mitigation measure W-1, and retention of trees near the southern property line would require a redesign of the stormwater treatment/retention system and changes in lot grading. 4.0 PROJECT ANALYSIS The project must conform to the standards and limitations of the Subdivision Regulations and be consistent with the General Plan. Staff has evaluated the project and the PC shall consider if the project is in substantial compliance with the applicable standards, as discussed in this analysis. 4.1 Consistency with the General Plan The General Plan Land Use Element (LUE), Circulation Element (CE), and Housing Element (HE) provide policies for the conservation and development of residential neighborhoods. The Conservation and Open Space Element (COSE) also provides policies to preserve and protect natural resources on the project site. The project is consistent with these policies in several aspects. LUE Policy 2.2.3 Neighborhood Traffic: Neighborhoods should be protected from intrusive traffic. All neighborhood street and circulation improvements should favor pedestrians, bicyclists, and local traffic. Vehicle traffic on residential streets should be slow. To foster suitable traffic speed, street design should include measures such as narrow lanes, landscaped parkways, traffic circles, textured crosswalks, and, if necessary, stop signs, speed humps, bollards, and on-street parking and sidewalks. LUE Policy 2.2.4 Neighborhood Connections: The City shall provide all areas with a pattern of streets, pedestrian network, and bicycle facilities that promote neighborhood and community cohesiveness. There should be continuous sidewalks or paths of adequate width, connecting neighborhoods with each other and with public and commercial services and public open space to provide continuous pedestrian paths throughout the city. Connectivity to nearby community facilities (such as parks and schools), open space, and supporting commercial areas shall also be enhanced, but shall not be done in a method that would increase cut-through traffic. Item 2 Packet Page 5Page 57 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 4 CE Policy 4.1.4 New Development: The City shall require that new development provide bikeways, secure bicycle storage, parking facilities and showers consistent with City plans and development standards. When evaluating transportation impacts, the City shall use a Multimodal Level of Service analysis. CE Policy 5.1.3 New Development: New development shall provide sidewalks and pedestrian paths consistent with City policies, plans, programs, and standards. When evaluating transportation impact, the City shall use a Multimodal Level of Service analysis. HE Policy 7.3: New residential developments should incorporate pedestrian and bicycle linkages that provide direct, convenient and safe access to adjacent neighborhoods, schools, parks, and shopping areas. The design of the subdivision protects the existing neighborhood from intrusive traffic by only connecting the two existing streets to the south, avoiding any increase in cut-through traffic between other existing neighborhoods and Highway 1. The subdivision design also incorporates a potential bicycle and pedestrian connection to the east, as well as parkways, on-street parking, and sidewalks. Figure 1: Subdivision Design Circulation Connections LUE Policy 2.3.5. Neighborhood Pattern: The City shall require that all new residential development be integrated with existing neighborhoods. Where physical features make this impossible, the new development should create new neighborhoods. The design of the subdivision integrates with the existing neighborhood by continuing the street layout of Stanford and Cuesta Drive, including street width, sidewalks, and parkways (see Figure 2 as example). Item 2 Packet Page 6Page 58 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 5 Figure 2: Cuesta Drive Street Design Connection to Existing LUE Policy 2.3.7. Natural Features: The City shall require residential developments to preserve and incorporate as amenities natural site features, such as land forms, views, creeks, wetlands, wildlife habitats, wildlife corridors, and plants. LUE Policy 2.3.10 Site Constraints: The City shall require new residential developments to respect site constraints such as property size and shape, ground slope, access, creeks and wetlands, wildlife habitats, wildlife corridors, native vegetation, and significant trees. COSE Policy 7.7.9 Creek Setback B.: Development approvals should respect the separation from creek banks and protection of floodways and natural features identified in part A above buildings, streets, driveways, etc.), whether or not the setback line has been established. The TTM identifies the dimensions of the creek and existing riparian area. The lots proposed adjacent to the creek are a larger size so that creek protection measures, such as compliance with creek setback requirements, can be met and still allow development of the created parcel. The TTM also proposes no development or grading activities in the southwest corner of the site, where the creek and associated vegetation is most prominent and established. In all, over 60 coast live oaks, will be retained within the protected creek corridor area, as well as other native species.

The minimum lot size allowed in the R-1 zone is 6,000 square feet with a minimum width of 50 feet and a minimum depth of 90 feet. Lots are also required to have a minimum street frontage of 20 feet. All of the lots within the proposed subdivision meet these base requirements for size and dimension. Additionally, the Subdivision Regulations states that any area between creek banks shall be excluded from the calculation of minimum lot area. The TTM has also demonstrated compliance with this requirement (See Table 1 above). Corner Lots Lot 19 of the TTM is the only “corner lot” included in the proposed subdivision. Per Table 3 of the Subdivision Regulations, corner lots in residential subdivisions shall have a minimum area of 15% greater than otherwise required and shall be ten feet wider that otherwise required. Lot 19 does provide a width of no less than 60 feet, consistent with this standard, but is less than 15% larger than the minimum lot area. Staff has included in the proposed resolution condition #3 which requires the area of lot 19 to be increased to no less than 6,900 square feet for final map recordation, consistent with regulations standards for corner lots. This can be achieved by moving the lot line between Lot 19 and lot 20 approximately 2 feet, without compromising Lot 20’s compliance with minimum lot size or dimension standards. Only minor changes in site grading will be needed with this adjustment of lot lines. Item 2 Packet Page 8Page 60 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 7 5.0 ENVIRONMENTAL REVIEW The proposed project has been analyzed pursuant to the California Environmental Quality Act CEQA). An Initial Study-Mitigated Negative Declaration (IS/MND) was prepared and is currently being circulated. The IS/MND was noticed for circulation on April 29, 2021 and will be circulated until May 29, 2021 for public review. The Planning Commission shall review the environmental analysis (refer to Attachment 4 Initial Study/Mitigated Negative Declaration) and provide a recommendation to the City Council regarding adoption of the IS/MND. The following discussion highlights some of the more significant topics of the environmental analysis. Biology The initial study and associated biological survey identified Cambria morning glory within the annual grassland on site, which is a special-status plant species. Construction of the project would result in the removal or disturbance of the Cambria morning glory. Implementation of Mitigation Measures BIO-1 and BIO-2 reduce potential impacts to Cambria morning glory to less than significant. These measures require implementation of a Rare Plan Mitigation Program that would establish replanting of Cambria morning glory so that after a 5-year period there would be no net loss of the plant on site. The project site contains a riparian forest along the onsite creek located in the western portion the property. The identified riparian forest consists of native riparian trees and shrubs, and native understory plants are also present within the riparian area. In addition, the Fire Protection Plan requires removal of non-native trees within the riparian habitat, resulting in the removal of 13 trees, primarily acacia (silver wattle) trees. The proposed TTM shows the extent of the riparian area and a 20-foot creek setback, which would be further protected by implementation of mitigation measure BIO-11, which requires recordation of a biological easement on the Final Map and application of creek setback standards. No paving or structures would be permitted in the biological easement area, however, grading activity is proposed in several areas within the creek setback for stabilization, and placement of rip rap pads are proposed within or adjacent to the setback1. The project requires permits described in Mitigation Measure BIO-10 for work proposed within the riparian area. The easement and application of creek setback standards would affect proposed Lots 1–8. Wildfire The project area and adjacent lands are identified as low and moderate wildland fire risk in the Safety Element of the General Plan. The Element states that development shall only be approved when adequate fire suppression services and facilities are available or will be made concurrent with development. Parcel upgrades include emergency access, upgraded roads, and necessary utility connections. To manage wildfire risk associated with placing residents in close proximity to moderate and high fire hazard severity areas, a Vegetation/Fuel Management Plan for the project site has been identified in Mitigation Measure WF-1. Additionally, a Wildland Fire Protection Report identifies mitigation measures to further reduce wildland fire hazards to future development and is described in Mitigation Measure WF-2. Part of this mitigation measure calls for the removal of non-native plant species within the creek corridor to manage wildfire risk. 1 Zoning Regulations § 17.70.030 G. Exceptions to Creek Setback: 2. Accessory Structures and Uses. The following items may be located within the required creek setback without obtaining a discretionary exception unless otherwise noted, provided, that they do not extend beyond the top of bank into the creek channel; will not cause the removal of native riparian vegetation; will not reduce any flooding capacity in compliance with the City’s flood damage prevention regulations; in total occupy not more than one -half of the total required creek setback area; and are consistent with other property development standards of the Zoning Regulations. h. Natural flood control and stormwater improvements, including vegetated buffers, bioswales, and rain gardens. Item 2 Packet Page 9Page 61 of 1225 SBDV-0169-2020 & EID-0170-2020 468/500 Westmont Page 8 5.1 Comments Received Comments were received from the State Department of Toxic Substances Control recommending certain broad-based evaluations be included in the MND Hazards and Hazardous Materials section. In review of these recommendations, staff finds that the Initial Study sufficiently identifies the potential impacts related to hazardous materials for this project and project site. Given the project’s size, location, and surroundings, potential impacts would be mitigated by Mitigation Measures AQ- 3, AQ-4 and AQ-5. This was the only comment received at the time of publication of this report. The applicant has agreed to all mitigation measures proposed specific to this project. The IS/MND shall constitute the complete environmental determination for the project. 5.0 OTHER DEPARTMENT COMMENTS The project has been reviewed by various City departments and divisions including; Planning, Engineering, Utilities, Fire, Building, Office of Sustainability, Natural Resources and the City Arborist. Comments have been incorporated into the draft resolution as conditions of approval. 6.0 ACTION ALTERNATIVES 6.1 Continue the item. An action to continue the item should include a detailed list of additional information or analysis required. 6.2 Deny the project. An action denying the application should include findings that cite the basis for denial and should reference inconsistency with the General Plan, Subdivision Regulations, Zoning Regulations or other policy documents. 7.0 ATTACHMENTS 1.

Zoning: R-1 (Low Density Residential) 8. Description of the Project: The 468-500 Westmont Drive Tentative Tract Map Project (project) is a request to the City of San Luis Obispo (City) for a Tentative Tract Map (TR 3157) for the subdivision of one existing parcel (Assessor’s Parcel Number [APN] 052-496-001) totaling 4.98 acres into 23 individual parcels meant to facilitate residential development on land in the R-1 (Low Density Residential) zone. The new parcels would range in size from 6,000 to 22,78324,451 square feet (sf) and would be located at 468 and 500 Westmont Drive, at the northern edge of the city limits (Figure 1). Access improvements would include a proposed 54- to 60-foot-wide access road beginning at the existing Page 67 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 2 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 terminus of Stanford Drive and looping east to connect with the existing terminus of Cuesta Drive. The variation in the road width accounts for existing widths of Cuesta and Stanford Drives. This access road would provide access to Lots 4–16 and 19–23. Lots 1–3 would take access from a shared driveway off the western terminus of Westmont Avenue and Lots 17 and18 would be accessed from the eastern terminus of Westmont Avenue. Parking for the tract would be provided onsite, and each residential lot is designed to accommodate the required two parking spaces for each lot. The development proposes a connection to the existing waterline on Stanford Drive and looping it around to Cuesta Drive. An additional water line from Westmont Avenue would connect to Cuesta Drive through an easement across Lot 15. A 17-foot-wide, asphalt-concrete (AC) easement across Lot 15 from Westmont Avenue to Cuesta Drive is proposed for drainage, utility, and bicycle/pedestrians. A drainage basin is also proposed within the easement. A design exception for the easement (bicycle pathway) is requested as the current slope is 9 percent, which exceeds the standard of 8 percent. A proposed 15-foot-wide sewer line easement is proposed along the western property line of Lot 10. There is an existing sewer line that extends across Lot 10 that would be relocated within the proposed easement. A fire lane easement is proposed across Lots 1–3 that would be used for emergency vehicle access and would contain a sewer line that serves Lots 1-3. A 10-foot-wide public utility easement is proposed along the frontages of Lots 4–16 and 19–23. A 10-foot-wide Pacific Gas and Electric Company (PG&E) easement is proposed along the rear yards of Lots 3 and 7–18 and an additional PG&E easement is proposed along the western edge of Lots 1–3. Drainage easements are proposed along Lots 4, 15, and 19–23 and would be designed to comply with the City’s Low Impact Development (LID) requirements. Proposed drainage measures include an 85th percentile retention area, a 95th percentile retention area, and Filterra and Biofiltration treatment. Four-foot retaining walls located in the rear or side yards would be provided for slope stability on Lots 1-5 and 8-23. Additional 3-foot retaining walls would be provided on Lots 8 and 9 for wildland protection. (See Attachment 2.) The project includes a phasing plan that would allow for the final map recordation into three phases, as allowed under Section 66456.1 of the Government Code. Phase one would include Lot 1, Lot 2, Lot 3, Lot 17, and Lot 18. Phase two would include Lots 4 through 10 and Lots 21 through 23. Phase three would include Lot 11 through 16, Lot 19, and Lot 20.

The project site is generally surrounded by one- and two-story residential units to the south, east and west. There is undeveloped residential land to the north of the project site and California Department of Forestry and Fire Protection (CAL FIRE) Station #12 located directly northeast. There is a freshwater forested/shrub wetland with an associated riparian habitat that extends through the western portion of the project area that would be located at the rear (eastern) end of Lots 1–3 and the rear (western) end of Lots 4–8. The freshwater forested/shrub wetland connects to a freshwater emergent wetland located on undeveloped land to the north of the project site. The site is generally comprised of developed/ruderal land, riparian habitat, and annual grassland. There are 177 ornamental and native trees throughout the project site, a rock outcropping between Lots 1 and 2, and presence of Cambria morning glory (Calystegia subacaulis ssp. episcopalis; a rare plant species) on Lots 3–6. Page 70 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 5 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The project would demolish two existing residential structures and several accessory structures to accommodate the tract improvements. To accommodate the onsite improvements, 86 ornamental and native trees would be removed. Acacia trees located in riparian areas would be removed; however, the project proposes to replace Acacia trees with native vegetation, including toyon (Heteromelis arbutifolia) or oaks. Proposed improvements would result in 4.27 acres of groundwork, which includes 7,900 cubic yards (cy) of cut and 4,760 cy of fill. No residential development on the new parcels is proposed at this time, but it is anticipated that each new parcel will be developed as a single-family residential use, for a total of 23 single-family residential units. Each single- family residential property has the potential to include an accessory dwelling unit (ADU) and a junior accessory dwelling unit (JADU), as an accessory use to the single-family residential use. 9. Project Entitlements: Development Review Tree Removal Permit 10. Surrounding Land Uses and Settings: Surrounding uses and stories of surrounding buildings are summarized below: • North: undeveloped residential land and CAL FIRE Station #12 • East: one- and two-story single-family residences; apartments beyond • South: one- and two-story single-family residences • West: one- and two-story single-family residences 11. Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code Section 21080.3.1? If so, is there a plan for consultation that includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? Native American tribes were notified about the project consistent with City and State of California (State) regulations including, but not limited to, Assembly Bill (AB) 52. A representative from the Salinan tribe requested a cultural resource specialist from their tribe be onsite to monitor all ground disturbing activities, and this measure has been included as a mitigation requirement (see Section 18, Tribal Cultural Resources). 12.

A brief explanation is required for all answers except “No Impact” answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone). A “No Impact” answer should be explained where it is based on project-specific factors as well as general standards (e.g. the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2. All answers must take account of the whole action involved, including off -site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact' is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4. “Negative Declaration: Less Than Significant with Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section 19, "Earlier Analysis," as described in (5) below, may be cross- referenced). 5. Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration (Section 15063 (c) (3) (D)). In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures Incorporated,” describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they addressed site-specific conditions for the project. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g. general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7. Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8. The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance Page 77 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 12 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 1. AESTHETICS Except as provided in Public Resources Code Section 21099, would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Have a substantial adverse effect on a scenic vista? 1, 4 ☐ ☐ ☒ ☐ b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, open space, and historic buildings within a local or state scenic highway? 1, 4, 5, 6 ☐ ☐ ☒ ☐ c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? 1, 4, 7 ☐ ☐ ☒ ☐ d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? 1, 7 ☐ ☐ ☒ ☐ Evaluation The City of San Luis Obispo General Plan Conservation and Open Space Element (COSE) identifies specific goals and policies intended to protect and enhance the city’s visual quality and character. Policies in the COSE include, but are not limited to, promoting the creation of “streetscapes” and linear scenic parkways during construction or modification of major roadways, designing new development to be consistent with the surrounding architectural context, and preserving natural and agricultural landscapes. The COSE and City of San Luis Obispo General Plan Circulation Element assign scenic value ratings of “moderate” and “high” to several roadways in the city, based on the availability of views of scenic resources from these public viewpoints. According to the Circulation Element, the segment of U.S. Route 101 (US 101) through the city of San Luis Obispo is identified as having moderate and high scenic value. The COSE also identifies Santa Rosa Street, as having moderate to high scenic value; however, neither Westmont Avenue, Stanford Drive, or Cuesta Drive have any scenic designation. The COSE does not identify any “cones of view” or other important scenic vistas in the project site vicinity. The project is located on land that is zoned R-1 (Low Density Residential) near the northern city limit. The surrounding land uses include one- and two-story residences to the south, east, and west, undeveloped land to the north, and CAL FIRE Station #12 to the northeast. Bishop Peak is prominent to the northwest. The existing parcel supports two existing residential units and a common carport that is accessed by a private Driveway off Stanford Drive. Ruderal vegetation is present onsite surrounding the existing development. The project site includes a freshwater forested/shrub wetland with associated riparian habitat in the western portion of the project site. The project site also includes a rock outcropping and presence of Cambria morning glory, a rare plant species, in the western portion of the project site. The remainder of the site is primarily comprised of annual grassland and ornamental and native trees. While no specific development proposal has been identified for the site, based on the underlying zoning and proposed parcel sizes, this analysis assumes that future development would consist of residential development. Such development would be subject to development standards identified in Chapter 17.16 Low-Density Residential (R-1) Development Standards and the City’s Community Design Guidelines, which are intended to provide for infill projects of high architectural quality that are compatible with existing development. A scenic vista is generally defined as a high-quality view displaying good aesthetic and compositional values that can be seen from public viewpoints. A substantial adverse effect on a scenic vista would occur if the proposed project would significantly degrade the scenic landscape as viewed from public roads or other public areas. Some scenic vistas are officially or informally designated by public agencies or other organizations. Based on the COSE map of scenic roadways and vistas, the project site is not directly located along roadways considered to be of moderate or high scenic value or within the cone of view of a scenic roadway. Santa Rosa Street is the nearest road of scenic value, located Page 78 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 13 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 approximately 415 feet east of the project site. Existing development including an apartment complex located at the corner of Westmont Avenue and Santa Rosa Street as well as other residential units would block views of the project from Santa Rosa Street. Residential development is not currently proposed; however, future development would be consistent with existing residential units and would comply with City design and zoning standards; therefore, the project would not affect adversely affect a scenic vista and potential impacts would be less than significant. The section of US 101 that extends through the city of San Luis Obispo is classified as an eligible State Scenic Highway but is not officially designated by the California Department of Transportation (Caltrans). Santa Rosa Street eventually turns into State Route (SR) 1 north of the project site, which extends along California’s coast. The portion of SR 1 north of the project site is an officially designated Scenic Highway by Caltrans. However, the project site is not visible from either US 101 or SR 1; therefore, impacts would be less than significant. The State and City have designated highways that offer scenic views as Scenic Highways. The City has identified US 101 from the southern city limit to Marsh Street as a highway with high scenic value, and between Marsh and Broad Streets and north of California Street as a highway with moderate scenic value. Santa Rosa Street north of Foothill Boulevard and past the northern city limit is designated as having moderate to high scenic value. The project site is accessed from Santa Rosa Street to Westmont Avenue from the east, Stanford Drive from the southwest, and Westmont Avenue from the west. The Patricia Drive Entrance to the Bishop Peak Trailhead is located 0.5 mile northwest of the proposed project site. Views of the proposed housing tract from Bishop Peak and associated trails would be consistent with current existing views of developed residential units. Currently, there is no specific development planned for the parcels. It can be assumed that each parcel will be developed as a single-family residential use, with an ADUs and JADUs as potential accessory uses in accordance with State law. Construction of future residences, ADUs, and JADUs may result in additional tree removal, potential earthwork, and impervious surface area; however, the specifics of which are not known at this time. The project currently proposes a subdivision of a single parcel (APN 052-496-001) into 23 lots; grading of the project site; development of a road to connect Stanford and Cuesta Drives; installment of necessary utility, drainage, and bicycle/pedestrian easement; and necessary tree removal. Future residential development on these parcels would need to comply with City ordinances for R-1 (Low Density Residential) development outlined in Sections 17.16 and 17.70 of the City Municipal Code and with the COSE, which outlines view guidelines regarding urban development (Policy 9.1.2). The COSE states that urban development should reflect its architectural context. This does not necessarily prescribe a specific style, but requires deliberate design choices that acknowledge human scale, natural site features, and neighboring urban development, and that are compatible with historical and architectural resources. As mentioned above, improvements would require the removal of trees and a potential removal of a rock outcropping located on the western portion of the project site. The COSE states that scenic and unique landforms, including significant trees or outcroppings, should be preserved. Proposed tree removal would be consistent with the City’s Tree Ordinance, which establishes requirements for compensatory planting (1:1) and preservation requirements for retaining trees with historic or unusual value. The rock outcropping is located between proposed Lots 1 and 2 and depending on final construction plans would likely be removed. The outcropping is neither scenic or unique (such as those of the Morros) and any impacts or removal of it as a result of the project would be insignificant and not in conflict with policies of the COSE. Additionally, none of the trees onsite have historic or unusual value. Therefore, the proposed project is consistent with applicable zoning and the City of San Luis Obispo General Plan, and impacts would be considered less than significant. The project is not currently proposing the development of outdoor lighting sources that could create a new source of light or glare. Future development plans have not been specified; however, if new light sources are proposed, they must adhere to the COSE (Policy 9.2.3), which states outdoor lighting shall avoid operating at unnecessary locations, levels, and times; spillage into areas not needing or wanting illumination; glare; and frequencies that interfere with astronomical viewing. Outdoor lighting standards include, but are not limited to, a requirement for outdoor light sources to be shielded and directed away from adjacent properties and public rights-of-way, minimum levels of lighting consistent with public safety standards, and limits to hours of lighting operation. Future residential development would be required to comply with the Lighting and Night Sky Preservation Ordinance (Section 17.70.100). The project would also be subject to Page 79 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 14 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 review and approval by the City Community Development Director to ensure compliance with these standards prior to final approval. Therefore, impacts from new sources of light or glare would be less than significant. Mitigation Measures No mitigation is required. Conclusion The project site is not located within a scenic vista or within the viewshed of a designated State Scenic Highway and is consistent with existing views visible from Santa Rosa Street. The project does not propose any design features that are inconsistent with the current zoning regulations or other applicable regulations. Therefore, impacts would be less than significant. 2. AGRICULTURE AND FORESTRY RESOURCES In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significan t Impact No Impact a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? 2, 9 ☐ ☐ ☐ ☒ b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? 2, 10 ☐ ☐ ☐ ☒ c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? 2, 3, 8 ☐ ☐ ☐ ☒ d) Result in the loss of forest land or conversion of forest land to non-forest use? 1 ☐ ☐ ☒ ☐ e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? 1, 2, 9, 10 ☐ ☐ ☐ ☒ Evaluation The California Department of Conservation (CDOC) classifies and maps agricultural lands in the state in the Farmland Mapping and Monitoring Program (FMMP). The FMMP identifies five farmland categories: Prime Farmland, Farmland of Statewide Page 80 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 15 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Importance, Unique Farmland, Farmland of Local Importance, and Farmland of Local Potential. The project site is designated as Urban and Built-Up Land by the FMMP. No portion of the project site or immediately surrounding areas support active agricultural uses. The project site is not loc ated within or immediately adjacent to land zoned for agricultural uses. Based on Figure 6 in the COSE, the project site is not located within or immediately adjacent to land under an active Williamson Act contract. According to Public Resources Code (PRC) Section 12220(g), forest land is defined as land that can support 10% native tree cover of any species, including hardwoods, under natural conditions, and that allows for management of one or more forest resources, including timber, aesthetics, fish and wildlife, biodiversity, water quality, recreation, and other public benefits. Timberland is defined as land, other than land owned by the federal government and land designated by the State Board of Forestry and Fire Protection as experimental forest land, which is available for, and capable of, growing a crop of trees of a commercial species used to produce lumber and other forest products, including Christmas trees. According to FMMP designations, the project site is located on Urban and Built-Up Land (DOC 2020). Since the project site is not located on land designated as Farmland by the FMMP, the project would not result in the conversion of Farmland to non-agricultural use; therefore, no impacts would occur. The closest Prime Farmland is located approximately 530 feet east of the project just beyond Santa Rosa Street; however, this area is not zoned for agricultural uses under the City’s COSE. The proposed project would not disturb the FMMP designated Prime Farmland or interfere with agricultural zoning designations. The project site and adjacent land are not under a Williamson Act contract. The closest land under a Williamson Act contract is located approximately 0.87 mile west on the opposite side of Bishop Peak. Proposed improvements would not affect nearby land under a Williamson Act contract or conflict with nearby land that is zoned for agricultural uses; therefore, the project would not conflict with existing agricultural zoning or a Williamson Act contract, and no impacts would occur. The project site is currently zoned as R-1 (Low Density Residential) and is surrounded by R-1 (Low Density Residential) zoning designations to the north, west, and south and open space to the east. Therefore, the project site does not include land use designations or zoning for forest land or timberland. The project would not conflict with zoning for forest land, timberland, or timberland zoned Timberland Production, and no impacts would occur. The project site contains more than 10% of native tree cover resulting from coast live oaks (Quercus agrifolia) located primarily along the northern and eastern property lines. While these trees provide an aesthetic benefit to the project site, they are not present in such a quantity to provide for significant management of forest resources. Subdivision improvements would require the removal of native trees, and pursuant to the City’s Tree Regulations (City Municipal Code Chapter 12.24), the project would be required to compensate for removed trees at a minimum 1:1 ratio. Therefore, the project’s impact related to loss or conversion of forest land, timberland, or timberland zoned Timberland Production would be less than significant. The project site is surrounded low-density residential uses to the north, west, and south and open space to the east. The nearest agricultural uses are approximately 530 feet east of the project site. The proposed project would be consistent with surrounding uses and consistent with existing zoning for this site and would not adversely affect agricultural water supplies or other agricultural support facilities. Therefore, the project would not result in substantial changes in the environment that could result in conversion of nearby agricultural land or forest land to non-agricultural or non-forest use, and no impacts would occur. Mitigation Measures No mitigation is required. Conclusion The project site is located in an urbanized area and is not within or adjacent to Farmland, land zoned for agricultural or fo rest land use, or land under a Williamson Act Contract. No potentially significant impacts to agriculture or forest land would occur, and no mitigation is necessary.

AIR QUALITY Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Conflict with or obstruct implementation of the applicable air quality plan? 11, 12, 13 ☐ ☐ ☒ ☐ b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? 11, 12, 13 ☐ ☒ ☐ ☐ c) Expose sensitive receptors to substantial pollutant concentrations? 1, 3, 12, 13 ☐ ☒ ☐ ☐ d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? 1, 14 ☐ ☒ ☐ ☐ Evaluation The city of San Luis Obispo is located within the South Central Coast Air Basin (SCCAB), which also includes Santa Barbara and Ventura Counties. Air quality within the SCCAB is regulated by several jurisdictions including the U.S. Environmental Protection Agency (EPA), California Air Resources Board (CARB), and San Luis Obispo County Air Pollution Control District (SLOAPCD). The SLOAPCD monitors air pollutant levels to assure that air quality standards are met, and if they are not met, develops strategies to meet the standards. Depending on whether the standards are met or exceeded, the SCCAB is classified as being in “attainment” or as “nonattainment.” San Luis Obispo County is currently designated as “nonattainment” for the State standards for ozone, partial nonattainment (in eastern San Luis Obispo County, outside of the project area) for federal ambient standards for ground-level ozone (O3), and nonattainment for the State standards for particulate matter less than 10 microns in diameter (PM10). The COSE identifies goals and policies to achieve and maintain air quality that supports health and enjoyment for those who live, work, and visit the c ity. These goals and policies include meeting federal and State air quality standards, reducing dependency on gasoline- or diesel- powered motor vehicles, and encouraging walking, biking, and public transit use. The major sources of PM10 in the SCCAB are agricultural operations, vehicle dust, grading, and dust produced by high winds. Additional sources of particulate pollution include diesel exhaust, mineral extraction and production, combustion products from industry and motor vehicles, smoke from open burning, paved and unpaved roads, condensation of gaseous pollutants into liquid or solid particles, and wind-blown dust from soils disturbed by demolition and construction, agricultural operations, off-road vehicle recreation, and other activities. Ozone is a secondary pollutant that is formed by a reaction between nitrogen oxides (NOx) and reactive organic gases (ROGs) in the presence of sunlight. Therefore, ozone levels are dependent on the amount of these precursors. In the SCCAB, the major sources of ROGs are motor vehicles, organic solvents, petroleum production, and pesticides. The major sources of NOx are motor vehicles, public utility power generation, and fuel combustion by various industrial sources. The SLOAPCD has developed a California Environmental Quality Act (CEQA) Air Quality Handbook (most recently updated with a November 2017 Clarification Memorandum) to evaluate project-specific impacts and determine if potentially significant impacts could result from a project. To evaluate long-term emissions, cumulative effects, and establish countywide programs to reach acceptable air quality levels, the 2001 San Luis Obispo County Clean Air Plan (CAP) was adopted by the SLOAPCD. Some land uses are considered more sensitive to changes in air quality than others, depending on the population groups and the activities involved. The CARB has identified the following groups that are most likely to be affected by air pollution (i.e., sensitive receptors): children under 14, the elderly over 65 years of age, athletes, and people with cardiovascular and chronic respiratory diseases. The nearest sensitive receptors to the project site are the single-family residences located adjacent to the south (10 feet), west (20 feet), and east (10 feet) of the project site. Page 82 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 17 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Naturally Occurring Asbestos (NOA) has been identified as a toxic air contaminant by the CARB. Any ground disturbance or demolition of existing structures in an area identified as having the potential to contain NOA must comply with the CARB Airborne Toxics Control Measure (ATCM) for Construction, Grading, Quarrying, and Surface Mining Operations. The SLOAPCD NOA Map indicates that the project site is located within an area identified as having a potential for NOA to occur. In order to be considered consistent with the 2001 San Luis Obispo County CAP, a project must be consistent with the land use planning and transportation control measures (TCMs) and strategies outlined in the CAP. The proposed project is consistent with the general level of development anticipated and projected in the CAP. The proposed development’s location, uses, and intensity are generally consistent with planning envisioned in the 2014 City of San Luis Obispo General Plan Land Use and Circulation Elements (LUCE) update and with the CAP’s land use planning strategies. The project is located within the City’s urban reserve line and would not designate more land for urban use, would be in close proximity to public transportation, and supports compact communities’ strategies. Increases in housing units would help to offset projected imbalances between jobs and housing units, as noted in the 2019 Regional Housing Needs Allocation Plan (RHNA) prepared by the San Luis Obispo Council of Governments (SLOCOG). Improvements in a jobs-to-housing imbalance would help support and promote local and regional improvements related to increased transportation mobility and potential reductions in vehicle miles traveled (VMT). The proposed project does not include commercial or industrial land uses that would result in increases in employment. The proposed project would be consistent with the general level of development anticipated and projected in the CAP. Therefore, potential impacts would be less than significant. Construction of the subdivision improvements would disturb approximately 4.27 acres of land and result in emissions of ROGs, NOx, and fugitive dust emissions (PM10). The parcel subdivision would facilitate future single-family residential uses, with ADUs and JADUs as potential accessory uses, that would result in emissions of pollutants during construction activity. During operation, the project would result in emissions of ozone precursor pollutants associated with mobile source emissions and other uses. Construction Emissions Proposed subdivision improvements would disturb approximately 4.27 acres of land and require approximately 12,600 cy of total earthwork; however, specific future development plans are currently unknown and have the potential to result in additional ground disturbance causing the production of more pollutants. Construction of subdivision improvements and future residential structures have the potential to cause a short-term increase in dust and vehicle emissions, including diesel particulate matter (DPM), ROGs, NOx, and particulate matter. As shown in Table 2, construction emissions from proposed subdivision improvements would exceed the SLOAPCD’s applicable screening thresholds for ROG, NOx, DPM, or PM10. Therefore, potential construction-related emissions of these pollutants would require SLOAPCD Tier 1 mitigation as described in Mitigation Measures AQ-1 and AQ-2. Table 2. Project Construction Emissions Criteria Pollutant Total Project Emissions SLOAPCD Screening Threshold Exceeds Threshold? Reactive Organic Gases (ROG) + Nitrogen Oxide (NOx) 0.72 tons 2.5 tons/quarter No Diesel Particulate Matter (DPM) 0.03 tons 0.13 tons/quarter Yes Fugitive Particulate Matter (PM10) 3.20 tons 2.5 tons/quarter Yes It is anticipated that the subdivision improvements and construction of single-family residential uses, with an ADUs and JADUs as potential accessory uses, would occur sequentially. Exact grading volumes for the residential development are unknown at this time but would likely involve less than 4 acres of site disturbance and 1,200 cy of earthwork per day, which would not result in exceedances of the SLOAPCD thresholds. To minimize potential impacts, AQ-1 and AQ-2 would be applicable to the residential development. Therefore, potential impacts would be less than significant with mitigation. Page 83 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 18 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Operational Emissions The SLOAPCD CEQA Air Quality Handbook provides operational screening criteria to identify projects with the potential to exceed SLOAPCD operational significance thresholds (see Table 1-1 of the CEQA Air Quality Handbook). Based on Table 1-1 of the CEQA Air Quality Handbook, the project does not propose development that would have the potential to result in operational emissions that would exceed SLOAPCD thresholds (76 single-family residences). Based on the relatively low volume of trips associated with the project and the type of activities proposed, operational impacts associated with the project would be minimal. The project would not generate substantial new long-term traffic trips or vehicle emissions and does not propose construction of substantial new direct (source) emissions. Therefore, potential operational emissions would be less than significant. The project site is located within 1,000 feet of multiple sensitive receptors, including single-family residential units to the south, east, and west of the project site. The development of single-family residential uses, with ADUs and JADUs as potential accessory uses, would result in temporary construction vehicle emissions and fugitive dust that may affect surrounding sensitive receptors. The SLOAPCD CEQA Air Quality Handbook recognizes special conditions, such as proximity to sensitive receptors, that require implementation of standard construction mitigation measures to reduce diesel idling (DPM) and fugitive dust. Due to the project’s proximity to surrounding residential areas (less than 1,000 feet), standard measures for reducing DPM and fugitive dust are required. Mitigation Measures AQ-1 and AQ-2 would reduce exposure of sensitive receptors to adverse fugitive dust and construction vehicle emissions; therefore, impacts would be less than significant with mitigation. Project development activities, such as building construction, utility trenching, and installation, would generate odors associated with equipment exhaust and fumes. The proposed activities would not differ significantly from those resulting from any other type of construction project. Any effects would be short term in nature limited to the construction phase of the proposed project and would be less than significant. The SLOAPCD NOA Map indicates that the project site is located within an area identified as having a potential for NOA to occur. The project includes excavation for road construction and trenching and installation of new water, wastewater, and stormwater service pipelines to the proposed new parcels. The project may also include demolition of an existing barn and shed, which have the potential to disturb asbestos-containing materials (ACM). Demolition can have potential negative air quality impacts, including issues surrounding proper handling, demolition, and disposal of ACM. Future development of the parcels would also likely include excavation for foundations and trenching for utilities. Pursuant to SLOAPCD requirements and the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (17 California Code of Regulations [CCR] Section 93105), the applicant is required to conduct a geologic evaluation prior to any ground-disturbing activities and comply with existing regulations regarding NOA, if present. Mitigation Measures AQ-3 and AQ-4 have been identified to require the applicant to complete a geologic evaluation and follow all applicable protocols and procedures if NOA is determined to be present onsite. Mitigation Measure AQ- 5 requires inspection for ACM prior to demolition and reported to the SLOAPCD. Based on compliance with identified mitigation and existing regulations, this potential impact would be less than significant with mitigation. Mitigation Measures AQ-1 Idling Control Techniques. During all construction activities and use of diesel vehicles, the applicant shall implement the following idling control techniques: 1. Idling Restrictions Near Sensitive Receptors for Both On- and Off-Road Equipment. a. Staging and queuing areas shall not be located within 1,000 feet of sensitive receptors if feasible; b. Diesel idling within 1,000 feet of sensitive receptors shall not be permitted; c. Use of alternative-fueled equipment shall be used whenever possible; and d. Signs that specify the no idling requirements shall be posted and enforced at the construction site. 2. California Diesel Idling Regulations. On-road diesel vehicles shall comply with 13 CCR 2485. This regulation limits idling from diesel-fueled commercial motor vehicles with gross vehicular weight ratings of more than 10,000 pounds and licensed for operation on highways. It applies to California- and non- California-based vehicles. In general, the regulation specifies that drivers of said vehicles: Page 84 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 19 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 a. Shall not idle the vehicle’s primary diesel engine for greater than 5 minutes at any location, except as noted in Subsection (d) of the regulation; and b. Shall not operate a diesel-fueled auxiliary power system (APS) to power a heater, air conditioner, or any ancillary equipment on that vehicle during sleeping or resting in a sleeper berth for greater than 5 minutes at any location when within 1,000 feet of a restricted area, except as noted in Subsection (d) of the regulation. Signs must be posted in the designated queuing areas and job sites to remind drivers of the 5-minute idling limit. The specific requirements and exceptions in the regulation can be reviewed at the following website: www.arb.ca.gov/msprog/truck-idling/2485.pdf. AQ-2 Particulate Matter Control Measures. During all construction and ground-disturbing activities, the applicant shall implement the following particulate matter control measures and detail each measure on the project grading and building plans: 1. Reduce the amount of disturbed area where possible. 2. Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site and from exceeding the SLOAPCD’s limit of 20% opacity for greater than 3 minutes in any 60-minute period. Increased watering frequency would be required whenever wind speeds exceed 15 miles per hour (mph). Reclaimed (non-potable) water should be used whenever possible. 3. All dirt stockpile areas (if any) shall be sprayed daily and covered with tarps or other dust barriers as needed. 4. Permanent dust control measures identified in the approved project revegetation and landscape plans shall be implemented as soon as possible, following completion of any soil-disturbing activities. 5. Exposed grounds that are planned to be reworked at dates greater than 1 month after initial grading shall be sown with a fast germinating, non-invasive, grass seed and watered until vegetation is established. 6. All disturbed soil areas not subject to revegetation shall be stabilized using approved chemical soil binders, jute netting, or other methods approved in advance by the SLOAPCD. 7. All roadways, driveways, sidewalks, etc. to be paved shall be completed as soon as possible. In addition, building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. 8. Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved surface at the construction site. 9. All trucks hauling dirt, sand, soil, or other loose materials are to be covered or shall maintain at least 2 feet of freeboard (minimum vertical distance between top of load and top of trailer) in accordance with California Vehicle Code (CVC) Section 23114. 10. “Track out” is defined as sand or soil that adheres to and/or agglomerates on the exterior surfaces of motor vehicles and/or equipment (including tires) that may then fall onto any highway or street as described in CVC Section 23113 and California Water Code (CWC) Section 13304. To prevent track out, designate access points and require all employees, subcontractors, and others to use them. Install and operate a “track-out prevention device” where vehicles enter and exit unpaved roads onto paved streets. The track- out prevention device can be any device or combination of devices that are effective at preventing track out, located at the point of intersection of an unpaved area and a paved road. Rumble strips or steel plate devices need periodic cleaning to be effective. If paved roadways accumulate tracked-out soils, the track- out prevention device may need to be modified. 11. Sweep streets at the end of each day if visible soil material is carried onto adjacent paved roads. Water sweepers shall be used with reclaimed water where feasible. Roads shall be pre-wetted prior to sweeping when feasible. 12. All PM10 mitigation measures required should be shown on grading and building plans. 13. The contractor or builder shall designate a person or persons whose responsibility is to ensure any fugitive dust emissions do not result in a nuisance and to enhance the implementation of the mitigation measures Page 85 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 20 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 as necessary to minimize dust complaints and reduce visible emissions below the SLOAPCD’s limit of 20% opacity for greater than 3 minutes in any 60-minute period. Their duties shall include holidays and weekend periods when work may not be in progress (for example, wind-blown dust could be generated on an open dirt lot). The name and telephone number of such persons shall be provided to the SLOAPCD Compliance Division prior to the start of any grading, earthwork, or demolition (Contact Tim Fuhs at 805-781-5912). AQ-3 Geologic Evaluation. Prior to initiation of ground-disturbing activities, the applicant shall retain a registered geologist to conduct a geologic evaluation of the property, including sampling and testing for NOA in full compliance with SLOAPCD requirements and the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105). This geologic evaluation shall be submitted to the City Community Development Department upon completion. If the geologic evaluation determines that the project would not have the potential to disturb NOA, the applicant must file an Asbestos ATCM exemption request with the SLOAPCD. AQ-4 Naturally Occurring Asbestos Control Measures. If NOA are determined to be present onsite, proposed earthwork, demolition, and construction activities shall be conducted in full compliance with the various regulatory jurisdictions regarding NOA, including the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105) and requirements stipulated in the National Emission Standard for Hazardous Air Pollutants (NESHAP; 40 Code of Federal Regulations [CFR] Section 61, Subpart M – Asbestos). These requirements include, but are not limited to, the following: 1. Written notification, within at least 10 business days of activities commencing, to the SLOAPCD; 2. Preparation of an asbestos survey conducted by a Certified Asbestos Consultant; and 3. Implementation of applicable removal and disposal protocol and requirements for identified NOA. AQ-5 Asbestos-Containing Material. Prior to issuance of demolition permits, the applicant shall provide an asbestos report that was prepared by a certified asbestos consultant. If ACM are determined to be present, at least 10 working days prior to any demolition work the applicant shall provide notification to SLOAPCD of such work. The notification shall include an asbestos report that was prepared by a certified asbestos consultant. ACM removal and disposal shall follow the requirements of the National Emission Standards for Hazardous Air Pollutants Regulation (NESHAP) Subpart M and of the SLOAPCD. Conclusion With implementation of Mitigation Measures AQ-1 through AQ-5, residual impacts associated with air quality would be less than significant. 4. BIOLOGICAL RESOURCES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? 1, 4, 5, 62, 63, 64 ☐ ☒ ☐ ☐ b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? 1, 4, 5, 64 ☐ ☒ ☐ ☐ Page 86 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 21 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? 2, 4, 5, 17, 62, 64 ☐ ☒ ☐ ☐ d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? 4, 5, 64 ☐ ☒ ☐ ☐ e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? 7, 16 ☐ ☐ ☒ ☐ f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? 18 ☐ ☐ ☐ ☒ Evaluation The city is generally surrounded by open space, rangeland used for grazing, and other agricultural uses that support a variety of natural habitats and plant communities. The city’s many creeks provide sheltered corridors that allow local wildlife to move between habitats and open space areas. The COSE identifies various goals and policies to maintain, enhance, and protect natural communities within the City’s planning area. These policies include, but are not limited to, protection of listed species and species of special concern, preservation of existing wildlife corridors, protection of significant trees, and maintaining development setbacks from creeks. The project site is zoned R-1 (Low Density Residential) and is surrounded by developed one- and two-story single-family residential units to the south, east, and west, undeveloped land to the north, and CAL FIRE Station #12 to the east. The Patricia Drive entrance to the Bishop Peak Trailhead is located 0.5 mile northwest. A creek and associated freshwater forested/shrub wetland and riparian areas occur on the western portion of the project site and connects to a freshwater emergent wetland on the northern undeveloped parcel. According to the Biological Resources Assessment (BRA) conducted by Keven Merk Associates, LLC (KMA; KMA 2020), there are five plant communities/land use types within the project site. The communities include ornamental vegetation, developed/ruderal area, riparian habitat, annual grassland, and rock outcrop. KMA identifies the onsite creek as Twin Ridge Creek, which runs in a north to south direction on the western portion of the project parcel and is a tributary to San Luis Obispo Creek. The riparian habitat is comprised of native coast live oak and willows (Salix spp.) along with a variety of non-native ornamental vegetation. The riparian habitat is considered a sensitive natural community by the California Department of Fish and Wildlife (CDFW) and the City’s COSE. The annual grassland that occurs on the project site is periodically used for horse grazing and is predominantly comprised of non-native species as a result of a history of disturbance. There is one small rock outcrop in the western portion of the project area that was determined to be a landscape feature rather than a habitat type. During tree surveys, a total of 177 trees were identified on the project site, which include ornamental species and naturally occurring native species. Native trees include coast live oak (quercys agrifolia), valley oak (quercus lobata), Southern California black walnut (juglans California), California bay laurel (Umbellularia california), arroyo willow (salix lasiolepis), and California holly toyon (heteromeles arbutifolia). A background review for the site identified five special-plant species that have potential to occur within the project site, with three species—Cambria morning glory, California black walnut (Juglans californica), and Monterey pine (Pinus radiata)—occurring onsite. Three invertebrate, one reptile, 19 bird, and four mammal species were considered to have potential to occur on the project site. Fish species are not expected to occur onsite due to the intermittent nature of the drainage. The project site is considered within Unit SLO-3 of designated critical habitat for the California red-legged frog (Rana draytonii). Unit SLO-3 is approximately 116,517 acres in size and identifies a geographic area that contains features essential for the conservation of the species. Activities on private lands that do not require a federal Page 87 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 22 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact permit are not affected by the critical habitat designation (FWS 2010). The following analysis of biological resources is primarily based off the BRA conducted by KMA for the project (KMA 2020, KMA 2021). An Aquatic Resources Delineation Report prepared by SWCA Environmental Consultants (SWCA) in January 2021 determined that a portion of the wetland area supported onsite is considered Waters of the United States (WOTUS) under the U.S. Army Corps of Engineers (USACE) and Waters of the State (WOTS) under the state Regional Water Quality Control Board (RWQCB) and CDFW. Special-Status Plant Species The BRA for the project site determined that there is potential for four special-status plant species to occur onsite, of which three species (Cambria morning glory, California black walnut, and Monterey pine) were observed onsite. Potential special-status plant species include California (southern) black walnut (California Rare Plant Rank [CRPR] 4.2, Cambria morning glory (CRPR 4.2), Miles’ milk-vetch (Astragalus didymocarpus var. milesianus; CRPR 1B.2), and San Luis Obispo owl’s-clover (Castilleja densiflora var. obispoensis; CRPR 1B.2). In addition, Monterey pine was observed within ornamental vegetation onsite and in surrounding neighborhood areas and is considered to be a CRPR 1B.1 only within its native range of Año Nuevo, Cambria, and the Monterey Peninsula. These species are considered to have potential to occur onsite based on the presence of suitable soils and habitat conditions. Focused rare plant surveys were conducted for the project site within all potentially suitable habitat areas in March, April, and May 2020, which is within the blooming period of these four species with potential to occur onsite. Based on the findings of the surveys, Miles’ milk-vetch and San Luis Obispo owl’s-clover was not observed during field surveys and would not be affected by project activities. Cambria morning glory and California black walnut were observed onsite and are discussed below. In addition, the BRA identifies Monterey pine species present within ornamental vegetation and is also discussed below. Cambria Morning Glory Cambria morning glory was observed within the annual grassland, which comprises the project site to the east of the onsite wetland and riparian habitat. The occurrences supported low densities with average cover estimated at three plants per square meter. The four observed occurrences were determined to cover approximately 1,076 sf (100 square meters) of the project site and approximately 300 plants were present onsite. Construction of the project, including grading and installation of road and utility improvements, as well as future residential development, would result in the removal or disturbance of Cambria morning glory. Implementation of Mitigation Measures BIO-1 and BIO-2 are required to reduce potential impacts to Cambria morning glory. These measures would require implementation of a Rare Plan Mitigation Program that would establish replanting of Cambria morning glory so that after a 5-year period there would be no net loss of the plant. Implementation of recommended mitigation measures would reduce impacts to a level that is considered less than significant with mitigation. Monterey Pine Monterey pine was observed within the ornamental trees onsite and in surrounding neighborhoods. Monterey pine is considered to be a CRPR 1B.1 species within its native range. The three native stands in California are in Año Nuevo, Cambria, and the Monterey Peninsula. Similar to the California black walnut, since San Luis Obispo is not within this species’ native range, the Monterey pine would not be considered a special-status species onsite and no mitigation is recommended. Special-Status Wildlife Species Based on a background review for the project site, 19 bird, three invertebrate, one reptile, and four mammal species have potential to occur on the project site. No fish species were determined to have potential to occur onsite based on the intermittent nature of the drainage. The species that have potential to occur onsite are discussed below. Page 88 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 23 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Birds and Bats The 19 bird species identified as having the potential to occur onsite include bald eagle (Haliaeetus leucocephalus), burrowing owl (Athene cunicularia), California horned lark (Eremophila alpestris actia), Cooper’s hawk (Accipiter cooperii), ferruginous hawk (Buteo regalis), golden eagle (Aquila chrysaetos), grasshopper sparrow (Ammodramus savannarum), great blue heron (Ardea herodias), great egret (Ardea alba), loggerhead shrike (Lanius ludovicianus), merlin (Falco columbarius), northern harrier (Circus cyaneus), prairie falcon (Falco mexicanus), sharp-shinned hawk (Accipiter striatus), snowy egret (Egretta thula), tricolored blackbird (Agelaius tricolor), white-tailed kite (Elanus leucurus), yellow-billed magpie (Pica nuttallii), yellow warbler (Setophaga petechia), pallid bat (Antrozous pallidus), San Diego desert woodrat (Neotoma lepida intermedia), Townsend’s big-eared bat (Corynorhinus townsendii), and western mastiff bat (Eumops perotis californicus). The project site is comprised of numerous ornamental and native trees and other habitat that have the potential for birds or bats to nest or roost in. Burrowing owls have the potential to occur onsite, as a transient species, during the winter months due to large grassland habitat to the north of the site. According to CDFW, burrowing owls are rare in the coastal San Luis Obispo area and are believed to no longer nest in the region (KMA 2021, CDFW 2003). Additionally, the project site is regularly disturbed (i.e. mowed, grazed) which reduces the potential for burrowing owl to stop at the site as this species is highly sensitive to human activity, and the project site is located within an existing residential neighborhood. Additionally, wintering habitat for burrowing owl has the potential to be disturbed during proposed groundwork activity. The project would remove 13 non-native trees within the riparian habitat, primarily acacia (silver wattle) trees and one eucalyptus tree. Removal of trees for parcel upgrades and future development have the potential for accidental take or other indirect affects to bird species in the area. Additionally, as noted in the Initial Study circulated for public review, wintering habitat for burrowing owl has the potential to be disturbed during proposed groundwork activity. Implementation of Mitigation Measures BIO-3 through BIO-7 would reduce impacts to nesting or roosting birds and bats that could be present at the project site. Implementation of these mitigation measures would reduce project impacts on birds to a level that is considered less than significant with mitigation. Reptiles The northern California legless lizard (Anniella pulchra) is a CDFW Species of Special Concern (SSC) and occurs in a variety of habitats with soil moisture and cover. Suitable habitat for this species is present in the riparian habitat and marginally in the ornamental vegetation onsite. While no construction activity is proposed within the riparian habitat, non-native acacia trees within the riparian corridor and adjacent native and ornamental vegetation outside of the riparian corridor would be removed, and therefore could impact California legless lizard. Implementation of Mitigation Measures BIO-4 through BIO-7 would reduce impacts to northern California legless lizard to a level that is considered less than significant with mitigation. Invertebrates The monarch butterfly (Danaus plexippus) is considered a sensitive species by the CDFW and is a candidate species under the Endangered Species Act. Milkweed is required as a host plant for caterpillar species, which was not observed onsite; however, individual species were observed flying overhead during surveys. The density of trees in the riparian habitat could potentially be suitable habitat as an overwintering or autumnal site. Tree removal is proposed for parcel upgrades and could affect monarch butterfly species present onsite. While eucalyptus is a typical tree species that supports monarch butterfly overwintering, removal of the one eucalyptus tree and 13 non-native trees from the riparian corridor would not have a substantial adverse effect on monarch butterfly overwintering populations, and restoration of the creek corridor and adjacent areas would include the replanting and establishment of native species, including Cambria morning glory onsite, that would provide protected foraging habitat onsite and potential overwintering or autumnal habitat for this species in the long-term within the riparian corridor. Implementation of Mitigation Measure BIO-8 would require vegetation removal to occur outside of the overwintering season; therefore, impacts would be less than significant with mitigation. The obscure bumble bee (Bombus caliginosus) does not have a specific listing status but is considered sensitive in the California Natural Diversity Database (CNDDB) and is a species of local concern. The BRA identified that host plants for these species are located in riparian habitat onsite. The riparian habitat would have a 20-foot setback and minimal Page 89 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 24 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact work within the setback would be required. However, acacia tree removal is proposed within the riparian habitat that has the potential to disturb obscure bumble bee species present within the riparian habitat. Implementation of Mitigation Measures BIO-4 through BIO-8 would reduce impacts to obscure bumble bee species to a level that is considered less than significant with mitigation. The San Luis Obispo pyrg (Pyrgulopsis taylori) is an aquatic snail that is considered sensitive by CNDDB but does not have a specific listing status. The species inhabits freshwater habitat, which is present at the onsite creek. Project activities do not propose alteration or disturbance of the creek that could adversely affect San Luis Obispo pyrg species potentially present. Standard Best Management Practices (BMPs) to reduce erosion and sedimentation within the creek habitat would be sufficient to avoid impacts to potential species present onsite. Standard BMPs are identified in Mitigation Measure BIO-9 and would reduce impacts to the San Luis Obispo pyrg to a level that is considered less than significant with mitigation. Designated Critical Habitat The project site is considered designated critical habitat for the California red-legged frog by the U.S. Fish and Wildlife Service (USFWS). The area is Unit SLO-3 Willow and Toro Creeks to San Luis Obispo and comprises approximately 116,517 acres. The unit occurs along the San Luis Obispo Coast, north of Morro Bay, and extends southeast into the city of San Luis Obispo. Critical habitat areas identify a geographic area that contains features essential for the conservation of the species. Activities on private lands that do not require a federal permit are not affected by the critical habitat designation. However, listed species, such as red-legged frog, and their habitats, are protected by the Endangered Species Act regardless of whether they occur in a designated critical habitat or not. (FWS 2010). The BRA concluded that the project site does not provide suitable aquatic breeding habitat for California red-legged frog. The onsite drainage portion of Twin Ridges Creek is intermittent and does not contain water of sufficient depth long enough for California red-legged frog larvae to complete metamorphosis. At the time of the March 2020 site visit, only one small pool was identified with less than six inches of standing water. No emergent wetland vegetation was present, and wetland vegetation along the channel consisted of vernal marsh species, which indicated a lack of permanent inundation (KMA 2021). In addition, the stream lacks any significant pools and does not contain sufficient depth to support adult frogs. Typical breeding habitat is associated with still or slow-moving water that is more than two feet in depth and is surrounded by dense, shrubby riparian or emergent vegetation. Additionally, breeding pools maintain water at least into July (KMA 2021). Based on the site visit and aerial photography of the site vicinity, there are no other potential breeding ponds nearby that could support California red-legged frog. Annual grassland and ornamental habitats are considered suitable upland and dispersal habitat for California red-legged frog if there are aquatic breeding sites within one mile that are not separated by barriers to dispersal.; however, the The nearest record of California red-legged frog is 0.4 mile at Brizziolari Creek, which is separated from the project site by SR 1, which is a barrier to movement and dispersal to and from the project site. The project site does not provide connections to other suitable aquatic sites and is surrounded by urban development to the south, west, and east. A comment received on the draft MND suggested that a perennial portion of Twin Ridges Creek exists downstream of the project site and could potentially provide suitable habitat for California red-legged frog. The identified segment is not mapped in the National Wetlands Inventory but is identified on a 1965 San Luis Obispo U.S. Geologic Survey topographic quadrangle as an intermittent stream that originates on the east side of Bishop Peak (KMA 2021). This drainage was visited by the project biologist, Kevin Merk, on June 10, 2021. The drainage originates from a storm drainpipe and has a small pool at the outfall (6 feet wide, 14 feet long, and 4 inches deep). Based on channel morphology and evidence of past flow events, this pool would likely reach a maximum depth of 18 inches (1.5 feet), which is less than the 2 feet of depth observed at typical breeding sites for California red-legged frog. Two additional pools occur downstream from this outfall pool, with water two to three inches deep and no flow between the pools. The maximum size of these pools is estimated at 3 feet by 5 feet, and 6 inches deep, and 2 feet by 3 feet and 4 inches deep; therefore, both pools would have a maximum depth less than the 2 feet of depth observed at typical breeding sites for California red-legged frog. Page 90 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 25 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact As noted in the supplemental memorandum prepared by KMA (2021), residential structures are present along the top of bank and the streambank below the homes is armored with stacked concrete sacks. Extensive cover of nonnative English ivy occurs throughout the area. Sparse wetland plants were observed in the channel and consisted of a small patch of sedges with taller riparian canopy cover comprised mostly of willows. This native amphibian needs deep enough water to dive into to escape predators such as raccoons and wading birds (USFWS, 2002; Jennings and Hayes, 1994 [as cited in the KMA, 20210 memorandum). The non-native bullfrog is also a known predator of California red-legged frog. When California red-legged frog tadpoles are found in streams they are in large pools with emergent wetland plants, overhanging riparian vegetation in contact with the water or undercut banks that provide the necessary hiding places to avoid predation so they can develop into young adults (USFWS, 2002; KMA personal observation). Although water persisted in the small culvert outfall pool until June in a drought year, it is too shallow and limited in extent even at the estimated bank full stage to support California red-legged frog breeding requirements. The segment of the drainage on the project site and extending further upstream to another culverted section that daylights from under urban development along Skyline Drive naturally dries in the summer and does not have any in-channel pools with suitable depth to support red-legged frogs. The commenter identified this as the “spring origin”, and it appears to be another outfall of the culverted creek that has become overgrow n with weedy vegetation including several Canary Island palm trees. Additionally, there is no downstream habitat for California red-legged frog as Twin Ridges Creek goes into an open concrete channel downstream from Highland Drive (City 2014). Moreover, no records of California red-legged frogs are present from Stenner Creek or San Luis Obispo Creek within the downtown area where individuals could breed and disperse through the creek corridor onto the site (CDFW 2021). In conclusion, these pools are too shallow (less than 2 feet in maximum depth) and do not provide enough overhanging riparian vegetation in contact with the water or banks to provide necessary shelter from the elements and predation for red-legged frog tadpoles to develop into young adults. Therefore, the site is considered to have low potential for breeding habitat or upland and dispersal habitat for California red-legged frog within the designated critical habitat and impacts would be less than significant. The project site supports identified special-status plants and wildlife species that could be affected by the proposed project. However, implementation of Mitigation Measures BIO-1 through BIO-9 would reduce or avoid potential impacts to biological resources present onsite; therefore, impacts would be less than significant with mitigation. The project site contains a riparian forest along the onsite creek located in the western portion the property. The BRA identifies the riparian habitat as a Central Coast Live Oak Riparian Forest Community, which has a State Rarity Rank of 3.2. The identified riparian forest consists of native riparian trees and shrubs, which includes coast live oak, red willow (Salix laevigata), arroyo willow (Salix lasiolepis), toyon, California bay laurel (Umbellularia californica), interior live oak (Quercus wislizenii), and California black walnut (Juglans californica). Non-native species also occur in the riparian habitat, including blue gum (Eucalyptus globulus), silver wattle (Acacia dealbata), firethorn (Pyracantha sp.), coast redwood (Sequoia sempervirens), and English ivy (Hedera helix). Native understory plants present within the riparian area include poison oak (Toxicodendron diversilobum), and coyote brush (Baccharis pilularis). A separate wetland community was observed in the riparian area, which includes spikebrush (Eleocharis macrostachya), brown- headed rush (Juncus phaeocephalus), tall flatsedge (Cyperus eragrostis), and curly dock (Rumex crispus). The project would require permits described in Mitigation Measure BIO-10 for work proposed within the riparian area. In addition, the Fire Protection Plan requires removal of non-native trees within the riparian habitat, resulting in the removal of 13 trees, primarily acacia (silver wattle) trees and one eucalyptus tree, within the riparian habitats corridor. The project would be required to comply with the City’s Municipal Code (12.24.090) and replace trees at a minimum 1:1 ratio. The City’s COSE (7.7.9) calls for a creek setback with appropriate separation from the physical top of bank unless there is no reasonable alternative, in which structures may be permitted to encroach. The proposed TTM shows the extent of the riparian area and a 20-foot creek setback, which would be further protected by implementation of mitigation measure BIO-11, which requires recordation of a biological easement on the Final Map and application of creek setback standards. As noted, improvements including stormwater improvements, removal of non-native trees and plants, and restoration activities would be allowed within the easement area. No paving or structures would be permitted in the Page 91 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 26 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact biological easement area, however, grading activity is proposed in several areas within the creek setback for stabilization, and placement of rip rap pads are proposed within or adjacent to the setback. The easement and application of creek setback standards would affect proposed Lots 1–8.;.. With implementation of the identified mitigation measure, the project would reduce impacts to the riparian area onsite and impacts would be less than significant with mitigation. Proposed project construction requires 4.27 acres of ground disturbance, including 7,900 cy of cut and 4,760 cy of fill, which has the potential to release erosive runoff into the creek and associated wetland areas that may cause adverse effects to water quality. Mitigation Measure BIO-9 identifies construction BMPs to reduce potential runoff from the project site that could adversely affects nearby water resources. In addition, an Aquatic Resources Delineation Report was prepared by SWCA (SWCA 2021) as required by the BRA and determined that Twin Ridge Creek is likely non- wetland WOTUS and waters of the state. Twin Ridge Creek likely falls under the USACE, CDFW, and RWQCB jurisdictions due to the presence of clearly definable ordinary high-water marks, bank and bed features, riparian vegetation, and hydrologic connectivity to San Luis Obispo Creek. Twin Ridge Creek does not meet the definition of a wetland because it does not support hydric soils or consistent indicators of wetland hydrology. The Aquatic Resources Delineation determined that 0.14 acre of Twin Ridge Creek is potentially under the jurisdiction of the USACE and 0.70 acre of the riparian area is potentially under the jurisdiction of the RWQCB and CDFW. The project identifies a 20- foot setback from the riparian edge in accordance with the City’s COSE, and this area would be further protected from future development by implementation of Mitigation Measure BIO-11, which would create a biological easement; however, some grading activity and placement of rip rap pads would occur within or adjacent to the creek setback, and several non-native trees would be removed from within the riparian corridor for fire safety. The project would require permits described in Mitigation Measure BIO-10 for work proposed within the jurisdictional areas (streambed and riparian corridor). With implementation of the identified mitigation measures, potential impacts to the riparian area onsite would be reduced and impacts would be considered less than significant with mitigation. The project site is located near an area designated as a wildlife corridor within the COSE. The proposed property subdivision, utility connections, and subsequent future development of new residences would not introduce a substantial new barrier to wildlife passing through the area because they would be located outside of the designated wildlife corridor. Regarding common wildlife, the project site is zoned for residential development, and is surrounded on three sides by the existing residential neighborhood, and the Cal Fire facility is located to the northeast. One existing residence is currently located on Stanford Drive. The vacant land to the north of the site is located along State Route 1 and connects to larger areas of largely vacant land, rural developments, and open space to the north and west. While common wildlife adapted to urban development may approach the project site and surrounding neighborhood, development of the project site would not block or inhibit wildlife movement throughout the larger undeveloped and open space lands that extend from the City to the coastline (approximately 8.5 miles to the west). Furthermore, the project incorporates a 20-foot setback from the riparian corridor that will be enhanced by the removal of non-native trees and the planting of native vegetation, and wildlife that currently uses this corridor to access the larger areas to the north would not be blocked or inhibited by the proposed project. Therefore, the proposed residential development of the 4.98-acre site would not interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites. Public comment was received regarding concern that the removal of trees within the riparian corridor would decrease roosting habitat for raptors. The proposed project would include the removal of only non-native species for fire protection, and potential short-term impacts to nesting birds is discussed above (see [a]) and mitigation is identified to reduce these potential short-term impacts to less than significant (Mitigation Measures BIO-3 through BIO-7). In the long-term, the riparian corridor would be replanted with native trees, shrubs, and grasses and protected in perpetuity. Therefore, the habitat condition of the riparian corridor will improve overall area that is occupied by native riparian habitat will increase. The onsite grassland area is currently disturbed and does not represent high quality foraging habitat given its limited area and proximity to existing urban development. Raptors would still be able to utilize trees along the riparian corridor and in the surrounding area for perches even with the Page 92 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 27 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact development of the proposed project. The BRA determined that the onsite creek, Twin Ridge Creek, does not support fish species due to the intermittent nature of the drainage; therefore, project activities do not have the potential to interfere with the movement of migratory fish species within the creek. However, according to the BRA, Twin Ridge Creek is a tributary to San Luis Obispo Creek and potential erosive runoff from the project has the potential to degrade water quality and fish species within San Luis Obispo Creek. Mitigation Measure BIO-9 identifies BMPs for construction activity to reduce potential erosion and sedimentation from entering the onsite creek, which would reduce the potential for erosion and sedimentation to enter San Luis Obispo Creek. In addition, implementation of Mitigation Measure BIO-11 would create a permanent biological easement and application of a 20-foot setback standard from the riparian edge, which would be consistent with the City’s Municipal Code (17.70.030). Future development would be consistent with the City’s Municipal Code (17.70.030) and implementation of Mitigation Measure BIO-9 would reduce impacts to the movement of migratory or native species; therefore, impacts would be less than significant with mitigation. The project site supports Central Coast Live Oak Riparian Forest and other native and non-native trees. The project site contains 177 ornamental and native trees, primarily within the riparian corridor. The project would remove all 73 trees located outside the riparian corridor including 15 native coast live oak trees and 1 southern California black walnut tree (tree numbers 1-62, 85-91, 173-177 as shown in Appendix D of Attachment 3 and Sheet C2 of Attachment 2). Additionally, the Fire Protection Plan for the proposed project requires removal of non-native trees within the riparian habitat. A total of 13 non-native trees, primarily acacia (silver wattle) trees, within the riparian corridor would be removed (tree numbers 114, 148-157, 162, 169, as shown in Appendix D of Attachment 3 and Sheet C2 of Attachment 2). The project would result in the removal of 86 trees total onsite. Of the 86 trees proposed for removal, 51 trees are subject to the City’s Tree Ordinance, due to species, trunk size, or location within a creek setback. Based on the compensatory tree planting requirements of the City’s Tree Ordinance, the applicant will be required to replant a minimum of one new tree onsite, or two offsite, for each of the 51 being removed, as set forth in the City Municipal Code (12.24.090). This application is subject to review and approval by the City Tree Committee. The project would not result in a conflict with local policies or ordinances protecting biological resources. Therefore, impacts would be less than significant. The project is not located within an area governed by an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved state, regional, or local habitat conservation plan. Therefore, the project would not conflict with the provisions of an adopted plan and no impacts would occur. Mitigation Measures BIO-1 Implement a Rare Plant Mitigation Program that ensures no net loss of Cambria morning glory on the project site. Prior to any tract improvements, a Rare Plant Mitigation Program shall be implemented for Cambria morning glory and shall be overseen by a qualified botanist approved by the City. As a component of the program, seed shall be collected from Cambria morning glory plants during the appropriate season prior to tract grading activities. Using standard procedures, the qualified botanist shall clean and store the seeds until the receiving sites shown on the project plans are ready. Suitable habitat of 2,180 square-feet in size outside of the development area (as designated on the site plans in the creek setback zone) shall be designated as the mitigation site that will be maintained in a natural state and not be subject to mowing earlier than June 1 each year. The areas will be maintained as grassland habitat and no planting of ornamental species or other adverse modifications (such as grazing activities) will be allowed. The mitigation site shown on the project plans is twice the size as the areas currently occupied by the rare plant occurrences (2,180 square-feet of habitat created for 1,076 square-feet of habitat impacted). This equates to a 2:1 mitigation ratio (habitat created to habitat impacted) to ensure a minimum 1:1 replacement ratio is achieved. Topsoil from each of the four occurrences will be collected in 6-inch lifts and stored for top-dressing the mitigation site once grading of the pads is complete. As needed, the mitigation site should be prepared for planting by removal of non-native species or other measures as necessary, then applying the salvaged topsoil. Once topsoil has been layered evenly through the area, collected seed should be hand-broadcasted into suitable locations by the qualified botanist and covered with compost. Seed may also be incorporated into the native Page 93 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 28 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact erosion control seed mix described in the Native Erosion Control Seed Mix table under Mitigation Measure BIO-9 and applied to other grassy areas of the site as part of the erosion control effort. Depending on the season when construction starts, the qualified botanist may also potentially salvage plants (i.e., dig them up when soils are moist) and transplant them to containers to be maintained until the mitigation sites are ready for planting. BIO-2 Conduct annual monitoring and implement adaptive management measures for 5 years to ensure no net loss of Cambria morning glory onsite. The Rare Plant Mitigation Program shall include annual monitoring and maintenance of the mitigation site to ensure success of the program. Monitoring by a qualified botanist shall occur during the spring growing season (between April 15 and May 15 each year) to ensure successful establishment of planted propagules. The established rare plants shall be mapped to evaluate the goal of no net loss of the species onsite. The measurable objective shall be to have at least 1,076 sf of occurrence comprised of approximately 300 Cambria morning glory plants. Appropriate vegetation sampling techniques shall be used to assess the areal cover of vegetation to evaluate the status of the established occurrences. If the success criteria of having approximately 300 plants covering 1,076 sf within the creek setback zone is not reached by the third year of monitoring, remedial actions such as collecting more seed and distributing it in suitable areas should be employed, with a corresponding additional year of monitoring. Other activities to increase the success of the rare plant mitigation effort could include non-native plant species removal within the mitigation site to reduce competition, additional seed application, or supplemental irrigation during periods of prolonged drought. The qualified botanist shall prepare annual reports for the applicant detailing the methods and results of the mitigation effort and monitoring effort. The applicant shall be responsible for submitting the report to the City on an annual basis (by December 31 of each year) for the 5-year monitoring period or until the final success criteria described above are met. BIO-3 To the extent feasible, avoid initial site grading in the winter months. The burrowing owl has been recorded in the vicinity of the project from October to the end of April. If initial vegetation removal and site grading for the tract improvements is conducted outside of this period, potential effects on this species would be avoided and no further mitigation would be required. Restricting the time period for earth-moving activities is also required to avoid or minimize the potential for erosion and sedimentation (see Mitigation Measure BIO-9). If initial grading work must commence during the time period that burrowing owls may be present onsite, preconstruction surveys for this species shall be included in the survey effort described in Mitigation Measure BIO-4 prior to vegetation removal or tract improvements. BIO-4 Conduct a preconstruction survey and avoid construction in areas occupied by special-status wildlife species until relocated or they have left the site. Within 7 days prior to the start of vegetation/tree removal, ground- disturbing activities, or demolition of existing structures, a biologist approved by the City shall survey the project impact area to identify whether nesting birds, roosting bats, monarch butterfly overwintering populations, obscure bumble bee, and/or California legless lizard are present on site. A separate survey shall be conducted for any phase of the project not conducted concurrently or within 10 days of cessation of the previous phase (i.e., structure demolition conducted prior to general site grading). The biologist shall use appropriate survey techniques for the special-status species identified in the 2020 BRA as having potential to occur onsite. For example, burrows shall be examined with binoculars or wildlife cameras, and inspected for whitewash or prey remains. Leaf litter and cover objects shall be searched for northern California legless lizards. Potential bat roost sites shall be inspected for sign of roosting bats such as guano or prey remains. If any of these species are found onsite, the biologist shall coordinate with the City, and CDFW as appropriate, on methods to ensure the successful relocation of individuals to suitable habitat nearby. In some cases, CDFW may recommend creating structures for displaced woodrats and bats. Burrowing owls can be discouraged from using burrows onsite, or occupied burrows can be avoided until the owls have left the area. Bats can be restricted from roost sites by placing netting over their entrances after they have left the roost for night-time foraging. The wildlife protection measures to be employed will be based on the results of the survey and the particular characteristics of their use of the site, in coordination with CDFW and the construction engineer. If no special-status animal species are found onsite during the preconstruction survey, work may proceed with the implementation of the following Mitigation Measures BIO-5 through BIO-7. Page 94 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 29 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact BIO-5 Prepare and present a Worker Environmental Awareness Program. Prior to any vegetation removal or tract improvements, a qualified biologist shall prepare a Worker Environmental Awareness Program that will be presented to all project personnel. This program shall detail measures to avoid and minimize impacts on biological resources. It shall include a description of special-status species potentially occurring on the project site and their natural history, the status of the species and their protection under environmental laws and regulations, and the penalties for take. Recommendations shall be given as to actions to avoid take should a special-status species be found on the project site. Other aspects of the training shall include a description of general measures to protect wildlife, including: 1. Delineation of the allowable work area, staging areas, access points, and limits to vehicle access; 2. Storage of all pipes, metal tubing, or similar materials stored or stacked on the project site for one or more overnight periods shall be either securely capped before storage or thoroughly inspected for wildlife before the materials are moved, buried, capped, or otherwise used. 3. Inspection of materials stored onsite, such as lumber, plywood, and rolls of silt fence, for wildlife that may have sheltered under or within the materials; 4. Use of netting to exclude birds from nesting in construction materials; 5. Construction of escape ramps in all excavations and trenches more than 6 inches deep; 6. Contact information for the City-approved biologist and instructions should any wildlife species be detected in the work site; 7. Dust suppression methods during construction activities when necessary to meet air quality standards and protect biological resources; and 8. Methods for containment of food-related trash items (e.g., wrappers, cans, bottles, food scraps), small construction debris (e.g., nails, bits of metal and plastic), and other human generated debris (e.g., cigarette butts) in animal-proof containers and removal from the site on a weekly basis. All project personnel who have attended the training shall sign an attendance sheet. The program shall be repeated for any new crews that arrive subsequently on the site. BIO-6 Install high-visibility construction and silt fence along the creek corridor to delineate the allowable work area, exclude wildlife from the site, and protect the stream habitat. Prior to vegetation removal or tract improvements, and during subsequent residential development for Lots 1-7, a high-visibility construction fence at least 4 feet tall together with a silt fence, or an approved wildlife exclusion fence, shall be erected along the creek corridor to delineate the limits of grading and vehicle access. If possible, the fence shall be erected along the creek setback line, and encroachment into the setback shall be kept at a minimum. In no case shall ground disturbance occur within the riparian habitat or below the top of bank without obtaining proper permits from regulatory agencies. The type of fence used may be a combination of wildlife exclusion and silt fence (i.e., ERTEC Triple-function E-fence) or similar materials that would serve the purposes of safety/construction area delineation, wildlife exclusion, and siltation prevention. The fence shall be checked weekly by construction personnel for needed maintenance. BIO-7 Conduct biological monitoring for special-status wildlife species while the property is cleared and graded, and structures are removed. A qualified biologist shall monitor the removal of structures, materials, and vegetation that may provide cover for obscure bumble bee, northern California legless lizards, and bat roosting sites. The biologist shall be onsite daily until all materials are removed and all vegetation has been cleared. If any special-status species are found, work shall be delayed until the individuals have left the work area or CDFW shall be notified to obtain authorization for capture and relocation. Page 95 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 30 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact BIO-8 Avoid vegetation removal within the riparian habitat during the overwintering season. Vegetation removal within the riparian area shall be conducted outside of the overwintering season for monarch butterfly (late October through February) and obscure bumble bee (late October through January) to avoid disturbance to species potentially inhabiting riparian vegetation. BIO-9 Install erosion and sediment BMPs and revegetate graded areas. The following erosion and sedimentation control BMPs are required to be implemented during vegetation removal, tract improvements, during individual lot construction, and after the construction phases of the project: 1. If possible, the potential for erosion and sedimentation shall be minimized by scheduling construction to occur outside of the rainy season, which is typically defined as October 15 through April 15. Adherence to this measure would also serve as avoidance for the burrowing owl, as described in Mitigation Measure BIO-3. 2. To minimize site disturbance, all construction related equipment shall be restricted to established roads, construction areas, and other designated staging areas. The creek setback zone shall be clearly marked as described in Mitigation Measure BIO-6. 3. Prior to any site disturbance during tract improvements or individual lot construction, a Sediment and Erosion Control Plan shall be prepared by a qualified engineer. The use of silt fence, straw wattles, erosion control blankets, straw bales, sandbags, fiber rolls, and other appropriate techniques should be employed to protect the drainage features on and off the property. Biotechnical approaches using native vegetation shall be used as feasible. All areas with soil disturbance shall have appropriate erosion controls and other stormwater protection BMPs installed to prevent erosion potential. All sediment and erosion control measures shall be installed per the engineer’s requirements prior to the initiation of site grading if planned to occur within the rainy season. 4. Spill kits shall be maintained on the site, and a Spill Response Plan shall be in place. 5. No vehicles or equipment shall be refueled within 100 feet of wetland areas, riparian habitat and/or drainage features, and refueling areas shall have a spill containment system installed. No vehicles or construction equipment shall be stored overnight within 100 feet of these areas unless drip pans or ground covers are used. All equipment and vehicles shall be checked and maintained on a daily basis to ensure proper operation and to avoid potential leaks or spills. Construction staging areas shall be located in a location where spills would not drain into aquatic habitats. 6. No concrete washout shall be conducted on the site outside of an appropriate containment system. Washing of equipment, tools, etc. should not be allowed in any location where the tainted water could enter onsite drainages. 7. The use of chemicals, fuels, lubricants, or biocides shall be in compliance with all local, state, and federal regulations. All uses of such compounds shall observe label and other restrictions mandated by the U.S. Environmental Protection Agency, California Department of Food and Agriculture, and other state and federal legislation. 8. All project-related spills of hazardous materials within or adjacent to the project site should be cleaned up immediately. 9. All areas with soil disturbance shall have appropriate erosion controls and other stormwater protection BMPs installed to prevent erosion potential. Silt fencing, erosion control blankets, straw bales, sandbags, fiber rolls, and/or other types of materials prescribed on the plan shall be implemented to prevent erosion and sedimentation. Biotechnical approaches using native vegetation shall be used as feasible. 10. Areas with disturbed soils shall be restored under the direction of the project engineer in consultation with a qualified restoration ecologist as detailed above. Methods may include recontouring graded areas to blend in with existing natural contours, covering the areas with salvaged topsoil containing native Page 96 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 31 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact seedbank from the site, and/or applying the native seed mix as described in the table below. Native seed mix shall be applied to the graded areas in the creek setback area through either direct hand seeding or hydroseeding methods. Seeding with the native erosion control seed mix should be provided on all disturbed soil areas prior to the onset of the rainy season (by October 15). Native Erosion Control Seed Mix Species Application Rate (lbs/acre) California Brome (Bromus carinatus) 10 purple needlegrass (Stipa pulchra) 5 tomcat clover (Trifolium wildenovii) 5 six weeks fescue (Vulpia microstachys) 5 Total 25 BIO-10 Obtain necessary permits for impacts in jurisdictional areas, implement a compensatory mitigation program, and monitor the success of the program to ensure no net loss of Riparian/Wetland habitat or other waters on the subject property. Prior to any vegetation removal or site disturbance within the areas delineated as jurisdictional features (Figure 5, Aquatic Resources Delineation 2021), the applicant shall provide documentation to the City that a Clean Water Act Section 404 Permit from USACE, a Clean Water Act Section 401 Water Quality Certification from RWQCB, and a California Fish and Game Code Section 1602 Lake and Streambed Alteration Agreement from CDFW have been obtained or have been determined by the regulatory agencies to not be required. If regulatory permits are required, Prior to the initiation of vegetation removal or tract improvements, the applicant shall retain a qualified biological monitor to ensure compliance with all Clean Water Act, City of San Luis Obispo stormwater and water quality requirements, and CDFW permit requirements during work adjacent to the creek. The monitor shall be present during the installation of the construction fencing delineating the limits of work in relation to the edge of riparian, creek top of bank, and 20-foot creek setback buffer, as described in Mitigation Measure BIO-6. Since the Cambria morning glory compensatory mitigation site is to be located within this buffer, the monitor shall direct appropriate wildlife exclusion and erosion control BMPs to protect riparian habitat during site preparation for planting. The monitor shall be present during construction of the rip rap pad and any other work within the creek setback area on stormwater structures. The monitor shall also oversee removal of non-native tree species and site preparation for tree planting within the setback. If a Habitat Mitigation and Monitoring Plan (HMMP) is required by the regulatory agencies, the applicant shall provide a copy of the plan to the City and the biological monitor shall be responsible for successful implementation of the plan. BIO-11 Record a Biological Easement and Biological Easement Agreement protecting riparian area: A Biological Easement and Biological Easement Agreement shall be recorded in conjunction with the final map recordation. The easement agreement shall be developed by the applicant in a format provided by the City. The following activities are permitted within the biological easement, subject to the review and approval by the City Sustainability and Natural Resources Official: 1. Stormwater improvements. 2. Removal of non-native trees. 3. Restoration and creek bank stabilization activities. No future paving or structures shall be permitted within the biological easement. Creek setback standards shall be applied to the easement area, consistent with municipal code requirements. Page 97 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 32 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact Conclusion The project site supports native and ruderal plant species as well as Cambria morning glory, which is a special-status plant species, and several riparian and ornamental tree species. The site also supports special-status wildlife habitat that could be affected by the proposed project. Mitigation measures have been identified to reduce or avoid impacts to special-status plants and wildlife species. A wetland area is supported on the western portion of the project area and a 20-foot setback would be implemented from the riparian edge of the area. In addition, mitigation has been identified to reduce impacts to construction activity within the riparian area. Tree removal associated with the project would be mitigated through compliance with the City’s Tree Ordinance but could result in impact to nesting birds and roosting bats. Compliance with existing regulations would ensure impacts to riparian habitats and sensitive natural communities would be less than significant. With implementation of Mitigation Measures BIO-1 through BIO-11, project impacts to biological resources would be less than significant. 5. CULTURAL RESOURCES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Cause a substantial adverse change in the significance of a historic resource pursuant to §15064.5? 19, 20 ☐ ☐ ☒ ☐ b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? 59 ☐ ☒ ☐ ☐ c) Disturb any human remains, including those interred outside of formal cemeteries? 59 ☐ ☒ ☐ ☐ Evaluation Pre-Historic Setting Archaeological evidence demonstrates that Native American groups (including the Chumash) have occupied the Central Coast for at least 10,000 years. The city is located within the area historically occupied by the Obispeño Chumash, the northernmost of the Chumash people of California. The Obispeño Chumash occupied much of San Luis Obispo County; the earliest evidence of human occupation in the region comes from archaeological sites along the coast. The project site is not located within a Burial Sensitivity Area as identified in COSE Figure 1: Cultural Resources. Historic Setting The COSE establishes various goals and policies to balance cultural and historical resource preservation with other community goals. These policies include, but are not limited to, the following: 1. Identification, preservation, and rehabilitation of significant historic and architectural resources; 2. Prevention of demolition of historically or architecturally significant buildings unless doing so is necessary to remove a threat to health and safety; 3. Consistency in the design of new buildings in historical districts to reflect the form, spacing , and materials of nearby historic structures; and 4. Identification and protection of neighborhoods or districts having historical character due to the collective effect of Contributing or Master List historic properties. Page 98 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 33 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The project site is not located within the Historic Preservation (H) Overlay Zone, nor does it contain any built structures that may be considered potentially eligible historic resources. The following analysis of Cultural Resources is predominately based on the Cultural Resources Survey conducted by Central Coast Archaeological Resource Consultants (CCARC) for the project site (CCARC 2020). The project proposes to demolish the two existing residential structures located on the project site; however, the residential units were not determined to have historical significance by the Cultural Resources Survey conducted for the project. Therefore, the project site does not currently contain, nor is it located near, any historic resources identified in the National Register of Historic Places (NRHP) or California Register of Historical Resources (CRHR). The project site is not identified on the City’s Historic Properties map; therefore, the project would not result in a substantial adverse change in the significance of, or any other adverse impact to, a historical resource and impacts would be less than significant. The Cultural Resources Report conducted by CCARC in February 2020 concluded that despite the project site’s location on land with moderate archaeological sensitivity, desktop review and an intensive archaeological field survey of the project site did not identify any cultural resources. Based on this conclusion, no further archaeological survey is necessary for the project site. However, based on the large scale of grading and earthwork required for the project, Mitigation Measure CR-1 has been identified to identify the proper procedures and contact in the event an inadvertent discovery of an archaeological or historical resource is made. Implementation of Mitigation Measure CR-1 would reduce impacts in the event an archaeological resource is uncovered during excavation and other groundwork activities during project construction; therefore, impacts would be less than significant with mitigation. The project site is not located within a Burial Sensitivity Area associated with San Luis Obispo Creek identified in COSE Figure 1: Cultural Resources. No human remains are known to exist within the project site; however, the discovery of unknown human remains is a possibility during ground-disturbing activities. Protocol for properly responding to the inadvertent discovery of human remains is identified in California Health and Safety Code Section 7050.5 and is detailed in Mitigation Measure CR-2. With implementation of Mitigation Measure CR-2, potential impacts to human remains would be less than significant with mitigation. Mitigation Measures CR-1 Discovery of Previously Unidentified Cultural Resources. In the event that historical or archaeological remains are discovered during ground-disturbing activities associated with the project, an immediate halt work order shall be issued, and the City Community Development Director shall be notified. A qualified archaeologist shall conduct an assessment of the resources and formulate proper mitigation measures, if necessary. After the find has been appropriately mitigated, work in the area may resume. These requirements shall be noted on the project’s final map and all improvement/construction plans. CR-2 Discovery of Human Remains. In the event that human remains are exposed during ground-disturbing activities associated with the project, an immediate halt work order shall be issued, and the City Community Development Director shall be notified. California Health and Safety Code Section 7050.5 requires that no further disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains shall occur until the County Coroner has made the necessary findings as to origin and disposition pursuant to PRC Section 5097.98. If the remains are determined to be of Native American descent, the coroner shall notify the Native American Heritage Commission (NAHC) within 24 hours. These requirements shall be noted on the project’s final map and all improvement/construction plans. Conclusion Based on the records search conducted through the Central Coast Information Center, no known historical or archaeological resources are present onsite. Mitigation Measures CR-1 and CR-2 have been identified above to require appropriate protocol for inadvertent resource discovery and discovery of human remains. With implementation of Mitigation Measures CR-1 and CR-2 identified above, potential impacts to cultural resources would be reduced to less than significant.

ENERGY Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? 21, 22, 23 ☐ ☐ ☒ ☐ b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? 21, 22, 23 ☐ ☐ ☒ ☐ Evaluation PG&E has historically been the primary electricity provider for the City. In October 2018, the City Council committed to joining the Monterey Bay Community Power (MBCP) and, beginning in January 2020, MBCP became the City’s primary electricity provider. In September 2020, MBCP became Central Coast Community Energy (3CE); 3CE will strive to provide 100% carbon- free electricity to utility customers within the city by 2030, and provides a rate savings relative to PG&E. The City recently adopted the Clean Energy Choice Program for New Buildings, which encourages clean, efficient, and cost- effective all-electric new buildings through incentives and local amendments to the California Energy Code. When paired with cost-comparable modern electric appliances and carbon-free electricity from 3CE, all-electric new buildings are operationally greenhouse gas (GHG) emissions free, cost effective, and help achieve the community’s climate action goals. Unlike other cities that are banning natural gas entirely, the proposed Clean Energy Choice Program encourages clean, efficient, and cost-effective all-electric new buildings through incentives, local amendments to the California Energy Code, and implementation of the Carbon Offset Program. New projects wishing to use natural gas will be required to build more efficient and higher performing buildings and offset natural gas use by performing retrofits on existing buildings or by paying an in-lieu fee that will be used for the same purpose. The California Building Code (CBC) contains standards that regulate the method of use, properties, performance, or types of materials used in the construction, alteration, improvement, repair, or rehabilitation of a building or other improvement to real property. The CBC includes mandatory green building standards for residential and nonresidential structures, the most recent version of which are referred to as the 2019 Building Energy Efficiency Standards. These standards focus on four key areas: smart residential photovoltaic systems, updated thermal envelope standards (preventing heat transfer from the interior to the exterior and vice versa), residential and nonresidential ventilation requirements, and nonresidential lighting requirements. The COSE establishes goals and policies to achieve energy conservation and increase use of cleaner, renewable, and locally controlled energy sources. These goals include increasing the use of sustainable energy sources and reducing reliance on non- sustainable energy sources to the extent possible and encouraging the provision for and protection of solar access. Policies identified to achieve these goals include, but are not limited to, use of best available practices in energy conservation, procurement, use, and production; energy-efficiency improvements; pedestrian- and bicycle-friendly facility design; fostering alternative transportation modes; compact, high-density housing; and solar access standards. The City of San Luis Obispo Climate Action Plan for Community Recovery also identifies strategies and policies to increase use of cleaner and renewable energy resources in order to achieve the City’s GHG emissions reduction target. These strategies include promoting a wide range of renewable energy financing options, incentivizing renewable energy generation in new and existing developments, and increasing community awareness of renewable energy programs. The Climate Action Plan was updated in August 2020. During construction, fossil fuels, electricity, and natural gas would be used by construction vehicles and equipment. The energy consumed during construction would be temporary in nature and would be typical of other similar construction activities in the city. Current federal and state regulations require fuel-efficient equipment and vehicles and prohibit wasteful activities, such as diesel idling; therefore, potential impacts associated with construction energy use would be less than significant. Page 100 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 35 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Specific development plans are currently unknown; however, it can be assumed that each parcel will be developed as a single-family residential use, with ADUs and JADUs as potential accessory uses. Based on this assumption, the project would result in an overall increase in consumption of energy resources associated with vehicle trips and electricity and natural gas usage by future project occupants. The project would be designed in full compliance with the CBC and the City’s adopted amendments (Title 15 of the Municipal Code), including applicable green building standards, ensuring a high standard for energy efficiency in building design, materials, light fixtures, and appliances. The project would rely on the local electricity service provider, 3CE, to supply project electricity needs. Compliance with existing regulations would ensure the project would not result in a potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources. Through use of 100% GHG-free electricity resources, project energy use would not result in a significant environmental impact; therefore, impacts would be less than significant. The project would be designed in full compliance with the CBC and the City’s adopted amendments (Title 15 of the Municipal Code), including applicable green building standards. The project would be consistent with energy goals and policies in the COSE associated with use of best available practices in energy conservation. The project would be consistent with other goals and policies set forth in the Climate Action Plan associated with renewable energy or energy efficiency, including the provision of compact, high-density housing. Therefore, the project would not result in a conflict with, or obstruction of, a state or local plan for renewable energy or energy efficiency, and impacts would be less than significant. Mitigation Measures No mitigation is required. Conclusion Future development would be designed in full compliance with applicable energy efficiency standards and would not conflict with state or local plans for renewable energy or energy efficiency. No potentially significant impacts related to energy would occur, and no mitigation measures are necessary. 7.

The Los Osos Fault, adjacent to the city of San Luis Obispo, is identified under the State of California Alquist-Priolo Fault Hazards Act and is classified as active. The West Huasna, Oceanic, and Edna Faults are considered potentially active and present a moderate fault rupture hazard to developments near them. The San Andreas Fault and the offshore Hosgri Fault, which present the most likely source of ground shaking for San Luis Obispo, have a high probability of producing a major earthquake within an average lifespan. The highest risk from g round shaking is found on deep soils that were deposited by water, are geologically recent, and have many pore spaces among the soil grains. These soils are typically found in valleys. Faults capable of producing strong ground-shaking motion in San Luis Obispo include the Los Osos, Point San Luis, Black Mountain, Rinconada, Wilmar, Pecho, Hosgri, La Panza, and San Andreas Faults. Engineering standards and building codes set minimum design and construction methods for structures to resist seismic shaking. Based on the DOC Fault Activity Map and the Safety Element Earthquake Faults – Local Area map, the project site is not located within or within the immediate vicinity of an active fault zone. As discussed in the City’s 2014 LUCE Update Environmental Impact Report (EIR), San Luis Obispo lies within the southern Coast Range Geomorphic Province. This province lies between the Central Valley of California and the Pacific Ocean and extends from Oregon to northern Santa Barbara County. The Coast Range province is structurally complex and comprised of sub-parallel northwest–southeast trending faults, folds, and mountain ranges. Rock types in the San Luis Obispo area are mainly comprised of volcanic rock, metavolcanic rock, and a mixture of serpentinite and greywacke sandstone. These rocks are highly fractured and are part of the Mesozoic-aged Franciscan Formation. Intrusive and extrusive volcanic deposits of Tertiary-age and marine sedimentary deposits of the Miocene-aged Monterey Formation are also found in the area. The most distinctive geomorphological feature of the San Luis Obispo area is the series of Tertiary-aged volcanic plugs (remnants of volcanoes), known as the Nine Sisters or the Morros, that extend from the city of San Luis Obispo northwesterly to the city of Morro Bay. Hollister Peak, Bishop Peak, Cerro San Luis Obispo, Islay Hill, and Morro Rock are all comprised of these volcanic plugs. Seismic-Related Ground Failure Settlement is defined as the condition in which a portion of the ground supporting part of a structure or facility lowers more than the rest or becomes softer, usually because ground shaking reduces the voids between soil particles, often with groundwater rising in the process. Liquefaction is the sudden loss of the soil’s supporting strength due to groundwater filling and lubri cating the spaces between soil particles as a result of ground shaking. Soils with high risk for liquefaction are typically sandy and in creek floodplains or close to lakes. In extreme cases of liquefaction, structures can tilt, break apart, or sink into the gro und. The Page 102 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 37 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 likelihood of liquefaction increases with the strength and duration of an earthquake. Based on the Ground Shaking and Landslide Hazards Map in the Safety Element, the project site is not located within an area of high liquefaction potential. Slope Instability and Landsides Slope instability can occur as a gradual spreading of soil, a relatively sudden slippage, a rockfall, or in other forms. Causes include steep slopes, inherently weak soils, saturated soils, and earthquakes. Improper grading and manmade drainage can be contributing factors. Much of the development in San Luis Obispo is in valleys, where there is low potential for slope instability. Based on the Ground Shaking and Landslide Hazards Map in the Safety Element, the project site is located within an area with moderate landslide potential. Subsidence Land subsidence is a gradual settling or sudden sinking of the earth’s surface due to subsurface movement of earth materials. Primary causes are groundwater withdrawal, in which water is removed from pore space as the water table drops, causing the ground surface to settle; tectonic subsidence, where the ground surface is warped or dropped lower due to geologic factors such as faulting or folding; and earthquake-induced shaking that causes sediment liquefaction, which in turn can lead to ground- surface subsidence. Based on the U.S. Geological Survey (USGS) Areas of Land Subsidence in California Map, the project site is not located in an area of known subsidence. Soil-Limiting Factors The project site is underlain by Los Osos-Diablo complex (9 to 15 percent slopes) and Cropley clay (2 to 9 percent slopes) soil units. The Los Osos-Diablo complex is characterized as well drained with a very high runoff class and Cropley clay is characterized as moderately drained with a moderate runoff class. The project site is underlain by soils that are predominantly clayey and would have a moderate to high shrink/swell potential as a result. The slope of the project site is generally flat to slightly sloping, with an average of 8 percent slopes. Foundations and footings should be designed to offset shrink-swell potential, and the low strength of the clay subsoil. These soil characteristics can require that the subgrade be removed and replaced with a more suitable material or that a high degree of compaction and moisture control be maintained. a.i) The project site is located approximately 2.8 miles east from the Los Osos Fault Zone and 1.9 miles west from the Cambria fault zone. There are no fault lines that run under or adjacent to the project site; therefore, direct impacts related to fault rupture are not anticipated. Because San Luis Obispo is located in a seismically active region, it has adopted building standards to protect structures and individuals. Development plans are not currently specified; however, future development of the proposed parcels would be designed to comply with the CBC (including Title 15 amendments) and other applicable guidelines. Therefore, the project would not have the potential to result in substantial adverse effects involving rupture of a known earthquake fault, and impacts would be less than significant. a.ii, iii) As discussed in (a.i) above, San Luis Obispo is located in a seismically active region where there is always the potential for ground shaking. According to Section 1613 of the 2019 CBC, all structures and portions of structures are required to be designed to resist the effects of seismic loadings caused by earthquake ground motions. Future residential units developed at the project site would comply with the CBC and other applicable regulations for earthquake hazards. According to the City’s Safety Element, soils found at the project site have a low potential for liquefaction risk. Assuming that any and all future development of the project site is compliant with CBC and other federal and state regulations, the potential to result in substantial adverse effects involving seismic ground shaking and ground-related failure would be less than significant. a.iv) According to the City’s Ground Shaking & Landslide Hazards Map, the project site is located in an area that has a low risk for landslides. The project area is comprised of predominantly flat to slightly sloping land and does not consist of moderate to steep slopes that would increase risk for landslides at the proposed site. Future developments would comply with the CBC, which requires, at a minimum, a soils report for new residential development, and other applicable regulations to reduce the potential for the project to result in substantial adverse effects involving landslides to less than significant. b) Proposed project construction requires 4.27 acres of ground disturbance including 7,900 cy of cut and 4,760 cy of fill, which has the potential to release erosive runoff into the creek and associated wetland areas that may cause adverse effects to water quality. Additionally, the project would remove 86 trees, including 13 non-native trees within the Page 103 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 38 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 riparian corridor. The project proposes to disturb more than one-acre of soil and would require the preparation and implementation of a Stormwater Pollution Prevention Plan (SWPPP) with BMPs to avoid or reduce erosive or polluted runoff from entering the onsite creek and associated wetland area. Section 4, Biological Resources, identifies Mitigation Measure BIO-9, which outlines BMPs that would reduce construction impacts related to erosive runoff. Project development would be required to comply with the Central Coast RWQCB requirements set forth in the Post- Construction Stormwater Management Requirements for Development Projects in the Central Coast Region. Future development as a result of the subdivision will be single-family residential uses, with ADUs and JADUs as potential accessory uses, potential removal of additional existing trees, and connections to the proposed utility lines. Grading activity for future development is proposed for current parcel improvements; therefore, it is unlikely that future development would require more than one-acre of groundwork and would not need to develop and implement a SWPPP. However, future development would be required to comply with the Central Coast RWQCB Post-Construction Requirements (PCRs), and physical improvement of the project site would be required to comply with the drainage requirements of the City’s Waterways Management Plan. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. Therefore, through implementation of Mitigation Measure BIO-9 and compliance with existing regulations, impacts related to violation of water quality standards would be less than significant with mitigation. c) According to the City’s Ground Shaking and Landslide Hazards Map, the project site is not located within an area with high landslide or liquefaction potential (City of San Luis Obispo 2014). The soils present at the project site currently support two existing residential units and associated structures and features. Future development would be required to comply with the CBC and other applicable regulations for building standards. Based on compliance with existing regulations and Code requirements, impacts would be less than significant. d) Soils with high shrink/swell potential are predominantly comprised of clay and clay materials. The project site is underlain by soils that contain clay and clay materials; therefore, the soils have a low to moderate shrink/swell potential. The volume changes that soils undergo in this cyclical pattern can stress and damage slabs and foundations. Typical precautionary measures would likely include premoistening the underlying soil in conjunction with placement of non- expansive material beneath slabs, and a deepened and more heavily reinforced foundation. In addition, future development facilitated by implementation of this project would be required to be designed in compliance with standard seismic design criteria established in the CBC to reduce risk associated with ground failure, including from expansive soils. Therefore, based on compliance with existing regulations, impacts related to expansive soils would be less than significant. e) The project would utilize an existing sewage connection and would also include a new connection to the City sewer system. No septic tanks or alternative wastewater treatment systems are proposed onsite. Therefore, no impacts would occur. f) The project site is underlain late Mesozonic sandstones and shales, early to mid-Cenozonic siltstones, igneous and intrusive rock, and quaternary alluvium (CCARC 2020). There are no known paleontological resources on the project site and there are no unique geologic features on the property. For subdivision improvements, 4.27 acres of grading and excavation activity are proposed (i.e., road improvements and utility trenching), and future residential foundations will likely remove expansive soils to comply with the CBC. Based on the low sensitivity of the underlying geologic unit, the lack of proposed activities that would result in significant cuts into bedrock, and the surrounding developed areas, the project would not have the potential to result in impacts to a unique paleontological resource or unique geologic feature, and potential impacts would be less than significant. Mitigation Measures Implement Mitigation Measure BIO-9. Conclusion Based on the location of the project site and underlying geologic and soil properties, and compliance with existing regulatio ns, potential impacts would be less than significant. Parcel improvements have the potential to result in erosion and sedimentation Page 104 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 39 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 that could runoff into nearby water resources. Implementation of Mitigation Measure BIO-9 and compliance with existing regulations would reduce construction impacts related to erosion and impacts to Geology and Soils would be less than significant. 8. GREENHOUSE GAS EMISSIONS Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? 11, 12, 22, 55 ☐ ☐ ☒ ☐ b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? 11, 12, 22, 55 ☐ ☐ ☒ ☐ Evaluation GHGs are any gases that absorb infrared radiation in the atmosphere, and are different from the criteria pollutants discussed in Section 3, Air Quality, above. The primary GHGs that are emitted into the atmosphere as a result of human activities are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. In 2012, the City established a Climate Action Plan that identified measures and implementation strategies in order to achieve the City’s GHG reduction target of 1990 emission levels by 2020. The City’s Climate Action Plan was recently updated and outlines a plan for achieving carbon neutrality by 2035. The City’s 2016 Community Wide GHG emissions inventory showed that 63% of the city’s GHG emissions came from transportation, 13% came from commercial and industrial uses, 11% came from residential uses, and 13% from waste. Statewide legislation, rules, and regulations have been adopted to reduce GHG emissions from significant sources. Senate Bill (SB) 32 and Executive Order (EO) S-3-05 extended the state’s GHG reduction goals and required the CARB to regulate sources of GHGs to meet a state goal of reducing GHG emissions to 1990 levels by 2020, 40% below 1990 levels by 2030, and 80% below 1990 levels by 2050. Other statewide policies adopted to reduce GHG emissions include AB 32, SB 375, and SB 97, as well as the Clean Car Standards, Low Carbon Fuel Standard, Renewable Portfolio Standard, CBC, and California Solar Initiative. The City recently updated its Climate Action Plan. The plan establishes a community-wide goal of carbon neutrality by 2035, adopts sector specific goals, and provides foundational actions to establish a trajectory towards achieving those goals. Appendix C of the Climate Action Plan Update includes thresholds and guidance for the preparation of GHG emissions analysis under CEQA for projects within the City. To support progress toward the City’s long‐term aspirational carbon neutrality goal, plans and projects within the City that undergo CEQA review will need to demonstrate consistency with targets in the Climate Action Plan, a qualified GHG reduction strategy, consistent with State CEQA Guidelines Section 15183.5. According to the adopted SLOAPCD guidance, if a project is consistent with a qualified GHG reduction strategy, such as the City’s Climate Action Plan, the project would not result in a significant impact. In October 2018, the City Council committed to joining 3CE, an existing community choice energy program that serves the counties of Santa Cruz, San Benito, and Monterey and provides 100% carbon-free electricity with a rate savings relative to PG&E. Additionally, the City recently adopted the Clean Energy Choice Program for New Buildings, which encourages clean, efficient, and cost effective all-electric new buildings through incentives and local amendments to the California Energy Code. When paired with cost comparable modern electric appliances and carbon-free electricity from 3CE, all-electric new buildings are operationally GHG emissions free, are cost effective, and help achieve the community’s climate action goals. a, b) Construction-related activities that would generate GHG emissions include worker trips and hauling trips to and from the project site, as well as off-road construction equipment (e.g., dozers, loaders, excavators). Construction activity also requires 4.27 acres of ground disturbance that has the potential to generate ROG and NOx, which are ozone precursors. Impacts related to GHG emissions occur on a global scale and are, therefore, cumulative in nature. Short-term construction-related emissions rarely result in a considerable contribution to GHG emissions. Operational-related activities that would typically generate GHG emissions include residential trips, solid waste disposal, and energy consumption. Page 105 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 40 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The demographic forecasts and land use assumptions of the Climate Action Plan are based on the City’s LUCE. If a plan or project is consistent with the existing 2014 General Plan land use and zoning designations of the project site, then the project would be considered consistent with the demographic forecasts and the land uses assumptions of the Climate Action Plan. The project would be consistent with the land use and zoning designation for the existing parcel; therefore, the project is expected to be consistent with the demographic and land use assumptions used for the development of the City’s latest Climate Action Plan. As discussed previously, the City recently adopted the 2020 Climate Action Plan, which identifies six pillars, each of which include long-term goals, measures, and foundational actions for reducing GHG emissions throughout the city. The pillars include: 1. Leading by Example: Create a Municipal Action Plan by 2020 and achieve carbon-neutral government operations by 2030. 2. Clean Energy Systems: Achieve 100% carbon-free electricity by 2020. 3. Green Buildings: Generate no net new building emissions from on‐site energy use by 2020 and achieve a 50% reduction in existing building on‐site emissions (after accounting for 3CE) by 2030. 4. Connected Community: Achieve the General Plan mode split objective by 2030 and have 40% VMT by electric vehicles by 2030. 5. Circular Economy: Achieve 75% diversion of landfilled organic waste by 2025 and 90% by 2035. 6. Natural Solutions: Increase carbon sequestration on the San Luis Obispo Greenbelt and Urban Forest through compost application-based carbon farming activities and tree planting to be ongoing through 2035. Projects that are consistent with the demographic forecasts and land use assumptions used in the Climate Action Plan can utilize the City’s CEQA GHG Emissions Analysis Compliance Checklist to demonstrate consistency with the Climate Action Plan’s GHG emissions reduction strategy. The proposed project does not propose any new buildings that would be applicable to green building and other energy efficiency standards. Parcel improvements would result in 23 new lots, a new interior connection road, and new utility infrastructure and easements. One of the utility easements would be 17 feet wide and would also be used as bicycle and pedestrian access to and from the site. The proposed project has the potential to developed single-family residential uses, with ADUs and JADUs as potential accessory uses, that would be subject to energy efficiency standards and could increase population and VMT to the project area. The project site is located 0.2 mile north from two bus stops, and additional bus stops are located on Foothill Boulevard approximately 0.5 mile south that would facilitate future residential transit use. In addition, the project is within close walking or biking distance to nearby retail and services, including grocery stores, restaurants, and medical services located approximately 0.56 mile away, which is consistent with the updated Climate Action Plan. Based on the City’s Residential VMT Screening Map, the project is located in an area of the City that would result in average VMT less than or equal to 85% of the regional average, meaning a project in this area would result in reduced VMT. Specific development plans are currently unknown; however, future residential development would likely utilize GHG-free energy through participation in 3CE and with compliance with the City’s Clean Energy Choice Program for New Buildings. New development would also be required to comply with applicable green building standards identified in the updated Climate Action Plan. The project would maintain, where feasible, onsite trees and vegetation and would plant native vegetation at the project site. Based on design elements of the proposed project, the project would be consistent with the goals in the updated Climate Action Plan; therefore, impacts would be less than significant. Mitigation Measures No mitigation is required. Conclusion The project would be located and designed to minimize GHG emissions and would not result in a conflict with an applicable plan or policy adopted for reducing GHG emissions. The project would be consistent with the City’s Climate Action Plan, a qualified GHG reduction strategy. No potentially significant impacts associated with GHG emissions have been identified, and no mitigation measures are necessary.

HAZARDS AND HAZARDOUS MATERIALS Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? 1, 2 ☐ ☐ ☒ ☐ b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? 1, 2 ☐ ☐ ☒ ☐ c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? 1, 2, 3 ☐ ☐ ☒ ☐ d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? 30, 31, 32 ☐ ☐ ☒ ☐ e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working in the project area? 2, 3, 42, 43 ☐ ☐ ☒ ☐ f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? 25 ☐ ☐ ☒ ☐ g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury, or death involving wildland fires? 1, 2, 23, 25 ☐ ☐ ☒ ☐ Evaluation The Hazardous Waste and Substances Site (Cortese) List is a planning tool used by the State, local agencies, and developers to comply with CEQA requirements related to the disclosure of information about the location of hazardous materials release sites. California Government Code Section 65962.5 requires the California EPA (CalEPA) to develop at least annually an updated Cortese List. Various State and local government agencies are required to track and document hazardous material release information for the Cortese List. The California Department of Toxic Substance Control (DTSC) EnviroStor database tracks DTSC cleanup, permitting, enforcement, and investigation efforts at hazardous waste facilities and sites with known contamination, such as federal superfund sites, State response sites, voluntary cleanup sites, school cleanup sites, school investigation sites, and military evaluation sites. The State Water Resources Control Board (SWRCB) GeoTracker database contains records for sites that impact, or have the potential to impact, water in California, such as Leaking Underground Storage Tank (LUST) sites, Department of Defense sites, and Cleanup Program Sites. The remaining data regarding facilities or sites that meet the Cortese List requirements are included on the CalEPA website: https://calepa.ca.gov/sitecleanup/corteselist/. The project does not propose the long-term transportation, use, or disposal of hazardous materials. Short-term construction materials may be transported during development of the proposed improvements to the property and during future development of one- and two-story single-family residences. Hazardous materials would be properly handled to according to federal and State regulations, including response and clean-up requirements for any minor spills. Therefore, potential impacts would be less than significant. The long-term use of the project would be residential units that would not use hazardous materials other than commonly used household substances within the project site (e.g., cleaners, solvents, oils, paints, etc.). Construction of the Page 107 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 42 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 proposed project is anticipated to require use of limited quantities of hazardous substances, including gasoline, diesel fuel, hydraulic fluid, solvents, oils, paints, etc. Construction contractors would be required to comply with applicable federal and State environmental and workplace safety laws for the handling of hazardous materials, including response and clean-up requirements for any minor spills. Therefore, potential impacts would be less than significant. The project site is located approximately 0.47 mile east of Bishop Peak Elementary School. California Polytechnic State University, San Luis Obispo (Cal Poly), is located approximately 500 feet east, across Highway 1. While the project would be located within 0.25 mile of Cal Poly, the eastern portion of the school property that is closest to the project site is developed with experimental agricultural crops. The project site is approximately 0.63 mile from the nearest educational instruction buildings, and approximately 1.0 mile from the onsite residential dormitory areas. Therefore, impacts would be less than significant. According to the CalEPA Cortese List resources, including the DTSC EnviroStor and SWRCB GeoTracker databases, there are no hazardous materials sites on or within 1,000 feet of the project site. Based on the local nature and the existing and historic traffic levels on Stanford Drive, Cuesta Drive, and Westmont Drive, the potential for these roadways to contain hazardous levels of aerially deposited lead (ADL) is negligible. No known mining activities have occurred within or near the project site and no known use of organochlorinated pesticides have occurred. Therefore, impacts would be less than significant. The nearest airport is the San Luis Obispo County Regional Airport, located approximately 4.5 miles south of the project site. The project is not located within the boundaries of the airport land use plan and project development would not adversely impact airport operations. Similarly, airport operations would not result in a substantial safety hazard. Therefore, impacts would be less than significant. The City has identified goals regarding emergency response plans in its Safety Element. The proposed site improvements for future development include the creation of fire safety measures, including an emergency access easement and improved access roads. Project development has the potential to create temporary traffic controls to residential streets but would not result in street closures that would block emergency access. Future development would be designed to comply with building and fire code regulations, as well as City requirements for fire safety; therefore, potential impacts would be less than significant. According to the City’s Wildland Fire Hazards Map, the project is located within a low wildland fire severity zone and surrounding land is located within a moderate wildland fire severity zone. The nearest fire station is San Luis Obispo City Fire Station #2, located approximately 0.56 mile south of the project site on Chorro Street. Emergency response times for the project site are less than 5 minutes. The project would consist of infill development within an existing neighborhood and would not substantially increase wildfire risks. The project proposes the development of improvements for fire hazard safety that include an emergency access easement, upgraded roads, necessary water connections, removal of non-native vegetation and ornamental and native trees, and other measures identified in Mitigation Measures WF-1 and WF-2, included in Section 20, Wildfire. The future development of residential structures would follow CBC and other design regulations for fire hazards. Therefore, people and/or structures would not be exposed to significant risk and the impact would be less than significant with mitigation. Mitigation Measures Implement Mitigation Measures WF-1 and WF-2. Conclusion The project would not result in the routine transportation or storage of hazardous materials. The project is not located on a known hazardous waste site and is not within close proximity to a school or airport. Potential impacts related to hazards, including emergency access and wildfire, would be less than significant.

HYDROLOGY AND WATER QUALITY Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? 34, 35, 41, 65 ☐ ☒ ☐ ☐ b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? 37, 38, 39 ☐ ☒ ☐ ☐ c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: i.

Substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or offsite; 1, 36, 41, 65 ☐ ☒ ☐ ☐ iii. Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or 1, 35, 65 ☐ ☒ ☐ ☐ iv. Impede or redirect flood flows? 36 ☐ ☒ ☐ ☐ d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? 1, 25, 36, 40 ☐ ☐ ☐ ☒ e) Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan? 37, 38, 39, 41 ☐ ☐ ☒ ☐ Evaluation As discussed in the City’s 2014 LUCE Update EIR, the project site is located within the San Luis Obispo Creek Hydrologic Subarea of the Estero Bay Hydrologic Unit, an area that corresponds to the coastal draining watersheds west of the Coastal Range. The Estero Bay Hydrologic Unit stretches roughly 80 miles between the Santa Maria River and the Monterey County line and includes numerous individual stream systems. Within the Estero Bay Hydrologic Unit, the San Luis Obispo Creek watershed drains approximately 84 square miles. The city of San Luis Obispo is generally located within a low-lying valley centered on San Luis Obispo Creek. San Luis Obispo Creek is one of four major drainage features that create flood hazards in the city, with the others b eing Stenner, Prefumo, and Old Garden Creeks. In addition, many minor waterways drain into these creeks, which can also present flood hazards. Because of the high surrounding hills and mountains in the area, the drainage sheds of these creeks are relatively small, but the steep slopes and high gradient can lead to intense, fast-moving flood events in the city. There is an unnamed creek (identified as Twin Ridge Creek) with associated freshwater forested/shrub wetland and riparian areas located in the western portion of the project area. The City is enrolled in the State General Permit National Pollutant Discharge Elimination System (NPDES) permit program governing stormwater. As part of this enrollment, the City is required to implement the Central Coast RWQCB’s adopted Post- Construction Stormwater Management requirements through the development review process. The primary objective of these PCRs is to ensure that the permittee is reducing pollutant discharges to the maximum extent practicable and preventing Page 109 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 44 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 stormwater discharges from causing or contributing to a violation of receiving water quality standards in all applicable development projects that require approvals and/or permits. The 100-year flood zone identifies areas that would be subject to inundation in a 100-year storm event, or a storm with a 1% chance of occurring in any given year. Based on the City’s interactive Parcel Viewer and Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) map (06079C1066G, effective 11/16/2012), the project site is located within an area of minimal flooding and the onsite creek is not a 100-year flood zone hazard. There is an unnamed creek (identified as Twin Ridge Creek) with associated freshwater forested/shrub wetland and riparian areas located in the western portion of the project area. Project improvements propose a 20-foot setback from the riparian edge of the existing vegetation that would reduce impacts during future development and operation. Proposed project construction requires 4.27 acres of ground disturbance including 7,900 cy of cut and 4,760 cy of fill, which has the potential to release erosive runoff into the creek and associated wetland areas that may cause adverse effects to water quality. Parcel improvements require the use of construction vehicles and equipment that could lead to inadvertent polluted runoff through vehicle leakage or spill. The project proposes to disturb more than 1 acre of soil and would require the development and implementation of a SWPPP with BMPs to avoid or reduce erosive or polluted runoff from entering the onsite creek and associated wetland area. Section 4, Biological Resources, identifies Mitigation Measure BIO-9, which outlines BMPs that would reduce construction impacts related to polluted or erosive runoff. Project development would be required to comply with the Central Coast RWQCB requirements set forth in the Post-Construction Stormwater Management Requirements for Development Projects in the Central Coast Region. Future development as a result of the subdivision would include single-family residential uses, with ADUs and JADUs as potential accessory uses, potential removal of existing trees, and connections to the proposed utility lines. Grading activity for future development is proposed for current parcel improvements; therefore, it is unlikely that future development would require more than 1 acre of groundwork and would not likely need to develop and implement a SWPPP. However, future development would be required to comply with the Central Coast RWQCB PCRs, and physical improvement of the project site would be required to comply with the drainage requirements of the City’s Waterways Management Plan. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. Therefore, with implementation of Mitigation Measure BIO-9 during parcel improvements and compliance with existing regulations, impacts related to violation of water quality standards would be less than significant with mitigation. San Luis Obispo is located within the San Luis Obispo Valley Groundwater Basin. The Sustainable Groundwater Management Act (SGMA) requires that high- and medium-priority basins comply with the provisions of the SGMA. The California Department of Water Resources (DWR) designated the San Luis Obispo Valley Groundwater Basin as a high-priority basin, and the City has developed a Groundwater Sustainability Plan to comply with SGMA regulations. The COSE states the urban water planning and usage will use the “most efficient available practices” for water conservation. The “most efficient available practices” refer to behavior and devices that use the least water for a desired outcome, considering available equipment, lifecycle costs, social and environmental side effects, and the regulations of other agencies. Construction of the proposed project and future residential development would result in new development on previously undeveloped land and would result in an increase of impervious surfaces. Physical improvement of the project site would be required to comply with the drainage requirements of the City’s Waterways Management Plan. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. The Waterways Management Plan and Low Impact Development (LID) stormwater treatment requires that site development be designed so that post-development site drainage does not significantly exceed pre-development run- off. In order to comply with these standards, the project proposes four drainage measures throughout the project site, which include an 85th percentile retention area, a 95th percentile retention area, and Filterra and Biofiltration treatment. The proposed drainage measures would be implemented to catch additional surface runoff generated from the project during operation. The project is also required to comply with Post-Construction Stormwater Management Requirements, including requirements for site design, water quality treatment, runoff retention, and peak discharge management. These requirements include, and are not limited to, minimizing impervious surfaces, collecting stormwater runoff to reduce pollutant discharge, and maintaining the pre-developed hydrology by Page 110 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 45 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 reducing overland flow and promoting groundwater recharge. Therefore, based on compliance with existing regulations, implementation of the project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin. Based on the 2020 Water Resources Status Report, the City utilizes multiple water sources to meet its water supply needs. The four primary water sources for the City includes Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water; groundwater acts as the City’s fifth supplemental source. The total water available for the City in 2019 was 10,107 acre-feet per year (AFY). As this availability was adjusted following years of drought and updates to the City’s safe annual yield model, the availability is considered a reasonable long-term safe yield value for the purposes of this analysis. The 2020 Water Year (October 1, 2019 to September 30, 2020) had a total water demand of 4,762 AF with 0% of water being supplied by groundwater resources. Compared against the City’s 2019 annual availability, the City has approximately 5,374 AF of water surplus available to allocate to new beneficial uses within the city. The project would be required to pay development impact fees to offset the project’s marginal impact on the City’s water resources. Future residential development will be conditioned to comply with City standards, and potential impacts would be less than significant. c.i) Project construction requires 4.27 acres of grading activity, which includes 7,900 cy of cut and 4,760 cy of fill. The project does not propose alteration of the onsite creek; however, the BRA identified that several areas of grading are proposed within the creek setback and a rip rap pad at the stormwater retention area is planned adjacent to or within the creek setback area. Additionally, 13 non-native trees would be removed from the riparian corridor. The project proposes a 20-foot setback from the creek during proposed improvements. However, due to the amount of ground disturbance proposed for parcel improvements, there is potential for construction activity and permanent impervious surfaces associated with future development to temporarily alter onsite drainage patterns and disturb the creek channel, which could increase runoff on- or offsite. The project would be required to prepare and implement a SWPPP with BMPs designed to reduce erosive runoff to surface and other water resources in the area. Mitigation Measure BIO-9 identifies BMPs that would reduce erosive runoff during project construction. These BMPs include, and are not limited to, avoiding construction during the rainy season if feasible, preparation of a Sediment and Erosion Control Plan that would be reviewed and approved by the City Engineer, identification of construction staging areas (in locations that would not drain into the creek), and application of measures that are typically applied and approved by the City and resource agencies including the RWQCB and CDFW to protect water quality including silt fencing, erosion control blankets, straw bales, sandbags, fiber rolls, and/or other types of materials. Mitigation Measure BIO-10 requires that the applicant comply with existing RWQCB and CDFW regulations, permits, and authorization requirements, and has been clarified to require a biological monitor during construction activities and work within and adjacent to the riparian corridor regardless of whether regulatory permits are required, and the on-site monitor would ensure compliance with all local and state water quality regulations. Verification of the BMPs and Erosion and Sedimentation Control Plan and compliance with water quality regulations would occur during review of these standard plans by City and regulatory agency professionals and experts, and during installation of creek protection measures and any work within and adjacent to the creek by a biological monitor. The project would also be required to comply with Central Coast RWQCB requirements set forth in the Post-Construction Stormwater Management Requirements for Development Projects in the Central Coast Region. The 20-foot setback established during parcel improvements would ensure that future development would not require work within the onsite stream or associated wetland area. Grading activity for future development is proposed for current parcel improvements; therefore, it is unlikely that future projects would require more than 1 acre of groundwork; therefore, future development is not likely to substantially alter any existing drainage patterns that would lead to on- or offsite erosion. Because future development is not anticipated to disturb more than 1 acre of soils, the preparation and implementation of a SWPPP is not necessary. However, future development would be required to comply with the Central Coast RWQCB PCRs, and physical improvement of the project site would be required to comply with the drainage requirements of the City’s Waterways Management Plan. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. With implementation of BIO-9 and compliance with existing regulations, impacts related to erosion and siltation on- or offsite would be less than significant with mitigation. Page 111 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 46 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 c.ii–iv) As described in the evaluation above, the project site is not located within a flood zone. However, the proposed parcel improvements and future development would result in new impervious surface areas that could increase surface water runoff. Proposed parcel improvements would create a new interior road that loops from Stanford Drive to Cuesta Drive ranging from 54 to 60 feet in width, a 17-foot-wide AC bicycle/pedestrian pathway that would also be used as a utility and drainage easement across Lot 15, and other proposed access and easements. Future development plans are currently unknown; however, it is anticipated that single-family residential uses, with ADUs and JADUs as potential accessory uses, could be developed as a result of the subdivision, which would create more impervious surface areas. Construction of the proposed project and future residential development would result in new development on previously undeveloped land and would result in an increase of impervious surfaces that would cause the timing and amount of surface water runoff to increase. Physical improvement of the project site would be required to comply with the drainage requirements of the City’s Waterways Management Plan, which includes the Drainage Design Manual. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. The Waterways Management Plan and Low Impact Development (LID) stormwater treatment requires that site development be designed so that post-development site drainage does not significantly exceed pre-development run-off. The Drainage Design Manual states that “runoff shall be managed to prevent any significant increase in downstream peak flows, including 2-year, 10-year, 50-year, and 100-year events. Significant generally means an increase of over 5 percent at and immediately downstream of the project site, but must be determined on a site-specific basis” (DDM 3.3). In order to comply with these standards, the project proposes four drainage measures throughout the project site, which include an 85th percentile retention area, a 95th percentile retention area, and Filterra and Biofiltration treatment. The proposed drainage measures would be implemented to catch additional surface runoff generated from the project during operation. The proposed approach to peak flow management for this project at Twin Ridge Creek involves collecting a portion of the runoff from the proposed development, detaining that flow in a detention facility, and then introducing it to Twin Ridge Creek resulting in an overall reduction in peak flow for the system. At Cuesta, the runoff is collected and detained in an underground detention facility and then released onto the proposed site at Cuesta Drive. The proposed drainage at Stanford was designed so that the runoff would match existing drainage conditions (Cannon 2020). In addition, the project would be required to comply with the City’s engineering standards, water pollution control plan requirements, Post-Construction Stormwater Requirements, and adopted building and grading codes for water quantity/quality analysis. Compliance with these requirements would ensure operational impacts are less than significant and implementation of BIO-9 would reduce construction-related impacts to potential erosive runoff from alteration of drainage patterns; therefore, impacts would be less than significant with mitigation. d) The proposed project site is not located within a flood hazard, tsunami, or seiche zone; therefore, the release of pollutants due to project inundation is not anticipated, and no impacts would occur. e) The City’s COSE identifies goals and policies for the City’s water needs, including planning and water quality management. The proposed project and any future development would be conditioned to comply with the COSE water quality and groundwater management standards (Section 10). As discussed above, parcel improvements and future development would be compliant with the Central Coast RWQCB PCRs, the City’s Waterways Management Plan and LID design requirements, and other applicable water quality policies and regulations. The project would be required to pay development impact fees to offset the project’s marginal impact on the City’s water resources. Future residential development will be conditioned to comply with City standards, and potential impacts would be less than significant. Mitigation Measures Implement Mitigation Measure BIO-9. Conclusion The proposed project would be subject to City requirements regarding water quality and stormwater runoff. Future residential structures would be required to comply with the water quality and conservation standards stated in the COSE. The project is not located within a 100-year flood hazard, tsunami, or seiche zone. Therefore, project impacts on hydrology and water quality would be less than significant.

LAND USE AND PLANNING Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Physically divide an established community? 42 ☐ ☐ ☒ ☐ a) Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? 5, 42 ☐ ☒ ☐ ☐ Evaluation The project is zoned as R-1 (Low Density Residential) and located in the northern portion of the city. The surrounding land uses include one- and two-story single-family residential units to the south, east and west, undeveloped residential land to the north, and CAL FIRE Station #12 to the east. The proposed project is an infill project and would not have the potential to divide an established community on adjacent parcels or in the vicinity of the project site. The project is designed to be consistent with existing and developing/planned surrounding commercial infill development and would not physically divide an established community. Impacts would be less than significant. The project site is located within the city of San Luis Obispo and is subject to the City of San Luis Obispo General Plan. The project is zoned R-1 (Low Density Residential), and future residential development would be consistent with the zoning and required to follow design regulations for the zoning requirement (City Ordinances 17.16 and 17.70). Future development would be consistent with the COSE and other applicable regulations. Mitigation measures identified throughout this Initial Study would reduce environmental impacts that could conflict with existing regulations and ensure that future development would be consistent with applicable land use standards and regulations. Therefore, project impacts would be less that significant with mitigation. Mitigation Measures Implement mitigation measures identified in other sections of this Initial Study. Conclusion The proposed project would not divide an established community and identified mitigation measures would ensure future development is consistent with applicable land use plans. Therefore, no mitigation is necessary, and impacts to land use and planning would be less than significant. 12. MINERAL RESOURCES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? 5 ☐ ☐ ☐ ☒ b) Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? 5 ☐ ☐ ☐ ☒ Page 113 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 48 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Evaluation Mineral extraction is prohibited within city limits according to the COSE. a, b) No known mineral resources are present within the project site and future extraction of mineral resources is very unlikely due to the urbanized nature of the area and current restrictions on resource extraction within city limits; therefore, no impacts would occur. Mitigation Measures No mitigation is required. Conclusion According to the COSE, mineral extraction is prohibited within city limits. The project site is located within the city, and there would be no impact on mineral resources. 13. NOISE Would the project result in: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? 8, 43, 44, 45 ☐ ☒ ☐ ☐ b) Generation of excessive groundborne vibration or groundborne noise levels? 45 ☐ ☐ ☒ ☐ c) For a project located within the vicinity of a private airstrip or an airport land use plan, or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? 3 ☐ ☐ ☒ ☐ Evaluation As analyzed in the City’s 2014 LUCE Update EIR, a number of noise-sensitive land uses are present within the city, including various types of residential development, schools, hospitals and care facilities, parks and recreation areas, hotels and tran sient lodging, and places of worship and libraries. Based on ambient noise level measurements throughout the city, major sources of noise include traffic noise on major roadways, passing trains, and aircraft overflights. Per City Municipal Code Chapter 9.12, Noise Control, operating tools or equipment used in construction on weekdays between 7:00 p.m. and 7:00 a.m. or any time on Sundays or holidays is prohibited, except for emergency works of public service utilities or by exception issued by the City Community Development Department. The City Municipal Code also states that construction activities shall be conducted in such a manner, where technically and economically feasible, that the maximum noise levels at affected properties will not exceed 75 A-weighted decibels (dBA) at single-family residences, 80 dBA at multi-family residences, and 85 dBA at mixed residential/commercial uses. Based on the City Municipal Code (9.12.050.B.7), operating any device that creates vibration that is above the vibration perception threshold of an individual at or beyond 150 feet from the source if on a public space or right-of-way is prohibited. Typical noise levels produced by equipment commonly used for demolition and construction projects are shown in Table 3. Page 114 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 49 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Table 3. Construction Equipment Noise Emission Levels Equipment Type Typical Noise Level (dBA) 50 feet From Source Backhoe 80 Compactor 80 Concrete Mixer 85 Concrete Pump 82 Dozer 85 Excavator 85 Heavy Truck 84 Paver 85 Scraper 85 The nearest noise sensitive receptors to the project site include existing single-family residential units located adjacent to the site on the south, west, and east. Project construction has the potential to increase short-term noise in the surrounding area. Project construction includes demolition of two existing residential structures onsite, excavation and grading activity, development of a new connection road, and installation of utility infrastructure and easements. Parcel improvements would be required to adhere to City Municipal Code Section 22.10.120.A.4, which limits the hours and days of construction equipment use and seeks to limit construction noise to 85 dBA. Project construction would be conducted in close proximity to surrounding residential units. The nearest residential unit is located approximately 10 feet from the eastern property line. In addition, there are residential units to the west and south located within 10 to 15 feet from the property. Due to the close proximity of nearby residential uses, the proposed demolition and construction project activities have the potential to periodically exceed the City’s Municipal Code standard for conducting construction activities in such a manner that prevents noise levels above 75 dBa from reaching residential uses, when technically and economically feasible. Mitigation Measures N-1 and N-2 have been identified to reduce the potential for exceedances to occur and minimize potential temporary construction noise impacts to surrounding residential uses. Upon completion of construction activities, the project would not include any significant stationary noise sources and would not result in a substantial increase in vehicle noise that would result in an increase to the ambient noise environment. However, construction activity for future developments would create short-term noise and would be required to adhere to City Municipal Code Section 22.10.120.A.4 and other applicable regulations. In addition, future development would be required to implement Mitigation Measures N-1 and N-2 to mitigate noise from development activities near existing residential units. Operation of the project would be generally consistent with surrounding existing uses in the project vicinity and would not result in substantial changes to the existing noise environment. Therefore, upon implementation of Mitigation Measures N-1 and N-2, potential impacts associated with generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established would be less than significant with mitigation. The project does not propose pile driving or other high impact activities that would generate substantial groundborne noise or groundborne vibration during construction. Use of heavy equipment for excavation and other ground disturbance activity would generate groundborne noise and vibration, but these activities would be limited in duration and consistent with other standard construction activities and would likely not be substantial enough to be detected by occupants of surrounding land uses. Therefore, potential impacts would be less than significant. The project site is not located within the vicinity of a private airstrip or an airport land use plan; therefore, no impact would occur. Mitigation Measures Page 115 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 50 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 N-1 For the entire duration of the construction phase of the project, the following BMPs shall be adhered to: 1. Stationary construction equipment that generates noise that exceeds 60 dBA at the project boundaries shall be shielded with the most modern noise control devises (i.e., mufflers, lagging, and/or motor enclosures). 2. Impact tools (e.g., jack hammers, pavement breakers, rock drills, etc.) used for project construction shall be hydraulically or electrically powered wherever possible to avoid noise associated with compressed-air exhaust from pneumatically powered tools. 3. Where use of pneumatic tools is unavoidable, an exhaust muffler on the compressed air exhaust shall be used. 4. All construction equipment shall have the manufacturers’ recommended noise abatement methods installed, such as mufflers, engine enclosures, and engine vibration insulators, intact and operational. 5. All construction equipment shall undergo inspection at periodic intervals to ensure proper maintenance and presence of noise control devices (e.g., mufflers, shrouding, etc.). N-2 Construction plans shall note construction hours, truck routes, and all construction noise BMPs, and shall be reviewed and approved by the City Community Development Department prior to issuance of grading/building permits. The City shall provide and post signs stating these restrictions at construction entry sites prior to commencement of construction and maintained throughout the construction phase of the project. All construction workers shall be briefed at a preconstruction meeting on construction hour limitations and how, why, and where BMP measures are to be implemented. Conclusion The project has the potential to periodically exceed City Municipal Code construction and operational noise standards for single- family residential uses. With implementation of Mitigation Measures N-1 and N-2, potential impacts associated with temporary exceedances of local established standards would be less than significant. No other potentially significant impacts associated with noise were identified, and no additional mitigation measures are necessary. 14. POPULATION AND HOUSING Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? 46 ☐ ☐ ☒ ☐ b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? 1 ☐ ☐ ☒ ☐ Evaluation The city of San Luis Obispo is the largest city in terms of population in San Luis Obispo County and has grown from 45,119 in 2010 to approximately 48,826 in 2020, according to the City of San Luis Obispo General Plan Annual Report 2020 The City’s housing tenure is approximately 39% owner-occupied and 61% renter-occupied, which is strongly influenced by California Polytechnic State University, San Luis Obispo (Cal Poly) and Cuesta College enrollment. Many segments of the city’s population have difficulty finding affordable housing within the city due to their economic, physical, or sociological circumstances. San Luis Obispo contains the largest concentration of jobs in the county and, during workdays, the city’s population increases to an estimated 70,000 persons. Page 116 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 51 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The City of San Luis Obispo General Plan Housing Element identifies various goals, policies, and programs based on an assessment of the housing needs, opportunities, and constraints. The City’s overarching goals for housing include ensuring safety and affordability, conserving existing housing, accommodating for mixed-income neighborhoods, providing housing variety and tenure, planning for new housing, maintaining neighborhood quality, providing special needs housing, encouraging sustainable housing and neighborhood design, maximizing affordable housing opportunities for those who live or work in the city, and developing housing on suitable sites. The project site is zoned as R-1 (Low Density Residential). The project proposes a subdivision of one existing parcel into 23 different parcels, which would have the potential to support single-family residential uses, with ADUs and JADUs as potential accessory uses. Current proposed parcel improvements would not create structures that would cause population growth. The proposed construction is consistent with the General Plan, would improve the City’s jobs-housing balance, and would not create substantial unplanned population growth. Therefore, impacts to significant population growth would be considered less than significant. The project proposes demolition of the two existing residential units onsite. However, implementation of the project would create 23 new parcels that will be developed with single-family residential uses, with ADUs and JADUs as potential accessory uses. Therefore impacts would be less than significant. Mitigation Measures No mitigation is required. Conclusion The proposed parcel improvements and future development would not substantially increase population growth in the area, nor would it displace substantial numbers of people or existing housing. Future residential development would be consistent with the R-1 zone and the City’s General Plan, and potential impacts to population and housing would be less than significant. 15. PUBLIC SERVICES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: Fire protection? 1, 2, 47, 48 ☐ ☐ ☒ ☐ Police protection? 1, 2, 47, 48 ☐ ☐ ☒ ☐ Schools? 1, 2, 47, 48 ☐ ☐ ☒ ☐ Parks? 1, 2, 47, 48, 49 ☐ ☐ ☒ ☐ Other public facilities? 1, 2, 47, 48 ☐ ☐ ☒ ☐ Evaluation Page 117 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 52 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The project is located in the western portion of the city, 1.5 miles from the city’s downtown. The City of San Luis Obispo Fire Department (SLOFD) provides emergency response services for the city, including fire and medical, and is comprised of 57 full- time employees. The SLOFD operates out of four fire stations in the city, with the nearest station to the project located at City Fire Station #2, 126 North Chorro Street, near the intersection with Foothill Boulevard. The City of San Luis Obispo Police Department (SLOPD) provides public safety services for the city and is comprised of 85.5 employees, 59 of which are sworn police officers. The SLOPD operates out of one main police station, which is located at 1042 Walnut Street at the intersection of Santa Rosa Street (Highway 1) and US 101. The project site is located within the San Luis Coastal Unified School District (SLCUSD) and public parks and recreation trails within the city are managed and maintained by the City Department of Parks and Recreation. All new residential and nonresidential development within the city is subject to payment of development impact fees, which are administered by and paid through the City Community Development Department. Development impact fees provide funding for maintaining city emergency services, infrastructure, and facilities. For example, fire protection impact fees provide funding for projects such as the renovation of the City’s fire stations and the replacement of fire service vehicles and equipment. Fire protection: The project is located within a low fire severity zone and is under local fire jurisdiction. Fire response times to the project site are less than 5 minutes and the nearest fire station is City Fire Station #2, located 0.56 mile away. The project would result in single-family residential uses, with ADUs and JADUs as potential accessory uses and would not lead to a substantial increase in population in the city. Implementation of the project would not result in the need for construction of new or expanded fire protection facilities. In addition, the project would be subject to development fees for fire protection, which would offset the emergency access, upgraded roads, and necessary utility connections; therefore, potential impacts would be less than significant. Police protection: The SLOPD is located 1.4 miles southeast of the project site on Walnut Street. The project proposes uses generally consistent with the surrounding area, and the proposed level of development would be similar to surrounding residential development. The project proposes residential infill development and would not result in a substantial increase in demand on police protection services. The project would result in a slight increase in residents within the city and would be consistent with the projected population growth for the city. The project would not result in a substantial increase in the number of units or population in the city and would not result in the need for construction of new or expanded police protection facilities. The project would be required to pay development impact fees established to address direct demand for new facilities associated with new development. Therefore, the project impacts on police protection would be less than significant. Schools: The project site is located within the SLCUSD and would be subject to payment of SLCUSD development fees to offset the potential increase in student attendance in the district’s schools as a result of the project. These fees would be directed towards maintaining sufficient service levels, which include incremental increases in school capacities. The nearest schools are Bishop Peak Elementary School and Pacheco Elementary School, located less than 1 mile southeast and south of the project site, respectively. San Luis Obispo High School is located 2 miles away. Local schools have the capacity to support additional students that may cumulate from future residential development plans. Therefore, the project impacts on schools would be less than significant. Parks: The Patricia Drive entrance to the Bishop Peak Trailhead is located 0.5 mile northwest and Throop Park is 0.4 mile south of the project site. Future development plans for the project site have the potential to facilitate population growth and slightly increase demand on local parks. The General Plan outlines the importance of public recreation. The project does not currently propose the development of public parks; however, future population growth induced by future residential development would be supported by current facilities. The project would be subject to required developer impact fees (Quimby fees) established to address direct demand for new facilities associated with new development. Therefore, project impacts on parks would be less than significant. Other public facilities: The project would not induce substantial population growth and would result in a negligible effect on use of other public facilities, such as roadways and public libraries. The project would be subject to the City’s standard development fees, which would offset the project’s marginal contribution to increased use of City facilities. Therefore, potential project impacts on public facilities would be less than significant. Mitigation Measures Page 118 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 53 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 No mitigation is required. Conclusion The project site has the potential to induce future population growth of a maximum of 23 residential lots, which would be developed with residential units, consistent with the General Plan. There would not be substantial population growth and City development fees would offset the increased demand on any necessary public services. Therefore, project impacts on public services would be less than significant. 16. RECREATION Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? 48, 49 ☐ ☐ ☒ ☐ b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? 48, 49 ☐ ☐ ☐ ☒ Evaluation Existing City recreational facilities consist of 28 parks and recreational facilities, 10 designated natural resources and open space areas, and two bike trails. The City of San Luis Obispo General Plan Parks and Recreation Element identifies goals, policies, and programs to help plan, develop, and maintain community parks and recreation facilities. The City’s statement of overall department goals is for the City Parks and Recreation facilities and programs to enable all citizens to participate in fun, healthful, or enriching activities that enhance the quality of life in the community. As demand for recreation facilities and activities grow and change, the City intends to focus its efforts in the following ar eas: continuing development of athletic fields and support facilities, providing parks in underserved neighborhoods, providing a multi-use community center and therapy pool, expanding paths and trails for recreational use, linking recreation facilities, and meeting the special needs of disabled persons, at-risk youth, and senior citizens. Parks and Recreation Element Policy 3.13.1 establishes the City’s goal to develop and maintain a park system at the rate of 10 acres of parkland per 1,000 residents, 5 acres of which shall be dedicated as neighborhood parks. The Patricia Drive entrance to the Bishop Peak Trailhead is located approximately 0.5 mile northwest and Throop Park is 0.4 mile south of the project site. Future plans for the project site have the potential to facilitate population growth and increase demand on local parks. As discussed above, the project would be subject to required development impact fees established to address direct demand for new facilities associated with new development. Therefore, project impacts on parks would be less than significant. The project does not propose the development of recreational facilities, and possible future development includes residential development on the 23 residential lots, which would not require the construction or expansion of existing recreational facilities. Therefore, no impacts would occur. Mitigation Measures No mitigation is required. Conclusion Page 119 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 54 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The project site has the potential to induce future population growth of a maximum 23 residential lots, which would be developed with residential units, consistent with the General Plan. There would not be substantial population growth and City development fees would offset the increased demand on any necessary recreational facilities. Therefore, project impacts on recreation would be less than significant. 17. TRANSPORTATION Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? 1, 15, 21, 50 ☐ ☐ ☒ ☐ b) Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? 1, 50, 55 ☐ ☐ ☒ ☐ c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g. farm equipment)? 1, 50 ☐ ☐ ☒ ☐ d) Result in inadequate emergency access? 1, 50, 54 ☐ ☐ ☒ ☐ Evaluation The City of San Luis Obispo General Plan Circulation Element identifies current traffic levels and delays on public roadways, as well as transportation goals and policies to guide development and express the community’s preferences for current and future conditions. Goals included in the plan include, but are not limited to, maintaining accessibility and protecting the environment throughout San Luis Obispo while reducing dependence on single-occupant use of motor vehicles; reducing use of cars by supporting and promoting alternatives such as walking, riding buses and bicycles, and carpooling; promoting the safe operation of all modes of transportation; and widening and extending streets only when there is a demonstrated need and when the projects would cause no significant, long-term environmental problems. Level of Service (LOS) is a term used to describe the operating conditions of an intersection or roadway based on factors such as speed, travel time, queuing time, and safety. LOS designations range between A and F, with A representing the best operating conditions and F the worst. The Circulation Element establishes the minimum acceptable LOS standard for vehicles in the city as LOS D (except in downtown areas). The City of San Luis Obispo Active Transportation Plan outlines the City’s official policies for the design and development of infrastructure to support sustainable transportation within the city and in adjoining territory under County of San Luis Obispo jurisdiction but within the City’s Urban Reserve and includes specific objectives for reducing vehicle use and promoting other modes. In 2013 SB 743 was signed into law with the intent to “more appropriately balance the needs of congestion management with statewide goals related to infill development, promotion of public health through active transportation, and reduction of greenhouse gas emissions.” SB 743 required the Governor’s Office of Planning and Research (OPR) to identify new metrics for identifying and mitigating transportation impacts under CEQA. As a result, in December 2018, the California Natural Resources Agency certified and adopted updates to the State CEQA Guidelines. The revisions included new requirements related to the implementation of SB 743 and identified VMT per capita, VMT per employee, and net VMT as new metrics for transportation analysis under CEQA (as detailed in State CEQA Guidelines Section 15064.3(b)). Beginning July 1, 2020, the newly adopted VMT criteria for determining significance of transportation impacts must be implemented statewide. SLO Transit operates transit service within the city of San Luis Obispo and San Luis Obispo Regional Transit Auth ority (SLORTA) operates transit service throughout San Luis Obispo County and adjacent areas. The project site is located off Page 120 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 55 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Westmont Avenue from the east and Stanford Drive to the southwest. The project site is approximately 0.08 mile west of Santa Rosa Street between Foothill Boulevard and the northern City limits. The nearest bus stop is located 0.2 mile away at Highland Drive and Cuesta Drive. Additional bus stops are located 0.5 mile south along Foothill Boulevard. In June 2020, the City formally adopted the transition from LOS to VMT for the purposes of CEQA evaluation and also established local VMT thresholds of significance. Potential CEQA impacts are based on the VMT analysis. The project site is accessed by Westmont Avenue and Stanford Drive, which are residential streets, and vehicular trips on these streets are generated by residents. The proposed project would be consistent with the City’s Circulation Element, which establishes goals and policies for the City’s circulation system, described in the evaluation above. Future development would have access to several transit stops less than 0.5 mile away. The project proposes a new 17-foot-wide AC bicycle/pedestrian easement to promote alternative modes of transportation to and from the site. The proposed project is located approximately 0.56 mile north of dining, grocery, and other commercial buildings that could be reached using alternate modes of transportation. New development would be consistent with goals and policies described in the City’s Circulation Element and impacts would be less than significant. The 2018 OPR SB 743 Technical Advisory on Evaluating Transportation Impacts in CEQA states that absent substantial evidence indicating that a project would generate a potentially significant level of VMT, or inconsistency with a Sustainable Communities Strategy (SCS) or general plan, projects that generate or attract fewer than 110 trips per day generally may be assumed to cause a less-than-significant transportation impact. According to the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition, a single-family residential unit generates 9.44 average daily trips (ADT). The project would create 23 new parcels that could result in the development of single- family residential uses, with an ADUs and JADUs as potential accessory uses. Operation of the project may create more than 110 trips per day; however, based on the City’s Residential VMT Screening Map, the project is located in an area of the city that would result in average VMT less than or equal to 85% of the regional average, meaning a project in this area would result in VMT generation below the City’s adopted thresholds. Therefore, future potential development of the project is not anticipated to generate VMT at a rate that is inconsistent with adopted plans and impacts would be less than significant. The project proposes the improvements that include a new 54- to 60-foot-wide interior road, emergency access, and various easements, including a bicycle/pedestrian easement. These potential roadway improvements would be designed and constructed in compliance with City Public Works Department standards to provide adequate vehicle and emergency vehicle access to all proposed parcels. The project would not substantially increase hazards due to a geometric design feature or incompatible uses or result in inadequate emergency access. Therefore, project impacts would be less than significant. As mentioned above, the project proposes the implementation of emergency vehicle access that would be with City Public Works Department standards. The emergency access easement is a proposed improvement as part of the parcel subdivision and would be completed prior to any potential residential development. Therefore, there would be adequate access for emergency services and project impacts would be less than significant. Mitigation Measures No mitigation is required. Conclusion Potential future infill development of residential uses at the project site would not result in a reduction in LOS on surrounding intersections and would be consistent with State CEQA Guidelines Section 15064.3(b) regarding VMT. Any future development at the project site would be required to meet City Public Works Department safety design standards and would maintain adequate emergency access. Therefore, no potentially significant impacts related to transportation would occur, and no mitigation measures are necessary.

TRIBAL CULTURAL RESOURCES Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, or cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)? 17, 18, 19, 59 ☐ ☐ ☒ ☐ b) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1? In applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe. 17, 18, 19, 59 ☐ ☒ ☐ ☐ Evaluation Approved in 2014, AB 52 added tribal cultural resources to the categories of resources that must be evaluated under CEQA. Tribal cultural resources are defined as either of the following: 1. Sites, features, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are either of the following: a. Included or determined to be eligible for inclusion in the CRHR; or b. Included in a local register of historical resources as defined in subdivision (k) of California PRC Section 5020.1. 2. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of California PRC Section 5024.1. In applying these criteria for the purposes of this paragraph, the lead agency shall consider the significance of the resource to a California Native American Tribe. Recognizing that tribes have expertise with regard to their tribal history and practices, AB 52 requires lead agencies to provide notice to tribes that are traditionally and culturally affiliated with the geographic area of a proposed project if they have requested notice of projects proposed within that area. If the tribe requests consultation within 30 days upon receipt of the notice, the lead agency must consult with the tribe regarding the potential for adverse impacts on tribal cultural resources as a result of a project. Consultation may include discussing the type of environmental review necessary, the presence and/or significance of tribal cultural resources, the level of significance of a project’s impacts on the tribal cultural resources, and available project alternatives and mitigation measures recommended by the tribe to avoid or lessen potential impacts on tribal cultural resources. The City has provided notice of the opportunity to consult with appropriate tribes per the requirements of AB 52 and received correspondence from Patti Dunton, Tribal Administrator of the Salinan Tribe of San Luis Obispo, Monterey, and San Benito Counties. The correspondence included a request to have all ground disturbing activities for the project monitored by a cultural resource specialist from their tribe. No other responses from California Native American tribes have been received as of the date of this document. a.i, ii.) As discussed in the evaluation above, the City received one response from the Salinan Tribe of San Luis Obispo, Monterey, and San Benito Counties in accordance with AB 52. The tribe requested that a cultural resource specialist from their tribe monitor all ground disturbing activities approved with the project. The request for onsite monitoring has been included as a mitigation measure with the project as TC-1. No additional consultation was requested from the Salinan Tribe of San Luis Obispo, Monterey, and San Benito Counties beyond this request. There have been no other responses from Native American tribes in accordance with AB 52 as of the date of this draft. Therefore, impacts associated with tribal resources would be less than significant with mitigation. Page 122 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 57 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Mitigation Measures CR-1 and CR-2 have been identified to address the potential for inadvertent discovery of cultural resources and require cultural resource awareness training and cessation of work area if a discovery is made until a qualified archaeologist can assess the significance of the find. Therefore, impacts related to a substantial adverse change in the significance of tribal cultural resource would be less than significant with mitigation. Mitigation Measures TC-1 Culturally Affiliated Native American Monitor. A representative from the Salinan Tribe shall be notified prior to any ground disturbing activities to provide for on-site monitoring. If cultural resources are encountered during subsurface earthwork activities, all ground disturbing activities within a 25-foot radius of the find shall cease and the City shall be notified immediately consistent with the requirements of Mitigation Measures CR-1 and CR-2. Implement Mitigation Measures CR-1 and CR-2. Conclusion With implementation of Mitigation Measures CR-1,CR-2, and TC-1, impacts to tribal cultural resources would be less than significant. 19. UTILITIES AND SERVICE SYSTEMS Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? 1 ☐ ☒ ☐ ☐ a) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry, and multiple dry years? 39, 51 ☐ ☐ ☒ ☐ b) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? 47, 60 ☐ ☐ ☒ ☐ c) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? 52, 53 ☐ ☐ ☒ ☐ d) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste? 52, 53 ☐ ☐ ☒ ☐ Evaluation The City Utilities Department is the sole water provider within the city, provides potable and recycled water to the community, and is responsible for water supply, treatment, distribution, and resource planning. The City’s Water Resource Recovery Facility (WRRF) treats all wastewater from the city, Cal Poly, and the San Luis Obispo County Regional Airport, which includes 4.5 million gallons of wastewater per day. The WRRF manages and treats wastewater in accordance with standards established by the SWRCB to remove solids, reduce the amount of nutrients, and eliminate bacteria in treated wastewater. A portion of the treated water is recycled for irrigation use within the city and the remaining flow is discharged to San Luis Obispo Creek. Page 123 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 58 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The City utilizes San Luis Garbage as a licensed waste hauler for residential and commercial solid waste removal. Solid waste collected from the city is taken to Cold Canyon Landfill, which is a modern municipal solid waste disposal facility that is permitted by California Department of Resources, Recycling, and Recovery (CalRecycle) and meets state and local rules and regulations. The landfill disposes of non-hazardous solid waste. For water needs, parcel improvements propose connecting to the existing water line on Stanford Drive and looping it around to Cuesta Drive and a connection from Westmont Avenue will connect to Cuesta Drive through a proposed 17 foot-wide- easement of Lot 15. For sewer needs, parcel improvements propose connecting to the existing sewerline on Stanford Drive and also proposes an additional line connecting to Cuesta Drive. Lots 17 and 18 would use the existing sewer main on Westmont Avenue. The project proposes easements throughout the project site for additional utility connections and relocation of existing ones. Parcel improvements propose PG&E easements for electricity needs. Proposed drainage easements would occur across Lots 4, 15, and 19–23. Proposed drainage measures for the project include an 85th percentile retention area, a 95th percentile retention area, and Filterra and Biofiltration treatment system to capture surface runoff produced during project operation. Future development would require individual connections to the proposed utility lines. These new utility components and associated easements would have the potential to result in noise and dust emissions in proximity to sensitive receptor locations, such as single-family residences. There would also be the potential for discovery of subsurface cultural resources during proposed utility work. Excavation and other ground-disturbing activity has the potential to release erosive or pollutant runoff to the onsite creek and associated wetland area. Mitigation Measures AQ-1 through AQ-5, BIO-1 through BIO-9, CR-1 and CR-2, N-1 and N-2, and TC_1 would reduce potentially significant environmental impacts resulting from installation and establishment of new utility connections associated with air quality, biological resources, cultural resources, and noise, respectively, to less than significant. Therefore, potential environmental impacts associated with construction or extension of existing utilities would be less than significant with mitigation. The project would be serviced by the City’s water system, which has four primary water sources, including the Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water (for irrigation), with groundwater serving as a fifth supplemental source. As of 2015, the City no longer draws groundwater for potable purposes. The project is not within the City’s Recycled Water Master Plan Area and therefore recycled water is not available for irrigation use. As of November 2019, both the Salinas and Whale Rock Reservoirs are above 85% storage capacity and Nacimiento Reservoir is at 45% storage capacity. San Luis Obispo is located within the San Luis Obispo Valley Groundwater Basin. The SGMA requires that high- and medium-priority basins comply with the new law; the DWR designated the San Luis Obispo Valley Groundwater Basin as a high-priority basin. The City has developed a Groundwater Sustainability Plan to comply with SGMA regulations. The COSE states the urban water planning and usage will use the “most efficient available practices” for water conservation. The “most efficient available practices” refer to behavior and devices that use the least water for a desired outcome, considering available equipment, lifecycle costs, social and environmental side effects, and the regulations of other agencies. Based on the 2020 Water Resources Status Report, the City utilizes multiple water sources to meet its water supply needs. The four primary water sources for the City includes Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water; groundwater acts as the City’s fifth supplemental source. The total water available for the City in 2020 was 10,107 AFY. As this availability was adjusted following years of drought and updates to the City’s safe annual yield model, the availability is considered a reasonable long-term safe yield value for the purposes of this analysis. The 2020 Water Year (October 1, 2019 to September 30, 2020) had a total water demand of 4,730 AF with 0% of water being supplied by groundwater resources. Compared against the City’s 2020 annual availability, the City has approximately 5,377 AF of water surplus available to allocate to new beneficial uses within the city. The project would be required to pay development impact fees to offset the project’s marginal impact on the City’s water resources. Future residential development will be conditioned to comply with City standards, and potential impacts would be less than significant. The proposed project would create new parcels that range from 6,000 to 24,000 sf each. According to the City’s Wastewater Generation Rates per Use Table, residential units have to potential to generate 45 to 150 gallons of Page 124 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 59 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 wastewater per day based on size of the dwelling unit. Specific development plans have not been identified; however, there is potential for up to 23 new single-family residential units, with ADUs and JADUs as potential accessory uses, to result from the proposed project. According to the City’s wastewater generation rates, a typical single-family residence would generate approximately 150 gallons of wastewater per day and an ADU would generate approximately 105 gallons of wastewater per day. (JADUs are connected to single-family residences and are included with that rate.) The project has the potential to generate approximately 5,865 gallons of wastewater per day. The City treats about 4.5 million gallons of wastewater per day according to standards set forth by the SWRCB. The WRRF operates in an efficient manner to comply with federal, State, and local discharge requirements. This additional wastewater generation would not result in a significant load on the City’s sewer infrastructure or the WRRF. Additionally, impact fees are collected at the time building permits are issued to accommodate the project’s contribution to the City’s WRRF capacity. Therefore, potential impacts would be less than significant. Grading and other ground-disturbing activity has the potential to temporarily increase solid waste generation. Soil and other waste that results from ground-disturbing activity would be disposed of according to applicable standards and would not lead to the generation of excessive waste. The proposed project has the potential to create up to 23 new single-family residential units, with ADUs and JADUs as potential accessory uses, that would produce solid waste. According to the CalRecycle Estimated Solid Waste Generation Rates Table, residential units generate approximately 12.23 pounds of solid waste per day. CalRecycle does not include specific rates for ADUs; however, it can be assumed that based on the size of ADUs as compared to single- family residential units, that ADUs produce solid waste at rates more similar to multi-family dwellings, which produce approximately 4 pounds per day. (JADUs are connected to single-family residences and are included with that rate.) Therefore, the project would produce approximately 373.29 pounds of solid waste per day. Future residential development would include provision of solid waste and recycling receptacles that would be serviced by San Luis Garbage and brought to Cold Canyon Landfill, which has approximately 13,100,000 cubic yards of remaining capacity as of February 2020 and is expected to reach capacity in 2040. Cold Canyon Landfill is compliant with State and local rules and regulations regarding solid waste and potential future residential development would be required to adhere to the standards set forth in the City’s Development Standards for Solid Waste Services for trash, green waste, and recycling. Therefore, potential impacts would be less than significant. Solid waste is disposed of at Cold Canyon Landfill, which follows State and local rules and regulations regarding solid waste. The potential future residential development would be required to adhere to the standards set forth in the City’s Development Standards for Solid Waste Services for trash, green waste, and recycling. Therefore, the impacts would be less than significant. Mitigation Measures Implement Mitigation Measures AQ-1 through AQ-5, BIO-1 through BIO-9, CR-1 and CR-2, N-1 and N-2, and TC-1. Conclusion With implementation of Mitigation Measures AQ-1 through AQ-5, BIO-1 through BIO-9, CR-1 and CR-2, N-1 and N-2, and TC-1, potential impacts to utilities and service systems would be less than significant. 20. WILDFIRE If located in or near state responsibility areas or lands classified as very high fire hazard severity zones, would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Substantially impair an adopted emergency response plan or emergency evacuation plan? 25, 54 ☐ ☐ ☒ ☐ Page 125 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 60 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? 1, 25, 54, 56, 57 ☐ ☐ ☒ ☐ c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? 1, 25, 54, 56, 57 ☐ ☐ ☒ ☐ d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? 1, 25, 54, 56, 57 ☐ ☐ ☒ ☐ Evaluation Urban fire hazards result from the materials, size, and spacing of buildings, and from the materials, equipment, and activities they contain. Additional factors are access, available water volume and pressure, and response time for firefighters. Based on the City Local Hazard Mitigation Plan, the risk of wildland fires is greatest near the City limits where development meets rural areas of combustible vegetation. Most of the community is within 1 mile of a designated high or very high fire hazard severity zone, which indicates significant risk to wildland fire. The Safety Element identifies four policies to address the potential hazards associated with wildfire, including approving development only when adequate fire suppression services and facilities are available, classification of wildland fire hazard severity zones as prescribed by CAL FIRE, prohibition of new subdivisions located within “very high” wildland fire hazard severity zones, and continuation of enhancement of fire safety and construction codes for buildings. According to the City’s Safety Element Maps, the project is located within a low fire hazard severity zone. The project site is surrounded by developed residential areas to the east, north, west, and south that are also designated as a low fire hazard severity zone. The area of land located to the east north of the project is designated as a moderate fire hazard severity zone and Bishop Peak located 0.5-mile northwest is designated as a high fire hazard severity zone. In addition, the project site is not located within a State Responsibility Area (SRA). The project proposes infill development within an existing residential neighborhood. Implementation of the proposed project would not result in a significant temporary or permanent impact on any adopted emergency response plans or emergency evacuation plans. No breaks in utility service or road closures would occur as a result of project implementation; therefore, the project would not substantially impair an adopted emergency response plan or evacuation plan and impacts would be less than significant. The Safety Element describes the project area and immediate land as low and moderate wildland fire risk. The nearest high wildland fire risk is located 0.5 mile northwest at Bishop Peak. Fire response times are less than 5 minutes for this project location and City Fire Station #2 is located approximately 0.56 mile south of the project site. The General Plan states that development shall only be approved when adequate fire suppression services and facilities are available or will be made concurrent with development. Parcel upgrades include emergency access, upgraded roads, and necessary utility connections. San Luis Obispo has an average wind speed of approximately 7 miles per hour. The project site is located on land that is characterized as gently sloping and would not increase fire risk due to hazardous slopes onsite. Parcel improvements propose to remove multiple ornamental trees and vegetation from the project site that would reduce wildfire hazard. Future residential structures built on the upgraded parcels would be conditioned to comply with building and fire code regulations as well as City requirements for fire safety. In order to manage wildfire risk associated with placing residents in close proximity to moderate and high fire hazard severity areas, a Vegetation/Fuel Management Plan for the project site has been identified in Mitigation Measure WF-1. Additionally, a Wildland Fire Protection Report by James A. Neumann identifies mitigation measures to further reduce wildland fire hazards to future development and is described in Mitigation Measure WF-2. Therefore, with Page 126 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 61 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 implementation of Mitigation Measures WF-1 and WF-2, impacts would be considered less than significant with mitigation. The proposed improvements to the project site include a new emergency access road, road upgrades, and necessary utility connections. Additionally, future residential developments would also be required to comply with CBC regulations for fire safety and to reduce fire risk. Therefore, impacts would be less than significant. The project area is not located within an area with substantial risk for flooding or landslides. Improvements made to the project site for the proposed subdivision and future development of residential structures will be required to comply with CBC regulations for fire safety and stability. The project does not include any design elements that would expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. Therefore, impacts would be less than significant. Mitigation Measures WF-1 Vegetation/Fuel Management Plan. Prior to issuance of any construction permit, the applicant shall provide a vegetation/fuel management plan prepared by a registered professional forester or certified arborist for each lot. The plan shall identify fuel load reduction techniques, including vegetation removal and trimming, to increase defensible space around residential structures and driveways/access roads. The plan shall also identify appropriate standards for installation of new landscaping, such as requirements for drought-tolerant and fire-resistant species. WF-2 Additional Fire Hazard Reductions. Future development would incorporate the following fire reduction methods identified by the 2020 Wildland Fire Protection Report (Neumann) to reduce wildland fire risk: 1. Rain gutters, when not adequately maintained, will collect leaf material which becomes a receptive fuel bed for embers and sparks and can then transmit fire underneath the non-combustible roof materials. Rain gutters should be protected by noncombustible leaf shields or not allowed. 2. Record on all lots a deed restriction that allows for only non-combustible fences and decks in the subdivision. 3. Record on all lots a deed restriction that allows for fire resistant landscaping in the back yards of the subdivision. 4. Require enclosed eves on all structures within the subdivision. 5. Install fireproof vents on all structures (fire-rated, flame and ember resistant). 6. Working with the biologist, remove the non-native vegetation in the creek, riparian area, to reduce the fuel load. 7. Install a non-combustible wall (block or steel stud /stucco) wall 36 inches in height all around the northern perimeter of the subdivision. The wall shall begin at the westernmost property line and continue to the 20- foot setback at the west side of the creek, and shall continue beginning at the 20-foot setback at the east side of the creek, terminating at the property line of CAL FIRE Station #12. The purpose of this wall is to interrupt fire progression from the north onto the proposed lots without obstructing the very desirable view of the open space. Conclusion The project is located 0.5 mile away from a high wildland fire hazard zone and could expose people or structures to new or exacerbated wildfire risks. The development of new and/or expanded infrastructure and maintenance to reduce wildfire risks is proposed along with parcel improvements to the project site. Mitigation Measures WF-1 and WF-2 would reduce wildland fire risk. Therefore, potential impacts associated with wildfire would be less than significant with mitigation.

MANDATORY FINDINGS OF SIGNIFICANCE Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? N/A ☐ ☒ ☐ ☐ The project would allow for the future development of up to 23 new residential units with ADUs and JADUs as accessory uses within the project site and would result in the removal of several trees. Mitigation measures BIO-1 through BIO-7 identified in Section 4, Biological Resources, are included to minimize potential impacts to native plants and wildlife species during project construction. Specifically, Mitigation Measure BIO-8 through BIO-11 would reduce impacts to aquatic resources onsite. Mitigation Measures CR-1 and CR-2 have been included to require awareness training be conducted for all construction crew members so that cultural resources can be recognized if unearthed during site disturbance activities and to require work be halted in the event of an unanticipated discovery until a qualified archaeologist can assess the significance of the find and identify the appropriate protocol for properly responding to the inadvertent discovery. TC-1 requires a native American monitor to be present during ground disturbance to identify unknown tribal cultural resources. With implementation of the recommended mitigation measures, potential impacts would be less than significant with mitigation. Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? N/A ☐ ☒ ☐ ☐ When project impacts are considered along with, or in combination with, other reasonably foreseeable impacts, the project’s potential cumulative impacts may be significant. Mitigation measures have been incorporated into the project to reduce project- related impacts to a less-than-significant level. Based on implementation of identified project-specific mitigation measures and the relatively limited number and extent of potential impacts, the cumulative effects of the proposed project would not be cumulatively considerable and would be less than significant with mitigation. Page 128 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 63 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? N/A ☐ ☒ ☐ ☐ The project has the potential to result in significant impacts associated with air quality and noise that could result in sub stantial adverse effects on human beings. Mitigation Measures AQ-1 through AQ-5 and N-1 and N-2 have been identified to reduce these potential impacts to less than significant, including, but not limited to, standard idling restrictions, dust control measures, preparation of a geologic investigation for asbestos, and implementation of noise control measures. With implementation of the mitigation measures identified in this Initial Study, potential environmental effects of the project would not directly or indirectly result in any substantial adverse effects on human beings, and this impact would be less than significant with mitigation.

During all construction activities and use of diesel vehicles, the applicant shall implement the following idling control techniques: 1. Idling Restrictions Near Sensitive Receptors for Both On- and Off-Road Equipment. a. Staging and queuing areas shall not be located within 1,000 feet of sensitive receptors if feasible; b. Diesel idling within 1,000 feet of sensitive receptors shall not be permitted; c. Use of alternative-fueled equipment shall be used whenever possible; and d. Signs that specify the no idling requirements shall be posted and enforced at the construction site. 2. California Diesel Idling Regulations. On-road diesel vehicles shall comply with 13 CCR 2485. This regulation limits idling from diesel-fueled commercial motor vehicles with gross vehicular weight ratings of more than 10,000 pounds and licensed for operation on highways. It applies to California- and non-California-based vehicles. In general, the regulation specifies that drivers of said vehicles: a. Shall not idle the vehicle’s primary diesel engine for greater than 5 minutes at any location, except as noted in Subsection (d) of the regulation; and b. Shall not operate a diesel-fueled auxiliary power system (APS) to power a heater, air conditioner, or any ancillary equipment on that vehicle during sleeping or resting in a sleeper berth for greater than 5 minutes at any location when within 1,000 feet of a restricted area, except as noted in Subsection (d) of the regulation. Signs must be posted in the designated queuing areas and job sites to remind drivers of the 5-minute idling limit. The specific requirements and exceptions in the regulation can be reviewed at the following website: www.arb.ca.gov/msprog/truck-idling/2485.pdf. AQ-2 Particulate Matter Control Measures. During all construction and ground-disturbing activities, the applicant shall implement the following particulate matter control measures and detail each measure on the project grading and building plans: 1. Reduce the amount of disturbed area where possible. 2. Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site and from exceeding the SLOAPCD’s limit of 20% opacity for greater than 3 minutes in any 60- minute period. Increased watering frequency would be required whenever wind speeds exceed 15 miles per hour (mph). Reclaimed (non-potable) water should be used whenever possible. 3. All dirt stockpile areas (if any) shall be sprayed daily and covered with tarps or other dust barriers as needed. 4. Permanent dust control measures identified in the approved project revegetation and landscape plans shall be implemented as soon as possible, following completion of any soil-disturbing activities. 5. Exposed grounds that are planned to be reworked at dates greater than 1 month after initial grading shall be sown with a fast germinating, non-invasive, grass seed and watered until vegetation is established. 6. All disturbed soil areas not subject to revegetation shall be stabilized using approved chemical soil binders, jute netting, or other methods approved in advance by the SLOAPCD. 7. All roadways, driveways, sidewalks, etc. to be paved shall be completed as soon as possible. In addition, building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. Page 134 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 69 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 8. Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved surface at the construction site. 9. All trucks hauling dirt, sand, soil, or other loose materials are to be covered or shall maintain at least 2 feet of freeboard (minimum vertical distance between top of load and top of trailer) in accordance with California Vehicle Code (CVC) Section 23114. 10. “Track out” is defined as sand or soil that adheres to and/or agglomerates on the exterior surfaces of motor vehicles and/or equipment (including tires) that may then fall onto any highway or street as described in CVC Section 23113 and California Water Code (CWC) Section 13304. To prevent track out, designate access points and require all employees, subcontractors, and others to use them. Install and operate a “track-out prevention device” where vehicles enter and exit unpaved roads onto paved streets. The track-out prevention device can be any device or combination of devices that are effective at preventing track out, located at the point of intersection of an unpaved area and a paved road. Rumble strips or steel plate devices need periodic cleaning to be effective. If paved roadways accumulate tracked- out soils, the track-out prevention device may need to be modified. 11. Sweep streets at the end of each day if visible soil material is carried onto adjacent paved roads. Water sweepers shall be used with reclaimed water where feasible. Roads shall be pre-wetted prior to sweeping when feasible. 12. All PM10 mitigation measures required should be shown on grading and building plans. 13. The contractor or builder shall designate a person or persons whose responsibility is to ensure any fugitive dust emissions do not result in a nuisance and to enhance the implementation of the mitigation measures as necessary to minimize dust complaints and reduce visible emissions below the SLOAPCD’s limit of 20% opacity for greater than 3 minutes in any 60-minute period. Their duties shall include holidays and weekend periods when work may not be in progress (for example, wind-blown dust could be generated on an open dirt lot). The name and telephone number of such persons shall be provided to the SLOAPCD Compliance Division prior to the start of any grading, earthwork, or demolition (Contact Tim Fuhs at 805-781-5912). AQ-3 Geologic Evaluation. Prior to initiation of ground-disturbing activities, the applicant shall retain a registered geologist to conduct a geologic evaluation of the property, including sampling and testing for NOA in full compliance with SLOAPCD requirements and the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105). This geologic evaluation shall be submitted to the City Community Development Department upon completion. If the geologic evaluation determines that the project would not have the potential to disturb NOA, the applicant must file an Asbestos ATCM exemption request with the SLOAPCD. AQ-4 Naturally Occurring Asbestos Control Measures. If NOA are determined to be present onsite, proposed earthwork, demolition, and construction activities shall be conducted in full compliance with the various regulatory jurisdictions regarding NOA, including the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (17 CCR 93105) and requirements stipulated in the National Emission Standard for Hazardous Air Pollutants (NESHAP; 40 Code of Federal Regulations [CFR] Section 61, Subpart M – Asbestos). These requirements include, but are not limited to, the following: 1. Written notification, within at least 10 business days of activities commencing, to the SLOAPCD; 2. Preparation of an asbestos survey conducted by a Certified Asbestos Consultant; and 3. Implementation of applicable removal and disposal protocol and requirements for identified NOA. AQ-5 Asbestos-Containing Material. Prior to issuance of demolition permits, the applicant shall provide an asbestos report that was prepared by a certified asbestos consultant. If ACM are determined to be present, at least 10 working days prior to any demolition work the applicant shall provide notification to SLOAPCD of such work. The notification shall include an asbestos report that was prepared by a certified asbestos consultant. ACM removal and disposal shall follow the requirements of the National Emission Standards for Hazardous Air Pollutants Regulation (NESHAP) Subpart M and of the SLOAPCD. Page 135 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 70 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Monitoring Program: These measures shall be incorporated onto Final Map and project grading / building plans for review and approval by the City Community Development Department. Compliance shall be verified by the City during regular inspections, in coordination with the SLOAPCD, as necessary. Biological Resources BIO-1 Implement a Rare Plant Mitigation Program that ensures no net loss of Cambria morning glory on the project site. Prior to any tract improvements, a Rare Plant Mitigation Program shall be implemented for Cambria morning glory and shall be overseen by a qualified botanist approved by the City. As a component of the program, seed shall be collected from Cambria morning glory plants during the appropriate season prior to tract grading activities. Using standard procedures, the qualified botanist shall clean and store the seeds until the receiving sites shown on the project plans are ready. Suitable habitat of 2,180 square-feet in size outside of the development area (as designated on the site plans in the creek setback zone) shall be designated as the mitigation site that will be maintained in a natural state and not be subject to mowing earlier than June 1 each year. The areas will be maintained as grassland habitat and no planting of ornamental species or other adverse modifications (such as grazing activities) will be allowed. The mitigation site shown on the project plans is twice the size as the areas currently occupied by the rare plant occurrences (2,180 square-feet of habitat created for 1,076 square-feet of habitat impacted). This equates to a 2:1 mitigation ratio (habitat created to habitat impacted) to ensure a minimum 1:1 replacement ratio is achieved. Topsoil from each of the four occurrences will be collected in 6-inch lifts and stored for top-dressing the mitigation site once grading of the pads is complete. As needed, the mitigation site should be prepared for planting by removal of non-native species or other measures as necessary, then applying the salvaged topsoil. Once topsoil has been layered evenly through the area, collected seed should be hand- broadcasted into suitable locations by the qualified botanist and covered with compost. Seed may also be incorporated into the native erosion control seed mix described in the Native Erosion Control Seed Mix table under Mitigation Measure BIO-9 and applied to other grassy areas of the site as part of the erosion control effort. Depending on the season when construction starts, the qualified botanist may also potentially salvage plants (i.e., dig them up when soils are moist) and transplant them to containers to be maintained until the mitigation sites are ready for planting. BIO-2 Conduct annual monitoring and implement adaptive management measures for 5 years to ensure no net loss of Cambria morning glory onsite. The Rare Plant Mitigation Program shall include annual monitoring and maintenance of the mitigation site to ensure success of the program. Monitoring by a qualified botanist shall occur during the spring growing season (between April 15 and May 15 each year) to ensure successful establishment of planted propagules. The established rare plants shall be mapped to evaluate the goal of no net loss of the species onsite. The measurable objective shall be to have at least 1,076 sf of occurrence comprised of approximately 300 Cambria morning glory plants. Appropriate vegetation sampling techniques shall be used to assess the areal cover of vegetation to evaluate the status of the established occurrences. If the success criteria of having approximately 300 plants covering 1,076 sf within the creek setback zone is not reached by the third year of monitoring, remedial actions such as collecting more seed and distributing it in suitable areas should be employed, with a corresponding additional year of monitoring. Other activities to increase the success of the rare plant mitigation effort could include non-native plant species removal within the mitigation site to reduce competition, additional seed application, or supplemental irrigation during periods of prolonged drought. The qualified botanist shall prepare annual reports for the applicant detailing the methods and results of the mitigation effort and monitoring effort. The applicant shall be responsible for submitting the report to the City on an annual basis (by December 31 of each year) for the 5-year monitoring period or until the final success criteria described above are met. BIO-3 To the extent feasible, avoid initial site grading in the winter months. The burrowing owl has been recorded in the vicinity of the project from October to the end of April. If initial vegetation removal and site grading for the tract improvements is conducted outside of this period, potential effects on this species would be avoided and no further mitigation would be required. Restricting the time period for earth-moving activities is also required to avoid or minimize the potential for erosion and sedimentation (see Mitigation Measure BIO-9). If initial grading work must commence during the time period that burrowing owls may be present onsite, preconstruction surveys for this species shall be included in the survey effort described in Mitigation Measure BIO-4 prior to vegetation removal or tract improvements. Page 136 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 71 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 BIO-4 Conduct a preconstruction survey and avoid construction in areas occupied by special-status wildlife species until relocated or they have left the site. Within 7 days prior to the start of vegetation/tree removal, ground-disturbing activities, or demolition of existing structures, a biologist approved by the City shall survey the project impact area to identify whether nesting birds, roosting bats, monarch butterfly overwintering populations, obscure bumble bee, and/or California legless lizard are present on site. A separate survey shall be conducted for any phase of the project not conducted concurrently or within 10 days of cessation of the previous phase (i.e., structure demolition conducted prior to general site grading). The biologist shall use appropriate survey techniques for the special-status species identified in the 2020 BRA as having potential to occur onsite. For example, burrows shall be examined with binoculars or wildlife cameras, and inspected for whitewash or prey remains. Leaf litter and cover objects shall be searched for northern California legless lizards. Potential bat roost sites shall be inspected for sign of roosting bats such as guano or prey remains. If any of these species are found onsite, the biologist shall coordinate with the City, and CDFW as appropriate, on methods to ensure the successful relocation of individuals to suitable habitat nearby. In some cases, CDFW may recommend creating structures for displaced woodrats and bats. Burrowing owls can be discouraged from using burrows onsite, or occupied burrows can be avoided until the owls have left the area. Bats can be restricted from roost sites by placing netting over their entrances after they have left the roost for night-time foraging. The wildlife protection measures to be employed will be based on the results of the survey and the particular characteristics of their use of the site, in coordination with CDFW and the construction engineer. If no special-status animal species are found onsite during the preconstruction survey, work may proceed with the implementation of the following Mitigation Measures BIO-5 through BIO-7. BIO-5 Prepare and present a Worker Environmental Awareness Program. Prior to any vegetation removal or tract improvements, a qualified biologist shall prepare a Worker Environmental Awareness Program that will be presented to all project personnel. This program shall detail measures to avoid and minimize impacts on biological resources. It shall include a description of special-status species potentially occurring on the project site and their natural history, the status of the species and their protection under environmental laws and regulations, and the penalties for take. Recommendations shall be given as to actions to avoid take should a special-status species be found on the project site. Other aspects of the training shall include a description of general measures to protect wildlife, including: 4. Delineation of the allowable work area, staging areas, access points, and limits to vehicle access; 5. Storage of all pipes, metal tubing, or similar materials stored or stacked on the project site for one or more overnight periods shall be either securely capped before storage or thoroughly inspected for wildlife before the materials are moved, buried, capped, or otherwise used. 6. Inspection of materials stored onsite, such as lumber, plywood, and rolls of silt fence, for wildlife that may have sheltered under or within the materials; 7. Use of netting to exclude birds from nesting in construction materials; 8. Construction of escape ramps in all excavations and trenches more than 6 inches deep; 9. Contact information for the City-approved biologist and instructions should any wildlife species be detected in the work site; 10. Dust suppression methods during construction activities when necessary to meet air quality standards and protect biological resources; and 11. Methods for containment of food-related trash items (e.g., wrappers, cans, bottles, food scraps), small construction debris (e.g., nails, bits of metal and plastic), and other human generated debris (e.g., cigarette butts) in animal-proof containers and removal from the site on a weekly basis. All project personnel who have attended the training shall sign an attendance sheet. The program shall be repeated for any new crews that arrive subsequently on the site. BIO-6 Install high-visibility construction and silt fence along the creek corridor to delineate the allowable work area, exclude wildlife from the site, and protect the stream habitat. Prior to vegetation removal or tract improvements, and during subsequent residential development for Lots 1-7, a high-visibility construction fence at least 4 feet tall together with a silt fence, or an approved wildlife exclusion fence, shall be erected along the Page 137 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 72 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 creek corridor to delineate the limits of grading and vehicle access. If possible, the fence shall be erected along the creek setback line, and encroachment into the setback shall be kept at a minimum. In no case shall ground disturbance occur within the riparian habitat or below the top of bank without obtaining proper permits from regulatory agencies. The type of fence used may be a combination of wildlife exclusion and silt fence (i.e., ERTEC Triple-function E-fence) or similar materials that would serve the purposes of safety/construction area delineation, wildlife exclusion, and siltation prevention. The fence shall be checked weekly by construction personnel for needed maintenance. BIO-7 Conduct biological monitoring for special-status wildlife species while the property is cleared and graded, and structures are removed. A qualified biologist shall monitor the removal of structures, materials, and vegetation that may provide cover for obscure bumble bee, northern California legless lizards, and bat roosting sites. The biologist shall be onsite daily until all materials are removed and all vegetation has been cleared. If any special-status species are found, work shall be delayed until the individuals have left the work area or CDFW shall be notified to obtain authorization for capture and relocation. BIO-8 Avoid vegetation removal within the riparian habitat during the overwintering season. Vegetation removal within the riparian area shall be conducted outside of the overwintering season for monarch butterfly (late October through February) and obscure bumble bee (late October through January) to avoid disturbance to species potentially inhabiting riparian vegetation. BIO-9 Install erosion and sediment BMPs and revegetate graded areas. The following erosion and sedimentation control BMPs are required to be implemented during vegetation removal, tract improvements, during individual lot construction, and after the construction phases of the project: 12. If possible, the potential for erosion and sedimentation shall be minimized by scheduling construction to occur outside of the rainy season, which is typically defined as October 15 through April 15. Adherence to this measure would also serve as avoidance for the burrowing owl, as described in Mitigation Measure BIO-3. 13. To minimize site disturbance, all construction related equipment shall be restricted to established roads, construction areas, and other designated staging areas. The creek setback zone shall be clearly marked as described in Mitigation Measure BIO-6. 14. Prior to any site disturbance during tract improvements or individual lot construction, a Sediment and Erosion Control Plan shall be prepared by a qualified engineer. The use of silt fence, straw wattles, erosion control blankets, straw bales, sandbags, fiber rolls, and other appropriate techniques should be employed to protect the drainage features on and off the property. Biotechnical approaches using native vegetation shall be used as feasible. All areas with soil disturbance shall have appropriate erosion controls and other stormwater protection BMPs installed to prevent erosion potential. All sediment and erosion control measures shall be installed per the engineer’s requirements prior to the initiation of site grading if planned to occur within the rainy season. 15. Spill kits shall be maintained on the site, and a Spill Response Plan shall be in place. 16. No vehicles or equipment shall be refueled within 100 feet of wetland areas, riparian habitat and/or drainage features, and refueling areas shall have a spill containment system installed. No vehicles or construction equipment shall be stored overnight within 100 feet of these areas unless drip pans or ground covers are used. All equipment and vehicles shall be checked and maintained on a daily basis to ensure proper operation and to avoid potential leaks or spills. Construction staging areas shall be located in a location where spills would not drain into aquatic habitats. 17. No concrete washout shall be conducted on the site outside of an appropriate containment system. Washing of equipment, tools, etc. should not be allowed in any location where the tainted water could enter onsite drainages. 18. The use of chemicals, fuels, lubricants, or biocides shall be in compliance with all local, state, and federal regulations. All uses of such compounds shall observe label and other restrictions mandated by the U.S. Environmental Protection Agency, California Department of Food and Agriculture, and other state and federal legislation. Page 138 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 73 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 19. All project-related spills of hazardous materials within or adjacent to the project site should be cleaned up immediately. 20. All areas with soil disturbance shall have appropriate erosion controls and other stormwater protection BMPs installed to prevent erosion potential. Silt fencing, erosion control blankets, straw bales, sandbags, fiber rolls, and/or other types of materials prescribed on the plan shall be implemented to prevent erosion and sedimentation. Biotechnical approaches using native vegetation shall be used as feasible. 21. Areas with disturbed soils shall be restored under the direction of the project engineer in consultation with a qualified restoration ecologist as detailed above. Methods may include recontouring graded areas to blend in with existing natural contours, covering the areas with salvaged topsoil containing native seedbank from the site, and/or applying the native seed mix as described in the table below. Native seed mix shall be applied to the graded areas in the creek setback area through either direct hand seeding or hydroseeding methods. Seeding with the native erosion control seed mix should be provided on all disturbed soil areas prior to the onset of the rainy season (by October 15). Native Erosion Control Seed Mix Species Application Rate (lbs/acre) California Brome (Bromus carinatus) 10 purple needlegrass (Stipa pulchra) 5 tomcat clover (Trifolium wildenovii) 5 six weeks fescue (Vulpia microstachys) 5 Total 25 BIO-10 Obtain necessary permits for impacts in jurisdictional areas, implement a compensatory mitigation program, and monitor the success of the program to ensure no net loss of Riparian/Wetland habitat or other waters on the subject property. Prior to any vegetation removal or site disturbance within the areas delineated as jurisdictional features (Figure 5, Aquatic Resources Delineation 2021), the applicant shall provide documentation to the City that a Clean Water Act Section 404 Permit from USACE, a Clean Water Act Section 401 Water Quality Certification from RWQCB, and a California Fish and Game Code Section 1602 Lake and Streambed Alteration Agreement from CDFW have been obtained or have been determined by the regulatory agencies to not be required. If regulatory permits are required, Prior to the initiation of vegetation removal or tract improvements, the applicant shall retain a qualified biological monitor to ensure compliance with all Clean Water Act, , City of San Luis Obispo stormwater and water quality requirements, and CDFW permit requirements during work adjacent to the creek. The monitor shall be present during the installation of the construction fencing delineating the limits of work in relation to the edge of riparian, creek top of bank, and 20-foot creek setback buffer, as described in Mitigation Measure BIO-6. Since the Cambria morning glory compensatory mitigation site is to be located within this buffer, the monitor shall direct appropriate wildlife exclusion and erosion control BMPs to protect riparian habitat during site preparation for planting. The monitor shall be present during construction of the rip rap pad and any other work within the creek setback area on stormwater structures. The monitor shall also oversee removal of non-native tree species and site preparation for tree planting within the setback. If a Habitat Mitigation and Monitoring Plan (HMMP) is required by the regulatory agencies, the applicant shall provide a copy of the plan to the City and the biological monitor shall be responsible for successful implementation of the plan. BIO-11 Record a Biological Easement and Biological Easement Agreement protecting riparian area: A Biological Easement and Biological Easement Agreement shall be recorded in conjunction with the final map recordation. The easement agreement shall be developed by the applicant in a format provided by the City. The following activities are permitted within the biological easement, subject to the review and approval by the City Sustainability and Natural Resources Official: 22. Stormwater improvements. Page 139 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 74 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 23. Removal of non-native trees. 24. Restoration and creek bank stabilization activities. No future paving or structures shall be permitted within the biological easement. Creek setback standards shall be applied to the easement area, consistent with municipal code requirements. Monitoring Program: These conditions and measures shall be noted on Final Map and all grading and construction plans. The City Community Development Department and Natural Resources Manager shall verify compliance. Cultural Resources CR-1 Discovery of Previously Unidentified Cultural Resources. In the event that historical or archaeological remains are discovered during ground-disturbing activities associated with the project, an immediate halt work order shall be issued, and the City Community Development Director shall be notified. A qualified archaeologist shall conduct an assessment of the resources and formulate proper mitigation measures, if necessary. After the find has been appropriately mitigated, work in the area may resume. These requirements shall be noted on the project’s final map and all improvement/construction plans. CR-2 Discovery of Human Remains. In the event that human remains are exposed during ground-disturbing activities associated with the project, an immediate halt work order shall be issued, and the City Community Development Director shall be notified. California Health and Safety Code Section 7050.5 requires that no further disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains shall occur until the County Coroner has made the necessary findings as to origin and disposition pursuant to PRC Section 5097.98. If the remains are determined to be of Native American descent, the coroner shall notify the Native American Heritage Commission (NAHC) within 24 hours. These requirements shall be noted on the project’s final map and all improvement/construction plans. Monitoring Program: These conditions shall be noted on Final Map and all grading and construction plans. The City Community Development Department shall verify compliance, including preparation and implementation of the Monitoring Plan, and review and approval of cultural resources monitoring reports documenting compliance with required Mitigation Measures. Noise N-1 For the entire duration of the construction phase of the project, the following BMPs shall be adhered to: 1. Stationary construction equipment that generates noise that exceeds 60 dBA at the project boundaries shall be shielded with the most modern noise control devises (i.e., mufflers, lagging, and/or motor enclosures). 2. Impact tools (e.g., jack hammers, pavement breakers, rock drills, etc.) used for project construction shall be hydraulically or electrically powered wherever possible to avoid noise associated with compressed- air exhaust from pneumatically powered tools. 3. Where use of pneumatic tools is unavoidable, an exhaust muffler on the compressed air exhaust shall be used. 4. All construction equipment shall have the manufacturers’ recommended noise abatement methods installed, such as mufflers, engine enclosures, and engine vibration insulators, intact and operational. 5. All construction equipment shall undergo inspection at periodic intervals to ensure proper maintenance and presence of noise control devices (e.g., mufflers, shrouding, etc.). N-2 Construction plans shall note construction hours, truck routes, and all construction noise BMP, and shall be reviewed and approved by the City Community Development Department prior to issuance of grading/building permits. The City shall provide and post signs stating these restrictions at construction entry sites prior to commencement of construction and maintained throughout the construction phase of the project. All construction Page 140 of 1225 ER # EID-0170-2020 CITY OF SAN LUIS OBISPO 75 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 workers shall be briefed at a preconstruction meeting on construction hour limitations and how, why, and where BMP measures are to be implemented. Monitoring Program: These measures shall be incorporated into Final Map and project grading and building plans for review and approval by the City Community Development Department. Compliance shall be verified by the City during regular inspections. Tribal Cultural Resources TC-1 Culturally Affiliated Native American Monitor. A representative from the Salinan Tribe shall be notified prior to any ground disturbing activities to provide for on-site monitoring. If cultural resources are encountered during subsurface earthwork activities, all ground disturbing activities within a 25-foot radius of the find shall cease and the City shall be notified immediately consistent with the requirements of Mitigation Measures CR-1 and CR-2. Monitoring Program: These measures shall be incorporated into Final Map and project grading and building plans for review and approval by the City Community Development Department. Compliance shall be verified by the City during regular inspections. Wildfire WF-1 Vegetation/Fuel Management Plan. Prior to issuance of any construction permit, the applicant shall provide a vegetation/fuel management plan prepared by a registered professional forester or certified arborist for each lot. The plan shall identify fuel load reduction techniques, including vegetation removal and trimming, to increase defensible space around residential structures and driveways/access roads. The plan shall also identify appropriate standards for installation of new landscaping, such as requirements for drought-tolerant and fire-resistant species. WF-2 Additional Fire Hazard Reductions. Future development would incorporate the following fire reduction methods identified by the 2020 Wildland Fire Protection Report (Neumann)to reduce wildland fire risk: 1. Rain gutters, when not adequately maintained, will collect leaf material which becomes a receptive fuel bed for embers and sparks and can then transmit fire underneath the non-combustible roof materials. Rain gutters should be protected by noncombustible leaf shields or not allowed. 2. Record on all lots a deed restriction that allows for only non-combustible fences and decks in the subdivision. 3. Record on all lots a deed restriction that allows for fire resistant landscaping in the back yards of the subdivision. 4. Require enclosed eves on all structures within the subdivision. 5. Install fireproof vents on all structures (fire-rated, flame and ember resistant). 6. Working with the biologist, remove the non-native vegetation in the creek, riparian area, 7. reduce the fuel load. 8. Install a non-combustible wall (block or steel stud /stucco) wall 36 inches in height all around the northern perimeter of the subdivision. The wall shall begin at the westernmost property line and continue to the 20-foot setback at the west side of the creek, and shall continue beginning at the 20-foot setback at the east side of the creek, terminating at the property line of CAL FIRE Station #12. The purpose of this wall is to interrupt fire progression from the north onto the proposed lots without obstructing the very desirable view of the open space. Monitoring Program: This measure shall be incorporated into Final Map and noted on all grading and construction plans. The City Community Development Department shall verify compliance through initial and regular inspections.

BOX 318 SAN LUIS OBISPO, CA 93406 805-748-5837 Environmental Consulting Services MEMORANDUM Date: July 1, 2021 To: Mr. Jim Flagg Organization: Alice Jo Meinhold Survivors Trust From: Kevin Merk Email: kmerk@kevinmerkassociates.com cc: Katie Rollins, Cannon Re: Westmont Avenue TTM 3157 – Response to Comments Regarding Biological Resources During and following the Planning Commission hearing for the subject project, several comments related to biological resources were received from the public, and this memorandum addresses three topics of concern. Specifically, public comments raised concerns with the proposed project resulting in potential impacts to the California red-legged frog (Rana draytonii), the burrowing owl (Athene cunicularia), and the riparian and wildlife corridor along the existing creek. We provide the following information to direct you to the analysis provided in our Biological Resources Assessment (BRA) prepared for the project in August 2020 along with additional information as warranted. California Red-legged Frog The Biological Resources Assessment provided a characterization of the unnamed drainage feature that traverses the site, which is locally known as Twin Ridges Creek (refer to Section 3.2). This intermittent to ephemeral stream had a narrow channel with shallow, continuously flowing water at the time of the March 28, 2020 site visit and one small pool less than six (6) inches deep (KMA 2020). The channel morphology indicated that during years with higher rainfall, water would flow through the drainage without forming pools deep enough to support California red-legged frogs. No emergent vegetation was present, and wetland vegetation along the channel consisted of vernal marsh species, which indicated a lack of permanent inundation (refer to Section 3.4.3). The background review coupled with the field work conducted for the BRA (as well as our many years of experience working with this species) determined that the California red-legged frog was "unlikely" to occur on the property based on the lack of suitable habitat and separation from known breeding sites to the north (Appendix E, page E-10). It is important to note that breeding habitat is associated with still or slow moving water that is greater than two (2) feet deep surrounded by dense, shrubby riparian or emergent vegetation (USFWS, 2002; Hayes and Jennings, 1989). Typical breeding sites maintain deep pools at least into July (USFWS, 2002). Individuals may move through upland grasslands, coastal scrub and riparian areas during wet weather while foraging or moving between breeding ponds (USFWS, 2002). During dry periods, the frog is rarely encountered far from water. Page 157 of 1225 Westmont Avenue TTM 3157 Project Response to Comments Regarding Biological Resources 2 The onsite drainage was considered to be unsuitable for California red-legged frogs, and the grassland and riparian habitats would be marginally suitable as upland and/or dispersal habitat, but only if there were aquatic sites with breeding populations within 1.0 mile that are not separated from the site by barriers to dispersal (BRA pages 25 and 29). The only recorded populations within the dispersal capabilities of the frog are on the north side of Highway 1, which is a barrier to movement. Additionally, the site is surrounded on three sides by dense urban development, and thus does not provide significant linkage to extensive open space to the south, east or west (BRA page 27). A comment letter received by the City suggests that a "permanently wetted" branch of Twin Ridge Creek downstream from the project site may provide suitable habitat for the California red-legged frog. This branch is not mapped in the National Wetlands Inventory (BRA Figure 2), but it is identified as an intermittent stream on the 1965 San Luis Obispo U.S. Geological Survey topographic quadrangle. It originates on the east side of Bishop Peak and has a larger drainage area than the onsite creek segment. It appears that the reach of the drainage indicated as "Perennial Portion of Twin Ridges Creek" in the letter may be a remnant channel from the drainage's natural location. The City's (2014) General Plan Conservation and Open Space Element, Figure 9 Creeks and Wetlands, indicates that this branch was diverted from its former location to a culverted section along Westmont Avenue just upstream from the project site, which then empties into the onsite drainage along its northern boundary. Therefore, it appears that the flows from the drainage’s headwaters were diverted away from the segment indicated on map provided. Aerial photography from Google Earth shows no channel or riparian habitat upstream from the indicated location because the area along and west of Jeffrey Avenue has been entirely developed. In addition, the hydrology of the drainage has been altered from its historic regime and now includes urban runoff and nuisance flows from residential irrigation and other uses. The areas identified as “Perennial Portion of Twin Ridges Creek” were visited by KMA's principal biologist, Kevin Merk, on June 10, 2021. The drainage originated from a storm drain pipe below residential development, and had a small pool at the outfall (6 feet wide by 14 feet long and 4 inches deep). Based on evidence of past flow and channel morphology, the pool could reach a maximum depth of approximately 18 inches. Please refer to the Photo Plate provided below. Downstream from this area were two small pools formed by anthropogenic materials stacked in the channel, with water two (2) to three (3) inches deep (maximum size estimated at 3 feet by 5 feet and 6 inches deep; 2 feet by 3 feet and 4 inches deep). There was no flow between the pools. Residential structures were along the top of bank and the streambank below the homes was armored with stacked concrete sacks. Extensive cover of non- native English ivy occurred throughout the area. Sparse wetland plants were observed in the channel, and consisted of a small patch of sedges with taller riparian canopy cover comprised mostly of willows. This area would not be suitable for California red-legged frog breeding due to the small size of pools, insufficient water depth and lack of vegetation cover for protection. This native amphibian needs deep enough water to dive into to escape predators such as raccoons and wading birds (USFWS, 2002; Jennings and Hayes, 1994). The non-native bullfrog is also a known predator of this species. When red-legged frog tadpoles are found in streams they are in large pools with emergent wetland plants, overhanging riparian vegetation in contact with the water or undercut banks that provide the necessary hiding places to avoid predation so they can develop into young adults (USFWS, 2002; KMA personal observation). Although water persisted in this small culvert outfall pool until June in a drought year, it is too shallow and limited in extent even at the estimated bank full stage to support California red-legged frog breeding requirements. The segment of the drainage on the project site and extending further upstream to another culverted section that daylights from under urban development along Skyline Drive naturally dries in the summer and does not have any in-channel pools with suitable depth to support red-legged frogs. Please note that the commenter identified this as the “spring origin”, and it appears to be another outfall of the culverted creek that has become overgrown with weedy vegetation including several Canary Island palm trees. Additionally, there is no downstream Page 158 of 1225 Westmont Avenue TTM 3157 Project Response to Comments Regarding Biological Resources 3 habitat for this species as Twin Ridges Creek goes into an open concrete channel downstream from Highland Drive (City 2014). Moreover, no records of California red-legged frogs are present from Stenner Creek or San Luis Obispo Creek within the downtown area where individuals could breed and disperse through the creek corridor onto the site (CDFW, 2021). The entire project site falls within Unit SLO-3 of designated critical habitat for the California red-legged frog, which encompasses 116,517 acres. The BRA provides further detail in Section 3.6.4. However, the statement by a commenter that this stream in particular has been identified as red-legged frog habitat is incorrect. Based on our analysis, we concluded that the stream is too ephemeral and lacks any significant pools of sufficient depth to support adult frogs. If a known breeding site occurred nearby that was not separated from the property by a major barrier such as Highway 1, then it is possible that the drainage corridor could potentially be used by juvenile frogs during dispersal periods. However, no potential breeding sites were identified on or in close proximity to the property, and given the lack of suitable aquatic habitat in the drainage corridor, we concluded there was very low potential for a red-legged frog to disperse through the creek corridor. Please also refer to Appendix E in the BRA for additional information. Burrowing Owl The burrowing owl (Athene cunicularia), a California Department of Fish and Wildlife Species of Special Concern, was determined to have potential to occur onsite as an uncommon transient that could move through the area during the winter months due to the proximity of large grassland habitats to the north where this species has been observed. A species account and details on the evaluation of occurrence is provided on page 20 of the BRA. Burrowing owls are rare in the coastal San Luis Obispo area, and are believed to no longer nest in this region (CDFW, 2003). As detailed in the BRA, the site is highly manipulated from years of human occupation, and the onsite grassland areas are used regularly for horses and are mowed and managed. These activities and proximity to existing development reduces the potential for a burrowing owl to fly through the area and stop over at the site. This species is very sensitive to human activity and the proximity of the site to dense urban development in the city further reduces the habitat value for this species, especially considering the extensive grasslands to the north along Highway 1. While some ground squirrel activity was noted onsite and in the immediate area, no extensive burrow complexes were observed that would potentially draw a burrowing owl to the site to forage considering the expansive grassland habitat available to the north outside the city limits. Potential project impacts on burrowing owl were identified in Impact Bio-2 of the BRA, and mitigation provided to make sure the project avoids impacts to this species just in case one occurred onsite prior to project activities (refer to Mitigation Measures BIO-2a and -2b). The mitigation measures require pre- construction surveys to ensure no burrowing owls are in close proximity to any construction activity. If an owl or an occupied burrow(s) is located, the area will be left alone until the bird leaves the area. Because the site is small, surrounded by trees and has regular human presence, the loss of the disturbed grassland habitat as a result of the project would not have an effect on the regional population of burrowing owls. Riparian and Wildlife Corridor Comments were received concerned that the removal of large eucalyptus, redwood and other trees along the riparian zone would decrease roosting habitat for raptors. The project proposes only to remove non- native species from the riparian corridor and this activity is recommended by the project's Fire Protection Plan to reduce fuel loads. Please note that the redwood trees in the riparian corridor would not be removed, and only the eucalyptus and acacia trees would be removed as part of the habitat enhancement effort. The effects of these actions are described in Section 4.1.2 of the BRA. Areas where non-native trees are to be removed and other locations within the creek setback area would be designated as open Page 159 of 1225 Westmont Avenue TTM 3157 Project Response to Comments Regarding Biological Resources 4 space and would receive native tree, shrub and grass plantings and protected through a deed restriction or other mechanism (Mitigation Measure BIO-4b). Therefore, the loss of roosting habitat if the one eucalyptus (#114) is removed would be temporary and the habitat condition of the riparian corridor will overtime be better by planting native species and increasing the overall area that is occupied by native riparian habitat. The onsite grassland area is disturbed and does not represent high quality foraging habitat given its limited area and proximity to existing urban development. Birds of prey such as hawks and great horned owls would still be able to utilize trees along the riparian corridor and in the surrounding area for perches even with the development of the proposed project. The project proponent understands the importance of maintaining open space adjacent to the riparian area and creek. This has been addressed by incorporating a voluntary 20-foot setback from the riparian area that will be enhanced through non-native species removal and replanting with native trees, shrubs and grasses. The creek corridor will be protected from human disturbance, as described in the Project Description, Section 1.1 and Mitigation Measure BIO-4b #7. As described in Section 4.1.4, the property away from the creek corridor does not provide linkage to other suitable habitat areas because it is surrounded on three sides by urban development, but it can be used as a stopover point by wildlife species that are somewhat adapted to human development. Biological monitoring to ensure protection of the setback area during the construction phases has been provided in Mitigation Measure BIO-4b #4, and any proposed habitat enhancement or mitigations associated with future drainage improvements would also be managed and monitored for a period after development to ensure the replaced vegetation is established and self-sustaining. It is envisioned that the wildlife (i.e., deer, opossum, raccoon) that currently use the creek corridor will continue to use it post-development, as it connects with undeveloped lands to the north. As proposed, the habitat enhancement methods within the riparian corridor (i.e., removal of non-native species and replanting with natives) will increase the value of this portion of the site, and maintain it as a wildlife corridor connecting areas to the north with habitat features to the south of the property.

Page 162 of 1225 MEMO 1 of 4 DATE: July 1, 2021 TO: Mr. James Flagg CC: Andy & Tim Meinhold, Alice Jo Meinhold Survivors Trust FROM: Katie Rollins, P.E. (Cannon) SUBJECT: Tract 3157 Review for preservation of trees PROJECT NO.: 190306.02B 1. Background This memo has been prepared under the direction of the Meinhold Family and the City of San Luis Obispo Community Development Department in response to the request from the Planning Commission at the Wednesday May 26, 2021 public hearing regardin g item 2 on the agenda (The Project). The Project is located at 500 Westmont Ave. It proposes Tentative Tract Map (Tract 3157) to create 23 residential lots on an existing 4.98ac site with the Low -Density Residential (R-1) zone. The project includes the extension of Stanford Drive, which will connect to an extension of Cuesta Drive. On May 26th, the Planning Commission approved a motion on The Project to continue the matter to a future date certain for completion of environmental review, incorporating all comments received at the meeting, and giving the opportunity for additional public comment, and to direct staff to work with the applicant to look at alternative grading concepts to preserve as many trees as possible. Additionally, on May 17, 2021 the Tree Committee approved a motion on the project to make an effort to preserve trees #91, #33, #34, and #114. This memo explores the feasibility of preserving as many trees as possible onsite, as well preserving trees #91, #33, #34, and #114 as it relates to civil engineering scope of work (grading, drainage, site layout and utilities) for the 23-lot project. 2. City Ordinances and Standards Guiding Design Below is a list of City standards & ordinances that have been incorporated into the design: • Retaining walls greater than three feet in height, 2:1 slopes or other significant landform alterations are strongly discouraged (Municipal Code 16.18.020) • Combined fence and retaining wall height shall not exceed nine feet from the lower side (Municipal codes 17.70.070.F.3) • Natural contours shall be preserved in new subdivisions to the greatest extent possible. (Municipal Code 16.18.020) • Driveway slopes shall not exceed 20% and shall include vertical curves (City Engineering Standard 2130) • Longitudinal grade of streets must comply with the current edition of AASHTO manual “A Policy of Geometric Design of Highways and Streets” (Uniform Design Criteria 3.1.4) Page 163 of 1225 MEMO 2 of 4 • Runoff shall be managed to prevent any significant increase in downstream peak flows, including 2-year, 10-year, 50-year, and 100-year events. Significant generally means an increase of over 5 percent at and immediately downstream of the project site. (Waterways Management Plan, Drainage Design Manual 3.3) • Retain 95% percentile storm event via infiltration in WMZ 1 (Post Construction Stormwater Management Requirements) • Treat or retain 85% percentile storm event in WMZ 3 (Post Construction Stormwater Management Requirements) 3. Feasibility for Preservation of Trees along Perimeter and Side yards The standards mentioned above limit the ability to save additional trees for the proposed development. Typically, to preserve trees no grading is allowed within the limits of the dripline unless specifically reviewed and approved by an arborist and special measures are implemented. Preservation of additional trees along the south perimeter of the site were considered. This would be accomplished by matching existing grade at the limits of the existing driplines. Matching grades at the limits of the existing driplines would require walls greater than 3’, and in some cases greater than 6’ to meet pad elevations that meet maximum driveway slope standards. Walls greater than 6’ in height, or walls greater than 3’ in height with a 6’ fence on it would require an exception to City standards. This grading concept is not feasible because it does not meet all City standards without variances. Additionally, the area along the south property line is being proposed for stormwater treatment and retention to meet the requirements of post-construction stormwater management. Preservation of trees within proposed sideyard setbacks (#2, #8, #3, #6) and within proposed road parkway strip (#45, #35) were considered. All these trees either extend into the building footprint area, or grading is required at their location to accommodate the adjacent pad elevations and road grading. The road is graded to match existing contours as best as possible while maintaining appropriate longitudinal grades. Efforts to preserve the trees discussed above cannot be met with alternative grading concepts due to the restrictions of the City codes and ordinances for max wall heights, maximum driveway slopes, post construction stormwater requirements, and road slopes and grading. 4. Feasibility for Preservations of trees #148 to #162 Trees #148 to #162 (3”-10” Acacias) are considered for preservation due to their proximity to the creek. Trees #148 to #162 lie adjacent to the creek bank on lot 3 and were recommended for removal per the “Westmont Subdivision Wildland Fire Protect Report” (Nuemann 2020) and the “Biological Resources Assessment” (Merk 2020). From a civil engineering perspective, protecting these trees would reduce the buildable area of Lot 3 to an 87’x38’ pad (assuming no setback to the trees). Because of other constraints and recommendations – such as native plant mitigation and fuel load reduction, these trees may be removed and replaced with natives. The buildable area for the lot may be maximized by relocating the stormwater treatment area to the sideyards of Lots 1 and 2 as shown in Attachment 1. 5. Feasibility for Preservation of tree #91 The tree committee specifically requested tree #91 (16”, 8” coast live oak) be reviewed for feasibility of preservation. Tree #91 lies within the proposed underground detention basin system (Stanford Basin). Page 164 of 1225 MEMO 3 of 4 The Stanford Basin is designed to the minimum volume necessary to mitigate the 100-year flow to match pre-developed conditions to Twin Ridge Creek as required by the Drainage Design Manual. The basin was thoughtfully located near the low point of the site so that it could capture as much runoff as possible from the site but still be high enough to allow the outlet to drain to the existing creek. Alternative grading concepts for the drainage basin include an above ground basin, which would require a larger footprint, likely not fitting on the site, and provide less future usable space as it would need to be fenced off. An above ground basin would not provide preservation of Tree #91. Any relocation of the current Stanford Basin storage volume is not feasible without negatively impacting the building areas of adjacent lots. 6. Feasibility for Preservation of tree #33, #34 The tree committee specifically requested trees #33 (33” eucalyptus), and #34 ( 54”, 41” eucalyptus) be reviewed for feasibility of preservation. Trees #33 and #34 have trunks in the pad area for lot 23, and their dripline extends over the detention basin. Preserving trees #33 & #34 would render Lot 23 unbuildable because their driplines extend into the building area such that only a 10’x30’ buildable pad (not including required fire setbacks from fuel loads) would remain. Additionally, the driplines for trees #33 & #34 extend over the proposed underground detention system. Retaining trees #33 and #34 on Lot 23 is therefore infeasible because of required storage volume of the detention basin. 7. Feasibility for Preservation of tree #114 The tree committee specifically requested tree #114 (42” eucalyptus) be reviewed for feasibility of preservation. Tree #114 is adjacent to the creek and is located on Lot 2. Preserving tree #114 would require an arborist’s approval of an approximately 12 LF encroachment into the dripline of the tree and an adjustment to the buildable area of Lot 2 as shown on Attachment 1. The grading concept shown in Attachment 1 provides space for the LID stormwater basin and reduces the buildable area of Lot 2 to reduce ground disturbance under the tree. We recommend a condition be added to obtain the arborist’s evaluation of the feasibility of protecting tree #114 at the time of subdivision improvements (pad grading) and/or at building permit submittal. Alternatively, tree #114 could be removed and replaced with a native oak tree as deemed appropriate by biologist and staff. 8. Recommendations The plan as proposed meets the requirements set forth by the City of San Luis Obispo. As described above, it is infeasible to maintain reasonable buildable areas for all the project’s lots and retain trees #91, #33 and #34. We recommend that the following condition be added to the project in order to maximize the preservation of trees onsite: Page 165 of 1225 MEMO 4 of 4 • Obtain the arborist’s evaluation of the feasibility of protecting tree #114 at the time of subdivision improvements and/or at building permit submittal. Alternatively, tree #114 could be replaced with a native oak tree as deemed appropriate by the biologist and staff. The decisions of the Planning Commission regarding the removal, preservation or replacement of the trees mentioned above adjacent to the creek could ultimately affect the final limits of the riparian area, and the 20’ building setbacks. At the time of building permit submittal builders may consider a setback modification request.

The proposed project involves the creation of 23 single-family residential lots on an approximately 5-acre parcel with an existing single-family residence and auxiliary structures that would be removed. The property is situated within the northwestern edge of urban development, with dense residential development surrounding the site on three sides and the CalFire facility and California Polytechnic State University grazing lands present to the north. The purpose of this assessment was to assist the property owner with technical biological resources information to support the application for approval of the Vesting Tentative Tract Map 3157 from the City of San Luis Obispo (City). This report evaluates the potential for the subject property to support special-status biological resources, and whether these resources could be adversely affected by the proposed project. A desktop review of available background information on special-status biological resources in the project vicinity was used for this analysis. A tree survey and seasonally timed rare plant surveys were also conducted. Five plant communities or land use types were identified within the study area, and include: 1) Ornamental; 2) Developed/Ruderal; 3) Riparian; 4) Annual Grassland; and, 5) Rock Outcrop. A prominent feature of the property is landscaped areas and Ornamental plantings, which represent a diversity of horticultural specimens. In the western portion of the property, an unnamed, intermittent drainage that is locally known as Twin Ridge Creek runs from north to south, and is surrounded by Riparian forest. The stream originates on the northeast slope of Bishop Peak a short distance from the property, and is a tributary to San Luis Obispo Creek. The Riparian habitat had a mixture of native coast live oak and willows along with a variety of non-native ornamental species that had become established or were intentionally planted. The Riparian habitat is considered to be a sensitive natural community by the California Department of Fish and Wildlife (CDFW) and a sensitive resource by the City. Annual Grassland on the property was subdivided into paddocks that are periodically used for horse grazing, and due to a history of disturbance was dominated by non-native species. There was one small rock outcrop in the western portion of the property, which was not serpentine and did not represent a significant feature due to its small size. Soils were of dark, loamy clays. Elevations on the property range from 287 to 333 feet (87 to 101 meters) above mean sea level. A total of 177 trees were identified during the tree surveys, consisting of ornamental species, species native to the region that were planted, and naturally occurring native species within the Riparian habitat. The background review determined that four special-status plant species recorded from the vicinity of the site had potential to occur within the property, and seasonally timed rare plant surveys were conducted to determine their presence or absence. One of these species were found onsite, which was the Cambria morning-glory (Calystegia subacaulis ssp. episcopalis; California Rare Plant Rank [CRPR] 4.2). It was found in four occurrences totaling 1,076 square feet and comprised of approximately 300 plants. The focused rare plant surveys conducted for this investigation were floristic in nature and covered all parts of the property to ensure thorough coverage during the blooming period of the species with potential to occur; therefore, no further surveys are recommended. The project will impact the Cambria morning-glory occurrences , and compensatory mitigation involving seed, whole plant collection and planting, and/or salvaged topsoil to be spread in a designated open space location. Five years of monitoring and adaptive management measures to ensure no net loss of the species onsite is recommended. Page 171 of 1225 KMA 468 Westmont Avenue, San Luis Obispo, CA Biological Resources Assessment Alice Jo Meinhold Survivors Trust iii Three invertebrate, one reptile, nineteen bird, and four mammal species were considered to have potential to occur on the property. No fish species could occur because the onsite drainage is too ephemeral to support fish. The property occurs in designated critical habitat for the California red- legged frog (Rana draytonii), but the drainage is too ephemeral to support aquatic habitat of this species. The Riparian habitat along the drainage could be suitable dispersal habitat for the frog, and Annual Grassland could be suitable upland habitat, but there were no documented occurrences of the species within 1 mile of the site that were not separated by barriers to movement. The project was determined to have potential to affect burrowing owl (Athene cunicularia), northern California legless lizard (Anniella pulchra), San Diego desert woodrat (Neotoma lepida intermedia), protected nesting birds and roosting bats. Mitigation prescribed for these species involves seasonal restriction of initial construction phases (to avoid burrowing owl and water quality effects), if possible; preconstruction surveys and avoidance/relocation; Worker Environmental Awareness Program; wildlife exclusion/silt fence to delineate allowable work area from protected creek setback area; and, biological monitoring during initial construction phases. The impact area for the proposed subdivision would occur in the Developed/Ruderal and Ornamental land uses associated with an existing residence, and grazed Annual Grassland, which do not represent significant value to wildlife. A 20-foot setback along the drainage has been designated from the top of bank or edge of riparian, whichever is farther. However, in several areas grading is proposed within the creek setback to create side slopes needed for the level building pads. A rip rap pad at the outfall of a stormwater retention area is planned very close to or within the creek channel, and underground stormwater treatment/retention areas are planned for within the creek setback area. A wetland delineation will be needed to determine the extent of areas under the jurisdiction of U.S. Army Corps of Engineers under Section 404 of the Clean Water Act; Regional Water Quality Control Board under Section 401 of the Clean Water Act and Porter-Cologne Water Quality Control Act; and, CDFW pursuant to California Fish and Game Code Sections 1600 et seq. Any work conducted in jurisdictional areas would require permitting from these agencies and the preparation and implementation of a Habitat Mitigation and Monitoring Plan (HMMP). The project's Fire Protection Plan calls for the removal of non-native trees in the Riparian habitat. Well over 100 trees planted in landscaped and ornamental areas would be removed, and in compliance with the City Municipal Code for Tree Removal 12.24.090 these trees would need to be replaced at a 1:1 ratio. The HMMP would cover the techniques and monitoring methods for compensatory mitigation that may be needed in compliance with agency permits for jurisdictional area impacts, as well as some of the City-required tree planting within the creek setback zone. It is expected that additional tree planting for City requirements will be incorporated into the residential lots. To prevent indirect effects of stormwater runoff from construction areas on the Riparian habitat onsite and in downstream areas, Best Management Practices (BMPs) and biological monitoring of site disturbance activities and implementation of the BMPs are also required. Temporarily disturbed areas shall be planted with a native seed mix to stabilize these areas. The proposed project did not trigger any of the criteria that would meet a mandatory finding of significance under the California Environmental Quality Act (CEQA). Mitigation measures for the six additional impacts evaluated under CEQA described herein would reduce project effects below a level of significance. Page 172 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 1 1.0 INTRODUCTION Kevin Merk Associates, LLC (KMA) conducted this biological resources assessment (BRA) for a proposed subdivision of an approximately 5-acre parcel at 468 Westmont Avenue, San Luis Obispo, San Luis Obispo County, California. The property is identified as Assessor's Parcel Number (APN) 052-496-001, and zoned Low Density Residential (R-1). The project is located 0.3 mile to the northwest of the intersection of Highland Drive with Highway 1, within the Urban Reserve Limits of the City of San Luis Obispo (Figure 1). It is on the U. S. Geological Survey (USGS) San Luis Obispo 7.5-minute topographic quadrangle (T 30 S, R 12 E, northeast corner of the southwest corner of Section 22; 35.301156° N, -120.678971° W). The property is situated within a residential area within the northwestern edge of urban development in the City of San Luis Obispo (Figure 2). Dense residential development surrounds the property on its western, southern, and eastern boundaries. A CalFire station is along the northern boundary, and an expanse of grazed grassland beyond. The grassland is California Polytechnic State University (CalPoly) lands and is contiguous with the northern border of the property in the western portion. Farther to the west and south are open space areas for Bishop Peak and Cerro San Luis. On the east side of Highway 1 is CalPoly's agricultural fields and livestock grazing areas. The purpose of this assessment is to assist the property owner with technical biological resources information to support the application for a proposed lot subdivision with the City of San Luis Obispo (City). This report evaluates the potential for the project site to support special-status biological resources (plants, animals, sensitive natural communities, and designated critical habitat) for the California Environmental Quality Act (CEQA) review to be conducted by the City for the project. This BRA evaluated the site’s existing natural conditions to determine whether special- status biological resources may be present onsite and could be adversely affected by the proposed project. Also included in this investigation is a tree survey, as well as seasonally timed rare plant surveys. 1.1 Project Description As shown on the vesting tentative tract map prepared for the project by Cannon (August 17, 2020; included as Appendix A), the project involves the creation of 23 single-family residential lots. The existing residence, accessory buildings, and driveway would be removed, as well as most of the ornamental trees scattered throughout the property. The lots would range in size from 6,000 to 24,451 square feet, with building envelopes permitted for two-story residences ranging from 1,934 to 3,766 square feet. The northern end of Stanford Drive that is used to access the current residence would be expanded and the alignment would bend to the east to connect with Cuesta Drive. A majority of the lots would have access from this new extension, and the remainder of the lots would access Westmont Avenue on its eastern or western dead ends. The building envelopes have been designed to avoid the riparian habitat surrounding a drainage that runs north to south through the western portion of the property (known locally as "Twin Ridge Creek"). The edge of riparian habitat and limits of the top of bank, whichever is farther from the creek centerline, were delineated in the field and a 20-foot creek setback was developed to separate site development from the creek corridor. Some grading of the development pads would occur in the setback. The project's stormwater plan has a combination of harvesting, infiltration, evapotranspiration and biofiltration treatment, along with the underground stormwater retention devices. The project would include several retaining walls, and along the northern border of lots 7-9, a 3-foot tall non- combustible wall would be constructed, as detailed in the project's wildland fire protection report.

FESA provisions protect federally listed species and their habitats from unlawful take, which is defined as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any of the specifically enumerated conduct.” Under these regulations, "harm" may include significant habitat modification or degradation that kills or injures wildlife. Candidate species are not afforded legal protection under FESA; however, Candidate species typically receive special attention during the CEQA environmental review process. CESA provides for the protection and preservation of native species of plants and animals that are experiencing a significant decline which if not halted would lead to a threatened or endangered designation. Habitat degradation or modification is not expressly included in the definition of take under CESA. CDFW maintains a list of Species of Special Concern for those species in which declining population levels, limited ranges, and/or continuing threats have made them vulnerable to extinction. The goal of designating species as special concern is to halt or reverse their decline early enough to secure their long-term viability. Species of Special Concern may receive special attention during environmental review, but do not have statutory protection. FESA and CESA emphasize early consultation to avoid impacts on Threatened and Endangered species. As part of the consultation process, project proponents are directed to develop appropriate mitigation plans to offset project effects on listed species and their habitats. Sensitive natural communities are those native plant communities listed in the CNDDB (CDFW 2020a) as rare or of limited distribution. They are evaluated using NatureServe's Heritage Methodology to assign global and state ranks based on rarity and threat, and these ranks are reviewed and adopted by CDFW's (2020b) Vegetation Classification and Mapping Program (VegCAMP). Evaluation with the state (S) level results in ranks ranging from 1 (very rare or threatened) to 5 (demonstrably secure). Those with ranks of S1 to S3 are to be addressed in the environmental review process under CEQA (CDFW 2020b). Critical habitat is designated for species listed under FESA, and are areas that contain the physical or biological features which are essential to the conservation of those species and may need special management or protection. Critical habitat designations affect only federal agency actions or federally funded or permitted activities. Activities by private landowners are not affected if there is no federal nexus. Rare plants are those defined as occurring on California Rare Plant Rank (CRPR) 1A, 1B, 2A, 2B, 3 and 4 developed by the CDFW working in concert with the California Native Plant Society (CNPS; CDFW 2020c). Rank 4 species are a watch list, and typically do not meet CEQA's rarity definition (Section 15380), but are included here because they may be of local concern. The CRPR definitions are as follows: Page 176 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 5 • Rank 1A: Presumed extirpated in California and either rare or extinct elsewhere. These species are presumed extirpated because they have not been recorded in the wild in California for many years. • Rank 1B: Rare, threatened or endangered in California and elsewhere. Plants that are rare throughout their range and the majority in this rank are endemic to California. • Rank 2A: Presumed extirpated in California, but more common elsewhere. These species are presumed extirpated because they have not been recorded in the wild in California for many years, but they are common outside of the state. • Rank 2B: Rare, threatened or endangered in California, but more common elsewhere. Plants that have ranges that extend into California, where they are rare, but are common in areas outside of the state. • Rank 3: Plants needing more information - A review list. Information necessary to assign the species to one of the lists or reject them is lacking. Most species in this rank are taxonomically unresolved. • Rank 4: Plants of limited distribution - A watch list. Species of limited distribution or infrequent occurrence throughout their range in California but which their vulnerability to extirpation appears low at this time and should be monitored. Additionally, the CRPR system further assigns threat codes as a decimal extension to the rank, ranging from 1 to 3. CRPR 3 species do not have a threat code due to insufficiency of information needed to assign it, and CRPR 1A and 2A also do not have threat codes because they not know to currently occur in California. The threat code extensions are as follows: • .1: Seriously threatened in California. More than 80% of occurrences are threatened and there is high degree and immediacy of threat. • .2: Moderately threatened in California. Approximately 20 to 80% of occurrences are threatened and there is a moderate degree of immediacy of threat. • .3: Not very threatened in California. Less than 20% of occurrences are threatened and the is a low degree and immediacy of threat, or no current threats are known. Raptors (e.g., eagles, hawks, and owls) and their nests are protected under both federal and state regulations. Birds of prey are protected in California under the California Fish and Game (2001) Code Section 3503.5. Disturbance that causes nest abandonment or loss of reproductive effort is considered take by CDFW. Eagles are protected under the Bald and Golden Eagle Protection Act. The federal Migratory Bird Treaty Act (MBTA) applies to many bird species, including common species, and prohibits killing, possessing, or trading in migratory birds, including whole birds, parts of birds, bird nests, and eggs. The act restricts construction disturbance during the nesting season that could result in the incidental loss of fertile eggs or nestlings or otherwise lead to nest abandonment. The City of San Luis Obispo Municipal Code for Tree Removal 12.24.090 discourages the removal of healthy trees that present no threat to people or property, and requires a permit for tree removal. For properties zoned R-1, as in the case of the subject property, a tree removal permit is not needed if all of the following conditions exist: Page 177 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 6 • The tree is a designated native species and the trunk is less than ten inches in diameter as measured at standard height (4' 6" from the ground), or for non-native species the trunk is less than twenty inches in diameter; and • The tree is not located in a creek setback area; and • The tree is not a designated street tree, and is not located within ten feet of the back of the sidewalk; and • Planting or retention of the tree was not a condition of development; or • The tree is a palm and the trunk is less than twelve inches in diameter. Issuance of tree removal permits from the City require a site plan showing the location, species and size of any tree proposed for removal, with the trees uniquely identified by number. Information must be provided supporting the reason for tree removal, including photographs or diagrams. A replanting plan shall also be prepared detailing compensatory tree planting with the size, location and species of trees to be planted. The application may also require an arborist report, site plan showing the drip line of each tree, and site-specific tree protection plan for trees that would remain. CEQA defines a significant effect on the environment as “a substantial, or potentially substantial, adverse change in the environment.” Projects that may have significant effects are required to be analyzed in an Environmental Impact Report (EIR). Under CEQA, a project’s effects on biotic resources are deemed significant where the project would do any of the following: • Potentially substantially degrade the quality of the environment; • Substantially reduce the habitat of a fish or wildlife species; • Cause a fish or wildlife population to drop below self-sustaining levels; • Threaten to eliminate a plant or animal community; • Substantially reduce the number or restrict the range of an endangered, threatened, or rare species; or, • Have possible environmental effects that are individually limited but cumulatively considerable. In addition to the criteria above that trigger mandatory findings of significance, Appendix G of the CEQA Guidelines includes six additional impacts to consider when analyzing the significance of project effects, which may or may not be significant, depending on the level of impact. A project’s effects on biological resources could be deemed significant if the project would do the following: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by CDFW or USFWS. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by CDFW or USFWS. c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. Page 178 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 7 f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan. If the project proponent agrees to mitigation measures or project modifications that would avoid all significant effects or would mitigate the significant effect(s) to a point below the level of significance, an EIR would not be required. The project proponent would be bound to implement the mitigation measures to reduce the project effects to below a level of significance. Mitigation is not required for effects that are less than significant. 2.0 METHODS 2.1 Biological Resources Assessment Google Earth aerial imagery was employed in coordination with field surveys to define the current extent of onsite plant communities and assist in identifying potential habitat for special-status species. KMA’s Principal Biologist Kevin B. Merk and Senior Biologist Susan V. Christopher conducted a reconnaissance survey of the entire property, which was considered to be the study area for this investigation, concurrent with the first tree and rare plant survey, on March 4, 2020. This survey was conducted between 0900 and 1600 hours, and weather conditions were mostly clear with partial high clouds, wind 0 to 3 miles per hour and air temperatures in the mid to high- 60s°F. The second survey, in which additional plant and animal species observed onsite were recorded, took place on March 28, 2020 between 0930 and 1600 hours, and the weather was high clouds, wind 5 to 10 miles per hour, and air temperature 54°F at the start. Additional surveys were conducted by Kevin Merk on April 23 and May 20, 2020. The site was accessed from Stanford Drive, and the surveys were conducted by walking and visually inspecting all portions of the study area. All plant and wildlife species observed during the surveys were recorded (Appendix B). Habitat types were mapped on aerial imagery, and dominant plant species in each habitat type were determined. Plant taxonomy followed the Jepson Flora Project (2020), and nomenclature for animals is reported as it appears in the CNDDB (CDFW 2020a) or as updates are available (California Herps 2020). Plant communities and land use types were mapped on ESRI (2020) aerial imagery. Classification of the onsite plant communities was based on Holland’s (1986) Preliminary Descriptions of the Terrestrial Natural Communities of California and the CDFW's (2020b) Vegetation Classification and Mapping Program, which generally follows Sawyer et al.'s (2009) Manual of California Vegetation. A Guide to Wildlife Habitats in California, which is updated through the California Wildlife Habitat Relationships (CWHR) System (CDFW 2020d), was also cross-referenced. Representative photographs of each of the habitat types within the study area are provided in a photo plate (Appendix C). The Web Soil Survey (Natural Resources Conservation Service [NRCS] 2020) was used to identify the soil mapping units present within the study area. The National Wetlands Inventory (NWI) was examined to evaluate the extent of any identified wetlands on the site and in the vicinity (USFWS 2020a). USGS topographic maps were also reviewed for information on hydrologic and topographic features. Designated critical habitat for species listed under FESA was identified and mapped based upon information provided in Environmental Conservation Online System (USFWS 2020b). The CNDDB (CDFW 2020a) was queried for special-status plant and animal species occurrences and sensitive natural communities within the following nine USGS 7.5-minute quadrangles: San Luis Obispo, Morro Bay North, Atascadero, Santa Margarita, Lopez Mountain, Arroyo Grande Page 179 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 8 Northeast, Pismo Beach, Port San Luis, and Morro Bay South. The records occurring within a five- mile buffer of the study area were mapped. For each of the special-status species in the nine- quadrangle CNDDB search, local distribution and ecological information was obtained from a variety of online and published sources (Hoover 1970, Jennings and Hayes 1994, Bolster 1998, Moyle et al. 2015, Thompson et al. 2016, Audubon 2020, Calflora 2020, California Native Plant Society 2020a, California Herps 2020, The Cornell Lab of Ornithology 2020a, 2020b; CDFW 2020d). Those species that occur within the San Luis Obispo and Chorro Creek watersheds, as well as each species recorded in the CNDDB within five miles, were considered to be within the project vicinity (Appendix E). Other species from the nine-quadrangle search that have limited distributions that do not include the subject area and/or are restricted to higher elevations in the Santa Lucia Range, immediate coastline and beaches, and areas north of Cuesta Grade were considered to be outside of the project vicinity. Based upon our knowledge of the local area and other sources of species occurrence records (particularly observations recorded in Calflora [2020] and The Cornell Lab of Ornithology [2020a]), we included additional special-status biological resources that have been documented in the project vicinity. For the list of all special-status species known from the project vicinity, an evaluation of those species with potential to occur onsite was performed based upon the suitability of habitat conditions on the property, and the local distribution (geographical and elevational ranges) and specific requirements (plant communities and soils) of the species considered. Definitive surveys for the presence or absence of special-status animal species were not conducted. We relied on existing information and known occurrence records in the region, coupled with our site-specific observations from other locations in the surrounding area, to make determinations for the probability of occurrence of each special-status species within the study area. Any special-status species that were observed during the site surveys are listed as "Present" in Appendix E. Those species listed as "Potential" met the following requirements: relatively recent records in the vicinity; appropriate plant community and/or soil associations onsite; and, within the elevational range and local distribution of the species. If any one of these elements was not met or considered to be marginal for the site, but the other elements were present, that species was considered "Unlikely" to occur in the study area. In situations where onsite environmental conditions were clearly inappropriate, the only records in the vicinity were very old and/or imprecise, and/or the species has a limited distribution that does not overlap the site, then those species were considered "Not Expected". For animals, if any lifestage or particular life history use (i.e., foraging) fit the requirements of the onsite conditions, even while other aspects were inappropriate for certain functions (i.e., breeding), these species were still considered to have potential to occur onsite, but the likelihood of occurring onsite along with a description of site suitability are provided in the Special-status Biological Resources Summary (Appendix E), as well as a more in-depth analysis in the text. We determined whether potentially jurisdictional wetlands or drainages, special-status plant and animal species, sensitive natural communities, and designated critical habitat could occur on or near the site. We then evaluated the potential impacts of the proposed project on each of these biological resource issues, including the six additional impacts in CEQA Appendix G. An evaluation of significance as defined under CEQA is provided for each potential impact, and mitigation is proposed to reduce impacts to a level below the significance threshold. 2.2 Tree Inventory An inventory of all trees or large shrubs onsite that were at least three (3) inches in diameter at breast height (DBH), which was approximately 4.5 feet above ground, was conducted during the Page 180 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 9 March and April surveys. Each tree within the property was identified to species (for ornamental plantings, to genus or the lowest level possible), assigned a unique number, and DBH was measured for each trunk or major (>3 inch) branch that was above approximately 4.5 feet. An aluminum tag imprinted with the identifying number was affixed to the north side of the tree at approximately 4 feet above the ground using an aluminum nail. Several trees were covered in poison oak (Toxicodendron diversilobum), and in these areas, the tree was not tagged. The location of each tree was recorded using a Trimble Geographic Positioning System (GPS) handheld unit, Trimble Ge-XH 6000, and on average the accuracy was within two to three feet due to dense canopy coverage. Tree species, DBH of each trunk, vigor (high, medium, or low), and other observations were recorded. Species that are generally considered to be shrubs and not trees (i.e., toyon), which were less than 3 inches DBH, and other species lacking a true trunk (i.e., sago palm), were not included in the tree inventory. Points representing tree centers were mapped, and the diameter of the canopy was represented on ESRI aerial photography and provided to the project engineer to be shown on site plans. 2.3 Focused Rare Plant Surveys Rare plant species were searched for during each of the four surveys. The surveys were focused on the special-status plant species identified with potential to occur onsite (see Section 3.6.1 and Appendix E), and was also floristic in nature in that all plants observed were recorded. Plant species were identified to a level necessary to determine rarity. The plant surveys were timed to coincide with the blooming periods of the special-status plant species determined to have potential to occur onsite, which is the time of year that plant species are in flower and typically the most readily identifiable. The methodology used during the surveys followed the guidance in Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Sensitive Natural Communities (CDFW 2018) and Guidelines for Conducting and Reporting Botanical Inventories for Federally Listed, Proposed, and Candidate Plants (USFWS 2000). This included walking the entire study area using evenly spaced transects to observe and document all plant species observed. The extent of rare plant occurrences found were recorded and mapped using a Trimble GPS unit. A complete list of all of the plant species observed during the survey was recorded and is included as Appendix B. 3.0 RESULTS A list of plants and animals observed during the survey is included as Appendix B. Appendix C is a plate of photographs taken during the site visit to characterize onsite conditions. Appendix D has a data table from the tree inventory. Appendix E includes a list of all special-status species, sensitive plant communities, and designated critical habitat recorded within the site vicinity, and an evaluation as to their potential presence onsite. Figure 1 is a site location map, Figure 2 shows the wetland habitats recorded in the NWI in the site vicinity, and Figure 3 is a habitat map showing the plant communities, land use types and landscape features in the study area. Figure 4 shows the locations of trees mapped during the tree inventory. Figures 5 and 6 show the locations of special- status plants and animals, respectively, within five miles of the study area. Sensitive natural communities and designated critical habitat within five miles of the study area are on Figure 7. 3.1 Existing Conditions The study area occurs at the edge of dense single-family residential development at the northern limits of the City, around CalPoly and commercial centers at the corner of Highway 1 (Santa Rosa Street) and Foothill Boulevard. The neighborhoods south of the property were developed prior to 1965, and the subject property has remained as the only larger lot in the area on the edge of town. Page 181 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 10 The neighborhoods lie between the study area and open space at Bishop’s Peak and Cerro San Luis Obispo. Highway 1 to the east has a concrete divider and is a barrier to the movement of wildlife species in a general south to north direction. The property has an existing single-family residence with a surrounding landscaped yard, sheds, outbuildings, and paved driveway to Stanford Drive. The site is encircled by vinyl split-rail fencing, which also subdivides sections of the property that are not developed for the residence into paddocks for horse grazing. Horses are rotated through the paddocks and then are off-site seasonally. In the western portion of the property, an unnamed drainage, shown as Twin Ridge Creek on project plans, runs from north to south, and is lined with riparian habitat mixed with ornamental species. Additional information about the drainage is provided in Section 3.2 below. A prominent feature of the property is landscaped areas and ornamental plantings along fence lines, which represent a diversity of horticultural specimens. Many of these areas are dominated by mature trees and shrubs that provide structure and food resources (i.e., berries and fruit) for wildlife species that inhabit suburban or edge environments, as well as vegetative screening from the surrounding urban area. Shrub species native to the region, but not occurring as native species on the site, were incorporated into ornamental plantings. Ornamental species had also escaped landscaped areas and had propagated throughout the site, particularly within the riparian habitat. Elevations on the property range from 287 to 333 feet (87 to 101 meters) above mean sea level. The highest point is in the northeast corner, and the relatively level site slopes slightly to the south toward a swale offsite along the southern boundary, and to the west to an unnamed drainage. Another gentle swale in the western portion of the site joins the unnamed drainage in the southwestern corner of the site, at the lowest site elevation. Observations of the soils in the field were of dark, loamy clays with deep soil cracks. Additional information about the soils onsite is provided in Section 3.3 below. 3.2 Hydrologic Features, Wetlands and Riparian Habitats An unnamed drainage traverses the site from the north to the south through the western portion of the study area, and is shown as an intermittent stream on the San Luis Obispo topographic quadrangle. It is known locally as Twin Ridge Creek. One branch originates 0.2 mile north of the site within the CalPoly grazing lands, and it’s headwaters reach originates in the Ferrini Ranch Open Space and passes through development along northern Patricia Drive before entering an underground culvert northwest of the property. Downstream from the property it joins other intermittent drainages on the east side of Bishop Peak and Cerro San Luis Obispo within the urban area, flowing into "Old Garden Creek" which is shown on some maps but is not named on the USGS quadrangle, then converges with Stenner Creek just upstream of Highway 101 near the Broad Street interchange. Stenner Creek joins San Luis Obispo Creek on the opposite side of Highway 101 near the Marsh Street exit. San Luis Obispo Creek flows southwest parallel to Highway 101, and bends sharply to the west at Avila Beach Drive. It becomes a tidally influenced lagoon in its lower reaches, and flows into the Pacific Ocean at San Luis Obispo Bay in Avila Beach. Within the study area, the drainage had a defined bed and bank and a small pool of water (<6- inches deep) was present during the March 4th site visit at the northern property boundary. On March 28th, there was a small amount of water flowing continuously through the property as a result of late season storm activity. Throughout most of its length onsite, the creek channel was lined by dense riparian habitat (described in Section 3.4.3 below). In openings in the tree canopy where several small farm road crossings were present, herbaceous wetland plant species were observed. A gentle swale was present in the riparian zone in the western portion of the property, Page 182 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 11 which leads into the unnamed drainage in the southwest corner. It was surrounded by riparian vegetation but no herbaceous wetland plants or flowing water were observed in this area. The creek corridor is depicted as a Freshwater Forested/Scrub Wetland in the NWI (Figure 2). No wetland or riparian plant species are present along the property's southern border, to the east of the existing driveway, where it slopes down into a construct ed channel offsite in the neighborhood area. A small, concrete-lined koi pond was present in the pool area within the developed area north of the residence. Otherwise, no ponds or areas of temporary ponded water were observed during the surveys, and none are expected to occur due to lack of topographic depressions with suitable soil conditions that could support standing water. 3.3 Soils Two soil types are present in the study area — Los Osos-Diablo complex, 9 to 15 percent slopes and Cropley Clay, 2 to 9 percent slopes, MLRA 4 (NRCS 2020). The entire eastern 75% of the property is the Los Osos-Diablo complex, which is a loamy soil that is a residuum weathered from sandstone and shale. It is a well-drained soil that does not experience flooding or ponding, and is not considered to be a hydric soil (NRCS 2020). Cropley Clay occurs in the southwestern 25% of the property, and is a clay soil that is an alluvium derived from calcareous shale. It is moderately well- drained and is not considered to be a hydric soil (NRCS 2020) 3.4 Habitat Types Five plant communities and land use types were identified within the study area, and include: 1) Ornamental; 2) Developed/Ruderal; 3) Riparian; 4) Annual Grassland; and, 5) Rock Outcrop. A description of these habitat types is given below and the areas occupied by these habitat types is shown in Figure 3. Representative photographs of these habitat types are provided in Appendix C. 3.4.1 Ornamental Various ornamental shrubs and trees have been planted along the property boundary and in areas near the residence. A large and diverse number of species are present (Appendix B), and some of the dominants include olive (Oleo europaea), Peruvian peppertree (Schinus molle), eucalyptus (Eucalyptus sp.) and various fruit trees. The non-native, ornamental species intermix with native species such as young coast live oaks (Quercus agrifolia), lemonade berry (Rhus integrifolia), blueblossum ceanothus (Ceanothus thyrsiflorus), coyote brush (Baccharis pilularis), California coffeeberry (Frangula californica) and toyon (Heteromeles arbutifolia), which most were planted to create a vegetation barrier adjacent to surrounding development. Two very large coast redwoods (Sequoia sempervirens) towered over the residence, and appear to have been planted at the time the house was constructed. The ornamental habitat type was considered to be different from landscaped areas within Developed habitat in that the planted species were large in stature and had become somewhat naturalized, and provided higher quality wildlife habitat compared to the surrounding landscaping that was included in the Developed land use category. Ornamental is not a native plant community, and is classified as an Urban habitat within the CWHR System (CDFW 2020d). 3.4.2 Developed/Ruderal Developed/Ruderal areas onsite consist of the existing residence, driveway, paving, sheds, lawn, pool, ornamental pond, parking areas, and intensively landscaped areas (Figure 3). The landscaped Page 183 of 1225 Source: E sri, DigitalGlob e, Geo Eye, E arthstar Ge ographics , CNES/Airbu s DS, USDA, USGS, AeroGRID, IGN, and the GIS User Community .

Planting beds incorporated succulents, rocks, Australian tree fern (Cyathea cooperii) and sago palm (Cycas revoluta). Various fruit trees and other edible varieties included citrus, persimmons (Diospyros sp.), apple (Malus domestica), rosemary (Rosmarinus officinalis), olive and pomegranate (Punica granatum). The driveway was lined with mature queen palms (Syagrus romanzoffiana). Shrubs included boxwood (Buxus sp.), juniper (Juniperus sp.), cheesewood and many flowering varieties. Creeping vines were represented by greater periwinkle (Vinca major), English ivy (Hedera helix), and Japanese honeysuckle (Lonicera japonica). Ruderal areas consisted of disturbed areas with mostly bare ground, such as an unpaved parking area and old horseshoe pit. Developed/Ruderal areas are an anthropogenic land use type and are not a natural community. They are classified as an Urban habitat within the CWHR System (CDFW 2020d). 3.4.3 Riparian A band of Riparian forest was present along the unnamed drainage and the lower portion of the swale in the western portion of the property. This community was dominated by coast live oak, and contained red willow (Salix laevigata) and arroyo willow (S. lasiolepis), as well as other native species that were planted or had spread naturally, such as toyon, California bay (Umbellularia californica), and what appeared to be interior live oak (Quercus wislizenii) or a potential hybrid. There were also a variety of non-native ornamental species that were intentionally planted, such as blue gum (Eucalyptus globulus), silver wattle (Acacia dealbata), firethorn (Pyracantha sp.), coast redwood, and English ivy. Native species in the understory included poison oak, coyote brush, and a young multi -stemmed southern California black walnut (Juglans californica). The understory was very dense with a high number of fallen, dead branches and woody debris. At the northern end of the riparian habitat outside of the canopy, and within an old crossing of the drainage channel in the southern part of the property, the channel had herbaceous wetland plant species. The two areas dominated by these species were small in size and thus were included in the Riparian habitat type as understory species, instead of being classified as a separate habitat type. Wetland species observed in these openings in the Riparian included common spikerush (Eleocharis macrostachya), brown-headed rush (Juncus phaeocephalus), tall flatsedge (Cyperus eragrostis) and curly dock (Rumex crispus). This habitat type corresponds to the Central Coast Live Oak Riparian Forest community described by Holland (1986) and the Quercus agrifolia/Salix lasiolepis association in VegCAMP (2020b). 3.4.4 Annual Grassland The grassland habitat onsite has been seasonally grazed by horses, and due to a history of disturbance, was dominated by non-native grassland species. Dominant species included foxtail barley (Hordeum murinum), English plantain (Plantago lanceolata), smilo grass (Stipa miliacea), Bermuda buttercup (Oxalis pes-caprae), black mustard (Brassica nigra), rattail sixweeks grass (Festuca myuros), big heron bill (Erodium botrys), and Italian wild rye (Festuca perennis). Native species were more common in the paddocks near the Riparian zone, and included California plantain (Plantago erecta), Cambria morning-glory (Calystegia subacaulis ssp. episcopalis), purple owl's clover (Castilleja exserta), and purple needlegrass (Stipa pulchra). The occurrences of purple needlegrass were scattered and were not considered to be of high enough density to warrant separation into a separate community. A large number of artichoke thistle (Cynara cardunculus) was scattered throughout the paddock farthest to the west, and surrounded by other Annual Grassland species. The Annual Grassland onsite corresponds to the Non-native Grassland community described by Holland (1986) and the Wild Oats and Annual Brome Grasslands association, which is a semi-natural alliance (CDFW 2020b). Page 185 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 14 3.4.5 Rock Outcrop There was one small rock outcrop that protruded from the Annual Grassland habitat in the western portion of the property. It had a lemonade berry (Rhus integrifolia) shrub growing over it. The rock outcrop is a landscape feature, is not a plant community, and usually would be considered to be the barren habitat type under the CWHR system (CDFW 2020b) although onsite was covered by Ornamental species. 3.5 Tree Inventory A total of 177 trees were identified during the tree surveys. A map of the locations of these trees is provided as Figure 4, and the corresponding data is included in Appendix D. A majority of the trees onsite are ornamental species that were planted as part of the landscaping. The Riparian area along the creek also had an extensive mix of non-native ornamental species. 3.6 Special-status Biological Resources The background review revealed an exceptionally large number of special-status biological resources that have been documented within the project vicinity (Appendix E). The diversity of habitats ranging from the coastline, valleys, and mountainous areas, in addition to rare habitat types such as serpentine rock outcrops, and the concentrated effort in this area to survey for and record rare species have resulted in the large number of occurrences. The study area has less than five acres of two natural, but relatively common, habitat types that were identified as having potential to support special-status species, Annual Grassland and Riparian. The Ornamental habitat type can also support many species such as birds, due to the diversity of species planted, their density, and species that provide food sources. The site is surrounded on three sides by dense urban development, but its northern border is contiguous with undeveloped habitat that is known to support rare species (CNDDB, 2020). In addition, mobile wildlife species and plant propagules could also access the site from the larger surrounding area where there is substantial open space, including reserves and recreation areas, and CalPoly and Camp San Luis Obispo lands. The special- status biological resources with potential to occur in the study area are described below. 3.6.1 Special-status Plants The background review determined that there was potential for special-status plant species to occur in the grassland and riparian/creek zone, as described in Appendix E. The following species were given high potential based on the presence of suitable soils and habitats: • California (southern) black walnut (Juglans californica) — CRPR 4.2; • Cambria morning-glory (Calystegia subacaulis ssp. episcopalis) — CRPR 4.2; • Miles' milk-vetch (Astragalus didymocarpus var. milesianus) — CRPR 1B.2; and • San Luis Obispo owl's-clover (Castilleja densiflora var. obispoensis) — CRPR 1B.2. The suite of rare serpentine endemic species were determined to not have potential to occur onsite based on the lack of suitable soils or serpentine rock outcrops. One rock outcropping observed onsite did not exhibit signs of serpentine influence. The annual species that have been recorded near the study area (Figure 5), are associated with loam or clay soils, and were identified as potentially occurring in the Annual Grassland habitats onsite are described further below and all special status plants known to occur in the region were evaluated in the table included in Appendix E.

Based on the findings of the survey effort, the special status species table provided in Appendix E identifies the majority of species as not expected to occur. The focused rare plant surveys determined that there are two special status plants present on the site, as follows. Cambria morning-glory, also called San Luis Obispo County morning-glory, is a rhizomatous perennial herb in the family Convolvulaceae. It has trailing or twining stems and a cream-colored, funnel-shaped flower. This subspecies is found in chaparral, cismontane woodland, coastal prairie, and grassland habitats, and is often associated with clay soils (Calflora 2020). This species is relatively common in the San Luis Obispo area and occurs throughout grassland habitats extending north into the San Simeon area (K. Merk personal observation). It was found in Annual Grassland habitat onsite in three occurrences to the east of the unnamed drainage and in one occurrence to the west of the drainage (Figure 3). These areas had less thatch and competition from the non- native grassland species in comparison to other areas that were composed of dense that and dominated by non-native species. The occurrences supported low densities with average areal cover estimated at three (3) plants per square meter. Given the four occurrences totaled approximately 1,076 square feet or 100 square meters, an estimate of roughly 300 plants were present onsite. Additionally, two southern California black walnut (Juglans californica) were found in the understory of the Riparian habitat onsite (trees 142 and 168) and an additional planted specimen was present along the western fenceline abutting neighboring residences (tree 177). It is considered to be a CRPR 4.2 species within its native range. It is a perennial deciduous tree in the family Juglandaceae that occurs along streams in riparian and southern oak woodland habitats. It has been planted extensively and used as root stock for the English walnut. This species was not recorded in the CNDDB in the vicinity, but there are other records in Calflora (2020) in creekside habitats near the site, especially along the lower reaches of San Luis Obispo Creek adjacent to Highway 101. Although this species is widely distributed throughout the Sacramento Valley, coastal mountains from Mendocino County to San Diego County, and various inland locations in southern California (Calflora 2020), it is native only to Santa Barbara County and areas to the south (CNPS 2020a). Hoover (1970) lists walnut species in San Luis Obispo County as having been introduced. It would not be considered to be a special-status species onsite because it is outside of its native range, and appears to have been planted and the two specimens in the creek likely have naturalized onsite from the historic plantings. Similarly, Monterey pine (Pinus radiata) is considered to be a CRPR 1B.1 species within its native range. This species is a perennial evergreen tree in the family Pinaceae. There are only three native stands in California: Año Nuevo, Cambria, and the Monterey Peninsula (CNPS 2020a). It has been planted extensively throughout the world for use as lumber, and is also a common landscape tree in the Central Coast area. This species was observed planted in Ornamental areas onsite, and was also noted as occurring in landscaped areas in the surrounding neighborhoods. The focused rare plant surveys conducted for this investigation were considered to be comprehensive, and covered all bloom periods of special-status plant species that could occur in the study area at this time. No further botanical surveys are recommended at this time. Page 189 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 18 3.6.2 Special-status Animals The CNDDB contains a moderate number of recorded occurrences of special-status wildlife species in the vicinity of the subject property. Based upon our background review of special-status species records, three invertebrate, one reptile, nineteen bird, and four mammal species were considered to have potential to occur on the property. No fish species could occur because the onsite drainage is too ephemeral to support fish, and there is insufficient aquatic habitat to support special-status amphibians that could occur in the general area. While the listing status, habitat associations and evaluation of occurrence are summarized in Appendix E, these 27 species with potential to occur are also described in further detail below. Also see Figure 6 for a map of CNDDB wildlife records within five miles of the property. The monarch butterfly (Danaus plexippus, population 1) is considered sensitive by CDFW for overwintering colonies. This species roosts colonially during the winter in wind-protected groves of eucalyptus, Monterey pine and cypress. These colonial roost sites are occupied by large numbers of butterflies throughout the winter and the individual sites are generally reused each year. "Autumnal sites" are temporary sites used for roosting that do not persist through the winter and may not be used every year. Adults nectar on a variety of blooming plants, and could potentially occur onsite periodically while foraging or migrating. Milkweed is required as a host plant for caterpillars, and was not seen in the study area. There are several records of overwintering populations and autumnal sites from relatively small stands of trees within the urban limits of San Luis Obispo (CDFW 2020a). Individual monarch butterflies were observed flying over the site during the surveys. The density of trees in the Riparian could potentially be suitable as an overwintering or autumnal site. The obscure bumble bee (Bombus caliginosus) does not have a specific listing status, but is considered sensitive in the CNDDB and could be a species of local concern. It is found along the California coast from Santa Barbara County northward. The host plants for this species occur in coastal scrub, riparian, and grassland habitats. Queens emerge from hibernation in late-January, workers appear in early-March, and males emerge in April. Colonies dissolve in late-October, with only the new queens surviving. Willows, coyote brush, and ceanothus were seen at the study sites and are a food source for this species. Little is known about this species in San Luis Obispo County. Most CNDDB records are from collections made from the 1940s through the mid-1970s, and the locality information from these collections mostly is imprecise. The San Luis Obispo pyrg (Pyrgulopsis taylori) is an aquatic snail that has no specific listing but considered sensitive by the CNDDB. This species inhabits freshwater habitats, but individuals have also been observed on rocks and in leaf litter (CDFW 2020a). This species has been recorded nearby in Brizziolari and Chorro creeks (CDFW 2020a). Potentially suitable habitat may be present in the onsite drainage.

This species occurs in a variety of habitats as long as there is soil moisture and cover, including beach dunes, chaparral, pine forest, oak woodland, riparian forest and scrub, coastal scrub and landscaped areas near residences (California Herps 2020). This species is fossorial and buries into loose soils, leaf litter, or is associated with cover objects that provide moisture (i.e., rocks, boards, and logs). They forage just beneath the surface of loose soil or in leaf litter during the morning or evening, and may be active above the surface at dusk or at night (California Herps 2020). Their peak activity near the surface is from February through May (Yasuda 2012). There are several records from the general vicinity, but only one record nearby, from Camp San Luis Obispo in 1998 (CDFW 2020a). Because they are fossorial and found near the surface during a limited time seasonally, this species is often under-reported even when common. Suitable habitat is present in the Riparian and lesser so in the Ornamental habitats onsite, where there is abundant leaf litter or other ground cover, but the clay soils may be unsuitable. The bald eagle (Haliaeetus leucocephalus) is a state Endangered species for nesting and wintering habitats and is a CDFW Fully Protected species. Their primary prey is fish, but they also feed on small mammals, amphibians, reptiles and carrion (The Cornell Lab of Ornithology 2020b). They are usually in close proximity to large bodies of water, rivers or flooded fields with large trees or other perches nearby (CDFW 2020d). They roost communally in winter in dense conifer stands away from human disturbance. Nests in large trees in stands with moderately low canopy within 1 mile of water (CDFW 2020d). There are numerous observations of this species from various locations surrounding the study area, and sightings are common along the coast and inland reservoirs (The Cornell Lab of Ornithology 2020a). Because they are relatively common year-round in this area, individuals may fly over the site and could perch or temporarily roost on the large trees. They are unlikely to nest or communally roost due to the urban environment surrounding the site and the distance from water. The burrowing owl (Athene cunicularia) is listed by CDFW as a Species of Special Concern for burrowing sites and some wintering sites. It forages in grasslands and nests in burrows constructed by other species (typically ground squirrel) within grassland habitat. This species prefers areas with low vegetation and small hills that provide a vantage point of the surrounding area. Coastal and Salinas Valley populations in San Luis Obispo County are considered to no longer breed in this area, but they occur infrequently during the winter (Wilkerson and Siegel 2010). The species has been recorded at Camp San Luis Obispo (CDFW 2020a), CalPoly, and several other locations along Hwy. 1 (The Cornell Lab of Ornithology 2020a). Records of this species from around San Luis Obispo are from October through the end of March (The Cornell Lab of Ornithology 2020a). Potentially suitable foraging habitat is present in grassland areas onsite. A small colony of California ground squirrel burrows that could be used by owls was observed onsite. This species is not expected to nest onsite but could occur as an uncommon transient moving through the area during the winter. The California horned lark (Eremophila alpestris actia) is on the CDFW Watch List. It occurs in open habitats such as agricultural areas and grassland, and prefers areas with sparse vegetation or patches of bare ground. Nests are placed on the ground in open areas, sparse vegetation, or next to a grass clump or other object (Audubon 2020). This species has been recorded on Camp San Luis Obispo (CDFW 2020a), and there are several observations from the general area near the property (The Cornell Lab of Ornithology 2020a). Therefore, this species could occur within Annual Grassland habitats onsite on a regular or transitory basis and could nest onsite. Page 192 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 21 Cooper's hawk (Accipiter cooperii) is on the CDFW Watch List for nesting. This is a woodland species that prefers dense stands of coast live oak, riparian forest, and mixed coniferous forests near a source of water. They prey on birds, small mammals, reptiles and amphibians. They have been documented in numerous locations at CalPoly, on the east side of Bishop Peak, and throughout the residential areas surrounding the site (The Cornell Lab of Ornithology 2020a). The dense Riparian and Ornamental habitats onsite would be suitable for foraging and nesting. The ferruginous hawk (Buteo regalis) is on the CDFW Watch List for wintering sites, and it occurs in this area during the winter. They use lower elevation open grassland habitats, and also occur in sagebrush, desert scrub, and edges of pinyon-juniper (CDFW 2020d). Roosting is in open areas on a lone tree or utility pole. They prey on rabbits, ground squirrels, mice, amphibians and reptiles (CDFW 2020d). There are several observations from open grassland habitats surrounding the site, such as at CalPoly, along Highway 1, and O'Connor Way (The Cornell Lab of Ornithology 2020a), and wintering has been documented nearby (CDFW 2020a). Individuals could forage periodically onsite in the Annual Grassland habitat and perch or roost in the Riparian or Ornamental habitats, but they do not nest in this area. They could potentially use the site for wintering. The golden eagle (Aquila chrysaetos) is considered a Fully Protected species by CDFW and is on the Watch List for nesting and wintering. Nesting is on cliffs, large trees or other structures such as electrical towers. There are numerous records from Heritage Ranch and along the Salinas River (The Cornell Lab of Ornithology 2020a). This species forages over a variety of open habitats, and could forage in Annual Grassland or fly over the site. Large eucalyptus and coast redwood trees may have sufficient structure for nesting, but due to the proximity of human activity, they are unlikely to nest on the property. The grasshopper sparrow (Ammodramus savannarum) is a CDFW Species of Special Concern that occurs almost exclusively in grassland habitats. Other types of open habitats with patches of bare ground and little shrub cover, such as pastures and agricultural fields, may also be used (The Cornell Lab of Ornithology 2020b). They nest on the ground at the base of clumps of grass. The prey on grasshoppers and other invertebrates, where there are patches of bare ground (The Cornell Lab of Ornithology 2020b). This species has been recorded at numerous locations surrounding the site (The Cornell Lab of Ornithology 2020a). Suitable habitat is present in Annual Grassland onsite, and the species could occur year-round foraging and nesting. The great blue heron (Ardea herodias) does not have a specific listing status but is considered a sensitive species by CDFW for nesting colonies, which are located in forests near bodies of water. This species is associated with wetland habitats, but it is occasionally seen foraging in grasslands or agricultural fields away from water. Nesting colonies are near aquatic habitats, where they nest mainly in large trees. There are numerous observations of great blue herons from nearby CalPoly agricultural lands as well as urban areas within the city (The Cornell Lab of Ornithology 2020a). Individuals could occur onsite periodically while foraging, but nesting colonies would not utilize the site due to the distance from any lakes, ponds or wetlands. Appropriate aquatic habitat for nesting colonies is not present in or near the study area. The great egret (Ardea alba) does not have a specific listing status, but is considered sensitive by the CNDDB for nesting colonies. This species does not nest in this area. Individuals forage in aquatic habitats, including freshwater and saline emergent wetlands, estuaries, lakes, streams, ditches, and mudflats, where they prey on fish and crustaceans. They also forage in fields on small mammals, amphibians and reptiles. They roost communally in trees near foraging areas (CDFW 2020d). This species has been recorded at numerous locations close to the site, including parks and Page 193 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 22 other patches of habitat within urban San Luis Obispo (The Cornell Lab of Ornithology 2020a). There is a chance that transient individuals could forage periodically onsite in the Annual Grassland habitat, but there is insufficient aquatic habitat to support communal roosting of this species. No nesting would occur. The loggerhead shrike (Lanius ludovicianus) is a CDFW Species of Special Concern for nesting. This species occurs in variety of relatively open habitats with low vegetation and well-spaced shrubs or trees, such as coastal scrub, grasslands, agricultural fields, pastures, riparian areas, desert scrub, savannas, prairies, golf courses, and along roadsides. They prefer areas where there are objects to perch on such as fences, trees or shrubs (Audubon 2020). Nests are placed in dense and sometimes thorny trees or shrubs and brush piles (Audubon 2020). They prey on insects, amphibians, reptiles and small mammals, and may impale their prey on sharp objects. There are observations of this species near the study area at CalPoly, within urban San Luis Obispo, and at Camp San Luis (The Cornell Lab of Ornithology 2020a). Suitable foraging habitat is present throughout the Annual Grassland, Riparian and Ornamental habitats for this species. They could build nests in the dense shrubby Ornamental or Riparian areas. The merlin (Falco columbarius) is on the CDFW Watch List for wintering. They are a small falcon that preys on songbirds and shorebirds (The Cornell Lab of Ornithology 2020b), and also small mammals and insects (CDFW 2020d). They occur in this area in winter, when they occupy coastal areas, grasslands, savannahs, woodlands, lakes, wetlands, and edges of coniferous forest (CDFW 2020d). They have been recorded on CalPoly and in downtown San Luis Obispo (The Cornell Lab of Ornithology 2020a). They could forage onsite in the Annual Grassland habitat or occur as a transient, but they do not nest in this area. The northern harrier (Circus cyaneus) is a CDFW Species of Special Concern for nesting. This species prefers wide open country with wetlands but they also occur in rolling grasslands or desert shrubland. Nests are placed on the ground in dense clumps of vegetation, usually in marshes, but occasionally they nest in dry open fields (Audubon 2020). There are numerous observations from the surrounding area, including CalPoly, urban areas in San Luis Obispo, and Laguna Lake (The Cornell Lab of Ornithology 2020a). They could occur onsite occasionally while foraging or flying over, but are unlikely to nest in the study area due to the urban environment surrounding the site. The prairie falcon (Falco mexicanus) is on the CDFW Watch List for nesting. This species forages in open grasslands, scrublands, and agricultural areas including feed lots. Nesting habitat is generally rock formations and large trees, but they also occur in urban areas and nest high on buildings. This species has been recorded at several locations on CalPoly and around the edge of the San Luis Obispo urban area (The Cornell Lab of Ornithology 2020a). They could forage in the Annual Grassland habitat, and potentially could nest in the tall eucalyptus or coast redwoods. The sharp-shinned hawk (Accipiter striatus) is on the CDFW Watch List for nesting. This species generally occurs in densely forested coniferous forests, mixed woodlands and riparian habitats, and dense forest is required for nesting. During migration, it uses coastlines, lake shores and mountain ridges (Audubon 2020). It does not breed in San Luis Obispo County. There are numerous observations of this species from surrounding the site, including three records from the adjacent neighborhood, CalPoly and urban San Luis Obispo (The Cornell Lab of Ornithology 2020a). This species could occur onsite during migration and could periodically forage onsite, but does not nest in this area. The Riparian and Ornamental areas onsite are suitable for foraging. Page 194 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 23 The snowy egret (Egretta thula) is considered sensitive by the CNDDB for nesting colonies, but does not have a specific listing status. This species does not nest in the county. They occur in inland portions of the county during migration, in which they can be found in wetlands, ponds, rivers, irrigation ditches and agricultural fields. Along the coast they remain longer into the year, occurring in estuaries, and coastal freshwater and saline wetlands. They feed along shallow margins on fish, crustaceans, insects, amphibians, reptiles, worms, snails and small mammals. They roost in dense emergent wetland vegetation and trees near water (CDFW 2020d). . There are only a few records nearby at CalPoly, but they are more commonly reported near wetland habitats nearby such as Laguna Lake and western Foothill Road (The Cornell Lab of Ornithology 2020a). This species could forage in winter in the Annual Grassland onsite, but would not nest in this area. The tricolored blackbird (Agelaius tricolor) is a state Threatened species and a CDFW Species of Special Concern for nesting colonies. This species nests and roosts colonially in freshwater marshes with dense tules, cattails, or blackberry thickets. They forage in areas with low-growing vegetation such as agricultural fields, grasslands and feedlots. Wintering tricolored blackbirds congregate in large multispecies flocks, often containing red-winged blackbirds (The Tricolored Blackbird Working Group 2007). Nesting colonies have been recorded at several ponds along Highway 1 (CDFW 2020a), and there are numerous observations on CalPoly agricultural lands (The Cornell Lab of Ornithology 2020a) near the site. No suitable water sources are present onsite for breeding habitat, but individuals may forage periodically within the Annual Grassland or occur as transients. The white-tailed kite (Elanus leucurus) is a CDFW Fully Protected species for nesting sites. This species prefers open areas for foraging, including grasslands, river valleys, oak savanna, agricultural areas, deserts, and marshes (Audubon 2020). They nest in large isolated trees, and occasionally in riparian habitats (CDFW 2020d). During the non-breeding season, they roost communally in trees or tall shrubs at the edges of grasslands (The Cornell Lab of Ornithology 2020b). This species has been recorded at several locations close to the property on CalPoly agricultural lands, as well as the urban area of San Luis Obispo (The Cornell Lab of Ornithology 2020a). They could forage in the Annual Grassland habitat, and roost or nest in the Riparian or Ornamental habitats onsite. The yellow-billed magpie is endemic to California (i.e., its range is limited to California), and it is a non-migratory, permanent resident. It inhabits open oak woodland and savannah, riparian, and valley hardwood-conifer. It also occurs in human-modified habitats such as residential and agricultural areas, pastures and orchards. Feed on the ground on insects, invertebrates, trash, carrion, acorns, fruit, grain, nestlings, eggs, earthworms, ticks and live rodents (CDFW 2020d). They nest in small colonies, building stick nests at the tops of trees (Audubon 2020). Shortly before sunset, magpies aggregate and move to a communal roost site in which they spend the night. Nesting and communal roost sites are considered sensitive by CDFW (2019). Individuals have been recorded at several locations near the study area, including CalPoly, Camp San Luis and parks in urban San Luis Obispo, but no communal roosts are documented in this area (The Cornell Lab of Ornithology 2020a). They are generally more common north of Cuesta Grade, but do extend along the coast and have frequently been sighted in Morro Bay. All of the habitat types onsite are suitable for this species, and they could occur as transients or regular visitors, foraging and perching on trees. The yellow warbler (Setophaga petechia) is a CDFW Species of Special Concern for nesting. In California, this species breeds along coastal areas from Del Norte County south to Ventura County, where it prefers medium-density riparian woodlands (CDFW 2020d). This is a migratory species Page 195 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 24 that occurs in this area only during the breeding season. This species is closely tied to riparian habitat for foraging and nesting, but they also use residential areas and orchards. There are several records of this species from along San Luis Creek in downtown, Cal Poly, Camp San Luis and at a residence in the neighborhood surrounding the site (The Cornell Lab of Ornithology 2020a). The Riparian and Ornamental trees and shrubs onsite are suitable for this species, and they could forage or nest onsite. The pallid bat (Antrozous pallidus) is a CDFW Species of Special Concern. This species forages in a variety of dry, open habitats such as grassland, deserts, woodland, shrubland and coniferous forest. Maternity and winter roosting sites are cavities or caves in rock features, large trees or buildings, and these structures must substantially moderate temperature. Day roosts are in caves, crevasses, mines and occasionally hollow trees or buildings. Night roosts are in more open areas such as porches or agricultural buildings. They forage on beetles, moths, spiders, scorpions and Jerusalem crickets (CDFW 2020d). There are records of the species from the vicinity, including Camp San Luis Obispo and the tunnel for San Luis Creek within the city (CDFW 2020a). They could forage over the site and night roost in the outbuildings or open garage. There is a slight possibility they could day roost in the large eucalyptus and/or coast redwoods. The San Diego desert woodrat (Neotoma lepida intermedia) is a CDFW Species of Special Concern. It is present in a variety of habitats, preferring rock outcrops and rocky slopes with moderate to dense canopies. This species is found in disjunct areas throughout the state, and occurs throughout San Luis Obispo County (CDFW 2020d). They build stick houses or middens, usually against a rock crevice or the lower branches of trees, which are used for nesting, food caching and escape from predators. They eat buds, fruits, seeds, bark, leaves (CDFW 2020d). This species has been documented at Cerro San Luis Obispo (City of San Luis Obispo 2005) and on lands near Diablo Canyon Nuclear Power Plant (CDFW 2020a). Woodrat middens were observed onsite during the surveys, and could be that of the San Diego desert woodrat or the big-eared woodrat (Neotoma macrotis macrotis). There is only one very small rock outcrop onsite, but suitable rocky habitat is present nearby on Bishop Peak. The Riparian habitat onsite is marginally suitable because they prefer shrubland habitats. There are plentiful food resources in the Ornamental habitat. Townsend's big-eared bat (Corynorhinus townsendii) is a CDFW Species of Special Concern. This species occurs in a variety of habitats, including dry upland areas, semidesert, coniferous forest, and riparian woodland. They prefer foraging along the edges of riparian vegetation and they drink water from ponds. They roost in caves, mines, abandoned buildings and under bridges (Gruver and Keinath 2006). They are considered to widespread throughout California except for high elevations in the Sierra Nevada and occur in this area throughout the year (CDFW 2020d). There are records or roost sites on Camp San Luis Obispo and along Chorro Creek (CDFW 2020a). The rocky areas of nearby Bishop Peak may also be suitable for roosting. This species could forage over the site where there is suitable Riparian bordered by Annual Grassland, but there is no suitable habitat for roosting. The outbuildings onsite would not be suitable because of frequent human disturbance. The western mastiff bat (Eumops perotis californicus) is a CDFW Species of Special Concern. It occurs in coniferous and deciduous woodlands, coastal scrub, grasslands, chaparral, deserts and urban areas (CDFW 2020d). This species is resident year-round in the Coast Ranges, and are active nocturnally throughout the year. They roost in cliff faces, tunnels, on buildings or in trees. Maternity roosts are restricted to crevices in rock formations or buildings (CDFW 2020d). There is a record in the CNDDB from the general area of San Luis Obispo (CDFW 2020a). This species could forage over all areas of the property. They could roost in the large trees onsite or in the outbuildings or garage.

Riparian habitats are also considered to be sensitive biological resources by the City and CDFW. Within several small openings within the Riparian were farm road crossings, and beyond the extent of the Riparian canopy to the north and extending offsite, the drainage has herbaceous wetland species that align with the Freshwater Seep community, which has a State Rarity Rank of S3.2. Species observed in this community included common spikerush, brown -headed rush, tall flatsedge, and curly dock, which integrated with Annual Grassland on the slopes of the drainage. A small pool of water was present along the northern property boundary, and damp soil conditions were present along the bottom of the drainage, during the March 4th survey, which was during a prolonged period without rainfall. Therefore, the source of water appears to be surfacing groundwater in the headwater areas of the drainage, instead of from recent rainfall, and this distinction is one factor that separates Freshwater Seep communities from Vernal Marsh (Appendix E). The Annual Grassland was considered to fall under the Wild Oats and Annual Brome Grasslands association, which is a semi-natural alliance and is not considered sensitive (CDFW 2020b). The low density of purple needlegrass was not considered to fall under the classification of Valley Needlegrass Grassland, as described in Section 3.4.4. Certain Rock Outcrops can be considered to be significant features of local concern, but the Rock Outcrop onsite was small in size, was not serpentinite and does not provide any significant habitat value. See Appendix E and Figure 7 for information on other sensitive natural communities known to occur in the vicinity, but that do not occur onsite. 3.6.4 Designated Critical Habitat The study area occurs within designated critical habitat for the California red-legged frog (Figure 7). This area is Unit SLO-3 Willow and Torro Creeks to San Luis Obispo, and comprises approximately 116,517 acres (USFWS 2010). The unit occurs along the coast of central San Luis Obispo County, north of Morro Bay, and extends eastward to include the northern portion of the City of San Luis Obispo and areas east of the city. It provides connectivity within and between the inner Coast Range and the Santa Lucia Range. The unit contains features that are essential for the conservation of the species, including: 1) permanent and ephemeral aquatic breeding habitat; 2) non-breeding aquatic and riparian habitat; 3) upland habitat; and 4) dispersal habitat (USFWS 2010). The study site does not provide suitable aquatic breeding habitat for the California red-legged frog. The onsite drainage is too ephemeral, and does not contain water of sufficient depth long enough for California red-legged frog larvae to complete metamorphosis. The stream lacks any significant pools, and is also of insufficient depth to support adult frogs, which dive into the water to escape predators and are associated with water depths of at least 2.3 feet deep (Hayes and Jennings 1989). The riparian habitat and mesic conditions along the stream corridor could potentially be used by juvenile frogs dispersing away from breeding ponds, if there were such sites adjacent to the property. Based on aerial photograph review, it does not appear that potential breeding ponds are nearby. The Annual Grassland and Ornamental habitats onsite would be considered to be suitable upland and dispersal habitats for the frog. The designated critical habitat ruling considers upland areas within 1 mile (1.6 kilometers) within suitable aquatic habitats to be essential for shelter, foraging, predator avoidance, and maintaining the environmental conditions supporting the aquatic habitat. Upland and riparian habitat within 1 mile of occupied or previously occupied aquatic sites Page 197 of 1225 ^_ San Luis Obispo Atascadero Lopez Mountain Pismo Beach Santa Margarita Arroyo Grande NEPort San Luis Copyright:© 2013 National Geographic Society, i-cubed 1 inch = 1.5 miles.

The CNDDB contains an historic record of the California red-legged frog 0.4 mile from the study area at Brizziolari Creek, which is separated from the site by Highway 1. The next closest record to the study area is Chorro Creek at Camp San Luis Obispo, at 1.8 miles away, also on the opposite side of Highway 1. The highway would be considered to be a barrier to dispersal where there is a concrete median and high degree of traffic may otherwise prevent any successful movement. Two potentially suitable ponds are seen on aerial photography within one (1) mile of the site, on the same side of Highway 1 and with a contiguous stretch of undeveloped grassland in between. The species has not been documented from these ponds, but the potential exists for them to occur. Nevertheless, the study area does not provide linkage to any other suitable aquatic sites and is surrounded on three sides by dense urban development. Therefore, the site could be considered to have very low potential for non-breeding, upland and dispersal habitat for the frog within the designated habitat area. 3.6.5 Migratory Birds and Raptors There are numerous bird species with potential to occur at the site that could nest in the onsite Riparian and Ornamental habitat types. In addition to the special-status bird species described above, avian species that could nest onsite also include raptors protected under California Fish and Game Code, the Bald and Golden Eagle Protection Act, and common species that are protected under the MBTA. 4.0 IMPACT ANALYSIS AND RECOMMENDED MITIGATION The following impact analysis and recommended mitigation measures are intended to help guide project planning efforts and support the CEQA review process. The impact discussion addresses the range of impacts that could result from implementation of the proposed project. Direct effects (or impacts), as defined under CEQA, are caused by a project and occur at the same time and place. Indirect effects are caused by a project, but occur at a different time or place. Cumulative effects are those that result from when the effects of the subject project combine with effects from other unrelated projects to compound environmental harm. Our understanding of the extent of proposed development footprint, along with the observations of onsite conditions from the site visit and desktop evaluation of special-status biological resources in the project vicinity, provided the basis for this analysis. Impact statements defining potential impacts on biological resources and proposed mitigation measures to reduce project-related impacts are described. 4.1 Direct and Indirect Effects The impact area for the proposed subdivision would occur mainly in the Developed/Ruderal and Ornamental land uses associated with an existing residence. Annual Grassland that has been grazed also occur in the development footprint. Numerous trees, as well as various shrub species, planted in landscaped and ornamental areas would be removed as shown on project plans. Non- native trees such as silver wattle and eucalyptus, along the edge of the Riparian habitat would be removed, while native oaks, willows and other riparian species would be protected. A 20-foot setback has been designated from the top of bank or outer edge of riparian, whichever is farther. Selective grading is proposed within the creek setback to create side slopes needed for the level building pads and install underground stormwater treatment and retention areas. There is also an outfall and associated rip rap pad proposed to tie in a stormwater retention area to the creek. Occurrences of a rare plant species, Cambria morning glory, would be removed, and the project plans include compensatory mitigation sites for this species within the creek setback area. Page 199 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 28 There is potential for direct effects on wildlife species during the removal of trees and other vegetation, during site grading and other construction activities, as described in Section 4.1.1 below. Potential also exists for indirect effects on the Riparian habitat onsite and habitats and associated species located downstream from the site, through surface runoff over disturbed areas during or after construction. Each of these potential effects is discussed in the sections following. 4.1.1 Adverse Effects on Candidate, Sensitive or Special-status Species Focused rare plant surveys were conducted within the blooming period of the special-status species determined to have potential to occur onsite during the background review. One of these species, the Cambria morning-glory, was observed in four distinct occurrences onsite. Two trees, southern California black walnut and Monterey pine were also identified onsite and determined to not meet the rarity threshold since they were planted ornamental species outside their normal range. The two walnut trees observed along the creek appeared to have been young recruits from historic plantings onsite or in the immediate area. The project would result in the loss of all four morning glory occurrences totaling approximately 1,076 square feet. Although Cambria morning- glory is relatively common in the region, it is considered sensitive with a CRPR of 4.2, which is a watch list for species of limited distribution that are moderately threatened. Approximately 300 plants were located in four occurrences in Annual Grassland habitat in the western portion of the property. CDFW recommends that Rank 4 species be evaluated under CEQA, and if the species is regionally rare or unique, it must be fully analyzed in a CEQA document. The level of significance of effects is to be based on: • The type locality of a California Rare Plant Rank 4 taxon; • Occurrences at the periphery of a species’ range; • Areas where the taxon is especially uncommon; • Areas where the taxon has sustained heavy losses (declining); • Occurrences exhibiting unusual morphology or occurring on unusual substrates; • Species maintained on Bureau of Land Management (BLM), USFWS, or U.S. Forest Service (USFS) sensitive species lists; and • Taxa associated with a habitat that is declining in California at a significant rate (CNPS 2020b). None of these conditions apply to this particular species within the local area because numerous records of the species were identified in the CNDDB search (Figure 5) and the site is located within the center of the species' local distribution (Calflora 2020). This species is only found in the Central Coast region, but it is a common associate of coastal grasslands from San Luis Obispo west to Los Osos and north to San Simeon. The Annual Grassland habitat in which this species was found onsite is common in the region, and the individuals onsite did not have unusual morphology. Although mitigation for this species may not be required due to the low level of local rarity, compensatory mitigation areas have been proposed on the site plans and a conceptual mitigation program is described below to maintain its presence on the subject property post-development of the proposed subdivision. No other special-status plant species evaluated in Appendix E are expected to occur on the site, and no further surveys are recommended. There would be no measurable negative effect on wildlife habitat because the less than 5 acres of developed rural residential lands that would be lost are only marginally suitable for wildlife species and the Riparian habitat and corridor would be maintained and enhanced (as described below in Section 4.1.2). The potential for direct project effects on individuals of special-status wildlife Page 200 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 29 species varies based on the timing of the initiation of construction activities with the manner in which these species may utilize the site. Individuals of special-status species that use the site on a transitory basis and are mobile, such as foraging monarch butterflies, obscure bumble bees, birds and bats, are expected to move away from any temporary disturbance during construction activities and would not be directly affected. Similarly, birds and raptors that could temporarily roost in the trees also would not be affected because they would naturally relocate, and roosting habitat will be preserved and enhanced. Species that would only use the site for foraging and that do not breed in this area or in which suitable breeding habitat is not present would not be affected by the project include: bald eagle, ferruginous hawk, golden eagle, great blue heron, great egret, merlin, northern harrier, sharp-shinned hawk, snowy egret, tricolored blackbird and yellow-billed magpie. The San Luis Obispo pyrg, if it were present onsite, would be limited to the immediate creek corridor, and no construction would occur in this habitat Mitigation to protect the creek habitat from indirect effects of sedimentation and pollutants are described below in Mitigation Measure BIO-5. However, many of the special-status bird species listed in Appendix E could use the large trees and shrubs in the Riparian and Ornamental habitats for nesting, and others (e.g., California horned lark and grasshopper sparrow) could nest in the Annual Grassland habitat. If construction activities were initiated during the nesting season, significant effects on special-status bird species could occur. Wintering burrowing owls could occur onsite in burrows of ground squirrels and could be impacted by grading activities conducted during the winter, but are not present in this region during the summer. Individuals of less mobile species such as the northern California legless lizard and nest sites of the San Diego desert woodrat may be affected at any time of year. Bat species could roost in the non-native trees in Ornamental or Riparian areas or in the structures that would be removed, and disturbance to roost sites could be considered to be significant under CEQA. Project impacts on these species are described in further detail below and mitigation is prescribed. Designated critical habitat for the California red-legged frog is present at the project site. No suitable aquatic habitat is present on the site, and would only represent marginal upland and dispersal habitat. However, no known populations are within 1.0 mile of the site that are not separated from it by barriers to dispersal (i.e., Highway 1 and urban development). The site would be considered to have very low potential for non-breeding, upland and dispersal habitat for the frog. Therefore, the loss of less than five (5) acres within designated critical habitat is not expected to be significant from a biological resources perspective or pursuant CEQA. This determination also considers that the Riparian corridor and the required setback will be preserved and enhanced under the project, and could potentially be used by the frog for dispersal should any populations occur nearby that have not yet been documented. The Riparian habitat would provide suitable habitat to support a dispersal corridor from one end of the site to the other. Because there would be no significant effects on California red-legged frog critical habitat, no mitigation is needed. In addition to the special-status bird species identified with potential to nest onsite (Appendix E), other avian species protected under the MBTA and California Fish and Game Code could also be affected. If construction takes place during the nesting season, these activities could result in the mortality of eggs or young reliant on the nest, or disturbance from construction activities could potentially disrupt nesting behavior of avian species in adjacent areas. Project effects on active bird nests would potentially be significant, and mitigation is required as described below. Impact BIO-1. Construction of the project will impact occurrences of the Cambria morning- glory. This is a significant but mitigable impact. The proposed disturbance footprint on the subject property would impact small occurrences of Page 201 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 30 Cambria morning-glory that total 1,076 square feet (Figure 3 and project plans). Cambria morning- glory is a CRPR 4.2 species, which is a watch list, and the project will not adversely affect or jeopardize the continued existence of this species in the project area; therefore, a rigorous mitigation and monitoring program is not warranted. To ensure impacts on special-status plant species on the subject property remain below the significance threshold under CEQA, Mitigation Measures BIO-1a and -1b are required. Mitigation Measure BIO-1a: Implement a Rare Plant Mitigation Program that ensures no net loss of Cambria morning-glory on the project site. A Rare Plant Mitigation Program shall be implemented for Cambria morning-glory, and shall be overseen by a qualified botanist approved by the City. As a component of the program, seed shall be collected from Cambria morning-glory plants during the appropriate season prior to grading activities. Using standard procedures, the qualified botanist shall clean and store the seeds until the receiving sites shown on the project plans are ready. Suitable habitat outside of the development area (as designated on the site plans in the creek setback zone) shall be designated as the mitigation site that will be maintained in a natural state and not be subject to mowing earlier than June 1st each year. The areas will be maintained as grassland habitat and no planting ornamental species or other adverse modifications will be allowed. The mitigation site shown on the project plans is twice the size as the areas currently occupied by the rare plant occurrences. This equates to a 2:1 mitigation ratio (habitat created to habitat impacted) to ensure a minimum 1:1 replacement ratio is achieved. Top soil from each of the four occurrences will be collected in six (6) inch lifts and stored for top-dressing the mitigation site once grading of the pads is complete. As needed, the mitigation site should be prepared for planting by removal of non-native species or other measures as necessary, then applying the salvaged topsoil. Once topsoil has been layered evenly through the area, collected seed should be hand- broadcasted into suitable locations by the qualified botanist and covered with compost. Seed may also be incorporated into the native erosion control seed mix described in Table 1 under Mitigation Measure BIO-5 and applied to other grassy areas of the site as part of the erosion control effort. Depending on the season when construction starts, the qualified botanist may also potentially salvage plants (i.e., dig them up when soils are moist) and transplant them to containers to be maintained until the mitigation sites are ready for planting. Mitigation Measure BIO-1b: Conduct annual monitoring and implement adaptive management measures for five years to ensure no net loss of Cambria morning-glory onsite. The Rare Plant Mitigation Program shall include annual monitoring and maintenance of the mitigation site to ensure success of the program. Monitoring by a qualified botanist should occur during the spring growing season (between April 15 and May 15 each year) to ensure successful establishment of planted propagules. The established rare plants should be mapped to evaluate the goal of no net loss of the species onsite. The measurable objective should be to have at least 1,076 square feet of occurrence comprised of approximately 300 Cambria morning-glory plants. Appropriate vegetation sampling techniques should be used to assess the areal cover of vegetation to evaluate the status of the established occurrences. If the success criteria of having approximately 300 plants covering 1,076 square feet within the creek setback zone is not reached by the third year of monitoring, remedial actions such as collecting more seed and distributing it in suitable areas should be employed, with a corresponding additional year of monitoring. Other activities to increase the success of the rare plant mitigation effort could include non-native plant species removal within the mitigation site to reduce competition, additional seed application, or supplemental irrigation during periods of prolonged drought. The qualified botanist would prepare annual reports for the applicant detailing the methods and results of the mitigation effort and monitoring effort. The applicant would be responsible for submitting the report to the City on an Page 202 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 31 annual basis (by December 31st of each year) for the five-year monitoring period or until the final success criteria described above are met. Implementation of these mitigation measures would reduce project effects on special-status plant species to a level below significance. Impact Bio-2. Construction of the project could potentially impact special-status animal species. This is a significant but mitigable impact. Burrowing owls could occupy burrows in the Annual Grassland habitat during the winter, and could be injured or killed by grading activities. Northern California legless lizards could occur in leaf litter, mulch, or under objects in the Developed and landscaped areas of the site that will be graded, and killed during initial phases of the project. They could also occur in the Riparian habitat where acacia trees will be removed, or where soils may be prepared for restoration activities. San Diego desert woodrats may occupy middens in the more densely vegetated Ornamental habitats, which will be eliminated. Bats may roost in the structures onsite or in the large trees, and may be harmed when these substrates are removed. Mitigation is required to avoid and minimize project effects on these species, and general measures are described below. None of these species are federally listed; thus, formal consultation with USFWS would not be needed. They are protected by CDFW, and if found on the site in areas that cannot be avoided, CDFW shall be consulted to refine the measures used to ensure individuals are not harmed by the work. Mitigation Measure BIO-2a: If possible, avoid initial site grading in the winter months. The burrowing owl has been recorded in the vicinity of the project from October to the end of April. If initial vegetation removal and site grading is conducted outside of this period, potential effects on this species would be avoided and no further mitigation would be required. Restricting the time period for earth-moving activities is also recommended to avoid or minimize the potential for erosion and sedimentation (see Mitigation Measure BIO-5). If initial grading work must commence during the time period that burrowing owls may be present onsite, preconstruction surveys this species shall be included in the survey effort described in Mitigation Measure BIO-2b. Mitigation Measure BIO-2b: Conduct a preconstruction survey and avoid construction in areas occupied by special-status wildlife species until relocated or they have left the site. Within seven days prior to the start of vegetation/tree removal, ground-disturbing activities, or demolition of existing structures, a biologist approved by the City shall survey the project impact area. A separate survey shall be conducted for any phase of the project not conducted concurrently (i.e., structure demolition conducted prior to general site grading). The biologist shall use appropriate survey techniques for the special-status species identified in this BRA as having potential to occur onsite. For example, burrows shall be examined with binoculars or wildlife cameras, and inspected for whitewash or prey remains. Leaf litter and cover objects shall be searched for northern California legless lizards. Visual surveys should be conducted for woodrat middens, both on the ground and in trees. If any are found, they should be monitored such as through the use of wildlife cameras to determine whether they are active. Potential bat roost sites shall be inspected for sign of roosting bats such as guano or prey remains. If any of these species are found onsite, the biologist shall coordinate with the City, and CDFW as appropriate, on methods to ensure the successful relocation of individuals to suitable habitat nearby. In some cases, CDFW may recommend creating structures for displaced woodrats and bats. Burrowing owls can be discouraged from using burrows onsite, or occupied burrows can be avoided until the owls have left the area. Bats can be restricted from roost sites by placing netting over their entrances after they have left the roost for night-time foraging. The wildlife protection measures to be employed will be based on the results of the Page 203 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 32 survey and the particular characteristics of their use of the site, in coordination with CDFW and the construction engineer. If no special-status animal species are found onsite during the preconstruction survey, work may proceed with the implementation of the following Mitigation Measures BIO-2c through -2e. Mitigation Measure BIO-2c: Prepare and present a Worker Environmental Awareness Program. A qualified biologist shall prepare a Worker Environmental Awareness Program that will be presented to all project personnel. This program shall detail measures to avoid and minimize impacts on biological resources. It shall include a description of special-status species potentially occurring on the project site and their natural history; the status of the species and their protection under environmental laws and regulations; and, the penalties for take. Recommendations shall be given as to actions to avoid take should a special-status species be found on the project site. Other aspects of the training shall include a description of general measures to protect wildlife, including: • Delineation of the allowable work area, staging areas, access points and limits to vehicle access; • Storage of all pipes, metal tubing, or similar materials stored or stacked on the project site for one or more overnight periods shall be either securely capped before storage or thoroughly inspected for wildlife before the materials are moved, buried, capped, or otherwise used. • Inspected of materials stored onsite, such as lumber, plywood, and rolls of silt fence, for wildlife that may have sheltered under or within the materials; • Use of netting to exclude birds from nesting in construction materials; • Constructing escape ramps in all excavations and trenches more than 6-inches deep; • Contact information for the City-approved biologist and instructions should any wildlife species be detected in the work site; • Dust suppression methods during construction activities when necessary to meet air quality standards and protect biological resources; and • Methods for containment of food-related trash items (e.g., wrappers, cans, bottles, food scraps), small construction debris (e.g., nails, bits of metal and plastic), and other human- generated debris (e.g., cigarette butts) in animal-proof containers and removal from the site on a weekly basis. All project personnel who have attended the training shall sign an attendance sheet. The program shall be repeated for any new crews that arrive subsequently on the site. Mitigation Measure BIO-2d: Install high-visibility construction and silt fence along the creek corridor to delineate the allowable work area, exclude wildlife from the site, and protect the stream habitat. After the site has been cleared of all vegetation and structures that could provide refugia for wildlife, a high-visibility construction fence at least 4-foot tall together with a silt fence, or an approved wildlife exclusion fence, shall be erected along the creek corridor to delineate the limits of grading and vehicle access. If possible, the fence shall be erected along the creek setback line, but where grading is needed within the setback area to create the building pads, encroachment into the setback shall be kept at a minimum. In no case shall ground disturbance occur within the Riparian habitat or below the top of bank without obtaining proper permits from regulatory agencies (see Section 4.1.2). The type of fence used may be a combination of wildlife exclusion and silt fence (i.e., ERTEC Triple-function E-fence) or similar materials that would serve the purposes of safety/construction area delineation, wildlife exclusion, and siltation prevention. The fence shall be checked weekly by construction personnel for needed maintenance. Page 204 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 33 Mitigation Measure BIO-2e: Conduct biological monitoring for special-status wildlife species while the property is cleared and graded and structures are removed. A qualified biologist shall monitor the removal of structures, materials and vegetation that may provide cover northern California legless lizards and bat roosting sites. The biologist shall be onsite daily until all materials are removed and all vegetation has been cleared. If any special-status species are found, work shall be delayed until the individuals have left the work area or CDFW shall be notified to obtain authorization for capture and relocation. If none are found during monitoring, work may proceed. Implementation of these mitigation measures would reduce project effects on special-status wildlife species to a level below significance. Impact Bio-3. Construction activities could potentially directly impact nesting of special- status avian species as well as bird species protected under the Migratory Bird Treaty Act and California Fish and Game Code. This is a significant but mitigable impact. If construction activities take place during the nesting season (February 1 to August 31), nesting behavior could be disrupted and construction disturbance could cause adults to abandon nests containing eggs or young. Nesting birds that are protected under the MBTA and special-status species could potentially nest in the Ornamental or Developed areas, and Annual Grassland habitat, within the impact area. Additionally, birds could nest in the Riparian habitat adjacent to the work area and may be in close enough proximity that construction activities may affect their behavior. To reduce potential project impacts to a level below significance, Mitigation Measures BIO-4 is required. This assumes that the seasonal restriction for the initiation of construction described under Mitigation Measure BIO-2a would be followed, which may place the activities within the nesting season. If construction commences outside of the nesting season (September 1 to January 31), no mitigation for nesting birds would be needed. Mitigation Measure BIO-3: Conduct a preconstruction nesting bird survey and avoid active nests. A qualified biologist shall conduct a preconstruction survey for nesting birds within all areas of the property. The preconstruction survey shall be conducted within seven days before the initiation of construction activities. During this survey, the qualified biologist shall search for birds exhibiting nesting behavior and inspect all potential nest substrates in the impact and buffer areas. Any nests identified will be monitored to determine if they are active. If no active nests are found, construction may proceed. If an active nest is found within 50 feet of the construction area, the biologist, in consultation with the City, shall determine the extent of a buffer to be established around the nest. The buffer will be delineated with flagging, and no work shall take place within the buffer area until the young have left the nest, as determined by the qualified biologist. Implementation of these mitigation measures would reduce project effects on protected nesting birds to a level below significance. 4.1.2 Adverse Effects on Riparian Habitat or Sensitive Natural Communities The Riparian habitat onsite is considered to be classified as the Central Coast Live Oak Riparian Forest community, which has a State Rarity Rank of 3.2, and as such is considered sensitive under CEQA. There was a small area of the Freshwater Seep community, which has a State Rarity Rank of S3.2, within the limits of the Riparian habitat and was outside of the project impact area. Riparian habitats are also considered to be sensitive biological resources by the City and CDFW. The extent Page 205 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 34 of the Riparian habitat onsite has been delineated (Figure 3 and project plans), and all project activities will remain outside of this area except for the installation of a rip rap pad at the downstream end of a stormwater treatment/retention area (see Appendix A). For work in this area, a wetland delineation will be needed to determine the extent of areas under the jurisdiction of USACE under Section 404 of the Clean Water Act; RWQCB under Section 401 of the Clean Water Act and Porter-Cologne Water Quality Control Act; and, CDFW pursuant to California Fish and Game Code Sections 1600 et seq. Any work conducted in jurisdictional areas would require permitting from these agencies, as described below. Permanent impacts have been designed to remain outside of the City-designated 20-foot creek setback, but temporary impacts would occur as a result of grading to create 3:1 slopes for the building pads. The site plans show that grading would remain outside of, but very close to, the edge of Riparian dripline. Once final grading plans are prepared, they should be evaluated to determine whether impacts may occur within the Riparian boundary, and if so, permitting would be needed from CDFW to cover trimming of riparian trees or work beyond the top of creek bank. The project proposes to remove non-native tree species along the creek corridor, particularly acacia and eucalyptus. A component of the project's Fire Protection Plan approval calls for the removal of this non-native vegetation in the Riparian habitat to reduce fuel loads. The area in which these trees are removed and other locations within the creek setback area would be designated as a mitigation site to receive native tree planting in compensation for the removal of trees throughout other locations of the property, in compliance with the City Municipal Code for Tree Removal 12.24.090 (summarized in Section 1.2). Permitting for the drainage improvements and rip rap structure extending into the creek corridor is also likely to require compensatory mitigation, which is expected to be located along the creek corridor. A Habitat Mitigation and Monitoring Plan (HMMP) shall be prepared by a City-approved qualified botanist or restoration specialist, and submitted to the City and other agencies as a component of the permit applications. Details of the wetland delineation, permitting, and riparian compensatory mitigation effort are required to bring effects on Riparian habitat to a level below significance, and are described below. Riparian habitat onsite as well as downstream of the project could be affected indirectly through stormwater runoff from the construction site. These indirect effects are potentially significant, but can be brought to a level below significance with implementation of measures described below. No other sensitive communities as designated by the CDFW occur onsite. The Annual Grassland community is common in this region, and is not considered sensitive. The Rock Outcrop onsite was not composed of serpentine and did not support rare plants, nor was it of sufficient size to warrant protection as a sensitive biological resource. Impact Bio-4. Construction of a stormwater component of the project would occur in a Riparian and/or creek bank area potentially under federal and state jurisdiction, and considered to be a sensitive resource by the City. This is a significant but mitigable impact. The project is in the early stage of design, and the vesting tentative tract map provided for this analysis shows the rip rap pad and outlet of a stormwater treatment/retention area may extend into the creek zone that is subject to Clean Water Act and California Fish and Game Code requirements. As such, a Preliminary Delineation of Wetlands and Other Waters would need to be prepared to determine the boundaries of USACE, RWQCB and CDFW jurisdiction. If jurisdictional areas would be permanently or temporarily impacted, approval from the above-referenced agencies is required Page 206 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 35 through issuance of a Section 404 permit from the USACE, a Section 401 Water Quality Certification from the RWQCB, and/or a Lake and Streambed Alteration Agreement from the CDFW. Compensatory mitigation would be required as a condition of these permits, as well as under CEQA, at a rati o of at least 1:1. In addition, the City would also require a tree removal permit and compensatory mitigation at a 1:1 ratio for any trees removed outside the riparian habitat that are in the creek setback, and replanting would be needed onsite. The creek setback area that will be enhanced through the removal of non -native vegetation and planting of native tree and grassland species shall be included in the HMMP, and submitted with the permit applications. The mitigation site shall be protected onsite through a deed restriction or another agency approved mechanism. The following mitigation measures are required to lessen project effects to a level below significance under CEQA . Mitigation Measure BIO-4a: Conduct a Preliminary Delineation of Wetlands and Other Waters along the unnamed drainage onsite. A delineation of potential USACE “waters of the United States,” CDFW jurisdictional areas, and RWQCB “waters of the state” shall be conducted in the project's permanent and temporary impact areas to characterize the area’s vegetation, soils and hydrology. The methodology detailed in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0; USACE 2008a) shall be employed. The locations of data points and the jurisdictional boundaries shall be recorded using a Global Positioning System, and mapped on aerial photography. The delineation shall be submitted to USACE, RWQCB and CDFW in support of permit applications. Mitigation Measure BIO-4b: Obtain necessary permits for impacts in jurisdictional areas, implement a compensatory mitigation program, and monitor the success of the program to ensure no net loss of Riparian/Wetland habitat or other waters on the subject property. Once the wetland delineation has been prepared and the design plans finalized, any impacts within jurisdictional areas shall be permitted as follows: 1. During project planning phases, the applicant shall initiate consultation with regulatory agencies prior to submitting applications to obtain a Clean Water Act Section 404 Permit from USACE, a Clean Water Act Section 401 Water Quality Certification from RWQCB, and a California Fish and Game Code Section 1602 Lake and Streambed Alteration Agreement from CDFW. As a component of the application packages, the Preliminary Delineation of Wetlands and Other Waters would be submitted along with permit application packages The applicant would be required to show the City proof of permit acquisition or a determination from each agency that a permit is not required prior to moving forward with storm drainage improvements extending into the creek corridor. Even if permitting is not required by these three agencies, compensatory mitigation would still be required under City policies and CEQA. 2. Once the development footprint within the jurisdictional area has been finalized, the impact area can be determined as needed to complete the permit applications. To compensate for impacts on Riparian habitat and the creek channel, an HMMP will be required by the agencies and City. The HMMP shall address compensatory mitigation for impacts on jurisdictional areas resulting from the construction of stormwater features, and may also include compensatory tree planting for the acacias and other species required by the City for tree removal throughout the property. The HMMP shall detail the location of the mitigation site where Riparian habitat or adjacent upland habitat will be restored or created; techniques to be used; plant species to be used and propagule source; maintenance techniques and schedule; success criteria to meet the goals of the restoration effort; Page 207 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 36 monitoring techniques and schedule for at least five years; and, remedial actions if success criteria are not met. 3. The compensatory tree planting program required by the City shall follow size specifications for each tree removed with a corresponding container size tree to be planted, as detailed in the Municipal Code 12.24.090J. 4. Prior to start of construction activities, the applicant shall retain a qualified biological monitor to ensure compliance with all Clean Water Act and CDFW permit requirements during work adjacent to the creek. The monitor shall be present during the installation of the construction fencing delineating the limits of work in relation to the edge of riparian, creek top of bank and 20-foot creek setback buffer, as described in Mitigation Measure BIO- 2d. Since the Cambria morning-glory compensatory mitigation site is to be located within this buffer, the monitor shall direct appropriate wildlife exclusion and erosion control Best Management Practices (BMPs) to protect Riparian habitat during site preparation for planting. The monitor shall be present during construction of the rip rap pad and any other work within the creek setback area on stormwater structures. The monitor shall also oversee removal of non-native tree species and site preparation for tree planting within the setback. 5. Temporarily disturbed soils within the setback area shall be planted with a native seed mix as described in Table 1 below. 6. The qualified restoration ecologist will work with the applicant to implement the HMMP and conduct annual monitoring and reporting requirements until the final success criteria are attained, which is estimated to occur for a five year period. 7. The mitigation site and buffer area shall be fenced to prevent human activities and ensure the site's permanent protection. Implementation of the above mitigation measures together with those resulting from regulatory agency permitting would reduce construction-related impacts on Riparian habitat to a less than significant level. Impact BIO-5. Stormwater runoff from the project site could potentially result in sediment and/or pollutants entering the creek and affect riparian habitat onsite and/or downstream of the study area. This is a potentially significant but mitigable impact. Construction of the project will involve vegetation removal, grading, and soil excavation. Disturbed soils could erode into the creek and be carried downstream eventually reaching larger waterbodies such as San Luis Obispo Creek if these areas are not stabilized and/or protected prior to significant rainfall. Sedimentation is considered to be a type of pollutant in aquatic systems because it decreases water quality through increased turbidity, fills in pools or causes lateral spread of channels, and covers instream vegetation and other aquatic life. The buildings and infrastructure are planned to be located outside a 20-foot setback from the top of bank or edge of riparian, but will have an increase of impervious surfaces that could result in pollutants from the site being carried into the drainage downstream. The project is designed to have underground and above-ground stormwater retention/treatment basins and other features to manage stormwater once constructed, and the Best Management Practices (BMPs) outlined below are designed to avoid or minimize project effects during and shortly after construction, in the short-term while the basins and other features become established with vegetation. Measures are described for the prevention of erosion, sedimentation, and toxic substances from reaching wetland and riparian habitats adjacent to the site as well as Page 208 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 37 further downstream. Toxic substances include those from construction equipment such as oil, gas, diesel, and hydraulic fluid could leak or be spilled and be carried in stormwater runoff into the creek. To reduce the chance of indirect effects on protected wetland habitats, riparian habitat, and aquatic resources in offsite drainages to a level below significance, the following mitigation measures are required. Mitigation Measure BIO-5: Install appropriate erosion and sediment controls and revegetate graded areas. The following erosion and sedimentation control methods are required to be implemented during and after the construction phases of the project: 1. If possible, the potential for erosion and sedimentation shall be minimized by scheduling construction to occur outside of the rainy season, which is typically defined as October 15 through April 15. Adherence to this measure would also serve as avoidance for the burrowing owl, as described in Mitigation Measure BIO-2a. 2. To minimize site disturbance, all construction related equipment shall be restricted to established roads, construction areas, and other designated staging areas. The creek setback zone shall be clearly marked as described in Mitigation Measure BIO-2d. 3. A Sediment and Erosion Control Plan may be required by the City, and would be prepared by a qualified engineer. The use of silt fence, straw wattles, erosion control blankets, straw bales, sandbags, fiber rolls and other appropriate techniques should be employed to protect the drainage features on and off the property. Biotechnical approaches using native vegetation shall be used as feasible. All areas with soil disturbance shall have appropriate erosion controls and other stormwater protection BMPs installed to prevent erosion potential. All sediment and erosion control measures shall be installed per the engineer’s requirements prior to the initiation of site grading if planned to occur within the rainy season. 4. Spill kits shall be maintained on the site, and a Spill Response Plan shall be in place. 5. No vehicles or equipment shall be refueled within 100 feet of wetland areas, riparian habitat and/or drainage features, and refueling areas shall have a spill containment system installed. No vehicles or construction equipment shall be stored overnight within 100 feet of these areas unless drip pans or ground covers are used. All equipment and vehicles should be checked and maintained on a daily basis to ensure proper operation and to avoid potential leaks or spills. Construction staging areas shall be located in a location where spills would not drain into aquatic habitats. 6. No concrete washout shall be conducted on the site outside of an appropriate containment system. Washing of equipment, tools, etc. should not be allowed in any location where the tainted water could enter onsite drainages. 7. The use of chemicals, fuels, lubricants, or biocides shall be in compliance with all local, state, and federal regulations. All uses of such compounds shall observe label and other restrictions mandated by the U.S. Environmental Protection Agency, California Department of Food and Agriculture, and other state and federal legislation. 8. All project-related spills of hazardous materials within or adjacent to the project site should be cleaned up immediately. 9. All areas with soil disturbance shall have appropriate erosion controls and other stormwater protection BMPs installed to prevent erosion potential. Silt fencing, erosion control blankets, straw bales, sandbags, fiber rolls and/or other types of materials Page 209 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 38 prescribed on the plan shall be implemented to prevent erosion and sedimentation. Biotechnical approaches using native vegetation shall be used as feasible. 10. Areas with disturbed soils shall be restored under the direction of the project engineer in consultation with a qualified restoration ecologist as detailed above. Methods may include recontouring graded areas to blend in with existing natural contours, covering the areas with salvaged topsoil containing native seedbank from the site, and/or applying the native seed mix as described in Table 1. Native seed mix shall be applied to the graded areas in the creek setback area through either direct hand seeding or hydroseeding methods. Seeding with the native erosion control seed mix should be provided on all disturbed soil areas prior to the onset of the rainy season (by October 15). Table 1. Native Erosion Control Seed Mix Species Application Rate (lbs./acre) Bromus carinatus (California brome) 10 Stipa pulchra (purple needlegrass) 5 Trifolium wildenovii (tomcat clover) 5 Vulpia microstachys (six weeks fescue) 5 Total 25 4.1.3 Protected Wetlands There were small areas of wetland vegetation within the area mapped as Riparian in Figure 3, and are outside of project impact areas. Impacts and mitigation within the Riparian area are described above in Section 4.1.2, and no additional effects are expected on the wetland areas, assuming the storm drain outfall is located upslope from the creek channel. Best Management Practices (BMPs) for Riparian habitat described above under Mitigation Measure BIO-5 would also decrease potential indirect effects of construction on wetland habitat to a level below significance. 4.1.4 Interference with Movement of Native Fish or Wildlife, Wildlife Corridors, and Wildlife Nursery Sites The proposed project would not affect the movement of native fish because all work will be conducted outside of stream channel. Site access will be from existing roads on the west, east and south sides of the property and will not require crossing the creek channel. In addition, the reach of the drainage in the subject property is too ephemeral to support fish. No equipment or materials will enter or be placed in the channel that could affect fish downstream. Less than five acres of developed residential and grazed Annual Grassland where the project is located is surrounded on three sides by urban development. Although the northern border of the property is contiguous with undeveloped grassland on CalPoly lands, the subject property is unlikely to be used for wildlife movement because it does not provide linkage to other suitable habitat areas. The site lies at the northern end of the urban area of the City of San Luis Obispo, and as such, there are little opportunities for wildlife should the move through the property as it exists. The creek corridor will be protected with a 20-foot setback that will be enhanced, and this area is expected to be used as a stopover point or corridor for wildlife species that are adapted somewhat to human development. Therefore, there would be no negative impacts of the project on wildlife corridors or movement. Page 210 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 39 The grazed Annual Grassland habitat in the project impact area is not expected to be a wildlife nursery site for any species. Wildlife species that could breed in the area are limited to ground- nesting birds, small mammals such as rodents, and invertebrates. These species would be dispersed throughout the abundant grassland habitat in the general area, and not focused in the study area for reproduction or other key life history stages. The Ornamental trees on the site that would be removed could be used as nesting sites for birds, and these trees will be replaced as described above in Mitigation Measure BIO-4. Until the replacement trees are established, the Riparian corridor will continue to offer opportunities for nesting birds. Ultimately, with the incorporation of the project HMMP, there would be no net loss of nesting habitat on the site. Therefore, there would be no impact of the project on wildlife nursery sites. Because there would be no project impacts on the movement of native fish or wildlife, wildlife corridors or wildlife nursery sites, no mitigation is required. 4.1.5 Conflicts with Local Policies or Ordinances, Such as Tree Preservation The project involves the removal of over 100 planted native and non-native species of trees that are at least 3 inches DBH. As detailed in the City's Municipal Code for Tree Removal 12.24.090, these trees are required to be replaced at a 1:1 ratio for tree planting to be conducted onsite. A tree inventory was conducted as part of this BRA to tag with a unique number, map, identify to species, measure and record the vigor of each of the trees on the property (Figure 4, Appendix D). This information is to be used in support of an application for a tree removal permit from the City. A compensatory tree planting program described above is expected to include areas within the creek setback area, and has been developed to include compensatory mitigation required for impacts in jurisdictional areas and planned non-native species removal in the riparian zone as required by the project's fire plan (Mitigation Measure BIO-4b). It is envisioned that additional tree planting will take place within the residential development to mitigate all tree removal on the site. The applicant would be required to meet the final specifications of the City's municipal code for tree protection and replacement in order to receive permit approval. Once these conditions are met, there would be no additional impacts under CEQA for tree removal. Local policies or ordinances within the General Plan and Municipal Code that apply to this project concerning protection of riparian habitat are described in Section 4.1.2 above. 4.1.6 Conflicts with Conservation Plans No local, regional or state conservation plans have been prepared for the area in which the project is located; therefore, there would be no conflicts with these plans and no mitigation is required. 4.2 Cumulative Effects The proposed project is located on the edge of the urban limits of the City of San Luis Obispo, and is surrounded on three sides by dense residential development. It is currently developed for a single- family residence with a large proportion of landscaping and ornamental plantings. Annual Grassland areas have been grazed in the past by horses and are regularly used by humans. There are no natural habitats within the impact area that have not already been disturbed, and the project would not affect an intermittent creek and its adjacent Riparian habitat. Impacts to Cambria morning glory and associated mitigation requirements were described herein to reduce the impact. A Habitat Mitigation and Monitoring Plan will be developed to enhance the Riparian habitat and its Page 211 of 1225 KMA 468 Westmont Avenue, San Luis Obispo Biological Resources Assessment Alice Jo Meinhold Survivors Trust 40 20-foot setback for impacts to the creek corridor for storm drainage improvements and to support the anticipated Clean Water Act and California Fish and Game Code permitting. Measures are described herein to prevent stormwater runoff from the site from affecting the Riparian habitat on- and off-site during and shortly after construction, and the development plan includes stormwater management techniques for the long-term. With mitigation incorporated as described above, no significant effects on biological resources are expected to occur as a result of project implementation. The loss of less than five acres of a moderately altered site at the edge of existing development would not have any significant effects on biological resources, especially considering that the Riparian habitat will be enhanced and protected. Because there would be no effects of the project in the context of the site's importance in the overall area, the project would not contribute to cumulative effects of other non-federal projects planned in the area. 5.0 CONCLUSIONS The proposed project involves the subdivision of a single-family residential lot into 23 buildable lots. The project impact areas are highly disturbed from many years of human activities and do not contain significant biological resources. Impacts on a rare plant species and Riparian habitat would occur but are proposed to be fully mitigated. This analysis determined that the proposed project meets none of the criteria that trigger mandatory findings of significance under CEQA. With the incorporation of the mitigation measures described herein, project impacts on the six additional impacts to be considered during CEQA review will be reduced to a level below significance. 6.0 REFERENCES Audubon. 2020.

California linderiella Linderiella occidentalis — — — Seasonal pools or vernal pools in grasslands or in sandstone depressions. Can occur in very small pools and are heat tolerant. Not expected. No topographic depressions capable of holding water are present on this sloping site, and species does not occur in flowing water. Recorded from Camp SLO. Monarch butterfly Danaus plexippus pop. 1 — — — (overwinter- ing population) Adults feed on the nectar of various blooming plants. During breeding can be found in fields, pastures, residential areas, grassland and scrub. Eggs are laid on and caterpillars feed on milkweed. Overwinters in wind-protected tree groves of eucalyptus, Monterey pine and cypress along the coast. Present. Individuals were seen flying around the study area during the surveys. Overwintering onsite in the tall eucalyptus and dense riparian is unlikely but potential since overwintering sites have been documented in relatively small groves within urban areas of SLO. Obscure bumble bee Bombus caliginosus — — — Found on ceanothus, coyote brush, thistles, sweet peas, lupines, willows, clover and blackberry. Queens emerge from hibernation in late-January, workers appear in early-March, and males emerge in April. Colonies dissolve in late-October, with only the new queens surviving. Potential. Potential host plants are in the study area. There are historic records from the vicinity, but little is known about this species. San Luis Obispo pyrg Pyrgulopsis taylori — — — Freshwater snail with planktonic larvae. Also has been recorded on rocks and in leaf litter. Potential. Marginal habitat may be present in the onsite drainage, but it is intermittent and appears to dry down on a seasonal basis. Has been recorded nearby in Brizziolari and Chorro creeks, but those drainages have a larger watershed and are more perennial in nature.

Inhabits small clear-water depressions in rock, vernal pools and swales, as well as anthropogenic habitats such as tire ruts, dozer scrapes and railroad pools. Needs standing water for at least 18 days to complete its lifecycle. Not expected. No topographic depressions capable of holding water are present, and species does not occur in flowing water. Known to occur in the south side of San Luis Obispo around the Tank Farm, but no records from along Hwy. 1. Western bumble bee Bombus occidentalis — CE — Generalist foragers and found on agricultural crops such as tomatoes, peppers, cranberries, alfalfa, avocado, apples, cherries, blackberries, and blueberries. Only females survive the winter and establish new colonies the following spring. Colonies contain one queen, female workers, larvae, and when the season nears, male and female reproductive members. Nests are underground in cavities or burrows. Unlikely. Species has undergone substantial range reduction, and no longer occurs in central California. Historic record from 1936 from south of San Luis Obispo. FISH South-central California coast DPS steelhead Oncorhynchus mykiss irideus pop. 9 T — — Adults spawn in freshwater streams with clear, well-oxygenated, cool water and clean gravel substrate. Also require instream cover (branches, logs) and streamside vegetation. Juveniles rear in freshwater reaches or lagoons before going to the ocean to mature, and then return to freshwater to reproduce. Not expected. No suitable habitat is present in the study area. The reach of the unnamed drainage onsite is much too ephemeral to be used by this species. Creek is channelized downstream and traverses highly disturbed urban areas. Documented to occur in Chorro and San Luis Obispo creeks.

Often with loose sandy soils for burial, but also uses small mammal burrows. Preys on native species of ants and other small invertebrates. Not expected. Marginally suitable plant communities are present because biomass is high and open areas are lacking, except in landscaped areas. Very little suitable habitat surrounds the site, and clay soils are unsuitable. Generally absent from urban areas due to non-native ants associated with human presence. No records nearby. California red- legged frog Rana draytonii T — SSC Forages and breeds in streams with deep slow-moving pools, stock ponds, reservoirs, springs, lagoons, and marshes; usually with emergent or riparian vegetation but also found at sites lacking vegetation. Uses riparian and various upland habitats in winter and for dispersal. Unlikely. The onsite drainage does not have sufficient water depth to support any lifestage. Has been recorded historically in Brizziolari Creek, but not observed since 1939. Known to occur throughout the Chorro Creek watershed. Potentially suitable ponds within 1 mile seen on aerial imagery to the NW and on CalPoly, but urban development and Hwy. 1 are likely significant barriers to upland movement. No suitable habitat to the south, so very unlikely to disperse or migrate through the site. Coast Range newt Taricha torosa — — SSC Primarily terrestrial in forests, oak woodlands, chaparral, and rolling grassland. Breeds in ponds, reservoirs and pools of clear streams with rocky substrates and cascades. Not expected. Onsite drainage does not have sufficient amount of water or appropriate rocky habitat with pools and cascades. Has been recorded historically from Brizziolari Creek but not found on CalPoly for several decades.

Northern California legless lizard Anniella pulchra — — SSC Beach dunes, chaparral, pine-oak woodlands, desert scrub, sandy washes, oak woodland, and stream terraces with riparian vegetation. Fossorial species requires moist, loose soils or leaf litter with plant cover or surface objects (rocks, boards, logs, etc.). Can occur in residential areas. Potential. Soils onsite are dense clay and appear to be marginally suitable for the species since this is a highly fossorial species that typically occurs in sandy soils with coastal scrub, chaparral and oak woodland habitats. Riparian habitat is present onsite and includes oak trees with dense leaf litter and the area along the creek corridor could potentially support this species. Legless lizards have been recorded throughout the general area, but few records nearby. Southwestern pond turtle (=western pond turtle) Actinemys pallida (=Emys marmorata) — — SSC Ponds, lakes, rivers, streams, marshes, brackish lagoons, and irrigation ditches with a mosaic of vegetation and open areas for basking. Uses upland areas for nesting and in winter, including woodland, forest, grassland, chaparral, and grasslands. Not expected. No suitable aquatic habitat is present on or near the site. The onsite drainage is too ephemeral and shallow to support this species. The nearest pond seen on aerial photography is well beyond (>4000 feet) the species' distance for upland habitat use. Would not cross Hwy. 1 or urban areas surrounding site. Recorded from Stenner and Chorro creeks on the opposite side of Hwy. 1.

Roosts in buildings, caves, tree hollows, crevices in cliffs or rock outcrops. Feeds on moths. Occurs in California only during the winter, and is rare, found in areas with rugged rocky canyons. Not expected. No suitable rocky habitat is present onsite, and the only record in the vicinity is from 1981. Low probability to occur as a transient during migrations. Monterey dusky-footed woodrat Neotoma macrotis luciana — — SSC Builds large stick middens in chaparral and woodland habitats of moderate canopy and moderate to dense understory. Occurs in the Coast Ranges from Monterey Bay to Los Osos/Atascadero. Reaches its eastern extent at Camp Roberts where it contacts Neotoma fuscipes bullatior and southern extent where Neotoma macrotis macrotis occurs. Unlikely. The subspecies of dusky- footed woodrat in the San Luis Obispo area is reported to be Neotoma macrotis macrotis. No records were in the CNDDB from the vicinity. Several wood rat nests/middens were observed in the creek corridor that could be another species.

Introduction and Background 1.1. Introduction Alice Jo Meinhold Survivors Trust is proposing a new residential development in the City of San Luis Obispo. A drainage study was conducted to be submitted with the Tentative Tract Map application for the proposed project. The intent of that study was to establish the major drainage components that will be included with the proposed project, and to determine their effects on the horizontal and vertical layout of lots, roads, grading, and utilities. This report presents the methods and results generated from that study. 1.2. Project Location and Site Description The proposed project is located in the City of San Luis Obispo in San Luis Obispo County California. The project site is along the north end of Stanford Drive and Cuesta Drive, between both sections of Westmont Ave. The site consists of approximately 4.94 acres of mostly agricultural land, along with some residential area and the wooded area along Twin Ridge Creek. Twin Ridge Creek runs through the western portion of the property and collects drainage from the large agricultural area north of the site as well as runoff from the project site. 1.3. Project Description The project consists of the construction of 23 additional lots expanding the existing residential neighborhood. Most will be along Stanford Drive, while three are on the west side of the creek. In general, the lots are 6,000 sf to 7,000 sf with a few as large as 9,000 sf to 11,000 sf. The project includes extending Stanford Drive and looping it to existing Cuesta Drive. 2. Stormwater Regulations and Design Criteria There are several governing bodies that have regulations and design criteria pertaining to stormwater management for new development. The project is currently located within the City of San Luis Obispo. This project is within the jurisdictions of the following agencies: · City of San Luis Obispo · Central Coast Regional Water Quality Control Board (RWQCB) · California Department of Fish and Wildlife (CDFW) · Federal Emergency Management Agency (FEMA) · US Army Corps of Engineers (USACE) 2.1. City of San Luis Obispo The City of San Luis Obispo has several regulations and standards that pertain to stormwater management, including: · Municipal Code Page 265 of 1225 Drainage Report 3 Westmont Tract · Waterway Management Plan (which includes the Drainage Design Manual) · Standard Specifications and Engineering Standards 2.2. Municipal Code There following sections of the Municipal Code pertain to stormwater management. Creek Setbacks (Municipal Code 17.70.030) The City’s Creek Setback requirement applies to all creeks that are shown on Figure 9 of the Conservation and Open Space Element in the General Plan. Twin Ridge Creek is shown on that figure as a “perennial creek with degraded corridor but able to be restored or repaired.” Per the code, a 20-foot setback is required for Twin Ridge Creek “from the existing top of bank (or the future top of bank resulting from a creek alteration reflected in a plan approved by the city), or from the edge of the predominant pattern of riparian vegetation, whichever is farther from the creek flow line”. Floodplain Management Regulations (Municipal Code 17.84) The City’s Floodplain Management Regulations apply to areas of special flood hazard as identified by FEMA, which are areas that FEMA has identified as subject to inundation by the 1% annual chance flood (100-year flood). The FEMA Flood Insurance Rate Map Number 06079C1066G, Panel 1066 (Appendix A) shows the project site to be outside of FEMA floodplain, so the requirements specific to those areas are not applicable to this project. 2.3. Waterway Management Plan (which includes the Drainage Design Manual) The Waterway Management Plan (WMP) is a watershed-based management plan for San Luis Obispo Creek and its tributaries. The Drainage Design Manual (DDM) is Volume 3 of the WMP and provides design guidance and criteria intended to meet surface water management objectives. The following are some of the sections that pertain to the proposed project: Off-Site Facility Analysis, Design, and Mitigation (DDM 3.3) Runoff shall be managed to prevent any significant increase in downstream peak flows, including 2-year, 10-year, 50-year, and 100-year events. Significant generally means an increase of over 5 percent at and immediately downstream of the project site. Channel and Conduit Capacity (DDM 7.2.1) and Hydraulic Gradient (7.2.10) This section requires that conveyance systems shall be designed to convey the peak runoff for the 10-year design storm with the hydraulic gradient a minimum of 6 inches below the elevation of the inlet grates and manhole covers. In addition, an overland conveyance shall be provided for the 100-year event such that the water surface elevation is at least 1 foot below the finish floor of adjacent structures. Page 266 of 1225 Drainage Report 4 Westmont Tract Inlets and Catch Basins (DDM 7.2.7) Inlets shall be spaced so that gutter flow does not exceed a depth of 6 inches at the face of the curb for a 10-year storm and so that a 100-year storm will not cause any damage and can be contained within the right of way. Outfalls/Open Channel & Pipe Systems (DDM 7.4.5) Outfalls shall be above the mean low water (2-year flow) level unless the City approves an exception. A design exception has been submitted to the City for this project to allow outfalls below the mean low water. 2.4. Standard Specifications & Engineering Standards Provide for Overland Escape (Uniform Design Criteria 5.1.1 B.) All components of drainage systems in public improvements must be evaluated to consider the effect of failure of individual components and identify the route of overland escape. The evaluation must identify any necessary measures to prevent erosion or flooding along this route. Alignment of Drainage Facilities (UDC 5.1.2) Drainage facilities accepting runoff from public streets or other public areas must be in a public street or within a public drainage easement. Drainage easements must be used for drainage purposes exclusively and not combined with easements required for other public utility purposes. Easements for culverts and drainage facilities must be a minimum width of 15-feet. All such easements must provide access and future maintenance working areas. Easements must be along or adjacent to property lines and outside areas of proposed or existing structures. Channel and Swales (UDC 5.1.6) No diversion to roadside ditches will be allowed from natural drainage courses. Channels or swales may be required to be lined to an elevation of at least 1.0-foot above the design hydraulic gradient. The side slopes for channel or swale must not exceed 2:1 or 3:1 in sandy soils. Provide a minimum of 1-foot freeboard at design capacity. Provide typical sections and profile of the existing and proposed channels for a minimum of 500- feet each side of the development to establish an average profile grade through the development. Storm Drains (UDC 5.1.7) Minimum pipe diameter allowable on any storm drain or culverts that are maintained by the City is 18-inches. A lesser size may be approved for privately maintained facilities. Outfalls (UDC 5.1.8) Design energy dissipaters in complicate with the HDM Chapter 870, Channel and Shore Protection Erosion Control. The following items must be shown on the plans: stable rock size (weight), Rock Slope Protection class, dissipater trench dimensions, rock placement method, and RSP fabric type. Culvert energy dissipaters must be designed for the flow Page 267 of 1225 Drainage Report 5 Westmont Tract from the Design Storm. Rock slope protection gradation must conform to Section 72 of the State Standard Specifications. The applicant must provide a Stormwater Control Plan that clearly provides engineering analysis of all Water Quality Treatment, Runoff Retention, and Peak Flow Management controls for projects subject to those performance requirements. 2.5. Central Coast Regional Water Quality Control Board (RWQCB) The RWQCB is responsible for administering and enforcing the National Pollutant Discharge Elimination System (NPDES) permit program, as authorized by the federal Clean Water Act. This program regulates the quality of stormwater that is discharged to surface water bodies. There are two separate permits that this project is required to obtain coverage under, one that applies to stormwater discharges during construction, and one that applies to stormwater discharges after construction is complete. During Construction – Construction General Permit Construction projects that disturb one or more acres of soil during construction are required to obtain coverage under the Construction General Permit. This permit requires the development and implementation of a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP must list Best Management Practices (BMPs) the discharger will use to protect stormwater runoff and the placement of those BMPs. Additionally, the SWPPP must contain a visual monitoring program and a chemical monitoring program for "non-visible" pollutants to be implemented if there is a failure of BMPs. Section A of the Construction General Permit describes the elements that must be contained in a SWPPP. Post-Construction – Phase II Municipal General Permit The Phase II Municipal General Permit applies to stormwater discharges from small Municipal Separate Storm Sewer Systems (MS4s). To comply with the requirements of the Phase II Municipal General Permit, the RWQCB approved Post-Construction Stormwater Management Requirements for Development Projects in the Central Coast Region (Post-Construction Requirements) through adoption of Resolution R3-2013- 0032. A summary of the post-construction requirements is as follows: · Performance Requirement No. 1: Site Design and Runoff Reduction This requirement is intended to limit the disturbance creeks and natural drainage features, minimize compaction of highly permeable soils, limit clearing and grading of native vegetation, minimize impervious surfaces, and minimizing stormwater runoff by collecting it for reuse and by infiltrating it onsite. · Performance Requirement No. 2: Water Quality Treatment This requirement is intended to provide onsite retention or treatment (physical, biological, or chemical) of stormwater runoff from developed areas to reduce the discharge of pollutants from the site. · Performance Requirement No. 3: Runoff Retention The requirement is intended to maintain the pre-developed hydrology with respect to volume, flow rate, and duration for the site by reducing overland flow Page 268 of 1225 Drainage Report 6 Westmont Tract and promoting groundwater recharge. The project site is located in Watershed Management Zone 1 per the map included in Resolution R3-2013-0032, which are areas subject to Performance Requirement No. 3. · Performance Requirement No. 4: Peak Management The requirement is intended to maintain the pre-developed hydrology with respect to peak discharge from the site. This requirement states that the post- development peak flows discharged from the site shall not exceed the pre-project peak flows for the 2-though 10-year storm events. 2.6. California Department of Fish and Wildlife (CDFW) A biological study was conducted to define the limits of jurisdiction for the California Department of Fish and Wildlife (CDFW), which includes portions along Twin Ridge Creek. Proposed work that is within CDFW jurisdiction will be permitted through CDFW. 2.7. Federal Emergency Management Agency (FEMA) The Federal Emergency Management Agency (FEMA) has established flood insurance zones throughout the City of San Luis Obispo. Development within these zones must be in compliance with both the City and FEMA regulations. The current FEMA Flood Insurance Rate Map Number 06079C1066G (revised 11/16/12, Appendix A) for the area, shows the project site to be outside of FEMA floodplain, so the requirements specific to those areas are not applicable to this project. 2.8. US Army Corps of Engineers (USACE) A biological study was conducted to define the limits of jurisdiction for the US Army Corps of Engineers (USACE), which includes Federal Wetlands and Other Waters of the United States as defined by Section 404 of the Clean Water Act. Both types of waterbodies were defined along Twin Ridge Creek. Proposed work that is within USACE jurisdiction will be permitted through USACE. 3. Existing Drainage Conditions 3.1. Description of Existing Offsite Flows that Discharge onto Project Twin Ridge Creek runs along the western portion of the project site and flows south to north. The reach of Twin Ridge Creek that passes through the site begins to form in the agricultural area north of the site by discharge from a residential area and continues south to Highland Dr, where it joins the existing stormwater drainage system. The majority of offsite flow comes from the north and drains to Twin Ridge Creek. The other source of offsite flow is from Westmont Ave and the residential area east of the project site. Page 269 of 1225 Drainage Report 7 Westmont Tract 3.2. Description of Existing Onsite Drainage Conditions The project site consists of approximately 4.94 acres of mostly agricultural land, along with some residential area and the wooded area along Twin Ridge Creek. The area considered for this study is shown on Figure 2. The study area for the existing conditions was divided into six sub-basins, two draining to Twin Ridge Creek, two to Stanford Dr, and two to Cuesta Drive. Sub-basin Exist-TR1 includes the area that drains to the end of the Twin Ridge Creek Line of Investigation. This area is comprised of agricultural and oak woodland and also possibly includes residential runoff from an existing storm drain network. Sub-basin Exist-TR2 is the largest sub-basin in the study and includes a large portion of the agricultural land north of the site, as well as two significant residential areas, the lot and buildings directly north of the site, a portion of Skyline Dr, and the houses to the east of Skyline Drive. Sub-basin Exist-S1 includes the area that drains directly to the Line of Interest (LOI) where Stanford meets the project site. This area includes agricultural, impervious, and residential area. Sub-basin Exist-S2 includes the area just south of the project site draining to a Point of Interest (POI) further along Stanford Drive. This area includes residential and impervious area. Sub-basin Exist-C1 is a small area on the eastern boundary of the project site, draining directly to Cuesta Drive. This area includes residential and impervious area. Sub-basin Exist-C2 includes the area east of the project site including a portion of Westmont and the residential properties north of Westmont. This area includes residential and impervious area. 3.3. Hydrologic Analyses of Existing Conditions Hydrologic Analysis of Study Area Hydrologic analyses were performed as part of this study to estimate the magnitudes of the stormwater runoff from the project study area considering the existing condition of the site. The project study area is shown on Figure 2. The computer program Hydraflow Hydrographs Extension for AutoCAD Civil 3D 2015 was used to perform the hydrologic analyses and is based on the SCS Unit Hydrograph methodology and the following input parameters: · Sub-basin Characteristics o Drainage Area o SCS Curve Number (CN) o Time of Concentration · Precipitation Model: SCS Type 1 24-hour design storm (rainfall depths from Table C-3 SLO WMP, Vol. 1) Page 270 of 1225 Drainage Report 8 Westmont Tract o 2-year rainfall depth: 3.3 inches o 10-year rainfall depth: 4.6 inches o 25-year rainfall depth: 5.7 inches o 50-year rainfall depth: 6.5 inches o 100-year rainfall depth: 6.7 inches · Time Interval: 1 minute Composite curve numbers and times of concentration times were calculated for each sub-basin, and those calculations are included in Appendix B. According to the Web Soil Survey, the site was determined to be soil types C and D. These parameters, along with the sub-basin areas, were input into the hydrologic model for each sub-basin and runoff hydrographs for several design storms were generated. The peak flows for each sub-basin are shown in Table , and the associated hydrographs are included in Appendix B.

Proposed Drainage Conditions 4.1. Description of Proposed Drainage Conditions The project consists of the construction 23 additional lots expanding the existing residential neighborhood. Most will be along Stanford Drive, while three are on the west side of the creek. In general, the lots are 6,000 sf to 7,000 sf with a few as large as 9,000 sf to 11,000 sf. The project also includes widening the existing portion of Stanford Drive, as well as tying the east end into Cuesta Drive. The major proposed drainage features are shown on Figure 4 and include two underground basins, one capturing the majority of runoff from the project site, and the other the offsite runoff from Westmont Ave. Most of the proposed lots will drain to the streets, although lots 1-3 will drain to bioretention areas then directly to the creek. Runoff that collects in the lots will drain to the streets and is proposed to be conveyed by surface flow in the gutters and streets to curb inlets. The inlets will be connected to underground pipes that will convey the runoff to detention facilities. From the detention basins, the flow will be conveyed to either Cuesta or to the creek outfall. There are two emergency overland flow routes proposed, one to Stanford and one to Cuesta, and those are shown on Figure 4. The area considered for this study is shown on Figure 3. The study area for the proposed conditions was divided into seven sub-basins. Sub-basin PROP-TR1 includes the entire onsite area draining directly to Twin Ridge Creek. This area includes wooded land, and future residential and impervious areas. Sub-basin PROP-TR2 includes the the offsite area that drains directly to Twin Ridge Creek. It is identical to EXIST-TR2, but with the subtraction of any onsite area included before. This area includes a large portion of the agricultural land north of the site, as well as two significant residential area, the lot and buildings directly north of the site, a portion of Skyline Dr, and the houses to the east of Skyline Drive. Sub-basin PROP-TR3 includes a majority of the onsite residential and impervious area and drains to the larger detention basin on the site, before draining to Twin Ridge Creek through a proposed storm drain. This area includes residential and impervious area, as well as a small amount of park area. Sub-basin PROP-S1 includes a small portion of the onsite area and drains directly to Stanford Drive. This area includes residential and impervious area. Sub-basin PROP-S2 is identical to EXIST-S2 except that it cuts off at the site boundary. It includes existing residential and impervious area. Sub-basin PROP-C1 is roughly the same as EXIST-C1, but now includes the proposed lots instead of existing residential and impervious area. Page 272 of 1225 Drainage Report 10 Westmont Tract Sub-basin PROP-C2 is the offsite runoff from Westmont, but instead of draining directly to Cuesta Drive, it will be routed into an underground detention basin located between lots 15 and 16. The proposed approach to peak flow management for this project at Twin Ridge Creek involves collecting a portion of the runoff from the proposed development detaining that flow in a detention facility, and then introducing it to Twin Ridge Creek resulting in an overall reduction in peak flow for the system. At Cuesta, the runoff is collected and detained in an underground detention facility and then released onto the proposed site at Cuesta Drive. The proposed drainage at Stanford was designed so that the runoff would match existing drainage conditions. 4.2. Hydrologic Analysis of Proposed Conditions Hydrologic analyses were performed as part of this study to estimate the magnitudes of the stormwater runoff from the project study area considering the proposed condition of the site. The computer program Hydraflow Hydrographs Extension for AutoCAD Civil 3D 2017 was used to perform the hydrologic analyses and is based on the methodology described in Section 3.3. The parameters for all of the detention facilities and outlet structures were input into the model and those parameters are included in Appendix C. Composite curve numbers and times of concentration were calculated for each sub-basin, and those calculations are included in Appendix C. These parameters, along with the sub-basin areas, were input into the hydrologic model for each sub-basin and runoff hydrographs for several design storms were generated. Table 5 shows the peak flows from each sub-basin before any detention. Sub-basin POST-TR3 routes through the detention facility, while sub-basin POST-TR1 and POST-TR2 flow directly to Twin Ridge Creek.

Major Drainage Features Detention Facilities The proposed detention facilities are shown in Figure 4. The Stanford Basin will temporarily store water from PROP-TR3 before introducing it to Twin Ridge Creek. The Cuesta Basin will temporarily story water from the offsite area PROP-C2 before discharging it into Cuesta Dr along with the runoff from PROP-C1. Both facilities are proposed as plastic arch chambers surrounded by gravel to accommodate proposed grading. As part of this study, the basin was sized using a trapezoidal open basin with a flow control structure as shown in Appendix C. Outfalls to Twin Ridge Creek The outfall is proposed in Twin Ridge Creek at the southwest corner of Lot 4 just before the end of the portion of creek being investigated. The proposed outfall consists of pipes that discharge through a headwall onto riprap aprons. 4.4. Post-construction Phase II Municipal General Permit Requirements The post-construction requirements associated with the Phase II Municipal General Permit are summarized in Section 2.5. Compliance with these requirements is intended to be achieved by implementing strategies that include maintaining creek setbacks and constructing retention and detention facilities. A Stormwater Control Plan for Post- construction Requirements was prepared for the project by Cannon under separate cover. Page 274 of 1225 Drainage Report 12 Westmont Tract 4.5. Floodplain Analysis Scope The FEMA Flood Insurance Rate Map Number 06079C1066G shows the project site to be outside of FEMA floodplain, so the requirements specific to those areas are not applicable to this project. Figure DDM 3-2a (Appendix A) from the Drainage Design Manual shows the project site is not within the 100-year floodplain although it appears Twin Ridge Creek was not modeled as part of this figure. As part of this study, we have conducted a 100-yr flood plain analysis of Twin Ridge Creek along the project frontage. Finished floors are set at least 1ft above the 100-yr floodplain line as determined by this study. Methodology A HEC-RAS model was developed based on the flowline and topographic data captured by a field crew in February 2020. HEC-RAS cross sections were identified at locations of apparent channel geometry or slope change. In order to set upstream boundary conditions, a steady state normal depth was assumed with a slope equal to the slope upstream of the model. At the downstream side of the property, the creek continues to flow in the channel which is highly overgrown. Due to the existing vegetation, the field crew was not able to obtain cross sections south of the property line. In order the correctly model this scenario, a Manning’s coefficient for the most downstream section was increased to 0.1, from .045 which was used for the rest of the creek, and the downstream slope for the normal depth calculation was set to 0.5%. The 100 year flow from existing TR-2 as shown in Table 1, Section 3.3 was input into a HEC-RAS model to determine water surface elevations. A mixed flow regime was selected as most appropriate for the 100 year storm event as water elevations varied above and below critical depth. Flood Plain Delineations The boundary of the 100 year floodplain was created in HEC-RAS and exported into AutoCAD. Figure 5 shows the floodplain boundary as determined from the HEC-RAS analysis. The analysis shows that the water does not overtop the banks of the existing stream, and the project decreased the amount of runoff to the creek, thus there is no need to conduct this analysis for a proposed condition.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or Custom Soil Resource Report 8 Page 291 of 1225 landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group (190306) Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 16 Page 299 of 1225 Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required. This product is generated from the USDA-NRCS certified data as of the version date(s) listed below. Soil Survey Area: San Luis Obispo County, California, Coastal Part Survey Area Data: Version 12, Sep 16, 2019 Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Data not available. The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

Neumann 1700 Nipomo Los Osos, CA 93402 Roger Maggio, Fire Marshall San Luis Obispo City Fire Department 2180 Santa Barbara San Luis Obispo, CA February 27, 2020 Regarding: Westmont Subdivision Wildland Fire Protect Report Dear Mr. Maggio, I have been asked to review the above noted project and to make comments on the fire threat and to propose wildfire mitigation measures. I am very familiar with the area, as I was a CAL FIRE firefighter for 29 years, 12 of those years working at the adjacent CAL FIRE headquarters as a Battalion Chief. Fire History Historically, wildland fires in San Luis Obispo County have burned thousands of acres and caused considerable property loss with an occasional life loss. Most of these large fires have occurred in the northern and central portions of the County. Past large fires that have threatened the City of San Luis Obispo include, the Los Pilitas Fire (75,000 acres) and Hwy. 41 Fire (45,000 acres). Every summer wildfires, usually quickly contained, occur in the Camp San Luis area just to the north of the proposed project site. In December of 2001 an approximately 400-acre fire burned on southeast aspect of Bishops Peak, just off O’Connor way. The fuels and topography were similar to the those found at the project site. The fire was quickly contained with no damage to the structures in the area. Fire Factors Three factors contribute to wildland fire spread and threat: • Topography: Canyons, hillsides, ridges and other “lay of the land” features will have a dramatic effect on fire spread. Aspect or orientation of the fuel beds also plays an important role, in general south facing slopes are subject to greater solar radiation, making them drier and thereby intensifying wildland fire behavior. Slope is a critical factor in fire spread, in general fire burns 16 times faster up hill. • Weather: In this coastal region weather plays a key factor in the wildland fire potential. Rain fall occurs primarily between the months of November and April, and ranges between 20 to 25 inches per year. Summers are typically cool with fog and or high humidity the norm. Wind in the area, a key factor in spread, is quite predictable. It typically flows from the north, down the Chorro Valley, and is moisture laden due to the proximity of the ocean, minimizing the fire danger. The fall season will see dryer and warmer days, with occasional east to west wind flows (offshore). This, in combination of the lack of rainfall, will see the fire hazard threat increase. It should be noted that these winds do not have the intensity of the Page 409 of 1225 Southern California “Santa Ana’s” and do not meet typically meet “Red Flag” warning criteria. • Fuel: The arrangement of the fuel on the land is an important consideration. By breaking up or thinning fuel beds one can slow the rapid spread rates of wildfires. In addition, the removal of certain fuels in the horizontal plane can prevent fires from “laddering” into the tops of trees where it may burn hotter and be more difficult to contain. Site Specifics • Topography: The project site is slightly sloped and located near the base of Bishops Peak on the north and northwest aspect. The topography does not negatively impact fire spread or fire protection efforts. In fact, it is favorable as fire, if not driven by wind, will burn upslope away from the site. The slope to the north, behind the project site, increases slightly but not enough to subject the mosaic of fuels to preheating. • Weather: The generally mild coastal climate keeps the wildland fire threat to the site at a minimum. As noted above, the normal wind flow is from the north and it is cool and moisture laden, approaching the site flowing downhill. In the fall moderate east to west offshore wind flows do occasionally occur. The wind direction will then flow around Bishops Peak to the north away from the project site, down the Chorro Valley to the coast at Morro Bay. • Fuels: There are very limited or no fire fuels on the east and south sides of the project, these areas being fully developed residential areas. The area to the west is vegetated in a riparian habit. The remaining north - northeast side is vegetated in light flashy fuels (grass) that has traditionally been grazed by either sheep or cattle. The pine trees surrounding the CAL FIRE station to the northeast are widely spaced and do not present a crowning potential, however, should they be ignited the ember cast would be of concern. The distance to the steeper portions of Bishops Peak where denser brush fields and an oak woodland fuel model is found is considerable; therefore, these fuels do not present a hazard to the project based on distance. . Mitigation Measures The proposed structures in this project are not adequately set back (100 feet) from unmanaged wildland vegetation and riparian areas. The existing City requirements of fire sprinklers, non-combustible roofs, dual window glazing, fire department access, and water supply issues are sufficient. The following additional requirements are necessary: • Rain gutters, when not adequately maintained, will collected leaf material which becomes a receptive fuel bed for embers and sparks and can then transmit fire underneath the non-combustible roof materials. I recommend that rain gutters be protected by non-combustible leaf shields or not allowed. Page 410 of 1225 • Record on all lots a deed restriction that allows for only non-combustible fences and decks are in the subdivision. • Record on all lots a deed restriction that allows for fire resistant landscaping in the back yards of the subdivision. • Require enclosed eves on all structures within the subdivision • Install fireproof vents on all structures (Fire-rated, flame and ember resistant) • Working with the biologist, remove the non-native vegetation in the creek, riparian area, reducing the fuel load. • Install a non-combustible wall (block or steel stud /stucco) wall 36 inches in height all around the northern perimeter of the subdivision. (Installed from the riparian area/ creek on the west side of the project terminating at the property line of the CAL FIRE Station. The purpose of this wall is to interrupt fire progression from the north onto the proposed lots without obstruct the very desirable view of the open space. Conclusion The area fire history and weather patterns, indicate that should a fire occur it will either move slowly onto the proposed subdivision, pushed downhill through the light fuels by the prevailing north wind. Or, move away from the site, up the gentle slope, potential pushed along by an offshore wind flow. In either situation, the construction type and proposed mitigation measures will allow a wildfire fire to pass from or onto the site with little or no damage to the improvements. While the unmanaged wildland fuels located on the north/northeast side of the project do present a threat, the combination of the favorable topography, the strong coastal weather influence, the current fire department standard for fire sprinklers, coupled with the required mitigation measures diminishes this hazard to an acceptable level. _________________________ James A.

The proposed hotel would be approximately 125,200 square feet with a maximum height of 45 feet for occupied buildings and 52 feet for non‐occupied space. The project includes a request for a Planning Commission Use Permit, which is required for a hotel within the BP zone in the Airport Area Specific Plan area. The project includes a request for an exception to standard loading space requirements (one space requested where three spaces is the standard), an exception to an AASP standard to exceed 40% lot frontage side parking to allow for 67% frontage side parking along Broad Street, and exceptions to sign standards to allow for six wall signs (where four is the standard) and placement of wall signs at the third story, where the uppermost point of the second story is the standard height. In July 2007, a hotel project proposed by a previous applicant was approved on the project site (U-5-07, ARC-5-07); however, the project was never constructed, and the entitlements expired. The initial application submittal for the current project proposed two separate hotels with shared surrounding parking areas. The applicant has since revised the project to avoid and provide a 35-foot setback from a wetland feature located in the southwest corner of the site. The applicant has also identified proposed access from Aero Drive, which would cross an adjacent parcel located between the project site and Aero Drive, and has provided a separate pedestrian site entry that would connect to the existing sidewalk on Aero Drive.1 Additional non-vehicular access (i.e., pedestrian, bicycle) is provided directly to Broad Street. 1 In the past, Aero Drive was located along the project’s southern boundary and has since been realigned by the County, creating a gap between this project site and Aero Drive.

The ARC moved to recommend that the Planning Commission find the project consistent with the AASP Design Guidelines and Community Design Guidelines, and approve the project with the following considerations: Consider pedestrian access to the site, especially from the northern corner of the site near the Broad Street sidewalk, and access to SLO Brew/The Rock to the north. Consider replacing the sine wave corrugated metal with metal that is similar to the other metal siding on the building, and perhaps a different color (6-0-1) (Attachment C, ARC Staff Report and Meeting Minutes). Page 416 of 1225 ARCH-0165-2020, USE-0294-2019, & EID-0650-2020 Planning Commission Report – July 28, 2021 Page 5 The applicant is proposing to remove five trees onsite that are subject to tree removal permitting, including: four Brazilian pepper (Schinus terebinthefolius) trees, (1) six inches, (1) eight inches, and (2) ten inches in diameter; and one golden wattle/acacia (Acacia longifolia), six inches in diameter (Attachment B, Sheet L1.0, Conceptual Landscape Plan). The Conceptual Landscape Plan includes 93 trees to be planted on site, including the following identified below in Table 3, Proposed Compensatory Planting Plan. Table 3: Proposed Compensatory Planting Plan Tree Type and Quantity Tree Species Street trees along Broad Street (11) London plane tree (Platanus acerifolia) Pin oak (Quercus palustris) Accent trees (11) Golden medallion (Cassia leptophylla) Western redbud (Cercis occidentalis) Chitalpa (multi-trunk) (Chitalpa tashkentensis) Crape myrtle (Lagerstroemia indica ‘Tuscarora’) Canopy shade trees (16) Bronze loquat (Eriobotrya deflexa) Southern magnolia (Magnolia grandiflora ‘Majestic Beauty’) Drake evergreen elm (Ulmus parvifolia ‘Drake’) Parking lot trees (31) Strawberry tree (Arbutus unedo) Western redbud (Cercis occidentalis) Crape myrtle (Lagerstroemia indica ‘Nachez’) Narrow trees near building (18) Chinese fringe flower (Chionanthus retusus) Little gem magnolia (Magnolia grandiflora ‘Little Gem’) Perimeter trees (17) ‘Marina’ arbutus (Arbutus ‘Marina’) Coast live oak (Quercus agrifolia) Pin oak (Quercus palustris) The Tree Committee will consider this request on July 26, 2021 and will provide a recommendation to the Planning Commission. Following the Tree Committee hearing, staff will provide a memorandum to the Planning Commission, which will also be available to the public, that summarizes the Tree Committee’s recommendation. 4.0 PROJECT ANALYSIS The proposed project must conform to the standards and limitations of the Zoning Regulations and Engineering Standards and be consistent with the applicable standards identified in the AASP, and Community Design Guidelines. Staff has evaluated the project’s consistency with relevant requirements and has found the project to be consistent, as discussed in this analysis. Page 417 of 1225 ARCH-0165-2020, USE-0294-2019, & EID-0650-2020 Planning Commission Report – July 28, 2021 Page 6 3.1 Consistency with the General Plan The General Plan Land Use Element (LUE) provides limited policies for the Business Park land use designation other than the intent is to provide for research and development and light manufacturing in a campus setting and should provide high quality design of public and private facilities. Business Park land use designations are typically found within Specific Plans, which offer additional guidance on policy objectives, as described in greater detail below. 3.2 Consistency with the Airport Area Specific Plan The project site is located on Aero Drive, adjacent to the San Luis Obispo County Regional Airport. AASP Chapter 4.0 (Land Use, Special Areas) notes that l and uses in the airport vicinity must be regulated in order to minimize the potential for conflicts between these uses and airport operations. The primary instrument for maintaining compatibility and safety is the Airport Land Use Plan (ALUP) prepared and maintained by the San Luis Obispo County Airport Land Use Commission (ALUC). AASP land uses have been planned with thorough consideration given to the ALUP. Specifically, urban uses are not proposed in areas where incompatible levels of noise can be expected, or where there is an unacceptable risk that an accident could occur. The AASP, which was found to be consistent by the ALUC prior to its adoption, requires approval of a Planning Commission Use Permit in order to allow hotel development in the Business Park zone and land use designation. In July 2007, a hotel project proposed by a previous applican t was approved on the project site (U-5-07, ARC-5-07); however, the project was never constructed, and the entitlements expired. AASP Section 4.2.1 (Business Park) states that “areas designated Business Park are primarily for research and development, light manufacturing, and business services that are compatible with each other and with airport operations. Activities that are supportive of, or accessory to, the primary activities may be allowed as well.” The proposed dual - brand hotel is consistent with the AASP and BP zone because it would support the airport by providing proximate lodging, parking, and amenities for guests using the airport as a method of travel, in addition to other visitors to San Luis Obispo. Airport and Transportation Noise AASP Table 4-3 (Allowed Uses) notes that hotel uses in the BP zone are identified in the ALUP as noise sensitive and specific sound-attenuation requirements may apply. The current ALUP identifies a 45 decibel (dB) threshold for interior noise levels for hotels, which is the same as the City’s Noise Element threshold (45 dB, interior noise). Based on the recent updated ALUP, the project site is located outside of the 60 CNEL2 contour line for airport-related noise. As documented in the noise analysis prepared for the project (Attachment D, see attached documents), which considered both airport and roadway noise, existing daytime sound levels within the project site range from 60 to 66 dB. Based 2 CNEL = Community Noise Equivalent Level: The noise metric adopted by the State of California for land use planning and describing airport noise impacts. This noise metric compensates for the increase in people's sensitivity to noise during evening and nighttime hours. Community Noise Equivalent Levels are typically depicted on maps by a set of contours, each of which represents a series of points having the same CNEL value (ALUP 2021). Page 418 of 1225 ARCH-0165-2020, USE-0294-2019, & EID-0650-2020 Planning Commission Report – July 28, 2021 Page 7 on the site plan, parking areas along the Broad Street frontage would be located within the 60 to 66 dB contour. As noted in the noise analysis, mandatory requirements for acoustical control required by the State Green Building Standards Code3 require that projects located within the 65 CNEL noise contour of an airport or roadway incorporate Sound Transmission Class (STC) 50 for walls and STC 40 for windows, which would reduce interior noise below 45 dB, consistent with the AASP, ALUP, and City Noise Element. Furthermore, at the most conservative level, a typical structure covered with siding will have a STC rating of 39 dBA based on current methods. Basic dual-pane vinyl windows will achieve an STC rating of 28 dBA. Averaged out, this results in a combined STC rating of approximately 33 dBA, meaning a typical exterior wall assembly will reduce 33 dB of sound transfer, resulting in an interior noise level less than 45 dB. The noise analysis also noted that outdoor use areas that face noise sources may experience noise exceeding 60 dB; the applicant has addressed this issue by orienting the hotel building such that the outdoor pool area and patio are internal to the site, and noise generated by transportation sources along Broad Street would be attenuated by the building itself below 60 dB. Therefore, based on the orientation of the building and site amenities, and compliance with exiting Building and Green Code regulations, the project would be consistent with the AASP, ALUP, and City Noise Element. AASP Development Standards As shown in Table 2 above (Project Statistics), the project is consistent with AASP Development Standards (AASP Section 4.4). The proposed project would not exceed the height permitted by the AASP (52 feet). Based on the County of San Luis Obispo’s recent adoption of the updated Airport Land Use Plan (ALUP) on May 26, 2021, which included revisions to the ALUP’s safety zones, the project site is located within Zone 6, Traffic Pattern Zone4, which allows for a maximum density of 300 persons per acre. Applying the current ALUP, the maximum allowed density for the site is 1,512 persons; the project would result in a density of 627 persons, less than and consistent with ALUP standards. AASP Community Design Standards The ARC considered AASP Community Design Standards upon their review of the project and did not identify any inconsistencies. As noted above, the ARC provided two considerations to improve pedestrian access to proximate businesses north of the project site, and replacement of one material type on the building. Staff recommends that the Planning Commission support these considerations, which are addressed in proposed conditions of approval #3 and #5. Lot Frontage Side Parking. AASP standard 5.4.1 states that: “parking lots shall be located at the rear or side of buildings, rather than between the front facade of the building and the street. Side parking shall not exceed 40 percent of the frontage of the lot on the primary street.” 3 Title 24, Chapter 6, Article 1 of the California Administrative Code; California Green Building Code (CCR, Title 24, Part 11, Chapter 5) 4 The County ALUP Update can be viewed online: https://www.slocounty.ca.gov/Departments/Planning- Building/Community-Engagement/Active-Planning-Projects/Airport-Land-Use-Plan-Update.aspx Page 419 of 1225 ARCH-0165-2020, USE-0294-2019, & EID-0650-2020 Planning Commission Report – July 28, 2021 Page 8 The applicant is requesting an exception to an Airport Area Specific Plan Standard 5.4.1 to allow for 67% lot frontage side parking along Broad Street where 40% is the standard for the primary street. The project site is a corner lot, and a majority of the parking spaces are proposed along the northern property boundary and internal to the site. Approximately 270, non-continuous linear feet of parking spaces are provided along the east property boundary, facing Broad Street, with a 10-foot-deep landscape buffer between the parking spaces and the sidewalk. The project’s primary access would be from Aero Drive. Staff Analysis. As noted above, the project was revised since the original application submittal to avoid and provide a minimum 35-foot setback from a wetland feature in the southwest corner of the project site. The project also complies with Code requirements for fire truck access surrounding the structure. The orientation of the building provides an entrance facing Broad Street; however, the primary face of the building is angular and generally faces Aero Drive, the access road to the airport. Due to the prior realignment of Aero Drive, a majority of the project site does not directly front Aero Drive. Therefore, the proposed site plan generally meets the intent of the parking lot standard. Based on the environmental constraints of the site, the applicant’s desire to meet standard parking requirements, compliance with Code requirements for fire safety and emergency access, the proposed 10-foot landscape buffer and tree plantings along Broad Street that will provide some screening of the parking area, the project’s primary access from Aero Drive, and ARC’s recommendation of consistency with the AASP including the requested exception, staff recommends the Planning Commission consider and grant the requested exception for 67% lot frontage side parking along Broad Street based on finding 5 identified in the Draft Resolution. 3.3 Requested Zoning Regulations Exception Loading Space Exception/Waiver Section 17.72.100 (Onsite Loading Standards) states that every new building 10,000 square feet or more occupied by certain uses, including a hotel, shall provide off-street loading and unloading areas. Based on the size of the project, three spaces would be required. Section 17.72.100.B. allows for a waiver of the loading space requirement provided that “the applicant has satisfactorily demonstrated that, due to the nature of the proposed use, such loading space will not be needed.” The project includes a request for an exception to standard loading space requirements (one space requested where three spaces is the standard). Staff Analysis. The proposed project consists of a dual-branded hotel, with shared lobby, kitchen, laundry, and office areas. Based on the operation of the hotel, which only includes amenities for guests, it is reasonable that no more than one loading space is necessary, and staff recommends the Planning Commission consider and grant the requested exception, based on finding 6 identified in the Draft Resolution. 3.4 Requested Sign Regulations Exception Page 420 of 1225 ARCH-0165-2020, USE-0294-2019, & EID-0650-2020 Planning Commission Report – July 28, 2021 Page 9 Quantity and Placement of Wall Signs Exception The proposed project includes requested exceptions to sign standards to allow for six wall signs (where four is the standard) and placement of wall signs at the third story, where the uppermost point of the second story is the standard height. The applicant’s reason for the request is based on the orientation of the building along Broad Street, and to provide for visibility from both travel lanes of Broad Street and Aero Drive, and identification of the primary entrance as seen from the parking area. Staff Analysis. The ARC considered and recommended approval of the requested exception, based on the orientation of the building relative to Broad Street and Aero Drive. Staff recommends the Planning Commission consider and grant the requested exception, based on findings 7 and 8 identified in the Draft Resolution, as the placement of signage would not create clutter and would improve visual identification of the connected hotels and primary entrance to the shared lobby. 5.0 ENVIRONMENTAL REVIEW An Initial Study (IS) was prepared in accordance with the California Environmental Quality Act (CEQA) in order to conduct a project-specific analysis, and a Mitigated Negative Declaration (MND) is recommended for adoption (Attachment D). The IS/MND identifies that the project would potentially affect the following environmental factors unless mitigated: air quality, biological resources, cultural resources, ge ology and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, land use and planning, transportation, tribal cultural resources, and utilities and service systems. Mitigation measures have been identified to reduce these potential impacts to less than significant. A 30-day public review period extended from April 22, 2021 through May 24, 2021. Comments were received from the California Department of Fish and Wildlife, Department of Toxic Substances Control (DTSC), San Luis Obispo Council of Governments (SLOCOG), and the Air Pollution Control District (APCD). All comments have been addressed in the revised IS/MND and are summarized in Attachment D for reference. The modifications to the IS/MND do not require recirculation of the document because the amendments constitute minor modifications and clarifications to an adequate MND and do not include significant new information that would result in a new significant environmental impact or a substantial increase in the severity of a significant environmental impact. All new text is indicated by underlined, bold, and italicized text. Deleted text is indicated by strike-through. 6.0 OTHER DEPARTMENT COMMENTS The project has been reviewed by various City departments and divisions including Planning, Engineering, Transportation, Building, Utilities, City Attorney, and Fire. Staff has not identified any unusual site conditions or circumstances that would require special conditions. Other comments have been incorporated into the draft resolution as conditions of approval.

PC-XXXX-21 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF SAN LUIS OBISPO, CALIFORNIA, APPROVING THE AIRPORT HOTEL PROJECT INCLUDING APPROVAL OF A PLANNING COMMISSION USE PERMIT TO ALLOW A HOTEL IN THE BUSINESS PARK ZONE, AND ASSOCIATED EXCEPTIONS TO LOT FRONTAGE SIDE PARKING STANDARD, LOADING SPACE STANDARD, AND SIGN REGULATIONS FOR WALL SIGNS AS REPRESENTED IN THE STAFF REPORT DATED JULY 28, 2021, AND ADOPTION OF THE ASSOCIATED INITIAL STUDY/MITIGATED NEGATIVE DECLARATION (ARCH-0165-2020, USE-0294-2019, and EID-0650-2020; 950 AND 990 AERO DRIVE) WHEREAS, the Architectural Review Commission of the City of San Luis Obispo conducted a meeting via teleconference on May 3, 2021, recommending the Planning Commission approve the design of the project based on consistency with the Community Design Guidelines and Airport Area Specific Plan (AASP), pursuant to a proceeding instituted under ARCH-0165- 2020, Sunsmit, LLC, applicant; and WHEREAS, the Tree Committee of the City of San Luis Obispo conducted a meeting on July 26, 2021 at the City’s Corporation Yard, 25 Prado Road, San Luis Obispo, California, recommending the Planning Commission find the project consistent with the Tree Regulations pursuant to a proceeding instituted under ARCH-0165-2020, Sunsmit, LLC, applicant; and WHEREAS, the Planning Commission of the City of San Luis Obispo conducted a meeting on July 28, 2021 at City Hall, 990 Palm Street, San Luis O bispo, California, pursuant to a proceeding instituted under ARCH-0165-2020, USE-0294-2019, and EID-0650-2020, Sunsmit, LLC, applicant; and WHEREAS, notices of said public hearing were made at the time and in the manner required by law; and WHEREAS, the Planning Commission has duly considered all evidence, including the testimony of the applicant, interested parties, and the evaluation and recommendations by staff, presented at said hearing. NOW, THEREFORE, BE IT RESOLVED by the Planning Commission of the City of San Luis Obispo to approve the proposed project, consisting of entitlements ARCH-0165-2020, USE-0294-2019, and EID-0650-2020. This resolution is based on the following findings: SECTION 1. Findings. The Planning Commission hereby grants approval of the Airport Hotel project and associated exceptions (ARCH-0165-2020, USE-0294-2019, and EID-0650- 2020) based on the following findings: 1. As conditioned, the project will not be detrimental to the health, safety, and welfare of persons living or working at the site or in the vicinity because the project respects site constraints and Page 423 of 1225 Resolution No. _____ (2021 Series) Page 2 will be compatible with the scale and character of surrounding neighborhoods , which primarily consist of business park, commercial, and airport-related uses. 2. The project conforms to the General Plan, Airport Area Specific Plan (AASP), Airport Land Use Plan (ALUP), and meets Zoning Regulations requirements for the Business Park Zone. 3. As conditioned, the project is consistent with Airport Area Specific Plan land use policies and the intended development pattern of the Business Park (BP) zone because the hotel will support the adjacent San Luis Obispo Regional Airport by providing lodging and parking for airport users in addition to other travelers to San Luis Obispo. 4. As conditioned, the project design is consistent with the City’s Community Design Guidelines and Chapter 5 (Community Design) of the AASP through its placement of buildings, parking, landscaping, and pedestrian access that are compatible with the design and scale of neighboring structures, and by providing articulation, varied roof heights, and architecturally articulated entry features facing Broad Street and Aero Drive. Lot Frontage Side Parking 5. Granting an exception to strict compliance with lot frontage side parking limitations is consistent with the intent of Airport Area Specific Plan standards because the project site is a corner lot with primary access taken from Aero Drive, and the primary face of the building is angular and generally faces Aero Drive, the access road to the airport. Due to the prior realignment of Aero Drive, a majority of the project site does not directly front Aero Drive and is separated by a vacant parcel. In addition, the project demonstrates compliance with parking requirements, Code requirements for fire and emergency access to the building, and the proposed 10-foot landscape buffer and tree plantings along Broad Street will provide some screening of the parking area. Loading Space Exception/Waiver Finding 6. The proposed project consists of a dual-branded hotel, with shared lobby, kitchen, laundry, and office areas; therefore, only one loading space is necessary to serve operation of the dual- brand hotel. Sign Regulations Exceptions 7. There are unusual circumstances applying to the property which make strict adherence to the Sign Regulations impractical or infeasible, including the location of the corner lot roughly at the intersection of Broad Street and Aero Drive, the building’s primary entrance on Aero Drive and secondary pedestrian/non-vehicular access on Broad Street, and visibility of signage as seen from Broad Street and Aero Drive. 8. As conditioned, the exceptions granting six wall signs, where four signs is the standard in the Business Park (B-P) zone and allowing for the placement of the wall signs at the third floor of the dual-branded hotel is consistent with the intent and purpose of the Sign Page 424 of 1225 Resolution No. _____ (2021 Series) Page 3 Regulations and the exceptions are not being granted where alternative options of allowed signage could provide an adequate alternative for sufficient visibility to the public with equal or superior design. Based on the orientation of the building, the proposed signage would be visible from both travel lanes of Broad Street and Aero Drive to allow for sufficient business identification and would not result in visual clutter onsite or in comparison with the surroundings. SECTION 2. Environmental Review. An Initial Study/Mitigated Negative Declaration (IS/MND) has been prepared in accordance with the California Environmental Quality Act (CEQA) to evaluate the potential environmental effects of the proposed project. The Planning Commission adopts the IS/MND and Mitigation, Monitoring, and Reporting Program, based on incorporation of the following findings and mitigation measures, which will reduce potential environmental impacts to less than significant. CEQA Findings 1. An Initial Study (IS) was prepared in accordance with the California Environmental Quality Act (CEQA) in order to conduct a project-specific analysis, and a Mitigated Negative Declaration (MND) is recommended for adoption (Attachment D). The IS/MND identifies that the project would potentially affect the following environmental factors unless mitigated: air quality, biological resources, cultural resources, geology and soils, greenhouse gas emissions, hazards and hazardous materials, hydrology and water quality, land use and planning, transportation, tribal cultural resources, and utilities and service systems. Mitigation measures have been identified to reduce these potential impacts to less than significant. 2. A 30-day public review period extended from April 22, 2021 through May 24, 2021. Comments were received from the California Department of Fish and Wildlife, Department of Toxic Substances Control (DTSC), San Luis Obispo Council of Governments (SLOCOG), and the Air Pollution Control District (APCD). All comments have been addressed in the revised IS/MND. The modifications to the IS/MND do not require recirculation of the document because the amendments constitute minor modifications and clarifications to an adequate MND and do not include significant new information that would result in a new significant environmental impact or a substantial increase in the severity of a significant environmental impact.

AQ-5 Asbestos Material in Demolition. Demolition activities can have potential negative air quality impacts, including issues surrounding proper handling, demolition, and disposal of asbestos-containing material (ACM). ACMs could be encountered during demolition or remodeling of existing buildings. Asbestos can also be found in utility pipes/pipelines (transite pipes or insulation on pipes). If utility pipelines are scheduled for removal or relocation or a building(s) is proposed to be removed or renovated, various regulatory requirements may apply, including the requirements stipulated in the National Emission Standard for Hazardous Air Pollutants (40 Code of Federal Regulations [CFR] 61, Subpart M - asbestos NESHAP). These requirements include but are not limited to: (1) notification to the APCD; (2) an asbestos survey conducted by a Certified Asbestos Inspector; and (3) applicable removal and disposal requirements of identified ACM. More information on asbestos can be found at http://www.slocleanair.org/business/asbestos.php. Monitoring Program: Measures AQ-1 through AQ-5 shall be incorporated into project grading and building plans for review and approval by the City Community Development Department. Compliance shall be verified by the City during regular inspections, in coordination with the SLOAPCD, as necessary. The applicant shall submit the geologic evaluation detailed in measure AQ-3 to the City Community Development Department upon completion. BIOLOGICAL RESOURCES BIO-1 The following measures shall be implemented prior to and during construction to avoid potential direct mortality and loss of California red-legged frogs: 1. Prior to the initial site investigation and subsequent ground-disturbing activities, a qualified biologist will instruct all project personnel in worker awareness training, including recognition of California red-legged frogs and their habitat. 2. A qualified biologist will conduct preconstruction surveys within the project area no earlier than 2 days before ground-disturbing activities. 3. No activities shall occur after October 15 or the onset of the rainy season, whichever occurs first, until May 1, except for during periods greater than 72 hours without precipitation. Activities can only resume after site inspection by a qualified biologist. The rainy season is defined as a frontal system that results in depositing 0.25 inches or more of precipitation in one event. 4. Vehicles to and from the project site will be confined to existing roadways to minimize disturbance of habitat. 5. Prior to movement of a backhoe in the project area, a qualified biologist will make sure the route is clear of California red-legged frogs. 6. If a California red-legged frog is encountered during excavations, or any project activities, activities will cease until the frog is removed and relocated by a U.S. Fish and Wildlife Service-approved biologist. Any incidental take will be reported to the USFWS immediately by telephone at (916) 414-6600. Page 428 of 1225 Resolution No. _____ (2021 Series) Page 7 BIO-2 The following measures shall be implemented prior to and during construction to avoid impacts to hydrological resources located within and in the vicinity of the project site: 1. The limits of all work areas shall be clearly delineated in the field during construction and personnel shall be informed of the need to avoid impacts to jurisdictional aquatic features (i.e., waters and wetlands). 2. For short-term, temporary stabilization, an erosion and sedimentation control plan shall be developed outlining Best Management Practices (BMPs) and implemented to prevent erosion and sedimentation into the channel during construction. Acceptable stabilization methods include the use of weed-free, natural fiber (i.e., non-monofilament) fiber rolls, jute or coir netting, and/or other industry standards. BMPs shall be installed and maintained for the duration of the construction period. 3. The mapped limits of jurisdictional areas shall be clearly shown on all site plans and flagged prior to the start of any construction activity within 50 feet of the limits of the drainage. 4. All equipment and materials shall be stored a minimum of 35 feet from the edge of the drainage at the end of each working day, and secondary containment shall be used to prevent leaks and spills of potential contaminants from entering the drainage. 5. During construction, washing of concrete, paint, or equipment and refueling and maintenance of equipment shall occur only in designated areas a minimum of 35 feet from all drainages and aquatic features. Sandbags and/or sorbent pads shall be available to prevent any fluid releases from entering the drainage. 6. Construction equipment shall be inspected by the operator on a daily basis to ensure that equipment is in good working order and no fuel or lubricant leaks are present. 7. Where feasible, the project shall incorporate low impact development (LID) features, including bioswales and permeable pavers, into the overall site design to retain runoff on site and avoid increased surface runoff into the drainage. 8. Where feasible, the project shall incorporate vegetated buffers, bioswales, and/or rain gardens on the drainage side of the development. 9. The use of landscaping plants that are known or have potential to become invasive shall be prohibited. BIO-3 If any ground disturbance will occur during the nesting bird season (February 1–September 15), prior to any ground-disturbing activity, a preconstruction nesting bird survey shall be conducted by a qualified biologist within 1 week prior to the start of activities. If nesting birds are located on or near the project site, they shall be avoided until they have successfully fledged, or the nest is no longer deemed active. A non-disturbance buffer of 50 feet will be implemented for non-listed, passerine species and a 250-foot buffer will be implemented for raptor species. No construction activities will be permitted within established nesting bird buffers until a qualified biologist has determined that the young have fledged or that proposed construction activities would not cause adverse impacts to the nest, adults, eggs, or young. If special-status avian species are identified, no work shall be conducted until an appropriate buffer is determined in consultation with the City and the California Department of Fish and Wildlife and/or U.S. Fish and Wildlife Service. Page 429 of 1225 Resolution No. _____ (2021 Series) Page 8 Monitoring Program: The survey requirements of Mitigation Measures BIO-1 and BIO-3 shall be incorporated into the project grading and building plans for review and approval by the City Community Development Department and verified through submittal of a preconstruction nesting bird survey report to the City Community Development Department. The City Community Development Department shall confirm that all BMPs included in BIO-2 to avoid impacts to aquatic resources are incorporated into the grading plans prior to approval. Compliance shall be verified by the City prior to the start of construction and during regular inspections, as necessary. CULTURAL RESOURCES CR-1 Prior to construction activities, a City-qualified archaeologist shall conduct cultural resource awareness training for all construction personnel including the following: 1. Review the types of archaeological artifacts that may be uncovered; 2. Provide examples of common archaeological artifacts to examine; 3. Review what makes an archaeological resource significant to archaeologists and local Native Americans; 4. Describe procedures for notifying involved or interested parties in case of a new discovery; 5. Describe reporting requirements and responsibilities of construction personnel; 6. Review procedures that shall be used to record, evaluate, and mitigate new discoveries; and 7. Describe procedures that would be followed in the case of discovery of disturbed as well as intact human burials and burial-associated artifacts. CR-2 If cultural resources are encountered during subsurface earthwork activities, all ground - disturbing activities within a 25-foot radius of the find shall cease and the City shall be notified immediately. Work shall not continue until a City-qualified archaeologist assesses the find and determines the need for further study. If the find includes Native American- affiliated materials, a local Native American tribal representative will be contacted to work in conjunction with the City-approved archaeologist to determine the need for further study. A standard inadvertent discovery clause shall be included in every grading and construction contract to inform contractors of this requirement. Any previously unidentified resources found during construction shall be recorded on appropriate California Department of Parks and Recreation (DPR) forms and evaluated for significance in terms of California Environmental Quality Act (CEQA) criteria by a qualified archaeologist. If the resource is determined significant under CEQA, the qualified archaeologist shall prepare and implement a research design and archaeological data recovery plan, in conjunction with locally affiliated Native American representative(s) as necessary, that will capture those categories of data for which the site is significant. The archaeologist shall also perform appropriate technical analysis, prepare a comprehensive report, and file it with the Central Coast Information Center (CCIC), located at the University of California, Santa Barbara, and provide for the permanent curation of the recovered materials. CR-3 In the event that human remains are exposed during earth disturbing activities associated with the project, an immediate halt work order shall be issued, and the City Community Page 430 of 1225 Resolution No. _____ (2021 Series) Page 9 Development Director and locally affiliated Native American representative(s) (as necessary) shall be notified.

The San Luis Obispo County Regional Airport borders the property to the south and west. The property is zoned Business Park, within the Airport Area Specific Plan, and within the Airport Land Use Planning Area zones 4 and 5. The property is vacant but Airport Management leased a portion of the site for parking during construction of the new terminal. Project Description The proposed project consists of developing a three-story dual branded hotel with on- site parking. The hotel will have 204 guest rooms and guest amenities that include outdoor patio/dining areas, meeting space, fitness room, breakfast area and bar. These amenities will be for hotel guest only; they will not be open to the public. The hotel is anticipated to be a trademark hotel although at this time a trademark has not been selected. The project is setback from the state jurisdictional wetlands a minimum of 35 feet to avoid impacts to the wetland area. Project Architecture Contemporary materials, architectural reliefs, and distinguishing color combinations create a high-tech hotel with a warm, inviting impression. The architectural style of the hotel combines the “airport architecture” with hotel architecture harmoniously. Metal awnings, metal trellises and low planter walls create appealing dining and meeting places. An artistic palette of trees, bushes and groundcovers varying in textures, colors, form and height enhance the development and add a lushness to the patio and outdoor areas Page 468 of 1225 The entry point for the project site is located off of Aero Drive creating easy access to the hotel. The hotel has a porte cochere allowing easy traffic flow within the parking area for guest registration and parking.

Due to the nature of the hotel business, loading spaces are not critical. An exception to reduce the required 3 loading spaces to 1 spaces is being requested. The signage proposed on the hotel is placed above the architectural reliefs at the entry and in strategic locations. Placing the signage at these locations will require the signage to exceed the 25 foot height limit. The signage is attached to the building, not free standing. An exception to the height limit is being requested for this project. Inclusionary Housing Requirement The inclusionary housing requirement will be fulfilled through the alternative in-lieu payment. Public Art Proposal The developers will include public art in the project valued at one-half of one percent (.5%) of the cost of construction over $100,000 or contribute an amount equal to the value of the required art to the City’s art-in-lieu account or donate a comparably valued piece of art to the City. The estimate public art fee will be $115,00 Architectural Review Committee This project was presented to the Architectural Review Committee (ARC) on March 18, 2019. ARC supported the phased project, the site design of the project with a few suggestions and the request for the exception to the signage height limit. Since the ARC meeting. The project has been redesigned to avoid all impacts to the adjacent wetland area. Please refer to report prepared by Terr-Verde. Page 471 of 1225 San Luis Obispo Airport Hotels Airport Specific Plan Requirements Prepared for: Sunsmit, LLC Prepared by: Planning Solutions Pamela Jardini J.D. planningsolutions@charter.net 805-801-0453 Revised March 10, 2020 Page 472 of 1225 Airport Specific Plan Requirements Project Description This project consists of developing a three-story hotel on with on-site parking. The hotel is anticipated to be a trademark hotel although at this time a trademark has not been selected. Please refer to the hotel project statement for a detailed project description. Airport Specific Plan Requirements The following standards are applicable per the Airport Specific Plan. The project’s conformity to the design standards follows each standard in italics. 4.2.1 Business Park Areas designated Business Park are primarily for research and development, light manufacturing, and business services that are compatible with each other and with airport operations. Activities that are supportive of, or accessory to, the primary activities may be allowed as well. The hotel is a good fit for the Business Park zone since it is a complimentary and supportive use to the airport. Its location is convenient for tourists and business visitors. The hotel is located off of Broad Street which provides access to future transit routes and direct access to downtown. The hotel will provide shuttle service to San Luis Obispo’s downtown. The San Luis Obispo Regional Airport partnered with SLO Transit to provide airport customers and employees access to the airport via public transit. The Architectural Review Committee found this use to be appropriate for the site. 5.1.1 Principal buildings shall be oriented parallel to the street. The project is located at the corner of Broad and Aero Street. The hotel is oriented parallel to Broad Street - the public domain. Orienting the hotel parallel to Broad Street is compatible with the neighborhood, positively influences the aesthetic character of the street scape and enhances the entrance to the airport. 5.1.2 No more than one double-loaded parking bay will be allowed between the street and the front of the building. The project proposes one double-loaded parking bay between the hotel and Broad Street. Fire and emergency services require access to all sides of the building and the front parking lot is necessary to accomplish this safety feature. The hotel’s architectural reliefs and landscaping enhance the presence of the hotel and diminish the parking area. Page 473 of 1225 5.1.3 Direct pedestrian access shall be provided from the street serving the project to the main entrance. Direct pedestrian access is provided from Broad Street to the entrance via a path delineated by pavers, framed by landscaping and accented by a metal canopy at the entrance to the hotel. Pedestrian access from Aero Drive is delineated by pavers from the public sidewalk to the hotels’ entries and exterior patio areas. 5.1.4 Buildings shall have architecturally articulated entry features facing the street. The hotel provides an entry and lobby area that face Broad Street. The building is articulated with various materials, colors, off-set façade relief and a prominent covered entrance. Entrance to the hotel is from Aero Drive. The front of the hotel has a porte-cochere facing Aero Street with direct access to the hotel’s lobby. 5.4.1 Parking lots shall be located at the rear or side of buildings, rather than between the front facade of the building and the street. Side parking shall not exceed 40% of the frontage of the lot on the primary street. The parking areas are screened with landscaping and setback from Broad Street and Aero Road. Parking is wrapped around the building and avoids encroaching into the wetland’s jurisdictional limits. Standard 5.1.2 allows one double-loaded parking bay between the front of the building and the street. Fire and emergency services require access to all sides of the building and the front parking lot is necessary to accomplish this safety feature. 5.4.2 Where parking layout exceeds two rows in depth (i.e., one double-loaded parking bay), parking lot aisles shall be oriented perpendicular to the building(s) (i.e., aligned in direction of pedestrian movement) to increase pedestrian safety. The parking area in front of the hotel (facing Aero Street) is oriented perpendicular to the buildings. The parking areas are landscaped and a pedestrian path is delineated with pavers to provide safe pedestrian travel between parking spaces and the hotels. 5.4.4 Parking lots shall be planted with shade trees in a pattern and number that can be reasonably expected to shade at least 50% of the lot surface within ten (10) years of planting, and provide a nearly continuous canopy at maturity The landscaping plan for the parking area show cases a variety of trees, shrubs groundcovers in various textures and seasonal colors. At maturity the landscaping will meet or exceed the 50% shade requirement. Page 474 of 1225 5.4.5 A 10% reduction in the required number of parking spaces may be granted by the Director for development within one-quarter mile of a regularly scheduled transit stop. The San Luis Obispo Regional Airport partnered with SLO Transit to provide airport customers and employees access to the airport via public transit. The project qualifies for a 10% reduction in the required number of parking spaces. The project as proposed does not incorporate the 10% reduction allowance. 5.6.1 Loading docks and refuse collection areas are not permitted in the area between the building and the street. No loading docks are proposed. The trash receptacles are not visible from the street, are enclosed, and located to the side and rear property lines. 5.6.2 Each commercial or industrial loading or outdoor recycling or waste collection area shall be located on the side of a building opposite from parcel lines or street frontages of any land designated for residential use. The property does not border a residential use. 5.6.3 Storage, service, trash and recycling collection areas shall be located either within an enclosure or behind a visual barrier. All storage, service, trash, and recycling collection areas are within a stucco enclosure with metal doors. The enclosures will incorporate the materials and colors of the buildings. 5.6.4 Loading dock areas shall be set back, recessed, and screened from view by walls, berms, or plantings. No loading docks are proposed. 5.6.5 Exterior on-site utilities (including drainage systems, sewers, gas lines, water lines, electrical, telephone, and communications wires and equipment) shall be installed underground except, where required to be above ground by government agencies The project is in compliance with this standard. 5.6.6 Rooftop mechanical equipment shall be screened by parts of the roof, or architecturally compatible screening features, so the equipment is not visible from the ground outside the site or open space areas to the public. On sites designated Business Park, such screening shall make rooftop equipment not visible from a viewpoint outside the site and at the same height as the equipment. The mechanical equipment is screened from view by parapets at the edge of the roof. Page 475 of 1225 5.10.1 Building facades visible from streets shall vary in modules of 20 meters (66 feet) or less. On any building facade, continuous wall planes longer than 30 meters (100 feet) should be avoided. Where interior functions require longer continuous spaces, exterior walls should have architectural features such as columns or pilasters at least every 20 meters. Such architectural features shall have a depth of at least 3 percent of the length of the facade, and shall extend at least 20 percent of the length of the facade. The project is consistent with this standard 5.10.2 Facades that face public streets shall use elements such as arcades, awnings, entry features, windows, or other such animating features along at least 60 percent of their horizontal length. The façades facing both Broad Street and Aero Drive have metal awnings, canopies over their entry, and metal vine trellises. The various finishes include painted stucco in four complimentary colors, metal siding, and fiber cement siding. This combination of materials spans 100% of the horizontal length and visually reduces the overall building mass, creates interesting shadows and provides visual interest while maintaining a pedestrian scale. A.11.1 Table 4.9 shows building height standards for the planning area. This Business Park Land Use category height limit for occupied space is 45 feet. The height limit for non-occupied space is 52 feet. The project is in compliance with both these height limits. Goal 5.17.1: Development in the Airport Area is subject to the requirements of the City’s Public Art ordinance. The developers will include public art in the project valued at one-half of one percent (.5%) of the cost of construction over $100,000 or contribute an amount equal to the value of the required art to the City’s art-in-lieu account or donate a comparably valued piece of art to the City. The estimated public art fee is $115,000 Goal 5.18.1: Building identity signs shall be limited to major site entries from public roadways. Corporate and business identity signs can be placed on the buildings themselves, as long as they are located near the building entrance and are for identification within the site (i.e., not from public roadways). Hotel Signage is located on the facade of the building above the entries facing Broad Street, the interior entry and on the building side fronting Aero Drive. One monument sign is located at the entry to the site from Aero Drive. We are requesting an exception to the sign height limit so that the signs are placed in a logical and visually noticeable place on the buildings. The Architectural Review Committee supported this exception request. Page 476 of 1225 Goal 5.18.2: Signs on poles or other raised structures are not allowed in the planning area. This project is consistent with this goal. Goal 5.18.3: All signs shall be located on private property. The signs are located on the buildings or on the monument sign; all signs are on private property. Goal 5.18.4: Entry signs shall be externally illuminated. The light source shall be fully shielded from view from roadways and pedestrian walkways. Lighting levels shall be as low as possible while providing adequate illumination for signs to be seen by motorists. All signs are eternally illuminated and the light source is shielded from view.

One double‐loaded parking bay is proposed between the building and Broad Street. The primary entrance and porte cochere are located internally to the site facing towards Aero Drive, with a pedestrian walkway extending from Aero Drive to the main entrance. A pedestrian side entry is provided on the elevation facing Broad Street, which leads into the lobby on the ground floor. This side entry is accentuated by use of colors and materials (white‐colored stucco extending from the ground to the roofline), an aluminum‐ framed storefront and metal canopy, and the pedestrian access from Broad Street would be delineated with pavers and framed by landscaping. The ARC should discuss if additional articulation is warranted to further accentuate either entrance. Standard 5.4.1: Parking lot location at rear or side of buildings; side parking shall not exceed 40 percent of the lot frontage A majority of the parking is proposed along the northern property boundary and internal to the site. Approximately 270, non‐ continuous linear feet of parking spaces are provided along the east property boundary, facing Broad Street, with a 10‐foot deep landscape buffer between the parking spaces and the sidewalk. The ARC should discuss if an exception to allow for parking spaces along approximately 67% of the Broad Street frontage is appropriate, given the environmental constraints of the site and Code requirements for fire truck access surrounding the structure. Page 483 of 1225 ARCH 0165‐2020, USE 0294‐2019 950 & 990 Aero Drive Page 4 Goal 5.9: Architectural character Guideline A: Building forms should generally be simple and expressive of their function and construction technology Guideline D: Building design should be varied and distinctive, and in harmony with its context The architectural character, building forms, and design of the dual‐ brand hotel are generally simple, and incorporate varied materials, vertical and horizontal off‐sets, and accents including colors, canopies, low walls, trellis features, and accentuated windows. The ARC should discuss the project’s overall consistency with this goal and guidelines. Goal 5.10: Scale and massing Standard 5.10.1: Building facades visible from streets shall vary in modules of 66 feet or less; continuous wall planes longer than 100 feet should be avoided; where interior functions require longer continuous spaces, exterior walls should have architectural features such as columns or pilasters at least every 66 feet. Such architectural features shall have a depth of at least 3 percent of the length of the facade, and shall extend at least 20 percent of the length of the façade. Standard 5.10.2: Facades facing public streets shall use animating features along at least 60 percent of the horizontal length. The façades facing both Broad Street and Aero Drive vary in modules of 66 feet or less, and provide various finishes including painted stucco in four complimentary colors, metal siding, and fiber cement siding. This combination of materials spans the horizontal length, and are intended to visually reduce the overall building mass, create shadows, and provide visual interest. Horizontal trim bands, colored fiber cement panels between windows, vertical fins at the window frames, and inset and pushed out wall planes provide variation in the massing of the structure. Animating features include metal awnings, canopies over entries, and metal vine trellises. The ARC should discuss if any modifications to scale and massing should be provided to further consistency with these standards. Goal 5.12: Architectural façade and treatment Guidelines A‐F: articulation, detailing, human scale, visual interest and distinctiveness, defined entries, and design quality. Please see above regarding architectural features and treatment. The ARC should discuss if any modifications to architectural detailing should be provided to further consistency with this standard. Page 484 of 1225 ARCH 0165‐2020, USE 0294‐2019 950 & 990 Aero Drive Page 5 7.0 ARC CONCEPTUAL REVIEW COMMENTS A previous version of this project was conceptually reviewed by the ARC on March 18, 2019 (Attachment 2, ARC Minutes and previous conceptual plans).1 Since that time, the project has been modified to avoid a wetland feature present within the site, and to also provide a minimum 35‐foot setback from the feature. As a result, the previous concept that showed two separate hotel buildings has been modified to the current proposal, which consists of a connected dual brand hotel, with a shared parking area and lobby. The ARC’s comments are identified below; the ARC should discuss these items while considering the overall changes to the project subsequent to conceptual review. Comment Discussion Items As a hotel and gateway into San Luis Obispo, the Commission would like to see more personality to the structures, including more articulation, variation, and window detail; use less corrugated metal; and, possibly use warmer materials and colors. The façades facing both Broad Street and Aero Drive vary in modules of 66 feet or less, and provide various finishes including painted stucco in four complimentary warmer colors, metal siding, and fiber cement siding. Horizontal trim bands, colored fiber cement panels between windows, and inset and pushed out wall planes provide variation in the massing of the structure. Animating features include metal awnings, canopies over their entry, and metal vine trellises. In addition to the renderings, Sheets A8.0 and A8.1 provide focused drawings of the porte cochere, metal trellis features, and window details. The proposed materials include the use of corrugated metal; the ARC should discuss if the balance of materials and colors is appropriate and generally consistent with the AASP Guidelines and Standards above. Commission recommends maintaining pedestrian appeal per Goal 5.1 of the Airport Area Specific Plan; consider entrance facing Broad Street. The project’s main entrance and porte cohere face Aero Drive, and a covered side entrance and pedestrian walkway are provided facing Broad Street. Refer to discussion item above (Standard 5.1.1 through 5.1.4). Commission is concerned about the roof line on Hotel 2. Commission recommends hotel could have more articulation in the roof line without adding to the overall height as more elements are added to the elevation. “Hotel 2” was previously located in the western portion of the site; the current site plan presents a connected dual‐brand hotel with flat roofs, and some variation in building height, with non‐occupied architectural features extending up to 52 feet in height. Adjust circulation of vehicles and pedestrians around entrances. The entire site plan has been revised as noted above, with only one main entrance and porte cochere to serve both hotels. 1 ARC Agenda Report, March 18, 2019 available here Page 485 of 1225 ARCH 0165‐2020, USE 0294‐2019 950 & 990 Aero Drive Page 6 Comment Discussion Items Consider softening patio walls by material type and additional landscaping. The entire site plan has been revised as noted above, with the patio and pool area located adjacent to the hotel in the western portion of the area to be developed. A variation in solid wall and metal bar fencing is proposed, with landscaping to be located between the walkway and the fence/wall to soften its appearance. Consider location of trash enclosure, including noise generated during trash pick‐up. The site plan currently shows one, screened trash enclosure located in the northeast corner of the property. The location of the trash enclosure was approved by San Luis Garbage. Commission recommends incorporating an accent color into Hotel 1; also consider providing a bigger surface for the green screens. The revised project incorporates wall mounted trellis and climbing vine elements on all elevations of the structure. Accent colors are provided on all facades. Commission recommends activating the entrance and porte cochere. The porte cochere and main entrance are accentuated by decorative pavers and low‐level landscaping, accent trees, and use of color (white‐colored stucco extending from the ground to the roofline). 8.0 ACTION ALTERNATIVES 8.1 Recommend the Planning Commission approve the project based on consistency with the Design Guidelines, which may include specific conditions of approval or recommendations to be considered by the Planning Commission. 8.2 Continue the project to a hearing date uncertain. An action continuing review of the project should include specific direction to the applicant and staff on pertinent issues. 8.3 Recommend denial the project. An action denying the application should include findings that cite the basis for denial and should reference inconsistency with the General Plan, Airport Area Specific Plan, Zoning Regulations or other policy documents. 9.0 ATTACHMENTS 9.1 Project Plans 9.2 Conceptual review ARC Minutes and conceptual plans Page 486 of 1225 ATTACHMENT 1Page 487 of 1225 ATTACHMENT 1Page 488 of 1225 ATTACHMENT 1Page 489 of 1225 ATTACHMENT 1Page 490 of 1225 ATTACHMENT 1Page 491 of 1225 ATTACHMENT 1Page 492 of 1225 ATTACHMENT 1Page 493 of 1225 ATTACHMENT 1Page 494 of 1225 ATTACHMENT 1Page 495 of 1225 ATTACHMENT 1Page 496 of 1225 ATTACHMENT 1Page 497 of 1225 ATTACHMENT 1Page 498 of 1225 ATTACHMENT 1Page 499 of 1225 ATTACHMENT 1Page 500 of 1225 ATTACHMENT 1Page 501 of 1225 ATTACHMENT 1Page 502 of 1225 ATTACHMENT 1Page 503 of 1225 ATTACHMENT 1Page 504 of 1225 ATTACHMENT 1Page 505 of 1225 WM WMWMWMSDSDWM > > > WM SDSDSD???1111123334B R O A D S T R E E T ( H I G H W A Y 2 2 7 )RIGHTOF WAYN35° 15' 10"W399.20'A E R O D R I V E PROPERTYLINEPROPERTYLINERIGHTOF WAYN38° 19' 24"W412.62'N52° 00' 20"E236.75'N52° 00' 20"E315.41'N47° 10' 11"W410.03'N50° 30' 32"E231.01'N50° 30' 32"E299.87'HOTEL176.50 FF10.0'SLOPE ESMT48 PM 35DRAINAGE &ACCESS ESMT48 PM 35DRIVEWAY ESMTDOC.

DTSC recommends that additional investigation be conducted prior to any development to evaluate if releases occurred and contamination exists within the project area and surrounding areas. The Initial Study acknowledges the potential for historic, current, and future activities on and near the project site to release hazardous substances on the project site. Mitigation Measures AQ-3 and AQ-4 have been identified to require the applicant to complete a geologic evaluation and follow all applicable protocol and procedures if naturally occurring asbestos or other hazardous materials are determined to be present on-site. The applicant is also required to comply with SLOAPCD regulations related to materials containing asbestos (Mitigation Measure AQ-5). Based on required compliance with state and local regulations regarding construction activities and a search of the Cortese list, no other potentially significant impacts from release of hazardous substances were identified ( refer to Section 9, Hazards and Hazardous Materials, Impact Discussion d). San Luis Obispo County Air Pollution Control District (SLOAPCD) – May 24, 2021 The APCD supports the project proponents on their use of infill development, as it is consistent with SLOCOG's Regional Transportation Plan and Sustainable Communities Strategy. No revisions to the Initial Study are required in response to this comment. Portable Equipment, 50 horsepower (hp) or greater, used during construction activities may require a California statewide portable equipment registration (issued by the California Air Resources Board) or an APCD permit. The project would be required to obtain all necessary permits from the SLOAPCD prior to construction. No revisions to the Initial Study are required in response to this comment. The APCD recommends updating Question b in Section 3, Air Quality, to reflect the analysis used in the Emissions Modeling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (Attachment 2 of the project's Initial Study) as this report used CalEEMod to calculate construction emissions. Impact Discussion b in Section 3, Air Quality, in the Initial Study has been revised to reflect the analysis used in the Emissions Modeling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (Attachment 2 of the Initial Study). Page 533 of 1225 Based on the analysis in Attachment 2, construction impacts would be below APCD thresholds with the assumption that Tier 3 off-road construction equipment would be used. Because of this assumption, the APCD recommends including a mitigation measure that states all off-road construction equipment shall be tier 3 or higher to be consistent with Attachment 2 modeling assumptions and ensure emissions are below APCD thresholds. Mitigation Measure AQ-2 in Section 3, Air Quality, in the Initial Study has been revised to include an additional measure that requires all off-road construction equipment to be Tier 3 or higher. On page 26 of the Initial Study, operational impacts for this project were evaluated using "SLOAPCD's operational screening criteria for air quality analyses" and the "project would not exceed the identified operational thresholds established by the SLOAPCD." According to Table 1-1 in the APCD's 2012 CEQA Handbook, this project would exceed the ROG+NOx 25lbs/day operational threshold as this project would exceed 177 rooms. Based on Table 1-1, this project would require mitigation. However, further analysis used in the Emissions Modeling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (Attachment 2) conclude the project would below APCD operational thresholds. The APCD recommends updating this section to reflect the analysis used in Attachment 2 as this report used CalEEMod to calculate operational emissions which is a more refined analysis than Table 1-1. Impact Discussion b in Section 3, Air Quality, in the Initial Study has been revised to reflect the analysis used in the Emissions Modeling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (Attachment 2 of the Initial Study). The Emissions Modeling Report for the San Luis Obispo Airport Hotels Project quantified the GHG emissions for the project in 2023 and 2030 and compared the GHG impacts to the service population threshold in the City of San Luis Obispo's qualified Climate Action Plan. Mitigation measure GHG-1 provides a mechanism for the project to address lifetime GHG impacts in excess of the service population threshold. The APCD recognizes a service population threshold may not be the most applicable threshold choice for projects like hotels that have relatively low numbers of employees relative to project GHG emissions. After GHG reductions are quantified from on-site and other potential mitigation measures, the APCD recommends quantifying annual impacts over the life of the project to also account for reduction in project impacts due to future emission reduction technology that is included in CalEEMod, the emission modelling tool used by AMBIENT Air Quality & Noise Consulting. Mitigation Measure GHG-1 in Section 8, Greenhouse Gas Emissions, in the Initial Study has been revised to require annual impacts to be quantified over the life of the project to also account for reduction in project impacts due to future emission reduction technology that is included in the CalEEMod. Page 534 of 1225 The guidance in the APCD's Interim CEQA GHG document should be used to compare the project to existing applicable plans, policies, or regulations that have been legally adopted for the purpose of reducing GHG emissions. In addition to comparing the project to the City of San Luis Obispo's Climate Action Plan, the APCD recommends comparing the project to the: San Luis Obispo Council of Governments Regional Transportation Plan/Sustainable Community Strategies (RTP/SCS): Project proponents should work with SLOCOG early in the project development process to foster consistency with the land use and transportation policies, goals, action strategies, and preferred growth scenario identified in the current RTP/SCS; and Demonstrate project consistency with the 2017 Scoping Plan; all applicable components within the 2017 Scoping Plan should be evaluated for consistency. One such component is transportation: In the GHG section of the project's CEQA evaluation, a project can demonstrate it is consistent with the transportation GHG reduction assumptions in the 2017 Scoping Plan if it can show 15% VMT reduction. Projects which cannot achieve 15% VMT reduction need to demonstrate how they will achieve equivalent GHG reductions by implementing design changes or other offsetting GHG mitigation to comply with the 2017 Scoping Plan. Note: SB 743 recommends a project achieve 15% VMT reduction and is evaluated in the transportation section of a project's CEQA evaluation. The difference between SB 743 and the 2017 Scoping Plan is SB 743 recommendation can only be met by VMT reductions, whereas the 20174 Scoping Plan consistency can be achieved with VMT reductions, whereas the 2017 Scoping Plan consistency can be achieved with VMT reductions and design changes or Impact Discussion b in Section 8, Greenhouse Gas Emissions, in the Initial Study has been revised to include additional discussion of the project's consistency with the RTP/SCS and 2017 Scoping Plan and incorporates additional VMT discussion and reference to Mitigation Measures TR-1 and TR-2.

California Department of Fish and Wildlife (CDFW) – May 24, 2021 The Project site contains habitat suitable to support special-status plant species meeting the definition of rare or endangered under CEQA Guidelines Section 15380 including, but not limited to, CRPR 1B.1 Hoover’s button-celery (Eryngium aristulatum var. hooveri), and the State designated rare and CRPR 1B.1 Adobe sanicle (Sanicula maritima). Although there was a preliminary field study done on October 3rd, 2019 that did not find any rare plants, that study was outside of the blooming period where the plants could have been identified. To evaluate potential impacts to special-status plant species associated with the Project, CDFW recommends conducting the following evaluation of the Project area, editing the MND to include the following additional measures, and including the following mitigation measures as conditions of approval. Recommended Mitigation Measure 1: Special- Status Plant Surveys If suitable habitat is present, CDFW recommends that the Project site be surveyed for special-status plants by a qualified botanist following the “Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities” (CDFW 2018). This protocol, which is intended to maximize detectability, includes the identification of reference populations to facilitate the likelihood of field investigations occurring during the appropriate floristic period. In the absence of protocol-level surveys being performed, additional surveys may be necessary. Recommended Mitigation Measure 2: Special- Status Plant Avoidance CDFW recommends that special-status plant species be avoided whenever possible by delineating and observing a no-disturbance buffer of at least 50 feet from the outer edge of the plant population(s) or specific habitat type(s) required by special-status plant species. If buffers cannot be maintained, then consultation with CDFW is warranted to determine appropriate minimization As discussed in Impact Discussion a, b in Section 4, Biological Resources, in the Initial Study, low-suitability habitat is present within the drainage and associated wetland habitat on-site for Congdon’s tarplant, Hoover’s button-celery, and adobe sanicle. If present, Congdon’s tarplant would have been detectable at the time of surveys completed for the project site; therefore, the species is not expected to occur on-site. Though considered unlikely due to degraded site conditions, Hoover’s button-celery and adobe sanicle may be present within the ephemeral drainage and associated wetland habitat located in the southwestern portion of the project site. The project would avoid impacts to the ephemeral drainage and associated wetland habitat present within the project site through project design and the identified setback of 35 feet from State jurisdictional features; therefore, all habitat suitable for special- status plants within the project site would be avoided. Implementation of Mitigation Measure BIO-2 would further ensure direct and indirect impacts to hydrological resources and habitat suitable for special- status plant species are avoided by requiring mapping and delineation of work areas and implementation of Best Management Practices (BMPs). Page 536 of 1225 and mitigation measures for impacts to special- status plant species. Recommended Mitigation Measure 3: State- listed Plant Take Authorization If a plant species listed pursuant to CESA or State designated as rare is identified during botanical surveys, consultation with CDFW is warranted to determine if the Project can avoid take. If take cannot be avoided, take authorization prior to any ground-disturbing activities may be warranted. Take authorization would occur through issuance of an ITP by CDFW, pursuant to Fish and Game Code section 2081 subdivision (b) for State listed threatened or endangered plants or pursuant to the Native Plant Protection Act and Fish and Game Code section 1900 et seq. for State designated rare plants. The Project contains activities that may result in the Project site being subject to CDFW’s regulatory authority pursuant Fish and Game Code section 1600 et seq. Fish and Game Code section 1602 requires an entity to notify CDFW prior to commencing any activity that may (a) substantially divert or obstruct the natural flow of any river, stream, or lake; (b) substantially change or use any material from the bed, bank, or channel of any river, stream, or lake; or (c) deposit debris, waste or other materials that could pass into any river, stream, or lake. “Any river, stream, or lake” includes those that are ephemeral or intermittent, such as the unnamed stream within the Project site, as well as those that are perennial in nature. For additional information on notification requirements, please contact our staff in the Lake and Streambed Alteration Program at (559) 243-4593. It is important to note, CDFW is required to comply with CEQA, as a Responsible Agency, when issuing a Lake or Streambed Alteration Agreement (LSAA). If inadequate, or no environmental review, has occurred, for the Project activities that are subject to notification under Fish and Game Code section 1602, CDFW will not be able to issue the Final LSAA until CEQA analysis for the project is complete. This may lead to considerable Project delays. As discussed in Impact Discussion a, b in Section 4, Biological Resources, in the Initial Study, the project would avoid impacts to the ephemeral drainage and associated wetland habitat present within the project site through project design and the identified setback of 35 feet from State jurisdictional features; therefore, no impacts to the ephemeral drainage within the project site would occur. Implementation of Mitigation Measure BIO-2 would further ensure direct and indirect impacts to hydrological resources are avoided by requiring mapping and delineation of work areas and implementation of Best Management Practices (BMPs). CEQA requires that information developed in environmental impact reports and negative declarations be incorporated into a data base which may be used to make subsequent or supplemental No revisions to the Initial Study are required in response to this comment. Page 537 of 1225 environmental determinations. (Pub. Resources Code, § 21003, subd. (e).) Accordingly, please report any special-status species and natural communities detected during Project surveys to the California Natural Diversity Database (CNDDB). The Project, as proposed, would have an impact on fish and/or wildlife, and assessment of filing fees is necessary. No revisions to the Initial Study are required in response to this comment. San Luis Obispo Council of Governments (SLOCOG) – May 24, 2021 SLOCOG encourages the City and County to coordinate with regard to the in-progress ICE Step 2 Analysis for the SR 227 intersection at Farmhouse Lane and incorporate the final build alternative into City planning documents. The intersection operational improvement should incorporate safe pedestrian and bicycle crossings that allow access from the bi- directional Class I shared use path on the west side of SR 227 to the northbound Class IV bike lanes on the east side of SR 227. SLOCOG recommends that impacts from this project to the SR 227 corridor are considered. An appropriate payment toward the City’s TIF to construct the operational improvement at Buckley Road/SR 227 and the segment of the Edna- Price Canyon Trail between Buckley Road and Farmhouse Lane should also be considered. As discussed in Impact Discussion a in Section 17, Transportation, in the Initial Study, the project would require the payment of the City’s standard Traffic Impact Fees. No revisions to the Initial Study are required in response to this comment.

The Lead Agency is receiving this notice from DTSC because of the Project’s proximity to the San Luis Obispo County Airport (Airport). Use of 218 acres of the Airport by the U.S. Army Air Corps and the California National Guard was initiated in November 1938. On January 4, 1943, the Navy leased 208 acres of the Airport from the County of San Luis Obispo. The use of the Airport property by the Army Air Corps and the National Guard continued until at least November 1941. In May 1946, the Navy abandoned the airport facilities, leaving all improvements to the County of San Luis Obispo. Disposal records were neither complete nor specific. The site has not yet been investigated for environmental concerns. Use of the Airport by the County of San Luis Obispo has continued to the present. (https://www.envirostor.dtsc.ca.gov/public/profile_report?global_id=80000759). Undiscovered contaminants of concern, resulting from military or other aeronautical operations, may remain in the Airport’s subsurface. DTSC recommends that additional investigation be conducted prior to any development to evaluate if releases occurred and contamination exists within the Project area and surrounding areas. Should you need any assistance with an environmental investigation, please submit a request for Lead Agency Oversight Application, which can be found at: https://dtsc.ca.gov/wp-content/uploads/sites/31/2018/09/VCP_App-1460.doc.

We have completed our review of the proposed project located at 950 & 990 Aero Drive in San Luis Obispo. The proposed project includes a 125,000-square foot, 204-room three-story hotel on a 5.04-acre site. The property is currently zoned Business Park, within the Airport Area Specific Plan, and within the Airport Land Use Planning Area zones 4 and 5. Project construction would require 4.33 acres of site disturbance and approximately 10,000 cubic yards (cy) of cut and 8,900 cy of fill. The area is less than 1,000 feet from sensitive receptors and is within a naturally occurring asbestos area. The following comments are formatted into 3 sections. The (1) General Comment Section states information pertinent to the applicant, lead agency, and/or public. The (2) Air Quality and (3) Greenhouse Gas Emissions Sections may state mitigation measures and/or rules and requirements in which the APCD recommends be set as conditions of approval for the project. The applicant or agent should contact the APCD Engineering & Compliance Division about permitting requirements stated in the (1) General Comment Section. The lead agency may contact the APCD Planning Division for questions and comments related to proposed conditions of approval in the (2) Air Quality and (3) Greenhouse Gas Emission Sections. Both Divisions can be reached at (805) 781-5912. Please Note: The APCD recently updated the Land Use and CEQA Webpage on the slocleanair.org website. The information on the webpage displays the most up-to-date guidance from the SLO County APCD, including the 2021 Interim CEQA Greenhouse Gas Guidance, Quick Guide for Construction Mitigation Measures and Quick Guide for Operational Mitigation Measures. Page 541 of 1225 APCD Comments Regarding the SLO Airport Hotel Project May 24, 2021 Page 2 of 4 (1) General Comments Infill within Urban Reserve Lines & Village Reserve Lines The APCD encourages balance of residential and commercial infill within the existing urban reserve lines (URLs) and village reserve lines (VRLs), as this is consistent with the land use goals and policies of the APCD’s Clean Air Plan. Increasing density can reduce emissions and vehicle miles traveled (VMT) by minimizing the number of trips and travel distances and encourage active transportation. The APCD supports the project proponents on their use of infill development, as it is consistent with SLOCOG’s Regional Transportation Plan and Sustainable Communities Strategy. Construction Permit Requirements Based on the information provided, we are unsure of the types of equipment that may be present during the project’s construction phase. Portable equipment, 50 horsepower (hp) or greater, used during construction activities may require a California statewide portable equipment registration (issued by the California Air Resources Board) or an APCD permit. The following list is provided as a guide to equipment and operations that may have permitting requirements but should not be viewed as exclusive: • Portable generators and equipment with engines that are 50 hp or greater; • Electrical generation plants or the use of standby generators; and • Internal combustion engines. For a more detailed listing, refer to the Technical Appendices, page 4-4, in the APCD's CEQA Air Quality Handbook (April 2012). (2) Air Quality Comments about Question b in Section 3. Air Quality of Initial Study. Construction Impacts On page 25 and 26 of the Initial Study, construction impacts for this project were evaluated using Table 2-2 in the APCD’s 2012 CEQA Handbook. In 2021, the APCD updated their Land Use and CEQA Webpage and concluded the best way to calculate construction impacts, after using Table 1-1, is through the use of the most up-to-date version of CalEEMod. The APCD recommends updating this section to reflect the analysis used in the Emissions Modeling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (Attachment 2 of the project’s Initial Study) as this report used CalEEMod to calculate construction emissions. Based on the analysis in Attachment 2, construction impacts would be below APCD thresholds with the assumption that Tier 3 off-road construction equipment would be used. Because of this assumption, the APCD recommends including a mitigation measure that states all off-road construction equipment shall be tier 3 or higher to be consistent with the Attachment 2 modeling assumptions and ensure emissions are below APCD thresholds. In addition, to manage fugitive dust emissions, the APCD supports mitigation measure AQ-2 and the APCD supports mitigation measures AQ 1,3,4, and 5 to meet state and federal requirements for this project. Comments about Question b in Section 3. Air Quality of Initial Study. Operational Impacts On page 26 of the Initial Study, operational impacts for this project were evaluated using “SLOAPCD’s operational screening criteria for air quality analyses” and the “project would not exceed the Page 542 of 1225 APCD Comments Regarding the SLO Airport Hotel Project May 24, 2021 Page 3 of 4 identified operational thresholds established by the SLOAPCD”. According to Table 1-1 in the APCD’s 2012 CEQA Handbook, this project would exceed the ROG+NOx 25lbs/day operational threshold as this project would exceed 177 rooms. Based on Table 1-1, this project would require mitigation. However, further analysis used in the Emissions Modeling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (Attachment 2) conclude the project would be below APCD operational thresholds. The APCD recommends updating this section to reflect the analysis used in Attachment 2 as this report used CalEEMod to calculate operational emissions which is a more refined analysis than Table 1-1. (3) Greenhouse Gas Emissions Comments about Question a in Section 8. GHG Emissions of Initial Study The Emissions Modeling Report for the San Luis Obispo Airport Hotels Project quantified the GHG emissions for the project in 2023 and 2030 and compared the GHG impacts to the service population threshold in the City of San Luis Obispo’s qualified Climate Action Plan. Mitigation measure GHG-1 provides a mechanism for the project to address lifetime GHG impacts in excess of the service population threshold. The APCD recognizes a service population threshold may not be the most applicable threshold choice for projects like hotels that have relatively low numbers of employees relative to project GHG emissions. After GHG reductions are quantified from on-site and other potential mitigation measures, the APCD recommends quantifying annual impacts over the life of the project to also account for reduction in project impacts due to future emission reduction technology that is included in CalEEMod, the emission modeling tool used by AMBIENT Air Qua lity & Noise Consulting. The APCD developed the 2021 Interim CEQA Greenhouse Gas Guidance document to provide administrative clarification on the SLO County APCD Handbook’s thresholds of significance for GHG emissions and to provide information on current trends, best practices, and legislation. This document includes a hierarchy of GHG mitigation measures the project can consider addressing its excess impacts. If additional GHG emission calculations are to be accomplished, the project may consider using the near-term release of the updated CalEEMod model, using current and future GHG intensity factors from 3CE. Comments about Question b in Section 8. GHG Emissions of Initial Study The guidance in the APCD’s Interim CEQA GHG document should be used to compare the project to existing applicable plans, policies, or regulations that have been legally adopted for the purpose of reducing GHG emissions. In addition to comparing the project to the City of San Luis Obispo’s Climate Action Plan, the APCD recommends comparing the project to the: • San Luis Obispo Council of Governments Regional Transportation Plan/Sustainable Community Strategies (RTP/SCS): Project proponents should work with SLOCOG early in the project development process to foster consistency with the land use and transportation policies, goals, action strategies, and preferred growth scenario identified in the current RTP/SCS; and • Demonstrate project consistency with the 2017 Scoping Plan; All applicable components within the 2017 Scoping Plan should be evaluated for consistency. One such component is transportation: Page 543 of 1225 APCD Comments Regarding the SLO Airport Hotel Project May 24, 2021 Page 4 of 4 o In the GHG section of a project’s CEQA evaluation, a project can demonstrate it is consistent with the transportation GHG reduction assumptions in the 2017 Scoping Plan if it can show 15% vehicle miles traveled (VMT) reduction. o Projects which cannot achieve 15% VMT reduction need to demonstrate how they will achieve equivalent GHG reductions by implementing design changes or other offsetting GHG mitigation to comply with the 2017 Scoping Plan. o Note: SB 743 recommends a project achieve 15% VMT reduction and is evaluated in the transportation section of a project’s CEQA evaluation. The difference between SB 743 and the 2017 Scoping Plan is SB 743 recommendation can only be met by VMT reductions, whereas the 2017 Scoping Plan consistency can be achieved with VMT reductions and design changes or other offsetting GHG mitigation equivalent to 15% VMT reduction. Again, thank you for the opportunity to comment on this proposal. If you have any questions or comments, feel free to contact me at (805) 781-5912.

Likewise, we appreciate the opportunity to provide comments regarding those aspects of the Project that CDFW, by law, may be required to carry out or approve through the exercise of its own regulatory authority under the Fish and Game Code. CDFW ROLE CDFW is California’s Trustee Agency for fish and wildlife resources and holds those resources in trust by statue for all the people of the State (Fish & G. Code, §§ 711.7, subd. (a) & 1802; Pub. Resources Code, § 21070; CEQA Guidelines § 15386, subd. (a)). CDFW, in its trustee capacity, has jurisdiction over the conservation, protection, and management of fish, wildlife, native plants, and habitat necessary for biologically sustainable populations of those species (Id., § 1802). Similarly, for purposes of CEQA, CDFW is charged by law to provide, as available, biological expertise during public agency environmental review efforts, focusing specifically on 1 CEQA is codified in the California Public Resources Code in section 21000 et seq. The “CEQA Guidelines” are found in Title 14 of the California Code of Regulations, commencing with section 15000.

CDFW is also submitting comments as a Responsible Agency under CEQA (Pub. Resources Code, § 21069; CEQA Guidelines, § 15381). CDFW expects that it may need to exercise regulatory authority as provided by the Fish and Game Code. As proposed, for example, the Project may be subject to CDFW’s lake and streambed alteration regulatory authority (Fish & G. Code, § 1600 et seq.). Likewise, to the extent implementation of the Project as proposed may result in “take” as defined by State law of any species protected under the California Endangered Species Act (CESA) (Fish & G. Code, § 2050 et seq.), related authorization as provided by the Fish and Game Code may be required. PROJECT DESCRIPTION SUMMARY Proponent: Sunsmit, LLC Objective: The objective of the Project is to construct a dual-branded hotel in the vicinity of the San Luis Obispo Airport, with a total disturbance size of 5.04 acres. Primary Project activities include construction of the hotel which is approximately 125,000 square feet, 214 parking spaces, and 219,570 square feet of landscaping. Location: 950 and 990 Aero Drive, San Luis Obispo, California 93401. APN 053-412- 010 & 053-412-011 Timeframe: Work will begin March 2022, for 20 months. COMMENTS AND RECOMMENDATIONS CDFW offers the comments and recommendations below to assist City of San Luis Obispo, Community Development Department in adequately identifying and/or mitigating the Project’s significant, or potentially significant, direct and indirect impacts on fish and wildlife (biological) resources. Editorial comments or other suggestions may also be included to improve the document. Oct 3, 2019 The unnamed ephemeral drainage and associated wetland habitat has the potential to support species of special concern. These resources may need to be evaluated and addressed prior to any approvals that would allow ground -disturbing activities or land use changes. The MND indicates there is potentially significant impact unless mitigation measures are taken but the measures listed are general and non-specific and/or may be inadequate to reduce impacts to less than significant . CDFW is DocuSign Envelope ID: C0CEC2EF-72FD-4F71-813E-704A9F6CB1A7 Page 546 of 1225 Shawana Scott, Senior Planner City of San Luis Obispo, Community Development Department May 24th, 2021 Page 3 concerned regarding potential impacts to special-status species including, but not limited to: California Rare Plant Ranked (CRPR) 1B.1 Hoover’s button-celery (Eryngium aristulatum var. hooveri), and the state rare and CRPR 1B.1 Adobe sanicle (Sanicula maritima). In order to adequately assess any potential impacts to biological resources, focused biological surveys should be conducted by a qualified wildlife botanist during the appropriate survey period(s) in order to determine whether any special-status species and/or suitable habitat features may be present within the Project area. Properly conducted biological surveys, and the informat ion assembled from them, are essential to identify any mitigation, minimization, and avoidance measures and/or the need for additional or protocol-level surveys, especially in the areas not in irrigated agriculture, and to identify any Project-related impacts under CESA and other species of concern. I. Environmental Setting and Related Impact Would the Project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by CDFW or the United States Fish and Wildlife Service (USFWS)? COMMENT 1: Special-Status plants Issue: The Project site contains habitat suitable to support special-status plant species meeting the definition of rare or endangered under CEQA Guidelines Section 15380 including, but not limited to, CRPR 1B.1 Hoover’s button-celery (Eryngium aristulatum var. hooveri), and the State designated rare and CRPR 1B.1 Adobe sanicle (Sanicula maritima). Although there was a preliminary field study done on October 3rd, 2019 that did not find any rare plants, that study was outside of the blooming period where the plants could have been identified. Specific impact: Without appropriate avoidance and minimization measures for special-status plants, potential significant impacts resulting from ground- and vegetation-disturbing activities associated with Project construction include inability to reproduce and direct mortality. Evidence impact would be significant: Special-status plant species known to occur in the vicinity of the Project site are threatened by residential development, road maintenance, vehicles, grazing, trampling, and invasive, non-native plants (CNPS 2021). Recommended Potentially Feasible Mitigation Measure(s) To evaluate potential impacts to special-status plant species associated with the Project, CDFW recommends conducting the following evaluation of the Project area , DocuSign Envelope ID: C0CEC2EF-72FD-4F71-813E-704A9F6CB1A7 Page 547 of 1225 Shawana Scott, Senior Planner City of San Luis Obispo, Community Development Department May 24th, 2021 Page 4 editing the MND to include the following additional measures , and including the following mitigation measures as conditions of approval. Recommended Mitigation Measure 1: Special-Status Plant Surveys If suitable habitat is present, CDFW recommends that the Project site be surveyed for special-status plants by a qualified botanist following the “Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities” (CDFW 2018). This protocol, which is intended to maximize detectability, includes the identification of reference populations to facilitate the likelihood of field investigations occurring during the appropriate floristic period. In the absence of protocol-level surveys being performed, additional surveys may be necessary. Recommended Mitigation Measure 2: Special-Status Plant Avoidance CDFW recommends that special-status plant species be avoided whenever possible by delineating and observing a no-disturbance buffer of at least 50 feet from the outer edge of the plant population(s) or specific habitat type(s) required by special -status plant species. If buffers cannot be maintained, then consultation with CDFW is warranted to determine appropriate minimization and mitigation measures for impacts to special - status plant species. Recommended Mitigation Measure 3: State-listed Plant Take Authorization If a plant species listed pursuant to CESA or State designated as rare is identified during botanical surveys, consultation with CDFW is warranted to determine if the Project can avoid take. If take cannot be avoided, take authorization prior to any ground-disturbing activities may be warranted. Take authorization would occur through issuance of an ITP by CDFW, pursuant to Fish and Game Code section 2081 subdivision (b) for State listed threatened or endangered plants or pursuant to the Native Plant Protection Act and Fish and Game Code section 1900 et seq. for State designated rare plants. II. Editorial Comments and/or Suggestions Lake and Streambed Alteration: The Project contains activities that may result in the Project site being subject to CDFW’s regulatory authority pursuant Fish and Game Code section 1600 et seq. Fish and Game Code section 1602 requires an entity to notify CDFW prior to commencing any activity that may (a) substantially divert or obstruct the natural flow of any river, stream, or lake; (b) substantially change or use any material from the bed, bank, or channel of any river, stream, or lake; or (c) deposit debris, waste or other materials that could pass into any river, stream, or lake. “Any river, stream, or lake” includes those that are ephemeral or intermittent, such as the unnamed stream within the Project site, as well as those that are perennial in nature.

The State of California and Federal Highways Administration designate SLOCOG as the Regional Transportation Planning Agency (RTPA) and the Metropolitan Planning Organization (MPO), respectively, for the region. While SLOCOG does not have permit or regulatory authority for land use proposals, SLOCOG is responsible for planning the long-term viability of the regional surface transportation system and for programming funds to achieve the objectives of the adopted Regional Transportation Plan (RTP) and Sustainable Communities Strategy (2019 RTP/SCS). SLOCOG’s Edna-Price Canyon Trail Feasibility Study and the State Route 227 Operations Study assessed bicycle and pedestrian infrastructure concepts and intersection operational improvements at several locations identified in the project’s Multimodal Transportation Impact Study (MMTIS), including Farmhouse Lane, Buckley Road and segments along the SR 227 corridor. The SR 227 Operational Study assessed roundabouts at Farmhouse Lane/SR 227 and Buckley Road/SR 227 to be the preferred intersection controls and the County of San Luis Obispo is conducting an Intersection Control Evaluation Step 2 Analysis to verify the assessment or recommend other alternatives. The intersection of SR 227 and Buckley Road currently operates at unacceptable service levels and construction of an operational improvement is expected within 3-5 years, while improvements at Farmhouse Lane are in subsequent phases. The Edna-Price Canyon Trail Feasibility Study identifies a Class I shared use path on the west side of SR 227 between Los Ranchos Road and Tank Farm Road, a portion of which coincides with Class IV protected bike lanes along Broad Street identified in the City’s Active Transportation Plan. There are no pedestrian facilities on the west side of Broad Street/SR 227 between Airport Drive and Buckley Road and few driveways or potential crossing conflicts. Los Ranchos Elementary School is located less than 2 miles south of the City on the west side of the 227 corridor and serves neighborhoods in southern San Luis Obispo. SLOCOG encourages the City and County to coordinate with regard to the in-progress ICE Step 2 Analysis for the SR 227 intersection at Farmhouse Lane and incorporate the final build alternative into City planning documents. The intersection operational improvement should incorporate safe pedestrian and bicycle crossings that allow access from the bi-directional Class I shared use path on the west side of SR 227 to the northbound Class IV bike lanes on the east side of SR 227. SLOCOG recommends that impacts from this project to the SR 227 corridor are considered. An appropriate payment toward the City’s TIF to construct the operational improvement at Buckley Road/SR 227 and the segment of the Edna-Price Canyon Trail between Buckley Road and Farmhouse Lane should also be considered.

Project Title: SLO Airport Hotel Project 2. Lead Agency Name and Address: City of San Luis Obispo 919 Palm Street San Luis Obispo, CA 93401 3. Contact Person and Phone Number: Shawna Scott, Senior Planner (805) 781-7176 4. Project Location: 950 & 990 Aero Drive (APN 053-412-010 & 053-412-011), San Luis Obispo, CA (project site) 5. Project Sponsor’s Name and Address: Sunsmit, LLC Attn: Sanjay Ganpule 280 Foxtail Lane Templeton, CA 93465 6. General Plan Designations: Business Park 7. Zoning: Business Park-Specific Plan (BP-SP) Airport Area Specific Plan, Safety Area S-1C (AASP) 8. Description of the Project: The proposed project includes the construction and operation of a new dual-branded three-story hotel with surface parking on a site comprised of approximately 5.04 acres located at 950 and 990 Aero Drive (APNs 053-412-010 and 053-412-011) in the city of San Luis Obispo, California (Figures 1 and 2). The project site is located at the corner of Aero Drive and Broad Street (Highway 227) and bordered by the San Luis Obispo County Regional Airport to the south and west. The property is zoned Business Park (BP), within the Airport Area Specific Plan (AASP), and within the Airport Land Use Planning Area zones 4 and 5. The new hotel would consist of two buildings (Building A and Building B) with 204 guest rooms, guest amenities such as an outdoor patio and dining area, meeting space, fitness room, breakfast area, and bar. The proposed hotel would be approximately 125,000 square feet with a maximum height of 45 feet for occupied buildings and 52 feet for non-occupied space. The development would provide 214 vehicle parking spaces, including eight accessible parking spaces, 18 clean air/vanpool parking spaces, 20 electric vehicle (EV)-ready parking spaces, 51 EV-capable Page 555 of 1225 CITY OF SAN LUIS OBISPO 2 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 parking spaces, 12 motorcycle parking spaces, 22 bicycle parking spaces, and one loading space pursuant to City Zoning Regulations 17.72.040. The project also includes 219,570 square feet of landscaping. Plans for the project are illustrated in Figures 3 through 5. Project construction would require approximately 10,000 cubic yards (cy) of cut and 8,900 cy of fill for a total of 18,900 cy of earthwork. Construction is anticipated to last approximately 20 months, beginning in March 2022. Construction would result in approximately 4.33 acres of ground disturbance and approximately 1.8 acres of impervious pavement. Construction would require a scraper, water truck, backhoe, compactor, and skip loader for grading activities; a telescopic forklift and skid steer for building construction; and a skip loader, grader, compactor, and asphalt paver for paving activities. The proposed project would result in a Floor Area Ratio (FAR) of 0.58 (127,200/219,570). The project site is in the BP zone within the AASP, which allows for a maximum building height of 45 feet for occupied buildings, up to 52 feet for non-occupied architectural features,1 a maximum lot coverage of 75%, and a maximum FAR of 0.6. The proposed three-story hotel would be designed with contemporary materials, architectural reliefs, and distinguishing color combinations. The architectural style of the hotel would combine the “airport architecture” with hotel architecture. Metal awnings, metal trellises, and low planter walls would create appealing dining and meeting places. A mix of trees, bushes, and groundcovers varying in textures, colors, form, and height would enhance the development and patio and outdoor areas. Access to the project site would be provided via a new driveway 300 feet west of the Broad Street/Aero Drive intersection and a porte cochère is proposed to allow traffic flow within the parking area for guest registration and parking. Visual simulations have been prepared by the applicant for the proposed project and are shown on Figures 6a through 6g. The proposed development program details are summarized in Table 1, and the project site plans are included as Attachment 1. Table 1.

Due to the nature of the hotel business, loading spaces are not critical. An exception to City Zoning Regulation 17.72.100 to reduce the required three loading spaces to one space is requested. Additionally, the signage proposed on the hotel would be placed above the architectural reliefs at the entry and in strategic locations (see Figures 6a through 6g). Placing the signage at these locations would require 1 Airport Area Specific Plan Table 4.9: San Luis Obispo Airport Area Specific Plan Maximum Building Height Standards Page 556 of 1225 CITY OF SAN LUIS OBISPO 3 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 the signage to exceed the 25-foot height limit.2 The signage would be attached to the building, not free standing. An exception to the height limit identified in AASP Sign Standards Goal 5.18.1 is being requested for this project. Water service for the proposed project would be provided by the City’s Utilities Department and the project would require a total annual water demand of approximately (87.72 acre-feet). The project would be served by the City’s sewer system and would include the installation of a new sewer lateral to connect to existing City sewer infrastructure. Estimated average dry weather flow would be 14,280 gallons per day (City of San Luis Obispo 2020). The project site is in the AASP area of the city and is generally surrounded by one- and two-story commercial office uses and a few remaining unimproved parcels. The San Luis Obispo Regional Airport is located less than 500 feet southwest of the project site, and residential subdivisions are prominent northeast of the project site across Broad Street (e.g., along Goldenrod Lane approximately 700 feet northeast). The project site currently consists of one unimproved, unoccupied parcel and a second parcel previously used as an overflow parking area that the project sponsor is requesting to be merged as part of the proposed project. The proposed project site consists of ruderal herbaceous vegetation and non-native trees in the western portion of the site, which has been previously disturbed and consistently mowed since the early 2000s. The project site is located within the San Luis Obispo Creek watershed, approximately 2 miles east of the East Fork of the San Luis Obispo Creek. The project area is characterized by flat to gently sloping land with a steep slope located at the southwest edge of the parcel. There is an unnamed drainage bordering the site that flows generally northwest across the southwestern portion of the project area. The drainage enters the area through a culvert under Aero Drive and flows west along the edge of the project area before making a 90-degree bend and continuing north–northwest for approximately 400 feet, where it flows into a 36-inch culvert in the northwest corner of the project area. The drainage is ephemeral, conveying surface flows from the project parcel and adjacent developments during periods of significant rainfall. The proposed project includes a 35-foot-wide setback from jurisdictional aquatic features located in the southern and western portions of the site. Since the project site is currently unimproved and allows for the infiltration of stormwater at the site, the project would install a storm drain system, including a catch basin and detention system. A water line, water meter, fire line, and fire hydrant are also proposed. During operation, a maximum of 604 people would be on-site. On a typical day, the project would be expected to generate an average of 1,822 daily weekday trips, of which 102 would occur during the a.m. peak hour and 131 during the p.m. peak hour. The proposed project’s potential for cumulatively considerable impacts has been evaluated in Section 21, Mandatory Findings of Significance. 9. Project Entitlements: Major Development Review Conditional Use Permit 10. Surrounding Land Uses and Settings: Surrounding uses and stories of surrounding buildings are summarized below: • Northeast: one- and two-story commercial offices and buildings • Northwest: one- and two-story commercial office buildings and restaurant buildings (i.e., SLO Brew Rock) • Southwest: ephemeral drainage, San Luis Obispo County Regional Airport, and ancillary features (i.e., Airport parking lot, buildings) • Southeast: one- and two-story commercial offices and buildings 2 City Municipal Code 15.40.070.A.1: The maximum height of wall signs on multi-story buildings is the uppermost point of the second story unless additional height is approved through a sign program or exception as provided in Sections 15.40.485 and 15.40.600.

Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code Section 21080.3.1? If so, is there a plan for consultation that includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? Native American Tribes were notified on December 11, 2020, about the project consistent with City and State of California regulations, including, but not limited to, Assembly Bill 52, and no tribe requested consultation. The Salinan Tribe responded to the consultation invitation with a request that: (1) if any resources are unearthed that all work to stop in the area until a qualified archaeologist can evaluate the find, and (2) if humans remains are unearthed that all work stop and State law be followed. This request has been incorporated into the Mitigation Monitoring and Reporting Program. 12.

Page 571 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 18 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 DETERMINATION (To be completed by the Lead Agency): On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. ☐ I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made, by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. ☒ I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. ☐ I find that the proposed project MAY have a “potentially significant” impact(s) or “potentially significant unless mitigated” impact(s) on the environment, but at least one effect (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed ☐ I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (1) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (2) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. ☐ April 6, 2021 Signature Date Shawna Scott, Senior Planner For: Michael Codron, Printed Name Community Development Director Page 572 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 19 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 EVALUATION OF ENVIRONMENTAL IMPACTS 1. A brief explanation is required for all answers except “No Impact” answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g., the project falls outside a fault rupture zone). A “No Impact” answer should be explained where it is based on project-specific factors as well as general standards (e.g., the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis). 2. All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3. Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. “Potentially Significant Impact’ is appropriate if there is substantial evidence that an effect may be significant. If there are one or more “Potentially Significant Impact” entries when the determination is made, an EIR is required. 4. “Negative Declaration: Less Than Significant with Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less than Significant Impact.” The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section 19, “Earlier Analysis,” as described in (5) below, may be cross- referenced). 5. Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration (Section 15063 (c) (3) (D)). In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are “Less than Significant with Mitigation Measures Incorporated,” describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they addressed site-specific conditions for the project. 6. Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7. Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8. The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance Page 573 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 20 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 1. AESTHETICS Except as provided in Public Resources Code Section 21099, would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Have a substantial adverse effect on a scenic vista? 1, 3 ☐ ☐ ☒ ☐ b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, open space, and historic buildings within a local or state scenic highway? 2, 4, 8 ☐ ☐ ☒ ☐ c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? 1, 3, 4, 5 ☐ ☐ ☒ ☐ d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? 1, 5 ☐ ☐ ☒ ☐ Evaluation The proposed project site is located in the AASP portion of the city and is surrounded by one- and two-story commercial offices and scattered restaurant buildings in all directions. The San Luis Obispo County Regional Airport is located less than 500 feet southwest of the project site. The project site consists of one unimproved, currently unoccupied parcel and a second parcel previously used as a parking lot that are proposed to be merged as part of the proposed project. The area is dominated by ruderal herbaceous vegetation and non-native trees in the western portion of the site. The project site has been previously disturbed and considerably altered through past land conversion. The project area is characterized by flat to gently sloping land with a steep slope located at the southwest edge of the site. There is an unnamed drainage that flows generally northwest across the southwestern portion of the project area. The topography of the city is generally defined by several low hills and ridges, such as Righetti Hill, Bishop Peak, and Cerro San Luis. These are three of the nine peaks known as the Morros and provide scenic focal points for much of the city. The project vicinity exhibits intermittent views of nearby natural landmarks, including Cerro San Luis. The terrain within the project site is relatively flat, with the elevation ranging from 157 to 162 feet above sea level. Based on the City’s Conservation and Open Space Element (COSE) map of scenic roadways and vistas, Broad Street, located adjacent to the eastern boundary of the project site, is designated as having high scenic value. The AASP identifies specific goals, policies, and design guidelines and standards intended to protect and enhance the visual quality and character of the AASP area and land uses with the BP land use designation. Policies in the AASP include, but are not limited to, maintaining community character and assuring a desirable setting for the types of businesses that are the primary reason for business parks. The BP land use designation is generally intended for well-designed, master-planned, campus-type developments that will contribute to community character and the City’s objective of attracting jobs that can support households within the city. The AASP Design Guidelines and Standards for the physical development and design of new projects within the Airport Area, include, but are not limited to, the following: • 5.1.1: Principal buildings shall be oriented parallel to the street. • 5.1.4: Buildings shall have architecturally articulated entry features facing the street. • 5.4.1: Parking lots shall be located at the rear or side of buildings, rather than between the front facade of the building and the street. Side parking shall not exceed 40% of the frontage of the lot on the primary street. • 5.4.4: Parking lots shall be planted with shade trees in a pattern and number that can be reasonably expected to shade at least 50% of the lot surface within ten (10) years of planting, and provide a nearly continuous canopy at maturity. • 5.6.1: Loading docks and refuse collection areas are not permitted in the area between the building and the street. Page 574 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 21 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 • 5.6.6: Rooftop mechanical equipment shall be screened by parts of the roof, or architecturally compatible screening features, so the equipment is not visible from the ground outside the site or open space areas to the public. On sites designated Business Park, such screening shall make rooftop equipment not visible from a viewpoint outside the site and at the same height as the equipment. • 5.10.1: Building facades visible from streets shall vary in modules of 20 meters (66 feet) or less. On any building facade, continuous wall planes longer than 30 meters (100 feet) should be avoided. Where interior functions require longer continuous spaces, exterior walls should have architectural features such as columns or pilasters at least every 20 meters. Such architectural features shall have a depth of at least 3 percent of the length of the facade, and shall extend at least 20 percent of the length of the façade. • 5.10.2: Facades that face public streets shall use elements such as arcades, awnings, entry features, windows, or other such animating features along at least 60 percent of their horizontal length. • 5.17.1: Development in the Airport Area is subject to the requirements of the City’s Public Art ordinance. • 5.18.1: Building identity signs shall be limited to major site entries from public roadways. Corporate and business identity signs can be placed on the buildings themselves, as long as they are located near the building entrance and are for identification within the site (i.e., not from public roadways). • 5.19.1: Provide minimum levels of lighting consistent with public safety standards along public roadways. • 5.19.4: To maintain a pedestrian scale and reduce ambient light levels, streetlights shall not exceed 20 feet on all other streets. • 5.19.7: Light fixtures shall be cut-off type fixtures that focus light down toward the ground and shield the light source from surrounding areas not intended to be illuminated. a) A scenic vista is generally defined as a high-quality view displaying good aesthetic and compositional values that can be seen from public viewpoints. A substantial adverse effect on a scenic vista would occur if the proposed project would significantly degrade the scenic landscape as viewed from public roads or other public areas. The project is located in an urbanized area of the AASP area with intermittent views of the Irish Hills to the west and the San Lucia Mountains and Foothills to the east. According to the AASP, scenic views from major roads within the AASP area should be preserved (Table 5.4, San Luis Obispo Airport Area Specific Plan, Roadway View Protection). Broad Street (north of Buckley Road) is identified as the closest roadway from which views should be preserved, though the AASP recognizes that views of the Irish Hills to the west are too distinct for views to be feasibly maintained while allowing reasonable foreground development. Based on the City’s COSE, the project site is not within the viewshed of a designated scenic vista. Views of the project site from Broad Street would be consistent with existing one- and two-story commercial buildings along the frontage of Broad Street. The proposed building would be similar in height and scale as existing adjacent buildings and the proposed building height would be consistent with the maximum building height allowed by the AASP. The project proponent has requested a modification to allow for hotel signage to exceed the 25-foot height limit at the entry and in other strategic locations (see Figures 6a through 6g), which is generally consistent with other hotel developments in the city outside of the Downtown Core. The project would not substantially obstruct views of the Irish Hills or San Lucia Mountains from Broad Street; therefore, potential impacts associated with adverse effects on a scenic vista would be less than significant. b) The project site is located approximately 2.47 miles east of U.S. Highway 101 (U.S. 101). Based on the California Department of Transportation (Caltrans) California Scenic Highways online mapping tool, this section of U.S. 101 is eligible for State scenic highway designation but is not officially designated. The City’s COSE also identifies Broad Street (approximately 375 feet east of the project site) as having high scenic value (see additional discussion, above [a]). The project site would not be visible to viewers travelling along U.S. 101 due to the distance between U.S. 101 and the project site, as well as the presence of intervening vegetation and development. The project would not substantially damage scenic resources within a local or state scenic highway; therefore, potential impacts would be less than significant. c) As discussed previously, the project site is located in an urbanized area and is zoned Business Park-Specific Plan (BP-SP) within the AASP. The proposed project must comply with the City’s AASP Design Guidelines and was conceptually reviewed by the City’s ARC on March 18, 2019, for consistency with the AASP Design Guidelines and Community Page 575 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 22 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Design Guidelines. The ARC generally supported the phased project and the conceptual site design with a few suggestions for design modifications. Following the ARC meeting and conceptual review of the project design, the project was revised to avoid impacts to wetland resources in the western portion of the project area and the two hotels were combined into one building (dual-brand hotel). The project as currently proposed would not conflict with applicable zoning and other regulations governing scenic quality; therefore, impacts would be less than significant. d) Existing sources of nighttime lighting in the vicinity of the project site include airport-related lighting, spillover parking lot lighting from nearby commercial office buildings, interior lighting emanating from nearby commercial parking lot lighting, and intermittent vehicle lighting from vehicles traveling along Aero Drive, Broad Street, and/or parking at the nearby commercial office buildings. The project is required to comply with the City’s AASP Design Guidelines pertaining to lighting and the Lighting and Night Sky Preservation Ordinance (17.70.100) standards for outdoor lighting and new development, which include, but are not limited to, requirements for new outdoor light sources to be shielded and directed away from adjacent properties and public rights-of-way, requirements for minimum levels of lighting consistent with public safety standards, and limits to hours of lighting operation. Therefore, impacts from new sources of light or glare would be less than significant. Mitigation Measures Mitigation measures are not required. Conclusion The project is not located within a scenic vista or within the viewshed of a designated scenic highway and would not be highly visible from nearby public roadways designated as having high scenic value. The project has been designed to comply with all applicable standards set forth in the AASP and the City’s Community Design Guidelines. No potentially significant impacts associated with aesthetic resources would occur and mitigation measures are not required. 2. AGRICULTURE AND FORESTRY RESOURCES In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? 7 ☐ ☐ ☐ ☒ b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? 3, 7, 8 ☐ ☐ ☐ ☒ Page 576 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 23 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g))? 3, 8 ☐ ☐ ☐ ☒ d) Result in the loss of forest land or conversion of forest land to non-forest use? 3, 8 ☐ ☐ ☐ ☒ e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? 3, 8 ☐ ☐ ☐ ☒ Evaluation The California Department of Conservation (DOC) classifies and maps agricultural lands in the state in the Farmland Mapping and Monitoring Program (FMMP). The FMMP identifies five farmland categories: Prime Farmland, Farmland of Statewide Importance, Unique Farmland, Farmland of Local Importance, and Farmland of Local Potential. The project site is designated as Urban and Built-Up Land by the FMMP. The project site is zoned as BP-SP within the City’s AASP area. The project site is not located within or immediately adjacent to land zoned for agricultural uses, land under an active Williamson Act contract, or land currently supporting agricultural uses. a) According to Public Resources Code (PRC) Section 12220(g), forest land is defined as land that can support 10% native tree cover of any species, including hardwoods, under natural conditions, and that allows for management of one or more forest resources, including timber, aesthetics, fish and wildlife, biodiversity, water quality, recreation, and other public benefits. Timberland is defined as land, other than land owned by the federal government and land designated by the State Board of Forestry and Fire Protection as experimental forest land, which is available for, and capable of, growing a crop of trees of a commercial species used to produce lumber and other forest products, including Christmas trees. The project site does not support any forest land or timberland and is not surrounded by forest land or timberland. According to the FMMP, the project site and surrounding land uses are designated as urban and built-up land (DOC 2020). Since the project site is not located on or adjacent to designated Farmland, the project would not result in the conversion of Farmland to non-agricultural use and no impacts would occur. b) The project site is not located within an Agricultural Zone and is not located within or immediately adjacent to land under an active Williamson Act contract. Therefore, the project would not conflict with existing agricultural zoning or a Williamson Act contract and no impacts would occur. c, d) The project site does not include land use designations or zoning for forest land or timberland. Additionally, the project site does not contain 10% tree cover that would classify the site as forest land. Therefore, the project would not conflict with zoning for, result in the loss of, or result in the conversion of forest land, timberland, or timberland zoned Timberland Production and no impacts would occur. e) The project includes construction of a new hotel building and associated parking in the City’s AASP area. The project site is surrounded by urbanized commercial uses. The nearest agricultural uses are approximately 0.75 mile west and southeast of the project site. The proposed project would be consistent with surrounding uses and with existing zoning designated for the project site and would not adversely affect agricultural water supplies or other agricultural support facilities. Therefore, the project would not result in substantial changes in the environment that could result in conversion of nearby agricultural land or forest land to non-agricultural or non-forest use and no impacts would occur. Page 577 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 24 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Mitigation Measures Mitigation measures are not required. Conclusion The project site is located in an urbanized area and is not within or adjacent to Farmland, land zoned for agricultural or forest land use, or land under a Williamson Act contract. No potentially significant impacts to agriculture or forest land would occur and mitigation measures are not required. 3. AIR QUALITY Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Conflict with or obstruct implementation of the applicable air quality plan? 2, 9, 10, 11, 12 ☐ ☐ ☒ ☐ b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? 2, 9, 11 ☐ ☒ ☐ ☐ c) Expose sensitive receptors to substantial pollutant concentrations? 2, 11, 14, 15 ☐ ☒ ☐ ☐ d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? 2, 11, 15 ☐ ☒ ☐ ☐ Evaluation This evaluation is based, in part, on the Emissions Modelling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (included as Attachment 2). a) The city of San Luis Obispo is located within the South Central Coast Air Basin (SCCAB), which also includes Santa Barbara and Ventura Counties. Air quality within the SCCAB is regulated by several jurisdictions, including the U.S. Environmental Protection Agency (EPA), California Air Resources Board (CARB), and the San Luis Obispo County Air Pollution Control District (SLOAPCD). San Luis Obispo County is currently designated as “nonattainment” for the state standards for ozone, partial nonattainment (in eastern San Luis Obispo County, outside of the project area) for federal ambient standards for ozone, and nonattainment for the state standards for particulate matter 10 microns or less in diameter (PM10). The City’s COSE identifies goals and policies to achieve and maintain air quality that supports health and enjoyment for those who live, work, and visit the city. These goals and policies include meeting federal and state air quality standards, reducing dependency on gasoline- or diesel-powered motor vehicles and to encourage walking, biking, and public transit use. The SLOAPCD has developed a CEQA Air Quality Handbook (most recently updated with a November 2017 Clarification Memorandum) to evaluate project-specific impacts and determine if potentially significant impacts could result from a project. To evaluate long-term emissions, cumulative effects, and establish countywide programs to reach acceptable air quality levels, a Clean Air Plan (adopted 2002) has been adopted by the SLOAPCD. Some land uses are considered more sensitive to changes in air quality than others, depending on the population groups and the activities involved. The CARB has identified the following groups who are most likely to be affected by air pollution (i.e., sensitive receptors): children under 14, the elderly over 65 years of age, athletes, and people with cardiovascular and chronic respiratory diseases. The nearest sensitive receptors to the project site are the single-family residences located approximately 540 feet northeast of the project site. Page 578 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 25 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Naturally Occurring Asbestos (NOA) has been identified as a toxic air contaminant by the CARB. Any ground disturbance proposed in an area identified as having the potential to contain NOA must comply with the CARB Airborne Toxics Control Measure (ATCM) for Construction, Grading, Quarrying, and Surface Mining Operations. The SLOAPCD Naturally Occurring Asbestos Map indicates that the project site is located within an area identified as having a potential for NOA to occur. In order to be considered consistent with the 2001 San Luis Obispo County Clean Air Plan (2001 CAP), a project must be consistent with the land use planning and transportation control measures and strategies outlined in the 2001 CAP. The project proposes infill development within the AASP area consistent with existing General Plan land use and zoning designations. The project would be easily accessible by Class II bicycle lanes on Broad Street and would include adequate secure bicycle storage, showers on-site, and posting and distribution of public transportation information (consistent with City regulations) to encourage employees to use alternative modes of transportation. The hotel would also provide a shuttle service for guests to the city’s downtown area to encourage alternate modes of transportation. The project would, therefore, be consistent with the land use policies identified in the 2001 CAP that encourage cities to develop at higher densities and encourage growth within their respective urban reserve lines to reduce overall vehicle trips and travel distances. Transportation Control Measures (TCMs) are controls implemented at the local or regional level to reduce emissions resulting from the use of motor vehicles. TCMs are primarily intended to reduce vehicle use by promoting and facilitating the use of alternative transportation options. Many of the TCMs identified within the 2001 CAP are not applicable to the project, such as campus trip reduction programs, local and regional public transportation improvements, motor vehicle inspection programs, and maintenance and development of park-and-ride lots throughout the county. The project proposes infill development within the AASP area and would include a variety of features that would be consistent with the TCMs in the 2001 CAP, including pedestrian- and bicycle-friendly site design, compact infill development within the City’s existing urban reserve line, and accessibility to an existing San Luis Obispo Transit stop along Broad Street southbound on Aero Drive, approximately 350 feet east of the project site. The project would be consistent with the 2001 CAP TCM to promote bicycle use through provision of on-site bicycle parking and connectivity to the regional bicycle network, bicycle storage, showers, lockers, and changing room facilities to encourage project employees to bike to and from work. The project site is located within immediate proximity of Class II bicycle lanes on Broad Street, as identified in the City of San Luis Obispo Bicycle Transportation Plan. The project would therefore be consistent with the land use policies and TCMs identified in the 2001 CAP that encourage cities to develop at higher densities and encourage growth within their respective urban reserve lines to reduce overall vehicle trips and travel distances. Potential impacts related to a conflict with an air quality plan would be less than significant. b) San Luis Obispo County is currently designated as non-attainment for ozone and PM10 under state ambient air quality standards. Construction of the project would result in emissions of ozone precursors including reactive organic gasses (ROG), nitrous oxides (NOx), and fugitive dust emissions (PM10). During operation, the project would result in emissions of ozone precursors associated with mobile source emissions and other stationary sources. Construction Emissions The project would result in the disturbance of approximately 5.04 acres and would require approximately 10,000 cy of cut and 8,900 cy of fill for a total of 18,900 cy of total earthwork. This would result in the generation of construction dust as well as short- and long-term construction vehicle emissions, including diesel particulate matter (DPM), ROG, NOx, and PM10. Based on the screening emission rates for construction operations in the SLOAPCD CEQA Air Quality Handbook, as shown in Table 2, and assuming a reasonable worst-case scenario of earth movement for the proposed hotel, the project’s construction emissions would not exceed the SLOAPCD’s applicable threshold for ROG/NOx, DPM, or PM10. Table 2. Screening Emission Rates for Project Construction Criteria Pollutant Total Project Emissions SLOAPCD Threshold Exceeds Threshold? Reactive Organic Gases (ROG) + Nitrogen Oxides (NOx) 65.11 lbs/day 137 lbs/day No Diesel Particulate Matter (DPM) 2.73 lbs/day 7 lbs/day No Fugitive Particulate Matter (PM10) 0.22 ton/quarter 2.5 tons/quarter No Page 579 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 26 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Short-term construction emissions associated with the proposed project were calculated using the California Emission Estimator Model (CalEEMod), version 2016.3.2, computer program (AMBIENT Air Quality & Noise Consulting 2021). Emissions were quantified based on the default construction schedules, equipment use, and construction vehicle trips contained in the model. Construction emissions modeling assumptions are summarized in Attachment 2. Construction- generated emissions, without implementation of fugitive dust control measures, are summarized in Table 2 (see Tables 1 through 3 in Attachment 2). Table 2. Construction Emissions Summary Criteria Pollutant Highest Daily/Quarterly Emissions APCD Threshold Exceeds Threshold? Uncontrolled Daily Construction Emissions – Summer Conditions Reactive Organic Gases (ROG) + Nitrogen Oxides (NOx) 65.11 lbs/day 137 lbs/day No Diesel Particulate Matter (DPM) 1.41 lbs/day 7 lbs/day No Uncontrolled Daily Construction Emissions – Winter Conditions Reactive Organic Gases (ROG) + Nitrogen Oxides (NOx) 63.22 lbs/day 137 lbs/day No Diesel Particulate Matter (DPM) 1.29 lbs/day 7 lbs/day No Uncontrolled Quarterly Construction Emissions Reactive Organic Gases (ROG) + Nitrogen Oxides (NOx) 0.78 ton/quarter 2.5 tons/quarter No Diesel Particulate Matter (DPM) 0.03 ton/quarter 0.13 ton/quarter No Fugitive Dust (PM10) 0.15 ton/quarter 2.5 tons/quarter No Notes: Off-site mobile source emissions include EMFAC off-model adjustment factors for SAFE vehicle rule. Does not include fugitive dust controls. Based on default off-road vehicle fleet. Highest quarterly emissions assumes arch. coating, paving, and building construction activities could potentially overlap during one quarter. Architectural coating includes the use of low-VOC content architectural paints with VOC content of 50 g/L or less. Source: AMBIENT Air Quality & Noise Consulting 2021 As shown, estimated daily and quarterly construction emissions would not exceed SLOAPCD’s recommended thresholds of significance.The project does not exceed SLOAPCD screening emission rates for construction activities. However, SLOAPCD’s CEQA Air Quality Handbook recognizes special conditions, such as proximity to sensitive receptors, that require implementation of standard construction mitigation measures to reduce diesel idling (DPM) and fugitive dust. Due to the project’s proximity to surrounding residential areas (less than 1,000 feet), standard measures for reducing DPM and fugitive dust are required and have been included as Mitigation Measures AQ-1 and AQ-2. Therefore, potential air quality impacts associated with project construction would be less than significant with mitigation. Operational Impacts Implementation of the project would result in an increase in vehicle trips, energy use, and architectural coating off-gassing that would generate criteria pollutant emissions. Based on the SLOAPCD’s operational screening criteria for air quality analyses, the project would not exceed the identified operational thresholds established by the SLOAPCD (Table 3).

Construction activities such as excavation, grading, vegetation removal, staging, and building construction would result in temporary construction vehicle emissions and fugitive dust that may affect surrounding sensitive receptors. Based on the SLOAPCD CEQA Air Quality Handbook, construction activities within 1,000 feet of sensitive receptors require standard dust and DPM reduction measures. Mitigation Measures AQ-1 and AQ-2 have been identified to reduce exposure of sensitive receptors to adverse construction vehicle emissions and fugitive dust; therefore, impacts would be less than significant with mitigation. d) Construction of the proposed project would generate odors associated with construction smoke, dust, and equipment exhaust and fumes. The proposed construction activities would not differ significantly from those resulting from any other type of construction project. Any effects would be short-term in nature and limited to the construction phase of the proposed project. The SLOAPCD Naturally Occurring Asbestos Map indicates the project site is located within an area identified as having a potential for NOA to be present. The project would include approximately 18,900 cy of total earthwork, removal of low- lying vegetation, and construction of the proposed development. Pursuant to SLOAPCD requirements and the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations (CARB ATCM Section 93105), the applicant is required to provide geologic evaluation prior to any construction activities and comply with existing regulations regarding NOA, if present. Mitigation Measures AQ-3 and AQ-4 have been identified to require the applicant to complete a geologic evaluation and follow all applicable protocol and procedures if NOA is determined to be present on-site. The applicant is also required to comply with SLOAPCD regulations related to materials containing asbestos (Mitigation Measure AQ-5). Based on compliance with identified mitigation and existing regulations, potential impacts associated with other emissions would be less than significant with mitigation. Mitigation Measures AQ-1 During all construction activities and use of diesel vehicles, the applicant shall implement the following idling control techniques: 1. Idling Restrictions Near Sensitive Receptors for Both On- and Off-Road Equipment a. Staging and queuing areas shall not be located within 1,000 feet of sensitive receptors if feasible; b. Diesel idling within 1,000 feet of sensitive receptors shall not be permitted; c. Use of alternative fueled equipment shall be used whenever possible; and d. Signs that specify the no idling requirements shall be posted and enforced at the construction site. 2. California Diesel Idling Regulations. On-road diesel vehicles shall comply with Section 2485 of Title 13 of the California Code of Regulations. This regulation limits idling from diesel-fueled commercial motor vehicles with gross vehicular weight ratings of more than 10,000 pounds and licensed for operation on highways. It applies to California and non-California based vehicles. In general, the regulation specifies that drivers of said vehicles: a. Shall not idle the vehicle’s primary diesel engine for greater than 5 minutes at any location, except as noted in Subsection (d) of the regulation; and, b. Shall not operate a diesel-fueled auxiliary power system (APS) to power a heater, air conditioner, or any ancillary equipment on that vehicle during sleeping or resting in a sleeper berth for greater than 5.0 minutes at any location when within 1,000 feet of a restricted area, except as noted in Subsection (d) of the regulation. Signs must be posted in the designated queuing areas and job sites to remind drivers of the 5-minute idling limit. The specific requirements and exceptions in the regulation can be reviewed at the following website: www.arb.ca.gov/msprog/truck-idling/2485.pdf. Page 582 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 29 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 AQ-2 During all construction and ground-disturbing activities, the applicant shall implement the following particulate matter control measures and detail each measure on the project grading and building plans: 1. Reduce the amount of disturbed area where possible. 2. Use water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site and from exceeding San Luis Obispo County Air Pollution Control District (SLOAPCD) limit of 20% opacity for no greater than 3 minutes in any 60-minute period. Increased watering frequency shall be required whenever wind speeds exceed 15 miles per hour (mph) and cessation of grading activities during periods of winds over 25 mph. Reclaimed (non-potable) water is to be used in all construction and dust-control work. 3. All dirt stockpile areas (if any) shall be sprayed daily and covered with tarps or other dust barriers as needed. 4. Permanent dust control measures identified in the approved project revegetation and landscape plans shall be implemented as soon as possible, following completion of any soil-disturbing activities. 5. Exposed grounds that are planned to be reworked at dates greater than one month after initial grading shall be sown with a fast germinating, non-invasive, grass seed and watered until vegetation is established. 6. All disturbed soil areas not subject to revegetation shall be stabilized using approved chemical binders, jute netting, or other methods approved in advance by the SLOAPCD. 7. All roadways, driveways, sidewalks, etc. to be paved shall be completed as soon as possible. In addition, building pads shall be laid as soon as possible after grading unless seeding or soil binders or soil binders are used. 8. Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved surface at the construction site. 9. All trucks hauling dirt, sand, soil, or other loose materials are to be covered or shall maintain at least 2 feet of freeboard (minimum vertical distance between top of load and top of trailer) in accordance with California Vehicle Code Section 23114. 10. Install wheel washers where vehicles enter and exit unpaved roads onto streets or wash off trucks and equipment leaving the site. Sweep streets at the end of each day if visible soil material is carried onto adjacent paved roads. 11. Water sweepers shall be used with reclaimed water where feasible. Roads shall be pre-wetted prior to sweeping when feasible. 12. All PM10 mitigation measures required shall be shown on grading and building plans. 13. The contractor or builder shall designate a person or persons to monitor the fugitive dust emissions and enhance the implementation of the measures as necessary to minimize dust complaints, reduce visible emissions below the SLOAPCD limit of 20% opacity for no greater than 3 minutes in any 60-minute period. Their duties shall include holidays and weekend periods when work may not be in progress. The name and telephone number of such persons shall be provided to the SLOAPCD Compliance Division prior to the start of any grading, earthwork, or demolition. 13.14. All off-road construction equipment shall be Tier 3 or higher. AQ-3 Prior to initiation of demolition/construction activities, the applicant shall retain a registered geologist to conduct a geologic evaluation of the property including sampling and testing for naturally occurring asbestos in full compliance with California Air Resources Board (CARB) Air Toxics Control Measure (ATCM) for Construction, Grading, Quarrying, and Surface Mining Operations (CARB ATCM Section 93105) and SLOAPCD requirements. This geologic evaluation shall be submitted to the City Community Development Department upon completion. If the geologic evaluation determines that the project would not have the potential to disturb naturally occurring asbestos (NOA), the applicant must file an Asbestos ATCM exemption request with the San Luis Obispo County Air Pollution Control District (SLOAPCD). AQ-4 If naturally occurring asbestos (NOA) are determined to be present on-site, proposed earthwork and construction activities shall be conducted in full compliance with the various regulatory jurisdictions regarding NOA, including the California Air Resources Board (CARB) Asbestos Air Toxics Control Measure (ATCM) for Construction, Grading, Quarrying, and Surface Mining Operations (CARB ATCM Section 93105) and requirements stipulated in the National Emission Standards for Hazardous Air Pollutants (40 Code of Federal Regulations 61, Subpart M – Asbestos; NESHAP). These requirements include, but are not limited to, the following: Page 583 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 30 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 1. Written notification, within at least 10 business days of activities commencing, to the San Luis Obispo County Air Pollution Control District (SLOAPCD); 2. Preparation of an asbestos survey conducted by a Certified Asbestos Consultant; and, 3. Implementation of applicable removal and disposal protocol and requirements for identified NOA. AQ-5 Asbestos Material in Demolition. Demolition activities can have potential negative air quality impacts, including issues surrounding proper handling, demolition, and disposal of asbestos-containing material (ACM). ACMs could be encountered during demolition or remodeling of existing buildings. Asbestos can also be found in utility pipes/pipelines (transite pipes or insulation on pipes). If utility pipelines are scheduled for removal or relocation or a building(s) is proposed to be removed or renovated, various regulatory requirements may apply, including the requirements stipulated in the National Emission Standard for Hazardous Air Pollutants (40 Code of Federal Regulations [CFR] 61, Subpart M - asbestos NESHAP). These requirements include but are not limited to: (1) notification to the APCD; (2) an asbestos survey conducted by a Certified Asbestos Inspector; and (3) applicable removal and disposal requirements of identified ACM. More information on asbestos can be found at http://www.slocleanair.org/business/asbestos.php. Conclusion Standard mitigation measures have been identified above to address potential project impacts associated with sensitive receptors’ exposure to air pollutants and potential impacts associated with NOA and materials containing asbestos. Upon implementation of these measures, residual impacts associated with air quality would be less than significant. 4. BIOLOGICAL RESOURCES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? 1, 55, 56 ☐ ☒ ☐ ☐ b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? 1, 55, 56 ☐ ☒ ☐ ☐ c) Have a substantial adverse effect on state or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? 17, 55, 56 ☐ ☒ ☐ ☐ d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? 55, 56 ☐ ☒ ☐ ☐ e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? 3, 16 ☐ ☐ ☒ ☐ f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? 3 ☐ ☐ ☐ ☒ Page 584 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 31 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Evaluation This evaluation is based, in part, on the Biological Constraints Memorandum for a Proposed Project at 950 and 990 Aero Drive, San Luis Obispo, California, prepared by Terra Verde Environmental Consulting (Terra Verde) in February 2020 (included as Attachment 3), and the Waters and Wetland Delineation Report for Aero Drive Hotel Project at 950 and 990 Aero Drive, San Luis Obispo, California, prepared by Terra Verde in February 2020 (included as Attachment 4). The city is generally surrounded by open space, rangeland used for grazing, and other agricultural uses that support a variety of natural habitats and plant communities. The city’s many creeks provide sheltered corridors that allow local wildlife to move between habitats and open space areas. The City’s COSE identifies various goals and policies to maintain, enhance, and protect natural communities within the City’s planning area. These policies include, but are not limited to, protection of listed species and species of special concern, preservation of existing wildlife corridors, protection of significant trees, and maintaining development setbacks from creeks. The project site is in a developing portion of the city within the AASP area and is surrounded by commercial office and building uses, roadways, and is located directly northwest of the San Luis Obispo County Regional Airport. The project site currently consists of one unimproved, unoccupied parcel and a second parcel previously used as a parking lot that are proposed to be merged as part of the proposed project. The project area is dominated by ruderal herbaceous vegetation and non-native trees in the western portion of the area. The project site has been previously disturbed and considerably altered through past land conversion. The project area is characterized by flat to gently sloping land with a steep slope located at the southwest edge of the parcel. There is an unnamed drainage and associated wetland bordering the site that extends northwest across the southwestern portion of the project area. The project site is regularly mowed to control the growth of vegetation for fire control, as required by the City. a, b) Although unimproved, the project site is located in the developing AASP area and is largely surrounded by commercial office uses. The topography, soils, and vegetation of the project site and surrounding areas have been altered considerably through past maintenance activities, land conversion, and construction of adjacent commercial developments. The site has been regularly mowed since the early 2000s for fire control, as required by the City. The results of a literature review and observed site conditions indicate that three special-status plant species, two special-status animal species, and migratory nesting birds and raptors have the potential to occur on the project site or within the project vicinity. In addition to these species, jurisdictional aquatic habitat was observed within the southwestern portion of the survey area with marginally suitable habitat for vernal pool fairy shrimp (VPFS) (Branchinecta lynchi) and California red-legged frog (CRLF) (Rana draytonii). No special-status species were observed during field surveys conducted in November 2019, which is outside of the appropriate blooming period for most special-status plant species. Special-Status Plant Species Due to the high degree of land manipulation (e.g., placed fill, regular mowing etc.) within the project site, the habitat present is only marginally suitable for supporting special-status plant species. Low-suitability habitat is present within the project site for the following species: • Congdon’s tarplant (Centromadia parryi subsp. congdonii), California Rare Plant Rank (CRPR) 1B.1; • Hoover’s button-celery (Eryngium aristulatum var. hooveri), CRPR 1B.1; and • Adobe sanicle (Sanicula maritima), State Rare / CRPR 1B.1. No special-status plant species were observed during the survey. Low-suitability habitat is present within the drainage and associated wetland habitat on-site for Congdon’s tarplant, Hoover’s button-celery, and adobe sanicle. If present, Congdon’s tarplant would have been detectable at the time of surveys completed for the project site; therefore, the species is not expected to occur on-site. Though considered unlikely due to degraded site conditions, Hoover’s button-celery and adobe sanicle may be present within the ephemeral drainage and associated wetland habitat located in the southwestern portion of the project site. Presence of these species would not have been observed during the field survey conducted in November 2019. As shown on Figure 3, the project would avoid impacts to the ephemeral drainage and associated wetland habitat present within the project site through project design and the identified setback of 35 feet from State jurisdictional features. Implementation of Mitigation Measure BIO-2 would further ensure direct and indirect impacts to hydrological resources and habitat suitable for special-status plant species are avoided by requiring mapping and delineation of work areas and implementation of Best Management Practices (BMPs). Page 585 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 32 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Special-Status Animal Species The potential for any special-status animal species is considered low due to the disturbed nature of existing habitat within the project area, annual disturbance associated with ongoing site maintenance, and the lack of continuity with areas of adjacent suitable habitat. Special-status animal species determined to have low potential to occur on site include: • Vernal pool fairy shrimp (Branchinecta lynchi), Federal Threatened; and • California red-legged frog (Rana draytonii), Federal Threatened, State Species of Special Concern (SSC). No special-status animal species were documented during the survey conducted in November 2019. Very low-suitability habitat is present within the ephemeral drainage for VPFS and CRLF. CRLF may temporarily occupy the drainage when water is present; however, the drainage does not provide suitable breeding habitat due to its flashy and ephemeral flows and its lack of protective cover, nor does it maintain natural connection to downstream aquatic features such as the East Fork of San Luis Obispo Creek. The nearest documented occurrence of CRLF is from 2006, approximately 2 miles from the project site. In addition to the surveys completed by Terra Verde in 2019, wet and dry season protocol surveys were conducted for VPFS by David Wolff Environmental (DWE) in 2007 (DWE 2008b). No VPFS were observed during the protocol wet season surveys. Two intact cysts and one broken cyst identified to the genus Branchinecta were documented by Dr. Marie A. Simovich in the soil samples collected for the protocol dry season surveys. It was Dr. Simovich’s opinion that habitat with viable populations of fairy shrimp contain cysts in much higher densities than that found in the samples from this drainage (DWE 2008b). In addition, the hydroperiod for ponded water within the drainage, based on current site conditions, is not expected to support a breeding population of VPFS. Based on the results of the 2007 protocol-level survey coupled with the 2019 assessment of current site conditions, the likelihood of VPFS occurrence on-site is considered low. The project does not propose work within the ephemeral drainage located in the southwestern portion of the project area and CRLF and VPFS are not expected to be present at the project site based on a field survey and desktop review conducted in November 2019. However, Mitigation Measure BIO-1 is included in the event that a special-status species is observed during project construction. Suitable habitat for nesting birds and raptors is present within the project area, particularly in the ornamental trees along the northwest corner of the project site. Potential impacts to nesting birds and raptors are considered low because the project site is an infill site located near the airport and experiences a regular level of disturbance from vegetation maintenance and other surrounding land uses. A minimal amount of foraging habitat would be lost as a result of development. Avian species that may occur in or near the project site could be directly impacted if initial clearing, grubbing, grading, and/or construction activities occur during the typical avian nesting season (February 1–September 15), risking the possibility of nest failure. Indirect impacts could include disturbance associated with noise and dust during nesting activities. Mitigation Measure BIO-3 has been included to ensure potential impacts would be avoided and/or minimized to a less-than-significant level. Therefore, impacts would be less than significant with mitigation. c) There are no mapped blue line creeks within or immediately adjacent to the proposed area of disturbance. A portion of an unnamed ephemeral drainage extends along the southwestern property boundary. The drainage conveys water from the adjacent parking lot south of Aero Drive across the western portion of the project site before entering a 36-inch culvert in the northwest corner of the project site. The drainage is ephemeral, conveying surface flows from the project site and adjacent developments during periods of significant rainfall. To confirm the presence of wetlands along the ephemeral drainage, a wetland delineation was completed by Terra Verde in October 2019. Prior to the field delineation, a desktop review was conducted for the project site which included a review of current and historical aerial imagery, the Natural Resources Conservation Service (NRCS) Web Soil Survey of San Luis Obispo County, U.S. Geological Survey (USGS) topographic maps, regional weather data, the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI), and preliminary site development pans. Within the project area, the drainage displayed intermittent evidence of ordinary high-water mark (OHWM) and a clearly defined bed and bank. Portions of the drainage are likely considered non-wetland waters of the United States, based on the presence of a clearly defined OHWM identified by a distinct transition in vegetative cover, debris wracking, scour, and connectivity to traditionally navigable waters (the East Fork of San Luis Obispo Creek). Areas displaying evidence of OHWM are limited to two sections of the channel: (1) immediately downstream of the culvert under Aero Drive, and (2) in the section downstream of SP-04 until the central wetland (see Figures 3 and 5 in Attachment 4). These areas are connected by areas of federal-defined wetlands and also some transitional Page 586 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 33 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 areas where seasonal flows become less concentrated, fanning out into a wide floodplains and in-channel wetlands. These transitional areas did not display evidence of OHWM. The jurisdictional waters identified within the survey area fall under the regulatory jurisdiction of the U.S. Army Corps of Engineers (USACE), California Department of Fish and Wildlife (CDFW), and Regional Water Quality Control Board (RWQCB), as shown in Table 4. Table 4. Extent and Location of Jurisdictional Waters and Wetlands Feature Type Jurisdiction Acres Linear Feet Waters of the United States USACE 0.009 206 Waters/Wetlands of the State CDFW, RWQCB 0.63 650 Federal Wetlands USACE 0.13 N/A The project proposes to create a minimum 35-foot setback from the ephemeral drainage and associated wetland habitat located in the southwestern portion of the project area. The project proposes the construction of a retaining wall to separate the proposed parking lot from the wetland area during project operation. The project is not expected to directly affect any jurisdictional wetlands; however, Mitigation Measure BIO-2 has been identified to mitigate potential construction-related impacts to jurisdictional wetlands. Therefore, project impacts related to jurisdictional wetlands would be less than significant with mitigation. d) The project is not located within an area designated as a wildlife corridor within the COSE. In general, the project site does not contain habitat features conducive to migratory wildlife species; however, an ephemeral drainage corridor and connectivity with adjacent undeveloped areas may offer limited wildlife movement, particularly when the ephemeral drainage is flowing. Suitable habitat for nesting birds and raptors is present within the project area, particularly in the ornamental trees along the northwest corner of the project site. Potential impacts to nesting birds and raptors are considered low because the project site is an infill site located near the airport and experiences a regular level of disturbance from vegetation maintenance and other surrounding land uses. A minimal amount of foraging habitat would be lost as a result of development. Avian species that may occur in or near the project site could be directly impacted if initial clearing, grubbing, grading, and/or construction activities occur during the typical avian nesting season (February 1–September 15), risking the possibility of nest failure. Indirect impacts could include disturbance associated with noise and dust during nesting activities. Mitigation Measure BIO-2 has been included to ensure potential impacts to the ephemeral drainage and ornamental trees would be avoided and/or minimized to a less-than-significant level. Therefore, impacts would be less than significant with mitigation. e) The project site does not contain any heritage trees or significant native vegetation. The project site has been regularly mowed for fire control, as required by the City, preventing the growth of protected tree species. The existing mature ornamental trees along the northwestern property boundary would be protected by the proposed 35-foot setback for the wetland habitat and the project would be required to comply with the City’s Tree Ordinance (Chapter 12.24 of the City’s Municipal Code). Additional coast live oak (Quercus agrifolia), California pepper (Schinus mole), and other ornamental trees would be planted throughout the project site as landscaping. Therefore, the project would not adversely affect any heritage trees designated by the Heritage Tree Program or other protected trees. The COSE includes various goals and policies to maintain, enhance, and protect natural communities within the City’s planning area. These policies include, but are not limited to, protecting listed species and SSC, preserving existing wildlife corridors, protection of significant trees, and maintaining development setbacks from creeks. The project site provides marginal habitat for special-status species and potential impacts to these species would be mitigated with standard avoidance measures. The project site does not provide significant value as a wildlife corridor and does not contain significant mature or native trees. Per the site plans for the proposed project (refer to Attachment 1), the project design includes setback a minimum of 35 feet to avoid impacts to the ephemeral drainage and associated wetland habitat. The project would not result in a conflict with local policies or ordinances protecting biological resources and impacts; therefore, the potential impacts associated with conflicts with local policies would be less than significant. Page 587 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 34 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 f) The project is not located within an area under an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan. Therefore, the project would not conflict with the provisions of an adopted plan and no impacts would occur. Mitigation Measures BIO-1 The following measures shall be implemented prior to and during construction to avoid potential direct mortality and loss of California red-legged frogs: 1. Prior to the initial site investigation and subsequent ground-disturbing activities, a qualified biologist will instruct all project personnel in worker awareness training, including recognition of California red-legged frogs and their habitat. 2. A qualified biologist will conduct preconstruction surveys within the project area no earlier than 2 days before ground-disturbing activities. 3. No activities shall occur after October 15 or the onset of the rainy season, whichever occurs first, until May 1, except for during periods greater than 72 hours without precipitation. Activities can only resume after site inspection by a qualified biologist. The rainy season is defined as a frontal system that results in depositing 0.25 inches or more of precipitation in one event. 4. Vehicles to and from the project site will be confined to existing roadways to minimize disturbance of habitat. 5. Prior to movement of a backhoe in the project area, a qualified biologist will make sure the route is clear of California red-legged frogs. 6. If a California red-legged frog is encountered during excavations, or any project activities, activities will cease until the frog is removed and relocated by a U.S. Fish and Wildlife Service-approved biologist. Any incidental take will be reported to the USFWS immediately by telephone at (916) 414-6600. BIO-2 The following measures shall be implemented prior to and during construction to avoid impacts to hydrological resources located within and in the vicinity of the project site: 1. The limits of all work areas shall be clearly delineated in the field during construction and personnel shall be informed of the need to avoid impacts to jurisdictional aquatic features (i.e., waters and wetlands). 2. For short-term, temporary stabilization, an erosion and sedimentation control plan shall be developed outlining Best Management Practices (BMPs) and implemented to prevent erosion and sedimentation into the channel during construction. Acceptable stabilization methods include the use of weed-free, natural fiber (i.e., non- monofilament) fiber rolls, jute or coir netting, and/or other industry standards. BMPs shall be installed and maintained for the duration of the construction period. 3. The mapped limits of jurisdictional areas shall be clearly shown on all site plans and flagged prior to the start of any construction activity within 50 feet of the limits of the drainage. 4. All equipment and materials shall be stored a minimum of 35 feet from the edge of the drainage at the end of each working day, and secondary containment shall be used to prevent leaks and spills of potential contaminants from entering the drainage. 5. During construction, washing of concrete, paint, or equipment and refueling and maintenance of equipment shall occur only in designated areas a minimum of 35 feet from all drainages and aquatic features. Sandbags and/or sorbent pads shall be available to prevent any fluid releases from entering the drainage. 6. Construction equipment shall be inspected by the operator on a daily basis to ensure that equipment is in good working order and no fuel or lubricant leaks are present. 7. Where feasible, the project shall incorporate low impact development (LID) features, including bioswales and permeable pavers, into the overall site design to retain runoff on site and avoid increased surface runoff into the drainage. 8. Where feasible, the project shall incorporate vegetated buffers, bioswales, and/or rain gardens on the drainage side of the development. 9. The use of landscaping plants that are known or have potential to become invasive shall be prohibited. BIO-3 If any ground disturbance will occur during the nesting bird season (February 1–September 15), prior to any ground- disturbing activity, a preconstruction nesting bird survey shall be conducted by a qualified biologist within 1 week prior Page 588 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 35 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 to the start of activities. If nesting birds are located on or near the project site, they shall be avoided until they have successfully fledged, or the nest is no longer deemed active. A non-disturbance buffer of 50 feet will be implemented for non-listed, passerine species and a 250-foot buffer will be implemented for raptor species. No construction activities will be permitted within established nesting bird buffers until a qualified biologist has determined that the young have fledged or that proposed construction activities would not cause adverse impacts to the nest, adults, eggs, or young. If special-status avian species are identified, no work shall be conducted until an appropriate buffer is determined in consultation with the City and the California Department of Fish and Wildlife and/or U.S. Fish and Wildlife Service. Conclusion The project site supports marginal habitat for special-status plant and animal species, including Congdon’s tarplant, Hoover’s button celery, adobe sanicle, VPFS, CRLF, and nesting migratory birds. Potential impacts would be avoided through project design and mitigated through standard avoidance measures, BMPs, and regulatory permit requirements. The project would be setback at least 35 feet from the jurisdictional wetland areas and would not conflict with local plans or policies for protection of biological resources. Therefore, potential impacts to biological resources would be less than significant with mitigation. 5. CULTURAL RESOURCES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Cause a substantial adverse change in the significance of a historic resource pursuant to §15064.5? 3, 6, 18, 19, 58 ☐ ☐ ☒ ☐ b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? 3, 18, 19, 58 ☐ ☒ ☐ ☐ c) Disturb any human remains, including those interred outside of formal cemeteries? 3, 18, 19, 58 ☐ ☒ ☐ ☐ Evaluation This evaluation is based, in part, on the technical study An Archaeological Survey for the Airport Hotel Project, 950 & 990 Aero Drive, San Luis Obispo, San Luis Obispo County, California, prepared by Thor Conway of Heritage Discoveries Inc. in March 2007 (included as Attachment 5). Pre-Historic Setting Archaeological evidence demonstrates that Native American groups (including the Chumash) have occupied the Central Coast for at least 10,000 years. The city of San Luis Obispo is located within the area historically occupied by the Obispeño Chumash, the northernmost of the Chumash people of California. The Obispeño Chumash occupied much of San Luis Obispo County, and the earliest evidence of human occupation in the region comes from archaeological sites along the coast. The project site is not located within a Burial Sensitivity Area as identified in Figure 1: Cultural Resources of the City’s COSE. Historic Setting The City’s COSE establishes various goals and policies to balance cultural and historical resource preservation with other community goals. These policies include, but are not limited to the following: a) Identification, preservation, and rehabilitation of significant historic and architectural resources; b) Prevention of demolition of historically or architecturally significant buildings unless doing so is necessary to remove a threat to health and safety; c) Consistency in the design of new buildings in historical districts to reflect the form, spacing, and materials of nearby historic structures; and Page 589 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 36 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 d) Identification and protection of neighborhoods or districts having historical character due to the collective effect of Contributing or Master List historic properties. The project site is not located within the Historic Preservation (H) Overlay Zone, nor does it contain any built structures that may be considered potentially eligible historic resources. a) Neither the project site nor immediate vicinity contain buildings or structures that are old enough to qualify as potentially eligible historic resources. The project site and immediate vicinity primarily consist of recent development that has occurred subsequent to the 1980s. Therefore, the project would not result in a substantial adverse change in the significance of a historic resource pursuant to Section 15064.5 and potential impacts would be less than significant. b) The Archaeological Evaluation did not identify any previously known archeological sites in the project area, and a field survey of the project site revealed no evidence that further archaeological study is necessary for the project area. The project would include ground disturbance (approximately 10,000 cy of cut and 8,900 cy of fill) on-site associated with site preparation (i.e., grading), the installation of utilities and culverts, and the construction of the proposed hotel and parking lot, for a total net of 18,900 cy of proposed earthwork. The project proposes to disturb approximately 4.33 acres of land. The project site is not located within a Burial Sensitivity Area identified in Figure 1 of the City’s COSE; however, there is a potential to disturb previously unidentified buried cultural materials during subsurface grading and excavation activities. Mitigation Measure CR-1 has been identified to require cultural resource awareness training for all construction personnel. If previously unidentified cultural materials are unearthed during proposed ground-disturbing activities, Mitigation Measure CR-2 has been identified to require work be halted in the area until a City-qualified archaeologist can assess the significance of the find. With implementation of identified measures, impacts related to a substantial adverse change in the significance of archaeological resources would be less than significant with mitigation. c) The project site is not located within a Burial Sensitivity Area identified in Figure 1 of the City’s COSE. No human remains are known to exist within the project site; however, the discovery of unknown human remains is possible during ground- disturbing activities. Protocol for properly responding to the inadvertent discovery of human remains is identified in the California Health and Safety Code Section 7050.5 and would be required to be printed on all building and grading plans per Mitigation Measure CR-3. Potential impacts related to disturbance of human remains would be less than significant with incorporation of Mitigation Measure CR-3. Therefore, impacts related to disturbance of human remains would be less than significant with mitigation. Mitigation Measures CR-1 Prior to construction activities, a City-qualified archaeologist shall conduct cultural resource awareness training for all construction personnel including the following: 1. Review the types of archaeological artifacts that may be uncovered; 2. Provide examples of common archaeological artifacts to examine; 3. Review what makes an archaeological resource significant to archaeologists and local Native Americans; 4. Describe procedures for notifying involved or interested parties in case of a new discovery; 5. Describe reporting requirements and responsibilities of construction personnel; 6. Review procedures that shall be used to record, evaluate, and mitigate new discoveries; and 7. Describe procedures that would be followed in the case of discovery of disturbed as well as intact human burials and burial-associated artifacts. CR-2 If cultural resources are encountered during subsurface earthwork activities, all ground-disturbing activities within a 25-foot radius of the find shall cease and the City shall be notified immediately. Work shall not continue until a City- qualified archaeologist assesses the find and determines the need for further study. If the find includes Native American- affiliated materials, a local Native American tribal representative will be contacted to work in conjunction with the City- approved archaeologist to determine the need for further study. A standard inadvertent discovery clause shall be included in every grading and construction contract to inform contractors of this requirement. Any previously unidentified resources found during construction shall be recorded on appropriate California Department of Parks and Page 590 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 37 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Recreation (DPR) forms and evaluated for significance in terms of California Environmental Quality Act (CEQA) criteria by a qualified archaeologist. If the resource is determined significant under CEQA, the qualified archaeologist shall prepare and implement a research design and archaeological data recovery plan, in conjunction with locally affiliated Native American representative(s) as necessary, that will capture those categories of data for which the site is significant. The archaeologist shall also perform appropriate technical analysis, prepare a comprehensive report, and file it with the Central Coast Information Center (CCIC), located at the University of California, Santa Barbara, and provide for the permanent curation of the recovered materials. CR-3 In the event that human remains are exposed during earth disturbing activities associated with the project, an immediate halt work order shall be issued, and the City Community Development Director and locally affiliated Native American representative(s) (as necessary) shall be notified. California Health and Safety Code Section 7050.5 requires that no further disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains shall occur until the County Coroner has made the necessary findings as to origin and disposition pursuant to Public Resources Code (PRC) Section 5097.98. If the remains are determined to be of Native American descent, the coroner shall notify the Native American Heritage Commission within 24 hours. These requirements shall be printed on all building and grading plans. Conclusion With implementation of the recommended Mitigation Measures CR-1 through CR-3, the project would have a less-than- significant impact on cultural resources. 6. ENERGY Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? 1, 18, 20, 22 ☐ ☐ ☒ ☐ b) Conflict with or obstruct a state or local plan for renewable energy or energy efficiency? 1, 18, 20, 22 ☐ ☐ ☒ ☐ Evaluation Pacific Gas & Electric Company (PG&E) has historically been the primary electricity provider for the City. In October 2018, the City Council committed to joining Central Coast Community Energy (3CE, formerly Monterey Bay Community Power) and, beginning in January 2020, 3CE became the City’s primary electricity provider. 3CE is striving to provide 100% carbon-free electricity to the city by 2030. The California Building Code (CBC) contains standards that regulate the method of use, properties, performance, or types of materials used in the construction, alteration, improvement, repair, or rehabilitation of a building or other improvement to real property. The CBC includes mandatory green building standards for residential and nonresidential structures, the most recent version of which are referred to as the 2019 Building Energy Efficiency Standards. These standards focus on four key areas: smart residential photovoltaic systems, updated thermal envelope standards (preventing heat transfer from the interior to the exterior and vice versa), residential and nonresidential ventilation requirements, and non-residential lighting requirements. The City recently developed local amendments to encourage all-electric new buildings. When paired with 3CE’s carbon-free electricity supply, all electric new buildings will be carbon free and would avoid health and safety issues associated with fossil fuels and greenhouse gases (GHGs). At its meeting on September 3, 2019, the City Council adopted the Clean Energy Choice Program. Unlike other cities that are banning natural gas entirely, the proposed Clean Energy Choice Program encourages clean, efficient, and cost-effective all-electric new buildings through incentives, local amendments to the California Energy Code, and implementation of the Carbon Offset Program. New projects wishing to use natural gas will be required to build more efficient Page 591 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 38 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 and higher performing buildings and offset natural gas use by performing retrofits on existing buildings or by paying an in-lieu fee that will be used for the same purpose. Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building certification system that provides third-party verification that a building or community was designed and built using strategies aimed at improving performance metrics in energy savings, water efficiency, carbon dioxide (CO2) emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts. LEED provides a point system to score green building design and construction. The system is categorized in nine basic areas: Integrative Process, Location and Transportation, Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, Innovation in Design, and Regional Priority. Buildings are awarded points based on the extent various sustainable strategies are achieved. The more points awarded the higher the level of certification achieved from Certified, Silver, Gold, to Platinum. The City’s COSE establishes goals and policies to achieve energy conservation and increase use of cleaner, renewable, and locally controlled energy sources. These goals include increasing the use of sustainable energy sources and reducing reliance on non-sustainable energy sources to the extent possible and encouraging the provision for and protection of solar access. Policies identified to achieve these goals include, but are not limited to, use of best available practices in energy conservation, procurement, use, and production; energy-efficiency improvements; pedestrian- and bicycle-friendly facility design; fostering alternative transportation modes; compact, high-density housing; and solar access standards. The City of San Luis Obispo Climate Action Plan for Community Recovery (2020 CAP) also identifies strategies and policies to increase use of cleaner and renewable energy resources in order to achieve the City’s GHG emissions reduction target. These strategies include promoting a wide range of renewable energy financing options, incentivizing renewable energy generation in new and existing developments, and increasing community awareness of renewable energy programs. The City’s 2020 CAP was updated in August 2020. a) During construction, fossil fuels, electricity, and natural gas would be used by construction vehicles and equipment. The energy consumed during construction would be temporary in nature and would be typical of other similar construction activities in the city. State and federal regulations in place require fuel-efficient equipment and vehicles and prohibit wasteful activities, such as diesel idling; therefore, potential impacts associated with construction energy use would be less than significant. Operation of the project would result in an overall increase in consumption of energy resources associated with vehicle trips, electricity, and natural gas usage by project occupants. The project would rely on the local electricity service provider 3CE to supply project electricity needs. 3CE is striving to provide 100% carbon-free electricity to the city by 2030. The project would be designed in full compliance with the CBC, including applicable green building standards, which include thermal envelope standards (preventing heat transfer from the interior to the exterior and vice versa), nonresidential ventilation requirements, and nonresidential lighting requirements. Based on the LEED checklist provided by the applicant, the project would be built to a certified level (included as Attachment 6). Compliance with existing building codes would ensure the project would not result in a potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, and through use of 100% GHG-free electricity resources, project energy use would not result in a significant environmental impact; therefore, impacts would be less than significant. b) The project would be designed in full compliance with the CBC including applicable green building standards. The project would be consistent with energy goals and policies in the COSE associated with use of best available practices in energy conservation, encouraging energy-efficient building design and the use of pedestrian- and bicycle-friendly design. The project would not conflict with other goals and policies set forth in the City’s 2020 CAP associated with renewable energy or energy efficiency. Therefore, the project would not result in a conflict with or obstruction of a state or local plan for renewable energy or energy efficiency, and impacts would be less than significant. Mitigation Measures Mitigation measures are not required. Page 592 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 39 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Conclusion The project has been located and designed in full compliance with applicable energy efficiency standards and would not conflict with state or local plans for renewable energy or energy efficiency. No potentially significant impacts related to energy would occur and mitigation measures are not required. 7. GEOLOGY AND SOILS Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving: i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. 23, 24, 25, 26, 27 ☐ ☐ ☒ ☐ ii. Strong seismic ground shaking? 23, 24 ☐ ☐ ☒ ☐ iii. Seismic-related ground failure, including liquefaction? 24, 25 ☐ ☐ ☒ ☐ iv. Landslides? 26, 27 ☐ ☐ ☒ ☐ b) Result in substantial soil erosion or the loss of topsoil? 24 ☐ ☒ ☐ ☐ c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? 24, 25 ☐ ☐ ☒ ☐ d) Be located on expansive soil, as defined in Table 1802.3.2 of the California Building Code (2013), creating substantial direct or indirect risks to life or property? 24, 27 ☐ ☐ ☒ ☐ e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? 1 ☐ ☐ ☐ ☒ f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? 28 ☐ ☐ ☒ ☐ Evaluation The City’s Safety Element identifies active, potentially active, and inactive mapped and inferred faults with the potential to affect the city in the event of rupture. The Los Osos Fault, adjacent to the city of San Luis Obispo, is identified under the State of California Alquist-Priolo Fault Hazards Act and is classified as active. The West Huasna, Oceanic, and Edna Faults are considered potentially active and present a moderate fault rupture hazard to developments near them. The San Andreas Fault and offshore Hosgri Fault, which present the most likely source of ground shaking for San Luis Obispo, have a high probability of producing a major earthquake within an average lifespan. The highest risk from ground shaking is found on deep soils that were deposited by water, are geologically recent, and have many pore spaces among the soil grains. These soils are typically found in valleys. Faults capable of producing strong ground-shaking motion in San Luis Obispo include the Los Osos, Point San Luis, Black Mountain, Rinconada, Wilmar, Pecho, Hosgri, La Panza, and San Andreas Faults. Engineering standards and building codes set minimum design and construction methods for structures to resist seismic shaking. Based on the DOC Fault Activity Page 593 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 40 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Map and the City’s Safety Element Earthquake Faults – Local Area map, the project site is not located within or in the immediate vicinity of an active fault zone. Seismic-Related Ground Failure Settlement is defined as the condition in which a portion of the ground supporting part of a structure or facility lowers more than the rest or becomes softer, usually because ground shaking reduces the voids between soil particles, often with groundwater rising in the process. Liquefaction is the sudden loss of the soil’s supporting strength due to groundwater filling and lubricating the spaces between soil particles as a result of ground shaking. Soils with high risk for liquefaction are typically sandy and in creek floodplains or close to lakes. In extreme cases of liquefaction, structures can tilt, break apart, or sink into the ground. The likelihood of liquefaction increases with the strength and duration of an earthquake. Based on the Ground Shaking and Landslide Hazards Map in the City’s Safety Element, the project site is located within an area with high liquefaction potential. Slope Instability and Landsides Slope instability can occur as a gradual spreading of soil, a relatively sudden slippage, a rockfall, or in other forms. Causes include steep slopes, inherently weak soils, saturated soils, and earthquakes. Improper grading and manmade drainage can be contributing factors. Much of the development in San Luis Obispo is in valleys, where there is low potential for slope instability. Based on the Ground Shaking and Landslide Hazards Map in the City’s Safety Element, the project site is located within an area with moderate landslide potential. Subsidence Land subsidence is a gradual settling or sudden sinking of the Earth’s surface due to subsurface movement of earth materials. Primary causes are groundwater withdrawal, in which water is removed from pore space as the water table drops, causing the ground surface to settle; tectonic subsidence, where the ground surface is warped or dropped lower due to geologic factors such as faulting or folding; and earthquake-induced shaking that causes sediment liquefaction, which in turn can lead to ground- surface subsidence. Based on the USGS Areas of Land Subsidence in California Map, the project site is not located in an area of known subsidence. Soil Limiting Factors The project site is mostly underlain by the Salinas silty clay loam (0–2 percent slopes) soil unit. This very deep, well-drained, gently sloping soil has moderately slow permeability and slow surface runoff. The hazard of water erosion is slight. Many areas underlain by this soil are used for urban development; roads, buildings, and other structures need to be designed with consideration of the soil’s low strength and moderate shrink-swell potential. The project site is also underlain by the Cropley clay (2–9 percent slopes) soil unit. This soil unit is characterized by gentle slopes and medium runoff and is moderately drained. a.i) Based on Figure 3 (Earthquake Faults – Local Area) of the City’s Safety Element and the DOC Fault Activity Map of California, no known fault lines are mapped on or within 0.5 mile of the project site. Therefore, the project would not have the potential to result in substantial adverse effects involving rupture of a known earthquake fault and impacts would be less than significant. a.ii) Due to the highly seismic nature of the region, the project would very likely be subject to strong seismic ground shaking at some point(s) during the life of the project. The proposed development would be required to be designed in full compliance with seismic design criteria established in the CBC to adequately withstand and minimize the risk associated with the level of seismic ground shaking expected to occur in the project region; therefore, impacts associated with strong seismic ground shaking would be less than significant. a.iii) Based on the Ground Shaking and Landslide Hazards Map in the City’s Safety Element, the project site is located within an area with high liquefaction potential. Development of the project within this area may have the potential to result in adverse effects due to seismic-related ground failure. A soils report prepared by a qualified engineer is required upon review of the building permit to address the nature of the subsurface soils in response to liquefaction potential, in accordance with CBC Chapter 18. Any issues identified in the report will be addressed through standard site construction techniques, as required by the CBC. This report would also ensure consistency with Policy 4.7 of the City’s Safety Element, which states proposed development may be located in high liquefaction potential areas only after completion of a site- specific investigation for risk of damage from liquefaction. In addition, the proposed development would be required to be designed in compliance with standard seismic design criteria established in the CBC to reduce risk associated with seismic-related ground failure, including liquefaction. Therefore, based on compliance with existing regulations, impacts related to substantial adverse effects due to seismic-related ground failure would be less than significant. Page 594 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 41 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 a.iv) Based on the Ground Shaking and Landslide Hazards Map in the City’s Safety Element, the project site is located within an area of moderate landslide potential. The project site and surrounding areas are predominantly flat, which further reduces the risk for a landslide to occur. In addition, the proposed development would be required to be designed in compliance with standard seismic design criteria established in the CBC to reduce risk associated with seismic-related ground failure; therefore, the project would not result in significant adverse effects associated with landslides, and impacts would be less than significant. b) The project would require approximately 10,000 cy of cut and 8,900 cy of fill for a net of 18,900 cy of earthwork and a total of 4.33 acres of ground disturbance. The project site is predominantly flat and no substantial vegetation removal or permanent changes in existing topography would occur. Grading permits are required for projects, excavations, or fills exceeding 50 cubic yards in volume and require implementation of standard BMPs to ensure substantial erosion, siltation, and/or sedimentation are avoided. The project is also required to comply with the Central Coast Regional Water Quality Control Board (RWQCB) requirements set forth in their Post-Construction Stormwater Management Requirements for Development Projects in the Central Coast region. Physical improvement of the project site will be required to comply with the drainage requirements of the City’s Waterway Management Plan. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. Based on the relatively short period of time that soils would be susceptible to erosion, and because construction activities would require implementation of erosion control and water quality measures as required by existing regulations and standard mitigation measures identified in BIO-2, impacts associated with erosion during construction would be reduced to less than significant with mitigation. Following project completion, the project site would be developed with buildings, hardscapes, and landscaping, precluding the potential for substantial long-term erosion or loss of topsoil. Therefore, impacts related to soil erosion and loss of topsoil would be less than significant with mitigation. c) Landslides typically occur in areas with steep slopes or in areas containing escarpments. Based on the Ground Shaking and Landslide Hazards Map in the City’s Safety Element, the project site is located within an area with moderate landslide potential; however, the project site is located on relatively flat land. Based on the City’s Safety Element and USGS data, the project site is not located in an area of historical or current land subsidence. Based on the Ground Shaking and Landslide Hazards Map in the City Safety Element, the project site is located within an area with high liquefaction potential. A soils report prepared by a qualified engineer is required upon review of the building permit to address the nature of the subsurface soils in response to liquefaction potential, in accordance with the CBC Chapter 18. Any issues identified in the report will be addressed through standard site construction techniques, as required by the CBC. The project would also be required to comply with CBC seismic requirements to address potential seismic-related ground failure, including lateral spread and liquefaction. Therefore, based on compliance with existing regulations, potential impacts related to location on a geologic unit or soil unit that is unstable would be less than significant. d) Based on the Soil Survey of San Luis Obispo County and Web Soil Survey, the project site is located in an area underlain by Salinas silty clay loam, 0 to 2 percent slopes, and Cropley clay, 2 to 9 percent slopes. Typically, soils that consist of clay or clay materials have a higher shrink-swell potential than soils without clay or clay materials. The soils at the site consist of clay materials and would be considered to have a moderate shrink-well potential. The volume changes that soils undergo in this cyclical pattern can stress and damage slabs and foundations. A soils report prepared by a qualified engineer is required, per the CBC and Policy 4.7 of the City’s Safety Element, upon review of the building permit to evaluate the proposed development activities and provide specific recommendations to adequately protect future proposed development against soil stability hazards, including expansive soils. Typical precautionary measures would likely include premoistening of the underlying soil in conjunction with placement of non-expansive material beneath slabs, and a deepened and more heavily reinforced foundation. Therefore, based on compliance with existing regulations, potential impacts associated with expansive soils would be less than significant. e) The proposed project includes a new connection to the City’s sewer system. No septic tanks or alternative wastewater treatment systems are proposed on-site; therefore, no impacts would occur. f) The project site is underlain by Holocene-age alluvial gravel and sand of stream channels. Holocene age units, particularly those younger than 5,000 years old, are generally too young to contain fossilized material. The project would result in approximately 18,900 total cy of earthwork; however, the hotel would be constructed on a concrete slab foundation and does not propose subterranean parking that would require cut activity within the bedrock. Therefore, potential impacts to paleontological resources would be less than significant. Page 595 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 42 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Mitigation Measures Implement Mitigation Measure BIO-2. Conclusion Based on the location of the project site and underlying geologic and soil properties, and compliance with existing regulations, potential impacts related to seismic and other ground failure and damage to paleontological resources would be less than significant. However, earthwork related to project construction has the potential to result in erosive runoff. In addition to compliance with existing regulations, implementation of Mitigation Measure BIO-2 would reduce impacts to less than significant. 8. GREENHOUSE GAS EMISSIONS Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? 2, 12, 21, 53 ☐ ☒ ☐ ☐ b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? 12, 20, 21, 53 ☐ ☒ ☐ ☐ Evaluation This evaluation is based, in part, on the Emissions Modelling Report for the San Luis Obispo Airport Hotels Project, prepared by AMBIENT Air Quality & Noise Consulting in January 2021 (included as Attachment 2). GHGs are any gases that absorb infrared radiation in the atmosphere, and are different from the criteria pollutants discussed in Section 3, Air Quality. The primary GHGs that are emitted into the atmosphere as a result of human activities are CO2, methane (CH4), nitrous oxide (N2O), and fluorinated gases. In 2012 the City established a Climate Action Plan that identified measures and implementation strategies in order to achieve the City’s GHG reduction target of 1990 emission levels by 2020. In 2020 the City prepared an updated Climate Action Plan for Community Recovery, which outlines a strategy for achieving carbon neutrality by 2035, adopts sector specific goals, and provides foundational actions to establish a trajectory towards achieving those goals. In 2018 the City prepared a community-wide inventory of GHG emissions for the 2016 calendar year. In 2016 San Luis Obispo’s total GHG emissions were estimated to be 339,290 metric tons of carbon dioxide equivalence (MTCO2e). As in 2005, transportation was the largest contributor to the City’s total GHG emissions with an estimated 212,980 MTCO2e or 63% of the City’s total emissions. Commercial and Industrial energy was the second largest sector with GHG emissions of 44,270 MTCO2e or 13% of the City’s total emissions. The sectors of residential energy and solid waste account for the remaining 26% of the City’s total 2016 GHG emissions. Due to lagging data availability, 2016 is the most recent year for complete GHG inventory data. Statewide legislation, rules, and regulations have been adopted to reduce GHG emissions from significant sources. Senate Bill (SB) 32 and Executive Order (EO) S-3-05 extended the State’s GHG reduction goals and required the CARB to regulate sources of GHGs to meet a state goal of reducing GHG emissions to 1990 levels by 2020, 40% below 1990 levels by 2030, and 80% below 1990 levels by 2050. Other statewide policies adopted to reduce GHG emissions include Assembly Bill (AB) 32, SB 375, SB 97, Clean Car Standards, Low Carbon Fuel Standard, Renewable Portfolio Standard, California Building Codes, and the California Solar Initiative. Appendix C of the 2020 CAP Update includes thresholds and guidance for the preparation of GHG emissions analysis under CEQA for projects within the city. To support progress toward the City’s long‐term aspirational carbon neutrality goal, plans and projects within the city that undergo CEQA review will need to demonstrate consistency with targets in the CAP, a Qualified GHG Emissions Reduction Plan, consistent with CEQA Guidelines Section 15183.5. According to the adopted SLOAPCD guidance, if a project is consistent with a qualified GHG reduction strategy, such as the City’s 2020 CAP, the project would not result in a significant impact. In October 2018, the City Council committed to joining C3E, an existing community choice energy program that serves the counties of Santa Cruz, San Benito, and Monterey and provides 100% carbon-free electricity with a rate savings relative to Page 596 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 43 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 PG&E. Additionally, the City recently adopted the Clean Energy Choice Program for New Buildings, which encourages clean, efficient, and cost-effective all-electric new buildings through incentives and local amendments to the California Energy Code. When paired with cost-comparable modern electric appliances and carbon-free electricity from C3E, all-electric new buildings are operationally GHG emissions-free, cost effective, and help achieve the community’s climate action goals. a) As discussed previously, the proposed project would be consistent with the City’s BP land use and zoning designation, pending approval of a Conditional Use Permit (CUP). As such, the project is expected to be consistent with the demographic and land use assumptions used for development of the City’s 2020 CAP. The project’s GHG emissions have been quantified using California Emissions Estimator Model (CalEEMod), version 2016.3.2, based on estimated acreage and building square footage provided for the proposed project. The buildout year for this project would be post year 2020. The GHG efficiency threshold was calculated by dividing the GHG emissions inventory goal (allowable emissions), by the estimated service population (SP). The efficiency threshold was calculated based on CARB’s GHG emissions inventory identified in the 2017 Scoping Plan Update. Project-generated GHG emissions that would exceed the efficiency threshold of 7.0 MTCO2e/SP/year would be considered to have a potentially significant impact on the environment that could conflict with GHG-reduction planning efforts. To be conservative, amortized construction-generated GHG emissions were included in annual operational GHG emissions estimates. The project’s short-term emissions were quantified using CalEEMod, version 2016.3.2, based on estimated acreage and building square footage provided for the proposed project. Based on the modeling conducted, construction-related GHG emissions would total approximately 592.28 MTCO2e. Amortized GHG emissions, when averaged over the assumed 25-year life of the project, would total approximately 23.69 MTCO2e/year. Long-term operational GHG emissions were calculated using CalEEMod, version 2016.3.2. Energy use included emissions associated with natural gas use. Electricity use assumes service would be supplied by 3CE, which provides renewable and carbon-free electricity, per the City’s existing commitment. Mobile-source emissions were based on vehicle trip generation rates for proposed residential land uses derived from the Transportation Impact Study prepared for the project (W-Trans 2020). Estimated long-term increases in GHG emissions associated with the proposed project for buildout year 2023 and future year 2030 are summarized in Table 5. Table 5. GHG Emissions Summary Source Total MTCO2e (Tons/Year) Construction Emissions Total Construction Emissions (2022-2023) 592.28 Amortized Construction Emissions (Over 25 Years) 23.69 Amortized Construction Emissions 23.7 Operational Emissions Annual Operational Emissions – Year 2023 without TDM 1,598.95 Annual Operational Emissions – Year 2023 with TDM 1,561.28 Annual Operational Emissions – Year 2030 without TDM 1,394.5 Annual Operational Emissions – Year 2030 with TDM 1,361.7 Total Operational Emissions with Amortized Construction Emissions without TDM 1,418.2 Total Operational Emissions with Amortized Construction Emissions and TDM 1,385.4 Service Population (Employees) 25 Page 597 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 44 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 MTCO2e / Service Population 55.4 2020 CAP Threshold (per employee) 0.7/employee (17.5) Reduction Required to Meet CAP Threshold (MTCO2e) 1,367.9 Reduction Required to Meet CAP Threshold (MTCO2e/Service Population) 54.7 As depicted in Table 5, operational GHG emissions for the proposed project, with the inclusion of amortized construction GHGs, would total approximately 1,385.4 MTCO2e (1,598.95 MTCO2e/year during the initial year of full operation [year 2023] and 1,418.2 MTCO2e/year for operational year 2030). Based on a service population of 25 employees, the project’s GHG emissions would exceed the GHG threshold of 0.7 MTCO2e per employee (17.5 MTCO2e based on a service population of 25) as established by the 2020 CAP. Therefore, the project would result in a potentially significant impact and would require a reduction of 1,367.9 MTCO2e to be below the City’s threshold. Mitigation Measures AQ-1 and AQ-2 have been included to require implementation of measures identified by the SLOAPCD to reduce emissions during project construction. Additionally, Mitigation Measure GHG-1 has been incorporated to increase use of alternative means of transportation, waste reduction, and the use of carbon-free energy through the discouraged installation of natural gas-fired appliances, as well as electricity service provided by 3CE. With implementation of Mitigation Measures AQ-1, AQ-2, and GHG-1, construction and operational GHG emissions would be reduced throughout the project’s lifetime to achieve a total reduction of 1,367.9 MTCO2e (or 54.7 MTCO2e per employee based on a service population of 25). Therefore, potential impacts associated with generation of GHG emissions that may have a significant impact on the environment would be less than significant with mitigation. b) The San Luis Obispo Council of Governments (SLOCOG) was assigned a GHG-reduction target of 11% from transportation sources by 2035. SLOCOG adopted the 2019 Regional Transportation Plan/Sustainable Community Strategies (RTP/SCS) in June 2019, which includes the region’s SCS and meets the requirements of SB 375. In September 2018, the City Council directed City staff to develop a climate action plan with a reduction target of carbon neutrality by 2035. A carbon neutrality by 2035 target would require achieving a far greater reduction than the SB 32 requirements by 2030, as identified in the State’s 2017 Scoping Plan. On July 20, 2020, SLOCOG issued a letter that determined the City’s 2020 CAP was consistent with the GHG reduction noted in the SCS for meeting the State’s 2030 GHG-reduction target. As a result, determination of consistency with the City’s 2020 CAP would ensure consistency with the GHG-reduction targets identified in the RTP/SCS. As discussed previously, tThe City’s recently adopted the 2020 CAP, which identifies six pillars, each of which include long-term goals, measures, and foundational actions for reducing GHG emissions throughout the city. The pillars include: 1. Leading by Example: Create a Municipal Action Plan by 2020 and achieve carbon neutral government operations by 2030. 2. Clean Energy Systems: Achieve 100% carbon-free electricity by 2020. 3. Green Buildings: Generate no net new building emissions from on‐site energy use by 2020 and achieve a 50% reduction in existing building on‐site emissions (after accounting for 3CE) by 2030. 4. Connected Community: Achieve the General Plan mode split objective by 2030 and have 40% vehicle miles traveled (VMT) by electric vehicles by 2030. 5. Circular Economy: Achieve 75% diversion of landfilled organic waste by 2025 and 90% by 2035. 6. Natural Solutions: Increase carbon sequestration on the San Luis Obispo Greenbelt and Urban Forest through compost application-based carbon farming activities and tree planting to be ongoing through 2035. Projects that are consistent with the demographic forecasts and land use assumptions used in the 2020 CAP can utilize the City’s CEQA GHG Emissions Analysis Compliance Checklist to demonstrate consistency with the 2020 CAP’s GHG emissions reduction strategy. The demographic forecasts and land use assumptions of the CAP are based on the City’s Land Use and Circulation Elements. If a plan or project is consistent with the existing 2014 General Plan land use and zoning designations of the project site, then the project would be considered consistent with the demographic forecasts and the land uses assumptions of the Climate Action Plan. The project is consistent with the City’s land use and zoning designation and would be consistent with the demographic and land use assumptions used for the development of the 2020 Page 598 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 45 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 CAP. The proposed project would not result in an increase in employment or population estimates that would conflict with those used for development of the City’s CAP or SLOCOG’s RTP/SCS. According to VMT analysis conducted by GHD for the proposed project, the project would result in a net increase of 393 VMT, constituting a 0.005% increase. This increase in traffic generated by the proposed project would exceed the City’s adopted VMT thresholds by the equivalent of approximately 48 daily auto trips, resulting in a significant impact. According to the Multimodal Transportation Impact Study prepared for the project (W-Trans 2020), the project is expected to generate an average of 1,822 daily trips. Based on an assessment of trip lengths from the project’s traffic analysis zone within the model, it is estimated the average project trip length is approximately 8.3 miles. Therefore, approximately 48 project trips are contributing to the net increase in regional VMT. The project will need to implement TDM measures to reduce VMT by 393 or approximately 48 daily trips (3% reduction). Mitigation Measures TR-1 and TR-2 have been included to ensure the project does not result in a net increase in regional VMT. As described in the Recommended Transportation Demand Measures document prepared for the proposed project, the TDM measures would result in a VMT reduction of 4.93%. Further, through compliance with City Zoning Regulations requiring provision of secure bicycle storage, showers, and locker and changing room facilities to encourage project employees to use alternative modes of transportation, as well as being within immediate proximity of the Class II bicycle lane on Broad Street, the project would promote alternate modes of travels that would further reduce VMT. The City has prepared a CEQA GHG Emissions Analysis Compliance Checklist for plans and projects to ensure that they are consistent with the pillars of the CAP. Based on the analysis provided in Table 6, the project would be consistent with the City’s GHG Emissions Analysis Checklist with implementation of Mitigation Measure GHG-1. Mitigation measures and offsets have been incorporated to ensure consistency with the City’s 2020 CAP, which (in total) would achieve project-level GHG reductions in excess of 90%. For these reasons, with mitigation, the proposed project would not be inconsistent with SLOCOG’s RTP/SCS or the State’s 2017 Scoping Plan. Therefore, potential impacts associated with a conflict with a plan or policy adopted for the purpose of reducing GHG emissions of would be less than significant with mitigation. Table 6. Project Consistency with the City’s Climate Action Plan Climate Action Plan Measures Project Consistency Clean Energy Systems Does the Project include an operational commitment to participate in Central Coast Community Energy? Consistent with Mitigation. A mitigation measure has been included to require an operational commitment to participate in 3CE. Green Buildings Does the Project exclusively include “All-electric buildings”? For the purpose of this checklist, the following definitions and exemptions apply: All-electric building. A new building that has no natural gas plumbing installed within the building and that uses electricity as the source of energy for all space heating, water heating, cooking appliances, and clothes drying appliances. An All-Electric Building may be plumbed for the use of natural gas as fuel for appliances in a commercial kitchen. Specific exemptions to the requirements for all - electric buildings include: Commercial kitchens a. The extension of natural gas infrastructure into an industrial building for the purpose of supporting manufacturing processes (i.e., not including space conditioning). Consistent. The project would include development of either all electric or mixed-fuel buildings and would be required to be in full compliance with the City’s Energy Reach Code. Additionally, the project proposes a commercial kitchen, which would likely use natural gas; however, this action has been accounted for in the 2020 CAP. Page 599 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 46 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 b. Accessory Dwelling Units that are attached to an existing single-family home. Essential Service Buildings including, but not limited to, public facilities, hospitals, medical centers and emergency operations centers. c. Temporary buildings. d. Gas line connections used exclusively for emergency generators. e. Any buildings or building components exempt from the California Energy Code. f. Residential subdivisions in process of permitting or constructing initial public improvements for any phase of a final map recorded prior to January 1, 2020, unless compliance is required by an existing Development Agreement. If the proposed project falls into an above exemption category, what measures are applicants taking to reduce onside fossil fuel consumption to the maximum extent feasible? If not applicable (N/A), explain why this action is not relevant. Connected Community Does the Project comply with requirements in the City’s Municipal Code with no exceptions, including bicycle parking, bikeway design, and EV charging stations? Consistent. The project has been designed to comply with the requirements in the City’s Municipal Code and would be required to demonstrate compliance with applicable Municipal Code requirements related to bicycle parking, bikeway design, and EV charging stations. The project includes 51 EV parking spaces, 22 bicycle parking spaces, and associated lockers and showers for employees. Is the estimated Project-generated Vehicle Miles Traveled (VMT) within the City’s adopted thresholds, as confirmed by the City’s Transportation Division? Consistent with Mitigation. Transportation Demand Management (TDM) recommendations have been included as Mitigation Measure TR-2. If “No,” does the Project/Plan include VMT mitigation strategies and/or a Transportation Demand Management (TDM) Plan approved by the City’s Transportation Division? Does the Project demonstrate consistency with the City’s Bicycle Transportation Plan? Consistent. The project has been designed to include, and would be required to incorporate, features to promote alternative means of transportation, including the installation of bicycle facilities connecting to off-site existing or planned bicycle facilities. Circular Economy Will the Project subscribe all units and/or buildings to organic waste pick up and provide the appropriate on-site enclosures consistent with the provisions of the City of San Luis Obispo Development Standards for Solid Waste Services? Please provide a letter from San Luis Garbage company verifying that the project complies with their Consistent with Mitigation. A mitigation measure has been included to require the project to provide organic waste pick up and provide the appropriate on-site enclosures consistent with the provisions of the City’s Development Standards for Solid Waste Services. Page 600 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 47 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 standards and requirements for organic waste pick up. Natural Solutions Does the Project comply with Municipal Code requirements for trees? Consistent. The project would require removal of four pepper trees and one acacia tree, which would require compensation per Section 12.24.090 (Tree Removal) of the City's Municipal Code. Mitigation Measures Implement Mitigation Measures AQ-1, and AQ-2, TR-1, and TR-2 in addition to the following measure. GHG-1 A Greenhouse Gas Reduction Plan (GGRP) shall be prepared for the proposed project and shall be submitted to the City for review and approval prior to issuance of grading or building permits. The GGRP shall require annual impacts to be quantified over the life of the project to also account for reduction in project impacts due to future emission reduction technology that is included in the California Emissions Estimator Model (CalEEMod) and shall reduce annual greenhouse gas (GHG) emissions from the development by a minimum of 1,367.9 metric tons of carbon dioxide equivalence (MTCO2e) per year over the operational life of the proposed project. GHG emissions may be reduced through the implementation of on-site mitigation measures, off-site mitigation measures, or through the purchase of carbon offsets. It is recommended that the GGRP incorporate GHG-reduction measures identified in the City of San Luis Obispo’s CEQA GHG Emissions Analysis Compliance Checklist, Climate Action Plan Consistency Checklist for New Development, as listed below. In the event that carbon offsets are required, carbon offsets shall be purchased from a validated/verifiable source, such as the California Climate Action Registry, and approved by City Planning staff prior to purchase. 1. The project shall be provided electricity by 3CE. 2. The project shall incorporate a pedestrian and bicycle access network that connects proposed on-site land uses to adjacent existing or planned pedestrian and bicycle facilities contiguous with the project site. 3. The project shall be designed to minimize barriers to pedestrian access and interconnectivity. 4. The project shall be designed to provide safe and convenient access to public transit contiguous to the project site. 5. Transportation Demand Management (TDM) reduction measures should be included to reduce vehicle miles traveled (VMT), which include but are not limited to: a. Telecommuting; b. Car sharing; c. Shuttle service; d. Carpools; e. Vanpools; f. Participation in the SLO Rideshare Back ‘N’ Forth Club; g. Transit subsidies; and h. Off-site sustainable transportation infrastructure improvements. 6. The project shall provide organic waste pick up and shall provide the appropriate on-site enclosures consistent with the provisions of the City’s Development Standards for Solid Waste Services. Conclusion The proposed project would generate GHG emissions during construction and operation in quantities that exceed the threshold established by the City’s 2020 CAP; therefore, the project would result in a potentially significant impact related to GHG emissions and consistency with the 2020 CAP. Mitigation has been included that would ensure GHG emissions would be reduced below the applicable threshold and ensure the project is consistent with the six pillars of the CAP; therefore, impacts would be less than significant with mitigation.

Various state and local government agencies are required to track and document hazardous material release information for the Cortese List. The California Department of Toxic Substance Control (DTSC) EnviroStor database tracks DTSC cleanup, permitting, enforcement, and investigation efforts at hazardous waste facilities and sites with known contamination, such as federal superfund sites, state response sites, voluntary cleanup sites, school cleanup sites, school investigation sites, and military evaluation sites. The State Water Resources Control Board (SWRCB) GeoTracker database contains records for sites that impact, or have the potential to impact, water in California, such as Leaking Underground Storage Tank (LUST) sites, Department of Defense sites, and Cleanup Program Sites. The remaining data regarding facilities or sites identified as meeting the “Cortese List” requirements can be located on the CalEPA website: https://calepa.ca.gov/sitecleanup/corteselist/. Based on a review of the SWRCB GeoTracker database and the DTSC EnviroStor database, the project site is not an active hazardous waste cleanup site. There is one inactive hazardous waste evaluation located within 1,000 feet of the project site at the San Luis Obispo County Regional Airport. The closest investigation site is located over 1,000 feet away, at 710 Aerovista Place, as discussed below. The project site is located within the San Luis Obispo County Regional Airport Land Use Planning Area and is within Airport Safety Zone S-1C. Based on previous coordination between the City and the DTSC, the San Luis Obispo County Regional Airport property is known to have been used by the U.S. Army Air Corps and the California National Guard as early as November 1938 and continued until at least November 1941. In May 1946, the U.S. Navy abandoned the airport facilities, leaving all improvements to the County of San Luis Obispo. Disposal records were neither complete nor specific; therefore, Page 602 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 49 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 undiscovered contaminants of concern, resulting from military or other aeronautical operations, may remain in the airport’s subsurface. a) The project does not propose the routine transport, use, or disposal of hazardous substances. Any commonly used hazardous substances within the project site (e.g., cleaners, solvents, oils, paints, etc.) during construction would be transported, stored, and used according to regulatory requirements and existing procedures for the handling of hazardous materials. Mitigation Measure BIO-2 reduces the potential for hazardous materials to enter the on-site jurisdictional aquatic features during project construction. Any commonly used hazardous substances utilized during operation of the project (e.g., cleaners, solvents, oils, paints, etc.) would be transported, stored, and used according to regulatory requirements and existing procedures for the handling of hazardous materials. Therefore, with implementation of Mitigation Measure BIO-2, project impacts associated with the routine transport, use, or disposal of hazardous substances would be less than significant with mitigation. b) The project does not propose the handling or use of hazardous materials or volatile substances that would result in a significant risk of upset or accidental release conditions. Construction activities associated with the project are anticipated to require use of limited quantities of hazardous substances, including gasoline, diesel fuel, hydraulic fluid, solvents, oils, paints, etc. Construction contractors would be required to comply with applicable federal and state environmental and workplace safety laws for the handling of hazardous materials, including the federal Occupational Safety and Health Administration (OSHA) Process Safety Management Standard (California Code of Regulations [CCR] 29.1910.119), which includes requirements for preventing and minimizing the consequences of accidental release of hazardous materials. Further, as introduced in Section 3, Air Quality, the project site is within an area identified as having a potential for NOA to occur. Pursuant to SLOAPCD requirements and the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations, the applicant is required to provide a geologic evaluation prior to any construction activities and comply with existing regulations regarding NOA, if present. Mitigation Measures AQ-3 and AQ-4 have been identified to require the applicant to complete a geologic evaluation and follow all applicable protocol and procedures if NOA is determined to be present on-site. The applicant is also required to comply with SLOAPCD regulations related to materials containing asbestos (Mitigation Measure AQ-5). Any commonly used hazardous substances utilized during operation of the project (e.g., cleaners, solvents, oils, paints, etc.) would be transported, stored, and used according to regulatory requirements and existing procedures for the handling of hazardous materials. Therefore, potential impacts would be less than significant with mitigation. c) The project site is not located within 0.25 mile of an existing or proposed school. The closest school is Los Ranchos Elementary School, located approximately 2 miles southeast of the project site. As a result, there would be no impact associated with hazardous emissions within 0.25 mile of school facilities. d) Based on a search of the DTSC EnviroStor database, SWRCB GeoTracker database, and CalEPA Cortese List website, one inactive hazardous waste site is under investigation in the project vicinity within the San Luis Obispo County Regional Airport at 710 Aerovista Place, located over 1,000 feet south of the project site. In response to growing concern from the public over the presence of halogenated solvents, specifically trichloroethane (TCA) and dichloroethane (DCE) found in nearby drinking water wells, the Central Coast RWQCB submitted a Request for Information to the current owner of the airport property in June 2016 as part of a broader effort to identify the source of the contaminants in the nearby drinking water wells. The property owner submitted a summary of the site history and included two Phase I Environmental Site Assessments (ESAs) from 1993 and 2001. The only halogenated solvents identified as being used at 710 Aerovista Place were TCA and dichlorofluoroethane, but other hazardous materials identified as being used on the parcel include tin and lead, polyurethane paint, isopropyl alcohol, and an acid solution containing chromium (also known as chromic acid solution, which is hexavalent chromium and water). The Phase I ESAs state that hazardous materials appear to have been properly stored on-site and had retained regulatory approval to transport the waste. The Phase I ESAs further concluded that there was no evidence that the parcel was not in compliance with applicable environmental regulations at the time and that no violations or spills were on-file with state and local regulatory agencies. In a letter dated October 26, 2016, the Central Coast RWQCB requested a workplan to investigate groundwater and soil vapor at the airport property. In December 2016, a consultant for the property owner submitted a workplan for a site investigation to the RWQCB detailing the proposed investigation. As of the most recent EnviroStor update on July 11, Page 603 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 50 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 2018, the workplan is pending review and response by the RWQCB. Thus, although the RWQCB is overseeing the activities at the 710 Aerovista Place property, it is not currently categorized as an active case and, as such, is not listed in the SWRCB GeoTracker database. Project construction would require excavation and ground-disturbing activities associated with site preparation (grading) and the installation of utility connections. Excavation activities are not expected to extend downward to the groundwater table. In addition, a Pre-Screening Assessment prepared for the EPA under Cooperative Agreement with DTSC for the site at 710 Aerovista Place notes that the prevailing groundwater flow in the project vicinity is to the southwest, away from the project site. NOA has been identified as a toxic air contaminant by the CARB. Any ground disturbance proposed in an area identified as having the potential to contain NOA must comply with the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations. The SLOAPCD Naturally Occurring Asbestos Map indicates that the project site is located within an area identified as having a potential for NOA to occur. The applicant is required to comply with SLOAPCD regulations related to materials containing asbestos (Mitigation Measure AQ-5). As a result, it is unlikely that project construction would create a significant hazard to the public during construction or operation and potential impacts would be less than significant with mitigation. e) The project site is located approximately 500 feet north of the San Luis Obispo County Regional Airport and within the airport’s Airport Land Use Plan (ALUP). Prior to adoption of the AASP by the City, the Airport Land Use Commission (ALUC) reviewed and approved the AASP and determined it was consistent with the ALUP. The project site is in ALUP Safety Zone S-1c and within the projected 60 decibel (dB) airport noise contour. Per ALUP Table 5.3, Land Use Compatibility Table, a hotel building is a compatible use within Safety Zone S-1c, provided that the maximum non- residential density of use is not exceeded. The project would be developed consistent with the height and density limitations of the AASP and the site’s BP zoning designation, and would not exceed the allowable development intensities, densities, or building footprints. Advancements in construction methods, coupled with energy conservation practices, have had a vast performance impact on the way buildings are constructed. Interior noise levels are substantially reduced through compliance with existing CBC requirements. At the most conservative level, a typical structure covered with siding will have a Sound Transmission Class (STC) rating of 39 A-weighted decibels (dBA) based on current methods. Basic dual-pane vinyl windows will achieve an STC rating of 28 dBA. Averaged out, this results in a combined STC rating of approximately 33 dBA, meaning a typical exterior wall assembly will reduce 33 dB of sound transfer. These numbers are based on a 2- by 4-inch wall cavity with insulation and the rating improves with increased wall thickness and/or stucco or other siding materials. In using more current conventional building standards, double, or even triple the noise reduction can be achieved. Therefore, impacts related to the generation of a substantial temporary or permanent increase in ambient noise levels would be less than significant with standard construction techniques. Therefore, potential impacts associated with safety hazards or excessive noise from aircraft would be less than significant. f) Project construction would result in periodic restrictions on the use of the roadway shoulder for parking along Aero Drive; however, no full road closures would be necessary. Therefore, project implementation would not result in a significant temporary or permanent impact on any adopted emergency response plans or emergency evacuation plans. Any construction-related temporary lane closures would include proper signage and notification and would be short-term and limited in nature and duration. Emergency vehicles have mechanisms to safely traverse areas of congestion, such as the use of sirens and the ability to travel in opposite lanes of travel. The project design plans will be reviewed and approved by the City’s Fire Marshall prior to the start of construction. Therefore, potential impacts would be less than significant. g) The project site is not located within or adjacent to a wildland area, is located within a developing area of the city, and is currently unimproved and requires routine mowing to prevent the growth of brush that could result in a fire hazard to adjacent properties. The project would improve the site with hotel uses, which may slightly reduce the potential for fire hazard in the immediate project vicinity. The project would be required to comply with all applicable fire safety rules and regulations, including the California Fire Code and Public Resources Code, prior to issuance of building permits; therefore, potential impacts would be less than significant. Page 604 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 51 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Mitigation Measures Implement Mitigation Measures AQ-3, AQ-4, AQ-5, and BIO-2. Conclusion The project does not propose the routine transport, use, handling, or disposal of hazardous substances; however, there is the potential for construction equipment to leak or lead to a hazardous materials spill. Implementation of Mitigation Measure BIO-2 would reduce impacts related to accidental construction-related spills to less than significant. The nearest hazardous materials site is located over 1,000 feet south of the project site and construction activities are not anticipated to encounter hazardous materials. The project site is not within 0.25 mile of existing or proposed school facilities. Mitigation Measures AQ-3 and AQ-4 have been identified to require the applicant to complete a geologic evaluation and follow all applicable protocol and procedures if NOA is determined to be present on-site. The applicant is also required to comply with SLOAPCD regulations related to materials containing asbestos (Mitigation Measure AQ-5). Project implementation would not subject people or structures to substantial risks associated with wildland fires and would not impair implementation of or interfere with any adopted emergency response or evacuation plan. Potential impacts associated with hazards and hazardous materials would be less than significant with mitigation. 10. HYDROLOGY AND WATER QUALITY Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? 1, 3, 55, 56 ☐ ☒ ☐ ☐ b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the project may impede sustainable groundwater management of the basin? 1, 34, 35 ☐ ☐ ☒ ☐ c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: i.

The San Luis Obispo Creek watershed is an approximately 53,271-acre coastal basin in southern San Luis Obispo County. It rises to an elevation of about 2,500 feet above sea level in the Santa Lucia Range. San Luis Obispo Creek flows to the Pacific Ocean just west of Avila Beach and has six major tributary basins: Stenner Creek, Prefumo Creek, Laguna Lake, East Branch San Luis Obispo Creek, Davenport Creek, and See Canyon. The City is enrolled in the State General Permit NPDES permit program governing stormwater. As part of this enrollment, the City is required to implement the Central Coast RWQCB’s adopted Post-Construction Stormwater Management requirements through the development review process. The primary objective of these post-construction requirements is to ensure that the permittee is reducing pollutant discharges to the maximum extent practicable and preventing stormwater discharges from causing or contributing to a violation of receiving water quality standards in all applicable development projects that require approvals and/or permits issued. The 100-year flood zone identifies areas that would be subject to inundation in a 100-year storm event, or a storm with a 1% chance of occurring in any given year. Based on the City’s Parcel Viewer Map, the project site is not located within a 100-year flood zone. In 2015, the state legislature approved the Sustainable Groundwater Management Act (SGMA), which requires governments and water agencies of high- and medium-priority basins to halt overdraft and bring groundwater basins into balanced levels of pumping and recharge. Under the SGMA, these basins should reach sustainability within 20 years of implementing their sustainability plans. a) The project does not include substantial vegetation removal and would result in approximately 18,900 cy of earthwork. The City has adopted additional requirements for projects that are subject to an SWRCB General Permit. Per Chapter 12.08 of the City’s Municipal Code, prior to issuance of City permits, the applicant must submit a SWPPP, which includes detailed information describing the potential sources of pollution from project activities and the recommended BMPs. The SWPPP would be adjusted during project activities to adapt to unforeseen conditions and changes in work. The project proposes to disturb more than 1 acre of land; therefore, the applicant would be required to prepare a detailed SWPPP, including potential pollutant discharges and BMPs, to satisfy City requirements. Following project construction, the project site would be developed with buildings, hardscapes, or otherwise landscaped, precluding the potential for substantial erosion or loss of topsoil. The project is required to comply with the Central Coast RWQCB requirements set forth in the Post-Construction Stormwater Management Requirements for Development Projects in the Central Coast Region. Physical improvement of the project site is required to comply with the drainage requirements of the City’s Waterways Management Plan. This plan was adopted for the purpose of ensuring water quality and proper drainage within the City’s watershed. As part of these requirements, the City has been mandated to establish a set of minimum designated BMPs and Pollution Prevention Methods (PPMs). BMPs are steps taken to minimize or control the amount of pollutants and runoff. PPMs are strategies to eliminate the use of polluting materials and/or exposure of potential pollutants to rainwater or other runoff. To meet these requirements, the project would protect existing storm drain lines, manholes, and catch basins in place and proposes additional storm drains, manholes, catch basins, and a storm drain detention system and flared end section. The purpose of these features is to create infrastructure capable of capturing pollutants and conveying stormwater runoff from the project site. Implementation of standard requirements, BMPs and PPMs, standard measures identified in Mitigation Measure BIO-2, and compliance with the City’s Engineering Standards and the Waterways Management Plan related to stormwater management would ensure the project would not substantially affect surface water or groundwater quality. Therefore, potential impacts would be less than significant with mitigation. b) The project would be serviced by the City’s water system, which has four primary water sources, including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water (for irrigation), with groundwater serving as a fifth supplemental source. The City’s diversification of water sources in the last several decades has allowed the City to maintain sufficient water supplies even following the driest years on record. The total water available for the City in the 2020 water year (October 1, 2019, to September 30, 2020) was 10,107 acre-feet per year (AFY), which included 215 AFY of recycled water. As this availability was adjusted following years of drought and updates to the City’s safe annual yield model, the availability is considered a reasonable long-term safe yield value for the purposes of this analysis. The City’s Page 606 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 53 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 water demand for 2020 was 4,730 AF. Stormwater flows within the project site would be contained through the construction of a new stormwater drainage system within the site to allow for percolation back into the groundwater table; therefore, the increase in impervious surface area would not decrease groundwater supplies or interfere substantially with groundwater recharge in the project vicinity. Therefore, the project would not deplete groundwater resources, and impacts would be less than significant. c.i-iii) The project, as proposed, would not result in direct impacts to the ephemeral drainage located within the project site. The drainage would be protected by a 35-foot setback during project construction and operation. However, project construction consists of excavation and other ground-disturbing activities that could result in temporary impacts to drainage patterns in the area through erosive runoff. In accordance with the City’s Municipal Code (Chapter 12.08), the project must develop and implement a SWPPP that includes BMPs to protect stormwater runoff, including measures to prevent soil erosion. In addition, Mitigation Measure BIO-2 would be implemented to minimize impacts of erosive runoff resulting from excavation and other groundwork. Following project construction, the project site would be developed with buildings, hardscapes, or otherwise landscaped, precluding the potential for substantial erosion or loss of topsoil. Implementation of the project would result in new impervious surfaces, including paved roads, hardscapes, and buildings that have potential to increase polluted runoff. To meet the requirements of the City’s Municipal Code (Chapter 12.08), the project would protect existing storm drain lines, manholes, and catch basins in place and proposes additional storm drains, manholes, catch basins, and a storm drain detention system and flared end section. The purpose of these features is to create infrastructure capable of conveying stormwater runoff from the project site to the City’s utility connections that can support the additional wastewater. Implementation of a SWPPP and Mitigation Measures BIO-2 would minimize potential impacts to drainages during project construction; therefore, project impacts would be less than significant with mitigation. c. iv) Based on the City’s Parcel Viewer Map, the project site is not located within a 100-year flood zone. Additionally, the drainage located within the project site would be protected by a 35-foot setback during project construction and operation. Therefore, potential impacts associated with impeding or redirection of flood flows would be less than significant. d) Based on the San Luis Obispo County Tsunami Inundation Maps, the project site is not located in an area with potential for inundation by a tsunami. The project site is not located within close proximity to a standing body of water with the potential for a seiche to occur. Therefore, there would be no impacts associated with tsunami, seiche zones, or risk of pollutant release due to project inundation. e) Per the City’s General Plan Water and Wastewater Management Element, Policy A2.2.1, the City has four primary water supply sources, including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water. Groundwater serves as a fifth supplemental source. The City’s diversification of water sources in the last several decades has allowed the City to maintain sufficient water supplies even following the driest years on record. The total water available for the City in the 2020 water year (October 1, 2019, to September 30, 2020) was 10,107 AFY, which included 215 AFY of recycled water. As this availability was adjusted following years of drought and updates to the City’s safe annual yield model, the availability is considered a reasonable long-term safe yield value for the purposes of this analysis. The City’s water demand for 2020 was 4,730 AF The project includes stormwater treatment and storage facilities and would not conflict with the City’s Waterways Management Plan or other water quality control plans. The project would not conflict with the SGMA, Central Coast Basin Plan, or other local or regional plans or policies intended to manage water quality or groundwater supplies; therefore, impacts would be less than significant. Mitigation Measures Implement Mitigation Measure BIO-2. Conclusion Through project design, implementation of Mitigation Measure BIO-2, standard BMPs, PPMs, and City Engineering Standards, the project would not substantially impede or redirect flood flows, alter existing drainage patterns, degrade surface water quality, decrease groundwater supplies, or conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. The project would retain the preconstruction infiltration rates and volume currently occurring on the unimproved project site. Therefore, potential impacts related to hydrology and water quality would be less than significant with mitigation.

LAND USE AND PLANNING Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Physically divide an established community? ☐ ☐ ☐ ☒ b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? 1, 3, 6 ☐ ☒ ☐ ☐ Evaluation The project site is comprised of two unoccupied, undeveloped parcels located in the BP zone of the AASP and is generally surrounded by one- and two-story commercial office uses, with a few remaining unimproved parcels, as summarized below: • Northeast: one- and two-story commercial offices and buildings; • Northwest: one- and two-story commercial office buildings and restaurant buildings (i.e., SLO Brew Rock); • Southwest: ephemeral drainage, San Luis Obispo County Regional Airport, and ancillary features (i.e., airport parking lot, buildings); and • Southeast: one- and two-story commercial offices and buildings. a) The project would result in the construction and operation of a hotel facility within a currently undeveloped site in the city of San Luis Obispo. The project would be surrounded by other commercial land uses and would not physically divide an established community. The project would be consistent with the general level of development within the project vicinity and would not create, close, or impede any existing public or private roads, or create any other barriers to movement or accessibility within the community. Therefore, the project would not physically divide an established community and no impacts would occur. b) The project would be consistent with the property’s BP land use designation and the guidelines and policies for development within the applicable zoning designation, AASP, Land Use Element, and COSE. The project is consistent with existing surrounding development and proposes a compatible land use. Hotel uses are permitted in the BP zone in the AASP with approval of a CUP; therefore, the project would be consistent with existing land uses and designations for the project site and, therefore, would not conflict with any applicable land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating environmental effects. The COSE includes various goals and policies to maintain, enhance, and protect natural communities within the City’s planning area. These policies include, but are not limited to, protection of listed species and SSC, preservation of existing wildlife corridors, protection of significant trees, and maintaining development setbacks from creeks. The project site is largely disturbed and does not support highly sensitive environmental resources. The unnamed ephemeral drainage and wetland area at the southwest corner of the project site would be retained in place and protected/enhanced to provide a protected seasonal wetland area. The on-site drainage and associated wetland area would be setback 35 feet from project construction and operations, and implementation of Mitigation Measures BIO-1 through BIO-3 would ensure indirect effects to the drainage, special-status species, and nesting migratory birds resulting from construction activities would be avoided and/or minimized and the project would not result in a conflict with local policies or ordinances protecting biological resources and impacts. Therefore, the project would not conflict with policies or regulations adopted for the purpose of avoiding or mitigating environmental effects and impacts would be less than significant with mitigation. Mitigation Measures Implement Mitigation Measures BIO-1 through BIO-3. Page 608 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 55 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Conclusion The proposed project would not physically divide an established community and would be consistent with surrounding land uses. The project would be consistent with the existing BP zoning designation with City approval of a CUP. The proposed 35-foot design setback from the ephemeral channel within the project site, and implementation of Mitigation Measures BIO-1 through BIO-3 would ensure potential impacts to jurisdictional aquatic habitat, special-status species, and nesting migratory birds would ensure the project would not result in a conflict with local policies or ordinances protecting biological resources and potential impacts would be less than significant. 12. MINERAL RESOURCES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? 3 ☐ ☐ ☐ ☒ b) Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? 3 ☐ ☐ ☐ ☒ Evaluation Based on the City COSE, mineral extraction is prohibited within city limits. a,b) No known mineral resources are present within the project site and future extraction of mineral resources is very unlikely due to the urbanized nature of the area. Therefore, no impacts would occur. Mitigation Measures Mitigation measures are not required. Conclusion No impacts to mineral resources were identified; therefore, mitigation measures are not required. 13. NOISE Would the project result in: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? 6, 38, 39 ☐ ☐ ☒ ☐ b) Generation of excessive groundborne vibration or groundborne noise levels? 39, 40, 41 ☐ ☐ ☒ ☐ Page 609 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 56 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Would the project result in: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact c) For a project located within the vicinity of a private airstrip or an airport land use plan, or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? 32 ☐ ☐ ☒ ☐ Evaluation The City’s Noise Element establishes standards for maximum acceptable noise levels associated with stationery and transportation sources. Noise created by new transportation noise sources are required to be mitigated to not exceed the maximum acceptable noise levels identified in Table 7. Table 7. Maximum Noise Exposure for Noise-Sensitive Uses due to Transportation Noise Sources Noise-Sensitive Use Outdoor Activity Areas1 Indoor Spaces Ldn or CNEL, in dB Ldn or CNEL, in dB Leq in db2 Lmax in dB3 Residences, hotels, motels, hospitals, nursing homes 60 45 -- 60 Theaters, auditoriums, music halls -- -- 35 60 Churches, meeting halls, office building, mortuaries 60 -- 45 -- Schools, libraries, museums -- -- 45 60 Neighborhood parks 65 -- -- -- Playgrounds 70 -- -- -- Notes: CNEL = Community Noise Equivalent Level; Ldn = day-night average sound level; Leq = equivalent continuous sound level; Lmax = maximum sound level. 1 If the location of outdoor activity areas is not shown, the outdoor noise standard shall apply at the property line of the receiving land use. 2 As determined for a typical worst-case hour during periods of use. 3 Lmax indoor standard applies only to railroad noise at locations south of Orcutt Road. Outdoor activity areas are not defined in the City’s Noise Element but are defined in the City of San Luis Obispo, Noise Guidebook, Measurement & Mitigation Techniques. The guidebook states that outdoor activity areas are “patios, decks, balconies, outdoor eating areas, swimming pool areas, yards of dwellings, and other areas commonly used for outdoor activities and recreation.” The City’s Noise Element also identifies Policy 1.4 regarding noise created by new transportation sources, including road, railroad, and airport expansion projects, which states noise from these sources shall be mitigated to not exceed the levels specified in Table 7 for outdoor activity areas and indoor spaces of noise-sensitive land uses. The project site is located in an area where airport operations and roadway traffic dominate the existing noise environment. Hotels are considered a noise-sensitive land use by the City’s Noise Element. Per City Municipal Code Chapter 9.12 Noise Control, operating tools or equipment used in construction between weekday hours of 7:00 p.m. and 7:00 a.m. or any time on Sundays or holidays is prohibited, except for emergency works of public service utilities or by exception issued by the Community Development Department. The Municipal Code also states that construction activities shall be conducted in such a manner, where technically and economically feasible, that the maximum noise levels at affected properties will not exceed 85 dBA at mixed residential/commercial uses. Based on the City Municipal Code (9.12.050.B.7), operating any device that creates vibration which is above the vibration perception threshold of an individual at or beyond 150 feet from the source if on a public space or right-of-way is prohibited. Page 610 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 57 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 a) The project includes site preparation and construction of the proposed hotel buildings. During project construction, noise from construction activities may intermittently dominate the noise environment in the immediate area. Typical noise levels produced by equipment commonly used in construction projects are shown in Table 8. Table 8. Construction Equipment Noise Emission Levels Equipment Type Typical Noise Level (dBA) 50 ft From Source Backhoe 80 Compactor 80 Concrete Mixer 85 Concrete Pump 82 Crane, Mobile 83 Dozer 85 Excavator 85 Heavy Truck 84 Jackhammer 85 Man Lift 85 Paver 85 Scraper 85 As shown above, construction equipment that would be utilized during project construction would not exceed 85 dB and would be similar to other construction activity within the city. Further, the nearest sensitive receptors (i.e., the single- family homes across Broad Street) are located approximately 540 feet northeast of the project site, with the direct line of sight obstructed by existing development. Thus, construction noise, which would be short-term, intermittent, and would only occur during daytime hours per the City Municipal Code (when ambient noise levels are higher), would be largely undetectable at proximate sensitive receptors. The project does not include components that would significantly add to long-term ambient noise in the project vicinity. Upon completion of construction activities, the project would include the use of heating, ventilation, and air conditioning (HVAC) systems that would have the potential to contribute additional noise to the existing noise environment, as well as mobile noise from project-related traffic. The additional noise generated by the project’s HVAC systems would not result in a noticeable increase in ambient noise levels. Relative to vehicular noise, a doubling of traffic is typically needed to produce a noise increase that is audible to the human ear. The project would not result in a doubling of traffic trips; therefore, no substantial increase in mobile source noise would occur. Potential impacts associated with generation of a substantial temporary or permanent increase in ambient noise levels in the project vicinity in excess of standards established would be less than significant. b) The project does not propose pile driving or other high-impact activities that would generate substantial noise or groundborne vibration during construction. Use of heavy equipment would generate groundborne noise and vibration; however, there are no buildings that surround the project site (i.e., historical buildings and occupants of surrounding buildings) that would be substantially affected by this groundborne vibration. Based on the proposed construction activities, groundborne vibration is expected to be imperceptible at adjacent properties. Therefore, potential impacts would be less than significant. Page 611 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 58 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 c) The project site is located within the ALUP Safety Zone S-1c, within the projected 60 dB airport noise contour. The project would be consistent with the property’s BP land use designation and the guidelines and policies for development within the applicable zoning designation, AASP, Land Use Element, and COSE. The project is consistent with existing surrounding development and proposes a compatible land use. As discussed above, the project does not include components that would significantly add to long-term ambient noise in the project vicinity. Operational noise is anticipated to be limited to the use of HVAC systems and operational traffic; however, these uses, combined with noise associated with nearby airport operations, are not anticipated to expose people residing or working in the project area to excessive noise levels; therefore, impacts would be less than significant. Mitigation Measures Mitigation measures are not required. Conclusion The project would not exceed City Municipal Code construction and operational noise standards for commercial development. Further, the project’s proposed hotel uses are consistent with the ALUP allowable uses within the 60 dB noise contour. No potentially significant impacts associated with noise would occur and mitigation measures are not required. 14. POPULATION AND HOUSING Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? 42, 43 ☐ ☐ ☒ ☐ b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? 1 ☐ ☐ ☐ ☒ Evaluation San Luis Obispo is the largest city in terms of population in San Luis Obispo County and has grown from 45,119 in 2010 to approximately 46,802 in 2019 according to the City’s General Plan 2019 Annual Report. The City’s housing tenure is approximately 39% owner-occupied and 61% renter-occupied, which is strongly influenced by California Polytechnic State University, San Luis Obispo (Cal Poly) and Cuesta College enrollment. Many segments of the city’s population have difficulty finding affordable housing within the city due to their economic, physical, or sociological circumstances. San Luis Obispo contains the largest concentration of jobs in the county and, during workdays, the city’s population increases to an estimated 70,000 persons. The City’s Housing Element identifies various goals, policies, and programs based on an assessment of the City’s housing needs, opportunities, and constraints. The City’s overarching goals for housing include safety, affordability, conservation of existing housing, accommodation for mixed-income neighborhoods, providing housing variety and tenure, planning for new housing, maintaining neighborhood quality, providing special needs housing, encouraging sustainable housing and neighborhood design, maximization of affordable housing opportunities for those who live or work in the City, and developing housing on suitable sites. a) The proposed project is consistent with the project site’s BP land use and zoning designation. Thus, any indirect population growth resulting from an increase in on-site employment has been planned for with the annexation of the area and with the adoption of the AASP. The project would be consistent with the projected population growth for the city. The project would not result in substantial unplanned population growth; therefore, potential impacts would be less than significant. Page 612 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 59 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 b) The project would not result in the displacement of any existing or proposed housing; therefore, no impacts would occur. Mitigation Measures Mitigation measures are not required. Conclusion The project would be consistent with the City’s projected population growth. No potentially significant impacts would occur, and mitigation measures are not required. 15. PUBLIC SERVICES Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: Fire protection? 1, 44 ☐ ☐ ☒ ☐ Police protection? 1, 44 ☐ ☐ ☒ ☐ Schools? 1, 44 ☐ ☐ ☒ ☐ Parks? 1, 44, 45 ☐ ☐ ☒ ☐ Other public facilities? 1, 44 ☐ ☐ ☒ ☐ Evaluation The project site is located within the existing service area of the City’s Fire Department (SLOFD). The SLOFD deploys resources and personnel from four fire stations in order to maintain the response time goal of 4 minutes travel time to 95% of all emergencies. The nearest City fire station to the project site is City Fire Station 3, located at 1280 Laurel Lane, approximately 2 miles north of the project site. City Fire Station 3 provides primary response to the southern portion of the city. This station is staffed by a three-person paramedic engine company. County Fire Station 21 is located at 4671 Broad Street, approximately 0.4 mile southeast of the project site. County Fire Station 21 provides additional fire protection through an automatic aid agreement with the City. The City’s Police Department (SLOPD) provides public safety services for the city and is comprised of 85.5 employees, 59 of which are sworn police officers. The SLOPD operates out of one main police station, located at 1042 Walnut Street at the intersection of Santa Rosa (Highway 1) and U.S. 101, and emergency response times to the site would be less than 5 minutes. The project site is located within the San Luis Coastal Unified School District (SLCUSD), and public parks and recreation trails within the city are managed and maintained by the City’s Parks and Recreation Department. All new residential and non-residential development within the city is subject to payment of Development Impact Fees, which are administered by and paid through the City’s Community Development Department. Development Impact Fees provide funding for maintaining City emergency services, infrastructure, and facilities. For example, fire protection impact fees provide funding for projects such as the renovation of the City’s fire stations and the replacement of fire service vehicles and equipment. a) Fire protection: The project would be served by the SLOFD; the closest station is Fire Station 3, located at 1280 Laurel Lane. The project proposes a new hotel with surface parking that is consistent with the applicable BP land use and zoning designations within the AASP, and the proposed level of development would be compatible with surrounding commercial Page 613 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 60 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 developments. While the project would not directly result in the need for construction of new fire service facilities, development of a new hotel would result in a marginal cumulative increase in demand on City services, including fire protection. The project would be required to participate in the City’s system of required developer impact fees and dedications established to address direct demand for new facilities associated with new development. Potential increases in property tax revenue associated with valuation of the new businesses and other revenues (e.g., sales tax) would also help offset the increased ongoing cost of provision of public services to the new commercial building. Therefore, impacts associated with the provision of new or physically altered fire protection facilities would be less than significant. Police protection: The project would be served by the SLOPD. Proposed development of a new hotel would result in a marginal increase in demand on City services, including police protection. The project proposes uses generally consistent with the surrounding AASP area and the proposed level of development would be similar to surrounding commercial development. As discussed above, the project would be subject to required developer impact fees established to address direct demand for new facilities associated with new development. Potential increases in property tax revenue associated with valuation of the new businesses and other revenues (e.g., sales tax) would also help offset the increased ongoing cost of provision of public services to new commercial uses. Therefore, a new or physically altered police protection facility would not be required to accommodate the project and impacts would be less than significant. Schools: The project site is located within the SLCUSD and would be subject to payment of SLCUSD developer fees to offset the potential marginal increase in student attendance in the SLCUSD’s schools as a result of the project. These fees would be directed towards maintaining sufficient service levels, which include incremental increases in school capacities. The proposed project would not induce unplanned population growth because employees are likely to come from the local workforce and the customer base would not affect enrollment at local schools. Through participation in the existing fee program, potential project impacts on schools would be less than significant. Parks: Proposed development of a new hotel may result in an incremental increase of demand on local parks and recreational facilities in the area. Although employees are likely to come from the local workforce, customers at the new hotel facility may visit local parks and recreational facilities. The project would not induce unplanned population growth and is not expected to result in a significant increase in demand on local parks and recreational facilities. The project is consistent with the City’s General Plan designation, AASP, and zoning designation; any indirect population growth resulting from the project would be consistent with the projected population growth for the city. Therefore, potential project impacts on parks would be less than significant. Other public facilities: The project would not induce unplanned population growth and would result in a negligible effect on use of other public facilities, such as roadways and public libraries. The project would be subject to the City’s standard development fees, which would offset the project’s marginal contribution to increased use of City facilities. Therefore, potential project impacts on public facilities would be less than significant. Mitigation Measures Mitigation measures are not required. Conclusion The project would not induce unplanned population growth because employees are likely to come from the local workforce. Operation of the project may result in a marginal cumulative increase in demand on City services and facilities, including fire protection, police protection, schools, parks and recreational facilities, and other public facilities; however, construction of new facilities is not anticipated to be required. The project would be subject to required developer impact fees established to address direct demand for new facilities associated with new development. Potential increases in property tax revenue associated with valuation of the new businesses and other revenues (e.g., sales tax) would also help offset the increased ongoing cost of provision of public services to new commercial uses. The project would not result in significant impacts to public services; therefore, mitigation measures are not required.

RECREATION Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? 1, 44, 45 ☐ ☐ ☒ ☐ b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? 1, 44, 45 ☐ ☐ ☒ ☐ Evaluation Existing City recreational facilities consist of 28 parks and recreational facilities, in addition to 10 designated natural resources and open space areas and two bike trails. The City’s Recreation Element identifies goals, policies, and programs to help plan, develop, and maintain community parks and recreation facilities. The City’s statement of overall department goals is for the City Parks and Recreation facilities and programs to enable all citizens to participate in fun, healthful, or enriching activities, which enhance the quality of life in the community. As demand for recreation facilities and activities grow and change, the City intends to focus its efforts in the following areas: continued development of athletic fields and support facilities, providing parks in underserved neighborhoods, providing a multi- use community center and therapy pool, expanding paths and trails for recreational use, linking recreation facilities, and meeting the special needs of disabled persons, at-risk youth, and senior citizens. City Parks and Recreation Element Policy 3.13.1 establishes the City’s goal to develop and maintain a park system at the rate of 10 acres of parkland per 1,000 residents, 5 of which shall be dedicated as neighborhood parks. a, b) Proposed development of a new hotel is not anticipated to result in a significant increase in demand on local parks and recreational facilities in the area. Employees for construction and operation of the hotel are anticipated to come from the local workforce; however, customers of the new hotel may result in a marginal increase in the use of local recreational facilities. As the project is consistent with the City’s General Plan designation and underlying zoning, any indirect population growth resulting from the project would be consistent with the projected population growth for the City. Therefore, potential project impacts associated with accelerated deterioration of existing facilities or construction of new park facilities would be less than significant. Mitigation Measures Mitigation measures are not required. Conclusion The project would not induce unplanned population growth because employees are likely to come from the local workforce. Operation of the project may result in a marginal cumulative increase in demand on City recreational facilities; however, construction of new facilities is not anticipated to be required. The project would not result in significant impacts to recreational facilities; therefore, mitigation measures are not required.

TRANSPORTATION Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? 13, 46 ☐ ☐ ☒ ☐ b) Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? 1, 13, 46, 54, 57 ☐ ☒ ☐ ☐ c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? 1, 24, 46 ☐ ☐ ☒ ☐ d) Result in inadequate emergency access? 1, 24, 46 ☐ ☐ ☒ ☐ Evaluation This evaluation is based, in part, on the Multimodal Transportation Impact Study for the SLO Airport Hotels Project prepared by W-Trans in May 2020 (included as Attachment 7.1), the 950 Aero Hotel VMT Analysis prepared by GHD in December 2020 (included as Attachment 7.2), the Recommended Transportation Demand Measures prepared for the 950 Aero SLO Hotel Project by GHD in December 2020 (included as Attachment 7.3), and the Automobile Trip Reduction Plan prepared for the SLO Airport Hotel Project by Arris Studio Architects in February 2020 (included as Attachment 7.4). The City’s Circulation Element identifies current traffic levels and delays of public roadways and identifies transportation goals and policies to guide development and express the community’s preferences for current and future conditions. Goals included in the plan include, but are not limited to, maintaining accessibility and protecting the environment throughout San Luis Obispo while reducing dependence on single-occupant use of motor vehicles; reducing use of cars by supporting and promoting alternatives such as walking, riding buses and bicycles, and carpooling; promoting the safe operation of all modes of transportation; and widening and extending streets only when there is a demonstrated need and when the projects would cause no significant, long-term environmental problems. Level of Service (LOS) is a term used to describe the operating conditions of an intersection or roadway based on factors such as speed, travel time, queuing time, and safety. LOS designations range between A and F, with A representing the best operating conditions and F the worst. The City’s Circulation Element establishes the minimum acceptable LOS standard for vehicles in the downtown area of the city as LOS E and LOS D for all other areas and states any degradation of the LOS below these standards shall be interpreted as transportation operations deficiency under local policy thresholds. While LOS deficiencies are evaluated for local policy conformity, LOS or other measures of automobile congestion/delay are not applied when evaluating transportation impacts under CEQA. The City of San Luis Obispo Bicycle Transportation Plan outlines the City’s official policies for the design and development of bikeways within the city and in adjoining territory under County of San Luis Obispo jurisdiction but within the City’s Urban Reserve and includes specific objectives for reducing vehicle use and promoting other modes of transportation. A Class I bike path provides a completely separated right-of-way for the exclusive use of bicycles and pedestrians with crossflow by motorists minimized. A Class II bike lane provides an on-street striped lane for one-way bicycle travel on the side of the street adjacent to vehicle traffic. In 2013, SB 743 was signed into law with the intent to “more appropriately balance the needs of congestion management with statewide goals related to infill development, promotion of public health through active transportation, and reduction of greenhouse gas emissions” and required the Governor’s Office of Planning and Research (OPR) to identify new metrics for identifying and mitigating transportation impacts within CEQA. As a result, in December 2018, the California Natural Resources Agency certified and adopted updates to the State CEQA Guidelines. The revisions included new requirements related to the implementation of SB 743 and identified VMT per capita, VMT per employee, and net VMT as new metrics for transportation Page 616 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 63 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 analysis under CEQA (as detailed in Section 15064.3[b]). In June 2020, the City formally adopted the transition from LOS to VMT for the purposes of CEQA evaluation and also establish local VMT thresholds of significance. The project site would be accessed by Aero Drive, a two-way local roadway that, in combination with Aerovista Place, provides a two-lane loop surrounding the project site and buildings north of the project site, with both the northern and southern termini ending at an intersection with Broad Street. At the project site, the City’s Circulation Element designates Aero Drive as LOS A. LOS A streets are characterized as free-flow travel with excellent level of comfort and convenience. Based on the City’s Traffic County & Speed Surveys Map, the average daily motor vehicle trip volume (ADT) on Aero Drive west of Broad Street is 2,193. Average daily pedestrian volume is six trips, and average daily bicycle volume is seven trips. On Broad Street adjacent to the project site, ADT volume is 19,739, average daily pedestrian volume is 19, and 63 trips for bicycles. On Broad Street southeast of the project site, ADT volume is 18,239 trips for motor vehicles, eight trips for pedestrians, and 54 trips for bicycles. All roadways in the immediate project vicinity have curbs, gutters, sidewalks, and on-street parking. Broad Street in the project vicinity is a north–south roadway designated as a Highway (Highway 227) and provides two lanes of travel in each direction with a center turn lane. The northern intersection of Broad Street and Aerovista Place is a three-way intersection with stop sign control for drivers on Aerovista Place turning onto Broad Street. A dedicated left-turn lane is provided on northbound Broad Street. The southern intersection of Broad Street and Aero Drive is a signalized four-legged intersection that serves as the primary access to the San Luis Obispo County Regional Airport terminal. Broad Street has designated Class II bike lanes in both directions. a) The project proposes infill development in the AASP area of the city, in an area surrounded by commercial office and building uses. The project site would be accessed by a new driveway off Aero Drive. The project would be consistent with the goals and policies outlined in the City’s Circulation Element regarding traffic congestion reduction through compliance with City Zoning Regulations requiring provision of secure bicycle storage, showers, and locker and changing room facilities to encourage project employees to use alternative modes of transportation. The project would also be required to reduce traffic congestion by providing guests with alternative modes of transportation such as a shuttle or rideshare service. The project site is located within immediate proximity of Class II bicycle lanes on Broad Street, as identified in the City’s Active Transportation Plan. The project would require the payment of the City’s standard Traffic Impact Fees (TIF). The project does not include any changes to the land use or zoning designation, or associated development standards as identified in the AASP, and is consistent with the AASP Certified Environmental Impact Report (EIR). Therefore, with the payment of standard TIFs, project impacts associated with conflicts with any program, plan, ordinance, or policy addressing transportation facilities would be less than significant. b) VMT is disclosed and assessed in comparison to citywide and countywide averages. Based on the Draft 2016 Community Greenhouse Gas Emissions Inventory Update, total VMT in San Luis Obispo County in 2016 was approximately 8.3 million; VMT in the city in 2016 was approximately 0.5 million. As reported by the City’s Traffic Demand Model, the forecasted 2035 Daily VMT is approximately 12 million miles for the region and approximately 1.5 million miles for the City’s sphere of influence. The average VMT per household is 80 for the region and 54 for the City’s sphere of influence. According to VMT analysis conducted by GHD for the proposed project, the project would result in a net increase of 393 VMT, constituting a 0.005% increase. This increase in traffic generated by the proposed project would exceed the City’s adopted VMT thresholds by the equivalent of approximately 48 daily auto trips, resulting in a significant impact. According to the Multimodal Transportation Impact Study prepared for the project (W-Trans 2020), the project is expected to generate an average of 1,822 daily trips. Based on an assessment of trip lengths from the project’s traffic analysis zone within the model it is estimated the average project trip length is approximately 8.3 miles. Therefore, approximately 48 project trips are contributing to the net increase in regional VMT. The project will need to implement transportation demand management (TDM) measures to reduce VMT by 393 or approximately 48 daily trips (3% reduction). Mitigation Measures TR-1 and TR-2 have been included to ensure the project does not result in a net increase in regional VMT. As described in the Recommended Transportation Demand Measures document prepared for the proposed project, the TDM measures would result in a VMT reduction of 4.93%. Further, through compliance with City Zoning Regulations requiring provision of secure bicycle storage, showers, and locker and changing room facilities to encourage project employees to use alternative modes of transportation, as well as being within immediate proximity of the Class II bicycle lane on Broad Street, the project would promote alternate modes of travels that would further reduce VMT. Therefore, the project would be consistent with the standards set forth in State CEQA Guidelines Section15064.3(b) and impacts would be less than significant with mitigation. Page 617 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 64 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 c) During construction, the project would result in periodic access restrictions along road shoulders and parking areas along Aero Drive. Periodic closures of road shoulders and parking areas and the use and transport of construction vehicles and equipment would not substantially affect local traffic on Aero Drive. The project proposes a driveway entrance on a straight segment of Aero Drive that does not contain dangerous curves, short sight distance, or other dangerous design features. The driveway would be designed in accordance with the City’s Public Works safety design standards, including the use of red “no parking” curb paint on either side of the driveway entrance to allow for safe turning movements and provide motorists an adequate line of sight from the driveway. The project will be reviewed by the Transportation and Engineering Divisions prior to approval of any building permits. Therefore, project impacts associated with increased hazards due to a geometric design feature would be less than significant. d) The project has been designed to comply with the State and City Fire Codes and would be subject to review by the City Fire Marshal to ensure adequate emergency access has been provided. Therefore, potential impacts related to inadequate emergency access would be less than significant. Mitigation Measures TR-1 Trip Reduction Coordinator. The project applicant shall identify a Trip Reduction Coordinator to act as the contact person for the City of San Luis Obispo and SLO Regional Rideshare. The Coordinator shall be responsible for: 1. Implementing an annual vehicle trip survey (can be administered through SLO Regional Rideshare.) 2. Preparing an annual report, subject to the City’s review and approval, on the program’s effectiveness and recommendations for revisions if needed to improve the program’s effectiveness. 3. Providing quarterly information (electronically or hard copy) regarding area transportation services and City and County transit passes. 4. Coordinating employee transportation board meetings. 5. Coordinator will be responsible for establishing the Back ‘N’ Forth Club (for employees sponsored by Rideshare for the complex at a minimum of the Silver level). TR-2 Transportation Demand Management (TDM) measures shall be implemented to reduce the project’s trip generation by at least 3% and may include, but are not limited to, the measures identified in GHG-1 and the following measures: 1. Shuttle Service. The hotel shall offer a shuttle service to the airport terminal and downtown as requested by the guests. The hotel will also coordinate with local wine tours to encourage guests interested in wine tasting to utilize communal travel options rather than individual vehicles. 2. Community Transportation Board. A group of managers and employees, including the Trip Reduction Coordinator who meets to discuss and implement new ways to encourage employees and guests to participate in the community’s alternative transportation programs. 3. Shared Automobile. On-site accommodations will be made available for a communal short-term rental car to enable guests to utilize a shared vehicle for short errands and other related needs. It is estimated that utilizing a car-sharing program alone will offset up to 10 required parking spaces. One company that offers this service is Zipcar. Information on their services can be found on their website (https://www.zipcar.com/) or similar. 4. Bicycle Repair Station. A convenient station equipped with all of the tools necessary for employees to perform basic bike repairs and maintenance. 5. Long-term Bicycle Parking. The project shall provide adequate, secure long-term bicycle parking for employees. 6. Showers and Locker Facilities. The hotel will include shower and locker facilities for employees that bike to work. 7. Shared Bicycles for Guests. The hotel will own and maintain bicycles available for guests to use to as an alternative to using vehicles. 8. SLO Rideshare Back ‘N’ Forth Club. The project shall participate in the SLO Rideshare Back ‘N’ Forth Club. 9. Transit Passes. The project shall provide free or discounted transit passes to employees. Page 618 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 65 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 10. Information Packets. Introductory packets, in either electronic or hardcopy form, for new employees with information pertaining to the car-sharing program, bicycle parking, bicycle repair station and a map showing the nearby bus stops. 11. Information Sharing. Management will distribute emails to keep the employees informed of activities. These emails will include up-to-date facts on car sharing availability, bicycle parking locations, alternative transportation programs and transit schedules. These emails will also include maps showing walking and bicycle routes to nearby retail, dining, and service locations. These emails will be distributed to all residents. Conclusion The project would result in a net increase in trips and VMT and would exceed the City’s established thresholds for VMT; therefore, the project would be inconsistent with the City’s Circulation Element and CEQA Guidelines Section 15064.3 subdivision (b) regarding VMT. Mitigation has been included to ensure payment of appropriate TIF fees and implementation of Transportation Demand Management measures to reduce VMT by at least 3%. The project would be required to meet City Public Works safety design standards and would maintain adequate emergency access. Therefore, potential impacts associated with transportation would be less than significant with mitigation. 18. TRIBAL CULTURAL RESOURCES Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, or cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)? 3 ☐ ☒ ☐ ☐ b) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1? In applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe. 3 ☐ ☒ ☐ ☐ Evaluation Approved in 2014, AB 52 added tribal cultural resources to the categories of resources that must be evaluated under CEQA. Tribal cultural resources are defined as either of the following: 1) Sites, features, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are either of the following: a. Included or determined to be eligible for inclusion in the California Register of Historical Resources; or b. Included in a local register of historical resources as defined in subdivision (k) of California Public Resources Code Section 5020.1. 2) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of California Public Resources Code Section 5024.1. In applying these criteria for the purposes of this paragraph, the lead agency shall consider the significance of the resource to a California Native American Tribe. Recognizing that tribes have expertise with regard to their tribal history and practices, AB 52 requires lead agencies to provide notice to tribes that are traditionally and culturally affiliated with the geographic area of a proposed project if they have requested notice of projects proposed within that area. If the tribe requests consultation within 30 days upon receipt of the notice, the lead Page 619 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 66 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 agency must consult with the tribe regarding the potential for adverse impacts on tribal cultural resources as a result of a project. Consultation may include discussing the type of environmental review necessary, the presence and/or significance of tribal cultural resources, the level of significance of a project’s impacts on the tribal cultural resources, and available project alternatives and mitigation measures recommended by the tribe to avoid or lessen potential impacts on tribal cultural resources. Native American Tribes were notified about the project consistent with State and City regulations under AB 52. As of January 18, 2021, the City has received one response from Patti Dunton of the Salinas Tribe of San Luis Obispo and Monterey Counties. a,b) The City has provided notice of the opportunity to consult to appropriate tribes per the requirements of AB 52 and received one response from Patti Dunton of the Salinas Tribe of San Luis Obispo and Monterey Counties, as of January 18, 2021. Ms. Dunton submitted a response via email on January 11, 2021, requesting mitigation measures be included for the project so that, if any resources are unearthed, all work in the area shall stop until a qualified archaeologist can evaluate the find and if any human remains are unearthed, all work shall stop, and state laws shall be adhered to. The project site does not contain any known tribal cultural resources that have been listed or been found eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in PRC Section 5020.1. Mitigation Measures CR-1 through CR-3 have been identified to require cultural resource awareness training, and cessation of work if a discovery is made until a qualified archaeologist can assess the significance of the find. Therefore, impacts related to a substantial adverse change in the significance of tribal cultural resource would be less than significant with mitigation. Mitigation Measures Implement Mitigation Measures CR-1 through CR-3. Conclusion With implementation of Mitigation Measures CR-1 through CR-3, the project would have a less-than-significant impact on tribal cultural resources. 19. UTILITIES AND SERVICE SYSTEMS Would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? 47, 50, 51 ☐ ☒ ☐ ☐ b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry, and multiple dry years? 49, 50 ☐ ☐ ☒ ☐ c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? 47, 50, 57 ☐ ☐ ☒ ☐ d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? 48, 49, 50 ☐ ☐ ☒ ☐ e) Comply with federal, state, and local management and reduction statutes and regulations related to solid waste? 3, 49, 50 ☐ ☐ ☒ ☐ Page 620 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 67 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Evaluation The City’s Utilities Department is the sole water provider within the city, provides potable and recycled water to the community, and is responsible for water supply, treatment, distribution, and resource planning. The City’s Water Resource Recovery Facility (WRRF) treats all of the wastewater from the city, Cal Poly, and the airport. The facility treats 4.5 million gallons of wastewater per day. The WRRF manages and treats wastewater in accordance with standards established by the SWRCB to remove solids, reduce the amount of nutrients, and eliminate bacteria in treated wastewater. A portion of the treated water is recycled for irrigation use within the city and the remaining flow is discharged to San Luis Obispo Creek. Water service for the project would be provided by the City’s Utilities Department and the project would be served by the City’s sewer system. The project site has existing utility infrastructure on-site, including a storm drain line, a storm drain manhole, a storm drain catch basin, a sewer line located off of Broad Street, a sewer cleanout, a water line, a recycled water line, a water valve, a fire hydrant, a water meter, an electrical line, and a gas line. a) The project includes the installation of new water, wastewater, stormwater, and energy extensions and connections to City infrastructure. Necessary connections would be along the property site frontage and would not require off-site utility extensions or improvements. These components have been evaluated for their potential to result in adverse environmental effects throughout this document. Mitigation Measures AQ-1 through AQ-5, BIO-1 through BIO-3, CR-1 through CR-3, GHG-1, and TR-1 and TR-2 would reduce potentially significant environmental impacts resulting from installation and establishment of new utility connections associated with air quality, biological resources, and cultural resources to a less- than-significant level. Therefore, potential environmental impacts associated with construction of utility connections would be less than significant with mitigation. b) The project would require an estimated 87.72 acre-feet of water per year during operation for the interior uses and landscape watering. Per the City’s Water and Wastewater Management Element, Policy A2.2.1, the City has four primary water supply sources, including Whale Rock Reservoir, Salinas Reservoir, Nacimiento Reservoir, and recycled water. Groundwater serves as a fifth supplemental source. The City’s diversification of water sources in the last several decades has allowed the City to maintain sufficient water supplies even following the driest years on record. The total water available for the City in the 2020 water year (October 1, 2019, to September 30, 2020) was 10,107 AFY, which included 215 AFY of recycled water. As this availability was adjusted following years of drought and updates to the City’s safe annual yield model, the availability is considered a reasonable long-term safe yield value for the purposes of this analysis. The City’s water demand for 2020 was 4,730 AF. Therefore, based on the project’s consistency with the General Plan and AASP, and the City’s current and projected water availability to serve the project, potential impacts associated with having sufficient water supplies during normal, dry, and multiple dry years would be less than significant. c) The project would be served by the City’s wastewater system and would include the installation of a new wastewater pipe to connect to existing City wastewater infrastructure along Broad Street. Estimated average dry weather flow would be 14,280 gallons per day. Thus, the project would result in an incremental increase in demand on the City’s WRRF and wastewater conveyance infrastructure. The project is consistent with the general level of growth anticipated in the City’s General Plan and AASP and would be required to pay standard development impact fees to offset the project’s incremental contribution to demand on the City’s WRRF. Therefore, impacts associated with the wastewater treatment provider’s capacity to serve the project’s wastewater needs would be less than significant. d) Based on the California Department of Resources Recycling and Recovery (CalRecycle), the project would result in the generation of approximately 408 pounds of solid waste per day (Table 9). Table 9. Estimated Project Solid Waste Generation Use Generation Rate Project Pounds Solid Waste Per Day Hotel 2 lbs/room/day 204 rooms 408 Total 408 Page 621 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 68 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Project construction and operational solid waste materials would likely be disposed of at the Cold Canyon Landfill. The Cold Canyon Landfill has approximately 14,500,000 cy of remaining capacity as of March 2020, with a maximum daily permitted intake capacity of 1,650 tons per day. Based on these capacities, the Cold Canyon Landfill is expected to remain operational though at least 2040. Therefore, potential impacts related to solid waste reduction goals and capacity would be less than significant. e) Background research for the Integrated Waste Management Act of 1989 (AB 939) shows that Californians dispose of roughly 2,500 pounds of waste per month. Over 90% of this waste goes to landfills, posing a threat to groundwater, air quality, and public health. To help reduce the waste stream generated by this project, consistent with the City’s COSE policies to coordinate waste reduction and recycling efforts (COSE 5.5.3), and the City’s Development Standards for Solid Waste Services, recycling facilities have been incorporated into the project design and a solid waste reduction plan for recycling discarded construction materials is a submittal requirement with the building permit application. Therefore, the project would comply with federal, state, and local management and reduction statutes and regulations related to solid waste and impacts would be less than significant. Mitigation Measures Implement Mitigation Measures AQ-1 through AQ-5, BIO-1 through BIO-3, CR-1 through CR-3, GHG-1, and TR-1 and TR-2. Conclusion With implementation of the identified mitigation measures, the project’s potential impacts associated with utilities and service systems would be less than significant. 20. WILDFIRE If located in or near state responsibility areas or lands classified as very high fire hazard severity zones, would the project: Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Substantially impair an adopted emergency response plan or emergency evacuation plan? 1, 24 ☐ ☐ ☒ ☐ b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? 1, 24, 52 ☐ ☐ ☒ ☐ c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? 1 ☐ ☐ ☒ ☐ d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? 1, 24 ☐ ☐ ☒ ☐ Evaluation Urban fire hazards result from the materials, size, and spacing of buildings, and from the materials, equipment, and activities they contain. Additional factors include access, available water volume and pressure, and response time for fire fighters. Based on the City Local Hazard Mitigation Plan, the risk of wildland fires is greatest near the City limits where development meets rural areas of combustible vegetation. Most of the community is within one mile of a designated High or Very High Fire Hazard Severity Zone, which indicates significant risk to wildland fire. Page 622 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 69 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 The City’s Safety Element identifies four policies to address the potential hazards associated with wildfire, including approving development only when adequate fire suppression services and facilities are available, classification of wildland fire hazard severity zones as prescribed by the California Department of Forestry and Fire Protection (CAL FIRE), prohibition of new subdivisions located within “Very High” wildland fire hazard severity zones, and continuation of enhancement of fire safety and construction codes for buildings. a) Implementation of the project would not result in a significant temporary or permanent impact to any adopted emergency response plans or emergency evacuation plans. No breaks in utility service would occur as a result of project implementation. During operation, the project would result in an increase in the number of employees in the AASP and, therefore, would result in an increase in the number of evacuees traveling on evacuation routes such as Broad Street (Highway 227) and U.S. 101. This increase would be marginal and would not result in substantial impairment of the applicable evacuation plans and/or routes; therefore, potential impacts would be less than significant. b) The project site is located in a developing area of the city. The project site is currently unimproved and requires routine mowing to prevent the growth of brush that could result in a fire hazard to adjacent properties. The project would not substantially change the existing topography of the project site. The project would result in the conversion of the existing undeveloped site into a fully developed site comprised of a hotel with surface parking and ornamental landscaping, which would reduce wildfire fuels on-site and may marginally reduce the potential for fire hazard in the immediate project vicinity. The project would be required to meet all applicable standards for fire prevention pursuant to the CBC and California Fire Code. For instance, the project would include the installation of a new fire hydrant and fire department connection as well as additional an additional water line. A fire sprinkler system would also be installed within the building. Therefore, the project would not exacerbate wildfire risks or expose project occupants to substantial pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire. Potential impacts would be less than significant. c) The project includes the installation of new water, emergency water, wastewater, stormwater, and energy extensions and connections to City infrastructure. These proposed infrastructure components would occur within an urbanized area and would be required to be installed in full compliance with applicable CBC and California Fire Code regulations. As discussed above, construction of this infrastructure would not result in substantial temporary or ongoing impacts on the environment. Therefore, potential impacts associated with exacerbation of fire risk or environmental impacts from installation of new infrastructure would be less than significant. d) The project site is generally flat and is not located near slopes or other areas subject to downstream flooding or landslides. The project does not include any design elements that would expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. Therefore, impacts would be less than significant. Mitigation Measures Mitigation measures are not required. Conclusion The project would not expose people or structures to new or exacerbated wildfire risks and would not require the development of new or expanded infrastructure or maintenance to reduce wildfire risks. Therefore, potential impacts associated with wildfire would be less than significant and mitigation measures are not required.

MANDATORY FINDINGS OF SIGNIFICANCE Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? 1, 2, 15, 16, 18, 25 ☐ ☒ ☐ ☐ The project is proposed in the developing AASP area of the city of San Luis Obispo and the project vicinity generally contains low habitat value for protected plant and animal species. Although the project site is unimproved, it is routinely mowed for fire protection, as required by the City. An ephemeral drainage and associated wetland habitat are located in the southwestern portion of the project area and would be avoided and protected by a 35-foot setback during project construction and operation. There is potential for special-status plant and animal species to occur on-site and mitigation measures have been incorporated to avoid and minimize potential impacts to these resources. Mitigation Measures BIO-1 and BIO-2 have been identified to avoid potential impacts to CRLF and VPFS should they occur within the ephemeral drainage and Mitigation Measure BIO-3 has been identified to avoid impacts to migratory nesting birds if construction activities occur during the typical nesting season. There are no known historic or prehistoric resources within the project site and Mitigation Measures CR-1 through CR-3 would reduce potential inadvertent discovery of these resources to less than significant. With implementation of identified mitigation measures and standard requirements, the project would not have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory. Potential impacts would be less than significant with mitigation. Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? N/A ☐ ☒ ☐ ☐ The project proposes the development of a hotel facility that is consistent with the AASP land use designation and the project site’s BP zoning. The AASP area would continue to be developed in accordance with the allowable development permitted in the AASP. When project impacts are considered in combination with other reasonably foreseeable impacts, the project’s potential cumulative impacts may be significant. Mitigation measures have been identified to reduce project-related impacts to a less-than- significant level. With the implementation of identified project-specific mitigation measures and payment of the City’s standard Development Impact Fees, the individual effects of the project would be marginal and cumulative effects of the project would not be cumulatively considerable. Therefore, potential impacts would be less than significant with mitigation. Page 624 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 71 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 Sources Potentially Significant Impact Less Than Significant with Mitigation Incorporated Less Than Significant Impact No Impact c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? N/A ☐ ☒ ☐ ☐ The project has the potential to result in significant impacts associated with air quality that, if left unmitigated, could result in substantial adverse effects on human beings. Standard mitigation measures have been identified to reduce these potential impacts to less than significant, including, but not limited to, standard idling restrictions, dust control measures, implementation of BMPs, and compliance with the CARB ATCM for Construction, Grading, Quarrying, and Surface Mining Operations to avoid impacts related to naturally occurring asbestos. With incorporation of identified project-specific mitigation and the payment of the City’s standard Development Impact Fees, potential environmental effects of the project would not directly or indirectly result in any substantial adverse effects on human beings. Therefore, potential impacts would be less than significant with mitigation. Page 625 of 1225 Issues, Discussion, and Supporting Information Sources ER # EID-0650-2020 CITY OF SAN LUIS OBISPO 72 INITIAL STUDY ENVIRONMENTAL CHECKLIST 2021 22. EARLIER ANALYSES Earlier analysis may be used where, pursuant to the tiering, program EIR, or other CEQA process, one or more effects have been adequately analyzed in an earlier EIR or Negative Declaration. Section 15063 (c) (3) (D). In this case a discussion should identify the following items: a) Earlier analysis used. Identify earlier analyses and state where they are available for review. The potential environmental effects of developing the project site with uses consistent with the BP zoning designation were previously evaluated in the Certified EIR for the AASP (SCH # 2000051062), which was certified by the City Council in September 2003. The Certified EIR is available on the city’s Community Development Department website at: <https://www.slocity.org/government/department-directory/community-development/documents-online/environmental- review-documents/-folder-719> b) Impacts adequately addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. In general, the Certified EIR adequately analyzed the environmental effects of developing the project site with uses permitted under the BP zoning designation. Section 15152 of the State CEQA Guidelines allows the Lead Agency to “tier” the environmental analysis for separate but related projects. Per Section 15152(b) of the State CEQA Guidelines, tiering “can eliminate repetitive discussions of the same issues and focus the later EIR or negative declaration on the actual issues ripe for decision at each level of environmental review. Tiering is appropriate when the sequence of analysis is from an EIR prepared for a general plan, policy, or program to an EIR or negative declaration for another plan, policy, or program of lesser scope, or to a site-specific EIR or negative declaration.” Per Section 15152(d) of the State CEQA Guidelines, tiering “shall be limited to situations where the project is consistent with the general plan and zoning of the city or county in which the project is located, except that a project requiring a rezone to achieve or maintain conformity with a general plan may be subject to tiering.” The preparation of a Tiered Initial Study/Mitigated Negative Declaration (IS/MND) for this project, which is consistent with the general plan and zoning, may have been appropriate, except that the existing baseline conditions, regulatory requirements and standard of analysis under CEQA, regulatory planning documents, and standards of mitigation have been improved considerably since the EIR was certified in September 2003. For example, in September 2003, CEQA did not require the evaluation of GHG emissions, energy consumption, VMT, tribal cultural resources, or wildfires. Many of the mitigation requirements listed in the AASP would need to be updated to meet more stringent and performance-oriented standards since the Certified EIR. Further, the existing setting and background conditions within the AASP have changed meaningfully since the AASP EIR was certified. As a result, this IS/MND incorporated information and findings from the Certified EIR where appropriate, but also evaluated the project’s potential environmental impacts at the project level, with project-specific mitigation measures. c) Mitigation measures. For effects that are “Less than Significant with Mitigation Incorporated,” describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions of the project. As discussed above, project-specific mitigation measures have been developed for the project to address a more stringent regulatory environment and more complex analysis methodology. All project-specific mitigation measures recommended in this IS/MND are consistent with and build upon the programmatic mitigation measures identified in the Certified EIR. 23. SOURCE REFERENCES 1.

Where feasible, the project shall incorporate low impact development (LID) features, including bioswales and permeable pavers, into the overall site design to retain runoff on site and avoid increased surface runoff into the drainage. 8. Where feasible, the project shall incorporate vegetated buffers, bioswales, and/or rain gardens on the drainage side of the development. 9. The use of landscaping plants that are known or have potential to become invasive shall be prohibited. BIO-3 If any ground disturbance will occur during the nesting bird season (February 1–September 15), prior to any ground- disturbing activity, a preconstruction nesting bird survey shall be conducted by a qualified biologist within 1 week prior to the start of activities. If nesting birds are located on or near the project site, they shall be avoided until they have successfully fledged, or the nest is no longer deemed active. A non-disturbance buffer of 50 feet will be implemented for non-listed, passerine species and a 250-foot buffer will be implemented for raptor species. No construction activities will be permitted within established nesting bird buffers until a qualified biologist has determined that the young have fledged or that proposed construction activities would not cause adverse impacts to the nest, adults, eggs, or young. If special-status avian species are identified, no work shall be conducted until an appropriate buffer is determined in consultation with the City and the California Department of Fish and Wildlife and/or U.S. Fish and Wildlife Service.

A summary of air quality and greenhouse gas (GHG) emissions modeling methodologies and results are provided below. Emissions modeling assumptions and output files are included as an appendix to this memorandum. AIR QUALITY AND GREENHOUSE GAS QUANTIFICATION METHODOLOGY Short-term Construction Short-term construction emissions associated with the proposed project were calculated using the California Emission Estimator Model (CalEEMod), version 2016.3.2, computer program. Emissions were quantified based on the default construction schedules, equipment use, and construction vehicle trips contained in the model. Off-site mobile-source emissions were adjusted to account for the SAFE vehicle rule. Emissions were quantified with and without implementation of fugitive dust control measures. For informational purposes, emissions were also quantified assuming the use of newer Tier 3 off-road construction equipment. Emissions associated with the application of architectural coatings assumes the use of low-VOC content (50 g/L, or less) architectural paints. To be conservative, estimated highest daily construction emissions assume that building construction, paving, and architectural coating application could potentially occur on the same day. Construction emissions modeling assumptions are summarized in Table 1. Table 1. Summary of Construction Modeling Assumptions CONSTRUCTION START DATE APRIL 2022 AMOUNT OF FILL TO BE IMPORTED/EXPORTED 8,900/10,000 CUBIC YARDS TOTAL SITE ACREAGE 5.04 ACRES TOTAL AREA TO BE PAVED 1.8 ACRES NUMBER OF PARKING SPACES 214 HOTEL BUILDING SQUARE FOOTAGE 125,200 NUMBER OF HOTEL GUEST ROOMS 204 Long-term Operations Long-term operational emissions were also calculated using the CalEEMod computer program. Modeling was conducted based on a daily vehicle trip-generation rate of 8.36 trips/room derived from the multi-modal traffic analysis prepared for this project (W-Trans 2020).1 An average trip distance of 8.3 miles was assumed, derived from the vehicle miles traveled 1 W-Trans. May 18, 2020. Multimodal Transportation Impact Study for the SLO Airport Hotels Project. Page 652 of 1225 612 12th Street, Suite 201 Paso Robles, CA 93446 805.226.2727 www.Ambient.Consulting P a g e | 2 (VMT) analysis prepared for the project (GHD 2020).2 Mobile-source emissions were adjusted to account for the SAFE vehicle rule and incorporation of proposed on-site pedestrian improvements. Mobile-source emissions were quantified with and without incorporation of the proposed Transportation Demand Management program, which would result in an estimated reduction of approximately 48 daily trips, which equates to an estimated trip reduction of 3%. The CalEEMod computer program is based on the 2016 building and energy-efficiency standards. These standards were most recently updated in 2018, which took effect January 2019. In comparison to the 2016 standards, these newer standards are projected to achieve additional reductions in energy use of approximately 30 percent for nonresidential buildings (CEC 2018).3 Anticipated reductions in energy use associated with the newer building code are predominantly associated with increases in energy-efficient lighting requirements. The use of water-efficient irrigation systems, water- efficient building fixtures, and energy-efficient appliances is also required by the California building code. Operational emissions were quantified to include reductions in energy and water use, consistent with current building standards. Utility intensity factors were adjusted to reflect compliance with the State’s renewable portfolio standards. GHG emissions associated with exterior water use was based on the project’s estimated MAWA of 746,972 gallons/year. GHG emissions associated with solid waste assumed a waste diversion rate of 50% for opening year 2023 conditions and 75% for future year 2030 conditions. All other assumptions were based on modelled defaults from CalEEMod. Estimated operational GHG emissions for year 2030 conditions, per service population (SP), were calculated based on an average of 25 employees for comparison to the City’s GHG threshold of significance. SUMMARY OF EMISSIONS MODELING RESULTS Short-Term Construction Construction generated emissions, without implementation of fugitive dust control measures, are summarized in Tables 1 through 3. As shown, estimated daily and quarterly construction emissions would not exceed SLOAPCD’s recommended thresholds of significance. Annual construction-generated GHG emissions are summarized in Table 4. Amortized construction-generated emissions, assuming a project life of 25 years, was also quantified in accordance with SLOAPCD-recommended guidance. Amortized construction emissions were included with total operational GHG emissions estimated for the project. Long-Term Operations Daily and annual operational emissions of criteria air pollutants and GHGs for opening year conditions are summarized in Tables 5 and 6, respectively. Annual operational emissions for future year 2030 conditions are summarized in Table 7. Operational emissions of criteria air pollutants would not exceed SLOAPCD’s recommended thresholds of significance. However, operational emissions for year 2030 would exceed the City’s GHG threshold of 0.7 MTCO2e/SP. Based on the modeling conducted for year 2030 operational conditions, the project would need to offset annual emissions of 1,367.9 MTCO2e to meet the City’s GHG threshold of 0.7 MTCO2e/SP. 2 GHD.

The proposed development includes two hotels and associated infrastructure and surface parking on an approximately five-acre lot. Terra Verde completed a desktop literature review and field survey for the site, which focused on the identification of sensitive biological resources that are present or have the potential to occur on or in the vicinity of the proposed project site. In addition, all plant and wildlife species and any other sensitive biological resources observed w hile on site were recorded. This report is intended to provide information about current site conditions in order to inform project planning and may be used to support the environmental review process. Existing Site Conditions The proposed project site is located immediately northwest of the San Luis Obispo County Regional Airport (Airport) at the corner of Broad Street (Highway 227) and Aero Drive in the City of San Luis Obispo, California. A majority of the survey area supports ruderal herbaceous vegetation with a cluster of non-native trees on the western edge of the survey area. The topography, soils and vegetation of the proposed project site and surrounding areas have been altered considerably through past land conversion, construction of the adjacent commercial developments, expansion of the Airport, and realignment of Aero Drive. A review of aerial imagery indicates that the property has been regularly mowed since the early 2000s (Google Earth 1994-2019). Topography on site is gently sloped toward a drainage that borders the southwestern edge of the survey area. Elevations on site range from approximately 157 to 173 Page 788 of 1225 2 feet (48 to 52 meters). Surrounding land uses include the Airport and associated infrastructure, commercial building parks, industrial businesses, rural and suburban residential areas and agriculture (e.g., vineyards). The unnamed drainage bordering the site flows generally northwest across the southwestern edge of the survey area (see Attachment A – Figure 2: Survey Results Map). The drainage enters the survey area through a culvert under Aero Drive and flows west along the edge of the survey area before making a 90-degree bend and continuing north-northwest for approximately 400 feet, where it flows into a 36-inch culvert in the northwest corner of the survey area. This drainage is ephemeral, conveying surface flows from the subject parcel and adjacent developments during periods of significant rainfall. Survey Methodology Prior to conducting field surveys, Terra Verde staff completed a background review of relevant literature pertaining to sensitive resources known to occur in the project vicinity, which included the following: • Aerial photographs of the project site (Google Earth 1998 – 2019) • USGS topographic map for the San Luis Obispo 7.5-minute quadrangle (National Geologic Map Database 2019) • Online Soil Survey for San Luis Obispo County, California (Natural Resources Conservation Service 2019) • Consortium of California Herbaria (CCH) online database of plant collections (CCH 2019) • California Natural Diversity Database (CNDDB) list of state and federally listed special - status species documented in the project vicinity (California Department of Fish and Wildlife [CDFW] 2019) • CNDDB map of special-status species that have been documented within a 5-mile radius of the project site (CDFW 2019) • California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants documented in the project vicinity (CNPS 2019) • United States Fish and Wildlife Service (USFWS) Critical Habitat Portal (USFWS 2019a) • USFWS National Wetland Inventory map (NWI) (USFWS 2019b) • David Wolff Environmental (DWE) San Luis Obispo County Airport Rental Car Facility Wetland Delineation & Jurisdictional Determination Report (DWE 2008a) • DWE San Luis Obispo County Airport Rental Car Facility 90 -day Comprehensive Wet and Dry Season Vernal Pool Branchiopod Survey Report (DWE 2008b) A list of regionally occurring special-status species was compiled based on records reported in the scientific database queries. This species list was used to inform the field survey effort. Terra Verde botanist Kristen Nelson and biologist Sara Snyder conducted a wetlands and waters delineation on October 03 (Terra Verde 2019) and a reconnaissance-level field survey of the entire project site on November 11, 2019. The survey area included the entire parcel and a visual scan of adjacent parcels (see Attachment A – Figure 1). During the survey, all botanical and Page 789 of 1225 3 wildlife species encountered via direct and indirect (e.g., scat, track, call) observation were recorded (see Attachment B – List of Botanical and Wildlife Species Observed). It is important to note that the survey was conducted outside the appropriate blooming period for the identification of most special-status botanical species with the potential to occur on site. Botanical species identifications and taxonomic nomenclature followed The Jepson Manual: Vascular Plants of California, 2nd edition (Baldwin et al. 2012), as well as taxonomic updates provided in the Jepson eFlora (Jepson Flora Project 2019). In addition, the field survey included a focused habitat assessment for vernal pool fairy shrimp (Branchinecta lynchi). Survey Results No special-status species were observed during the survey; however, the survey was not conducted during the appropriate blooming period of all regionally occurring special-status botanical species, when plants are most readily identifiable. Based on the results of the background literature review and observations made in the field, it was determined that up to three special-status botanical species, two special-status wildlife species, and migratory nesting birds and raptors have the potential to occur within the survey area. In addition to these resources, jurisdictional aquatic habitat was observed within the survey , including patches of in- channel wetland habitat that temporarily flood following rain events (see Attachment A – Figure 2). A detailed discussion of these resources is included below. Special-status Botanical Species Due to the high degree of land manipulation (e.g., placed fill, regular mowing etc.) within the project site, most of the site does not provide suitable habitat for special-status species. However, habitat within the jurisdictional drainage provides marginally suitable for special-status botanical species. As such, it was determined that low suitability habitat is present within the drainage and associated wetland habitat for the following species: • Congdon’s tarplant (Centromadia parryi subsp. congdonii), California Rare Plant Rank (CRPR) 1B.1 • Hoover’s button-celery (Eryngium aristulatum var. hooveri), CRPR 1B.1 • Adobe sanicle (Sanicula maritima), CRPR 1B.1 No special-status botanical species were documented during the survey. Low suitability habitat is present within the drainage and associated wetland habitat on site for Congdon’s tarplant, Hoover’s button-celery, and adobe sanicle. If present, Congdon’s tarplant would have been detectable at the time of the surveys completed by Terra Verde. As such, this species is not expected to occur on site. Though considered unlikely to occur due to degraded site conditions, Hoover’s button-celery and adobe sanicle may be present within the ephemeral drainage and associated wetland habitat, and would not have been detectable at the time of the surveys. If impacts are proposed to the drainage, appropriately timed surveys (i.e., April – May, and July) would be necessary prior to the start of work to confirm presence or absence of these species. Page 790 of 1225 4 Special-status Wildlife Species The potential for any special-status wildlife species to occur is considered low due to the disturbed nature of existing habitat with in the project area, annual disturbance associated with ongoing site maintenance activities, and the lack of continuity with areas of adjacent suitable habitat. Special-status wildlife species determined to have low potential to occur on site include: • Vernal pool fairy shrimp (Branchinecta lynchi), Federal Threatened • California red-legged frog (Rana draytonii), Federal Threatened, State Species of Special Concern (CSC) No special-status species were documented during the survey. Low suitability habitat is pr esent within the drainage and associated wetland habitat for California red -legged frog (CRLF). However, the nearest documented occurrence of CRLF is from 2006 approximately two miles from the project site. Further, the drainage does not provide suitable breeding habitat due to its flashy and ephemeral nature and lack of protective cover (e.g., willows, cattails, etc.), nor does it maintain contiguous natural connection to downstream aquatic habitat features, including the East Fork of San Luis Obispo Creek (i.e., isolated by surrounding development). Therefore, the likelihood of CRLF occurrence on site is considered low. In addition to the surveys completed by Terra Verde in 2019, wet and dry season protocol surveys were conducted for VPFS by David Wolff Environmental in 2007 (DWE 2008b). No VPFS were observed during the protocol wet season surveys. Two intact cysts and one broken cyst identified to the genus Branchinecta were documented by Dr. Marie A. Simovich in the soil samples collect for the protocol dry season surveys. It was Dr. Simovich’s opinion that habitat with viable populations of fairy shrimp contain cysts in much higher densities than that found in the samples from this drainage (DWE 2008b). In addition, the hydroperiod for ponded water within the drainage, based on current site conditions, is not expected to support a breeding population of VPFS. Based on the results of the 2007 protocol-level survey coupled with the 2019 assessment of current site conditions, the likelihood of VPFS occurrence on site is considered low. In addition, suitable habitat for nesting birds and raptors is present within the project area , particularly within the ornamental trees located in the northwest corner of the survey area. Migratory and special-status bird species are protected under the Migratory Bird Treaty Act and California Fish and Game Code. Hydrological Resources As described above, one ephemeral drainage crosses the southwest corner of the project site and continues onto the adjacent parcel, flowing northwest along the southwestern property boundary. At the time of the November 11 survey, ponded water was observed in a scoured pool immediately downstream of the Aero Drive culvert, which appeared to be runoff from landscape irrigation in the parking lot south of Aero Drive. The limits of federal and state jurisdiction associated with the drainage were assessed and mapped by Terra Verde during a waters and wetlands delineation on October 03, 2019 (Terra Verde 2019). Based on the presence of a defined bed and bank, including evidence of an ordinary high water mark (OHWM), i t was determined Page 791 of 1225 5 that the drainage likely falls under the jurisdiction of CDFW and the Regional Water Quality Control Board (RWQCB) as waters of the state, and the U.S. Army Corps of Engineers (Corps) as waters of the U.S. In addition, three in-stream, federal-defined wetlands were delineated in association with the subject drainage feature. Refer to the Waters and Wetlands Delineation Report for further details on the methods and findings of this effort (Terra Verde 2019). Recommendations The proposed project has been designed to avoid impacts to sensitive biological resources to the extent possible. Specifically, the development has been designed to avoid any direct impacts to areas of jurisdictional aquatic habitat and maintain a 35-foot setback from the outer limits of mapped jurisdiction associated with the drainage. The following measures are recommended to protect aquatic resources on site and minimize impacts to sensitive biological resources during and following construction: Measure 1: Protection of Hydrological Resources • The limits of all work areas shall be clearly delineated in the field during construction, and personnel informed of the need to avoid impacts to jurisdictional aquatic features (i.e., waters and wetlands). • For short-term, temporary stabilization, an erosion and sedimentation control plan shall be developed outlining Best Management Practices (BMPs), which shall be implemented to prevent erosion and sedimentation into the channel during construction. Acceptable stabilization methods include the use of weed -free, natural fiber (i.e., non-monofilament) fiber rolls, jute or coir netting, and/or other industry standards. BMPs shall be installed and maintained for the duration of the construction period. • The mapped limits jurisdictional areas shall be clearly shown on all sites plans and flagged prior to the start of any construction activity within 50 feet of the limits of the drainage. • All equipment and materials shall be stored a minimum of 35 feet from the edge of the drainage at the end of each working day, and secondary containment shall be used to prevent leaks and spills of potential contaminants from entering the drainage. • During construction, washing of concrete, paint, or equipment and refueling and maintenance of equipment shall occur only in designated areas a minimum of 35 feet from all drainages and aquatic features. Sandbags and/or sorbent pads shall be available to prevent any fluid releases from entering the drainage. • Construction equipment shall be inspected by the operator on a daily basis to ensure that equipment is in good working order and no fuel or lubricant leaks are present. • Incorporate low impact development (LID) features, including bioswales and permeable pavers, into the overall site design to retain runoff on site and avoid increased surface runoff into the drainage. • Where feasible, establish vegetated buffers, bioswales, and/or rain gardens on the creek-side of the development. Page 792 of 1225 6 • Avoid the use of landscaping plants that are known or have potential to be come invasive. Measure 3: Pre-construction Surveys for Nesting Birds If work is planned to occur between February 1 and September 15, a qualified biologist shall survey the area for nesting birds within one week prior to activity beginning on site. If nesting birds are located on or near the proposed project site, they shall be avoided until they have successfully fledged or the nest is no longer deemed active. A non-disturbance buffer of 50 feet will be placed around non-listed, passerine species, and a 250-foot buffer will be implemented for raptor species. All activity will remain outside of that buffer until a qualified biologist has determined that the young have fledged or that proposed construction activities would not cause adverse impacts to the nest, adults, eggs, or young. If special-status avian species are identified, no work will begin until an appropriate buffer is determined in consultation CDFW, and/or the USFWS. Conclusion Current development plans have been modified to avoid direct impacts to the drainage. Sensitive biological resources identified within the survey area include one jurisdictional drainage with three associated in-channel wetlands. Low suitability habitat is present within the drainage for California red-legged frog, Hoover’s button-celery, and adobe sanicle. Suitable habitat for nesting birds and raptors is present within the project site.

The project site is located 950 and 990 Aero Drive in the City of San Luis Obispo, San Luis Obispo County, California. Field surveys included a delineation of all waters and wetlands, as defined by the U.S. Army Corps of Engineers (Corps) and California Department of Fish and Wildlife (CDFW). The survey area encompassed the entire proposed project site and the immediately surrounding wetland and riparian habitats. This report has been developed by Terra Verde using current Corps guidance concern ing waters and wetlands delineations, CDFW guidance on delineating state-defined waters and wetlands, and 2019 field-based observations of site conditions within the project area. Information offered in this report is arranged to describe the delineation objectives, discuss pertinent regulatory contexts, explain the approach and methodology used by Terra Verde in this delineation, and provide a summary of technical results. This report is intended to provide details regarding aquatic resources on site and may be used to support permit application(s) to the Corps, CDFW, the Regional Water Quality and Control Board (RWQCB), and the City of San Luis Obispo for the proposed project Terra Verde delineated approximately 206 linear feet of federal-defined non-wetland waters and 0.13 acre of federal-defined wetlands. Further, Terra Verde delineated approximately 0.63 acre and 650 linear feet of CDFW-defined waters/wetlands. As necessary, this information may be used to support regulatory permits and/or project approvals from the Corps, CDFW, RWQCB, the City of San Luis Obispo and other resource agencies. The results of the delineation, as described in this report, are conditional upon a review and final jurisdictional determination by the Corp s Los Angeles District and regional office of CDFW.

This report summarizes the regulatory context, methods, and results of field surveys, which focused on the delineation of federal and state wetlands and waters, including those defined by Section 404 of the Clean Water Act (i.e., waters of the U.S.) and those that fall under the jurisdiction of the state of California, as defined by the California Fish and Game Code and the Porter Cologne Water Quality Control Act. The survey area included the entire proposed project area, as well as immediately adjacent wetland and riparian habitats (see Appendix A – Figure 2: Project Site and Survey Area Map). Preliminary site plans include the development of two new hotels and associated infrastructure on two undeveloped parcels totaling approximately 5 acres. The survey area encompassed the entirety of both parcels, focusing on one ephemeral drainage bordering the southwestern edge of the lot. This report has been developed following guidance from the Los Angeles District of the U.S. Army Corps of Engineers (Corps) and the U.S. Environmental Protection Agency (EPA) (EPA and Corps 2008) pertaining to wetland delineations, as well as California Department of Fish and Wildlife (CDFW) guidance on delineating state wetlands (Cowardin et al. 1979). The results of the delineation are based on field observations made on October 03, 2019 and are subject to final review and approval by the Corps and CDFW. As needed, this report may be used in acquiring regulatory permits and/or project approvals from the Corps, CDFW, the Regional Water Quality Control Board (RWQCB), and the City of San Luis Obispo (City). 1.1 Overview of Site Characteristics 1.1.1 Current and Historical Land Uses The proposed project site is located northeast of the San Luis Obispo County Regional Airport (Airport) at the southern limits of the City of San Luis Obispo. The site is also located within the Airport Overlay Zone (City 2019) which is zoned for business park development. It is surrounded by commercial developments, and public roadways. As such, the topography, soils, and vegetation of the proposed project site and surrounding areas have been altered considerably through past land conversion, construction of the adjacent commercial developments, expansion of the Airport, and realignment of Aero Drive. A review of historical aerial imagery indicates the Page 819 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 2 property has been regularly maintained (e.g., mowed) since the early 2000’s (Google Earth 1994- 2018). One unnamed drainage flows generally northwest across the southwestern edge of the survey area. Most of this drainage is located on the adjacent parcel. 1.1.2 Geomorphology and Landscape Context The project site is located within the San Luis Obispo Creek watershed, approximately two miles east of the East Fork of San Luis Obispo Creek. The San Luis Obispo Creek watershed is a coastal basin that originates in the southern Santa Lucia Range, approximately 2,500 feet above sea level (City/County 2003). Topography within the survey area is mostly flat to gently sloping, except at the southwest edge where it slopes steeply up to a developed lot. Elevations on site range from approximately 164 to 180 feet (50 to 55 meters). The geology of the project site consists of alluvial deposits, comprised primarily of clay and silty clay loam (U.S. Dept. of Ag. 2019). The project site is immediately bordered by Aero Drive to the south, a gravel parking lot to the west, existing commercial developments to the north and State Route 227 to the east . Highway 101 is located approximately 2.25 miles northwest of the project site. 1.1.3 Regional Climate The regional climate is Mediterranean, with mild, rainy winters and hot, dry summers. Heavy marine fog is often present in the late spring and early summer. Historical temperature and precipitation data were acquired from the Western Regional Climate Center (WRCC) for San Luis Obispo (Station No. 047851). According to available data, average annual precipitation for a 123- year (1893 to 2016) period for the project region is 22.40 inches (WRCC 2019). The average minimum and maximum temperatures calculated for the same time period are 41.3°F in January and 77°F in September (WRCC 2019). REGULATORY CONTEXTS 2.1 Rationale for the Determination of the Geographic Extent of Waters of the U.S. Delineation of the geographic extent of waters of the U.S., including wetlands, within the survey area was consistent with definitions provided in 33 CFR 328.3 (a) (1-8), 328.3 (b, c, and e), as well as routine procedures detailed in the U.S. Army Corps of Engineers Wetlands Delineation Manual (1987 Manual) (Corps 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region, Version 2.0 (2008 Arid West Regional Supplement) (Corps 2008). As defined in Section 404 of the CWA, the limits of Corps jurisdiction in non -tidal waters extends to the ordinary high water mark (OHWM) and includes all adjacent wetlands. The Page 820 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 3 following definitions are used by the Corps and EPA for the identification of wetlands and, as such, were used for the identification and delineation of wetlands at the project site . Waters of the U.S. are defined in Section 404 of the CWA as: "All waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; including all interstate waters including interstate wetlands, all other waters such as intrastate lakes, rivers, streams, mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce." Further, wetlands are considered waters of the U.S., and are identified as: "Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas." The Corps uses a three-parameter approach for identifying and delineating jurisdictional wetlands, where a wetland is defined as a feature associated with waters of the U.S., which is characterized by a dominance of hydrophytic vegetation, hydric soils, and wetland hydrology. 2.2 Rationale for the Determination of the Geographic Extent of Waters of the State CDFW follows the definition used by the U.S. Fish and Wildlife Service (USFWS) for the identification of single-criterion wetlands (Cowardin et al. 1979), which requires that only one of the three wetland criteria used by the Corps (i.e., hydrology, hydric soils, and hydrop hytic vegetation) be present in order to define a wetland. In addition, CDFW has jurisdiction over waters of the state, as defined under Section 1600 of the California Fish and Game Code. Specifically, CDFW uses the following definition for the identification of wetlands: “Wetlands are lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by shallow water. For the purposes of this classification, wetlands must have one or more of the following attributes: 1) at least periodically, the land supports predominantly Page 821 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 4 hydrophytes; 2) the substrate is predominantly undrained hydric soil; and 3) the substrate is non-soil and is saturated with water or covered by shallow water at some time during the growing season each year.” Based upon the above definitions, all wetlands determined to be under federal jurisdiction on site are also considered CDFW wetlands. 2.3 Consistency with SWANCC & Rapanos Guidance U.S. Supreme Court rulings in two prominent court cases addressing the extent of federal jurisdiction (i.e., Solid Waste Agency of Northern Cook County [SWANCC] v. Corps et al. [531 U.S. 159, 2001]; and Rapanos et ux., et al. v. United States [547 U.S. 715, 2006]) led to the development of federal guidance that requires careful examination and documentation of the physical location(s) of and hydrologic connections among waters and wetlands. To determine federal jurisdiction, emphasis is given to surface hydrologic connections between a wetland and “navigable waters” or “adjacency” of a wetland to traditionally navigable waters, and, thus, a “significant nexus” to interstate commerce. In addition, waters and wetland features can be determined to be under federal jurisdiction by the Corps or EPA if a significant nexus can be shown between the wetland feature in question and its contribution to the maintenance or restoration of the physical, chemical, or biological integrity of downstream waters that are traditionally navigable. Federal guidance for field delineation procedures that address the Rapanos decision has been offered by the EPA and the Corps in a joint memorandum issued on June 5, 2007 (EPA and Corps 2008). FIELD DELINEATION METHODS 3.1 Overview of Methodology Prior to conducting field surveys, a desktop review was completed, which included a review of current and historical aerial imagery (Google Earth 1994 - 2018), an online Soil Survey for the County of San Luis Obispo (U.S. Dept. of Ag. 2019), USGS topographic maps (USGS 2019), regional weather data (WRCC 2019), the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) (USFWS 2019), and preliminary site development plans. Terra Verde botanist Kristen Nelson and biologist Sara Snyder completed a formal wetland delineation on October 03, 2019 to identify and map the extent of jurisdictional waters and wetlands on site. Delineation methods followed routine procedures detailed in the 1987 Manual (Corps 1987) and the 2008 Arid West Regional Supplement (Corps 2008). In addition, wetlands Page 822 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 5 were classified based on hydrogeomorphic classes (e.g., riverine, slope, etc.) described by Brinson (1993) and Brinson et al. (1995). Field delineation of wetlands included an assessme nt of the hydrology, soil characteristics, and vegetation at eight sampling points (i.e., SP-01 through SP-08). Data was recorded using the Wetland Determination Data Form provided in the 2008 Arid West Regional Supplement (Corps 2008). At each sampling point, a soil test pit was excavated to a depth of at least 15 inches where possible, vegetation was characterized within a 5-foot radius of the excavated soil test pit, and indicators of wetland hydrology were documented (see Appendix B – Wetland Determination Data Forms). In order to delineate the edge of federal wetlands, sampling was conducted in areas that displayed apparent indicators of wetland hydrology and vegetation, as well as adjacent areas where no apparent wetland indicators were present, and transitional areas in between. As stated above, all wetlands determined to be under federal jurisdiction also fall under state jurisdiction. Further, any areas that were determined to meet at least one of the three wetland criteria (i.e., hydric soils, hydrophytic vegetation, wetland hydrology) were determined to be CDFW wetlands. The delineation of non-wetland waters included identifying the presence of field indicators for OHWM within the drainage. This assessment followed guidelines provided in A Field Guide to the Identification of the Ordinary High Water Mark in the Arid West Region of the Western United States (OHWM Manual) (Lichvar and McColley 2008). In addition, all waters and wetlands were assessed for hydrologic connectivity and/or adjacency to traditionally navigable waters and their tributaries. Connectivity was confirmed by determining that the drainage is hydrologically connected to the traditionally navigable waters of the Pacific Ocean via the East Fork of San Luis Obispo Creek, and the main stem of San Luis Obispo Creek (see Appendix A – Figure 3). The limits of federal jurisdiction and the northern limits of state jurisdiction were mapped in the field. The southern limits of state jurisdiction were not field mapped. Rather, they were approximated from aerial imagery, as the current project design will not impact the southern limits of the drainage feature. 3.1.1 Delineation of Wetlands Evidence of Wetland Hydrology Consistent with the 1987 Manual (Corps 1987), the 2008 Arid West Regional Supplement (Corps 2008), and current regulatory guidance (Corps 1992), wetland hydrology can be identified by evaluating a variety of direct and indirect indicators, including stream gauge or well data, flood predictions (i.e., FEMA maps), historic records pertaining to the study area, and visual observation of field indicators for the identification of jurisdictional waters and wetlands. Field indicators may include inundation and/or saturation, sediment deposition, drainage patterns, Page 823 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 6 hydric soil characteristics, watermarks, drift lines, presence of oxidized pores associated with living roots and rhizomes (i.e., rhizospheres), and water-stained leaves (Corps 1987). Wetland hydrology is present at a location if field observations indicate the area has a high probability of being periodically inundated or saturated to the soil surface for a sufficient duration during the growing season to develop anaerobic conditions in the surface soil environment (i.e., root zone) (Corps 1987). According to guidance provided in the 2008 Arid West Regional Supplement, if at least one primary indicator or at least two secondary indicators of hydrology are present at a sample point, the wetland hydrology criterion is met (Corps 2008). Observations of wetland hydrology were recorded at each sample point to document evidence of inundation or soil saturation. Several types of evidence were examined to determine whether wetland hydrology previously existed or currently exists. In addition, the type and frequency of site manipulation and anthropogenic disturbances were considered for their potential to impact or alter current and historical site hydrology. Identification of Hydric Soils The presence of hydric soils was assessed based on the criteria outlined in the 1987 Manual (Corps 1987) and the 2008 Arid West Regional Supplement (Corps 2008). Hydric soils are defined as soils “that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part” (U.S. Dept. of Ag. 1994). Determination of whether or not a soil is hydric is based on the fulfillment of at least one of four technical criteria (U.S. Dept. of Ag. 2002), which can be satisfied using a combination of published soils information and field indicators. Field indicators for determining whether a soil satisfies the hydric soil definition and the technical criteria for hydric soils are listed in Field Indicators of Hydric Soils in the United States (U.S. Dept. of Ag. 2006). Following the guidance provided in the above-referenced documents, the presence of hydric soils within the survey area was determined using a combination of direct field observation s and a review of available online resources, including the Soil Survey of San Luis Obispo County, Web Soil Survey (U.S. Dept. of Ag. 2019) and the USFWS NWI (USFWS 2019). In the field, soil test pits were excavated at each of eight sampling points to examine the upper 15 inches of the soil profile for hydric soil indicators. Specifically, a Munsell Soil Color Book (2000) was used to classify the colors of matrix soils and redoximorphic (redox) concentrations within the matrix. The 2017 Pocket Guide to Hydric Soil Indicators (Wetland Training Institute [WTI] 2017) was used to determine the texture of soils, and to assess the location, type, and extent of matrix soil colors and redox concentrations, to determine whether they qualified as hydric soils. Page 824 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 7 Dominance of Hydrophytic Vegetation On June 1, 2012, the 2012 National Wetland Plant List (NWPL) (Lichvar et al. 2012) replaced the USFWS 1988 National List of plant species that occur in wetlands for use under the CWA, Swamp Buster, and National Wetland Inventory programs. The NWPL and regional supplements have since been revised with updated plant listings. The Arid West 2016 Regional Wetland Plant List (2016 Regional List) (Lichvar et al. 2016) is the most current version available for use in the Arid West region, including coastal areas of California. The updated 2016 Regional List indicates the relative frequency that a species occurs in wetland habitats and is used to determine whether the hydrophytic vegetation parameter is met when conducting wetland delineations under the CWA. Species included on the 2016 Regional List are assigned one of the following wetland indicator statuses (Lichvar et al. 2012): • Obligate (OBL): plants that almost always occur in wetlands. • Facultative Wetland (FACW): plants that usually occur in wetlands but may occur in non- wetlands. • Facultative (FAC): plants that are equally likely to occur in wetlands and non -wetlands. • Facultative Upland (FACU): plants that usually occur in non-wetlands but may occur in wetlands. • Upland (UPL): plants that almost never occur in wetlands; plants not included on the list are considered UPL. Dominance of hydrophytic vegetation is determined by identifying all plant species within a 5- foot radius surrounding each soil excavation pit for herbaceous and shrub cover, and a 30-foot radius for tree and woody vine cover; documenting the absolute percent cover of each species within each stratum (i.e., herb, shrub, tree, and woody vine) for the sampling plot; and noting the indicator status for each (i.e., UPL, FACU, FAC, FACW, or OBL). Dominant species are then determined using the 50/20 rule, as recommended in the 2008 Arid West Regional Supplement (Corps 2008). Based on this method, dominant species are those species that individually or collectively constitute more than 50 percent of the total vegetative cover (i.e., relative cover) within each stratum, in addition to those species that individually constitute 20 percent or more of the relative cover within each vegetation stratum. Species identifications and taxonomic nomenclature followed the second edition of The Jepson Manual: Vascular Plants of California (Baldwin et al. 2012), as well as taxonomic updates provided in the Jepson eFlora (Jepson Flora Project 2019). According to both the Corps’ 1987 Manual (Corps 1987) and 2008 Arid West Regional Supplement (Corps 2008), the hydrophytic vegetation parameter for wetlands is met when, under normal Page 825 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 8 circumstances, more than 50 percent of the dominant species across all strata have an indicator status of OBL, FACW, or FAC. Connectivity/Adjacency As noted above, particular emphasis is given to surface hydrologic connectivity of wetlands to traditionally navigable waters, including adjacen cy of wetlands to jurisdictional waters. Connectivity of wetlands was established via field investigations, a review of aerial imagery, and an assessment of site-specific topography. 3.1.2 Delineation of Non-wetland Waters The OHWM Manual (Lichvar and McColley 2008) provides guidance on identifying field indicators of OHWM, including protocols for characterizing the overall system to determine the presence of waters of the U.S. Where apparent indicators of OHWM were observed, data was recorded using the Updated Datasheet for the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States (OHWM Data Sheet) (Curtis and Lichvar 2010). Completed data sheets are provided in Appendix C (Arid West Intermittent and Ephemeral Streams OHWM Datasheets). In addition, the lateral limits of waters of the State typically include the bed and bank and may extend to the limits of riparian vegetation if present. Cross-sectional Analysis Cross sectional analyses were conducted at three locations along the drainage where there was a clear change in the limits of either the OHWM or the top of bank. The physical and biological characteristics present at each cross section were documented on OHWM Data Sheets, including a sketch of the site topography at each cross section. Specifically, the floodplain units were described for each cross section through the vegetation cover, sediment texture, and hydrology indicators at that location. The limits of OHWM were determined based on the presence of hydrology indicators such as debris wracking, shelving, scour, and change in sediment texture/substrate. Connectivity/Adjacency Connectivity to traditionally navigable waters was assessed via field investigations, site topography, and a review of aerial imagery (Google Earth 1994 – 2018). RESULTS 4.1 Wetlands Determination Terra Verde completed a wetland delineation on October 03, 2019 and determined that federal wetlands are present within the drainage, which occur in disjunct patches connected by sections Page 826 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 9 of non-wetland waters of the U.S. (see Appendix A – Figure 5: Waters and Wetlands Delineation Map). Further, all areas meeting at least one of the federal wetland criteria were also ident ified as state wetlands. The results of the federal wetland delineation and sampling point data was documented on Wetland Determination Data Forms (Appendix B) and is detailed below. 4.1.1 Hydrology Within the drainage, field observations of wetland hydrology included primary and secondary indicators. Primary indicators observed included surface soil cracks (B6) and oxidized rhizospheres along living roots (C3). Secondary indicators observed included riverine water marks (B1), riverine sediment deposits (B2), riverine drift deposits (B3), drainage patterns (B10), saturation visible on aerial imagery (C9), and FAC-neutral test (D5). Wetland hydrology was determined to be present at SP-01 through SP-07, but not at SP-08 which was located on an adjacent flood plain outside the channel bottom (see Appendix A – Figure 5). 4.1.2 Soils According to the NRCS online soil survey of San Luis Obispo County, two soil units occur within the survey area (U.S. Dept. of Ag. 2019). These include: Unit 128 (Cropley clay, 2 to 9 percent slopes), and Unit 197 (Salinas silty clay loam, 0 to 2 percent slopes) (see Appendix A – Figure 4: Soil Units Map). Unit 128 is listed as partially hydric (U.S. Dept. of Ag. 2019). A summary of the dominant characteristics of these soil types is provided below. Soil Unit 128: Cropley clay, 2 to 9 percent slopes The parent material of this soil type is alluvium derived from calcareous shale. The drainage class of this unit is moderately well drained, and it is composed mostly of clay over sandy clay loam. This soil type tends to occur on alluvial fans and terraces below 2,340 feet. Soil Unit 197: Salinas silty clay loam, 0 to 2 percent slopes The parent material of this soil type is alluvium derived from sedimentary rock. The drainage class of this unit is well drained, and it is composed mostly of silty clay loam and very fine sandy loam. This soil type tends to occur on alluvial fans and flats, and flood plains. Soil test pits were excavated at each sampling point to classify the color and texture of the soil horizons down to at least 12 inches (except SP-01). Soil textures consisted of clay loam and clay at SP-03, silty loam and sand at SP-01, and clay at the remaining six sampling points (SP-02 and SP-04 through SP-08). Hydric soils were identified at SP-02, SP-03 and SP-05, all of which had a soil matrix of 10YR 2/1 with 2 to 5 percent reddish redox concentrations of 10YR 5/8 (SP-02) , 10YR 3/6 (SP-03) and 10YR 4/6 (SP-05) in the matrix and along pore linings (see Appendix D – Photos 4 through 6). SP-07 had a soil matrix of 10YR 2/1 in the upper 9 inches with 1 percent reddish redox concentrations and a mottled soil matrix of 80 percent 10YR 4/2 and 18 percent Page 827 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 10 10YR 3/2 below 9 inches with 2 percent reddish redox concentrations (see Appendix D – Photo 7). SP-01 was taken directly downstream of the culvert under Aero Drive and the upper 10 inches consisted of a mix of deposited sand/decomposed granite, landscaping soil , and woodchips that had been deposited from the upstream developed areas (see Appendix D – Photos 8). Below 10 inches was a layer of large rocks/riprap from armoring of the culvert outlet. A soil matrix color of 10YR 2/1 with no redox concentrations was documented at the remaining sampling points, SP- 04, SP-06 and SP-08 (see Appendix D – Photos 9 and 10). 4.1.3 Vegetation Greater than 50 percent relative cover of hydrophytic, herbaceous vegetation was documented at all eight sampling points. None of the sampling points supported tree, shrub, or woody vine cover. Dominant species included tall flatsedge (Cyperus eragrostis; FACW), common spikerush (Eleocharis marcrostachya; OBL), brown headed rush (Juncus phaeocephalus; FACW) and bristly ox-tongue (Helminthotheca echioides; FAC) at SP-01 through SP-07. Vegetation within the flood terrace surrounding SP-08 was dominated by salt grass (Distichlis spicata) and seaside barley (Hordeum marinum). 4.2 Non-Wetland Waters Determination The drainage is ephemeral, conveying water from the adjacent parking lot south of Aero Drive and across the western portion of the survey area before entering a 36-inch culvert in the northwest corner of the survey area. Within the survey area, the drainage displayed intermittent evidence of OHWM and a clearly defined bed and bank. Portions of the drainage are likely considered non-wetland waters of the U.S. based on the presence of a clearly defined OHWM identified by a distinct transition in vegetative cover, debris wracking, scour, and connectivity to traditionally navigable waters. Areas displaying evidence of OHWM are limited to two sections of the channel: 1) immediately downstream of the culvert under Aero Drive, and 2) in the section downstream of SP-04 until the central wetland. These areas are connected by areas of federal- defined wetlands and also some transitional areas where seasonal flows become less concentrated, fanning out into a wide floodplains and in -channel wetlands. These transitional areas did not display evidence of OHWM (see Figure 5). SUMMARY OF JURISDICTIONAL FINDINGS The jurisdictional waters identified within the survey area fall under the regulatory jurisdiction of the Corps, CDFW, and RWQCB. A summary of the type and extent of jurisdictional waters and wetlands is presented in Table 1 below. Page 828 of 1225 Aero Drive Hotel Project Waters and Wetlands Delineation Report San Luis Obispo, California 11 Table 1.

As such, no additional mapping or quantification of state wetlands has been completed as a part of delineation efforts. The geographic extent of waters of the U.S. (all area below the OHWM), totals approximately 206 linear feet and 0.009 acre within the survey area. A total of 0.13 acre of federal wetlands were mapped. The total area of proposed impact within jurisdiction al waters and wetlands will be determined based on final site plans. Section 404 of the CWA requires authorization from the Corps for the discharge of dredged or fill material into all waters of the U.S., including wetlands. The findings of this federal waters and wetlands delineation is subject to review and final concurrence by the Corps. The geographic extent of waters of the state (all area below top of bank or edge of riparian vegetation), including CDFW-defined wetlands, totals approximately 650 linear feet and 0.63 acres within the survey area. These areas may be regulated under the California Environmental Quality Act (CEQA), by CDFW under Sections 1600-1607 of the Fish and Game Code, and the RWQCB under Section 401 of the Clean Water Act and Section 13260(a) of the California Water Code.

Mitigation Results Summary Page 891 of 1225 1 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Executive Summary The proposed project consists of two hotels with a combined 218 rooms. The hotels would be located at 950 Aero Drive in the City of San Luis Obispo. Access to the site would be via a new driveway 300 feet west of the Broad Street/Aero Drive intersection. On a typical day the project would be expected to generate an average of 1,822 daily weekday trips, of which 102 would occur during the a.m. peak hour and 131 during the p.m. peak hour. The study area includes 13 existing intersections as well as the future intersection of Buckley Road/South Higuera Street, plus four study segments on Broad Street and Tank Farm Road. At each intersection, the service levels for vehicles, pedestrians, and bicyclists were reviewed as well as the project queuing. For the study roadways, all the previously aforementioned modes of travel were analyzed in addition to transit operations. Conditions during the morning and evening weekday peak period were analyzed for existing and cumulative scenarios. Under the Existing and Cumulative plus Project conditions, the project is expected to result in three project- specific adverse impacts at the following intersections and segments for the indicated mode of travel. Measures recommended to mitigate these impacts are also summarized in Table 1. Table 1 – Existing and Cumulative Plus Project Impacts and Recommended Mitigation Study Facility Mode Adverse Impact Mitigation Measure Existing Plus Project Tank Farm Rd/ Long St Auto The proposed project would increase the V/C on a stop-controlled approach operating unacceptably by more than 0.01 and a peak hour signal warrant is met. Improvements at intersection are included in City’s TIF and will be in place prior to the occupancy of the hotel. Payment towards the TIF would mitigate the adverse impact. Tank Farm Rd/ Santa Fe Rd Auto The proposed project would increase the V/C on a stop-controlled approach operating unacceptably by more than 0.01 and a peak hour signal warrant is met. While long-term improvements at the intersection would be mitigated through the payment of fees, to improve an adverse project impact under the existing conditions, the City should consider restriping the median on the west leg into an acceleration lane. Aerovista Ln/ Broad St Auto The proposed project would increase the V/C on a stop-controlled approach operating unacceptably by more than 0.01 and a peak hour signal warrant is met. To improve the project-specific impact under the existing conditions, the City should consider restricting left-turn maneuvers during the peak periods. Tank Farm Rd/ South Higuera St Auto The NB right-turn queue exceeds storage capacity and project would increase the length by more than one car length. While improvements are slated to be completed by other nearby projects, project specific interim improvements at the intersection would be signal timing optimization. Tank Farm Rd/ Broad St Auto The EB right-turn queue exceeds storage capacity and project would increase the length by more than one car length. To address the project-specific adverse impact, the project should pay towards the planned improvements specifically to convert the westbound right-turn lane to a shared through/right-turn lane. Optimize signal timing splits Page 892 of 1225 2 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Table 1 – Existing and Cumulative Plus Project Impacts and Recommended Mitigation Study Facility Mode Adverse Impact Mitigation Measure Broad St: Tank Farm Rd to Aero Dr (SB) Auto The proposed project would cause the facility to degrade to an unacceptable service level. At the intersection of Broad Street/Aero Drive, the project should install a southbound right-turn lane, southbound right-turn overlap, optimize splits. Cumulative Plus Project Broad St/ Capitolio Way Auto The proposed project would increase the V/C on a stop-controlled approach operating unacceptably by more than 0.01 and a peak hour signal warrant is met for a cumulatively adverse impact. Since this is a cumulatively considered impact and there would be a nearby signalized intersection for driver to reroute, no mitigation is proposed considering that the intersection operates acceptably overall. Broad St: Tank Farm Rd to Industrial Rd (NB) Ped The proposed project would reduce an already cumulatively deficient pedestrian score. A striped bicycle buffer would improve the pedestrian score. It is understood that this improvement is a part of the TIF. Notes: TIF = Traffic Impact Fee Outside of the operational analysis, based on the review of the collisions, a trend in broadside collisions at the intersection of Aerovista Place/Broad Street was identified between northbound and eastbound drivers. There is an existing two-way left-turn lane which, if being properly utilized, would reduce the number of these incidents. At the time of the site visit the striping was recently installed, and this improvement in visibility may contribute to better use of the lane. It is recommended that the City continue to monitor the collisions at this intersection for potential need of additional measures. There is currently a clear line of sight at the project driveway. To maintain sight lines, any landscaping along Aero Drive should be either low-lying vegetation or trees with canopies that are maintained and do not fall below seven feet above the elevation of the roadway. Additionally, parking should be restricted for 30 feet on either side of the driveway. It is understood that parking is currently allowed in the bike lanes on Aero Drive. It is recommended that the City revisit this practice to determine if this is consistent with the City’s policies on bicycle access. Page 893 of 1225 3 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Introduction This report presents an analysis of the potential traffic impacts that would be associated with development of a proposed Airport Hotels project to be located at 950 Aero Drive on the west corner of Broad Street and Aero Drive in the City of San Luis Obispo. The traffic study was completed in accordance with the criteria established by the City of San Luis Obispo and is consistent with standard traffic engineering techniques. Prelude The purpose of a traffic impact study is to provide City staff and policy makers with data they can use to make an informed decision regarding the potential traffic impacts of a proposed project, and any associated improvements that would be required to mitigate these impacts to a level of insignificance as defined by the City’s General Plan or other policies. Vehicular traffic impacts are typically evaluated by determining the number of new trips that the proposed use would be expected to generate, distributing these trips to the surrounding street system based on existing travel patterns or anticipated travel patterns specific to the proposed project, then analyzing the impact the new traffic would be expected to have on critical intersections or roadway segments. Impacts relative to access for pedestrians, bicyclists, and to transit are also addressed. Project Profile The proposed project entails two hotels totaling 218 rooms to be located at 950 Aero Drive in the City of San Luis Obispo. The hotels would be constructed in two phases. The first of the hotels to be constructed would have 100 guest rooms and include guest amenities like dining, meeting space, fitness room, breakfast area and bar. The second hotel would consist of 118 rooms and, in addition to the guest amenities listed above (except for the bar), would also include a pool. For both hotels, the guest amenities would be for patrons only and not open to the public. The hotels would be accessed from a single driveway on Aero Drive and would provide a total of 218 parking spaces. The project site is on the west corner of Broad Street and Aero Drive, as shown in Figure 1.

Buckley Road/South Higuera Street (Cumulative Intersection) Operating conditions during the a.m. and p.m. peak periods were evaluated to capture the highest potential impacts for the proposed project as well as the highest volumes on the local transportation network. The morning peak hour occurs between 7:00 and 9:00 a.m. and reflects conditions during the home to work or school commute, while the p.m. peak hour occurs between 4:00 and 6:00 p.m. and typically reflects the highest level of congestion during the homeward bound commute. Traffic turning movement counts for all but four of the intersections were obtained from the City. Those that were collected as part of this study are in Appendix A. Study Intersections Capitolio Way/Broad Street (SR 227) is a tee-intersection with stop-control on the east leg. There are no marked crosswalks. Industrial Way/Broad Street (SR 227) is a signalized intersection with protected left-turn phasing on each approach. Bike lanes are present along Broad Street, and there are crosswalks with pedestrian phasing on each leg. Los Osos Valley Road/US 101 South Ramps is a signalized four-legged intersection, with the off- and on-ramp for US 101 South on the north and south leg, respectively. The left-turn movement on westbound Los Osos Valley Road is a protected movement. There are crosswalks with pedestrian phasing on the on- and off-ramps. Los Osos Valley Road/US 101 North Ramps is a signalized tee intersection, with a protected left-turn movement on westbound Los Osos Valley Road and a right-turn overlap on eastbound Los Osos Valley Road. There are striped crosswalks on the US 101 Ramp leg as well as the east leg of the intersection served by an exclusive pedestrian phase where bicyclists or pedestrians can cross to any other corner. Tank Farm Road/South Higuera Street is a signalized intersection with protected left-turn phasing in the north and south direction and split phasing in the east and west direction and a right-turn overlap in the northbound Page 896 of 1225 6 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 direction.

Page 897 of 1225 7 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Collision History The collision history for the study area was reviewed to determine any trends or patterns that may indicate a safety issue. Collision rates were calculated based on records provided from the City for the city intersections as well as the collision records available from the California Highway Patrol as published in their Statewide Integrated Traffic Records System (SWITRS) reports. The five-year period reviewed was March 1, 2014 through February 28, 2019. As presented in Table 2, the calculated collision rates for the study intersections were compared to average collision rates for similar facilities statewide, as indicated in 2014 Collision Data on California State Highways, California Department of Transportation (Caltrans). Based on the available collision data, with the exception of Aerovista Place/Broad Street and Buckley Road/Edna Road, all of the study intersections have collision rates lower than the statewide average. The collision rate calculations are provided in Appendix B. Table 2 – Collision Rates at the Study Intersections Study Intersection Number of Collisions (2014-2019) Calculated Collision Rate (c/mve) Statewide Average Collision Rate (c/mve) 1. Capitolio Wy/Broad St (SR 227) 2 0.04 0.14 2. Industrial Wy/Broad St (SR 227 17 0.29 0.43 3. Los Osos Valley Rd/US 101 S Ramps 9 0.14 0.28 4. Los Osos Valley Rd/US 101 N Ramps 7 0.13 0.28 5.

Buckley Rd/Edna Rd (SR 227) 23 0.65 0.58 Note: c/mve = collisions per million vehicles entering; bold text = collision rate is higher than the statewide average The collisions records for the intersections of Aerovista Place/Broad Street and Buckley Road/Edna Road were reviewed for any trends. Of the six collisions at Aerovista Place/Broad Street, five were broadside collisions either due to right-of-way violations or improper turning. Of those five, four were eastbound drivers making a left-turn maneuver onto Broad Street. The other collision was a northbound driver making a left turn to Aerovista Place. While broadside collisions are common at two-way stop-controlled intersections, there is a two-way left-turn lane on Broad Street, which allows for a two-stage maneuver to enter the through street. Since four of the six collisions involved northbound through vehicles, this indicates that the drivers may not have been using the two-way left- turn lane. At the time of the site visit, Broad Street had been recently restriped, so the two-way left-turn lane was very visible but based on the available aerials, the striping was faded prior to that time. Though all-way stop controls are not currently warranted as there were no more than two crashes in a single twelve-month period, it is recommended that the City monitor the collision history for this intersection to determine if measures are warranted to potentially reduce the collision rate. Page 898 of 1225 8 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 At the intersection of Buckley Road/Edna Road, 20 of the 23 collisions were rear-end collisions; 17 of which had a primary collision factor of unsafe speeds. Nine of the rear-end collisions were in the southbound direction, six were in the northbound direction, and the remaining two were from the minor approaches. The intersection is known to experience long northbound queues in the morning peak period and southbound queues in the evening peak. There are currently plans to improve the intersection, as well as several to the north and south, by installing roundabouts designed for speeds of 30 miles per hour. With this improvement project, queues and the speed at which drivers travel along the road would be reduced. Based on a review of the collision records provided by the City in conjunction with the rates from the SWITRS database, the collision rates for the study segments are lower compared to statewide averages for similar facilities as shown in Table 3. Table 3 – Collision Rates for the Study Segments Study Roadway Segments Number of Collisions (2014-2019) Calculated Collision Rate (c/mvm) Statewide Average Collision Rate (c/mvm) 1. Broad St (SR 227): Orcutt Rd to Tank Farm Rd 48 0.99 1.67 2. Broad St (SR 227): Tank Farm Rd to City Limits 26 0.49 1.67 3. Tank Farm Rd: Broad St (SR 227) to S Higuera St 42 0.85 1.03 4. Tank Farm Rd: Broad St (SR 227) to Orcutt Rd 19 0.80 1.42 Note: c/mvm = collisions per million vehicles miles Alternative Modes Pedestrian Facilities Pedestrian facilities include sidewalks, crosswalks, pedestrian signal phases, curb ramps, curb extensions, and various streetscape amenities such as lighting, benches, etc. In general, a network of sidewalks, crosswalks, pedestrian signals, and curb ramps provide access for pedestrians in the study area, except for Tank Farm Road between Windmill Lane and the Mindbody entrance. In the vicinity of the project site, facilities exist where the properties have been developed. Broad Street (SR 227) between Orcutt Road and Tank Farm Road – There are discontinuous sidewalks on both sides of this section of Broad Street between Orcutt Road and Tank Farm Road. There are marked crosswalks at some intersecting streets with curb ramps present at most intersections. Broad Street (SR 227) between Tank Farm Road and City Limits – There are discontinuous sidewalks and intermittent streetlighting on both sides of this segment of Broad Street. There are crosswalks only at Tank Farm Road and Broad Street, though curb ramps are present at each intersection. Tank Farm Road between Broad Street (SR 227) and South Higuera Street – There are discontinuous sidewalks on both sides of this segment, though there is streetlighting. There are crosswalks present at the two major intersections along the segment. Tank Farm Road between Broad Street (SR 227) and Orcutt Road – There are sidewalks with streetlighting provided on both sides of this segment; the sidewalk on the north side of the segment ends at Righetti Ranch Road. Curb ramps are found at every intersection and there are crosswalks at most intersections. Page 899 of 1225 9 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Bicycle Facilities The Highway Design Manual, Caltrans, 2017, classifies bikeways into four categories: Class I Multi-Use Path – a completely separated right-of-way for the exclusive use of bicycles and pedestrians with cross flows of motorized traffic minimized. Class II Bike Lane – a striped and signed lane for one-way bike travel on a street or highway. Class III Bike Route – signing only for shared use with motor vehicles within the same travel lane on a street or highway. Class IV Bikeway – also known as a separated bikeway, a Class IV Bikeway is for the exclusive use of bicycles and includes a separation between the bikeway and the motor vehicle traffic lane. The separation may include, but is not limited to, grade separation, flexible posts, inflexible physical barriers, or on-street parking. In the project area, Class II bike lanes exist on Broad Street between Orcutt Road and the city limits as well as Tank Farm Road from South Higuera Street to Orcutt Street. According to the City of San Luis Obispo Bicycle Transportation Plan, 2013, there are planned Class II bicycle lanes along Tank Farm Road from Old Windmill Lane to Santa Fe Road. Bicyclists ride in the roadway and/or on sidewalks along all other streets within the project study area. Table 4 summarizes the existing and planned bicycle facilities in the project vicinity.

Route 1A operates Monday through Friday at approximately one- hour headways between 6:15 a.m. and 8:00 p.m. Saturday and Sunday service operates with approximately one- hour headways between 8:15 a.m. and 8:00 p.m. Two bicycles can be carried on most SLO Transit buses. Bike rack space is on a first come, first served basis. Additional bicycles are allowed on SLO Transit buses at the discretion of the driver. Dial-a-ride, also known as paratransit, or door-to-door service, is available for those who are unable to independently use the transit system due to a physical or mental disability. SLO Paratransit is designed to serve the needs of individuals with disabilities within San Luis Obispo and the greater San Luis Obispo area. Page 900 of 1225 10 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Capacity Analysis Intersection Level of Service Methodologies Level of Service (LOS) is used to rank traffic operation on various types of facilities based on traffic volumes and roadway capacity using a series of letter designations ranging from A to F. Generally, Level of Service A represents free flow conditions and Level of Service F represents forced flow or breakdown conditions. A unit of measure that indicates a level of delay generally accompanies the LOS designation. The study intersections were analyzed using methodologies published in the Highway Capacity Manual (HCM), Transportation Research Board, 2018. This source contains methodologies for various types of intersection control, all of which are related to a measurement of delay in average number of seconds per vehicle or pedestrian. Automobile Analysis The vehicular Levels of Service for the intersections with side street stop controls, or those which are unsignalized and have one or two approaches stop controlled, were analyzed using the “Two-Way Stop-Controlled” intersection capacity method from the HCM. This methodology determines a level of service for each minor turning movement by estimating the level of average delay in seconds per vehicle. Results are presented for individual movements together with the weighted overall average delay for the intersection. The study intersections that are currently controlled by a traffic signal, or may be in the future, were evaluated using the signalized methodology from the HCM. This methodology is based on factors including traffic volumes, green time for each movement, phasing, whether the signals are coordinated or not, truck traffic, and pedestrian activity. Average stopped delay per vehicle in seconds is used as the basis for evaluation in this LOS methodology. For purposes of this study, delays were calculated using signal timing from the City’s Synchro model. For the signalized intersections not included in the Synchro model, timing was obtained from the jurisdiction that maintains the intersection. The ranges of delay associated with the various levels of service are indicated in Table 5. Page 901 of 1225 11 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Table 5 – Automobile Intersection Level of Service Criteria LOS Two-Way Stop-Controlled Signalized Roundabout A Delay of 0 to 10 seconds. Gaps in traffic are readily available for drivers exiting the minor street. Delay of 0 to 10 seconds. Most vehicles arrive during the green phase, so do not stop at all. Delay of 0 to 10 seconds. B Delay of 10 to 15 seconds. Gaps in traffic are somewhat less readily available than with LOS A, but no queuing occurs on the minor street. Delay of 10 to 20 seconds. More vehicles stop than with LOS A, but many drivers still do not have to stop. Delay of 10 to 15 seconds. C Delay of 15 to 25 seconds. Acceptable gaps in traffic are less frequent, and drivers may approach while another vehicle is already waiting to exit the side street. Delay of 20 to 35 seconds. The number of vehicles stopping is significant, although many still pass through without stopping. Delay of 15 to 25 seconds. D Delay of 25 to 35 seconds. There are fewer acceptable gaps in traffic, and drivers may enter a queue of one or two vehicles on the side street. Delay of 35 to 55 seconds. The influence of congestion is noticeable, and most vehicles have to stop. Delay of 25 to 35 seconds. E Delay of 35 to 50 seconds. Few acceptable gaps in traffic are available, and longer queues may form on the side street. Delay of 55 to 80 seconds. Most, if not all, vehicles must stop, and drivers consider the delay excessive. Delay of 35 to 50 seconds. F Delay of more than 50 seconds or a V/C greater than one. Drivers may wait for long periods before there is an acceptable gap in traffic for exiting the side streets, creating long queues. Delay of more than 80 seconds or a V/C greater than one. Vehicles may wait through more than one cycle to clear the intersection. Delay of more than 50 seconds. Reference: Highway Capacity Manual, Transportation Research Board, 2018 Non-Automobile Analysis Similar to the automobile analysis methodology, the pedestrian and bicycle Levels of Service at the study intersections were based on the type of control, either for a signalized intersection or a two-way stop-controlled intersection. While the methodology for two-way stop-control is based on control delay, the methodology for signalized intersections is based on perceived service where a wide variety of factors, including the physical features of the facilities as well as the delay experienced, are considered in developing an operational “score”. The expectation for signalized intersections is that they are designed to carry higher traffic volumes and will result in greater pedestrian delay than an unsignalized intersection. Based on direction from the City, the intersections of US 101 Ramps with Los Osos Valley, Buckley Road/Edna Road (SR 227), and the future intersection of Buckley Road/South Higuera Street were not analyzed for alternative mode service levels. The ranges of perceived levels of service for pedestrians and cyclists are indicated in Table 6.

Usually no conflicting traffic. < 1.50 B Delay of 5 to 10 seconds. Occasionally some delay due to conflicting traffic. > 1.50 - 2.50 C Delay of 10 to 20 seconds. Delay noticeable to pedestrians, but not inconveniencing. > 2.50 - 3.50 D Delay of 20 to 30 seconds. Delay noticeable and irritating, increased likelihood of risk taking. > 3.50 - 4.50 E Delay of 30 to 45 seconds. Delay approaches tolerance level, risk-taking behavior likely. > 4.50 - 5.50 F Delay of more than 45 seconds. Delay exceed tolerance level, high likelihood of pedestrian risk taking > 5.50 Reference: Highway Capacity Manual, Transportation Research Board, 2018 Multimodal Roadways Segment Level of Service Methodology The roadway segment Level of Service methodology found in Chapter 18, "Urban Street Segments," of the Highway Capacity Manual is the basis of the automobile LOS analysis. This method does not address the capacity of a facility, but rather determines a Level of Service based the calculated percentage of the street’s base free-flow speed. In essence, congestion occurs as traffic volumes increase, and the overall travel speed is reduced due to increased delay. Therefore, the slower the speed, the lower that speed is as a percentage of free-flow speed, and the lower the Level of Service. The relationship between Level of Service and percentages of free-flow speed is presented in Table 7. Table 7 – Automobile Level of Service Criteria Level of Service Travel Speed as a Percentage of Base Free-Flow Speed (%) A >80 B >67-80 C >50-67 D >40-50 E >30-40 F ≤30 Reference: Highway Capacity Manual, Transportation Research Board, 2018 The pedestrian, bicycle, and transit roadway segment LOS methodologies from Chapter 18 were also applied. Similar to the methodology for pedestrian facilities at signalized intersections, the LOS is based on perceived service where a wide variety of factors, including the physical features of the facilities as well as the delay experienced, are considered in developing the operational scores. The relationship between the Level of Service and the scores for pedestrians, bicyclists, and transit is presented in Table 8.

Of the study intersections located on SR 227, only the intersection with Buckley Road is maintained by Caltrans and therefore their significance thresholds were applied in the analysis for this location only. Caltrans indicates that they endeavor to maintain operation at the transition from LOS C to LOS D. For queuing impacts, Caltrans considers a queueing impact if the project causes the 95th percentile queue to extend past the gore point on the freeway. City of San Luis Obispo With the exception of the SR 227/Buckley Road intersection, all of the study intersections are within the City’s jurisdiction. Based on the City’s Transportation Impact Study Guidelines, the following standards of significance were applied for automobile and non-auto modes of travel at intersections and along the study roadway segments. Intersection Operations Automobile At signalized intersections the City considers acceptable operating conditions to be LOS D or better. Based on City standards, the project is considered to have an adverse impact if: The project causes the intersection to degrade to LOSE or F or further degrade an unacceptable service level and increase the V/C ratio by 0.01 or more, where the V/C ratio reported is the highest V/C reported for the overall intersection. The project causes the 95th percentile turning movement queues to exceed the available turn pocket capacity or increase the queue where the capacity is already exceeded by one vehicle-length (25 feet) or more. The project’s proposed roadway geometry alterations cause an acceptably operating intersection to operate unacceptably or an intersection already operating unacceptably to deteriorate further. At unsignalized intersections the intersection is considered to be operating acceptably if the overall service level is LOS D or better. The proposed project is considered to have an adverse impact if: Page 904 of 1225 14 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 The project causes intersection service level, overall or for a movement, to decrease to an unacceptable LOS E or F or causes it to further degrade, the V/C is increased by 0.01 or more, and the Peak Hour Volume signal warrant is met. The project-added volume causes the 95th percentile turning movement queue to exceed the available turn pocket capacity or increase the already exceeded queue by one vehicles length. The proposed project’s geometry causes an intersection already operating unacceptably to degrade further or fall below the acceptable thresholds. Pedestrian and Bicycle At both unsignalized and signalized intersections, the acceptable service level is LOS D or better. The project is considered to have an adverse impact if: The project causes the service level to degrade to an unacceptable LOS E or F or causes it to further degrade. The proposed project’s geometry causes the minimum LOS standard to be exceeded or further degrades already exceeded LOS standards. Multimodal Segment Analysis For the multimodal segment analysis or for alternative modes at an intersection, as applicable, the minimum acceptable operation is LOS D or better and the project is considered to have an adverse impact if: For automobiles, the segment LOS degrades to LOS E or F or further degrades already exceeded service levels and the speed would decrease by 1 mph or more; For pedestrian facilities, the LOS degrades from acceptable service level to LOS E or F; For bicycle facilities, the LOS degrades from an acceptable LOS D or better to LOS E or F; For transit facilities, the segment’s service level degrades to LOS E or F from an acceptable service level; or, a segment with an already unacceptable service level would degrade further, based on the LOS or engineering judgement, as a result of the proposed project. Modal Priorities As part of the City’s standards, in addition to maintaining minimum levels of services, the City’s General Plan also prioritizes various modes of travel, depending on the type of facility, so that construction, expansion, or alteration of facilities for one mode does not degrade the service level of a higher-priority mode. The priorities based on the General Plan’s Circulation Element are summarized in Table 9.

This condition does not include project-generated traffic volumes. Volume data was collected while local schools were in session. Intersection Levels of Service Automobile Operations Analysis Under existing conditions, the study intersections are operating acceptably at LOS D or better overall during both peak hours, with the exception of the intersection of Edna Road/Buckley Road during the evening peak hour. Based on the field observations, the capacity of Edna Road, downstream of the intersection, results in southbound queuing. The existing traffic volumes are shown in Figure 2.

During the p.m. peak hour, the southbound right-turn movement at Los Osos Valley Road/US 101 South Ramps intersection has a V/C ratio of more than one; however, the intersection is operating at an acceptable LOS B overall. The southbound approach to the intersection of Tank Farm Road and Long Street operates with an unacceptable delay during the morning peak hour. During the p.m. peak hour, both stop-controlled approaches operate at LOS F, with the northbound approach operating with a V/C greater than 1.0. While the intersection of Tank Farm Road/Santa Fe Road operates acceptably overall, one or both of the minor approaches operate unacceptably during both peak hours. The eastbound approach to the intersection of Aerovista Place and Broad Street operates at an unacceptable delay during the evening peak hour, but the intersection as a whole operates at LOS A. During the p.m. peak hour, the intersection of Buckley Road and Edna Road operates at an unacceptable LOS F. Pedestrian Facility Analysis Under existing conditions all the intersections are operating acceptably except for the two-way stop-controlled intersections of Capitolio Way/Broad Street, Tank Farm Road/Long Street, Tank Farm Road/Santa Fe Road, Aerovista Place/Broad Street, and Airport Drive/Broad Street, where long delays are encountered by pedestrians crossing the through street. Since each of these crossings is near a signalized intersection with pedestrian crossings that operate acceptably, no deficiencies are reported. As noted previously, the intersections not within the City’s jurisdiction were not reviewed based on direction from the City. The results of the pedestrian analysis are summarized in Table 11 and the pedestrian Level of Service calculations are in Appendix D.

Given the limited service to the area, those segments that have one or more stops the transit facilities operate at unacceptable levels of service. Transit operations were not evaluated for segments that do not have a bus stop, including Broad Street between Aero Drive and Buckley Road, Tank Farm Road between South Higuera Street and Broad Street. The transit service levels for the roadways that were evaluated are summarized in Table 16.

Cumulative Conditions Segment volumes for the horizon year of 2040 were obtained from the City’s gravity demand model and translated to turning movement volumes at each of the study intersections using a combination of the “Furness” method and factoring, depending on how the model was configured at each intersection. The Furness method is an iterative process that employs existing turn movement data, existing link volumes and cumulative link volumes to project likely turning cumulative movement volumes at intersections. To be consistent with recently conducted traffic studies for other projects in the study area, the volumes were compared to those used in the Northwest Corner Tank Farm/Broad Mixed-Use Project Traffic Study, 2018, prepared by Central Coast Transportation Consulting. Where those volumes were higher, the higher numbers were used. Additionally, a minimum growth of 0.25 percent per year was applied. For the ramp intersections, very little to no growth is anticipated given the planned new Prado Road interchange to the north that would connect the eastern side of the City with the existing and proposed shopping centers. Additionally, the on- and off-ramp intersection is planned to be relocated from Los Osos Valley Road and onto Calle Joaquin. Since this improvement is not fully funded, the relocation of the southbound ramps was not assumed for the analysis. Per City staff, other infrastructure improvements in the study area expected to be complete by the Cumulative scenario horizon year include the signalization of the Long Street/Tank Farm Road intersection, the TIF or planned improvements at the intersections of Tank Farm Road/South Higuera Street and Tank Farm Road/Broad Street, the roundabouts at Tank farm Road/Santa Fe Road and Buckley Road/Broad street, the widening of Tank Farm Road, and extension of Buckley Road to South Higuera Street. This new intersection would be signalized and was included as a study intersection for the Cumulative scenarios only. Other planned improvements include the widening of Tank Farm Road, a roundabout at Santa Fe Road, and the extension of Santa Fe Road to the Prado Road extension. Because these projects have not been fully designed and the funding is not yet secure, the improvements were not assumed for the analysis. Cumulative volumes are shown in Figure 3.

The westbound approach of Capitola Way with Broad Street is expected to operate at LOS F during both peak hours. The V/C ratio for the northbound through movement during the p.m. peak hour at the intersection of Industrial Way/Broad Street intersection is greater than one but the intersection delay is still acceptable. During the p.m. peak hour, the southbound right-turn movement at Los Osos Valley Road/US 101 South Ramps intersection has a V/C ratio of more than one; however, the intersection is expected to operate at an acceptable LOS B overall. Page 916 of 1225 26 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 With the improvements at the intersection that are to be made as part of the other nearby projects, Tank Farm Road/South Higuera Street is projected to operate at an acceptable LOS though the the northbound right- turn movement would have a V/C of 1.05. The westbound through movement at the intersection of Tank Farm Road/Mindbody entrance has a projected V/C ratio of more than one during the evening peak hour. During the morning peak, the intersection of Tank Farm Road/Broad Street is anticipated to operate at LOS E and have movements with a V/C ratio of more than one. At the intersection of Aerovista Place and Broad Street, during the evening peak hour, the eastbound approach is expected to operate with an unacceptable delay, but the intersection as a whole would operate at LOS A. Pedestrian Facility Analysis Under the cumulative conditions, all the study intersections are expected to operate acceptably except for the two-way stop-controlled intersections. With signalization of the Long Street/Tank Farm Road intersection, acceptable pedestrian service levels at the intersection would be achieved. Since each of these locations are near a signalized crossing that is expected to operate acceptably, no deficiencies within the study area identified. As noted previously, the intersections not within the City’s jurisdiction were not reviewed based on direction from the City. The results of the pedestrian analysis are summarized in Table 18. Calculations are in Appendix D.

Since the bicycle intersection service level methodology does not consider bike boxes, it would be reasonable that the service level would be better than projected. Roadway Segment Levels of Service For each of the study roadway segments, the automobile, pedestrian, bicycle, and transit service levels were analyzed. Copies of the Level of Service calculations are provided in Appendix E.

Project Description The proposed project entails two hotels totaling 218 rooms to be located at 950 Aero Drive in the City of San Luis Obispo. The hotels would be constructed in two phases. The first of the hotels to be constructed would have 100 guest rooms and include guest amenities like dining, meeting space, fitness room, breakfast area and bar. The second hotel would consist of 118 rooms and, in addition to the guest amenities listed above (except for the bar), would also include a pool. For both hotels, the guest amenities would be for patrons only and not open to the public. The hotels would be accessed from a single driveway on Aero Drive and the project site would include a total of 218 parking spaces. The proposed project site plan is shown in Figure 4. Trip Generation The anticipated trip generation for the proposed project was estimated using standard rates published by the Institute of Transportation Engineers (ITE) in Trip Generation Manual, 10th Edition, 2017 for a Hotel (Land Use #310), as this description most closely matches the proposed project. No reduction is proposed for either “pass-by” trips or internal capture trips. Based on the nature of a hotel, the trips generated by the land use are specific to the location and would not be pulled from the existing traffic on nearby streets. Similarly, while there are facilities on the site that may keep guests on-site, like a gym, pool, or dining options, these types of facilities are common to hotels and therefore already incorporated into ITE’s trip generation rates. Based on application of these assumptions, the proposed two hotel locations are expected to generate an average of 1,822 trips per day, including 102 a.m. peak hour trips and 131 trips during the p.m. peak hour. These results are summarized in Table 24.

Under the cumulative conditions, it is expected that trip distributions would generally be the same as with the existing network, though some shifts would be expected to use the planned new street connections. The distribution assumptions and resulting trips are shown Table 25.

Intersection Operation Existing plus Project Conditions Automobile Operations Analysis Upon the addition of project-related traffic to the Existing volumes, the study intersections are expected to continue operating acceptably if currently operating at LOS D or better, and at unacceptable service levels if operating at LOS E or F under existing volumes without the project. Project traffic volumes added to the existing volumes are shown in Figure 7. These results are summarized in Table 26.

While this is counter-intuitive, this condition occurs when a project adds trips to movements that are currently underutilized or have delays that are below the intersection average, resulting in a better balance between approaches and lower overall average delay. The conclusion could incorrectly be drawn that the project actually improves operation based on this data alone; however, it is more appropriate to conclude that the project trips are expected to make use of excess capacity, so drivers will experience little, if any, change in conditions as a result of the project. The approaches to the intersection of Tank Farm Road and Long Street would continue to operate unacceptably overall; however, the northbound approach would deteriorate from LOS E to F, and based on the peak hour volumes, a signal would be warranted which is considered an impact based on the City’s standards. Because the intersection will be signalized as part of a new development in the area and that improvement would be complete by the time the proposed project is occupied, the intersection’s operation is expected to be acceptable at the time project trips are added. Page 929 of 1225 39 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Similarly, at the intersection of Tank Farm Road/Santa Fe Road, the V/C for the northbound side-street movement would increase by more than 0.01 and the approach is expected to continue to operate at LOS F with the project. While a roundabout is planned for the intersection, to address the project-considered impact in the short-term, the striped median should be restriped to provide an acceleration lane. With the addition of project-generated trips to the existing volumes, the V/C for the northbound through/right- turn lane at Tank Farm Road/Broad Street is expected to increase from 0.98 to 1.02. Because the intersection operates at LOS D overall, operation with the addition of project trips to the existing volumes would be considered acceptable. While the eastbound Aerovista Place approach to Broad Street is expected to operate at LOS E with and without the project, the signalized intersection of Aero Drive is nearby if the delay is intolerable and individual drivers wish to change their route to avoid this approach. However, as the project causes the V/C ratio to increase more than 0.01, the eastbound approach would continue to operate at LOS E, and the peak hour signal warrant is met, the project is considered to have an adverse impact. Since there is an easily accessible signalized intersection from this area for drivers to make an eastbound left turn on to Broad Street, it is recommended that left turns be restricted at this intersection during the peak hours. The intersection of Buckley Road/Edna Road operates at an unacceptable LOS F with and without the project; however, since the V/C ratio does not change as a result of adding project-generated traffic, the project is considered to have an acceptable impact based on the City’s standards. It should be noted that this intersection is part of a regional route that is known to operate at unacceptable service levels. As discussed in the State Route 227 Operation Study, Kimley-Horn, 2016, installation of roundabouts is recommended for this intersection, as well as Farmhouse Lane, Crescent Drive, and Los Ranchos. The study sets forth short to long-term goals for the implementation of the improvements, as well as the general cost estimates of the improvements. Finding – All of the study intersections, with the exception of the intersection of Buckley Road/Edna Road, are expected to operate acceptably overall with the addition of project traffic. While the addition of the project trips causes an increase in delay at the Buckley Road/Edna Road intersection, the project would be considered to have an acceptable impact since the highest V/C ratio at the intersection would not increase. While expected to operate acceptably overall, the two-way stop-controlled intersections of Tank Farm Road with Long Street and Santa Fe Road as well as Aerovista Place with Broad Street would be expected to experience an increase in the V/C of more than 0.01 for a movement that operates unacceptably, and a signal is warranted. Pedestrian Facility Analysis Under existing conditions with the addition of the project, the pedestrian facilities are expected to continue to operate at the same LOS as without the project. Given that the crossings that operate at unacceptable service levels are near locations that operate acceptably, no impact is identified. The results of the pedestrian analysis are summarized in Table 27.

Since the intersections that operate unacceptably are two-way Page 931 of 1225 41 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 stop-controlled intersections located near study intersections with signalized crossings and acceptable service, no impact is identified.

With the addition of the project, the queue length is not expected to increase by more than one vehicle length. It is furt her noted that the storage lane has additional stacking space as vehicles can queue into the two-way left-turn lane. For the Los Osos Valley Road/US 101 South ramps intersection, the eastbound right-turn (p.m. peak) and the southbound approach (both peaks) are projected to exceed the available storage. For the eastbound right-turn lane on Los Osos Valley Road, with the project added volumes, the queue length is expected to remain the same. For the off-ramp, the 95th percentile queue is expected to increase by six feet or less. Since that leg of the Page 934 of 1225 44 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 intersection is under the jurisdiction of Caltrans, the project is considered to result in a queuing impact if it extends past the gore point. The distance between the stop bar for the intersection and the gore point is about 800 feet so the queue is within the acceptable stacking length. At the intersection of Tank Farm Road and South Higuera Street, the queues are expected to exceed the available storage length in the northbound right-turn lane during the morning peak and in the southbound left-turn lane during both peaks; these queues would increase as a result of the project, though by less than 25 feet except under Existing plus Project a.m. peak hour conditions for the northbound right-turn. As part of the nearby projects of Avila Ranch and San Luis Ranch, the intersection would need to be improved with a second southbound left- turn lane and an extended northbound right-turn lane. With this improvement, the timing would be updated to reflect the additional capacity for that movement. However, since these improvements are not guaranteed to be implemented by the occupancy of the hotel, an interim improvement would be to optimize the signal timing. Under the existing conditions with the project and optimized signal timing, the northbound right-turn queue during the morning peak would be accommodated in the storage lane at an expected length of 50 feet. The northbound right-turn flare lane is expected to be exceeded at the intersection of Tank Farm Road/Santa Fe Road. While a roundabout is planned at this intersection in the long-term which would accommodate northbound queues, it is recommended that median on the west leg be restriped into an acceleration lane. At the intersection of Tank Farm Road/Broad Street, the eastbound right-turn, westbound left-turn, and southbound right-turn lane storages are expected to be exceeded. With the addition of the project trips, the eastbound right-turn lane queue would increase by more than one vehicle length and the addition of the project trips would cause the southbound right-turn storage lane to be exceeded. While there are currently plans to add a southbound left-turn lane, new northbound right-turn lane, add a second westbound through lane, and prepare time of day plans, the queueing impact for the eastbound right-turn and southbound right-turn is project-specific and would need to be mitigated. The project’s specific adverse queuing impact would be considered mitigated under the existing conditions if the westbound right-turn lane were converted to a shared through/right- movement lane and the signal timing splits optimized. With the additional capacity at the intersection and the optimized signal timing splits, while the eastbound right-turn lane queue would still exceed the available storage during the morning peak hour, the queue length with the addition of the project volumes and these mitigation improvements would increase by less than one car length. As such, the improvement would mitigate the project- specific adverse impact under the existing conditions. The mitigated queue lengths and resulting service level are summarized in Appendix G. At Buckley Road/Edna Road, queues in the eastbound right-turn lane and the northbound left-turn lane are expected to exceed the available storage. Since a roundabout is planned at this intersection, the queues would become a non-issue. Finding – The addition of the project trips to the study intersections under the existing conditions would cause the 95th percentile queues to exceed or exacerbate queues that exceed the available storage space at several intersections. Intersection Operations Recommendations Recommendation – To address the project-specific adverse impact under the existing conditions, the following actions are recommended: Tank Farm Road/South Higuera Street – Since the long-term improvements required to be built as part of other projects are not guaranteed to be completed before the hotel is occupied, an interim improvement would be to optimize the signal timing. Tank Farm Road/Santa Fe Road – to address the project specific adverse impact at the intersection, the City should consider restriping the existing median into an acceleration lane. Page 935 of 1225 45 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Tank Farm Road/Broad Street – To address the project-specific impact, the westbound right-turn lane should be converted to a shared through/right-turn lane. This improvement is part planned improvements at the intersection, but a fee that covers this specific change should be allocated to the project. Aerovista Place/Broad Street – To address the project specific adverse impact at the intersection, the City should consider restricting left-turn movements from the stop-controlled Aerovista Place approach during the peak periods. Cumulative plus Project Conditions Automobile Operations Analysis Upon the addition of project-related traffic to the Cumulative volumes, the study intersections are expected to operate at the same service levels as without the project, with exception of Tank Farm Road/South Higuera Street, Tank Farm Road/Broad Street, and Aero Drive/Broad Street. Consideration was given to the signal timing for the Aero Drive intersection and it was updated to reflect the increase in volumes on the minor approach; however, even with optimized splits, the project would cause the overall intersection delay to fall to an unacceptable Level of Service. These results are summarized in Table 26. Project traffic volumes added to the cumulative volumes are shown in Figure 8. The Cumulative plus Project operating conditions are summarized in Table 30.

While the project is considered to have an adverse cumulatively considered impact at the intersections of Capitolio Way/Broad Street and Broad Street/Aerovista Place because the minor approaches operate at unacceptable service levels, increase the V/C ratio by more than 0.01, and a peak hour signal warrant is met, the intersections operate acceptably overall. With the planned signalization of the Prado Road/Broad Street intersection nearby, drivers would likely reroute to that intersection to access Broad Street. Similarly, this would occur at the Aerovista Lane intersection though with the left-turn movement restricted during the peak periods, there would be no impact. Based on the City’s standards, the following intersections are considered to operate unacceptably, though no project impact was identified: The V/C ratio for the northbound through movement at the intersection of Industrial Way/Broad Street intersection is greater than one during the p.m. peak hour and with the addition of the project volumes the v/c increase by 0.02; however, the intersection operates acceptably overall based on delay. During the p.m. peak hour, the southbound right-turn movement at Los Osos Valley Road/US 101 South Ramps intersection has a V/C ratio of more than one; however, the intersection is expected to operate at an acceptable LOS B overall. With and without the project, the westbound through movement at the intersection of Tank Farm Road/Mindbody entrance has a v/c ratio of more than one during the evening peak hour. During the p.m. peak hour, the westbound movement is expected to operate with a V/C of more than one. Finding – The project would have a cumulatively considerable adverse vehicular intersection impact at the stop- controlled intersections of Broad Street with Capitolio Way and Aerovista Lane based on the City’s standards. Pedestrian Facility Analysis Under the cumulative scenario, with the addition of the project trips, the pedestrian facilities at the study intersections are expected to operate at the same service levels as without the project. The two-way stop- controlled intersections of Capitolio Way/Broad Street, Aerovista Place/Broad Street, and Airport Drive/Broad Street would operate at unacceptable service levels. Since each of these crossings have a signalized crossing that operated acceptably nearby, no deficiencies are reported. As noted previously, the intersections not within the City’s jurisdiction were not reviewed based on direction from the City. The results of the pedestrian analysis are summarized in Table 31.

Industrial Way/Broad Street during the p.m. peak hour for the northbound and southbound left-turn lanes. Los Osos valley Road and the US 101 South ramp intersection would have queues that exceed the available storage for the eastbound right-turn lane and the southbound approach. At most, these queues would be expected at 437 feet, within the available stacking area for the ramp. The southbound left-turn queue at the Tank Farm Road/South Higuera Street intersection, under the cumulative scenario, would extend into the two-way left-turn lane. Page 942 of 1225 52 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 While the increase in projected queues would be less than one car length at the intersection of Broad Street/Tank Farm Road, queues are expected to exceed the available storage for the eastbound right-turn, westbound left-turn, and southbound right-turn lanes. At the intersection of Buckley Road/South Higuera Street, the westbound southbound left-turn lanes would be expected to exceed the storage lanes with and without the proposed project. Finding – The addition of the project trips to the study intersections would increase the projected 95th percentile queues, several of which are projected to exceed the storage capacity. At these intersections, the proposed project would add less than one vehicle length, making the impact acceptable under the criteria applied. Intersection Operations Recommendations Recommendation – Since there were no cumulatively adverse project impacts given that several improvement projects in the area were assumed completed in the cumulative analysis, the project should pay its share of the City’s improvements assumed under the cumulative scenarios. Roadway Segment Operation Existing plus Project Conditions Automobile Operations Analysis Under Existing plus Project volumes, the study roadways segments that currently operate acceptably would continue to do so with the exception of southbound Broad Street between Tank Farm Road and Aero Drive, which would deteriorate to LOS E during the p.m. peak hour with the project. All other segments that currently operate at unacceptable service levels would continue to do so but the speed of the segment would decrease by one mile per hour or less. These results are summarized in Table 34.

Further south on the segment, Broad Street already operates at LOS F. Since this section of Broad Street and the intersection of Buckley Road operate as the choke point for the corridor, the speed and service level must decrease when trips are added. With the planned improvements on this section of Broad Street, including the roundabout at Buckley Road, the affected segments would be expected to have higher average speeds and the travel time through the network would be reduced by up to 74 percent as indicated in the State Route 227 Operation Study, prepared by Kimley-Horn, 2016. To mitigate the project-specific adverse impact under the existing conditions, a dedicated southbound right-turn lane with a programed right-turn overlap should be installed at the intersection with Aero Drive as part of the project’s off-site improvements. With this improvement, the service level for the segment would be LOS D. Mitigated results are summarized in Appendix G. Other segments that have an unacceptable percent BFFS, but the addition of the project trips does not cause a significant impact as it would not decrease the speed by more than one mph are: Page 944 of 1225 54 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Broad Street between Industrial Road to Tank Farm Road in both directions during the a.m. peak and only the northbound direction during the p.m. Northbound Broad Street between Tank Farm and Aero Drive during each peak period. Southbound Broad Street between Aero Drive and Buckley Road during the evening peak hour. Tank Farm Road between Mindbody entrance and Broad Street in the eastbound direction during both peak periods. Finding – With the addition of project trips to the study segment of southbound Broad Street between Tank Farm Road and Aero Drive, the service level would deteriorate from acceptable to unacceptable. With the planned SR 227 improvements, operation of this facility would improve. Recommendation – The proposed project should include installation of a dedicated southbound right-turn lane at the intersection of Broad Street/Aero Drive.

For some of the approaches, the addition of the project would degrade the LOS score further, specifically Broad Street between Industrial Road and Tank Farm Road in the northbound direction. Installing of a striped bicycle buffer would increase the distance between the vehicles and the pedestrians and result in an improved LOS Score; therefore, it is recommended that a striped buffer be installed between on Broad Street between Industrial Road and Capitolio Way. Mitigated results are summarized in Appendix G. Finding – With the addition of project trips to the study segments under the cumulative conditions, service levels for the pedestrian facilities are expected remain the same as without the project and with the exception of Broad Street between Orcutt Road and Tank Farm Road, there would be no adverse impact. Recommendation – A stiped bicycle buffer in the northbound direction on Broad Street between Industrial Road and Tank Farm should be considered to mitigate the pedestrian impact.

Page 951 of 1225 61 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Access and Circulation Site Access Access to the site would be via a new driveway located on the north side of Aero Drive, about 300 feet west of the signalized intersection with Broad Street. Sight Distance Sight distance along Aero Drive at the proposed project driveway location was evaluated based on sight distance criteria contained in the Highway Design Manual published by Caltrans. The recommended sight distance for minor street approaches that are a driveway are based on stopping sight distance which uses the approach travel speeds as the basis for determining the recommended sight distance. Based on a design speed of 25 mph, the minimum stopping sight distance needed is 150 feet. Sight distance at the proposed driveway was field reviewed as well as reviewed with available aerials. At the time of the site visit, sight lines were clear for more than 150 feet in both directions. However, to maintain a clear line of sight, any proposed landscaping along the Aero Drive frontage should be low-lying vegetation with a height of not more than three feet about the elevation of the roadway and any trees should have canopies trimmed to be no less than seven feet above the roadway elevation. Similarly, any signage or landmarks relating to the hotel project should be at an adequate setback so not to obstruct sight lines. Along the frontage of the site, there is currently a bike lane where airport patrons are permitted to park. With the project, parking should be restricted for 30 feet on either side of the driveway. While it is understood that the Airport has an agreement with the City for overflow parking to use the bike lanes, it is not a desirable condition for bicyclist and may conflict with State law. The City may want to revisit this issue and implement parking restrictions to keep the bike lane clear for cyclists. Page 952 of 1225 62 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 Conclusions and Recommendations Conclusions The proposed project is expected to generation an average of 1,822 daily trips; of which 102 would occur during the morning peak hour and 131 during the p.m. peak hour. Sight lines at the proposed driveway location are expected to be adequate. Parking is currently allowed in the bike lane on Aero Drive. Based on the collision history for the intersection of Aerovista Place/Broad Street, it was identified that drivers may not be using the two-way left-turn lane. Intersection Operations For automobile operations, under the existing conditions, all of the study intersection except for Buckley Road/Edna Road, are expected to operate acceptably overall with the addition of project traffic. There are project specific adverse impacts at the two-way stop-controlled intersections of Tank Farm Road/Long Street, Tank Farm Road/Santa Fe Road, Broad Street/Aerovista Way. Under the cumulative conditions, with the addition of the project trips, the proposed project is expected to have a cumulatively adverse automobile operation impacts at the intersections of Capitolio Way/Broad Street, Aerovista Place/Broad Street, and Aero Drive/Broad Street. For the pedestrian facilities under the existing and cumulative conditions, the service level at signalized intersections are expected to operate acceptably with the addition of the project trips. For the two-way stop- controlled intersections, the intersections would continue to operate a LOS F. Under the existing conditions and cumulative conditions which includes the planned improvements in the area, with the addition of the project, the bicycle facilities at intersection are expected to operate acceptably. Under the existing and cumulative conditions, with and without the proposed project, the transit service level is expected to operate at LOS F. The projected queuing at several of the study intersections is expected to exceed the available storage during the existing and cumulative scenarios, with and without the project. Under the existing conditions, with the addition of the project, there would be a project-specific adverse impact at the intersections of Tank Farm Road/South Higuera Street and Tank Farm Road/Broad Street. Under the cumulative conditions, the addition of the project trips to the study intersections would not increase the expected 95th percentile queue length by more than one vehicle, making the impact acceptable. Roadway Operations For automobile operations, under the existing conditions, with the addition of project trips to the study segment of southbound Broad Street between Tank Farm Road and Aero Drive, the service level would deteriorate from acceptable to unacceptable. Page 953 of 1225 63 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 The pedestrian segment facilities are expected to operate at the same service level as without the project under both the existing and cumulative scenarios; however, under the cumulative scenario, the already unacceptable pedestrian score decreases for an adverse impact on Broad Street north of Tank Farm Road For the bicycle roadway operations, the study segments are expected to operate acceptably with the addition of the project trips. Under the cumulative scenarios, with and without the project, the segment of Tank Farm Road between Broad Street and Orcutt Road would operate at unacceptable service levels, but the addition of project-generated traffic is considered to have an acceptable impact. Under the existing and cumulative scenarios, with and without the project would be expected to operate at unacceptable service levels. Recommendations It is recommended that the City monitor the reported collisions at the intersection of Aerovista Place/Broad Street. At the time of the site visit, the two-way left-turn lane on Broad Street was recently re-striped which potentially could have addressed a visibility issue with drivers. The City should revisit the practice of allowing parking in the bike lane on Aero Drive to determine if this is consistent with the City’s policies on bicycle access. In order to maintain sight lines at the proposed project driveway, any landscaping along the Aero Drive frontage should be low-lying vegetation with a height of not more than three feet about the elevation of the roadway and any trees should have canopies trimmed to be no less than seven feet above the roadway elevation. Any signage should be placed out of the line of sight. Parking should be restricted for 30 feet on either side of the driveway. Intersection Operations Under the Existing plus Project conditions, to address the project-specific impacts, the following actions are recommended: o The project’s specific adverse impact at the intersection of Tank Farm Road/Long Street could be addressed through payment of the City’s fees since the improvement would be completed as part of another project and would be complete prior to the occupation of the proposed hotel. o At the intersection of Tank Farm Road/Santa Fe Road, while there are plans to install a roundabout at the intersection that the project should ultimately pay fees towards, to address the project-specific adverse impact, the City could consider having project applicant pay to restripe the existing striped median on the west leg to provide an acceleration lane. o The project’s adverse impact at the intersection of Broad Street/Aerovista Way would be mitigated by restricting left-turn movements during the peak hours if the City concurs with this improvement. o Payment towards the City’s TIF would mitigate the project’s queuing impact at the intersection of Tank Farm Road/South Higuera Street. This improvement is expected to be completed before the occupancy of the proposed Airport Hotels. o The project-specific queuing impact at Tank Farm Road/Broad Street would be mitigated by converting the westbound right-turn lane to a shared through/right-turn lane. This improvement is part of several Page 954 of 1225 64 Multimodal Transportation Impact Study for the SLO Airport Hotels Project May 18, 2020 planned improvements at the intersection and the project should be conditioned to contribute toward the cost of this improvement. For the cumulatively considerable project impacts on automobile operations, the following actions are recommended: o While there is a cumulatively considerable impact at the intersection of Broad Street/Capitolio Way, under the cumulative scenario, there is planned to be a new signalized intersection nearby that drivers could reroute to in order to access broad Street. o Payment towards the Citywide TIF would include the project’s share of the cost of improvements to the intersections of Tank Farm Road/South Higuera Street and Tank Farm Road/Broad Street and mitigate the project’s impacts. Roadway Operations Participation in the San Luis Obispo County’s TIF Program for the SR 227 Corridor will mitigate impacts to the Broad Street (SR 227) segment Under Existing plus Project conditions, to mitigate the project-specific impact to automobile operations on southbound Broad Street between Tank Farm Road and Aero Drive, the project should include installation of a dedicated southbound right-turn lane with a right-turn overlap as part of its off-site improvements. To mitigate the project’s cumulative adverse impacts to pedestrians on northbound Broad Street between Tank Farm Road and Industrial Road, a striped bicycle buffer should be installed in the northbound direction between Industrial Road and Capitolio Way to increase the distance between pedestrians and vehicles.

Plnr/Engr. Project: Airport Hotel SB 743 From: Jake Hudson, Senior Trans. Eng/Pln GHD Ref/Job No.: 11219667 Subject: 950 Aerio Hotel VMT Analysis 1. Introduction A 218 room hotel is proposed on Aero Drive adjacent to the San Luis Obispo Regional airport. This technical memo provides an assessment of the project’s impact on regional Vehicle Miles of Travel under SB 743 and the new CEQA guidelines published by the California Office of Planning & Research as well the City’s adopted Multimodal Traffic Impact Study Guidelines as they relate to VMT Thresholds. California Senate Bill 743 was adopted in 2013 fundamentally changing transportation analysis under CEQA by replacing automobile congestion as expressed in delay and level of service with Vehicle Miles of Travel as the official CEQA metric for Transportation Impact Analysis. However, SB 743 specifically allowed public agencies to retain Automobile Delay & level of service as local policy thresholds. The City of San Luis Obispo adopted its CEQA Vehicle Miles of Travel (VMT) thresholds of significance follow California Office of Planning & Research guidance and updated its Traffic Impact Study Guidelines retaining level of service as local policy metric consistent with its general plan and impact fee programs in June of 2020. The results of this analysis shows a net increase in regional VMT as a result of the project which classifies as a significant impact under CEQA and the City’s Adopted Traffic Impact Study Guidelines. Page 1189 of 1225 Draft 950 Aerio VMT.docx 2 2. Methodology 2.1 Landuse Types & Significance Thresholds For the purposes of VMT analysis the City has adopted three categories for analysis: I. Residential: Any home based land use including single and multifamily projects. Projects under this category are evaluated using the percent difference in VMT per Capita of the project versus the Region. Projects are considered to have a significant impact if the VMT per capita is above the regional average less 15%. II. Work: Any project where the majority of trips are made by employees. Projects under this category are evaluated using the percent difference in VMT per employee of the project versus the Region. Projects are considered to have a significant impact if the VMT per capita is above the regional average less 15%. III. Retail & Other: Any project where the majority of trips are made by customers or patrons, this category also includes any type of non-residential and non-work based projects such as infrastructure projects or unique/unusual landuse types. Projects under this category are evaluated using the net change in VMT. Projects are considered to have a significant impact if they result in a net increase in regional VMT. For mixed use projects each individual landuse type within the project is evaluated independently, however, trip reduction characteristics of mixed use projects such as internal capture are accounted for. The proposed project classifies as a Retail / Other landuse because the primary trip making characteristics are non-residential and non-work based. Therefore, the project was evaluated based on its net change to regional VMT. 2.2 City Travel Demand Model As part of the City adoption of its VMT Thresholds various methodologies were considered including the City Travel Demand Model, SLOCOG Travel Demand Model, & Big Data Resources. The City ultimately adopted the use of its own travel demand model for the purposes of VMT analysis. A key criteria for any VMT calculation tool is that the tool must account for the full trip length of project trips. It was determined that the City’s travel demand model meets this criteria because the model boundaries extend regionally and the volume of trip production/attraction to the model boundaries are insignificant. Page 1190 of 1225 Draft 950 Aerio VMT.docx 3 To assess the project’s effect on net regional VMT the San Luis Obispo’s baseline Travel Demand Model was run with and without the proposed project landuse with its respective model traffic analysis zone (558) as shown to the right in Figure 1. Findings & Results The analysis shows that the project resulted in a minor increase in regional VMT as shown in the comparison table below. Although, minor the increase in net regional VMT is still considered a significant impact under both the California Office of Planning & Research as well as the City’s Adopted VMT Thresholds. Table 1: San Luis Obispo City Travel Demand Model VMT Results Area NET VMT Regional Baseline - Without Project 8,533,187 Regional Baseline - With Project 8,533,580 Net Change 393 % Change 0.005% Based on an assessment of trip lengths from the project’s traffic analysis zone within the model it’s estimated the average project trip length is approximately 8.3 miles. Therefore, approximately 48 project trips are contributing to the net increase in regional VMT. Figure 1 Project Model TAZ Buckley Tank Farm Page 1191 of 1225 Draft 950 Aerio VMT.docx 4 Although the average trip length is approximately 8.3 miles, modeled trip lengths ranged from 0 to 100 miles. As show in in table 1 to the right, trips in excess of 30 miles are projected to be infrequent. As shown in Figure 2, person trips within the immediate area of the project including the airport are estimated to account for approximately 15% to 20% of project traffic. The predominant travel pattern to and from the project is projected to be the City’s downtown core at 3 miles which accounts for approximately 30% to 35% of the project traffic.

The project can accomplish this reduction in three ways: 1. Modification of project description or construction of non-auto infrastructure that inherently reduces trip generation and VMT without the need for an on-going implementation effort and monitoring. However modification of the project description to the extent needed may not be feasible due to zoning limitations. Also construction of non-auto infrastructure solely funded by the project to the extent needed may not be feasible due to costs relative to the cost of the project itself. 2. The project can establish a peer to peer cap and trade or exchange with another property or development in process. This trade would result in lowering the significance threshold for the other property/development by 8.3 VMT and raising the significance threshold for this project by 8.3 VMT to achieve an overall no net increase in VMT. This would require an agreement between property owners and the modified thresholds to be recorded on the property deeds. This method would also not require an on-going implementation effort and monitoring. 3. The project can implement a programmatic trip reduction plan. CAPCOA’s “Quantifying Green House Gas Mitigation Measures” is currently one of the most widely used tool boxes of VMT mitigation measures, Attachment A to this report is a summary of the VMT reduction strategies reported by CAPCOA. Programmatic measures require active and on-going implementation by property occupants/owners in perpetuity as well as monitoring to ensure those measures are being implemented and are achieving the intended effect. Programmatic monitoring also imposes an on-going cost to the City. If a trip reduction plan is the adopted as the mitigation method; it’s recommended that the plan be recorded as a deed restriction or other similar means to ensure that future occupants/owners are aware of the requirement and are obligated to the on-going implementation of VMT reduction strategies. An on-going mitigation monitoring program should be included within the plan to ensure programs are being implemented by the occupants/owners and those programs are achieving their intent. The City should consider including requirements for the occupants/owners to fund costs associated with mitigation monitoring.

The VMT analysis found that the traffic generated by the proposed project would exceed the City’s adopted VMT thresholds by the equivalent of approximately 48 daily auto trips, therefore resulting in a significant transportation impact under CEQA. In order to reduce the impact to a less than significant level, Transportation Demand Management (TDM) measures are recommended to reduce the total VMT generated by the project. Per the Transportation Impact Study dated May 18, 2020, the project generated an average of 1,822 daily trips. A reduction of 48 daily trips represents a reduction of 3%. The following TDM measures are recommended in order to reduce the project auto traffic generation by at least 3%. TDM measures and anticipated trip reduction effectiveness are referenced from the California Air Pollution Control Officers Association (CAPCOA) “Quantifying Greenhouse Gas Mitigation Measures.” Evaluation of Potential TDM Strategies TDM Strategy Description of Proposed Measure CAPCOA Code Estimated Trip/VMT Reduction 1 Provide bicycle parking in non- residential projects Provide adequate, secure long-term bicycle parking for employees SDT-6 0.63% 2 Provide local shuttle service Provide free shuttle service from hotel to downtown SLO TST-6 2.00% 3 Provide Ride- Sharing Programs Participate in SLO Rideshare Back-N-Forth Club TRT-3 1.00% 4 Subsidize Transit Pass for employees Provide free or discounted transit passes to employees TRT-4 0.30% 5 Provide end-of- trip facilities Provide shower and changing room facilities for employees TRT-5 1.00% Page 1196 of 1225 Mitigation Summary Category Anticipated VMT Reduction Percentage Reduction in VMT Required to Shift Project to Below Threshold -3.00% VMT Reduction with TDM Measures 1 Provide bicycle parking in non-residential projects -0.63% 2 Provide local shuttle -2.00% 3 Provide Ride-Sharing Programs -1.00% 4 Subsidize Transit Pass for employees -0.30% 5 Provide end of trip facilities -1.00% Total 4.93% Finding: VMT reduction impact achieves the required 3% reduction in VMT.

RIGOR, ARCHITECT #C33672 February 19, 2020 Brian Leveille City of San Luis Obispo Community Development Department 919 Palm Street San Luis Obispo, CA 93401 Re: 790 Foothill - Automobile Trip Reduction Plan Dear Brian: This Trip Reduction Plan (TRP) outlines the measures that will be implemented in an effort to reduce the number of vehicle trips generated by employees and guests at the SLO Airport Hotel project. The proposed project’s location, directly adjacent to the airport and an Highwy 226 (Broad Street) will allow for multiple options beyond the single passenger vehicle Project Proposal The SLO Airport Hotel project includes 204 guest rooms. The focus of the TRP is the reduction of vehicle trips associated with travel to and from this project site. Trip Reduction Plan (TRP) measured proposed for this project: Reducing the negative environmental impact of our automobile traffic is a goal of this project and below is a list of automobile trip reduction measures that have been incorporated into the design. 1. Trip Reduction Coordinator A Trip Reduction Coordinator shall be appointed within the ownership/property management firm and act as the contact person for the City of San Luis Obispo and SLO Regional Rideshare. The coordinator shall be responsible for: Implementing an annual vehicle trip survey (can be administered through SLO Regional Rideshare.) Preparing an annual report, subject to the City’s review and approval, on the program’s effectiveness and recommendations for revisions if needed to improve the program’s effectiveness. Providing quarterly information (electronically or hard copy) regarding area transportation services and City and County transit passes. Coordinating employee transportation board meetings Coordinator will be responsible for establishing the Back ‘n’ Forth Club (for employees sponsored by Rideshare for the complex at a minimum of the Silver level. 2. Shuttle Service The hotel will offer a shuttle service to the airport terminal and downtown as requested by the guests. The hotel will also coordinate with local wine tours to encourage guests interested in wine tasting to utilize communal travel options rather than individual vehicles.

Community Transportation Board – A group of managers and employees, including the Trip Reduction Coordinator who meets to discuss and implement new ways to encourage employees and guests to participate in the community’s alternative transportation programs. 4. Shared Automobile – Onsite accommodations will be made available for a communal short-term rental car to enable guests to utilize a shared vehicle for short errands and other related needs. It is estimated that utilizing a car-sharing program alone will offset up to 10 required parking spaces. One company that offers this service is Zipcar. Information on their services can be found on their website https://www.zipcar.com/ or similar. 5. Bicycle Repair Station – A convenient station equipped with all of the tools necessary for employees to perform basic bike repairs and maintenance. 6. Showers and Locker Facilities The Hotel will include shower and locker facilities for employees that bike to work. 7. Shared Bicycles for Guests – The hotel will own and maintain bicylces available for guests to use to as an alternative to using vehicles. 8. Information Packets – Introductory packets, in either electronic or hardcopy form, for new employees with information pertaining to the car-sharing program, bicycle parking, bicycle repair station and a map showing the nearby bus stops. 9. Information Sharing – Management will distribute emails to keep the employees informed of activities. These emails will include up-to-date facts on car sharing availability, bicycle parking locations, alternative transportation programs and transit schedules. These emails will also include maps showing walking and bicycle routes to nearby retail, dining and service locations. These emails will be distributed to all residents. The Automobile Trip Reduction Program will be developed during the design phase of the project by the property owner. The responsibility for monitoring and reporting the progress of the program will be transferred to hotel management once the hotel is operational. Hotel management will be responsible to coordinating annual surveys, reporting to the city, and providing current and up to date program information to employees and guests. In coordination with RideShare, or a similar company, an annual survey of employees and guests will be conducted to gather information on travel patterns, program effectiveness, and resultant additional recommendations. In conjunction with the survey, an annual program report will be submitted to the City of San Luis Obispo Public Works Department Transportation Planner. The report will include a history of the project’s trip reduction efforts to date, the most recent resident survey results and any proposed modifications to the trip reduction plan. Thank you and please do not hesitate to let me know if you have any questions, comments or require additional information.
