DATE: November 25, 2025
FROM: Stephanie Killingsworth, Public Works Financial Analyst SUBJECT: Consideration and Proposed Approval of a Resolution Authorizing the City Manager to Execute a Professional
Services Agreement with Sherwood Design Engineers for
Civil Engineering Services for the Mills Lane and Highway 29 Improvements Project in an amount not-to-exceed
$91,000 and Establishing Capital Improvement Plan
Project No. R26-06 - Mills Lane Realignment and
Intersection Improvements.
RECOMMENDED
ACTION:
Staff recommends approval of the attached Resolution.
PREVIOUS COUNCIL
ACTION:
None.
STATEMENT OF THE
PURPOSE:
To authorize design services related to the Mills Lane
Realignment and Intersection Improvements.
FINANCIAL IMPACT: The total financial impact is an amount not-to-exceed $91,000, to be funded from Traffic Mitigation Impact Fees (Fund 740).
BACKGROUND:
The proposed project advances long-planned right-of-way improvements at the intersection of Mills Lane, Grayson Avenue, and Highway 29.
These improvements were originally part of the Farmstead Lodging Project's conditions of approval and have been on hold since the private project's deferral. To address existing traffic safety and access deficiencies, the City now intends to move forward with design and permitting for these public improvements independent of the private development.
It should be noted that the Farmstead development will still be obligated to compensate the City for their proportionate share of the project costs as delineated in the Development Agreement.
Sherwood Design Engineers was previously the engineer for the record for these plans and possesses the relevant background materials and agency coordination experience.
Re-engaging Sherwood Design Engineers will allow the City to efficiently update existing design documents and resume permitting with Caltrans, the California Public Utilities Commission, and other stakeholders without re-starting the process.
Agenda Item #10.7.
DISCUSSION:
Sherwood's proposal outlines engineering services for:
Intersection Improvements - Permit documents, permitting support, and construction documents for the revised intersection at Highway 29 and Grayson Avenue, including railroad crossing coordination.
Mills Lane Realignment - Design and permitting for the realignment connecting to Highway 29 consistent with the previous Farmstead Development Agreement. Stormwater Control and Storm Water Pollution Prevention Plan Preparation. Project Management and Construction Administration support on a time-andmaterials basis during construction.
Staff has reviewed the proposal and determined that the scope of services is consistent with the City's project needs and industry standards. The proposed fee is reasonable for the scope and timeline of work.
Approval of this agreement will enable design work to commence immediately, allowing staff to proceed with Caltrans and the California Public Utilities Commission permitting.
Following completion of design and permitting, staff will return to Council for authorization to bid construction.
ENVIRONMENTAL REVIEW: Not a CEQA Project.

RECOMMENDED
ACTION:
Approve the resolution.
PREVIOUS COUNCIL
ACTION:
6/22/1993 Resolution No. 93-58 - Adoption of Water and
Sewer Technical Standards
11/23/1993 Resolution No. 93-134 - Adoption of Streets, Storm and Sidewalk Technical Standards

Storm and Sidewalk Standards
11/27/2015 Resolution No. 2015-132 - Revision of Trench Standards
STATEMENT OF THE
PURPOSE:
The purpose of this action is to approve an update to the City of St. Helena Design and Construction Standards.
FINANCIAL IMPACT: None
BACKGROUND:
The City Design and Construction Standards are a collection of graphical exhibits and instructions which define the means, methods, configurations and products to be used by contractors who perform work within the City Right-of-Way and on City infrastructure.
All contractors performing work within the City are required to adhere to these standards to ensure consistency, safety, and quality of the public infrastructure. The Design and Construction Standards specify a wide variety of public infrastructure ranging from the widths of streets and sidewalks to detailed instructions regarding the installation of water pipelines.
The current collection of Design and Construction Standards were developed and approved in 1993 and 1998 with revisions in 2015. The Standards are due to be updated to reflect updates in products, materials, methods and construction practices.
In 2019, Staff initiated an update to its existing City Design and Construction Standards.
DISCUSSION:
The 2019 update effort stalled for a variety of reasons and in 2024 Staff reinitiated the update effort. City Engineering and Operations Staff conducted a comprehensive review of the City’s Design and Construction Standards. The review and update to the standards has been completed, which have been modified to reflect current industry Agenda Item #10.8.
practices, updated materials, configurations and construction methods. The table of contents of the updated standards and an example of an updated standard is found in Attachment 1.
There are two major categories of content which has been updated. The first are updates that include revisions to products and materials which now align with technological and industry advances. This includes items such as pipe materials, pipe systems, concrete and asphalt concrete mix designs, materials, and safety devices.
The second are updates that include revisions to design standards and methods. This includes items such as pedestrian facilities, roadway striping, trenching methods and surface restoration, utility layouts and separations, inspection and disinfection procedures. These updates are essential to ensure the continued safety, reliability, and efficiency of the City's public infrastructure.
The updated standards are posted on the City's website and can be viewed at https://cityofsthelena.gov/921/7636/Public-WorksStandards?activeLiveTab=widgets.Upon approval by the City Council, the City will officially transition to distribution and use of the updated City Standards.

Agenda Report to the City Council
Agenda Section: CONSENT ITEMS
Department: Public Works
DATE: November 25, 2025
FROM: Stephanie Killingsworth, Public Works Financial Analyst SUBJECT: Consideration and Proposed Adoption of a Resolution Authorizing a Budget Amendment to Appropriate Water
Enterprise Fund Balance for the Stonebridge Well Filter Media Replacement with ERS Industrial Services, Inc.
increasing appropriations by $190,590 using Water
Enterprise Fund Balance.
RECOMMENDED
ACTION:
Staff recommends approval of the attached Resolution.
PREVIOUS COUNCIL
ACTION:
Resolution 2025-111 - City Council approved a
Construction Contract with ERS Industrial Services, Inc. with an authorized total project budget of $190,590 to be paid with FY2025/26 Water Enterprise Operating Budget.
STATEMENT OF THE
PURPOSE:
This item seeks City Councils approval of a budget
amendment only. During implementation, staff determined that sufficient appropriations were not available within the FY25/26 Water Enterprise Operating Budget to support the approved Project. Therefore, City Council authorization is required to appropriate use of Water Enterprise Fund
Balance to fund the project.
FINANCIAL IMPACT: The previously approved project cost of $190,590 was not included in the adopted FY25/26 Water Enterprise Fund
Operating Budget. The prior staff report anticipated that a mid-year budget adjustment may be required to maintain
adequate operational capacity.
Upon further review, staff has determined that no
appropriated funds are currently available within the
current Operating Budget to support this project. As a
result, a budget adjustment is required now, rather than at mid-year, to ensure the project can proceed.
Staff recommends increasing appropriations for 561-5034- 2670 by $190,590 using Water Enterprise Fund Balance.
This action will ensure that sufficient funding is available while maintaining continuity of operations.
BACKGROUND:
Agenda Item #10.9.
The Stonebridge Wells play a critical role in supplementing the City's water supply during high-demand months. In recent years, the City has received periodic customer complaints related to discoloration and aesthetic quality of water, which can partially be attributed to this site. Although the water remains safe and compliant with regulatory standards, staff has been actively working with consultants and treatment specialists to identify operational improvements.
An evaluation of the Stonebridge Well Filter System determined that the filter media, which is responsible for removing naturally occurring constituents such as iron and manganese, has reached the end of its useful life and is no longer performing efficiently.
Replacing the media is necessary to maintain water quality and system reliability.
As part of the City's ongoing efforts to address seasonal water quality issues, staff had an evaluation performed on the condition of the filter media at the Stonebridge Wells.
The existing media has been in place for several years and has shown signs of reduced effectiveness in removing iron, manganese, and other naturally occurring constituents that can contribute to water discoloration, taste, and odor concerns.
ERS Industrial Services, Inc., a specialized environmental remediation contractor, has provided a proposal to remove and replace the aging filter media with new, higherperformance material that is expected to enhance treatment efficiency and improve water quality. The scope of work includes removal and disposal of the existing media, cleaning and inspection of the vessels, supply and installation of a new filter gravel, greensand, provided a proposal to remove and replace the aging filter media with new, higher-performance material that is expected to enhance treatment efficiency and improve water quality. The scope of work includes removal and disposal of the existing media, cleaning and inspection of the vessels, supply and installation of a new filter gravel, greensand, and anthracite, and testing to ensure system optimization following installation.
DISCUSSION:
On September 23, 2025 the City Council approved a Construction Contract with ERS Industrial Services, Inc. for replacement of the media requiring a total budget of $190.590. The scope of work includes removal and disposal of existing media, vessel cleaning and inspection, installation of new filter gravel, greensand, and anthracite, and post-installation testing. The contract terms and scope remain unchanged.
The initial approval assumed that sufficient appropriations were in place within the FY2025/26 Water Enterprise Operating Budget, subject to a possible mid-year budget adjustment. However, during implementation, staff confirmed that current-year operating appropriations cannot support this cost, and the fund does not contain available savings or unused capacity to absorb the expense.
Although the current FY25/26 Water Enterprise Fund Operating Budget does not have adequate appropriated funds, the fund does have sufficient Fund Balance to complete Agenda Item #10.9.
this one-time expense. To proceed with the project, an immediate budget amendment is necessary. This action allows the project to move forward immediately and removes a fiscal constraint identified after the original approval.
ENVIRONMENTAL REVIEW: The project is exempt from CEQA under Section 15301, Class 1 (Existing Facilities), as it involves repair and maintenance of existing public utility systems without expansion of capacity or use.

groundwater regulatory services through June 30, 2027.
FINANCIAL IMPACT: Past Work
Payment for the past regulatory work completed by Larry Walker Associates in the amount of $191,209 is not
appropriated in the FY25-26 Wastewater Enterprise Fund
Operating Budget. Staff recommends using Wastewater
Enterprise Fund Balance to fully fund this outstanding
obligation. These monies include accumulated savings
from prior-year Public Works Administration operating
budgets, which were returned to fund balance at year-end.
New Scope of Services
Funding for the new Professional Services Agreement notto-exceed $160,700 through June 30, 2027 is available within the Public Works Administration operating budget for FY2025-26 and FY2026-27, and no budget adjustment
is required for the new contract at this time.
BACKGROUND:
Larry Walker Associates (LWA) has provided regulatory compliance assistance to the City of St. Helena's Wastewater Treatment and Reclamation Facility WWTP) since 2017. Their work supports the City's compliance with the San Francisco Bay Regional Water Quality Control Board (RWQCB) permits, Water Reclamation Requirements, Sanitary Sewer System Waste Discharge Requirements (WDRs), and various monitoring and reporting mandates.
The City has historically relied on LWA for wastewater regulatory assistance, groundwater monitoring, NPDES compliance reporting, and specialized technical support. Over the past several years, LWA's services have been essential in maintaining the City's compliance with complex and evolving State and regional regulatory requirements.
Past Work
Larry Walker Associates experienced staff turnover and delays in invoicing; however, they continued providing regulatory assistance beyond the expiration of the prior agreement to ensure that the City remained compliant. LWA subsequently submitted four outstanding invoices totaling $191,209.24 (rounded to $191,209 for City Council authorization). LWA's November 13, 2025 cover letter provides itemized past-work totals and a reconciliation of hours, tasks, and deliverables completed.
New Scope of Services
To maintain continuity in regulatory compliance, LWA submitted a new proposed Scope of Services through June 30, 2027, with a total not-to-exceed cost of $160,700. The proposed scope includes ongoing SMRs, pollution prevention reporting, annual reports, Agenda Item #10.10.
groundwater monitoring, mixing zone study updates, assistance with the NPDES permit renewal process, and SSMP updates, among other regulatory requirements.
DISCUSSION:
Past Work Payment Authorization
The past work performed by Larry Walker Associates between February 2023 and October 2025 was necessary to ensure the City remained in compliance. Work performed included:
Monthly and annual Self-Monitoring Reports (SMRs)
NPDES permit renewal application support (ROWD)
Groundwater sampling, lab coordination, and reporting Pollution Prevention Program compliance
Regulatory correspondence and technical support
SSMP audit and update preparation
Operational assistance during staffing shortages and equipment failures These efforts ensured uninterrupted compliance and prevented potential enforcement actions or penalties. Payment authorization is now requested to reconcile the outstanding balance of $191,209 for these completed services.
New Professional Services Agreement
The City continues to face significant and ongoing wastewater regulatory requirements, including anticipated updates to NPDES permit conditions, groundwater monitoring obligations, and mandatory SSMP updates. LWA's 2025-2027 Scope of Services provides comprehensive technical, regulatory, and reporting support needed to maintain compliance. Key components of the new scope include:
Preparation of SMRs, annual reports, and compliance certifications Updates to the Pollution Prevention Program
Support through the NPDES permit reissuance and ROWD process Groundwater monitoring, sampling, and analysis
Mixing zone study coordination and regulatory review
Technical assistance for emerging regulatory issues and RWQCB directives SSMP update and recertification before May 2026 deadline The new PSA establishes a not-to-exceed cost of $160,700 through June 30, 2027.
This agreement formalizes ongoing services and ensures adequate technical support for the City's complex regulatory environment.

AND AUTHORIZING THE NECESSARY BUDGET AMENDMENTS.
RECITALS
A. Larry Walker Associates (LWA) has provided regulatory compliance services to ensure the City’s adherence to State and regional wastewater and groundwater regulatory requirements; and
B. LWA continued providing essential regulatory support beyond the expiration of the prior agreement. Due to LWA’s internal staffing turnover and delays in invoicing, the City did not receive timely invoices for work performed between February 2023 and October 2025; and
C. As a result of these delays, the City now has outstanding invoices totaling $191,209 requiring Council authorization for payment; and D. Payment for these past services was not appropriated in the FY2025-26 Wastewater Enterprise Fund Operating Budget; and
E. Sufficient funding is available within the Wastewater Enterprise Fund Balance, including accumulated savings from prior-year Public Works Administration operating budgets that revered to fund balance at year-end; and F. A budget amendment is required to appropriate these funds for payment.
RESOLUTION
NOW, THEREFORE, the City Council of the City of St. Helena resolves as follows:
1. Authorizes payment to Larry Walker Associates in the amount of $191,209 for past wastewater and groundwater regulatory work efforts.
2. Authorizes a budget amendment appropriating $191,209 from the Wastewater Enterprise Fund Balance to the applicable operating expenditure account to fund this payment.

WASTEWATER AND GROUNDWATER REGULATORY SERVICES: PROGRESS REPORT AND CONTRACTING November 13, 2025
Joseph Leach
City of St. Helena
1088 College Avenue
St. Helena, CA 95574
[email protected]
Subject: Wastewater and Groundwater Regulatory Services: Progress Report and Contracting Dear Mr. Leach,
Larry Walker Associates (LWA) has been providing regulatory assistance to the City of St. Helena (City) since 2005. Most recently, we have been assisting with wastewater compliance for the City’s wastewater treatment plant (WWTRP) under contract 2022-031 and with groundwater monitoring under P.O. 14117.
In the time since these contracts have started, the LWA management team for the City’s contract has undergone staffing changes. Although the initial contract periods have expired, work continued as LWA was committed to ensure the City continued environmental compliance. Invoices for these services were delayed but are now enclosed for your review. Enclosed, please find four invoices covering work efforts for February 2023 to October 2025 for wastewater regulatory assistance (invoices 00110.24-17 and 00110.24- 18) and for October 2024 to October 2025 for groundwater monitoring and reporting (invoices 00110.19-80 and 00110.19-81). In total, the compensation amount for this past work effort is $191,208.24.
The enclosed invoices include detailed information on personnel, hours, and task descriptions on a monthly basis. The work effort completed has always been at the direction of City staff, and has ensured the City’s compliance with requirements mandated by the Regional and State Water Resources Control Boards.
In the period covered by these work efforts, LWA has assisted the WWTRP team through several staffing transitions, helped staff navigate complex regulatory requirements, prepared monthly and annual selfmonitoring reports for the WWTRP, completed the WWTRP National Pollutant Discharge Elimination System (NPDES) permit renewal application, updated the City’s Sewer System Management Plan, and performed groundwater sampling required by the City’s 2016 Cease and Desist Order.
We appreciate your assistance in this matter. Our efforts have ensured uninterrupted compliance and supported the City through critical regulatory transitions. It has always been a pleasure to work with City of St. Helena staff and support the City’s continued commitment to protecting the environment. We look forward to continuing this work and have completed a proposal and scope of services to continue this assistance through June 30, 2027 (submitted separately).
Please let me know if you have any questions. I can be reached at 415-378-2780 or [email protected].
Sincerely,
Alina Constantinescu, Senior Engineer
