iv
WECIP Quarterly Report Q3-FY2022-2023 (01/01/23 – 03/31/23) design phase. Survey field work was completed and base maps were created for use during design. Exploratory geotechnical field work was also completed and a geotechnical data report was prepared.
 For As-Needed Pipeline Repair and for the Bay Division Pipeline 1-4 Lining Repair projects (which will be constructed together), a draft technical memorandum summarizing the locations of new valves and proposed pipeline safe entry measures, which will be the basis for the addendum to the Conceptual Engineering Report (C ER), was presented to the Health and Safety team this quarter. Survey field work was completed and base maps were created.

Geotechnical field work was also completed and a draft geotechnical data report circulated for review.
 For the Corrosion Control project, Notice to Proceed was issued in March to contractor.  For Bay Division Pipeline Pre-Stressed Concrete Cylinder Pipe Repair project, a draft Needs Assessment Report (NAR), evaluating 1.3 miles of Bay Division Pipeline No. 4 Pre-Stressed Concrete Cylinder Pipe (PCCP) in Redwood City was completed and circulated for review. It identified 6 segments of high priority pipeline for repair in a first phase.  For the Pilarcitos Dam and Reservoir Improvements project, the project team completed development of evaluation criteria for the alternatives analysis and a study of environmental opportunities and constraints.
 For the San Andreas Dam Facility Improvements project, the project team continued analyzing the nine alternatives identified during the condition and needs assessment phase. All the lab testing has been completed, and the project team started to perform material characterization in evaluating the stability of the dam embankment. Three additional horizontal borings at the right abutment, where a potential new spillway will be located, were completed.  For the Turner Dam and Reservoir Improvements project, the project team completed testing of the samples collected from the geotechnical investigation field work, began performing materials characterization report, and began preparing the geotechnical data report. In addition, the team has initiated the assessment of the emergency drawdown capacity and structural stability of the outlet works.
 For the Southern Skyline Blvd Ridge Trail Extension project, the SFPUC received grant funding authorization from Caltrans, allowing the project to proceed to bid advertisement.  For the SA-1 Service Road/Ingoing Road project, the 95% Design milestone was achieved.

The project team is incorporating review comments into 100% Design.  For the Alameda Creek Watershed Center under the Sunol Long Term Improvements project, negotiation on the substantial completion date, remaining construction items, public artwork, and deficiency list work continued. The recent winter storms damaged fences, gates, and landscaping, and caused erosion on the access road to the Agricultural Park site. The berm along the building settled and caused damage to several pipelines within the berm.  For Millbrae Yard Laboratory and Shop Impr ovements project, space planning and cost estimating were updated based on a new proposed conceptual scheme that includes locating the new administration building within the existing tenant area.  For Rollins Road Building Renovations project, construction is complete. Administrative close out is in progress.

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
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 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 Q3-FY2022-2023 (01/01/23– 03/31/23) 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 January 1, 2023 and March 31, 2023. This document serves as the third (3rd) 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 Q3-FY2022-2023 (01/01/23– 03/31/23) Figure 2.1 shows the total Current Approved Budget for the 25 Regional projects in each phase of the program as of March 31, 2023. The number of projects currently active in each phase is shown in parentheses.

3. CAPITAL IMPROVEMENT PROGRAM COST SUMMARY
Table 3 provides an overall program-level cost summary of the Regional Water Program. It shows by categories of projects the Expenditures to Date, Current Approved Budgets, Q3/FY22-23 Forecast Costs, Cost Variance between the Current Approved Budgets and Forecast Costs, and Variance Over Reporting Period (difference between cost forecasts reported in Q2/FY22-23 and in Q3/FY22-23).

The total Current Approved Budget (including Regional and Local Programs) and Current Forecast Cost at completion are $3,266.5 million, and $3,085.0 million, respectively. The Current Approved Budget and Forecast Cost at completion for only the Regional Water Program (including construction contingency) are $995.1 million and $1,111.6 million, respectively.

The project budgets and schedules, including for new projects, that were included in the 10-Year CIP budget proposal that was presented to, and approved by, the Commission on February 8, 2022 became fully approved in Q1FY22-23 through Board of Supervisors action. Any variances from the budgets and schedules approved on February 8, 2022 are reported herein.

During the quarter, there were no new cost variances reported for the Regional program. The overall 2022 Regional WECIP negative Cost Variance of $116.48M in Table 3 was reported in previous quarters and can be attributed to the following projects and their variances provided below; the reasons for the project variances are reported in Section 7:

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 95% design package, cost
estimate and construction schedule were submitted and
reviewed, and workshops and presentations were held. The 100% design started, and environmental work continued. The washwater recovery system was incorporated into the design package. The project will apply for State Revolving Fund loan financing which would result in substantial cost savings. The environmental requirements will be fulfilled by adding an amendment to the SVWTP Expansion and Treated Water
Reservoir Environmental Impact Report prepared under the Water System Improvement Program. The amendment will
include the SVWTP Ozone, Polymer Feed Facility and the
SVWTP Short Term Improvements projects.

Issues and Challenges:

The budget variance is due to further design developments, 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 in the Construction phase needed to construct the facility following further design developments as well as additional time to mitigate risks anticipated for the Bid and Award phase.

During the reporting
period the 95% design work continued,
and utility pothole and site survey work was completed. The environmental requirements will be fulfilled by adding an amendment to the SVWTP Expansion and Treated Water
Reservoir Environmental Impact Report that was prepared under the Water System Improvement Program.

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 nine scope items. In addition, a longer construction duration is 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.

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.

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.

Progress and Status:

The project team continued analyzing the nine alternatives identified during the condition and needs assessment phase.

All the lab testing has been completed, and the project team started to perform material characterization in evaluating the stability of the dam embankment. Three additional horizontal borings at the right abutment, where a potential new spillway will be located, were completed, which concluded the
geotechnical drilling program in support of the Alternative Analysis and Evaluation.

Issues and Challenges:

The approved schedule assumed the construction work for the spillway and emergency drawdown outlet structures
would be completed under Contract B, reaching substantial completion two years before the dam embankment work
under Contract A commenced. Based on the preliminary
needs assessment and condition assessment findings, it is now recommended that the alternatives analysis also include analysis for combining the two scopes under a single
construction contract. This combined construction contract alternative would impact the project overall schedule. As the project is still in early planning phase, the overall project schedule and budget will be reforecast once the scope of work is defined at the end of the alternatives analysis.

project team is incorporating review comments into the 100% design. Final design and contract documents are anticipated to be completed by June.

Issues and Challenges:

The budget variance is due to a combination of the additional scope of a debris boom and anchorage system within the
reservoir, upstream of the San Andreas Dam and Spillway, and the deleted scope of the 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 with the changed scope.

Administration Building HVAC Upgrades (JOC): The scope of work is now the retrofit of the existing heating, ventilation, and air conditioning (HVAC) system inside the building rather than replacement of the HVAC system external to the building. A revised cost proposal for this limited scope was received from a JOC contractor and is currently being reviewed. The cost proposal includes estimated cost of modifying several areas in the ceiling to be able to access multiple HVAC boxes. This modification is needed both for the proposed construction and also for future maintenance.

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 the building. The revised cost proposal from a JOC contractor for the current limited scope exceeds the JOC task order cost threshold of $706K. The scope will be prioritized, and the JOC contract scope further limited to allow performance within the JOC threshold.

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.

(Contract B): During the reporting period, negotiation on the substantial completion date, remaining construction items, public artwork, and deficiency list work continued. The glass exhibit floor was replaced. The recent storms caused damage to fence, gates, and landscaping as well as erosion on the access road to the Sunol Agricultural Park where the
Watershed Center is located. The berm along the Watershed Center building settled, causing damage to several pipelines within the berm. The submittals and fabrication work
continued for the exhibits, furniture, fixtures, equipment, site signage, and bluestone etching. Work on the operation and maintenance manuals, training, as-builts, and extended
maintenance coordination all continued.

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. The exhibit redesign occurred while construction was ongoing and will extend the
construction contract approximately one year beyond the original final completion date. Exhibit redesign will also require extended overhead from the contractor and additional project management, construction management, and design support services. Additional project schedule variance is due to a 2-year extended maintenance period added to the
construction contract.

35 I. Regional WECIP Quarterly Report Q3-FY2022-2023 (01/01/23 - 03/31/23) 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.

updated cost estimate for a new
proposed conceptual scheme were completed, and are
currently being reviewed. The new scheme includes
appropriation of the entire tenant area for SFPUC staff use and locating the new administration building within the former tenant area. Preparation of the Request for Proposals (RFP) for engineering services by SF Public Works Contracts group continued to progress. The RFP focuses on the civil,
structural, mechanical, electrical, and plumbing services.

Issues and Challenges:

The schedule variance is due to delay in construction for budgetary reasons; increased project scope leading to
increase in both bid and award and construction phases
forecast; 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
resulting from the alternatives planning study, including changes for the laboratory building, 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 formally
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 Q3-FY2022-2023 (01/01/23– 03/31/23) 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 January 1, 2023 and March 31, 2023. This document serves as the third (3rd) 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 Q3-FY2022-2023 (01/01/23– 03/31/23) Figure 2.1 shows the total Current Approved Budget for the Local projects in each phase of the program as of March 31, 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 March 31, 2023: Pre- construction, Construction, and Post-construction.

Local WECIP Quarterly Report Q3-FY2022-2023 (01/01/23– 03/31/23) Figure 2.3 summarizes the environmental review status of the Local projects as of March 31, 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 forecasted mileage for FY23 is 8.2 miles which is reduced from the target of 15 miles due a reduction in the program budget for FY22 and FY23.

4 II. Local WECIP Quarterly Report Q3-FY2022-2023 (01/01/23– 03/31/23) Water main replacement projects with construction underway in the 3 rd quarter of FY23 included the City streets of 19th Avenue, Vicente Street, Prospect Avenue, L-Taraval Segment B, and Diamond Street. The Notice to Proceed for Laidley Street project was issued on March 6, and the water work is anticipated to start in the 4th quarter of FY23.

Figure 2.5 shows the annual total program expenditure by fiscal year for the pipeline replacement
program. The budgeted cost per mile has been updated for FY23 from $5.4 million per mile to $5.8 million per mile for replacement of water distribution mains due to rising costs of materials and labor associated with inflation. The updated cost per mile for streetscape, transit, or ERDIP type projects is approximately $8.6 million per mile.

7. PROJECT STATUS REPORT
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.

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:

The environmental team
received comments from the SF
Planning Department on the proposed CEQA addendum.

Planning's comments about tree restoration required
additional design coordination to determine adequate areas to replant trees and also how to reduce tree removal.

Response to these comments delayed CEQA completion;
however, the design and bid advertisement is anticipated to be on schedule. The design team anticipates completion of the 95% design package in the next quarter. New permanent and temporary construction easements are being negotiated for the pipeline alignment at the Sunol Glen School. The school has been slow to respond to the appraisal process due to their focus on recovery from property flooding caused by the winter storms. The pipeline within the creek has been further exposed and is more visible due to removal of
vegetation and trees. The project will reinstall coverage within the creek to prevent future scour from exposing the pipeline again.

Issues and Challenges:

As reported last quarter, the budget variance is due to the new requirement of permitting agencies that the existing Town of Sunol Pipeline be removed from the creek and also to include higher escalation costs.

contracts. (A) Vista
Grande Drainage Basin Improvement managed by Daly City; (B) Lake Merced Aeration Mixing System - Phase 1 (JOC
Contract); and (C) Lake Merced Aeration Mixing System - 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 the outflow structure at Fort Funston. Daly City is negotiating with SF Public Works for a major
encroachment permit for construction of the diversion
structure for the approved flows to Lake Merced. This
diversion structure would be constructed under John Muir Drive within the City’s right of way. The Daly City staff working on this project have prepared an updated Lake
Management Plan, which was reviewed by SFPUC and has
been updated to address SFPUC comments. The updated
plan was submitted to the RWQCB in April 2023 for their review and approval. Daly City received approval for $62.8M in funding from the State Revolving Fund and continues to work on attaining remaining project funding. 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 completed a draft evaluation to further study project feasibility and is currently working on an alternatives analysis to evaluate the current design options and provide input to the 35% design documents.

Issues and Challenges:

SFPUC is currently evaluating potential changes to lake resources as a result of updated diversion criteria being proposed by Daly City. Project schedule continues to be impacted by challenges with California Coastal Commission permitting and fund acquisition by Daly City. Following North Lake Looking South East Towards Harding Park

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): Miscellaneous mechanical, electrical and architectural finish work continued in Buildings 580 and 581. Issues related to the Process Instrumentation and Control System were resolved. Work continued the
Operations Manual and Standard Operating Procedures
(SOPs) for the new treatment facility. A Draft Start-up Test Plan Narrative was submitted by the Contractor for review.

Distribution Pump Station and Reservoir (Contract B): City staff reviewed the revised Start-Up Testing Plan, and
workshops were held with the Contractor to clarify comments.

Pump vibration testing was completed. Pipeline (Contract C) is complete. Irrigation System Retrofit (Contract D):

Installation of Recycled Water signage in Golden Gate Park began. Punchlist walkthrough of the retrofit work continued. A Draft Irrigation System Operations Plan and Standard
Operating Procedures (for recycled water use) were prepared for Golden Gate Park and issued for review by SF Recreation and Parks. Regulatory: Sections of Golden Gate Park will need to be retested in the next quarter after irrigation system repairs.

Issues and Challenges:

The schedule of the Westside Project has been increased for several reasons. The change that is driving the overall project schedule is the potential change to the power service to the new Distribution Pump Station (Contract B). PG&E has
suggested that the service be changed to Primary instead of Secondary. This change will add new scope to the project Exterior of Buildings 580 and 581
and will delay recycled water delivery to Lincoln Park Golf Course by several years. A response from PG&E regarding the final power service approach has not been received. A fifth construction project (Contract E) is proposed to address required power modifications. Other delays to the project have occurred. The Treatment Facility (Contract A) is delayed due to slow progress and supply-chain issues related to COVID-19, and delays in finalizing the start-up test plan. In addition, the full-scale operation of the treatment facility will be delayed due to lack of PG&E power capacity.

Work is ongoing to complete the control valve vault structure and replacement of the 16-inch diameter welded steel pipe inlet. Upcoming work for next quarter includes installation of structural backfill around the control vault, 24-inch and 36-inch diameter pipeline
connections at the vault, and reservoir roof substructure replacement.

Issues and Challenges:

The overall project budget and schedule increases were
approved by the Commission on March 28, 2023 to repair
significant damage to the reservoir roof’s wooden
substructure and associated plywood sheathing that was
identified by the contractor. The entire roof substructure will require replacement rather than the previously anticipated partial repair. The Contractor is currently experiencing a valve procurement delay with the control valve vaults scheduled to arrive in September. The time extension associated with the roof work is anticipated to mitigate valve procurement delays because the work may proceed in parallel when the valves arrive.

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 Q3-FY2022-2023 (01/01/23 - 03/31/23)
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.

This project description is for all three phases. Scope of work includes the following: • Furnish and install cathodic

The scope of work includes the following: • Removal of approximately 2.2 miles coal tar lining • Installation of approximately

2.2 miles of cement mortar lining • Removal of 1.5 miles of existing CSPL1 • Pipeline installation work by open trench • Upgrade of appurtenances such as blow-offs, air release valves, etc. to meet current standards • Traffic control • Pavement restoration work.

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.

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.

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

trees • 9.3 miles of wildlife friendly security fencing • Grading and drainage work • 2000 LF soldier pile retaining walls • Paving of two trailheads parking areas with educational signage • Protecting sensitive habitat • Traffic control • Site/vegetation restoration. 10030771 SA-1 Service Road/Ingoing Road
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 Q3-FY2022-2023 (01/01/23 - 03/31/23)
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 Q3-FY2022-2023 (01/01/23 - 03/31/23)
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

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.
