graphically versus depth on Plates 6, and 7, CPT Data, CPT 1 and CPT i The results of testing performed to assess the plasticity of the dark near surface silty clays .are presented on Plate 8, Atterberg Limit Data. The results of testing performed to assess the relative percentages of fines in samples obtained at depth are presented on Plate 9, Grain Size Data. The results of testing performed to assess pavement subgrade properties are presented on Plate 10, Resistance Value Data.

PROPOSED CONSTRUCTION
We understand it is proposed to cons1mct a two story tilt-up concrete city hall building with a footprint area on the order of 22,000 square feet. We would expect the elevated floor to be a pan deck, portions of which will be suppoited on isolated foundations internal to the structure. The perimeter line load is expected to be about 10 kips per foot. The construction also will include on the order of 150 spaces for automobile parking. A bio-swale will be constructed on portions of the property near Wildcat Creek.

SITE CONDITIONS

SURFACE
The site consists of the Parcel B and a portion of Parcel A as identified on the August 31, 2016 topographic drawing by Kister, Savio & Rei, Inc. Both parcels are southwesterly of the relatively recently (2011) constructed West County Health Center and an associated parking structure; the trace of Wildcat Creek defines the project property on the southwest. A recently completed Walgreen's outlet is across Chattleton Lane to the nOlth-northwest. Ground surfaces on the property slope downward from the northwesterly property comer (+82±feet) to the crown of bank along Wildcat Creek (+74± feet+).

Research and aerial photo intelpretation indicate that the area across the present Chattleton Lane, as well as the areas of the West County Health Center and associated parking structure across Gateway Avenue were all part of an asphalt. concrete (AC) paved trailer park in the past. Review of Google Earth® imagery obtained in October 2011 would indicate that portions of the pavements within the area across Chattleton (the present location of the Walgreens) and the areas of the West' County Health Center and associated parking structure were being pulverized at that time. It also would appear that the subject site was being used as a staging area for the pulverization operations at the time of the October 2011 photography. This conclusion is supported by materials we engaged locally in our explorations. Observations made at the time of our most recent site visit indicate that drain inlets (two of them) and a "V" gutter that connects them were constlUcted in conceIt with the

trailer park pavements, significant portions of which remain. Intact pavement and AC grindings section thicknesses we measured at Oill' exploratory/sampling sites are tabulated in table I below.

SUBSURACE
As indicated in Table I above, much of the property is covered with either intact AC/aggregate base (AB) sections and/or grindings generated as described in the Surtace section above. The uppermost native soils consist of dark silty clays of moderate to high plasticity and at least stiff consistency. In the case of Borings 2 and 3, located within 400 to 500 feet of the trace of Wildcat Creek, respectively, the described silty clay deposits were found to be underlain by a three- to eight-foot­ thick interval of more so granular soils likely attributable to overbank flow of Wildcat Creek. In the case of the deeper Boring 3, predominately cohesive soils were found to extend to a depth of 42 feet; consistencies within this deeper cohesive soil interval generally range from very stiff to stiff, although unconfmed strength testing of somewhat siltier samples obtained within the depth interval between 25 and 30 feet indicate soft consistency. An approximate one-foot-thick silty sand stratum also was encountered at a depth of about 35 feet within this otherwise relatively thick silty clay stratum. Medium dense sands were engaged in the interval between depths of 42 and 50 feet.

GROUNDWATER
Stabilized free groundwater was encountered at a depth of20 feet in Boring 3. In as much as the indicated groundwater level was measured in the mid-spring of a record rainfall season, we 'would expect the measured groundwater level to be appropriate for use in design.

RECOMMENDATIONS

EARTHWORK
General
Owing to liquefaction potential, deepened foundation support/site improvement is contemplated; recommendations addressing this means of support are being developed at this time and will be presented under separate cover. Irrespective of the specifics of the support system, it will be necessary to decouple the supporting elements from the supported elements.

The design/build contractor with whom you are negotiating has indicated that one foot of crushed rock! AB or similar will be required separate the site improvement elements from the overlying foundations and structure. In addition, to mitigate soil expansion potential the placement of at least eight inches of ABI ASB will be required beneath a minimum four inch thick three-quarter inch crushed rock section immediately underlying the slab. For the above reasons, uncovering of pavements which are buried, the pulverization of exposed pavements and the mining of pavement base materials and pavements, which already have been pulverized should provide for the most cost efficient means to generate the necessary granular materials. In as much as significant portions of the site support/contain AC, AB, and grindings appar'ently remnant fi:om earlier pulverization operations, it would seem wise to expose remaining ACI AB/grindings and to stockpile and/or lay-up these pulverized AC, ABI ASB materials for use in the upper eight inches of the pad.

Clearing and Site Preparation
Site clearance should include the removal of grasses. Because of the grasses in many areas are growing through pavements, this clear'ing will have to be accomplished by close cutting or similar. Small diameter pipes (one-half inch or less) within two feet of original or final grade should be removed. Larger diameter pipes, including the storm drain piping associated drain inlets and the sanitary sewer shown on the cited 2016 Kister <h:awing should be removed completely, regardless of depth. Any fill materials identified by our representatives in the field should be over-excavated to expose firm undisturbed soils. Existing pavements should be pulverized, and base materials mined as discussed in the General section above.

File No. 2270-021.01
September 14, 2017
Compact ion
Native silty clays designated to receive fill materials or left at existing grades should be scarified to a depth of at least eight inches, moisture conditioned to a minimum three percent over-optimum state and re-compacted to a minimum degree of relative compaction of 90 percent in accordance with the ASTM D1557 procedure for fills less than five feet deep relative to finished grades, and 95 percent relative compaction at greater depths. Fill materials consisting of native silty clays should be moisture conditioned to a minimum tlu'ee percent over-optimum moisture content, placed in maximum eight inch loose lifts and compacted to a minimum degree of relative compaction of 90 percent in the case of fills at depths less than five feet relative to finished grades, and 95 percent in the case of fills at greater depths. Moisture conditioning to near optimum will be appropriate in the case of more so granular soils, pulverized pavements and mined base materials. Compaction of the later materials should achieve 95 percent relative compaction.

All excavations should be perfOlmed to the lines and grades and within the tolerances specified on the project drawings. Allover-excavation below the specified grades should be backfilled at the earthwork contractor's expense and should be compacted in accordance with the recommendations ofthis report.

Testing
All earthwork construction should be subject to thorough testing and observation by our film.

Because of the pulverization of existing AC, mining of AB, presence of existing grindings and the need to maintain the gradational quality of these materials, the involvement of our firm will be of particular impOliance.

PAVEMENTS
Pavement design has been based upon the Caltrans Design Method for Flexible Pavements, Portland Cement Association (PCA) methods .in the case of rigid pavements, the resistance (R) value data presented on Plate 10, and traffic indices (TIs) attributable to the anticipated pavement usage withln a 20 year design life. The Asphalt Institute generally recommends use of a traffic a TI of 4.5 for automobile parking lot wheel loads, a TI of 5.0 for areas subject to channelized automobile traffic; and a TI of at least 5.5 for areas subject to weekly waste removal truck traffic.

Recommended pavement sections, both flexible and rigid, for the ind.icated TIs are presented in Table II on the next page. Note that the recommendations provide for use of aggregate sub-base

(ASB) materials, which depending upon available quantities and the quantities used within the building, mayor may not be available.

PHASE I SITE ASSESSMENT
Circle S Area Project San Pablo California
BASELINE Environmental Consulting preparedthis Phase I Environmental Site Assessment for the Circle S Area Project site in San Pablo California for LSA Associates Inc The scope of work for the Phase 1 investigation included a review of historical land use information interviews a site reconnaissance and a review of regulatory agency database information The project site consists often parcels totaling approximately 18 acres in area The majority of the project site is currently used for single family residences and mobile home parks Other land uses include a roadway open space a warehouse a thrift store and a termite control business The termite control business on Parcel 10 is the only current land use likely to use store and or dispose of hazardous materials in quantities of concern The project site was developed for its current uses between 1939 and 1965 with the exception ofa residence on Parcel 5 which was present prior to 1939 and a thrift store on Parcel 9 which was developed between 1982 and 1993 Land uses associated with hazardous materials identified from historical records include a plumbing and tire recapping shop on Parcel 4 redevelopedbetween 1958 and 1965 as a mobile home park truck repair and a lumber yard on Parcel 6 and a gasoline service station at the mobile home park on Parcel 8 A gasoline underground storage tank UST was present at Parcel 6 from at least 1949 until 1992 when it was removed under regulatory oversight During removal releases from the UST piping were discovered Contaminated soil was excavated and treated and the release case was closed by San Francisco Bay Regional Water Quality Control Board RWQCB in 2001 A soil stockpile approximately 40 to 50 cubic yards in volume was present near the western boundary of the parcel during the field reconnaissance A current tenant indicated that the stockpile contained treated soil from the UST excavation at the parcel A gasoline service station was present at the Circle S mobile home park Parcel 8 from at least 1945 until the 1970s or 1980s As no information regarding former USTs at the service station was identified in regulatory agency records or the site reconnaissance for this investigation it is uncertain whether the USTs were removed or whether releases from the USTs may have occurred during operation of the service station Evidence of hazardous materials use storage or release identified during the site reconnaissance was limited to the termite control business on Parcel 10 where termiticides and wood preservative compounds were stored in a gravel floored shed The chemicals stored in the shed during the reconnaissance were relatively low toxicity and would not present a health risk ifused as directed but other chemicals that are known or likely to have been used and stored at the project site in the past are highly toxic If spills of these chemicals have occurred in the past harmful concentrations of contaminants could be present at this parcel Y 449 circle s rpt rev wpd J2 3 04 Vl
Executive Summary continued
Ten sites within one mile of the project site including one of the project site parcels and three adjoining properties appear on Federal State and local agency databases of sites associated with hazardous materials storage disposal or release After review of details regarding the locations and current status of these sites none of the reported releases are likely to have affected the project site
Review of site history information indicates that nearly all of the permanent structures at the project site were constructed prior to the 1980s and therefore may contain lead based paint and or asbestos containing materials Demolition ofthese structures may have the potential to release lead particles and asbestos fibers into the air where they could potentially pose a health risk to construction workers and the general public Adherence to applicable laws and regulations would minimize impacts to human health and the environment BASELINE recommends that additional investigation be conducted to evaluate whether USTs may be present at the former service station at Parcel 8 and or whether releases from the USTs may have occurred during operation of a service station at the parcel Additional shallow soil samples should be collected from the project site to determine whether contaminants from treated lumber stored on Parcel 6 during the 1960s through the 1990s and or pest control chemicals and wood preservatives stored on Parcel 10 may have been released at the project site Analytical results from the investigations should be compared to RWQCB Environmental Screening Levels ESLs to determine whether additional action may be required at the site BASELINE further recommends that a lead based paint and an asbestos containing material survey be completed at project site buildings prior to demolition Y 4491 circle s rpl rev wpd 12 3104 Vll

PHASE I SITE ASSESSMENT

CIRCLE S AREA PROJECT
San Pablo California

INTRODUCTION
This report presents the findings and conclusions of a Phase I environmental site assessment for the Circle S Area Project site in San Pablo California This Phase I investigation was undertaken by BASELINE Environmental Consulting for LSA Associates Inc in support of environmental review of a redevelopment project The Redevelopment Agency of the City of San Pablo is proposing to redevelop the project site with a mixed density housing development The development would also include a multi use trail adjacent to Wildcat Creek The purpose for the Phase I investigation was to determine the potential for hazardous materials to be present at the project site by examining current and past land uses and records of known releases of hazardous materials at and near the project site
The scope of work for this Phase I investigation included a review of historical land use information including aerial photographs topographic maps fire insurance maps and city directory abstracts a site reconnaissance interviews with persons familiar with the project site a review of Federal State and local regulatory agency databases and the development of recommendations for further actions All Phase I activities were performed in accordance with the Standard Practice for Environmental Site Assessments Phase I Environmental Site Assessment Process established by the American Society for Testing and Materials ASTM in Method EI527 00

SITE DESCRIPTION
The project site consists often parcels totaling approximately 18 acres in area located along San Pablo A venue south of its intersection with Church Lane Figures 1 and 2 Parcel numbers Assessor s Parcel Numbers APNs acreage owners and current uses are shown on Table 1 The project site is bordered to the north by Church Lane to the west by Wildcat Creek to the south by commercial and residential properties and to the east by San Pablo Avenue Figure 2 The project site is level and located approximately 85 feet above mean sea level msl USGS 1993 Soils in the project vicinity have been classified by the US Department of Agriculture Soil Conservation Service as fine grained silty clays to a depth of at least five feet below ground surface bgs EDR 2004a Based on topographic features shallow groundwater at the site would be expected to flow generally to the west southwest A review of groundwater monitoring well data within one mile of the project site indicates that shallow groundwater is encountered between ten and 28 feet bgs EDR 2004a

HISTORICAL LAND USES I
Historical land uses at the project site were determined by reviewing historical aerial photographs from 1939 1947 1965 1982 and 1993 historical Sanborn Fire Insurance maps from 1949 1966 and 1970 and historical topographic maps from 1932 through 1993 Historical land use resources reviewed for this investigation are included as Appendix A In 1932 the date of the first available topographic map the project vicinity was sparselydeveloped San Pablo A venue and Church Lane were both present in their current alignments Six structures were shown on or adjacent to the project site The 1939 aerial photograph shows most of the project area remained undeveloped A few small buildings were present on Parcels 1 4 and 6 residences were present on Parcels 2 and 5 and farmhouses and agricultural buildings were present on parcels 8 9 and 10 Much of the project site appeared to be pastureland The 1947 aerial photograph showed that the current warehouse building on Parcel 6 had been constructed and approximately one fourth of Parcel 8 was used for mobile homes A single family residence had been constructed on Parcel 10
The 1949 Sanborn Fire Insurance map provides the first detailed information regarding land use on the project site and adjoining properties Figure 3 It shows that the small structure on Parcell was a combined residence shop that the residence on Parcel 2 had been abandoned that the commercial buildings on Parcel 4 were used for plumbing and tire recapping shops and that the commercial buildings on Parcel 6 included a truck repair shop an office and a gasoline underground Y 4491 circle s rpt rev wpd 12 3 04 4

storage tank UST The buildings at the mobile home park on Parcel 8 referred to as a trailer camp on the map included a wash house and a restaurant Figure 3 Adjoining land uses included residences and small shops including a small sheet metal works east of Parcel 2 and two auto repair shops across San Pablo Avenue from the project site
Research performed for a cultural resources analysis of the project site identified a former gasoline service station at Parcel 8 beginning in the 1940s In phone directories from 1945 through 1959 Beck s Service Station was listed at 2980 San Pablo Avenue equivalent to 13605 San Pablo Avenue under the current address system Kelley 2004 This address would be located on Parcel 8 south of the current trailer park offices Walter Beck the owner of the service station and Waldo Beck his son are deceased and no other members of the Beck family were located during preparation of the cultural resources analysis Long time residents of the project site have suggested that the service station was present at the site until the 1970s or 1980s Kelley 2004 It is not known whether USTs may be present at this site as no information regarding the USTs was available in historical land use records or regulatory agency information discussed below under Regulatory Agency Database Review
The 1958 aerial photograph showed that the abandoned residence on Parcel 2 had been demolished six new residences had been constructed on Parcel 5 and Parcel 7 had been developed as a mobile home park The mobile home park on Parcel 8 had expanded to approximately one half of the parcel
The 1965 aerial photograph and 1966 Sanborn Map Figure 4 showed that the commercial buildings on Parcel 4 had been demolished and that parcel had been redeveloped as a mobile home park Parcel 6 had been cleared and paved and lumber and or other building materials were stacked in neat rows over the entire parcel The mobile home park on Parcel 8 had expanded to its current dimensions and the restaurant building at Parcel 8 had been converted to a mobile home sales office No significant changesin land use were noted on adjoining properties with the exception of a rest home constructed west of the project site across Wildcat Creek No additional changesin land use were noted at or adjacent to the project site on the 1970 Sanborn Map or 1982 aerial photograph The 1993 aerial photograph showed that between 1982 and 1993 the small structure on Parcell was demolished the farm house on Parcel 9 was demolished and replaced with the current retail store and the Walgreens drug store building was constructed adjacent to the project site

CURRENT LAND USES SITE RECONNAISSANCE
A visual reconnaissance of the project site and adjoining properties was conducted by a BASELINE geologist on 21 July 2004 Observations made during the site reconnaissance are detailed below Photographs of the project site taken during the site reconnaissance are included on Figures 5 through 10

Parcels 1 2 and 3 Chattleton Lane and Open Space
Parcels 1 2 and 3 consist of Chattleton Lane and a vacant area east of Wildcat Creek Figure 2 Wildcat Creek was dry at the time of the reconnaissance Photo 5A The creek channel was approximately 12 feet deep and 25 to 30 feet wide Chattleton Lane is a narrow roadway that provides access to Parcels 5 and 7 Photo 5B The roadway is used for automobile parking and a dumpster No evidence of current or historical use storage or disposal of hazardous materials was noted in this area
Parcels 4 5 7 and 8 Residential Parcels
Parcels 4 5 7 and 8 were developed as residences Parcel 5 contained seven single family residences and Parcels 4 7 and 8 contained approximately 225 mobile homes Figure 2 and Photos 6A and 6B No evidence ofa former service station underground storage tanks or other current or historical use storage or disposal of hazardous materials was noted on these parcels Parcel 6 Former Davis Lumber Yard
This parcel contained a single story structure currently used as a warehouse by Romastone Precast Studio Photo 7 A The remaining portion of the parcel was a vacant area pavedwith asphalt which was in poor condition Photo 7B Sanborn fire insurance maps discussed above under Historical Land Use Information above identify a UST at this parcel from at least 1949 According to regulatory agency records discussed below under Regulatory Agency Information this UST was removed in 1992
One ofthe current tenants pointed out the former UST location Photo 8A and approximately 40 or 50 cubic yards of soil stockpiled in the southwest comer of the parcel Figure 2 and Photo 8B The tenant indicated that the soil was treated soil from the UST excavation and was originally covered with a plastic tarp No tarp or other covering was apparent during the site reconnaissance Regulatory information reviewed for this investigation indicated that contaminated soil affected by leaks from the UST piping was removed during the tank excavation and treated see discussion under Regulatory Agency Information below The City Redevelopment Agency suggestedthat the soil may have been placed on the site as part of a City project Worthy 2004 however the Public Works Department was not aware of any City activities that could have generatedthe stockpile Ho 2004
No evidence of past releases from historic truck repair operations at the warehouse was apparent during the site reconnaissance From the 1960s through the 1990s the site was used to store lumber and other building materials If treated lumber was stored it is possible that wood preservative compounds could have leached from the lumber and affected project site soils The most common wood preservative compound is chromated copper arsenate CCA which contains chromium copper and arsenic rfCCA had leached from the lumber hazardous concentrations of these metals could be present in site soils Pentachlorophenol PCP is a commonly used oil based wood preservative which is a carcinogenic and binds tightly to soils therefore shallow soils may contain leached PCP from lumber

Parcel 9 Salvation Army Thrift Store
Parcel 9 contained a single story retail structure and parking for store patrons and donation collection vehicles Photo 9A No evidence of current or former use storage or disposal of hazardous materials was apparent at this parcel
Parcel 10 Fisk Termite Control
Parcel 10 contained a single story former residence that is now used for the office of a termite control business Photo 9B The manager indicated that the termite business had been present at the site for over 30 years Behind the office was a gravel paved area with parking for a boat and several vehicles a dumpstercontaining building materials and three sheds Photo lOA Two of the sheds were used to store building materials and one sheet metal gravel floored shed was used for chemical storage Photo lOB
Two termiticides were stored in boxes in the shed Tim bor an inorganic borate compound and Premise 75 classified as a chloronicotinyl compound Material Safety Data Sheets MSDSs for these products are included as Appendix B The termiticides currently stored in the shed are low toxicity compounds that would be unlikely to affect human health when used as directed More toxic compounds were used at the site in the past Prior to the late 1980s the most common termiticide in the US was chlordane an organochlorine compound which was sold in the US from 1948 until 1988 when it was withdrawn from the market After 1988 Dursban the trade name for an organophosphatecompound was commonly used as a chlordane replacement The manager of the business confirmed that chlordane and Dursban had been stored and mixed at the site in the past These compounds are of particular concern because ifreleased to soil hazardous residues could be present that may persist for decades
Several containers of wood preservative Copper Green were also stored in the shed Although Copper Green does not contain arsenic many wood preservatives commonly used in the past are based on chromated copper arsenate CCA which contains chromium copper and arsenic Although no evidence of any releases was noted during the site reconnaissance releases of wood preservative if they had occurred could also result in toxic residues in soils at this parcel Adjoining Properties
Adjoining land uses are shown on Figure 2 Adjacent properties included townhouses condominiums a senior housing center a Walgreens drugstore small commercial businesses a private high school a mortuary and medical professional offices None of the adjoining land uses was likely to use store or dispose of hazardous materials in quantities of concern and no evidence of releases at these properties that could affect the project site were identified during the reconnaIssance

LEAD AND ASBESTOS IN BUILDING MA TERIALS
The proposed project alternatives will likely require the demolition of several structures on the project site Permanent structures at the project site include seven single family residences on Parcel 5 a warehouse on Parcel 6 a retail store on Parcel 9 and a pest control business in a former residence on Parcel 10 With the exception of the retail store based on the age of the buildings it is likely that lead based paint and asbestos containing materials will be present II
Lead oxide and lead chromate were commonly used in paints until 1978 when regulations limited the allowable lead content in paint Therefore painted surfaces at buildings constructed prior to 1978 have the potential to contain lead based paint Federal and State regulations govern the demolition of structures where lead or material containing lead are present During demolition lead based paint that is securely adhering may be disposed of as a demolition debris which is a non hazardous waste Loose and peeling paint must be disposed of as a California and or federal hazardous waste if the concentration oflead exceeds applicable waste thresholds State and Federal construction worker health and safety regulations require air monitoring and other protective measures during demolition activities where lead based paint is present Asbestos was commonly used in construction materials until the 1980s when its use was phased out Therefore building materials manufactured prior to the 1980s have the potential to contain asbestos fibers which could be released during demolition activities Federal State and local requirements govern the removal of asbestos or suspected asbestos containing materials including the demolition of structures where asbestos is present All friable crushable by hand asbestos containing materials ACM or non friable ACM subject to damage must be abated prior to demolition in accordance with Bay Area Air Quality Management District BAAQMD requirements Friable ACM must be disposed of as an asbestos waste at an approved facility Non friable ACM may be disposed of as non hazardous waste at landfills that will accept such wastes Workers conducting asbestos abatement must be trained in accordance with State and Federal OSHA regulations Y4491 c rcle s rpt rev wpd 12 3 04 22

CONCLUSIONS
The project site consists often parcels totaling approximately 18 acres in area The majority ofthe project site is currently used for single family residences and mobile home parks Other land uses include a roadway open space a warehouse a thrift store and a termite control business The termite control business on Parcel 10 is the only current land use likely to use store and or dispose of hazardous materials in quantities of concern The project site was developedfor its current uses between 1939 and 1965 with the exception of a residence on ParcelS which was present prior to 1939 and a thrift store on Parcel 9 which was developed between 1982 and 1993 Land uses associated with hazardous materials identified from historical records include a plumbing and tire recapping shop on Parcel 4 redevelopedbetween 1958 and 1965 as a mobile home park and a truck repair and a lumber yard on Parcel 6
A gasoline underground storage tank UST was present at Parcel 6 from at least 1949 until 1992 when it was removed under regulatory oversight During removal releases from the UST piping were discovered Contaminated soil was excavated and treated and the release case was closed by RWQCB in 2001 A soil stockpile approximately 40 to 50 cubic yards in volume was present near the western boundary of the parcel during the field reconnaissance A current tenant indicated that the stockpile contained treated soil from the UST excavation at the parcel
A gasoline service station was present at the Circle S mobile home park Parcel 8 from at least 1945 until the 1970s or 1980s As no information regarding former USTs at the service station was identified in regulatory agency records or the site reconnaissance for this investigation it is uncertain whether the USTs were removed or whether releases from the USTs may have occurred during operation of the service station Evidence of hazardous materials use storage or release identified during the site reconnaissance was limited to the termite control business on Parcel 10 where termiticides and wood preservative compounds were stored in a gravel floored shed Although the chemicals stored in the shed during the reconnaissance were of relatively low toxicity and would not present a health risk ifused as directed other chemicals that are known or likely to have been used and stored at the project site in the past are highly toxic If spills of these chemicals have occurred in the past harmful concentrations of contaminants could be present at this parcel
Ten sites within one mile ofthe project site including one ofthe project site parcelsand three adjoining properties appear on Federal State and local agency databases of sites associated with hazardous materials storage disposal or release After review of details regarding the locations and current status of these sites none of the reported releases are likely to have affected the project site
r Y 4491 circle s rpt rev wpd J 2 3 04 23
Review of site history information indicates that nearly all of the permanent structures at the project site were constructed prior to the 1980s and therefore may contain lead based paint and or asbestos containing materials Demolition of these structures may have the potential to release lead particles and asbestos fibers into the air where they could potentially pose a health risk to construction workers and the general public Adherence to applicable laws and regulations would minimize potential impacts to human health and the environment

RECOMMENDA TIONS
A geophysical survey should be performed in the vicinity of the former service station at Parcel 8 to determine whether abandoned fuel or waste oil USTs may be present IfUSTs are identified they should be removed under regulatory oversight in accordance with applicable regulations which would include the collection of samplesfrom the excavation to determine whether releases from the USTs may have occurred
A limited soil and groundwater investigation should be performed at the project site to determine whether hazardous materials releases may have occurred at Parcels 6 8 and 10 as a result of historical land uses
Shallow soil samples from 0 to 3 feet below ground surface should be collected from areas of the parcel where treated lumber was stored Samples should be analyzed for total chromium copper and arsenic EP A Method 60 I 0 and for pentachlorophenol EP A Method 8040 or 8270
Shallow soil samples from 0 to 3 feet below ground surface and soil samplesfrom near the groundwater interface estimated to be between 10 and 28 feet bgs should be collected from near former UST and dispenser locations at the former service station at Parcel 8 Grab groundwater samplesshould be collected from the soil borings The soil and groundwater samples should be analyzed for total petroleum hydrocarbons as gasoline diesel and motor oil EP A Method 8015 and benzene toluene ethylbenzene and xylenes EP A Method 8260 Shallow soil samples from 0 to 3 feet below ground surface should be collected from areas within and around storage sheds at Parcell O Samplesshould be analyzed for organochlorine pesticides EP A Method 8081 organophosphatepesticides EP A Method 8141 and total chromium copper and arsenic EP A Method 60 I 0
Analytical results should be compared to RWQCB Environmental Screening Levels ESLs for residential land uses ESLs are conservative human health and ecological risk based concentrations used for screening purposes If any contaminant concentrations exceed the ESLs then additional action may be required such as preparation of a human health or ecological risk assessment remediation of the contaminated soils e g excavation and off site disposaI and or implementation of institutional controls and engineeringcontrols IC EC in project design IC EC may include the use of hardscape buildings and pavements Y 4491 circle s rpl rev wpd 12 3 04 24
importation of clean soil in landscaped areas to eliminate exposure pathways or deed restrictions
Prior to demolition of buildings known or suspectedof construction prior to 1980 a lead based paint and asbestos containing materials survey should be conducted by a certified professional Identified loose and peeling lead based paint and asbestos containing materials should be abated in accordance with applicable regulations Federal and state construction worker safetyregulations should be followed during demolition activities where lead and or asbestos are known or suspectedto be present

Dear Members of the Selection Committee:

LPA is honored to submit our proposal for the City of San Pablo’s New Police Facility Project. Over the last 20 years, our firm has developed an extensive track record of programming and designing high-performance public safety environments. In 2021, LPA was named California’s Firm of the Year by the AIA California Council. This award is a testament to the client centered, sustainable approach we bring to our work; we are sure that we can help you achieve your vision.

Our firm operates a bit differently. We have integrated all the design and engineering disciplines under one firm. This integration allows us to break down the barriers between disciplines. We bring together in-house experts in architecture, engineering, interior design, landscape architecture, and master planning to collaborate with clients from start to finish. For your project we will be combining the resources of our Sacramento and Irvine studios to provide you with the experience and local resources necessary to complete your project successfully. Our ability to draw upon our vast resources allows us to meet your schedule.

We have designed numerous police stations, headquarters and essential service facilities including recent projects for cities of Salinas, Visalia, Merced, Campbell, and the County of San Bernardino. From our firm, we have assembled a team of public safety experts with current project experience to better serve the City of San Pablo as you look to create bridging documents for a Design-Build Police Facility.

LPA has a solid understanding of the public safety service needs and will lead the design team’s efforts through the planning, design, and initial engineering of the project while giving consideration to the community impact as well as the impact of local, regional, and state regulations.

The benefits of partnering with us include:
• Civic design expertise and leadership. We are strategic thinkers and problem-solvers with extensive experience in the unique opportunities and challenges of planning and designing for cities. Our firm has successfully completed more than 270 civic projects, including police, fire, and essential service facilities. • A better process, with better results. As an integrated design firm and consultant team, we offer a multidisciplinary team of architects, planners, police facility programmers and cost estimators, engineers, landscape architects, interior designers and researchers all working together, many of which are in-house from project start to finish. It’s a seamlessly collaborative process that generates better ideas, value, and outcomes for your project. • A closer client relationship. When you choose the LPA team, you get a dedicated and responsive design partner you can count on. We work closely with all stakeholders throughout every stage of your project—listening closely to your needs, sharing ideas, keeping the project on budget and on schedule and shepherding you through any challenges that arise.

Stapleton v. Pacific Construction Group
Explanation - LPA was sued in a job site bodily
injury accident case by a subcontractor’s
employee who sustained severe injuries when
he fell from a fixed ladder while installing a
new HVAC system on the roof of a 40-year-old
building. LPA did not design the building or the
ladder. The Owner hired LPA to design a new
HVAC system and associated roofing upgrades.

LPA’s contract specifically excluded job site safety
during construction, which were the contractor’s
responsibility. The City Building Inspector had
told the Owner and the Contractor that the
Ladder was unsafe and not code compliant, but
they failed to advise the Plaintiff or LPA. Plaintiff
and his wife sued multiple parties for personal
injury damages and loss of consortium in excess
of $10 Million. LPA denied any responsibility
and cross-complained about indemnity and
defense against the Owner, the contractor and
the subcontractors. LPA was granted a motion for
summary judgment requiring the subcontractors
to defend LPA. The case was settled in
September 2019 for over $6 million paid by the
Owner, the contractor and the subcontractors.

LPA paid nothing in the settlement and was
reimbursed by the subcontractors for attorney’s
fees and costs it had incurred in defending the
claim.

Date of Notice: March 15, 2016
Status: Resolved September 2019 through
mediation.

Court: Superior Court of Los Angeles
Case No.: BC613913
Palomar Community College District
Explanation - The General Contractor (Gilbane)

square foot four-story building and accompanying
improvements. Gilbane cross-complained against
the District for delay claims and the District
cross-complained against LPA for express
indemnity and declaratory relief arising from the
trade subcontractor claims for schedule and cost

City of San Pablo | Bridging Architect for New Police Facility impacts. The District has not alleged claims for
negligence or for any wrongdoing against LPA in

the contract, and LPA entered into a joint defense
agreement with the District.

negligent supervision against the School. The
slide structure was audited and certified by
a third party playground safety analyst after
construction was completed, as a condition for
certificate of occupancy, which was subsequently
issued by the City. The School cross complained

The new Salinas Police Services Headquarters was needed as a replacement of the City’s 65-year-old existing Police Headquarters. The 69,230-square-foot Police Headquarters will be the first piece implemented in the Alisal Vibrancy Plan—a plan that seeks to create a robust framework for sustained economic opportunities that lead to a vibrant cultural district for the community.

The design of the Police Headquarters was a two-pronged approach. The building incorporates all the functional
requirements needed to operate a modern public safety
facility. The aesthetics and site planning of the project were driven by extensive community outreach. After
conducting workshops and interviews with community and
stakeholders, the design of the project is driven by and reflective of the values of the people of Salinas.

The project includes more than 250 parking stalls for
visitors, officers and staff.

22 C / DESIGN SERVICES APPROACH
City of San Pablo | Bridging Architect for New Police Facility Design Services Approach

1. Describe the approach and presentation
materials used to illustrate various concept
design alternatives and assist the City
with review. Discuss the optimum level of
collaboration between project team members.

LPA needs an engaged client in the design
process. Vaulting from the conceptual layout
already completed, LPA will elevate and explore
more possibilities for your consideration. The
presentation materials will be in the form of three-
dimensional studies of volumes, masses and forms
that respond to the contextual aesthetic. This
allows the user to participate in the organization
and design of their police facility. The Project
Team will be engaged in a program-driven design;
designing from the inside out, allowing the
function of the project to drive the form.

Within the site constraints, the exterior program
will be addressed as well. The exterior program
will “push on the outside’ of the building,
concurrent with the interior development. The
two forces—inside out and outside in—meet to
create the envelope of the building, and that is
where design occurs. Again, all this is shown in a
3D form that speaks to the program within.

In a very efficient process, we will achieve
optimum level of collaboration between project
team members. This comes when the client
knows the design, and the architect knows the
desired program. Then a ‘design partnership’ is
formed and great results are within their grasp.

2. Describe your firm’s design approach and
work product for illustrating programmatic
layout and compliance with preliminary program
and design criteria including presentation of
recommended deviations and alternatives.

LPA practices an iterative, client inclusive
approach to design. Within the confines of the
budget and site, we will respond to the program
by providing blocking and stacking options.

Keeping an eye on the pre-existing work product,
LPA will explore solutions that incorporate
different adjacencies, different work strategies,
hybrid work environments, etc. We know that a
new station will be a recruiting tool. We also know
that the younger workforce works differently.

Most young officers would rather write a report in
a Starbucks than a cubicle. LPA will challenge you
to arrive at solutions that blend tried and true best
practices with strategies of modern community
policing, and what you see in your future.

When we arrive at a refined solution, we update
the program, and cost estimate, with the new
square footage allocations and the new budget.

Plans and 3D layouts show furnishings, walls,
rooms that help the police visualize the facility in
its embryonic stages. Again, the iterative process
will weave in the project’s goals of sustainability,
design compatibility and compliance with the
Specific Plan as the Project Team moves closer
and closer to the best solution.

3. Describe how your firm will help prioritize
the needs and desires of the Stakeholders of
the Project with a limited budget and site, while
meeting operational requirements, ensuring
maintainability/durability, minimizing lifecycle
costs, and addressing LEED™ requirements.

Your propmt is such a great synopsis of the
design process! Our approach is a cyclical process
that touches upon all the above toward an ever-
increasing focused solution.

Our experience tells us that as we test the
program in three dimensions, the program
inevitably grows beyond the allowable budget
and site. We will again “hold the mirror” up to
you, the client, the user, and ask you to prioritize
what is most important to YOU. It’s your building;
we are only running alongside to assist in the
process and ask you the tough questions.

If required, we will assign prices to each program
that add up to (a fictional total of) $200. Then
we give the team a $100 to go buy what they
absolutely need. The team might choose to invest
in a more durable HVAC system to minimize long-
term lifecycle costs, or photovoltaic panels to
meet a LEED requirement. Quickly, the priorities
are established.

Most entities don’t have enough money to
build something cheap. LPA will speak for the
durability of the building, the needed storage, the
roughed in conduit for future electrical vehicle
charging stations. These demands for the future
will compete with the desire programs of today.

As your question so succinctly noted, this is the
design process.

23 C / DESIGN SERVICES APPROACH
City of San Pablo | Bridging Architect for New Police Facility

4. Describe approach to outreach with
reviewing agencies and utility providers, and to
coordination with consultant team.

Our approach to outreach with the agencies is to
invite them to the kick-off meeting. The Project
Team needs to know now – especially with the
schedule – if there are any code issues that need
to be resolved. We will reach out early and often
to the agencies having jurisdiction. They are
part of the design solution as well, and periodic
reviews will flush out obstacles early.

We will employ a Dry Utility Specialist, who
is knowledgeable about the inner workings
of the companies, to identify constraints and
opportunities early on. Early detection of utility
availability (or scarcity) helps us plan the best
strategies.

The coordination with consultant team is easiest
since most of them are in-house. We have worked
together in-house for years. We have the same
values. We "wear the same jersey”. As a single
integrated company, it is in our best interest to do
well as a team.

5. Describe your experience, approach and
work product for providing thorough Bridging
Documents serving as Basis of Design for DBE
Delivery.

Your RFP strikes a good balance between
describing the essential elements of the
project, while keeping as many elements as
possible “open for creativity” on the part of
the design-build entity. LPA has been on both
sides of the design build delivery methodology.

Completeness is key in the Bridging Documents.

We want to minimize the RFI’s for extra
clarification, but we absolutely must eliminate
the issues that push the schedule. That hurts the
client’s schedule and can be defeating to DBE
team working on a minimal stipend.

LPA works with the clients to clearly describe
what is required, and then allow for freedom of
movement with the contractors for that which is
not required.

Our deliverable mimics the format of our QA/
QC program that we engage on all our projects
at each milestone. Our checklists and inter-
disciplinary review will simply continue, albeit
with a set of drawings from an outside entity.

6. Describe approach for providing as-needed
review and support through DBE design and
delivery.

LPA will provide periodic review of the DBE
documents and ultimately the constructed
product. We will be looking for anything that
diminishes the design intent requested by the
client, and therefore, woven into the Bridging
Documents. We will look for any proposals that
might cheapen the end product and provide
the client with feedback to make a decision on a
possible cost saving option.

As your RFP has noted, this review will be by those
who were engaged in the Bridging Documents.

We drew them. We know them. We enforce them.
