Questions with similar themes have been combined in the responses below. The questions are bolded with staff’s responses shown in italics: Bob Jones Trail 1) Why does the project include a realigned Bob Jones Trail extension that runs alongside the LOVR Bypass between LOVR and South Higuera, instead of the previously proposed pathway alignment along San Luis Creek? The applicant has proposed a modified Bob Jones Trail alignment that runs parallel to the proposed LOVR Bypass Road primarily for the purposes of placing the trail in a more visible location to reduce potential for undesirable behaviors (i.e. illegal dumping, camping, etc.) and public safety concerns for trail users. The modified alignment would also place the path outside of the creek setback and riparian zone, reducing potential for environmental and flooding concerns. It should also be noted that, while the City allows construction of shared-use paths within creek setbacks with approval of a setback exception request, the City’s Active Transportation Plan recommends locating shared-use paths outside of creek setbacks. The alignment for this particular segment of the Bob Jones Trail was previously evaluated in a 2013 study, which recommended a preferred trail alignment that follows the creek corridor. The 2013 study recommended a Creekside alignment primarily to reduce impacts to the adjacent agricultural fields and farming operations. The 2013 study did note that if the future LOVR Bypass is advanced prior to the Bob Jones Trail construction, the “pathway would align with the Bypass and include separation from the roadway”. Item 8a – Broadstone Village Initiation Page 2 Ultimately, the project applicant and staff are supportive of (a) retaining the Bob Jones Trail alignment along the creek as previously approved, (b) aligning the trail parallel to the Bypass Road as proposed in the current Broadstone Village Project Plans, or (c) exploring a hybrid alternative that aligns the trail parallel to the creek along the development site to avoid driveway conflicts before aligning parallel to the Bypass Road south of the development to increase visibility. Attachment A (Bob Jones Trail Alignment Options), included in this correspondence, provides an illustrative map showing these options. Staff will be seeking input from the Council, Active Transportation Committee, and community to guide further development of the project circulation plans if Council supports initiating this planning effort. 2) How would the proposed relocation of the Bob Jones Trail from the approved Creekside location affect bicycle and pedestrian safety? The safety benefits of the modified alignment are greater public visibility of the trail and less potential for vagrancy and undesirable behaviors. The trade-off with the modified alignment proposal is that the trail would cross the two Broadstone Village site driveways south of LOVR, which creates a conflict point between vehicles, pedestrians and cyclists. The current design proposal assumes design strategies to minimize conflicts at these driveways, including a raised crosswalk, lighting, and high-visibility crosswalk markings. The benefits of the previously approved Bob Jones Trail alignment are that the trail would not cross the Broadstone Village site driveways by aligning along the creek. The trade-off would be less visibility of the trail and likely greater potential for public safety concerns. As noted in a previous response above, the applicant and staff are supportive of the previously approved Bob Jones Trail alignment following the creek, the modified alignment presented with this development proposal that parallels the LOVR Bypass Road, or a hybrid combining features of each alignment. Final designs for the trail would be based on Council direction, as well as additional input from the Active Transportation Committee and community, and the environmental review and analysis of any potential design constraints. 3) Can you provide more detail on why the Bob Jones Trail alignment is being proposed over the previously-approved alignment? How will this work with the approved design for the Higuera Complete Streets project? Do we need to rethink any elements of the three projects in relationship to one another? As noted in a previous response above, the modified Bob Jones Trail alignment was proposed to increase visibility of the trail for the safety/comfort of trail users, as well as to increase separation between the trail and creek riparian zone to reduce potential for environmental concerns. Staff and the applicant are supportive Item 8a – Broadstone Village Initiation Page 3 of retaining the previously approved alignment or the modified alignment proposal. The Higuera Complete Streets Project includes proposed intersection crossing improvements at the LOVR/Higuera intersection, including addition of a southbound bicycle signal phase. The Bob Jones Trail extension contemplated with this development proposal provides another opportunity for cyclists to cross LOVR but does not conflict with or eliminate the need for the crossing improvements proposed as part of the Higuera Complete Streets Project. 4) The applicant indicated three reasons for the BJT realignment: a. Alignment with county land and lack of county permission to build the BJT in the riparian zone. b. Distance from creek (environmental concerns). Previous approved alignment was too close to the creek. c. Safety, cleanliness In correspondence from members of the ATC and public, there was push back on two of these items. There is a belief that the county had already agreed to the riparian alignment and was not a part of the new proposed alignment. Can you speak to the involvement of the county up to this point and their take on both alignments? The reasons for the proposed modified Bob Jones Trail alignment are summarized in the previous responses above, as well as confirmation that the applicant and City staff would be supportive of the previously approved alignment or the modified alignment proposal, pending input from the Council, ATC and community. The City has not had direct conversations with the County regarding the modified trail alignment; however, the County has indicated that annexation of the Hayashi Property (APN 076-081-030) by the City would be required to support the proposed LOVR Bypass Road and Bob Jones Trail extension, which would allow the roadway and trail to be designed pursuant to City standards and policy direction. 5) Will the connection between the existing BJT and the new BJT be fully separated from LOVR? Rendering on page 290 of the staff report shows separation in the northern new development but seems to move out to LOVR on the city land. Final design details for the connection between the existing Bob Jones Trail terminus and the proposed extension south of LOVR will be refined pending input from the Council, Active Transportation Committee, and community. There are opportunities to provide this connection as a Class I bikeway (shared-use path) or via separate Class IV bikeway (protected bike lane) and sidewalks, or a combination of the two, on the north or south sides of LOVR, depending on whether the LOVR Bypass Road and new signalized intersection are recommended for advancement. Either way, the intent is to provide a facility that is physically separated from LOVR traffic. Item 8a – Broadstone Village Initiation Page 4 Environmental Review / Traffic Concerns 6) What environmental impacts would the project foreseeably have on the Hayashi Property? On traffic? On the neighborhoods? If Council authorizes the initiation of the project, environmental review will be completed in accordance with CEQA. This would include a range of technical studies to evaluate the potential environmental impacts of the project, and the environmental analysis would be considered by decisionmakers in the future. A formal transportation impact study has not yet been prepared for the development proposal to confirm potential traffic impacts and mitigation requirements. Based on findings of previous traffic studies for other large development projects in this vicinity, it is anticipated that focused analysis will be required for the LOVR/US 101 Interchange, Los Verdes Park driveways, LOVR/S. Higuera intersection and along the S. Higuera corridor, including future considerations both with and without the Prado Road/US 101 Interchange. Further, future traffic analysis scenarios will also assume the Higuera Complete Streets Project has been implemented. 7) The Applicant’s project description discusses water modeling that was completed for the project. What is this model and who did the modeling? The City contracts with Wallace Group Engineering to maintain and provide technical support for the City’s hydraulic model. This model allows for impacts to domestic water and fire water service to be evaluated for proposed projects. The water modeling for this specific project was completed by Wallace Group in December 2024. No issues were found to exist with this analysis. Any significant changes in the plans modeled may require additional analyses (Attachment C). 8) Members of the public have remarked that the County has significant flooding concerns about the bypass road. Is there a flooding analysis on their land that would garner that conclusion? A comprehensive study of the project’s impacts on the floodway will occur during the environmental review process if the project review moves forward. Future analysis will identify potential project-related impacts and recommended mitigation strategies for future consideration. 9) Agenda correspondence from the Applicant references future traffic studies. What happens if the future analysis shows untenable traffic flow impacts, can they build without providing any mitigations? A comprehensive transportation impact study has not yet been prepared for the development proposal. If the Council chooses to authorize further processing of the General Plan Amendment, Rezoning, and Annexation applications, it should be noted that authorization to initiate the project review does not require the Council to approve the final development proposal, as currently presented. If the Item 8a – Broadstone Village Initiation Page 5 project review progresses, there may be changes to the project scope based on new and more detailed information. The pending traffic impact study will identify potential project-related impacts and recommended mitigation strategies to guide future review of project entitlements by the Planning Commission and City Council. Ultimately, if there are traffic impacts that are unacceptable, the project could be denied, approved with conditions, or modified to address impacts. 10) The alternative for no annexations presented on pages 236-237 would result in the construction of more units, but would traffic analysis support the building of the project in that form? The developer has indicated that without the annexation, they would propose more units, however, the review process, including the environmental and traffic analysis, will inform what is actually proposed or allowed for approval and construction. A comprehensive transportation impact study has not yet been prepared for the development proposal with or without the potential annexation and LOVR Bypass Road. Based on preliminary due diligence analysis prepared to date, it is likely that without the proposed LOVR Bypass Road, there will be insufficient traffic from the development to warrant installation of a traffic signal at the new site driveways on LOVR. Further, due to proximity of the new site driveways to existing signalized intersections, left-turn movements exiting both the north and south Broadstone Village sites would likely need to be prohibited per City Access Management Standards. 11) Was residential development of this property included in the plans for the Prado Road Interchange? Was residential development of this property included in traffic engineering plans? What would the impact of this project be on traffic congestion? On the neighborhoods near the LOVR and South Higuera intersection? Transportation studies prepared previously for the Prado Road/US 101 Interchange Project as well as other large development proposals (San Luis Ranch, Avila Ranch, Froom Ranch, etc.) assumed future development of these properties, but with a lower level of density (approximately 160 dwelling units) compared to the current project proposal (409 total dwelling units). A detailed traffic impact study will be prepared for the current development proposal to identify potential off-site transportation impacts and mitigation recommendations, where appropriate. Based on the findings of other recent transportation impact studies, this traffic study will include increased focus on circulation within the southern portion of the City, including potential impacts on the Los Verdes Park driveways, LOVR corridor (including US 101 Interchange), Higuera Street corridor, and future traffic conditions with and without the planned Prado Road/US 101 Interchange in place. Item 8a – Broadstone Village Initiation Page 6 Annexation 12) Is the Hayashi Property (parcel proposed for annexation) currently protected by an Open Space/Conservation easement in the County? If yes, what entity is the easement holder? If no, is it zoned agriculture? When was its last agricultural use? Yes – There is an open space easement on a portion of the Hayashi Property as described and accepted by the Board of Supervisors in Resolution No. 81-485 (Attachment B). If annexation of this property is initiated, City staff would be working with County staff to have this easement conveyed from the County to the City as part of the review process. The property is in the County Agriculture land use category (AG) and is currently used for agricultural operations. 13) Was the annexation of this property included in the LUCE update or in any specific plan? If yes, which one/s? If no, why not? Was residential development of this property included in the City’s General Plan build out plans? If no, how would the additional units impact buildout? Annexation of the Hayashi Property is not specifically identified in the 2014 LUCE update. However, the property is eligible for annexation by the City since it is in the City’s Sphere of Influence (SOI). It should be noted that all residential development would occur on properties, currently within the existing City limits and urban reserve line (URL), and annexation is only intended to enable construction of the LOVR Bypass along with an extension of the Bob Jones Trail through the north portion of this property. The LOVR Bypass Road was discussed in the 2014 General Plan Circulation Element as a potential connection to be evaluated with any future planning efforts related to the Creekside Special Planning Area. Based on preliminary communications with the County of San Luis Obispo, the County is not interested in pursuing a roadway if the Hayashi Property remains within their jurisdiction. Therefore, the LOVR Bypass (and accompanying trail extension through the Hayashi Property) would only be achieved if the City pursues annexation and facilitates its construction as part of the development project. As detailed in the staff report, the 2020 Housing Element identified the North Site and South Sites (proposed for residential development) for possible rezoning to the R-3 zone, instead of the currently proposed R-4 zone for both sites. The request for the R-4 zone would result in approximately 55 additional density units, which have not been accounted for in the General Plan, and therefore would be studied for project impacts as part of the review process, if these applications are initiated. Item 8a – Broadstone Village Initiation Page 7 Growth Management 14) What would be the sprawl-inducing impact on our greenbelt? The residential development would be located on properties (i.e., North and South Sites) that are currently within the existing City limits and URL. Any improvements outside of the existing City limits and URL are specific to the LOVR Bypass and Bob Jones Trail extension, which would be possible features of the project, if the City Council authorizes processing of the Annexation application. The remaining majority of the Hayashi Property would be designated for agricultural use or as open space and would not induce sprawl outside of the URL. Note – If the annexation request is not supportable and this application is not authorized by the City Council for processing, then the applicant has indicated they would only pursue the residential development project on properties within City limits. In addition, growth inducing impacts of the project would be analyzed as part of the environmental review processes should the project move forward. 15) What other housing projects are currently entitled? How would this project affect the timing of other projects already in the works, i.e. the Madonna on LOVR property? How would it impact the City’s 1% Growth Management Ordinance that the City exceeded this year? There are over 1,000 housing units currently entitled but not yet constructed in the City. Many of these units are found in Avila Ranch, and the Orcutt Area and Airport Area Specific Plans. In addition, staff has received submittals seeking entitlements for development in the Froom Ranch Specific Plan area, which includes a total of 809 housing units. Traffic impact studies for large development proposals such as this one, include analysis of the proposed project under existing traffic conditions, as well as future near-term (5-10 year horizon) and cumulative (20 year horizon) conditions, which allows for evaluation of project impacts in conjunction with other planned and approved development projects, such as San Luis Ranch, Avila Ranch and the Froom Ranch Specific Plan. If the Broadstone project applications are authorized by Council for processing, staff’s subsequent review and evaluation would include an analysis of the impacts of these other entitled major planning projects. The phasing schedule of construction associated with the development of the Broadstone project would also be reviewed by staff for consistency with the City’s growth management limitations specified in Land Use Element Policy 1.11.2. Any deed-restricted affordable housing units included in the project would not be subject to the City’s growth management limitations. It is likely that the Broadstone project will take between 5-10 years to reach completion. At this point, the City will be in a new Housing Element cycle and possibly under updated General Plan Land Use and Circulation Elements. Item 8a – Broadstone Village Initiation Page 8 Project Design 16) Los Verdes Park single entry issues: Are they mandated under state law for fire safety to accept the additional entry point? There is no statewide mandate in California that explicitly requires an existing residential development to accept an additional entry point for fire and life safety. 17) Homes appear to be turned away from the riparian area. Is there a reason that they’re oriented this way? This initiation hearing is for early policy consideration. The plans provided by the applicant are preliminary and a full policy analysis of the design will occur should the project move forward. If directed by the Council, staff would work with the applicant if there is desire to incorporate the creek as an amenity in the project design. Funding 18) How much general fund money would be required to build the proposed bypass road, to extend water/sewer service to the area, provide public safety services, etc.? Can the City afford this expenditure of public funds, given the upcoming projected budget deficits? An estimate of general fund needed to support the project would require a fiscal impact study. Since a detailed project description is required to inform the fiscal impact study, and the project description would be affected by whether and how Council chooses to initiate these project applications, this study has not yet been completed. If Council directs staff to process these applications, a fiscal impact study could be required as part of the review process to inform Council’s final decision on the project. The fiscal impact study would evaluate ongoing costs associated with maintenance of new infrastructure, services, etc. Additionally, it should also be noted that staff is recommending that no general fund commitments be made to support the construction of the LOVR Bypass as described in the Council Agenda Report. Airport Land Use Commission 19) Would the Airport Land Use commission have jurisdiction over this property? Yes – All three (3) project sites are located entirely or mostly within the boundaries of the Airport Influence Area (AIA), specifically Safety Zone 6 (Traffic Pattern) of the AIA. Since the project includes various legislative applications, review by the Airport Land Use Commission for a consistency determination with applicable standards in the Airport Land Use Plan is required. Item 8a – Broadstone Village Initiation Page 9 Affordable Housing 20) How many affordable housing units should be considered beyond what is required if we are hoping to get closer to our goal of the additional 1200 needed in the next 3 years? Some correspondence mentioned a reduction in the number of required affordable units because these are designed for seniors. The affordable units that would be associated with this development, if there are any, are likely to benefit the City in the next housing element cycle, due to the timing of the project. On pages 246-247 of the staff report, staff has a provided an analysis of the number of units that would have been required of the project if it did not include a senior housing component (which has exempted it from the City’s inclusionary housing ordinance). This analysis is provided to facilitate a conversation about deed restricted units in the project, should the Council wish to provide direction.

The proposed residential development is split by Los Osos Valley Road (LOVR) into two sites– the north site is bound by LOVR to the south, Los Verdes Dr to the east, Chuparrosa Dr to the north, and San Luis Obispo Creek to the west, see Attachment A for the Utility Plan. The southern site is contained by LOVR to the north, Los Palos Dr. to the east, an agricultural field to the south, and San Luis Obispo Creek to the west. Figure 1 shows the proposed site and the City of San Luis Obispo (SLO) Edna Saddle water pressure zone in teal. Figure 1. Overview of the City Edna Saddle pressure zone and location of Broadstone Village. Broadstone Village Tank Farm Rd Madonna/Higuera PRV Edna Saddle Tank ATTACHMENT C December 13, 2024 Page 2 of 11 Site Description Both sites propose separate private domestic and fire water systems, each 8-inch diameter. On the north site, there will be two connections to the existing City of San Luis Obispo network: one connection to the existing 18-inch ductile iron pipe at LOVR, and the other to the existing 8-inch PVC at Los Verdes Drive. The southern site proposes a new 12” public water main from the 18-inch ductile iron pipe in LOVR through the frontage of the property. The 8-inch private domestic and fire water systems connect to the proposed 12-inch public water main at two locations to create a looped network. An 8-inch public main is proposed to connect the new 12” public water main to the existing City 8-inch main in Los Palos Drive. See Figure 2 in the following section. To obtain the requested data, Wallace Group used the hydraulic water model developed for the preparation of the December 2015 Final Water Master Plan (WMP). The model was updated and calibrated in October 2022. The model results presented below include the following: x To estimate the pressure losses at the 8-inch backflow prevention devices as shown on the utility plan, a loss curve from an 8-inch Wilkins Model 375 Reduced Pressure Principle Assembly was built into the model. x All proposed pipe is assumed to be PVC, with a Hazen-Williams C factor of 150 The following information is reflective of the water pressures and flows available at the proposed Broadstone Village: Water Distribution System Information Pressure Zone Edna Saddle Water Supply Edna Saddle Tank Madonna/Higuera PRV Tank Elevation during Average Day Demand (ADD) 345’ Tank Elevation during Maximum Day Demand (MDD) 339’ Tank Elevation during Peak Hour Demand (PHD) 333’ Madonna/Higuera PRV HGL 340’ Development Elevation Varies from 103’ to 114’ Required Fire Flow (FF) for high density residential per the WMP 2,000 gpm Note: required FF is without fire sprinklers, Fire Marshall has final say on required FF. Water Model Results Figure 2 shows the proposed (pink) and existing (teal) water mains as modeled in WaterCAD. Note that while each site will have parallel plumbing (separate fire and domestic systems), only the fire system was built into the model being that fire flow demands greatly surpass domestic demands; the fire system is the hydraulically critical one of the two. ATTACHMENT C December 13, 2024 Page 3 of 11 Figure 2. Overview of proposed water system. Elevations for each junction were assigned based on the “finish floor” elevations of the nearby pads per Attachment A, to represent the approximate pressure available at each unit. The assumed elevations are displayed in Figure 3 and Figure 4. 12” public water main ATTACHMENT C December 13, 2024 Page 4 of 11 Figure 3. Junction elevations for the north site. Figure 4. Junction elevations for the south site. ATTACHMENT C December 13, 2024 Page 5 of 11 Pressures During Average Day Demand (ADD) Pressures during ADD range from 91-103 psi. Figure 5. Pressures during ADD. ATTACHMENT C December 13, 2024 Page 6 of 11 Pressures During Max Day Demand (MDD) Pressures during MDD range from 89-101 psi. Figure 6. Pressures during MDD. ATTACHMENT C December 13, 2024 Page 7 of 11 Pressures during Peak Hour Demand (PHD) Pressures range from 83-96 psi Figure 7. Pressures during PHD. Available Fire Flow During MDD Available fire flow at each junction is shown in Figure 8 and Figure 9. These values represent the maximum fire flow that can be supplied at the junction without dropping pressure anywhere in the system below 20 psi. Note this does not represent the flow available out of any single hydrant, as it does not account for any losses through the hydrant valve, body, or orifice; these values represent the flow that the water mains can deliver without dropping below 20 psi. The lowest available fire flow of 5,200 gpm is at the north end of the north site; this significantly exceeds the highest requirement of 2,000 gpm for high density residential.

ATTACHMENT C December 13, 2024 Page 9 of 11 Residual Pressure at Fire Flow Needed – North Site Figure 10 and Figure 11 show the residual pressure at the total fire flow needed – 2,000 gpm. Note that these results reflect a single fire flow occurring at a time for each junction. Figure 10. Residual pressure at fire flow needed, north site. ATTACHMENT C December 13, 2024 Page 10 of 11 Residual Pressure at Fire Flow Needed – South Site Figure 11. Residual pressure at fire flow needed, south site. ATTACHMENT C December 13, 2024 Page 11 of 11 Discussion Static pressures for all scenarios are above 80 psi, therefore per California Plumbing Code individual pressure reducing valves (PRVs) will be required at each domestic service. Alternatively, a PRV can be installed at each connection to the City main on the domestic systems (immediately downstream the backflow prevention device) to create a lower pressure zone below 80 psi on the private systems. The proposed water system will have positive impacts on the City of SLO water system due to the new 12” City water main which creates an additional loop to the Edna Saddle pressure zone. Please let me know if you have any questions regarding the data provided. You can contact me at (805) 544-4011. Thank you.
