Analysis:

Background
The Huntington Beach Housing Authority ( the " Housing Authority") was established in 2011 per Health & Safety Code Sections 34200 et. seq. for the purpose of addressing a shortage of safe and sanitary dwelling accommodations in the City available to persons of low income. In 2019 and 2020, the Housing Authority acquired two adjacent parcels for a total of 1.6 acres to facilitate an affordable housing project. Since acquisition, the Property has been improved with a temporary homeless shelter ( the " Navigation Center").

On March 22, 2022 a Request for Qualifications (" RFQ") ( attached as Exhibit B to the Agreement) was released soliciting qualification statements to identify qualified development partners to develop, finance, and manage a new mixed- use development consisting of a homeless shelter, a sobering center, support services ( physical and behavioral healthcare, housing navigation and employment), and transitional and low- income housing at various income levels.

The Property is located within the Neighborhood Boulevard segment of the Beach and Edinger Corridors Specific Plan (" BECSP"). This segment along Beach Boulevard ( Hwy 39) is characterized by a significant amount of ageing commercial strip development, including auto-oriented uses, such as car dealerships. Development types are dominated by one- story, single- loaded commercial buildings surrounded by surface parking lots with little landscaping or pedestrian amenities. The planning approach to this area is to facilitate long-term transition from strip retail to uses more focus on nearby populations, featuring development types that retain visibility to motorists on Beach Boulevard, while providing a more visually attractive and comfortable pedestrian environment.

Neighborhood- serving and hospital- serving retail and services, corner/ crossroads located retail, and office and office- medical are encouraged to take advantage of the proximity to the Huntington Beach Hospital and its related cluster of medical services. In-fill residential uses are also permitted throughout this segment.

Since acquiring the Site in 2020, the Housing Authority has worked with the City and County of Orange to facilitate the Navigation Center and implemented the Be Well Mobile Response program.

These accomplishments are a testament to the City Council's aspirations to address homelessness in a unique and meaningful way. The Housing Authority desires a development partner to facilitate in creating a distinct facility to support individuals from street to home. The goal of this facility is to provide space that allows the engagement of unhoused individuals and create a path from homelessness to housing; while addressing the underlying barriers that have prevented housing in the past. The desired continuum of services to be provided on site include a combination of shelter operations, a sobering center, behavioral and physical healthcare, housing navigation, and employment services.

Assessment of Qualifications
Respondents to the RFQ were asked to submit information in the following categories:

Organizational Structure
Firm' s Experience

File #: 22- 481 MEETING DATE: 6/ 7/ 2022
Relevant Experience
Financial Capacity
Respondents were required to identify their development team and provide biographies for key development staff. In addition, they were required to provide a narrative about their development approach for this particular project.

The evaluation process was designed to select a respondent, not based on the least cost, rather the respondent with the best combination of attributes ( experience, financial capacity/ ability to secure funding, and successful partnerships with service providers). The Developer submitted a qualification statement ( attached as Exhibit C) that demonstrated strong partnerships, experience and financial capacity. The Developer has partnered with Mercy House and Be Well which already have successful partnerships with the City. Equally important, the Developer effectively communicated their desire to be a partner that is equally committed to assisting the City in making significant impacts toward the well- being of our most vulnerable community members.

Exclusive Negotiating Agreement
Staff is seeking Housing Authority authorization and direction for the Executive Director to execute the Agreement with the Developer for 360 days during which the Developer may perform studies and investigations and other due diligence activities within the Property and other feasibility and financial analysis to determine the feasibility of Developer' s acquisition of the Property and the City and Developer shall exclusively negotiate with each other in an attempt to agree on the terms of an affordable housing agreement, including a fee- simple acquisition, ground lease, or other disposition.

Approval of the Agreement does not obligate the Housing Authority to enter into an Affordable Housing Agreement or any other agreement with the Developer.

During the negotiating period the Developer will conduct due diligence to fully understand the condition of the Property and any constraints to development. Collaborative discussions between the City and Developer will occur related to design and cost of a potential development project, including long- term operating costs. The Developer will also explore funding sources and financing options.

Successful negotiations will conclude in agreed upon business terms to be incorporated into an Affordable Housing Agreement. Such agreement will be brought to the Housing Authority Board for consideration along with project details including concept design, operation plan, estimated total project cost for construction, projected costs for operation, sources of funds (include Housing Authority and City contributions), Developer' s responsibilities, etc.

Environmental Status:

Pursuant to CEQA Guidelines Section 15378( b)( 5), administrative activities of governments that will not result in direct or indirect physical changes in the environment do not constitute a project. If negotiations are successful an Affordable Housing Agreement will be brought forward for the Housing Authority's considerationandan environmentalassessmentwill beconductedat that time.

1 Project Vision
The Site is located within the Neighborhood Boulevard segment of the Beach and Edinger Corridors Specific Plan (" BECSP"). This segment alongBeachBoulevard (Hwy39) ischaracterizedby a significantamount of agingcommercialstrip development, includingauto-oriented uses, such as car dealerships. Development types are dominated by one-story, single-loaded commercial buildings surrounded by surface parkinglotswith little landscapingor pedestrianamenities.Theplanningapproachto this areaisto facilitatelong-term transition from strip retail to uses more focused on nearby populations, featuring development types that retain visibility to motorists on Beach Boulevard, while providinga morevisuallyattractiveand comfortablepedestrianenvironment. Neighborhood-servingand hospital-servingretail and services, corner/crossroadslocatedretail, and officeand office-medicalare encouragedto takeadvantageof the proximityto the Huntington BeachHospitaland its relatedclusterof medicalservices.

1 Additional Site Information
TheSiteis locatedat 17642BeachBoulevardand iscomprisedof two parcels, both controlled by HBHA, totaling 1.6 acresof land. Beach Boulevard is a State highway( Hwy 39) and is a High Quality Transit Corridor with the closest bus stop located within 800 feet of the Site.The Site is located within 2,000 feet of Huntington Beach Hospital and within 1,000 feet of a Federally Qualified Health Center( FQHC). It is also located just over a half a mile from afull service grocery store. The Site is bordered by a residential neighborhood ( to the east) and commercial uses to the north, south and west.

The Site is zoned Mixed- Use- Affordable Housing Overlay( SP14- Beach and Edinger Corridors Specific Plan). SP14 is a form- based code with prescriptive development standards and allows for a mix of commercial and residential uses.The Affordable Housing Overlay allows for by-right development( i. e. no discretionary public hearing) for projects that include at least 20% of the units affordable at no more than 60% Area Median Income(" AMI").

HBHA desires 100% of the units to be affordable at various income levels with all units at 60% AMI or less. It is HBHA' s desire that the housing units qualify as supportive housing, as defined in Section 65650 of the Government Code.

As part of due diligence for acquisition, various contaminants were found on site. A full site assessment for each parcel is included as Appendices A and B. The Orange County Health CareAgency served as the oversight agency for the Navigation Center project. Their site summary and recommendations are included as Appendix C.

For informational purposes only, a Site Density Test Fitwas conducted and is included as Appendix D.

AESCOhas been retained to prepare a soils report. This report is not available at the time of publication of this RFQ. A letter containing preliminary foundation recommendations is included as Appendix E.

rM Scope of Work
HBHA, City, and Developer Roles
HBHA seeks to engage a vertical developer that would be responsible for entitlements and approvals, environmental assessments and testing, infrastructure, and community engagement related to the project. HBHA is open to that partner bringing on other developers for discrete components such as affordable housing, medical office, etc. HBHA encourages partnerships with service providers. The developer whether a singleentity or a team of individualdevelopersand serviceproviders)would alsobe responsiblefor projectdesign, securing financing, overseeing construction, leasing, and ongoing property and asset management related to the project.

HBHNs role will be the pro- rata contribution of the land for housing and securing additional, limited funding for the affordable housing. Any form of disposition of HBHA-owned land for non-residential use will be at fair- market value. HBHA is open to exploring multiple disposition and/ or partnership structures that suit the best development outcome, including but not limited to fee-simple, installment sale,joint venture or long-term ground lease.

The Citys role will be its pro-rata share of the capital and infrastructure costs associated with the shelter and will work to identify other public sources of funding for ongoing operations.

Respondents will be evaluated based on their experience leading complex mixed- use development( ideally in the space of affordable housing, homelessshelters, soberingcenters, and supportiveservices), securingentitlementsandfinancing, abilityto providea guarantee of completion, achievingdesignexcellencewhile promoting the objectivesof SP14, and demonstrated partnershipswith serviceproviders and community organizations.

1. 0 INTRODUCTION
On behalf of the City of Huntington Beach, EEC Environmental ( EEC) has prepared this Site Assessment Report for the Cameron Ln. Property located at 17631 Cameron Lane, Huntington Beach, California subject property; Figure 1, Site Location Map). The purpose of the site assessment was to address findings of EEC' s Phase I Environmental Site Assessment ( ESA) dated March 18, 2020, which identified potential use of pesticides/ herbicides and lead- based paint in connection with former agricultural use and residential use as environmental concerns and recommended soil sampling. The Phase I ESAand the site assessment activities were completed in connection with proposed redevelopment of the subject property.

This report documents the methods, procedures, and results of the site assessment activities at the subject property. All work was completed in general accordance with EEC's April 2, 2020 proposal to the City of Huntington Beach ( EEC, 2020) and subsequent correspondence between the City of Huntington Beach and EEC. All work was performed under the supervision of a California licensed Professional Geologist ( PG) and the Orange County Health Care Agency ( OCHCA).

1. 1 Scope of Work
The completed site assessment activities included the following tasks:

Preparing a site- specific health and safety plan ( HASP) appropriate for the scope of work.

Contacting Underground Service Alert ( USA) 72 hours prior to initiation of fieldwork.

Advancing 35 borings for the collection of soil and groundwater samples from depths ranging from approximately 0.5 feet below ground surface ( bgs) to 24 feet bgs.

The collection and analysis of 86 soil samples for organochlorine pesticides ( OCPs), herbicides, lead, Title 22 Metals, and hexavalent chromium and 3 groundwater samples for hexavalent chromium.

Excavation of soil containing elevated concentrations of lead and OCPs at two locations.

2. 0 BACKGROUND

2. 1 Site Description
The approximately 0.79-acre subject property consists of a residential lot identified as Assessor Parcel Number ( APN) 167- 042- 08, 17631 Cameron Lane in Huntington Beach, Orange County, California. The east side of the subject property is currently developed with an unoccupied single- family residence that was developed in 1947. A Phase I ESAwas completed for the subject property on March 18, 2020 ( EEC, 2020). The Phase I ESA indicated that based on a review of historical aerial photographs, the subject property appeared to be used for agricultural purposes (row crops) from the 1930s to the 1950s and giventhis usage, it is possiblethat pesticidesand/or herbicideswere onceusedonsite. Additionally, due to the date of construction of the residence, lead- based paint may have been used on the subject property residence. Basedon this information, the PhaseI ESArecommended soil sampling to assessfor potential residualpesticidesand herbicidesfrom former agriculturaluseandto assessfor potential lead in the location of the current building exterior.

Site Assessment Report June 25, 2020

2. 2 Physiography
The most recent topographic map coverage of the subject property is provided by the U.S. Geological Survey (USGS) 7.5-minute, Newport Beach, California quadrangle map, dated 2012 (Figure 1). According to the USGStopographic map, the subject property is located at an elevation of approximately 25 to 30 feet above mean sea level ( msl). The topography in the general subject property area slopes gently to the north- northeast.

2. 3 Geology and Hydrogeology
Onsite activities described in this report indicated that soil at the subject property consists primarily of silt at 1 foot bgs. At five feet bgs, soil consists primarily of clayey sand and sandy clay. At 8 feet bgs soil consists of silt, clayey silt, silty sand, sand, sandy clay, and clayey sand. At 20 feet bgs, soil consists of silt, clayey sand, and clayey silt. At 24 feet bgs, the maximum depth explored, soil consists of sand and silty sand.

According to a Quarterly Status Report, Second Quarter 2019 for a site located approximately 500 feet northwest of the subject property, the groundwater flow direction is southwest ( Atlas Environmental Engineering, Inc., 2019). During onsite activities, groundwater was encountered at 23 and 24 feet bgs.

3. 0 SITE INVESTIGATION ACTIVITIES
Between April 6 and May 11, 2020, a total of 35 soil borings were advanced to depths ranging from approximately 0.5 to 8 feet bgs for the collection of soil samples at the subject property. In addition, three groundwater samples were collected and two soil excavations were completed.

3. 1 Pre- Field Activities
Prior to beginning soil sampling activities, EECcompleted the following tasks necessary to initiate field activity.

3. 1. 1 Health and Safety Plan
To protect workers, EECprepared a HASP as appropriate for the scope of work. The HASP informed all site workers of potential risks during field sampling activities and provided engineering controls to avoid physical and chemical hazards. The HASP addressed potential physical and chemical hazards associated with field operations. The HASP outlined the steps to prevent exposures from all site activities. The HASP also described the safe use of equipment, evaluation of hazards, safe investigation procedures, personal protective equipment, emergency procedures and training required to conduct the site assessment under typical Hazardous Waste Operations and Emergency Response protocol.

3. 1. 2 Utility Clearance
EECcontacted USA and provided the specific property boundaries so that the proposed work area was provided to utility owners responding to the USAticket. USAis a regional notification center that notifies owners and operators of subsurface utilities ( water, gas, electric, sewer, oil lines, etc.) and informs them S3506. 02T, Huntington Beach, CA 2 94
Site Assessment Report June 25, 2020
of a contractor' s intent to perform subsurface work. EEC notified USA of the intent to perform subsurface work a minimum of 72 hours prior to the beginning of the on-site activities.

3. 2 Hand- Auger Soil Boring Advancement and Soil Sampling Between April 6 and April 28, 2020, EECadvanced a total of 27 soil borings at the subject property ( B1 through B18, B4-A, B6-A, and B26- B32; Figure 2, Boring Location Map) to total depths of 3 feet bgs. The borings were advanced using a hand auger. Once each sampling depth was reached, the hand auger was removed from the borehole and an undisturbed soil sample was collected using a slide hammer sampler including a stainless steel sampling sleeve. Following sample retrieval, both ends of the sleeve were covered with a Teflon sheet and sealed with a plastic end cap. Soil samples were then labeled with an identification number, sealed in a plastic bag, and placed into a chilled cooler.

An unused portion of soil from each sampling interval was used for field screening using a photoionization detector ( PID) for evaluation of organic vapor content and for logging lithology. Field screening was conducted by placing a portion of the unpreserved soil in a sealable plastic bag for approximately 10 minutes. The organic vapor concentration in the headspace of the plastic bag was then measured using a PID. Soil descriptions and PID measurements were recorded and documented on field notes. All field activities were performed under the direct oversight of a California PG.

All soil samples were collected and transferred under proper chain- of- custody protocols to Eurofins Calscience ( Calscience) of Garden Grove, a California state- certified laboratory. Selected soil samples were analyzed for organochlorine pesticides ( OCPs) by United States Environmental Protection Agency USEPA) Method 8081A, herbicides by USEPA Method 8151A, California Title 22 metals by USEPA Method 6010B, mercury by USEPA Method 7471A, and hexavalent chromium by USEPAMethod 7199.

The specific soil sampling method for each sample location is provided in Table 3- 1, Soil Sampling Matrix, on Page 6 of this report. Because multiple phases of soil sampling and analysis were completed, Section 3.2.1 below provides a timeline summary to clarify the sequence of events that took place between April 6 and April 28, 2020. Specific details related to analytical results, screening levels, and soil excavations are provided in Sections 4. 1 and 5.1 of this report.

3. 2. 1 Summary of Phasesof Hand-Auger Soil Sampling
The initial sampling event took place at the subject property on April 6, 2020. The purpose of this initial sampling event was to determine if residual pesticides or lead were present in soil as a result of former agricultural use and potential use of lead- based paint on the residence as identified in EEC's Phase I ESA dated March 18, 2020. Six hand auger borings ( B1 through B6) were advanced and soil samples were collected from 0. 5 and 3 feet bgs. The soil samples were submitted to Calscience and analyzed for OCPs and lead by USEPA Methods 8081A and 6010B.
53506. 02T, Huntington Beach, CA 3 99
Site Assessment Report June 25, 2020
Based on the results of the soil sampling, which identified elevated concentrations of lead and OCPs in B4 and B6, respectively, four additional hand- auger borings ( 67 through B10) were advanced on April 13, 2020 and soil samples were collected from 0. 5 and 3 feet bgs for additional site coverage. The soil samples were submitted to Calscience and analyzed for OCPs and lead by USEPA Methods 8081A and 6010B. Results of the April 13, 2020 soil sampling indicated that elevated concentrations of OCPs were found in B7, on the northwest portion of the subject property.

Due to the expeditious nature of the project, on April 13, 2020, soil at the location of borings B4 and B6 was excavated and soil samples were collected from confirmation borings at the sidewalls of the excavations ( 1315 through B18 around 134; B11 through B14 around 136) and submitted to Calscience for analysis of OCPs and lead by USEPA Methods 8081A and 60108. Elevated concentrations of OCPs and lead were not found in confirmation borings around B4 and B6, with the exception of boring 1311, which had elevated concentrations of OCPs. Approximately 1.39 cubic yards of material was removed from the location of boring B4 and approximately 1.39 cubic yards of material was removed from the location of boring B6.

Based on elevated concentrations of OCPs in B7 and 1311, step- out hand- auger borings were advanced adjacent to B7 ( 1329 through B32) and B11 ( B26 through B28) on April 16, 2020. Soil samples were collected from 0.5 and 3 feet bgs and submitted to Calscience for analysis of OCPs by USEPA Method 8081A. The only elevated concentrations of pesticides detected in the step- out borings were in B29 and B32, adjacent to boring location B7. The following additional tasks were planned to address the elevated concentrations of OCPs, but were not completed due to scope changes that occurred during the course of the project: excavation around B11 and excavation and confirmation soil sampling around B7, B29, and B32.

On April 27, 2020, the City of Huntington Beach entered into a Remedial Action Agreement with the OCHCA. The OCHCA indicated that select soil samples should also be analyzed for Title 22 Metals, mercury, hexavalent chromium, and herbicides. On April 29 and 30, 2020, soil samples from B4 and B6 through B10 were analyzed for California Title 22 metals by USEPA Method 6010B, mercury by USEPA Method 7471A, and hexavalent chromium by USEPA Method 7199 and soil samples from B7, B9, and B10 were analyzed for herbicides by USEPA Method 8151A. Because the laboratory hold time was exceeded, soil from B4 and B6 could not be analyzed for herbicides. Therefore, on April 28, 2020, hand- auger soil borings 134-A and 136-A were advanced near B4 and B6. Soil samples were collected from 0. 5 and 3 feet bgs and submitted to Calscience for analysis of herbicides by USEPA Method 8151A.

3. 3 Geoprobe Drilling and Soil and Groundwater Sampling Results of the additional soil analyses completed on April 29 and 30, 2020 indicated that elevated concentrations of hexavalent chromium were found in multiple soil samples at 0. 5 and 3 feet bgs. In order to better understand the lateral and vertical distribution of hexavalent chromium at the subject property, and to determine if groundwater was impacted, EECoversaw Strongarm Environmental Field Services, Inc. ( Strongarm) drill a total of 8 borings for the collection of soil and groundwater samples on May 11, 2020. The borings were placed in a grid pattern laterally over the subject property and close to previous boring locations; therefore, they were given similar nomenclature ( 131-A, 134-13, 135-A, 66- 13, 137- A, 138-A, 139-A, and B10- A; Figure 2).

The borings were advanced using Geoprobe direct- push drilling technology and hand-auger equipment.

Direct-push drilling rigs are hydraulically powered soil probing machines that use both static force and 53506. 02T, Huntington Beach, CA 4 1>CV59

percussion to drive steel boring rods into the subsurface. Before the initiation of drilling, Strongarm cleared the upper 5 feet of the borehole with a hand auger to verify the absence of underground utilities or other shallow obstructions.

A soil sample was collected from 4 feet bgs from each boring using the hand auger. The hand auger was removed from the borehole and an undisturbed soil sample was collected using a slide hammer sampler including a stainless steel sampling sleeve. Following sample retrieval, both ends of the sleeve were covered with a Teflon sheet and sealed with a plastic end cap. During direct- push drilling, continuous soil samples were collected using 5-foot long acetate sleeves. The direct- push rig hydraulically drove the sampling sleeve the entire 5-foot interval. Following sample retrieval the portion of the sleeve chosen for samples ( i. e., 5 feet bgs, 6 feet bgs, 7 feet bgs, and 8 feet bgs) was cut and the ends of each sample were covered with Teflon sheets and sealed with plastic end caps. Soil samples were then labeled with an identification number, sealed in a plastic bag, and placed into a chilled cooler.

An unused portion of soil from each sampling interval was used for field screening using a PID for evaluation of organic vapor content and for logging lithology. Field screening was conducted by placing a portion of the unpreserved soil in a sealable plastic bag for approximately 10 minutes. The organic vapor concentration in the headspace of the plastic bag was then measured using a PID. Soil descriptions and PID measurements were recorded and documented on field notes. All field activities were performed under the direct oversight of a California PG.

The collected soil samples were transferred under proper chain- of- custody protocols to Calscience and analyzed for hexavalent chromium by USEPA Method 7199, as shown on Table 3- 1 on Page 6 of this report.

3. 3. 1 Groundwater Sampling
Following soil sampling, groundwater samples were collected from three borings ( B4-B, B8-A, and B10- A). Groundwater samples were collected with a Hydropunch- type sampling device. The rod was withdrawn to expose the screen of the sampling device and a stainless steel bailer was then lowered into the borehole to collect a groundwater sample. Samples were labeled, sealed in a plastic bag, and placed into a chilled cooler. Collected groundwater samples were submitted to Calsciencefor analysis of hexavalent chromium by USEPA Method 218. 6.

4. 0 SAMPLING RESULTS

4. 1 Soil
A total of 86 soil samples were collected and analyzed for OCPs, herbicides, California Title 22 metals, lead, mercury, and hexavalent chromium between April 6 and May 11, 2020 ( Table 3- 1). The soil laboratory results are summarized below and in Table 1, Summary of Soil Analytical Results— Metals and Table 2, Summary of Soil Analytical Results — Pesticides and Herbicides. Estimated values ( J), detected below the reporting limit and above the laboratory method detection limit are included in the summary.

Analytical results were compared to the USEPA Regional Screening Levels ( RSLs) for residential soil and DTSC Screening Levels ( SLs) for residential soil ( Cleanup Standards). If both RSLs and SLs were available for a particular analyte, then the more stringent value was used. Laboratory analytical results, chain- of- custody documentation, and quality control data are provided in Appendix A, Laboratory Analytical Reports, Chain- of- Custody Record, and QA/ QC Data.

4. 1. 1 Metals
With the exception of lead and hexavalent chromium, metals detected in soil samples were at concentrations below their respective Cleanup Standard, or established background levels.

Lead was detected at 101 milligrams per kilogram ( mg/ kg) in 134-0.5, exceeding the Cleanup Standards. The deeper sample ( 3 feet bgs) collected from the same boring contained lead at a concentration of 2.81 mg/ kg, below Cleanup Standards; therefore, vertical delineation was achieved. Lead was not detected above Cleanup Standards in confirmation samples collected after excavation of soil around 64 ( Section 5. 1).

Hexavalent chromium was detected throughout the subject property at depths ranging from 0.5 feet bgs to 8 feet bgs. Concentrations ranged from 200 to 980 micrograms per kilogram ( µg/ kg), some of which exceeded Cleanup Standards.

4. 1. 2 Pesticides and Herbicides
Several organochlorine pesticides were detected in shallow soil, including 4, 4'- Dichlorodiphenyldichloroethane ( 4, 4'- DDD), 4, 4'- Dichlorodiphenyldichloroethylene ( 4- 4'- DDE), 4- 4' Dichlorodiphenyltrichloroethane ( 4, 4'- DDT), alpha- chlordane, chlordane, dieldrin, and toxaphene. All concentrations were below Cleanup Standards for residential soil, with the exception of toxaphene and 4, 4'- DDE. No other pesticides were detected above Cleanup Standards.

Toxaphene was detected in three samples ( 86- 0. 5, 67- 0. 5, and 610- 0. 5) at concentrations ranging between 500 µg/ kg and 1,600 µg/ kg, which exceeded the USEPARSLof 490 µg/ kg and DTSCSL of 450 µg/ kg. 4,4'- DDE was detected in one sample ( 137-0.5) at 3,100 µg/ kg, which exceeded the USEPA RSLof 2,000 jig/ kg ( DTSCSL not established).

Herbicides were not detected above laboratory reporting limits in any of the samples that were analyzed ( 64- A, 136-A, 137, 69, and B10 at 0. 5 and 3 feet bgs).

4. 2 Groundwater
On May 11, 2020, groundwater samples were collected from three of the geoprobe boring locations ( 138- A/ GW- 1, B4- B/ GW- 2, and B10- A/ GW- 3) in order to determine if hexavalent chromium in soil had impacted groundwater. Collected groundwater samples were transferred under proper chain- of- custody protocols to Calscience for analysis of hexavalent chromium by USEPA Method 218. 6.

Hexavalent chromium was not detected above the laboratory reporting limit of 0.038 micrograms per liter ( µg/ L) in any of the groundwater samples. It was detected at 0.086 J µg/ L in the equipment blank sample, which is laboratory- provided water used as a quality control sample.

5. 0 INVESTIGATION DERIVED WASTE AND EXCAVATED SOIL
Excavated soil, soil cuttings, and decontamination water generated during this assessment work were stored onsite in ten United States Department of Transportation ( DOT) approved 55- gallon drums. The drums were labeled documenting the accumulation start date, description of contents, and applicable contact information. Wastes will be profiled, manifested, and disposed of within 90 days of generation.

If available at the time of report preparation, the manifest( s) signed by the disposal facility will be included in the final report.

6. 0 CONCLUSIONS AND RECOMMENDATIONS
This site assessment and limited soil excavation was performed to address the findings of the Phase I ESA report. Based on the results of the site assessment and limited excavation activities, EEC has the following conclusions:

Soil impacted with lead, pesticides, and hexavalent chromium was found at the subject property.

Lead- impacted soil identified at the location of boring B4 was excavated and no additional investigation or excavation is warranted for lead impacts.

Pesticide- impacted soil at the location of boring B6 was partially excavated; however, multiple locations of elevated detections of pesticides remain at the subject property.

Hexavalent chromium was detected throughout the subject property at depths of up to 8 feet bgs; however, because hexavalent chromium was not detected in groundwater it appears to be a limited and isolated concern.

Based on the above conclusions, EEC recommends:

The ground surface at the subject property be covered with asphalt or concrete to eliminate the risk of dermal contact with soil at the subject property.

Any soil excavated from short- or long-term redevelopment be managed, handled, and disposed of in accordance with all regulatory requirements to minimize exposure to workers and the community.

Site Assessment Report June 25, 2020
If a change to use of the subject property occurs, the soil contamination must be addressed and additional assessment may also be required.

The OCHCA must be notified if there are any changes in site use and/ or if there are any future findings of additional contamination at the site.

The samples were received on 4/6/2020 2: 05 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 2. 70 C.

GC Semi VOA
Method 8081A: The matrix spike/ matrix spike duplicate( MS/ MSD) recoveries for the following sample associated with preparation batch 570- 61613 and analytical batch 570- 61652 were outside control limits: ( 570- 25057- A- 1- A MS) and ( 570- 25057- A- 1- B MSD). The associated laboratory control sample( LCS) recovery met acceptance criteria.

Method 8081A: The following samples has clear evidence of the presence of chlordane based on the presence of cis and trans chlordane; however, the chlordane peaks in the sample do not closely match the laboratory' s Technical Chlordane standard: 134-0.5( 570- 25057- 7) and 66- 0. 5( 570- 25057- 11). As a result, there is increased quantitative uncertainty associated with this result.

Method 8081A: The analyte 4, 4'- DDD was diluted due to the nature of the sample matrix: 136-0. 5( 570- 25057- 11) at 5X. Elevated reporting limits( RLs) are provided.

Receipt
The samples were received on 4/6/2020 2: 05 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 2. 71 C.

Metals
Method 6010B: The matrix spike/ matrix spike duplicate( MS/ MSD) recoveries for preparation batch 570- 62199 and analytical batch 570- 62245 were outside control limits. Sample matrix interference and/ or non- homogeneity are suspected because the associated laboratory control sample( LCS) recovery was within acceptance limits.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Receipt
The samples were received on 4/ 13/2020 2:07 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 2. 11 C.

GC Semi VOA
Method 8081A: The matrix spike, and matrix spike duplicate( MS/ MSD) associated with preparation batch 570- 62993 and analytical batch 570- 62847 were out of control limit. Due to the additional level of 4,4'- DDE and 4,4'- DDT present in the spiked samples, the concentration of 4, 4'- DDE and 4, 4'- DDT in the MS/ MSD was above the instrument calibration range.

Method 8081A: The matrix spike/ matrix spike duplicate( MS/ MSD) recoveries for preparation batch 570- 62993 and analytical batch 570- 62847 were outside control limits. Sample matrix interference and/ or non- homogeneity are suspected because the associated laboratory control sample( LCS) recovery was within acceptance limits.

Method 8081A: The continuing calibration verification ( CCV) associated with batch 570- 63013 recovered above the upper control limit for alpha- BHC and gamma- BHC. The samples associated with this CCV were non- detects for the affected analytes; therefore, the data have been reported.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Metals
No analytical or quality issues were noted, other than those described in the Definitions/ Glossary page.

Organic Prep
No analytical or quality issues were noted, other than those described in the Definitions/ Glossary page.
