Narrative:

Optional Submittal Table O-1B: Recommended Energy Reporting - SINGLE DELIVERY PRODUCT - TOTAL UTILITY APPROACH The total energy input in the table above includes energy from potable water distribution (from Fairfield's two treatment plants - NBR and Waterman). It includes treatment costs at pump stations that cannot be separated. The energy totals correspond to electricity supplied by PG&E, as well as solar energy generated at the NBR Treatment Plant.

The total volume of water entering the distribution system is based on the data in the district's CY2024 Water Loss Audits - Volume of Water Supplied, which includes total authorized consumption as well as water losses.

Only for Water Delivery Products Under the Urban Water Supplier's Operational Control
Sum of All Water Management
Processes Non-Consequential Hydropower
DWR NOTES:

Total Utility:The volume of water entered in the “Total Utility” column should equal the volume of water entering the distribution system (excluding recycled water); in most cases, this is the total volume calculated in UWMP Table 4-1: 2025 Actual Total Uses for Potable and Non-Potable Water. Note if recycled water is included in your Submittal Table 4-1, you must exclude it from your volume in this table.

NOTES:

All of Fairfield's supplies come from local water sources. Fairfield has accounted only for the energy used in the facilities they operate for treatment, and delivery of potable water.

AGENDA REPORT
DATE: June 16, 2026

TO: Acting Mayor and Council

FROM: David Gassaway, City Manager

SUBJECT: Resolution 2026-126 PW Amendment No. 1 to West Yost PSA NBR Expansion

Authorizing the City Manager to Execute Amendment No. 1 to the Professional Services Agreement with West Yost Associates for the North Bay Regional Water Treatment Plant Expansion Program and Authorizing an Update to the Fiscal Year 2025-2026 Budget

Funding Source: $304,100; North Bay Regional Fund

Contact: Michael J. Hether, (707) 428-7493

RECOMMENDED ACTION
Adopt resolution.

STATEMENT OF ISSUE
The North Bay Regional Water Treatment Plant (NBR WTP) is joi ntly operated by the Cities of Vacaville and Fairfield through a Joint Powers Agreement (JPA) executed in 1987 . Asboth cities are experiencing growth, there is a need to expand the facilities to accommodate future demand.

The proposed amendment to the Professional Services Agreement (PSA) with West Yost Associates adjusts the original scope and fee to support additional services, including capacity analysis, pipeline alignment, and environmental review.

DISCUSSION
On December 17, 2024, the City Council adopted Resolution No. 2024 -293, awarding the PSA to West Yost Associates for the North Bay Regional Water Treatment Plant Expansion Program (Project). The initial scope of services included facilities planning and analysis to define the NBR expansion, with a design-build project delivery approach.

As the Project advanced, additional scope and analyses not included in the original proposal were identified. West Yost provided a proposal for budget augmentation, outlining the minimal scope and cost adjustments necessary to complete the facilities planning process. Staff recommend approval of Amendment No. 1 to increase the Project’s authorized budget. The increased costs

Page 457 of 1351 ends

are attributable to an expanded scope of environmental studies and engineering planning analyses. Approval of this amendment will increase the PSA maximum authorization by $304,100 for a total not-to-exceed amount of $2,297,200.

FINANCIAL IMPACT
The JPA specifies that the administering party shall reimburse all direct and indirect costs incurred out of the J EPA fund. Both parties wish to pursue the NBRWTP expansion in additional design services and consequently will split all costs to complete this work.

The NBR Fund (Fund 465) will utilize previously collected reserves and will split the cost as follows:

City of Fairfield contribution: $139,709.50
City of Vacaville contribution: $164,390.50

The additional PSA costs for West Yost Associates were not included in the FY 2025-2026 Capital Improvement budget for the NBR Water Treatment Plant Expansion (CPW040114). A budget adjustment of $304,100 to include the additional costs and increase appropriations to the design costs is required. The project budget adjustment will be funded with fund balance from the North Bay Regional Fund (Fund 465).

PUBLIC CONTACT/ADVISORY BODY RECOMMENDATION
N/A

ALTERNATIVE ACTION
The council may choose not to authorize the city manager to execute the amendment. However, this would be inconsistent with the authority vested in the J oint Powers Policy Committee through the JEPA.

SUBJECT: Proposal for Budget Augmentation for Fairfield-Vacaville Water Works (NBRWTP Expansion) Program Management Services through Fall 2026

Dear Mr. Vong:

The purpose of this letter proposal is to request an amendment to West Yost’s existing contract for the North Bay Regional Water Treatment Plant (NBRWTP) Expansion Program (Program) to provide additional not-to-exceed funding consistent with the Budget Review and Cost Projection spreadsheet (v7.1, June 2026) as shown in Attachment 1. This amendment would extend/augment budget authority for continued program management services beyond the current authorization of June 30, 2026, and for initiating selected early activities needed to maintain the schedule. The requested amendment is $304,088 to accommodate anticipated services through Fall of 2026.

SCOPE OF SERVICES
The following tasks comprise the proposed additional scope for program management services. The program has been named the Fairfield-Vacaville Water Works (FVWW), which includes an expansion and rehabilitation of the NBRWTP and related water system improvements. The tasks align with the updated FVWW Program Schedule (v6.4.1, May 2026) and are further described below.

Task 1. Continued Program Management and Project Controls through September 2026
West Yost will continue to provide overall program management and coordination services to the Cities of Fairfield and Vacaville, including master program budget/cost tracking, master schedule tracking, executive leadership meetings, technical leadership team meetings, project controls/administration, and QA/QC review of West Yost deliverables. Work elements correspond generally to the following tasks and associated direct-cost allowances.
 Task 1.1: Program Management Plan
 Task 1.2: Master Program Budget
 Task 1.3: Master Program Schedule
 Task 1.4: Technical Leadership Team Meetings include Executive Team Meetings  Task 1.5: Project Controls and Administration

N-C-268 FAIRFIELD-40-24-26 NBR WTP EXPANSION-PM-PROPOSALS

 Task 1.6: QC of West Yost Documents
The original scope of work through June 2026 will be completed under budget. The remaining funds of $200,096 will support continuation of Task 1 services, but only to the extent the total authorized budget is sufficient.

Remaining budget is expected to be sufficient at least through September 2026.

Task 1 Assumptions
 City staff will continue to provide timely direction and decision-making through routine program meetings.  Existing program controls (SharePoint/document management, action/decision logs, and invoicing formats) will continue to be used unless revised by mutual agreement.  The level of effort will be limited to what can be accommodated within the overall authorized budget.

Task 1 Deliverables
 Updated cost tracking summaries (periodic).
 Updated master program schedule (periodic).
 Meeting agendas/minutes and action item tracking.

Task 2 – Joint Exercise of Powers Agreement and Memorandum of Understanding (MOU) – reduction in cost through December 2026 These two subjects were originally Tasks 1 and 2 in the contract. See Attachment 2 – Scope of Services for reference.

The Joint Exercise of Powers Agreement (JEPA) defining sharing of NBRWTP capacity and costs has served the two Cities well. However, with the undertaking of a major NBRWTP expansion project, the existing JEPA needed to be evaluated.

To date, West Yost has met with relevant Fairfield and Vacaville staff and legal counsel to discuss the existing JEPA. The Cities have determined that the JEPA could stand as is, supplemented by a new Memorandum of Understanding (MOU). The MOU is being developed by City staff and counsel from both Cities to address the FVWW program, ongoing operations and maintenance needs, and the cost sharing around both.

The legal teams are developing an MOU as of the date of this letter proposal. West Yost will continue to provide technical input as the MOU is developed. Just over half of the remaining funds, approximately $57,600, will be reallocated to other tasks and the remaining Task 2 budget will be retained to participate through completion of the MOU.

Task 3 – Data Collection and Additional Studies - reduction in cost The primary objective of this task was to provide the additional data necessary to ensure that the future design of NBRWTP improvements adequately balances the need for capacity, treated water quality, operational flexibility, and cost-effectiveness. Task 3 includes the following subtask:
 Task 3.1: Existing Information Review Workshop (completed)  Task 3.2: Sampling and Data Collection Plan (completed)  Task 3.3: Data Collection and Analysis (in progress)
 Task 3.4: Challenge Testing (completed)
 Task 3.5: Distributed Energy Resources Evaluation (in progress)

N-C-268 FAIRFIELD-40-24-26 NBR WTP EXPANSION-PM-PROPOSALS

 Task 3.6: Defining Electrical, Instrumentation and Controls Requirements (in progress) The majority of this task will be completed by the end of June 2026. The current Task 3 budget will be reduced by approximately $21,600, which can be reallocated to other tasks.

Task 3 Assumptions
 Electrical, Instrumentation and Controls Requirements to be included in the Project Technical Requirements

Remaining Task 3 Deliverables
 Project Data (organized water quality and performance data, digitized archives)  Distributed Energy Resources TM
Task 4 – Vacaville Capacity Strategy – scope and budget augmentation Vacaville was faced with important decisions regarding the buildout of its water supply portfolio and needed to more clearly define its future surface water and groundwater supply mix. Of particular importance, the continued use of existing facilities needed to be defined, including its Diatomaceous Earth Water Treatment Plant (DEWTP) and several of its existing water supply wells, which are aging and experiencing water quality issues due to contaminants of concern (e.g, Cr6+ and PFAS). These issues directly impact the allocation of treatment capacity at the NBRWTP needed for Vacaville and cost allocations between the two Cities. Accordingly, West Yost has prepared an evaluation and technical memorandum (TM) documenting Vacaville’s plan for using NBRWTP capacity. Key subtasks performed under Task 4 included:
 Task 4.1. Refinement of Demand Projections
 Task 4.2. Evaluation of Surface Water and Groundwater Supply Options  Task 4.3. Vacaville Capacity Strategy TM
Task 4 will be completed by finalizing the Technical Memo by the end of June 2026, or shortly thereafter, barring additional scope changes. The scope and budget is increased to include performing and documenting additional analyses of future distribution system impacts and improvements, and consideration of various well production scenarios. Additional funding is required to cover the work. The requested amendment amount is $19,297 and will only accommodate minor changes.

Task 4 Deliverable
 Updated and finalized TM
Task 5: Facilities Planning – reduction in cost
Under this task, facilities planning and workshops with operations staff were performed to develop a Project Technical Requirements document (PTR) providing the basis for the later detailed design of NBRWTP improvements. The facilities planning defined and evaluated a potential capacity phasing for meeting near- and long-term capacity needs and includes a planning level cost estimate. The PTR will incorporate the findings and conclusions of the May 24, 2024 technical memorandum (TM) titled “NBRWTP Condition Assessment, Performance Evaluation, and Expansion Analysis” (May 2024 NBRWTP TM). The key subtasks performed under Task 5 include:
 Task 5.1. Raw and Treated Water Quality Characterization

 Task 5.2. Existing Facilities Description
 Task 5.3-5.5: Project Technical Requirements Development  Task 5.6. Project Implementation Plan
 Task 5.7. Cost Estimate
 Task 5.8. Project Technical Requirements Document
Task 5 is expected to be completed by the end of June 2026, producing Project Technical Requirements in lieu of a report.

Task 5 Assumptions
 The governing technical requirements defining the needed Fairfield infrastructure (e.g., Cement Hill reservoir) will be developed largely by the City or under separate contract.  Cost estimates for added Fairfield infrastructure will rely on cost information provided by the City.  The Implementation Plan will be a brief, general description of schedule, project delivery method(s) and management plan to be incorporated in the Business Case Report (Task 8) and/or the Program Management Plan (Task 1).

Remaining Task 5 Deliverables
 Project Technical Requirements to be referenced in the progressive design-build contract.  Update to the cost estimate and cost allocation incorporating the ongoing cost sharing evaluation.

Task 6. Outside Funding – scope and budget augmentation Task 6 includes substantial added scope, including preparation of multiple funding applications. The minimum amendment would cover requested work performed to date, plus a $10,000 allowance for ongoing coordination. Assistance with any further loan application materials is not included in the budget, so a further budget amendment would be needed to allow for preparation of an Engineering Report to support an SRF loan application.

Subtasks under this effort included:
 Task 6.1: Funding Research (future work not budgeted)  Task 6.2: Meetings with Funding Agencies (future work not budgeted)  Task 6.3: Funding Strategy TM (completed)
 Task 6.4: Ongoing Opportunity Monitoring (future work not budgeted)  Task 6.5: Emerging Contaminants Grant Application – Vacaville (future work not budgeted)  Task 6.6: SRF Loan Application – Vacaville (future work not budgeted)  Task 6.7: SRF Loan Application – Fairfield (future work not budgeted)  Task 6.8: I-Bank Loan Application – Vacaville (future work not budgeted)  Task 6.9: I-Bank Loan Application – Fairfield (future work not budgeted)  Task 6.10: Congressionally Directed Funding Applications – Vacaville (future work not budgeted)
The requested amendment amount is $141,754.

Task 6 Assumptions
 City staff will conduct all ongoing coordination with funding agency(s).  No further progress on loan application documents will be needed unless and until the budget and scope are further amended.

Task 6 Deliverables
 None.

Task 7. Project Delivery Method Evaluation
A variety of project delivery methods are available for the NBRWTP expansion and related offsite projects, including traditional design-bid-build as well as collaborative project delivery methods such as progressive design-build. Key subtasks include:
 Task 7.1. Consultations with Staff and Legal Counsels of Both Cities  Task 7.2. Project Delivery Methods TM
 Task 7.3. Informational and Strategic Meetings/Workshops/Presentations West Yost has presented information and worked with the Cities to select progressive design build (PDB) for delivery of at least the NBRWTP improvements. The PDB contract will likely be used for the offsite improvements as well, unless a separate delivery method is more advantageous. Information was documented in a TM for presentation to both City Councils with a recommended approach based on the staff discussions.

This TM will now be on the same schedule to finalize as Task 8, the Business Case Documentation.

Task 7 will now include as-needed meetings or study sessions with staff and/or City Councils, as can be performed within the available budget. These may include strategic discussions to determine how various project elements might be phased within a single or multiple contracts.

Task 7 Assumptions
 One minor update to the draft memorandum may occur within the revised budget.  Preparation and participation in strategic meetings, workshops, or presentations will be provided within the limitation of available budget, according to project needs.

Task 7 Deliverables
 Final project delivery recommendations TM
Task 8: Business Case Documentation – scope augmentation The schedule for this task has shifted as the program has evolved. The current schedule for completion is early fall of 2026.
 Task 8.1. Business Case Report
 Task 8.2. City Council Presentations/Hearings

N-C-268 FAIRFIELD-40-24-26 NBR WTP EXPANSION-PM-PROPOSALS

Task 8 is currently projected through completion with no substantive change from the original budget; however, incorporating work by Bartle Wells was not originally anticipated. Completion of an initial draft is anticipated before the end of June 2026, with a finalized document by the end of 2026, allowing time for Council communications and incorporation of the financing plan, assuming it will be ready by then.

The original budget for Task 8 is adequate for the remaining work as currently projected.

Task 8 Assumptions
 Two City Council meetings/hearings (one for each City)  Bartle Wells is preparing a financing plan, the findings of which may be summarized in the Business Case Report if they are timely and easily incorporated.  Planning level costs with ample contingencies will be presented  The budget and scope for this task will be reviewed and updated (if necessary) as the project progresses

Task 8 Deliverables
 Draft and final Business Case Report
 Presentation materials for City Council meetings/hearings if needed.

Task 9: As-Needed Services – budget augmentation
Task 9 funds are for services not anticipated at the time of budgeting. After the initial budget was fully reallocated, $6,548 was invoiced under this task in July 2025 and is included in the requested amendment.

The charges were associated with early Outside Funding research related to a potential HMGP grant application, plus a small amount (4 hours) of internal management. The time was invoiced under Task 9 rather than Task 6 (or 1).

Task 10: Develop PDB Procurement Documents – scope and budget augmentation
This task includes creating the Request for Proposal (RFP) and assisting with preparation of a draft contract for progressive design build (PDB) services. This work was not included in the original scope.

West Yost has begun to develop a draft RFP, and has assisted in determining that a contract template from the Design Build Institute of America will be provided to legal counsel for consideration. The remaining budget less a small allowance for close out activities will be reallocated, such that no further progress on the draft RFP or PDB contract will be made absent a subsequent budget and scope amendment.

Task 10 Assumptions
 No further work on an RFP or PDB contract is needed at this time.  West Yost does not provide legal advice.

Task 10 Deliverables
 None.

Task 91: Environmental Review – scope and budget augmentation Task 91 was not included in the original scope and budget but was added to facilitate timely environmental review with the City’s concurrence that a budget amendment would be necessary. This task includes work

June 1, 2026

Page 7 ends

N-C-268 FAIRFIELD-40-24-26 NBR WTP EXPANSION-PM-PROPOSALS

by LSA (as a subconsultant to West Yost) conducting field work, research and preparation of a CEQA document plus additional information to facilitate required federal consultations for SRF funding, and coordination and work by the project team to prepare mapping and documentation. Some funds in the original budget were reallocated to this task from Task 9 and Task 1. The minimum amendment in the amount of $297,300, includes all anticipated work through the end of 2026 for completion of the CEQA document. The amendment does not include funding for the environmental permitting assistance.

Please refer to separate scope of work documents defining LSA’s services, provided in Attachment 3.

Task 92: Pipeline Alignment Study – scope and budget augmentation This task includes a study to evaluate different pipeline alignment options for a new transmission main from the NBRWTP to the City of Vacaville. The original scope for this is provided in Attachment 4. The scope was modified to omit profile drawings and add analyses including mapping existing utilities in more detailed plan view at points of connection, evaluating constraints at the Putah South Canal crossing, and adding the Peabody Road alignment. Upon completion of a draft document, it was requested that an additional alignment option be added to the analysis.

Task 92 was funded by moving budget from Tasks 1 and 9. The scope was not included in the original budget. A revised memo with an added alignment (Peabody Rd) will be completed before June 30, 2026, requiring a 5% increase in the previously allocated task budget (approximately $5,400).

PROJECT BUDGET
West Yost’s proposed additional budget for the tasks described above is summarized in the column labeled “Amendment Amount” in Attachment 1. Work will be performed in accordance with the terms of the Professional Services Agreement between the City of Fairfield and West Yost dated December 18, 2024, as amended. The requested budget augmentation is $304,088, resulting in a revised total not-to-exceed amount of $2,297,188. The anticipated allocation to the tasks described above is shown in Attachment 1 and is subject to reallocation in accordance with program needs.

SCHEDULE
West Yost will continue working with the Cities to maintain the master program schedule and adjust task sequencing as needed. This amendment includes services at least through September 2026. We understand the contract duration will be extended to December 31, 2026 or later, such that services could continue if needed, to the extent the budget allows.

Thank you for the opportunity to continue supporting the Cities of Fairfield and Vacaville on this important Program. We look forward to working with your team to maintain momentum toward procurement and project delivery. Please contact us if you have any questions or would like to discuss this amendment request.

Sincerely,

TASK 3. DATA COLLECTION AND ADDITIONAL STUDIES
To support updated, detailed analyses of the performance of existing facilities and the need for additional facilities and/or operational changes, additional data collection and investigations are needed. The primary objective of this task is to provide the additional data necessary to ensure that the design of future NBRWTP improvements adequately balances the need for capacity, treated water quality, operational flexibility, and cost-effectiveness. The key subtasks to be performed under Task 3 include:
• Task 3.1. Existing Information Review Workshop
• Task 3.2. Sampling and Data Collection Plan
• Task 3.3. Data Collection and Analysis
• Task 3.4. Additional Studies
Task 3.1. Existing Information Review Workshop
West Yost will conduct a workshop with NBRWTP staff to determine what additional information, if collected ahead of time, would best aid design efforts for future NBRWTP expansion, including improved capabilities for treatment of source water during period s of more challenging raw water quality. As part of the workshop, West Yost staff will also review available hard copy documentation from past design and construction projects. West Yost will work with NBRWTP staff to identify documents that would be helpful to digitize and organize for future reference by designers, construction managers, and potential bidders.

Actual collection, digitization, organization and analysis of data and documents will be completed under Task 3.3.

Task 3.2. Sampling and Data Collection Plan
For the parameters identified in the workshop, West Yost will produce a sampling and data collection plan. The plan will describe recommended parameters, locations, frequencies, and durations for sampling.

For non -water quality-based data collection recomm endations, the plan will summarize the type and quantity of data to be collected, and will identify any instruments or other resources needed to gather the data. Additionally, the plan will include Excel -based templates recommended for storing collected data (primarily numerical data) and folder structures recommended for organizing and storing digitized hard copy documents.

Task 3.3. Data Collection and Analysis
Based on recommendations from the workshop, existing hard copy documentation will be digitized by West Yost with assistance from Fairfield staff and will be organized in a logical and searchable format.

Data collected in accordance with the sampling and data collection plan will be incorporated by West Yost into Excel-based spreadsheets. Raw data will be screened for outliers, and preliminary, high-level analysis of summary statistics and trends will be performed. The objective of the analysis will be to id entify any combination of: unforeseen results, confirmation of preliminary assessments, and/or indications that one or more additional studies or process modifications is clearly warranted. The results of the analysis will be presented in a technical memorandum (TM).

Beyond the sampling and data collection needs identified under Tasks 3.2 and 3.3, additional, targeted studies are needed to address concerns related to power availability, pretreatment (flocculation/ sedimentation) facilities, and filtration facilities. Accordingly, the following special studies are included in this scope:
• Distributed Energy Resources (DER) Evaluation
• Pretreatment Challenge Testing
• Filter Challenge Testing
The DER Evaluation involves assessing the potential for Fairfield to make use of its existing photovoltaic array in conjunction with a battery power storage system to allow for more flexible NBRWTP operations during peak demand periods and potentially provide seamless transition from and to the electric utility.

The Pretreatment Challenge Testing involves stress testing each of the three NBRWTP flocculation/ sedimentation units to determine the actual capacity of each unit in comparison to the rated capacity of each. As part of this effort, West Yost will assist with the development of a draft test protocol . Testing would be performed by Fairfield staff with assistance from West Yost.

The Filter Challenge Testing involves analyzing the performance of the existing filters over the full range of historical loading rates, evaluating the impact of the effective size of the granulated activated carbon and sand media layers on filter headloss and run times, and analyzing the relationship between clarified washwater parameters and filter runtimes under a variety of operational scenarios. Based upon the results of this analysis, a protocol will be developed and implemented to test the existing filters at a range of loading rates to better understand their ability to meet performance goals. Testing would be performed by Fairfield staff with assistance from West Yost.

It is expected that NBRWTP staff will conduct the challenge tests, however, 20 hours has been included to provide as needed on -site assistance. A subconsultant will be retained by West Yost to collect media core samples.

For each of these additional studies, draft and final TMs will be produced to document the findings.

Task 3 Assumptions
• Two workshops with NBRWTP staff; one ahead of testing protocol development and one to review the results of the data analysis and challenge tests.
• One meeting each (three total) with NBRWTP staff to discuss implementation of the three additional studies
• One meeting with DDW to discuss pretreatment testing protocol • City staff will extract data and collect and analyze samples with limited assistance from West Yost commensurate with an agreed budget allocation
• The budget includes an allowance for subconsultant services that will be adjusted when the media sampling scope is determined

Vacaville is faced with important decisions regarding the buildout of its water supply portfolio and needs to more clearly define its future surface water and groundwater supply mix. Of particular importance, the continued use of existing facilities needs to be defined, including its Diatomaceous Earth Water Treatment Plant (DEWTP) and several of its existing water supply wells, which are aging and experiencing water quality issues due to contaminants of concern (i.e., Cr6+). These issues are relevant to th e expansion of the NBRWTP as assumptions made for other City facilities directly impact the allocation of treatment capacity needed for Vacaville and cost allocations between the two Cities. Accordingly, Vacaville needs to finalize its plan for using NBRWTP capacity, in both the near/medium -term and the long -term. Key subtasks to be performed under Task 4 include:
• Task 4.1. Refinement of Demand Projections
• Task 4.2. Evaluation of Surface Water and Groundwater Supply Options • Task 4.3. Vacaville Capacity Strategy TM
Each of these tasks are described further in the following sections.

Task 4.1. Refinement of Demand Projections
The City of Vacaville completed a Water Master Plan Update (Vacaville WMPU) in February 2023 that examined different water supply alternatives in light of growing water demands and emerging water quality concerns. The demand projections developed as part of the Vacaville WMP are based on a series of conservative assumptions and development information available at the time of preparation of the Vacaville WMPU. In this task, demand projections will be reviewed to better define Vacaville’s surface water needs in both the near/medium -term and the long -term. This includes reviewing updated production information and determining if demand trends are growing at a rate similar to or less than what was defined in the Vacaville WMPU.

Task 4.2. Evaluation of Surface Water and Groundwater Supply Options The Vacaville WMPU considered two different surface water treatment options: (1) construction of a new WTP facility, (2) expansion of its share of the NBRWTP coupled with a rebuilding of the DEWTP. The WMPU did not, however, consider consolidating all surface water treatment at the NBRWTP. In addition, as mentioned above, the City’s existing groundwater well facilities have been impacted by CR6+. Recently issued regulations for Cr6+ have impacted Wells 3, 9, 14, 15, and 16, which all have concentrations of Cr6+ that exceed the MCL of 10 micrograms per liter. As a result, future surface water supply planning should factor in the need for blending and/or planned wellhead treatment options as well as considering

increased surface water supplies. Under near-term conditions the City will likely need to rely on additional surface water deliveries in the interim while it concurrently works on addressing wells with Cr6+.

Using the update d demand projections developed under Task 4.1, t he evaluation of additional supply alternatives will be accomplished as follows:

1. Conduct a Supply Strategy Alternatives Workshop to identify which new long-term and interim supply alternatives will be modeled to determine treatment and conveyance capacity needs under both near-term and long-term demand scenarios. During the workshop West Yost and City staff will agree on up to four scenarios to be evaluated using the City’s hydraulic model to identify infrastructure and associated sizing. The following parameters will be agreed upon for each scenario to be evaluated:
a. Demand Scenario: Buildout, Long-term (Pre-Buildout), or Interim (near term / mid term). b. Status of DE Plant: Converted to Storage/Blending facility, or Fully Abandoned. c. Treatment Location: NBR Capacity plus (if any) Capacity within Vacaville d. Groundwater Wells: Producing at Sustainable Yield, or Producing at Less Than Sustainable Yield due to loss of capacity for Cr6+ mitigation.

Based on conversations with City staff and internally, the following alternatives are likely examples of the four scenarios that will be refined and adopted at the workshop for subsequent modeling:

Option A: Buildout Scenario
• Demands: Buildout per the WMPU or refined based on Task 4.1 • Wells producing at the sustainable yield
• DE plant site used only for blending of water from selected wells • NBR producing the balance of supply needed to meet demands Option B: Highest Potential Need from NBR
• Same as Option A, except reduced well production
• Possible Variation: Use long-term (pre-buildout) demands Option C: Interim Conditions (tests near-term adequacy of existing conveyance) • Demands projected for near- to mid-term
• All wells impacted by Cr6+ assumed to be offline
• DE plant not operational
• NBR producing the balance of supply needed to meet demands Option D: Interim Condition with Full Groundwater
• Same as Option C, except wells producing at the sustainable yield • DE plant site used only for blending of water from selected wells

2. Perform a hydraulic evaluation of the identified alternatives to assess the improvements necessary to meet demands. The evaluation will include preparing planning-level estimates of capital costs for each evaluated scenario.

3. Meet with City staff to review the results and select project criteria for the NBRWTP Expansion Program. Specifically, what near -term and long -term capacity is needed at the NBRWTP for Vacaville, and what near-term and long-term offsite improvements are needed to accommodate the NBRWTP supply.

Task 4.3. Vacaville Capacity Strategy TM
Upon completion of the investigations performed under Tasks 4.1 and 4.2, a TM of findings will be produced that will document decisions about Vacaville’s capacity needs from the NBRWTP , including conceptual offsite transmission facilities. A draft TM will be produced for Vacaville staff review and will be finalized based on comments and input received. Fairfield’s NBRWTP capacity needs will be summarized under Task 5.

Task 4 Assumptions
• One workshop with Vacaville staff to discuss the parameters of the modeling to be performed under Tasks 4.2.
• Hydraulics will be evaluated for up to four scenarios • One meeting with Vacaville staff to discuss and agree on a basis for Vacaville’s NBR capacity needs and offsite infrastructure.

Task 4 Deliverables
• Agenda and summary notes for the workshop and meeting with Vacaville staff • Draft and final NBRWTP Capacity Strategy TM
TASK 5. FACILITIES PLANNING
Under this task, facilities planning will be performed that results in a Benchmark Project that will provide the basis for the detailed design of NBRWTP improvements by a suitable design team to be selected at a later time. The facilities planning will def ine and evaluate a potential capacity phasing for meeting near - and long-term capacity needs and will include a planning level cost estimate. The Facilities Plan will be based on the findings and conclusions of the May 24, 2024 technical memorandum (TM) titled “NBRWTP Condition Assessment, Performance Evaluation, and Expansion Analysis” (May 2024 NBRWTP TM), supplemented as described below. The key subtasks to be performed under Task 5 include:
• Task 5.1. Raw and Treated Water Quality Characterization • Task 5.2. Existing Facilities Description
• Task 5.3. Need for Project
• Task 5.4. Treatment Performance and Technology Goals
• Task 5.5. Benchmark Project Development
• Task 5.6. Project Implementation and Schedule
• Task 5.7. Cost Estimates
• Task 5.8. Benchmark Design Report

City of Vacaville

Task 5.1. Raw and Treated Water Quality Characterization West Yost will update historical raw and treated water quality characterizations prepared as part of Fairfield’s recent Public Utilities Master Plan (PUMP), which included available data from 2018 to 2022.

More recent data from 2022 through 2024, including parameters recorded as a result of data collection activities under Task 3, will be incorporated into the PUMP datasets and analyses. The intent of this task is to prepare a comprehensive set of relevant source water quality and plant performance data for use by a plant expansion design team.

Task 5.2. Existing Facilities Description
Descriptions of existing NBRWTP facilities from Fairfield’s recent PUMP will be updated and expanded, as appropriate, to provide additional background on the NBRWTP and its relationship with major treated drinking water infrastructure in Fairfield and Vacaville.

Task 5.3. Need for Project
West Yost will prepare a summary of the need for the proposed NBRWTP improvements, incorporating results from the PUMP (including condition-, capacity-, and performance-based drivers), as well as Tasks 3 and 4 from this scope of work. The principal changes to information previously developed as part of Fairfield’s PUMP will be an updated presentation of capacity -based improvement needs to reflect Vacaville’s capacity requirements, and to update discussion of performance -based improvements reflecting results from Tasks 3.3 and 3.4.

Task 5.4. Treatment Performance and Technology Goals
This task will focus on identifying and defining the Cities’ preferences and expectations for the characteristics and performance of an expanded and modified NBRWTP, including definition of acceptable treatment technologies and equipment. West Yost will le ad a workshop with representatives from both cities to identify and assess a range of technically feasible approaches to modifying and expanding the NBRWTP. A framework will be developed for screening options. Screening criteria may include (but are not limited to) constructability, capital and operating costs, treated water quality, operational flexibility, and ability to meet anticipated and/or potential changes to treated water quality regulations. A TM summarizing and documenting the Cities’ preferences and expectations will be prepared; the TM will serve as the basis for establishing relevant constraints and/or prescriptive requirements for incorporation into future project procurement documents. The purpose of this task is not to confine the future des ign to specific technologies, but rather to identify any constraints that the Cities desire to imposed on the future design.

Task 5.5. Benchmark Project Development
The purpose of the Benchmark Project will be to identify and define one approach to satisfying the Cities’ needs for improvements to the NBRWTP and related offsite infrastructure that would be included in a combined project. The Benchmark Project will establish the type, size, configuration, and performance of key project elements that the Cities’ believe would achieve the project’s capacity and performance requirements, and will serve as the basis for estimated capital and operating costs for the improved facilities. Where appropriate, the Benchmark Project is anticipated to include a degree of conservatism in terms of design criteria, operational complexity, cost, and site planning.

West Yost will lead a joint Project Scoping Workshop to identify which offsite infrastructure projects will be included in a combined project with the NBRWTP improvements, and which offsite project will proceed in parallel as separate projects. The scope of offsite projects to be considered for Vacaville will be based on findings developed under Task 4. The scope of offsite projects to be considered for Fairfield (if any) will be based on the PUMP with input from City staff.

Development of the Benchmark Project will include updates and refinements to facility -specific discussions in Fairfield’s PUMP, modified to reflect the results of Task 3, Task 4, and Task 5.4 of this scope of work. Design criteria will be presented in suff icient detail to communicate the Cities’ performance expectations and preferences, and to provide a basis for evaluation of future proposals for design and construction of the improvements.

Key deliverables prepared under this subtask will include design criteria tables and conceptual site plans for the NBRWTP and selected offsite improvements, including conceptual pipeline alignments.

Task 5.6. Project Implementation and Schedule
The objectives of this task will be to identify and characterize – in sufficient detail for planning purposes – the types, sequencing, and durations of the various steps necessary to implement the project. West Yost will work with the Cities to outline req uirements for environmental documentation and permitting, non - environmental permitting, land acquisition, procurement document development, bid/proposal evaluation, design and construction, facility startup and commissioning, and project closeout. A project schedule will be developed with appropriate durations, relationships, and sequencing of key activities.

Environmental consultant input may be warranted during this subtask, and may be added to the scope and budget if determined to be necessary.

Task 5.7. Cost Estimates
Capital and operating cost estimates will be developed for the Benchmark Project, as well as the supporting engineering, environmental, land acquisition, legal, other administrative activities necessary to support the project. Construction costs will rely primarily on parametric estimating tools incorporating actual facility cost data from recently constructed projects, and will be supported where necessary with more focused, quantity-based estimates for certain facilities. Operating costs will rely on the estimated power, chemical, labor, and equipment replacement and repair needs associated with the Benchmark Project. A 20- to 30-year lifecycle cost analysis will be prepared to combine capital and operating costs.

Task 5.8. Benchmark Design Report
Based on the May 2024 NBRWTP TM, depending on the updated capacity and phasing plan, treatment improvements are expected to include intake screening, ozonation facilities, flash mixing, pretreatment trains (i.e., flocculation/sedimentation basins), dual me dia filters, washwater equalization basins, washwater clarifiers, and sludge lagoons. Other onsite improvements include yard piping, electrical improvements, pumping and metering facilities, and chemical storage. Offsite improvements may include treated water transmission, blending, storage and pumping facilities. The capacity and phasing options will be based on those presented in the May 2024 NBRWTP TM and one of the options will be refined based on discussions with the staff of both Cities. The improveme nt and options defined in Tasks 5.1 through 5.4 will serve as the basis for preliminary site layouts showing the expanded NBRWTP.

The likely CEQA documentation and actions will be identified, and will affect both the costs and schedule for improvements. Similarly, an assessment of environmental permits and non -environmental permits (e.g., encroachment permits) will be performed. Additionally, potential property purchases an d/or easement acquisitions will be identified.

Upon completion of Tasks 5.1 through 5.7, all of the activities under Task 5 will be documented in a Benchmark Project Report that will be submitted to the appropriate staff from both Cities for review and comment.

Task 5 Assumptions
• Three meetings with the staff of both Cities to discuss improvements, options, layouts, criteria, costs, and schedule
• Hydraulic evaluations (if needed) to further define offsite improvements for Fairfield would be performed under separate contract, or under an added scope and budget for this task • Meetings with environmental and/or regional water agencies will be identified but are not included in this scope

Several potential funding mechanisms exist to support the expansion of the NBRWTP. Funding is expected to include some combination of water rates, connection fees, low-interest loans, and/or state and federal grants. Rate studies will be performed independently by both Cities, and it is assumed that a financing plan will be developed by others, as needed to support the internal funding strategy.

The focus of this task will be on the identification of loan and grant funding options available to support the NBRWTP expansion. If warranted, future scope and budget authorizations may include assistance in preparing funding applications, construction labor compliance monitoring, grant/loan administration, and reporting. The initial key subtasks include:
• Task 6.1. Funding Research
• Task 6.2. Meetings with Funding Agencies
• Task 6.3. Funding Strategy TM

Subject: North Bay Regional Water Treatment Plant Expansion and Pipeline Project Environmental Planning Support Services
Dear Mr. Pelz:

Thank you for the opportunity to assist you with the North Bay Regional Water Treatment Plant Expansion and Pipeline Project (Project). LSA will provide environmental planning services to support the development and environmental clearance of the North Bay Regional Water Treatment Plant Expansion and Pipeline Project (Project) in coordination with West Yost. The scope of work includes project mobilization, technical studies, environmental documentation under CEQA (and NEPA, if required), coordination to support the pipeline alignment study, and federal and State permitting.

Page 495 of 1351 ends

3 8/14/25 (Z:\01-Proposals\01-Proposals by Year\2025\Environmental Planning\20252263.P West Yost_North Bay WTP) Planning, and Conservation (IPaC) System, technical reports regarding flora and fauna with potential to occur near the Project areas, and other planning documents completed for projects within the region that have potential relevance to the Project area. • Perform a reconnaissance-level field survey. Goals of the biological field survey include identification of existing biological resources within the Project area, including land uses and biotic habitats, constituent plants and animals, and suitable habitat for special status species. • Prepare a Biological Evaluation memorandum evaluating potential project impacts to State and federally listed or special status species, habitats, and other sensitive biological resources and include NEPA Section 7 consultation analysis to assist with federal grant compliance needs. The memo will also provide avoidance and minimization measures to assist design and provide possible mitigation reductions, where possible. This estimate includes one set of comments from the client and one round of minor comments from the City (requiring a total of 8 hours or less) in response to the Draft Report.

Task 2.1.2 Cultural Resources Study
LSA proposes to conduct an archaeological and architectural inventory, including a Class III intensive pedestrian survey and a cultural resources inventory report summarizing the results of the study, to assist in compliance requirements set for the by the City of Fairfield as lead agency. LSA will complete the report in accordance with the Secretary of the Interior’s Standards and Guidelines for Archaeology and Historic Preservation (48 FR 44716, September 29, 1983) and the California Office of Historic Preservation (OHP). The cultural resources inventory report is a summary document used by the applicant as a consultation and decision-making document. The preparation of the report includes the following tasks as necessary components, and the results of these tasks will be summarized in the report:
• GIS Mapping. LSA will develop project area mapping in consultation with the owner/ representative that depicts location, vicinity, project area footprint, records search, and ethnographic maps. The project area, developed in coordination with the applicant, is defined as the area within which a project may directly or indirectly cause changes in the character or use of historic properties, should any be present. For historic architectural resources, indirect changes (such as visual or vibratory effects) may occur in parcels adjacent to the proposed project area.
• Record Search/Research. LSA will conduct a records search of the project area and surrounding

0.5-mile radius through the Northwest Information Center (NWIC) of the California Historical Resources Information System (CHRIS) housed at California State University, Sonoma. The purpose of this records search is to obtain and review archaeological reports and cultural resources previously recorded within the project area and 0.5-mi buffer, to inform assessments of built environment and other cultural resources that may be at risk of adverse effects as a result of proposed project activities. LSA will also consult other sources, including historic-period

Page 496 of 1351 ends

4 8/14/25 (Z:\01-Proposals\01-Proposals by Year\2025\Environmental Planning\20252263.P West Yost_North Bay WTP) maps and aerial photographs, to inform land use patterns and the site’s sensitivity for surface and subsurface archaeological cultural resources within the project area. • Pedestrian Survey. After receiving the records search results, an LSA archaeologist will conduct a cultural resource inventory of the project area. This cultural resource inventory will be implemented as a Class III intensive pedestrian survey of the project area, in accordance with the Secretary of the Interior’s (SOI) Standards and Guidelines for Archaeology and Historic Preservation (48 FR 44716, September 29, 1983). Fieldwork will be directed and documented by an LSA archaeologist individually meeting the SOI Professional Qualifications Standards (36 CFR 61 and 48 FR 44716) for archaeology and an archaeologist crew member supervised by the SOI- Professionally Qualified archaeologist. As there is currently no specified project area footprint, this scope assumes the pedestrian survey will take place on an approximately 148-acre area containing and immediately surrounding the North Bay Regional Water Treatment Plant (NBRWTP) facility in Solano County, California. Any necessitated increase in survey area will require a contract amendment and a schedule adjustment may be necessary. • Cultural Resources Inventory Report. Upon completion of the preceding tasks, LSA will prepare a Draft and Final Cultural Resources Inventory Report. The report will include the natural context and historic and ethnographic contexts pertaining to the project region, along with a records search and literature review, Tribal consultation summaries if applicable, field methodologies, survey results, anticipated negative findings (see below), and recommendations for cultural resource management strategies (if applicable). This estimate includes one set of comments from the client and one round of minor comments from the City (requiring a total of 8 hours or less) in response to the Draft Report.

Task 2.1.3 Air Quality and Greenhouse Gas Emissions Analysis LSA will prepare an Air Quality and Greenhouse Gas Technical Memorandum for the proposed project in response to the Environmental Checklist questions. LSA will assess the proposed project’s impacts related to air quality and climate change (greenhouse gas [GHG] emissions). LSA will perform the analysis consistent with applicable City of Fairfield and the Bay Area Air District (Air District) procedures and requirements.

Construction activities associated with project development, including grading and ground disturbance, could increase concentrations of particular matter. This increase could contribute to existing air pollution and has the potential to exceed regional air emission thresholds established by the City of Fairfield and the Air District. The proposed project would also generate GHG emissions.

Typically, an individual project does not generate sufficient GHG emissions to influence climate change significantly on its own; therefore, the issue of climate change is cumulative in nature. The proposed project would generate GHG emissions that would cumulatively contribute to climate change.

Following the Air District guidelines, LSA will prepare a draft Air Quality and Greenhouse Gas Technical Memorandum to identify existing air quality conditions and potential air quality and greenhouse gas impacts resulting from the proposed project, by undertaking the following subtasks:

Page 497 of 1351 ends

5 8/14/25 (Z:\01-Proposals\01-Proposals by Year\2025\Environmental Planning\20252263.P West Yost_North Bay WTP) • Describe Existing Environmental Setting: LSA will provide a brief summary of information related to air quality and global climate change along with the climate/meteorological conditions in the project vicinity.
• Describe the Existing Regulatory Framework: The existing regulatory framework for air quality and global climate change will identify applicable federal, State, and City of Fairfield policies, regulations, and programs.
• Determine the Project's Consistency with Adopted Plans. LSA will review adopted plans related to clean air and the reduction of greenhouse gas emissions in the State of California, the Bay Area Air District, and the City of Fairfield, and determine the project's consistency with these plans.
• Assess Project Construction Emissions. Construction activities associated with the proposed project would generate increased particulate emissions associated with site preparation, grading, soil hauling, and other construction activities on the project site. Construction equipment exhaust would also be a known source of air pollution. LSA will calculate the regional construction emissions using the California Emissions Estimator Model version 2022.1 (CalEEMod).
• Assess Project Operation-Period Air Quality Impacts. Regional emissions of criteria air pollutants associated with long-term operations from vehicle trips will be calculated with CalEEMod. In addition, emissions associated with stationary sources, such as on-site energy consumption and landscaping equipment will be estimated. • Health Risk Assessment: Based on the project location and nearby sensitive receptors, LSA will prepare a construction health risk assessment (HRA) that will summarize cancer risk and non- cancer risk (chronic and acute) and will compare the results of the HRA with the SJVAPCD’s recommended thresholds. Supporting modeling and technical information for the HRA will be attached to the memorandum as an appendix.
• Assess Project Greenhouse Gas Emissions. LSA will qualitatively evaluate the project’s impact on greenhouse gas (GHG) emissions by providing an assessment of greenhouse gas thresholds identified in the Bay Area Air District’s 2022 CEQA Guidelines. Consistent with the Air District’s CEQA Guidelines and State CEQA Guidelines Section 15183.5, if a project is consistent with an adopted qualified Greenhouse Gas Reduction Strategy that meets the standards, it can be presumed that the project would not have a significant greenhouse gas emission impact. The City’s Climate Action Plan (CAP) meets the requirements for a qualified Greenhouse Gas Reduction Strategy. As such, LSA will evaluate whether the proposed project would be consistent with the City’s CAP. LSA will also recommend mitigation measures to be consistent with the CAP, as necessary.
• Identify Mitigation Measures: LSA will identify, where necessary, practical mitigation measures to address any significant project or cumulative impacts. Measures established by the Air District

Page 498 of 1351 ends

6 8/14/25 (Z:\01-Proposals\01-Proposals by Year\2025\Environmental Planning\20252263.P West Yost_North Bay WTP) for dust suppression will be identified to reduce construction impacts. Mitigation measures designed to reduce the project's short-term construction and long-term air quality and GHG impacts to the extent feasible will be identified, if needed. Both an evaluation of the potential mitigation measures and a discussion of their effectiveness will be provided. • Prepare Memorandum. LSA will submit one digital copy of the draft Memorandum to the project team for review. Based on one set of comments, LSA will prepare a final Memorandum.

This estimate includes one set of comments from the client and one round of minor comments from the City (requiring a total of 8 hours or less) in response to the Draft Report.

LSA will submit a digital copy of the draft Air Quality and Greenhouse Gas Technical Memorandum to the project applicant for review. Based on one set of consolidated comments, LSA will prepare a final Air Quality and Greenhouse Gas Technical Memorandum, to be delivered to the project applicant in PDF Format.

Task 2.1.4 Noise Impact Analysis
LSA will prepare a noise and vibration analysis for the project in response to the Environmental Checklist questions in Appendix G of the State CEQA Guidelines. LSA will prepare a technical noise and vibration impact analysis consistent with all applicable local jurisdiction procedures and requirements as well as applicable vibration standards identified by the California Department of Transportation (Caltrans) and the Federal Transit Administration (FTA). The Noise and Vibration Impact Analysis will be completed by undertaking the following subtasks:
• Applicable Standards and Existing Environment: LSA will prepare a technical noise and vibration impact analysis consistent with all applicable City procedures and requirements and applicable vibration standards identified by the California Department of Transportation (Caltrans) and the Federal Transit Administration (FTA). LSA will analyze the potential noise and vibration impacts compared to the Cities of Fairfield and Vacaville Noise Elements and Municipal Code Noise Ordinance criteria, as applicable.

LSA will conduct up to two long-term ambient noise level measurements within the project area.

The long-term ambient noise level will be documented for 24 hours. These ambient noise levels will be used to assess the existing ambient noise environment in the project vicinity. • Construction Noise Impact Analysis: LSA will analyze the short -term construction noise and vibration impacts on adjacent noise-sensitive uses. Construction would occur during implementation of the project. Noise impacts from construction sources will be analyzed based on the equipment expected to be used, the length of a specific construction task, the equipment power type (gasoline or diesel engine), horsepower, load factor, and the percentage of time in use. FTA-recommended or industry -recognized empirical noise emission levels will be used for the construction equipment. The construction noise impact will be evaluated in terms of maximum levels (L
max), and the frequency of occurrence at adjacent sensitive locations. Analysis requirements will be based on the sensitivity of the area and the Cities’ criteria. Noise abatement

7 8/14/25 (Z:\01-Proposals\01-Proposals by Year\2025\Environmental Planning\20252263.P West Yost_North Bay WTP) measures designed to reduce short-term impacts to acceptable noise levels in the vicinity of the project site will be determined where necessary.
• Construction Vibration Impact Analysis: Vibration impacts from construction sources will be analyzed based on the equipment expected to be used. The FTA -recommended equipment vibration levels will be used for the construction equipment expected to be used. The construction vibration impact will be evaluated in terms of peak particle velocity (PPV, or inches per second [in/sec]) and the vibration decibel levels for building damage and human annoyance, respectively.

Analysis requirements will be provided based on the sensitivity of the ar ea directly adjacent to the project site.

• Off-site Stationary Noise Analysis : Long-term noise impacts associated with the proposed equipment will be evaluated. The City and County noise criteria for stationary sources will be used to assess potential stationary source noise impacts. Using the project site plan, LSA will determine future stationary sources noise impacts from proposed project incorporating equipment noise specifications from the manufacturers or published noise levels from similar equipment.

• Mitigation Measures: If necessary, LSA will determine temporary construction-related noise and vibration reduction features which can be incorporated into the project plans, designed to reduce short-term construction noise and vibration impacts, as well as long-term operational impacts. • Noise and Vibration Report: LSA will summarize the above findings in a draft technical report that will also include the settings and regulatory requirements. LSA Noise Staff will respond to one round of consolidated comments from the client and Cities after which a Final Noise and Vibration Impact Analysis memorandum will be provided. This estimate includes one set of comments from the client and one round of minor comments from the City (requiring a total of 8 hours or less) in response to the Draft Report.

Task 2.1.5 Water Quality and Hydrology Technical Memorandum.

LSA will prepare a Hydrology and Water Quality Report that evaluates project-related and cumulative impacts to water quality, groundwater, hydrology, and floodplains. • The Hydrology and Water Quality Report: LSA will prepare a report that includes a discussion of the existing setting, applicable federal, State, regional and local regulations, and applicable CEQA significance thresholds related to hydrology and water quality. The impact analysis will include a qualitative response to each of the CEQA thresholds in Appendix G of the State CEQA Guidelines. LSA will evaluate the need for best management practices (BMPs) to ensure compliance with federal, State, and local National Pollutant Discharge Elimination System (NPDES) permit requirements and local ordinances during construction and operation. However, because the analysis is at a programmatic level, the Hydrology and Water Quality Report will not specify specific construction, source control, site design, low impact development, design pollution prevention, or treatment control Best Management Practices (BMPs) or drainage improvements. This estimate includes one set of comments from the client and one round of

Subject: North Bay Regional Water Treatment Plant Expansion and Pipeline Project Environmental Planning Support Services
Dear Mr. Pelz:

Thank you for the opportunity to assist you with the North Bay Regional Water Treatment Plant Expansion and Pipeline Project (Project). LSA will provide environmental planning services to support the development and environmental clearance of the North Bay Regional Water Treatment Plant Expansion and Pipeline Project (Project) in coordination with West Yost. The scope of work includes environmental documentation under CEQA (and NEPA, if required, technical studies, and federal and State permitting.

Note: This scope and budget builds upon the previously executed NTP for Phase 1: Preliminary Assessment Assistance (Tasks 1.1 and 1.2), and therefore starts at Phase 2.

PHASE 2: PROJECT MANAGEMENT
Task 2.1: Project Management and Coordination
Project Management will include the oversight of all LSA staff working on the Project and will be responsible for managing the day-to-day activities associated with the Project. Responsibilities include regular coordination with West Yost staff, contract management, oversight of the Project team, schedule coordination, and development of work products. Each month, the Project Manager will provide West Yost Project Manager with regular updates regarding the status of work and scheduled deliverables. The budget includes 2 one-hour meetings a month for 6 months following 1 one-hour meeting for an additional 6 months.

Task 2.2: Project Description
LSA will prepare a Project Description that includes a description of the Project site’s location and characteristics, background information, Project components, and the required City approvals. A location map and graphics illustrating the Project will also be developed based on materials provided by the Project Applicant. LSA will submit the draft Project description to City staff for review and comment and will subsequently prepare a final Project description for distribution to the LSA team technical specialists before initiating technical analyses.

2 12/19/25 (Z:\01-Proposals\01-Proposals by Year\2025\Environmental Planning\20252263.P West Yost_North Bay WTP) PHASE 3: TECHNICAL STUDIES
LSA will prepare the necessary technical studies to support CEQA compliance and NEPA compliance with Section 7 and 106. Anticipated studies include:

Task 3.1 Biological Evaluation
LSA will prepare a Biological Resource Assessment (BRA) report including a summary of the results of the literature review, biological resources survey, and an assessment of whether focused surveys are needed. The following biological resources scope includes:
• Research. Review of relevant background information, including but not limited to California Natural Diversity Database, the California Native Plant Society’s Inventory of Rare and Endangered Vascular Plants of California, United States Fish and Wildlife Service’s (USFWS’s) Information, Planning, and Conservation (IPaC) System, technical reports regarding flora and fauna with potential to occur near the Project areas, and other planning documents completed for projects within the region that have potential relevance to the Project area.
• Reconnaissance-Level Survey. Perform a reconnaissance-level field survey. Goals of the biological field survey include identification of existing biological resources within the Project area, including land uses and biotic habitats, constituent plants and animals, and suitable habitat for special status species.
• Report. Prepare a Biological Evaluation memorandum evaluating potential project impacts to State and federally listed or special status species, habitats, and other sensitive biological resources and include NEPA Section 7 consultation analysis to assist with federal grant compliance needs. The memo will also provide avoidance and minimization measures to assist design and provide possible mitigation reductions, where possible. This estimate includes one set of comments from the client and one round of minor comments from the City (requiring a total of 8 hours or less) in response to the Draft Report. This document will be used to support CEQA and NEPA findings. • Focused Surveys. LSA will also conduct protocol level surveys for Contra Costa goldfields and Crotch’s bumble bee which we do not have direct information on presence or absence. Protocol surveys for Contra Costa goldfields will be conducted in April/May 2026 (depending on blooming conditions for nearby populations) and for Crotch’s bumblebee a minimum of three surveys between April through August 2026.
• Report. LSA will also prepare a supplemental survey report addressing Contra Costa goldfields and Crotch’s bumble bee protocol surveys. These studies and report will support permitting and preconstruction efforts.

Task 3.2 Cultural Resources Study
LSA proposes to conduct an archaeological and architectural inventory, including a Class III intensive pedestrian survey and a cultural resources inventory report summarizing the results of the study, to assist in compliance requirements set for the by the City of Fairfield as lead agency. LSA will complete the report in accordance with the Secretary of the Interior’s Standards and Guidelines for Archaeology and Historic Preservation (48 FR 44716, September 29, 1983) and the California Office of Historic
