Agendas Report to the City Council
Agenda Section: CONSENT ITEMS
Department: Public Works Department
DATE: April 28, 2026
FROM: Rebecca White, Administrative Assistant
SUBJECT: Consideration and approval of a resolution authorizing a temporary closure of a portion of Hunt Avenue on Saturday, June 20, 2026, from 6:00a.m. to 8:00p.m., for a Pride
Celebration event; and (2) authorizing mobile vendors to park and operate on the closed portion of Hunt Avenue
during the event; and (3) a permit allowing the possession of open alcoholic beverages on the closed portion of Hunt Avenue for the event.

RECOMMENDED
ACTION:

Staff recommends approval of the attached resolution.

PREVIOUS COUNCIL
ACTION:

None.

STATEMENT OF THE
PURPOSE:

Authorize the road closure of Hunt Avenue, allow for mobile food vendors to park and operate on the closed portion of Hunt Avenue, and allow for the possession of open
alcoholic beverages on the closed portions of the streets for the 2026 Pride Celebration event.

FINANCIAL IMPACT: There currently is not a financial impact. However, should the applicant choose to seek and receive waived permit
fees for this event, the financial impact could be projected to be as much as $1,375 for required permits related to this event, including a minor encroachment permit, road closure permit, and raw water permit.

CEQA DETERMINATION: Not a CEQA Project (CEQA Guidelines §15378) BACKGROUND:

The Public Works Department has received applications for a minor encroachment permit and a road closure permit to temporarily close a portion of Hunt Avenue on June 20, 2026, for a Pride Celebration event. The applicants are requesting the temporary road closure to facilitate a centrally-located event in the heart of town, focused on creating a community-based and inclusive celebratory event for all ages.

Page 17 of 72 ends

DISCUSSION:

The proposed road closure will take place on Saturday, June 20, 2026, from 6:00a.m. to 8:00p.m., to allow for setup and tear down of the event, as well as the event itself. The event is still in the planning stages, hinging on the approval of City Council before more formal planning and commitments can take place. A letter from the applicant is attached, describing the vision for this event: a small festival with local food vendors, music, dancing, arts & crafts, and more, to bring pride celebreation to St. Helena. The Hunt Avenue location was chosen as it is central to downtown, benefiting both local residents and downtown business owners. While the applicant has not indicated that alcoholic beverages will be sold, the resolution includes language allowing for such activity to provide flexibility in the event planning. The applicant is responsible for securing any applicable ABC licenses should they wish to have vendors with alcoholic beverages at this event.

As stated above, this event is in the preliminary planning stages. While City Council approval authorizes the proposed road closure, the road closure and event may only proceed if the applicant obtains all required permits and complies with all applicable requirements. The applicant is responsible for securing all required permits prior to the start of the event. This includes a noise permit from the Police Department, if applicable, as well as all necessary Public Works permits such as a minor encroachment permit and road closure permit. Staff will work with the applicant to ensure all necessary submittals are received, and that all required City permits are issued prior to the event.

The approval process for the minor encroachment and road closure permits includes coordination between Public Works, Fire, and Police to ensure proper safety measures are in place. The applicant is responsible for acquiring any permits required by Caltrans.

The road closure will be secured with a barricade equivalent to k-rail that will prevent errant vehicles driving through the closed portion of Hunt Avenue. Per the conditions of the road closure permit, the applicant will be responsible for communicating and coordinating with all residences and businesses within a 1,000-foot radius of the road closure, and will coordinate to ensure alternate access for any commercial driveways that may be affected by the closure.

ENVIRONMENTAL REVIEW:

None.

GOAL:

Goal 5: Enhance Quality of Life

Statement of Purpose re: Request the closing of Hunt June 20th Dear Mayor and Councilmembers,
My name is Wayne Armstrong and my partner Marcus, and I would like to close Hunt Avenue June 20th to bring pride celebrations to St.

Helena. There are pride events happening in Napa and Yountville and in the 31 years we have operated our businesses on Main Street there have never been any pride specific events held in St. Helena.

We are interested in creating a community-based inclusive celebratory event with activities that will be fun for all ages and have been heartened by the broad base community and business support we have received to the idea and interest in participating.

We imagine the event to feel like a small harvest festival with local food vendors, craft and art, music and dancing, activities such as face painting, a photo booth as well as representation by various LGBTQ groups.

Hunt Avenue provides a festive, cozy, centralized space that will benefit local residents, visitors and downtown business owners.

Thank you,
Wayne

None.

STATEMENT OF THE
PURPOSE:

Authorize the road closure of Adams Street and Library
Lane, allow for mobile food vendors to park and operate on Library Lane, and allow for the possession of open
alcoholic beverages on the closed portions of the streets for the Rianda House Car Show.

FINANCIAL IMPACT: The financial impact is $1,625 resulting from the applicant submittal of a Request for Fee Waiver form for 6 permits related to this event including an encroachment permit, a banner permit, a road closure permit, and a raw water
permit.

CEQA DETERMINATION: Not a CEQA Project (CEQA Guidelines §15378) BACKGROUND:

The Riand House Car Show is presented by the Gunilda Rianda Senior Center Association ("Rianda House") for the purposes of raising awareness of the needs of older adults in the community and raising funds to support Rianda House's programs and services.

The event will require a temporary closure of Adams Street east of 1001 Adams Street

Page 22 of 72 ends

to the dead end, and Library Lane. The closure will occur from 6:00a.m. to 6:00p.m. on Sunday, June 21, 2026, with the event itself expected to take place from 10:00a.m. to 4:00p.m. The closure will allow for the event, which is planned to display 75+ classic cars and vintages trucks, as well as set-up and clean-up of the event. Additionally, it will allow for mobile food vendors to operate on Library Lane during the event.

DISCUSSION:

Rianda House is taking the lead on communicating and coordinating with all residences and businesses within a 1,000-foot radius of the road closure, per the conditions of the road closure form, and will coordinate to ensure alternate access for any commercial driveways affected by the closure.

There will be a barricade equivalent to k-rail that will prevent errant vehicles driving through the closed portions of Adams Street for the actual event. The entrance fee has not yet been determined. Rented restrooms and trash cans will be placed in the closed portions of the street, and mobile food vendors will operate on Library Lane, which may include vendors selling alcohol. Rianda House is responsible for coordinating with their vendors to secure the necessary ABC licensing for the sale of alcohol at this event.

Vehicles in the car show will be lined up along the closed portion of Adams Street.

Members of the Rianda House teams have secured sponsors from local businesses and are advertising the show.

The event organizers will continue to coordinate and update City Staff members form the Police and Public Works Departments, and will follow through with any additional requirements that staff may have for the actual event.

Page 25 of 72 ends

RECOMMENDED
ACTION:

Receive and file.

PREVIOUS COUNCIL
ACTION:

Monthly receive and file reports to City Council.

STATEMENT OF THE
PURPOSE:

To provide monthly updates of the amount of water
produced at the Louis Stralla Water Treatment Plant and the Stonebridge Water Wells, and potable water delivered from the City of Napa.

FINANCIAL IMPACT: None.

CEQA DETERMINATION: Not a CEQA Project (CEQA Guidelines §15378) BACKGROUND:

The City of St. Helena publishes a monthly water report on the City website (https://www.cityofsthelena.gov/330/W). The report includes the amount of water produced at the Louis Stralla Water Treatment Plant and the Stonebridge Potable Water Wells, as well as potable water delivered from the City of Napa. In addition to presenting data on the amount of water delivered monthly, the report includes year-to-date information and prior year data. Water elevation and capacity at the Bell Canyon Reservoir is included, as well as information on rainfall and monthly weather temperatures.

DISCUSSION:

City staff has developed a forecasting tool to facilitate its ability to optimize water use and track water availability. Included as an attachment is the Monthly Water Report for March 2026. The water produced for March 2026 is up by 7% when compared to March 2025, and is down by 4% compared to the average of March 2018-2020. The chart below summarizes the water produced per source:

Bell Canyon Reservoir
The City is not in water emergency conditions based upon Phase 1 Water Emergency measures being terminated by City Council through adoption of Resolution No. 2023-94 on July 25, 2023. Bell Canyon Reservoir has adequate water to support the City's needs through this calendar year. The storage in the Bell Canyon graph (Attachment 2) has been revised to include historic reservoir supply levels since July 2021. It also shows the water availability forecast through June 2027 based on the highest water usage during a non-drought year (FY 19/20) and 10 inches of rainfall (lowest recorded).

As of April 1, 2026, Bell Canyon Reservoir elevation was at 420.87 feet, representing approximately 2,298.03 acre-feet (AF) and 96.4% capacity. Bell Canyon spillway level is 422 feet, representing 2,383.69 AF in water supply volume. Below is a chart comparing Bell Canyon Elevation levels, water supply availability in acre feet, and percent capacity of the reservoir on April 1 in 2024, 2025, and 2026:

Year 2024 2025 2026

As a follow-up to the May 24, 2022, City Council meeting, staff developed a graph (Attachment 3) highlighting the relationship between the reservoir elevation level and water supply availability in acre-feet. The graph shows the current status of the reservoir. Furthermore, the graph also displays the points where City Council decided to declare Phase I and Phase II Water Emergencies in 2020.

Page 27 of 72 ends

Continued Water Conservation
California experienced two consecutive dry years: 2020 and 2021. Due to the combination of warmer-than-average temperatures and minimal precipitation in the state, the Department of Water Resources (DWR) declared 2021 as the fourth-driest year on record statewide. The record-breaking dry period in January and February 2022, and the absence of significant rains in March 2022, required DWR to reduce anticipated deliveries from the State Water Project (SWP). However, the reduction at the time did not affect St. Helena as the City has multiple robust water sources not affected by the executive order. Water availability from the Bell Canyon reservoir is based on the City's State Water Rights permit and not the SWP. The City has not received any curtailment order from DWR nor does the City anticipate receiving one.

It should be noted that on July 25, 2023, the City Council adopted Resolution No. 2023- 94 to formally end the Phase I Water Emergency. The projected demand on the system versus the anticipated rainfall over the next year reflects an available supply in Bell Canyon of approximately 1,895 AF, significantly above the 1,481 AF standard for declaration of a Phase I Water Emergency. Staff will monitor statewide and local drought conditions, weather conditions, and provide updates on a monthly basis. The corresponding staff report provided a variety of data to reflect the disposition of the water supply at that time in relation to the Council-adopted Safe Yield Policy.

City of Napa Water Supply
Normal operations continue at Rutherford Pump Station and the City is taking delivery of the allotment purchased from the City of Napa. During the month of March 2026, Rutherford Pump Station produced an average of 0.54 MG/day of water, for a total of

52.10 acre-feet for the month.

Agendas Report to the City Council
Agenda Section: CONSENT ITEMS
Department: Public Works Department
DATE: April 28, 2026
FROM: Eric Janzen, Asst. PW Director
SUBJECT: Consideration and approval of a Public Utility Easement Deed between the City of St. Helena and PG&E and
authorization to record the Easement Deed with the County of Napa.

RECOMMENDED
ACTION:

Staff recommends City Council approve the attached
Resolution and approve the Public Utility Easement Deed between PG&E and the City of St. Helena.

PREVIOUS COUNCIL
ACTION:

None.

STATEMENT OF THE
PURPOSE:

Approve the Public Utility Easement Deed pursuant to
which the City of St. Helena grants a public utility easement to PG&E and authorize recording with the County of Napa Recorder's Office.

FINANCIAL IMPACT: None
CEQA DETERMINATION: Not a CEQA Project (CEQA Guidelines §15378) BACKGROUND:

PG&E wishes to relocate existing overhead electrical utilities underground. Some of these utilities cross land owned by the City of St. Helena. PG&E has requested easements from the City for these proposed underground utilities.

Existing overhead electrical infrastructure is located on the City owned parcels APN 021-420-005, APN 021-410-012 and APN 021-420-006, commonly known as the Louis Stralla Water Treatment Plant (WTP). PG&E wishes to relocate their existing overhead facilities underground. The underground facilities will closely parallel the existing overhead facilities and be of similar width and length. The underground easement will include a new transformer to be located near the existing WTP pump station. The transformer will be positioned such that it does not interfere with access, operation and maintenance of the pump station. All easements discussed herein are located along the private access road serving the WTP and Foley Family Wines (DBA Merus Wines) and are adjacent to Crystal Springs Road.

Page 34 of 72 ends

DISCUSSION:

PG&E and the City of St. Helena desire to approve and record a Public Utility Easement Deed (the "Easement Deed") pursuant to which the City will grant a public utility easement to PG&E. The Easement Deed authorizes PG&E to access the City's WTP properties in order to install, repair, maintain, operate, and replace their facilities. The easement deed also authorizes PG&E to perform periodic vegetation management, including tree removal, within the easement boundaries.

PG&E agrees to ensure that City Staff are able to access the WTP during construction or maintenance activities. PG&E further agrees to restore the surface of the ground to its prior condition following any of their construction or maintenance activities. PG&E will send notification to City Staff for scheduled maintenance activities and the City agrees to allow emergency activities to be performed without notification. Emergency activities will still be subject to the provisions of City Staff access to the WTP.

In accepting the easement agreement, the City agrees to allow PG&E access to their facilities. The City further agrees to not construct permanent facilities that would obstruct the easement or new underground facilities.

City Staff has reviewed the Public Utility Easement Deed and find it to be satisfactory and beneficial to both the City of St. Helena and PG&E. The City Attorney has also reviewed the Public Utility Easement Deed and finds it to be acceptable.

None.

any and all thereof, as Grantee deems necessary for the distribution of electric energy and communication purposes, that are necessary for Grantee to communicate with Grantee's facilities and no other purpose located within the strips of land, the centerlines of which are described in EXHIBIT “A”, EXHIBIT “C”, and EXHIBIT “E”, and depicted on EXHIBIT “B”, EXHIBIT “D”, and EXHIBIT “F” attached hereto and made a part hereof. .

Grantor further grants to Grantee the right, from time to time, to trim or to cut down, without Grantee paying compensation, any and all trees and brush now or hereafter within said easement areas.

Grantor also grants to Grantee the right to use such portion of said lands contiguous to said easement areas as may be reasonably necessary in connection with the excavation, construction, reconstruction, replacement, removal, maintenance and inspection of said facilities.

Grantor also grants to Grantee the right to excavate, grade, and level the ground, including the right to construct, reconstruct, replace (of initial size or any other size), remove, maintain, and inspect walls to maintain the graded slopes for the protection of Grantee’s public utility facilities located within the easement areas, together with the right to construct and maintain drainage facilities and other appurtenances in connection with the walls.

Upon the completion of any construction activities within said easement area, Grantee shall restore the surface, including paving, vegetation and other improvements to as near as practicable to the condition that existed prior to such construction.

Grantor reserves all rights to use the easement area (above and below ground) for any and all purposes, as long as those rights do not unreasonably interfere with Grantee’s herein granted express rights.

The legal description herein, or the map attached hereto, defining the location of this utility distribution easement, was prepared by Grantee pursuant to Section 8730 (c) of the Business and Professions Code.

Grantee understands that access to the Grantor’s facility is paramount at all times due to its critical facility status. If, due to Grantee’s future maintenance or replacement activities, Grantor’s operations or access is limited, Grantee shall ensure that any limited access for Grantor to Grantor’s facilities is limited in type and time to all that is absolutely necessary for the completion of Grantee’s work, for example in emergency maintenance or replacement situations.

This document may be executed in multiple counterparts, each of which shall be deemed an original, but all of which, together, shall constitute one and the same instrument.

Agendas Report to the City Council
Agenda Section: NEW BUSINESS
Department: Public Works Department
DATE: April 28, 2026
FROM: Bruce Zaeni, Project Manager
SUBJECT: Receive and File Water Treatment Plant Condition Assessment

RECOMMENDED
ACTION:

Receive and file the report.

PREVIOUS COUNCIL
ACTION:

Resolution 2023-146, adopted on November 14, 2023,
authorized the execution of a Professional Services
Agreement with West Yost for an amount not-to-exceed
$267,428 for engineering services to conduct a condition assessment of the Louis Stralla Water Treatment Plant for CIP Project W18-111.

STATEMENT OF THE
PURPOSE:

To receive and file the Water Treatment Plant Condition Assessment Report dated June 6, 2025.

FINANCIAL IMPACT: The action does not have a fiscal impact. The recommendations from the report will be incorporated into subsequent capital and operating budgets.

CEQA DETERMINATION: Not a CEQA Project (CEQA Guidelines §15378) BACKGROUND:

The purpose of this report is to present the results of an assessment of the Louis Stralla Water Treatment Plant (LSWTP). The LSWTP is located at 410 Crystal Springs Road and is owned and operated by the City of St. Helena (City). Over the last ten years, LSWTP has provided between 1/4 to 1/3 of the total water supply to the City. As a critically essential facility, staff was concerned about the LSWTP facility, namely the age and condition of various systems, processes, and equipment due to years of perceived deferred maintenance. In 2023, the City Council authorized execution of a professional services agreement with West Yost Associates to assess the LSWTP's current condition, operational requirements, and associated risk levels. In the near term, the City was interested in identifying prioritized condition and operations-related improvements and to improve operational reliability and simplicity during the next 5 to 15 years, assuming a small number of operators working at the LSWTP. The longerterm plan for the LSWTP would be examined as part of a separate, future study.

Page 51 of 72 ends

The scope of the consultant contract included the following:
• Project management and coordination
• Data collection and review of historical documents, schematics, operating records, and interviews with staff.
• Conduct a condition and risk assessment of the LSWTP assets and remaining useful life analysis.
• Develop recommendations for optimizing operations of the LSWTP with limited staff and with challenging water quality conditions
• Identify any age-related deficiencies among the control system hardware and software components.
• Develop a report for improvements related to CIP and Operations and Maintenance. The resulting report will summarize evaluations, findings, and document recommendations.

The City's primary objectives in preparing this report are summarized as follows:
• Assess existing WTP's current condition, operational requirements, and associated risk levels.
• Identify prioritized condition and operations-related improvements to improve operational reliability and simplicity, including the LSWTP's automation capabilities, during the next 5-15 years.
• Identify alternative means and methods that might be implemented to enhance water quality and/or result in a simpler, more modern treatment process.

The major topics addressed in this report include:
• Summary of Existing Facilities
• Water Quality Characterization and Performance Assessment • On-Site Condition Assessment
• Risk Assessment
• Recommended Capital Improvement Projects
DISCUSSION:

As stated above the infrastructure of the LSWTP is aging. Recent issues regarding water discoloration have brought into question the condition and the lifespan of the facility. The production of compliant, reliable, and quality water is an obligation, and this study will allow us to identify and plan for necessary upgrades to service to maintain all three.

This Executive Summary report prepared by West Yost Associates provides an overall view of the risks and lays out a methodical approach to categories of improvements to

Page 52 of 72 ends

consider. The recommended improvements are grouped into three categories including:
• Immediate term
• Near-term
• Long-term
Major Findings

1. General Plant Condition
The facility is in good to fair overall condition, with core treatment processes continuing to meet operational needs.

A significant portion of the plant’s mechanical and electrical equipment is 30–45 years old and has exceeded its expected service life.

Continued reliance on aging components increases the risk of unplanned outages and higher maintenance costs.

2. Electrical and Mechanical Systems
Several motor control centers (MCCs), pumps, mixers, and valves are original to the 1979–1994 construction era.

Many components require frequent reconditioning and are no longer supported by manufacturers.

Replacement of MCC-2M and MCC-1M is identified as a priority to maintain operational reliability.

3. Chemical Storage and Safety
Existing chemical tanks, containment areas, and piping systems show deterioration and corrosion.

Improvements are needed to meet current best practices for:
-Secondary containment
-Chemical segregation
-Worker safety and access
Upgrades will reduce risk of spills, cross-contamination, and regulatory non-compliance.

4. Controls, SCADA, and Cybersecurity
The plant’s SCADA servers (i.e. prior to server upgrades authorized in November 2025), network switches, and control hardware are obsolete and unsupported.

Limited integration of process equipment into SCADA reduces monitoring and automation capabilities.

Cybersecurity vulnerabilities require near-term attention to align with modern standards and protect critical infrastructure.

5. Structural and Seismic Considerations
Structural review identified seismic deficiencies, including roof-to-wall anchorage issues in the control building and chemical facilities.

Improvements are recommended to enhance resilience during seismic events and ensure safe access for operators.

Page 53 of 72 ends

6. Treatment Performance
Total Organic Carbon (TOC) removal generally meets regulatory requirements.

Turbidity performance is inconsistent, with occasional exceedances of optimization targets.

Periodic disinfection byproduct (DBP) exceedances in the distribution system indicate the need for:
-Improved treatment consistency
-Potential upgrades to treated water storage mixing and ventilation systems

7. Asset Risk Assessment
The assessment evaluated 229 individual assets for the likelihood and consequence of failure.

Approximately 50% of assets fall into the Medium Risk category.

Six assets are classified as High Risk, primarily electrical and control systems critical to plant operations.

Highest-risk process areas include filtration, chemical addition, flocculation/sedimentation, treated water storage, and the high-lift pump station.

Recommended Capital Improvements
Immediate (0–5 Years):

Plantwide SCADA modernization and cybersecurity upgrades Pretreatment and filtration optimization studies
Replacement of MCC-2M and critical valve operators
Evaluation and upgrades to treated water tank mixing and ventilation Near-Term (6–10 Years)
Replacement of MCC-1M
Structural/seismic improvements to control and reservoir outlet facilities Chemical storage and piping rehabilitation
Replacement of aging pretreatment equipment (flocculators, mixers, sludge collectors) Corrosion control and coating improvements
Evaluation of returning Tank 1 to service
Long-Term (11–15 Years)
Rehabilitation of the original Bell Canyon chemical building Improvements to flash mix vault access and mechanical systems Replacement of backwash pumps, high-lift pumps, and MCC-3M Miscellaneous improvements to clearwell, washwater, and sludge lagoon systems Estimated Capital Cost
Timeframe Estimated Cost (Future Dollars)
Immediate (0–5 years) $1.8 million
Near-Term (6–10 years) $4.7 million
Long-Term (11–15 years) $2.7 million

Page 54 of 72 ends

Total (15-year horizon) $9.2 million
Cost estimates assume 2% annual inflation to mid-construction period.

The assessment confirms that while the LSWTP continues to meet current operational needs, several critical systems are at or beyond their useful life. A phased capital improvement program will allow the City to address the most urgent deficiencies, reduce operational risk, and ensure long-term regulatory compliance and service reliability.

It should be noted that the full and detailed report can be made available to City Council members in private, if requested. However, for homeland security reasons, we are not sharing the sensitive city water system and service reliability.

On February 12, 2026, the Executive Summary was presented to the Water and Wastewater Adivsory Committee. While members of the Committee lamented on the absence of the full report for the discussion, staff provided the opportunity for members to view the report through an in-person appointment. All five regular members of the Committee voted to recommend the report be taken to City Council for consideration.

KEY CONDITION ASSESSMENT FINDINGS
The following summarizes key findings from the condition assessment of the LSWTP’s structures, equipment, instrumentation, and software systems:
 General Condition: The LSWTP is in overall good to fair condition, with most structures sound and many process units still performing adequately. However, much of the plant’s equipment is over 30 years old and beyond its anticipated useful life.  Aging Electrical and Mechanical Equipment: Several original motor control centers (MCCs), pumps, mixers, and valves have exceeded service life. Continued operation is possible only through periodic reconditioning. This approach is not sustainable long-term.  Chemical Storage and Safety: Many original chemical storage tanks and associated piping are deteriorated. Improvements are needed to ensure safe handling, secondary containment, and segregation of incompatible chemicals.  Controls and Automation: Outdated SCADA servers, network switches, and control hardware are no longer supported by manufacturers and are vulnerable to cybersecurity risks. Integration of equipment into SCADA would improve monitoring, control, and efficiency.
 Resilience and Safety: Seismic assessments found deficiencies in several structures, including roof-to-wall anchorage in control and chemical buildings. Improvements will be needed to enhance worker safety and ensure reliable operation during seismic events.

Additionally, the following summarizes recent historical water quality performance of the LSWTP:
 Total Organic Carbon (TOC) removal generally exceeds regulatory requirements.  Turbidity data show inconsistencies and periodic exceedances of optimization goals, highlighting the need for pretreatment and filter optimization.  Distribution system monitoring has identified occasional exceedances of disinfection byproduct (DBP) standards, underscoring the need for improved treatment consistency and potential distribution system tank mixing and/or ventilation upgrades.

RISK ASSESSMENT RESULTS
A structured risk assessment was performed considering likelihood of failure (LOF) and consequence of failure (COF) for each asset and process area.
 Nearly half of the 229 plant assets assessed fall into the “Medium Risk” category.  Six assets (≈3%) are rated as “High Risk”, primarily electrical and control systems where failure would immediately impact treatment operations.
 Process areas with the highest overall risk include filtration, chemical addition, flocculation/sedimentation, treated water storage, and the plant’s high lift pump station.

A visual representation of asset risk by process area is shown in Figure 2. The risk assessment prioritization informed the capital improvement recommendations to ensure the most critical vulnerabilities are addressed first.

ESTIMATED INVESTMENT NEEDS
The total estimated cost to implement the recommended improvements over a 15-year horizon is approximately $9.2 million, as summarized in Table 1:

Table 1. Summary of Estimated Costs for Recommended Improvements Improvement Time Frame Estimated Cost, Future Dollars(a) Immediate-Term (0-5 years) $1.8 million
Near-Term (6-10 years) $4.7 million
Long-Term (11-15 years) $2.7 million
TOTAL $9.2 million
(a) Assumes 2.0 percent annual inflation through the estimated midpoint of construction.

These figures reflect planning-level total capital cost estimates and may vary with inflation, implementation timing, bidding conditions, and other project-specific factors.

FINAL SUMMARY
The overall assessment results and LSWTP prognosis can be summarized as follows:
 The LSWTP is generally sound but contains a significant amount of aging infrastructure that must be proactively addressed.
 Investments are required to modernize electrical and control systems, upgrade chemical storage and safety, and replace critical treatment equipment.  Optimization studies should be undertaken early to fine-tune pretreatment and filtration performance and reduce DBP risks.
 A phased capital improvement program will spread costs over time while focusing first on the highest-risk items, ensuring continued reliability, safety, and regulatory compliance for the City’s surface water treatment facility.
 Together, these investments will help protect St. Helena’s drinking water supply for decades to come.
