*** “A” represents the actual date.
As of the end of the reporting period, the forecasted total pr ogram cost (regional and local projects) is
$4,787.8M, which is the same as the current Commission Approved Budget. All approved change orders (COs) in contracts total $21.8M, and the forecasted remaining contingency is $9.0M. Also, as of the end of the reporting period, all pending and potential COs, and trends total ($8.1M). Therefore, assuming all pending and proposed COs and trends become approved COs, the current forecasted remaining construction contingency is $17.1M. Note that contingency has increased since last quarter in the Sunol Valley Region because the Alameda Creek Recapture construction contract was terminated last quarter and terms were being negotiated during this quarter for close out.
UPDATE ON PROJECTS IN CONSTRUCTION
As of the end of September 2023, WSIP regional construction contracts (including active, completed, and future contracts) are 99.3% complete overall.
As of the end of September 2023, monitored exposure hours on WSIP regional projects totaled 9.9 million construction person-hours. Since the implementation of the WSIP Safety Approach in April 2009, the total lost time incidence rate is 0.51, compared to the U.S. Bureau of Labor Statistics (BLS) industry average rate (2021) of 1.3.
The following is a summary of the progress made, issues encountered, and/or milestones achieved on the remaining WSIP Regional projects currently active in construction.
Alameda Creek Recapture Project
During the reporting period, negotiations continued with the contractor to agree on final contract close- out terms and costs. Remaining unused materials were auctioned for highest resale price possible. The quarry operator continued the design for slope stabilization of the quarry pond banks. iii

Commission approved the civic design review on September 18 for new fencing work at Hickey Blvd,
Colma BART, and Linear Park Well and Treatment Facilities. For Phase 2A (Contract C), the condition
assessment reports described that the well pump at Lake Merced Well Station is in poor condition due
to corrosion. The reports also noted the poor condition of the well pump at Linear Park Well Station due to scale build-up in the bowl assembly. Installation of flowmeter vaults at the Millbrae and Colma BART Well Stations was initiated. For Phase 2B (Contract D), final electrical system design to provide
power to the SSF Main Well was received from PG&E on September 11, and preparation of the draft contract package continued.

WSIP Quarterly Report Q1-FY2023-2024 (07/01/23 – 09/30/23)
1. PROGRAM DESCRIPTION
The Water System Improvement Program (WSIP) is a $4 .8 billion, multi -year capital program to upgrade the City of San Francisco’s regional and local drinki ng water systems. The program will deliver improvements that enhance the City’s ability to provide reliabl e, affordable, high quality drinking water to its 26 wholesale customers and regional retail customers in Alameda, Santa Clara, and San Mateo Counties, and to 800,000 retail customers in San Francisco, in an environmentally sustainable manner. The WSIP i s structured to cost-effectively meet water quality requirements, improve seismic and delivery reliability, and achieve water supply goals.
Built in t he early to mid- 1900s, the water system has many components nearing the end of their working life, with c rucial facilities crossing, or in close proximit y to, three major earthquake faults. The San Francisco Public Utilities Commission ( SFPUC) initiated th e WSIP to repair, replace, and seismically upgrade the system’s deteriorating pipelines, tunnels, dams, reservoirs, pump stations, storage tanks, and treatment facilities.
The program consists of 35 local projects located within San Francisco and 52 regional projects spread over seven different counties from the Sierra foothills to San Francisco. Local projects only benefit San Francisco residents whereas regional projects benefit both City residents and the 26 wholesale agencies that receive water from t he SFPUC. The management of regional projects is divided into 6 regions – San Joaquin, Sunol Valley, Bay Division, Peninsula, San Francisco Regional, an d Support Projects.
The WSIP is funded through the issuance of revenue bonds. Local Measures A and E, which were approved by San Francisco voters in November 2002, allowed for the financing of improvements t o the City’s water system using revenue bonds and/or other forms of revenue financing. Increases in the water rates of retail and wholesale customers are used to pay back the debt service on the bonds.
The program budget and schedule were originally adopted by the San Francisco Public Utilities Commission on March 1, 2003. The program at the time was referred to as the Capital Improvement Program (C IP). The scope of the CIP was changed significantly following the adoption of Level of Service (LOS) goal s in early 2005. The program changes were so substantial that the program was renamed the WSIP and a new program budget and sc hedule were adopted on N ovember 29, 2005.
Since the scope of the 2005 Revised WSIP is in general representative of the program that is in the end stage of being implemented today, the 2005 budget and schedule are considered the “Baseline Budget and Schedule.”
Subsequently, the WSIP Baseline Budget and Schedule were revised in 2007, 2009, 2011, 2013, 2014, 2015, 2016, 2017, 2018, 2020, and 2022, and these revisions were approved by the San Francisco Public Utilities Commission on February 26, 2008, July 28, 2009, July 12, 2011, April 23, 2013, April 22, 2014, December 8, 2015, April 26, 2016, February 14, 2017, April 10, 2018, April 14, 2020, and April 26, 2022, respectively. Refer to Appendix A for a scope description of all the regional projects included in the WSIP.

2.1 Progress Towards Meeting Level of Service (LOS) Goals The scope of the WSIP is based on the following Level of Service (LOS) goals for the Regional Water System: Seismic Reliability, Delivery Reliability, Water Quality Reliability, and Water Supply Reliability.
Each project that reaches construction substantial completion contributes to increasing the overall reliability of the system and achieving progress towards meeting the overall LOS goals for the system.
Table 2.1 lists the projects with their individual Primary (P) and Secondary (S) contributions towards LOS goals and indicates which projects have met their respective LOS goals. As can be seen in Table
2.1, the actual operational service start dates indicate that 41 of the 43 Regional WSIP projects with specific LOS goals have achieved their LOS goals to date. The other 9 Regional WSIP projects do not have specific LOS goals. The WSIP team remains committed to achieving the overall LOS goals established for the system.

1. Construction Costs include the Construction Base Bid and owner-provided equipment/material for all regional and support projects. Those costs do not include any construction contingency. That contingency is reflected as a separate cost category.
2. Delivery Costs include project management, planning, environment al (CEQA, permitting, construction compliance), design, construction management, and engineering support during construction.
3. Other Costs include environmental mitigation, art enrichment, security improvements, and real estate expenses.
4. Support Projects include (1) System Security Upgrades, (2) Programmatic EIR, (3) Bioregional Habitat Restoration, (4) Vegetation Restoration of WSIP Construction Sites, (5) Long Term Mitigation Endowment, (6) Program Management, and ( 7) Watershed and Environmental Improvement Program. Please note that the cost reflected above for support projects only includes “Delivery” and “Other” costs, and “Construction” cost for these projects is included in “Construction Costs” under the Regional Improvement Projects.
5. Expenditures to Date for Construction Contingency for Regional and Support projects correspond to the Total Approved Change Orders on those projects. For projects with ongoing or completed construction, the 2022 Approved Budget for construction contingency includes all change orders and trends as identified at the time of the March 2022 Revised WSIP, or projects in pre-construction, the 2022 Approved Budget for construction contingency includes 10% of the estimated construction base bid
6. Local Water Supply Projects managed as part of the Water En terprise Capital Improvement Program (CIP) are (1) Lake Merced Water Level Restoration, (2) San Francisco Groundwater Supply, (3) San Francisco Westside Recycled Water, (4) Harding Park Recycled Water, and (5) San Francisco Eastside Recycled Water.
7. The budget approved as part of the March 2022 Revised WSIP, plus any additional budget changes approved by the Commission as part of additional contingencies on construction contra cts. 7 WSIP Quarterly Report Q1-FY2023-2024 (07/01/23 – 09/30/23)
8. The WSIP Local Water Supply proje cts underwent a September 2013 re-b aseline. Only the original WSIP portion of the re- baselined costs is reported here. The re maining budget is funded under the Water En terprise CIP and is managed outside the purview of the WSIP.
9. The original $552M estimate of financing cost was based on a memorandum to th e Commission dated November 23, 2005.
10. The financing cost budget of $372M that was included in the March 2022 Revised WSIP includes all financing costs appropriated to date.
11. The actual financing cost
is assumed to match the budgeted financing cost. Fin al reconciliation of all associated financing costs will occur upon WSIP com pletion.

Current Forecast 04/28/20 A 12/18/20 A 06/21/21 A 02/29/24 Progress and Status:
During the reporting period,
negotiations continued with the
contractor on contract termination and final costs. Materials that could not be re-used in the Regional Water System were uploaded to auction sites and many of the items were sold to the highest bidder. As contract terms for close-out were being negotiated, potential and pending change orders and trends were closed out, freeing up construction contingency. Future potential project strategy, schedule, and costs were
discussed. The quarry operator continued the design for slope stabilization of the quarry pond banks.
Issues and Challenges:
The cost and schedule impacts to the project continue to be evaluated as the team negotiates with the contractor on various terms to terminate the contract. The cost and
schedule forecasts for the reporting period remained the same as the previous quarter. The project team issued
deductive change orders to closeout bid items and
reallocated the budget to the construction contingency for use on final contract termination costs. The final contract costs will be negotiated with the contractor upon receipt of the final closeout proposal.

13 WSIP Quarterly Report Q1-FY2023-2024 (07/01/23 - 09/30/23) 10015241 - Regional Groundwater Storage and Recovery
Project Description: The current scope was planned to
be constructed in two (2) phases. Phase 1 included construction of 13 wells to produce 6.2 mgd of dry year supply over 7.5 years. Operating the wells during drought will provide data and insights into how much water can be reasonably expected to be produced, and if additional well stations are needed to reach the desired drought period pumping capacity. Phase 2 included construction of two (2) installed test wells, completion of the South San Francisco (SSF) Main well, pipeline, and other work. The test wells which would not be converted to production wells at this time will allow for determination as to whether the identified sites could be viable production wells, and will provide information to water quality and pumping capacities that can be used for future planning. Phase 2 has been separated into two contracts due to the long lead-time required for easements and permits for work at the SSF Main Well site. Phase 2A includes installation of cathodic protection, well rehabilitation, and other mechanical work. Phase 2B consists of work at the SSF Main Well and pipeline installation to connect the well to Cal Water's treatment facility.

Progress and Status:
This project includes multiple construction contracts: (A) WD-2600 Test well drilling (completed); (B) Phase 1
WD-2668 Well station (13 wells); (C) Phase 2A WD-2878A; and (D) Phase 2B. For Phase 1 (Contract B) WD-2668
conversion of as-built drawings to computer- aided design (CAD) continued. For the remaining work under Phase 1,
design was completed for electrical work for the sample station at Treasure Island Well Station, and preparation of design drawings continued for installation of fencing and gates at several well stations. On September 18, the Arts Commission completed the civic design review and approved the design for new fencing at Hickey Blvd, Colma BART, and Linear Park Well and Treatment Facilities. For Phase 2A (Contract C) WD-2878A, condition assessment reports for both Lake Merced and Linear Park well pumps were
completed, and installation of flowmeter vaults at the Millbrae and Colma BART Well Stations started. The condition
assessment reports described that the well pump at Lake Merced is in poor condition due to corrosion, while the one for Linear Park is also in poor condition due to scale build-up in the bowl assembly. For Phase 2B (Contract D), final electrical system design to provide power to the SSF Main Well was received from PG&E on September 11, and preparation of
the draft contract package continued. South San Francisco continued review of the updated draft license agreement for the use of its vacant lot adjacent to Cal Water’s property for construction staging.
Well brushing at Colma BART Well Facility
Issues and Challenges:
For Phase 2A (Contract C) WD-2878A, the contractor’s
schedule is being updated to reflect the latest anticipated delays in delivery of the refurbished pumps and the new variable frequency drives (VFD) for the pump motors. The schedule will also reflect the recent delay for recommendation for full bowl replacement of the pumps at the Lake Merced and Linear Park Well Stations. These delays due to supply chain issues for needed materials will be better understood by next quarter. For Phase 2B (Contract D), PG&E’s
submittal of final design of an electrical system was delayed, which has impacted final design completion. Update to the project schedule will be reflected in the next quarterly report. 14 WSIP Quarterly Report Q1-FY2023-2024 (07/01/23 – 09/30/23)

APPENDICES Q1-FY2023-2024 (07/01/23 - 09/30/23)
Management, and Close-out Phases have been transferred to the "CUW38401 - Tesla Treatment Facility Project".
NOTE THAT THIS PROJECT HAS BEEN TERMINATED AND THE REMAINING SCOPE & BUDGET HAS BEEN COMBINED WITH THE "CUW38401 - TESLA TREATMENT FACILITY PROJECT". 10015487 WSIP Closeout - San Joaquin
Supplemental Solar Panel Installations – The CUW37301 San Joaquin Pipeline System, including the western segment, eastern segment and facilities, and crossover pipeline projects, achieved final completion in 2013, 2014 and 2015, respectively. During the initial course of operations it was noted the solar panel arrays designed to provide power for the facility equipment were not sufficient to meet all modes of operational demands. This sub-project will re-evaluate the existing photo-voltaic systems and will provide additional solar panels, if needed, to cover power shortfalls and allow the facility to better meet its water delivery reliability LOS goal. This sub-project consists of three sites: Oakdale, Knight Ferry Throttling Station, and San Joaquin Junction No. 4. The scope of work includes: o Re-evaluation of the existing photo-voltaic systems at these three (3) locations before proceeding with modifications to the existing arrays, o If determined necessary to meet current power demands, furnish and install new supplemental solar arrays mounted on concrete pads within security fence enclosures, o Connection to and integration of the new solar panels into the existing power system and controls, and o Installation of batteries for solar power storage on-site. Tesla Portal Facility Interior Floor Slab – The Tesla Portal Facility, a sub-project of the CUW38401 Tesla Treatment Facility, was completed in January 2015. During construction, the concrete interior floor slab was deleted from the project construction documents to allow easier access to repair corrosion of the existing pipelines discovered during construction beneath the new Tesla Portal Facility. Due to drainage issues at the site, the Operations staff at the facility requested the interior slab be incorporated into the structure with a small access opening for future maintenance and corrosion repairs of the existing buried pipelines. This sub-project will be constructed through use of a job order contract including: o A new interior concrete slab slope to drain to a new catch basin, o A new catch basin with grating and sump, and o A small sump pump and drain through the slab or existing concrete wall to a discharge point.
Sunol Valley Region
10015281 Alameda Creek Recapture Project
The planned facilities for this project are based on Alternative 4-1 from the Updated Alternatives Analysis Report (AAR) dated January 30, 2009, with some refinements described below. The planned facilities include the following components: four (4) identical vertical turbine pumps Page 6 of 46 mounted on floating barges located in existing Pond F2 (including a mooring system); four (4) flexible discharge pipelines extending from each pump to a new pipe manifold located on shore; approximately 100-feet of 36-inch pipeline connection between the new pipe manifold and the existing Sunol Pipeline to discharge the recaptured water to the SFPUC system; throttling valves and a flow meter; electrical control building; 1,600 feet of power lines from the existing Hetch Hetchy Water & Power Calaveras Electrical Substation installed on 10 new power poles; and general site improvements. In addition, the scope includes conveyance of the water to various existing storage sites within the Sunol Valley or the Sunol Valley Water Treatment Plant, as necessary.
10015286 Standby Power Facilities - Various Locations
The project consists of installing standby electrical power facilities at five sites in the East Bay and on the Peninsula. Each site is either provided with an emergency generator or electrical receptacles to accommodate a portable emergency generator. The five sites are: Alameda West Portal, and San Antonio A-2
APPENDICES Q1-FY2023-2024 (07/01/23 - 09/30/23)
Reservoir & Dam; Harry Tracy Water Treatment Plant, Millbrae Yard, and San Pedro Valve Lot. 10015290 New Irvington Tunnel
This project consists of an 18,660-foot long tunnel in a horseshoe shape with excavated dimensions of approximately 13 feet by 14 feet. The final tunnel lining will be mortar-lined, welded steel pipe, resulting in a finished diameter of 8.5 feet. Extra thick steel liner segments will also be used at low cover areas near the portals and beneath Interstate 680 where the tunnel intersects inactive fault zones, and where the tunnel passes through areas of poor ground conditions. Major project elements include: • Conventional mining methods are being used in a westward direction from the Alameda West Portal, in both an eastward and westward direction from an intermediate shaft located near Vargas Road just off Interstate 680, and in an eastward direction from Irvington Portal. Tunneling is being completed by multiple road header tunneling machines and limited, controlled detonation in areas of hard rock. Spoils disposal is being taken to fill sites just north of the San Antonio Pump Station (SAPS) near the intersection of Calaveras Road and Interstate 680. When completed the spoils fills will create a visual barrier to a new quarry operation located near Calaveras Road. Potentially contaminated spoils will be screened, separated, and, if found to contain contaminants, hauled to a permitted landfill. • At the Irvington Portal, the tunnel connections to Bay Division Pipelines (BDPL) will include control valves directly buried with instrumentation and electrical gear in a small control building. At the Alameda West Portal, the tunnel will be connected to the discharge of the new mixing manifold to be constructed as part of the Alameda Siphons # 4 Project and to the existing overflow shaft. The project includes a new isolation valve between the mixing manifold and the portal. • The NIT Project will include construction of a new access bridge across Alameda Creek to accommodate temporary construction traffic and on-going SFPUC Alameda West Portal operations. • A Groundwater Management Program has been developed that includes two years of pre-construction monitoring of wells, springs, creeks, ponds, and wetlands; environmental habitat construction mitigation measures; and two years of monitoring after construction to minimize the impact to the local groundwater. • At both the existing Irvington and Alameda West Portal facilities, other security-related site improvements will be constructed, including undergrounding of portal structures and new card access controlled gates and security fences.
10015291 Alameda Siphon #4
Project Description: This project consists of a 66-inch diameter welded steel pipeline; a 96-inch diameter “blending structure” near the Alameda West Portal that will blend SVWTP and Hetch Hetchy water; new isolation/throttling valves on Alameda Siphons Nos. 3 and 4 and new isolation valves on Alameda Siphons Nos. 1 and 2; ventilation improvements at Alameda East Portal; new chemical injection facilities on Siphon No. 4; relocation and extension of the overflow pipe; and road improvements at the intersection with Calaveras Road.
10015312 Pipeline Repair & Readiness Improvements
Project Description: The project consists of three phases for implementation: Phase A (completed) involves the procurement of varied lengths and sizes of welded steel pipe and fitting for stockpiling at seven locations west of the Coast Range Tunnel; Phase B (completed) includes procurement and installation of a pipe rolling facility at the Sunol Yard; Phase C (completed) involves the development of a pipeline repair prioritization plan, on-call emergency repair procedures and contracts, and mutual assistance agreements. 10015317 Calaveras Dam Replacement
Project elements primarily include: • Constructing a new 210-foot-high earth and rock fill dam designed to accommodate a maximum credible earthquake on the Calaveras Fault. The dam will be constructed immediately downstream of the existing dam and will have a crest length of 1,210 feet, a base thickness of A-3
APPENDICES Q1-FY2023-2024 (07/01/23 - 09/30/23)
1,180 feet, and a crest thickness of 80 feet.

LCSD Stilling Basin Modifications & Dissipation Structure Riprap – This sub-project is provided in response to concerns that fish may be “trapped” in the Lower Crystal Springs Dam (LCSD) stilling basin during low flow summer periods, and that high flow discharges from the new LCSD dissipation structure and potential high water levels in Pool 2 may cause erosion of the bank adjacent to the dissipation structure. The dissipation structure includes 60-inch diameter pipes with a maximum flow of 600 cubic feet per second (cfs) each and two 8-inch diameter pipes with maximum flow of 7 cfs each. During flow testing of the dissipation structure, released water could be observed flowing over the dissipation structure, potentially eroding the bank adjacent to the structure. It was also observed that during summer periods, of low flow in the channel downstream of the stilling basin, fish trapped in the basin were dying due to warm water temperatures. The purposes of this sub-project are to hydraulically connect the stilling basin with Pool 2 in order to allow fish to escape the basin in summer, and to add rip-rap behind the dissipation structure to prevent erosion. Specifically, this sub-project consists of: o A new deeper channel between the dissipation structure and the Pool 2, which would prevent fish from being trapped in the stilling basin, o Installation of a new SCADA controls to the existing 8-in discharge pipeline and re-routing one line to the stilling basin, o Installation of additional rip-rap around the dissipation structure, o Installation of a new 24-inch HDPE pipeline through an existing abandoned 60-inch pipe directed to the stilling basin o Coordination and facilitation of access for a piezometer drilling contractor during periods of concurrent work in the stilling basin o Deletion of landscaping around the new Crystal Springs Pump Station o Addition of tree, shrub and grass plantings along the creek bank in accordance with the approved re-vegetation plan. LCSD Valve H53 / Pipeline Investigation & Fisheries Release Valve – As stipulated by the US Army Corps of Engineers 404 permit and the associated biological opinion by NOAA’s National Marine Fisheries Service (NMFS) covering the SFPUC activities at the Crystal Springs Pump Station (CSPS), the SFPUC is to take measures to protect the threatened Central California Coast (CCC) steelhead present in San Mateo Creek at CSPS site. One measure requires the release of fresh water at a rate of 3 to 17 cubic feet per second (cfs) depending on the season in recorded dry and wet years. This sub-project will utilize modification of an existing pipeline to release the required flows to the LCSD stilling basin feeding San Mateo Creek.
Specifically, this sub-project consists of: o Condition assessment of the existing 60-in diameter pipeline from Valve H-53 to the stilling basin. In addition, valve H-53 will be exposed and visually inspected to determine its condition, requiring excavation and shoring of a pit approximately 20 feet long by 20 feet wide by 20 feet deep. o Depending on the verified condition, viable alternatives, including abandonment of the option to use H-53 pipeline, will be evaluated. o The approved option will include a SCADA controlled 12-inch valve installed at the discharge end of the pipeline. Depending on the condition of the pipeline, the approved option may also include repairs to the pipeline lining. Options may also include slip-lining the existing line with a smaller diameter pipeline such as 12 to 24-in diameter flexible polypropylene pipe. o Use of a temporary pipeline “line stop” and associated shoring upstream of Valve H-53 to allow for potential installation of a permanent blind flange. o Replacement of leaking plug valves that discharge from an existing concrete vault to the stilling basin with new knife gate valves. o Installation of new flow control valves, isolation valves and appurtenances for Poo l 2.

10015241 Regional Groundwater Storage and Recovery
The original scope of the Regional Groundwater Storage and Recovery (RGWSR) project was planned to be constructed in two (2) phases. The original scope of Phase 1 included construction of 13 new deep groundwater wells, and the original scope of Phase 2 included construction of 2 to 3 additional wells, depending upon well yield. Based on the modelling data inputs and results, it is projected that the 13 new wells constructed in Phase 1 would produce approximately 6.2 mgd of dry year supply over 7.5 years.
Operating the RGSR Project during times of drought will provide data and insights into how much water can be reasonably expected to be produced by the project and if additional well stations are needed to reach the desired drought period pumping capacity. In addition to the need for collecting operational data to determine the pumping capacity of the 13 new wells, the Daly City Recycled Water Expansion Project proposes to serve recycled water to existing irrigated properties (gold courses and cemeteries) in the Colma area for irrigation use. Replacing groundwater with recycled water for irrigation use will decrease or eliminate the cemeteries’ use of the aquifer, creating more in lieu of storage in the aquifer for water supply use. The SFPUC will identify potential benefits to the aquifer resulting from the Daly City Recycled Water Expansion Project during project planning and design, as well as monitor operation of the project. Given the considerations noted above, the SFPUC modified the scope of Phase 2 in 2018 to install up to three (3) test wells (Ludeman North, Ludeman South, and Centennial Trail), complete the South San Francisco Main well and pipeline, and complete other Phase 1 scope items, including chemical system monitoring, sampling, and storage at various sites. The test wells will allow for determination as to whether the identified sites could be viable production wells, and will provide valuable information related to water quality and potential pumping capacities that can be used for future planning and decision making. The test wells would not be converted to production wells at this time. Proceeding with these changes to Phase 2 will allow all 13 new Phase 1 RGWSR wells to be operated to gain experience and insight into the pumping capacities of each individual well in addition to how the wells work in combination with each other and existing municipal and irrigation wells. Staff will gain valuable experience regarding the relationship of RGWSR drought year pumping to the management of the groundwater basin. Operational experience will allow refinement of the modeled dry year water supply A-13
APPENDICES Q1-FY2023-2024 (07/01/23 - 09/30/23)
of the RGWSR project. The changes to RGWSR Phase 2 also allows for the collection of test well data at up to 3 locations for use in future planning if the operational experience with the 13 wells shows the need for more pumping capacity. This option also allows for the basin effects of the Daly City Recycled Water Expansion Project to be identified and may provide greater flexibility in the future to utilize the basin for water supply. The approved scope for the RGWSR remains the same as approved in April 2018.
However, since 2018 several scope refinements and some additions have been required for successful implementation of the project. Two out of three of the proposed test wells, Ludeman North and Centennial Trail, were installed. The third well, Ludeman South, was not built due to siting and constructability issues. The initial test results from the two test wells indicated that the combined yield of the two wells might be up to 0.6MGD. Based on the relatively low yield from both locations and additional costs required to upsize the Millbrae treatment facility in order to accept and treat these additional flows, it was decided that the test wells would not be converted to production wells at this time. However, these wells will provide valuable information related to water quality and potential pumping capacities that can be used for future planning and decision making.

10015300 System Security Upgrades
Project Description: The purpose of this project is to develop and integrate security components at critical water system facilities including those identified in previous vulnerability assessments and to ensure that security functions such as deterrence, detection, assessment, delay, and response will be effective. As part of this project, SFPUC Security has evaluated all WSIP projects. The project includes the identification of all necessary security components including security fencing, intrusion detection, and vehicle barriers for applicable WSIP projects. The project provides for the necessary planning and design of these facilities, while the individual WSIP projects will fund the installation and construction of civil security work such as conduit layout, fencing, gate installation. This project will however fund the furnishing and installing Access Control and Alarm Monitoring System (ACAMS) and Digital Video Surveillance System (DVSS) equipment, and necessary security systems.
10015334 Programmatic EIR
Project Description: A Program Environmental Impact Report (PEIR) is being prepared for the WSIP under the California Environmental Quality Act (CEQA). The WSIP includes a number of projects that will improve the Regional Water System with respect to water quality, seismic reliability, delivery reliability, and water A-14
APPENDICES Q1-FY2023-2024 (07/01/23 - 09/30/23)
supply. The PEIR will (1) identify and analyze, at a programmatic level, the potential environmental impacts of proposed system improvements, (2) describe and evaluate feasible alternatives to the proposed program, and (3) propose mitigation measures.
10015335 Bioregional Habitat Restoration
2014 Approved Project Long Description: The Bioregional Habitat Restoration project was created to provide a coordinated and consolidated approach to compensate for habitat impacts that may result from implementation of the WSIP projects in the San Joaquin, Sunol Valley, Bay Division, and Peninsula Regions of the SFPUC Regional Water System. The previously approved scope of the Bioregional Habitat Restoration project included projects to preserve, enhance, restore, or create approximately 2,350 acres of tidal marsh, vernal pools, white alder riparian forest, sycamore alluvial woodland, arroyo willow riparian habitat, oak woodland and savannah, sage scrub habitat, serpentine grasslands, coastal live oak woodland, annual grasslands, and oak riparian forest. The project description includes development of compensation sites to preserve, enhance, restore, or create approximately 2,350 acres of tidal marsh, vernal pools, sycamore and oak riparian woodland, oak woodland and savannah, and serpentine and annual grasslands. The project includes design, environmental permitting, construction, construction management, maintenance and performance monitoring during a 3-year plant establishment period. The wide variety of the types of impacts from WSIP projects resulted in the need for development of 18 compensation sites on SFPUC property and contracting with 7 property owners to secure compensation on property outside the Alameda and Peninsula watersheds. There are 7 compensation sites on SFPUC property in the Alameda watershed with an average size of 250 acres, demonstrating a significant commitment to the continued protection of species habitat.
Although the average size of the 11 Peninsula compensation sites is 15 acres, the projects have been strategically placed to best benefit the San Francisco garter snake and the fountain thistle. The increase in habitat compensation addresses the addition of mitigation for the fountain thistle and changes in the Calaveras Dam Replacement Project.
10015336 Vegetation Restoration of WSIP Construction Sites 2014 Project Description: The Vegetation Restoration of WSIP Construction Sites is a WSIP project that received Commission approval on October 9, 2012. This project is required to comply with the CEQA and resource agency permit requirements to restore and re-vegetate habitat areas temporarily impacted by construction at the various WSIP sites to preconstruction condition. 10015337 Long Term Mitigation Endowment
The scope of work and budget for this Long Term Mitigation Endowment was previously included and reported within the WSIP Regional project CUW38802 Bioregional Habitat Restoration; however, the office of the City Controller has established a separate project, specific for this endowment fund in project CUW38804 Long Term Mitigation Endowment. This perpetual endowment fund was required by the United States Army Corps of Engineers and California Department of Fish and Wildlife permits issued for WSIP projects. It provides a secure source of funds for the perpetual monitoring and maintenance of the Bioregional Habitat Restoration sites constructed in the SFPUC watershed.

APPENDICES Q1-FY2023-2024 (07/01/23 - 09/30/23)
The Watershed and Environmental Improvement Program (WEIP) includes the comprehensive identification and protection of critical watershed lands and ecosystem restoration needs within the hydrologic boundaries of the Alameda Creek, Peninsula (San Mateo and Pilarcitos Creeks) and Tuolumne River watersheds, and prioritizes the protection and/or restoration of these lands. Projects under this program will protect source water quality, native species and their habitat; and identify critical watershed lands for protection by purchasing fee title and/or perpetual conservation easements. The program also supports projects that enhance public awareness and provide education opportunities related to water quality, water supply, conservation, and environmental stewardship issues. These projects include construction of the proposed Alameda Creek Watershed Center and improved public access (e.g., trail connections) compatible with watershed management plans and policies.
Initially, specific projects were identified, including the Repair or Replacement of Niles Gage and Watershed Road Management Plan and Improvements – both in the Alameda Creek watershed.
After further research and planning, the program’s focus has shifted towards permanently protecting Alameda Creek watershed lands through conservation easements and/or fee title purchase of property from willing landowners and providing education opportunities that will further the goals of the Water Enterprise Environmental Stewardship Policy. Opportunities that are consistent with the WEIP description and purpose in the Peninsula and Tuolumne watersheds will be considered as well.
