Use caution when opening attachments or links. Dear Ms. Chandler, I hope this email finds you well. I am writing to inquire if there are any specific requirements or procedures that the County Public Health Department needs from the City of San Luis Obispo regarding soil remediation on a construction site. Recently, we conducted shallow soil sampling on one of the City’s project sites and identified a non-uniform distribution of lead in the samples. We have already contacted the Air Pollution Control District (APCD) and will provide them with all the necessary information as required. Additionally, we have engaged the services of an environmental compliance coordinator who is currently working on developing a comprehensive soil monitoring plan for when we commence grading activities on the site. We anticipate that the grading and soil manipulation work will begin in September. As part of our commitment to ensuring safety and compliance, we are strictly adhering to all Cal OSHA requirements. All our employees who will be present on-site will be HAZWOPER trained out of an abundance of caution. Considering the potential environmental impact and the significance of soil remediation, we would greatly appreciate any guidance or instructions that the County Public Health Department may have for us. It is crucial for us to align our remediation efforts with the County's regulations and protocols. If there are any specific documentation, permits, or procedures that we need to comply with, kindly inform us at your earliest convenience. We are committed to addressing this issue effectively and ensuring the safety of the environment and surrounding community. Thank you in advance for your assistance. We look forward to receiving your guidance and working together to address this matter. Please do not hesitate to reach out if you require any additional information or have any questions.

Public Resources Code Section 21081.6(a)(1) requires that a Lead Agency adopt an MMRP before approving a project in order to mitigate or avoid significant impacts that have been identified in an Environmental Impact Report (EIR). The purpose of the MMRP is to ensure that the required mitigation measures identified in the EIR are implemented as part of the overall project development process. In addition to ensuring implementation of mitigation measures, the MMRP provides guidance to agency staff and decision-makers during project implementation, and identifies the need for enforcement action before irreversible environmental damage occurs. The following table summarizes the mitigation measures for each issue area identified in the EIR for the project. Specifically, the table identifies each mitigation measure; the action required for the measure to be implemented; the time at which the monitoring is to occur; the monitoring conditions; and the agency or party responsible for ensuring that the monitoring is performed. In addition, the table includes columns for compliance verification.

(Rincon) has prepared this report presenting the findings of a soil assessment performed at 609 Palm Street in San Luis Obispo, California (Vicinity Map, Figure 1). The soil assessment was performed for compliance with HAZ-1 of the Cultural Arts District Parking Structure Project (Project) Mitigation, Monitoring, and Reporting Program (MMRP). The following sections describe the Project and site background, soil assessment methodology, screening criteria, analytical findings of the soil assessment, and conclusions and recommendations. Background Project Description The site is currently developed with a surface level parking lot divided by a sloped garden planter, creating an approximate 4 to 6-foot height variation between the upper and lower parking sections (Figure 2). The area consists of overhead power lines, mature trees, and underground utilities surrounding the perimeter. The Project includes the construction of a multi -level parking structure in roughly the same area as the existing surface parking lot at the corner of Palm and Nipomo streets, and construction of a Repertory Theatre structure to the southeast towards Monterey Street. The portion of the Project site that was included in the soil assessment was the planned parking structure at the corner of Palm and Nipomo Streets. Our understanding of Project earthwork was based on review of the April 20, 2020, Preliminary Palm and Nipomo Phase 1 On-Site Improvement Plans prepared by RRM Design Group. The existing parking lot and structures will be demolished, and then excavated to maximum depths of 18 feet. Raw cut is estimated as 15,300 cubic yards. In the assessment area at 609 Palm Street, the Project excavation depths will be between 2 and 6 feet (RRM 2020). Site Setting The site slopes downward from southeast to northwest with a maximum elevation of 203 feet above mean sea level (AMSL) at the southeast corner, and minimum elevation of 190 feet AMSL at the northwest corner (Earth Systems Pacific, 2011). APPENDIX D - SOIL ASSESSMENT REPORT 157 City of San Luis Obispo Cultural Arts District Parking Structure Project 609 Palm Street, San Luis Obispo, California Page 2 The site is characterized by alluvial sand and gravel from surrounding valley areas and is underlain by Franciscan Assemblage, primarily consisting of greywacke sandstone and metavolcanic rock . This metavolcanic rock often has high levels of iron, nickel, chromium, and magnesium (Earth Systems Pacific 2011). Alluvium observed during an assessment performed by Kleinfelder contained inconsistent zones of sandy clay, clay, and clayey gravel underlain by weak to moderately strong shale bedrock (Kleinfelder 2005). Groundwater was first encountered at approximately 30 feet below ground surface (bgs) in one boring advanced by Kleinfelder in 2005 and between 24 and 30 feet bgs in four borings advanced by Earth Systems Pacific at the site in 2011. Site History A June 8, 2005, report titled Constraints Level Environmental and Geotechnical Assessment (report) prepared by Kleinfelder describes previous site uses, areas of concern for soil impacts, and soil assessment findings. Except for 960 Nipomo Street (address changed to 609 Palm Street in 1992), most of the site appears to have been residential use prior to development as a parking lot. A welding shop and automotive repair station were previously located at 960 Nipomo Street. The onsite parking lot development appears to occur after 1998. The report included documents from Cleath and Associates (Cleath) and San Luis Obispo (SLO) City Fire Department that describe the following potential areas of concern at 960 Nipomo/609 Palm: Hydraulic lift. A hydraulic lift was removed in the early 1990s. No evidence of soil discoloration and odor were reported by Cleath in the excavation and soil stockpile (Cleath 1992). Oil-stained surface soil was identified near the northeast corner of the building at the garage entrance. During an inspection performed by Cleath in 1992, the area of oil-stained soil was no longer evident (Cleath 1992). Dry well. A dry well approximately 15 feet bgs was observed. A 1991 memorandum from Michael Smith, SLO City Hazardous Materials Inspector, recommends destruction per County Health Department standards (SLO 1991). C oncrete pit (mechanics pit). A memorandum from Michael Smith, SLO City Hazardous Materials Inspector, indicates the concrete pit was found to be sound, with the concrete floor, and sides containing no indications of petroleum spillage (SLO 1991). Fill pipe. A fill pipe likely used as modified sewer clean-out was observed (SLO 1991). Kleinfelder advanced three borings at the site with one of the borings being advanced at 960 Nipomo Street/609 Palm. One soil sample from each boring, collected at 5 feet bgs, was analyzed for volatile organic compounds (VOCs) using United States Environmental Protection Agency (EPA) Method 8260, semi-volatile organic compounds (SVOCs) using EPA Method 8270, and cadmium, chromium, lead, nickel, and zinc using EPA Method 6010. VOCs and SVOCs were not detected above laboratory reporting limits in the soil samples. Chromium and nickel were detected at total concentrations exceeding ten times soluble threshold limit concentration (STLC) levels and were analyzed for soluble chromium and soluble nickel using deionized water waste extraction test (DI-WET). Leachable chromium and nickel were detected at concentrations below STLC levels. DI-WET uses deionized water for metal extraction. If soil is to be disposed at a landfill, STLC analysis using WET with acid extraction is required for total metals detected at concentrations exceeding APPENDIX D - SOIL ASSESSMENT REPORT 158 City of San Luis Obispo Cultural Arts District Parking Structure Project 609 Palm Street, San Luis Obispo, California Page 3 ten times STLC. The current assessment performed by Rincon and described in this report, analyzed metals by WET as warranted and described in the Results section. Five borings were additionally advanced at the site by Earth Systems Pacific in 2011. Metals were detected in the soil samples at similar concentrations to the 2005 Kleinfelder assessment. Total petroleum hydrocarbons (TPH) in the oil range were detected at 3,700 milligrams per kilogram (mg/kg) in the sample collected from 3 feet bgs in boring B-6, and at 140 mg/kg in the sample collected at 4 feet bgs in boring B-4. TPH was not detected or detected at low concentrations in the other analyzed soil samples. Methodology Boring locations were marked in the field using a GPS device with submeter accuracy (Figure 3). A hand auger was utilized on May 26, 2022, to continuously core five soil borings. Soil samples were collected at 2 feet bgs from borings HA1 to HA5, and 5 feet bgs from HA3 and HA4. When the target sampling depth was reached, a slide hammer sampler was utilized to collect discrete soil samples in 6-inch long by 2- inch diameter stainless steel sleeves. A second mobilization was subsequently conducted on July 6, 2022. Additional characterization of constituents detected, as well as the need to resample locations requiring additional solubility analysis (due to inadvertent disposal of samples by the analytical laboratory) was conducted. A Geoprobe® was utilized by Oilfield Environmental and Compliance (OEC) under direction of Rincon to advance five borings to 2 feet bgs . Soil samples were collected from the borings (HA6 to HA10) at 2 feet bgs . Borings were continuously cored by hydraulically driving a two-inch diameter sampling rod into the ground. The macro -core sampler consists of a two-inch diameter tube containing an acetate sleeve liner. By advancing this sampler into the soil, soil was forced into the opening of the sampling tube and a sample was obtained. The designated sampling section (6-inch) length was cut and retained for laboratory analysis. All samples retained were sealed with Teflon sheets, capped, labeled, and stored in a cooler, chilled to approximately 4 degrees Celsius, pending delivery to the analytical laboratory. Soil sample collection was in conformance with the current version of the United States EPA, SW-846 guidance document – Test Methods for Evaluating Solid Waste. The samples were couriered to the analytical laboratory using chain-of-custody protocol. Unretained soil recovered near the sample depths was used to field screen for VOCs, total lead, and to classify the soils. Soil was placed in a zip lock baggie and allowed to volatilize. After sufficient time, the baggie was slightly opened, and the photoionization detector (PID) probe tip was placed within one- eighth inch of the soil inside the baggie. Prior to testing, the PID was calibrated to an isobutylene standard. Soil was also field screened for lead with a x-ray fluorescence (XRF) analyzer. Observations made in the field, including soil classification per the Unified Soil Classification System, a description of any debris, discoloration, odors, PID readings, and XRF measurements were documented on boring logs completed for each location (Appendix A). Following collection of soil samples, all equipment was washed in a non-phosphate detergent solution and double rinsed with water. Borings were backfilled with a concrete bentonite slurry. Asphalt patch was added to the top several inches of the borings to attain a flush paved finish. Soil cuttings and APPENDIX D - SOIL ASSESSMENT REPORT 159 City of San Luis Obispo Cultural Arts District Parking Structure Project 609 Palm Street, San Luis Obispo, California Page 4 decontamination water were properly stored onsite in one labeled Department of Transportation 55- gallon drum pending receipt of analytical data. Sampling was performed under the oversight of a California Professional Geologist. Sample Analysis The soil samples collected on May 26, 2022, were analyzed for the following:  Polyaromatic hydrocarbons (PAHs) using EPA Method 8270C Selected Ion Monitoring (SIM) mode  Full range TPH using EPA Method 8015M  Metals using EPA Method 6010B/7471A  VOCs using EPA Method 8260B Soil samples collected on July 6, 2022, were analyzed for the following:  Two soil samples (HA8-2 and HA9-2) were analyzed for PAHs using EPA Method 8270C SIM  Five soil samples (HA6-2 to HA10-2) were analyzed for total chromium, STLC chromium, and toxicity characteristic leaching procedure (TCLP) chromium using EPA Method 6010B  Two soil samples (HA5-2 and HA6-2) were analyzed for total lead and STLC lead using EPA Method 6010B  One soil sample (HA6-2) was analyzed for total nickel and STLC nickel using EPA Method 6010B Screening Criteria The site is within the jurisdictional area of the Central Coast Regional Water Quality Control Board (CCRWQCB). The CCRWQCB generally uses Environmental Screening Levels (ESLs ) developed by the San Francisco Bay RWQCB. ESLs are conservative concentration thresholds designed to be protective of the environment and human health. Under most circumstances, the presence of a chemical in soil, soil vapor, groundwater, or ambient air at concentrations below the corresponding ESL can be assumed to not pose a significant, long term (chronic) threat to human health and the environment. Additional evaluation is generally necessary at sites where a chemical is detected at concentrations above the corresponding ESL. Active remediation may or may not be required depending on site specific conditions and considerations. The constituents detected in soil samples were evaluated with consideration to the following:  Were any ESLs exceeded?  Is additional delineation (lateral or vertical) warranted based on the ESLs?  Will remediation be required prior to or during construction?  Will special handling and disposal of impacted soil be required during construction? Constituents detected during the Rincon assessment were compared to the following ESLs:  Tier 1 ESL: Acceptable for most land uses  Commercial/Industrial Sites: Based on direct contact at commercial and industrial sites. The lower value of carcinogenic or non-carcinogenic risk was used as the screening level. APPENDIX D - SOIL ASSESSMENT REPORT 160 City of San Luis Obispo Cultural Arts District Parking Structure Project 609 Palm Street, San Luis Obispo, California Page 5  Construction Worker: Based on direct contact with soil by a construction worker. The lower value of carcinogenic or non-carcinogenic risk was used as the screening level.  Leaching: Based on potential to leach to groundwater. The lower value for drinking water was used as the screening level. The following describes additional constituent specific screening criteria: PAHs In addition to compari ng PAHs to ESLs, a toxicity equivalency factor (TEF) was used to convert concentrations of carcinogenic PAHs to an equivalent concentration of benzo(a)pyrene (BaP). The BaP toxicity equivalent (TE) was used to evaluate cancer risk posed by these PAHs from oral exposure. The seven carcinogenic PAHs and their respective TEFs are listed below: Toxicity Equivalency Factors for Carcinogenic PAHs PAH Compound TEF Benzo(a)pyrene 1.0 Benz(a)anthracene 0.1 Benzo(b)fluoranthene 0.1 Benzo(k)fluoranthene 0.01 Chrysene 0.001 Dibenz(a,h)anthracene 1.0 Indeno(1,2,3-c,d)pyrene 0.1 TPH TPH was compared to ESLs. ESLs use the following carbon ranges to differentiate the different types of hydrocarbons: gasoline range organics are in the carbon 4 (C4) to C12 range, diesel range organics are in the C13 to C22 range, and oil range organics are in the C23 to C40 range. The analytical laboratory (OEC) distinguishes the type of hydrocarbons by the same carbon ranges as ESLs. VOCs VOCs were compared to ESLs. Metals Metals were compared to ESLs, background concentrations, and hazardous waste determination criteria. Typical background concentrations for metals in soil in California are as referenced in Kearny Foundation of Soil Science, Division of Agriculture and Natural Resources, University of California, March 1996. Hazardous waste determination, for soil disposal purposes, included comparing metals to the following screening criteria:  Total metal concentrations were compared to the respective total threshold limit concentration (TTLC), to evaluate whether the soil is a California non- Resource Conservation and Recovery Act (RCRA) waste APPENDIX D - SOIL ASSESSMENT REPORT 161 City of San Luis Obispo Cultural Arts District Parking Structure Project 609 Palm Street, San Luis Obispo, California Page 6  STLC metal concentrations were compared to STLC thresholds to evaluate whether the soil is a non- RCRA waste  TCLP metal concentrations were compared to TCLP thresholds to evaluate whether the soil is a RCRA waste Results No soil discoloration or odors were noted that may be indicative of impacted soil collected from the borings. Soil encountered in the borings generally consisted of medium grained silty sand with clay and gravel. Groundwater was not encountered in the borings. Soil analytical results are summarized on Tables 1 through 3. A complete list of the analyzed constituents is included in the laboratory analytical reports in Appendix B. TPH TPH was not detected above method detection limits in any of the soil samples (Table 1) collected by Rincon. TPH was detected during the previous 2011 assessment at boring locations B-4 and B-6. Rincon deliberately located boring HA-4 near B-6 and boring HA-8 near B-4 based on the results of the 2011 assessment. Although TPH was not detected during Rincon’s assessment, it is possible there are isolated areas containing TPH at concentrations exceeding screening criteria. VOCs VOCs were not detected or detected at very low concentrations by the PID. The highest PID measurement was 10.3 parts per million by volume (ppmv) in boring HA5. As summarized on Table 1, the only VOC detected in the soil samples was 0.015 micrograms per kilogram (µg/kg) 4-isopropyl toluene in soil sample HA5-2. An ESL has not been developed for 4-isopropyl toluene. PAHS PAHs were detected above ESLs in one (HA1-2) of the nine soil samples (Table 2). The lateral and vertical extent of BaP and BaP TE detected in HA1-2 was delineated based on soil samples collected from adjacent borings. Metals As summarized on Table 3, the following metals exceeded screening levels:  Arsenic, lead, nickel, vanadium, and zinc exceeded ESLs  Chromium, lead, and nickel were detected at concentrations that warrant soluble analyses for disposal purposes Metals detected at concentrations within background levels generally do not require additional assessment or remediation. However, ESLs and hazardous waste determination levels for lead are below the upper range of background levels for lead in Cal ifornia soil. Arsenic, lead, nickel, and vanadium were detected above ESLs but within background levels for California soils (Kearny 1996). APPENDIX D - SOIL ASSESSMENT REPORT 162 City of San Luis Obispo Cultural Arts District Parking Structure Project 609 Palm Street, San Luis Obispo, California Page 7 Zinc was detected in HA5-2 at 460 mg/kg which exceeds the Tier 1 ESL of 340 mg/kg, which is based on terrestrial risk. ESLs for direct contact of zinc in soil at commercial sites and by construction workers are 350,000 mg/kg and 110,000 mg/kg, respectively. The zinc detected in HA5-2 is well below these ESLs. Chromium, lead, and nickel were detected at concentrations warranting STLC analysis and chromium also warranted TCLP analysis for disposal purposes. STLC and TCLP detections did not exceed hazardous waste thresholds. Chromium was detected at similar concentrations in all of the soil samples and is likely representative of background chromium in site soil. Conclusions PAHs detected in HA1-2 at concentrations exceeding ESLs are delineated by adjacent samples. Certain metals were detected at concentrations exceeding ESLs and above thresholds that warrant additional hazardous waste determination analyses. TPH was not detected and only one low detection of a VOC was reported. Recommendations Soil remediation does not appear to be warranted based on the findings of this soil assessment. Soil excavated during Project construction should be properly managed and its use may be restricted based on the analytical data. Soil at HA1-2 could be re-used onsite if it is re-used at the same location it was removed from. If soil from the location of HA1-2 is to be removed from the site, it should be properly disposed. Other site soil may not be suitable for offsite re-use due to the elevated concentrations of certain metals. A soil management plan is recommended to be developed and used for the Project, and this report submitted to an oversight agency for review. It appears that certain subsurface features such as the mechanics pit and dry well may remain at the site. If encountered, soil impacts may be associated with the features. The soil management plan should describe the methodology for performing soil characterization during Project construction, as warranted. To avoid construction delays, required permits and notifications for excavation of impacted soil should be completed prior to commencing Project earthwork. It is anticipated that the City’s annual permit with the SLO County Air Pollution Co ntrol District will cover the impacted soil management activities .

Use caution when deciding to open attachments, click links, or respond. Hey Ben and Madeline, Spoke with Edwards this afternoon and they confirmed that Coastal and PARK will continue with demolition work on Tuesday 5/16. Coastal will have a couple of employees onsite Monday 5/15 to install the additional BMPs we discussed during our meeting. They should be onsite around 9am. We are coordinating with Edwards for the Lead Awareness Training that we will need to attend and will update Anthony and Jake (Arborists) as soon as we get a confirmed time. Below are the talking points I covered with Edwards and Coastal this afternoon, and attached is PARKs plan with the edits Madeline and I spoke about on the phone this afternoon.  City notified Kitchell that demolition work for footings, tree roots, grubbing and all other dirt disturbing activities can proceed according to PARKs plan. o See attached comments.  PreDemolition Lead Awareness Talk o Before Demolition begins on Tuesday o Need to include City Employees, Arborists, and Kitchell  BMPs o Silt fence will be needed around entire worksites, and storm drains should be covered. o City Standard documents have details  Post Demolition – Mulch Coverage for site o Site will need to have mulch coverage as soon as all demolition work is finished. o Kitchell to follow up with City on if mulch will be provided by the city.  Clarification on where signage will be located. o Is it inside the fenced area for construction personnel or will there be signage on the fence for the public.  All demolished materials that were in contact with Non-RCRA soils will need to have a disclosure to the recycling facility or landfill.  Cost Impacts o Please track impacts on T&M tickets for Phase 1B.1  Phase 1B.2 (Asphalt removal) o Kitchell will be following up with the City for a path forward and will keep the team updated. Thanks and have a great weekend!

In the event there is a spill, all materials and/or waste shall be properly cleaned up immediately, and secured to prevent contamination of surrounding environments. 11.0. Emergency Response a. In the event of a medical emergency involving personal injury or illness, a CPR-trained person should render first aid, and Emergency Medical Services shall be summoned via cell phone. Personnel will be decontaminated (if injury/illness occurs in a contaminated area and PPE is being utilized) to the extent possible without further injury. Lifesaving and first aid procedures take priority over personal decontamination efforts. b. Emergency phone numbers shall be posted at the jobsite, and evacuation procedures shall be discussed with the crew at the tailgate safety meeting. c. PARC will utilize 911 for all emergencies. In case of emergency, the site foreman shall immediately secure the area, make the appropriate emergency calls, provide location and appropriate information, and secure safe site access for emergency response traffic. The site foreman will have a cell phone available at all times. Appendix A Definitions a. Action Level (AL) – Employee exposure, without regard to the use of respirators, to an airborne concentration of lead of 30 micrograms per cubic meter of air (30 g/m3) calculated as an 8-hour time-weighted average (TWA). b. Lead Based Paint-Paint or other surface coatings that contain an amount of lead equal to, or in excess of: i. One milligram per square centimeter ii. Half of one percent (0.5%) by weight (5,000 ppm) c. Permissible Exposure Limit (PEL) - The allowable 8-hour time weighted average concentration of airborne lead the employee may be exposed to without regard to the use of respirators. This value is 50 g/m3 of lead in air or 0.050 mg/m3 of lead in air. d. Regulated Area – Work areas where airborne exposure to lead is at or above the PEL or when work in the area includes tasks listed in 29 CFR 1926.62 paragraph (d)(2). 11 From:Kacsinta, Madeline Sent:Wednesday, May 10, 2023 8:11 AM To:Dustin Merrick Cc:Nelson, Brian Subject:Soil Assessment Report Attachments:D - Project Soil Assessment Report.pdf Hi Dustin, I am trying to get our Cultural Arts District Parking Structure bid ready! Obviously, we have had some recent soil assessment updates. We are working toward getting language into our plans and specs about how the contractor should handle the soil remediation, but I also wanted to check on the soil assessment report that we have in the bid documents as an appendix. Do we need to update this report? I was going to include the map that you provided last Friday, but I didn’t know if you had anything else that we should add or amend. Thanks for your help on this!

Use caution when deciding to open attachments, click links, or respond. Hi Madeline, We have been working with Edwards to update time frames due to the changes. As of this morning Edwards is planning/targeting to have all buildings down by EOW. Below is the rough time frame for the remainder of the week that was discussed with Edwards and Coastal this morning. Today (5/9) - finish building demolition on Palm street structures and clean up of Palm street areas. Remove fence and clear trees for path to 614 Monterey (Adobe) Wednesday (5/10) - Finish site prep and access to 614 Monterey and begin demo, KITCHELL has reached out to RRM arborist(Jake) and they are available to observe demolition in the tree drip zone (rough target of 11am, will update as needed) Thursday (5/11) - finish 614 Monterey and move into demolition of 610 Monterey (corner house). Friday (5/12) - Finish 610 Monterey potentially start on Nipomo street garage unit and general Monterey street properties clean up. We may potentially have the garage or part of 610 Monterey still standing at the end of this week depending on how things progress. I think the bigger concern would be how liability would be transferred from Edwards to SLO Fire as currently the site is under Edwards control. Does SLO fire have a liability release we could share with Edwards to see if it's something they would be comfortable with? That may be a good starting point and then we can see what is available for them once the liability concerns are worked out.

The original cultural resources study (attached) was conducted by Applied Earthworks in 2011. In 2017, the City of SLO conducted SB 18 and AB 52 outreach for the project as part of their EIR. I’m attaching the CR/TCR section of the EIR for your review. I’m happy to share the whole EIR, but it is too big to simply attach. Feel free to let me know if you’d like to see the whole document. Based on the EIR mitigation measures, Rincon developed a mitigation and monitoring plan (attached). As part of that plan, Rincon conducted a series of 35-centimeter-wide shovel test pits throughout the project site. We’re currently drafting the extended Phase I study, and I’d be happy to share it once it’s ready. In the meantime, I can give you initial results of the study now. Of the 25 shovel test pits excavated, all were negative for cultural resources. Modern debris was noted in many of the test pits. While we were doing archaeological testing, we were also conducting soils testing and observed elevated levels of lead. For health and safety purposes, shovel test pits were terminated in any test pit that registered levels of lead that may be considered hazardous. Unfortunately, much of the soils have since been tested and are considered hazardous. Hopefully the documents and my synopsis of the archaeological testing gives you a better idea of the project, but please do not hesitate to reach out if you have any questions. Have a good day!

My name is Madeline Kacsinta, and I am the new project manager for the Cultural Arts District Parking Structure Project in San Luis Obispo. I recently started at the City of SLO and am excited to start working on this project. I understand that you have worked closely with Eric Eldridge in the past, and I have had the opportunity to work hand in hand with him on various projects during my 10 years of experience with the City of Pismo Beach. I am very familiar with projects in archeologically sensitive areas and understand the importance of preserving cultural heritage. I am reaching out to you today to provide you with more information about the Cultural Arts District Parking Structure Project. The news story that you may have heard regarding the project's timeline could have been misleading, and I wanted to clarify that there are multiple phases to the project. Phases 1A and 1B are currently in construction and include the utilities relocations, demolition of the existing buildings, and some site prep work. The majority of Phase 1B will kick off on Monday with the demolition of the first of three existing structures on the property. We are expecting the three buildings to be demoed in May and not start demo on the parking lot until August to give you a better idea of the timeline. The current parking lot will remain open during this downtime before the contractor scrapes the lot in preparation for the Parking Structure, which is going out to bid shortly and is Phase 2 of the project with a separate contractor. The parking structure construction is anticipated to start in September 2023 and is expected to be completed around December 2025. As project manager, I have reviewed the Environmental Impact Report, and Rincon will be on-site as the project's archaeological monitor. They are having a training for all staff on-site on Monday prior to the demolition of any buildings. I understand that on previous phases, the tribe was not requesting to be on-site, but I would be happy for the tribe to be involved moving forward and can keep you informed on the schedule of the project if there are phases in which you might be more interested. If you have any questions or concerns, please do not hesitate to reach out to me. I am happy to meet with you to discuss the project further and insure you are comfortable with the construction project moving forward. Thank you for your time, and I look forward to working with you.

proposed Palm Nipomo Parking Structure Project, alternatives to the project, and the environmental impacts, mitigation measures, and residual impacts associated with the project. City staff prepared an Initial Study and circulated a Notice of Preparation (NOP) for the project on May 1, 2017. The Initial Study identified potentially significant impacts with respect to aesthetics, cultural resources, noise, and transportation and traffic, and this document is an environmental impact report (EIR) that further analyzes those impacts. All other CEQA issue areas were addressed in the Initial Study (Appendix A) and are summarized in Section 5.0, Issues Addressed in the Initial Study.

The following is a summary of the full project description, which is located in Section 2.0, Project Description. The project would involve the removal of an existing 77-space surface parking lot and five residential structures (including detached garage) and construction of an above-ground, five-level parking structure, non-profit theater, and commercial space on a 1.38-acre site located in the city of San Luis Obispo. The parking structure would provide up to 445 parking spaces.1 Main vehicular access to the structure would be provided from Palm Street, with secondary access from Nipomo Street. The theater would entail a three-story structure with a gross floor area of 23,841 square feet 1 The parking structure is undergoing design refinement with respect to the ultimate number of parking spaces. Based on the current design, the structure would provide 410 parking spaces; however, the analysis conservatively assumes a maximum of up to 445 parking spaces would be provided.

This includes the following five alternatives:  Alternative 1. No Project /No Development assumes the project is not approved, that none of the proposed entitlements are implemented, and that no further development would occur on the project site.  Alternative 2. Project Plus Live/Work Units would be the same as the proposed project described above, except the 5,000 square feet of commercial space would be reduced to 2,500 square feet of commercial space and four residential units would be included.  Alternative 3. Parking Structure, Commercial, and Residential would be the same as the preferred project described above, except the theater would be replaced with 22 two-bedroom residential units.  Alternative 4. Historic Resource Preservation would include the parking structure and 5,000 square feet of commercial space, but retain the two houses at 610 and 614 Monterey Street. The theater would not be included as part of this alternative. Alternative 4. The Historic Resource Preservation Alternative would be the environmentally superior alternative, as it would avoid direct impacts to historical resources because the two contributing structures to the Downtown Historic District and the linkage between properties in the district they provide would remain in place. However, aesthetic and noise impacts would remain significant and unavoidable. Alternative 1. No Project/No Development could also be considered environmentally superior to the proposed project because the site would remain as is and it would not result in any significant environmental impacts; however, it would not meet the project objectives. Alternative 2. Project Plus Live/Work Units would result in a similar magnitude of environmental impacts as the proposed project, as buildout would be almost identical. This alternative would not reduce any of the significant and unavoidable impacts. Alternative 3. Parking Structure, Commercial, and Residential would result in a similar magnitude of environmental impacts as the proposed project. The addition of 22 residential units in place of the theater would not result in inferior or superior environmental conditions relative to the proposed project and would not eliminate the significant impacts to historical resources, visual City of San Luis Obispo Palm Nipomo Parking Structure Project 4 character, or from construction noise. Most of the issues addressed in the Initial Study would be the same as the proposed project, with an incremental increase in public services demanded and water/wastewater generated. The complete alternatives analysis is included in Section 7.0, Alternatives. Areas of Concern Pursuant to State CEQA Guidelines § 15123(b)(2), this EIR acknowledges the areas of controversy and issues to be resolved which are known to the City of San Luis Obispo or were raised during the scoping process. An Initial Study and Notice of Preparation (NOP) of an EIR was prepared and circulated for a 30-day agency- and public-review period beginning on May 1, 2017. Several comment letters from members of the public were received in response to the NOP. In addition, an EIR Scoping Meeting was also held at the Planning Commission Meeting on May 10, 2017, and comments on the scope of the EIR were received from members of the public and the City Planning Commissioners. The NOP and Initial Study, and NOP comment letters are included in Appendix A of this EIR. Key issues of concern that were identified in the NOP responses and voiced at the EIR scoping meeting included the following: Comment/Area of Concern EIR Section Where Addressed Impacts on views of Cerro San Luis Obispo 4.1 Aesthetics Size and scale of the project and its aesthetic compatibility with the historical character or surrounding development 4.1 Aesthetics Impacts to historical resources, including adobe on the project site 4.2 Cultural and Tribal Cultural Resources Impacts to tribal cultural resources 4.2 Cultural and Tribal Cultural Resources Increase in operational noise and its impact on sensitive receptors 4.3 Noise Vehicle trips generated by project 4.4 Transportation Pedestrian-vehicle conflicts; pedestrian safety crossing Nipomo Street 4.4 Transportation Induced travel 4.4 Transportation Calculation methodology for greenhouse gas emissions 5.0 Issues Addressed in Initial Study Alternatives to the project 7.0 Alternatives Revisions to the Draft EIR Under the provisions CEQA Section 15088, a 45-day public review period of the Draft EIR is required. The Draft EIR was circulated from December 14, 2017 until March 1, 2018. Each written and verbal comment that the City received is included in Section 9.0, Responses to Comments. Responses to these comments have been prepared to address the environmental concerns raised by the commenters and to indicate where and how the Draft EIR addresses pertinent environmental issues. The Draft EIR and responses to comments collectively comprise the Final EIR for the project. The responses to comments summarize the comment and direct the commenter to the section of the Draft EIR that addresses their comment. In some cases, revisions have been made to the Draft EIR to clarify information, data, or intent, or to make minor typographical corrections or minor working changes. Any changes made to the text of the Draft EIR are noted in the Final EIR as changes from the Draft EIR. Where a comment results in a change to the Draft EIR text, a notation is made in the response indicating that the text is revised. Changes in the Draft EIR text are signified by strikeouts where text is removed and by underline font where text is added. If text is added where Executive Summary Final Environmental Impact Report 5 the font is already bold or underlined, additions are noted using underlined bold font. Revisions were made to the proposed number of theater seats. These changes are shown on page 2 of the Executive Summary and Section 2.5, Project Characteristics. Although the total number of seats increased from 155 to 191, this did not change any of the impacts as project effects were calculated based on building square footage and/or number of employees, which did not change. In addition, a revision was made to the theater footprint shown on Figure 5, Site Plan, based on refinements to the project design. As previously noted, the building square footage did not change and this revision did not change any of the impacts. Summary of Impacts and Mitigation Measures Table 2 through Table 4 provide a summary of the potential environmental impacts of the project. The mitigation measures associated with each impact, which are to be implemented in order to reduce the environmental impacts to the maximum extent feasible, are also summarized therein. In accordance with the State CEQA Guidelines, the tables identify the following types of potential impacts associated with the project:  Class I, Significant and Unavoidable. An impact that cannot be reduced to below the threshold level given reasonably available and feasible mitigation measures. Such an impact requires a ‘Statement of Overriding Considerations’ to be issued if the project is approved per §15093 of the State CEQA Guidelines.  Class II, Significant but Mitigable. An impact that can be reduced to below the threshold level given reasonably available and feasible mitigation measures. Such an impact requires ‘Findings’ to be made under §15091 of the State CEQA Guidelines.  Class III, Less than Significant. An impact that may be adverse, but does not exceed the threshold levels and does not require mitigation measures. However, mitigation measures that could further lessen the environmental effect may be suggested if readily available and easily achievable.  Class IV, Beneficial. An effect that would reduce existing environmental problems or hazards. Significant and Unavoidable Impacts The project would result in five significant and unavoidable (Class I) impacts. Issue areas with Class I impacts include aesthetics (visual character and cumulative visual character), cultural resources (historic resources and cumulative historic resources), and noise (construction noise) as summarized in Table 2. City of San Luis Obispo Palm Nipomo Parking Structure Project 6 Table 2 Class I, Significant and Unavoidable Environmental Impacts Impact Mitigation Measures Residual Impact Aesthetics Impact AES-2. The project would permanently alter the existing visual character of the site because it would introduce new structures that are substantially different in terms of size, scale, and massing. This impact is Class I, significant and unavoidable. As discussed in the impact analysis and described in the project description, the project includes various features that are intended to mitigate visual impacts. No additional mitigation measures are feasible. The project design features would reduce visual impacts to the extent feasible; however, due to the size, scale, and massing of the project, impacts related to a change in visual character would remain significant and unavoidable. Cumulative Aesthetics Impact. The project would result in a significant and unavoidable impact associated with change in visual character due to the increase in size, scale, and massing of the project. This combined with other cumulative development in the area would increase the intensity of development in the area and permanently alter the visual character. Therefore, the project would result in a Class I, significant and unavoidable, cumulative impact. As discussed in the impact analysis and described in the project description, the project includes various features that are intended to mitigate visual impacts. No additional mitigation measures are feasible to address cumulative impacts. The project features would reduce the project’s visual impacts to the extent feasible; however, impacts to change in visual character would be cumulatively considerable. Cultural and Tribal Cultural Resources Impact CR-1. Construction of the project would result in demolition of two structures on the project site that are historic resources, and adversely affect the Downtown Historic District. This would cause a substantial adverse change in the significance of historic resources as defined in CEQA Guidelines §15064.5. This impact is Class I, significant and unavoidable. CR-1 Historical Building Documentation Packages. Impacts to historical resources shall be minimized through the preparation of archival historic building documentation packages for both 610 and 614 Monterey Street. Prior to issuance of demolition permits, the City of San Luis Obispo shall ensure that documentation of both properties is completed in the form of a Historic American Building Survey (HABS)-Like documentation that shall comply with the Secretary of the Interior’s Standards for Architectural and Engineering Documentation (NPS 1990). The documentation shall generally follow the HABS Level III requirements and include high-quality digital photographic recordation of the buildings and their overall setting, detailed historic narrative report, and compilation of historic research. The documentation shall be completed by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). Individual archival documentation packages shall be completed both properties and offered as donated material to the San Luis Obispo Library and the History Center of San Luis Obispo County, where it would be available to local researchers. Completion of this mitigation measure shall be monitored and enforced by the lead agency. Implementation of Mitigation Measure CR-1 would reduce impacts to historical resources to the greatest extent possible; however, this measure would not eliminate the permanent impacts to the identified historic resources, and no other feasible mitigation measures are available. Therefore, the project would result in a significant and unavoidable impact to historic resources. Executive Summary Final Environmental Impact Report 7 Impact Mitigation Measures Residual Impact Cumulative Cultural Resources Impact. The project would result in a significant and unavoidable impact associated with the removal of historic structures that contribute to the Downtown Historic District. As such, the project would contribute to the cumulative loss of historic resources in the City. This would be a Class I, significant and unavoidable, cumulative impact to historical resources. No additional mitigation is available to address cumulative cultural resources impacts. Implementation of Mitigation Measure CR-1 would reduce this impact to the greatest extent possible; however, cumulative cultural resources impacts would remain significant and unavoidable. Noise Impact N-1. Short-term construction activity would temporarily generate noise that would exceed City noise thresholds. Mitigation is available to reduce temporary construction noise, but would not be sufficient to reduce impacts to less than the applicable thresholds. This impact is Class I, significant and unavoidable. N-1(a) Construction Vehicle Travel Route. Construction vehicles and haul trucks shall utilize roadways which avoid residential neighborhoods and sensitive receptors where possible. The applicant shall submit a proposed construction vehicle and hauling route for City review and approval prior to grading/building permit issuance. The approved construction vehicle and hauling route shall be used for all construction vehicles and hauling trips during the duration of construction. N-1(b) Construction Activity Timing. Except for emergency repair of public service utilities or where an exception is issued by the Community Development Department, no operation of tools or equipment used in construction, drilling, repair, alteration, or demolition work shall occur daily between the hours of 7:00 PM and 7:00 AM, or anytime on Sundays, holidays, or after sunset, where that operation creates a noise disturbance that exceeds 75 dBA for single family residential, 80 dBA for multi-family residential, and 85 dBA for mixed residential/commercial land uses across a residential or commercial property line for a maximum of 10 days. For construction activities lasting more than 10 days, noise from construction equipment shall not exceed 60 dBA for single family residential, 65 dBA for multi-family residential, and 70 dBA for mixed residential/commercial land uses across a residential or commercial property line. Mitigation Measures N-1(a) through N-1(d) would require implementation of noise reduction devices and techniques during construction, and would reduce noise associated with on- and offsite construction activity to the maximum extent feasible. However, temporary noise impacts associated with onsite and offsite construction activity would be significant and unavoidable. N-1(c) Construction Equipment Best Management Practices (BMPs). For all construction activity at the project site, noise attenuation techniques shall be employed to reduce noise levels to extent feasible in accordance with the City of San Luis Obispo Municipal Code, Title 9, Chapter 9.12 (Noise Control). Such techniques shall include:  Sound blankets on noise-generating equipment  Stationary construction equipment that generates noise levels above 60 dBA at the project boundaries shall be shielded with barriers that meet a sound transmission class (a rating of how well noise barriers attenuate sound) of 25 City of San Luis Obispo Palm Nipomo Parking Structure Project 8 Impact Mitigation Measures Residual Impact  All diesel equipment shall be operated with closed engine doors and shall be equipped with factory- recommended mufflers  For stationary equipment, the applicant shall designate equipment areas with appropriate acoustic shielding on building and grading plans. Equipment and shielding shall be installed prior to construction and remain in the designated location throughout construction activities  Electrical power shall be used to power air compressors and similar power tools  The movement of construction-related vehicles, with the exception of passenger vehicles, along roadways adjacent to sensitive receptors shall be limited to the hours between 7:00 AM and 7:00 PM, Monday through Saturday and no movement of heavy equipment shall occur on Sundays or official holidays (e.g., Thanksgiving, Labor Day)  Temporary sound barriers shall be constructed between construction sites and affected uses N-1(d) Neighborhood Property Owner Notification and Construction Noise Complaints. The contractor shall inform residents and business operators at properties within 300 feet of the project site of proposed construction timelines and noise complaint procedures to minimize potential annoyance related to construction noise. Proof of mailing the notices shall be provided to the Community Development Department before the City issues a zoning clearance. Signs shall be in place before beginning of and throughout grading and construction activities. Noise- related complaints shall be directed to the City’s Community Development Department. Executive Summary Final Environmental Impact Report 9 Table 3 Class II, Significant but Mitigable Environmental Impacts Impact Mitigation Measures Residual Impact Aesthetics Impact AES-3. Implementation of the project would result in an increase in nighttime lighting and daytime glare at the project site; however, with mitigation, this increase would not adversely affect day or nighttime views in the area. This impact would be Class II, significant but mitigable. AES-3(a) Lighting Plan. Prior to issuance of building permits, the applicant shall prepare and submit a comprehensive lighting plan for Architectural Review Committee review and approval. The lighting plan shall be consistent with the Municipal Code Night Sky Ordinance, and prepared using guidance and best practices endorsed by the International Dark Sky Association. The lighting plan shall address all aspects of the lighting, including but not limited to all buildings, infrastructure, driveways, paths, plazas, safety, and signage. The lighting plan must include identification of all types, sizes, and intensities of wall mounted building lights and landscape accent lighting, and a photometric map must be provided. The lighting plan shall include the following: a. The point source of all exterior lighting shall be shielded from offsite views b. Light trespass from exterior lights shall be minimized by directing light downward and utilizing cut-off fixtures or shields c. Lumination from exterior lights shall be the lowest level allowed by public safety standards d. Exterior lighting shall be designed to not focus illumination onto exterior walls e. Any signage visible from offsite shall not be internally laminated AES-3(b) Glare Reduction. To minimize impacts on residential development in proximity to the project site, roof and building materials shall be non-reflective, and shall be muted in hues consistent with standards in the Community Design Guidelines, Section 6.1-C. Implementation of Mitigation Measures AES-3(a) and AES-3(b) would reduce impacts associated with light and glare to a less than significant level. Cultural and Tribal Cultural Resources Impact CR-2. Construction of the project would result in ground disturbance that could cause a substantial adverse change in the significance of an archaeological resource as defined in CEQA Guidelines 15064. This impact would be Class II, significant but mitigable. CR-2(a) Retain a Qualified Principal Investigator. A qualified principal investigator, defined as an archaeologist who meets the Secretary of the Interior’s Standards for professional archaeology (hereafter qualified archaeologist), shall be retained to carry out all mitigation measures related to archaeological resources. CR-2(b) City of San Luis Obispo Consolidated Approach for Archaeological Investigations. Mitigation of archaeological resources within the project area shall follow the Consolidated Approach as outlined in the City of San Luis Obispo Archaeological Resource Preservation Program Guidelines. The Consolidated Approach shall include (1) the preparation of a Research Design and Mitigation Plan prepared by the qualified archaeologist and submitted for written approval to the City’s Community Development Director (Director), which shall include but not be limited to the research design, laboratory and field methods, public interpretation, and location of curation; (2) monitoring of demolition and Implementation of Mitigation Measures CR-2(a) through CR-2(d) would reduce impacts to archaeological resources to a less than significant level. City of San Luis Obispo Palm Nipomo Parking Structure Project 10 Impact Mitigation Measures Residual Impact clearing of pavement within the project area; (3) fieldwork after the removal of pavement consisting of a Phase I inventory, Phase 2 Testing and Evaluation, and Phase 3 Data Recovery aimed at locating archaeological remains, evaluating their significance and integrity, and mitigating impacts through data recovery excavation; (4) the completion of special studies, such as faunal analysis, if appropriate, and the curation of recovered artifacts; and (5) the completion of a technical report documenting the results of the consolidated approach prepared in accordance with current professional standards and submitted to the Director. CR-2(c) Archaeological Monitoring. An archaeological monitor shall be present for all project-related ground- disturbing construction activities. The monitor(s) shall be onsite on a full-time basis during earthmoving activities, including grading, trenching, vegetation removal, or other excavation activities. Under consultation between the qualified archaeologist and the City, monitoring may be reduced or eliminated based on observed conditions. CR-2(d) Unanticipated Discovery of Archaeological Resources. In the event that cultural resources are encountered during the implementation of mitigation measures CR-2b or CR-2c, all work shall be halted in the vicinity of the discovery until a qualified archaeologist can assess the significance of the resource. If the resources are found to be significant, they must be avoided or mitigated pursuant to the qualified archaeologist’s direction and the testing plan outlined under MM CR-2b. Mitigation may involve preservation in place or documentation and excavation of the resource. A report by the archaeologist evaluating the find and identifying mitigation actions taken shall be submitted to the City. Impact CR-3. Construction of the project would result in ground disturbance that could indirectly or directly destroy a unique paleontological resource. This impact would be Class II, significant but mitigable. CR-3(a) Qualified Project Paleontologist. A qualified project paleontologist, defined as a paleontologist who meets the standards of the SVP (2010), shall be retained to carry out all mitigation measures related to paleontological resources. CR-3(b) Worker Environmental Awareness Program (WEAP). Prior to the start of construction, the project paleontologist or his or her designee shall conduct training for construction personnel regarding the appearance of fossils and the procedures for notifying paleontological staff should fossils be discovered by construction staff. The WEAP shall be fulfilled at the time of a preconstruction meeting at which a qualified paleontologist shall attend. CR-3(c) Paleontological Monitoring. Ground-disturbing construction activities (including grading, trenching, foundation work, and other excavations) in previously undisturbed sediments that exceed 10 feet in depth shall be monitored on a full-time basis during initial ground disturbance. Monitoring shall be conducted by a qualified paleontological monitor, who is defined as an individual who has experience with collection and salvage of paleontological resources and meets the minimum Implementation of Mitigation Measures CR-3(a) through CR-3(d) would reduce impacts to paleontological resources to a less than significant level. Executive Summary Final Environmental Impact Report 11 Impact Mitigation Measures Residual Impact standards of the SVP (2010). The duration and timing of the monitoring will be determined by the project paleontologist and the location and extent of proposed ground disturbance. If the project paleontologist determines that full-time monitoring is no longer warranted, based on the specific geologic conditions at the surface or at depth, the project paleontologist may recommend that monitoring be reduced to periodic spot- checking or cease entirely. Monitoring is not necessary in artificial fill or for activities that do not reach 10 feet in depth. CR-3(d) Fossil Discoveries. In the event of a fossil discovery by the paleontological monitor or construction personnel, all work in the immediate vicinity of the find shall cease. The project paleontologist shall evaluate the find before restarting construction activity in the area. If it is determined that the fossil(s) is (are) scientifically significant, the project paleontologist shall complete the following conditions to mitigate impacts to significant fossil resources: 1) Salvage of Fossils. The project paleontologist (or paleontological monitor) shall recover significant fossils following standard field procedures for collecting paleontological resources, as described by the SVP (2010). Typically, fossils can be safely salvaged quickly by a single paleontologist and not disrupt construction activity. In some cases, larger fossils (such as complete skeletons or large mammal fossils) require more extensive excavation and longer salvage periods. In this case the paleontologist shall have the authority to temporarily direct, divert or halt construction activity to ensure that the fossil(s) can be removed in a safe and timely manner. 2) Preparation and Curation of Recovered Fossils. Once salvaged, significant fossils shall be identified to the lowest possible taxonomic level, prepared to a curation- ready condition, and curated in a scientific institution with a permanent paleontological collection (such as the University of California Museum of Paleontology), along with all pertinent field notes, photos, data, and maps. Fossils of undetermined significance at the time of collection may also warrant curation at the discretion of the project paleontologist. Impact CR-5. Ground-disturbing activities associated with construction of the project have the potential to disturb unidentified human remains. This impact would be Class II, significant but mitigable. Compliance with existing regulations and Mitigation Measure CR-2(d) would ensure that impacts to human remains and burial grounds would remain less than significant. Implementation of Mitigation Measure CR- 2(d) would reduce this impact to a less than significant level. Cumulative Noise Impact. Construction of the proposed project could overlap with the construction of other projects in the vicinity (Monterey Place and the Vesper Hotel at the N-4 Coordination of Construction Timing. Prior to the issuance of grading permits, the City of San Luis Obispo shall review and coordinate the construction schedules of any other projects within 300 feet of the project to ensure that construction schedules do not overlap. Implementation of Mitigation Measure N-4 would avoid additional cumulative construction noise impacts and reduce City of San Luis Obispo Palm Nipomo Parking Structure Project 12 Impact Mitigation Measures Residual Impact Creamery) which would result in a significant cumulative impact. The project’s incremental contribution would be cumulatively considerable. cumulative impacts to a less than significant level. Transportation Impact T-3. Implementation of the project would result in pedestrian access impacts due to the difficulty of crossing Nipomo Street at an uncontrolled location. This impact would be Class II, significant but mitigable. T-3 Pedestrian Access. Subject to approval of the Public Works Director, the City shall incorporate improvements to the intersections of Dana Street/Nipomo Street and Monterey Street/Nipomo Street to enhance pedestrian safety and accessibility. The improvements shall be consistent with the City’s Circulation Element and Downtown Physical Concept Plan (2017) and shall balance the needs of each mode of use. At a minimum the project should consider:  High visibility crosswalk, or other intersection enhancements, with directional curb ramps across Nipomo Street from the northwest corner of Dana Street/Nipomo Street to the southwest corner of the parking structure.  High visibility crosswalk, or other intersection enhancements, with directional curb ramps from the southeast corner of Monterey Street/Nipomo Street across Nipomo Street.  Standard crosswalks, or other intersection enhancements, with directional curb ramps across Monterey Street and Dana Street where they intersect with Nipomo Street.  Reduce the curb radii on the southwest corner of Dana Street/Nipomo Street and the northeast corner of Monterey Street/Nipomo Street. Implementation of Mitigation Measure T-3 would reduce this impact to a less than significant level. Cumulative Traffic Impact. Under Cumulative plus Project conditions, one study intersection (the project driveway at Nipomo Street) would operate at an unacceptable level of service for pedestrians during the evening peak hour. This impact would be Class II, significant but mitigable. Mitigation Measure T-3 would be required. Implementation of Mitigation Measure T-3 would reduce impacts to a less than significant level. Air Quality (from Initial Study) Construction of the project would generate temporary increases in localized air pollutant emissions (fugitive dust, ozone precursors, and diesel particulate matter emissions) within 1,000 of sensitive receptors. In addition the South Coast Air Basin is in non-attainment for SCCAB is in non-attainment for PM10. This impact would be Class II, significant but mitigable. AQ-1 Fugitive Dust Control Measures. Construction projects shall implement the following dust control measures so as to reduce PM10 emissions in accordance with San Luis Obispo Air Pollution Control District (SLOAPCD) requirements.  Reduce the amount of the disturbed area where possible  Water trucks or sprinkler systems shall be used during construction in sufficient quantities to prevent airborne dust from leaving the site. Increased watering frequency shall be required whenever wind speeds exceed 15 mph. Reclaimed (non-potable) water shall Implementation of Mitigation Measures AQ-1 and AQ-2(a) through AQ-2(c) would reduce impacts to a less than significant level. Executive Summary Final Environmental Impact Report 13 Impact Mitigation Measures Residual Impact be used whenever possible  All dirt stock pile areas shall be sprayed daily as needed  Permanent dust control measures identified in the approved project revegetation and landscape plans shall be implemented as soon as possible following completion of any soil disturbing activities  Exposed ground areas that are planned to be reworked at dates greater than one month after initial grading shall be sown with a fast germinating, non- invasive grass seed and watered until vegetation is established  All disturbed soil areas not subject to revegetation shall be stabilized using approved chemical soil binders, jute netting, or other methods approved in advance by the SLOAPCD  All roadways, driveways, sidewalks, etc. to be paved shall be completed as soon as possible after grading unless seeding or soil binders are used  Vehicle speed for all construction vehicles shall not exceed 15 miles per hour (mph) on any unpaved surface at the construction site  All trucks hauling dirt, sand, soil, or other loose materials are to be covered or shall maintain at least two feet of freeboard (minimum vertical distance between top of load and top of trailer) in accordance with California Vehicle Code Section 23114  Install wheel washers where vehicles enter and exit unpaved roads onto streets, or wash off trucks and equipment leaving the site  Sweep streets at the end of each day if visible soil material is carried onto adjacent paved roads. Water sweepers with reclaimed water shall be used where feasible  All of these fugitive dust mitigation measures shall be shown on grading and building plans  The contractor or builder shall designate a person or persons to monitor the fugitive dust emissions and enhance the implementation of the measures as necessary to minimize dust complaints, reduce visible emissions below 20 percent opacity, and to prevent transport of dust offsite. Their duties shall include holidays and weekend periods when work may not be in progress. The name and telephone number of such persons shall be provided to the SLOAPCD Compliance Division prior to the start of any grading, earthwork, or demolition. AQ-2(a) Standard Control Measures for Construction Equipment. The following standard air quality mitigation measures shall be implemented during construction activities at the project site:  Maintain all construction equipment in proper tune according to manufacturer’s specifications  Fuel all off-road and portable diesel powered equipment with ARB certified motor vehicle diesel fuel City of San Luis Obispo Palm Nipomo Parking Structure Project 14 Impact Mitigation Measures Residual Impact (non-taxed version suitable for sue off-road)  Use diesel construction equipment meeting ARB’s Tier 2 certified engines or cleaner off-road heavy-duty diesel engines, and comply with the State Off-Road Regulation  Use on-road heavy-duty trucks that meet the ARB’s 2007 or cleaner certification standard for on-road heavy-duty diesel engines, and comply with the State On-Road Regulation  Construction or trucking companies with fleets that do not have engines in their fleet that meet the engine standards identified in the above two measures (e.g., captive or NOX exempt area fleets) may be eligible by proving alternative compliance  All on- and off-road diesel equipment shall not idle for more than 5 minutes. Signs shall be posted in the designated queuing areas and or job sites to remind drivers and operators of the 5 minute idling limit  Diesel idling within 1,000 feet of sensitive receptors is not permitted  Staging and queuing areas shall not be located within 1,000 feet of sensitive receptors  Electrify equipment when feasible  Substitute gasoline-powered in place of diesel- powered equipment, where feasible  Use alternatively fueled construction equipment onsite where feasible, such as compressed natural gas, liquefied natural gas, propane or biodiesel AQ-2(b) Best Available Control Technology (BACT) for Construction Equipment. The following BACT for diesel- fueled construction equipment shall be implemented during construction activities at the project site, where feasible:  Further reduce emissions by expanding use of Tier 3 and Tier 4 off-road and 2010 on-road compliant engines where feasible  Repower equipment with the cleanest engines available  Install California Verified Diesel Emission Control Strategies, such as level 2 diesel particulate filters (these strategies are listed at: www.arb.ca.gov/diesel/verdev/vt/cvt.htm) AQ-2(c) Architectural Coating. To reduce ROG and NOX levels during the architectural coating phase, low or no VOC-emission paint shall be used with levels of 50 g/L or less. Biological Resources (from Initial Study) Construction of the project would involve general construction activity and tree removal that may affect protected nesting birds. Impacts to migratory bird species would be potentially significant unless mitigation is BIO-1 Nesting Bird Protection. To avoid disturbance of nesting and special-status birds, activities related to the project, including, but not limited to, vegetation removal, ground disturbance, and construction and demolition shall occur outside of the bird breeding season (typically February through August in the project region). If construction must begin within the breeding season, then Implementation of Mitigation Measure BIO-1 would reduce impacts to a less than significant level. Executive Summary Final Environmental Impact Report 15 Impact Mitigation Measures Residual Impact incorporated. a pre-construction nesting bird survey shall be conducted no more than 3 days prior to initiation of ground disturbance and vegetation removal activities. The nesting bird pre-construction survey shall be conducted within the Project Boundary, including a 300-foot buffer (500-foot for raptors), on foot, and within inaccessible areas (i.e., private lands) afar using binoculars to the extent practical. The survey shall be conducted by a biologist familiar with the identification of avian species known to occur in the area. If nests are found, an avoidance buffer (which is dependent upon the species, the proposed work activity, and existing disturbances associated with land uses outside of the site) shall be determined and demarcated by the biologist with bright orange construction fencing, flagging, construction lathe, or other means to mark the boundary. All construction personnel shall be notified as to the existence of the buffer zone and to avoid entering the buffer zone during the nesting season. No ground- disturbing activities shall occur within this buffer until the avian biologist has confirmed that breeding/nesting is completed and the young have fledged the nest. Encroachment into the buffer shall occur only at the discretion of the qualified biologist. Geology and Soils (from Initial Study) Implementation of the project would occur on soils that have moderate to high expansion potential. This impact would be potentially significant unless mitigation is incorporated. GEO-1 Minimization of Expansive Soil Hazards. Once the final maximum loads of the project have been determined, a design-level geotechnical report shall be prepared that identifies the most appropriate geotechnical improvements to onsite soils, the foundation, and parking structure to minimize expansive soil hazards. Recommendations could include, but are not limited to the following:  Use imported non-expansive materials combined with pre-moistening of the soils to provide protection for slabs and flatwork  Provide a layer of non-expansive material 18 to 24 inches thick  Use post-tensioned slabs-on-grade  Implement shoring methods, such as shotcrete-faced soil nail walls, tangent drilled caissons, whaler-braced retaining walls, and steel I-beam and lagging walls  Use over-excavation and recompaction  Utilize a deep foundation system, such as caissons or rammed aggregate piers A certified soils engineer shall be retained for monitoring during construction of the project. The certified soils engineer shall also provide any necessary soil testing during construction, to ensure compliance with the design-level geotechnical report, and to provide site- specific guidance as subsurface materials are encountered. Implementation of Mitigation Measure GEO-1 would reduce impacts to a less than significant level. City of San Luis Obispo Palm Nipomo Parking Structure Project 16 Impact Mitigation Measures Residual Impact Hazardous Materials (from Initial Study) Construction of the project would require excavation and removal of existing fill, which has the potential to be contaminated. Therefore, construction activities could expose workers to contaminated soil onsite. This impact would be potentially significant unless mitigation is incorporated. HAZ-1 Hazardous Materials Soil Sampling and Remediation. Prior to issuance of grading permits, additional soil samples testing for total petroleum hydrocarbons shall be performed. A work plan shall be completed to address the sampling protocols to be followed, as well as the number of samples to be taken and the chemical analysis required. Upon City of San Luis Obispo approval, the work plan shall be implemented and the results of the soil sampling shall be forwarded to the City of San Luis Obispo. The City shall review the data to determine if any additional investigation or remedial activities are deemed necessary. No work shall resume in that area until the lead local regulatory agency has provided written authorization that the area does not warrant any additional action. If concentrations of contaminants warrant remediation, contaminated materials shall be remediated either prior to or concurrent with construction. Remediation shall generally include a management plan which establishes design and implementation of remediation. Cleanup may include excavation, disposal, bio-remediation, or any other treatment of conditions subject to regulatory action. All necessary reports, regulations and permits shall be followed to achieve cleanup of the site. The contaminated materials shall be remediated under the supervision of an environmental consultant licensed to oversee such remediation and under the direction of the lead oversight agency. The remediation program shall also be approved by the San Luis Obispo Fire Department. All proper waste handling and disposal procedures shall be followed. Upon completion of the remediation, the environmental consultant shall prepare a report summarizing the project, the remediation approach implemented, and the analytical results after completion of the remediation, including all waste disposal or treatment manifests. Implementation of Mitigation Measure HAZ-1 would reduce impacts to a less than significant level Transportation (from Initial Study) Construction of the project would result in short term construction traffic, construction parking, and modifications to existing pedestrian, bicycle, and transit circulation during the construction period. This impact would be potentially significant unless mitigation is incorporated. T-1 Construction Management Plan. Prior to the issuance of each building permit, the construction contractor shall meet with the Public Works department to determine traffic management strategies to reduce, to the maximum extent feasible, traffic congestion and the effects of parking demand by construction workers during construction of this project. The construction contractor will develop a construction management plan for review and approval by the Public Works department. The plan shall include at least the following items and requirements:  A set of comprehensive traffic control measures, including scheduling of major truck trips and deliveries to avoid peak traffic and pedestrian hours, detour signs if required, lane closure procedures, sidewalk closure procedures, signs, cones for drivers, and designated construction access routes.  Notification procedures for adjacent property owners and public safety personnel regarding when major Implementation of Mitigation Measure T-1 would reduce impacts to a less than significant level. Executive Summary Final Environmental Impact Report 17 Impact Mitigation Measures Residual Impact deliveries, detours, and lane closures will occur.  Location of construction staging areas for materials, equipment, and vehicles (must be located on the project site).  Identification of haul routes for movement of construction vehicles that would minimize impacts on vehicular and pedestrian traffic, circulation and safety; and provision for monitoring surface streets used for haul routes so that any damage and debris attributable to the haul trucks can be identified and corrected by the project applicant.  Temporary construction fences to contain debris and material and to secure the site.  Provisions for removal of trash generated by project construction activity.  A process for responding to and tracking complaints pertaining to construction activity.  Provisions for monitoring surface streets used for truck routes so that any damage and debris attributable to the trucks can be identified and corrected.  It is anticipated that this Construction Traffic Management Plan would be developed in the context of a larger Construction Management Plan, which would address other issues such as hours of construction onsite, limitations on noise and dust emissions, and other applicable items. City of San Luis Obispo Palm Nipomo Parking Structure Project 18 Table 4 Class III, Less than Significant Environmental Impacts Impact Mitigation Measures Residual Impact Aesthetics Impact AES-1. The project would not have a substantial adverse impact on a scenic vista because it is not located in a city-designated scenic vista. This impact would be Class III, less than significant. No mitigation measures are required. Less than Significant Cultural and Tribal Cultural Resources Impact CR-4. No Tribal Cultural Resources were identified within the project site, but area is generally considered sensitive for cultural resources. This impact would be Class III, less than significant. No mitigation measures are required. Less than Significant Noise Impact N-2. Short term construction activities would generate intermittent levels of groundborne vibration that would be perceptible, but would not exceed applicable thresholds. This impact would be Class III, less than significant. No mitigation measures are required. Less than Significant Impact N-3. The project would generate operational noise from project-generated traffic and new commercial and parking uses. Noise from the project would not exceed acceptable noise levels at existing off -site sensitive receptors. This impact would be Class III, less than significant. No mitigation measures are required. Less than Significant Cumulative Noise Impact. Under Cumulative Plus Project Conditions, noise levels would not exceed thresholds. Impacts would not be significant or cumulatively considerable. No mitigation measures are required. Less than Significant Transportation Impact T-1. Under Existing Plus Project conditions, all intersections and segments would operate at acceptable levels of service for vehicles, pedestrians, bicycles, and transit. These impacts would be Class III, less than significant. No mitigation measures are required. Less than Significant Impact T-2. The project would not add roadway capacity that would induce travel and would not generate new travel demand as a land use. In addition, the City actively manages parking demand and encourages non-auto modes of travel. Therefore, the project would have a negligible impact on vehicle miles traveled (VMT). This impact would be Class III, less than significant. No mitigation measures are required. Less than Significant Cumulative Traffic Impact. Under Cumulative plus Project conditions, all study intersections and segments would operate at acceptable levels of service for vehicles, and all segments would operate at acceptable levels of service for bicycles and transit. These impacts would be Class III, less than significant. No mitigation measures are required. Less than Significant Introduction Final Environmental Impact Report 19 1 Introduction This document is an Environmental Impact Report (EIR) that examines the potential effects of constructing the Palm-Nipomo Project on a 1.38-acre site in the City of San Luis Obispo, California. The project is described in detail in Section 2.0, Project Description. This chapter describes: (1) the background of the EIR; (2) the purpose of and legal authority for the EIR; (3) the scope and content of the EIR; (4) lead, responsible and trustee agencies; and (5) the environmental review process required under the California Environmental Quality Act (CEQA). 1.1 Environmental Impact Report Background The City of San Luis Obispo prepared an Initial Study and circulated a Notice of Preparation (NOP) of this EIR for a 30-day agency and public review period starting on May 1, 2017. The Initial Study serves as the scoping document for this EIR. The Initial Study determined that the proposed project required the preparation of an EIR to further evaluate potential impacts related to the following environmental issue areas: aesthetics, cultural resources, noise, and transportation. The City received two letters in response to the NOP. The Initial Study, NOP, and NOP comment letters are presented in Appendix A to this EIR. An EIR scoping meeting was also held on May 10, 2017, in the City Council Chamber, and comments on the scope of the EIR were received from private citizens and the Planning Commissioners. Key issues of concern that were noted in the NOP responses and voiced at the EIR scoping meeting included the following:  Impacts on views of Cerro San Luis Obispo  Size and scale of the project and its aesthetic compatibility with the historical character or surrounding development  Impacts to historical resources, including the adobe on the project site  Impacts to tribal cultural resources  Increase in operational noise and its impact on sensitive receptors  Vehicle trips generated by project  Pedestrian-vehicle conflicts; pedestrian safety crossing Nipomo Street  Induced travel  Sources of greenhouse gas emissions  Alternatives to the project 1.2 Purpose and Legal Authority This EIR has been prepared in accordance with CEQA and the CEQA Guidelines. In accordance with Section 15121(a) of the CEQA Guidelines, the purpose of this EIR is to serve as an informational document that: City of San Luis Obispo Palm Nipomo Parking Structure Project 20 “will inform public agency decision-makers and the public generally of the significant environmental effects of a project, identify possible ways to minimize the significant effects, and describe reasonable alternatives to the project” This report serves as an informational document for the public and the City of San Luis Obispo decision-makers. The proposed project requires discretionary approval from the City and, therefore, is subject to CEQA’s environmental review requirements. The process will culminate with Planning Commission and City Council hearings to consider certification of a Final EIR and make a decision whether to approve the proposed project, possibly with conditions of approval, or with modifications to the project. 1.3 Scope and Content This EIR addresses the issues determined to be potentially significant in the Initial Study, and based on responses to the NOP and scoping discussions among the public, consulting staff, and the City. The environmental issues addressed in impact sections in this EIR include:  Aesthetics  Cultural Resources  Noise  Transportation All other impacts were addressed in the Initial Study and the associated technical studies prepared as part of the project application and are summarized in Section 5.0, Issues Addressed in the Initial Study. The impact analysis contained in Section 4.0 includes a description of the physical and regulatory setting, followed by an analysis of the proposed project’s impacts in that area. Each potential impact is numbered separately, followed by an explanation of how the level of impact was determined. When appropriate, the EIR identifies feasible mitigation measures. Following the mitigation measures are a discussion of any residual impacts or secondary impacts. The alternatives section of the EIR (Section 7.0) was prepared in accordance with Section 15126.6 of the CEQA Guidelines that requires an EIR to examine a reasonable range of alternatives capable of avoiding or minimizing a project’s significant effects while achieving most of the basic project objectives. The alternatives discussion evaluates the CEQA-required “no project” alternative and three alternative development scenarios for the site. It also identifies the environmentally superior alternative among the alternatives assessed. In preparing the EIR, use was made of pertinent City policies and guidelines, existing EIRs and background documents prepared by the City, and documents that guide land use in the city. A full reference list is contained in Section 8.0, References, of this EIR. The level of detail contained throughout this EIR is consistent with the requirements of CEQA and applicable court decisions. The State CEQA Guidelines provide the standard of adequacy on which this document is based. The Guidelines state: “An EIR should be prepared with a sufficient degree of analysis to provide decision-makers with information which enables them to make a decision which intelligently takes account of environmental consequences. An evaluation of the environmental effects of the proposed project need not be exhaustive, but the sufficiency of an EIR is to be reviewed in light of what is reasonably feasible. Disagreement among experts does not make an EIR inadequate, but the EIR Introduction Final Environmental Impact Report 21 should summarize the main points of disagreement among the experts. The courts have looked not for perfection, but for adequacy, completeness, and a good faith effort at full disclosure (Section 15151).” 1.4 Lead, Responsible, and Trustee Agencies The State CEQA Guidelines define “lead,” “responsible” and “trustee” agencies. The City of San Luis Obispo is the lead agency for the project because it has the principal responsibility for approving the project. A “responsible agency” refers to a public agency other than the lead agency that has discretionary approval over the project. The Regional Water Quality Control Board is a Responsible Agency because the proposed project would require a National Pollutant Discharge Elimination System Permit. A “trustee agency” refers to a state agency having jurisdiction by law over natural resources affected by a project. There are no trustee agencies with jurisdiction on the site. 1.5 Environmental Review Process The environmental review process required under CEQA is summarized below and shown in Figure 1. The steps appear in sequential order. 1. Notice of Preparation (NOP) Distributed. Immediately after deciding that an EIR is required, the lead agency must file a NOP soliciting input on the EIR scope to "responsible," "trustee," and involved federal agencies; to the State Clearinghouse, if one or more state agencies is a responsible or trustee agency; and to parties previously requesting notice in writing. The NOP must be posted in the County Clerk's office for 30 days. A scoping meeting to solicit public input on the issues to be assessed in the EIR is not required, but may be conducted by the lead agency. 2. Draft EIR Prepared. The Draft EIR must contain: a) table of contents or index; b) summary; c) project description; d) environmental setting; e) significant impacts (direct, indirect, cumulative, growth-inducing and unavoidable impacts); f) alternatives; g) mitigation measures; and h) irreversible changes. 3. Public Notice and Review. A lead agency must prepare a Public Notice of Availability of an EIR. The Notice must be placed in the County Clerk's office for 30 days (Public Resources Code Section 21092) and sent to anyone requesting it. Additionally, public notice of Draft EIR availability must be given through at least one of the following procedures: a) publication in a newspaper of general circulation; b) posting on and off the project site; and c) direct mailing to owners and occupants of contiguous properties. The lead agency must consult with and request comments on the Draft EIR from responsible and trustee agencies, and adjacent cities and counties. The minimum public review period for a Draft EIR is 30 days. When a Draft EIR is sent to the State Clearinghouse for review, the public review period must be 45 days, unless a shorter period is approved by the Clearinghouse (Public Resources Code 21091). Distribution of the Draft EIR may be required through the State Clearinghouse. 4. Notice of Completion. A lead agency must file a Notice of Completion with the State Clearinghouse as soon as it completes a Draft EIR. City of San Luis Obispo Palm Nipomo Parking Structure Project 22 5. Final EIR. A Final EIR must include a) the Draft EIR; b) copies of comments received during public review; c) list of persons and entities commenting; and d) responses to comments. 6. Certification of Final EIR. The lead agency shall certify: a) the Final EIR has been completed in compliance with CEQA; b) the Final EIR was presented to the decision-making body of the lead agency; and c) the decision-making body reviewed and considered the information in the Final EIR prior to approving a project. 7. Lead Agency Project Decision. A lead agency may: a) disapprove a project because of its significant environmental effects; b) require changes to a project to reduce or avoid significant environmental effects; or c) approve a project despite its significant environmental effects, if the proper findings and statement of overriding considerations are adopted. 8. Findings/Statement of Overriding Considerations. For each significant impact of the project identified in the EIR, the lead or responsible agency must find, based on substantial evidence, that either: a) the project has been changed to avoid or substantially reduce the magnitude of the impact; b) changes to the project are within another agency's jurisdiction and such changes have or should be adopted; or c) specific economic, social, or other considerations make the mitigation measures or project alternatives infeasible. If an agency approves a project with unavoidable significant environmental effects, it must prepare a written Statement of Overriding Considerations that set forth the specific social, economic or other reasons supporting the agency's decision. 9. Mitigation Monitoring/Reporting Program. When an agency makes findings on significant effects identified in the EIR, it must adopt a reporting or monitoring program for mitigation measures that were adopted or made conditions of project approval to mitigate significant effects. 10. Notice of Determination. An agency must file a Notice of Determination after deciding to approve a project for which an EIR is prepared. A local agency must file the Notice with the County Clerk. The Notice must be posted for 30 days and sent to anyone previously requesting notice. Posting of the Notice starts a 30-day statute of limitations on CEQA challenges.

Project Description Final Environmental Impact Report 25 2 Project Description This section describes the proposed project, including the project applicant, the project site and surrounding land uses, major project characteristics, project objectives, and discretionary actions needed for approval. 2.1 Project Applicant City of San Luis Obispo 919 Palm Street San Luis Obispo, California 93401 (805) 781-7203 2.2 Lead Agency Contact Person City of San Luis Obispo Public Works Department 919 Palm Street San Luis Obispo, California 93401 (805) 781-7203 Contact: Scott Lee, Parking Manager 2.3 Project Location The project site is a 1.38-acre property located in San Luis Obispo, California. Figure 2 shows the regional location of the project. The site lies in the City’s Downtown Planning Area, adjacent to the Downtown Core. The majority of the site (except for APN 002-412-003) is also located in the City’s Downtown Historic District. Figure 3 shows the location of the project in the context of these planning areas. The project site located at the intersections of Palm and Nipomo streets and Nipomo and Monterey streets (609, 610, 614, 630, 633 Palm Street and 970, 972 Nipomo Street). The property consists of six parcels, including Assessor’s Parcel Numbers (APN) 002-412-001, 002- 412-002, 002-412-003, 002-412-004, 002-412-011, and 002-412-012 (Figure 4). 2.4 Existing Site Characteristics This section describes the current characteristics of the project site. Additional details of the current setting at the site and surrounding locations can be found in Section 3.0, Environmental Setting, as well as in the individual issue area discussions in Section 4.0, Environmental Impact Analysis. City of San Luis Obispo Palm Nipomo Parking Structure Project 26 Figure 2 Regional Location Project Description Final Environmental Impact Report 27 Figure 3 Project Planning Area City of San Luis Obispo Palm Nipomo Parking Structure Project 28 Figure 4 Project Site Location and Surrounding Uses Project Description Final Environmental Impact Report 29 Setting 2.4.1 As shown in Figure 3, the project site is located within the City’s Downtown Planning Area, adjacent to the City’s Downtown Core. The majority of the site (except for APN 002-412-003) is also located in the City’s Downtown Historic District. As such, the existing setting is urban and characterized by a wide variety of uses. The project site has been previously graded and developed and is surrounded by roads and urban structures. A 77-space surface parking lot, one detached garage, and four residential structures with five residences (three single-family residences and one secondary unit adjacent to Palm Street with two apartments) currently occupy the site. Two of the residential units, 610 and 614 Monterey Street, are on the City’s List of Contributing Historic Resources, which identifies structures that contribute to the significance of designated historic districts. The existing parking lot provides public parking in metered stalls owned and operated by the City of San Luis Obispo. Ingress and egress to the lot is available from an at-grade driveway on Palm Street. Elevations onsite range from 190 and 206 feet above mean sea level, and slopes are generally toward the northwest. Mature trees are scattered throughout the site and located on surrounding public sidewalks on Nipomo and Palm Streets. One of the trees on the site is a large oak tree along Monterey Street, which has the potential to be recognized as a “significant tree” by the City Council Tree Committee. The project site also includes several landscaped planting medians and areas. Partial views of Cerro San Luis are available from the central portion of the site. Current Land Use Designation and Zoning 2.4.2 The project site is composed of six parcels. Five of the parcels are currently zoned Office with a Historic Overlay (O-H), as defined by the City’s Zoning Ordinance, and have Office General Plan land use designations (APN 002-412-001, 002-412-002, 002-412-004, 002-412-011, and 002-412-012). These five parcels are located in the City’s Downtown Historic District. One parcel is zoned Medium- High Density Residential (R-3) and has a Medium-High Density Residential General Plan land use designation (APN 002-412-003). Surrounding Land Uses 2.4.3 The area surrounding the site is urbanized. The existing uses surrounding the site are shown in Figure 4, and include the following:  West. Existing development across Nipomo Street includes the Reis Family Mortuary & Crematory with surface parking lot and a residential complex comprised of multiple buildings. The area comprising the mortuary has a land use designation of Office and is zoned Office with a Historic Overlay (O-H), while the residential complex has a land use designation of Medium-High Density Residential and is zoned Medium-High Density Residential (R-3).  South. South of the site is the San Luis Obispo Children’s Museum and two residences designated as City contributing historic resources along Monterey Street. The parcel that houses the museum has a land use designation of Public and is zoned Public Facility with a Historic Overlay (PF-H), while the parcels containing the residential units have land use designation of General Retail and are zoned Downtown Commercial with a Special Consideration and Historic Overlay (C-D-S-H). Along Nipomo to the southwest is the Soda Works mixed commercial and residential complex with a land use designation of General Retail and zoned Downtown Commercial with a Planned Development and Historic Overlay (C-D-H-PD). City of San Luis Obispo Palm Nipomo Parking Structure Project 30  East. Adjacent to the project site is a two-story multi-family residential complex with surface parking fronting Palm Street and a single-family residence with detached garage, identified as the Hays-Lattimer Adobe historic resource, fronting Monterey Street. The multi-family residential building has a land use designation of Medium-High Density Residential and is zoned Medium-High Density Residential (R-3), while the single family residence has a land use designation of Office and is zoned Office with Historic Overlay (O-H).  North. The Mission College Preparatory School athletic field is located north of the project site across Palm Street. The school is located just west of the athletic field along Palm Street. The area has a land use designation of Medium-High Density Residential. The athletic field is zoned Medium-High Density Residential (R-3), while the school is zoned Medium-High Density Residential with a Historic Overlay (R-3-H). 2.5 Project Characteristics The project would involve the removal of an existing 77-space surface parking lot and five residential structures (including detached garage) and construction of an above-ground five-level parking structure, non-profit theater, and commercial space. Figure 5 shows the proposed site plan. The parking structure would provide up to 445 parking spaces.2 Main vehicular access to the structure would be from Palm Street, with secondary access from Nipomo Street. Vehicle access would not be provided from Monterey Street; however, a direct pedestrian connection would be provided from the structure to Monterey Street. Pedestrian access would also be provided to public sidewalks from each corner of the structure and bicycle access would be provided from Nipomo Street. The parking structure’s maximum height, excluding elevator towers, would be 50 feet (Figure 6). The maximum height of the elevator towers would be 64 feet above grade. The top deck of the parking structure would include a public use space in the northwest corner nearest to Palm and Nipomo Streets. The project would also include 5,000 square feet of commercial space on two levels fronting Nipomo Street. The maximum height of the commercial space would be 41 feet above existing grade. In addition, the project would include a new structure for the San Luis Obispo Little Theatre (now the San Luis Obispo Repertory Theatre or SLO REP) that would front Monterey Street. The theater would be a three-story structure with a gross floor area of roughly 23,841 square feet. The base level would house a rehearsal area, workshop, storage and other amenities. The main level would be comprised of a main theater with 155191 seats, and a smaller theatre with 10099 reconfigurable seats, generating a total of 255290 seats. The third floor would include offices and a conference room. Entry to the theater would be provided at the street level through a public plaza along Monterey Street. The street level plaza would include a public seating area and incorporate public art. The maximum height of the theater would be approximately 43 feet above existing grade. 2 The parking structure is undergoing design refinement with respect to the ultimate number of parking spaces. Based on the current design, the structure would provide 410 parking spaces; however, the analysis conservatively assumes a maximum of up to 445 parking spaces would be provided. Motorcycle parking would be provided in accordance with the ratios required in the City’s Zoning Regulations (§17.16.060). Project Description Final Environmental Impact Report 31 Figure 5 Site Plan City of San Luis Obispo Palm Nipomo Parking Structure Project 32 Figure 6 Nipomo Street Elevation Project Description Final Environmental Impact Report 33 Construction and Demolition Project construction would last approximately 12 months and is anticipated to start in 2019. Project construction would include site preparation, demolition, grading, building construction, architectural coating, and paving. The project would involve the removal of almost all existing public and private improvements and existing trees and vegetation on the site, with the exception of the large oak tree along Monterey Street and the two trees at the corner of Nipomo and Monterey Streets. Demolition activities would involve removal of the existing surface parking lot, four residential structures3, and detached garage. The project would excavate to a depth of approximately 14 feet at the highest point of the site, along the southern and eastern boundaries of the parking structure. In total, earthwork for buildout of the project is estimated to require 6,400 cubic yards of cut, and 700 cubic yards of fill, resulting in a need for approximately 5,700 cubic yards of soil export. The parking structure would be constructed using drilled caissons or rammed aggregate piers to support the structure. The project would not utilize the method of driven piles. Site Access and Circulation Vehicle As mentioned above, vehicle access into and out of the parking structure would be provided via driveways on Palm Street and Nipomo Street, with one lane for ingress and one lane for egress at each driveway. Each driveway entrance would have storage to accommodate two inbound vehicles. The parking structure exits would be designed so that exiting vehicles would have at least 10 feet of a clear sight triangle to the sidewalk on both sides of the exit, unobstructed by building corners, columns, or any other visual impediments. This distance is measured from eight feet behind the stop bar and two feet to the right of the centerline where a driver would be located in a stopped vehicle. Motorcycle parking would be provided in accordance with the ratios required in the City’s Zoning Regulations. Pedestrian Sidewalks on Nipomo Street would be widened to approximately 12 to 18.5 feet. The sidewalks on Palm Street and Monterey Street would be reconstructed, but remain at their current widths. As shown on Figure 5, a pedestrian crosswalk would be installed across Monterey Street, as well as a “bump out” of the sidewalk that extends into the street to increase pedestrian visibility at the crosswalk. Bicycle Bicycle parking would be provided near the parking structure’s Nipomo Street entrance. Access would be shared with the pedestrian entrance, but the width would be 10 feet wide to accommodate both. Short- and long-term bicycle parking would be provided in accordance with the ratios required in the City’s Zoning Regulations. 3 As noted in Section 2.4.1 Setting, there are four residential structures containing five residences (three single-family residences and one secondary unit containing two separate apartments). City of San Luis Obispo Palm Nipomo Parking Structure Project 34 Conceptual Design The following characteristics are proposed design features of the project.  The parking structure would be set back ten feet from the eastern boundary. The theater would be set back from Monterey Street with a public plaza area in front.  The façade of parking structure and commercial space would be designed to resemble a neighborhood building instead of a typical parking structure and with an architectural style similar to the surrounding Spanish Colonial architecture. Architectural design elements would include arches, stucco, tile roof, rusticated base, and multi-paned mullion pattern (Figure 76).  The openings on the parking structure would be articulated with mullions and sized to reflect traditional window openings in a building. Openings on the east side would have solid rails approximately 3.5 feet high.  The Nipomo Street facade reflects and would complement the downtown architecture and steps down the building form to a two-story structure along Nipomo Street (Figure 87).  The theater would have a contemporary design with the primary exterior finish materials being a multi-colored terra cotta, rain-screen panel system eliciting a color scheme complimenting that of the nearby historic Mission San Luis Obispo de Tolosa-namely white, dun, and varying shades of terra cotta clay. Accent and secondary materials would be smooth troweled stucco in a dun tone, and split face and split fluted concrete masonry unit blocks in a terra cotta tone. In addition, there would be two prominent, curved glass curtain walls with brushed aluminum muntins that face Monterey Street. Conceptual Lighting Outdoor lighting would be fully shielded or recessed and downcast, consistent with the City’s Municipal Code. Proposed exterior lighting would consist of dimmable white light-emitting diodes (LED) mounted to the buildings. Lighting inside the parking structure would consist of LED downlights with shielding elements. When viewed from outside of the parking structure, these shielding elements would eliminate any direct views of the light source. Lighting on the rooftop parking level would be provided by pole-mounted LED luminaires compliant with the City of San Luis Obispo Municipal Code, which requires rooftop lights to minimize spill and include full-cutoffs that reduce light pollution at night. To comply with the Title 24 energy codes, the parking structure would be controlled with photocells to conserve energy during daytime operational hours. The parking structure would also utilize occupancy sensors which would turn the lights off when no activity is detected in the structure. The lighting concept for the plaza area is to provide low-level pedestrian lights (recessed wall lights and/or bollard lights) that give a safe light level for night use. Additionally, there would be accent lighting in the planters to illuminate the courtyard trees. Non-emergency lighting would be on automatic shut-off timers and lighting would be on motion-activated sensors where appropriate. Streetlights would be installed per City Engineering Standards, and the approved conceptual Downtown Lighting Plan (for streetlights along Monterey Street).

After five years, the trees would be expected to achieve heights in the range of 16 to 30 feet tall. Existing trees, including the fern pine and oak on the corner of Monterey and Nipomo streets and the large oak tree on Monterey Street would remain. In addition, landscaping would include drought-tolerant shrub planters along the pedestrian plaza/walkways. Landscape irrigation would be designed to minimize the use of water and meet all water conservation practices required by the City’s Municipal Code. Utilities Water, firewater, and wastewater service for the project would be provided by the City via adjacent main lines that surround the project site. No utility extensions would be required. Project Objectives 2.5.1 Objectives for this project include the following:  Provide a minimum of 400 parking spaces  Accommodate cultural uses on Monterey Street in front of the structure  Include a pedestrian-level public use plaza area at the corner of Nipomo and Monterey Streets  Provide a direct pedestrian connection from the structure to Monterey Street  Preserve the large oak tree on site  Consider contextual sensitivity of surrounding properties (e.g., Lattimer-Hayes adobe) Required Approvals 2.5.2 The following approvals would be required for the project:  General Plan Amendment. Amend General Plan Land Use Map from Office and Medium-High Density Residential to Public  Zone Change. Amend Zoning Map from Office with Historic Overlay (O-H) and Medium-High Density Residential to Public Facility with a Historic Overlay (PF-H)  Planning Commission Use Permit.

Including both Cultural Heritage Committee and Architectural Review Commission review In addition, the following approval would be required:  Regional Water Quality Control Board – National Pollutant Discharge Elimination System Permit 4 Zoning Regulations Table 9: Subsection 6. Parking as a principal use. Use Permit approval may include deviations to otherwise applicable setback requirements and building height limits. A multi-level parking facility shall require the approval of a Use Permit by the Planning Commission. Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 59 4.2 Cultural and Tribal Cultural Resources This section analyzes potential impacts to cultural and tribal resources as a result of the proposed project. The analysis is based on the 2011 Cultural Resources Study prepared by Applied Earthworks (Appendix C). Setting 4.2.1 a. Environmental Setting Prehistoric Setting The project site is located in what is described generally as the Central Coast archaeological region, one of eight organizational divisions of California (Jones and Klar 2007, Moratto 1984). The Central Coast archaeological region extends from Monterey Bay to Morro Bay, and includes the County of San Luis Obispo. The prehistoric cultural chronology for the Central Coast is generally divided into six periods: Paleoindian (ca. 10,000–6,000 B.C.), Millingstone (6,000–3,000 B.C.), Early and Early-Middle Transition (3,000–600 B.C.), Middle (600 B.C. - A.D. 1000), Middle-Late Transition (A.D. 1000–A.D. 1250), and Late (A.D. 1250–historic contact [ca. A.D. 1769]) (Jones and Klar 2007). Several chronological sequences have been devised to understand cultural changes along the Central Coast from the Millingstone Period to contact. Jones (1993) and Jones and Waugh (1995) presented a Central Coast sequence that integrates data from archaeological studies conducted since the 1980s. Three periods, including the Early, Middle, and Late periods, are presented in their prehistoric sequence subsequent to the Millingstone Period. More recently, Jones and Ferneau (2002) updated the sequence following the Millingstone Period as follows: Early, Early-Middle Transition, Middle, Middle-Late Transition, and Late periods. The archaeology of the Central Coast subsequent to the Millingstone Period is distinct from that of the Bay Area to the north and Central Valley to the east. The region has more in common with the Santa Barbara Channel area during the Middle and Middle-Late Transition periods, but few similarities during the Late period (Jones and Ferneau 2002). Historic Setting Post-European contact history for California is divided generally into three periods: the Spanish Period (1769–1822), the Mexican Period (1822–1848), and the American Period (1848–present). The Spanish Period brought the establishment of the California mission system, while the Mexican Period is largely known for the division of the land of California into private land holdings. Following the Mexican-American war, the United States purchased California from Mexico; population of the state subsequently increased, particularly during the Gold Rush. Following the arrival of the first Europeans, Padre Junipero Serra founded Mission San Luis Obispo de Tolosa in 1772. The population of native people at the mission declined rapidly. In 1803, there was a peak of 919 Native Americans residing at the mission, but by 1838 the population had declined to 170. In 1822, California became a Mexican Territory, and the mission lands gradually became private ranchos through Mexican land grants. In 1846, the Bear Flag Rebellion resulted in California’s independence from Mexico, and control of the territory soon fell into the hands of the United States. City of San Luis Obispo Palm Nipomo Parking Structure Project 60 The City of San Luis Obispo was incorporated in 1876 (Angel 1883). The city’s early development is closely associated with Mission San Luis Obispo de Tolosa, the Coast Line Stage which carried U.S. mail for Wells Fargo and Company through San Luis Obispo to points north and south of the City, and the pacific railway which made San Luis Obispo the commercial center of the region and provided access for passenger steamer service (Kocher 1972; Tognazzini 1993; Cooper 1875; Angel 1883). The completion of the mainline Southern Pacific rail line allowed travel and shipment of goods with greater opportunities for selling and buying commodities. The establishment of California Polytechnic State University in 1903 as a vocational school on 281 acres was also a significant draw for the city. Later development was driven by the completion of U.S. Highway 101 as San Luis Obispo was a prime location for travelers to rest on the long trip from San Francisco to Los Angeles and the establishment of the nearby military base at Camp San Luis Obispo (City of San Luis Obispo 1983; Krieger 1988; Palmer et al. 2001). Beginning in 1945, following the end of World War II, San Luis Obispo experienced a period of modernization in the second half of the twentieth century, mainly due to returning soldiers. The influx of new commerce required new development, with older buildings demolished to make way for more modern structures and parking lots. Many of the older buildings demolished were residential homes. City landmarks and many remaining adobes were lost during this period. Growth required an influx of parking to accommodate downtown customers. Many city surface parking lots were established in the downtown, including the one on the current project. Project Site Historic Context Properties lining Monterey and Higuera streets between Nipomo and Santa Rosa streets were rapidly developed in the 1860s for both commercial and residential purposes. The Harris and Ward Map established Block 9, bounded by Palm, Broad, Monterey, and Nipomo streets, divided into six lots. The project site encompasses Lots 1 and 2 whose owners were identified as: Lot 1, illegible and Lot 2, Roberto Villa. Roberto Villa presented a Petition for Grant for Lot 2 in 1870. He had settled on the land in 1855 and his property and a solitary structure appear on an 1859 petition for land that also depicts a fence on Lot 1 (at the corner of Palm and Nipomo Streets). By 1874, the project site had been divided into three lots (Applied EarthWorks 2011). During the last quarter of the nineteenth century, the project area experienced little change while Monterey Street, to the east, continued to develop with commercial and residential infill. Within the project area, dwellings at 610, 614, and 630 Monterey Street exhibited small additions to the rears of the buildings. The 1886, 1888, and 1891 Sanborn Maps show three residences within the project area, including an outhouse at the rear of the adobe on Lot 3. James Moore operated a dyeing and cleaning business in a shed at 614 Monterey Street. Three small ancillary buildings and one a shed were present at 610 Monterey Street. All of the buildings are no longer present on the project site. Shortly after the turn of the twentieth century, the city began improving streets by grading roads and filling in low places with gravel, and new development followed these improvements. Within the project area, a house was constructed in Lot 1 along with an outhouse or shed. During this same time, James Moore moved his dyeing and cleaning business from 614 Monterey Street to 610 Monterey Street. By the 1930s, the structures at 610 and 614 Monterey Street were demolished and new residences were constructed in their place in 1937 and 1933, respectively. By 1957, the house on Lot 1 was moved to the south of the lot and a welding shop was constructed in its place. New surface parking lots established in the 1960s and 1970s frequently replaced older buildings and historic uses of the properties. Within the project site, two dwellings and the welding shop were demolished to make room for the parking lot that exists today. Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 61 Documented Cultural Resources This section is based on the results of the 2011 Cultural Resources Study (Appendix C) and 2017 updated records search, of which the methods are further described in section 4.2.2(a) below. Archaeological Resources The results of the records searches identify the presence of one archaeological site within the project site (CA-SLO-2341H) and two archaeological sites adjacent to the project site (CA-SLO- 1890/H and CA-SLO-2206H). Resource CA-SLO-2341H was identified in 2003 during a citywide water line installation project and consists of a series of historic archaeological features. The nearest component of CA-SLO-2341H to the current project site was a black powder flask (1790-1860) located at the intersection of Palm and Nipomo streets adjacent to the current project site. Resources CA-SLO-1890/H and CA-SLO-2206H both consist of historic refuse deposits. Resource CA- SLO-1890/H also includes a historic house and the remnants of an adobe structure. The site record also suggests that the archaeological site contains a prehistoric component, but no discussion is given for such remains and the site is described as containing “virtually no pre-1880 refuse.” The results of the records search further identified studies conducted by Bertrando and Bertrando within the project area that consisted of archaeological testing within the project area in 1997 and in 1999. The testing conducted in 1997 identified historical material in the upper 12 inches of soil. The testing conducted in 1999 identified the remains of the rock foundation of a house constructed circa 1905 and additional historic artifacts including glass, ceramics, nails, shell, and ceramic roof tiles all thought to be associated with the house and with a welding shop (1926–1996) that was located on the property. As part of the 2011 Cultural Resources Study, Applied Earthworks staff also conducted a pedestrian survey of the project site for archaeological and architectural resources. The project area has very little exposed ground surface, though narrow strips of exposed soil are present along the Monterey Street boundary of the project site which contained historic-period debris, including glass, ceramic fragments, ferrous metal items, and shell. The study concluded that it is likely that subsurface cultural remains are intact. Built Environment Resources The project site is partially located within the Downtown Historic District, which was locally designated in 1987, and is therefore considered a historical resource under CEQA. Figure 3 shows the boundaries of the Downtown Historic District relative to the project site. The Downtown Historic District extends east from U.S. Highway 101 and Dana Street to just beyond Osos Street, and runs north from Marsh Street to Palm Street. It contains many of the city’s most important historic buildings, and while they are primarily commercial, there is also a small subsection of residential properties largely concentrated west of Broad Street, in the project area. The buildings on the north side of Monterey Street create a historic streetscape that connects the area west of Mission Plaza to the westernmost section of the Downtown Historic District on Dana Street. In this area, the historic district transitions from commercial to residential, which is a physical characteristic of the district that helps conveys the reasons for its significance. The City maintains a Master List of Historic Resources, which identifies buildings that are considered historically significant on their own merits, and a List of Contributing Historic Resources, which identifies structures that contribute to the significance of designated historic districts, although they City of San Luis Obispo Palm Nipomo Parking Structure Project 62 may not be individually significant. In general, buildings within the district display a variety of architectural styles but are primarily one to two stories in height and 50 to 75 feet in width. Two Master List properties and two contributing properties lie within or adjacent to the current project area (Table 5). The single-story vernacular residence with a detached garage at 610 Monterey Street, located on the project site, is a contributing property built in 1937 by Klien Williams. Although the 2011 Cultural Resources Study recommended it as ineligible for the CRHR and local listing, it is currently listed as a contributor to the Downtown Historic District and is thus considered a historical resource for the purposes of CEQA. The single-story, mission-influenced vernacular residence at 614 Monterey Street, located on the project site, was built by Louis R. Heyd in 1935 and is also is a contributing property to the Downtown Historic District. The 2011 Cultural Resources Study identified this property as being eligible for local listing on the City’s Master List because of its rarity and its representation of the vernacular renewal of adobe architecture prior to World War II. The property is therefore considered a historical resource for the purposes of CEQA. The Hays-Lattimer adobe is a Master List property located immediately adjacent to the east of the project site at 638-642 Monterey Street. Constructed in 1860, the property contains a weather- boarded single-story adobe residence. The two-story Harmony Creamery at 991 Nipomo Street, also located adjacent to the project site, is another Master List property. Built in 1930 by the Harmony Valley Creamer Association, it is Spanish Colonial Revival in style. The residential buildings on the project site located at 633 and 633 ½ Palm Street are located just outside the City’s Downtown Historic District. They were each recommended ineligible for listing on the CRHR and local listing, and were not found to qualify as contributing resources to the Downtown Historic District; neither is considered a historical resource under CEQA as a result. Table 5 Designated Historic Buildings Within and Adjacent to the Project Site Address Local Designation Location Relative to Project Site 610 Monterey Street Contributing property to Downtown Historic District Within 614 Monterey Street Contributing property to Downtown Historic District Within 638-342 Monterey Street (Hays-Lattimer Adobe) On Master List of Historic Resources, Downtown Historic District Adjacent 991 Nipomo Street (Harmony Creamery) On Master List of Historic Resources, Downtown Historic District Adjacent Paleontological Setting The project site lies between the San Lucia Mountains and the San Luis Mountains in the Coast Ranges geomorphic province. The Coast Ranges are northwest-trending mountain ranges and valleys that run along the Pacific coast from Santa Barbara to the Oregon border (Norris and Webb, 1990). The Coast Ranges record a thick sequence of sedimentary strata dating back to the Mesozoic Franciscan Melange (~251 million years ago), with granitic and metamorphic rocks of the Salinian block present in the southern Coast Ranges, where the project is located (Norris and Webb 1990). Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 63 The Franciscan Melange records deposition of volcanic and clastic sediments into a subduction zone during the Mesozoic era, followed by subsequent metamorphism (Wakabayashi 1992). The Franciscan Melange is known to contain a wide range of fossils, including radiolarians, mollusks, diatoms, foraminifers, and marine vertebrates (Schlocker 1974; Elder 2015; Hilton 2003). A search of the University of California Museum of Paleontology (UCMP) online collection records shows that fossils of all of these organisms have been recovered from Franciscan rocks in and around San Luis Obispo County (UCMP 2017). The most impressive of these fossils is a large marine reptile, Plesiosaur hesternus, recovered from Oakley Ranch (Hilton 2003). More recently, the Pleistocene history of the region (2.6 million–10,000 years ago) is marked by glacially controlled sea level fluctuations and tectonic uplift during which the shoreline advanced and retreated as much as 30 miles across the continental shelf (Hall 2007). Sea level advance cut a system of marine terraces, 12 of which are exposed in the Point San Luis area eight to nine miles southwest of the city. These terraces range in age from 83,000 to 49,000 years, and reach elevations of 79 feet above modern sea level. The formations that compose these terraces are the most paleontologically productive in the region (City of San Luis Obispo 2014). Jefferson et al. (1992) reported three vertebrate localities along the coast within nine miles of San Luis Obispo. These localities occur in Pleistocene fluvial deposits overlying marine terraces, and include assemblages of the Rancholabrean mammals Equus sp. and E. occidentalis (horse); Camelops sp. and C. hesternus (camel); Bison antiquus and B. latifrons (bison), and Mammut americanum (mammoth). Other localities in San Luis Obispo County are noted as well (UCMP 2017). b. Regulatory Setting The primary applicable federal and state laws and regulations protecting cultural resources are the National Historic Preservation Act, as amended, CEQA, and California Public Resources Code (Cal. Public Res. Code) §§5024.1 and 21084.1. These and other federal, state, and local laws and regulations and ordinances that pertain to cultural resources are described below. Federal The project does not involve federal funding or permitting, and as a result, does not have a federal nexus. Therefore, compliance with reference to the National Historic Preservation Act (NHPA) of 1966 and other federal laws is provided here for informational purposes only. National Historic Preservation Act [16 United States Code (U.S.C.) Section 470 et seq.] The NHPA establishes the federal government policy on historic preservation and the programs, including the National Register of Historic Places (NRHP), through which this policy is implemented. Under the NHPA, significant cultural resources, referred to as “historic properties,” include any prehistoric or historic district, site, building, structure, or object included in, or determined eligible for inclusion in, the NRHP. Historic properties also include resources determined to be National Historic Landmarks. National Historic Landmarks are nationally significant historic places designated by the Secretary of the Interior because they possess exceptional value or quality in illustrating or interpreting United States heritage. A property is considered historically significant if it meets one of the NRHP criteria and retains sufficient historic integrity to convey its significance. This act also established the Advisory Council on Historic Preservation, an independent federal agency that administers Section 106 of the NHPA by developing procedures to protect cultural resources City of San Luis Obispo Palm Nipomo Parking Structure Project 64 included in, or eligible for inclusion in, the NRHP. Regulations are published in 36 Code of Federal Regulations (C.F.R.) Parts 60, 63, and 800. Archaeological Resources Protection Act (ARPA) [16 U.S.C. 470] This statute was enacted to secure, for the present and future benefit of the American people, the protection of archaeological resources and sites which are on public lands and Indian lands. It was also enacted to foster increased cooperation and exchange of information between governmental authorities, the professional archaeological community, and private individuals (Sec. 2(4)(b)). State California Environmental Quality Act, Public Resources Code §21083.2 and California Code of Regulations (CCR), Title 14, §15064.5 CEQA requires a lead agency to consider the effects of a project on historical resources (Cal. Public Res. Code §21084.1). The CEQA Guidelines §15064.5(b) provides specific guidance for determining the significance of impacts on historical resources and unique archaeological resources (CEQA Guidelines §15064.5(b) and Cal. Public Res. Code §21083.2). Under CEQA, these resources are called “historical resources” whether they are of historic or prehistoric age. Public Resources Code §21084.1 defines historical resources as those listed, or eligible for listing, in the California Register of Historical Resources (CRHR), or those listed in the historical register of a local jurisdiction (county or city) unless the preponderance of the evidence demonstrates that the resource is not historically or culturally significant. NRHP-listed “historic properties” located in California are considered historical resources for the purposes of CEQA and are also listed in the CRHR. The CRHR criteria for listing such resources are based on, and are very similar to, the NRHP criteria. Cal. Public Res. Code §21083.2 and CEQA Guidelines §15064.5(c) provide further definitions and guidance for archaeological sites and their treatment. Different legal rules apply to the two different categories of cultural resources, though the two categories sometimes overlap where a “unique archaeological resource” also qualifies as a “historical resource.” In such an instance, the more stringent rules for the protection of archaeological resources that are historical resources apply. CEQA Guidelines §15064.5 also prescribes a process and procedures for addressing the existence of, or probable likelihood, of Native American human remains, as well as the unexpected discovery of any human remains during implementation of a project. This includes consultations with appropriate Native American tribes. The CEQA Guidelines define procedures, types of activities, persons, and public agencies required to comply with CEQA. CEQA Guidelines §15064.5(b) prescribes that project effects that would “cause a substantial adverse change in the significance of an historical resource” are significant effects on the environment. Substantial adverse changes include physical changes to both the historical resource and its immediate surroundings. Section 15126.4(a)(1) states that an EIR shall describe feasible measures which could minimize significant adverse impacts. Section 15126.5(b) describes mitigation measures related to impacts on historical resources. CEQA also requires that public agencies and private interests identify the potential environmental consequences of their proposed projects on any object or site considered to be a historical resource Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 65 of California, including paleontological resources (Cal. Public Res. Code §21084.1, CCR Title 14, §15064.5). California Register of Historical Resources (Cal. Public Res. Code §5024.1 and 14 CCR §4850) Cal. Public Res. Code §5024.1 establishes the CRHR, which lists all California properties considered to be significant historical resources. The CRHR also includes all properties listed or determined eligible for listing in the NRHP, including properties evaluated and determined eligible under §106. The criteria for listing on the CRHR, criteria 1–4, are similar to those of the NRHP: [Resources that are] associated with events that have made a significant contribution to the 1. broad patterns of California’s history and cultural heritage [Resources that are] associated with the lives of persons important in our past 2. [Resources that] embody the distinctive characteristics of a type, period, region, or method of 3. construction, or represents the work of an important creative individual, or possesses high artistic value [Resources that have] yielded, or may be likely to yield, information important in prehistory or 4. history The CRHR regulations govern the nomination of resources to the CRHR (14 CCR §4850). The regulations set forth the criteria for eligibility as well as guidelines for assessing historical integrity and resources that have special considerations. California Public Resources Code Cal. Public Res. Code also protects paleontological resources in specific contexts. In particular, Cal. Public Res. Code §5097.5 prohibits “knowing and willful” excavation, removal, destruction, injury, and defacement of any paleontological feature on public lands without express authorization from the agency with jurisdiction. Violation of this prohibition is a misdemeanor and is subject to fine and/or imprisonment (Cal. Public Res. Code § 5097.5(c)), and persons convicted of such a violation may also be required to provide restitution (Cal. Public Res. Code § 5097.5(d)(1)). Additionally, Cal. Public Res. Code §30244 requires “reasonable mitigation measures” to address impacts on paleontological resources identified by the State Historic Preservation Officer. Section 5097.5 of the Cal. Public Res. Code states: “No person shall knowingly and willfully excavate upon, or remove, destroy, injure or deface any historic or prehistoric ruins, burial grounds, archaeological or vertebrate paleontological site, including fossilized footprints, inscriptions made by human agency, or any other archaeological, paleontological or historical feature, situated on public lands, except with the express permission of the public agency having jurisdiction over such lands. Violation of this section is a misdemeanor.” As used in this Cal. Public Res. Code section, “public lands” means lands owned by, or under the jurisdiction of, the state or any city, county, district, authority, or public corporation, or any agency thereof. Consequently, local agencies are required to comply with Cal. Public Res. Code §5097.5 for their own activities, including construction and maintenance, as well as for permit actions (e.g., encroachment permits) undertaken by others. City of San Luis Obispo Palm Nipomo Parking Structure Project 66 Codes Governing Human Remains Section 15064.5 of the CEQA Guidelines also assigns special importance to human remains and specifies procedures to be used when Native American remains are discovered. The disposition of human remains is governed by Health and Safety Code §7050.5 and Cal. Public Res. Code §§5097.94 and 5097.98, and falls within the jurisdiction of the NAHC. If human remains are discovered, the County Coroner must be notified within 48 hours and there should be no further disturbance to the site where the remains were found. If the remains are determined by the coroner to be Native American, the coroner is responsible for contacting the NAHC within 24 hours. The NAHC, pursuant to Cal. Public Res. Code §5097.98, will immediately notify those persons it believes to be most likely descended from the deceased Native Americans so they can inspect the burial site and make recommendations for treatment or disposal. California Tribal Cultural Resources and Consultation (Assembly Bill 52, Chapter 532) Assembly Bill (AB) 52 became law on January 1, 2015. It establishes a formal consultation process for California Indian tribes as part of CEQA and equates significant impacts on tribal cultural resources with significant environmental impacts. Several new Public Resources Codes have been written to codify the law’s requirements. Cal. Public Res. Code §21074 defines a California Native American Tribe as a tribe located in California that is on the contact list maintained by the Native American Heritage Commission. It also defines what types of resources are to be considered tribal cultural resources. Cal. Public Res. Code §21080.3.1 describes formal tribal consultation requirements; Cal. Public Res. Code §21080.3.2 provides that if the California tribe requests consultation to include project alternatives and mitigation measures, such consultation would be required; Cal. Public Res. Code §21082.3 provides that any mitigation measures agreed upon during consultation shall be recommended for inclusion in the environmental document and affirms the lead agency’s obligation to keep confidential any information obtained from a Native American tribe during the consultation process; and Cal. Public Res. Code §21083.4 provides examples of mitigation for impacts to Tribal Cultural Resources. Senate Bill 18 (Chapter 905, Statutes of 2004) Senate Bill (SB) 18 requires cities and counties to consult with Native American tribes to help protect traditional tribal cultural places through the land use planning process for general plan adoption or amendments and to specific plan adoption or amendments. Local San Luis Obispo Zoning Regulations, Chapter 17.54 Establishes the Historical Preservation Overlay Zone (H) and describes its purposes and application, allowed uses and property development standards. Historic Preservation Ordinance, San Luis Obispo Municipal Code 14.1 The City Municipal Code contains specific requirements for the demolition and relocation of structures listed in the inventory of historic resources. These requirements are stated in Municipal Code §§14.01.100 and 14.01.110. Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 67 The City Municipal Code states that the Cultural Heritage Committee (CHC) shall review and make recommendations to the City Council regarding demolition applications for structures listed in the inventory of historic resources. An application for demolition of a listed historic resource shall be approved only if the proposed demolition is found consistent with the general plan, and 1) the historic resource is a hazard to public health of safety, and repair or stabilization is not structurally feasible; or 2) denial of the application will constitute an economic hardship as described in §14.01.100(J)(1-3) of the municipal code. Additional procedures regarding the timing of the demolition, documentation and acknowledgment of the historic resource are also delineated. Likewise, the relocation of a structure listed on the inventory of historical resources is subject to review by the CHC and Architectural Review Commission (ARC). Relocation shall be permitted only when relocation is consistent with the goals and policies of the general plan, any applicable area or specific plans, and the Historic Preservation Program Guidelines, as well as additional criteria defined in Municipal Code §14.01.110(B)(1-6). The timing, plan, procedures, and documentation are also delineated. City of San Luis Obispo Municipal Code Demolition and Moving of Buildings Appendix Chapter 2, Chapter 201, of the San Luis Obispo Municipal Code, establishes procedures and requirements for the relocation or demolition of historic buildings. City of San Luis Obispo Historic Preservation Program Guidelines The guidelines establish procedures for the treatment of historic resources, including construction in historic districts and on properties with historic resources. They also include a discussion of the city’s existing historic districts and provide a summary of their significance and character-defining features. City of San Luis Obispo Archaeological Resource Preservation Program Guidelines The guidelines establish procedures to be used for the identification, evaluation, and preservation of archaeological and other cultural resources. Cultural resources refer to the artifacts, human remains, and sites containing evidence of past human activities, including prehistoric Native American archaeological sites, historic archaeological sites, sites or natural landscapes associated with important human events, and Native American sacred places and cultural landscapes. City of San Luis Obispo Community Design Guidelines The guidelines establish site and architectural design standards for development projects, including projects involving historic resources and historic districts, and demolitions. City of San Luis Obispo General Plan Conservation and Open Space Element. The Conservation and Open Space Element of the General Plan establishes citywide policies and programs regarding identification and treatment of cultural resources. The following policies apply to this project:  Policy 3.3.1 Historic Preservation. Significant historic and architectural resources should be identified, preserved, and rehabilitated.  Policy 3.3.2 Demolitions. Historically or architecturally significant buildings shall not be demolished or substantially changed in outward appearance, unless doing so is necessary to City of San Luis Obispo Palm Nipomo Parking Structure Project 68 remove a threat to health and safety and other means to eliminate or reduce the threat to acceptable levels are infeasible.  Policy 3.3.3 Historical Documentation. Buildings and other cultural features that are not historically significant but which have historical or architectural value should be preserved or relocated where feasible. Where preservation or relocation is not feasible, the resources shall be documented and the information retained in a secure but publicly accessible location. An acknowledgement of the resources should be incorporated within the site through historic signage and the reuse or display of historic material and artifacts.  Policy 3.5.1. Archaeological Resource Protection. The City shall provide for the protection of both known and potential archaeological resources. To avoid significant damage to important archaeological sites, all available measures, including purchase of the property in fee or easement, shall be explored at the time of a development proposal. Where such measures are not feasible and development would adversely affect identified archaeological or paleontological resources, mitigation shall be required pursuant to the Archaeological Resource Preservation Program Guidelines.  Policy 3.5.2. Native American Sites. All Native American cultural and archaeological sites shall be protected as open space wherever possible.  Policy 3.5.4 Archaeological Sensitive Areas. Development within an archaeologically sensitive area shall require a preliminary site survey by a qualified archaeologist knowledgeable in Native American cultures, prior to a determination of the potential environmental impacts of the project.  Policy 3.5.5 Archaeological Resources Present. Where a preliminary site survey finds substantial archaeological resources, before permitting construction, the City shall require a mitigation plan to protect the resources. Possible mitigation measures include: presence of a qualified professional during initial grading or trenching; project redesign; covering with a layer of fill; excavation removal and curation in an appropriate facility under the direction of a qualified professional.  Policy 3.5.6 Qualified Archaeologist Present. Where substantial archaeological resources are discovered during construction or grading activities, all such activities in the immediate area of the find shall cease until a qualified archaeologist knowledgeable in Native American cultures can determine the significance of the resource and recommend alternative mitigation measures.  Policy 3.5.7 Native American Participation. Native American participation shall be included in the City’s Guidelines for resource assessment and impact mitigation. Native American representatives should be present during archaeological excavation and during construction in an area likely to contain cultural resources. The Native American community shall be consulted as knowledge of cultural resources expands and as the City considered updates or significant changes to its General Plan.  Policy 3.6.3 Construction within Historic Districts. The Cultural Heritage Committee and Architectural Review Commission will provide specific guidance on the construction of new buildings within historic districts. Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 69 Impact Analysis 4.2.2 a. Methodology and Significance Thresholds Methodology Cultural Resources Methodology Direct impacts are assessed by identifying known cultural resources in the project study area, determining if any archaeological sites or historic structures are located within the project area, assessing the significance of the resources that may be affected, and determining the appropriate mitigation. Removal, demolition, or alteration of historical resources can permanently impact the historic fabric of an archaeological site, structure, or historic district. As previously mentioned, in 2011 Applied Earthworks prepared a Cultural Resources Study of the project site and vicinity (Appendix C). The study involved a records search at the Central Coast Information Center of the California Historical Resources Information System at the University of California Santa Barbara, archival and historical research, field survey of the property, predictive modeling of archaeological resources, evaluation of any potentially significant historic structures on the property, and assessment of potential impacts to the surrounding Downtown Historic District. The records search was conducted to identify previous cultural resources evaluations and previously recorded cultural resources on the project site as well as within a 200-foot radius of the project site. The archival research focused on the review of primary and secondary source materials related to the history and development of the project site and vicinity. Sources examined during the records and archival search included maps pinpointing cultural resources locations, survey coverage maps, site record and report files, city directories, Great Registers, historical maps, and newspapers. The State Historic Property Data Files, National Register of Historic Places, National Register of Determined Eligible Properties, California Points of Historic Interest, California Office of Historic Preservation Archaeological Determinations of Eligibility, and the California Department of Transportation State and Local Bridge Surveys were also analyzed. The results of the records search further identified studies conducted by Bertrando and Bertrando within the project site that consisted of archaeological testing in 1997 and 1999. In 2017, Rincon Consultants conducted an updated records search to expand the radius to 0.25-mile and to identify any cultural resources recorded since 2011. Archaeological sites and historic structures located within the project area are described in Section 4.2.1, Setting. Native American Consultation The City conducted Native American consultation consistent with Senate Bill 18 and Assembly Bill 52 for the project to identify potential concerns or issues associated with Native American cultural resources near the project. Rincon contacted the NAHC to determine if any sites recorded in the NAHC’s Sacred Lands File occur in or near the project site. The NAHC responded on May 1, 2017 that the search of the sacred land files for the USGS quadrangle in which the project is located “provided negative results” (citation). The NAHC did provide a list of Native American tribes with traditional lands or cultural places in the project area that may have knowledge of cultural resources at the project site. The Native American scoping did not identify any specific resources important to the consulted groups in or near the project site. However, Patti Dunton of the Salinan Tribe of Monterey City of San Luis Obispo Palm Nipomo Parking Structure Project 70 and San Luis Obispo Counties noted that the project site is sensitive for cultural resources and requested an archaeological survey of the project area before and after the asphalt is removed. She asked that if resources are identified that all further ground-disturbing areas be monitored by a cultural resources specialist from the Salinan Tribe. Native American correspondence can be found in Appendix C. Paleontological Resources Methodology Rincon Consultants paleontologists evaluated the paleontological sensitivity of the geologic units present on the project site based on a review of existing information in the primary literature on known fossils within those geologic units, review of previous geotechnical studies of the project site, and consultation of the online database maintained by the University of California Museum of Paleontology (UCMP) for fossil localities in San Luis Obispo County recorded from geologic units present in the project site. Rincon Consultants’ paleontologists assigned paleontological sensitivity to each geologic unit within the project site. The potential for impacts to significant paleontological resources is based on the potential for ground disturbance to directly impact paleontologically sensitive geologic units. Paleontological sensitivity is defined by the Society of Vertebrate Paleontology (SVP). The SVP broadly defines significant paleontological resources as follows (SVP 2010:11): “Fossils and fossiliferous deposits consisting of identifiable vertebrate fossils, large or small, uncommon invertebrate, plant, and trace fossils, and other data that provide taphonomic, taxonomic, phylogenetic, paleoecologic, stratigraphic, and/or biochronologic information. Paleontological resources are considered to be older than recorded human history and/or older than middle Holocene (i.e., older than about 5,000 radiocarbon years).” Significant paleontological resources are determined to be fossils or assemblages of fossils that are unique, unusual, rare, diagnostically important, or are common but have the potential to provide valuable scientific information for evaluating evolutionary patterns and processes, or which could improve our understanding of paleochronology, paleoecology, paleophylogeography, or depositional histories. New or unique specimens can provide new insights into evolutionary history; however, additional specimens of even well represented lineages can be equally important for studying evolutionary pattern and process, evolutionary rates, and paleophylogeography. Even unidentifiable material can provide useful data for dating geologic units if radiocarbon dating is possible. As such, common fossils (especially vertebrates) may be scientifically important, and therefore considered highly significant. The SVP (2010) describes sedimentary rock units as having high, low, undetermined, or no potential for containing significant nonrenewable paleontological resources. This criterion is based on rock units within which vertebrate or significant invertebrate fossils have been determined by previous studies to be present or likely to be present. While these standards were specifically written to protect vertebrate paleontological resources, all fields of paleontology have adopted these guidelines: I. HIGH POTENTIAL (SENSITIVITY) Rock units from which significant vertebrate or significant invertebrate fossils or significant suites of plant fossils have been recovered are considered to have a high potential for containing significant non-renewable fossiliferous resources. These units include but are not limited to, sedimentary formations and some volcanic formations which contain significant nonrenewable paleontological Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 71 resources anywhere within their geographical extent, and sedimentary rock units temporally or lithologically suitable for the preservation of fossils. Sensitivity comprises both (a) the potential for yielding abundant or significant vertebrate fossils or for yielding a few significant fossils, large or small, vertebrate, invertebrate, or botanical and (b) the importance of recovered evidence for new and significant taxonomic, phylogenetic, ecologic, or stratigraphic data. Areas which contain potentially datable organic remains older than Recent, including deposits associated with nests or middens, and areas which may contain new vertebrate deposits, traces, or trackways are also classified as significant. II. LOW POTENTIAL (SENSITIVITY) Sedimentary rock units that are potentially fossiliferous, but have not yielded fossils in the past or contain common and/or widespread invertebrate fossils of well documented and understood taphonomic, phylogenetic species and habitat ecology. Reports in the paleontological literature or field surveys by a qualified vertebrate paleontologist may allow determination that some areas or units have low potentials for yielding significant fossils prior to the start of construction. Generally, these units will be poorly represented by specimens in institutional collections and will not require protection or salvage operations. However, as excavation for construction gets underway it is possible that significant and unanticipated paleontological resources might be encountered and require a change of classification from Low to High Potential and, thus, require monitoring and mitigation if the resources are found to be significant. III. UNDETERMINED POTENTIAL (SENSITIVITY) Specific areas underlain by sedimentary rock units for which little information is available are considered to have undetermined fossiliferous potentials. Field surveys by a qualified vertebrate paleontologist to specifically determine the potentials of the rock units are required before programs of impact mitigation for such areas may be developed. IV. NO POTENTIAL Rock units of metamorphic or igneous origin are commonly classified as having no potential for containing significant paleontological resources. The loss of significant paleontological resources that meet the criteria outlined above would be considered a significant impact under CEQA, and the CEQA lead agency is responsible for ensuring that paleontological resources are protected in compliance with CEQA and other applicable statutes. Significance Thresholds If a project may cause a substantial adverse change in the characteristics of a resource that convey its significance or justify its eligibility for inclusion in the CRHR or a local register, either through demolition, destruction, relocation, alteration, or other means, then the project is judged to have a significant effect on the environment (CEQA Guidelines, §15064.5[b]). The following thresholds are based on Appendix G of the CEQA Guidelines. Impacts would be significant if the project would: Cause a substantial adverse change in the significance of a historical resource 1. Cause a substantial adverse change in the significance of an archaeological resource 2. Directly or indirectly destroy a unique paleontological resource or site or unique geologic 3. feature Disturb any human remains, including those interred outside of formal cemeteries 4. City of San Luis Obispo Palm Nipomo Parking Structure Project 72 Cause a substantial adverse change in the significance of a tribal cultural resource, defined in 5. Public Resources Code §21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is: A. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code §5020.1(k) B. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code §5024.1. In applying the criteria set forth in subdivision (c) of Public Resource Code §5024.1, the lead agency shall consider the significance of the resource to a California Native American tribe b. Project Impacts Impact CR-1N-4 CONSTRUCTION OF THE PROJECT WOULD RESULT IN THE DEMOLITION OF TWO STRUCTURES ON THE PROJECT SITE THAT ARE HISTORIC RESOURCES, AND ADVERSELY AFFECT THE DOWNTOWN HISTORIC DISTRICT. THIS WOULD CAUSE A SUBSTANTIAL ADVERSE CHANGE IN THE SIGNIFICANCE OF HISTORICAL RESOURCES AS DEFINED IN CEQA GUIDELINES §15064.5. THIS IMPACT WOULD BE CLASS I, SIGNIFICANT AND UNAVOIDABLE. The CEQA guidelines define direct impacts as direct or primary effects caused by a project at the same place, and indirect impacts as affects caused by a project but occur at a different place. The project proposes a number of actions, each of which will result in impacts to historical resources. Table 6 summarizes each of the proposed project actions and the resulting type and level of impact that would result to historical resources. Table 6 Impacts to Historical Resources Project Action Type of Impact Level of Impact Demolition of 633 and 633½ Palm Street1 Direct Less than significant Demolition of 610 Monterey Street Direct Significant Demolition of 614 Monterey Street Direct Significant New Construction Indirect/Direct Significant/Less than significant 1 As discussed above, based on the 2011 Cultural Resources Study, these structures were found to not meet the definition of historical resources under CEQA. Demolition of 633 and 633 ½ Palm Street The project would result in the demolition of the buildings at 633 and 633 ½ Palm Street. Although demolition of these buildings would be a direct impact, as discussed above, neither is considered a historical resource as defined by CEQA. Both buildings were evaluated in 2011 and found to not meet the definition of historical resources under CEQA and they are located outside the boundaries of the Downtown Historic District. Thus, their demolition would not diminish the integrity of the Downtown Historic District and would not constitute a significant impact on historical resources. Demolition of 610 Monterey Street The project would result in the demolition of the structure at 610 Monterey Street. As a contributing resource to the Downtown Historic District, this property is a historical resource as defined by CEQA. Demolition of this property is potentially inconsistent with Policies 3.3.1 and 3.3.2 Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 73 of the City’s Conservation and Open Space Element of the General Plan, and would be considered a significant adverse impact under CEQA. Demolition of 614 Monterey Street The project would result in the demolition of the structure at 614 Monterey Street. As both a contributing resource to the Downtown Historic District and a property that was found individually eligible for local designation in 2011, this property is a historical resource as defined by CEQA. Demolition of this property is potentially inconsistent with Policies 3.3.1 and 3.3.2 of the City’s Conservation and Open Space Element of the General Plan, and would be considered a significant adverse impact under CEQA. New Construction The project has the potential to result in direct and indirect impacts to historical resources, specifically the Downtown Historic District, the adjacent locally-designated Hays-Lattimer Adobe located at 638-642 Monterey Street, and the locally-designated Harmony Creamery at 991 Nipomo Street. In consideration of these potential impacts this analysis follows the guidance of the City of San Luis Obispo’s Historic Preservation Program Guidelines, which states “construction in historic districts and on properties that contain listed historic resources shall conform with the goals and policies of the General Plan, the Historic Preservation Ordinance, these Guidelines, the Community Design Guidelines, any applicable specific or area plan, and the Secretary of the Interior’s Standards for the Treatment of Historic Properties (City of San Luis Obispo 2010:6). The City of San Luis Obispo’s Historic Preservation Program Guidelines state “new structures in historic districts shall be designed to be architecturally compatible with the district’s prevailing historic character as measured by their consistency with the scale, massing, rhythm, signature architectural elements, exterior materials, siting, and street yard setbacks of the districts historic structures” (City of San Luis Obispo 2010:7). Further guidance is provided in the Secretary of the Interior’s Standards for the Treatment of Historic Properties, which is recognized by CEQA as mitigating potential adverse impacts caused by a project to below the level of significance. According to the Secretary of the Interior’s Standards, new construction in or near historic properties, including districts, should be differentiated but compatible; attention should be devoted to ensuring that the new construction is complementary to the historic property but does not create a false sense of history by imitating or replicating a historic building or property. The Secretary of the Interior’s Standards include setting, in terms of the character of the surrounding environment, as a character-defining feature that weighs in the analysis of a resource’s retention of historic integrity. The proposed project would adversely affect the Downtown Historic District by inserting a new visual feature that is inconsistent with the height, scale, and massing of the resources that characterize the historic district. As described in the setting above, these resources within the district are primarily one to two stories in height and 50 to 75 feet in width. Although the commercial space and non-profit theater would be 41 to 43 feet high, the maximum height of the project would be 50 feet. The project would also have an approximately 200 x 200 square foot floor area. This is substantially taller and wider than the other adjacent historic resources, and would interrupt the rhythm and overall setting of the district. The parking structure and commercial space would be designed in a Spanish Colonial architectural style that is compatible with the surrounding historic properties; however, the theater would be Modernistic in style. The project would be visible from the contributing properties along Dana Street, adjacent Hays-Lattimer adobe, and Harmony City of San Luis Obispo Palm Nipomo Parking Structure Project 74 Creamery, and the visual impacts of the project may reach as far as the Dr. George B. Nichols House at 664 Monterey Street, the Carnegie Library at 696 Monterey Street, and the San Luis Obispo de Tolosa Mission, all Master List Properties. Since the designation of the Downtown Historic District in 1987, Nipomo Street between Higuera and Palm streets has sustained several other changes to historic character. Three buildings were removed (one relocated outside of the district) for the creation of the existing parking area at Palm and Nipomo street in 1997. The new Children’s Museum at the corner of Nipomo and Monterey streets is modern in appearance and inconsistent with the architecture of the surrounding properties. The new Soda Water Works building was also constructed with a modern appearance. Both of these properties are inside the Downtown Historic District boundaries but are no longer contributing resources. The project would further result in direct impacts to the Downtown Historic District by removing two contributing structures and introducing new, nonconforming structures. This would physically and visually disconnect the contributing historic resources on Dana Street5 from the remainder of the district to the east, resulting in a loss of integrity of the historic district. The proposed project would also interrupt the transition from commercial to residential that occurs in this area of the historic district, which is a physical characteristic of the district that helps conveys the reasons for its significance. As a result, the proposed project would result in a significant adverse impact to the Downtown Historic District. As described above, the Hays-Lattimer adobe is located immediately adjacent to the east of the project site and is a historical resource for the purposes of CEQA. Project construction activities would generate groundborne vibration that has the potential to result in damage to the historic adobe building. The Federal Transit Administration (FTA) thresholds for damage to fragile historic buildings, state that vibration impacts would be significant if vibration exceeds 88 VdB. As discussed in Section 4.3, Noise, the project would not generate vibration levels higher than 87 VdB at a distance of 25 feet. The adobe structure is approximately 60 feet from where construction of the nearest structure would occur. Direct impacts to the Hays-Lattimer adobe from groundborne vibration would therefore be less than significant. As noted above, the Secretary of the Interior’s Standards include setting, in terms of the character of the surrounding environment, as a character-defining feature that weighs in the analysis of a resource’s retention of historic integrity. The setting of the Hays-Lattimer and Harmony Creamery is consistent with the larger Downtown Historic District and is characterized by one to two-story buildings that are approximately 50 to 75 feet wide. Although the commercial building along Nipomo Street and the theater along Monterey Street would be lower (approximately 41 to 43 feet tall) than the parking structure, the proposed project as a whole is substantially larger in its scale, massing, and height and would alter the surrounding setting of both historical resources. Although this change would negatively affect their historic integrity, both would continue to convey the reasons for their significance. Indirect impacts to the Hays-Lattimer adobe and Harmony Creamery would therefore be less than significant. Mitigation Measures The following mitigation measure is required. 5 The Dana Street group is a small subsection of residential properties within the otherwise commercial Downtown Historic Distr ict, which is representative of the early residential settlement of downtown San Luis Obispo and contributes to the significance of the district. Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 75 CR-1 Historic Building Documentation Packages Impacts to historical resources shall be minimized through the preparation of archival historic building documentation packages for both 610 and 614 Monterey Street. Prior to issuance of demolition permits, the City of San Luis Obispo shall ensure that documentation of both properties is completed in the form of a Historic American Building Survey (HABS)-Like documentation that shall comply with the Secretary of the Interior’s Standards for Architectural and Engineering Documentation (NPS 1990). The documentation shall generally follow the HABS Level III requirements and include high-quality digital photographic recordation of the buildings and their overall setting, detailed historic narrative report, and compilation of historic research. The documentation shall be completed by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). Individual archival documentation packages shall be completed for both properties and offered as donated material to the San Luis Obispo Library and the History Center of San Luis Obispo County, where it would be available to local researchers. PLAN REQUIREMENTS AND TIMING The City shall complete archival documentation of the 610 and 614 Monterey Street properties to the issuance of project grading permits. MONITORING The Community Development Director shall confirm completion of and approve the archival documentation. The City shall confirm submittal of the documentation to the History Center of San Luis Obispo County and the San Luis Obispo County Library. Significance After Mitigation Mitigation Measure CR-1 would reduce impacts to historical resources to the greatest extent possible; however, this measure would not eliminate the permanent impacts to the identified historic resources, and no other feasible mitigation measures are available. Therefore, the project would result in a significant and unavoidable impact to historic resources. Impact CR-2N-5 CONSTRUCTION OF THE PROJECT WOULD RESULT IN GROUND DISTURBANCE THAT COULD CAUSE A SUBSTANTIAL ADVERSE CHANGE IN THE SIGNIFICANCE OF AN ARCHAEOLOGICAL RESOURCE AS DEFINED IN CEQA GUIDELINES 15064. THIS IMPACT WOULD BE CLASS II, SIGNIFICANT BUT MITIGATABLE. The project site is currently developed with an asphalt parking lot and residential structures. During archaeological testing conducted in 1996 and 1999, subsurface historical archaeological materials were identified in the 0.5-acre surface parking lot at the corner of Palm and Nipomo streets within the project site. During the survey conducted for the project in 2011, historic-period debris was observed in the small amount of exposed native soils along Monterey Street. Additionally, similar work in the project vicinity has shown that subsurface archaeological deposits exist throughout the city. Approximately 0.125 mile (660 feet) from the project site, trenches uncovered a mission-era midden containing a significant Native American deposit and it is unclear whether that deposit extends to the project site. Based on the results of work within the project site and the vicinity, it is likely that additional remains related to the mission and post-mission occupation of the area are present. Additional intact subsurface deposits may be present. Therefore, construction of the project could damage or destroy archeological resources. Impacts to such resources would be City of San Luis Obispo Palm Nipomo Parking Structure Project 76 potentially significant and mitigation would be required to ensure that any discovered archaeological resources would be protected and curated if encountered during project construction activities. Mitigation Measures The following mitigation measures would reduce potential impacts to archaeological resources to a less than significant level. CR-2(a) Retain a Qualified Principal Investigator A qualified principal investigator, defined as an archaeologist who meets the Secretary of the Interior’s Standards for professional archaeology (hereafter qualified archaeologist), shall be retained to carry out all mitigation measures related to archaeological resources. CR-2(b) City of San Luis Obispo Consolidated Approach for Archaeological Investigations Mitigation of archaeological resources within the project area shall follow the Consolidated Approach as outlined in the City of San Luis Obispo Archaeological Resource Preservation Program Guidelines. The Consolidated Approach shall include (1) the preparation of a Research Design and Mitigation Plan prepared by the qualified archaeologist and submitted for written approval to the City’s Community Development Director (Director), which shall include but not be limited to the research design, laboratory and field methods, public interpretation, and location of curation; (2) monitoring of demolition and clearing of pavement within the project area; (3) fieldwork after the removal of pavement consisting of a Phase I inventory, Phase 2 Testing and Evaluation, and Phase 3 Data Recovery aimed at locating archaeological remains, evaluating their significance and integrity, and mitigating impacts through data recovery excavation; (4) the completion of special studies, such as faunal analysis, if appropriate, and the curation of recovered artifacts; and (5) the completion of a technical report documenting the results of the consolidated approach prepared in accordance with current professional standards and submitted to the Director. CR-2(c) Archaeological Monitoring An archaeological monitor shall be present for all project-related ground-disturbing construction activities. The monitor(s) shall be onsite on a full-time basis during earthmoving activities within native soils, including grading, trenching, vegetation removal, or other excavation activities. Under consultation between the qualified archaeologist and the City, monitoring may be reduced or eliminated based on observed conditions. CR-2(d) Unanticipated Discovery of Archaeological Resources In the event that cultural resources are encountered during the implementation of Mitigation Measures CR-2(b) or CR-2(c), all work shall be halted in the vicinity of the discovery until a qualified archaeologist can assess the significance of the resource. If the resources are found to be significant, they must be avoided or mitigated pursuant to the qualified archaeologist’s direction and the testing plan outlined under Mitigation Measure CR-2(b). Mitigation may involve preservation in place or documentation and excavation of the resource. A report by the archaeologist evaluating the find and identifying mitigation actions taken shall be submitted to the City. Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 77 PLAN REQUIREMENTS AND TIMING The City shall retain a qualified archaeologist prior to the issuance of demolition and grading permits. The qualified archaeologist shall prepare and submit the Research Design and Testing and Mitigation Plan prior to the issuance of demolition and grading permits. All fieldwork conducted under the consolidated approach must be completed prior to the issuance of grading permits. The requirement that ground disturbance be observed by an archaeological monitor and that construction work be stopped in the event of discovery of archaeological resources shall be included on construction plans prior to the issuance of grading permits. MONITORING The City shall review construction plans and periodically inspect project construction to ensure compliance with this measure. Significance After Mitigation Impacts to archaeological resources would be less than significant with incorporation of mitigation measures CR-2(a) through CR-2(d). Impact CR-3N-6 CONSTRUCTION OF THE PROJECT WOULD RESULT IN GROUND DISTURBANCE THAT COULD INDIRECTLY OR DIRECTLY DESTROY A UNIQUE PALEONTOLOGICAL RESOURCE. THIS IMPACT WOULD BE CLASS II, SIGNIFICANT BUT MITIGABLE. According to mapping by Dibblee and Minch (2004), the project site consists of younger Quaternary alluvium that dates to the Holocene. These sediments consist of gravel and sand deposited over the last 10,000 years by local rivers (Dibblee and Minch, 2004). Geotechnical studies have supported this mapping, and further detailed depths of 25-44 feet to bedrock, the Mesozoic Franciscan Melange, throughout the project site (Earth Systems Pacific 2011). Furthermore, Earth Systems Pacific (2011) documented some parts of the project site where artificial fill was present in the subsurface to depths of 3 and 5 feet. It should be noted that fill was only documented in two of the eight boreholes across the site, and was not present in the others (Earth Systems Pacific 2011). Using these data, as well as the paleontological literature review presented above, Rincon Consultants’ paleontologists assigned SVP paleontological sensitivities to geologic units likely to be impacted by construction in the project site. It should be noted that while the Franciscan Melange has high sensitivity, it is deep enough (20 to 44 feet) that it should not be impacted by the anticipated depths of ground disturbance (14 feet). Artificial Fill As a product of manmade activities, artificial fill has no paleontological sensitivity. Quaternary Alluvium As discussed above, Pleistocene-aged alluvial sediments have preserved fossil resources throughout California, including San Luis Obispo County. While the Quaternary alluvium mapped in the project area is too young to preserve fossils in the upper layers, it increases with age in depth. Therefore, deeper levels may be of an appropriate age to preserve fossil resources. Quaternary alluvium is thus assigned a low-to-high paleontological sensitivity, increasing with depth. While the exact depth at which this transition occurs has not been established for the project area, 10 feet is a reasonable estimate. City of San Luis Obispo Palm Nipomo Parking Structure Project 78 Because project construction has the potential to disturb sensitive geologic units, impacts would be potentially significant. Mitigation Measures The following mitigation measures would reduce potential impacts to paleontological resources to a less than significant level. CR-3(a) Retain a Qualified Project Paleontologist A qualified project paleontologist, defined as a paleontologist who meets the standards of the SVP (2010), shall be retained to carry out all mitigation measures related to paleontological resources. CR-3(b) Paleontological Worker Environmental Awareness Program (WEAP) Prior to the start of construction, the project paleontologist or his or her designee shall conduct training for construction personnel regarding the appearance of fossils and the procedures for notifying paleontological staff should fossils be discovered by construction staff. The WEAP shall be fulfilled at the time of a preconstruction meeting at which a qualified paleontologist shall attend. CR-3(c) Paleontological Monitoring Ground-disturbing construction activities (including grading, trenching, foundation work, and other excavations) in previously undisturbed sediments that exceed 10 feet in depth shall be monitored on a full-time basis during initial ground disturbance. Monitoring shall be conducted by a qualified paleontological monitor, who is defined as an individual who has experience with collection and salvage of paleontological resources and meets the minimum standards of the SVP (2010). The duration and timing of the monitoring will be determined by the project paleontologist and the location and extent of proposed ground disturbance. If the project paleontologist determines that full-time monitoring is no longer warranted, based on the specific geologic conditions at the surface or at depth, the project paleontologist may recommend that monitoring be reduced to periodic spot-checking or cease entirely. Monitoring is not necessary in artificial fill or for activities that do not reach 10 feet in depth. CR-3(d) Fossil Discoveries In the event of a fossil discovery by the paleontological monitor or construction personnel, all work in the immediate vicinity of the find shall cease. The project paleontologist shall evaluate the find before restarting construction activity in the area. If it is determined that the fossil(s) is (are) scientifically significant, the project paleontologist shall complete the following conditions to mitigate impacts to significant fossil resources: 1) Salvage of Fossils. The project paleontologist (or paleontological monitor) should recover significant fossils following standard field procedures for collecting paleontological resources, as described by the SVP (2010). Typically, fossils can be safely salvaged quickly by a single paleontologist and not disrupt construction activity. In some cases larger fossils (such as complete skeletons or large mammal fossils) require more extensive excavation and longer salvage periods. In this case the paleontologist should have the authority to temporarily direct, divert, or halt construction activity to ensure that the fossil(s) can be removed in a safe and timely manner. Environmental Impact Analysis Cultural and Tribal Cultural Resources Final Environmental Impact Report 79 2) Preparation and Curation of Recovered Fossils. Once salvaged, significant fossils should be identified to the lowest possible taxonomic level, prepared to a curation-ready condition, and curated in a scientific institution with a permanent paleontological collection (such as the University of California Museum of Paleontology), along with all pertinent field notes, photos, data, and maps. Fossils of undetermined significance at the time of collection may also warrant curation at the discretion of the project paleontologist. Significance After Mitigation Mitigation Measures CR-3(a) through CR-3(d) would reduce the potential impacts to paleontological resources to a less than significant level. Impact CR-4N-7 NO TRIBAL CULTURAL RESOURCES WERE IDENTIFIED WITHIN THE PROJECT SITE, BUT AREA IS GENERALLY CONSIDERED SENSITIVE FOR CULTURAL RESOURCES. THIS IMPACT WOULD BE CLASS III, LESS THAN SIGNIFICANT. Native American consultation efforts completed by the City pursuant to the requirements AB 52 and SB 18. The efforts under SB 18 and AB 52 did not identify specific tribal cultural resources within the project area; however, it did identify the project site as sensitive, consistent with the results of the Cultural Resources Study. As a result of the general cultural resources sensitivity of the area, Patti Dunton of the Salinan Tribe of Monterey and San Luis Obispo Counties requested that fieldwork be conducted at the project area after the removal of pavement and that project-related ground disturbance be observed by a Salinan tribal monitor. As no tribal cultural resources were identified or known to exist in the project area, the project would result in a less than significant impact on tribal cultural resources. Mitigation Measures No mitigation measures are required. Significance After Mitigation No mitigation measures are required. Impacts are less than significant. Impact CR-5N-8 GROUND-DISTURBING ACTIVITIES ASSOCIATED WITH CONSTRUCTION OF THE PROJECT HAS THE POTENTIAL TO DISTURB UNIDENTIFIED HUMAN REMAINS. THIS IMPACT WOULD BE CLASS II, SIGNIFICANT BUT MITIGABLE. Unanticipated discovery of human remains during project excavation would require compliance with Health and Safety Code §7050.5 and Cal. Public Res. Code Sections 5097.94 and 5097.98. Cal. Public Res. Code §5097.98 also addresses the disposition of Native American burials, protects such remains, and established the Native American Heritage Commission to resolve any related disputes. Compliance with Health and Safety Code §7050.5 and Cal. Public Res. Code §§ 5097.94 and 5097.98 would ensure that unanticipated discovery of human remains during project excavation, including those interred outside of formal cemeteries, would be addressed appropriately by the County Coroner and NAHC (if required). Mitigation Measures Compliance with existing regulations and mitigation measure CR-2(d) would ensure that potential impacts to human remains and burial grounds would be less than significant. City of San Luis Obispo Palm Nipomo Parking Structure Project 80 Significance After Mitigation Impacts to human burial grounds would be less than significant with implementation of mitigation measure CR-2(d). c. Cumulative Impacts Planned buildout of the City of San Luis Obispo under the General Plan would cumulatively increase the potential for adverse effects on cultural and tribal cultural resources in the city. The project would incrementally contribute to this cumulative effect. Impacts to cultural and tribal cultural resources are generally site-specific. Accordingly, as required under applicable laws and regulations, potential impacts associated with cumulative developments would be addressed on a case-by-case basis. The proposed project, as well as other cumulative projects in the city, would be required to comply with existing state and local regulations described in Section 4.2.1(b), Regulatory Setting, which address the protection of cultural and tribal cultural resources in the city. As described under Impacts CR-2, CR-3, and CR-5, with implementation of required mitigation, the project would reduce potential impacts to archaeological and/or paleontological resources to less than significant levels. In addition, as described in Impact CR-4, the project would result in a less than significant impact on tribal cultural resources. Therefore, the project would not contribute substantially to the cumulative loss of archaeological, paleontological, or tribal cultural resources in the city. However, as described in Impact CR-1, the project would result in a significant and unavoidable impact associated with the removal of two historic structures that are part of the Downtown Historic District. The project would also result in a significant and unavoidable impact on the Downtown Historic District. Mitigation measure CR-1 would reduce the project’s impacts to historical resources to the greatest extent possible; however, this measure would not eliminate the permanent cumulative or individual impacts to the identified historic resources, and no other feasible mitigation measures are available. As such, the project would contribute to the cumulative loss of historic resources in the city. This would be a Class I, significant and unavoidable, cumulative impact to historical resources.

Introduction Phase 1B & Phase 2 Mitigation and Monitoring Plan 1 1 Introduction Rincon Consultants, Inc. (Rincon) was retained by the City of San Luis Obispo (City) to provide Mitigation Monitoring and Reporting Program (MMRP) compliance services in support of Phase 1B and Phase 2 of the Cultural Arts District Parking Structure Project (formerly known as the Palm Nipomo Parking Structure) in San Luis Obispo, California. The Mitigation and Monitoring Plan (MMP) will address the details, timing, and responsibility of all required mitigation monitoring activities. The current Phase 1A of the Cultural Arts District Parking Structure Project (project) consists of undergrounding existing dry utilities in preparation for the main phases of construction. Phase 1B consists of demolition and Phase 2 consists of site preparation and construction of the parking structure and surrounding site improvements. Phase 1B and Phase 2 are subject to mitigation requirements outlined in the Final EIR for the Palm Nipomo Parking Structure Project adopted by the City Council in July 2018 (2018 Final EIR; City of San Luis Obispo 2018). The City intends to submit for building permit approval for all project phases in 2022 and intends to commence Phase 1B in Spring 2023 and Phase 2 in Fall 2023.

To reduce ROG and NOX levels during the architectural coating phase, low or no VOC- emission paint shall be used with levels of 50 g/L or less. City of San Luis Obispo Cultural Arts District Parking Structure Project 4 BIOLOGICAL RESOURCES 7. To avoid disturbance of nesting and special-status birds, activities related to the project, including, but not limited to, vegetation removal, ground disturbance, and construction and demolition shall occur outside of the bird breeding season (typically February through August in the project region). If construction must begin within the breeding season, then a pre-construction nesting bird survey shall be conducted no more than 3 days prior to initiation of ground disturbance and vegetation removal activities. The nesting bird pre-construction survey shall be conducted within the Project Boundary, including a 300-foot buffer (500-foot for raptors), on foot, and within inaccessible areas (i.e., private lands) afar using binoculars to the extent practical. The survey shall be conducted by a biologist familiar with the identification of avian species known to occur in the area. If nests are found, an avoidance buffer (which is dependent upon the species, the proposed work activity, and existing disturbances associated with land uses outside of the site) shall be determined and demarcated by the biologist with bright orange construction fencing, flagging, construction lathe, or other means to mark the boundary. All construction personnel shall be notified as to the existence of the buffer zone and to avoid entering the buffer zone during the nesting season. No ground- disturbing activities shall occur within this buffer until the avian biologist has confirmed that breeding/nesting is completed and the young have fledged the nest. Encroachment into the buffer shall occur only at the discretion of the qualified biologist. CULTURAL RESOURCES 8. A qualified principal investigator, defined as an archaeologist who meets the Secretary of the Interior’s Standards for professional archaeology (hereafter qualified archaeologist), shall be retained to carry out all mitigation measures related to archaeological resources. 9. Mitigation of archaeological resources within the project area shall follow the Consolidated Approach as outlined in the City of San Luis Obispo Archaeological Resource Preservation Program Guidelines. The Consolidated Approach shall include (1) the preparation of a Research Design and Mitigation Plan prepared by the qualified archaeologist and submitted for written approval to the City’s Community Development Director (Director), which shall include but not be limited to the research design, laboratory and field methods, public interpretation, and location of curation; (2) monitoring of demolition and clearing of pavement within the project area; (3) fieldwork after the removal of pavement consisting of a Phase I inventory, Phase 2 Testing and Evaluation, and Phase 3 Data Recovery aimed at locating archaeological remains, evaluating their significance and integrity, and mitigating impacts through data recovery excavation; (4) the completion of special studies, such as faunal analysis, if appropriate, and the curation of recovered artifacts; and (5) the completion of a technical report documenting the results of the consolidated approach prepared in accordance with current professional standards and submitted to the Director. 10. An archaeological monitor shall be present for all project-related ground-disturbing construction activities. The monitor(s) shall be onsite on a full-time basis during earthmoving activities, including grading, trenching, vegetation removal, or other excavation activities. Under consultation between the qualified archaeologist and the City, monitoring may be reduced or eliminated based on observed conditions. Introduction Phase 1B & Phase 2 Mitigation and Monitoring Plan 5 11. In the event that cultural resources are encountered during the implementation of Mitigation Measures 9 or 10, all work shall be halted in the vicinity of the discovery until a qualified archaeologist can assess the significance of the resource. If the resources are found to be significant, they must be avoided or mitigated pursuant to the qualified archaeologist’s direction and the testing plan outlined under Mitigation Measure 9. Mitigation may involve preservation in place or documentation and excavation of the resource. A report by the archaeologist evaluating the find and identifying mitigation actions taken shall be submitted to the City GEOLOGY AND SOILS 12. Once the final maximum loads of the project have been determined, a design-level geotechnical report shall be prepared that identifies the most appropriate geotechnical improvements to onsite soils, the foundation, and parking structure to minimize expansive soil hazards. Recommendations could include, but are not limited to the following:  Use imported non-expansive materials combined with pre-moistening of the soils to provide protection for slabs and flatwork  Provide a layer of non-expansive material 18 to 24 inches thick  Use post-tensioned slabs-on-grade  Implement shoring methods, such as shotcrete-faced soil nail walls, tangent drilled caissons, whaler-braced retaining walls, and steel I-beam and lagging walls  Use over-excavation and recompaction  Utilize a deep foundation system, such as caissons or rammed aggregate piers  A certified soils engineer shall be retained for monitoring during construction of the project. The certified soils engineer shall also provide any necessary soil testing during construction, to ensure compliance with the design-level geotechnical report, and to provide site-specific guidance as subsurface materials are encountered. HAZARDS AND HAZARDOUS MATERIALS 13. Prior to issuance of grading permits, additional soil samples testing for total petroleum hydrocarbons shall be performed. A work plan shall be completed to address the sampling protocols to be followed, as well as the number of samples to be taken and the chemical analysis required. Upon City of San Luis Obispo approval, the work plan shall be implemented and the results of the soil sampling shall be forwarded to the City of San Luis Obispo. The City shall review the data to determine if any additional investigation or remedial activities are deemed necessary. No work shall resume in that area until the lead local regulatory agency has provided written authorization that the area does not warrant any additional action. If concentrations of contaminants warrant remediation, contaminated materials shall be remediated either prior to or concurrent with construction. Remediation shall generally include a management plan which establishes design and implementation of remediation. Cleanup may include excavation, disposal, bio-remediation, or any other City of San Luis Obispo Cultural Arts District Parking Structure Project 6 treatment of conditions subject to regulatory action. All necessary reports, regulations and permits shall be followed to achieve cleanup of the site. The contaminated materials shall be remediated under the supervision of an environmental consultant licensed to oversee such remediation and under the direction of the lead oversight agency. The remediation program shall also be approved by the San Luis Obispo Fire Department. All proper waste handling and disposal procedures shall be followed. Upon completion of the remediation, the environmental consultant shall prepare a report summarizing the project, the remediation approach implemented, and the analytical results after completion of the remediation, including all waste disposal or treatment manifests. HISTORICAL RESOURCES 14. Impacts to historical resources shall be minimized through the preparation of archival historic building documentation packages for both 610 and 614 Monterey Street. Prior to issuance of demolition permits, the City of San Luis Obispo shall ensure that documentation of both properties is completed in the form of a Historic American Building Survey (HABS)-Like documentation that shall comply with the Secretary of the Interior’s Standards for Architectural and Engineering Documentation (NPS 1990). The documentation shall generally follow the HABS Level III requirements and include high- quality digital photographic recordation of the buildings and their overall setting, detailed historic narrative report, and compilation of historic research. The documentation shall be completed by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualification Standards for History and/or Architectural History (NPS 1983). Individual archival documentation packages shall be completed for both properties and offered as donated material to the San Luis Obispo Library and the History Center of San Luis Obispo County, where it would be available to local researchers. Completion of this mitigation measure shall be monitored and enforced by the lead agency. NOISE 15. Construction vehicles and haul trucks shall utilize roadways which avoid residential neighborhoods and sensitive receptors where possible. The applicant shall submit a proposed construction vehicle and hauling route for City review and approval prior to grading/building permit issuance. The approved construction vehicle and hauling route shall be used for all construction vehicles and hauling trips during the duration of construction. 16. Except for emergency repair of public service utilities or where an exception is issued by the Community Development Department, no operation of tools or equipment used in construction, drilling, repair, alteration, or demolition work shall occur daily between the hours of 7:00 PM and 7:00 AM, or anytime on Sundays, holidays, or after sunset, where that operation creates a noise disturbance that exceeds 75 dBA for single family residential, 80 dBA for multi-family residential, and 85 dBA for mixed residential/commercial land uses across a residential or commercial property line for a maximum of 10 days. For construction activities lasting more than 10 days, noise from construction equipment shall not exceed 60 dBA for single family residential, 65 dBA for multi-family residential, and 70 dBA for mixed residential/commercial land uses across a residential or commercial property line. Introduction Phase 1B & Phase 2 Mitigation and Monitoring Plan 7 17. For all construction activity at the project site, noise attenuation techniques shall be employed to reduce noise levels to extent feasible in accordance with the City of San Luis Obispo Municipal Code, Title 9, Chapter 9.12 (Noise Control). Such techniques shall include:  Sound blankets on noise-generating equipment Stationary construction equipment that generates noise levels above 60 dBA at the project boundaries shall be shielded with barriers that meet a sound transmission class (a rating of how well noise barriers attenuate sound) of 25.  All diesel equipment shall be operated with closed engine doors and shall be equipped with factory-recommended mufflers  For stationary equipment, the applicant shall designate equipment areas with appropriate acoustic shielding on building and grading plans. Equipment and shielding shall be installed prior to construction and remain in the designated location throughout construction activities  Electrical power shall be used to power air compressors and similar power tools  The movement of construction-related vehicles, with the exception of passenger vehicles, along roadways adjacent to sensitive receptors shall be limited to the hours between 7:00 AM and 7:00 PM, Monday through Saturday and no movement of heavy equipment shall occur on Sundays or official holidays (e.g., Thanksgiving, Labor Day)  Temporary sound barriers shall be constructed between construction sites and affected uses 18. The contractor shall inform residents and business operators at properties within 300 feet of the project site of proposed construction timelines and noise complaint procedures to minimize potential annoyance related to construction noise. Proof of mailing the notices shall be provided to the Community Development Department before the City issues a zoning clearance. Signs shall be in place before beginning of and throughout grading and construction activities. Noise-related complaints shall be directed to the City’s Community Development Department. 19. Prior to the issuance of grading permits, the City of San Luis Obispo shall review and coordinate the construction schedules of any other projects within 300 feet of the project to ensure that construction schedules do not overlap. PALEONTOLOGICAL RESOURCES 20. A qualified project paleontologist, defined as a paleontologist who meets the standards of the SVP (2010), shall be retained to carry out all mitigation measures related to paleontological resources. 21. Prior to the start of construction, the project paleontologist or his or her designee shall conduct training for construction personnel regarding the appearance of fossils and the procedures for notifying paleontological staff should fossils be discovered by construction staff. The WEAP shall be fulfilled at the time of a preconstruction meeting at which a qualified paleontologist shall attend. City of San Luis Obispo Cultural Arts District Parking Structure Project 8 22. Ground-disturbing construction activities (including grading, trenching, foundation work, and other excavations) in previously undisturbed sediments that exceed 10 feet in depth shall be monitored on a full-time basis during initial ground disturbance. Monitoring shall be conducted by a qualified paleontological monitor, who is defined as an individual who has experience with collection and salvage of paleontological resources and meets the minimum standards of the SVP (2010). The duration and timing of the monitoring will be determined by the project paleontologist and the location and extent of proposed ground disturbance. If the project paleontologist determines that full-time monitoring is no longer warranted, based on the specific geologic conditions at the surface or at depth, the project paleontologist may recommend that monitoring be reduced to periodic spot-checking or cease entirely. Monitoring is not necessary in artificial fill or for activities that do not reach 10 feet in depth. 23. In the event of a fossil discovery by the paleontological monitor or construction personnel, all work in the immediate vicinity of the find shall cease. The project paleontologist shall evaluate the find before restarting construction activity in the area. If it is determined that the fossil(s) is (are) scientifically significant, the project paleontologist shall complete the following conditions to mitigate impacts to significant fossil resources: a. Salvage of Fossils. The project paleontologist (or paleontological monitor) shall recover significant fossils following standard field procedures for collecting paleontological resources, as described by the SVP (2010). Typically, fossils can be safely salvaged quickly by a single paleontologist and not disrupt construction activity. In some cases, larger fossils (such as complete skeletons or large mammal fossils) require more extensive excavation and longer salvage periods. In this case the paleontologist shall have the authority to temporarily direct, divert or halt construction activity to ensure that the fossil(s) can be removed in a safe and timely manner. b. Preparation and Curation of Recovered Fossils. Once salvaged, significant fossils shall be identified to the lowest possible taxonomic level, prepared to a curation- ready condition, and curated in a scientific institution with a permanent paleontological collection (such as the University of California Museum of Paleontology), along with all pertinent field notes, photos, data, and maps. Fossils of undetermined significance at the time of collection may also warrant curation at the discretion of the project paleontologist. TRANSPORTATION 24. Prior to the issuance of each building permit, the construction contractor shall meet with the Public Works department to determine traffic management strategies to reduce, to the maximum extent feasible, traffic congestion and the effects of parking demand by construction workers during construction of this project. The construction contractor will develop a Construction Traffic Management Plan for review and approval by the Public Works department. The plan shall include at least the following items and requirements:  A set of comprehensive traffic control measures, including scheduling of major truck trips and deliveries to avoid peak traffic and pedestrian hours, detour signs if Introduction Phase 1B & Phase 2 Mitigation and Monitoring Plan 9 required, lane closure procedures, sidewalk closure procedures, signs, cones for drivers, and designated construction access routes.  Notification procedures for adjacent property owners and public safety personnel regarding when major deliveries, detours, and lane closures will occur.  Location of construction staging areas for materials, equipment, and vehicles (must be located on the project site).  Identification of haul routes for movement of construction vehicles that would minimize impacts on vehicular and pedestrian traffic, circulation and safety; and provision for monitoring surface streets used for haul routes so that any damage and debris attributable to the haul trucks can be identified and corrected by the project applicant.  Temporary construction fences to contain debris and material and to secure the site.  Provisions for removal of trash generated by project construction activity.  A process for responding to and tracking complaints pertaining to construction activity.  Provisions for monitoring surface streets used for truck routes so that any damage and debris attributable to the trucks can be identified and corrected. It is anticipated that this Construction Traffic Management Plan would be developed in the context of a larger Construction Management Plan, which would address other issues such as hours of construction onsite, limitations on noise and dust emissions, and other applicable items. 25. Subject to approval of the Public Works Director, the City shall incorporate improvements to the intersections of Dana Street/Nipomo Street and Monterey Street/Nipomo Street to enhance pedestrian safety and accessibility. The improvements shall be consistent with the City’s Circulation Element and Downtown Physical Concept Plan (2017) and shall balance the needs of each mode of use. At a minimum the project should consider:  High visibility crosswalk, or other intersection enhancements, with directional curb ramps across Nipomo Street from the northwest corner of Dana Street/Nipomo Street to the southwest corner of the parking structure.  High visibility crosswalk, or other intersection enhancements, with directional curb ramps from the southeast corner of Monterey Street/Nipomo Street across Nipomo Street.  Standard crosswalks, or other intersection enhancements, with directional curb ramps across Monterey Street and Dana Street where they intersect with Nipomo Street.  Reduce the curb radii on the southwest corner of Dana Street/Nipomo Street and the northeast corner of Monterey Street/Nipomo Street. City of San Luis Obispo Cultural Arts District Parking Structure Project 10 If the Community Development Director or hearing body determines that the above mitigation measures are ineffective or physically infeasible, they may add, delete, or modify the mitigation to meet the intent of the original measures. This MMP serves to comply, in part, with these mitigation measures by providing the standards and methods for monitoring to occur during project implementation. This document outlines the steps to be taken during unanticipated discoveries to mitigate potential significant impacts and provides methods for determining if and when monitoring may be reduced or eliminated during the course of project execution. Project Location and Description The project would remove of an existing 77-space surface parking lot and five existing residential structures, and construct a five-level parking structure, commercial space, and non-profit theater on five parcels, identified as Assessor’s Parcel Numbers (APNs) 002-412-001, 002-412-002, 002-412- 003, 002-412-004, 002-412-011, and 002-412-012. Main vehicular access to the structure would be from Palm Street, with secondary access from Nipomo Street. Vehicle access would not be provided from Monterey Street, but a direct pedestrian connection would be provided from the structure to Monterey Street. The parking structure’s maximum height would be 50 feet, excluding elevator towers. The maximum height of the commercial space would be 41 feet above existing grade. The theater would be a three-story structure with a gross floor area of roughly 23,841 square feet. The maximum height of the theater would be approximately 43 feet above existing grade. Section 2.5, Project Characteristics, of the 2018 Final EIR provides a detailed description of the project. The project site is depicted on the San Luis Obispo, California United States Geological Survey (USGS) 7.5-minute topographic map (Figure 1). The project area is bounded on the northwest by Palm Street, on the southwest by Nipomo Street, on the southeast by Monterey Street, and on the northeast by existing residential development. Environmental Resource Sensitivity AESTHETICS/VISUAL RESOURCES BACKGROUND The project site is located in the northwestern portion of the City’s designated Downtown Planning Area, adjacent to the Downtown Core. The majority of the project site and adjacent parcels to the east, south, and west are located within the City’s Downtown Historic District, which affects its visual context along Monterey and Nipomo Streets. Because of the project site’s location in a developed urban area, views of the project site are generally limited, with long-range views blocked by existing development or vegetation. The utility poles and wires that surround and cross over the site are another dominant visual feature of the project site. Elevations onsite range from 190 and 206 feet above mean sea level, and slopes are generally toward the northwest. AIR QUALITY BACKGROUND The South Coast Air Basin is in non-attainment for particulate matter (PM10), and the work area is located within 1,000 feet of sensitive receptors, including Mission College Preparatory Academy, existing residential units, and San Luis Obispo Children’s Museum). In accordance with the standards of the San Luis Obispo Air Pollution Control District CEQA Handbook standard mitigation measures Introduction Phase 1B & Phase 2 Mitigation and Monitoring Plan 11 Figure 1 Project Location Depicted on Topographic Background City of San Luis Obispo Cultural Arts District Parking Structure Project 12 are required during construction of the proposed utility improvements to reduce potential air quality impacts below applicable thresholds of significance. BIOLOGICAL BACKGROUND The project site is currently developed with a surface parking lot, one detached garage, and five residences, and is surrounded by urban land uses. The site does not provide suitable habitat for wildlife or sensitive plant or animal species, or any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or U.S. Fish and Wildlife Service. However, trees on the site may support nesting birds protected under the Migratory Bird Treaty Act. The federal Migratory Bird Treaty Act (16 United States Code Section 703-711) protects all migratory birds, their nests and eggs against take, possession, or destruction. The MBTA was enacted in 1918 and is enforced by the U.S. Fish and Wildlife Service. Abiding by the MBTA requires that active nests be avoided. CULTURAL BACKGROUND The current project is located in the City of San Luis Obispo in close proximity to the Mission San Luis Obispo de Tolosa. In 2018, the City conducted an environmental impact report to determine the potential environmental impacts for the Palm Nipomo Parking Structure Project (City of San Luis Obispo 2018). As part of this analysis the City determined that the current project site was within an archaeologically sensitive area; however, all portions of the project site are developed with hardscaping and likely disturbed due to previous development. As such, a pedestrian survey or archaeological testing was infeasible. Given the project is within areas determined to be sensitive for archaeological resources and in accordance with the City’s Archaeological Resource Preservation Program Guidelines, the project required archaeological monitoring during project-related ground disturbing activities to mitigate potential impacts to cultural resources (City of San Luis Obispo 2018; City of San Luis Obispo 2009). GEOLOGY/SOILS BACKGROUND The site is relatively flat with no significant slopes on or immediately adjacent to the site, and is not subject to geological hazards including landslides and slope instability. The soils consist of alluvial sediments overlying bedrock, with a potential for expansion. The soils are comprised of laterally discontinuous zones of sandy clay, clay, and clayey gravel extending to depths of 25 to 40 feet below the surface. HAZARDS AND HAZARDOUS MATERIALS BACKGROUND A hazardous materials assessment for the project site was prepared in April 2011 by Earth Systems Pacific. Based on the results of a government database records search, the project site is not included on a list of hazardous material sites compiled pursuant to Government Code Section 65962.5. Archived documents at the City of San Luis Obispo Fire Department indicate that the previous use of the site as a welding/automobile repair shop contained several areas of oil-stained soil, a dry well, and a hydraulic lift. It is unknown whether or not soil sampling was conducted at the time of removal of these features and there is a potential that these or other undocumented buried features would be encountered during excavation. Furthermore, soil samples taken in 2005 at three and four feet indicate the presence of total petroleum hydrocarbons in quantities that exceed City of San Luis Obispo Fire Department action levels. Introduction Phase 1B & Phase 2 Mitigation and Monitoring Plan 13 HISTORICAL RESOURCES BACKGROUND The project site is partially located within the locally designated City of San Luis Obispo Downtown Historic District (historic district). The historical resources analysis conducted as part of the 2018 Final EIR indicated the presence of two properties in the project site that contribute to the historic district, 610 and 614 Monterey Street; 614 Monterey Street has also been found individually eligible for historical designation. Due to their designation as contributors to the historic district, and in the case of 614 Monterey Street, its local eligibility, these properties are considered historical resources under CEQA and would be demolished by the project. The 2018 Final EIR determined that, due to the demolition of 610 and 614 Monterey Street, impacts to historical resources as a result of the project would be significant and unavoidable. However, implementation of Mitigation Measure CR-1 is required to reduce impacts to historical resources to the greatest extent possible. In addition to the direct impacts discussed above, the 2018 Final EIR analyzed the potential indirect impacts to historical resources associated with the project, in particular to the locally-designated Hays-Lattimer Adobe and Harmony Creamery. The 2018 Final EIR concluded that although the project would negatively affect the historic integrity of the Hays-Lattimer Adobe and Harmony Creamery, both would retain their ability to convey their significance and therefore, indirect impacts would therefore be less than significant. Therefore, no mitigation additional mitigation is required. NOISE BACKGROUND The primary noise sources in the project area are from U.S. 101, light vehicle traffic along Palm Street, Nipomo Street, and Monterey Street, and occasional noise from the Mission College Preparatory school athletic field. Noise-sensitive receptors closest to the project site include the following: single- and multi-family residential units adjacent to the northeast project boundary; the San Luis Obispo Children’s Museum located across Monterey Street, approximately 50 feet from the southeast project boundary; the Reis Family Mortuary across Nipomo Street, approximately 50 feet from the western project boundary; residential suites on the second story of the mixed-use development on the south corner of the intersection of Dana Street and Nipomo Street, approximately 60 feet from the southern project boundary; single-family residences located across Nipomo Street, approximately 90 feet from the western project boundary; and the Mission College Preparatory school athletic field across Palm Street, approximately 75 feet from the northwest project boundary. PALEONTOLOGICAL BACKGROUND The project site and surrounding region was mapped at a scale of 1:24,000 by Dibblee and Minch (2004), who identified a single geologic unit, Quaternary alluvium, underlying the project site. A geotechnical report for the project found alluvium at the surface or below the artificial fill, reaching a depth of 25 to 44 feet (Earth Systems Pacific 2011). Early Holocene and Pleistocene alluvial sediments have produced scientifically significant fossils throughout California, including San Luis Obispo County, yielding taxa such as mammoth (Mammuthus), mastodon (Mammut), horse (Equus), bison (Bison), camel (Camelops), ground sloth (Paramylodon), and rodent (Sciuridae) (Jefferson et al. 1992; Jefferson 2010; Paleobiology Database 2022; University of California Museum of Paleontology 2022). City of San Luis Obispo Cultural Arts District Parking Structure Project 14 TRANSPORTATION BACKGROUND Regional access to the project site is provided by U.S. 101, located west and north of the study area, and Highway 1, which coincides with and is designated Santa Rosa Street (north of U.S. Highway 101) near the project site. All of the study area roadways are classified as Local Commercial streets in the City’s General Plan Circulation Element. Plan Check Requirements Phase 1B & Phase 2 Mitigation and Monitoring Plan 15 2 Plan Check Requirements The following outlines the mitigation requirements that shall be reflected on final plans and/or project specifications. 1.

Prior to issuance of grading permits the Public Works Director or other City compliance monitor shall review and coordinate the construction schedules of any other projects within 300 feet of the project to ensure that construction schedules do not overlap. 11. Prior to issuance of zoning clearance the Community Development Director or other City compliance monitor shall review and approve proof that the contractor has mailed notices to residents and business operators at properties within 300 feet of the project site of proposed construction timelines and noise complaint procedures to minimize potential annoyance related to construction noise. 12. Prior to issuance of each building permit the Public Works Director or other City compliance monitor shall review and approve a Construction Traffic Management Plan that identifies traffic management strategies to reduce, to the maximum extent feasible, traffic congestion and the effects of parking demand by construction workers during construction of this project. (This measure may be developed in the context of a larger Construction Management Plan.) The Construction Traffic Management Plan shall include: City of San Luis Obispo Cultural Arts District Parking Structure Project 20  A set of comprehensive traffic control measures, including scheduling of major truck trips and deliveries to avoid peak traffic and pedestrian hours, detour signs if required, lane closure procedures, sidewalk closure procedures, signs, cones for drivers, and designated construction access routes.  Notification procedures for adjacent property owners and public safety personnel regarding when major deliveries, detours, and lane closures will occur.  Location of construction staging areas for materials, equipment, and vehicles (must be located on the project site).  Identification of haul routes for movement of construction vehicles that would minimize impacts on vehicular and pedestrian traffic, circulation and safety; and provision for monitoring surface streets used for haul routes so that any damage and debris attributable to the haul trucks can be identified and corrected by the project applicant.  Temporary construction fences to contain debris and material and to secure the site.  Provisions for removal of trash generated by project construction activity.  A process for responding to and tracking complaints pertaining to construction activity.  Provisions for monitoring surface streets used for truck routes so that any damage and debris attributable to the trucks can be identified and corrected. 13.

Additional plans requiring review and approval by the Community Development Director prior to Encroachment Permit issuance include an archaeological monitoring plan consistent with the requirements of the City’s Archaeological Resource Preservation Guidelines, which is incorporated in this MMP as Section 3, Monitoring Requirements. Monitoring Requirements Phase 1B & Phase 2 Mitigation and Monitoring Plan 21 3 Monitoring Requirements AIR QUALITY MITIGATION MONITORING REQUIREMENTS Periodically during construction (minimum once per month) the City compliance monitor shell field verify compliance with the Fugitive Dust Control Requirements, Standard Control Measures for Construction Equipment, BACT for Construction Equipment, and Architectural Coating mitigation requirements reflected in final plans and specifications. Periodic field monitoring shall continue until the City compliance monitor has determined that the specific mitigation requirements have been fully met and/or construction is complete. BIOLOGICAL RESOURCES/NESTING BIRD MITIGATION MONITORING REQUIREMENTS If construction activities related to the project, including, but not limited to, vegetation removal, ground disturbance, and construction and demolition, must begin between February through August, prior to initiation of construction activities the City compliance monitor shall ensure a qualified biologist completes a pre-construction nesting bird survey no more than 3 days prior to initiation of ground disturbance and vegetation removal activities. The nesting bird pre-construction survey shall be conducted within the Project Boundary, including a 300-foot buffer (500-foot for raptors), on foot, and within inaccessible areas (i.e., private lands) afar using binoculars to the extent practical. If nests are found, an avoidance buffer (which is dependent upon the species, the proposed work activity, and existing disturbances associated with land uses outside of the site) shall be determined and demarcated with bright orange construction fencing, flagging, construction lathe, or other means to mark the boundary by the qualified biologist under the supervision of the City compliance monitor. The City compliance monitor shall notify all construction personnel as to the existence of the buffer zone and to avoid entering the buffer zone during the nesting season. No ground- disturbing activities shall occur within this buffer until the qualified biologist has confirmed that breeding/nesting is completed and the young have fledged the nest. Encroachment into the buffer shall occur only at the discretion of the qualified biologist. CULTURAL/ARCHAEOLOGICAL RESOURCES MITIGATION MONITORING REQUIREMENTS In compliance with the 2018 Final EIR archaeological monitoring is required for all project-related ground disturbance . All archaeological monitoring efforts shall be conducted under the direction of an archaeologist meeting the Secretary of the Interior’s Professional Qualifications Standards for archaeology (National Park Service [NPS] 1983; hereafter, Qualified Archaeologist). Archaeological monitor(s) shall be onsite during all project-related earthmoving activities. Earthmoving activities include, but are not limited to, vegetation removal, grading, excavation, trenching, and all other excavation activities. During monitoring, the monitors shall examine the work areas for the presence of prehistoric artifacts (e.g., chipped stone tools and production debris, stone milling tools, ceramics), historic-period debris (e.g., metal, glass, ceramics), and/or soil discoloration that might indicate the presence of a cultural midden. Each monitor shall maintain a daily log documenting ground disturbing activity, work locations, description and provenience of any archaeological discoveries (if any), and any necessary action items for monitoring City of San Luis Obispo Cultural Arts District Parking Structure Project 22 In the event of a find, the archaeological monitors retain the authority to temporarily halt and redirect work until the resource(s) have been evaluated and the area cleared for construction activities to recommence. If the archaeological resource is prehistoric in nature, a local Native American group will be contacted to and given the opportunity consult with the City regarding the find and provide recommendation. A Native American monitor will be retained for the remainder of earth disturbing activities should a prehistoric resource be found during construction. Protocols in the case of a find are discussed in greater detail in Section 4 below. Monitoring shall continue until the Qualified Archaeologist, in coordination with the City (and Native American monitor if present), has determined that the monitoring may be reduced or eliminated. Reasons for reducing or eliminating monitoring may include but not be limited to observed field conditions such as: soils that appear to lack any organic material (sterile), soils that are determined to be not native to the area, areas found to be heavily disturbed by modern activities, or the encounter of undisturbed hardpan/bedrock type soil conditions or depth of excavation (i.e., exceeds a depth where cultural resources may reasonably be expected). When/if culturally sterile soils are encountered during monitoring, the Qualified Archaeologist will provide a written recommendation (via email or other method acceptable to the City) to reduce or eliminate the monitoring effort. Should the City accept the recommendation, the reduction or elimination will commence immediately upon approval. NOISE MITIGATION MONITORING REQUIREMENTS Prior to initiation of grading and construction activities the City compliance monitor shall field verify signs are in place directing noise-related complaints to the City’s Community Development Department. Periodically during construction (minimum once per week) the City compliance monitor shall field verify compliance with signage requirements, in addition to the Construction Work Hours and Construction Equipment Noise Management Techniques mitigation requirements reflected in final plans and specifications. Periodic field monitoring shall continue until the City compliance monitor has determined that the specific mitigation requirements have been fully met and/or construction is complete. PALEONTOLOGICAL RESOURCES MITIGATION MONITORING REQUIREMENTS In compliance with the 2018 Final EIR, paleontological monitoring is required during initial ground disturbance of sediments deeper than 10 feet below surface, with the project paleontologist (defined as an individual meeting the standards of a Qualified Professional Paleontologist per SVP [2010]) modifying the monitoring schedule as appropriate (City of San Luis Obispo 2007). Excavations that are less than 10 feet below the surface or are in previously disturbed sediments, do not require monitoring. Monitoring will be conducted by a paleontological monitor (defined as an individual meeting the standards of a Qualified Paleontological Monitor per the standards of the SVP [2010]). Monitoring will consist of the visual inspection of excavated or graded areas, trench and pit sidewalls, and spoils piles. Paleontological monitoring is documented in daily electronic monitoring logs, which at a minimum, include a description of areas monitored, monitor name(s), a summary of monitoring activities, and a description of the disturbed geologic units within a stratigraphic context. In paleontologically sensitive areas, or in adjacent areas that can provide context for the geology and paleontology, Monitoring Requirements Phase 1B & Phase 2 Mitigation and Monitoring Plan 23 outcrops and cut exposures will be examined and observed geologic features will be recorded when/if available. The paleontological monitor will be equipped with hand tools and supplies (e.g., geological hammer, shovel, pick, chisels, whisk broom, buckets, specimen bags, field notebook, forms, pens, markers, and glue) to allow for the rapid salvage of fossil remains. At all times, the paleontological monitor will wear the appropriate personal protective equipment in compliance with the on-site contractor PPE work rules, including a hard hat, heavy footwear, sleeved shirt, long pants, safety glasses, and a high-visibility safety vest. In the event of a find, the paleontological monitor retains the authority to temporarily halt and redirect work until the resource(s) have been evaluated and the area cleared for construction activities to recommence. Monitoring shall continue until the project paleontologist, in coordination with the City, has determined that the monitoring may be reduced or eliminated. Reasons for reducing or eliminating monitoring may include but not be limited to observed field conditions such as: soils that appear to lack any potential to encounter paleontological resources (sterile), soils that are determined to be not native to the area, or areas found to be heavily disturbed by modern activities. When/if paleontologically sterile soils are encountered during monitoring, the project paleontologist will provide a written recommendation (via email or other method acceptable to the City) to reduce or eliminate the monitoring effort. Should the City accept the recommendation, the reduction or elimination will commence immediately upon approval. If the construction schedule changes or excavations begin in a new area, the project paleontologist may reinstate paleontological monitoring. City of San Luis Obispo Cultural Arts District Parking Structure Project 24 4 Archaeological Testing Requirements In compliance with Mitigation Measure 9, “fieldwork after the removal of pavement consisting of a Phase I inventory, Phase II Testing and Evaluation, and Phase III Data Recovery aimed at locating archaeological remains, evaluating their significance and integrity, and mitigating impacts through data recovery excavation; the completion of special studies, such as faunal analysis, if appropriate” is required. As part of mitigation, an extended Phase I of CA-SLO-2431H shall be conducted. If CA-SLO-2431H contains subsurface cultural materials, the resource shall be evaluated for significance and eligibility for listing in the CRHR through the implementation of a Phase II evaluation program. Phase II evaluations shall include any necessary archival research to identify significant historical associations as well as mapping of surface artifacts, collection of functionally or temporally diagnostic tools and debris, and excavation of a sample of the cultural deposit to characterize the nature of the sites, define the artifact and feature contents, determine horizontal boundaries and depth below surface, and retrieve representative samples of artifacts and other remains. If the resource is found eligible for listing on the NRHP, CRHR, or local register, a Phase III data recovery program shall be conducted to mitigate the impacts to the resource if avoidance remains infeasible. A data recovery program shall include the development of a site-specific research design, testing program, laboratory analysis, and reporting with the intention of extracting data from the resource to the point of redundancy. Cultural materials collected from the sites shall be processed and analyzed in the laboratory according to standard archaeological procedures. The age of archaeological resources shall be determined using radiocarbon dating or other appropriate procedures; metal, ceramic, faunal remains, and other cultural materials shall be identified and analyzed according to current professional standards. The significance of the resource shall be evaluated according to the criteria of the CRHR. The results of the investigations shall be presented in a technical report following the standards of the California Office of Historic Preservation publication “Archaeological Resource Management Reports: Recommended Content and Format (1990 or latest edition).” Any necessary archaeological data recovery excavation shall be carried out by a Registered Professional Archaeologist according to a research design reviewed and approved by the City, as the lead agency, and prepared in advance of fieldwork and using appropriate archaeological field and laboratory methods consistent with the California Office of Historic Preservation Planning Bulletin 5 (1991), Guidelines for Archaeological Research Design, or the latest edition thereof. Upon completion of the work, all artifacts, other cultural remains, records, photographs, and other documentation shall be curated an appropriate curation facility to be determined on a case-by-case basis in consultation with the City and interested parties (e.g., historical organizations). Resource Discovery Plan Phase 1B & Phase 2 Mitigation and Monitoring Plan 25 5 Resource Discovery Plan The following outlines the procedures to be followed in the inadvertent discovery of cultural resources, including human remains. Discovery of Archaeological Resources The procedure for dealing appropriately with unanticipated resources encountered during construction will include, but not be limited to, the following: For the discovery of previously unknown archaeological resources: The archaeological monitor will divert construction activity in the immediate vicinity of the find by signaling to construction staff and notifying the designated construction foreman. The monitor will report the discovery to Rincon’s qualified archaeologist and the City’s construction inspector. The “immediate vicinity” will vary depending upon specific circumstances. If the archaeological resource is prehistoric in nature, a local Native American group will consult about the find, and a Native American monitor will be retained for the remainder of earth disturbing activities. Upon completion of the above notification, the archaeological monitor will determine the nature and extent of the cultural remains and make a preliminary assessment of their integrity and potential importance. If the archaeological monitor determines that the discovery is not cultural, or is an isolated artifact, the monitor will immediately notify the qualified archaeologist and construction manager that activities may resume as soon as the archaeological item(s) has been properly photographed and recorded. If potentially significant cultural features, artifact concentrations, or intact deposits are discovered, the archaeological monitor will divert construction activity in the immediate vicinity and report the discovery to the qualified archaeologist and the City’s construction inspector so that appropriate notifications to the City can be issued. A temporary Construction Exclusion Zone (CEZ), consisting of lath and flagging tape, will be erected around the discovery. The size of the CEZ may be reduced or enlarged as the significance and extent of the find is determined and treatment measures are implemented. For the purposes of the current effort, a minimum 100-foot radius shall be established for any remains that are suspected of being human (see Section 4.2 for further direction related to the discovery of human remains). Isolated artifacts shall be marked by an orange cone or flagging with no additional radius. In the case of the discovery of an intact archaeological site, a radius of 100 feet may be established so that the resource may be evaluated. This radius may be reduced or expanded based on the nature of the resource and the area required for archaeologists to work safely. The CEZ will not be removed until the potentially significant cultural resource has been evaluated to assess whether it is classified as a “historical resource,” pursuant to the California Environmental Quality Act (CCR, § 15064.5[a]). To minimize construction delays, if a potentially significant cultural resource is discovered during monitoring, Rincon will immediately contact the City to formulate a plan for further treatment. Cultural resources identified within the site shall be recorded according to current archaeological standards. This shall include the preparation of California Department of Parks and Recreation (DPR) Series 523 forms. Pertinent information concerning the resource(s) shall be recorded, including the site type, components, size, and provenience. Upon completion, the Series 523 forms shall be City of San Luis Obispo Cultural Arts District Parking Structure Project 26 submitted to the California Historical Resources Information System’s Central Coast Information Center, located at the Santa Barbra Museum of Natural History for primary number and trinomial designation. Final copies of the Series 523 forms shall be included in the final monitoring report. In addition to the Series 523 forms, a final compliance report shall be prepared as presented in Section 5.1 below. Discovery of Human Remains There is a possibility that the project’s construction-related activities may encounter human burials or cremations. Therefore, if the project’s construction-related activities find potential human bone, ground-disturbing activities in the area of the discovery shall immediately be halted or redirected while a temporary CEZ surrounding the site of discovery is established to allow for further examination and treatment of the find. The qualified archaeologist shall also immediately notify the City and the San Luis Obispo County Coroner’s Office by telephone, pursuant to Health and Safety Code 7050.5. By law, the Coroner will determine within 48 hours of being notified if the remains are subject to his or her authority. If the human remains are determined to be prehistoric, the coroner will notify the Native American Heritage Commission, which will determine and notify a most likely descendant (MLD). The MLD shall complete the inspection of the site within 48 hours of being granted access and provide recommendations for the treatment of any human remains and artifacts associated with Native American burials. Discovery of Paleontological Resources In the event of a paleontological resource discovery, all work in the immediate vicinity of the discovery will be halted and a 50-foot buffer will be delineated around the discovery, to create a construction equipment exclusion zone to allow the paleontological monitor a safe zone to work within. The project paleontologist will determine if the discovery has fossil(s) that have the potential to be significant, and if they do, they shall recover the fossils following standard field procedures. Most fossils can be safely salvaged quickly by a single paleontological monitor and not disrupt construction activity. In some cases, larger fossils (such as complete skeletons or large mammal fossils) require more extensive excavation and longer salvage periods. During recovery of potentially significant fossils, the paleontological monitor will document all identification and recovery efforts, including assigning a unique field number to each fossil specimen, fossil locality, or sediment sample, and record the field number and associated specimen/sample data (identification by taxon and element, sample size, etc.), corresponding geologic data (particularly lithology, stratigraphic unit, stratigraphic level within the unit, inferred age, etc.), and geographic site data (UTM coordinate location, elevation, etc.) in their field notes. Reporting of Monitoring Results and Curation Finds Phase 1B & Phase 2 Mitigation and Monitoring Plan 27 6 Reporting of Monitoring Results and Curation Finds Reporting of Archaeological Monitoring Results At the conclusion of the construction activities requiring archeological monitoring, an archaeological monitoring report shall be prepared under the direction of the qualified archaeologist. The monitoring report will outline the methodology of archaeological mitigation at the project site, describe the construction activity and duration, and present the results of the monitoring. The level of effort to complete a monitoring report is dependent on the number of resources recovered during monitoring activities. Should the monitoring effort be negative for the identification of cultural resources, a negative letter report shall be prepared. The letter report shall include, at a minimum, the dates of monitoring, activities conducted, personnel, and field logs. If archaeological materials are recovered, a comprehensive technical report will also be required to describe and interpret findings and data. The technical report shall be prepared in accordance with the Archaeological Resources Management Reports (ARMR): Recommended Contents and Format. If required, the ARMR-format report shall include a complete description of resources identified during monitoring, treatment of those resources, National Register of Historic Places (NRHP) eligibility recommendations, site records, and site maps. The final version of the monitoring report shall be submitted to the City and the Central Coast Information Center of the California Historical Resources Information Center. Curation of Archaeological Finds Recovered archaeological finds not associated with burials will be temporarily stored by Rincon until either an appropriate on-site reburial location or repository is agreed upon by the City, other interested Native American groups, and/or MLD. If necessary, curation preparation will include creating acid-free labels and tags, placing artifacts in archival quality bags and boxes, and submitting a hard copy of the report on acid-free paper with and the artifacts to the selected curation facility. Permanent treatment of human remains and associated funerary items shall be determined by the MLD in coordination with the City. Reporting of Paleontological Monitoring Results At the conclusion of construction activities requiring paleontological monitoring, a paleontological monitoring report shall be prepared under the direction of the project paleontologist. The monitoring report will present the paleontological mitigation and the methods by which it was satisfied within the project site. The level of effort to complete a monitoring report is dependent on the nature of the resources recovered during construction. Should the monitoring effort be negative for the identification of paleontological resources, a negative letter report shall be prepared. The letter report shall include, at a minimum, the dates of monitoring, activities conducted, personnel, and field logs. If paleontological resources are recovered, a comprehensive technical report will be City of San Luis Obispo Cultural Arts District Parking Structure Project 28 required to describe and interpret findings and data consistent with the requirements of the SVP (2010). Curation of Paleontological Resources All paleontological resources and data recovered from the project site shall be curated together at the Santa Barbara Museum of Natural History. All collected fossil resources are the property of the City and shall be provided to the Santa Barbara Museum of Natural History along with a deed of gift. Curation would require placement of fossils into archival specimen trays with labels containing relevant curatorial information. A copy of the Project’s curation agreement with the Santa Barbara Museum of Natural History is attached as Appendix 1.

The SBMNH actively curates and provides a safe repository for specimens using contemporary methods for preserving fossils, including maintaining microenvironments in environmentally-controlled collections ranges, maintaining a digital database that archives all contextual data associated with each specimen, and maintaining a fossil preparation laboratory to repair and conserve fossils. The SBMNH is willing to consider accepting the collection(s) if all of the following conditions are met:  All collections must be accompanied by deed-of-gift and transfer of ownership documentation giving free and clear title of the collection to SBMNH.  Material from government lands must be accompanied by a copy of the official collecting permit.  All localities must be described in detail, including a precise description of the geographic location with GPS coordinates (stating datum used), lithology, stratigraphy (including unit designation), relative/absolute ages, and depositional environment if known.  All localities must be plotted on standard USGS topographic or geologic maps and located within Santa Barbara, Ventura, or San Luis Obispo counties. In certain situations, collections derived from localities outside of those counties may be accepted on a case-by-case basis with prior approval from the Earth Science Curator.  All collections must include a specimen catalog that clearly correlates physical specimens to locality and preparation data.  All collections must include printed and digital copies of final reports, any field notes, environmental impact reports, maps, charts, photographs, and other documentation as appropriate. All records must include site number and accession number.  All specimens must be fully stabilized and prepared. Specimens must be accompanied by notes on preparation methods, including consolidants and tools used.  All specimens must be identified to the lowest taxonomic level possible.  Larger specimens (e.g., mammoth limb bones) must be fully supported in archival cradles (field jackets are not acceptable).  If the collection is relatively large, it must be accompanied by the same specimen cabinets, drawers, and archival-quality trays used by SBMNH. Confer with the Earth Science Curator for estimated costs. Our estimated costs for curation, cataloging, and labeling of specimens are $20/locality and $12/specimen. For invertebrates and microfauna that are from the same locality and taxon, cataloging as lots is acceptable and counted as a single specimen. The estimated costs of permanent storage, including maintenance, is $300 per cubic foot of fully prepared fossils. Sincerely, Jonathan M. Hoffman, Ph.D. Dibblee Curator of Earth Science Vertebrate Zoology Department (805) 682-4711 ext. 157 jhoffman@sbnature2.org 25 From:Marquart, Ben Sent:Monday, April 17, 2023 10:04 AM To:Brush, Matthew Cc:rstefanek@kitchell.com; Guzman, Manuel; Banker-Hix, Wyatt Subject:RE: GAS : 633A & B Palm Street and 610 & 614 Monterey Street Gas Disconnect ORDER: 540000555914 SCHEDULED: 4/28/23 Thank You From: Brush, Matthew <MBrush@socalgas.com> Sent: Monday, April 17, 2023 7:41 AM To: Marquart, Ben <bmarquar@slocity.org> Cc: rstefanek@kitchell.com; Guzman, Manuel <mguzman@slocity.org>; Banker-Hix, Wyatt <wbanker@slocity.org> Subject: GAS : 633A & B Palm Street and 610 & 614 Monterey Street Gas Disconnect ORDER: 540000555914 SCHEDULED: 4/28/23 Good Morning Ben, Socalgas contractor ARB is scheduled to start abandoning gas services on Friday 4/28/23.

To recap, I am newly assigned to the City of San Luis Obispo, Cultural Arts District Parking Structure project and was looking to get up to speed with Charter’s involvement in the project or if any requests for service disconnection have been made yet? I have four sites (610 Monterey St, 614 Monterey St, 633A Palm St, and 633B Palm St) that are scheduled for demolition, and I need to verify that there are no con nections to the residences or property and if so, have them removed. Here ae my questions. 1. Have any requests been made to Charter to remove services at the above addresses? 2. Is there a process to get on Charters schedule? 3. What timeframe are we looking at? 4. Is there anything else you might need from me (the City) to proceed? 54 Thank you for your time, Ben Marquart Engineering Inspector IV Public Works 919 Palm Street, San Luis Obispo, CA 93401-7314 E bmarquart@slocity.org C 805.540.9192 slocity.org Stay connected with the City by signing up for e-notifications 55 From:Ryan Stefanek <rstefanek@kitchell.com> Sent:Wednesday, March 22, 2023 3:51 PM To:Marquart, Ben; Gauna, Samuel Subject:FW: City of SLO Cultural District Parking Structure Phase 1B: Approver Ryan Stefanek Updated their Response for Submittal (#017419-1.0: ) Attachments:01 7419 Combined Waste Management Plan CADPS.pdf Follow Up Flag:Follow up Flag Status:Flagged This message is from an External Source.

American initially functioned from office as a brokerage for distribution of oils, lubricants, and various solvents. In early 1952, the company rented a warehouse on Hindry Street in Inglewood to store products before bein delivered to customers. In June 1953, the company moved to the current location at 425 Isis Avenue. In mid-1961, American purchased a 75-foot-wide strip along the northern portion of original parcel and built additional office and warehouse space. American expanded in 1967 when it began leasing an additional 41-foot-wide strip of land from Edward and Veda Bennet was located directly north of the Site. Veda Bennett remained the owner of this northernmost parcel (231 feet long by 41 feet wide) until October 1989, when it was purchased by Rho-Ch Corporation. Waste solvent recycling began at the Facility in approximately 1964. Richard O’Meara formed F&C Waste Chemical, which was essentially a “paper company”. In 1970, Bonnie O’Meara created ABCO Industries and assumed ownership of the solvent recovery systems from American. F&C Waste Chemical discontinued the distribution of oils and lubricants in 1972. In February 1974, Bonnie O’Meara purchased both F&C and Richard O’Meara’s stock in American. In July 1974, ABCO Industries merged with American, and in August 1974, the merged company was renamed Rho-Chem Corporation. In late 1989, shortly after Rho-Chem acquired the northern 41-foot-wide parcel from Veda Bennett, Browning Ferris Industries, Inc. purchased Rho-Chem. In 1990, Southdown, Inc. (now CEMEX) acquired Rho-Chem. In May 1995, Philip Services Corporation acquired Rho-Chem from Southdown and leased the non-RCRA portion of the facility located to the west of the Facility at 8722 Aviation Boulevard. Southdown Inc. continued to own the land and continued to implement the Corrective Action (subsurface cleanup/remediation) under DTSC oversigh through a Corrective Action Consent Agreement signed in 2002. The name of the (aboveground) permitted Facility remains Rho-Chem LLC. Ownership of Rho-Chem LLC was transferre Stericycle Inc. in 2016 and later in April 2020 to Harsco/Clean Earth. Rho-Chem is a hazardous waste management facility located at 425 Isis Avenue, Inglewood, Los Angeles County, California 90301 (Facility). The Facility is located west of Isis Avenue, of Manchester Boulevard, east of Aviation Boulevard, and north of Hillcrest Boulevard. The Facility is situated on approximately 1.1 acres of land in an urban, industrial and commercial a one mile north-northeast of Los Angeles International Airport and four miles east of the Santa Monica Bay. The Los Angeles County assessor’s parcel numbers that describe the Facility location are 4126-003-020 and 4216-003-017. The main structure at the Facility is a one-story, approximately 3,300-square-foot building that houses the administrative offices, a laboratory, drum storage areas, boiler and electrical ro an employee locker room, and restrooms. A driveway encircling the main office building to the north, west, and south is used for incoming and outgoing traffic. Other features outside the office building include an employee and visitor parking area, aboveground storage tanks (ASTs), a drum storage area, and associated support facilities. The Facility is enclosed by a 6- to foot-high chain-link security fence topped with barbed wire and by the exterior walls of structures located on adjacent properties. The current operations and services include laboratory packing/de-packing liquid fuel blending, solvent recycling (fractionation column, batch distillation, and thin film evaporation), and s distribution. The facility also provides hazardous waste transfer, storage, and consolidation services. Residues from the solvent recycling operation and flammable hazardous wastes are incorporated into the fuel blending process. These materials are later shipped to other facilities as fuels for burning or incineration. In addition, Rho-Chem receives corrosives and wastew material for consolidation and off-site treatment. The Permittee is also a registered hazardous waste transporter. Rho-Chem operates a 0.8-acre parcel leased as a 10-day hazardous wa transfer facility at 8722 Aviation Boulevard. The transfer facility is not within the boundary of the Facility and is not part of this permit. Rho-Chem operations are pursuant to a Hazardous Waste Facility Permit, issued by the Department of Health Services, on September 28, 1990. On March 29, 1995, Rho-Chem submit permit renewal application and DTSC determined that they could continue to operate under existing permit conditions until a new permit was issued. The current Permit was issued on J 2008 with an effective date of August 28, 2008. The current permit authorizes nine hazardous waste management units. Releases from the facility continue to exist in the vadose zone and have migrated to ground water which is at 100 to 110 feet below ground surface (bgs). Many of the contaminants iden during the sampling are mobile in gas-phase, primarily aromatic and halogenated volatile organic compounds such as benzene, ethyl benzene, perchloroethene (PCE), and trichloroethy (TCE). Other constituents of concern include metals such as lead, cadmium, arsenic, mercury, barium, selenium and silver; semi-volatile organic compounds; and a variety of pesticides DTSC also provides oversight for the current Corrective Action Program for the Site. PERMITTING REGULATORY DESCRIPTION/HISTORY On November 14, 1980, the owner/operator filed a Part A Permit Application and was granted an Interim Status Document (ISD) by the California Department of Health Services (DHS), predecessor to DTSC, on April 6, 1981. On December 30, 1983, DHS issued a hazardous waste facility permit, permit number CAD 008364432, to Rho-Chem. On September 28, 1990, DTSC issued a RCRA-equivalent Hazardous Waste Facility Permit, number 90-3-TS-002, to Rho-Chem. In 1992, Southdown Environmental Systems, Inc. acquired the Rho-Chem Facility. In 1995, Phillip Services acquired the Rho-Chem Facility. On September 27, 1995 the Hazardous Waste Facility Permit (that was issued in 1990) expired. On March 29, 1995, Rho-Chem submitted a permit renewal application.. On March 12, 2001, the company name for Southdown Environmental Systems was changed to CEMEX, Inc. CEMEX, Inc. has assumed responsibility for the corrective action program Rho-Chem Corporation and CEMEX, Inc. have signed, as responsible parties, a corrective action consent agreement with DTSC on November 22, 2002. On January 7, 2008, Rho-Chem notified DTSC that its name would be changed from Rho-Chem Corporation to Rho-Chem, LLC, effective April 2008. After a series of revisions to the 19 Permit Renewal Applications in 1997, 2004 and 2008, DTSC issued the current Permit on July 25, 2008 with an effective date of August 28, 2008. On August 10, 2011 PSC submitted a Class 2 Permit Modification request to add use of Totes type of containers and capability to store propane cylinders at the Facility to DTSC and the permit modification was approved by DTSC on March 8, 2012 and became effective on March 8, 2012. HEALTH RISK ASSESMENT Rho-Chem submitted a draft Human Health Risk Assessment (HHRA) Report to DTSC on November 30, 2016 in support of their corrective measures study addressing the sub-surface contamination. DTSC reviewed the HHRA and provided comments on May 8, 2017. Response from Rho-Chem is awaited.

A reminder letter for permit renewal was issued on August 27, 2016 reminding the facility operator of the requirement to subm application for permit renewal at least 180 days prior to the expiration date and recommending that the permit application be submitted 18 months prior to the current permit expiration da pre-application meeting for the permit renewal was held on April 20, 2017. On February 22, 2018 Stericycle, Inc. submitted an application for the permit renewal Permittee to DTSC. On March 21, 2018 DTSC notified the Permittee that their permit renewal application was administratively incomplete and requested another meeting on April 10, 2018 to further explain changes in the regulatory process for processing permit renewals (that became effective from April 1, 2016). These changes include the need for a signed Cost Reimbursement Agreeme with a Cost Estimate, and an advance payment of 25% of the total estimated cost, for DTSC to begin technical review of the permit renewal application. On June 5, 2018, Stericycle Inc. submitted a revised Permit Application. On June 15, 2018 DTSC informed Stericycle Inc. that their permit renewal application is administratively complete and commenced technical revi the application. When an administratively complete renewal application is received prior to the expiration date, California regulations allow continued operation of permitted facilities unde terms of the expired permit until DTSC issues a decision to renew (or deny) the permit. DTSC completed the Technical Review and issued a First Notice of Deficiency (NOD #1) on May 2019. Rho-Chem submitted a Response to NOD #1 and a revised permit application on August 30, 2019. On April 6, 2020, Stericycle Inc. submitted supplemental information in response to the NOD#1, consisting of partial closure certification reports for some equipment at the Inglewood Fa including Fractionation Column, Thin Film Evaporator, Tank 30 (part of the Thin Film Evaporator system), Tank 31 (part of the Thin Film Evaporator system), Tank 67 (part of the Fraction Column system) and Tank 68 (part of the Fractionation Column system). OWNERSHIP CHANGE: On May 13, 2020 DTSC received a notification that the ownership of the Rho-Chem LLC Inglewood Facility has been transferred from Stericycle Inc. to Harsco/Clean Earth Inc.

Facilities, Design, Construction and Operations Facility Description The Kettleman Hills Facility is located about four (4) miles southwest of Kettleman City in a rural area of Kings County, CA, surrounded by lands used for grazing of animals and for oil and gas production. The closest facility is located approximately 2.5 miles to the north-northeast. The facility is situated on a 1600-acre property with 555 acres currently available and permitted for waste management activities. KHF provides waste treatment, storage, and disposal operations for non-hazardous waste, hazardous waste and municipal solid waste. NUMBER OF EMPLOYEES KHF currently employs 35 full-time employees and 2 – 4 contract labor personnel. Site History Including Landfill Cells The Kettleman Hills facility has been used for waste disposal activities since the late 1960s. Land disposal of municipal sewage took place in the late 1960s to the 1970s by the first owner/ operator of the facility, McKay Trucking. In June 1975, Kings County issued a Conditional Use Permit (CUP) to McKay Trucking for land disposal of oilfield wastes. In March 1977, Kings County expanded the CUP to include evaporation ponds and land disposal of industrial wastes. McKay Trucking changed its name to Environmental Disposal Services, Inc. (EDS). EDS received a CUP to handle Class I hazardous wastes sometime prior to 1979. In April 1979, Chemical Waste Management, Inc. (CWM) purchased the site from EDS and began to operate a Class I treatment and disposal facility. In 1987, the facility was permitted by the both the Department of Toxic Substances Control and US EPA to accept, store, treat, and dispose of waste Polychlorinated Biphenyls (PCBs). Between 1979 and 1998, the facility operated exclusively as a Class I landfill that treated, stored, and disposed of hazardous waste. In 1998, the facility converted a portion of its Class I landfill (B-19) to a Class II/III industrial non-hazardous/MSW landfill. Prior to the conversion, approximately 3 million cubic yards of hazardous waste had been placed in the unit from 1987 to 1992. A total of 20 landfill units (all but 3 are closed), 20 surface impoundments. (all but 4 are closed), 6 spreading areas (all are closed), and 1 mud pond (inactive) have been constructed at this facility over the past 36 years. The KHF currently has 3 operational landfills. Landfill B-18 is permitted as a 15.6 million-cubic yard RCRA, Non-RCRA and TSCA landfill. Landfill B-19 is permitted as a 7.7 million-cubic yard Class II/III landfill. The liner system in both B-18 and B-19 consists of two synthetic liners combined with two (2) clay liners. A separate leachate collection and recovery system (LCRS) operates within each of the four (4) phases of B-19 and B-18. Incompatible wastes are separated by clean soil (daily cover). Landfill B-17 is permitted as a 17.8 million-yard Class II/III landfill. B-17 is designed with a double composite liner system consisting of a 60-ml thick double-sided textured HDPE and a geosynthetic clay liner. The landfill is designed with a leachate collection and recovery system. Landfill volume survey and computations are periodically completed by a survey crew. In addition, a survey crew provides landfill grid stakes for waste disposal grid tracking and construction stakes for the waste fill plan configuration. 7 © 2021 WM Intellectual Property Holdings, L.L.C.

In addition: • Manifests are tracked and reported in an orderly manner • Records show date and method of treatment, storage and disposal of all waste received by the facility • Manifests are checked against the shipment and profile prior to accepting waste • Records reflect location of each hazardous waste within the facility including cross-references to specific manifest document numbers • Manifests are uploaded to US EPA E-Manifest System. • Manifest copies can be obtained online via customer WM Solutions account. PLANS TO CONSTRUCT ADDITIONAL LANDFILL S Plans are in place to construct Landfill B-20 (Class I) Landfill Design Requirements The design meets or exceeds the requirements of 40 CFR Part 264/265 and the minimum technology standards of the Hazardous and Solid Waste Amendments (HSWA) of November 8, 1984, and EPA guidance documents EPA/530-SW-85-014 (May 24, 1985), EPA/600/2-87/097 (December 1987) and EPA/530-SW-89-047 (July 1989). Presently, Class I waste accepted for disposal in a landfill at the Kettleman Hills Facility is buried in Landfill B-18. The landfill liner system for Landfill B-18 consists of the following elements (from top to bottom): • A 2-foot minimum thickness Operations Layer, constructed from on-site granular material with a maximum 6-inch particle size. The purpose of this layer is to provide a working surface for waste trucks and landfill equipment, and protection against damage to the underlying engineered liner system components. • A 1-foot thick primary leachate collection system consisting of: − A 16-ounce (Trevira 11155) geotextile to function as a filter below the operations layer. − Approximately 12 inches of free-draining granular material, including a 4-inch corrugated HDPE pipe along the flow line. − A geocomposite filter/drainage layer consisting of a Trevira 1155 geotextile thermally bonded to one side of Polynet 3000 geonet. • A low permeability composite primary liner consisting of: − A 60-mil roughened High Density Polyethylene (HDPE) line. − 1.5 feet of compacted clay with a permeability of less than or equal to 10-7cm/sec. • A secondary leachate collection system consisting of: − 16-ounce geotextile to function as a filter below the primary clay liner. − Approximately 12 inches of free-draining granular material. − A geocomposite filter/drainage layer consisting of Trevira 1125 geotextile thermally bonded to one side of Polynet 3000 geonet. − A second geonet layer for an 80-foot width along the entire secondary drainage flow line, above the vadose zone trench. • The low-permeability, composite secondary liner consisting of: 8 © 2021 WM Intellectual Property Holdings, L.L.C.

No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. − A 60-mil roughened HDPE liner. − 3.5 feet of compacted clay with permeability less than or equal to 10-7 cm/sec. •A Vadose Zone liner (see description: Leachate Collection and Recovery System) •The prepared subbase which was graded smooth and proof-rolled to assure that soft or loose subgrade zones did not exist. •The liner configuration used in Landfill B-18 is generally the same as those successfully used for prior KHF facilities with only the following primary modifications: • Roughened HDPE liner is used throughout the landfill and geonet/geotextile composites are used on slope areas to improve stability for the B-18 configuration conditions. • The outside protective liner on the landfill slopes, required to provide temporary ultraviolet light protection to the underlying geotextile consists of a white 40-mil HDPE liner. This material also decreases the clay surface temperatures during the period the sideslopes are exposed to sunlight , thereby reducing the potential for clay desiccation. This white liner is removed as the operations soil is periodically extended up the slope in advance of waste placement. Presently three surface impoundments, P-9, P-14 and P-16, are in use at KHF for the disposal, by solar evaporation, of certain liquid wastes. The liner systems for these impoundments consist of the following (from top to bottom): •A 60-mil primary HDPE synthetic liner •1 foot of compacted primary clay with a permeability of less than or equal to 10-7 cm/sec or less •A 4-oz geotextile filter layer •A one-foot thick, granular drainage layer having a permeability equal or greater than 10-2 cm/sec •A synthetic geocomposite (geotextile/geonet) drainage layer •A 60-mil secondary HDPE synthetic liner •3 feet of compacted secondary clay with a permeability of less than or equal to 10-7 cm/sec or less •The prepared subbase which was graded smooth and proof-rolled to assure that soft or loose subgrade zones did not exist Leachate Collection and Management The main aspects of the leachate collection systems in the KHF active landfills (B-17, B-18 and B-19) are the collection sumps where leachate is collected and removed. Each sump includes the following three leachate collection and recovery zones (from top to bottom): •The Primary Leachate Collection System Zone, which will collect rainfall infiltration through the waste and operations layer. Its design is based on providing adequate pump capacity so that the liquids will not exceed the sump height; to the elevation of the landfill base at the sump perimeter. Typically the primary sump consists of an approximate five-foot thick granular drainage layer. The actual thickness varies with each landfill system with final sizing designed to meet the criteria identified above. A geotextile filter fabric is placed over the drainage gravel to prevent the operations layer soil from infiltrating the gravel and the primary synthetic drainage geocomposite underlies the drainage gravel. •The Secondary Leachate Collection System, which is not expected to normally be affected by rainfall infiltration, but will drain consolidation water from the overlying clay liner and any seepage which may pass through the Primary liner system. The Secondary Leachate Collection system pumps are designed to remove approximately 2,000 gallons per day (gpd) per acre of area served by each particular sump. Actual pump capacity may vary with each particular unit. The secondary sump consists of a 1.5-foot thick granular drainage layer overlain with a geotextile beneath the primary clay. The secondary synthetic drainage geocomposite underlies the drainage grave. •The Vadose Zone Collection System, which is located in a 12-foot wide trench below the secondary composite liner. The purpose for this zone is to detect seepage, if any occurs through the secondary 9 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential.

Some amount of clay consolidation water may be collected in the vadose zone as the weight of the waste is loaded above the 3.5-foot thick secondary clay liner. The vadose zone consists of an 80-mil HDPE liner in the 12-foot wide, 1.5-foot deep trench, which is filled with a granular drainage material. The drainage material is overlain with a geotextile before placement of the secondary clay layer. Each sump area is located so pumps can be provided within the respective gravel collection zones, through pipes located along the adjacent landfill slopes. The primary collection system design also includes a backup pump, in a vertical riser extended upward in segments as the waste is placed. Leachate from each of the three (primary, secondary and vadose) collection zones is pumped to double walled tanks at the top of the landfill side slope. The removed liquids are then either treated in on-site KHF treatment facilities, or trucked off-site for treatment and disposal. The Surface Impoundments, P-9, P-14 and P-16, each have a leachate collection system consisting of a sump containing varying thickness of a granular drainage rock. The rock is wrapped with a geotextile filter fabric. A four-inch diameter, perforated PVC pipe extends the entire length of each pond. This pipe is situated along the centerline of each pond, graded to drain to the center flowline. Liquids pumped from the collection system are placed in adjacent double-walled tanks for removal and either on-site treatment and disposal or trucked off-site for treatment and disposal. Leachate from hazardous waste management units is either solar evaporated or sent off site for wastewater treatment. Leachate from the Class II/III landfills is recirculated back into the landfill it was generated from or it is solar evaporated. Water Supply for use at the Facility Kettleman receives potable well water from the City of Avenal. The water is piped over the hills to the facility and then stored in tanks for use. Hydrogeology Geologic Setting The site is located on the southwestern flank of the North Dome of the Kettleman Hills anticline. Strata underlying the site consist of an interbedded sequence of marine and non-marine sediments from the Pliocene-age San Joaquin Formation and Tulare Formation. These sediments have been deformed into an anticline. Uplift and erosion have exposed portions of the geologic formations. The KHF lies on the west limb of the anticline. The San Joaquin Formation directly underlies most of the active portion of the KHF, with only a small portion of the western edge of the B-17 WMU directly underlain by the Tulare Formation. Beneath the KHF, the San Joaquin Formation trends approximately 50 degrees west of north and dips approximately 30 degrees to the southwest. Site Hydrogeology Groundwater occurs beneath the site in saturated sandstone beds, or water-bearing zones (WBZs), which are isolated hydraulically from one another by siltstone and claystone intervals designated as low- permeability zones. Significant variations in groundwater elevations between adjacent WBZs attest to the hydraulic isolation of individual WBZs. Groundwater depths range from approximately 300 to 520 feet below ground surface. The 12 monitored WBZs at the site are listed from oldest to youngest as Cascajo A, Neverita A, Neverita B, Tuffaceous A, Tuffaceous B, Mya A, Mya C/D, Pecten A, Pecten B, Trachycardium A (Sand No. 10), Trachycardium B (Sand No. 8), and Acila C. Natural background water quality in the San Joaquin Formation is poor. Total dissolved solids (TDS) concentrations range from 1,550 to more than 20,000 milligrams per liter. On March 25, 1988, the CVRWQCB adopted Resolution 88-051, which determined that groundwater contained in the San Joaquin, Etchegoin, and Jacalitos formations, within ½ mile of the KHF’s Surface Impoundments, is not a potential source of drinking water. On August 11, 1989, the CVRWQCB issued Resolution 89-155 regarding the KHF, which included Resolution 88-051 and further stated that the San Joaquin, Etchegoin, and Jacalitos formations were not a municipal or domestic supply of drinking water. In general terms, the hydrogeologic system at the KHF can be characterized by: (1) stratigraphically confined and restricted flow paths, (2) small ambient gradients that are primarily along strike, (3) low or stagnant 10 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential. No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. horizontal groundwater velocities, and (4) geographic and hydraulic isolation from regional groundwater resources. Apparent groundwater velocities for the site generally range from less than 1 to 10 feet per year and lateral groundwater gradients within the individual WBZs generally are along strike. Low groundwater velocities and the lack of identifiable recharge or discharge areas suggest the site groundwater is isolated from regional groundwater resources. Nearest Surface Water There are no bodies of surface water (i.e. ponds, lakes) either on or adjacent to the Kettleman Hills Facility. The nearest surface water, located 11 miles east, is the Kings River. Additionally, the California Aqueduct, about 3.5 air miles east of the site, is not in contact with the local ephemeral drainage of the area. Infrequent precipitation from local storm events is quickly absorbed by the moisture-deficient soils. Only ephemeral drainage is present in the Kettleman Hills area. Several ephemeral terminal streams can be mapped across the KHF site boundaries, draining either southwest toward the Kettleman Plain or east toward the San Joaquin Valley. To the east, they become more poorly defined as the water is either evaporated, is retained in the upper limits of the moisture-deficient soils, or provides a limited amount of groundwater recharge to the valley aquifers. The Kettleman Hills Facility receives an average of 6.40 inches of precipitation per year as measured at the KHF Meteorological Station between the years of 1986 and 2020. The mean evaporation rate for this site is 103 inches per year as measured in Fresno, California. Based upon this data, average annual net precipitation is approximately -97 inches at the site. Nearest Groundwater User The nearest groundwater users are located approximately 4 miles to the northeast in Kettleman City. There is no known hydraulic communication between the KHF San Joaquin Formation groundwater and the San Joaquin Valley Alluvium and Tulare sediments groundwater. Groundwater Monitoring Program Groundwater Monitoring wells: 45 total wells (3 for elevations only) Groundwater Sampling: Quarterly (Class I WMU Wells) Semi-annually (Class II/III WMU Wells) Annually (Class I TSCA WMU Wells) Groundwater Monitoring well depths: 300-feet to 520-feet The Kettleman Hills Facility groundwater monitoring programs and procedures for sampling are completed in accordance with: • The California Central Valley Regional Water Quality Control Board, which administers State Water Resources Control Board regulations, issued Waste Discharge Requirements (WDR) Order R5-2014- 0003, dated January 16, 2014, in compliance with Title 23 of the California Code of Regulations for the construction, operation, and closure of Class I waste management units. • The California Central Valley Regional Water Quality Control Board, which administers State Water Resources Control Board regulations, issued Waste Discharge Requirements (WDR) Order R5-2006- 0122, dated October 26, 2006, in compliance with Title 27 of the California Code of Regulations for the construction, operation, and closure of Class II/III waste management units. • The California DTSC Hazardous Waste Facility Permit 02-SAC-03, dated June 16, 2003, last modified May 21, 2014, in compliance with Title 22 of the California Code of Regulations for the construction, operation and closure of Class I waste management units. Note: Even though this HWFP refers to WDRs “that are specific to hazardous waste disposal operations issued to the Permittee by the Central Valley Regional Water Quality Control Board”, DTSC also requires KHF to follow the 2001 Site-Specific Groundwater Monitoring Plan, which reflects the requirements of rescinded WDR 98-058 (both Class I and Class II/III WMUs.) • The US Environmental Protection Agency, Region IX , which administers Toxic Substances Control Act regulations, issued a TSCA Approval, dated July 29, 2020, in compliance with 40 Code of Federal Regulations Part 761 for the operation and closure of waste management units handling TSCA regulated material. The Kettleman Hills Facility specific groundwater monitoring programs consists of 42 groundwater monitoring wells for sampling the water-bearing zones (WBZ) which outcrop within the active facility limits. All of these WBZ pass beneath the Kettleman Hills Facility in a northwest to southeast direction and dip to the Southwest. 11 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential. No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. The KHF groundwater monitoring system consists of wells of various designations: • Detection Monitoring Wells • Evaluation Monitoring Wells • Evaluation Monitoring Partner Wells • Corrective Action Monitoring Wells • Piezometers and Gradient Wells The Kettleman Hills Facility Site-Specific Groundwater Monitoring Plans and Groundwater Monitoring Reports describe in more detail the permitted groundwater monitoring programs at KHF and are available for review. Also contained in these plans and reports are tables which present the groundwater monitoring coordinates, elevations, pump data and target depth; the wells with their designations and sampling frequencies for listed parameters; and the sampling parameters. Groundwater analytical results and gradients are submitted to the regulatory agencies as required on a quarterly, semi-annual, and annual basis. Status of Corrective Action Monitoring Impacts to groundwater associated with historical operation of five permitted unlined WMUs have included both VOCs and inorganic compounds. Impacts to groundwater have been identified from formerly permitted unlined surface impoundments P-9, P-12, and P-18. Releases have also been identified from closed permitted, unlined landfills B-7 and B-15, which contain drums of liquid waste. The P-9 WMU was retrofitted in 1985 with a double-composite liner. The P-12 WMU, also known as the P-12/12A WMU, stopped receiving waste in 1985 and was closed in 1997 as part of the combined closure. P-18 WMU stopped receiving waste in 1985 and contaminated solids were removed in 1989 during construction of the B-19 WMU. The B-7 WMU stopped receiving waste in 1979 and was closed in 1997 as part of the combined closure. B-15 WMU stopped receiving waste in 1985 and was closed in 1997. Corrective action included closure of WMUs, relining of the surface impoundment P-9, groundwater extraction and treatment, and continued groundwater monitoring. From 1988 until 2005, groundwater impacted by former operations of unlined surface impoundments P-9 and P-12 was extracted and treated. Corrective action now includes continued groundwater monitoring and trend testing of VOCs. Statistically significant increasing and decreasing concentrations of VOCs are routinely identified in the CAM well data sets. Air Quality Assurance Historical Air Studies and Monitoring Programs KHF has a long history of air studies and air data collected on site, which continue to show that operations at the facility have no negative impact on the ambient air: •Ambient Air Concentration studies by CARB, EPA, and independent firms in 1980, 1983, two in 1984, and 1985. •Air Quality Solid Waste Assessment Test Report, 1988, independent firm. •Gaseous Tracer Study at the Chemical Waste Management Kettleman Hills Facility, 1988, CARB. •KHF VOC Air Monitoring Program, over nine years from April 1986 through July 1995. •1994 Topographical, Meteorological and Airborne Contaminant Characterization at Kettleman Hills Facility, independent firm, for DTSC. •California Air Toxics “Hot Spots”, 1996, for SJVUAPCD. •Dioxin-Like PCB Congeners Study, 2009, independent firm, for EPA-IX. Current Ambient Air Monitoring Program On June 16, 2003, the California Department of Toxic Substance Control (DTSC) issued a Part B Permit renewal to KHF. Part III, Section 4, Environmental Monitoring, of the permit required KHF to implement an Ambient Air Monitoring Program (AAMP) that complies with the Environmental Monitoring and Response Programs for Air and Soil-Pore Gas provisions of the California Code of Regulations, Title 22, Section 66264.700, et seq. (Article 17). 12 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential. No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. On July 29, 2020, the US Environmental Protection Agency, Region IX issued a TSCA Approval to KHF. Part VIII, Section A requires KHF to implement an Ambient Air Monitoring Program (AAMP) in accordance with their Part B Permit issued by California Department of Toxics Substances Control. The AAMP is designed to assess facility releases (air emissions) of volatile organic compounds (VOCs), carbonyls, pesticides, polychlorinated biphenyls (PCBs), and PM10 metals in order to evaluate the risk to human health. Under the current California Air Resources Board’s (CARB) sampling schedule, ambient air samples are collected every 12 days over a 24-hour sampling period. There are four permanent AAMP stations, and one portable unit. In addition, beginning in October 2016 the program expanded and now includes collecting monthly-long PCB/Pesticide samples once per quarter at all four monitoring locations. Ambient air monitoring for this AAMP began on October 2, 2006. In May 2011 KHF submitted the Draft 2011 Health Risk Assessment. This HRA was reviewed by DTSC and the US EPA and was revised before being approved as final. The Final 2011 Health Risk Assessment was submitted to DTSC in November 2011 and approved by DTSC on January 12, 2012. This HRA evaluated lifetime cancer risks and noncancer health effects for the following four receptor scenarios: 1) Hypothetical commercial/ industrial worker assumed to work at the KHF property boundary; 2) Ranch worker at the facility boundary; 3) Residential areas in and around Kettleman City; and 4) Hypothetical long-term resident rancher assumed to live at the KHF property boundary. The results of the HRA concluded that the health risks from exposure to KHF emissions were either below benchmark risk levels or within the target risk management ranges identified by the California Environmental Protection Agency (CalEPA), the San Joaquin Valley Air Pollution Control District (SJVAPCD), DTSC, and the US EPA. Annual HRA updates are required in KHF’s RCRA Part B permit. During a conference with DTSC on February 13, 2012, it was agreed that future annual HRA updates would be performed by conducting a screening level HRA analysis each year to determine if exposure risks are substantially different and increasing from the baseline risk. The baseline risk has been defined as the human health risk calculated in 2011 and based on the first four years of AAMP data (October 2006 through September 2010). The annual HRA updates are based on the most recent 12 months of AAMP data then compared to the 2011 baseline. If the screening level analysis indicated a substantial increase in risk, then a more detailed HRA may be required by DTSC. The receptor scenarios to be evaluated would include: 1) the hypothetical commercial/industrial worker assumed to work at the KHF property boundary, 2) the ranch worker at the facility boundary, and 3) residential areas in and around Kettleman City. Storage The KHF is permitted to store containerized RCRA and TSCA solids and liquids. All containers held in storage are inspected daily and inventoried weekly to ensure containers are not leaking or damaged. The movements of containers into and out of storage are tracked and recorded. Both movement tracking and physical inventories are maintained in hardcopy and electronic format. CONTAINER Currently, the Kettleman Hills Facility is permitted to store up to 9,000 55-gallon equivalent drums (double stacked) in our covered storage building. Drums are processed after visual inspection and sample screening (if required) confirms waste is in conformance. Shipments are regularly scheduled to other units for on-site treatment and disposal. Qualifiers: TSCA (PCB) waste cannot be stored in the drum storage unit (but is stored in a separate building). Materials listed under Prohibited and Unacceptable Wastes at the Kettleman Hills Facility are not permitted for storage. The drum storage unit has a concrete pad with dikes and sumps to separate incompatibles and for secondary containment. It is also underlain by an HDPE secondary liner system. All drums are protected from direct rainfall by the roof. There is no run-on/run-off. Any liquids which collect are managed on-site. Daily compliance inspections are conducted for drum condition, labeling and spill containment. BULK CONTAINER STORAGE UNITS Total Capacity Phase I 70 – 20 cubic yard roll-offs container equivalents (treated waste) Phase II 70 – 20 cubic yard roll-offs container equivalents (untreated or treated waste) 13 © 2021 WM Intellectual Property Holdings, L.L.C.

TANKS At KHF, aboveground storage tanks (ASTs) can be divided into three types; ASTs used for storage or treatment of customer waste, ASTs used for storage of petroleum products for site usage, and ASTs used for the collection of site-produced leachate. All ASTs meet or exceed all federal, state, and local requirements. This includes, where applicable, secondary containment, corrosion protection, high-level alarms, daily inspections for both tanks and monitoring systems, and annual tank thickness testing. Underground Storage Tanks (USTs) at KHF are only used for the storage of pure petroleum products for site usage. No USTs are used for storage or treatment of customer waste. All USTs are permitted with Kings County Environmental Health Services, and meet or exceed all federal, state and local requirements. This includes secondary containment, corrosion protection, interstitial alarms, high level alarms, daily inspections of monitoring systems, and annual tank, pipe and alarm testing.

SURFACE IMPOUNDMENTS Currently, the Kettleman Hills Facility operates three (3) solar evaporation units. Each unit is designed with a double synthetic liner system coupled with two layers of clay. A leachate collection and recovery system is also in place at each unit. The Kettleman Hills arid climate allows for an annual evaporation rate of 103 inches per year and an average rainfall of 6 inches. Following is the maximum capacity of the three permitted surface impoundments at KHF: Total Capacity P-9 4,400,000 gallons P-14 2,100,000 gallons P-16 3,900,000 gallons QUALIFIERS Aqueous Liquids with less than 10% solids, less than 100 ppm total volatile organic, no Land Restricted Hazardous wastes unless first treated, no odorous material. Dikes Certification of the surface impoundment dikes are inspected as required by the provisions of the KHF RCRA Permit. Inspections of the condition of perimeter dikes for erosion, breaching and seepage is completed weekly by KHF personnel as part of the Facility Inspection Program Plan. Freeboard Staff gauges have been placed in the surface impoundments to measure the freeboard remaining. Daily observations are made and recorded by site personnel as a part of the Facility Inspection Program Plan. The elevations of the staff gauges and the tops of the liners of the surface impoundments are surveyed annually to determine correction factors to be applied to staff gauge readings. Receiving REQUIREMENTS FOR SHIPMENT SCHEDULING Shipments are generally received between 8:00 am and 5:00 pm. All shipments for the Final Stabilization Unit and the Drum Storage Unit must arrive prior to 3:00 pm, unless prior arrangements have been arranged with the site.

This document is proprietary and confidential. No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. All shipments must be scheduled. Customers can reach the Scheduling Department at 559 386 6107, or by email at KHFTrans@wm.com. At least 48-hours notice is requested. Loads will not be accepted for scheduling unless ALL paperwork is complete and in place (i.e. profile approved and signed, contract approved and signed). Weekend waste acceptance, or other special arrangements must be obtained prior to receipt of shipments. Contact the Scheduling Department to make special arrangements. STORAGE CApACITY Storage capacity is limited. Scheduling of storage material must be pre-approved by Site Management at least 48 hours in advance of shipment. Contact the Scheduling Department to make arrangements. Stabilization and encapsulation space is subject to availability. Trucks for these treatment services must arrive before 3:00 pm. RECEIVING WASTE lOADS • Loads arriving at the facility will stop at Security to check in. • Trucks will either proceed directly to the untarping racks or they will get in line to the untarping racks. NOTE: Trucks are not allowed to untarp their loads prior to the untarping racks. • After untarping their trucks, the trucks will proceed to the sample racks where the load will be visually inspected and, if required by the facility Waste Analysis Plan (WAP), be sampled for a fingerprint analysis. The driver will hand the manifest to the sampler. The sampler will generate site-specific paperwork using information from the manifest. Manifest information will also be used to populate the sample label if a sample is required. Note, if a sample is required, the sample will be placed in a sealed plastic bag prior to handing it to the driver. This sealed plastic bag acts as a custody seal while the sample changes hands. The manifest, the site-specific paperwork and the sample, if required, will be handed to the driver. • The driver will then proceed to the inbound scale. At the scale, the driver will hand the manifest, site- specific paperwork and sample (if required) to the scale attendant. Once the truck is weighed in, the driver will be directed to stage on Unit B-15 while the paperwork is being reviewed and the sample (if required) is analyzed. The paperwork and sample (if required) will be sent over to the Receiving Department via a vacuum tube system. • The driver will either wait at his truck or at a designated area near the Receiving Department to be released to off-load. Receiving will contact the driver via radio or verbally at the window when the load has been released to off load. The Receiving Department will hand the driver only a copy of the site- specific paperwork that identifies what unit the load is approved to off load at. The driver will be instructed as to what unit the load is to be taken to. • The driver will take the load to the appropriate waste management unit. Prior to offloading the waste, the paperwork must be reviewed and signed off by a site employee at that unit. This is to confirm that the driver is in the correct location. • Once the offloading process is complete, the driver will proceed to the outbound scale with the site- specific paperwork provided by the Receiving Department. The driver will hand the scale attendant the site-specific paperwork. A light weight will be obtained and the driver will be handed their manifest and a copy of the weight ticket. • The driver will stop at Security and then exit the facility to Highway 41. SPECIAL NOTE: overnight parking is not available at the site. 17 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential.

Transportation CONVENIENT TRANSPORTATION PROVIDED With its large integrated transportation network, transportation alternatives to KHF are diverse and convenient. Our transportation specialists work with customers to develop the most cost-effective transportation option available. TRANSPORTATION EPA IDENTIFICATION NUMBER KHF uses a network of permitted hazardous waste haulers and thus does not have its own Transportation EPA ID number. STATE AGENCY ISSUED STATE MANIFEST FORMS The state agency does not issue state manifest forms. CONTAINER SHIPMENT GUIDELINES To ensure the safety of all handlers of the hazardous waste from the generator to the Kettleman Hills Facility, and to minimize the likelihood of accidental spills in transport, the KHF can accept shipments via a number of transportation methods as discussed below. BOTTOM DUMP VEHICLES On a case-by-case basis, the KHF can handle bottom dump vehicles. This must be pre-approved by the site. Make arrangements by contacting your Industrial Account Manager, who will contact the site to make arrangements. REQUIREMENTS FOR BULK DUMP TRUCKS AND ROLL -OFF BOXES To ensure that the trailer maintains its integrity and does not emit hazardous wastes to the environment while in transit, all solid waste loads should be lined with minimum 6-mil. visquene, plastic, or the equivalent completely encasing the load. Dusty material must be bagged and sealed to ensure minimal air dispersion of waste during off-loading. Any questions on trailer lining or bagging should be directed to the appropriate sales office for resolution. To prevent leaks, trailer tailgates should be tightly secured with spreader chains or other equivalent devices. To minimize the incidence of spills, all loads should be carefully inspected for leakage prior to departure from the generator’s site and periodically enroute. Under no circumstances will drummed hazardous waste be accepted in bulk dump trucks. Dump trucks and roll-off boxes are required to be tarped. The Generator and Transporter are responsible for complying with applicable packaging and transportation requirements. REQUIREMENTS FOR FLATBED SHIPMENTS Arrangements must be made in advance through the Scheduling Department. Heavy articles (> 10,000 pounds) will require a third party crane service to offload the items. Crane arrangements are to be made by the customer and coordinated with the site. All waste items must be able to be picked or lifted from the flatbed. KHF personnel will not push materials off of a flatbed. According to the Occupational Safety and Health Administration, it is the transporter’s responsibility to provide flatbed vehicles with sound cargo decks. The DOT regulations specify that incompatible wastes should be segregated with physical barriers, and containers must be properly secured. The condition of containers should be carefully checked. Drivers should not accept leaking or badly corroded containers for transport. Transportation of open drums is not permitted by DOT regulations and will not be accepted. TANKER TRUCK DELIVERY REQUIREMENTS Tankers must contain only one manifested waste. The DOT regulations in 49 CFR §178 specify material standards for containers used to transport chemical cargoes. All valves, hoses, and pumping equipment should be in good condition with tight gaskets and seals to prevent leakage. The transport driver is responsible for decontaminating all fittings, valves, and caps before the vehicle departs the facility. Drivers are not to open the domes until they are parked at the sample rack. After a sample has been taken, the driver must secure the dome closed before moving the truck. VAN SHIPMENT REQUIREMENTS Drums and articles must be properly secured prior to leaving the generator’s location. If the van load contains containers destined for an additional location, they must be at the front of the trailer. KHF will not offload containers that are not destined for the KHF. REQUIREMENTS FOR SHIPMENTS OF HAZARDOUS WASTE All heavy-duty diesel trucks delivering material on a uniform hazardous waste manifest to the KHF must be equipped with a 2010 or newer engine. Upon first shipment to the site, each truck engine will be inspected for the presence of an Emissions Control Label to verify the engine year prior to acceptance. Trucks will be provided with a unique ID sticker to expedite future deliveries. Material delivered on a 2009 or older engine will be rejected back to the generator. 18 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential.

Analytical Capabilities and Waste Acceptability CORRABORATIVE TESTING KHF requires corroborative testing on wastes that have been treated or naturally meet treatment standards prior to approval. TYPES OF ANALYSIS CONDUCTED IN THE LABORATORY Equipment Capabilities • pH • Wet Chemistry • Flashpoint • Total Cyanide by Method 9010 Analyses • Wet Chemistry: Cyanide analysis; sulfides; paint filter test, flash point test • Screening tests: Physical description; water compatibility; pH; flammability potential; cyanide screen; sulfide screen; oxidizer screen • Stabilization Treatment Evaluation Program (see Final Stabilization Unit information) A QA/QC program developed and managed by Waste Management has been fully implemented and is being fully utilized. Analytical Capabilities The Kettleman Hills Facility maintains an on-site lab staffed with a full-time chemist and technicians capable of conducting most tests required for waste approval, incoming waste analysis and post-treatment certification testing. The Kettleman Hills Facility currently utilizes NELAC or California ELAP certified laboratories for samples requiring PCB, organics, and/or metals analysis. INCOMING WASTES SAMPL ING AND ANALYZING All waste shipments are visually inspected. Unless identified as a sampling exception in the Waste Analysis Plan (WAP), in order to identify waste properties and ensure the acceptability of waste shipments of drums or portable tanks, a representative sample is obtained from each container of a waste shipment. When ten or more containers of a single waste stream are received, one composite sample will be taken for every 10 drums/containers. With the exception of municipal solid waste (MSW) loads, all bulk waste shipments are visually inspected. If the waste stream is not listed as a sampling exception in the WAP, a representative sample of the waste stream will be obtained for mandatory analysis. All shipments will be visually inspected. Bulk event projects where more than one load is received from one profile (for example, a major site cleanup of contaminated soil), if required to be sampled by the WAP, at least 10% of the shipments will be sampled and analyzed. The Waste Analysis Plan may be viewed on-site. Case-by-case discrepancies (non-conforming wastes) from the original profile will be brought to the attention of Management, and the generator will be contacted in order to resolve these discrepancies. If the physical state of the material changes enough to require a different disposal method, these changes will be addressed with the generator, and the generator’s approval will be required for further handling of the waste. Generator is responsible for all non-conforming waste. Submission of a new waste profile may be required along with additional information on the process generating the waste for wastes that are non-conforming. Profile amendments may also be required and must be authorized by the generator and approved at the Technical Services Center prior to managing the waste. Waste Acceptance Criteria PRE-DISPOSAL REQUIREMENTS All wastes require a completed and signed waste profile, along with any supporting analytical or other information used during the waste characterization process, to be submitted to the Western Technical Service Center (WTSC) for review and approval. Waste Approval Managers (WAMs) will review the profile for completeness and accuracy and determine whether the waste is acceptable for management at the Kettleman Hills Facility based on federal and state regulations and facility permits. The WAMs will also determine how the waste will be managed at KHF and what documentation, such as completed Land Disposal Restriction forms, must accompany the shipments. The WAMs will coordinate with the site as to whether a pre- acceptance sample is necessary to determine the treatment method and the reagent ratios needed to effectively treat the waste below the treatment standards.

SUBMITTAl OF pApERWORK All paperwork is to be submitted on the WMSolutions web page. SUBMISSION OF NEW pROFIlE OR RECERTIFICATION pApERWORK When the waste approval decision is about to expire, a notification letter will be sent to the generator along with a copy of the completed waste profile. The generator should review the waste profile and make all necessary corrections and modifications. The updated profile should then be sent to the site. If the waste changes at any time, or the process generating the waste undergoes change, a new profile must be submitted, along with a sample. TYpES OF SAMplES NEEDED FOR DISpOSAl AppROVA l The WAM will coordinate with KHF to determine if a pre-acceptance sample is required. If a sample is required the generator will need to provide the following to the KHF: • Two one-quart samples properly labeled with the Generator Name, Profile #, Sample Date, Sample Time, Name of Sampler • Copy of the Profile • Completed and Signed Chain of Custody EXCEpTIONS TO SAMplE REQUIREMENTS The following waste streams are exempt from sampling and fingerprint analysis: • Lab packs • Empty containers • Single substance contaminant • Commercial products or chemicals that are off-specification, outdated • Asbestos-containing waste • Beryllium-containing waste • PCB contaminated articles, equipment, debris and solids • Waste that is visually identifiable through an inspection process (Examples include batteries, lights, lamps, filters) • Debris as defined in 40 CFR Part 268.2 or 22CCR 66268.2 • Controlled substances regulated by the Federal Government including illegal drugs and/or materials from clandestine labs • Non-RCRA California hazardous waste • Materials designated for storage and subsequent transshipment off-site • Contaminated PPE % OF INCOMING WASTE SAMplED If a waste is required to be sampled by the facility WAP, every shipment is sampled for fingerprint analysis with the following exceptions: Bulk event projects where more than one load is received from one profile (for example, a major site cleanup of contaminated soil), if required to be sampled by the WAP, at least 10% of the shipments will be sampled and analyzed. When ten or more drums/containers of a single waste stream are received, one composite sample will be taken for every 10 drums/containers. pARAMETERS FOR ANAlYSES ON SAlES SAMplES If sales samples are required, parameters are pH, cyanide screen, sulfide screen, oxidizer screen, flammability screen, water reactivity, and physical description. Metals analysis for recipe development is currently sent off site for analysis by a third party laboratory. Total and amenable cyanide, if needed, may be analyzed on site or sent to a third party laboratory. pARAMETERS FOR ANAlYSES ON INCOMING WASTE Wastes that are required by the facility WAP to be sampled and analyzed are subjected to the mandatory fingerprint analysis, which includes: • pH • cyanide screen • sulfide screen • oxidizer screen • ignitibility potential • water reactivity • physical description Additional supplemental analyses may be conducted in order to further evaluate the waste and to confirm that the waste matches the information on the waste profile. 24 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential. No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. ACCEPTANCE OF E&P (OILFIELD) WASTE Kettleman is permitted to accept E&P (Oilfield) Waste. If the waste is considered NORM or TeNORM, the generator must certify that the waste is not regulated under California’s Radiation Control Law. Radiochemistry analysis may be required. These waste streams are subject to profile review and approval. ACCEPTANCE OF PCB WASTES PCB solids, capacitors, light ballasts and associated debris can be landfilled on site. The Kettleman Hills Facility offers draining, flushing and disposal for PCB transformers. PCB oil and the flush solution is decanted into a 5,900 gallon storage tank and transported for incineration. Qualifiers: Definition of a small capacitor is less than 2.5 lbs. fluid, less than 7.5 lbs. total gross weight or less than 83 cubic inches in size. The bulk storage tank is not permitted for RCRA material. Water content must remain less than 10% for bulk storage. 1 5,900-gallon tank 240 55-gallon drum equivalent total drum storage capacity REJECTION OF WASTES The facility will make every effort to resolve and process the waste in accordance with all regulations prior to rejection. The waste would be rejected for certain reasons, including if: 1) it is non-conforming to the profile and cannot be managed at our facility or transhipped to an alternative facility for treatment; 2) the generator requests that we reject it; 3) the transporter’s equipment malfunctions and the driver is unable to unload the waste; or 4) the transporter’s truck is equipped with an engine older than 2010 and the transporter is making an attempt to deliver waste on a hazardous waste manifest to the KHF (permit condition). Prohibited and Unacceptable Waste PROHIBITED WASTE STREAMS • Radioactive waste prohibited from land disposal under California’s Radiation Control Law • Infectious Material/Etiological • Forbidden and Class A Explosives • Compressed Gasses • Certain RCRA coded waste streams specifically prohibited by the KHF RCRA Part B permit Waste Analysis Plan KHF has a Waste Analysis Plan set forth in accordance with 40 CFR 264.13. This plan is available at the facility at all times. 25 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential.

This document is proprietary and confidential. No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. Services and Treatment Capabilities Macroencapsulation The Macroencapsulation process at the KHF utilizes a containment unit made from high density polyethylene (HDPE) to ensure the non-leachability of waste meeting the RCRA definition of debris found at 40 CFR Part 268.2(h). Hazardous debris of irregular shapes or debris that cannot be microencapsulated because all exterior and interior surfaces cannot be coated with encapsulation agents are placed into the WM patented one piece, 20-cubic yard containment box (often referred to as a “vault”). Void spaces surrounding the debris are filled with non-cohesive soil or soil-like fillers, sand, cement, other non-degradable space fillers. A lid made of HDPE is placed on top of the filled containment vault and secured using an adhesive and screws. The sealed, secure container is transferred to the RCRA Subtitle C landfill for safe, permanent disposal. Macroencapsulation is appropriate for almost any hazardous debris that fits into the 20-cubic yard “vault”, including pipes, hoses, concrete, filters, rags, motors, crushed containers, and other debris materials. Process residuals except in minimal quantities are not allowed. Microencapsulation Hazardous waste materials meeting the RCRA definition of debris found at 40 CFR Part 268.2(h) that can be coated can be managed via microencapsulation. This process involves coating waste materials of simple geometric shapes with a customized mixture of proprietary fixation reagents that significantly reduce the potential leachability of hazardous constituents into the surrounding landfill environment. Some fixation reagents used in the microencapsulation process include lime kiln dust, Portland cement, fly ash, or similar materials. Once the coating process has been completed, the encapsulated waste materials are transferred to the RCRA Subtitle C landfill for safe, permanent disposal. Hazardous debris contaminated with metals is treatable utilizing WM’s microencapsulation technology and it is the preferred treatment method for debris that can be fully coated on all surfaces, such as bricks, rocks, and smaller pieces of concrete. PCB/TSCA The KHF facility is permitted to accept certain PCB bearing TSCA wastes including PCB transformers and large capacitors for draining and flushing on-site, as well as PCB solids, small capacitors, light ballasts, drained and flushed PCB transformers and large capacitors, and other associated debris for secure landfill on-site. PCB oils and flush solutions generated from the draining and flushing of transformers and large capacitors are temporarily stored in on-site tankage located within secondary containment units before being sent off-site for incineration. Small capacitors are defined as containing less than 2.5 lbs. of fluid, and having a total gross weight of less than 7.5 lbs. or being less than 83 cubic inches in size. PCB capacitors not meeting these size/ weight requirements are considered large capacitors and must be drained and flushed similar to PCB transformers before carcass disposal in the secure landfill. Secure Landfill Modern day secure landfills in the U.S. permitted for the permanent disposal of hazardous wastes are some of the most secure treatment and disposal facilities in the world. Landfill disposal cells are used for the secure, permanent disposal of solid RCRA hazardous, industrial, certain TSCA regulated, and non-regulated wastes; as well as State-only hazardous waste. Active disposal cells have composite liners consisting of compacted clay and bentonite, and double layer High Density Polyethylene (HDPE). Each cell is a part of a “disposal unit” that also includes a sophisticated leachate collection system, groundwater monitoring wells, and a state-of-the-art leak detection system. Once wastes are profiled, reviewed, and approved for landfill acceptance, the materials are placed in the disposal cells in horizontal lifts with all waste placements identified on a 3-dimensional coordinate system. 26 © 2021 WM Intellectual Property Holdings, L.L.C. This document is proprietary and confidential. No part of this document may be disclosed in any manner to a third party without prior written consent of Waste Management. Solar Evaporation The Kettleman Hills facility operates three (3) solar evaporation units that are each designed with double synthetic liner systems coupled with two layers of clay and a leachate collection/recovery system. Waste suitable for treatment by solar evaporation at the facility must be aqueous liquids with less than 10% solids. Additional qualifiers include: VOC’s <100ppm, metals must be below the California Aqueous Metals standards, no Land Restricted hazardous wastes unless first treated to meet Land Disposal Restrictions treatment standards, and no odorous materials. The total capacity of three solar evaporation units is 10,400,000 (P-9 = 4,400,000 gallons, P-14 = 2,100,000 gallons, and P-16 = 3,900,000 gallons). Certification of the unit walls (dikes) is conducted weekly via inspections as required by the site RCRA permit and gauge readings measuring freeboard in each unit are recorded by site personnel daily. Kettleman Hills arid climate allows for an annual evaporation rate of 103 inches per year and an average rainfall of 6 inches per year. Solidification Waste Management’s trademarked LiquifixSM solidification process is utilized to solidify waste containing free liquids into solid materials that pass the Paint Filter test before being landfilled. The process utilizes drying agents, usually in the form of cement or cement by products such as cement kiln dust, fly ash, or Portland cement, to dry liquid, sludge, or waste of other physical state that contains free liquids into solid materials that can be managed in landfills. Waste streams routinely treated via WM’s LiquifixSM technology are generally non-RCRA hazardous wastes and include off-spec products, brine wastes, ink sludge, grease trap wastes, non-hazardous paint sludge, certain waste water treatment sludge, and a multitude of other waste streams Stabilization The stabilization process occurs when waste are mixed with lime bearing materials such as cement, cement kiln dust, lime, flyash, other proprietary agents, and water inducing chemical reactions that result in the reduction of mobility (or leachability) of hazardous components within a hazardous waste matrix. Process recipes are developed for each waste stream and post treatment TCLP analysis are performed to confirm the recipe will treat the waste stream to below Land Disposal Restriction standards. After stabilization of the waste has occurred, the stabilized material is transferred to the RCRA Subtitle C landfill for safe, permanent disposal. 27 © 2021 WM Intellectual Property Holdings, L.L.C.

R5-2006-0122 WASTE DISCHARGE REQUIREMENTS FOR CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19, BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY The California Regional Water Quality Control Board, Central Valley Region, (hereafter Regional Water Board) finds that: 1. The Chemical Waste Management, Inc. Kettleman Hills Facility (KHF) is one of five Hazardous Waste Landfill Facilities and one of nearly 300 Municipal Solid Waste Landfill sites that Waste Management, Inc. operates in North America. Waste Management, Inc., the largest waste management corporation in the world, also currently has ten bioreactor projects in operation (one in Canada). The KHF currently accepts for disposal approximately 1,400 tons per day of municipal solid waste (MSW) and approximately 4,000 tons per day of hazardous and designated wastes, mostly from sources within the State of California. 2. The McKay Trucking Company began disposal operations at the KHF in March 1975. In 1979, Chemical Waste Management, Inc. (hereafter Discharger), a wholly-owned subsidiary of Waste Management, Inc. of Texas, purchased the facility and is the current owner and operator. 3. The Discharger submitted a Joint Technical Document (JTD) dated 29 September 2005 for the operation of a bioreactor project and a control unit within the Class II/III Landfill B-19, and a JTD for new Class II/III Landfill B-17 dated 10 July 2006. The JTDs fulfill the requirement for submission of a Report of Waste Discharge. Other technical reports regarding site characteristics, facility design, monitoring, operations, and closure have also been submitted. 4. On 27 February 1998, the Regional Water Board adopted Waste Discharge Requirements (WDRs) Order No. 98-058 that currently regulates the disposal of liquid and solid hazardous wastes, and the disposal of non-hazardous liquid and municipal solid wastes and designated wastes at the facility. The new WDRs will regulate the disposal of designated solid waste and MSW to proposed Landfill B-17 and the Landfill B-19 Control Unit in accordance with Title 27, California Code of Regulations (CCR), Section 20005, et seq. (Title 27). The new WDRs will also regulate the disposal of designated solid waste, MSW, and the addition of supplemental liquids to the Landfill B-19 Bioreactor in accordance with Title 27 and State Water Resources Control Board (State Water Board) Resolution No. 93-62, once the pending amendments to the resolution are approved by the U.S. EPA. The Discharger has been accepting MSW and non-hazardous designated solid waste into Landfill B-19 since 1998. The closure of Landfill B-17, the Landfill B-19 Bioreactor, and the Landfill B-19 Control Unit will also be regulated by these WDRs. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -2- 5. On 22 March 2004, the U.S. EPA added Section 258.4 to the federal MSW regulation requirements, for the purpose of developing and demonstrating advanced landfill operation methods, such as bioreactors, as long as specific conditions are met. The section allows states to issue research, development, and demonstration (RD&D) permits, which in this case would be in the form of these WDRs allowing the addition of supplemental liquids to the Landfill B-19 Bioreactor. Liquids cannot be added to the Landfill B-19 Bioreactor until the U.S. EPA grants formal approval of the 21 July 2005 revisions made to amended State Water Board Resolution No. 93-62. 6. When amended Resolution No. 93-62 is formally approved by U.S. EPA, the portions of the WDRs relative to the RD&D bioreactor project for liquid additions to the Landfill B- 19 Bioreactor are to remain in force for a period not to exceed three years. The WDRs can be renewed for liquid additions to the bioreactor unit every three years for a total period not to exceed 12 years. 7. This Order implements Title 27 for the construction, operation, and closure of the Class II/III Landfill B-19 Bioreactor and Control Unit, and Class II/III Landfill B-17. LOCATION AND DESCRIPTION 8. The site is approximately one mile north of State Route 41 and about 2.5 miles west of the intersection of Interstate 5 and Route 41, as shown in Attachment 1, which is attached to and made part of this Order. Attachment 2 is also attached to and made part of this Order. The nearest occupied residence to the KHF is approximately 3.5 air miles to the northeast near Kettleman City. 9. The presently authorized waste management area includes 499 acres of the 1,600-acre parcel and extends generally in a northwest to southeast direction across Section 34, T22S, R18E, and across Section 3, T23S, R18E, MDB&M, as shown in Attachment 2, (Assessor Parcel Nos. 038-330-001, 038-330-019, 038-330-020, 038-320-015, 038-320- 020, 038-320-021, and 038-310-005). 10. Land in the vicinity of the Discharger's property is used for oil and gas production and a limited amount of cattle grazing. 11. Site topography is characterized by rolling hills and incised drainages, with elevations varying from 700 to 1015 feet mean sea level. 12. The facility is not in a 100-year flood plain based on the Federal Emergency Management Agency’s Flood Insurance Rate Map, Community Panel Number 060086 0275B. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -3- 13. As required by the General Permit for Discharges of Storm Water Associated with Industrial Activities, the Discharger filed a Notice of Intent on 16 February 1996 and is to submit annual reports as required by the General Permit. 14. The average annual precipitation is 6.61 inches and the average annual pan evaporation is 102.1 inches. The probable maximum precipitation in a 24-hour period is 7.4 inches. The 1,000-year, 24-hour precipitation event is 3.3 inches. 15. The nearest surface water, the California Aqueduct, is about 3.5 miles east of the site at its closest point. GEOLOGY & HYDROGEOLOGY 16. The KHF lies on the west side of the North Kettleman Dome where the Tulare, San Joaquin, and Etchegoin formations trend approximately 50 degrees west of north and are tilted to the southwest at 25 to 35 degrees. Landfill B-19 and proposed Landfill B-17 lie on the San Joaquin formation and the lower Tulare formation (southwest corner of Landfill B-17 only), where the surface exposures of the formations consist of interbeds of marine sandstone, siltstone, claystone, and minor amounts of limestone. Detailed geologic studies conducted at the site have shown that the San Joaquin and lower Tulare formation interbeds are laterally and vertically continuous. 17. Sandstones that can transmit landfill gas (LFG) and groundwater within the San Joaquin formation are targeted for methane gas monitoring and groundwater detection monitoring. 18. No known Holocene faults exist within 200 feet of waste management units (WMUs) or the facility. In accordance with the most current geotechnical and seismic engineering practices, the Discharger determined a mean peak horizontal ground acceleration of 0.57g. This acceleration was based on an assumed maximum credible earthquake (MCE) of Ms 6.6 on a ramp thrust fault rupturing at 10 km depth beneath the site. 19. Landfill B-19 is, and proposed Landfill B-17 will be, designed to withstand the MCE without significant damage to their respective containment and cover systems. 20. The WMUs are not known to be in areas subject to rapid geologic change. 21. Over 20 years of analytical data from existing groundwater monitoring wells in both the San Joaquin and lower Tulare formations indicate that the groundwater is of poor quality. Total dissolved solids (TDS) range from 1,550 to greater than 10,000 mg/l. The depth to groundwater ranges from approximately 300 feet to greater than 500 feet below the ground surface. The well yields are low, ranging from 0.25 gpm to 5.5 gpm. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -4- 22. Groundwater flows predominantly to the southeast at less than 10 ft/year. The average drop in groundwater elevation is 2 ft. per 1,000 ft. or .002 ft./ft. 23. Approximately 1.5 miles west of the KHF, wells in the Kettleman Plain area are used for stock watering, irrigation, and domestic water supply. These relatively shallow wells produce good quality groundwater from Alluvium and upper Tulare formation aquifers from depths of 200 to 1,000 feet. WMUs at the KHF are/will be constructed on top of the San Joaquin formation and beds of the lower Tulare formation. The San Joaquin formation and beds of the lower Tulare formation are tilted 25-30 degrees to the southwest and plunge several thousand feet below the Kettleman Plain. These formations contain poor quality groundwater as stated in Finding No. 21. Several hundred feet of impermeable claystone and siltstone interbeds separate the deeper San Joaquin formation and lower Tulare formation from the shallower Alluvium and upper Tulare formation aquifers, isolating and preventing any groundwater flow between the formations. 24. Approximately 3.0 miles east of the KHF and east of the North Kettleman Dome, groundwater wells in the Kettleman City area are used for irrigation, industrial supply, and domestic and municipal water supply for Kettleman City. These relatively shallow wells produce good quality groundwater from Alluvium and upper Tulare formation aquifers from depths of 300 to 1,000 feet. As stated in Finding No. 23, WMUs at the KHF are/will be constructed on top of the San Joaquin formation and lower Tulare formation that tilt to the west away from the Kettleman City area. Erosion of the upper and lower Tulare and San Joaquin formations in the central portion of the dome lying between the KHF and Kettleman City has completely removed these formations between the two areas, thus preventing any possibility for groundwater flow from the KHF towards Kettleman City. Therefore, disposal and treatment operations at the KHF cannot affect groundwater wells in the Kettleman City area. 25. There are no known groundwater supply wells being used within one mile of the facility property boundary line. The closest well on record is a domestic well located approximately 1.9 miles due west of the KHF property boundary line (Meredith/Boli & Associates, 1985). Regional Water Board Resolution No. 89-155, adopted by the Regional Water Board on 11 August 1989, resolved that groundwater contained in the San Joaquin, Etchegoin, and Jacalitos formations within approximately one-half mile of the area permitted for waste disposal is not a municipal or domestic supply (MUN). The groundwater has no demonstrated beneficial uses other than for minor stock watering and industrial usage if sufficient quantities could be obtained. HISTORY OF LANDFILL B-19 26. Landfill B-19 was originally permitted as a 40-acre Class I hazardous waste landfill with a total capacity of approximately seven million cubic yards. Constructed in four phases (IA, IB, II, and III as shown in Attachment 3) between 1986 and 1989, it began receiving Class I waste in 1987. Attachment 3 is attached to and made part of this Order. The WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -5- containment system for each phase was constructed in accordance with the Article 4 Construction Standards for Class I Units contained in CCR, Title 23. In March 1988, after placement of approximately one million cubic yards of Class I waste in Phase IA, a portion of the liner system failed, sliding with a horizontal and vertical displacement of the waste. No waste escaped the unit. 27. After notification of federal, state, and local agencies, all of the approximately one million cubic yards of Class I hazardous waste was transferred from Phase IA to Phases IB, II, and III of Landfill B-19. A temporary synthetic cover was placed over the slope and floor of the damaged Phase IA to prevent precipitation/stormwater runoff from entering. 28. Through 1992, approximately three million cubic yards of Class I hazardous waste was discharged into Phases IB, II, and III of Landfill B-19. The landfill was then deactivated and a 40-mil geomembrane was constructed over the waste as interim closure. 29. In 1998, a portion of Landfill B-19 was converted to a Class II designated waste and Class III MSW disposal unit. Damaged and weathered portions of the Phase IA secondary composite base and sideslope liner systems were removed and repaired, and a new Phase IA primary composite base liner system and primary leachate collection and removal system (LCRS) were constructed as indicated in Finding No. 34. MSW was first received in Landfill B-19 Phase IA on 2 November 1998. 30. A separation liner, covering approximately 16 acres, was constructed over the Class I hazardous waste in Phase IB and a portion of Phases II and III up to the southern limits of the proposed Bioreactor Control Unit shown in Attachment 2. A review of separation liner Construction Quality Assurance (CQA) reports, by both Regional Water Board and Department of Toxic Substances Control staff, indicated that the liner was constructed in accordance with the approved closure plan. Both MSW and designated waste have been placed over the separation liner. The liner is the final cover for the Class I hazardous waste in that area, and has been designed to preclude leachate and landfill gas migration from the overlying Class II/III non-hazardous waste to the underlying hazardous waste. The separation liner design, as described in Finding No. 35, was approved through the adoption of WDRs Order No. 98-058. WASTE MANAGEMENT UNIT OPERATION & DESIGN Landfill B-19 31. This Order will, upon U.S. EPA approval of amended State Water Board Resolution No. 93-62, permit the addition of supplemental non-hazardous liquids to the Landfill B-19 Bioreactor that consists of the 18.23-acres of Class II/III non-hazardous waste lying within Landfill B-19 Phase IA. No liquids will be added to the 11.73-acres of Class II/III non-hazardous waste within the proposed Control Unit. No Class II designated waste or Class III municipal solid waste will be placed over the Class I hazardous waste south of WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -6- the Control Unit (see Attachment 2). This 11.1-acre area has been capped with a closure cover that was approved by the Regional Water Board and the Department of Toxic Substances Control. The closed portions of Landfill B-19 containing Class I hazardous waste will continue to be regulated by WDRs Order No. 98-058. 32. An engineered, earthen stability berm has been constructed around the eastern and southern perimeter of Landfill B-19 with a portion of the berm constructed over the closure cover system in the 11.1-acre area described above. The berm is designed to provide stability of the landfill during the maximum credible earthquake. 33. Landfill B-19 is designed with a total volume of approximately 3.99 million cubic yards (including the final cover). Assuming the final cover consists of a 4-foot thick soil cover (evapotranspirative cover), Landfill B-19 will contain approximately 3.82 million cubic yards of Class II/III non-hazardous waste. 34.

The containment system described in Table 1 for the Landfill B-19 11.73-acre Control Unit has Class I hazardous waste lying immediately above it. The separation liner located above the hazardous waste is designed for closure of the Class I hazardous waste in the landfill and the disposal of Class II/III designated and MSW over it. The separation liner consists of (from top to bottom): 2-foot soil operations layer; geocomposite drainage layer; 60-mil textured HDPE geomembrane liner; and a 2-foot low-permeability foundation layer with a hydraulic conductivity of less than or equal to 1 × 10-5 cm/sec. 36. The waste containment system for Landfill B-19 as described in Finding No. 34 exceeds the Title 27 prescriptive standards for Class II & III containment and the Section III containment system requirements of amended State Water Resolution No. 93-62. Landfill B-17 37. Class II/III Landfill B-17 is proposed for construction southwest of Landfill B-19 (see Attachment 2). The 62.1-acre landfill will be constructed in three phases (A, B, and C) and will have a total gross capacity of approximately 18.4 million cubic yards, including liner and final cover systems. 38. Landfill B-17 will be operated by the “dry tomb” method (no liquid additions). 39. The proposed containment system for Phases A, B, and C for Class II/III Landfill B-17 is provided in Table 2 as shown below: TABLE 2 WASTE DISCHARGE REQUIREMENTS ORDER NO.

The waste containment system for Landfill B-17 as described in Finding No. 39 meets or exceeds the Title 27 prescriptive standards for Class II and Class III containment. The JTD submitted for Landfill B-17 contains a demonstration indicating that the proposed geosynthetic clay liners (GCLs) are an engineered alternative that exceed the prescriptive clay liner requirements of Title 27. GCLs have previously been demonstrated to be an engineered alternative equivalent to the prescriptive clay liner requirements of Title 27. WASTE CLASSIFICATION 41. This Order will regulate the discharge of non-hazardous Class III MSW, and Class II designated solid waste, to Landfill B-17 and the Landfill B-19 Bioreactor and Control Unit, as defined in Title 27 CCR Section 20164. Non-hazardous solid waste includes MSW, as referred to in the Code of Federal Regulations, Title 40, (40 CFR), Part 258.2. This Order will also regulate the proposed addition of non-hazardous liquids into the bioreactor portion of Landfill B-19. These classified wastes may be discharged only in accordance with Title 27, CCR; Resolution No. 93-62 (as amended 21 July 2005); and 40 CFR, Part 258 as required by this Order. 42. The Discharger proposes to dispose of treated wood waste into the landfills. “Treated wood” means wood that has been treated with chemical preservatives registered pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. Sec. 136 and following). Treated wood waste is exempt from hazardous waste regulation under the amended federal Resource Conservation and Recovery Act (RCRA) of 1976, if it is disposed of in a municipal landfill that meets the disposal site classification requirements contained in the Porter-Cologne Water Quality Control Act, and the landfill also meets the requirements specified in Sections 25143.1.5 and 25150.7 of the Health and Safety Code. Section 25150.8 of the Health and Safety Code indicates that if the treated wood WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -9- waste is managed and disposed of in a solid waste landfill in the manner specified, it is considered to be non-hazardous waste. BIOREACTOR OPERATION 43. The bioreactor will be operated within 18.23-acres of Landfill B-19 Phase IA extending into a small wedge-shaped area within the northern portion of Phase IB of the landfill. It will be permitted as an RD&D project allowing the introduction of supplemental non- hazardous liquids in accordance with Section II.C. of State Water Board Resolution No. 93-62 (as amended 21 July 2005). The bioreactor liner exceeds the prescriptive containment system requirements stated in Section III. of the Resolution. The bioreactor has requirements in the Monitoring and Reporting Program of this Order specific to monitoring its operation. 44. The benefits of operating a bioreactor include applying liquids to the landfill, that would have to otherwise be disposed of in surface impoundments, to accelerate the waste decomposition process; more rapid decomposition, resulting in more rapid waste settlement, thereby increasing the disposal capacity of the landfill and ultimately resulting in the need for less landfills; also, more rapid decomposition causes more rapid gas generation, where the gas can be collected and used beneficially as an energy source. Environmental risks and potential impacts are reduced at closure since the waste mass of a landfill that has been operated as a bioreactor is stabilized and gas emissions are greatly reduced. 45. The bioreactor will be operated as an anaerobic bioreactor, with the addition of liquids at a rate of approximately 50 to 75 gallons per cubic yard of waste to bring the waste up to near the moisture-holding capacity (field capacity). It is anticipated that up to 170,000 gallons per day will be added to the waste, with trucks delivering liquid waste for direct application at the working face, to infiltration galleries, and to liquid storage tanks that are plumbed to a series of vertical injection wells. At the maximum rate of liquid addition, it is estimated that it will take approximately 3 ½ years to bring the waste mass to field capacity. 46. The leachate collection and removal system (LCRS) will minimize head buildup on the primary liner system. An automated pumping system will be installed consisting of a float activated primary LCRS sump pump. Fluid levels in the sump will be continuously monitored and recorded with an electronic digital readout system. The sump pump will be sized to remove the maximum expected leachate generation rate without excessive fluid head buildup on the primary liner. Leachate would be reintroduced into the unit or removed to the Class I surface impoundments, as needed. Design calculations indicate that the head buildup on the primary liner would be less than seven inches should the waste reach field capacity. WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -10- 47. LFG and volatile organic compound (VOC) emissions typically increase as liquids are added to MSW. Since the calculated VOC emission rate exceeds 50 Mg/yr for the “dry tomb” operation of Landfill B-19, the landfill is subject to the New Source Performance Standards gas collection and control requirements contained in the 40 CFR, Part 60, Subpart WWW. LFG CONTROL 48. Before operating the bioreactor, the Discharger will install a LFG collection and removal system for both the Landfill B-19 Bioreactor and Landfill B-19 Control Unit meeting both the Title 27 and federal standards. Installation will require the Discharger to obtain an Authority to Construct and a Permit to Operate from the San Joaquin Valley Unified Air Pollution Control District. The system has been designed to remove and flare 2,225 scfm (assuming 90% gas recovery efficiency at the peak gas generation rate) that is predicted to occur approximately three years after initiating liquid additions to the bioreactor. 49. In accordance with 40 CFR, Part 60, Subpart WWW, a LFG collection and removal system will be installed for Landfill B-17. Installation will require the Discharger to obtain an Authority to Construct and a Permit to Operate from the San Joaquin Valley Unified Air Pollution Control District. The system will be constructed to meet the Title 27 and federal standards. LANDFILL MONITORING LFG Monitoring 50. The Discharger has installed eleven gas probes (GP-1A, GP-2A, GP-3A, GP-3BC, GP-4A, GP-4BC, GP-5A, GP-5BC, GP-6A, GP-7A, and GP-8A) around the perimeter of Landfill B-19. Two gas probes (GP-4D & GP-5D) have been installed at the facility property boundary in accordance with Title 27, Sections 20923 and 20925. The probes and five on-site structures are monitored for methane gas in accordance with Title 27. 51. Eight gas probes will be installed at the property boundary for Landfill B-17 and monitored for methane gas in accordance with Title 27. 52. The Discharger will collect gas samples from the Landfill B-19 secondary LCRS riser pipe to monitor the performance of the LFG collection and removal system in accordance with the monitoring and reporting program. Unsaturated Zone Monitoring 53. The Discharger has conducted a field test demonstrating that the collection of soil-pore liquid samples with suction lysimeters or similar suction-based technology as a component of an active unsaturated zone monitoring system at the facility is not feasible WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -11- since soil suction values greatly exceed the pressure limits of these devices for collecting liquid samples. Therefore, the Discharger will use pan lysimeter collection systems installed below the low points of the landfill containment systems to collect liquids by gravity drainage. The pan lysimeters will serve as passive unsaturated zone monitoring systems for the landfills. 54. Landfill B-19 is equipped with 15-foot wide, 1-foot deep pan lysimeters installed below the axial low points of the WMU containment system that serve as an extended pan lysimeter. The trenches are lined with 80-mil HDPE geomembrane, packed with high transmissivity granular material, and terminate at unsaturated zone pan lysimeter collection sumps located below the secondary leachate collection sumps in each phase of the landfill. The Landfill B-19 Phase IA unsaturated zone pan lysimeter collection sump will serve as the unsaturated zone monitoring system for both the landfill bioreactor and the control unit. Fluids will be collected and analyzed from the sump in accordance with the Monitoring and Reporting Program. 55. Below the low point of each phase of Landfill B-17 (below each secondary LCRS sump), the Discharger will install gravel-filled pan lysimeter collection sumps that will serve as the unsaturated zone monitoring systems for the unit. Fluids will be collected and analyzed from the sumps in accordance with the Monitoring and Reporting Program. Groundwater Monitoring 56. VOCs are often the primary constituents detected in releases to groundwater from MSW landfills. Since VOC’s are not naturally occurring and thus have no background value, they are not amenable to the statistical procedures contained in Title 27 for determining the evidence of a release. 57. Sections 20415(e)(8) and (9) of Title 27 provide for the non-statistical evaluation of monitoring data that will provide the best assurance of the earliest possible detection of a release from a unit in accordance with Section 20415(b)(1)(B) 2. through 4. of Title 27. However, Title 27 does not specify a specific method for non-statistical evaluation of monitoring data. 58. The Regional Water Board may specify a non-statistical data analysis method pursuant to Section 20080(a)(1) of Title 27. Section 13360(a)(1) of the California Water Code (Water Code) allows the Regional Water Board to specify requirements to protect groundwater or surface waters from leakage from a solid waste site, including a method that provides the best assurance of determining the earliest possible detection of a release. 59. Due to significant geochemical spatial variability in the poor quality groundwater across the facility and the lack of contrast between the concentrations of inorganics in the leachate and the same naturally occurring inorganics in the groundwater, the statistical procedures specified in Section 20415(e) of Title 27 for detection monitoring have WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -12- proved to be ineffective in providing any assurance of detecting a release from any waste management unit. Therefore, in order to provide the best assurance of the earliest possible detection of a release of non-naturally occurring waste constituents from the landfills, this Order specifies a non-statistical method for evaluating the monitoring data using intrawell comparison as indicated in Section D.1. of the Monitoring and Reporting Program. 60. Groundwater monitoring wells K-69 and K-70 will provide detection monitoring for the Landfill B-19 Bioreactor and Control Units. 61. Groundwater monitoring well K-73 will provide detection monitoring for Landfill B-17 Phase A. Well K-72 will serve as a “gradient” well for measuring groundwater depths. The wells are shown on Attachment 2. Additional detection monitoring wells will be installed for the other proposed phases of Landfill B-17 prior to their construction. 62. Groundwater detection monitoring Wells K-69, K-70, K-73, and any other detection monitoring wells installed for the future phases of Landfill B-17 will be monitored for the VOC detection monitoring parameters at the frequency specified in the Monitoring and Reporting Program. 63. In accordance with Section 20420(g) of Title 27, groundwater detection monitoring Wells K-69, K-70, K-73, and any other detection monitoring wells installed for the future phases of Landfill B-17 will also be monitored for the Constituents of Concern (COCs) at 5-year intervals using intrawell statistical and non-statistical procedures as specified in the most recent edition of the Site-Specific Groundwater Monitoring Plan for the Landfill B-19 Bioreactor and Control Unit, and Landfill B-17. The plan is included by reference in the Monitoring and Reporting Program. LANDFILL CLOSURE 64. Closure and post-closure maintenance requirements for landfills are contained in Section 21090 of Title 27. The prescriptive standard for the final cover is contained in Section 21090(a) of Title 27. 65. Section 20080(b) of Title 27 allows the Regional Water Board to consider the approval of an engineered alternative to the prescriptive standard. In order to approve an engineered alternative in accordance with Section 20080(c)(1) and (2), the Discharger must demonstrate that the prescriptive design is unreasonably and unnecessarily burdensome and will cost substantially more than an alternative which will meet the criterion contained in Section 20080(b), or would be impractical and would not promote attainment of applicable performance standards. The Discharger must also demonstrate that the proposed engineered alternative cover system is consistent with the performance goals addressed by the particular prescriptive standard, and provides protection against WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -13- water quality impairment equivalent to the prescriptive standard in accordance with Section 20080(b)(2) of Title 27. 66. Section 13360(a)(1) of the Water Code allows the Regional Water Board to specify the design, type of construction, and/or particular manner in which compliance must be met in WDRs or orders for the discharge of waste at solid waste disposal facilities. 67. Information was submitted in the JTDs proposing the construction of an engineered alternative in lieu of the prescriptive cover design specified in Section 21090(a) of Title 27. The proposed engineered alternative is a 4-foot thick evapotranspirative (ET) cover consisting of fine sand with some clay or sandy clay having a low plasticity index. An ET cover design is engineered and constructed to absorb moisture during precipitation events and subsequently expel moisture by evaporation and transpiration. Preliminary water balance modeling using the UNSAT-H computer program indicate that the proposed ET cover is not likely to transmit moisture to the underlying waste. The performance of the ET cover system will be monitored in accordance with Closure Construction Specification G.4. 68. The Discharger has demonstrated that construction of a Title 27 prescriptive standard cover system would be unreasonably and unnecessarily burdensome when compared to the proposed engineered alternative design. Previous field studies conducted at the KHF during the early 1990s have shown that low permeability Title 27 prescriptive clay cover systems perform very poorly in the semi-arid climate at the facility. The systems developed extensive desiccation cracking within a 3-year period. 69. The proposed ET cover is less prone to desiccation cracking, is less susceptible to damage from differential settlement, and should result in lower post-closure maintenance costs when compared to the prescriptive low permeability clay cover system. The ET cover system is designed to meet the performance goals of Title 27 by isolating the waste from moisture, and by resulting in minimum maintenance during the post-closure period. 70. In order to monitor the performance of the ET cover systems, the Discharger is required to install gravel-filled pan lysimeter(s) beneath the final cover in the top deck area of the Landfill B-19 Bioreactor/Control Unit. POST-EARTHQUAKE INSPECTION AND RESPONSE PLAN 71. The Discharger will implement a Post-Earthquake Inspection and Response Plan as specified in the Monitoring and Reporting Program. An inspection will be conducted following an earthquake of Magnitude (Mw) 5.0 or greater within 25 miles of the facility or a Magnitude (Mw) 6.0 or greater earthquake within 50 miles of the facility. CEQA AND OTHER CONSIDERATIONS WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -14- 72. An Environmental Impact Report (EIR) for the construction and operation of Class I waste management units at the Kettleman Hills Facility was prepared and approved by the Kings County Planning Department in January 1986. Kings County adopted a Subsequent EIR (SEIR) for the proposed construction and operation of a Class II/III landfill within Landfill B-19 at the facility and filed a Notice of Determination on 16 December 1997. Kings County adopted an SEIR on 6 June 2005 for operation of the Landfill B-19 Bioreactor and filed a Notice of Determination on 7 June 2005. Kings County adopted an SEIR on 30 May 2006 for the construction and operation of new Class II/III Landfill B-17 and filed a Notice of Determination on 31 May 2006. The SEIRs were adopted and noticed in accordance with the California Environmental Quality Act (CEQA) (Public Resources Code, Section 21000 et seq.) and CEQA guidelines (14 CCR, Section 15000 et seq.). 73. The Regional Water Board has considered the SEIRs and has reached its own conclusions regarding the operation of the Landfill B-19 Bioreactor and the construction and operation of new Class II/III Landfill B-17 at the facility. Compliance with these WDRs will prevent and mitigate any significant adverse impacts to water quality from facility operations. 74. This order implements: a. The Water Quality Control Plan for the Tulare Lake Basin, 2nd Edition (1995); b. The prescriptive standards and performance goals of Chapters 1 through 7, Subdivision 1, Division 2, Title 27, of the California Code of Regulations, effective 18 July 1997, and subsequent revisions; c. The prescriptive standards and performance criteria of RCRA Subtitle D, Part 258; and d. State Water Board Resolution No. 93-62, Policy for Regulation of Discharges of Municipal Solid Waste, adopted 17 June 1993 and amended 21 July 2005. 75. Section 13267(b)(1) of the Water Code provides that: “In conducting an investigation specified in subdivision (a), the regional board may require that any person who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge waste within its region, or any citizen or domiciliary, or political agency or entity of this state who has discharged, discharges, or is suspected of having discharged or discharging, or who proposes to discharge, waste outside of its region that could affect the quality of waters within its region shall furnish, under penalty of perjury, technical or monitoring program reports which the regional board requires. The burden, including costs, of these reports shall bear a reasonable relationship to the need for the report and the benefits to be obtained from the reports. In requiring those reports, the regional board shall provide the person with a written explanation with regard to the WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -15- need for the reports, and shall identify the evidence that supports requiring that person to provide the reports.” The reports required in the Monitoring and Reporting Program, that is part of this Order, are necessary to ensure compliance with the WDRs. 76. A Solid Waste Facility Permit (SWFP) will be issued by the Kings County Department of Public Health (the LEA) after concurrence from the California Integrated Waste Management Board. The SWFP will among other things, allow a portion of Landfill B-19 to be operated as a bioreactor, allow an increase in the daily tonnage of Class II/III wastes received at the facility landfills from 1,400 tpd to 2,000 tpd, and allow an increase in daily hours of operation to include Saturday’s from 8:00 a.m. to 6:00 p.m. A second SWFP will be issued to allow the operation of new Landfill B-17. 77. Since the operation of proposed Landfill B-17 will require an additional 8.5 acres of land beyond the current Conditional Use Permit (CUP) boundary, the Kings County Planning Commission approved a new CUP (No. 04-01) on 30 May 2006, to increase the existing operations area at the facility and to allow the increase in daily tonnage and operating hours. PROCEDURAL REQUIREMENTS 78. All local agencies with jurisdiction to regulate land use, solid waste disposal, air pollution, and to protect public health have approved the use of this site for the discharges of waste to land as stated herein. 79. The Regional Water Board notified the Discharger and interested agencies and persons of its intent to prescribe WDRs for this discharge, and has provided them with an opportunity for a public hearing and an opportunity to submit their written views and recommendations. 80. The Regional Water Board, in a public meeting, heard and considered all comments pertaining to the discharge. 81. Any person affected by this action of this Regional Water Board may petition the State Water Board to review the action in accordance with Sections 2050 through 2068, Title 23, California Code of Regulations. The petition must be received by the State Water Resources Control Board, Office of Chief Counsel, P.O. Box 100, Sacramento, California 95812, within 30 days of the date of issuance of this Order. Copies of the laws and regulations applicable to the filing of a petition are available on the Internet at http://www.waterboards.ca.gov/water_laws/index.html and will be provided on request. IT IS HEREBY ORDERED, pursuant to Sections 13263 and 13267 of the Water Code, that the specifications and provisions contained in Order No. 98-058 that apply to Landfill B-19 Class II/III designated/municipal solid waste operations, monitoring, and closure/post-closure are WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -16- superseded by this Order and that Chemical Waste Management, Inc., its agents, successors, and assigns, in order to meet the provisions contained in Division 7 of the Water Code and the regulations adopted thereunder, shall comply with the following: A. PROHIBITIONS The following discharges are prohibited: 1. The discharge of solid or liquid waste or leachate to surface waters, surface water drainage courses, groundwater, and natural geologic materials adjacent to the WMUs. 2. The discharge of hazardous waste to non-hazardous WMUs, except for hazardous waste that has been granted a variance from hazardous waste management requirements pursuant to Section 13173 of the California Water Code. Hazardous waste is defined in Section 2601 (Technical Definitions) of Title 23, California Code of Regulations. 3. The discharge of waste to closed WMUs. 4. Free liquids, except for leachate from a landfill LCRS or liquids from lab-packs, waste containing free liquids or containerized free liquids, to the Landfill B-19 Control Unit and to Landfill B-17. 5. The addition of liquids to the Landfill B-19 Bioreactor without U.S. EPA approval of amended State Water Board Resolution No. 93-62. 6. The discharge of non-hazardous liquids to the Landfill B-19 Bioreactor Unit three years beyond the date of U.S. EPA approval of amended Resolution No. 93-62, unless this Order is revised at the end of this three year period allowing for the continued addition of liquids to the bioreactor for another three year period. The WDRs can be revised at the end of each three year period, up to but not to exceed a total of 12 years [this Order (3 years) plus three revisions (9 years)]. The start date of the Bioreactor will be the date of the first liquid addition, which can only occur after all necessary permits have been obtained. The Discharger shall provide written notification of that start date to the Regional Water Board. 7. Radioactive materials that require special placards because they exceed 2,000 picocuries/gram of activity as referenced in 49 CFR 173.403(y). 8.

Wastes that have the potential to reduce or impair the integrity of containment structures or which, if commingled with other wastes in the WMU, could produce violent reaction, heat or pressure, fire or explosion, toxic by-products, or reaction products which in turn: a. require a higher level of containment than provided by the WMU; b. are ‘restricted hazardous wastes’; or b. impair the integrity of containment structures. B. FACILITY DISCHARGE SPECIFICATIONS 1. Non-hazardous wastes shall be discharged only into the landfills specifically designed for their containment, as described in this Order and Title 27. 2. The Discharger shall remove to an appropriate WMU any wastes that are discharged at this site in violation of this Order, or shall otherwise respond to such discharges in accordance with an approved contingency or remedial plan. 3. The treatment, storage, biodegradation, or disposal of wastes shall not cause pollution or a nuisance as defined in Section 13050 of the California Water Code. 4. “Treated wood” wastes may be discharged to a WMU equipped with a composite liner and a leachate collection and removal system and shall be handled in accordance with Sections 25143.1.5 and 25150.7 of the California Health and Safety Code. “Treated wood” means wood that has been treated with chemical preservatives registered pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. Sec. 136 and following). The preservatives protect the wood from damage and decay caused by insects, microorganisms, fungi, and other environmental conditions. This may include, but may not be limited to, waste wood that has been treated with chromated copper arsenate (CCA), pentachlorophenol, creosote, acid copper chromate (ACC), ammoniacal copper arsenate (ACA), ammoniacal copper zinc arsenate (ACZA), or chromated zinc chloride (CZC). 5. Treated wood must be managed to ensure consistency with Sections 25143.1.5 and 25150.7 of the Health and Safety Code. If a verified release is detected from the waste management unit where treated wood is disposed of, the disposal of treated wood shall be terminated at the unit with the verified release until corrective action ceases the release.

Discharge Specification B.4 and B.5 apply only to treated wood waste that is hazardous due solely to the presence of preservatives in the wood, and is not subject to hazardous waste regulations under the federal act. 7. When triggered by the requirements of 40 CFR, Part 60, Subpart WWW, methane and other landfill gases, including VOCs, generated at Landfill B-17 and at Landfill B-19 shall be collected and flared, or converted to energy via a cogeneration facility, or utilized via other viable options, to prevent any potential danger to human health, nuisance conditions, impairment of the beneficial uses of surface water or groundwater due to migration through the vadose (unsaturated) zone, or migration into on or off-site structures. 8. Landfill gas collection and control systems shall be designed, constructed, operated, and monitored in conformance with 40 CFR, Part 60, Subpart WWW. 9. Gas condensate that is not flared can be recirculated back into the Landfill B-19 bioreactor and Landfill B-17 provided it is non-hazardous and provided it will not have an adverse impact on the waste biodegradation process. 10. Any liquid supplement can be added to the Landfill B-19 Bioreactor provided it is non-hazardous and provided it will enhance biodegradation of the waste. 11. Pursuant to Title 27, Sections 20200(d) and 20340(g), the amount of leachate and/or supplemental liquids injected and infiltrated into the Landfill B-19 Bioreactor shall not exceed the “moisture holding capacity” of the waste mass, as defined in Title 27. The generation of leachate in the LCRS during the liquid additions shall not be construed as violating this specification, provided that leachate continues to be absorbed into the waste mass in significant quantities and that the rate of liquid addition is adjusted as practicable to minimize excessive leachate production. The moisture holding capacity, or “field capacity” of the bioreactor, shall be construed as the point where, under steady-state conditions, leachate is no longer being absorbed into the waste mass in significant quantities, as evidenced by the rate of leachate production being approximately equal to the liquid addition rate. Prohibition A.8 in this Order shall apply should this condition develop. 12. If a build up of hydraulic head greater than one foot occurs on the primary liner system as indicated by measurement of the fluid level in the magnehelic line (or other suitable device) in any landfill primary LCRS sump regulated by this Order, the Discharger shall immediately notify the Regional Water Board and provide a written notification within seven days. The written notification shall include a timetable for implementing corrective action measures necessary to reduce leachate production. WASTE DISCHARGE REQUIREMENTS ORDER NO.

R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -23- 5. Gas collection and control systems shall be monitored in accordance with the Monitoring and Reporting Program. F. DETECTION MONITORING SPECIFICATIONS 1. The unsaturated zone detection monitoring system for the Landfill B-19 Bioreactor and Control Unit shall include the Landfill B-19 Phase IA vadose zone collection sump (pan lysimeter) for the collection of liquid samples. 2. The unsaturated zone detection monitoring system for the Landfill B-17 shall include the pan lysimeters installed under the secondary LCRS collection sumps for the collection of liquid samples. 3. The Discharger shall provide notification at least 10 days prior to installing any groundwater monitoring wells, gas probes, and pan lysimeters. 4. The groundwater detection monitoring system shall consist of detection monitoring Wells K-69 and K-70 for the Landfill B-19 Bioreactor and Control Units, and detection monitoring Well K-73 and gradient Well K-72 for Landfill B-17 Phase A as shown in Attachment 2 of this Order. 5. Additional groundwater detection monitoring wells shall be installed for the other two phases of proposed Landfill B-17 (Phases B & C). Four quarters of groundwater analytical data shall be obtained from each of these wells prior to waste being discharged to the associated/new phase of the landfill in accordance with Title 27, Section 20415(e)(6). 6. Both unsaturated zone and groundwater detection monitoring shall be conducted in accordance with the Monitoring and Reporting Program. 7. For each monitoring event, the Discharger shall determine whether the landfill is in compliance with the Water Quality Protection Standard using procedures specified in the Monitoring and Reporting Program. 8. The concentrations of the constituents of concern in groundwater passing the Point of Compliance shall not exceed the concentration limits established pursuant to the Monitoring and Reporting Program. 9. Groundwater samples shall be collected from the monitoring points leaving a sufficient amount of time to satisfy the data analysis requirements for the reporting period. The pre-sample purging method and field parameter measurements shall ensure that representative groundwater samples are collected for each sampling event. Specific methods of collection and analysis must be WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -24- identified. Sample collection, storage, and analysis shall be performed according to the most recent version of U.S. EPA Methods, such as the latest editions, as applicable, of: (1) Methods for the Analysis of Organics in Water and Wastewater (U.S. EPA 600 Series), (2) Test Methods for Evaluating Solid Waste (SW-846, latest edition), and (3) Methods for Chemical Analysis of Water and Waters (U.S. EPA 600/4-79-020), and in accordance with the most recently approved edition of the Site-Specific Groundwater Monitoring Plan. 10. The methods of analysis and the detection limits used must be appropriate for the expected concentrations. For the monitoring of any constituent or parameter that is found in concentrations which produce more than 90% non-numerical determinations (i.e., “trace or “ND”) in the data, the analytical method having the lowest method detection limit (MDL) shall be selected from among those methods which would provide valid results considering potential matrix effects or interferences. 11. “Trace” results are analytical results that fall between the MDL and practical quantitation limit (PQL) and shall be “J” flagged as such, including the estimated MDL and PQL values for that analytical run. 12. MDLs and PQLs shall be derived by the laboratory for each analytical procedure, according to the State of California laboratory accreditation procedures. These MDLs and PQLs shall reflect the detection and quantitation capabilities of the specific analytical procedure and equipment used by the lab, rather than simply being quoted for U.S. EPA analytical method manuals. In relatively interference-free water, laboratory-derived MDLs and PQLs are expected to closely agree with published U.S. EPA MDLs and PQLs. 13. If the laboratory suspects that, due to a change in matrix or other effects, the true detection limit or quantitation limit for a particular run differs significantly from the laboratory-derived MDL/PQL values, the results shall be flagged accordingly, along with estimates of the detection limit and quantitation limit actually achieved. The MDL shall always be calculated such that it represents the lowest achievable concentration associated with a 99% reliability of a nonzero result. The PQL shall always be calculated such that it represents the lowest constituent concentration at which a numerical value can be assigned with reasonable certainty that it represents the constituent’s actual concentration in the sample. Normally, PQLs should be set equal to the concentration of the lowest standard used to calibrate the analytical procedure. 14. All Quality Assurance/Quality Control (QA/QC) data shall be reported, along with the sample results to which they apply, including the method, equipment, analytical detection and quantitation limits, the percent recovery, an explanation WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -25- for any recovery that falls outside the QC limits, the results of equipment and method blanks, the results of spiked and surrogate samples, the frequency of quality control analysis, and the name and qualifications of the person(s) performing the analyses. Sample results shall be reported unadjusted for blank results or spike recoveries. In cases where contaminants are detected in QA/QC samples (i.e., field, trip, or lab blanks), the accompanying samples results shall be appropriately flagged. 15. During 5-year constituent of concern sampling events, unknown chromatographic peaks shall be reported, flagged, and tracked for potential comparison to subsequent peaks that may be observed in future sampling events. When unknown peaks are encountered, second column or second method confirmation procedures may be performed in an attempt to identify and more accurately quantify the unknown analyte. 16. For groundwater detection monitoring at the facility, the Discharger shall use the non-statistical data analysis procedure as specified in the Monitoring and Reporting Program. 17. The statistical method shall account for data below the PQL with a statistical procedure that is protective of water quality. Any PQL concentration used in statistical calculations pursuant to Title 27 CCR Section 20415(e)(7) shall be derived as specified in Detection Monitoring Specification F.13 of this Order. Any laboratory used by the Discharger shall consider the PQL concentrations listed in Appendix IX to Chapter 14 of Division 4.5 of Title 22, CCR, as a reference for comparing their PQL concentrations in accordance with Detection Monitoring Specification No. F.12 of this Order. For any given COC monitored, trace results shall be identified and used in an appropriate statistical method. For a statistical method that is compatible with the proportion of trace and non-detect values in the data set, the Discharger can use the laboratory’s concentration estimates in the trace range (if available) for statistical analysis, in order to increase the statistical power by decreasing the number of “ties.” G. CLOSURE CONSTRUCTION SPECIFICATIONS & POST-CLOSURE 1. Prior to beginning construction on any landfill cover system, a Closure/Post- Closure Maintenance Plan shall be submitted for review. The plan shall include, but not be limited to, the engineered design plans and construction drawings for the WMU cap and a construction quality assurance (CQA) plan to verify that construction specifications will be met. The CQA plan monitoring and testing shall be performed by an independent third party and shall be supervised by a registered civil engineer or certified engineering geologist who is designated as the CQA officer. The Closure Plan shall be prepared by a registered civil engineer WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III LANDFILL B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY -26- or certified engineering geologist and shall be submitted for review and approval prior to commencing construction. 2. The final cover systems for the Landfill B-19 Bioreactor/Control Unit and Landfill B-17 shall be constructed with an engineered alternative design known as an evapotranspirative (ET) or monolithic soil cover design. The cover shall, at a minimum, consist of a three-foot thick vegetated soil layer placed over an existing interim cover soil of one-foot thickness, having the same consistency and characteristics as the three foot layer (combined minimum thickness equal to 4 feet). The soil material used shall be a low plasticity index fine sand with some clay or sandy clay that is not susceptible to desiccation cracking and excessive soil erosion. The soil layer shall be placed in a manner ensuring its structural integrity and ability to promote vegetative growth. 3. A Final Closure Construction Certification Report shall be submitted for each WMU cover system constructed. As-built plans and final closure cover drawings and the CQA testing results shall be included in the closure certification report. The CQA testing shall include a written summary of the CQA program, all test results, analyses, and copies of the inspector’s original field notes. The closure certification report shall contain sufficient information and test results to certify that construction was completed in accordance with the approved Closure/Post-Closure Maintenance Plan. The report shall be prepared by a registered civil engineer or certified engineering geologist and shall be submitted for review and approval. 4. Since Landfill B-19 will be closed several years before Landfill B-17, as part of the construction of the ET cover system for the Landfill B-19 Bioreactor and Control Unit, one or more pan lysimeters shall be constructed on the upper deck of the landfill beneath the ET cover to monitor its performance. The final ET cover system for Landfill B-17 shall be based upon the performance of the Landfill B-19 final ET cover system and any final adjustments made to the system to improve its ability to preclude moisture flow-through to the underlying waste. No pan lysimeters shall be required for the Landfill B-17 ET cover system provided a Landfill B-19 ET cover system performance report is submitted demonstrating that the system performs satisfactorily. 5. Proposed changes to ET cover system design can be made so long as it is demonstrated that the changes will provide an equal or greater ability to isolate moisture from the waste and provided the design change is submitted and approved.

CREEDON, Executive Officer, do hereby certify the foregoing is a full, true, and correct copy of an Order adopted by the California Regional Water Quality Control Board, Central Valley Region, on 27 October 2006. ____________________________________ PAMELA C. CREEDON, Executive Officer JKD/kes:10/27/06 INFORMATION SHEET ORDER NO. R5-2006-0122 CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY Chemical Waste Management, Inc. (CWMI) owns and operates the 1,600-acre Kettleman Hills Facility, of which 499 acres has a Conditional Use Permit as well as various other permits, including a Hazardous Waste Facility Permit, Waste Discharge Requirements (WDRs), and a Solid Waste Facility Permit, for accepting Class I liquid and solid hazardous wastes, Class II/III designated liquid and solid wastes, and municipal solid waste. The facility has been used as a land disposal site for liquid and solid hazardous wastes since at least 1975, and for designated/municipal solid wastes since 1998. It is located approximately 1 mile north of State Highway 41 and 3.5 miles southwest of Kettleman City. WDRs Order No. 98-058 currently implements Title 22, Title 23, and Title 27 of the California Code of Regulations, regulating the disposal of hazardous waste and the disposal of designated/municipal solid waste at the facility. The new WDRs would supersede implementation of the Title 22 and Title 23 hazardous waste regulations, and will implement only the Title 27 non-hazardous waste regulations for permitting the addition of supplemental liquids to a portion of Class II/III Landfill B-19 (the 18.23-acre Bioreactor Unit) as an RD&D project in accordance with amended State Water Resources Control Board Resolution No. 93-62, the operation of a portion of Class II/III Landfill B-19 as a Control Unit (11.73-acres), the construction and operation of new Class II/III designated and municipal solid waste Landfill B-17 (62.1-acres), and the closure of these units. CWMI is a wholly owned subsidiary of Waste Management, Inc. of Texas, a company that has considerable experience in operating bioreactor units. Waste Management, Inc. is currently operating ten bioreactor projects in both the United States and Canada. The benefits from operating a landfill as a bioreactor, rather than the current “dry tomb” practice, are: 1) Liquids, such as leachate and wastewater, are added to the bioreactor waste to speed up the waste decomposition process. This is considered to be a beneficial use of these liquids, which would have to be otherwise disposed of in surface impoundments. 2) More rapid waste decomposition resulting in more rapid waste settlement and more rapid gas generation. The waste settlement increases the landfill air space by 15-40%, providing an increase in the waste disposal capacity of the unit. More rapid gas generation from a bioreactor unit reduces the potential environmental impacts vs. the long-term impacts from gas emissions from a “dry tomb” landfill. Gas can potentially be recovered and used as an energy source to generate electricity or to power a fleet of trucks or buses designed to run on methane. 3) The more rapid waste settlement provides an increase in disposal capacity with a bioreactor, resulting in the need for less landfills. 4) A stabilized waste mass with lower gas emissions at closure results in lower post-closure maintenance costs and less environmental risks/impacts. ORDER NO. R5-2006-0122 -2- CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY Landfill B-19 is well suited for conversion to a bioreactor, having a double composite bottom liner system that exceeds the Title 27 prescriptive standards for Class III containment. The Kettleman Hills Facility is situated in an environmentally conducive area for operating a bioreactor unit and constructing new Class II/III landfills since there are no surface water bodies near the facility (nearest surface water is the California Aqueduct, 3.5 miles to the east), groundwater is relatively deep and of poor quality and is isolated from useable groundwater in both the Kettleman Plain and the San Joaquin Valley, and the facility is physically separated from any populated areas by several rolling hills and intervening gullies. The groundwater under the facility is not a municipal or domestic supply (MUN) and has very limited beneficial uses. On-site groundwater detection monitoring wells have very low yields (< 5 gpm) and are typically pumped dry in less than 30 minutes. The nearest off-site water supply wells with relatively good quality groundwater lie about 1.5 miles west of the facility, in the Kettleman Plain. The climate around the facility is semi-arid, with annual average precipitation at 6.61 inches per year. The facility is not located within a 100-year flood plain and the landfills are not located in areas subject to rapid geologic change. A portion of Landfill B-19 will be operated as a conventional “dry tomb” Control Unit, where no liquid waste will be added. The Landfill B-19 Bioreactor Unit will be operated immediately adjacent to the Landfill B-19 Control Unit, where the operation and performance of the two units can be compared in the same environmental setting. The new unit, Landfill B-17, will be constructed in three phases and will be operated as a conventional “dry tomb” unit. The landfill will have a double composite base liner system that meets or exceeds the required Title 27 prescriptive standards for Class III containment. The unit will have an 18.4 million cubic yard capacity (including final cover and liner materials). Both the Landfill B-19 Bioreactor and Control Unit have, and Landfill B-17 has or will have, groundwater detection monitoring systems to detect for the earliest possible evidence of a release from the units. The monitoring will be conducted semi-annually, utilizing monitoring parameters that will provide reliable evidence of the detection of a release. CWMI is proposing to close the landfills with evapotranspirative (ET) cover material as an engineered alternative to the Title 27 prescriptive standard. Field tests conducted at the facility by CWMI have shown that the low permeability Title 27 prescriptive clay cover systems perform very poorly in semi- arid climates such as exist at the Kettleman Hills Facility. The ET cover system would consist of a 4- foot thick layer of fine sandy material with some clay and a low plasticity index, with a vegetative cover. An ET cover is designed to absorb moisture during precipitation events and to evaporate and transpirate moisture between precipitation events and after the rainy season before it permeates the entire cover thickness. Preliminary results indicate that the proposed ET cover will prevent stormwater from percolating through the bottom of the cover system. ORDER NO. R5-2006-0122 -3- CHEMICAL WASTE MANAGEMENT, INC. CLASS II/III B-19 BIOREACTOR AND CONTROL UNIT CLASS II/III LANDFILL B-17 KETTLEMAN HILLS FACILITY KINGS COUNTY Regional Water Board staff reviewed and commented on the draft Subsequent Environmental Impact Reports (SEIRs) for both the Landfill B-19 Bioreactor and new Class II/III Landfill B-17, and comments were incorporated into the final SEIRs. Kings County, acting as the lead agency, adopted the final SEIRs and filed Notices of Determination on 6 June 2005 and 30 May 2006, respectively. The SEIRs were adopted and noticed in accordance with the California Environmental Quality Act (CEQA) (Public Resources Code, Section 21000 et seq.) and CEQA guidelines (14 CCR, Section 15000 et seq.).

Kettleman Hills Facility 35252 Old Skyline Road Kettleman City, CA 93239 Dear Mr. Henry, REGION IX 75 Hawthorne Street San Francisco, CA 94105 RE: Determination and Clarification of Acceptability under the CERCLA Off-Site Rule ("OSR") for Receiving Units at Chemical Waste Management, Inc., Kettleman Hills Facility Dear Mr. Henry; This purpose of the letter is to respond to your request for approval to receive CERCLA waste at Unit B-17, a municipal solid waste landfill, and to clarify the CERCLA OSR approval status of other units located at Chemical Waste Management, Inc. Kettleman Hills Facility (CAT000646117). The U.S. Environmental Protection Agency (EPA), Region 9 has made an affirmative determination regarding the acceptability status of Unit B-17 Phases A, Band C. As of the date of this letter, these units may accept CERCLA waste generated as a result of a CERCLA remedial or removal action ·provided that the wastes received are managed in accordance with all applicable permit conditions pertaining to these units. At this time we would like to clarify the acceptability status of other units at Chemical Waste Management, Inc. Kettleman Hills Facility: • Active and permitted units in existence prior to the effective date (September 16, 1993) of 40 CFR Part 300.440 are considered as approved to receive CERCLA waste. •On March 3, 2000, Unit B-19, a Class II/III solid waste disposal unit, was approved to receive solid CERCLA waste. • Unit B-18 Phases I and II and B-18 Phase ill (once permitted) are approved to receive CERCLA waste On September 16, 1993, EPA amended the National Oil and Hazardous Substances Pollution Contingency Plan (NCP), 40 CFR Part 300, by adding Section 300.440, now known as the Off-Site Rule (''Rule"). The Rule codifies the requirements contained in Section 121(d)(3) of CERCLA, 42 U.S.C. §9621 (d)(3), and incorporated many provisions ofEPA's former Off-site Policy. The Rule established criteria and procedure for determining whether facilities are acceptable for the receipt of CERCLA waste. The Rule requires that prior to a facilities initial receipt of CERCLA waste, EPA must determine that there are no relevant violations or releases at the facility. Should any new information affecting this determination (approval of B-17 Phases A, B, and C) as well as all receiving units at Chemical Waste Management, Inc. Kettleman Hills Facility be obtained in the future, EPA reserves the right to re-evaluate the acceptability of Chemical Waste Management, Inc. Kettleman Hills Facility to receive CERCLA waste in accordance with the Rule. If you have any questions concerning this matter, please contact Kandice Bellamy, Region 9's CERCLAOff-Site Rule Coordinator at (415) 972-3304.

To recap, I am newly assigned to the City of San Luis Obispo, Cultural Arts District Parking Structure project and was looking to get up to speed with Charter’s involvement in the project or if any requests for service disconnection have been made yet? I have four sites (610 Monterey St, 614 Monterey St, 633A 61 Palm St, and 633B Palm St) that are scheduled for demolition, and I need to verify that there are no connections to the residences or property and if so, have them removed. Here ae my questions. 1. Have any requests been made to Charter to remove services at the above addresses? 2. Is there a process to get on Charters schedule? 3. What timeframe are we looking at? 4. Is there anything else you might need from me (the City) to proceed?

Based on our discussions with and a site plan provided by the client (WATRY 2019), the proposed parking structure will consist of five levels; it will provide approximately 400 parking stalls and have a lowest level slab-on-grade finish floor elevation of approximately 189.3 feet (Elev. 189.3). The proposed structure will be constructed of reinforced concrete and will have a rectangular footprint that will occupy roughly the northern two-thirds of the site. Vehicular access to the garage will be from both Palm Street and Nipomo Street. Based on the architectural plan set prepared by Bryce Engstrom Architect (undated), the proposed theatre will consist of two to three stories and a rooftop deck that will be supported by slabs-on-grade at several finish floor elevations (Elevs. 189.4, 195.4 and 201.0). The proposed theatre will likely be of steel-frame and/or CMU construction and will occupy roughly the southern third of the site. Additional site improvements will consist of retaining walls up to 15 feet in height, exterior pedestrian flatwork, trash enclosures, landscaping, and Low Impact Development (LID) features that may include buried retention systems and/or bioswales. The parking structure and the theatre will be separate structures; however, an elevated walkway may be provided to connect the second and/or third floors. Dead plus live column loads provided by the client for the parking structure ranged from 125 kips for light exterior supports to 1,330 kips for girder supports. Dead plus live loads for the theatre were not available but were anticipated to be on the order of 250 kips. Cuts up to 16 feet from existing grades will be required to achieve planned finish grades. The new structures will be served by the existing municipal utility systems. The approximate site coordinates of latitude 35.2796N and longitude 120.6664W were obtained from the Google Earth Website (Google Earth 2019) and were taken at the approximate location shown on Figure 1 – Site Vicinity Map. The site is bordered by Palm Street to the north, Monterey Street to the south, Nipomo Street to the west, and residential and commercial developments to the east (from Project North). Existing site improvements consist of an asphalt concrete (AC) parking lot that occupies most of the site, with single-family residences located at the northeast and southwest corners. The remainder of the site consists of lands caped areas that include mature trees and shrubs. The site slopes to the northwest with surface elevations of 205 feet at the southeast corner to 189 at the northwest corner. The locations and disposition of existing utilities on the site are unknown. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 2 1912-016.SER.REV2 2.0 SCOPE OF SERVICES The authorized scope of work included review of the previous report prepared by this firm (ESP 2011), which included subsurface exploration data from this firm and from Kleinfelder (2005), a general site reconnaissance, field exploration, geotechnical and corrosivity (subcontracted to HDR, Inc.) laboratory testing, geotechnical analysis of the data gathered, and preparation of this report. The results of LID infiltration testing are also included. The analysis and subsequent recommendations were based on the findings from our field and laboratory testing, review of previous exploration data, the proposed development described herein, and our experience with similar projects. This report and recommendations are intended to comply with the considerations of Sections 1803.1 through 1803.6, J104.3 and J104.4, as applicable, of the 2019 California Building Code (CBC) and common geotechnical engineering practice in this area under similar conditions at this time. The test procedures were accomplished in general conformance with the standards noted, as modified by common geotechnical engineering practice in this area under similar conditions at this time. Preliminary geotechnical engineering recommendations for site preparation, below grade excavations, grading, utilities, foundations, interior slabs-on-grade and exterior pedestrian flatwork, retaining walls, vehicle PCC pavements, drainage and maintenance, and observation and testing are presented to guide the development of project plans and specifications. Application beyond this intent is strictly at the user’s risk. As there may be additional geotechnical issues, this firm can be retained to provide consultation as the design progresses, and to review project plans as they near completion to assist in verifying that pertinent geotechnical issues have been addressed and to aid in conformance with the intent of this report. This report does not address issues in the domain of contractors such as, but not limited to, site safety, loss of volume due to stripping of the site, shrinkage of soils during compaction, excavatability, dewatering, temporary slope angles, construction means and methods, etc. Analyses of the soil for radioisotopes, asbestos (either naturally occurring or in man-made products), lead or mold potential, hydrocarbons, or chemical properties is beyond the scope of this report. Ancillary features such as flag or light poles, temporary access roads, and non- structural fills are not within our scope and are also not addressed. Design o f LID features such as retention basins, bio swales, or other improvements is also beyond our scope.

The criteria presented in this report are considered preliminary until such time as any peer review or review by any jurisdiction has been completed, conditions have been observed by the geotechnical engineer in the field during construction, and the recommendations have been verified as appropriate, or modified by the geotechnical engineer in writing. 3.0 FIELD INVESTIGATIONS Eleven exploratory borings were drilled at the site on September 3 through 6, 2019. The borings were drilled with a truck-mounted Mobile Drill Model B-53 rig and a track-mounted CME-55 rig. The B-53 rig was equipped with a 6-inch outside diameter hollow stem auger. The CME-55 rig used a combination of 6-inch outside diameter solid stem auger during drilling in soil and HQ size rock cores using a triple tube wire-line and diamond/PDC impregnated bit system during coring within the underlying bedrock. Both drill rigs were equipped with an automatic hammer for soil sampling. The borings were drilled or cored to depths that ranged from approximately 4 to 63 feet below the existing ground surface (bgs). Three of the 11 borings (designated A, B and C) were converted to LID infiltration test holes (see Section 5.0); these borings were drilled to depths that ranged from approximately 4 to 13.5 feet bgs. All of the remaining eight borings met practical refusal. As the borings were drilled, soil samples were obtained using a 3-inch outside diameter ring-lined barrel sampler (ASTM D 3550-17 with shoe similar to ASTM D 2937-17). Standard Penetration Tests (SPT) (ASTM D 1586-11) using a 2-inch outside diameter sampler were also performed at selected depths in the borings and b ag samples were obtained from the auger cuttings. Rock cores were retrieved in accordance with ISRM and ASTM guidelines and placed into wax impregnated boxes for transport and storage in accordance with USBR guidelines. Soils encountered in Borings 1 through 8 were categorized and logged in general accordance with the Unified Soil Classification System and ASTM D 2488-17. Rock cores recovered were logged in general accordance with ASTM D 2113-14, Standard Practice for Rock Core Drilling and Sampling of Rock for Site Investigations. Copies of the borings logs and a boring log legend are included in Appendix A. In reviewing the boring logs and legend, the reader should recognize that the legend is intended as a guideline only, and there are a number of conditions that may influence the characteristics observed during drilling. These include, but are not limited to, the presence of Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 4 1912-016.SER.REV2 cobbles or boulders, cementation, variations in soil moisture, presence of groundwater, and other factors. It should also be noted that the descriptions of bedrock must span a much wider range of density and strength characteristics than soil and are relative to other bedrock strata. For example, fractured and weathered bedrock may be described as “soft,” yet it will be considerably harder than almost any type of soil. Conversely, a clay soil may be described as “hard,” however it will not be nearly as hard as even “soft” bedrock such as the graywacke encountered on this site. Consequently, the logger must exercise judgment in interpreting the subsurface characteristics, possibly resulting in soil and bedrock descriptions that vary somewhat from the legend. Additional borings were performed by Kleinfelder and this firm for investigations in 2005 and 2011, respectively. The approximate locations of all borings are shown on Figure 2 – Exploration Location Map in Appendix A. 4.0 LABORATORY ANALYSIS Selected soil samples were tested in our laboratory for bulk density (ASTM D 2937-17, modified for ring liners) and/or moisture content (ASTM D 2216-10), expansion index (ASTM D 4829-11), maximum density and optimum moisture content (ASTM D 1557-12), cohesion and angle of shearing resistance (ASTM D 3080/3080M-11, for both in-situ density and recompacted to 90 percent of maximum dry density, and modified for consolidated, undrained conditions), grain size distribution by sieve analysis (ASTM D 1140-17), plasticity index (ASTM D 4318-17), consolidation (ASTM D 2435/D 2435M-11) and R-value (ASTM D 2844/D2844M-13). Selected rock core samples were tested in our laboratory for compressive strength (ASTM D 7012). Unconsolidated undrained triaxial shear strength testing (ASTM D 2850) was subcontracted to Cooper Testing Labs in Palo Alto, California. The results of the laboratory tests for the current investigation, as well as the results from the previous investigations, are presented in Appendix B. 5.0 LID INFILTRATION TESTING After drilling was completed, a 2-inch diameter perforated pipe was installed in each of the three infiltration test borings and the annular spaces around the pipes were filled with gravel. Infiltration testing was performed in general accordance with the methods developed by this firm in cooperation with the Central Coast Low Impact Development Initiative (ESP 2013). Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 5 1912-016.SER.REV2 Initially, testing consisted of introducing water into each of the test borings to just below existing grade. This water level was then maintained at constant head for 30 minutes. After the 30- minute period, the water was shut off and the amount of water introduced into each of the test borings was recorded. Readings of the change in water level were then recorded at various time intervals over a period of approximately 4 hours. Following testing, the pipes were removed and the test borings were backfilled with on-site soil. The LID infiltration test results are attached in Appendix C. Constant head infiltration testing resulted in introducing up to 10 gallons of water over a period of 30 minutes. The test results indicate moderate to fast rates of infiltration. The test results only indicate the infiltration rates at the specific locations tested and under specific conditions. Sound engineering judgment should be exercised in extrapolating the test results for other conditions or locations. Technical design references vary in methods they present for using these types of test results. However, most references include reduction, safety, and/or correction factors for several parameters including, but not limited to, size of the LID system relative to the test volume, number of tests conducted, variability in the soil profile, anticipated silt loading, anticipated biological buildup, anticipated long-term maintenance, and other factors. Typically, in aggregate these factors range from about 2.5 to 50 depending upon the method used. The final determination of the means by which these data are used is left to the design engineer. 6.0 GENERAL SUBSURFACE PROFILE All of the current borings were performed within paved areas, with the exception of Borings 5 and 8, which had no surface improvements or a thin layer of topsoil . The existing pavement sections consisted of approximately 2.5 inches of PCC in Boring 1, and 6 to 7 inches of AC in the remaining borings; the AC encountered in Boring 6 was underlain by 2 inches of aggregate base . Below the improved or unimproved surfaces, 18 to 40 feet of alluvium was encountered, which was underlain by bedrock of the Franciscan Mélange the continued to the maximum depth explored of approximately 63 feet bgs. The alluvium generally consisted of layers of stiff to hard lean clays with variable amounts of silt, sand and gravel; hard silt; and medium dense to very dense poorly graded and well graded sands with variable amounts of clay, silt and gravel. The bedrock formation underlying the site is the Cretaceous-age Franciscan Mélange; a variably deformed and slightly metamorphosed chaotic assemblage of sedimentary rocks that were accreted at the edge of the North American continent as the Pacific tectonic plate subducted Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 6 1912-016.SER.REV2 beneath North America. This accreted wedge of rocks was subsequently intruded by volcanic rocks, mantled by younger sedimentary rocks, and subjected to continued tectonic deformation and faulting. This complex history has created a rock mass with blocks of relatively undeformed rocks separated by penetratively sheared and crushed zones with somewhat random occurrence and orientations. This rock mass does not conform to the standard “rules” for geologic structure and relationships. The bedrock observed in rock cores at the site ranges from intensely sheared “fault gouge” with geomechanical properties and excavatability of a dense soil, to graywacke sandstone with unconfined compressive strengths (UCS) that ranged from 585 to over 18,000 psi as tested. This range of rock strength is indicative of the wide range of rock properties that may be encountered at the site. A copy of the Geologic Map from the 2011 investigation by this firm is included in Appendix D. Subsurface conditions encountered during the previous investigations were generally consistent with those from this current investigation, with the exception s of approximately 5.5 feet of fill encountered in Boring 4 (ESP 2011) and shale bedrock encountered by Kleinfelder (2005) in Borings 1 and 2 at 40 and 26 feet, respectively. The fill was logged as medium stiff sandy lean clay; the shale was logged as weak to moderately strong. Groundwater was encountered during the current investigation in Borings 5 and 8 at depths of approximately 19.5 feet (Elev. 181.0) and 21.5 feet (Elev. 175.5) bgs, respectively. Groundwater was also encountered in some of the borings previously performed at the site, with levels that ranged from Elev. 166.0 to 177.5. Historical groundwater data was not available in the immediate site area; however, based on our experience in the area and the data presented above, a historical high ground water level at Elev. 184.0 was estimated and used for our analyses. Table 1 below summarizes some of the key data presented above, which includes all exploratory borings performed at the site.

In our opinion, the primary geotechnical engineering concerns at the site are the potential for strong seismic shaking, the potential for significant static settlements, existing undocumented fill, the Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 8 1912-016.SER.REV2 planned excavation adjacent to existing structures and improvements, the soils expansion and corrosion potential, and the residence of shallow groundwater. Liquefaction potential is also discussed. Potential for Strong Seismic Shaking The site is in a region of high seismic activity, with the potential for large seismic events that could generate strong ground shaking. For this project, we were asked to provide seismic design criteria in accordance with CBC 2019/ASCE 7-16. The new methods prescribed by CBC 2019/ASCE 7-16 include significant revisions for determination of site-specific design parameters and further revisions were prescribed in ASCE 7-16 Supplement 1. Seismic acceleration parameters should be utilized in the design of the structures so that potential damage is reduced during a seismic event. These parameters are provided in Table 2 within the “Foundations” Section of this report. Potential for Significant Static Settlements Based on loading information provided by the client and the laboratory test results, our analyses indicate up to 6 inches of total static settlement could occur within the parking structure if column loads stated in the “Introduction and Site Setting” Section were to be supported on conventional shallow foundations. Therefore, the parking structure should be supported by deep foundations bearing in the underlying bedrock. Considering the proximity of structures on the adjacent properties, and the variable depths to and hardness of the underlying bedroc k, driven piles (precast concrete or steel H-piles) would likely not be suitable. Drilled, cast-in-place reinforced concrete caissons are considered most suitable for this project; potential total and differential settlement associated with properly designed and properly constructed deep foundations would likely be negligible. In contrast, approximately 1-inch of total settlement for the theatre was estimated from the anticipated loads; therefore, the theatre structure could be supported by conventional shallow foundations. If conventional shallow foundations are used for the theatre, the elevated walkway between the theatre and the parking structures, as well as any matching finishes between the two buildings, would have to be designed to accommodate approximately 1-inch of differential settlement. Alternatively, the theatre could be supported by deep foundations similar to the parking structure, in which case there would likely be no differential movement between the two structures. Foundation recommendations to address both structures are provided in the “Preliminary Geotechnical Recommendations” Section of this report. Based on the relatively conventional equipment available in the area, caissons appear to be the most feasible option. However, given the depth to bedrock (up to 25 feet below finish floor Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 9 1912-016.SER.REV2 elevation) and the proposed loading, shallow foundations over ground improvement may be a feasible option. The ground improvement elements should extend at least 5 feet into the bedrock and may consist of deep soil-cement mixing, or other methods such as stone or grout columns. Stone or grout columns involve displacing the soil with an auger to the specified depth and consolidating gravel or injecting grout into the resulting soil voids, thus densifying the soil and reducing potential settlements while increasing bearing capacity. C onventional shallow or mat slab foundations could then be constructed over the ground improvement elements. Ground improvement means and methods would be the responsibility of a design -build contractor, and quality control during the design process and construction would be provided by the geotechnical engineer. Most ground improvement contractors are out of the area and costs for mobilization and equipment may not be financially feasible; therefore, if considered, a cost analysis should be performed between options for caissons vs. ground improvement. Existing Fill Fill was encountered in Borings 4 and 8 (ESP 2011), which were located near the northern and southern limits of the site, respectively. The depth of fill at these locations was approximately 5.5 feet and 3 feet, respectively. While the fill encountered within Boring 8 (ESP 2011) will likely be removed during excavation for the flatwork around the theatre, the surface elevation where Boring 4 (ESP 2011) was drilled is nearly the proposed finish floor elevation of the parking structure. As a result, the planned excavation to construct the parking structure would likely not remove the fill. We are unaware of any documentation regarding the placement of the fill. Undocumented fill has more potential for destructive settlement than properly placed and documented fill. Therefore, existing fill should be removed and replaced with properly moisture conditioned and compacted soil, as discussed in the “Grading” Section of this report. Excavation Adjacent to Existing Structures and Improvements Cuts up to 16 feet from existing grades will be required to construct the proposed structures. This mass excavation will extend to within 5 feet of the property lines in some locations. Existing improvements, such as the apartment complex to the east (project east), are within 4 feet of the property line. With consideration to the excavation depths, proximity of the existing structures to the proposed excavation, and the soil types encountered, sloping the excavations will not be possible at several locations and shoring will be necessary to support the walls of the excavation and, the existing structures. Shoring recommendations are provided in the “Shoring” Section of this report. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 10 1912-016.SER.REV2 Soil Expansion Potential Expansion index testing of the alluvium near the proposed finish floor elevation yielded results that ranged from 44 to 76. An additional expansion index test performed during the 2011 investigation (ESP 2011) yielded a result of 87. Per Section 1803.5.3 of the 2019 CBC, these soils are considered to be expansive. The more commonly used ASTM classification is that the soils would be generally considered to have a “low” to “medium” expansion potential. Expansive soils tend to swell with increases in soil moisture and shrink as soil moisture decreases; the upper 3 to 5 feet of soil is the zone most affected by these seasonal soil moisture fluctuations. The volume changes that these materials undergo in this cyclical pattern can damage slabs and foundations if precautionary measures are not incorporated into the design and construction procedures. Recommendations for reducing the potential for damage to the proposed improvements are provided in the “Preliminary Geotechnical Recommendations” Section of this report. Corrosion Potential As indicated in the Soil Corrosivity Study by HDR Engineering, Inc. (see Appendix E), electrical resistivities of the samples tested were in the corrosive to moderately corrosive categories with as received moisture contents; when saturated, the resistivities were in the severely corrosive and corrosive categories. Soil pH values were in the neutral category. The soluble salt contents of the soils were low. Chloride and sulfate were detected at low concentrations. Ammonium was detected in one sample at a low concentration. Nitrate was detected in all samples with one sample concentration high enough to be considered aggressive to copper. The soils were classified as severely corrosive to ferrous metals. Recommendations for mitigation of soil corrosivity are contained in HDR’s Report. Shallow Groundwater Groundwater was measured in our borings as high as Elev. 181.0; however, we anticipate groundwater levels may rise as high as Elev. 184.0 over the design life of the improvements ; therefore, this elevation should be used as the design groundwater level. This elevation is approximately 5 feet below the proposed parking structure finish floor e levation and the lowest finish floor elevation within the theatre. Impacts resulting from shallow groundwater may include wet and unstable soils, difficulty achieving compaction, and difficult utility and foundation installation. Recommendations addressing these potential issues are provided in the “Preliminary Geotechnical Recommendations” Section of this report. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 11 1912-016.SER.REV2 Additionally, the previous FEMA Flood Insurance Rate Map (FIRM) provided in the 2011 report (ESP 2011) indicated the 100-year flood elevation to be at Elev. 192. The current version of the FIRM (FEMA 2012) indicates the 100-year flood elevation to be at approximately 188. With this revision, and the planned lowest level finish f loor elevation of 189, the project would not be subject to inundation from a 100-year flood. However, per the current map, the northwestern corner of the project is within the 500-year flood zone. Liquefaction Potential The site is in an area of moderate liquefaction potential, as mapped by the County of San Luis Obispo (2019). Because of the mapped moderate liquefaction potential, we evaluated the soil layers below the design groundwater level of Elev. 184.0 for liquefaction potential. After correcting blowcounts of the soil layers for depth and hammer efficiency, thes e layers did not show the potential to liquefy during a seismic event; therefore, we anticipate these soils, as well as the underlying bedrock, have very low to no potential for liquefaction. 8.0 PRELIMINARY GEOTECHNICAL RECOMMENDATIONS These recommendations are applicable for the proposed project as described in the “Introduction and Site Setting” Section of this report. If other improvements not previously mentioned are included, the geotechnical engineer should be contacted for revised recommendations. Unless otherwise noted, the following definitions are used in the recommendations presented below. Where terms are not defined, definitions commonly used in the construction industry are intended. • Building Area: The area within and extending a minimum of 5 feet beyond* the perimeter of the foundations of the proposed parking structure and theatre. The building area also includes the footprint of any improvements which are rigidly connected to the structures, such as retaining walls, and that are expected to perform in a similar manner. • Sitework Retaining Wall Area: The area within and extending a minimum of 3 feet beyond* the footprint of any sitework retaining wall foundation. • Flatwork Area: The area within and extending a minimum of 1 foot beyond* the limits of exterior pedestrian flatwork. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 12 1912-016.SER.REV2 • Vehicle Pavement Area: The area within and extending a minimum of 1 foot beyond* the limits of any areas to receive PCC pavement, such as driveways, driveway aprons, and/or trash enclosure pads. • Subgrade: The elevation of the surface upon which a sand cushion/nonexpansive imported material or aggregate base (AB) will be placed for flatwork or pavement, respectively. • Existing Grade: Elevations of the site that existed as of the date of this report. • Finish Pad Grade: The elevation in the building area where earthwork operations are typically considered to be complete. It does not include any sand or gravel that might be placed below slabs in association with vapor protection for the slabs. • Scarified: Thoroughly plowed or ripped in two orthogonal direction s to a depth of not less than 8 inches. • Moisture Conditioned: Soil moisture content adjusted to at least 2 percent above optimum moisture content prior to application of compactive effort. • Compacted/Recompacted: Soils placed in level lifts not exceeding 8 inches in loose thickness and compacted to a minimum of 90 percent of maximum dry density, unless specified otherwise. The standard tests used to establish maximum dry density and field density should be ASTM D 1557-12 and ASTM D 6938-17, respectively, or other methods acceptable to the geotechnical engineer and jurisdiction. * Note: The extents of building, sitework retaining wall, flatwork and vehicle pavement areas are not intended to cross any property lines. Site Preparation 1. The ground surface in the grading area should be prepared for construction by removing all existing improvements, foundations, pavement sections, concrete, vegetation, debris, and other deleterious materials. Any existing utility lines that will not remain in service should be either removed or abandoned. The appropriate method of utility abandonment will depend upon the type and depth of the utility. Recommendations for abandonment during construction can be made as necessary. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 13 1912-016.SER.REV2 2. Voids created by the removal of materials or utilities described above should be called to the attention of the geotechnical engineer. No fill should be placed unless the underlying soil has been observed by the geotechnical engineer. Below-Grade Excavations Temporary Cut Slopes Where possible, excavations may be sloped per OSHA requirements from existing grades to the bottoms of the excavations required to construct the proposed structures, as determined by the contractor’s “competent person.” Where temporary cut slopes are not possible, such as where cuts up to 16 feet from existing grades are proposed, shoring should be implemented to support the planned cuts, as well as adjacent structures and improvements. A discussion of temporary shoring design is provided in the following section: Temporary Shoring Areas where cut slopes are not possible may be supported by temporary shoring. Based on the subsurface conditions encountered, the planned cuts, as well as existing structures and other improvements, may be supported by walls consisting of soldier piles and tiebacks, soil nails, bracing, secant piles, or potentially other methods. Soldier pile walls may be faced with wood or shotcrete lagging. Design provisions for wall design are provided below and in the “Retaining Walls” Section of this report. 1. The shoring system will be supporting existing improvements and structures, as well as potentially providing a facing for the permanent basement walls to be formed against; therefore, wall deflection should be limited and designing the walls for a restrained condition (at-rest pressures) should be considered. 2. Shoring walls should be designed to support the adjacent loading from structures , improvements and vehicles. Generally, one-half of the resulting vertical pressures from these items will result in lateral pressures that should be applied to the full height of the wall. If desired, an analysis for lateral wall pressures resulting from these surcharge loads may be performed on a case-by-case basis. 3. Heavy construction loads, such as cranes and material stockpiles, that will bear near the top of walls should be set back at least 15 feet from the walls. Where this will not be possible, the walls should be designed to support the loading, as discussed above. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 14 1912-016.SER.REV2 4. Voids created by soil sloughing and erosion can cause ground subsidence and deflections in addition to those imparted by lateral wall pressures. Therefore, the contractor should cut the excavations as neatly and vertically as possible. Any voids created within the excavation face should be backfilled as soon as possible with grout or well graded gravel. 5. If shotcrete lagging is proposed, a permanent drainage system should be installed prior to placing the shotcrete. The drainage system should consist of 2 or 4-foot wide vertical drainage panels spaced at 6 or 8-foot centers, respectively. The vertical drainage panels should be connected to horizontal strip drains located at the bottom s of the walls. If installing a drainage system is not desired or feasible, an additional lateral pressure increment of 40 pcf should be added for the entire wall height to account for hydrostatic pressure associated with an undrained wall. If secant pile walls are chosen, installation of wall drainage will likely not be feasible, and the undrained walls should be designed for the additional hydrostatic pressure increment stated above. 6. A drainage system would not be required if wood lagging is proposed for soldier pile walls. Wood lagging is installed with small vertical gaps between the lagging boards, which allows any water present within the exposed soils to drain between the gaps. Some water accumulation at the bottoms of the excavations is likely, and collection of the water should be planned. 7. Due to the potential for surface disturbance, latera l and vertical capacity for shoring foundation elements should not rely on the upper 2 feet of soil below the bottom of the excavation. 8. The recommendations above and in the “Foundations” and “Retaining Walls” Sections of this report have been provided for the use of the design team. The temporary shoring system should be designed by a California-licensed civil or structural engineer who will be in responsible charge for the design, which should include protection of adjacent structures and improvements from lateral movements and subsidence. The shoring contractor is responsible for means and methods during construction of the shoring system, as well as site safety during construction and while the shoring system is the primary means of excavation support. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 15 1912-016.SER.REV2 General 1. Approximately 5.5 feet of fill was encountered in Boring 4 (ESP 2011). Based on the boring surface elevation, it appears that approximately 5 feet of fill could be present below the proposed finish floor elevation. Based on the location of Boring 4 near the northern limit of the site (project north), there is the potential that the fill extends into temporary shoring and permanent foundation areas. Therefore, the fill should be removed and replaced with engineered fill prior to shoring construction, as noted in the “Grading” Section of this report. 2. A pre-construction survey should be performed that will document the conditions of adjacent structures and improvements. The site and surrounding structures and improvements should also be monitored periodically throughout construction. The survey should include establishing benchmarks on adjacent buildings and i mprovements such that periodic measurements can be taken to determine if movement is occurring. The contractor should have an appropriate plan of action ready for immediate implementation in the event that the monitoring program detects movement in the existing improvements. 3. Grading for cut slopes and shoring design should consider the additional cut depth required below finish pad grades to accommodate preparation of native soils and the recommended nonexpansive fill section. 4. Additional and/or augmented geotechnical recommendations may be warranted based upon the proposed cut slopes and shoring system. Grading 1. Following site preparation, the fill materials encountered in Boring 4 (ESP 2011) should be completely removed and the excavation should be cut to a level plane. The exposed surface should then be scarified, moisture conditioned and recompacted. 2. Following site preparation and shoring installation, the building areas should be excavated to at least 18 inches below finish pad elevations. The exposed surfaces should then be scarified, moisture conditioned and recompacted. 3. Following site preparation, sitework retaining wall areas, and flatwork and vehicle pavement areas, should be excavated to bottom of footing elevation and subgrade Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 16 1912-016.SER.REV2 elevation, respectively. The exposed surfaces should then be scarified, moisture conditioned and recompacted. 4. All excavations should extend at a minimum to the depth of disturbance from demolition of existing improvements, where the areas should be graded to level plane, then scarified, moisture conditioned and recompacted. 5. Voids created by dislodging rocks and/or debris during scarifi cation should be backfilled and replaced with appropriate fill material, and the dislodged materials should be removed from the work area. 6. The exposed surfaces within the areas mentioned above should then be backfilled in level lifts with moisture conditioned, compacted site soils or approved imported nonexpansive materials to 18 inches below finish pad grade, subgrade or to bottom of footing elevation. 7. lsolated excavations, such as that required to remove the fill encountered in Boring 4 (ESP 2011), may be required within the proposed improvement areas. To limit the differential settlement that may result when improvements transition from being supported by fill materials to native soils, a gradual transition from fill materials to native materia ls is recommended. This may be accomplished by sloping back excavations no steeper than 3:1 (horizontal:vertical) and keying into the sides of the excavations with each lift of backfill. Backfill at sloped excavations, such as where an excavation will meet a basement wall, should also be keyed into the side of the excavation with each lift. 8. The upper 18 inches of fill below finish pad grade should consist of properly compacted imported nonexpansive material, as described in Paragraph 10 of this section. 9. To limit settlement of improvements constructed over thick fills, such as at wall backfill locations, fills extending more than 5 feet below finished grades should be compacted to a minimum of 93 percent of maximum dry density. The final foot of subgrade and all Class 2 AB (Caltrans 2015) in pavement areas should be compacted to a minimum of 95 percent of maximum dry density. Subgrade and AB should be firm and unyielding when proof- rolled with heavy, rubber-tired grading equipment prior to continuing construction. 10. Nonexpansive materials are defined as materials that fall in the GW, GP, GM , GC, SP, SW, SC and SM categories per ASTM D 2487-17, and that have an expansion index of 10 or less Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 17 1912-016.SER.REV2 (ASTM D 4829-11). Proposed nonexpansive materials should be reviewed by the geotechnical engineer before being brought to the site, and on an intermitten t basis during placement. 11. All materials used as fill should be cleaned of all debris and any rocks larger than 3 inches in maximum dimension. When fill material includes rocks, the rocks should be placed in a sufficient soil matrix to ensure that voids caused by nesting of the rocks will not occur and that the fill can be properly compacted. 12. If the soils become unstable, or if the recommend ed compaction cannot be readily achieved, drying the soil to optimum moisture content, or just above, may be necessary. Placement of gravel layers or geotextiles may also be necessary to help stabilize unstable soils. Soils that are disturbed in any manner should be removed, moisture conditioned, and recompacted. 13. The recommended soil moisture content should be maintained throughout construction. Failure to maintain the soil moisture content can result in cracks and disturbance, which are an indication of degradation of the soil compaction. If cracks are allowed to develop, or if soils near improvements such as foundations, flatwork, pavement, curbs, etc. are otherwise disturbed, damage to those improvements may result. Soils that have been or are otherwise disturbed should be removed, moisture conditioned, and compacted. 14. Permanent cut and fill slopes should not exceed a 2:1 (horizontal: vertical) gradient, unless otherwise recommended by the geotechnical engineer. Utilities 1. Any utility trenches that extend below Elev. 184 may encounter groundwater. If groundwater is encountered during utility trench excavation, the trench should be dewatered until it can be properly backfilled per the recommendations provided below and per the requirements of the architect/engineer. 2. Unless otherwise recommended, utility trenches adjacent to foundations should not be excavated within the zone of foundation influence, as shown in Typical Detail A in Appendix F. 3. Utilities that must pass beneath a foundation should be placed with properly compacted utility trench backfill and the foundation should be designed to span the trench. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 18 1912-016.SER.REV2 4. A select, non-corrosive, granular, easily compacted sand should be used as bedding and shading immediately around utilities. All trench backfill above the select material within the building, flatwork, and pavement areas should consist of properly compacted non - expansive material or AB, as defined in the “Grading” Section of this report. The site soils may be used for trench backfill above the select material within landscape, or otherwise unimproved areas. 5. In general, trench backfill should be compacted to a minimum of 90 percent of maximum dry density. The upper 12 inches of subgrade and all aggregate base for trench backfill in vehicle pavement areas should be compacted to a minimum of 95 percent of maximum dry density. 6. Trench backfill should be placed in level lifts, moisture conditioned, and compacted to the minimums noted above. 7. Compaction of trench backfill by jetting or flooding is not recommended except under extraordinary circumstances. However, to aid in encasing utility conduits, particularly corrugated drain pipes, and multiple, closely spaced conduits in a single trench, jetting or flooding may be useful. Flooding or jetting should only be attempted with extreme caution, and any jetting operation should be subject to review by the geotechnical engineer. 8. Recommendations for protection of utilities from soil corrosivity are provided in the report by HDR, Inc., in Appendix E. 9. The recommendations of this section are minimums only and may be superseded by the requirements of the architect/engineer, the recommendations of pipe manufacturers or utility companies, or the requirements of the governing jurisdiction based upon soil corrosivity or other factors. Foundations Ground Motion Analyses In accordance with 2019 CBC and ASCE 7-16 an assessment was made to determine the need for employing “Site-Specific Ground Motion Procedures” to determine the ground motion parameters for the project. The S1 ground motion value obtained from the Structural Engineers Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 19 1912-016.SER.REV2 Association of California website (SEAOC 2019) using the ASCE 7-16 (2016), for Site Class D “Stiff Soil”, was 0.39g, greater than 0.2; therefore, per Section 11.4.8.3 of ASCE 7-16, the project requires site-specific ground motion analyses. A risk-targeted maximum considered earthquake (MCER) modeling procedure was performed in accordance with ASCE 7-16, including a Probabilistic Seismic Hazard Analysis (PSHA); a Deterministic Ground Motion Analysis (DGMA) was not required because the PGA calculated for the PHSA (0.840) is less than 1.2, in accordance with ASCE 7-16 Supplement 1. The analysis is based on knowledge of the regional tectonic setting, geology, and seismicity. A Probabilistic Seismic Hazard Analysis (PSHA) using the United States Geologic Survey (USGS, 2019b) Unified Hazard Tool was used to access the Third California Earthquake Rupture Forecast (UCERF3) database and the Risk-Targeted Ground Motions Calculator (USGS 2019a) was used to estimate potential ground motions at the project site. The PSHA was performed in general accordance with Section 21.2.1.2, Method 2, of ASCE 7-16 to estimate the peak ground motion corresponding to the uniform hazards earthquake and MCE R which has a 2% probability of being exceeded in 50 years. For analysis purposes, we assumed the Los Osos fault as the causative fault, located 2.4 miles from the site. The Los Osos fault is a reverse-oblique fault and we specified footwall conditions for the attenuation relationships. A magnitude of 6.8 was used as a basis to model fault rupture. The primary seismic risks are from earthquakes generated by the local Los Osos, Rinconada, San Luis Range and Hosgri-San Simeon faults and the more distant San Andreas fault. The 2019 CBC seismic design criteria are based on a Design Earthquake that produces ground motion 2/3 of the lesser of an earthquake with 2 percent probability of occurrence in 50 years, or maximum 84th percentile of the mean deterministic MCE. In this case the probabilistic spectra governed, scaled in accordance with ASCE 7-16 procedures. Seismic Design Category Section 1613.2.5 of the 2019 CBC states that structures classified as Risk Category I, II, or III that are located where the mapped spectral response acceleration parameter at 1 -second period, S1, is greater than or equal to 0.75 shall be assigned to Seismic Design Category E. The S1 calculated for the site is 0.39, less than 0.75; therefore, the site should be assigned to the seismic design category based on risk category and the design spectral response acceleration parameters SDS Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 20 1912-016.SER.REV2 and SD1. The site falls under Risk Category II, per Table 1604.5 of the 2019 CBC, and S DS and SD1 are 0.695 and 0.565, respectively. Applying this risk category and these acceleration parameters to Tables 1613.2.5(1) and (2) resulted in a classification of Seismic Design Category D. Seismic Design Parameters This site may be subject to strong ground shaking due to potential fault movements along regional faults including the Los Osos fault, whose proximity was considered during our site- specific analysis. Engineered design and earthquake-resistant construction increase safety and allow development of seismically active areas. The minimum seismic design should comply with the 2019 edition of the California Building Code and ASCE 7-16. The resulting seismic coefficients considering Site Class D are given in the table below. TABLE 2: SEISMIC PARAMETERS (2019 CBC/ASCE 7-16) Seismic Design Category D Site Class D Mapped and Code Based Ground Motion Short Period Spectral Response, Ss 1.057 g 1 Second Mapped Spectral Response, S1 0.390 g Design Earthquake Ground Motion Short Period Spectral Response, SDS 0.695 g 1 second Spectral Response, SD1 0.565 g Peak Ground Acceleration (PGAM) 0.550 g MCE Spectral Response Acceleration Short Period Spectral Response, SMS 1.043 g 1 Second Period Spectral Response, SM1 0.847 g Site Amplification Factors Short Period Site Coefficient, Fa 1.077 1 Second Period Site Coefficient, Fv 2.5 Vertical Site Coefficient, Cv 1.31 Risk Coefficient (Short Period), CRs 0.889 Risk Coefficient (1 Second Period), CR1 0.902 Acceleration values provided are estimates only. The estimated peak horizontal site acceleration based upon a probabilistic analysis (2 percent probability of occurrence in 50 years) is approximately 1.4 g for this site. Actual accelerations may be more or less than estimated. Vertical accelerations are typically ⅓ to ⅔ of the horizontal accelerations, but can equal or exceed the horizontal accelerations, depending upon the local site effects and amplification. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 21 1912-016.SER.REV2 General 1. Due to the relatively large potential static settlements resulting from the proposed structural loading, supporting the proposed parking structure on conventional shallow foundations is not recommended. The parking structure should be supported on deep foundation consisting of drilled, cast-in-place reinforced concrete caissons. Column and wall loads for the theatre will be relatively small with much smaller corresponding anticipated settlements; therefore, the theatre may be supported on conventional shallow foundations, or on deep foundations. 2. Recommendations for protection of cast-in-place concrete foundation elements are provided in the report by HDR, Inc. in Appendix E. 3. If the theatre is supported by drilled, cast-in -place concrete caissons similar to those supporting the parking structure, the planned elevated walkway between the two structures would likely experience negligible differential settlement. However, if the theatre is supported by conventional shallow foundations, the elevated walkway should be designed to accommodate up to 1 inch of differential settlement. Drilled, Cast-in-Place Concrete Caissons – Parking Structure, Theatre or Sitework Retaining Walls 1. The caissons may be designed using a downward (compressive) allowable skin friction value of 700 psf for the alluvium and 1,500 psf within the Franciscan Mélange bedrock. The caissons should be embedded a minimum of 10 feet into the underlying bedrock. No end bearing capacity should be used in the calculations. 2. Allowable skin friction values of 450 psf and 1,000 psf can be used for short-term tension (uplift) conditions within the alluvium and bedrock, respectively. The self-weight of the caissons may be neglected in the determination of loading, however it may be included, if needed, for resistance to uplift. 3. The allowable skin friction values for the caissons may be increased by one-third when transient loads such as wind or seismicity are included. Foundations should be designed using the site design response parameters to be provided in an addendum 4. An ultimate passive resistance based on an equivalent fluid pressure of 350 pcf up to a maximum uniform pressure of 2,000 psf, acting over 2 caisson diameters, may be taken Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 22 1912-016.SER.REV2 for resistance to short term lateral loads within the alluvium. The maximum uniform pressure above may be increased to 4,000 psf within the bedrock. The structural engineer should apply an appropriate factor of safety to the ultimate values presented above. 5. As foundation design progresses Lpile parameters can be provided as needed. 6. Grade beams between caissons should be a minimum of 12 inches wide and 24 inches deep. Based on soil expansion potential only, minimum grade beam reinforcement should consist of one No. 5 rebar, top and bottom. 7. As the caissons will penetrate into the underlying bedrock, a group effect may be neglected in the design. However, closely spaced caissons may require special considerations with respect to resistance to lateral loads and construction methods. Caissons should not be constructed closer than three caisson diameters to each other without approval from the geotechnical engineer. 8. Subsurface water was encountered in many of the explorations and will be encountered during the caisson drilling operations; therefore, caisson reinforcing should be designed to accommodate a minimum 5-inch diameter tremie pipe for concrete placement. The reinforcing should also be designed to facilitate removal of the casing during concrete placement, and additional coverage over reinforcing steel is recommended to account for likely difficult concrete placement conditions. All water encountered should be removed from the caisson excavation prior to placing concrete, or the concrete should be tremied. The tremie method is described in Appendix F. 9. As the caissons will utilize skin friction in the bedrock for support, it is not necessary to remove all loose debris and slough material from the bottoms of the excavations, although the majority of loose debris and slough material shou ld be removed by means of a clean-out bucket. 10. Concrete used in caissons should be placed at a slump between 6 and 8 inches in dry excavations and between 8 and 10 inches when placed under water. The concrete in the upper 8 to 10 feet of the caissons should be mechanically consolidated following placement. 11. The caissons should not deviate from a plumb line taken from the center of the caisson by more than 2 percent of the caisson length, from the top to the point of interest. Adequate caisson oversize may be assumed to provide required tolerance. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 23 1912-016.SER.REV2 12. All caisson excavations should be filled with concrete on the same day as they are drilled. If this is not practicable, the caissons should be secured in a safe manner in conformance with OSHA requirements or other applicable safety standards until concrete can be placed. Any caisson excavation that has not been filled with concrete on the same day as it was drilled should have the surfaces “freshened” by extending the rotating auger into and out of the hole several times, immediately prior to placement of the concrete. The bottom of the hole should then be cleaned out again by means of the clean -out bucket. 13. Caisson excavations should be observed by the geotechnical engineer during drilling operations to confirm the subsurface conditions and prior to placement of reinforcing steel and concrete. Special inspection of reinforcing steel and concrete placement for caissons should also be provided. 14. Soils in grade beam excavations should be moistened to optimum moisture content or just above, and no desiccation cracks should be present, prior to concrete placement. Conventional Shallow Foundations – Theatre and Sitework Retaining Walls 1. Continuous and spread footings may be used to support the proposed theatre and sitework retaining walls. The footings should be constructed with a minimum overall depths of 24 inches below lowest adjacent grade. The theatre foundations should bear in neatly cut excavations into firm undisturbed native soils. If firm conditions are not present at design bottom of foundation elevation, localized deepening of foundation excavations will be necessary. Retaining wall foundations should bear in neatly cut excavations into firm compacted fill, as described in the “Grading” Section of this report. Footing excavations should be horizontal and stepped as needed to bear in uniform material. 2. Continuous footings and grade beams should be reinforced, at a minimum, by two No. 5 rebar, one at the top and one at the bottom, or as required by the architect/engineer. Spread footings should be reinforced in accordance with the requirements of the architect/engineer. 3. Footings bearing into undisturbed native soils or firm compacted fill may be designed using maximum allowable bearing capacities of 2,000 psf for dead loads and 3,000 psf for dead plus live loads. Using these criteria, maximum settlement and differential settlement are expected to be on the order of 1-inch and ⅔-inch over a horizontal distance of 25 feet, respectively. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 24 1912-016.SER.REV2 4. Allowable capacities may be increased by one-third when transient loads such as wind or seismicity are included. Foundations should be designed using the site design response parameters to be provided in an addendum. 5. In calculating resistance to lateral loads, ultimate passive equivalent fluid pressures of 350 pcf may be used for foundations bearing in undisturbed native soils or compacted fill. A coefficient of friction of 0.40 may also be utilized in the design. The lateral capacities are based on the assumption that the soil adjacent to the foundations is undisturbed and/or properly compacted. Passive and friction resistance components may be combined in the analysis without reduction to either value. An appropriate factor of safety should be applied to the values presented above. 6. Foundation excavations should be observed by the geotechnical engineer during excavation and prior to placement of formwork, reinforcing steel or concrete. Soil in foundation excavations should be moistened to optimum moisture content or above and no desiccation cracks should be present prior to concrete placement. Interior Slabs-on-Grade and Exterior Pedestrian Flatwork Interior Slabs-on-Grade 1. Interior slabs-on-grade for non-vehicle use should have a minimum thickness of 4 inches. They should be reinforced and doweled to foundations per the specifications of the architect/engineer. At a minimum, interior slabs should be reinforced with No. 3 rebar placed at 24 inches on center each way. All structural slabs should contain minimum rebar meeting the criteria of ACI 318, Section 24.4 (ACI 2014). At a minimum, foundation dowels should be lap spliced to the slab rebar. The size and spacing of the dowels should match the size and spacing of the slab rebar. Exterior Pedestrian Flatwork 1. Exterior pedestrian flatwork should have a minimum thickness of 4 inches. Minimum reinforcement for exterior pedestrian flatwork should consist of No. 3 rebar placed at 24 inches on-center each way. 2. In conventional construction, it is common to use 4 to 6 inches of imported sand beneath exterior pedestrian flatwork. However, due to the moderate expansion potential of the site soils, there will be a risk of movement and damage to the flatwork and slabs if Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 25 1912-016.SER.REV2 conventional measures are used. Heaving and cracking could occur. To reduce the potential for movement and damage, flatwork and slabs should be supported on at least 18 inches of nonexpansive imported soils. 3. To further reduce the risk of movement of flatwork due to seasonal moisture variations or loss of soil from erosion, thickened edges or grade beams can be provided around the perimeters of the flatwork. At a minimum, any thickened edge or grade beam should be reinforced by two No. 4 rebar, one at the top and one at the bottom. 4. It is recognized that the measures recommended in the previous paragraph for protecting exterior flatwork from seasonal moisture variations are an added expense, possibly more expensive than simply replacing flatwork that has settled and/or cracked. Consequently, the above measures for protecting exterior flatwork are only suggestions for consideration by the owner and/or architect/engineer. The degree to which exterior flatwork is protected is left to the discretion of the owner and/or architect/engineer. 5. Flatwork should be constructed with frequent joints to allow articulation as the flatwork moves in response to seasonal soil temperature and moisture variations. The soil below flatwork should be moisture conditioned prior to casting the flatwork. 6. Flatwork at doorways, and at other areas where maintaining the elevation of the flatwork is desired, should be doweled to the perimeter foundations, at a minimum, by No. 3 dowels lapped to the flatwork rebar at 24 inches on center. In other areas, the flatwork may be doweled to the foundation or the flatwork may be allowed to “float free,” at the discretion of the architect/engineer. Flatwork that is intended to float free should be separated from foundations by a felt joint or other means. Moisture Vapor Transmission 1. Due to the current use of impermeable floor coverings, water-soluble flooring adhesives, and the speed at which buildings are now constructed, moisture vapor transmission through slabs is a much more common problem than in past years. Where moisture vapor transmitted from the underlying soil would be undesirable, the slabs should be protected from subsurface moisture vapor. A number of options for vapor protection are discussed below; however, the means of vapor protection, including the type and thickness of the vapor retarder, if specified, are left to the discretion of the architect/engineer. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 26 1912-016.SER.REV2 2. Where specified, vapor retarders should conform to ASTM Standard E1745-17. This standard specifies properties for three performance classes, Class “A”, “B” and “C”. The appropriate class should be selected based on the potential for damage to the vapor retarder during its installation and placement of slab reinforcement and concrete. 3. It should be noted that ASTM E 1745-17 has the same permeance threshold for Class A through Class C (0.1 perms). The class that is chosen will make a difference in how resistant the vapor retarder is to punctures and tears, but it will not insure any better permeance values to protect floor coverings. 4. Several recent studies, including those of ACI Committee 302 (ACI 2015), have concluded that excess water above the vapor retarder increases the potential for moisture damage to floor coverings and could increase the potential for mold growth or other microbial contamination. The studies also concluded that it is preferable to eliminate the typical sand layer beneath the slab and place the slab PCC in direct contact with a vapor retarder, particularly during wet weather construction. However, placing the PCC directly on the vapor retarder requires special attention to specifying the proper vapor retarder, a very low water-cement ratio in the PCC mix, and special finishing and curing techniques. 5. Another option for vapor protection would be the use of vapor-inhibiting admixtures in the slab PCC mix and/or application of a sealer to the surface of the slab. This would also require special PCC mixes and placement procedures, depending upon the recommendations of the admixture or sealer manufacturer. 6. A third option that may be a reasonable compromise between effectiveness and cost considerations would be the use of a subslab vapor retarder protected by a layer of granular material or of clean sand, with the granular material being the preferred choice. The granular material should be easily compactible and have a relatively low fines content and a low wicking potential; virgin Class 2 AB (Caltrans 2015) meets these criteria. Clean sand is defined as a well or poorly graded sand (ASTM D2487-17) of which less than 3 percent passes the No. 200 sieve. The retarder should be covered with a minimum 4 inches of granular material or clean sand. If a Class “A” vapor retarder is specified, the retarder can be placed directly on the compacted soil material. If a less durable vapor retarder is specified (Class “B” or “C”), a minimum of 1 inch of fine-graded material such as a clean sand should be placed over the compacted soil material to reduce the chance of puncturing the vapor retarder. The materials mentioned above may count as part of the nonexpansive fill section, not in addition to it. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 27 1912-016.SER.REV2 7. If sand is used between the vapor retarder and the slab, it should be moistened only as necessary to promote concrete curing; saturation of the sand should be avoided, as the excess moisture would be on top of the vapor retarder, potentially resulting in vapor transmission through the slab for months or years. 8. Regardless of the underslab vapor retarder selected, proper installation of the retarder is critical for optimum performance. Where utilized, the vapor retarder should be placed a minimum of 1 inch above the flow line of the drainage path surrounding the structures, or 1 inch above the area drain grates if area drains are used to collect runoff around the structures. All seams must be properly lapped, and all seams and u tility penetrations properly sealed in accordance with the vapor retarder manufacturer’s recommendations and ASTM E1643-18a. At the terminating edges of the vapor retarder, the vapor retarder should be effectively sealed with accessories specifically designed to seal the material to new or existing concrete; details for edge sealing of the vapor retarder should be provided by the architect/engineer. Slabs-on-Grade - General 1. To reduce shrinkage cracks in all interior and exterior slabs-on-grade, the concrete aggregates should be of appropriate size and proportion, the water/cement ratio should be low, the concrete should be properly placed and finished, contraction joints should be installed, and the concrete should be properly cured. This is particularly applicable to slabs that will be cast directly upon a vapor retarder and those that will be protected from transmission of vapor by use of admixtures or surface sealers. Concrete materials, placement, and curing specifications should be at the direction of the architect/engineer; AC 302.1R-15 (ACI 2015) is suggested as a resource for the architect/engineer in preparing such specification. 2. The structural engineer should consider the potential for hydrostatic uplift pressure o n slabs-on-grade due to the potential for nearby flooding during 100-year and 500-year events. Retaining Walls 1. Retaining walls should be founded in firm soil that has been recompacted per the “Grading” Section of this report. Retaining wall footings should be reinforced in accordance with the requirements of the architect/engineer; minimum retaining wall footing reinforcement should consist of one No. 4 rebar top and bottom. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 28 1912-016.SER.REV2 2. Retaining wall design may be based on the following parameters: TABLE 3: RETAINING WALL DESIGN PARAMETERS Parameter Backfill Type Value Active Equivalent Fluid Pressure Site Soils 45 pcf Active Equivalent Fluid Pressure Imported Sand/Gravel 35 pcf At-Rest Equivalent Fluid Pressure Site Soils 60 pcf At-Rest Equivalent Fluid Pressure Imported Sand/Gravel 50 pcf Passive Equivalent Fluid Pressure Onsite or Imported Recompacted Soil 350 pcf Maximum Toe Pressure Onsite or Imported Recompacted Soil 3,000 psf Coefficient of Sliding Friction Onsite or Imported Recompacted Soil 0.40 3. The pressures provided above should also be applied to shoring elements. 4. The active and at-rest pressures are applicable to a horizontal retained surface behind the wall. Walls having a retained surface that slopes upward from the wall should be designed for an additional equivalent fluid pressure of 1 pcf for the active case and 1.5 pcf for the at-rest case, for every degree of slope inclination. 5. As with shoring walls, permanent retaining walls should be designed to support the adjacent loading from structures, improvements and vehicles. Generally, one -half of the resulting vertical pressures from these items will result in lateral pressures that should be applied to the full height of the wall. If desired, an analysis for lateral wall pressures resulting from these surcharge loads may be performed on a case-by-case basis. 6. The upper foot of backfill behind all retaining walls should consist of native soil, except in areas where exterior pedestrian flatwork or PCC pavements for vehicle use will abut the top of the wall. In such cases, the backfill soil should extend to the sand, aggregate base, or other material below the improved surface, as appropriate. If gravel backfill is utilized, the gravel should be encased in a permeable synthetic filter fabric conforming to standard specification section 96-1.02B – Class C (Caltrans 2015). 7. Under the 2019 CBC, the Risk-Targeted Maximum Considered Earthquake (MCER) must be used for determining seismic pressures on walls. Further, Section 1807.2.2 of the 2019 CBC requires that dynamic seismic lateral earth pressures be provided by the geotechnical engineer for walls retaining more than 6 feet of backfill. The Structural Engineers Association of California website (SEAOC 2019) was used to determine the MCER-based Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 29 1912-016.SER.REV2 Geometric Mean Peak Ground Acceleration (PGAM) for a Seismic Design Category “D” project. The resulting PGAM was 0.530g. Then, using the methods presented by Lew et al. (2010) and this PGAM, it was determined that no incremental increase in lateral soil pressure above the static active equivalent fluid pressure for flexible (cantilevered) walls was required for the native clayey soils; however, a pressure increase of 10 pcf was determined for imported sand or gravel backfill. Flexible (cantilevered) walls retain ing over 6 feet of backfill should be designed using these incremental seismic pressures. Walls retaining 6 feet or less of backfill need not be designed for seismic pressures. 8. Recent research by Al Atik and Sitar (2010) confirmed that for flexible (cantilevered) walls, particularly those over 12 feet tall, an increase in soil pressure does occur under significant seismic accelerations. Further, they found that the increase is due to the out - of-phase interaction between the soil and the flexible wall. Whe n considering rigid walls (i.e. those designed using at-rest criteria); however, they found that the incremental increase due to seismicity was typically less than 50 percent of the static wall pressure. Consequently, no incremental increase in lateral soil pressure is recommended for the design of walls where the static design utilizes the at -rest equivalent fluid pressure and they are designed with factors of safety and earth load factors of at least 1.5. 9. In typical structural design methods for retaining walls such as those found in Section 1605 of the 2019 CBC, lateral soil pressure is multiplied by a load factor of 1.6. According to Lew et al. (2010), a load factor of 1.6 is too conservative for seismic loads; this paper suggests that the seismic increase in lateral pressure be separated from the static active pressure and that a load factor of 1.0 be used for the seismic increase. Further, Al Atik and Sitar (2010) found that pressure increases due to seismic earth loads were minimal for walls retaining less than 12 feet of backfill. While Al Atik and Sitar’s research is generally accepted among geotechnical and structural engineers in California, it is not entirely acknowledged by the CBC, as the CBC sets the height below which seismic loads may be ignored at 6 feet. Given this disparity, it is suggested that caution be used not to over-engineer walls retaining between 6 and 12 feet of backfill. 10. Long-term settlement of properly compacted native soil retaining wall backfill or imported sand/gravel backfill should be assumed to be about 0.5 and 0.25 percent of the depth of the backfill, respectively. Improvements that are constructed near the tops of retaining walls should be designed to accommodate long-term settlement. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 30 1912-016.SER.REV2 11. All retaining walls, including basement walls, should be designed as drained walls. The wall drainage design may consist of a conventional system that includes perforated pipe encased in a free-draining gravel blanket or of a manufactured synthetic drainage system that consists of drainage panels that direct water flow into an integrated subdrain . 12. For the conventional system, the pipe should be placed with perforations facing downward, and should discharge in a non-erosive manner away from foundations and other improvements. The gravel blanket should have a width of approximately 1 foot and should extend upward to approximately 1 foot below the top of the wall backfill. The upper foot should be backfilled with native soil, except in areas where exterior pedestrian flatwork will abut the top of the wall. In such cases, the gravel should extend to the sand, aggregate base, or other material below the improved surface, as appropriate. To reduce infiltration of the soil into the gravel, a permeable synthetic filter fabric conf orming to Standard Specifications Section 96-1.02B – Class C (Caltrans 2015), should be placed between the two. 13. Manufactured synthetic drains, such as Miradrain or Enkadrain are acceptable alternatives to the use of gravel, provided they are installed in accordance with the recommendations of the manufacturer. The integrated subdrain should discharge in a non-erosive manner away from foundations and other improvements. The drainage panels should extend upward to approximately 1 foot below the top of the wall backfill. 14. Where weep hole drainage can be properly discharged, the perforated pipe or integrated subdrain may be omitted in lieu of weep holes on maximum 4-foot centers. A filter fabric as described above should be placed between the weep holes and the drain gravel when applied to a conventional drainage system. 15. If drainage cannot be provided for permanent walls or temporary shoring walls, an additional lateral hydrostatic pressure increment of 40 pcf should be applied over the entire height of the wall. 16. Walls facing areas where moisture transmission through the wall would be undesirable should be thoroughly waterproofed in accordance with the specifications of the architect/engineer. 17. The architect/engineer should bear in mind that retaining walls by their nature are flexible structures, and that surface treatments on walls often crack. Where walls are to be plastered or otherwise have a finish applied, the flexibility should be consid ered in Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 31 1912-016.SER.REV2 determining the suitability of the surfacing material, spacing of horizontal and vertical control joints, etc. The flexibility should also be considered where a retaining wall will abut or be connected to a rigid structure, and where the geometry of the wall is such that its flexibility will vary along its length. Vehicle PCC Pavements 1. If plain Portland cement concrete pavement is preferred (instead of reinforced concrete), the following minimum section is recommended • 8 inches plain PCC (4,000 psi minimum) • No. 4 smooth dowels at 12-inch centers at concrete joints • 12 inches Class 2 AB (Caltrans 2015) compacted to a minimum of 95 percent of maximum dry density • 12 inches subgrade, compacted to a minimum of 95 percent of maximum dry density 2. If reinforced concrete pavement is preferred, the following minimum section may be used: • 6 inches PCC (4,000 psi minimum) • No. 3 rebar at 24-inch centers each way • No. 3 smooth joint dowels at 24-inch centers • 12 inches Class 2 AB (Caltrans 2015) compacted to a minimum of 95 percent of maximum dry density • 12 inches subgrade, compacted to a minimum of 95 percent of maximum dry density 3. Alternately, the pavement may be designed by the architect/engineer for the appropriate loads. Provided that a minimum of 12 inches of compacted Class 2 AB is under the pavement, the design may be based on a modulus of subgrade reaction (k30) of 200 pci (psi/in). Specification of concrete properties and reinforcing is left to the architect/engineer. 4. The above sections should apply to the parking structure basement slabs as well as trash enclosures and stress pads, with the exception that the 18-inch thick nonexpansive fill section is satisfied. This section may consist of an additional 6 inches of Class 2 AB or other nonexpansive materials discussed in the “Grading” Section of this report. Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 32 1912-016.SER.REV2 5. Pavement surfaces should be sloped to freely drain toward appropriate drainage facilities. Water should not be allowed to stand or pond on or adjacent to pavement or other improvements as it could infiltrate into the AB and/or subgrade, causing premature pavement deterioration. 6. To reduce migration of surface drainage into the subgrade, maintenance of pavement areas is critical. Any cracks that develop in the pavement should be promptly sealed. 7. The local jurisdiction may have additional requirements for pavement that could take precedence over the above recommendations. Drainage and Maintenance 1. Unpaved ground surfaces should be graded during construction and, per Section 1804.4 of the CBC, finish graded to direct surface runoff away from foundations, slopes, and other improvements at a minimum 5 percent grade for a minimum distance of 10 feet. If this is not feasible due to the terrain, property lines, or other factors, swales with improved surfaces, area drains, or other drainage features should be provided to divert drainage away from these areas. 2. Paved surfaces should provide positive drainage away from foundations, slopes and other improvements. 3. Where infiltration stormwater control measure areas will lie within 10 feet of a foundation, flatwork, pavement, or other similar surface improvement, moisture protection should be provided between the infiltration feature and the improvement. Moisture protection should consist of curbs or impermeable liners, deepened to a minimum of 2 feet below foundations, or 1 foot below the bottom of the infiltration facility, whichever is deeper. 4. To reduce the potential for planter drainage gaining access to subslab areas, any raised planter boxes adjacent to foundations should be inst alled with drains and sealed sides and bottoms. Drains should also be provided for areas adjacent to the structure that would not otherwise freely drain. 5. The eaves of the proposed buildings should be provided with roof gutters. Runoff from roof gutters, downspouts, area drains, weep holes, etc., should discharge to an Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 33 1912-016.SER.REV2 appropriate outlet in a nonerosive manner away from foundations and other improvements in accordance with the requirements of the governing agencies. Erosion protection should be placed at all discharge points unless the discharge is to a pavement surface. 6. To reduce the potential for damage due to erosion it is essential that the surface soils, particularly those disturbed during construction, be stabilized by vegetation or other means during and following construction. Care should be taken to establish and maintain vegetation. The landscaping and exterior flatwork should be installed to maintain the surface drainage recommended above. 7. To reduce the potential for disruption of drainage patterns and undermining of foundations and other improvements, rodent activity should be aggressively controlled. Observation and Testing 1. It must be recognized that the recommendations contained in this report are based on a limited number of borings and rely on continuity of the subsurface conditions encountered. Therefore, the geotechnical engineer should be retained to provide consultation during the design phase, to review plans as they near completion, to interpret this report during construction, and to provide construction monitoring in the form of testing and observation. 2. At a minimum, the geotechnical engineer should be retained to provide: • Review of the project plans as they near completion • Professional observation during grading and backfill • Oversight of soil special inspection • Oversight of special inspection for shallow and deep foundation excavation/installation 3. Special inspection of grading and backfill should be provided as per Section 1705.6 and Table 1705.6 of the 2019 CBC. The special inspector should be under the direction of the geotechnical engineer. It is our opinion that none of the grading construction is of a nature that should warrant continuous special inspection; periodic special inspection should suffice. Subject to approval by the Building Official, the exception to continuous special inspection is described in Section 1704.2 of the 2019 CBC and should be specified Palm-Nipomo Street Parking Structure December 13, 2019 and Repertory Theatre (Revised January 7, 2020) 303310-001 34 1912-016.SER.REV2 by the architect/engineer and periodic special inspection of the following items should be provided by the special inspector. • Stripping and clearing of vegetation and unsuitable materials • Shoring installation observation • Overexcavation to the recommended depths • Scarification, moisture conditioning, and compaction of the soil • Fill quality, placement, and compaction • Utility trench backfill • Foundation excavations • Retaining wall drains and backfill • Subgrade and AB compaction and proof-rolling 4. Continuous special inspection of the cast-in-place deep foundation installation should be provided as per Section 1705.8 of the 2019 CBC. The special inspector should be under the direction of the geotechnical engineer. 5. A program of quality control should be developed prior to beginning grading. The contractor or project manager should determine any additional inspection items required by the architect/engineer or the governing jurisdiction. 6. Locations and frequency of compaction tests should be as per the recommendation of the geotechnical engineer at the time of construction. The recommended test location s and frequency may be subject to modification by the geotechnical engineer, based upon soil and moisture conditions encountered, size and type of equ ipment used by the contractor, the general trend of the results of compaction tests, or other factors. 7. A preconstruction conference among the owner, the geotechnical engineer, the governing agency, the special inspector, the project inspector, the architect/engineer, and contractors is recommended to discuss planned construction procedures and quality control requirements. 8. The geotechnical engineer should be notified at least 48 hours prior to beginning construction operations.

Wednesday, October 16, 2019 via email: nzoetewey@earthysystems.com ERnrH Svsre¡¡s PRcrnc 4378 Old Santa Fe Road San Luis Obispo, CA 93401 Attention: Mr. Nick Zoetewey Re: Soil Corrosivity Study Palm-Nipomo Street Parking Structure San Luis Obispo, CA HDR #1 9-0663, 30331 0-001 lntroduction Field and laboratory tests have been completed for the Palm-Nipomo Street Parking Structure project. Laboratory tests have been completed on four soil samples provided to HDR for the referenced project. The purpose of these tests was to determine if the soils might have deleterious effects on underground utility piping, hydraulic elevator cylinders, and concrete structures. HDR Engineering, lnc. (HDR) assumes that the samples provided are representative of the most corrosive soils at the site. The proposed structure has up to five stories and one subterranean level. The site is located at Palm Street and Nipomo Street in San Luis Obispo, California, and the water table is reportedly 6.5 feet deep. The scope of this study is limited to a determination of soil corrosivity and general corrosion control recommendations for materials likely to be used for construction. HDR's recommendations do not constitute, and are not meant as a substitute for, design documents for the purpose of construction. Laboratory Soil Corrosivity Tests The electrical resistivity of each sample was measured in a soil box per ASTM Gl87 in its as-received condition and again after saturation with distilled water. Resistivities are at about their lowest value when the soil is saturated. The pH of the saturated samples was 431 W. Baseline Road, Claremont, CA 91711-1608 (909) 626-0967 hdrinc.com EARTH SysTEMs PAjIFIC HDR #19-0663SCS October 16, 2019 Page 2 measured per ASTM G51. A 5:1 water:soil extract from each sample was chemically analyzed for the major soluble salts commonly found in soil per ASTM D4327, ASTM D6919, and Standard Method 2320-E1. Laboratory test results are shown in the attached Table 1. Soil Corrosivity A major factor in determining soil corrosivity is electrical resistivity. The electrical resistivity of a soil is a measure of its resistance to the flow of electrical current. Corrosion of buried metal is an electrochemical process in which the amount of metal loss due to corrosion is directly proportional to the flow of electrical current (DC) from the metal into the soil. Corrosion currents, following Ohm's Law, are inversely proportionalto soil resistivity. Lower electrical resistivities result from higher moisture and soluble salt contents and indicate corrosive soil. A correlation between electrical resistivity and corrosivity toward ferrous metals is:2 Soil Resistivity in ohm-centimeters Corrosivity Category Greater than 10,000 2,001 to 10,000 1,001 to 2,000 0 to 1,000 Mildly Corrosive Moderately Corrosive Corrosive Severely Corrosive Other soil characteristics that may influence corrosivity towards metals are pH, soluble salt content, soiltypes, aeration, anaerobic conditions, and site drainage. Electrical resistivities were in the corrosive and moderately corrosive categories with as- received moisture. When saturated, the resistivities were in the severely corrosive to corrosive categories. Some as-received resistivities were at or near their saturated values 1 Amerícan Publ¡c Health Association (APHA). 2012. Standard Methods of Water and Wastewater. 22nd ed.

This range is neutral.3 These values do not particularly increase soil corrosivity. The soluble salt content of the samples were low. Chloride and sulfate were found at low concentrations. Ammonium was detected in one sample at low concentration. Nitrate was detected in all samples with one sample concentration high enough to be aggressive to copper. Tests were not made for sulfide and oxidation-reduction (redox) potential because these samples did not exhibit characteristics typically associated with anaerobic conditions. This soil is classified as severely corrosive to ferrous metals and aggressive to copper Corrosion Control Recommendations The life of buried materials depends on thickness, strength, loads, construction details, soil moisture, etc., in addition to soilcorrosivity, and is, therefore, difficultto predict. Of more practical value are corrosion control methods that will increase the life of materials that would be subject to significant corrosion. The following recommendations are based on the soil conditions discussed in the Soil Corrosivity section above. Unless othen¡rise indicated, these recommendations apply to the entire site or alignment. Steel Pipe 1. Underground steel pipe with rubber gasketed, mechanical, grooved end, or other nonconductive type joints should be bonded for electrical continuity.

Where metallic pipelines penetrate concrete structures such as building floors, vault walls, and thrust blocks use plastic sleeves, rubber seals, or other dielectric materialto prevent pipe contact with the concrete and reinforcing steel. Eqnru SvsrEøs PActFtc HDR #19-0663SCS Qctober 16, 2019 Page 9 Concrete Structures and Pipe 1. From a corrosion standpoint, any type of ASTM C150 cement may be used for concrete structures and pipe because the sulfate concentration is negligible, from 0 to 0.10 percent.a,s'6 2. Standard concrete cover over reinforcing steel may be used for concrete structures and pipe in contact with these soils due to the low chloride concentrationsT found onsite. Limit the water-soluble chloride ion content in the concrete mix design to less than 0.3 percent by weight of cement. 3. Due to the high groundwater table encountered at this site, cyclical or continual wetting may be an issue. Any contact between concrete structures and groundwater should be prevented. a. For structures that extend below the water table, contact can be prevented with an impermeable waterproofing system. Options include a membrane such as Grace PrePrufeo products, a liquid applied barrier coating, or a waterproofing admixture such as Xypexo Admix. Visqueen, similar rolled barriers, or bentonite-based membranes are not viable waterproofing systems for corrosion protection. b. For structures above the water table, contact can be prevented with a gravel capillary break under the concrete and a vapor retarding membrane. Note that per ASTM 81643, "vapor retarders are not intended to provide a waterproofing function." I Alternatively, an impermeable waterproofing system may be used. a 20lS lnternational Building Code (IBC) which refers to American Concrete lnst¡tute (ACI) 318-14 Table 19.3.2.1 5 2015 lnternational Residential Code (IRC) wh¡ch refers to Amer¡can Concrete tnstitute (ACt) 315-14 Table 19.3.2.1 6 2016 Cat¡forn¡a Building Code (CBC) which refers to American Concrete lnst¡tute (ACI) 318-14 Table 19.3.2.1 7 Des¡gn Manual 303: Concrete Cylinder Pipe.

Concrete should be placed ín caisson excavations by means of a tremie pipe when the depth of water in the excavation cannot be limited to a maximum of 3 inches, and/or inflow less than L-inch in 5 minutes, per FHWA, or when the freefall of the concrete would result in the concrete striking the rebar or excavatíon walls as it falls. 2. The concrete should be pumped to the tremie pipe. Alternately, a hopper with a tremíe pipe attached should be used if approved by the architect/engineer. An "elephant's trunk" should not be used to place concrete under water; however, an elephant's trunk may be used to direct the fall of the concrete in dry excavations. The elephant's trunk should be of sufficient length to prevent the concrete from striking the rebar or excavation walls as it falls. 3. Concrete for dry excavations should be designed for, and placed at, a slump of 6 to 8 inches. Concrete to be placed below water should be designed and placed as a "flowable" mix with a minimum slump of 8 to 10 inches or should be designed and placed as "self-consolidating concrete." Suitability of high slump (to 78 inches) concrete should be verified by slump flow, slump flow velocity and visual stability testing. 4. The tremie pipe should consist of rigid steel pipe segments with waterproof joints. Gravity tremie pipes should be 6 inches in diameter or at least 6 times the maximum concrete aggregate size (whichever is greater) and should be longer than the deepest caisson excavation. Pressurized tremie systems (pump lines) may be smaller than 6 inches to accommodate rebar spacing or other factors. 5. The tremie pipe should be lowered with caution through the center of the reinforcing to within 1-foot of the bottom of the excavation; however, the tremie pipe should not be allowed to penetrate into the muck on the bottom of the hole. 6. The pump hose and tremie pipe should be "slicked" with Portland cement slurry. No clay, bentonite, or other material should be used unless approved by the architect/engineer and geotechnical engineer. 7 . Pumping of the concrete should begin immediately after the reinforcing and the tremie pipe have been placed in the excavation and the excavation and reinforcíng have been inspected. The tremie pipe should not be raised until the concrete surface in the caisson excavation is at least 5 feet above the bottom of the tremie pipe. The bottom of the tremie pipe should then be kept at least 5 feet below the top of the concrete until the pour is completed. 8. The concrete should be pumped until all muck, laitance, and unsuitable concrete has been lifted above the top-of-caisson elevation. All muck, laitance, and unsuitable concrete should be immediately removed from the excavation. 9. Self-consolidating concrete need not be víbrated during the pour, unless directed by the architect/engineer. For other than self-consolidating concrete, vibration should notbe started until the concrete pour is completed and the muck, laitance and unsuitable concrete have been removed. Then, only the upper 5 to L0 feet of the concrete should then be vibrated. Additional concrete may be added as necessary during vibration. The vibrator should not be allowed to contact the reinforcing. 10. During the pour, if the tremie pipe has to be removed from the concrete, (e.g., to allow removal of casing), it should be reset at the top of the concrete. The tremie should then be purged as directed by the inspector, and then immediately lowered to at least 5 feet below the top of the concrete as the concrete is being pumped. All degraded concrete should be lifted with the continuing pour and removed from the top of the caisson. 1,t. For a more thorough and in-depth discussion and recommendations on th¡s topic, please refer to "Guide to Tremie Concrete for Deep Foundations" by the Joint EFFC/DFI Concrete Task Group (Second Edition - 2018) available at http://www.dfi.orglV|EWPUB.ASP?tid=CPF-2015-DRSH-1. 12. Unless unavoidable due to equipment or supply breakdown, all caisson excavations should be filled with concrete on the same day they are drilled.

This requirement can be scaled back if minimal requests are received. I have so far only received one request for salvaging facilities, and I’ve attached that email. One thing not identified is hazardous materials, which we should not offer for salvage, unless there is a release of liability. I am hopeful that this is the only request received, but we may receive more. I’ll let others respond to the other items.
