Item 6a. Authorization to Advertise Arterials 2023 Project (Spec. 1001001-1)
Item 6a Department: Public Works Cost Center: 5006 For Agenda of: 4/18/2023 Placement: Public Hearing Estimated Time: 20 minutes FROM: Matt Horn, Public Works Director Prepared By: Anthony Ramos, Engineer III SUBJECT: AUTHORIZATION TO ADVERTISE ARTERIALS 2023, SPECIFICATION NO. 2001001-1, SANTA BARBARA AVENUE (LEFF TO BROAD), MONTEREY STREET (SANTA ROSA TO CALIFORNIA), CALIFORNIA (SANTA ROSA TO CALIFORNIA), CALIFORNIA (MILL TO MONTEREY), MORRO STREET (MILL TO MONTEREY) RECOMMENDATION 1. Approve the project plans and specifications for Arterials 2023, Specification Number 2001001-1, for a total amount of $9,688,450; and 2. Authorize staff to advertise for bids; and 3. Authorize the City Manager to award the construction contract, including the Base Bid and any Additive Alternates, if the lowest responsible bid is within the publicly disclosed funding amount of $7,350,000; and 4. Authorize the City Engineer to approve Contract Change Orders up to the available project budget. REPORT-IN-BRIEF Following the City of San Luis Obispo’s Pavement Maintenance Plan (Pavement Plan), staff recommends advertisement of this pavement reconstruction project to provide maintenance, striping, and complete street improvements to the streets shown in Figure 1. Pavement maintenance projects often involve complete removal and replacement of roadway striping and pavement markings, which provides excellent opportunities to incorporate planned safety and complete street1 improvements as part of these larger roadway maintenance efforts. 1 A complete street is a transportation facility that is planned, designed, operated, and maintained to provide safe mobility for all users, including bicyclists, pedestrians, transit vehicles, trucks, and motorists, appropriate to the function and context of the facility. Page 355 of 829 Item 6a The Arterials 2023 Project will implement several complete street modifications envisioned for 1) Santa Barbara Ave., 2) Monterey St., 3) California Blvd., and 4) Orcutt Road in the Active Transportation Plan (“ATP”) to improve safety and mobility for all road users. These strategies include design elements intended to improve pedestrian crossing safety, increase separation between bicyclists and motor vehicle traffic, and calm traffic and reduce speeds through the city. The project is proposed to be funded in Fiscal Year 2023-24 and these funds are included in the 2023-25 Financial Plan that Council will consider adopting in June 2023. POLICY CONTEXT The project directly supports several key City plans, policies, and goals. The complete street components of the project support the recommendations of the ATP with the installation of protected bike lanes on Santa Barbara Avenue and extending the Morro Street (Bill Roalman) Neighborhood Greenway within the downtown, both projects identified as a Tier 1 (highest priority) project in the ATP. Monterey St ., California Blvd., and Orcutt Rd. also include complete street components that are consistent with the ATP for Tier 2 and 3 projects. The improvements also indirectly support the General Plan mode share targets and recommendations of the City’s Climate Action Plan for Community Recovery to improve active transportation and reduce reliance on single -occupant vehicles. The project also supports the current Sustainable Transportation and Climate Action Major City Goals. On May 17, 2022, Council approved a Purchasing Policy Update that requires Council approval for Public Projects with a value of $200,000 or more. DISCUSSION Background On April 14, 1998, the City Council adopted the City’s Pavement Plan. In 2009, the Pavement Plan was updated to provide additional emphasis on arterial streets , although maintenance was deferred several years due to budget constraints. A key element of the Pavement Plan is a rotating, and methodical approach, to ensure all areas of the city receive regular preventative and/or corrective paving maintenance. The City implements this rotation by performing maintenance in two neighborhood Pavement Areas in one year, and then focusing on arterial street work in the second year, thereby alternating between neighborhood areas and arterials biennially. Last June, the City Council received an update on the City’s Pavement Management Plan. It was noted that in order to achieve Council’s goals from the 2009 Pavement Management Plan, more emphasis must be placed on Arterials, Collectors, and Downtown pavement maintenance. At the time of the update, arterials, on average, had a lower Pavement Condition Index (“PCI”) than collector and local streets within the City. The report also mentioned that to keep up with the increasing cost to perform pavement maintenance and keep the road system in good condition, the City would need to spend approximately double the prior estimated budget for arterial paving projects. Page 356 of 829 Item 6a This past summer (2022), streets maintenance funding was used for local neighborhood streets in Pavement Areas 6, 7, and portions of Area 9 (Downtown Core), which included roadway sealing and striping enhancements. Improvements to both pedestrian and bicycle access in the form of curb ramps/bulb-outs, buffered bike lanes, the addition of two new neighborhood greenways, signal upgrades , and storm drain replacement were also completed. 2023 Arterials Project The 2023 Arterials Project is structured with a Base Bid and two Additive Alternatives, A and B, to maximize the scope of work within available funding. The project’s Base Bid includes pavement maintenance work, striping, curb ramps, storm drain and sewer infrastructure for the following streets, as visually shown in Figure 1: a. Santa Barbara Avenue (Leff to Broad) b. Monterey Street (Santa Rosa to California) c. California Boulevard (Mill to Monterey) d. Morro Street (Mill to Monterey) e. La Loma Court (Los Cerros to western terminus) The project’s Additive Alternatives A and B include pavement maintenance, striping, curb ramps, and storm drain infrastructure to the following streets, respectively: a. Orcutt Road (Laurel to Johnson) b. Palm Street (Santa Rosa to Pepper) Page 357 of 829 Item 6a Figure 1: Project Vicinity Map It should also be noted that slurry seal on Johnson Avenue from Buchon Street to Laurel Lane was originally planned for inclusion in the Arterials 2023 paving project but has since been recommended for deferral. In preparation for the future slurry seal of Johnson, base repairs will be performed as a part of this paving project. See further discussion on this below for justification. ORCUTT Legend Base Bid Additive Alternative “A” Additive Alternative “B” Page 358 of 829 Item 6a Pavement Reconstruction and Maintenance Pavement analysis was completed (October 2022) which confirmed that the following streets, Santa Barbara, California, La Loma, and Orcutt, are all structurally deficient to carry current and projected traffic loading. Many of these pavement areas have moderate to severe cracking, rutting in wheel-paths, and potholes, and are near the end of their useful life. Full-depth Hot Mix Asphalt (HMA) reconstruction is recommended for Santa Barbara, California, La Loma, and Orcutt to bring the pavement to new condition and eliminate the need for more frequent small maintenance repairs that would be ineffective in the long term. This selected method of reconstruction is the most cost -effective, with an expected service life of 15-20 years. A 22’ wide section of concrete pavement exists below Orcutt Rd. For this section, the existing asphalt layer will be removed and replaced to create a smooth driving surface along with the Full-depth HMA reconstruction method for the portions of road the do not have the concrete pavement underneath. Monterey, Morro, and Palm are concrete streets, with Monterey and Morro having an asphalt overlay. The pavement structure is acceptable, as the concrete provides a solid base layer; however, the asphalt overlay on Monterey and a portion of Morro from mid- block (Palm to Monterey) to Higuera is deteriorated and failing due to age and wear. The asphalt overlay will be removed and replaced to create a new smooth surface for all users of the roadway. On Palm, there is not currently an asphalt overlay from Santa Rosa to Pepper. The existing concrete pavement is in acceptable condition to provide a solid base but will be milled to apply an asphalt overlay to create a new smooth surface. In addition to roadway maintenance, this project will install Americans with Disabilities Act (ADA) compliant curb ramps on various intersections of California, Monterey, Santa Barbara, and Palm. Recently, the City has installed 40 curb ramps with the Area 6 & 7 Curb Ramp Project and has plans to install 46 more curb ramps with the recently awarded North Chorro Greenway project as well as up to 21 curb ramps with The CDBG Curb Ramps 2022 Project. , This project also plans to replace roadway striping and pavement markings, which provides an excellent opportunity to implement several complete street improvements as identified in the City’s Traffic Safety Report, Active Transportation Plan and Downtown Concept Plan. These complete street improvements, which are described in more detail in the section below, will support the City’s 2021 -23 Major City Goal of Climate Action, Open Space and Sustainable Transportation, as well as the City’s mode shift targets and Vision Zero goal to eliminate traffic-related fatalities and severe injuries citywide. This project will also incorporate replacement of aging sewer and storm drain infrastructures within the limits of the paving work. To reduce the need for preventative maintenance and emergency repair, staff identified replacement of 250 linear feet of 6 ” clay sewer main on California and failing corrugated metal storm drain pipes at the intersections of Funston and Lawton, Johnson and Orcutt, California and Mill, California and Palm, and Monterey and Toro. Page 359 of 829 Item 6a Complete Street Design Elements The project includes complete street elements and active transportation improvements for many of the streets listed above which are intended to improve mobility and safety for all road users. A summary of the active transportation elements includes: a. Twenty-one new curb ramps b. Three intersections with new Rectangular Rapid Flashing Beacons (RRFBs) and enhanced crosswalk markings c. Over thirty high-visibility crosswalk markings at existing crosswalk locations d. Over a mile of bike lane enhancements, including buff ered and protected bike lanes Below is additional information on the elements implemented for each street: Santa Barbara Avenue (Leff to Broad) The ATP identifies Santa Barbara Avenue between Upham and Broad Streets as a Tier 1 project, with recommendations to install physically protected bicycle lanes. These lanes will offer a protected space for bicycle riders of all ages and ability levels to comfortably travel through this high-priority travel corridor. The bike lane will be separated from the motor vehicle lane with a raised concrete median. The design also includes extending the southbound bike lane and adding a bike box at the southbound approach to the Santa Barbara/Broad Street intersection to improve visibility and safety of cyclists navigating this high-traffic intersection. Implementation of this infrastructure will require eliminating existing on -street parking on the west side of Santa Barbara Street. The combined width of the existing parking lane and striped bicycle lane do not meet minimum widths per City or Caltrans engineering standards, which increases risk of “door zone” collisions. Thus, staff is recommending elimination of the parking lane for safety purposes in addition to following the recommendations in the ATP. Staff has collected data and reviewed the existing parking conditions for properties on Santa Barbara Avenue and determined there is adequate parking availability off -street to support this proposal. Each adjacent property has sufficient on-site parking to support existing demand and there is public parking available across the street at Railroad Square. The community has been notified of this change via a project -specific community workshop, multiple Active Transportation Committee (“ATC”) meetings, direct mailers sent to neighboring properties, and a project webpage. As of the date this report was drafted, staff received one public comments in opposition to the on-street parking removal at this location and has received several comments in support of this proposal. Protected bike lane medians are set back at least 10 feet from driveways to provide clearance for vehicle turning movements and area for placement of private trash bins for weekly collection. Page 360 of 829 Item 6a The project will also improve accessibility and comfort for p edestrians crossing Santa Barbara Avenue. As proposed in the ATP Tier 1 project list, an enhanced pedestrian crossing will be installed at the intersection of Santa Barbara and High Street, including a new Rectangular Rapid Flashing Beacon (RRFB) system, high-visibility crosswalk, and streetlight. Further, existing ramps will be upgraded to current ADA standards at several locations along Santa Barbara. At the February 28, 2023, ATC Meeting, the ATC asked that staff consider designing the RRFB crossing of Santa Barbara at High Street so that a rider on a bicycle would not need to dismount to activate the beacon. Such design requires additional curb ramp design, trenching, and additional beacon system equipment, essentially doubling the cost of this crossing. Consistent with the ATP, accommodating bicyclists to activate the beacon without dismounting is prioritized at intersections with neighborhood greenway routes or other designated bikeways (for example, Toro/Monterey and Pepper/Monterey). Consistent application of active transportation facilities promotes efficiency and familiarity for drivers, bicyclists, and pedestrians. Since adding bicycle activation on a side -street that is not a designated bikeway is inconsistent with the City’s stand ard practices, staff does not recommend adding the additional infrastructure needed to allow bicyclists to activate the crossing without dismounting at this time. Bicyclists will have two ways to legally cross the intersection: 1) stopping as a vehicle and yielding to oncoming traffic before proceeding (without activation of the RRFB), or 2) dismounting and crossing the street as a pedestrian with activation of the RRFB. If the ATC desires to further invest in this crossing in the future, this would be an appropriate use of the annual “Miscellaneous Bicycle Improvements” capital improvement project funds. Figure 2: Proposed Santa Barbara Cross Section Page 361 of 829 Item 6a Figure 3: Santa Barbara Leff to Broad Monterey Street (Santa Rosa to California) Green-backed shared lane markings are proposed for Monterey Street between California and Santa Rosa. While the ATP ultimately plans for protected bike lanes on this segment, it is part of the Tier 2 network (not the highest priority). Protected bike lanes along this segment would require eliminating most, if not all existing on-street parking for the length of the corridor. Proceeding with protected bike lanes along this segment at this time would require significant staff resources for parking analysis and community outreach and would pull funding resources away from other Tier 1 project priorities . Thus, staff is proposing to retain a shared lane configuration on Monterey Street at this time. That said, in addition to the green-backed shared lane markings, the project includes reduced lane widths, “25 MPH” pavement markings and signage to convey appropriate speeds to drivers, and “BICYCLES MAY USE FULL LANE” signs to increase awareness for bicyclists. Additionally, the project includes two new enhanced bicycle and pedestrian crossings at Monterey/Toro Streets (a Tier 2 ATP Project) and Monterey/Pepper Streets (a Tier 1 ATP Project). The crossings will include RRFBs, raised concrete medians, high-visibility crosswalk markings and green bike lane crossings. Additionally, three curb ramps will be upgraded to current ADA standards at several locations along Monterey. RRFBs will have push buttons conveniently located for pedestrians and cyclists to activate the beacon system. Page 362 of 829 Item 6a Figure 4: Monterey Cross Section Figure 5: Monterey Santa Rosa to California California Boulevard (Mill to Monterey) The project includes the installation of green pavement coloring in the existing bike lanes approaching and crossing intersections along California between Mill and Monterey Streets. Additionally, eight curb ramps will be upgraded on California Boulevard. Figure 6: California Cross Section Page 363 of 829 Item 6a Morro Street (Mill to Monterey) The project includes pavement markings and guide signage to complete the Morro Street (Bill Roalman) Neighborhood Greenway from Higuera Street to Mill Street, forming a continuous greenway route between Mill Street and Santa Barbara/Upham Street. The ATP identifies completing the greenway as a Tier 1 high -priority project. Orcutt Road (Laurel to Johnson) The project includes narrowing auto travel lane widths and striping buffered bike lanes on Orcutt Road between Laurel and Johnson, as well as installation of green bike lane markings at intersection conflict areas and transit stops. While the Active Transportation Plan ultimately plans for protected bike lanes on this segment, it is part of the Tier 2 network. Protected bike lanes along this segment would require significant parking removal along the length of the corrido r. Proceeding with protected bike lanes along this segment at this time would require significant staff resources for parking analysis and community outreach and would pull fundin g resources away from other Tier 1 project priorities; thus, staff is proposing buffered bike lanes in the interim and preservation of on-street parking at this time. Figure 7: Orcutt Cross Section Palm Street (Santa Rosa to Pepper) The project includes upgrading four curb ramps along the corridor to current ADA standards as well as striping high visibility marked crosswalks at each stop or signal controlled intersection approaches on the segment. Deferral of Johnson Avenue from 2023 Project Scope Johnson Avenue between Buchon and Laurel Lane was originally within the scope of the 2023 Arterials project. However, most of this work is now recommended for deferral. After collaborating with other City departments early during the design phase in 2022, the northern section of Johnson Avenue (Bishop to Buchon) was removed from the project due to a conflict with an upcoming waterline replacement project planned for 2024. Repaving this segment of Johnson will be deferred until after the waterline project is complete. As of early 2023, the project scope continued to include the southern segment of Johnson (Bishop to Laurel Lane). For multiple reasons detailed below, staff is now recommending that work on this segment of Johnson, with the exception of base repairs, be deferred until the summer 2024 paving project. Page 364 of 829 Item 6a Consistent with previous Council approval of the 2022 Pedestrian Crossing Improvements Project, a “road diet” will be installed on Johnson Avenue between Bishop and Laurel as a pilot installation usin g temporary materials. The road diet will include a reduction from four-to-two auto lanes, with the remaining width used for a continuous center turn lane, buffered bike lanes, on-street parking on both sides, and safety enhancements at the Johnson/Sydney school crossing. This project was originally planned to start construction in fall of 2022, which would have allowed for several months of monitoring before installation of permanent striping as part of the Arterials 2023 paving project. However, challenges with final curb ramp design delayed the Pedestrian Crossing Improvements project bid solicitation by several months. A construction contract has since been awarded and work is anticipated to begin in April 2023, but is unlikely to be completed until as late as June 2023. With the Arterials 2023 project also planned to start later this summer, this would not provide sufficient time to monitor the pilot road diet installation on Johnson before making these changes permanent. Thus, staff is now recommending deferral of pavement maintenance and permanent striping on this segment of Johnson (Bishop to Laurel) until 2024 to provide the community with adequate opportunity to experience the new configuration and staff more time to monitor and make any needed refinements to the final design before permanent striping goes in. Deferring this segment of Johnson to 2024 also provides financial benefits. The Arterials 2023 project predominantly includes pavement reconstruction work, while the 2024 paving project is planned to mostly include slurry seal application on lower-traffic streets that do not require extensive pavement reconstruction. Work associated with pavement reconstruction vs. slurry seal requires different levels of expertise, often with different contractors doing each type of work. Historically, staff has experienced challenges generating interest from potential bidders when projects involve a mix of paving and slurry seal work, as each prime contractor has to subcontract a greater share of the work. Deferring Johnson to 2024 minimizes the mix of paving and slurry seal work, which may solicit more interest from bidders and increase the potential for better pricing, as each respective project would have a simpler project scope. Deferring Johnson Avenue slurry seal work to 2024 and including base repairs to this project will also allow for current funds to be prioritized for streets that are in worse condition and need urgent pavement maintenance. It should be noted that the ATC previously identified the p lanned improvements on Johnson Avenue as their top priority for the Arterials 2023 project, followed by improvements to Santa Barbara Avenue. Because the Johnson Avenue improvements will still move forward in 2023 as a pilot project, with permanent improvements anticipated to come in 2024, staff believes that the current plan of action still honors the priorities of the ATC, while ensuring that staff has adequate time to monitor and refine final design details as necessary. Page 365 of 829 Item 6a Previous Council or Advisory Body Action 1. Annual maintenance for public roadways, including street resurfacing, supports the Council Adopted Major City Goal of Open Space and Sustainable Transportation. 2. This project was originally identified in the 2021-23 Financial Plan approved by Council. 3. Council adopted the Active Transportation Plan on February 2, 2021. 4. June 21, 2022: A City Council study session was held on the City’s Pavement management plan. 5. September 15, 2022: Active Transportation Committee reviewed the preliminary scope and design. 6. February 28, 2023: Active Transportation Committee reviewed the 90% design and formally recommended to Council the paving design as presented to them. Public Engagement Public engagement was conducted during the initial identification of this pro ject as part of the 2021-23 Financial Plan. In addition, three public meetings were held to solicit specific input on the 2023 Arterials project, including two ATC meetings and a community-wide forum held on October 25, 2022, to inform the general public o f the project scope and request input on proposed designs. Postcards or mailers were sent to property owners and businesses impacted by improvements that would reduce or eliminate on street parking. This project is included in the SLO in Motion campaign to provide updated information to the community on current and upcoming construction projects in the public right of way. Updated project information has been maintained throughout the planning and design phase at www.slocity.org/sloinmotion. Project information has also been shared via social media and direct mailers. CONCURRENCE This project has been reviewed and has concurrence from the Utilities and Public Works Departments, including the Transportation Manager and City Engineer. The Active Transportation Committee has reviewed and is supportive of the proposed pedestrian and cyclist improvements. Additionally, the project has been reviewed and has concurrence from the SLO City Fire Department. ENVIRONMENTAL REVIEW The Project consists of the repair and maintenance of existing roadways, sidewalks, gutters, curb ramps, and storm drain infrastructure in eight locations within the City, all within existing road right-of-way. A portion of the Project is located within a potentially archaeologically sensitive zone and appropriate monitoring will be in pace in the event any sensitive archeological resources are encountered during the project . The final scope and location of the Project is consistent with the previously-adopted Initial Study/Mitigated Negative Declaration (IS/MND) ER10-07, which addressed trenching and improvements within sensitive areas. Mitigation measures approved through IS/MND ER10 -07 are included in the Project’s specifications and will be followed by the City’s contractor, consistent with the requirements of the California Environmental Quality Act (CEQA). Page 366 of 829 Item 6a The complete street elements are consistent with the Land Use and Circulation Element as well as the ATP, therefore consistent with the environmental review of those certified documents. In addition, the types of complete street improvements proposed as part of this Project would all be considered categorically exempt from CEQA in the category of Existing Facilities, maintenance activities (CEQA Guidelines § 15301.) Therefore, no additional environmental review is required.

If funding is not sufficient to support all of this project’s needs, only portions of the contract would be awarded to reflect the work than can be completed within the available budget. In order to allow for project implementation during the summer months, and to lessen impacts to the traveling public, staff is recommending this project be approved for advertisement now. The project is structured with a Base Bid and two Additive Alternatives to maximize the scope of the rehabilitation project within the available funding. The strategy is to award the contract with the Base Bid and as many of the Additive Alternatives as funding will allow, up to the Publicly Disclosed amount of $7,350,000 in compliance with Public Contract Code Section 20103.8(c). The Streets Reconstruction and Resurfacing account (2001001) has a balance of $474,475 of which $250,000 is programmed for use for this project. The remaining balance of $224,475 is proposed to remain in the account to allow for future project use as well as funding for pavement failures that may occur over the course of a year. The project’s funding plan relies on approval of a funding request in the amount of $6,850,000 in fiscal year 2023-24 which is included in the draft 2023-25 Financial Plan. Due to the number of multi-modal transportation improvements proposed in this project, the Active Transportation Plan Implementation Account (2000608) will contribute $285,000 in Fiscal Year 2023-24 towards this project. Funding for the storm drain replacement work at the intersections of Funston and Lawton, Orcutt and Johnson, California and Mill, California and Palm, and Monterey and Toro is proposed to come from the CMP Storm Drain Replacement Account (2090742) which currently has a balance of $82,203. Project funding also relies on a funding request of $1,800,000 in fiscal year 2023-24 which is included in the draft 2023-25 Financial Plan. Page 368 of 829 Item 6a Where asphalt pavement is replaced, the project will incorporate upgrades to water valve and sewer maintenance hole covers which is funded by the Water Valve Cover Adjustments Account (2001005) and Sewer Maintenance Hole Cover Adjustments Account (2000084). Funding for sewer replacement work on California Blvd. and sewer manhole coating is proposed to come from Sewer Fund’s Undesignated Capital account (602.9501.71501) to provide adequate funding for the project. Undesignated Capital has a current available balance of $174,052. An additional $100,000 is expected to become available within Undesignated Capital after completion of the Verde/Luneta/Ramona/Broad Sewer Replacement project (1000091), which is currently being constructed and is 95% complete and under budget. This project’s construction contract will not be awarded unless sufficient funding exists to support the work, including contingencies. Actual costs will be known when the project opens for bid. ALTERNATIVES Deny authorization to advertise. The City Council may choose not to authorize project advertisement. Staff does not recommend this alternative because this is the ideal time to advertise paving projects for summer construction.

The project is located within public right-of-way at the intersection of Monterey Street and Toro Street in San Luis Obispo, California (see Figures 1 through 3, provided in Appendix A). The City’s 2009 Archaeological Resource Preservation Program Guidelines (Guidelines), developed by the Cultural Heritage Committee (CHC), Section 1.30 define archaeologically sensitive areas and sites as: A. Areas inside or within 200 feet (ft) (61 meters) of the boundaries of an archaeological site shown on United States Geological Survey (USGS) topographic maps on file in the Community Development Department and/or recorded with the Central Coast Information Center (CCIC); B. Areas within 200 ft of top of banks of San Luis Obispo, Stenner, Brizzolara, Acacia, Old Garden, Prefumo, and Froom Creeks; C. Areas inside a Historical District or within an area designated as being archaeologically sensitive, or within a burial sensitivity area as shown on maps on file at the Community Development Department; D. Sites designated on the Master List of Historic Resources, or determined to be eligible for listing on the National Register of Historic Places (National Register) or California Register of Historical Resources (California Register) (California Public Resources Code [PRC] Section 5024.1 (a)); E. Sites within a historically or archaeological sensitive designated by the CHC, City Council, or other governmental agency; or F. Sites identified as being sacred places or Traditional Cultural Properties as defined in National Register Bulletin 38, Guidelines for Evaluating and Documenting Traditional Cultural Properties by Northern Chumash community members who have been identified by the California Native American Heritage Commission (NAHC) as having ancestral ties to San Luis Obispo County, or by other local tribal representatives similarly recognized by the NAHC. (City of San Luis Obispo 2009: 8–9) The City’s Guidelines are a model for the identification, evaluation, and preservation of archaeological and other cultural resources in the City. They are based upon and implement policies in the City’s General Plan Land Use Element and Conservation and Open Space Element, and are part of the City’s environmental review process. Per Section 4.50 of the Guidelines, construction monitoring may be required if there is a possibility that significant or potentially significant archaeological resources are present in the impact zone of a construction project and that it is not reasonable to conduct additional physical investigations prior Page 448 of 829 A RCHAEOLOGICAL M ONITORING P LAN M ARCH 2023 M ONTEREY S TREET AND T ORO S TREET C URB R AMP I MPROVEMENTS P ROJECT S AN L UIS O BISPO, C ALIFORNIA P:\CBZ1801.16 SLO Monterey Toro AMP\AMP\Monterey Toro Monitoring Plan.docx (03/22/23) 2 to construction (City of San Luis Obispo 2009: 18). This Plan implements Section 4.50 and presents the project’s background setting, construction monitoring procedures, criteria for evaluating cultural resources identified during construction, and methods for archaeological data recovery and mitigation (if required). Per Section 4.50 of the Guidelines, the City must review and approve this Plan prior to commencement of construction for the project. PROJECT DESCRIPTION The project involves approximately 50 feet of storm drain work at the intersection of Monterey Street and Toro Street. According to project plans provided by the City (see Appendix B), construction activities will include excavation (via trenching) to open new trenches, installation of new pipelines, backfilling/closing the trench, and replacing asphalt or concrete. BACKGROUND RESEARCH Section 4.50 of the City’s Guidelines requires construction monitoring if it is not reasonable to conduct additional physical investigations prior to construction. Due to the paved nature of the project site, physical investigation of the project site was not reasonable. To determine which portions of the project site are sensitive for cultural resources, per Section 1.30 of the Guidelines, a record search for the project site and a 0.125-mile radius was conducted at the CCIC of the California Historical Resources Information System at the Santa Barbara Museum of Natural History. The CCIC, an affiliate of the California Office of Historic Preservation (OHP), is the official repository of cultural resources records and reports for the County of San Luis Obispo (County). The record search results indicate that 1 previous cultural resources study has included the entirety of the project site and that 7 previous cultural resources studies have included a portion of the 0.125-mile search radius (CCIC Record Search 22-023; see Appendix C). The previous cultural study that included the entirety of the project site (SL-02651) was a survey. The 7 previous studies consist of 5 surveys (SL-00719, SL-03934, SL-04929, SL-05033, and SL-05797), 1 Phase II archaeological excavation (SL-04978), and 1 historic built environment study (SL-06905). In total, 100 percent of the project site and 0.125-mile radius has been studied. No archaeological cultural resources have been recorded within the project site or within the 0.125-mile radius as a result of previous cultural resources studies. PROJECT AREAS TO BE MONITORED Based on the results of the record search at the CCIC as well as an examination of maps, archaeological monitoring is required for the entirety of the project. While no archaeological cultural resources have been recorded within the project site or within 0.125-mile of the project site, the project site is located within the general vicinity of Downtown San Luis Obispo and Mission San Luis Obispo de Tolosa, as well as San Luis Obispo Creek. For this reason, the project site is in an area of high archaeological sensitivity and archaeological monitoring is required for all ground disturbance in native sediments. As such, full-time monitoring is required during project excavation activities for storm drain installation (see Appendix A, Figure 3).

Jones et al. (2007) employ a chronological system for Central Coast Prehistory that incorporates periods, locally defined phases, and regional cultures. For San Luis Obispo and the Central Coast, the six periods of cultural chronology are Late, Middle/Late Transition, Middle, Early, Milling Stone/Early Archaic, and Paleo- Indian (see Table A) (Jones et al. 2007). Table A: Chronological Sequence of the California Central Coast Period Temporal Span (A.D./B.C.) Temporal Span (B.P.) Late A.D. 1250 to 1769 700 B.P. to historic Middle/Late Transition A.D. 1000 to 1250 1000 to 700 cal B.P. 1 Middle 600 B.C. to A.D. 1000 3000 to 1000 cal B.P. Early 3500 to 600 B.C 5500 to 3000 cal B.P. Milling Stone/Early Archaic 8000 to 3500 B.C. 10,000 to 5500 cal B.P. Paleo-Indian Pre-8000 B.C. Pre-10,000 cal B.P. Source: Jones et al. (2007) 1 cal B.P. is calibrated years before present. Paleo-Indian Period (Pre-10,000 cal B.P.) Early human presence in San Luis Obispo is suggested only by fluted project points from two locations in San Luis Obispo County: Nipomo and near Santa Margarita. However, no other evidence has been found to suggest habitation during this period (Jones et al. 2007: 135). Milling Stone Culture (10,000 to 5500 cal B.P.) The Milling Stone Culture is marked by “large numbers of well-made handstone and/or milling slabs, crude core and cobble-core tools, and less abundant flake tools and large side-notched projectile points” (Jones et al. 2007: 135). Pitted stones, contracting stemmed points, lanceolate points, and crescents have also been found in the context of some Milling Stone sites. Occupation dating to the Milling Stone period has been identified at no fewer than 42 sites in various settings—rocky coasts, estuaries, and nearshore interior valleys. As very few sites with Milling Stone components have been found farther than 15 miles from the shore and most interior Milling Stone sites produce marine shells, it is believed that many groups from the Milling Stone period maintained some form of a connection with the coast (Jones et al. 2007: 135-137). Early Period (5500 to 3000 cal B.P.) The Early Period is marked by the co-occurrence of contracting-stemmed and Rossi square-stemmed points, as well as large-notched type points leftover from the Milling Stone Culture. Ground stone assemblages from the Early Period contain handstones and milling slabs, along with pitted stones. During this period, portable mortars and pestles appeared and the frequency of cobble-core tools decreased (Jones et al. 2007: 138). Page 450 of 829 A RCHAEOLOGICAL M ONITORING P LAN M ARCH 2023 M ONTEREY S TREET AND T ORO S TREET C URB R AMP I MPROVEMENTS P ROJECT S AN L UIS O BISPO, C ALIFORNIA P:\CBZ1801.16 SLO Monterey Toro AMP\AMP\Monterey Toro Monitoring Plan.docx (03/22/23) 4 Middle Period (3000 to 1000 cal B.P.) Middle Period sites contain assemblages of contracting-stemmed points. These sites are also marked by the disappearance of the square-stemmed and large side-notched points. Ground stone assemblages reveal continued use of both slabs/handstones and portable mortars/pestles. Pitted stones and groove stone net sinkers are also commonly found at Middle Period sites. Bone flutes are occasionally found in association with burials dating to the Middle Period, and other burial accompaniments include bone tubes and Olivella beads. Toward the end of the Middle Period, smaller leaf-shaped projectile points appeared, marking the arrival of bow-and-arrow technology (Jones et al. 2007: 138-139). Middle/Late Transition (1000 to 700 cal B.P.) The transition between the end of the Middle Period and the beginning of the Late Period was marked by dramatic changes in assemblages and settlement patterns. This change was evidenced by the appearance of large numbers of arrow points, the disappearance of most stemmed points, and changes in bead types. The transition time dates slightly differently for various Chumash tribes, but in San Luis Obispo County, the transition occurred sometime between A.D. 900 and A.D. 1280. Archaeological site CA-SLO-9 contained an assemblage dating to this time that was dominated by contracting-stemmed projectile points, small leaf-shaped arrow points, notched line sinkers, circular shell fishhooks, and Olivella saucer beads (Jones et al. 2007: 139). Late Period (700 B.P. to historic) Late Period sites contain assemblages consisting of large numbers of Desert side-notched and Cottonwood arrow points, small bifacial bead drills, bedrock mortars, hopper mortars, lipped and cupped Olivella beads, and steatite disk beads. The period is marked by single-component sites concentrated in the interior of the region, as opposed to concentrated in the coastal part of the region. Many sites dating to the Late Period are marked by small middens with associated (or nearby) bedrock mortars. ETHNOHISTORY The project site is within an area prehistorically occupied by the Northern (Obispeño) Chumash. The Obispeño Chumash are a subdivision within the larger Chumash cultural family and are named after their historical attachment to Mission San Luis Obispo de Tolosa, which was founded in 1772 (Greenwood 1978: 520). Early accounts of the Obispeño Chumash imply a hunter-gatherer lifestyle, but other aspects of accounts indicate that there was also a high-level sociopolitical complexity (Jones et al. 2007: 129). Additionally, a house floor measuring 30 ft in diameter at Morro Bay was discovered during excavations (Greenwood 1978: 520), suggesting the existence of sedentary villages. There are fewer historical accounts and ethnographic studies of the Obispeño Chumash than for the Chumash of the Santa Barbara Channel. No villages were recorded by European visitors to the area; Pedro de Unamuno (1587), Sebastian Cermeño (1595), Gaspar de Portolá (1769), and Lieutenant Pedro Fages (1772) all kept diaries, but none of them described large or heavily populated villages like those seen along the Santa Barbara Channel (Greenwood 1978: 520). While none of these Page 451 of 829 A RCHAEOLOGICAL M ONITORING P LAN M ARCH 2023 M ONTEREY S TREET AND T ORO S TREET C URB R AMP I MPROVEMENTS P ROJECT S AN L UIS O BISPO, C ALIFORNIA P:\CBZ1801.16 SLO Monterey Toro AMP\AMP\Monterey Toro Monitoring Plan.docx (03/22/23) 5 expeditions reported large villages and, at the same time, the 30 ft house floor was found in Morro Bay in what is reportedly within sight of the Portolá camp, it is possible that villages flourished and declined before the years of European exploration. By the time historical contact occurred, the majority of Chumash houses were small, round, and domed. Other individuals apparently lived out in the open, and some dwellings near Morro Bay were constructed as a round hole with branches for a roof (Greenwood 1978: 521). While the archaeological record demonstrates that the Chumash exploited marine food resources, conditions did not favor the canoe and most marine food was harvested by hand, trap, pole, net, and hook-and-line from tidal pools and shallow waters (Greenwood 1978: 522). Obispeño chiefs had many wives and retained the right to divorce them. Social rank was derived from material wealth, and the chief received offerings of food, goods, and beads from those in the village (Greenwood 1978: 523). In 1914 and 1915, the last Obispeño speaker (Rosario Cooper) provided some details of Chumash life to American linguist and ethnologist J.P. Harrington, including cures for witchcraft, beliefs in nature, dances associated with the swordfish and coyote, and offerings thrown to the swordfish in Avila. Cooper also told Harrington of a game played with wild walnuts filled with brea (i.e., tar or pitch), and of material culture items like brooms of juncus stalks, sleeping mats, foxskin quivers, and the use of white clay for shampoo (Greenwood 1978: 523). Following the establishment of the mission in San Luis Obispo and the conversion of the Chumash people, already-declining coastal villages suffered high mortality rates and the villages became barely inhabited. Obispeño culture also rapidly disappeared as a result of missionization (Greenwood 1978: 523). In 1803, Chumash population at the Mission was recorded to be 919; by 1838, the population was down to 170. By the time the Bureau of Indian Affairs compiled the Roll of 1928, only four Native Americans claimed to be survivors of San Luis Obispo neophytes (Greenwood 1978: 521). HISTORY Following its founding in 1772, Mission San Luis Obispo de Tolosa quickly became self-sufficient, and it was used as a stopover for those traveling between missions to the north and south of San Luis Obispo (HRG 2013: 13–14). Spanish and Mexican ranchos extended across what is now San Luis Obispo County but were subdivided after California’s admission to the Union in 1850 and the California Land Act of 1851. The California Land Act caused many rural landowners in the County to migrate into the City of San Luis Obispo, which was designated as the County seat in 1868. The Southern Pacific Railroad arrived in town in the late 1890s, and the California Polytechnic Institute (now California Polytechnic University, San Luis Obispo) (Cal Poly) was established in 1901 (HRG 2013: 14). The Mission and Cal Poly influenced the community’s growth, as did William Randolph Hearst’s San Simeon Ranch, which is more commonly known today as Hearst Castle. Development in San Luis Obispo began to expand in the 1900s due to the advent of the automobile, and tourism—particularly automobile tourism—played a role in the area’s continued development. While it affected most of the country, the Great Depression’s economic impacts in San Luis Obispo were mitigated by the establishment of a military training camp, Camp San Luis Obispo. The establishment of the camp led to a dramatic increase in population, and the camp continued to draw in military families as training activity increased in preparation for World War II Page 452 of 829 A RCHAEOLOGICAL M ONITORING P LAN M ARCH 2023 M ONTEREY S TREET AND T ORO S TREET C URB R AMP I MPROVEMENTS P ROJECT S AN L UIS O BISPO, C ALIFORNIA P:\CBZ1801.16 SLO Monterey Toro AMP\AMP\Monterey Toro Monitoring Plan.docx (03/22/23) 6 (HRG 2013: 15). Many soldiers permanently settled in San Luis Obispo after returning from the war, which spurred a need for single-family housing in the 1950s and 1960s (HRG 2013: 15). The United States Census Bureau estimates that, as of July 1, 2017, the population of the City of San Luis Obispo was 47,541.

Native American monitors will not initially be on site during construction. The archaeological monitor for the project will be a Registered Professional Archaeologist (RPA) or will be under the direct supervision of the RPA. Monitors will be thoroughly briefed in monitoring methodology, responsibilities, procedures, safety requirements, and rules. The archaeological monitor will also retain a copy of this Monitoring Plan while on duty. For this project, the LSA Project Manager and Project Archaeologist (Kerrie Collison, M.A., RPA No. 28731436) will oversee monitoring operations. The archaeological monitoring schedule will be coordinated with the City Inspector or other City staff (or their designated representative) as appropriate. MONITORING PROCEDURES Prior to the commencement of excavation activities on the first day of monitoring, an LSA archaeologist will provide cultural resources awareness training to construction personnel. This training should be in the form of a presentation and handout describing the types of possible archaeological deposits that may be encountered during construction activities and the procedures that should be used in the event of inadvertent discoveries of cultural resources during construction. All ground-disturbing activities within the designated monitoring areas, including clearing, grubbing, tree removal, grading, boring, digging, trenching, and other related activities will be monitored by the archaeological monitor. The archaeological monitor will record archaeological deposits identified during monitoring, unless field observations indicate that the deposits are not in situ. The monitor will complete a daily form that identifies the date and location of the monitoring as well as any cultural resources that are identified. Photographs will be taken of monitoring activities and as part of resource documentation, as necessary. If archaeological cultural resources are identified during monitoring, the monitor will be empowered to temporarily halt construction and flag the resource to protect it from project activities that may disrupt it. The monitor will make an initial assessment of the potential for the find to qualify as a historical or unique archaeological resource under the California Environmental Quality Act (CEQA) (PRC Sections 21084.1 and 23082.3), and as warranted, make recommendations for additional analysis necessary (including excavation) to formally evaluate the eligibility of the find for the California Register. Eligibility of the resource for the California Register would depend on a combination of factors, including the horizontal and vertical extent of the archaeological deposits, the type and relative abundance of archaeological material found, and the extent of prior disturbance of the deposits, if any. Archaeological materials can include artifacts, ecofacts, and discrete features. LSA will immediately notify the Community Development Director (Director) of any archaeological finds during project work, per Section 4.60.1 of the City’s Guidelines.

If the find is not human remains, the area of the archaeological find would be flagged for avoidance at a distance determined by the monitor to avoid impacts to the resource by construction activities. The monitor would determine whether the find is an isolate (one or two cultural items located within 50 meters [164 ft]) of a site (three or more cultural items within 50 meters). If the find is determined to be an isolate, its location would be recorded using a handheld global positioning system (GPS) unit, the material collected, the resource characteristics recorded, and construction activities allowed to resume. If the find is determined to be an archaeological site, earth-moving activities would be diverted until the site type and boundary can be determined by following appropriate testing-evaluation procedures (discussed in further detail in Archaeological Site Testing on page 10 of this Plan). Regardless of whether the find is an isolate or site, all resources would be photographed and mapped using GPS, and descriptive notes would be taken before construction work would be allowed to resume. HUMAN REMAINS If human remains are found, the requirements of State Health and Safety Code Section 7050.5 must be met. State Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the County Coroner has made a determination of origin and disposition pursuant to State PRC Section 5097.98. The County Coroner must be notified of the find immediately. If the remains are determined to be Native American, the County Coroner would notify the Native American Heritage Commission, which would determine and notify a Most Likely Descendant (MLD). With the permission of the landowner or his/her authorized representative, the MLD may inspect the site of the discovery. The MLD shall complete the inspection and make recommendations or preferences for treatment within 48 hours of being granted access to the site. The MLD recommendations may include scientific removal and nondestructive analysis of human remains and items associated with Native American burials, preservation of Native American human remains and associated items in place, relinquishment of Native American human remains and associated items to the descendants for treatment, or any other culturally appropriate treatment. In brief, the area of the find of human remains would be flagged off so that construction activity within at least 25 ft of the discovery would be redirected elsewhere, and the County Coroner (as well as the Director) would be notified immediately. Project activities would avoid any impacts to the human remains. NATIVE AMERICAN MONITORING A Native American tribal representative would be contacted in the event that Native American artifacts are encountered during ground-disturbing activities. If this were to occur, the Native American tribal representative would be invited to observe remaining project ground-disturbing activities for additional Native American artifacts.

If no archaeological cultural resources are found during construction, the monitoring report would be a brief letter report submitted to the Director. If monitoring is positive and results in the identification of cultural resources, the report would be consistent with the Guidelines of the State Office of Historic Preservation’s Archaeological Resource Management Reports (ARMR): Recommended Contents and Format (OHP 1990) and would be submitted to the Director. A positive findings report would include the following information: 1. The location and dates of monitoring. 2. The methodology and procedures for field and laboratory work. 3. The location, description, and eligibility determination of the cultural resource(s) found during monitoring. 4. All forms (archaeological monitoring, photographic record, and artifact record) completed as a part of monitoring would be provided as appendices to the report. State of California Department of Parks and Recreation (DPR) Series 523 forms would be prepared in accordance with the guidelines established by the OHP for cultural resources found during the project. 5. The status of curation of the material found. Copies of any report prepared for this project would be submitted to the City and to the CCIC.

The LSA Project archaeologist will contact the City and determine whether archaeological site testing is necessary. If determined necessary, archaeological site testing would be conducted to evaluate site importance/significance and, therefore, site eligibility for listing in the California Register. The archaeological site testing procedures will be conducted in a manner consistent with standard accepted professional archaeological methodology. Testing procedures can include surficial artifact collection, and excavation using shovel test pits (STPs), 1x1 meter excavation units, mechanized trenching, or a combination of these methods. Fieldwork Test excavation will consist of the excavation of STPs and 1x1 meter units. These excavations will be used to determine the character, integrity, and vertical (depth) and horizontal (size) extent of the site. Placement of STPs will be on a north-south axis or along the axis of greatest site length, whichever is more appropriate for a particular site. STPs will be excavated to determine the extent of midden deposits and to generally identify site areas where cultural material exists in quantity. STPs will measure approximately 40 centimeters (cm; 16 inches) in diameter and will be hand- excavated in 20 cm (8-inch) levels to a culturally sterile level or to a depth no greater than 100 cm (39 inches). Sediment from each STP level will be passed through 1/8-inch mesh screen and all cultural material will be saved in labeled Ziploc bags. Notes recorded at the time of excavation will identify sediment color, depth, and cultural material from each STP. Bagged material will be transported to the LSA laboratory for cleaning, sorting, identification, analysis, and curation. Based on the results of the STPs, units will be excavated to more accurately identify material density and depth. Units will be placed in areas of the site shown to contain the greatest potential for finding the deepest midden deposits, as well as the greatest quantity and diversity of cultural material. Excavation units will be hand-excavated in 10 cm (4-inch) levels following the natural surface contour. Excavated sediment will be screened through 1/8-inch mesh and cultural material from each level will be saved in labeled Ziploc bags. Bagged material will be transported to the LSA laboratory for cleaning, sorting, identification, analysis, and curation. Unit excavation will cease when sterile sediment or bedrock is encountered. During the course of unit excavation, if a distinct sediment type is identified, excavation may change to follow this new contour in 10 cm (4-inch) levels until it disappears or until another change occurs, whereupon excavation following the natural surface contour will resume. Once excavation ends, an STP may be placed in the unit floor to confirm that additional cultural material does not exist below what is thought to be the bottom of the unit.

Fire-affected rock will be counted and weighed. Notes, measurements, and drawings will be recorded on unit level forms during excavation. Items and samples given exact provenance will be sketched on the floor plan of the appropriate level form. After excavation, one wall of each unit will be profiled and photographed. The wall selected will be the wall displaying the most representative stratigraphic development, including residual features. Distinctive subsurface horizons will be described by sediment type and color using the Munsell Color Chart. LABORATORY ANALYSIS All collected material remains the property of the landowner (for this project, the City). All artifacts and ecofacts collected during monitoring will be taken to the LSA laboratory where they will be cleaned and prepared for analysis. Cataloging and processing will take place based on methods for each material class; material will be cataloged as individual artifacts or as groups of ecofacts, as appropriate. Items may be analyzed by specialists, as warranted. Ecofactual material such as (nonhuman) bone, charcoal, and/or shell may be submitted for radiocarbon testing that can reveal the age of the material analyzed. Similarly, artifacts made of obsidian (volcanic glass) may be submitted for sourcing and hydration analyses that will reveal the geochemical source and time of manufacture. Other specialized studies may be conducted but will be dependent upon the presence of material. Items such as beads and fish ear bones (otoliths) can provide information on chronological site occupation and seasonality, although these items must be found before specialized studies can occur. Items will be prepared for curation in accordance with standardized curation guidelines and will be temporarily curated at LSA until they are deposited with an approved curation facility. LSA anticipates that curation of any items recovered during this project will take place at the San Luis Obispo County Archaeological Society (SLOCAS) Curation Facility on the Cuesta College campus. Final cataloging and artifact preparation will be consistent with SLOCAS requirements. SITES NOT ELIGIBLE FOR THE CALIFORNIA REGISTER Should site testing indicate the site is not eligible for listing in the California Register, then the resource shall be fully recorded on DPR Series 523 Forms and construction activities allowed to resume. SITES ELIGIBLE FOR THE CALIFORNIA REGISTER Series 523 DPR forms will be completed to record site location and to provide material descriptions. Completed forms will be appended to the monitoring report. Should site testing indicate that the site may be eligible for listing on the California Register, then adverse effects to the resource shall be avoided, or effects mitigated. Avoidance of impacts to resources is always the preferred alternative, although where avoidance is not feasible, mitigation of impacts to a resource can consist of, but is not limited to, excavation in accordance with a data recovery plan.

Such studies shall be deposited with the California Historical Resources Regional Information Center. Archaeological sites known to contain human remains shall be treated in accordance with the provisions of Section 7050.5 Health and Safety Code. As such, if a resource determined to be important and eligible for listing in the California Register is found during the project, then an attempt to avoid the resource through project redesign or other means would be made. If it is determined that the only feasible alternative is excavation and removal of the resource, a data recovery plan shall be written describing the scientific methodology to be employed during excavation. The data recovery plan will employ a research design to guide the excavation. Any studies developed as part of this effort will be reported upon in a manner that adheres to current professional standards, and reports will be filed with the City and the CCIC. If additional material is exposed at the same site after impacts have been mitigated, additional mitigation (excavation) will not be required unless the new material represents a new type of data (artifact classes and/or features) not recovered during previous mitigation.

INTRODUCTION Our field work consisted of deflection testing using our falling weight pavement deflection testing device in general accordance with CTM 356, coring to measure the existing pavement thickness, and a visual condition survey. This work was performed by Brett Long and Ryan Burrell of PEI’s staff. Visual evaluations were performed by Joseph Ririe of PEI’s engineering staff. The traffic indexes used in this analysis were provided by the City of San Luis Obispo. We have summarized our analysis on the deflection summary sheets for the street segments following this report. Included on the summary sheets are the coring data for existing pavement thickness, visual condition survey, deflection test results analysis, and rehabilitation recommendations. ANALYSIS The rehabilitation alternatives have been designed using structural requirements from the deflection analysis contained in CTM 356, reflective cracking criteria, and the visual condition survey. Reflection cracking requirements are determined as a minimum of one-half the bonded laye r section per current Caltrans recommendations for reflective cracking. Engineering judgment and experience has been used in applying these criteria to the individual street segments. The rehabilitation alternatives evaluated in this analysis include HMA and RHMA overlays, milling and replacement with HMA, and Cold In-Place Recycling (CIR). Reconstruction alternatives are also provided including Full Depth Reclamation (FDR), Full Depth HMA, and HMA over aggregate base.

The minimum recommended overlay thickness is 1-3/4 inches to ensure that the HMA can be properly compacted. For HMA overlays, typically a 1/2-inch HMA leveling course is recommended if pavement fabric is placed. The leveling course provides a uniform surface and fills cracks to ensure the fabric is bonded properly to the overlay. PEI recommends placing a 1/2-inch leveling course under RHMA overlays. The leveling course helps provide a uniform surface for placing the RHMA to ensure the thickness of the RHMA overlay. Minimum thickness for RHMA overlays is critical for compaction. MILLING AND REPLACEMENT Milling and replacement is generally recommended when overlay requirements for reflective cracking exceed 3-1/2 inches and are structurally adequate by deflection. Overlays which exceed 3-1/2 inches are not usually feasible due to geometric constraints. Mill and replacement alternatives allow for resurfacing the pavement to match the existing profile. This alternative can also reduce the lift thickness to meet reflective cracking requirements if the pavement is structurally adequate. The expected pavement life for milling and replacing is similar to an overlay. Milling and replacement is a green alternative also, because asphalt suppliers use the removed asphalt in Rap (recycled asphalt pavement) mixes. PEI does not recommend Milling and Replacement when the pavement is less than 5 inches thick. Construction traffic can cause significant failures in pavements that are milled and leave less than 3 inches. PARTIAL DEPTH RECYCLING(PDR) PDR is an option when pavements are structurally adequate or slightly structurally deficient. It can be especially useful when pavements are thick (greater than 6 inches). PDR helps reduce crack history in thicker pavement and provides a green approach by using existing materials. PDR consists of either an emulsion process or a foaming process. The cold foam process can include mixing aggregate base with the asphalt.

Full Depth HMA is the fastest for construction but typically has higher costs than other reconstruction alternatives. FDR HMA can be a cost-effective approach but takes much longer to construct than HMA. HMA over aggregate base has a lower cost than Full Depth HMA but has significant impact on the public due to the slower construction process. PROJECT ANALYSIS AND DESIGN OVERVIEW The streets segments that were evaluated are listed below: •La Loma Court – Los Cerros Drive to End •Higuera Street – South Street to Los Osos Valley Road •Johnson Avenue – Buchon Street to Laurel Lane •Madonna Road – HWY 101 to Higuera Street •California Boulevard – Phillips Lane to Monterey Street •Orcutt Road – Laurel Lane to Johnson Avenue •Orcutt Road – Johnson Avenue to Tank Farm Road •Santa Barbara Avenue – Leff Street to Broad Street •Grand Avenue - Slack Street to Monterey Street All the street segments experience higher truck traffic loading (traffic indexes of 8.5) except for La Loma Court, which was designed at a traffic index of 5.5. The structural deficiencies vary from slight to substantial. PEI evaluated multiple alternatives for rehabilitating the pavements. The estimated design life of each recommended alternative is provided in the following table: Proposed Treatment Expected Service Life HMA and RHMA Overlays 7-12 years Milling and Replacement 7-12 years Partial Depth Recycling (PDR) 7-12 years Full Depth Reclamation (FDR) 15-20 years Full Depth HMA 15-20 years HMA Over Aggregate Base 15-20 years Page 486 of 829 Z:\Shared\R Drive\Active Projects\San Luis Obispo, City of\220205\Test Results\ER01\220205_ER01.doc Anthony Ramos October 05, 2022 Project No. 220205 Page 4 Each alternative should be evaluated by the design engineer for cost , constructability, and impact on the public during construction. The Deflection Summary Sheets following this report provide the coring data, deflection data, and visual condition evaluations used in PEI’s analysis. The recommended repair strategies have been provided for rehabilitation alternatives. Following the summary sheets are the deflection data print outs, R-values, and photos. MATERIALS AND CONSTRUCTION HMA recommended for leveling courses less than 1 inch should be constructed using 3/8-inch maximum HMA or #4 mix. The leveling course should be rolled and compacted with an 8 to 12 ton pneumatic-tire roller. HMA with thicknesses of 1 to 2 inches should be constructed using 1/2-inch maximum HMA. HMA layer thicknesses greater than 2 inches can be constructed with either 1/2 or 3/4-inch maximum HMA. RHMA should be constructed with 3/8-inch maximum aggregate for overlays less than 2 inches and 1/2-inch maximum size aggregate for overlays greater than or equal to 2 inches. All HMA and RHMA work should be placed in accordance with Caltrans 2010 Section 39 using the standard process. LIMITATIONS This report has been prepared based on the indicated field testing and application of our knowledge of pavement technology. The repair strategies in this report are based upon industry standards. Our professional services were performed, findings obtained, and recommendations prepared in accordance with generally accepted engineering principles and practices. No warranty is either expressed or implied. SUMMARY We performed deflection testing for the 2023 City of San Luis Obispo Arterial Improvement Project and have provided recommendations and repair strategies for resurfacing or reconstructing the pavements of each street segment.

Some areas of alligator cracking have progressed to base failure in the wheel tracks. Previous maintenance includes trench utility repairs. ANALYSIS The existing pavement consists of 6-3/4 to 10 inches of asphalt concrete over 6 to 8-1/2 inches of aggregate base. PEI could not identify if pavement fabric was present in the asphalt concrete layer. The native soil is a brown clay with an R-value of 11. Based on the deflection analysis, the pavement is structurally deficient by up to 1-1/4 inches of HMA.

Overlaying with HMA is not recommended because the overlay exceeds what would allow for meeting geometric constraints. RECOMMENDATIONS Overlay Options HMA Overlaying with HMA is not recommended because the thicker overlay exceeds what would allow for meeting geometric constraints. RHMA We recommend 10-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course and a 2-inch RHMA overlay. The pavement should be evaluated for the base failures present. If the amount of base failure exceeds 10%, then placing overlays may not be cost effective. Milling and Replacement Option HMA We recommend milling off 2-3/4 inches of the existing pavement, 8-inch pavement repairs of base failures, placing a 3/4-inch HMA leveling course and a 2-inch HMA overlay. RHMA We recommend milling off 2-3/4 inches of the existing pavement, 4-inch pavement repairs of base failures, placing a 3/4-inch HMA leveling course and a 2-inch RHMA overlay. Partial Depth Recycling Option (PDR) We recommend milling off 2-1/2 inches of the existing pavement, Partial Depth Recycling (with Emulsified Asphalt or Foamed Asphalt) to a depth of 3 inches, 8-inch pavement repairs of base failures and placing a 2-1/2-inch RHMA overlay. FDR Option We recommend uniformly pulverizing 16 inches of existing asphalt concrete, aggregate base, and native soil, removing 7 inches of pulverized material, treating the remaining pulverized material and native soil with cement/lime to a depth of 14 inches and placing 7 inches of new HMA in 3 lifts. This recommendation is based on an unconfined compressive strength (UCS) of 300 psi. Reconstruction Options Full Depth HMA We recommend removing to a depth of 12-1/2 inches and placing 12-1/2 inches of HMA in 5 lifts. Page 491 of 829 Deflection and Structural Summary Project No. 220205 2023 Arterial Pavement Improvement Project Client: City of San Luis Obispo HMA over Aggregate Base We recommend removing to a depth of 20-1/2 inches, installing a SEG fabric, placing 15 inches of aggregate base and 5-1/2 inches of HMA in 2 lifts. Both reconstruction alternatives could develop unstable grade from construction traffic during the construction process. Stabilization allowances should be included if one of these alternatives is chosen. As previously discussed in the report, rehabilitation alternatives may have different anticipated service lives. The design engineer should evaluate each alternative based on cost, constructability, and impact on the public.

Some areas of alligator cracking have progressed to base failure in the wheel tracks. Previous maintenance includes utility repairs and slurry sealing. The slurry seal is in poor condition. ANALYSIS The existing pavement consists of 6-1/2 to 15 inches of asphalt concrete over 0 to 17 inches of aggregate subbase. PEI could not identify if pavement fabric was present in the asphalt concrete layer. The native soil is a brown clay with R-values ranging from 11 to 12. Based on the deflection analysis, the pavement is structurally deficient by up to 1 inch of HMA. For this pavement, PEI is providing recommendations for overlaying with HMA and RHMA, milling and replacement, partial depth recycling (PDR), full depth reclamation (FDR) and reconstruction with Full Depth HMA or HMA over aggregate base. For overlaying and milling and replacement, PEI eliminated two data points from the calculation for the northbound #1 lane because they were unusually high. These pavement areas will require removal and replacement. PEI can assist the City in identifying these areas if overlay or milling and replacement alternatives are chosen. See the attached data sheets for the locations of the high deflections. RECOMMENDATIONS Overlay Options HMA We recommend 10-inch pavement repairs of base failures, placing a 1-1/4-inch HMA leveling course, pavement fabric and a 2-1/4-inch HMA overlay. RHMA We recommend 10-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course and a 2-1/4-inch RHMA overlay.

Some sections of pavement have limited cracking. The pavement from the change of pavement north of Bridge Street to Los Osos Valley Road exhibits slight raveling, block shrinkage and areas alligator cracking. Some areas of alligator cracking have progressed to base failure. ANALYSIS The existing pavement consists of 2-1/2 to 14 inches of asphalt concrete over 0 to 22 inches of aggregate base. There are several locations where PCC pavement was encountered. The PCC pavement varied from 7 to 14 inches. There is pavement fabric located approximately 2 inches below the asphalt surface. The native soil is a brown clay with R-values ranging from 10 to 13. Based on the deflection analysis, the pavement is structurally adequate. For this pavement, PEI is providing recommendations for overlaying with RHMA, milling and replacement, and reconstruction with Full Depth HMA or HMA over aggregate base. Overlaying with HMA is not recommended because of the high reflective cracking criteria. Partial depth recycling (PDR) and full depth reclamation (FDR) are not recommended because of the existing PCC layer.

RHMA We recommend 10-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course and a 2-1/2-inch RHMA overlay. The pavement should be evaluated for the base failures present. If the amount of base failure exceeds 10%, then placing overlays may not be cost effective. Milling and Replacement Option HMA We recommend milling off 3 inches of the existing pavement, 8-inch pavement repairs of base failures, placing a 1-inch HMA leveling course, pavement fabric and a 2-inch HMA overlay. RHMA We recommend milling off 2-1/2 inches of the existing pavement, 9-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course and a 2-inch RHMA overlay. At the locations where there is PCC pavement is located under the existing asphalt concrete layer, the milling operation may encounter the top of the PCC layer. Partial Depth Recycling Option (PDR) Partial Depth Recycling (PDR) is not recommended because of the thinner existing pavement section where the PCC pavement is located. FDR Option FDR is not recommended because the areas with PCC cannot be constructed with FDR. Reconstruction Options Full Depth HMA We recommend removing to a depth of 12-1/2 inches and placing 12-1/2 inches of HMA in 5 lifts. There are a few locations where the existing asphalt concrete over PCC pavement exceeds 12- 1/2 inches. In these locations, aggregate base should be used to bring the grade up to 12-1/2 inches below finish grade after removing the pavement section. HMA over Aggregate Base We recommend removing to a depth of 20-1/2 inches, installing a SEG fabric, placing 15 inches of aggregate base and 5-1/2 inches of HMA in 2 lifts. Page 532 of 829 Deflection and Structural Summary Project No. 220205 2023 Arterial Pavement Improvement Project Client: City of San Luis Obispo Both reconstruction alternatives could develop unstable grade from construction traffic during the construction process. Stabilization allowances should be included if one of these alternatives is chosen. As previously discussed in the report, rehabilitation alternatives may have different anticipated service lives. The design engineer should evaluate each alternative based on cost, constructability, and impact on the public.

Some areas of alligator cracking have progressed to base failure in the wheel tracks. Previous maintenance includes utility repairs and slurry sealing. The slurry seal is in poor condition. The pavement from Buchon Street to Lizzie Street has a previous slurry seal that is in poor condition. The section from Lizzie Street to Laurel Lane has a more recent slurry seal that is delaminating in some areas. The base failure in the wheel tracks is more prevalent from Lizzie Street to Laurel Lane. 7 WB2 – 3,420 feet north of Laurel Lane 10 Yes - 11 - 8 WB1 – 3,970 feet north of Laurel Lane 10-1/2 Yes - 8 11 9 WB2 – 4,450 feet north of Laurel Lane 9 Yes - 9 - 10 WB1 – 4,975 feet north of Laurel Lane 9 Yes - 9 11 11 WB2 – 5,500 feet north of Laurel Lane 10 No - 12 - 12 WB1 – 5,950 feet north of Laurel Lane 10-1/2 Yes - 7 12 13 WB1 – 6,450 feet north of Laurel Lane 5 Yes 8 5-1/2 - Direction Traffic Index (TI) Tolerable 80th Percentile HMA Overlay Requirement (Inches) EB1 8.5 15.0 10.4 0 EB2 8.5 15.0 16.8 1/4 WB1 8.5 15.0 9.6 0 WB2 8.5 15.0 11.4 0 HMA Overlay Requirement (Inches)* Pavement Fabric Required (Yes or No) 3-1/4 Yes Page 579 of 829 Deflection and Structural Summary Project No. 220205 2023 Arterial Pavement Improvement Project Client: City of San Luis Obispo ANALYSIS The existing pavement consists of 9 to 15 inches of asphalt concrete over 0 to 16 inches of aggregate base. One core location in the westbound lane had PCC under the asphalt concrete. There is pavement fabric located approximately 2-1/2 inches below the asphalt surface. The native soil is a brown clay with R-values ranging from 11 to 14. Based on the deflection analysis, the pavement is slightly structurally deficient in the eastbound #2 lane by 1/4 inches of HMA. For this pavement, PEI is providing recommendations for overlaying with HMA and RHMA, milling and replacement and partial depth recycling (PDR), full depth reclamation (FDR) and reconstruction with Full Depth HMA or HMA over aggregate base. RECOMMENDATIONS Overlay Options HMA We recommend 10-inch pavement repairs of base failures and placing a 1-1/4-inch HMA leveling course, pavement fabric and a 2-inch HMA overlay. RHMA We recommend 10-inch pavement repairs of base failures and placing a 1-inch HMA leveling course and a 2-inch RHMA overlay. The pavement should be evaluated for the base failures present. If the amount of base failure exceeds 10%, then placing overlays may not be cost effective. Milling and Replacement Option HMA We recommend milling off 2-1/2 inches of the existing pavement, 8-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course, pavement fabric and a 2-inch HMA overlay. RHMA We recommend milling off 2-1/2 inches of the existing pavement, 8-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course and a 2-inch RHMA overlay. Partial Depth Recycling Option (PDR) We recommend milling off 2-1/2 inches of the existing pavement, Partial Depth Recycling (with Emulsified Asphalt or Foamed Asphalt) to a depth of 3 inches, 8-inch pavement repairs of base failures and placing a 2-1/2 -inch RHMA overlay. Page 580 of 829 Deflection and Structural Summary Project No. 220205 2023 Arterial Pavement Improvement Project Client: City of San Luis Obispo FDR Option We recommend uniformly pulverizing 16 inches of existing asphalt concrete, aggregate base, and native soil, removing 7 inches of pulverized material, treating the remaining pulverized material and native soil with cement/lime to a depth of 14 inches and placing 7 inches of new HMA in 3 lifts. This recommendation is based on an unconfined compressive strength (UCS) of 300 psi. There is one location where the existing asphalt concrete is over PCC pavement. The PCC pavement will require removal and replacement with aggregate base. Reconstruction Options Full Depth HMA We recommend removing to a depth of 12-1/2 inches and placing 12-1/2 inches of HMA in 5 lifts. HMA over Aggregate Base We recommend removing to a depth of 20-1/2 inches, installing a SEG, placing 15 inches of aggregate base and 5-1/2 inches of HMA in 2 lifts. Both reconstruction alternatives could develop unstable grade from construction traffic during the construction process. Stabilization allowances should be included if one of these alternatives is chosen. As previously discussed in the report, rehabilitation alternatives may have different anticipated service lives. The design engineer should evaluate each alternative based on cost, constructability, and impact on the public.

Base failure is developing in the cul-de- sac. Previous maintenance includes slurry sealing. The slurry seal is in poor condition. ANALYSIS The existing pavement consists of 2-1/4 to 2-1/2 inches of asphalt concrete over 7-1/2 to 8 inches of aggregate base. PEI could not identify if pavement fabric was present in the asphalt concrete layer. The native soil is a brown clay with an R-value of 11. Based on the deflection analysis, the pavement is structurally deficient by up to 2 inches of HMA. For this pavement, PEI is providing recommendations for overlaying with HMA and RHMA, full depth reclamation (FDR) and reconstruction with Full Depth HMA or HMA over aggregate base.

RECOMMENDATIONS Overlay Options HMA We recommend 4-inch pavement repairs of base failures and placing a 2-inch HMA overlay. RHMA We recommend 4-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course and a 2-inch RHMA overlay. The pavement should be evaluated for the base failures present. If the amount of base failure exceeds 10%, then placing overlays may not be cost effective. Milling and Replacement Option Milling and replacement is not recommended because of the thinner existing pavement section. Partial Depth Recycling Option (PDR) Partial Depth Recycling (PDR) is not recommended because of the thinner existing pavement section. FDR Option We recommend uniformly pulverizing 12 inches of existing asphalt concrete, aggregate base, and native soil, removing 4 inches of pulverized material, treating the remaining pulverized material and native soil with cement/lime to a depth of 8 inches and placing 4 inches of new HMA in 2 lifts. This recommendation is based on an unconfined compressive strength (UCS) of 300 psi. Reconstruction Options Full Depth HMA We recommend removing to a depth of 8 inches and placing 8 inches of HMA in 3 to 4 lifts. HMA over Aggregate Base We recommend removing to a depth of 12 inches, installing a SEG fabric, placing 9 inches of aggregate base and 3 inches of HMA in 2 lifts. Both reconstruction alternatives could develop unstable grade from construction traffic during the construction process. Stabilization allowances should be included if one of these alternatives is chosen. As previously discussed in the report, rehabilitation alternatives may have different anticipated service lives. The design engineer should evaluate each alternative based on cost, constructability, and impact on the public.

PEI could not identify if pavement fabric was present in the asphalt concrete layer. The native soil is a brown clay with an R-value of 16.

For this pavement, PEI is providing recommendations for overlaying with RHMA, milling and replacement, partial depth recycling (PDR), full depth reclamation (FDR) and reconstruction with Full Depth HMA or HMA over aggregate base. Overlaying with HMA is not recommended because of the thicker overlay required to meet reflective cracking criteria. RECOMMENDATIONS Overlay Options HMA Overlaying with HMA is not recommended because of the thicker overlay required to meet reflective cracking criteria. RHMA We recommend 10-inch pavement repairs of base failures, placing a 1-inch HMA leveling course and a 2-inch RHMA overlay. The pavement should be evaluated for the base failures present. If the amount of base failure exceeds 10%, then placing overlays may not be cost effective. Milling and Replacement Option HMA We recommend milling off 3 inches of the existing pavement, 7-inch pavement repairs of base failures, placing a 1-inch HMA leveling course, pavement fabric and a 2-inch HMA overlay. RHMA We recommend milling off 3 inches of the existing pavement, 7-inch pavement repairs of base failures, placing a 1-inch HMA leveling course and a 2-inch RHMA overlay. Partial Depth Recycling Option (PDR) We recommend milling off 2-1/2 inches of the existing pavement, Partial Depth Recycling (with Emulsified Asphalt or Foamed Asphalt) to a depth of 3 inches, 7-inch pavement repairs of base failures and placing a 2-1/2-inch RHMA overlay. FDR Option We recommend uniformly pulverizing 16 inches of existing asphalt concrete, aggregate base, and native soil, removing 6-1/2 inches of pulverized material, treating the remaining pulverized material and native soil with cement to a depth of 13 inches and placing 6-1/2 inches of new Page 627 of 829 Deflection and Structural Summary Project No. 220205 2023 Arterial Pavement Improvement Project Client: City of San Luis Obispo HMA in 3 lifts. This recommendation is based on an unconfined compressive strength (UCS) of 300 psi. Reconstruction Options Full Depth HMA We recommend removing to a depth of 12 inches and placing 12 inches of HMA in 4 to 5 lifts. HMA over Aggregate Base We recommend removing to a depth of 20-1/2 inches, installing a SEG, placing 15 inches of aggregate base and 5-1/2 inches of HMA in 2 lifts.

PEI could not identify if pavement fabric was present in the asphalt concrete layer. The native soil is a brown clay with R-values ranging from 10 to 12. Based on the deflection analysis, the pavement is structurally deficient by up to 5-1/2-inches of HMA. For this pavement, PEI is providing recommendations for full depth reclamation (FDR) and reconstruction with Full Depth HMA or HMA over aggregate base. Overlaying, milling and replacement and partial depth recycling (PDR) are not recommended because of the thinner existing asphalt concrete layer and structural deficiency. RECOMMENDATIONS Overlay Options Overlaying is not recommended because of the structural deficiency. Milling and Replacement Option Milling and replacement is not recommended because of the thinner existing asphalt concrete layer and structural deficiency. Partial Depth Recycling Option (PDR) Partial depth recycling (PDR) is not recommended because of the structural deficiency. FDR Option We recommend uniformly pulverizing 16 inches of existing asphalt concrete, aggregate base, and native soil, removing 7 inches of pulverized material, treating the remaining pulverized material and native soil with cement a depth of 14 inches and placing 7 inches of new HMA in 3 lifts. This recommendation is based on an unconfined compressive strength (UCS) of 300 psi. Reconstruction Options Full Depth HMA We recommend removing to a depth of 12-1/2 inches and placing 12-1/2 inches of HMA in 5 lifts. HMA over Aggregate Base We recommend removing to a depth of 20-1/2 inches, installing a SEG, placing 15 inches of aggregate base and 5-1/2 inches of HMA in 2 lifts. Both reconstruction alternatives could develop unstable grade from construction traffic during the construction process. Stabilization allowances should be included if one of these alternatives is chosen.

ANALYSIS The existing pavement consists of 3-1/2 to 8 inches of asphalt concrete over 3 to 18 inches of aggregate base. PEI could not identify if pavement fabric was present in the asphalt concrete layer. The native soil is a brown clay with R-values ranging from 10 to 12.

Some areas of alligator cracking have progressed to base failure in the wheel tracks.

PEI could not identify if pavement fabric was present in the asphalt concrete layer. The native soil is a brown clay with R-values ranging from 10 to 13. Based on the deflection analysis, the pavement is structurally deficient by up to 2-1/4-inches of HMA. For this pavement, PEI is providing recommendations for overlaying with HMA and RHMA, full depth reclamation (FDR) and reconstruction with Full Depth HMA or HMA over aggregate base. Milling and replacement and partial depth recycling (PDR) are not recommended because of the structural deficiency. RECOMMENDATIONS Overlay Options HMA We recommend 8-inch pavement repairs of base failures and placing a 1-inch HMA leveling course, pavement fabric and 2-1/4-inch HMA overlay. RHMA We recommend 8-inch pavement repairs of base failures, placing a 1/2-inch HMA leveling course and a 2-inch RHMA overlay. The pavement should be evaluated for the base failures present. If the amount of base failure exceeds 10%, then placing overlays may not be cost effective. Milling and Replacement Option Milling and replacement is not recommended because of the structural deficiency. Partial Depth Recycling Option (PDR) Partial Depth Recycling is not recommended because of the structural deficiency. FDR Option We recommend uniformly pulverizing 16 inches of existing asphalt concrete, aggregate base, and native soil, removing 7 inches of pulverized material, treating the remaining pulverized material and native soil with cement/lime to a depth of 14 inches and placing 7 inches of new HMA in 3 lifts. This recommendation is based on an unconfined compressive strength (UCS) of 300 psi. Reconstruction Options Full Depth HMA We recommend removing to a depth of 12-1/2 inches and placing 12-1/2 inches of HMA in 5 lifts. Page 687 of 829 Deflection and Structural Summary Project No. 220205 2023 Arterial Pavement Improvement Project Client: City of San Luis Obispo HMA over Aggregate Base We recommend removing to a depth of 20-1/2 inches, installing a SEG fabric, placing 15 inches of aggregate base and 5-1/2 inches of HMA in 2 lifts. Both reconstruction alternatives could develop unstable grade from construction traffic during the construction process. Stabilization allowances should be included if one of these alternatives is chosen. As previously discussed in the report, rehabilitation alternatives may have different anticipated service lives. The design engineer should evaluate each alternative based on cost, constructability, and impact on the public.
