RE: Murray Adobe Recommendations for Phase 1 of the Mission Plaza Concept Plan Dear Mr. Nelson:

At the request of RRM Design Group, Applied EarthWorks, Inc. (Æ) is pleased to present the following recommendations for appropriate treatment of the Murray Adobe during implementation of Phase 1 of the Mission Plaza Concept Plan (Plan). Phase 1 of the Plan includes removal of the trellis adjacent to the adobe, removal and replacement of landscaping and hardscaping, and extending the existing patio along the southwest wall to the southeast. Other actions include removal of existing public restrooms, planters, mature trees, and hardscape near Murray Adobe within Mission Plaza; construction of new public restrooms; and installation of new hardscape, planters, and trees. Murray Adobe is on the City of San Luis Obispo Master List of Historic Resources and is considered a historical resource under the California Environmental Quality Act (CEQA). Projects that are consistent with the Secretary of the Interior’s (SOI) Standards will not result in a significant impact under CEQA.

On December 20, 2022, Æ Senior Architectural Historian Amber Long met with Mark Sauer, owner of Mark Sauer Construction, Debbie Rudd, Principal at RRM Design Group, and representatives from the City of San Luis Obispo (City) in Mission Plaza to tour Murray Adobe. During the site visit Mr. Sauer visually inspected the interior and exterior of the adobe, while discussing the project with the team. Mr.

Sauer has worked extensively with historic adobe buildings around California and has successfully implemented protection measures that have been successful over decades of monitoring.

The following information is summarized from Mr. Sauer’s report and subsequent email (see attached).

All recommendations are consistent with the SOI Standards for the Treatment of Historic Places (Grimmer 2017).

Existing Condition
The adobe is in fairly good condition except for the exposed adobe wall. The existing cement-based plaster is not the correct application for the adobe. Adobe bricks expand and contract, while the cementbased plaster is rigid, which can create structural issues. Sections of the plaster are delaminating from the interior and exterior of the adobe.

Phase 1 Recommendations. The following recommendations should be followed during Phase 1 of the Plan.
• Demolition of the pavement adjacent to the adobe should start with a cut 3 to 4 feet away from the exposed adobe. The pavement will then be removed by hand, limiting the potential for damage to the adobe. Where new paving will abut the adobe, some form of masonry protection

2 Murray Adobe Recommendations for Phase 1 of the Mission Plaza Concept Plan board should be installed. This process should also be followed where the patio will be extended along the adobe, to the southeast.
• The existing flashing, trellis, and patio cover can be removed. A new ledger should be installed directly to the adobe wall using epoxy anchors and should support a small patio cover over the exposed adobe wall. A structural engineer should be consulted regarding the size, depth, and frequency of the anchors.
• Existing plaster should be cut away to allow direct anchoring of the ledger to the adobe wall.

Enough plaster should be removed so the top of the new flashing is covered. Copper flashing is preferable. Expanded metal lath with 3-inch exterior grade screws and fender washers are recommended. Plaster around the ledger and new flashing will need to be repaired. New lime plaster should not contain cement.
• The exposed area of the adobe wall should be reduced to a 3 by 3 foot area. The area will be used as a view panel with a wood frame and laminate glass. The remaining exposed adobe should be covered in lime plaster. New lime plaster should not contain cement.

Recommendations for Additional Work. After completion of Phase 1, the following recommendations should be followed to address ongoing condition issues. • All cement-based plaster should be removed from the interior and exterior adobe walls and a new lime-based plaster applied. Additional information can be found at www.limes.us. • Proper site drainage is critical to preserving Murray Adobe. All mulch should be removed within 12 to 18 inches of the adobe walls. Irrigation must be altered so that no water hits the walls or pools at the base of the walls. Based on the direction of the slope, water will continue to flow from Mission San Luis Obispo de Tolosa towards the adobe to San Luis Creek. French drains could be installed to route the flow of water around the adobe. • All existing wood windows need repairs. Windows can be salvaged by repairing the glass and glazing. Wood repairs should include “dutchman” repairs and the addition of wood consolidating products. Additional information can be found at www.abatron.com. • The roof needs to be replaced; however, it is currently holding out water. A new roof will require new ply sheathing.
• A seismic retrofit should be considered for the adobe as part of a structural upgrade.

Secretary of the Interior’s Standards
Until a new use is proposed for Murray Adobe, the SOI Standard for Preservation should be followed to preserve the adobe in its current configuration. The recommendations above, including proper lime plaster coatings, reducing the exposed area of the adobe, improving drainage and window repairs, are consistent with the Standard for Preservation, which is:

3 Murray Adobe Recommendations for Phase 1 of the Mission Plaza Concept Plan “… the act or process of applying measures necessary to sustain existing form, integrity, and materials of an historic property. Work, including preliminary measures to protect and stabilize the property, generally focuses upon the ongoing maintenance and repair of historic materials and features rather than extensive replacements and new construction.” (Grimmer 2017:2) The following National Park Service Preservation Briefs and Preservation Tech Notes provide further guidance on the recommendations above. They can be found at www.nps.gov. • Preservation Brief 4: Roofing for Historic Buildings ((Sweetser 1978) • Preservation Brief 5: The Preservation of Historic Adobe Buildings ((Tiller and Look 1978) • Preservation Brief 9: The Repair of Historic Wooden Windows (Myers 1981) • Preservation Brief 10: Exterior Paint Problems on Historic Woodwork (Weeks and Look 1982) • Preservation Brief 41: The Seismic Rehabilitation of Historic Buildings (Aguilar 2016) • Temporary Protection 3: Protecting a Historic Structure During Adjacent Construction (Randl 2001)
• Windows 1: Planning Approaches to Window Preservation (Fisher 1984) • Windows 4: Replacement Wooden Frames and Sashes (Feist 1984) • Windows 14: Reinforcing Deteriorated Wooden Windows (Stumes 1986) The preceding recommendations are intended to limit or eliminate any unintended damage to Murray Adobe from implementation of Phase 1 of the Plan. In the event of unintended damage, including but not limited to new cracking or chipping plaster, or crumbling adobe bricks, work in the area around Murray Adobe should stop and a structural engineer and/or adobe specialist consulted.

Æ appreciates the opportunity to provide this guidance. If you have further questions, please contact Managing Principal Erin Enright at (805) 594-1590, extension 316, or [email protected].

Sorry I overlooked that part. I envision something like this.

Incorporated into the new or reworked wood patio cover/trellis a new or added 4x (or greater) ledger can be installed. This ledger should be treated lumber. The ledger can be anchored to the adobe wall using epoxy anchors. A structural engineer should be consulted to recommend the size, depth and frequency of these anchors. The anchors will be placed either horizontally or at a 22-degree angle. This will also be per the engineer’s recommendations.

Were the new ledger is installed the existing plaster needs to be cut away and the ledger installed directly to the adobe wall. Enough plaster needs to be removed so the top vertical leg of the new flashing (preferably copper) gets covered. Expanded metal lath should be used in the repair area. Install lath with 3” exterior grade screws with fender washers. Please see my simple sketch.

Plaster will need to be repaired all around the new ledger.

If the exiting patio cover/trellis is to remain and new “ledger” can be installed above the existing following the same procedure.

Introduction
Archaeological Monitoring Plan 3
1 Introduction
Rincon Consultants, Inc. (Rincon) was retained by the City of San Luis Obispo (City) to provide an Archaeological Monitoring Plan (AMP) in support of the Mission Plaza Restroom and Kiosk Project (project) in San Luis Obispo, California. The AMP will address the details, timing, and responsibility of the required Conditions of Approval (CoA) for archaeological monitoring activities.

The City proposes to construct a 504 square foot restroom and a 165 square foot kiosk within Mission Plaza in San Luis Obispo, California. The proposed project would include demolition of the existing site structures, utilities, and select trees and landscaping within the project site. Proposed construction activities include the addition of plaza and patio space, a bar seating area, a reconstructed restroom, and a digital art kiosk. The project will also include new site utilities and landscaping.

This Archaeological Monitoring Plan (AMP) was prepared by Rincon Consultants, Inc. (Rincon) in accordance with the Conditions of Approval: ARCH-0052-2022 (989 Chorro) established by the City of San Luis Obispo Public Works Department on June 1, 2022. The purpose of this AMP is to outline the procedures and protocols for archaeological monitoring.

Archaeological Monitoring
CoA ARCH-0052-2022 states that the applicant shall provide an archaeological monitoring plan prepared by a City -qualified archaeologist to be implemented during construction. The plan shall identify the qualified professional who will conduct the monitoring and circumstances where a Native American tribal representative or qualified site monitor is required. The plan shall recommend specific procedures for responding to the discovery of archaeological resources during the construction of the project consistent with Section 4.60 of the Archaeological Resources Preservation Program Guidelines (ARPPG). The plan shall be submitted as a part of the building permit (CoA-3 2022).

This document outlines the steps to be taken during unanticipated discoveries to mitigate potential significant impacts, determining when Native American monitoring would become necessary, if it all, and provides methods for determining if and when monitoring may be reduced or eliminated during the course of project execution.

Project Location and Description
Situated between Mission San Luis Obispo de Tolosa (mission) San Luis Obispo Creek (creek), Mission Plaza is located centrally in downtown San Luis Obispo. It encompasses two bridges, a public restroom building, and the historic Murray Adobe (P-40-040036/contributing resource to the San Luis Obispo Downtown Historic District). The Mission Plaza project site is located within Township 30 South, Range 12 East, Sections 26 and 35 as depicted on the San Luis Obispo, California United States Geological Survey (USGS) 7.5-minute topographic map (Figure 1). The project site is south of Mission San Luis Obispo de Tolosa, north of San Luis Obispo Creek, east of Broad Street, and west of Chorro Street (Figure 2).

The City proposes to construct a 504 square foot restroom and a 165 square foot kiosk within Mission Plaza (Plaza). The proposed project would involve the demolition of the existing facilities,

City of San Luis Obispo
Mission Plaza Restroom and Kiosk Project
4 excluding the Murray Adobe. This would include the removal of the restroom building, trellis structure, stone walls, curbs, gutters, sidewalks, existing utilities, and select trees and landscaping within the project site.

The new restroom building will be located southwest of the current restroom building and the kiosk will be located between the Murray Adobe and the new restroom building. A new patio area will be developed in a location consistent with the current patio west of Murray Adobe. The new patio area will be connected to the new restroom building via a set of steps and Americans with Disabilities Act (ADA)- compliant ramp. Following construction of the new restroom building, kiosk, and bar, new hardscaping consisting of pavers laid in a star pattern, landscaping and features to support public use, such as benches, lighting, and drinking fountains, will be installed throughout the project site.

Introduction
Archaeological Monitoring Plan 5

4.60.3. Mitigation
If significant archaeological resources are present, the archaeologist shall propose specific mitigation measures in writing. The Community Development Director (Director) may approve, approve with changes or reject the mitigation proposal. The project applicant shall implement the proposal, to the satisfaction of the Director. A copy of the archaeologist's recommendations and the Director's decision will be forwarded to the Cultural Heritage Committed (CHC), (City of San Luis Obispo 2009).

Cultural Resource Sensitivity
Cultural Background
The project site is within a known archaeological site (CA-SLO-2341H), as well as the City’s Downtown Historic District, and adjacent to Mission San Luis Obispo de Tolosa (CA-SLO-64/H). The City’s Archaeological Resource Preservation Program Guidelines (ARPPG) define archaeologically sensitive areas as those locations inside or within 200 feet of the boundaries of a known archaeological site; properties within 200 feet of the top of banks of major creeks; and areas inside a designated Historical District as shown on archaeological sensitivity maps on file at the Community Development Department (City of San Luis Obispo 2009).

Rincon understands a categorical exemption was conducted for the project and there were Conditions of Approval for the building permit. The current project is located in the City of San Luis Obispo in close proximity to the Mission San Luis Obispo de Tolosa and approximately 11 meters north of the San Luis Obispo Creek. The presence of recorded archaeological resources and proximity of historical buildings increases the likelihood of encountering historic-period archaeological deposits within the project site. The presence of subsurface deposits is also suspected according to recent studies performed by Applied Earthworks (2020). Given the project is within areas determined to be sensitive for archaeological resources the CoAs is requiring archaeological monitoring during construction.

CA-SLO-2341H
Sie CA-SLO-2341H represents the Mission Plaza and the Historic Downtown District. Both of these historic built environments are located in and/or near a sensitive archaeological (prehistoric and historic) resources area. The area consists of multiple subsurface Mission and historic-period refuse/trash pits. Examinations of these pits have identified various types and kinds of colored and uncolored glass objects (intact and fragments), cooking utensils, porcelain (fragments), ceramic roofing titles (intact and fragments), and wire nails. The Mission Plaza and the Historic Downtown District are on the City of San Luis Obispo Master List of Historic Resources and is considered a historical resource under the California Environmental Quality Act (CEQA). Given the sensitivity of the area, past work in proximity to CA-SLO-2341H has required monitoring. Most recently, Applied Earthworks, Inc. completed an Archaeological Monitoring Plan for the project in April 2020 (Wathen and Long 2020). The plan identified one historic-period archaeological resource (CA-SLO-2341H) mapped within the project site.

San Luis Obispo Downtown Historic District
In addition to CA-SLO-2341H, the Applied Earthworks plan further identified that the project site lies within the locally designated San Luis Obispo Downtown Historic District, which includes many of

City of San Luis Obispo
Mission Plaza Restroom and Kiosk Project
6 the City’s most important historic buildings with a variety of architectural styles (Wathen and Long 2020). Within the Historic District are Mission San Luis Obispo and Murray Adobe. The Murry Adobe, erected by Walter Murray in 1850, was used to store the Tribune newspaper's printing press. The Murray Adobe is situated roughly 30 meters north of the planned new restrooms. Despite undergoing multiple alterations since its construction, the adobe now represents only a fraction of its original structure. Nevertheless, it has undergone restoration efforts to return it to its initial design (Wathen and Long 2020). The Murray Adobe is on the City of San Luis Obispo Master List of Historic Resources and is considered a historical resource under the California Environmental Quality Act (CEQA).

CA-SLO-64/H
Resource CA-SLO-64/H encompasses a significant historical area, including the Mission San Luis Obispo de Tolosa and associated archaeological deposits. This historic resource encapsulates remnants and features linked to the mission itself, as well as historical traces of Native American and Chinese occupations. Additionally, it includes deposits from the Victorian era that are spread across a considerable area along Higuera, Monterey, and Palm streets. This designation highlights the rich and diverse historical layers present in the vicinity (Wathen and Long 2020).

Monitoring Procedures
Archaeological Monitoring Plan 7
2 Monitoring Procedures
Archaeological Construction Monitoring
Requirements
In accordance with CoA-3, archaeological monitoring is required for all project-related ground disturbance. Archaeological monitoring efforts shall be conducted under the direction of a Cityqualified archaeologist who meets the Secretary of the Interior’s Professional Qualifications Standards for prehistoric and historic archaeology (National Park Service [NPS] 1983; hereafter, Qualified Archaeologist). The monitoring methods provided in this plan are designed to comply not only with CoA-3, but also remain consistent with the City’s ARPPG-4.60-1, 4.60-2, and 4.60-3 (City of San Luis Obispo 2009).

Archeological Monitoring Duties
An archaeological monitor shall be onsite during project-related earthmoving activities.

Earthmoving activities include, but are not limited to, vegetation removal, grading, boring, excavation, trenching, and all other excavation activities. During monitoring, the monitor(s) 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, housewares, ceramics, construction materials), and/or soil discoloration that might indicate an archaeological deposit or feature, as specified in ARPPG-4.60-1, 4.60-2, and 4.60-3 (City of San Luis Obispo 2009).

Daily Archaeological Monitoring Log
The archaeological 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. The monitoring forms shall be submitted to the City as an attachment to the archaeological construction monitoring report
Archaeological Construction Monitoring Report
The qualified archaeologist will prepare an Archaeological Construction Monitoring Report (ACMR) that will outline the methods and results of the archaeological construction monitoring effort. The report will include maps, photographs and will include the daily monitoring logs completed by the construction archaeological monitor (City of San Luis Obispo 2009).

Unanticipated Discovery of Cultural Resources
In the event of anticipated discovery of cultural (prehistoric or historic) resources the archaeological 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. If the archaeological resource is prehistoric in nature, a local Native American group will be contacted and given the opportunity consult with the City regarding the find and provide recommendations. A Native American monitor will be retained for the remainder of earth disturbing activities should a

City of San Luis Obispo
Mission Plaza Restroom and Kiosk Project
8 prehistoric resource be found during construction (City of San Luis Obispo 2009). Recovery protocols in the case of a find are discussed in greater detail in Section 3 below.

2.1.5 Duration of Archaeological Monitoring
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. In accordance with CoA-3 and ARPPG-3, 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 (City of San Luis Obispo 2009).

Archaeological Resources Discovery Plan
Archaeological Monitoring Plan 9
3 Archaeological Resources Discovery
Plan
The following outlines the procedures to be followed in the inadvertent discovery of cultural resources, including human remains.

Discovery of Archaeological Resources
In accordance of CoA-3 and ARPPG, the procedure for appropriately evaluating unanticipated resources encountered during construction will include, but not be limited to, the following:

For the discovery of previously unknown archaeological (prehistoric or historic) 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 archaeological monitor will report the discovery to the 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 be contacted to consult about the find, and a Native American monitor will be retained for the remainder of earth disturbing activities (City of San Luis Obispo 2009).

Upon completion of the above notification, the archaeological monitor will determine the nature and extent of the archaeological 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 a single isolated artifact, the monitor will immediately notify the qualified archaeologist, the City, and construction superintendent that activities may resume as soon as the archaeological item(s) has been properly photographed and recorded (City of San Luis Obispo 2009).

If potentially significant cultural features, artifact concentrations, or intact deposits are discovered, the archaeological monitor will divert construction activities away from the find and report the discovery to the qualified archaeologist, the City, and the construction superintendent, so that appropriate notifications to the City can be issued (City of San Luis Obispo 2009).

A temporary Construction Exclusion Zone (CEZ), consisting of lath and flagging tape, will be erected around the discovery. A radius of 50 feet may be established so that the resource may be evaluated.

However, 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, and for safety (City of San Luis Obispo 2009).

A minimum 50-foot radius shall also be established for any remains that are suspected of being human (see Section 3.2 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. The CEZ will not be removed until the potentially significant cultural resource has been evaluated to assess whether it is considered 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, the qualified archaeologist will immediately contact the City to formulate a plan for further treatment. If necessary, the evaluation may require archaeological testing for California Register of Historical Resources (CRHR) eligibility. If the discovery proves to be eligible for the CRHR and cannot be avoided by the modified project, additional work, such as data

City of San Luis Obispo
Mission Plaza Restroom and Kiosk Project
10 recovery excavation, may be warranted to mitigate any significant impacts to historical resources (City of San Luis Obispo 2009).

Archaeological (prehistoric or historic) resources identified within the site shall be recorded according to current archaeological standards (California Office of Historic Preservation 1990) and in compliance with City Guidelines (City of San Luis Obispo 2009). 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 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 4.1 below. If the report discusses archaeological resources, it will be considered confidential (City of San Luis Obispo 2009).

Discovery of Human Remains
There is a possibility that the project’s construction-related activities may encounter human remains. Therefore, in accordance with CoA-3 and 4.40.3.2, if the project’s construction-related activities find potential human bone or remains, ground-disturbing activities in the area of the discovery shall immediately be halted and redirected while a temporary CEZ surrounding the site of discovery is established to allow for further examination and treatment of the find (City of San Luis Obispo 2009). 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.

Reporting of Monitoring Results and Curation Finds
Archaeological Monitoring Plan 11
4 Reporting of Monitoring Results and
Curation Finds
Reporting of Archaeological Monitoring Results
At the conclusion of the monitoring effort, the Archaeological Monitoring Plan (AMP) will be prepared under the direction of the qualified archaeologist. The monitoring report will outline the monitoring methods employed, 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 (City of San Luis Obispo 2009).

If archaeological materials are identified, a comprehensive technical report will 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 and City Guidelines (California Office of Historic Preservation 1990 and City of San Luis Obispo 2009). If required, the ARMR-format report shall include a complete description of resources identified during monitoring, treatment of those resources, California Register for Historic Resources (CHHR) eligibility recommendations, site records, and site maps. If the report discusses archaeological resources, it will be considered confidential (City of San Luis Obispo 2009).

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 the qualified archaeologist at a secured off-site laboratory, until either an appropriate on-site reburial location not subject to future ground disturbance or repository is agreed upon by the City, other interested Native American groups, and/or MLD.

If the qualified archaeologist, in consultation with the Native American representative (if applicable), and the City, is unable to bury newly discovered isolated artifacts within the project boundaries, the qualified archaeologist will secure a written agreement with a recognized museum repository or comparable institution that meets the State of California Guidelines for the Curation of Archaeological Collections (National Park Service 1993) such as the Repository for Archaeological and Ethnographic Collections at the University of California, Santa Barbara, or San Luis Obispo County Archaeological Society (SLOCAS) Collections regarding the final disposition, permanent storage, and maintenance of any archaeological resources discovered during archaeological monitoring and determined not to be ceremonial and/or cultural artifacts.

Permanent treatment of human remains and associated funerary items shall be determined by the City in consultation with the MLD (City of San Luis Obispo 2009).

3 EXECUTIVE SUMMARY
MATERIALS WHICH CONTAIN ASBESTOS:

No asbestos containing materials were identified.

SUSPECT MATERIALS WHICH NO ASBESTOS WAS DETECTED:

Plaster located on the interior walls was sampled and no asbestos was detected in any of the samples.

Cementitious Coating located on the exterior walls was sampled and no asbestos was detected in any of the samples.

Concrete Slab was sampled and no asbestos was detected.

Tar/Felt located on the roof (under tile) was sampled and no asbestos was detected.

FINDINGS
West Coast Safety Consultants collected samples of each suspect asbestos containing building material (ACBM) encountered at the specific site location. The Environmental Protection Agency (EPA) sampling protocol was utilized which requires multiple samples of suspect asbestos containing materials which are applied by spraying or troweling. A total of six samples were submitted to SGS Forensic Laboratories, an EPA accredited laboratory for analytical testing. Laboratory results are found in appendix C of this report. The samples were analyzed for the presence of asbestos by Polarized Light Microscopy (PLM) with dispersion staining in accordance with the EPA Method 600/R-93-116, Visual Area Estimation.

Of the six samples that were analyzed for asbestos, none were found to contain asbestos. No other asbestos containing materials were identified.

CONCLUSIONS AND RECOMMENDATIONS
No asbestos containing materials were identified on the inspection. If additional suspect materials are discovered during demolition or renovation activities, the material should be assumed to contain asbestos until sampling proves otherwise.

The San Luis Obispo County Air Pollution Control District is delegated authority to implement the asbestos NESHAP regulation in San Luis Obispo County. This regulation requires specific actions by the Owner or Operator of applicable projects. Before you begin your project and for further information, please visit their web site at: https://www.slocleanair.org/rules-regulations/asbestos.php or call the Engineering and Compliance Division at (805) 781-5912.

These conclusions and recommendations are based on the requirements set forth in 40 CFR Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAP), and Title 8, Chapter 4, Paragraph 1529, the Asbestos Standard of the California Occupational Safety and Health Administration.

CLOSURE
The findings and conclusions rendered in this report are opinions based on the scope of work authorized by the client and laboratory analysis of building material samples collected during this inspection. This report does not reflect variations which may exist between sampling points. These variations cannot be anticipated, nor could they be entirely accounted for, in spite of exhaustive additional testing. Our work has been performed in accordance with generally accepted practices in the field of asbestos consultation. No other warranty, either expressed or implied is made.

WEST COAST SAFETY CONSULTANTS

4 Although every effort is made to identify all the asbestos containing materials in a building, it is possible for asbestos containing materials which are located under sub-floors, behind walls or otherwise hidden from view to go undetected until demolition or renovation activities uncover the material. If additional suspect materials are discovered, West Coast Safety Consultants will collect samples and provide a report for no additional cost other than the laboratory fee for sample analysis.

Enclosed with this report is a sample result summary, sample location diagram, a laboratory report from SGS Forensic Laboratories and a copy of my asbestos certificate. I appreciate this opportunity to be of service. Should you have any questions or comments regarding this report, please contact this office at your convenience.

RE: Lead Building Inspection – 751 Palm Street, San Luis Obispo, California

INTRODUCTION
This report presents the findings of West Coast Safety Consultants inspection for lead containing materials at the Mission Plaza Restroom located at 751 Palm Street, San Luis Obispo, California on June 23, 2023. The inspection was conducted for CAL-OSHA and EPA compliance in conjunction with the renovation/demolition of the building. All accessible areas were visibly inspected and representative samples of suspect materials were obtained and analyzed.

Samples were not collected from every painted surface, however samples were obtained which represent the majority of the painted surfaces at the specific site location.

LEAD SAMPLE ANALYSIS
The survey involved a visual inspection of the building and sample collection from painted surfaces and ceramic tile. The samples were analyzed by SGS Forensic Laboratories using Flame Atomic Absorption in accordance with the Environmental Protection Agency (EPA) Method (3050B/7420) to identify lead content. SGS Forensic Laboratories is a laboratory which is certified to analyze for lead. They are accredited by the American Industrial Hygiene Association, the National Institute of Standards and Technology, and the California Department of Public Health (CDPH). Please note the attached laboratory report. 4581 Wavertree Street, San Luis Obispo, CA 93401 Phone (805) 748-8832

2 LEAD FINDINGS
West Coast Safety Consultants visual inspection identified that the painted surfaces were intact and in good condition. A total of seven samples were collected and analyzed for lead content.

The results in parts per million (ppm) are as follows:

Sample# Location Description Lead Content
RR-101 Interior Block Wall Beige Paint None Detected
RR-102 Exterior Block Wall Beige Paint None Detected
RR-103 Exterior Block Wall Beige Paint None Detected
RR-104 Exterior/Interior Window Frame Brown Paint None Detected RR-105 Exterior/Interior Door/Door Frame Brown Paint None Detected RR-106 Exterior Beam/Eave/Fascia Brown Paint 480 ppm
RR-107 Interior Wall Ceramic Tile None Detected
As a comparison, the EPA and CDPH consider a material to be lead based paint when it exceeds .5% or 5,000 ppm. In addition, the Consumer Product Safety Commission (CPSC) set a limit of .009% or 90 ppm of lead in paint for children’s toys and CAL-OSHA regulates workers who disturb lead coated surfaces at any detectable lead level.

SUMMARY
No lead was detected in the samples collected from the following building components:

1. Interior/Exterior Painted Walls

2. Interior Ceramic Tiled Walls

3. Interior/Exterior Painted Window Frames

4. Interior/Exterior Painted Door/Door Frame
A low level of lead (480 ppm) was detected in the sample collected from the painted exterior beams/eaves/fascia.

WEST COAST SAFETY CONSULTANTS

3 West Coast Safety Consultants recommends any contractor conducting work which will disturb painted surfaces or ceramic tile receive notification of the lead content and the condition of the lead containing surfaces prior to demolition, renovation, or any activity which would disturb the material. All work should be conducted in compliance with the CAL-OSHA and EPA regulations.

CLOSURE
The findings and conclusions rendered in this report are based on the scope of work authorized by the client and laboratory analysis of building material samples collected during this inspection. This report does not reflect variations which may exist between sampling points.

These variations cannot be anticipated, nor could they be entirely accounted for even with exhaustive testing. All work has been performed in accordance with generally accepted practices in the field of lead consultation.

The conclusions and recommendations listed in this report are based on the Department of Housing and Urban Development Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, 40 CFR Part 61, National Emission Standards for Hazardous Air Pollutants (NESHAP), and Section 1532.1 the Lead Standard of the California Occupational Safety and Health Administration.

I have enclosed the required CDPH Notification of a Lead Inspection, a laboratory report from SGS Forensic Laboratories, a sample location diagram and a copy of my lead credentials. If you have any questions, please contact me at 805-748-8832. Thank you for choosing West Coast Safety Consultants.

1.0 INTRODUCTION AND SITE SETTING
Based on preliminary project plans provided by RRM design group, the proposed improvement project will consist of the removal of the existing restroom and the construction of a new restroom and café in the San Luis Obispo Mission Plaza. We understand that the café will be approximately 165 square feet and be of wood or steel framed construction. The restroom structure will be approximately 470 square feet and will be of masonry construction. Additional improvements will consist of pedestrian flatwork, underground utilities, and landscaping. There will be no retaining walls, subterranean structures, or infiltration facilities.

We understand the restroom structure will be supported on conventional continuous and spread footings, and the café will be supported on pole foundations. We have estimated dead plus live loads, to be on the order of 2 kips per linear foot and 25 kips for wall and column loads, respectively. Further, the structures will have a relatively short period; and therefore, seismic design criteria using the general ground motion procedure outlined in ASCE 7‐16 Sections 11.4.2 through 11.4.5 is provided. Other site improvements will include addition and relocation of underground utilities, exterior pedestrian flatwork, and vehicular pavement.

The site is located in the west portion of the San Luis Obispo Mission Plaza, as shown in Figure 1 – Exploration Location Map in Appendix A. A restroom structure, pedestrian flatwork and several trees currently occupy the project site. The undeveloped portion of the site is covered in grasses.

The location of the café structure is relatively flat. The location of the new restroom is relatively flat toward the north then slopes drastically downward toward San Luis Obispo Creek to the south. Grading for the project is expected to include cuts and fills up to 2 feet. The approximate site coordinates from the Google Earth website (Google 2022) are latitude 35.2800 degrees north and longitude 120.66.45 degrees west.

2.0 SCOPE OF SERVICES
The scope of work for this geotechnical engineering investigation included the following: a general site reconnaissance, subsurface exploration, laboratory testing of selected samples, geotechnical evaluation of the data collected, and the preparation of this report.

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, grading, utility trenches, foundations, interior slabs-on-grade and exterior pedestrian flatwork, drainage and maintenance, and observation and testing are presented to guide the development of project plans and specifications. As there may be geotechnical issues yet to be resolved, the geotechnical engineer should 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.

It is our intent that this report be used exclusively by the client to form the geotechnical basis of the design of the project and in the preparation of plans and specifications. Application beyond this intent is strictly at the user’s risk.

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 aerial or site geology, or of the soil for corrosivity, 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. Any ancillary features such as flag or light poles, temporary access roads, and non-structural fills, or other improvements not addressed herein are not within our scope and are also not addressed.

In the event that there are any changes in the nature, design, or location of improvements, or if any assumptions used in the preparation of this report prove to be incorrect, the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed, and the conclusions of this report modified or verified by the geotechnical engineer in writing. 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 INVESTIGATION
Our geotechnical field investigation consisted of two exploratory borings drilled at the site on August 17, 2022 to depths ranging from approximately 11.0 to 11.5 feet below the existing ground surface (bgs). Borings were drilled with a truck-mounted Simco EP 200 drill rig that utilized a four-inch outside diameter solid stem auger with an automatic trip hammer for sampling. The approximate locations of the borings are shown on the Figure 2 - Exploration Location Map in Appendix A.

Soil samples were obtained from the exploratory borings using a 3-inch outside diameter ringlined barrel sampler D 3550 - 17 (with shoe similar to D 2937 - 17) and Standard Penetration Tests (SPT) were conducted at selected depths within the borings (ASTM D1586 -18). Bulk soil samples were also obtained from the auger cuttings. After sampling was complete, the borings were backfilled with the auger cuttings.

Soils encountered in the current borings were categorized and logged in general accordance with the Unified Soil Classification System and ASTM D 2488-17. Copies of the current boring 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 soil characteristics as observed during drilling. These include, but are not limited to, the presence of cobbles or boulders, cementation, variations in soil moisture, presence of groundwater, and other factors. Consequently, the logger must exercise judgment in interpreting the subsurface characteristics, possibly resulting in soil and bedrock descriptions that vary somewhat from the legend.

4.0 LABORATORY ANALYSIS
Selected samples from the current borings were tested in our laboratory for bulk density (ASTM D 2937-17, modified for ring liners) and moisture content (ASTM D 2216-16), maximum density and optimum moisture content (ASTM D 1557-12), grain size distribution by sieve analysis (ASTM D 1140-17), and cohesion and angle of shearing resistance (ASTM D 3080-11).

The geotechnical laboratory test results for our investigation are presented in Appendix B.

5.0 GENERAL SUBSURFACE PROFILE
Based upon our investigation, the site is underlain by alluvium. The alluvium consisted of layers of medium dense clayey sands and stiff to very stiff sandy lean claysto maximum depths explored of 14.0 to 16.5 feet bgs. Boring 2 was terminated at 14.0 feet due to refusal on cobbles. There was no subsurface water encountered during the exploration.

Please refer to the Boring Logs in Appendix A for a more detailed description of the subsurface conditions encountered in the subsurface investigations performed by this firm at the site.

6.0 CONCLUSIONS
In our opinion, the site is suitable, from a geotechnical engineering standpoint, for the restroom and café buildings discussed in the “Introduction and Site Setting” section of the report, provided the recommendations contained herein are implemented in the design and construction. In our opinion, the primary geotechnical engineering concerns at the site are the potential for strong seismic shaking and soil expansion potential. Total and differential settlement, soil erosion potential and liquefaction potential are also discussed below.

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. The CBC requires that seismic loads be considered in structural design. A seismic analysis was undertaken to provide seismic acceleration design parameters; the results are presented in the “Foundations” section of this report for use by others in the structural design process.

The 2010 ASCE 7 method with 2013 updates available on the Structural Engineers Associate of California (SEAOC) Seismic Design Map Tool website (SEAOC, 2021) was used for the seismic analysis. The risk category for buildings and structures is assigned by others in accordance with CBC Table 1604.5; however, based on our current understanding of the project, we selected Risk Category II for our analysis. Based upon the subsurface conditions encountered during our subsurface investigation, Site Class “D”, “Stiff Soil,” was used. A general ground motion seismic analysis was performed, assuming that Exception 2 listed in Section 11.4.8 (ASCE, 2017) will apply to the project. We also provided seismic parameters if the Simplified Lateral Force Analysis Procedure from Section 12.14.8 (ASCE, 2017) will be used in structural design.

Soil Expansion Potential
An expansion index test of the near-surface soils yielded a result of 33. Per Section 1803.5.3 of the 2019 CBC, soils are considered to be non-expansive for expansion index values of 20 or less and expansive for values higher than 20. Using the terminology typically associated with the ASTM test method for expansion, the soils are considered to have “low” 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, including moisture conditioning the soil, placement of non-expansive fill, and deepening foundations, are provided in the “Preliminary Geotechnical Recommendations” Section of this report.

Potential for Total and Differential Settlement
Settlement (total and differential) can occur when foundations and surface improvements span materials having variable consolidation, moisture, and density characteristics. Such a situation can stress and possibly damage foundations and surface improvements, often resulting in severe cracks and displacement. To reduce this settlement potential, it is necessary for all foundations and surface improvements to bear on material that is as uniform as practicable. A program of overexcavation, moisture conditioning, and compaction of the upper soils in the building and surface improvement areas is recommended to provide more uniform soil moisture and density and appropriate support.

Erosion Potential
The site soils are considered to be erodible. Caution should be exercised to protect the soil from erosion during and following construction.

Liquefaction Settlement
The site is mapped by the City of San Luis Obispo (2014) as being in an area of moderate liquefaction potential. However, due to the lack of subsurface water encountered in our borings and the clay content in the soils encountered, it is our opinion the potential for damage due to liquefaction at the site is very low.

7.0 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 Slab Area: The building slab area is defined as the area within and not including the perimeter of the proposed foundations.
• Flatwork Areas: The area within the limits of exterior pedestrian flatwork and extending a minimum of 1 foot beyond the perimeter of the proposed improvements. • Grading Area – The entire area to be graded, including building slab, foundation, and flatwork areas.
• Subgrade: The elevation of the surface upon which a sand cushion/non-expansive imported material or aggregate base will be placed for flatwork improvements. • 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 directions to a depth of not less than 8 inches.
• Moisture Conditioned: Soil moisture content adjusted to just 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.

Site Preparation

1. The ground surface in the grading area should be prepared for construction by removing existing improvements, 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 by the geotechnical engineer, as necessary.

2. Voids created by the removal of materials or utilities described above and extending below the recommended depth of overexcavation 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.

Grading

1. Following site preparation, soils within the building slab area should be removed to a level plane at a minimum depth of 1 foot below planned bottom-of-slab elevation. The exposed surfaces should then be scarified, moisture conditioned and recompacted.

2. Exterior pedestrian flatwork areas should be excavated to 1 foot below planned subgrade elevation or existing grade, whichever is deeper. The soi surface exposed by overexcavation should be scarified, moisture conditioned and recompacted.

3. Voids created by dislodging cobbles and/or debris during scarification should be backfilled and recompacted, and the dislodged materials should be removed from the work area.

4. Within the building slab area, all soils used as fill should be nonexpansive.

5. Nonexpansive soils are defined as falling into the GP, GW, GM, GC, SM, SC, SP, or SW categories (ASTM D 2487-17) and having an expansion index of 10 or less (ASTM D 4829- 21). Imported nonexpansive soils used in the building area should have strength qualities equal to or better than the site soils. All proposed imported fill should be approved by the geotechnical engineer before being transported to the site and periodically during construction. The clean sand layer described in the “Interior Slabs-on-Grade and Exterior Pedestrian Flatwork” Section of this report (if utilized) is considered to be part of the minimum recommended depth of nonexpansive material, not in addition to it.

Restroom and Café
305341-001 8 2210-071.SER

6. Previously removed site soils may be used as fill beyond the building slab area.

7. All materials used as fill should be cleaned of all debris and any rocks larger than 6 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.

8. If the soils become unstable, or if the recommended compaction cannot be readily achieved, drying the soil to just above optimum moisture content 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.

Utility Trenches

1. 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 D.

2. 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.

3. A select, noncorrosive, easily compacted sand should be used as bedding and shading immediately around utilities. All trench backfill, within the upper 12 inches of the building areas should be nonexpansive. Site soils or select import may be used as trench backfill within the remaining trench depths.

4. Utility trench backfill should be moisture conditioned and compacted to a minimum of 90 percent of maximum dry density. Trenches located within areas subject to vehicle loading should be compacted to a minimum of 95 percent of maximum dry density within the upper foot of subgrade and all aggregate base.

5. Trench backfill should be placed in level lifts not exceeding 6 inches in loose thickness, moisture conditioned, and compacted to the minimums noted above.

City of SLO – Mission Plaza October 21, 2022
Restroom and Café
305341-001 9 2210-071.SER

6. 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.

7. The recommendations of this section are minimums only, and may be superseded by the requirements of the architect/engineer, the recommendations of the pipe manufacturers or utility companies, or the requirements of the governing jurisdiction based upon soil corrosivity or other factors.

Foundations
Shallow Foundations

1. Conventional continuous and spread footings bearing in firm, native soils should be utilized to support the restroom structure. The footings should be constructed at a minimum overall depth of 30 inches below finished grade. The full perimeter of the structure should be supported by footings or grade beams. Footing reinforcement should be in accordance with the requirements of the architect/engineer.

2. Footings bearing into firm, native soils may be designed using maximum allowable bearing capacities of 1,500 psf dead load and 2,000 psf dead plus live load. Using these values, settlement is expected to be less than 3/4 inch.

3. 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.

Pole Foundations

1. Pole foundations may be utilized for the café structure. The pole foundations should have a minimum diameter of 24 inches and extend a minimum depth of 7 feet into native soils.

City of SLO – Mission Plaza October 21, 2022
Restroom and Café
305341-001 10 2210-071.SER

2. The pole foundations should not be constructed closer than two diameters (clear span) to each other without approval from this firm.

3. When the foundation acts in compression, an allowable shaft resistance value 300 psf for native soils. No end bearing capacity should be used in the calculations. For resistance to lateral loads, pole foundations may be designed using an ultimate passive equivalent fluid pressure of 250 pcf. Passive and friction components may be combined in the analysis without reduction to either value.

4. The pole foundations should be connected on at least two sides with grade beams a minimum of 18 inches deep. The foundations should be designed to act as an integral unit.

5. The soils may not stand vertically during the caisson construction. Casing, drill fluid, or other means of keeping the hole open may be necessary.

6. As the pole foundations will utilize side resistance 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 should be removed by means of a clean-out bucket or other suitable means. As stated earlier, use of end-bearing capacity is not recommended.

7. Concrete used in pole foundations should be placed at a slump between 4 and 6 inches in dry excavations.

8. The pole foundations should not deviate from a plumb line taken from the center of the foundation by more than 2 percent of the foundation length, from the top to the point of interest.

9. All pole foundations should be concreted the same day as they are drilled. If this is not practicable, the pole foundationsshould be secured in a safe manner in conformance with CalOSHA or other applicable safety standards until they are concreted. Any pole foundation excavation that has not been concreted the same day as it was drilled should have the soil and rock surfaces “freshened” by extending the rotating auger into and out of the hole several times, and the additional slough and debris removed, immediately prior to placement of the rebar and concrete.

305341-001 11 2210-071.SER

10. Special inspection of the drilling of the pole foundations as well as placement of the reinforcing and concrete should be provided.

Foundations – General

1. Allowable bearing capacities may be increased by one-third when transient loads such as wind or seismicity are included.

2. The seismic acceleration site parameters included in the table below have been provided to the design team for use in its analyses. The 2010 ASCE 7 method with 2013 updates, available on the Structural Engineers Association of California website (SEAOC 2021), was used to obtain the parameters. The project was considered to be a “nonessential” facility from the perspective of risk category as described by the CBC. The site coordinates stated in the “Introduction and Site Setting” section were used in the analysis. Based upon the subsurface conditions encountered during our investigation, the site should be classified as Site Class D (Stiff Soil). Foundations may be designed using the following 2019 CBC seismic parameters.

3. For resistance to lateral loads, shallow foundations may be designed using an ultimate passive equivalent fluid pressure of 350 pcf and a friction factor of 0.35. Passive and friction components may be combined in the analysis without reduction to either value.

Lateral capacity is based on the assumption that any backfill adjacent to foundations has been properly compacted.

305341-001 12 2210-071.SER

4. 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 just above, prior to application of compactive effort, 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 pedestrian slabs-on-grade 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 at 24 inches on center each way. All structural slabs should contain minimum rebar meeting the criteria of ACI 318 (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. Exterior pedestrian flatwork should have thickened edges a minimum of 6 inches below the bottom of the slab.

3. 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.

4. Flatwork at doorways, and at other areas where maintaining the elevation of the flatwork is desired, should be doweled to the perimeter foundations or other adjacent improvements. The dowel spacing and diameter should match that of the reinforcement.

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.

305341-001 13 2210-071.SER
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 more common 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.

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 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.

City of SLO – Mission Plaza October 21, 2022
Restroom and Café
305341-001 14 2210-071.SER

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. 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 clean sand should be placed over the compacted soil material to reduce the chance of puncturing the vapor retarder.

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 retarded 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 utility 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.

Drainage and Maintenance

1. Unpaved ground surfaces should be graded during construction, and per Section 1804.4 of the 2019 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. Finished surfaces should be sloped to freely drain toward appropriate drainage facilities.

Water should not be allowed to stand or pond on or adjacent to slopes or other improvements.

3. Where infiltration stormwater control measure areas will lie within 8 feet of foundations, 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 the bottom of the infiltration facility, whichever is deeper. It is not anticipated that this protection needs to extend greater than 8 feet.

4. The eaves of the proposed building should be provided with roof gutters. Runoff from roof gutters, downspouts, area drains, weep holes, etc., should discharge to an appropriate outlet in a nonerosive manner away from foundations and other

City of SLO – Mission Plaza October 21, 2022
Restroom and Café
305341-001 16 2210-071.SER
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.

5. Stabilization of surface soils, particularly those disturbed during construction, by vegetation or other means during and following construction, should be implemented to protect the site from erosion damage. Care should be taken to establish and maintain vegetation.

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 during grading and foundation construction

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

Restroom and Café
305341-001 17 2210-071.SER
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 by the architect/engineer and periodic special inspection of the following items should be provided by the special inspector.
• Stripping and clearing of all existing improvements, vegetation and unsuitable materials
• Overexcavation to the recommended depths
• Scarification, moisture conditioning, and compaction of the soil • Fill quality, placement, moisture conditioning and compaction • Utility trench backfill
• Foundation excavations
• Subgrade and AB/nonexpansive fill compaction and proof-rolling

4. 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.

5. Locations and frequency of compaction tests should be per the recommendation of the geotechnical engineer at the time of construction. The recommended test location and frequency may be subject to modification by the geotechnical engineer, based upon soil ad moisture conditions encountered, size and type of equipment used by the contractor, the general trend of the results of compaction tests, or other factors.

6. 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.

7. The geotechnical engineer should be notified at least 48 hours prior to beginning construction operations. If Earth Systems Pacific is not retained to provide construction observation and testing services, it shall not be responsible for the interpretation of the information by others or any consequences arising therefrom.
