11. PREVAILING WAGES.

A. Prevailing Wage. CONSULTANT is aware of the requirements of California Labor Code Section 1720, et seq., and 1770, et seq., as well as California Code of Regulations, Title 8, Section 16000, et seq., ("Prevailing Wage Laws"), which require the payment of prevailing wage rates and the performance of other requirements on "public works" and "maintenance" projects. If the services are being performed as part of an applicable "public works" or "maintenance" project, as defined by the Prevailing Wage Laws, and if the total compensation is $1,000 or more, CONSULTANT agrees to fully comply with such Prevailing Wage Laws.

Upon request, CITY shall provide CONSULTANT with a copy of the prevailing rates of per diem wages in effect at the commencement of this Agreement.

CONSULTANT shall make copies of the prevailing rates of per diem wages for each craft, classification or type of worker needed to execute the services available to interested parties upon request and shall post copies at the CONSULTANT’S principal place of business and at the project site. It is the intent of the parties to effectuate the requirements of sections 1771, 1774, 1775, 1776, 1777.5, 1813, and 1815 of the Labor Code within this Agreement, and CONSULTANT shall therefore comply with such Labor Code sections to the fullest extent required by law. CONSULTANT shall defend, indemnify and hold the CITY, its officials, officers, employees, agents, and volunteers free and harmless from any claim or liability arising out of any failure or alleged failure to comply with the Prevailing Wage Laws.

Page 4 of 13 ends

sole responsibility to comply with all applicable registration and labor compliance requirements, including the submission of payroll records directly to the DIR. Any stop orders issued by the DIR against CONSULTANT or any subconsultant that affect CONSULTANT’S performance of services, including any delay, shall be CONSULTANT’S sole responsibility. Any delay arising out of or resulting from such stop orders shall be considered CONSULTANT caused delay and shall not be compensable by CITY. CONSTRUCTION shall defend, indemnify and hold CITY, its officials, officers, employees and agents free and harmless from any claim or liability arising out of stop orders issued by the DIR against CONSULTANT or any subconsultant.

C. Labor Certification. By its signature hereunder, CONSULTANT certifies that it is aware of the provisions of Section 3700 of the California Labor Code which require every employer to be insured against liability for Worker's Compensation or to undertake self-insurance in accordance with the provisions of that Code and agrees to comply with such provisions before commencing the performance of the Services.

D. Employment of Apprentices. CONSULTANT and all subconsultants shall comply with the requirements of Labor Code sections 1777.5 and 1777.6 in the employment of apprentices. Information relative to apprenticeship standards, wage schedules, and other requirements may be obtained from the Director of Industrial Relations, ex officio the Administrator of Apprenticeship, San Francisco, California, or from the Division of Apprenticeship Standards and its branch offices.

E. CONSULTANT or subconsultants may not perform work on a public works project with a subconsultant who is ineligible to perform work on a public project pursuant to Labor Code section 1777.1 or 1777.7. Any contract on a public works project entered into between CONSULTANT and a debarred subconsultant is void as a matter of law. A debarred subconsultant may not receive any public money for performing work as a subconsultant on a public works contract. Any public money that is paid or may have been paid to a debarred subconsultant by CONSULTANT on the project shall be returned to CITY. CONSULTANT shall be responsible for the payment of wages to workers of a debarred subconsultant who has been allowed to work on the Project.

F. CONSULTANT agrees to bind every subconsultant to the terms of the Agreement as far as such terms are applicable to subconsultant’s portion of the work.

CONSULTANT shall be as fully responsible to CITY for the acts and omissions of its subconsultants and of persons either directly or indirectly employed by its subconsultants, as CONSULTANT is for acts and omissions of persons directly employed by CONSULTANT. Nothing contained in these Agreement shall create any contractual relationship between any subconsultant and CITY.

12. TERMINATION.

February 21, 2023, Reg CC Mtg., Page #199

Page 5 of 13 ends

A. Except as otherwise provided, CITY may terminate this Agreement at any time with or without cause. Notice of termination shall be in writing.

B. CONSULTANT may terminate this Agreement. Notice will be in writing at least 30 days before the effective termination date.

C. In the event of such termination, CONSULTANT shall cease services as of the date of termination, all finished or unfinished documents, data, drawings, maps, and other materials prepared by CONSULTANT shall, at CITY’s option, become CITY’s property, and CONSULTANT will receive just and equitable compensation for any work satisfactorily completed up to the effective date of notice of termination.

D. Should the Agreement be terminated pursuant to this Section, CITY may procure on its own terms services similar to those terminated.

13. INDEMNIFICATION.

A. CONSULTANT shall indemnify, defend with counsel approved by CITY, and hold harmless CITY, its officers, officials, employees and volunteers from and against all liability, loss, damage, expense, cost (including without limitation reasonable attorney’s fees, expert fees and all other costs and fees of litigation) of every nature arising out of or in connection with CONSULTANT's performance of work hereunder or its failure to comply with any of its obligations contained in this AGREEMENT, regardless of CITY’S passive negligence, but excepting such loss or damage which is caused by the sole active negligence or willful misconduct of CITY. Should CITY in its sole discretion find CONSULTANT’S legal counsel unacceptable, then CONSULTANT shall reimburse CITY its costs of defense, including without limitation reasonable attorneys fees, expert fees and all other costs and fees of litigation.

CONSULTANT shall promptly pay any final judgment rendered against CITY (and its officers, officials, employees and volunteers) covered by this indemnity obligation. It is expressly understood and agreed that the foregoing provisions are intended to be as broad and inclusive as is permitted by the law of the State of California and will survive termination of this Agreement.
i. If CONSULTANT’S obligation to defend, indemnify, and/or hold harmless arises out of CONSULTANT’S performance of “design professional” services (as that term is defined under Civil Code section 2782.8), then, and only to the extent required by Civil Code section 2782.8, which is fully incorporated herein, CONSULTANT’S indemnification obligation shall be limited to claims that arise out of, pertain to, or relate to the negligence, recklessness, or willful misconduct of CONSULTANT, and, upon CONSULTANT obtaining a final adjudication by a court of competent jurisdiction, CONSULTANT’S liability for such claim, including the cost to defend, shall not exceed CONSULTANT’S proportionate percentage of fault.

B. The requirements as to the types and limits of insurance coverage to be maintained by CONSULTANT as required by Section 18, and any approval of said insurance by CITY, are not intended to and will not in any manner limit or qualify the liabilities and obligations otherwise assumed by CONSULTANT pursuant to this Agreement, including, without limitation, to the provisions concerning indemnification.

14. ASSIGNABILITY. This Agreement is for CONSULTANT’s professional services.

CONSULTANT’s attempts to assign the benefits or burdens of this Agreement without CITY’s written approval are prohibited and will be null and void.

15. INDEPENDENT CONSULTANT. CITY and CONSULTANT agree that CONSULTANT will act as an independent CONSULTANT and will have control of all work and the manner in which it is performed. CONSULTANT will be free to contract for similar service to be performed for other employers while under contract with CITY. CONSULTANT is not an agent or employee of CITY and is not entitled to participate in any pension plan, insurance, bonus or similar benefits CITY provides for its employees. Any provision in this Agreement that may appear to give CITY the right to direct CONSULTANT as to the details of doing the work or to exercise a measure of control over the work means that CONSULTANT will follow the direction of the CITY as to end results of the work only.

16. AUDIT OF RECORDS.

A. CONSULTANT agrees that CITY, or designee, has the right to review, obtain, and copy all records pertaining to the performance of this Agreement. CONSULTANT agrees to provide CITY, or designee, with any relevant information requested and will permit CITY, or designee, access to its premises, upon reasonable notice, during normal business hours for the purpose of interviewing employees and inspecting and copying such books, records, accounts, and other material that may be relevant to a matter under investigation for the purpose of determining compliance with this Agreement. CONSULTANT further agrees to maintain such records for a period of three (3) years following final payment under this Agreement.

B. CONSULTANT will keep all books, records, accounts and documents pertaining to this Agreement separate from other activities unrelated to this Agreement.

17. CORRECTIVE MEASURES. CONSULTANT will promptly implement any corrective measures required by CITY regarding the requirements and obligations of this Agreement. CONSULTANT will be given a reasonable amount of time as determined by CITY to implement said corrective measures. Failure of CONSULTANT to implement required corrective measures shall result in immediate termination of this Agreement.

18. INSURANCE REQUIREMENTS.

A. CONSULTANT, at CONSULTANT’s own cost and expense, shall procure and February 21, 2023, Reg CC Mtg., Page #201

Page 7 of 13 ends

maintain, for the duration of the contract, the following insurance policies:

1. Workers Compensation Insurance as required by law. CONSULTANT shall require all subconsultants similarly to provide such compensation insurance for their respective employees. Any notice of cancellation or non-renewal of all Workers’ Compensation policies must be received by CITY at least thirty (30) days prior to such change. The insurer shall agree to waive all rights of subrogation against CITY, its officers, agents, employees, and volunteers for losses arising from work performed by CONSULTANT for CITY.

2. General Liability Coverage. CONSULTANT shall maintain commercial general liability insurance in an amount of not less than one million dollars ($1,000,000) per occurrence for bodily injury, personal injury, and property damage. If a commercial general liability insurance form or other form with a general aggregate limit is used, either the general aggregate limit shall apply separately to the work to be performed under this Agreement or the general aggregate limit shall be at least twice the required occurrence limit.

3. Automobile Liability Coverage. CONSULTANT shall maintain automobile liability insurance covering bodily injury and property damage for all activities of CONSULTANT arising out of or in connection with the work to be performed under this Agreement, including coverage for owned, hired, and non-owned vehicles, in an amount of not less than one million dollars ($1,000,000) combined single limit for each occurrence.

4. Professional Liability Coverage. CONSULTANT shall maintain professional liability insurance for protection against claims to the extent arising out of the negligent acts, errors, or omissions which may arise from CONSULTANT’S operations under this Agreement, whether such operations be by CONSULTANT or by its employees, subconsultants, or subconsultants. The amount of this insurance shall not be less than one million dollars ($1,000,000) on a claims-made annual aggregate basis, or a combined single-limit-peroccurrence basis. When coverage is provided on a “claims made basis,” CONSULTANT will continue to renew the insurance for a period of three (3) years after this Agreement expires or is terminated. Such insurance will have the same coverage and limits as the policy that was in effect during the term of this Agreement and will cover CONSULTANT for all claims made by CITY arising out of any negligent acts, errors or omissions of CONSULTANT, or its officers, employees or agents during the time this Agreement was in effect.

B. Endorsements. Each general liability, automobile liability and professional liability insurance policy shall be issued by a financially responsible insurance company or companies admitted and authorized to do business in the State of California, or which is approved in writing by CITY, and shall be endorsed as follows.

CONSULTANT also agrees to require all CONSULTANTs, and subconsultants to do likewise.

February 21, 2023, Reg CC Mtg., Page #202

Page 8 of 13 ends

1. “The CITY, its elected or appointed officers, officials, employees, agents, and volunteers are to be covered as additional insureds with respect to the commercial general liability and automobile liability arising out of work performed by or on behalf of the CONSULTANT, including materials, parts, or equipment furnished in connection with such work or operations.”

2. The commercial general liability and automobile liability policy shall be considered primary insurance as respects CITY, its elected or appointed officers, officials, employees, agents, and volunteers. Any insurance maintained by CITY, including any self-insured retention CITY may have, shall be considered excess insurance only and shall not contribute with this policy.

3. This insurance shall act for each insured and additional insured as though a separate policy had been written for each, except with respect to the limits of liability of the insuring company.

4. The insurer waives all rights of subrogation against CITY, its elected or appointed officers, officials, employees, or agents.

5. Any failure to comply with reporting provisions of the policies shall not affect coverage provided to CITY, its elected or appointed officers, officials, employees, agents, or volunteers.

6. The insurance provided by this policy shall not be suspended, voided, canceled, or reduced in coverage or in limits to not meet the requirements of this Agreement except after thirty (30) days’ written notice has been received by CITY.

C. CONSULTANT agrees to provide prompt notice to CITY of any claim or loss against CONSULTANT arising out of the work performed under this agreement.

CITY assumes no obligation or liability by such notice, but has the right (but not the duty) to monitor the handling of any such claim or claims if they are likely to involve CITY.

D. Any deductibles or self-insured retentions must be declared to and approved by CITY. At CITY’s option, CONSULTANT shall demonstrate financial capability for payment of such deductibles or self-insured retentions.

E. CONSULTANT shall provide certificates of insurance with original endorsements to CITY as evidence of the insurance coverage required herein. Certificates of such insurance shall be filed with CITY on or before commencement of performance of this Agreement. Current certification of insurance shall be kept on file with CITY at all times during the term of this Agreement.

F. Failure on the part of CONSULTANT to procure or maintain required insurance February 21, 2023, Reg CC Mtg., Page #203

Page 9 of 13 ends

shall constitute a material breach of contract under which CITY may terminate this Agreement pursuant to Section 11 above.

G. The commercial general and automobile liability policies required by this Agreement shall allow CITY, as additional insured, to satisfy the self-insured retention (“SIR”) and/or deductible of the policy in lieu of the CONSULTANT (as the named insured) should CONSULTANT fail to pay the SIR or deductible requirements. The amount of the SIR or deductible shall be subject to the approval of the City Attorney and the Finance Director. CONSULTANT understands and agrees that satisfaction of this requirement is an express condition precedent to the effectiveness of this Agreement. Failure by CONSULTANT as primary insured to pay its SIR or deductible constitutes a material breach of this Agreement. Should CITY pay the SIR or deductible on CONSULTANT’S behalf upon CONSULTANT’S failure or refusal to do so in order to secure defense and indemnification as an additional insured under the policy, CITY may include such amounts as damages in any action against CONSULTANT for breach of this Agreement in addition to any other damages incurred by CITY due to the breach.

19. USE OF OTHER CONSULTANTS. CONSULTANT must obtain CITY’s prior written approval to use any CONSULTANTs while performing any portion of this Agreement.

Such approval must include approval of the proposed CONSULTANT and the terms of compensation.

20. FINAL PAYMENT ACCEPTANCE CONSTITUTES RELEASE. The acceptance by the CONSULTANT of the final payment made under this Agreement shall operate as and be a release of CITY from all claims and liabilities for compensation to the CONSULTANT for anything done, furnished or relating to the CONSULTANT’S work or services. Acceptance of payment shall be any negotiation of CITY’S check or the failure to make a written extra compensation claim within ten (10) calendar days of the receipt of that check. However, approval or payment by CITY shall not constitute, nor be deemed, a release of the responsibility and liability of CONSULTANT, its employees, sub-CONSULTANTs and agents for the accuracy and competency of the information provided and/or work performed; nor shall such approval or payment be deemed to be an assumption of such responsibility or liability by CITY for any defect or error in the work prepared by CONSULTANT, its employees, sub-CONSULTANTs and agents.

21. CORRECTIONS. In addition to the above indemnification obligations, the CONSULTANT shall correct, at its expense, all errors in the work which may be disclosed during CITY’S review of CONSULTANT’S report or plans. Should the CONSULTANT fail to make such correction in a reasonably timely manner, such correction shall be made by CITY, and the cost thereof shall be charged to CONSULTANT. In addition to all other available remedies, CITY may deduct the cost of such correction from any retention amount held by CITY or may withhold payment February 21, 2023, Reg CC Mtg., Page #204

Page 10 of 13 ends

otherwise owed CONSULTANT under this Agreement up to the amount of the cost of correction.

22. NON-APPROPRIATION OF FUNDS. Payments to be made to CONSULTANT by CITY for services preformed within the current fiscal year are within the current fiscal budget and within an available, unexhausted fund. In the event that CITY does not appropriate sufficient funds for payment of CONSULTANT’S services beyond the current fiscal year, the Agreement shall cover payment for CONSULTANT’S only to the conclusion of the last fiscal year in which CITY appropriates sufficient funds and shall automatically terminate at the conclusion of such fiscal year.

1 SECTION I

GENERAL INFORMATION
A. INTRODUCTION / BACKGROUND
The City of Lomita is requesting proposals from qualified and experienced Civil Engineering firm(s) to provide a feasibility study and report for to determine suitable locations for a new groundwater production well.

The City of Lomita is an urban, densely populated 1.97 square miles (total area is 1,261 acres), located at the base of the Palos Verdes Peninsula in the Los Angeles Basin, Los Angeles County. The City of Lomita is located in the southwestern part of Los Angeles County, 26 miles south of downtown Los Angeles and bounded by the City of Torrance on the north and west, the Harbor Region of Los Angeles to the east, and the City of Rolling Hill Estates on the southwest; and the City of Rancho Palos Verdes and unincorporated Los Angeles County area to the southeast. The City is almost completely developed with mostly residential neighborhoods and commercial units.

The City’s water system has one (1) groundwater source well with approximate production capability of 1,500 gallon per minute (GPM), two reservoirs with combined capacity over 5.4 million gallons, and two (2) pressure reducing stations (Appian Way and Monte Vista Pressure Reducing Station). The City’s groundwater well (Well No. 5), located within the Silverado Aquifer, has a depth of 660 feet and is a main component of the Cypress Water Production Facility (CWPF). The CWPF treats Well No. 5 groundwater with an iron-manganese greensand filtration, chlorination, and newly installed granular activated carbon treatment system. The purpose of this treatment system is for disinfection, to remove iron, manganese, and volatile organic compounds, and improve aesthetic qualities.

In 2018, approximately 28% of total water volume delivered to its residents was from Well No. 5, and the remaining 72% was imported from Metropolitan Water District (MWD). Due to the detection of benzene at Well No. 5, the City has been solely reliant on MWD water since May 2019. Lomita Well No. 5 and the CWPF are anticipated to remain offline until construction completes adding granulated activated carbon treatment to the system’s process in early 2023.

In August 2022, the City completed a study that evaluated Skypark Commercial Properties (SCP) impact on groundwater contaminants migrating to Lomita Well No. 5 (see Attachment C). The study area encompassed the SCP sources in the City of Torrance and Lomita within the West Coast Basin, a sub-basin of the Los Angeles Basin. The study concluded that that the benzene impacting Lomita Well No.5 traveled from a near surface source. This finding indicated that Silverado Aquifer, in areas near the well, is vulnerable to vertical downward migration of potential February 21, 2023, Reg CC Mtg., Page #211
2 chlorinated volatile organic compounds (cVOCs) impacts. The main cVOCs of concern affecting the area, and likely to affect siting a new well installation are Trichloroethene (TCE) and Tetrachloroethene (PCE). Due to the limited information outside of the SCPs and the lack of monitoring wells in the area, groundwater flow and all historical and/or future contaminants may not have been identified to date.

B. PROJECT DESCRIPTION

The New Groundwater Well Feasibility Study was included in the City of Lomita CIP Master Plan. The purpose of this study is to minimize the City’s long-term reliance on imported water and provide a contingency well in case of future adverse impacts to Lomita Well No. 5. The City currently has groundwater rights of 1,352-acre feet (ac-ft) in the West Coast Basin. In its last year of normal operations, CY 2018, Well No. 5 produced 561 ac-ft of groundwater. In the past, CWPF blended well-treated water with imported water at ratios of 40%-60%. The blending ratio was established for aesthetic purposes. Additionally, CWPF only supplies Zone 1, approximately 66% of the city. Future studies may consider supplying Zones 2 and 3 by CWPF. The goal of this Study is to identify preliminary locations where a new groundwater source well installation would be feasible. Recommended well locations may be in City limits or neighboring cities.

High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 1 Rev 1: 318160-40240-WW-REP-0001
1 Introduction
The City of Lomita (the City) contracted Worley Group Inc., operating as Advisian, to conduct a high-level assessment of potential future impacts of chlorinated volatile organic compounds (cVOCs) in groundwater, originating from the Skypark Commercial Properties (the SCPs), on the City’s sole groundwater production well (Lomita Well #5). The locations of the SCPs and Lomita Well #5 is shown in Figure 1-1.

The SCPs include several properties located within a single assessor parcel number (APN No. 7377-006- 906) which is in and owned by the City of Torrance, located approximately 1.25 miles northwest (hydraulically upgradient) of Lomita Well #5.

The SCPs have been under investigation under the oversight of the Regional Water Quality Control Board (RWQCB) since at least 1991, and specifically since 2009 under a California Water Code Section 13267 Investigative Order, to delineate the lateral and vertical extent of cVOCs (i.e., trichloroethene [TCE], tetrachloroethene [PCE], dichloroethene [DCE] and vinyl chloride [VC]), in soil, soil vapor and groundwater.

To date, cVOC impacts have been reported within the Gage aquifer, a regional water table aquifer (RWTA) that is an important water bearing zone in the area. A cVOC plume in groundwater is interpreted to be migrating east-southeast with the RWTA beneath residential properties located east of Crenshaw Boulevard in Lomita, California.

This report provides an overview of the conceptual site model (CSM) and subsequent analytical modelling used to evaluate the long-term fate and transport of cVOCs from the SCPs and potential future impacts on Lomita Well #5.

2 Conceptual Site Model
This section contains an overview of the CSM for the Project Area (refer to Figure 1-1). The CSM is based on publicly available data and has been developed to include descriptions of the environmental setting, potential sources, contaminants of concern (COCs), contaminant fate and transport processes and pathways, and potential receptors.

The information summarized below is not intended to provide a comprehensive description of the SCPs or include all historical activities, but to provide context for the CSM that provided the basis of the evaluation herein.

Additional information on environmental conditions and site characterization associated with the SCPs has been documented by numerous authors including the consulting firms Hygienetics, Inc. (1991), SCS Engineers (1991a, 1991b and 1992), Camp Dresser & McGee (1991), Geosyntec Consultants (1995), BBL Environmental Services Inc. (BBL; 2000 and 2001), Environmental Engineering & Contracting, Inc. (EEC; 2008), Winefield & Associates (2010) Alta Environmental (Alta; 2013), Terraphase (2022a and 2022b), and Genesis Engineering and Redevelopment (2021). Historical reports are maintained on the State Water Resources Control Board (SWRCB) GeoTracker website (SWRCB 2022).

Site Location and Land Use
The Project Area encompasses both the City of Torrance (where the SCPs are located) and the City of Lomita (where Lomita Well #5 is located). The Project Area is located in southern Los Angeles County, California, approximately 15 miles south-southwest of downtown Los Angeles.

Land use within the vicinity of the SCPs is a mix of commercial and industrial use and contains the Torrance Municipal Airport. The SCPs are bordered by Skypark Drive on the north, the Pacific Coast Highway on the south and Crenshaw Boulevard to the east. Residential communities within the City are located east and southeast of Crenshaw Boulevard.

As indicated in the City of Lomita Water Master Plan Update (KEC Engineers, Inc. [KEC] 2015), Lomita Well #5 is located at 26112 Cypress Street, Lomita, California, approximately 1.25 miles southeast of the SCPs, as shown on Figure 1-1. The well is the main component of the Cypress Water Production Facility and is located in an area which includes a mixture of commercial and residential properties.

Historical Site Information
The SCPs comprise an approximately 12.25-acre property that is owned by the City of Torrance and has reportedly been occupied by Hi-Shear Corporation (Hi-Shear) and other parties since at least 1954.

Hi-Shear’s primary business is understood to be the manufacture of metal fasteners used in the aerospace industry (BBJ Group and Ramboll 2021 and GE&R 2021a).

Various subsurface features are reported to have existed at the SCPs, including underground storage tanks (USTs) and clarifiers (which included storage of TCE-containing solvents), an industrial wastewater treatment plant, and various above ground storage tanks for plating operations. Historical records also February 21, 2023, Reg CC Mtg., Page #237
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 4 Rev 1: 318160-40240-WW-REP-0001
indicate that Hi-Shear had degreasing units that used PCE, and several spray booths for paints and solvents. Annual Toxic Release Inventory (TRI) Form R reports also indicate that several chemicals (including PCE, TCE, and 1,1,1-Trichloroethane [1,1,1-TCA]) were used at the SCPs (Hygienics 1991; BBJ Group and Ramboll 2021).

The SCPs have been subject to environmental site assessments and investigations since at least 1991, according to records (SWRCB 2022) that indicate a Phase I Environmental Site Assessment was performed by Hygienetics, Inc. in May 1991. The earliest soil and groundwater investigations were performed by Camp Dresser & McKee, Inc. (1991) and SCS Engineers (1991), both of whom reported cVOCs impacts to the shallow soil and groundwater system. The primary COCs include TCE and PCE. Several subsequent site investigations conducted at the SCPs confirmed cVOCs impacts to soil, soil vapor, and groundwater (perched and regional) and aimed to delineate the vertical and lateral extent of contamination, as summarized by BBL (2001), EEC (2008), Winefield & Associates (2010), and GE&R (2021a & b).

In addition to environmental investigation activities, various remediation approaches including soil vapor extraction (SVE) (intermittently since at least 1999 [BBL 2000] and recently restarted), and groundwater remediation (with various phases from pilot to full-scale studies between approximately 2012 and 2017) have been implemented at the SCPs (Alta 2017; Terraphase 2022a and 2022b).

While some source removal of cVOCs has occurred, a groundwater plume remains on-site that extends downgradient from the source area at the SCPs to the east-southeast beneath neighboring properties in the City of Lomita (GE&R 2021a and MK Environmental 2021).

Regional Geologic Setting
The Project Area is located within the West Coast Basin, a sub-basin of the Los Angeles Basin. The West Coast Basin encompasses approximately 140 square miles, extending from the Pacific Ocean southeast to the Palos Verdes Hills, San Pedro Bay, and Orange County (California Department of Water Resources [CDWR] 1961). The West Coast Basin is separated from the Central Basin to the east by the NewportInglewood uplift, a regional anticlinal fold, which extends approximately 40-miles southeast from Beverly Hills to Newport Beach (USGS 2003).

The West Coast Basin contains a series of aquifers and aquicludes. Aquifers are composed of thick, permeable sediments that are a source of water to groundwater wells. The term “aquiclude” describes the less permeable silt and clay layers that separate the aquifers in some locations. The shallowest groundwater underneath the Project Area is an unconfined semi-perched aquifer. This semi-perched aquifer is composed of Recent age marine and estuarine deposits. Beneath the semi-perched aquifer is the Bellflower Aquiclude. Regionally, the Bellflower Aquiclude is approximately 100 to 120 feet (ft) thick and composed of finer-grained sediments (clay, silt, sandy silt, silty sand, clayey sand, sandy clay, and gravelly clay). Where the Bellflower Aquiclude is found, the finer-grained sediments inhibit groundwater movement between the semi-perched aquifer and the underlying Gage Aquifer.

The semi-perched aquifer is underlain by the Upper Pleistocene marine and nonmarine alluvial terrace deposits of the Lakewood Formation, a heterogenous unit dominated by sandy silts and silty sands interbedded with varying thicknesses of sand. The entire Lakewood aquifer system ranges in thickness from 150 to 400 ft and includes the Gage Aquifer system (USGS 2003). The Gage Aquifer is the regional February 21, 2023, Reg CC Mtg., Page #238
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 5 Rev 1: 318160-40240-WW-REP-0001
water table aquifer (RWTA) which underlies the Project Area. It is approximately 200 ft thick near the SCPs and regionally consists primarily of sand with trace amounts of gravel and thin beds of silt and clay.

According to geologic reports, the Bellflower Aquiclude may be absent in the vicinity of the Project Area and aquifers present are thought to be in hydraulic continuity with the surface (CDWR 1961).

The Lakewood Formation is underlain by the Lower Pleistocene San Pedro Formation, which is underlain by the Pliocene Pico Formation. The San Pedro Formation includes the Silverado Aquifer. The uppermost portion of the San Pedro Formation consists of a clay layer between 40 to 100 ft thick which separates the Gage Aquifer and underlying Silverado Aquifer. Although Alta (2012) reports that the clay layer may be locally absent in the Torrance area as noted by Hargis and Associates (1991) in BBL (2002). Reportedly, in this area the Gage and Silverado Aquifers appear to merge. The Silverado Aquifer, the lowermost aquifer of the San Pedro aquifer system, produces the most water in the system and is estimated to be between 250 and 500 ft below the SCPs. The Pico Formation is composed of mostly marine sediments which include interbedded layers of sandstones, siltstones, and mudstones (CDWR 1961).

The Pico Formation is underlain by the Miocene Monterey Shale and Puente Formation. Basement rock beneath this sedimentary sequence is the Catalina schist facies of the Franciscan Formation.

A summary of the regional geological stratigraphy is shown in Table 2-1.

A review of Bulletin 104 (CDWR 1961) indicates that the RWTA is interpreted to be within the Gage Aquifer. The review suggests a depth to the top of the Gage Aquifer of approximately 60 ft. The RWTA was February 21, 2023, Reg CC Mtg., Page #239
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 6 Rev 1: 318160-40240-WW-REP-0001
encountered during site investigations at the SCPs at approximately 80 to 90 ft below ground surface (bgs) (BBL 2002; Alta 2013; and GE&R 2021a & b) and at 133 to 138 ft bgs near Lomita Well #5 (ETIC 2020 and PIC 2022). Near the SCPs, the RWTA is known to extend to a depth of at least 285 ft bgs, indicating a saturated thickness of at least 190 ft (Alta 2013).

As shown on Figure 2-1, groundwater flow in the RWTA is generally towards the east-southeast direction with a horizontal hydraulic gradient between 0.0008 to 0.004 (with an average of 0.0021) as reported in Alta (2017) and GE&R (2021). The regional groundwater flow direction has not changed since monitoring began (in 1991) and is thought to be impacted by injection of water to the west via the West Coast Barrier Basin Project (WCBBP) and regional groundwater extraction southeast of the SCPs (Alta 2013 and GE&R 2021a). Injection wells in the WCBBP create a north-south trending mound of fresh water from the Los Angeles International Airport area, south to the Palos Verdes Hills. Injection wells also form a protective mound at the Dominguez Gap Barrier located southeast of the Project Area near Wilmington (CDWR 2021).

Figure 2-1 Groundwater Flow in the Gage (RWTA) Aquifer
The Water Replenishment District (WRD) has one nested monitoring well (Lomita #1) within the Project Area. There are six individual zones that are screened as part of the nested monitoring well, including screens installed within (from shallowest to deepest): the Gage (two zones), Lynwood, Silverado (two zones) and Pico Aquifers. Screen depths range from 120 to 1260 ft bgs (WRD 2021). Historically, water February 21, 2023, Reg CC Mtg., Page #240
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 7 Rev 1: 318160-40240-WW-REP-0001
levels in the Silverado Aquifer are generally deeper than those of the Gage Aquifer by approximately 1 to 4 ft (WRD 2021).

In 2002, BBL reported that the vertical groundwater flow gradient in the RWTA observed in cluster wells was directed downward; however, more recent data (Geosyntec 2010) for the cluster wells are inconclusive.

A review of TCE concentrations in one well cluster (BBL 2002) also suggested that chlorinated solvents are primarily migrating laterally through the RWTA versus vertically.

A conceptual model of the hydrogeological setting is shown as Figure 2-2.

Lomita Well #5
The City of Lomita’s only groundwater production well (Lomita Well #5) is located approximately 1.25 miles southeast of the SCPs. Lomita Well #5 was drilled and completed in January 1971, with an approximate production capacity of 1,500 gallons per minute (gpm; Dudek 2022). The well is 660 ft deep and is perforated from 368 to 648 ft bgs within the Silverado Aquifer (KEC 2015). The City currently has adjudicated rights of 1,352 acre-feet of groundwater, annually (WRD 2021a).

In 2018, the Los Angeles Regional Board received notification of a benzene detection in Lomita Well #5.

Analytical testing data from Lomita Well #5 reported concentrations of benzene at 0.54 micrograms per liter (µg/L) in May 2018, 3.2 µg/L in April 2019, and 3.7 µg/L in May 2019, and Lomita Well #5 was subsequently taken off-line. The Los Angeles Regional Board has initiated an investigation to identify the source(s) of benzene impacting Lomita Well #5. Investigations of USTs that were used to store gasoline at several sites located hydraulically upgradient from Lomita Well # 5 haven recently been undertaken; however, to date, the source(s) of benzene in the Silverado Aquifer has not been determined (ETIC 2020 and PIC Environmental Services [PIC] 2022).

Contaminants of Concern (COCs)
Substantial releases of cVOCs (specifically PCE and TCE) have occurred within the SCPs due to activities and infrastructure at the site which have impacted soil, soil vapor and groundwater. Degradation products of PCE and TCE, including cis-1,2-dichloroethene (cis-1,2-DCE), trans-1,2-dichloroethene (trans-1,2-DCE), 1,1-dichloroethene (1,1-DCE) and vinyl chloride (VC) have also been detected above respective screening levels in groundwater. In 1991, the first reported groundwater well (MW-1) was installed within the RWTA at the SCPs. Reported concentrations of PCE, TCE, and 1,1-DCE were 220, 6,600, and 20 µg/L, respectively (Hygienetics 1991).

Since 1991, a number of site investigations have been performed to delineate the source concentration area(s) and plume migration over time. Historical site investigations have consistently shown that cVOCs within the RWTA have migrated as a co-mingled plume east-southeast from the SCPs impacting downgradient properties east of Crenshaw Boulevard (Winefield & Associates 2010; Alta 2016; and GE&R 2021a).

A summary of PCE and TCE concentrations and iso-concentration contours are shown on Figure 2-3. The figure is based on recent data (from November 2019) showing the area of groundwater impacted beneath and downgradient of the SCPs beneath the City of Lomita, east of Crenshaw Boulevard (GE&R 2021a).

As shown on Figure 2-3, PCE and TCE concentrations in the RWTA progressively decrease with depth to concentrations below the maximum contaminant level (MCL) of 5 µg/L at approximately 150 ft bgs. No impacts to the Silverado Aquifer have been reported to date. However, the number of wells installed in this aquifer are limited in the Project Area.

3 Modelling Methodology
BIOCHLOR Model
The analytical model BIOCHLOR (version 2.2), developed by the United States Environmental Protection Agency (USEPA 2000 and 2002), was used to model the fate and transport of cVOCs in the Project Area.

BIOCHLOR is designed to solve the problem of solute transport in uniform (one dimensional, steady state) groundwater flow.

In BIOCHLOR, solute transport is analytically solved using the modified Domenico model (Domenico 1987) with first order biotransformation and source decay. Mechanisms for the transport of solute include advection and three-dimensional dispersion, sorption of the solute onto soil, and biotransformation of the solute from parent to daughter compound via first order decay. BIOCHLOR is specifically designed to model the fate and transport of chlorinated solvents through sequential decay (i.e., the PCE-TCE-DCE-VC sequence).

Biodegradation is an important process in the natural attenuation of chlorinated solvents. The majority of solvent biodegradation occurs by reductive dechlorination (Wiedemeier et al. 1996) as shown in Figure 3-1. Evidence of plume mass reduction is noted at the SCPs through the decreasing abundance of parent compounds (TCE or DCE) relative to degradation products (DCE and VC) at downgradient locations which indicates biodegradation is likely occurring (GE&R 2021a).

Figure 3-1 Reaction Sequence of Chlorinated Ethenes (from Parsons 2004) For the BIOCHLOR model to be applicable, the following key assumptions must be met:
• Uniform Flow: The plume must be contained within a volume of porous media such that the groundwater velocity and dispersivity are relatively constant (i.e., within a single aquifer versus multiple aquifers). In general, this condition is met as the plume is thought to be migrating primarily within the Gage Aquifer (i.e., the RWTA).
• Known Source: A source of known size of sufficient mass to the groundwater flow field so as to maintain constant concentration. Although the size and concentration of the initial source area is unknown, there is sufficient data over a significant timeframe (1991 to 2021) to characterize the source area for the purposes of the evaluation herein.
• First Order Decay Kinetics: The compounds under consideration must transform as a decay chain with first-order kinetics. This is a reasonable assumption for chlorinated solvents. Degradation February 21, 2023, Reg CC Mtg., Page #244
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 11 Rev 1: 318160-40240-WW-REP-0001
coefficients can be selected via the process of model calibration to calibrate to measured solute concentrations.
• Advection Transport: It is assumed within BIOCHLOR that advection is the dominant transport mechanism for cVOCs in groundwater at the Site.

The BIOCHLOR model cannot mathematically accommodate and simulate a single contaminant source both before and after mass-removal remediation (within the same model). The model therefore assumes a non-remediated source, incorporating PCE concentrations at the source which reflect aquifer conditions prior to removal of the contaminant source material. In this manner, the model presents a conservative simulation as it does not account for any reduction in cVOC concentrations that might be realized from historical or proposed removal actions.

3.1.1 BIOCHLOR Model Input Parameters
A summary of all model input parameters is provided in Appendix A and discussed below.

Model Domain and Simulation Timeframe
A definitive source of cVOCs has not been identified; however, data from as early as 1991 indicates that cVOCs were identified within the shallow groundwater system at that time (Hygienetics 1991 and BBL SCS Engineers 1991). It is possible that the cVOCs could date back to a time significantly earlier than 1991 (e.g., manufacturing activities have been occurring at the SCPs since 1954) and therefore, a simulation time of 100 years was initially selected to simulate steady-state conditions.

One source area was modelled for the CSPs based on the CSM. The model source area was configured as a single-planar source the width of the groundwater plume (approximately 280 ft, based on current plume maps; GE&R 2021a) and the thickness of the RWTA interval (190 ft). A modelled area width and length of 280 and 5,000 ft, respectively, was simulated.

It is noted that the width is not necessarily critical to the modeling outcome as the modelling is used to simulate the maximum concentrations along the centerline of the plume (i.e., along the axis of the wells for which the data are modelled).

Hydrogeology
The hydraulic gradient (i) within the source area was estimated from groundwater levels measured between 2013 and 2019 (GE&R 2021a). The groundwater flow direction (east to southeast) and hydraulic gradient have remained relatively unchanged since groundwater monitoring began in 1991 based on the available data. An average hydraulic gradient of 0.0021 ft/ft was used for all simulations (as noted in Section 2.4).

Aquifer tests at the SCPs have yielded hydraulic conductivity (K) values that range in magnitude from 2.4 to 4 ft/day (BBL 2002) up to 46 to 58 ft/day (Alta 2013). The modelled K-values were varied over two orders of magnitude within a range consistent with reported values. An assumed effective porosity (ne) consistent with that of silty sands to clean sands (0.25; Gibb et al. 1984) was used for all simulations.

February 21, 2023, Reg CC Mtg., Page #245
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 12 Rev 1: 318160-40240-WW-REP-0001
As discussed above, the mean K, I, and ne values were used as inputs to the model to determine seepage velocity (v).

Dispersion
Dispersion was calculated in the model based on the observed length of the plume using data from November 2019 (GE&R 2021a). Concentrations of TCE and PCE were observed downgradient of the assumed source area in shallow monitoring wells MW-28 (49 μg/L) and MW-21 (41 μg/L) but were not detected in monitoring wells MW-25, MW-27, MW-26, or MW-36 (all located along Pennsylvania Avenue).

Based on the reported non-detectable concentrations at these wells from 2019 data (GE&R 2021), a plume length of approximately 2,000 ft was estimated for the purposes of this evaluation.

A fixed value for the longitudinal dispersivity (10 percent of the plume length), based on data summarized in Aziz et al. (2000), was employed. Transverse dispersivity was assumed to be 30 percent (0.30) and vertical dispersivity was assumed to be five percent (0.05) of the longitudinal dispersivity, respectively (Aziz and Newell 2002).

Rate Constants (Adsorption and Biotransformation)
Source area concentrations are expected to decrease through mass lost due to advection out of the source area, volatilization, and chemical and biologic degradation processes. A non-decaying source area was used in the BIOCHLOR. Source decay is described by a constant (ks) and accounts for all of the processes that reduce the source area concentration and is different from the biodegradation rate (λ), which only addresses the rate of biologic transformation.

Biodegradation rate constants were estimated using literature data and field data from existing monitoring wells (e.g., MW-18, MW-12, MW-28, and MW-36). These wells were used to define the approximate plume centerline, as shown on Figure 3-2. Rate constants were estimated through calibration of the BIOCHLOR model to cVOC concentration data from monitoring wells near the plume centerline. As field data to date indicates that only the Gage (RWTA) aquifer has been impacted, only cVOC data from RWTA wells were used. In addition, data were used only from wells in the part of the plume deemed to be anaerobic (i.e., dissolved oxygen values less than 1 mg/L).

To define a model retardation factor for the modeled cVOCs, the retardation factor was calculated within BIOCHLOR based on the soil bulk density, fraction organic carbon (Foc), and partition coefficient values. All parameters were initially assumed based on literature values as defined in Appendix A. As noted above, rate constants were estimated by adjusting values within literature ranges until the BIOCHLOR concentration predictions reasonably matched the field data.

Figure 3-2 Conceptual Diagram of BIOCHLOR Model Setup and Calibration Data Source Area Concentrations and Field Data
Source area concentrations were based on data provided in the initial site investigation reports (Hygienetics 1991 and CDM 1991). A single monitoring well (MW-1) was installed within the RWTA and reported concentrations were above referenced guideline values for PCE (220 μg/L), TCE (6,600 μg/L), 1,1,1-TCA (6 μg/L), and 1,1-DCE (20 μg/L). For this evaluation, it is assumed that the initial source concentrations would be similar to (or within an order of magnitude) to the values reported in 1991 at MW-1.

Field data from the most recent site conceptual model report (GE&R 2021a) were used to calibrate the model. Concentrations of PCE, TCE, DCE and VC at monitoring wells MW-18 (proximal to the assumed source area), MW-12 (750 ft), MW-28 (1,500 ft), and MW-36 (2,425 ft), located downgradient of the assumed source area and along the plume centerline, as reported in GE&R (2021a) were used to calibrate the model.

3.1.2 Model Calibration
Model calibration involved finding a set of fate and transport parameters that result in the BIOCHLOR model output producing a reasonable match to the plume concentration distribution as measured in the field. The BIOCHLOR model was calibrated using a deterministic approach to represent current site conditions assuming steady-state groundwater flow. It is noted that the model calibration does not account for active groundwater remediation that has occurred on site but does account for biodegradation of the source.

PCE and TCE are considered the primary COCs and therefore the model calibration focused on the PCE and TCE plumes. To represent current site conditions, PCE and TCE concentration data from monitoring wells located within the assumed source area and along the centerline axis of the plume (MW-18, MW-12, MW-28, and MW-36) were used to compare against the simulation results.

Adjustments were made to the seepage velocity parameters (i.e., K and i) within range of reported values and the biotransformation (degradation) rates were adjusted for each cVOC.

For PCE, the match between simulated and observed concentrations indicate the model is generally able to reproduce field conditions under the given assumptions.

For TCE, during the initial calibration process, there was discrepancy between the model results and field data. In reviewing the model results and field data it became apparent that reported concentrations of TCE at MW-1 in 1991 (6,600 μg/L) were two orders of magnitude lower than reported concentrations at MW-3 (25,000 μg/L) in 2001 (BBL 2001), which is an indication that the original source concentration was likely much higher than that reported in 1991 or that there is more than one contributing source. Thus, the source concentration value for TCE in BIOCHLOR was increased to 70 mg/L which provided a better fit to the TCE field data.

It is noted that the model generally overestimates biodegradation in the area of the plume near the source zone and underestimates biodegradation at the leading edge of the plume. This suggests that the modelled biodegradation rate may be higher than is actually occurring in some areas or that previous remediation activities at the SCPs have affected TCE concentrations (which is to be expected). It is also noted, the TCE degradation rate used during the model runs is an averaged estimate for the entire plume; however, because the plume is heterogeneous in terms of the degradation rate in different portions of the plume, this averaged estimate is associated with some degree of uncertainty. The uncertainties in other transport parameters (e.g., use of an average K value and hydraulic gradient for the entire site when in reality heterogeneities exist) could also cause the difference between simulated and observed concentrations of TCE.

3.1.3 Sensitivity Analysis and Verification
Sensitivity analysis of the model was performed to assess the variation in results within a reasonable range of input parameters. Sensitivity analyses were conducted by varying one parameter per simulation over a range of values. There is overlap between the model calibration step and sensitivity analysis in that sensitivity analysis is conducted both during calibration (the past) and can be conducted for predictions February 21, 2023, Reg CC Mtg., Page #248

(the future). If a parameter input is adjusted during calibration and that change in value does not affect the model calibration, then that parameter is not considered to be sensitive.

For the BIOCHLOR model, a number of parameters can affect the model including source concentrations, soil Foc and organic carbon partitioning coefficients (which together determine the retardation factor for adsorption/advection), seepage velocity, and the degradation constant(s).

The sensitivity analysis involved changing these parameters and comparing the resulting predicted plume length with the calibrated model results. A summary of sensitivity runs performed is discussed in the subsections which follow and the variation on model results for PCE concentrations are shown in Table 3-1.

Foc and Retardation Factor
There were no site-specific data available for Foc values, therefore the model default value (0.001) was used. The Foc parameter has a direct effect on the retardation factor.

High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 16 Rev 1: 318160-40240-WW-REP-0001
For the sensitivity analysis, the model-default value for Foc (0.001) was adjusted an order of magnitude larger (0.01) and smaller (0.0001) to assess how the predicted plume changed in length and concentration with changing retardation values.

Seepage Velocity
Seepage velocity was used as a calibration parameter. During the calibration step, it was noted that changing the seepage velocity while keeping other parameters constant could significantly change the plume length prediction. It is unlikely that the entire modeled area has a single seepage velocity (as assumed by BIOCHLOR), thus a sensitivity analysis on seepage velocity is warranted.

As determined during calibration, a seepage velocity of 156.4 ft/year provides a reasonable match for the field data. For the sensitivity analysis, the seepage velocity was increased and decreased by a factor of 10 to evaluate resulting changes in plume magnitude.

Degradation Constant (PCE to TCE)
The calibration step also indicated that the degradation constant is a sensitive parameter as small changes to it created relatively large changes in the predicted concentrations along the centerline of the plume.

As determined in calibration, degradation constants (lambda) of 0.07 (TCE), 0.693 (PCE), 13.86 (DCE), and

1.733 (VC) yr-1 provide a match between model results and the field data. These values were based on ranges of degradation constants provided in Wiedemeier et al. (1999) and adjusted to match field data.

For the sensitivity analysis, the degradation constants were decreased to zero (i.e., no biotransformation occurring) to evaluate resulting changes in plume magnitude.

4 Capture Zone Assessment
Assessing the capture zone of Lomita Well #5 (i.e., the Silverado Aquifer) is an important part of determining the well vulnerability as contamination present within the capture zone of a production well is likely to be drawn towards the well. Although Lomita Well #5 is screened within the Silverado Aquifer (i.e., deeper than the RWTA), historical reports suggest that the clay layer which separates the Gage Aquifer and underlying Silverado Aquifer may be absent in the Torrance area, and that the Gage (RWTA) and Silverado Aquifers merge (as noted in Section 2.3). In areas where the clay layer (i.e., the aquitard separating the RWTA and Silverado) is absent, the Silverado is vulnerable to potential cVOCs migrating downward from the RWTA.

A capture zone is generally defined as the areal extent of groundwater that is supplied to a pumping production well based on a time of travel criteria (e.g., 2, 5 or 10 years; Fitts 2013). The shape and extension of the capture zone is defined by the geometry and hydrogeologic properties of the pumped aquifer and associated boundary conditions (Feyen et. al 2001).

A semi-analytical model was used to estimate the capture zone dimensions for steady-state pumping of Lomita Well #5. The key assumptions for the capture zone analysis are as follows:
• the aquifer is homogeneous, isotropic, and infinite in horizontal extent • a uniform regional hydraulic gradient is present
• a constant well pumping rate
• uniform flow (i.e., steady-state conditions)
• the confining layer prevents leakage between the unconfined aquifer (the Gage Aquifer) and the underlying confined aquifer (the Silverado Aquifer); and • vertical gradients are negligible.

The saturated thickness of the Silverado Aquifer is estimated to be 245 ft thick based on regional water level measurements and estimated depth to the base of the aquifer (WRD 2022). For the Silverado Aquifer, a hydraulic gradient of 0.004 ft/ft was derived using regional water levels measured in September 2021 at WRD monitoring Wells Lomita 1 and PM-3 Madrid, located within the Project Area (WRD 2021b).

An aquifer test has not been performed on Lomita Well #5; thus, hydraulic conductivity and transmissivity values are not available for the well. Slug tests conducted on USGS monitoring wells within the West Coast Basin reported hydraulic conductivity values between 3 to 70 ft/day (USGS 2002 and 2003). Due to the uncertainty of hydraulic parameters, capture zone calculations were performed using a range of hydraulic conductivity values (from 25 to 75 ft/day) to provide a range of output parameters (i.e., stagnation point and capture zone width).

Using an average extraction rate of 426.5 gpm (based on the highest pumping rate at Lomita Well #5 from 2014 to 2018) and a bulk horizontal hydraulic conductivity of 25 to 75 ft/day, the modeled downgradient stagnation point ranges from 533 to 178 ft and the maximum width of the upgradient capture zone ranges from approximately 1675 to 560 ft, as shown in Figure 4-1.

For the scenario where pumping is increased to the City’s full adjudicated rate of 1,352 acre-feet per year, the maximum pumping rate would increase to 838 gpm. For this scenario, the modeled capture zone width would increase, with estimates ranging between to 1,097 ft to 3,292 ft, for hydraulic conductivity values of 75 ft/day and 25 ft/day, respectively, as shown on Figure 4-2.

5 Results and Recommendations
Results
Results of the BIOCHLOR steady-state (100 year) simulation are summarized on Figure 5-1 and Figure 5-2, which show concentrations of PCE and TCE, respectively, versus distance from the assumed source (in ft).

PCE and TCE are regulated contaminants with an established Maximum Contaminant Level (MCL) for drinking water at 0.005 milligrams per liter (mg/L). Results from the steady-state model show that with a continuous source of PCE over time, concentrations of PCE remain above the MCL beyond 5,000 ft from the assumed source area (Figure 5-1), while TCE concentrations decrease to below the MCL approximately 3,300 ft beyond the assumed source area (Figure 5-2). The assumed source area is approximately 1.25 miles (approximately 6,600 feet) from Lomita Well #5, although it not located directly along the centerline of the plume (as shown previously on Figure 3-2).

Figure 5-1 Modeling Results of PCE Concentrations During Steady-State (100 year) Simulation Figure 5-2 Modeling Results of TCE Concentrations During Steady-State (100 year) Simulation February 21, 2023, Reg CC Mtg., Page #254
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 21 Rev 1: 318160-40240-WW-REP-0001
A simulation run of 40 years (i.e., 1991 to 2031) predicts that the PCE concentration above the MCL (0.005 mg/L) may migrate from the original source to a total distance of approximately 4,500 ft within the next 10 to 20 years (Figure 5-3) and that TCE above the MCL may migrate as far as 3,300 ft (Figure 5-4).

Although Lomita Well #5 is not directly downgradient of the source (i.e., along the plume centerline), the capture zone of the production well may overlap with the predicted plume margins, most notably if the pumping rate at Lomita Well #5 is increased to the full adjudicated rate, hydraulic conductivity values of the Silverado Aquifer are higher than assumed, or the groundwater flow direction is more southerly than anticipated. Both scenarios assume no source control and/or remediation occurs at the SCPs.

Figure 5-3 Modeling Results of PCE Concentrations During Steady-State Simulation of 40 years Figure 5-4 Modeling Results of TCE Concentrations During Steady-State Simulation of 40 years Overall, based on the data available and assumptions summarized above, results of the BIOCHLOR model predict that there is a potential for unmitigated cVOCs to reach the capture zone of Lomita Well #5 at concentrations above the current MCL within the next 10 to 20 years. However, the potential travel times of cVOCs within the capture zone to Lomita Well #5 have not been estimated and are outside the scope of this report.

High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 22 Rev 1: 318160-40240-WW-REP-0001
Recent benzene impacts at Lomita Well #5 also indicate that the well may be susceptible to groundwater contamination. Although the source of benzene has not yet been identified, it is inferred that benzene impacting Lomita Well #5 traveled from a near surface source (i.e., an UST or surface spill), which would indicate that the Silverado Aquifer near Lomita Well #5 is also vulnerable to vertical downward migration of potential cVOC impacts. However, there is currently no indication that cVOCs have migrated vertically from the Gage Aquifer to the Silverado Aquifer at the SCPs since deep monitoring wells at the SCPs have reported non-detectable concentrations of cVOCs since their installation (BBL 2001 and GE&R 2021b).

Although the predicted migration of the cVOC plume within the Gage Aquifer reaches the capture zone of Lomita Well #5 over time, there is uncertainty with respect to the hydraulic connectivity between the Gage Aquifer and Silverado Aquifer within the Project Area. Notably, there is uncertainty as to whether the cVOCs would travel vertically through the aquitard underlying the Gage Aquifer and then into the Silverado Aquifer, and if so, what the estimated travel time(s) would be. Data from WRD’s Lomita Well #1 indicates that there is a downward vertical hydraulic gradient (i.e., between the Gage and Silverado Aquifers) near Lomita Well #5 (WRD 2021b); however, there are a number of data gaps that reduce the certainty of assessing the risk of contamination, including:
• There is limited information outside of the SCPs to determine local groundwater flow directions of the Gage Aquifer and Silverado Aquifer within the Project Area. Regionally, groundwater flow direction is influenced by the WCBBP (west of the Project Area) and by the Dominguez Barrier Wall (east of the Project Area); however, how these influences affect local groundwater flow are uncertain in the Project Area.
• There are a limited number of deep monitoring wells and geological cross-sections within the region which leads to uncertainty as to whether the regional aquitard is laterally extensive across the Project Area. If there are areas where the aquitard does not exist (i.e., areas where the Gage and Silverado Aquifers merge) or areas of higher hydraulic conductivity, there is potential for the cVOCs to preferentially migrate vertically into the Silverado Aquifer. • The limited number of deep monitoring wells (i.e., wells screened across the Silverado Aquifer) also means there is the potential that historical and/or future contaminant source(s) and/or pathways may not have been identified to date.
• The effects of pumping on the hydraulic gradient between the Gage Aquifer and Silverado Aquifer is currently unknown but may influence the lateral and vertical migration of cVOCs within the capture zone of Lomita Well #5.

Recommendations
Based on the data available, current CSM and evaluation results, the potential for cVOCs to migrate to within the capture zone of Lomita Well #5 exists, most notably if pumping rates at the production well increase, if there are areas where the aquitard between the RWTA and Silverado Aquifer does not exist, and/or if remediation of the source area does not occur.

To monitor for potential future impacts to the City’s only production well, the following recommendations are made:

February 21, 2023, Reg CC Mtg., Page #256
High-Level Evaluation of Potential Impacts from Chlorinated Solvents on Lomita Well #5 Advisian 23 Rev 1: 318160-40240-WW-REP-0001
• The CSM and evaluation should be updated as new data becomes available. It is recommended that the CSM be updated every two to three years as new data becomes available to confirm migration of the cVOCs (e.g., travel times or pathways) has not changed significantly. • A monitoring well network (i.e., sentry wells), installed along the edge of Lomita Well #5’s 5-year capture zone, is needed to confirm assumptions used herein, address existing data gaps within the current CSM, and protect the public water supply.
• The monitoring well network should consist of a minimum of one nested well which includes a piezometer in each target aquifer (e.g., the Gage Aquifer, Lynwood Aquifer, and Silverado Aquifer) to assess changes in water level elevations and water quality over time. The monitoring well(s) could also be used to evaluate hydrogeologic conditions near Lomita Well #5 (e.g., hydraulic gradients and hydraulic conductivity values).
• A suitable location for an additional production (water supply) well should be identified. A second production well would provide a contingency well in case of future adverse impacts to Lomita Well #5 and could also be used to supplement the City’s current water supply.

Upon request, CITY shall provide CONTRACTOR with a copy of the prevailing rates of per diem wages in effect at the commencement of this Agreement.

CONTRACTOR shall defend, indemnify and hold the CITY, its officials, officers, February 21, 2023, Reg CC Mtg., Page #267

Page 4 of 13 ends

employees, agents, and volunteers free and harmless from any claim or liability arising out of any failure or alleged failure to comply with the Prevailing Wage Laws.

If the services are being performed on a public works project of over $25,000 when the project is for construction, alteration, demolition, installation, or repair work, or a public works project of over $15,000 when the project is for maintenance work, in addition to the foregoing, then pursuant to Labor Code sections 1725.5 and 1771.1, CONTRACTOR and all subcontractors must be registered with the Department of Industrial Relations (“DIR”). CONTRACTOR shall maintain registration for the duration of the project and require the same of any subcontractors. This project may also be subject to compliance monitoring and enforcement by the DIR. It shall be CONTRACTOR’S sole responsibility to comply with all applicable registration and labor compliance requirements, including the submission of payroll records directly to the DIR. Any stop orders issued by the DIR against CONTRACTOR or any subcontractors that affect CONTRACTOR’S performance of services, including any delay, shall be CONTRACTOR’S sole responsibility. Any delay arising out of or resulting from such stop orders shall be considered CONTRACTOR caused delay and shall not be compensable by CITY.

CONTRACTOR shall defend, indemnify and hold CITY, its officials, officers, employees and agents free and harmless from any claim or liability arising out of stop orders issued by the DIR against CONTRACTOR or any subcontractor.

C. Labor Certification. By its signature hereunder, CONTRACTOR certifies that it is aware of the provisions of Section 3700 of the California Labor Code which require every employer to be insured against liability for Worker's Compensation or to undertake self-insurance in accordance with the provisions of that Code, and agrees to comply with such provisions before commencing the performance of the Services.

E. CONTRACTOR or subcontractors may not perform work on a public works project with a subcontractor who is ineligible to perform work on a public project pursuant to Labor Code section 1777.1 or 1777.7. Any contract on a public works project entered into between CONTRACTOR and a debarred subcontractor is void as a matter of law. A debarred subcontractor may not receive any public money for performing work as a subcontractor on a public works contract. Any public money that is paid or may have been paid to a debarred subcontractor by CONTRACTOR on the project shall be returned to CITY. CONTRACTOR shall be responsible for the payment of wages to workers of a debarred subcontractor who has been allowed to work on the Project.

CONTRACTOR shall be as fully responsible to CITY for the acts and omissions of its subcontractor and of persons either directly or indirectly employed by its subcontractor, as CONTRACTOR is for acts and omissions of persons directly employed by CONTRACTOR.

A. Except as otherwise provided, CITY may terminate this Agreement at any time with or without cause. Notice of termination shall be in writing.

B. CONTRACTOR may terminate this Agreement. Notice will be in writing at least 30 days before the effective termination date.

C. In the event of such termination, CONTRACTOR shall cease services as of the date of termination, all finished or unfinished documents, data, drawings, maps, and other materials prepared by CONTRACTOR shall, at CITY’s option, become CITY’s property, and CONTRACTOR will receive just and equitable compensation for any work satisfactorily completed up to the effective date of notice of termination.

D. Should the Agreement be terminated pursuant to this Section, CITY may procure on its own terms services similar to those terminated.

15. INDEMNIFICATION.

A. CONTRACTOR shall indemnify, defend with counsel approved by CITY, and hold harmless CITY, its officers, officials, employees and volunteers from and against all liability, loss, damage, expense, cost (including without limitation reasonable attorneys fees, expert fees and all other costs and fees of litigation) of every nature arising out of or in connection with CONTRACTOR's performance of work hereunder or its failure to comply with any of its obligations contained in this AGREEMENT, regardless of CITY’S passive negligence, but excepting such loss or damage which is caused by the sole active negligence or willful misconduct of CITY. Should CITY in its sole discretion find CONTRACTOR’S legal counsel unacceptable, then CONTRACTOR shall reimburse CITY its costs of defense, including without limitation reasonable attorneys fees, expert fees and all other costs and fees of litigation.

CONTRACTOR shall promptly pay any final judgment rendered against CITY (and its officers, officials, employees and volunteers) covered by this indemnity obligation. It is expressly understood and agreed that the foregoing provisions are intended to be as broad and inclusive as is permitted by the law of the State of California and will survive termination of this Agreement.

B. The requirements as to the types and limits of insurance coverage to be maintained by CONTRACTOR as required by Section 19, and any approval of said insurance by CITY, are not intended to and will not in any manner limit or February 21, 2023, Reg CC Mtg., Page #269

Page 6 of 13 ends

qualify the liabilities and obligations otherwise assumed by CONTRACTOR pursuant to this Agreement, including, without limitation, to the provisions concerning indemnification.

16. ASSIGNABILITY. This Agreement is for CONTRACTOR’s professional services.

CONTRACTOR’s attempts to assign the benefits or burdens of this Agreement without CITY’s written approval are prohibited and will be null and void.

17. INDEPENDENT CONTRACTOR. CITY and CONTRACTOR agree that CONTRACTOR will act as an independent contractor and will have control of all work and the manner in which is it performed. CONTRACTOR will be free to contract for similar service to be performed for other employers while under contract with CITY. CONTRACTOR is not an agent or employee of CITY and is not entitled to participate in any pension plan, insurance, bonus or similar benefits CITY provides for its employees. Any provision in this Agreement that may appear to give CITY the right to direct CONTRACTOR as to the details of doing the work or to exercise a measure of control over the work means that CONTRACTOR will follow the direction of the CITY as to end results of the work only.

18. AUDIT OF RECORDS.

A. CONTRACTOR agrees that CITY, or designee, has the right to review, obtain, and copy all records pertaining to the performance of this Agreement.

CONTRACTOR agrees to provide CITY, or designee, with any relevant information requested and will permit CITY, or designee, access to its premises, upon reasonable notice, during normal business hours for the purpose of interviewing employees and inspecting and copying such books, records, accounts, and other material that may be relevant to a matter under investigation for the purpose of determining compliance with this Agreement.

CONTRACTOR further agrees to maintain such records for a period of three (3) years following final payment under this Agreement.

B. CONTRACTOR will keep all books, records, accounts and documents pertaining to this Agreement separate from other activities unrelated to this Agreement.

19. CORRECTIVE MEASURES. CONTRACTOR will promptly implement any corrective measures required by CITY regarding the requirements and obligations of this Agreement. CONTRACTOR will be given a reasonable amount of time as determined by CITY to implement said corrective measures.

A. CONTRACTOR, at CONTRACTOR’s own cost and expense, shall procure and maintain, for the duration of the contract, the following insurance policies:

February 21, 2023, Reg CC Mtg., Page #270

Page 7 of 13 ends

1. Workers Compensation Insurance as required by law. CONTRACTOR shall require all subcontractors similarly to provide such compensation insurance for their respective employees. Any notice of cancellation or non-renewal of all Workers’ Compensation policies must be received by CITY at least thirty (30) days prior to such change. The insurer shall agree to waive all rights of subrogation against CITY, its officers, agents, employees, and volunteers for losses arising from work performed by CONTRACTOR for CITY.

2. General Liability Coverage. CONTRACTOR shall maintain commercial general liability insurance in an amount of not less than one million dollars ($1,000,000) per occurrence for bodily injury, personal injury, and property damage. If a commercial general liability insurance form or other form with a general aggregate limit is used, either the general aggregate limit shall apply separately to the work to be performed under this Agreement or the general aggregate limit shall be at least twice the required occurrence limit.

3. Automobile Liability Coverage. CONTRACTOR shall maintain automobile liability insurance covering bodily injury and property damage for all activities of CONTRACTOR arising out of or in connection with the work to be performed under this Agreement, including coverage for owned, hired, and non-owned vehicles, in an amount of not less than one million dollars ($1,000,000) combined single limit for each occurrence.

4. Professional Liability Coverage. CONTRACTOR shall maintain professional errors and omissions liability insurance for protection against claims alleging negligent acts, errors, or omissions which may arise from CONTRACTOR’S operations under this Agreement, whether such operations be by CONTRACTOR or by its employees, subcontractors, or subcontractors. The amount of this insurance shall not be less than one million dollars ($1,000,000) on a claims-made annual aggregate basis, or a combined single-limit-per-occurrence basis. When coverage is provided on a “claims made basis,” CONTRACTOR will continue to renew the insurance for a period of three (3) years after this Agreement expires or is terminated.

Such insurance will have the same coverage and limits as the policy that was in effect during the term of this Agreement, and will cover CONTRACTOR for all claims made by CITY arising out of any errors or omissions of CONTRACTOR, or its officers, employees or agents during the time this Agreement was in effect.

1. “The CITY, its elected or appointed officers, officials, employees, agents, February 21, 2023, Reg CC Mtg., Page #271

Page 8 of 13 ends

and volunteers are to be covered as additional insureds with respect to liability arising out of work performed by or on behalf of the CONTRACTOR, including materials, parts, or equipment furnished in connection with such work or operations.”

2. This policy shall be considered primary insurance as respects CITY, its elected or appointed officers, officials, employees, agents, and volunteers.

Any insurance maintained by CITY, including any self-insured retention CITY may have, shall be considered excess insurance only and shall not contribute with this policy.

3. This insurance shall act for each insured and additional insured as though a separate policy had been written for each, except with respect to the limits of liability of the insuring company.

4. The insurer waives all rights of subrogation against CITY, its elected or appointed officers, officials, employees, or agents.

5. Any failure to comply with reporting provisions of the policies shall not affect coverage provided to CITY, its elected or appointed officers, officials, employees, agents, or volunteers.

6. The insurance provided by this policy shall not be suspended, voided, canceled, or reduced in coverage or in limits except after thirty (30) days’ written notice has been received by CITY.

C. CONTRACTOR agrees to provide immediate notice to CITY of any claim or loss against Contractor arising out of the work performed under this agreement.

CITY assumes no obligation or liability by such notice, but has the right (but not the duty) to monitor the handling of any such claim or claims if they are likely to involve CITY.

D. Any deductibles or self-insured retentions must be declared to and approved by CITY. At CITY’s option, CONTRACTOR shall demonstrate financial capability for payment of such deductibles or self-insured retentions.

E. CONTRACTOR shall provide certificates of insurance with original endorsements to CITY as evidence of the insurance coverage required herein.

Certificates of such insurance shall be filed with CITY on or before commencement of performance of this Agreement. Current certification of insurance shall be kept on file with CITY at all times during the term of this Agreement.

F. Failure on the part of CONTRACTOR to procure or maintain required insurance shall constitute a material breach of contract under which CITY may terminate this Agreement pursuant to Section 13 above.

G. The commercial general and automobile liability policies required by this February 21, 2023, Reg CC Mtg., Page #272

Page 9 of 13 ends

Agreement shall allow CITY, as additional insured, to satisfy the self-insured retention (“SIR”) and/or deductible of the policy in lieu of the CONTRACTOR (as the named insured) should CONTRACTOR fail to pay the SIR or deductible requirements. The amount of the SIR or deductible shall be subject to the approval of the City Attorney and the Finance Director. CONTRACTOR understands and agrees that satisfaction of this requirement is an express condition precedent to the effectiveness of this Agreement. Failure by CONTRACTOR as primary insured to pay its SIR or deductible constitutes a material breach of this Agreement. Should CITY pay the SIR or deductible on CONTRACTOR’S behalf upon CONTRACTOR’S failure or refusal to do so in order to secure defense and indemnification as an additional insured under the policy, CITY may include such amounts as damages in any action against Contractor for breach of this Agreement in addition to any other damages incurred by CITY due to the breach.

21. USE OF OTHER CONTRACTORS. CONTRACTOR must obtain CITY’s prior written approval to use any Contractors while performing any portion of this Agreement. Such approval must include approval of the proposed Contractor and the terms of compensation.

22. FINAL PAYMENT ACCEPTANCE CONSTITUTES RELEASE. The acceptance by the CONTRACTOR of the final payment made under this Agreement shall operate as and be a release of CITY from all claims and liabilities for compensation to the CONTRACTOR for anything done, furnished or relating to the CONTRACTOR’S work or services. Acceptance of payment shall be any negotiation of CITY’S check or the failure to make a written extra compensation claim within ten (10) calendar days of the receipt of that check. However, approval or payment by CITY shall not constitute, nor be deemed, a release of the responsibility and liability of CONTRACTOR, its employees, sub-Contractors and agents for the accuracy and competency of the information provided and/or work performed; nor shall such approval or payment be deemed to be an assumption of such responsibility or liability by CITY for any defect or error in the work prepared by CONTRACTOR, its employees, sub-Contractors and agents.

23. CORRECTIONS. In addition to the above indemnification obligations, the CONTRACTOR shall correct, at its expense, all errors in the work which may be disclosed during CITY’S review of CONTRACTOR’S report or plans. Should the CONTRACTOR fail to make such correction in a reasonably timely manner, such correction shall be made by CITY, and the cost thereof shall be charged to CONTRACTOR. In addition to all other available remedies, CITY may deduct the cost of such correction from any retention amount held by CITY or may withhold payment otherwise owed CONTRACTOR under this Agreement up to the amount of the cost of correction.

24. NON-APPROPRIATION OF FUNDS. Payments to be made to CONTRACTOR by CITY for services preformed within the current fiscal year are within the current fiscal budget and within an available, unexhausted fund. In the event that CITY does not appropriate sufficient funds for payment of CONTRACTOR’S services February 21, 2023, Reg CC Mtg., Page #273

Page 10 of 13 ends

beyond the current fiscal year, the Agreement shall cover payment for CONTRACTOR’S only to the conclusion of the last fiscal year in which CITY appropriates sufficient funds and shall automatically terminate at the conclusion of such fiscal year.

SECTION 3: SCOPE OF WORK

SCOPE OF WORK
This Work Plan has been prepared to meet the City of Lomita’s (City) needs as efficiently as possible. This plan is based on the City’s Scope of Work in the Request for Proposal (RFP) and Stetson’s knowledge of the West Coast Basin and expertise in well siting, design, and construction management. Although the Work Plan is brief due to page limitations, all the tasks in the RFP are included in this proposal.

A timeline schedule (Table 4) depicting the sequence and duration of tasks and the Estimated ManHours Matrix (Table 5) required to complete the Work Plan are included. The associated fee proposal for this work plan is being provided in a separate, sealed envelope. Also listed in this Work Plan are optional tasks which may be considered by the City.

The City intends to conduct a feasibility study for a new groundwater production well. Currently, the City has groundwater rights of 1,352-acre feet (ac-ft) in the West Coast Basin. Due to the detection of benzene, the City’s only groundwater source well, Well No. 5, has remained offline since May 2019. Well No. 5 is anticipated to resume operation in early 2023. In calendar year 2018, Well No. 5 produced 561 acre-feet of groundwater. To form a basis of a long-term reliable water supply, the City is considering developing a new municipal water supply well in City limits or neighboring cities in the West Coast Basin.

The specific capacity (gpm/ft) of a well is the pumping rate (gpm) (Q) divided by the drawdown in feet(s). Specific capacity mapping for the area around the City digitized from the Water Replenish District’s (WRD) Technical Bulletin, Volume 2, 2005, Well No. 5, and one WRD nested monitoring well, Lomita #1, are shown in Figure 2. The specific capacity is a measure of the effectiveness of a well. Figure 2 shows that most of the area within the City has a specific capacity value from 100 to 200 gpm/ft. Attachment C of the RFP reported that the shallow groundwater flows east-southeast, and chlorinated solvents are primarily migrating laterally versus vertically.

We understand that in addition to high concentrations of iron and manganese, the City’s existing water supply well #5 is potentially impaired by chlorinated volatile organic compounds (cVOCs). It is of concern that a new well site is likely to be affected by Trichloroethene (TCE) and Tetrachloroethene (PCE) as well. Therefore, key water quality constituents which could affect treatment requirements are manganese, iron, TCE and tetrachloroethylene (PCE).

The purpose of the proposed study is to:
• Collect and review well yield, pumping level, static level, specific capacity, environmental and existing infrastructure data from the US geological Survey (USGS), WRD, State Water Board, and California Department of Water Resources.
• Characterize the subsurface geology both within the City limits and in neighboring cities in the West Coast Basin
• Analyze available groundwater data to help identify key aquifer parameters in this study area (i.e., static water levels, groundwater flow directions, transmissivity, and groundwater quality)
• Determine the hydrogeologic feasibility of developing one new groundwater supply well • Identify potential locations and evaluate land availability, permit requirement and connections to the existing collection system in a priority ranking order for the well locations February 21, 2023, Reg CC Mtg., Page #289

For the purpose of siting the new well in the West Coast Basin, we recognize that the team selected for the project should have a firm grasp of the key hydrogeologic issues for development of groundwater resources and also of the methods for resolving logistical or hydrogeologic issues related to well siting. Stetson has assembled a team because of their individual skills and experience, as well as their proven track record in working together on similar projects. This Stetson team can begin working promptly on the New Groundwater Well Feasibility Study.

A list of potential project issues that will impact the well site selection and eventual cost of construction of the new wells is shown on Table 2. This table also contains our team’s approach and similar projects where we have dealt with the issue.

Our knowledge of these key issues has been developed through our current and previous work efforts, the most important of which is the ongoing correlation of electric log signatures throughout the Central and West Coast Basins. This effort is the key to understanding the location, thickness, and continuity of the aquifers underlying the local groundwater basins. We understand that the aquifers underneath the Central Basin and West Coast Basins are the Recent Aquifer system, the Lakewood aquifer system, Upper and Lower San Pedro aquifer systems and the Pico Unit, among which the Lynwood and Silverado aquifers in the Upper San Pedro aquifer system are the most productive.

written and verbal communication throughout the project. Stetson will prepare meeting agendas and meeting minutes for City review. A total of 32 man-hours is estimated to complete Task 1.

TASK 2 DATA RESEARCH AND INVESTIGATION
Stetson has an in-depth working knowledge and comprehensive data on the hydrogeology of the West Coast Basin. One of Stetson’s proposed team members, Dr. Chaoying Jiao conducted two similar well site feasibility studies for other clients in the Central and West Coast Basins from 2010 to 2014. Stetson’s project manager Mr. Helsley was formerly the District Engineer and Assistant General Manager of WRD, where he was responsible for the development and implementation of programs to enhance groundwater recharge, improve groundwater basin management, and project groundwater quality. Mr. Helsley’s experience includes employment with the Los Angeles County Department of Public Works where he was responsible for studies to develop improvements to the County’s injection barriers to prevent seawater intrusion in the West Coast Basin, and studies of groundwater recharge optimization.

2.1 Data Collection and Review
Immediately following the Kick-off meeting, Stetson will collect and compile water well and/or test hole data, which consist of previous drilling locations and respective water well/test hole numbers; driller’s logs; casing records; borehole geophysical logs; water level monitoring data; efficiency test records; and water quality laboratory test results.

In preparation for this project, Stetson has already acquired the following information:
• Water level, production record, water quality and well construction of nearby production wells and monitoring wells from WRD’s website included in the RFP • Results of regional geologic field mapping of the area published by the California Department of Water Resources (DWR) and the United States Geological Survey (USGS) • Driller’s logs in the West Coast Basin, as available in our database; • Lithologic logs and electric logs for nearby wells owned by neighboring water companies and cities; and
• Data on pumping rates, water levels, and water quality for the wells in adjoining water districts and cities.

In addition to the data sources cited above, other potential sources of data may include the California Statewide Groundwater Elevation Monitoring (CASGEM), California State Water Resources Control Board (California Waterboards) Geotracker, Department of Toxic Substances Control (DTSC) Envirostor database, Division of Drinking Water (DDW), and State of California Department of Public Works’ Bulletin 45.

Stetson will review all available data and summarize findings in graphs and charts. In addition, information of land availability, existing water collection system and infrastructure will be gathered and compiled into GIS files.

Stetson anticipates completing this task within 9 weeks (Table 3) and the total man-hours needed is 36 (Table 4).

2.2 Review West Coast Basin Hydrogeology
A team meeting will be scheduled to perform site identification and review of hydrogeologic conditions and logistic constraints. In the siting and eventual construction of the new well, selection will depend on the: (1) hydrogeologic favorability of the site and (2) logistical favorability of the site.

February 21, 2023, Reg CC Mtg., Page #294
CITY OF LOMITA STETSON ENGINEERS INC.

Proposal to Provide Professional Engineering Services for 3-7 New Groundwater Well Feasibility Study
Submitted: January 17, 2023
In evaluating the hydrogeologic favorability, Stetson will use a four-tiered approach to identify areas of favorable hydrogeology for defining potential well sites:

1. Define the thickness and continuity of aquifer systems beneath the site.

2. Estimate the aquifer’s physical hydrogeologic properties, e.g., transmissivity and storability, from well logs and other data.

3. Assess the groundwater quality and respective treatment requirements for the site.

4. Determine groundwater flow directions, potential well interference, and production rates.

A total of 7 weeks is scheduled to complete this task (Table 3) and the total man-hours needed is 46 (Table 4).

2.3 Analysis of Potential Sites in the West Coast Basin After areas of favorable hydrogeology have been identified, at least three (3) sites lending to favorable logistics during construction will be considered. In this step, a few considerations are defined and evaluated:
• Land availability for potential well sites
• Size of the site and available area for treatment facilities, if needed • Temporary water supply availability for drilling of the pilot and final boreholes • Location of storm drains near the site for disposal of well development and testing water • Distance to potential connection to the collection and distribution systems • Cost of design, construction, and operation and maintenance of the proposed well sites; and • Set-back requirements per California Well Standards 74-81 and 74-90.

Stetson will conduct a thorough investigation of the required environmental assessment and permitting necessary for the success of the construction of a new well. Unattended, these requirements can present major challenges to the ultimate success of City’s project. Environmental concerns will be addressed and outlined in preparation for construction, for example, aesthetics and noise during construction.

If needed, treatment facilities may trigger additional permitting requirements. In addition, easement permits may be required. These permitting needs will be identified in this task, but it is assumed actual permitting will be completed in a future phase of the work.

Stetson anticipates completing this task within 9 weeks (Table 3) and the total man-hours needed is 56 (Table 4).

2.4 Field Reconnaissance
When the most favorable sites have been chosen from a hydrogeologic perspective, the Stetson team will coordinate with City staff to conduct a one-day field reconnaissance to investigate the size February 21, 2023, Reg CC Mtg., Page #295

1 TO: City Council
FROM: Ryan Smoot, City Manager
PREPARED BY: Brianna Rindge, Community & Economic Development Director MEETING DATE: February 21, 2023
SUBJECT: Discussion and Review of General Plan Update

RECOMMENDATION
No specific action requested, for discussion and review of the General Plan process.

BACKGROUND
Simply put, the purpose of a General Plan is to guide land use planning decisions. The document expresses the community’s development goals and embodies public policy relative to the distribution of future land uses, both public and private. Under State law, subdivisions, capital improvements, development agreements, and many other land use actions must be consistent with the adopted General Plan.

Lomita most recently updated its general plan in 1998 – 25 years ago – and since then, a lot has changed. While Lomita’s population has grown by 2.5%, development patterns and the range of housing types have transformed. Downtown Lomita has come to life.

The city is diversifying in both population and businesses alike. The COVID-19 pandemic has brought about new practices and uses that have yet to be incorporated into the city’s regulations. New projects have replaced former business types that have phased out.

New modes of transportation exist and previously considered modes have increased in popularity. Traffic along commercial corridors such as Pacific Coast Highway, Lomita Boulevard, and Western Avenue has grown, also increasing the number of visitors to the city. New land uses have come about but are not specifically provided for within Lomita’s existing code. Last, the Legislature has adopted numerous local requirements with which the City has yet to fully comply.

Recognizing the need for an update, City Council included a foundation of funding within its Strategic Plan over the past few years. With a new, permanent Community and Economic Development director, an approved Safety Element, a successfully certified Housing Element, and new State mandates, the time is right for Lomita to release a Item No. SCH 8b

CITY OF LOMITA

CITY COUNCIL REPORT
February 21, 2023, Reg CC Mtg., Page #320
2 Request for Proposal (RFP) for an update its General Plan and zoning ordinance.

ANALYSIS
Lomita’s certified Housing Element projects over 1,000 new housing units across the current planning period which runs through 2029 and the city must thoroughly evaluate the impacts of such growth on the community. A comprehensive update to the General Plan allows for consideration of current and future needs in areas such as land use, housing, transportation, public services, environmental quality, and economic viability.

The State established several deadlines by which every jurisdiction shall comply in addition to the requirement to rezone per the Housing Element by October 15, 2024 and the remaining certified Programs.

General Plan Element Update Status
Safety Updated & adopted December 2021
Housing Updated & certified October 2022
Land Use Update triggered by Housing Element update (rezone required by October 2024)
Circulation Update required by January 2025 per SB 932
Resource Management
(to be renamed Open
Space & Conservation)
Update required by January 2026 per SB 1425
Noise Update triggered by Land Use update
Economic Development Updated 1998; to be incorporated into other elements Implementation Updated 1998; to be incorporated into other elements The Land Use Element reflects the community’s vision, promoting thoughtful, equitable, and accessible distribution of different land uses, including residential, commercial, industrial, agricultural, and open space, and shall align with the other general plan elements. The Noise Element contains a set of goals, policies and implementation measures to limit noise exposure, particularly in areas with nearby housing, hospital, school or daycare center uses. The Circulation Element is a strategy addressing infrastructure needs for the circulation of people, goods, energy, water, sewage, storm drainage, and communications and must correlate directly with the Land Use Element.

The Open Space and Conservation Element identifies areas that provide value in an essentially undeveloped condition and creates a plan to preserve such areas. The open space portion reinforces conservation by guiding the comprehensive and long-range preservation of open space lands that are important to the conservation of the city’s natural resources (land, water, ecosystem services, and living resources).

Relation to Housing Element
California Government Code § 65585(i) grants the State Department of Housing and Community Development (HCD) the authority to review any action or failure to act by a local government that it determines is inconsistent with the adopted Housing Element and HCD has subsequently formed the Housing Accountability Unit. The requested scope of work achieves progress in 10 of the 31 adopted Housing Element Programs as required February 21, 2023, Reg CC Mtg., Page #321
3 by HCD as follows.

Program Description
28 Work with developers & community to explore opportunities to rezone areas ideal with density minimums for increased housing capacity through an update to the General Plan
14 Rezone per certified Housing Element due October 15, 2024 11 Develop design objective standards to help facilitate quality design paired with the increase in density as part of Program 14
30 Consider an inclusionary ordinance to pair with the rezoning of sites based on an economic feasibility analysis
7 Improve development regulations intended to incentivize affordable and mixed-income housing development through regulatory inducements such as incentive zoning paired with objective development standards 29 Amend zoning code to streamline, update, and simplify regulations related to housing, where possible
29 Update regulations in response to State legislative changes 12 Increase permitted density along Lomita Blvd.
12 Provide additional lot consolidation incentives to qualifying sites identified in the Sites Inventory Form

4 Project Process
The focus of the Update is to respond to changes in the community and in circumstances that affect the future direction of Lomita. The updates will be based upon the results of a comprehensive visioning process and public engagement program to ensure that all facets of the community participate and are fully represented in shaping Lomita’s future.

The entire process is expected to take approximately 2-3 years.

The City intends to form a General Plan Advisory Committee (GPAC), appointed by City Council and formed with the assistance of the consultant, and a Technical Advisory Committee (TAC) to be comprised of technical experts from City departments and partner agencies to provide feedback and ensure plan concepts are achievable. The consultant will release a community survey, maintain a webpage dedicated to the project, and ensure information is included in the City’s newsletter. The City expects to brand the Update with one simple phrase and logo.

Next, the consultant will produce a “Draft Existing Conditions Background Report” containing a summary of findings, data, assumptions, and a draft outline of the preliminary General Plan and prepare a Strengths, Weaknesses, Opportunities, and Threats (S.W.O.T.) Analysis of the existing General Plan and zoning ordinance. The Consultant will include GPAC and TAC input to create a “Final Background Report” which will be presented to Planning Commission and City Council.

The GPAC and TAC will review consultant’s evaluation of growth alternatives and identified policy options. Planning Commission and City Council will provide direction regarding the “Preferred Alternative”. The consultant will draft implementation strategies to include feasible actions the City will undertake to implement each of the goals, policies, and objectives. The GPAC and TAC move through a series of reviews along with community meetings. City Council and Planning Commission will hold public hearings on the Draft Update and, subsequently, the Final General Plan Update. The consultant will assist with zoning code updates as necessitated by the final document.

General Plan Advisory Committee
The ad-hoc GPAC is intended to represent a cross-section of the Lomita community.

Generally, a GPAC’s role is to provide input, feedback, and recommendations to the selected consultant, City staff, the Planning Commission, and ultimately to the City Council regarding key components and elements of the General Plan throughout its development. The GPAC is a discussion body designed to bring the many facets of the community to the table to help shape the vision for the City’s guiding documents. All GPAC meetings will be open to the public. In order to ensure the GPAC is representative of the community at large, staff encourages City Council to consider including individuals from the following non-exhaustive list of groups on the GPAC. • Parks and Recreation Commission
• Public Safety and Traffic Commission
• Lomita Chamber of Commerce/businesses
• Long-time residents
February 21, 2023, Reg CC Mtg., Page #323
5 • Newer residents
• Multiple generations
• Real estate industry
• Development community
• School district
• Fire and/or Police Department
CEQA Compliance
The chosen consultant will also prepare an Administrative Draft, Draft, and Final Environmental Impact Report (EIR), conduct all public reviews in accordance with the California Environmental Quality Act (CEQA) to create thorough and defensible CEQA documentation, and file all required notices. The City is interested in exploring the possibility of a General Plan EIR that will assist in streamlining and exempting future projects from CEQA with the idea that the General Plan EIR can be used for such exemptions when projects are consistent with the General Plan.

OPTIONS

1. No action; staff will release RFP

2. Discuss, and suggest amendments

FISCAL IMPACT
The RFP requests budget details within the proposals, but based on other cities’ experience, the cost can be expected to exceed $1 million for the General Plan Update and related CEQA documentation. If the consultant opts for a comprehensive zoning code update to include rezoning for West Lomita Blvd., this can be expected to cost an additional $200,000-$300,000. While patchwork zoning code updates may be less costly, it may also present conflicts that a wholistic review could avoid. The project is expected to occur over a 2- to 3-year period and utilize funding from the General Plan Update Fund of the City’s Biennial Budget. This Fund is projected at $600,000 by June 30, 2023, with additional funding planned for coming fiscal years. In addition, staff is actively seeking further funding opportunities through various state and federal grants and programs.

II. GENERAL INFORMATION
The city of Lomita is known as a friendly, small-town community located at the base of the Palos Verdes Peninsula in Los Angeles County. Lomita is 1.97 square miles (total area is 1,261 acres) with a population of approximately 21,000. The city is located 26 miles south of downtown Los Angeles and bounded by the Torrance to the north and west, Los Angeles to the east, Rolling Hills Estates to the southwest, and Rancho Palos Verdes and unincorporated Los Angeles County area to the south.

Lomita “began” as a residential tract (Lomita Subdivision) in the early 1900s. In 1907, the Lomita Subdivision covered seven square miles. In the 1940s and 1950s, portions of the Lomita Subdivision were annexed by adjacent cities. By 1964, only 1.97 square miles of the Lomita Subdivision remained when the City of Lomita finally incorporated on June 30, 1964. Lomita is a contract city with a Council-Manager form of government. The city council is elected at large to four-year terms. The mayor is selected by the city council for a one-year term. Lomita is considering transitioning to city council districts, with a decision expected in May 2023. Following the district formation process, the city would be divided into five separate districts in 2024.

In 1990, Lomita seceded from the Los Angeles County water district and assumed complete control and operation of a new water district serving the community. The City serves water to approximately 4,300 connections. Of these, the vast majority are residential connections (94%), with the majority of residential connections being single-family residential (3,712 connections).

The city is almost entirely built-out. Existing development within the city is characterized by residential neighborhoods at varying densities, with commercial uses concentrated along Pacific Coast Highway, Lomita Boulevard, Crenshaw Boulevard, Narbonne Avenue, and Western Avenue. Much of the city is comprised of single-family residential homes with many large lots providing in-fill housing opportunities.

Narbonne Avenue includes a combination of residential, commercial, and mixed-use of which the northern section is a quaint downtown and civic center area. The commercial corridors are underutilized and offer potential locations for new commercial, mixed-use, and high-density residential in accordance with the goals and objectives of the recently updated Housing Element. With its proximity to employment centers, coupled with its central location and excellent neighborhoods, Lomita is poised to leverage its location for continued housing, job creation, and economic growth that can improve the quality of life for residents. A key issue in planning for and facilitating the level of growth called for in the City’s Housing Element and upcoming General Plan update is utilization of land use, design, and development standards that strategically protect the low-density neighborhoods while supporting more intense development along the commercial corridors.

III. BACKGROUND
General Plan
Lomita’s General Plan was last comprehensively updated and adopted in 1998 with various amendments since. Of note, in 2005 and 2014, a General Plan Advisory Committee (GPAC) provided recommendations related to economic development, downtown revitalization, and circulation improvements. The current General Plan is comprised of 8 elements.

Circulation Update required by January 2025 per SB 932
Resource Management
(Open Space & Conservation)
Update required by January 2026 per SB 1425
Noise Update triggered by Land Use update
Economic Development Updated 1998; to be incorporated into other elements Implementation Updated 1998; to be incorporated into other elements This General Plan update is envisioned as a major update of the Land Use, Circulation, Open Space, and Noise elements, although minor revisions to the Housing Element and Safety Element may be necessary to provide consistency with the other elements. The Economic Development and Implementation elements are anticipated for incorporation into the other elements to ensure these factors are considered in all aspects of future planning and development. The Consultant is strongly encouraged to recommend an approach or vision for this project that will result in an innovative, user-friendly General Plan document that promotes thoughtful consideration of the future needs of the community and allows adequate flexibility for the changing needs of the Lomita’s residents.

Zoning Code
The City’s current zoning code is decades old and has been modified through various amendments to keep up with changes and new State requirements. The City is considering a complete overhaul of its current Zoning Ordinance and Map to be consistent with the updated General Plan. This would involve a repeal and replacement of the existing code. If not recommended, the City expects draft ordinances in accordance with the final adopted elements. The state of the current zoning code is as follows. • The code includes antiquated use tables, use classifications, and land use definitions. • It contains standards that are outdated, difficult to administer, and difficult to find. • It is not user-friendly and lacks graphics to improve readability. • The code does not reflect recent changes resulting from legal decisions and changes to state laws (i.e. SB 35, Telecommunications, WELO, etc.)
• The code lacks the ability to address modern development trends and patterns in the city's corridors, mixed-use and overlay areas.

Progress on Housing Element Programs
While the City does not seek further assistance on the recently adopted Housing Element, the Update will include progress on the following Housing Element programs. • Program 3 – analysis of mobile home park regulations; • Program 7 – affordable and mixed-income housing incentives paired with objective development standards;
• Program 11 – objective design standards to facilitate increase in density; • Program 12 – allow standalone residential in Mixed-Use Overlay; additional lot consolidation incentives; increase permitted density along Lomita Blvd.; February 21, 2023, Reg CC Mtg., Page #329

Page 5 of 12 ends

• Program 13 – permit large care residential facilities in commercial and mixed-use zones; • Program 14 – rezone due October 15, 2024;
• Program 27 – reduce multifamily parking requirements; reduce religious institution parking requirements in exchange for housing development consistent with AB 1851; • Program 28 – coordinate with developers to identify areas idea for density minimum implementation;
• Program 29 – update regulations in response to legislative amendments; streamline and simplify housing regulation; and
• Program 30 – consider an inclusionary ordinance to pair with the rezoning of sites based on an economic feasibility analysis.

In addition to land use concepts, the Consultants and staff will identify policy option topics to address key programmatic issues and opportunities. The Consultants and staff will review existing land use designations and develop a set of updated land use designations on which to base the land use alternative concepts. The land use designations will include allowed uses and standards of population density and building intensity as well as guidelines for urban form. The designations will be illustrated with graphics and images to show the intended development outcome. The Consultants will provide technical analysis to estimate a balanced land supply for the different components of market demand through the planning horizon year.
b. Evaluate Growth Alternatives and Identify Policy Options - Using the Alternatives Concepts, the Consultant and staff will develop population and employment projections based on buildout of each alternative. The Consultant will evaluate the land use alternatives in terms of impacts on an identified set of topics, such as existing/programmed public facilities or networks, the natural environment, the economy, greenhouse gas emission reduction, and City finances. The Consultant will address the fiscal implications of each alternative in five-year increments within the 20-year planning horizon. The Consultants and staff will develop policy options to address identified key assets, issues, and opportunities.
c. The Consultant(s) and Planning staff will facilitate TAC and GPAC review of the draft alternatives report.
d. Based on direction from the Planning Commission and the City Council, the Consultants and staff will prepare a Preferred Alternative land use diagram and description, as well as a set of preferred policy options to address identified assets, issues, and opportunities.
