1. CAPITAL IMPROVEMENT PROGRAM DESCRIPTION
The San Francisco Public Utilities Commission (SFPUC) Water Enterprise manages a complex water supply system stretching from the Sierra Nevada to San Francisco and featuring a series of reservoirs, tunnels, pipelines, and treatment systems. Two unique features of this system stand out: the drinking water provided is among the highest quality in the world, and water deliveries are made to most customers without the use of power, by gravity flow, while generating power at the same time.

The SFPUC is the third largest municipal utility in California, serving 2.7 million residential, commercial, and industrial customers in the Bay Area. Approximately one-third of the delivered water goes to retail customers in San Francisco, while wholesale deliveries to 26 suburban agencies in Alameda, Santa Clara, and San Mateo counties comprise the other two-thirds.

The Regional Water System consists of water storage and treatment facilities; water transmission infrastructure; buildings and structures for fa cilities and employees; communications systems; and watersheds and Rights-of- Way (ROW) lands in San Mateo, Santa Clara, and Alameda Counties as well as western San Joaquin County. The Regional Water System also includes numerous assets in San Francisco that are operated in conjunction with the regional system. The Regional Water System Capital Improvement Program (Regional Water CIP) part of the SFPUC’s Ten Year Capital Improvement Program (10-Year CIP), is a 10-year proposed appropriations plan including planned projects to physically improve the assets within the Regional Water System. The 10-Year CIP is updated every two years (with minor modifications in the off years) and integrated with the SFPUC’s Financial Plan and rate-setting.

Biannual updates to the Regional Water CIP also account for post-Water System Improvement Program (post-WSIP) conditions, including deferred projects not in WSIP and new projects needed to continue meeting level of service goals and to maintain facilities in a state of good repair.

The capital planning process is used to inform the Regional Water CIP with updates to master plans, asset condition assessment, and review of levels of service. There are six (6) groupings of projects in the Regional Water CIP. The categories are:
• Water Treatment
• Water Transmission
• Water Supply and Storage
•
Watershed and Lands Management
• Communications and Monitoring
•
Buildings and Grounds
A
project is formally initia
ted (Project Initiation) when the planning process begins, a project manager is assigned, and the project’s initial Approved Budget consistent with the most recently adopted Regional Water CIP is established.

Projects move from the planning, design, and environmental review phase to contract-award and construction phase when Project Approval occurs through an action by the Commission, usually at the same time CEQA findings are adopted. The Commission may also make decisions about a project’s scope, budget, or schedule during annual or bi-annual review and approval of the Regional Water CIP. 1 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 – 06/30/23) While a project is active, additional budget modifications outside of the annual or bi-annual CIP process require approval of the Assistant General Manager (AGM) for the Water Enterprise. When and if these budget modifications occur, the modified budget becomes the new Approved Project Budget.

Outside of formal budget adjustments, the project manager regularly estimates and records the anticipated final project cost and schedule as the Forecasted Cost and Forecasted Schedule. Minor modifications to scope or schedule must be approved by increasing levels of management, with major modifications requiring approval by the Program Director and AGMs of Infrastructure and Water Enterprise. Most scope, schedule, and budget changes must be pre-approved by the Change Control Board which consists of managers within the Water Enterprise and Infrastructure Division. Final Project Closeout must be approved by the AGMs for Infrastructure and Water Enterprise.

Changes to the approved baseline program, including any changes to continuing projects’ scopes, schedules, and budgets, are proposed as part of the biannually updated 10- year CIP to be approved by the SFPUC Commission. The proposed revisions to the program become the new baseline for new and continuing projects’ scopes, schedules, and budgets in the beginning of the new fiscal year following SFPUC Commission approval.

2. CAPITAL IMPROVEMENT PROGRAM STATUS
This Quarterly Report presents the progress made on Regional Water projects between April 1, 2023 and June 30, 2023. This document serves as the fourth (4th) Quarterly Report in Fiscal Year 2022- 2023 (FY23) published for the Water Enterprise Capital Improvement Program.

This quarterly report incorporates all the changes made to the Regional Water Enterprise CIP projects and the Local Water Enterprise CIP projects in the Water Enterprise Capital Improvement Program according to the 10-Year Capital Plan for FY2022-23 to FY2031-32, presented to and adopted by the Commission on February 8, 2022, under Resolution No. 22-0031. The 10-Year Capital Plan for FY2022-23 to FY2031-32 serves as the new baseline for project scopes, schedules, and budgets starting as of the first quarter (Q1) of FY2022-23. The 2022 Approved Water Enterprise CIP is a subset of the Regional and Local Water Enterprise 10-year CIP for FY2023-2032 and includes individual projects over $5 million that were then currently active or intended to be active by June 30, 2022 at the time proposed to the Commission on February 8, 2022.

The 2022 Approved Regional Water Enterprise CIP (2022 Regional WECIP) has twenty-five (25) projects. The only Regional project not yet initiated and therefore not reported on herein is Merced Manor Reservoir Facilities Repairs; a project description is included in Appendix A. 2 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 – 06/30/23) Figure 2.1 shows the total Current Approved Budget for the 25 Regional projects in each phase of the program as of June 30, 2023.

7. PROJECT STATUS REPORT
10033123 - SVWTP Ozone (CUW27202)
Project Description: In recent years, SFPUC’s Sunol
Valley Water Treatment Plant (SVWTP) has experienced more frequent taste and odor (T&O) events from seasonal algal blooms than had occurred historically. This project’s objective is to install ozone treatment facilities as a long-term solution to control T&O events encountered in the raw water supply from both the San Antonio and Calaveras Reservoir sources. This project will improve the reliability to meet water quality goals especially during warm months and during Hetch Hetchy shutdowns.

Progress and Status:

During the reporting period, the 100% design package was further developed to address stakeholder comments. The
notice of upcoming advertisement was posted to SFPUC’s
bidding site, and an advertisement was in development for inclusion in the August issue of Engineering News-Record.

An amendment to the SVWTP Expansion and Treated Water
Reservoir Environmental Impact Report continued to be
developed to cover work under this project.

Issues and Challenges:

The budget variance is due to further design developments, an updated construction cost estimate, and increased project delivery costs, including both construction management and design support services. The schedule variance is due to additional duration forecast for the Construction phase due to further design developments and additional time forecast for the Bid and Award phase to mitigate anticipated risks.

15 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 - 06/30/23) 10015064 - SVWTP Short Term Improvements
Project Description: The primary objective of the
SVWTP Short Term Improvements project is to improve regional delivery reliability by addressing various conditions and deficiencies of the Sunol Valley Water Treatment Plant (SVWTP). Upgrades were identified through condition assessments and operations staff observations, review of level of service, subsequent feasibility studies, and alternative analyses.

Progress and Status:

During the reporting period the 95% design package was
issued to stakeholders for review. The reviewers’ comments were collected and are being reviewed for incorporation into the 100% design. Development of the 95% construction cost estimate continued.

Issues and Challenges:

The Short-Term Improvements project scope has been
revised to include nine critical scope items to address plant reliability issues identified by Water Supply and Treatment Division. The budget variance is due to construction and project delivery cost increases since the draft Conceptual Engineering Report. The schedule variance is due to longer Conceptual Engineering Report and design phase durations needed to sequence and detail the requirements for the
additional nine scope items. A longer construction duration is also anticipated due to the changes in scope, extended
anticipated construction material lead times, and need to coordinate construction within the limited time frames of facility outages.

Existing Leaks at Expansion Joints
16 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 - 06/30/23) 10037628 - SVWTP Polymer Feed Facility
Project Description: At the Sunol Valley Water
Treatment Plant (SVWTP), the new flocculation/sedimentation basin built in 2013 as well as the other 4 existing basins that are each rated at a capacity of 40 million gallons per day (mgd) were not able to achieve their capacity under all operating and water quality scenarios. A basin optimization plan was prepared to address the performance; it recommended adding a flocculant aid polymer system. The project will build a polymer feed facility that will serve all five sedimentation basins to optimize plant water production.

Progress and Status:

During the reporting period, coordination continued for the future full-scale tests at Sunol Valley Water Treatment Plant to confirm the need and design criteria for polymer systems in the five sedimentation basins. The project team continued coordination on securing the polymer testing equipment.

Issues and Challenges:

The schedule variance is due to the need to perform
additional full scale plant testing to verify performance assumptions. The full-scale testing is planned to begin in Summer 2023. After testing is complete, any needed scope refinements will be identified, confirmed, and implemented through this project. The budget variance is due to adoption of the preferred cost savings option identified from the 65% cost estimate.

18 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 - 06/30/23) 10037350 - Regional Groundwater Treatment Improvement
Project Description: The purpose of this project
is to improve the performance of the Regional Groundwater Wells and treatment systems in the South Westside Basin for reliable use during dry years. In normal and wet years, the SFPUC will supply treated surface water to Daly City, San Bruno, and Cal Water to be used in place of their typical groundwater supply, thereby increasing the volume of groundwater in storage that can be pumped as supplemental water in dry years. This project will address emerging well water quality issues that require treatment, will provide additional reliability for treatment systems at the wells, and will evaluate the potential for a consolidated treatment facility (through Alternatives Analysis only).

If a centralized treatment alternative is selected, the estimated project cost could potentially be $250 million, which includes construction of approximately 14 miles of 8" to 24" diameter pipeline, a pump station, storage tanks, treatment facilities, and other ancillary facilities. This project will build auxiliary water treatment facilities as well as other enhancements to increase the reliability and efficiency for maintenance and operation of the well stations.

21 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 - 06/30/23) 10035029 - As-Needed Pipeline Repairs
Project Description: Water Supply and Treatment Division's (WSTD) maintenance and inspection program inspects the
regional pipeline system on an ongoing basis. However, when repairs are identified to be needed following inspections and when emergency repairs are needed, a contractor is not readily available to perform the repairs. This project will increase system reliability by reducing the duration and number of outages since a prequalified, as-needed contractor will be available to complete repairs immediately following inspections or in emergencies. This project will repair/replace regional pipeline segments that will be inspected over the next five years, in addition to any emergency repairs that may be needed.

The initial construction contract will be 3 years and combined with Project 10036840, BDPL1-4 Lining Repair to provide a sufficient guaranteed scope. Subsequent construction contract(s) will be issued to parallel WSTD's inspection program.

Valve House where New Isolation Valve will be Installed 22 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 - 06/30/23) 10036839 - BDPL4 PCCP Repair
Project Description: Historically, when pre-stressed concrete cylinder pipe (PCCP) fails due to breaks in the spirally
wound wire, the high-pressure failure can have catastrophic consequences. Some segments of the Regional Water System are constructed of PCCP. From recent inspections of Bay Division Pipeline No. 4 (BDPL4) Segment D, constructed of PCCP, a large number of wire breaks and circumferential cracks were found in the last 1.25 miles of pipeline that parallels Edgewood Road in Redwood City. In addition, several leaks have surfaced at circumferential cracks and where the pipeline transitions from PCCP to steel. Segments where wire breaks are concentrated will need to be repaired/replaced to prevent catastrophic failure and circumferential cracks and leaks will also be repaired. The first phase of this project will be to repair segments where there are high concentrations of wire breaks, wide circumferential cracks and active leaks. This first phase will include planning, design and construction of repairs. The second phase of the project will be to address the remaining

1.25 miles of pipeline, which includes planning, design and partial encumbrance of a construction contract. The project budget will be reevaluated following completion of the Alternatives Analysis for the second phase. The first construction contract will increase system reliability by rehabilitating approximately 650 feet of 84-inch diameter BDPL4 PCCP in Redwood City.

During the reporting period, the
project team issued the
construction contract advertisement, performed contractor outreach, and conducted the pre-bid meeting. The project team also responded to questions on the bid documents.

Issues and Challenges:

As reported in the last quarter, the overall schedule variance is due to the additional 14 months required to complete permit requirements under the National Environmental
Protection Act in order to be eligible for a grant administered by CalTrans. The overall budget variance is due to new
environmental requirements causing increased construction cost and delays to construction contract advertisement
leading to increased escalation costs.

Progress and Status:

For this reporting period, the
project achieved the 100%
Design milestone and moved into Bid and Award phase.

During 95% design, the geotechnical design was reviewed by a third-party expert consultant, who recommended
modifications to the design incorporating deeper soldier piles During the quarter, 100% design was prepared including
changes to the soldier pile design. The 100% cost estimate was prepared including cost increases for the geotechnical changes as well as increased soft costs due to the longer construction duration. A third-party estimator validated the 100% construction cost estimate reached by the design team.

Also, during the quarter, a notification letter was sent to the San Francisco Planning Department for concurrence
regarding modification to the existing Peninsula Watershed Environmental Impact Report. Multiple environmental permit applications were sent to State and Federal agencies. The forecast to obtain environmental clearance is by the end of December 2023. This construction contract is anticipated to be advertised in August 2023, with award of the contract pending environmental clearance.

Issues and Challenges:

The forecasted cost increased during the quarter due to additional geotechnical improvements and the updated 100% cost estimate including increased costs for the longer
construction duration. The previous cost variance was from the addition of a debris boom and anchorage system within the reservoir, and the savings from deleted scope of roadway realignment. The schedule variance is to accommodate time to lower the water level in the reservoir and for additional time anticipated to obtain environmental clearance for the changed scope.

Progress and Status:

Contract A) Warehouse Settlement; Completed.
(Contract B)
Administration Building HVAC Upgrades (JOC): The scope of work consists of the retrofit of the existing heating, ventilation, and air conditioning (HVAC) system inside the building rather than replacement of the HVAC system in a location external to the building. Additional scope of work has been identified, which consists of upgrade to the existing pneumatic controls to electronic controls and refurbishment of the existing fans to allow the HVAC system to be more reliable. This is essential to be performed prior to performing other repairs or
replacements such as individual zone temperature control. A Job Order Contract (JOC) task order has been initiated, and a contractor has been assigned.

Issues and Challenges:

The budget and schedule variances are due to the reduction of the scope of work. The scope of this project in the
previously approved Water Enterprise CIP consisted of
removal of the outdated main heating, ventilation, and air conditioning units, and placement of the main components of the new HVAC system outside of the building. The delay is due to time needed to add a subcontractor with experience to perform the work, since neither the prime nor the current subcontractors have the necessary experience. The
subcontractor will have five (5) years of experience in the installation and refurbishment of HVAC equipment and
Automated Logic Building Management System and possess
a C-20 license. The subcontractor will also have experience working at SFPUC facilities.

34 I. Regional WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 - 06/30/23) 10015124 - Sunol Long Term Improvements
Project Description: The project includes redevelopment of the existing Sunol Yard and construction of a Watershed Center near the Sunol Water Temple. Most of the existing structures at the Sunol Yard date back to 1930 and were converted from the original purpose, residence and barn, to office and shop spaces. The structures contain lead-based paint, asbestos, bats, and bat guano, and did not meet current building, health, or safety codes. The project will demolish six existing dilapidated structures at the Sunol Yard and construct a LEED Gold administration building, shops, fuel station, backup generator system, truck wash station, paving and site restoration.

Progress and Status:

Sunol Yard (Contract A): Completed. Watershed Center
(Contract B): During the reporting period, negotiation on the substantial completion date, remaining construction items and deficiency list work continued. The public artwork was
completed. As reported last quarter, the berm along the building exterior settled due to the winter rains and damaged some of the utility pipelines. The inspection of these damaged utility pipelines was completed this quarter, and discussion on the repairs continued. The submittals and fabrication work continued for exhibits, furniture, fixtures, equipment, site signage, and bluestone etching.

Issues and Challenges:

The budget variance is due to delays related to exhibit redesign work, additional archaeological monitoring and recovery
work, costs of project delivery for additional owner-
requested scope, and other miscellaneous changes to the original construction contract. A sinkhole developed in the landscape area and may be related to an existing pipeline crossing through the site and connecting downstream to the Sunol filter galleries. Investigation of this pipeline’s status and condition is underway by Water Supply and Treatment
Division and is not part of the project.

10015128 - Millbrae Yard Laboratory and Shop Improvements Project Description: SFPUC has determined that
the existing Millbrae Administration Building must remain operational following a major earthquake, and therefore needs to be retrofitted or replaced to meet essential facility requirements.

SFPUC also wants to expand the existing Millbrae Administration Building to merge and house the Water Enterprise staff and equipment from the Rollins Road Facility. This project is necessary to provide Water Enterprise personnel a long term and sustainable campus, and allow the consolidation of work groups for increased staff efficiency. This project will also alleviate shortage of program space, increase efficiency of operations, improve employee working environment with improved heating, ventilation, and air conditioning, improve employee health and safety, and enhance site and building security. A recent planning study has identified several alternatives to meet the project goals. The selected alternative for the Millbrae Yard campus improvements will be implemented in three phases. Phase 1 includes a new laboratory office and new south shop building to alleviate Water Enterprise undersized and outdated workspaces and desire to relocate mission- critical functions to code-compliant structures. This project will provide additional space in the laboratory building by constructing two additional floors on top of it to accommodate the relocation of all personnel from Rollins Road Facility.

Phase 2 includes demolition of the existing Administration Building and construction of a new consolidated Administration Building adjacent to the new laboratory building to accommodate other Water Enterprise staff. Phase 3 includes new covered storage for materials and equipment. Only the scope of work for Phase 1 will be implemented under this project to meet near-term needs, minimize disruptions to operations, and allow gradual buildout of the master plan to stay within the 10-year CIP budget.

Progress and Status:

The proposed revision to the
space planning scheme and the
corresponding high level cost estimate for a new proposed conceptual scheme were completed and are currently being reviewed. Preparation of the Request for Proposals (RFP) for engineering services through SF Public Works Contracts
group will resume after revision to the scope of work is finalized. The RFP focuses on the civil, structural,
mechanical, electrical, and plumbing services.

Issues and Challenges:

The schedule variance is due to the following: planned delay to the start of construction for budgetary reasons; increased project scope leading to increase in the forecast for both bid and award and construction phases; time needed to procure a consultant for engineering services; and additional time needed to complete planning phase to implement the new
conceptual scheme for the project. The budget variance is due to increased scope based on the alternatives planning study, including changes to the laboratory and administration buildings, south shop, tenant area, and exterior site.

1. CAPITAL IMPROVEMENT PROGRAM DESCRIPTION
The San Francisco Public Utilities Commission (SFPUC) Water Enterprise manages a complex water supply system stretching from the Sierra to San Francisco and featuring a series of reservoirs, tunnels, pipelines, and treatment systems. Two unique features of this system stand out: the drinking water provided is among the highest quality in the world, and water deliveries are made to most customers without the use of power, by gravity flow, while generating power at the same time.

The Local Water System is located primarily within the City and County of San Francisco and consists of water storage and treatment facilities; water transmission and distribution infrastructure; buildings and structures for facilities and employees; communica tions systems; and various lands in the City and County of San Francisco. In addition, the Local Water System includes several other small retail systems in Alameda, Santa Clara and San Mateo Counties where the SFPUC directly retails water to various customers. Groundwater in San Francisco is under the jurisdiction of the SFPUC; the Westside Basin is the only viable aquifer for municipal use. Additionally, the Local Water System includes the Emergency Firefighting Water System (EFWS) used for fire suppression in San Francisco and developer-funded assets that have been conveyed to the SFPUC.

The Local Water System Capital Improvement Program (Local Water CIP) is a 10-year proposed appropriations plan of scheduled projects to physically improve the system assets and maintain level of service goals. This Local Water CIP is updated every two years (with minor modifications in the off years) and integrated with the SFPUC’s 10-year Financial Plan and rate-setting.

There are seven (7) groupings of projects in the Local Water CIP in addition to a separate set of programmatic projects used for feasibility planning, for future capital projects, and for implementation of permit compliance activities. The categories are:
• Local Water Supply
• Local Water Conveyance/Distribution
• Local Reservoirs and Tanks Improvements
• Pump Station Improvements
•
Automated Water Meter Reading
• Buildings and Grounds Improvements
• Emergency Firefighting Water System
A project is f
ormally initiated
(Project Initiation) when the planning process begins, a project manager is assigned, and the project’s initial Approved Budget consistent with the most recently adopted Local Water CIP is established.

Projects move from the planning, design, and environmental review phase to contract-award and construction phase when Project Approval occurs through an action by the Commission, usually at the 1 II. Local WECIP Quarterly Report Q4-FY2022-2023 (04/01/23– 06/30/23) same time CEQA findings are adopted. The Commission may also make decisions about a project’s scope, budget, or schedule during annual review and approval of the Local Water CIP.

While a project is active, additional budget modifications outside of the annual CIP process require approval of the Assistant General Manager (AGM) for the Water Enterprise. When and if these budget modifications occur, the modified budget becomes the new Approved Project Budget.

Outside of formal budget adjustments, the project manager regularly estimates and records the anticipated final project cost and schedule as the Forecasted Cost and Forecasted Schedule.

Minor modifications to scope or schedule must be approved by increasing levels of management, with major modifications requiring approval by the Program Director and AGMs of Infrastructure and Water Enterprise. Most scope, schedule, and budget changes must be pre-approved by the Change Control Board which consists of managers within the Water Enterprise and Infrastructure Division. Final Project Closeout must be approved by the AGMs for Infrastructure and Water Enterprise.

Changes to the approved baseline program, including any changes to continuing projects’ scopes, schedules, and budgets, are proposed as part of the bi-annually updated 10- year CIP to be approved by the SFPUC Commission. The proposed revisions to the program become the new baseline for new and continuing projects’ scopes, schedules, and budgets in the beginning of the new fiscal year following SFPUC Commission approval.

2. CAPITAL IMPROVEMENT PROGRAM STATUS
This Quarterly Report presents the progress made on Local Water projects between April 1, 2023 and June 30, 2023. This document serves as the fourth (4th) Quarterly Report in Fiscal Year 2022-2023 (FY23) published for the Water Enterprise Capital Improvement Program.

The 2022 Approved Water Enterprise CIP is a subset of the Regional and Local Water Enterprise 10- year CIP for FY2023-2032 adopted by the Commission on February 08, 2022, under Resolution No. 22-0031, and includes individual projects over $5 million that were then currently active or int ended to be active by June 30, 2022 at the time approved by the Commission.

The 2022 Approved Local Water Enterprise CIP (2022 Loc al WECIP) has eleven (11) projects. No Local project is in “Not Initiated“ status
2 II. Local WECIP Quarterly Report Q4-FY2022-2023 (04/01/23– 06/30/23) Figure 2.1 shows the total Current Approved Budget for the Local projects in each phase of the program as of June 30, 2023. The number of projects currently active in each phase is shown in parentheses.

Figure 2.2 shows the number of Local projects in the following phases as of June 30, 2023: Pre- construction, Construction, and Post-construction.

Local WECIP Quarterly Report Q4-FY2022-2023 (04/01/23– 06/30/23) Figure 2.3 summarizes the environmental review status of the Local projects as of June 30, 2023.

The Local Water Conveyance/Distribution System Program has an annual goal to replace or improve a target of 15 miles of water mains in San Francisco. Figure 2.4 shows the planned and actual miles of pipeline projects that have reached substantial completion since FY19. The actual in-service mileage for FY23 is 9 miles which did not meet the target of 15 miles due to a reduction in program budget for FY22 and FY23.

4. CAPITAL IMPROVEMENT PROGRAM SCHEDULE SUMMARY
Figure 4 compares the 2022 Approved Schedule and the Current Forecast Schedule for the Local Water CIP. As shown in Table 4, the 2022 Approved and Forecast Schedule completion for the overall Water Enterprise CIP (including Regional and Local Programs) are each in June 2035. The 2022 Approved and Forecast Schedule completion for the Local CIP are in June 2032 and June 2033 respectively.

Table 4. 2022 Approved vs. Current Forecast Schedule Dates The reason for the schedule variance for the Local Water Program is due to the addition of one year of budget for the Local Water Conveyance/Distribution System project; this is a rolling capital project that has funding added annually.

10033816 - Potable Emergency Firefighting Water System
Project Description: This project provides funding for
the design and construction of about 2 to 3 miles of large diameter earthquake resistant pipeline to improve the fire water and potable supply reliability in the western area of San Francisco, particularly in the Sunset and Richmond Districts. This project is part of a larger effort to construct approximately 14 miles of the Potable Emergency Firefighting Water System (PEFWS), which also includes two planned pump stations. Current funding will fund the aforementioned 2 to 3 miles of pipeline and design work for a Lake Merced Pump Station. The pipeline will be designed as a potable AWSS pipeline, meaning it will convey low pressure potable water with connections to the distribution system during normal operations but can be isolated with motorized valves and operate under high pressure for firefighting after a major seismic event or emergency conditions by activating associated pumps. This funding will provide planning and design through FY 22-23 with construction funding in FY24 and 25. Additional funding will be provided by existing Earthquake Safety & Emergency Response (ESER) general obligation bond funds, with additional funding possibly approved in the March 2020 ESER referendum. The total Local Water funding commitment to this project is $55M with $12M carryover from FY 18-19 and FY19-20 budgets.

13 II. Local WECIP Quarterly Report Q4-FY2022-2023 (04/01/23 - 06/30/23) 10033818 - Town of Sunol Pipeline
Project Description: Since 2000 the SFPUC has
replaced the majority of the Town of Sunol pipeline system through the Town of Sunol Fire Suppression project, except for two segments. This project will complete the replacement of the last two segments of the system, by replacing sections of the pipeline that crosses the Arroyo de Laguna Creek (Creek Crossing) and under Highway 680.The upstream section of pipeline that feeds the Town of Sunol is exposed under the creek and in danger of failing under Highway 680. Pipeline failure at either location has significant consequences, since all fire and potable water in the Town of Sunol is dependent on the rehabilitation of this 12-inch diameter line. This project will reduce maintenance from pipe breaks and have less main flushing which may lower impact on operating expenses.

Progress and Status:

During this quarter, the project team
learned that the Caltrans
Arroyo De La Laguna Bridge Replacement project will be
performing construction within the same footprint in the creek as this project. Coordination between the two projects on the environmental mitigation will be required by the permitting agencies for such issues as dewatering the creek during construction and replanting of trees following construction.

Coordination between the project teams has started, but will lead to delay in advertisement of the construction contract while the teams determine how to coordinate efforts. The 95% package was being updated with coordination
information from the Caltrans project, and this update is anticipated to be completed next quarter.

Issues and Challenges:

The project schedule is anticipated to increase by an
additional year due to the additional coordination effort with Caltrans and environmental permitting. Although the
coordination would likely not require a full year’s delay, construction is constrained to the summer months since a portion of the work crosses the Sunol Glen School, which requires construction be performed only when school is not in session during summer break. The budget variance is
attributable both to additional escalation costs and to a newly added permit requirement that the existing Town of Sunol Pipeline be removed from the creek. Potential changes to budget and schedule forecasts will be reported in future reports.

Progress and Status:

This programmatic project includes multiple active and
upcoming construction contracts (refer to Section 8 for the active construction status). The actual length placed in service for the main replacement program in FY23 totals 9 miles. Projects under construction during Q4 FY23 included the streets of 19th Avenue, Vicente Street, Prospect Avenue, L-Taraval Segment B, Diamond Street, and Laidley Street. In addition, the Notice to Proceed for Hampshire Street project was issued on June 13.

Issues and Challenges:

The forecasted cost is less than the approved budget, and the forecasted completion date is later than the approved completion date, due to the programmatic project budget and schedule being revised for the FY24-33 10-Year CIP. The budget was reduced to meet funding availability, and the schedule was extended by one year since this is a rolling 10- year replacement program.

Grande Drainage Basin Improvement managed by Daly City; (B) Lake Merced Aeration Mixing System - Phase 1 (JOC
Contract); and (C) Lake Merced Recycled Water Diversion - Phase 3. Vista Grande Drainage Basin Improvement Project (Contract A): Daly City is currently working with staff at the California Coastal Commission to address concerns over
construction of an outflow structure at Fort Funston. Following completion of an initial appraisal in December 2022, SFPUC’s Real Estate Services (RES) is coordinating review of property that would be needed for the project. Lake Merced Recycled Water Diversion (Contract C): Preliminary design to divert recycled water from the new Westside Recycled Water Plant into Lake Merced to manage lake levels continued during the quarter. SFPUC staff completed a draft evaluation of project feasibility and are currently working on an alternatives analysis to evaluate design options and provide input to the 35% design documents.

Issues and Challenges:

SFPUC staff have evaluated potential changes to lake
resources as a result of updated diversion criteria being proposed by Daly City. Proposed changes will not result in any significant changes in estimated volumes of stormwater to be diverted into the Lake. The project schedule continues to be impacted by challenges with California Coastal
Commission permitting and with funding acquisition by Daly City. As part of Phase III, SFPUC staff are currently
evaluating options for delivery of recycled water to Lake Merced.

Progress and Status:

This project includes multiple construction contracts. (A) Recycled Water Treatment Facility; (B) Pump Station and Reservoir; (C) Pipeline; (D) Irrigation System Retrofits; (E) (proposed) Primary Power for Distribution Pump Station.

Treatment Facility (Contract A): The majority of construction work at the treatment facility is complete. Start-up testing was initially delayed to complete troubleshooting of the chemical feed
systems. Once testing was re-started, new issues were
discovered with the secondary effluent and reverse osmosis system pumps’ variable frequency drives (VFDs) which did not function properly during the testing, preventing pump operation. Start-up testing was therefore placed on- hold again. The VFDs are currently being evaluated by the
manufacturer. (Contract B): The start-up test plan was
approved, and testing commenced. Equipment functional
testing and 5-day testing were completed. In addition,
Contract B was determined to be eligible for retail PG&E service, so the project will submit a new application for power service directly with PG&E. The timeline for full energization has not yet been established. Pipeline (Contract C) is
complete. Irrigation System Retrofit (Contract D): Installation of Recycled Water signage in Golden Gate Park continued.

Punchlist walkthrough of the retrofit work continued. The Irrigation System Operations Plan and Standard Operating Procedures (for recycled water use) for Golden Gate Park was completed. The Notice of Applicability for Enrollment in the State Water Resources Control Board Water Reclamation Requirements for Recycled Water Use, Order WQ
2016-0068-DDW, was issued for the SFPUC Recycled Water
Program.

Exterior of Buildings 580 and 581
The schedule of the Westside Project has been increased for several reasons. In the previous quarter, it was assumed that primary power service for Contract B would be required, thus pushing this work into a new future Contract E. While this quarter’s approval of retail power service will decrease the schedule variance, Contract E is still proposed to address required power modifications. An application for the new service was submitted during the quarter, but the timeline for energization is not yet known. Other delays to the project have occurred. The Treatment Facility (Contract A) is delayed due to supply-chain issues related to COVID-19, slow
progress in the commissioning process, and delays in
finalizing the start-up test plan. In addition, the full-scale operation of the treatment facility may be delayed due to an overall shortage of PG&E power capacity at Oceanside Plant.

During the quarter the contractor
completed the following:
installation of structural backfill around the new valve control vault; 24-inch and 36- inch diameter pipeline through-wall connections at the control vault; 24-inch and 36-inch diameter welded steel pipe sections inside the control vault, including spacers for gate valves; a concrete manhole for access to the 24-inch diameter pipe flowmeter and the air relief valve; an outlet sampling station; a 16-inch diameter inlet pipeline replacement; 12-inch diameter high density polyethylene sewer pipe along the access road; and manholes adjacent to the valve control vault. Upcoming work for next quarter includes demolition of the existing roof and roof substructure, installation of a new roof substructure, and factory testing of 24-inch and 36-inch motorized actuators and associated gate valves.

Issues and Challenges:

Manufacturing delays with the gate and butterfly valves and associated motorized actuators has resulted in the contractor resequencing portions of the work in order to minimize any potential schedule impacts. Pacific Gas and Electric has not provided the new electric service necessary for the motorized actuators, water quality sampling equipment, and controls equipment due to an unresolved dispute with SFPUC over a rate tariff. The delayed electrical service will impact the schedule for field testing of the new equipment and for returning the reservoir to service if SFPUC and PG&E are not able to resolve the rate tariff issue by September 2023.

Water Transmission
10034578 CSPL2 Reach 5 Lining Replacement
Crystal Springs Pipeline No. 2 (CSPL2) runs from Crystal Springs Pump Station to University Mound Reservoir. It delivers potable and emergency water supply to San Francisco and to several cities along the Peninsula. Reach 5 of CSPL2, 60" in diameter, from Millbrae Yard to Baden Pump Station (approximately

3.8 miles) in the cities of
South San Francisco and San Bruno is over 80 years old and has extensive lining failures.

This project would replace approximately 3.8 miles of coal tar lining with cement mortar lining (CML), upgrade 34 appurtenances to meet current standards, and improve access and shutdown flexibility for maintenance by installing 5 manway structures and one 60" diameter valve on CSPL2 and one 48" diameter valve on San Andreas Pipeline No. 1 (SAPL1) near Baden Pump Station. In addition, a recent corrosion investigation found a segment of the CSPL2 to be severely corroded across from the Baden Pump Station due to a gas pipeline crossing and will need to be replaced. Since the Sunset Supply Pipeline, San
Andreas Pipeline No. 2, and San Andreas Pipeline No. 3, run parallel to the CSPL2 and are crossed by the gas pipeline, a corrosion investigation will be performed to determine if corrosion has occurred on these
pipelines and if any repairs are needed. The scope of work includes the following: • Complete removal of
coal tar lining • Installation of cement mortar lining • Installation of manway structures • Procurement and installation of isolation valves • Upgrade of appurtenances such as blow-offs, air release valves, etc. to meet current standards • Replacement of pipeline segments • Traffic control • Pavement restoration work. 10035029 As-Needed Pipeline Repairs
Water Supply and Treatment Division's (WSTD) maintenance and inspection program inspects the regional pipeline system on an ongoing basis. However, when repairs are identified to be needed following inspections and when emergency repairs are needed, a contractor is not readily available to perform the repairs. This project will increase system reliability by reducing the duration and number of outages since a prequalified, as-needed contractor will be available to complete repairs immediately following inspections or in emergencies. This project will repair/replace regional pipeline segments that will be inspected over the next five years, in addition to any emergency repairs that may be needed. The initial construction contract will be 3 years and combined with Project 10036840, BDPL1-4 Lining Repair to provide a sufficient guaranteed scope. Subsequent construction contract(s) will be issued to parallel WSTD's inspection program. The scope of work for the initial construction contract is as follows: • Pipeline replacement by open trench • Pipeline repair work • Protecting sensitive (wetland and creek) areas • Protecting utilities and infrastructure • Traffic control • Site/vegetation restoration • Paving restoration • Dewatering and providing temporary safe entry.
10036839 BDPL4 PCCP Repair
Historically, when pre-stressed concrete cylinder pipe (PCCP) fails due to breaks in the spirally wound A3
Appendices Q4-FY2022-2023 (04/01/23 - 06/30/23)
wire, the high-pressure failure can have catastrophic consequences. Some segments of the Regional Water System are constructed of PCCP. From recent inspections of Bay Division Pipeline No. 4 (BDPL4) Segment D, constructed of PCCP, a large number of wire breaks and circumferential cracks were found in the last

1.25 miles of pipeline that parallels Edgewood Road in Redwood City. In addition, several leaks have surfaced at circumferential cracks and where the pipeline transitions from PCCP to steel. Segments where wire breaks are concentrated will need to be repaired/replaced to prevent catastrophic failure and circumferential cracks and leaks will also be repaired. The first phase of this project will be to repair segments where there are high concentrations of wire breaks, wide circumferential cracks and active leaks.

This first phase will include planning, design and construction of repairs. The second phase of the project will be to address the remaining 1.25 miles of pipeline, which includes planning, design and partial encumbrance of a construction contract. The project budget will be reevaluated following completion of the Alternatives Analysis for the second phase. The first construction contract will increase system reliability by rehabilitating approximately 650 feet of 84-inch diameter BDPL4 PCCP in Redwood City and includes the following work: • Excavation, shoring, back filling, and compaction • Demolition of PCCP •
Replacement of approximately 530 feet of pipeline
by open trench • Slip lining approximately 120 feet of
pipeline • Protecting sensitive (wetland and creek) areas and utilities/infrastructure • Traffic control and • Site/vegetation and paving restoration.
10036840 BDPL 1-4 Lining Repair
Water Supply and Treatment Division's (WSTD) ongoing pipeline inspection program has identified segments of the BDPL 1-4 and other regional pipelines that require lining repairs. In addition, this project will retain an as-needed contractor to repair linings identified to be deficient by WSTD over the next 5- years. This project will repair the lining in segments of the BDPL 1-4 and other regional pipelines over the next 5 years. The initial construction contract for this project will be 3 years and combined with Project 10035029, As-Needed Pipeline Repair to provide a sufficient guaranteed scope. Subsequent construction contract(s) will be issued to parallel WSTD's inspection program. The scope of work entails the following: • Cement mortar lining (CML) repair including removal, handling and disposal of existing coal tar lining • Dielectric lining repair • Dewatering and providing temporary safe entry measures, such as line stops, blind flanging, roll out spool pieces, welding bulkheads, etc. 10015071 Corrosion Control
This project will implement the corrosion protection and control program as recommended in the Corrosion Control Master Plan completed in August 2010. Sites identified w ith t he w orst l evels o f c orrosion were bundled up in the master plan in three phases. Each phase will take several years to implementation. The scope for all phases will be similar, but the number of sites will vary at each phase. Phase 1 construction work for ten sites was completed and accepted on August 27, 2019. Phase 2 has eleven sites and is currently in the design phase. Phase 3 is anticipated to include up to twenty sites depending on the funding.

Water Supply & Storage
10015232 Merced Manor Reservoir Facilities Repairs
The Merced Manor Reservoir was upgraded in 2004 to seismically strengthen and repair the roof structure and foundations. After the completion of the upgrade, spalling of concrete at various locations on the roof structure was observed over the years due to the constant temperature gradient experienced in the roof structure. The design of the seismic retrofit of Merced Manor Reservoir was done without the benefit of the lessons learned from later roof retrofits and construction at Sunset North Basin and University Mound North Basin where the effect of temperature load on the roof due to expansion and contraction was analyzed and designed to accommodate the temperature loading. The scope of this project includes performing structural analysis of the effect of temperature gradient on the existing roof structure design; developing design modifications of the roof structure to accommodate the expansion and contraction loads; and construction of the roof modifications and repair of the spalled concrete. 10036998 Turner Dam and Reservoir Improvements
Turner Dam is a 195-foot-high earth embankment dam that was completed in 1965 and impounds San Antonio Reservoir in the East Bay. The dam is regulated by the California Division of Safety of Dams (DSOD).

Watershed & Lands Management
10015110 EBRPD WATER SYSTEM
As a mitigation for the Calaveras Dam Replacement Project, the SFPUC agreed to construct new potable water distribution facilities for the Sunol Regional Wilderness Park (SRP), managed by the East Bay Regional Park District (EBRPD). The EBRPD owns and maintains a water system located at SRP Headquarters which previously supplied potable water to four park facilities, as well as drinking water fountains and picnic areas interspersed throughout the park. Currently, the water system serves non potable water for use by EBRPD employees only. Since the system stopped producing potable water due to supply and sanitary deficiencies, EBRPD has been supplying park visitors with bottled water trucked in by a contracted vendor. The project purpose is to provide a reliable water supply for potable use at the EBRPD facilities and to provide potable uses at the SRP.
10015108 Sneath Lane Gate/North San Andreas
The 2001 Peninsula Watershed Management Plan identified the need for a new trail connection between San Mateo County's Crystal Springs Regional Trail (North San Andreas) to Golden Gate National Recreation Area's (GGNRA) Sweeney Ridge property at the Sneath Lane Gate. The trail is a critical connection among existing regional trails at the north end of the Peninsula watershed, that will serve hikers, bikers and equestrians.
10015113 Southern Skyline Blvd Ridge Trail Extension
The Bay Area Ridge Trail project was started in 1987 by the Bay Area Ridge Trail Council to create an approximately 550-mile long continuous trail for hikers, mountain bicyclists, and equestrians along the ridgelines overlooking San Francisco Bay. The objective of the project is to provide access to the Peninsula watershed, to enhance educational opportunities, and to ensure watershed protection. South of Highway 92, this proposed extension project would construct a 6-mile-long trail on the Peninsula Watershed in San Mateo County between Highway 92 and the Golden Gate National Recreation Area's (GGNRA) Phleger Estate. The project consists of a 6' foot wide, all-weather surface trails; retaining structures to stabilize cut and/or fill slopes; drainage facilities; a 15,000-square-foot parking lot accommodating up to 14 cars; two pre-fabricated restrooms along the trail; site security features; and landscape restoration. North of Highway 92, the project includes construction of a trail segment adjacent to the Fifield Cahill Trail that is compliant with the Americans with Disabilities Act, a 16,000-square foot parking lot, and one pre- fabricated restroom. In addition, the project includes the following related construction: • Removal of 160 A6

The SFPUC has identified landslide and erosion damage that have destabilized service roads (East Shore Service Road and West Shore Service Road) and adjacent areas in three locations on San Francisco Peninsula Watershed lands situated along the San Andreas Reservoir in San Mateo County. The project is to evaluate and repair the damage, and to implement long term solutions for SFPUC staff and contractors to continue to use the roads to access, operate, and maintain SFPUC facilities and watershed lands.

Construction for these locations can be done through phases to accommodate budget cash flow.

Buildings and Grounds
10033555 Rollins Road Building Renovations (CUW27703)
The SFPUC purchased a property that was previously leased long term on Rollins Road in Burlingame, San Mateo County, in September 2017, securing ownership of an additional 10,000 square feet of office space for the SFPUC Water Enterprise (WE). A capital project was initiated in 2018 for tenant improvements. In June 2020, the project scope for the 1657 Rollins Road was decreased significantly, and the scope of the Millbrae Yard Lab & Shop Project was increased. The program for Rollins Road Building Renovation Project will be achieved at the Millbrae Yard by adding two additional floors to the laboratory building as part of its Phase 1 project. The expanded laboratory building will accommodate the Rollins Road building staff. As a result of the scope change, personnel at 1657 Rollins Road will relocate to Millbrae Yard campus following the completion of the Millbrae Yard Lab & Shops Project. 10034526 Millbrae Warehouse Settlement & Admin. Bldg. HVAC This project will construct improvements for two buildings located at the Millbrae Yard facility, the Millbrae Warehouse and the Administration Building. The Millbrae Warehouse Settlement project will provide a long term repair for the displacement (settlement) of the slab between the loading dock and the offices. The slab settlement resulted from expansive clay layers located seven feet below the top of the existing concrete slab. For the Millbrae Administration Building HVAC Upgrades, this project will provide long term reliable and economical improvements to heating and cooling systems. Two separate construction contracts will be used for the Millbrae Warehouse Settlement repairs and the Administration Building HVAC Upgrades. Construction for the Millbrae Warehouse loading dock repair is forecasted to begin in 2021 whereas the Millbrae Administration Building HVAC Upgrades construction is forecasted to begin in 2022. 10015124 Sunol Long Term Improvements
The project includes redevelopment of the existing Sunol Yard and construction of a Watershed Center near the Sunol Water Temple. Most of the existing structures at the Sunol Yard date back to 1930 and were converted from the original purpose, residence and barn, to office and shop spaces. The structures contain lead-based paint, asbestos, bats, and bat guano, and did not meet current building, health, or safety codes.

The project will demolish six existing dilapidated structures at the Sunol Yard and construct a LEED Gold administration building, shops, fuel station, backup generator system, truck wash station, paving and site restoration. Additional scope was requested for the Watershed Center that was not included as part of the construction contract. The scope is under review by Water Enterprise for consideration and budget. The scope includes backup generator to power the facility, 100 space parking lot, History terrace exhibit, picnic area restoration and fixtures, composing toilets, convert temporary construction areas to permanent areas for WSTD and NRD use and revisions to the interior exhibits. The scope of Center (Phase B) will consist of A7
Appendices Q4-FY2022-2023 (04/01/23 - 06/30/23)
the following: • Construction of a one-story LEED Gold facility that will include an interpretive display exhibit area, a freshwater stream profile aquarium, history display alcoves, a watershed discovery lab classroom, a community multi-purpose room, restrooms, an entry plaza, a reception area, patios, and administrative of
fices. • Construction of a 2.5-acre discovery trail area with native plant landscaping, irrigation, meandering trails, seating areas and water and landscape features. • Site restoration of the Temple area forecourt. • Construction of new stairs and ramps to the picnic area. • Installation of underground utilities. • Site restoration and paving.
10015128 Millbrae Yard Laboratory and Shop Improvements SFPUC has determined that the existing Millbrae Administration Building must remain operational following a major earthquake, and therefore needs to be retrofitted or replaced to meet essential facility requirements. SFPUC also wants to expand the
existing Millbrae Administration Building to merge and
house the Water Enterprise staff and equipment from the Rollins Road Facility. This project is necessary to provide Water Enterprise personnel a long term and sustainable campus, and allow the consolidation of work groups for increased staff efficiency. This project will also alleviate shortage of program space, increase efficiency of operations, improve employee working environment with improved heating, ventilation, and air conditioning, improve employee health and safety, and enhance site and building security. A recent planning study has identified several alternatives to meet the project goals. The selected alternative for the Millbrae Yard campus improvements will be implemented in three phases. Phase 1 includes a new laboratory office and new south shop building to alleviate Water Enterprise undersized and outdated workspaces and desire to relocate mission-critical functions to code-compliant structures. This project will provide additional space in the laboratory building by constructing two additional floors on top of it to accommodate the relocation of all personnel from Rollins Road Facility. Phase 2 includes demolition of the existing Administration Building and construction of a new consolidated Administration Building adjacent to the new laboratory building to accommodate other Water Enterprise staff. Phase 3 includes new covered storage for materials and equipment. Only the scope of work for Phase 1 will be implemented under this project to meet near-term needs, minimize disruptions to operations, and allow gradual buildout of the master plan to stay within the 10-year CIP budget. The Phase 1 scope includes the following: • Construct a new 50,000 square foot 3-story laboratory building • Construction a new 12,800 square foot shop building • Renovate an existing 7,440 square foot warehouse • Perform site improvements such as driveways, hardscape, landscape, and parking (approximately 400 spaces).

APPENDIX A. PROJECT DESCRIPTION

WATER LOCAL
Water Transmission
10033816 Potable Emergency Firefighting Water System
This project provides funding for the design and construction of about 2 to 3 miles of large diameter earthquake resistant pipeline to improve the fire water and potable supply reliability in the western area of San Francisco, particularly in the Sunset and Richmond Districts. This project is part of a larger effort to construct approximately 14 miles of the Potable Emergency Firefighting Water System (PEFWS), which also includes two planned pump stations. Current funding will fund the aforementioned 2 to 3 miles of pipeline and design work for a Lake Merced Pump Station. The pipeline will be designed as a potable AWSS pipeline, meaning it will convey low pressure potable water with connections to the distribution system during normal operations but can be isolated with motorized valves and operate under high pressure for firefighting after a major seismic event or emergency conditions by activating associated pumps. This funding will provide planning and design through FY 22-23 with construction funding in FY24 and 25.

Additional funding will be provided by existing Earthquake Safety & Emergency Response (ESER) general obligation bond funds, with additional funding possibly approved in the March 2020 ESER referendum. The total Local Water funding commitment to this project is $55M with $12M carryover from FY 18-19 and FY19-20 budgets.
10033818 Town of Sunol Pipeline
Since 2000 the SFPUC has replaced the majority of the Town of Sunol pipeline system through the Town of Sunol Fire Suppression project, except for two segments. This project will complete the replacement of the last two segments of the system, by replacing sections of the pipeline that crosses the Arroyo de Laguna Creek (Creek Crossing) and under Highway 680. The upstream section of pipeline that feeds both the potable line and fire suppression line to the Town of Sunol is exposed under the creek and in danger of failing under Highway 680. Pipeline failure at either location has significant consequences, since all fire and potable water in the Town of Sunol is dependent on the rehabilitation of this 12" line. This project will reduce maintenance from pipe breaks and have less main flushing which may lower impact on operating expenses. This project is broken up into two portions and the scope of work will include the following:

Creek Crossing: •Replace approximately 550 feet of 12" diameter pipeline crossing Arroyo de Laguna Creek with 12" diameter Ductile Iron Pipe (DIP) class 53 •Open cut trench across the creek •New tie in points with gate valves •Creek restoration and tree removal in pipeline alignment Highway 680 Crossing:
•MOU agreement with Alameda County Transportation Commission (ACTC) to replace existing 12" diameter Town of Sunol pipelines under Highway 680 for $1.3M. 19063 Local Water Conveyance/Distribution System
This long-term program funds management of linear assets in the potable water distribution system between transmission or storage and final customer service connection. 1. Main Replacement Program:
replaces and renews feeder and distribution mains for the 1,230 miles of pipe distribution system.

Improvements include replacement, rehabilitation, relining, and cathodic protection of all pipe size categories to extend or renew pipeline useful life. Coordination with construction projects by other City agencies, especially SFPUC Sewer and DPW Paving, is emphasized to optimize efficiencies and minimize customer disruptions. Starting in FY21-22, a new L-Taraval Transit Project has been created to provide separate funding for the main replacement project along this major transit corridor, where street improvement projects by other agencies (CalTrans, SFMTA, SFCTA, DPW) and are more expensive to implement due to their complexity, traffic and transit impacts, and multi-agency coordination. The L- A9
Appendices Q4-FY2022-2023 (04/01/23 - 06/30/23)
Taraval Project will provide separate project funding for the 4 miles of main replacement at a cost of $6.0M per mile. Additionally, in FY21-22, a new Better Market Street Project has been created to provide separate funding for the water main replacement along the Market Street Corridor to be constructed over a period of 7 years with the assumption of 0.5 miles per year. The proposed budget will include the following: 1) replacement of distribution pipelines at $4.5M per mile; 2) replacement of 1 mile with seismically reliable pipelines at $6.0M per mile; and 3) Pipe relining at $3M per mile. FY20 budget will be allocated from existing budget balance.

Local Water Supply
10015239 Lake Merced Water Level Restoration
The project consists of the following subprojects. (1) The City of Daly City is proposing and working in coordination with the SFPUC to implement the Vista Grande Drainage Basin Improvements project to address storm related flooding in the Vista Grande Watershed Drainage Basin while providing the benefit of restoring connection to the natural watershed of Lake Merced, (2) The SFPUC is evaluating diversion of highly treated recycled water from the new Westside Recycled Water facility into Lake Merced to increase ad stabilize lake levels.
10015240 San Francisco Groundwater Supply
This project consists of two phases, which combined will provide an annual average of 4 mgd of groundwater to San Francisco’s municipal water supply, and improvements at the existing San Francisco Zoo Well No. 5. Phase 1 is divided in two separate contracts, which are Contracts A & B. Contract A work for building four new groundwater well stations in the western part of San Francisco is currently in the final construction phase. Contract B work for installing buried piping to connect three of these well stations to the Sunset Reservoir was completed and accepted on December 21, 2015. Groundwater from the fourth well station was piped to the nearby Lake Merced Pump Station, where it was distributed to both the Sunset Reservoir and Sutro Reservoir. Phase 2 has Contract C work for installing buried piping and converting two existing irrigation well facilities in Golden Gate Park to groundwater supply wells is currently in the final construction phase, and would be implemented after completion of the CUW30201, San Francisco Westside Recycled Water Project. Improvements at the existing San Francisco Zoo Well No. 5 were completed and accepted on February 15, 2007.
10015242 San Francisco Westside Recycled Water
This project includes all facilities to produce and deliver about 2 mgd of recycled water for irrigation use in the western end of San Francisco. The project includes a new recycled water treatment facility consisting of membrane filtration, reverse osmosis, and ultraviolet light disinfection; a 1.1 million gallon storage reservoir; distribution pumping facilities; and 5 to 6 miles of new pipelines.

Local Tanks/Reservoir Improvements
10015223 College Hill Reservoir Outlet
This project provides funding for the design and construction of the College Hill Reservoir Outlet Structure and Pipeline Upgrade Project to address seismic, water quality, electrical, structural, and other deficiencies. This project includes installation of a new control valve vault; replacement of reservoir inlet and outlet piping; replacement of reservoir transmission pipelines up to Cortland Avenue; reservoir roof replacement; and miscellaneous piping, security, site access, electrical, instrumentation, and water quality improvements. This project is currently in final design phase with a 24-month construction duration starting in 2020. The estimated budget is $18 million with $14M in funding provided for FY1920 and additional $3M provided for FY2021 and $1M FY2021 for roof replacement.

Pump Stations
10015231 Harding Park PS
This project funds long term improvements to the Harding Park Pump Station to increase reliability and correct conditions that have led to the premature corrosion and failure of critical components. The current design places the pumping facility on top of the recycled water reservoir leading to high humidity levels within the facility. This project will seal the reservoir from the pump room, improve the HVAC system for humidity control, and relocate critical electrical panel and components out of the pump room. The project will also modify the current electrical feed to allow for the safe maintenance of the water pump electrical components while leaving the buildings lighting and auxiliary loads powered.

Buildings and Grounds
10037249 New CDD Headquarters
The City Distribution Division (CDD) Headquarters, currently located at 1990 Newcomb Avenue, San Francisco, was constructed in 1962. The majority of CDD's staff are located at Newcomb (approx. 260 people). Existing facilities include administrative offices, warehouse, shops, materials and equipment storage and vehicle fleet. CDD oversees the retail water distribution system with the City and County of San Francisco, responsible for the physical infrastructure of San Francisco's potable, auxiliary water system, groundwater, and recycled water systems. CDD's responsibilities include 24/7 emergency response to water main breaks and two-alarm or larger fires in addition to day-to-day operations and maintenance of over 1,250 miles of water main, 12 reservoirs, 9 pump stations, 7 hydro pneumatic stations, 6 tanks, the water meter program serving over 176,000 customers, and maintaining CDD's physical plant, equipment and vehicles and over 1,100 acres of grounds throughout the City.

Emergency Firefighting Water System
EFWS-PL EFWS PL - EFWS Pipelines
The Emergency Firefighting Water System(EFWS) includes several methods of delivering water to suppress fires during emergency situations. EFWS is vital for protecting against the loss of life, homes, and businesses from fire following an earthquake and non-earthquake multiple-alarm fires. One EFWS component is a high-pressure fire-suppression water system, formerly known as Auxiliary Water Supply System (AWSS), which was originally built in the decade following the catastrophic 1906 San Francisco earthquake. It consists of a resilient 135-mile high-pressure pipeline network, a high elevation reservoir, two large capacity tanks, two high-pressure seawater pumping stations, and manifolds that allow fireboats to inject Bay water into the City’s pipelines. The Potable Emergency Firefighting Water System (PEFWS) will bring a seismically resilient high -pressure firefighting water system to the western neighborhoods of San Francisco, while also creating a seismically resilient pipeline that supplies drinking water to the west side
during non fire situations. The proposed overall project will install over 14 miles of seismically resilient pipelines in multiple phases as funding is provided. The system will be capable of providing water to the SFFD firefighters at the high pressure needed to combat large fires after a seismic event.

The proposed pipelines will be fed by pump stations delivering 30,000 gallons per minute with services to the Richmond and Sunset Districts. Fireboat manifolds allow fire boats to pump seawater from the bay into the EFWS. Existing fireboat manifolds at Fort Mason and Pier 33 ½ are located on piers of unknown condition and are likely susceptible to seismically induced failures. Rehabilitation of manifolds and connector pipelines is required at Fort Mason and Pier 33 ½ to provide adequate access for firefighters.
