Program Key Updates:
The key updates for the HCIP include:
• For the SJPL Valve and Safe Entry
Improvements project, under Phase 1A
(HH-1005) The valves installed under this
contract that were subsequently rejected
for not meeting performance criteria were
removed under a separate contract; the
team is negotiating a credit. Phase 2A
(HH-1012): The contractor is restoring the
equipment that was flooded at the Roselle
Valve House during the previous quarter in
preparation for upcoming Hetch Hetchy
system shutdown. Phases 2B/2C (HH -
1016): The contractor has started the
outage work and has completed the
excavation for the new removable spool
piece vaults. Phase 3 (HH-1009): The
contractor is preparing to repair an
underground leak that was discovered on a
water sample line; the permanent repair
will be performed during the upcoming
Hetch Hetchy system shutdown.
Newly Excavated Removable Spool Piece Vault
at P4J Crossover Vault
• For the Moccasin Powerhouse Bypass Upgrades project, a revised option to address the previously identified hydraulic concerns was selected by stakeholders. The preferred solution includes a new pipeline from the penstocks to a new pressure dissipation chamber that would be aligned with the existing Moccasin Powerhouse Tailrace at the Moccasin Reservoir shoreline. The redesign includes a new discharge structure that can discharge to the tailrace and also directly to Moccasin Reservoir.
• For Subproject B Moccasin Powerhouse Generator Rewind (DB -121R2) contract, Substantial Completion has been achieved, and the unit has been successfully placed into operation.
Commissioning activities, punch list completion, preparation of operation and maintenance documentation, and other closeout tasks are ongoing. Hetch Hetchy Water and Power has requested the installation of a new vibration monitoring system for both generators to track the performance of the shafts after realignment. For Subproject C, the 95 percent design review has been extended to allow additional time to address design criteria comments and coordinate construction sequencing and outage.
• For Transmission Line Clearance Mitigation project, the Progressive Design-Build contract DB- 139R will be re-bid in early 2026. The project team is currently finalizing the CEQA Common Sense Exemption (CSE), which will be included in the contract re-bid.
iii Executive Summary | HCIP Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25)
• For the Warnerville Substation
Rehabilitation project, the Subproject B
construction contract (Phase 2 – HH-1017)
has received Notice-to-Proceed with
construction underway.
Warnerville Substation – New Switches
• For the Moccasin Penstock Rehabilitation, revised alternatives will be re -evaluated due to changes to Right of Way assumptions and additional information regarding Operability, Constructability, Cost, and Schedule for each alternative.
• For the Moccasin Engineering & Records Building 65% Construction Drawings are complete; design team is progressing toward 95% while addressing comments. Scope, schedule, and budget for water pressure reduction equipment are being developed; potential schedule and budget impacts are under review.
• For the Moccasin Warehouse Building project, the design team is advancing the Schematic Design package with review comments. HHWP’s warehouse size increase has caused a cost variance.
The project is now forecasted to finish one year earlier than baseline due to early scope refinement and funding reallocation supporting an accelerated timeline. • For the O’Shaughnessy Dam Outlet Works Phase 1 Subproject A (contract DB -135 for bulkheads rehabilitation), is in closeout and received the 2025 San Francisco Collaborative Partnering Award.
For Subproject B (contract HH -1015 Drainage & Miscellaneous Dam Improvements), construction is progressing, with drain cleaning complete and ladder wells operational; remaining installations are scheduled next quarter.
• For the Moccasin Dam & Reservoir Long-Term Improvements project, the SF Board of Supervisors approved the amendment to the design contract. Procurement is underway for a Construction Manager/General Contractor (CM/GC) collaborative delivery construction contract. The project schedule may be reduced by approximately 18 months due to a shorter environmental review process.
• For the Cherry Dam Spillway - Short Term Improvements project, the construction contract was combined with work for the Eleanor Dam Interim Bridge Repair and was advertised in December 2025; three bids were received. The project team is in the process of evaluating the bids received and moving towards a recommendation.
• For the Eleanor Dam Rehabilitation and the Interim Bridge Repair subproject, the work for Interim Bridge Repair is combined in the same construction contract with Cherry Dam Spillway - Short Term Improvement. The contract was advertised in December 2025, and three bids were received; the project team is in the process of evaluating the bids to provide a recommendation for

INTRODUCTION
The Hetch Hetchy Water and Power Division under the Water Enterprise (HHWP) is responsible for managing, operating, and maintaining water facilities that are part of the Regional Water System from Hetch Hetchy Reservoir, located in Yosemite National Park, to Alameda East Portal, located in Sunol Valley, and power facilities located from Early Intake Reservoir along the Tuolumne River to the city of Newark. HHWP facilities include three impoundment reservoirs, three regulating reservoirs, four powerhouses, one switchyard, three substations, 170 miles of pipeline and tunnels, almost 50 miles of paved road, over 160 miles of power transmission lines, watershed lands, and right- of-way properties.
HHWP provides 85 percent of the San Francisco Public Utilities Commission (SFPUC) water supply for
2.7 million residential, commercial, and industrial customers in Alameda, Santa Clara, San Mateo, and San Francisco counties. On average, HHWP generates about 1,650 gigawatt hours (GWH) of clean hydro-generated power annually. A majority of HHWP staff is based in Moccasin, CA, which is 140 miles east of San Francisco.
This report provides a quarterly status update on the Hetch Hetchy Capital Improvement Program (HCIP), a group of capital improvement projects that are greater than $5M in value and have been approved by the Commission as part of the SFPUC’s 10-Year Capital Improvement Program. The status of the Hetch Hetchy R&R projects and other programmatic projects not included in the HCIP is reported annually in the Annual Report on Water Enterprise-Managed Capital Improvement Projects.
The map below shows the location of the assets and facilities associated with HHWP.

This page is intentionally left blank
1 H CIP Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) SECTION 1. PROGRAM DESCRIPTION
The Hetch Hetchy Capital Improvement Program (HCIP) is a group of multi -year capital projects to upgrade existing, aging infrastructure so that it will meet the challenges of today and the future. These projects will deliver improvements that enhance the SFPUC’s ability to provide reliable, affordable, high-quality water to its 2.7 million customers in an environmentally sustainable manner. The goals are 1) to provide capital improvements needed to cost-effectively ensure that water quality, seismic reliability, delivery reliability, and water supply objectives established for the Regional Water System facilities managed by HHWP are met, and 2) to optimize the benefits of HHWP power facilities operations. Ongoing development of the HCIP will sustain the Regional Water System’s status as an unfiltered water source and a gravity-driven system.
The scope of HCIP is divided into three major project types: Water, Power, and Joint. The Water sub- program includes only asset improvements that benefit the SFPUC’s water customers. The Power sub- program includes only asset improvements used to generate environmentally friendly hydroelectric energy. The Joint sub-program includes projects for assets that are used for both water delivery and power generation. In addition, projects in each sub-program of the HCIP have been further organized by asset type consisting of the following:
Water Infrastructure
• Water Conveyance – projects to enhance the reliability of water delivery through pipelines and tunnels, allowing for delivery of water to SFPUC customers. • Water-Only Facilities – p rojects that benefit water delivery (but not power production) such as water quality protection and improvement projects.
Power Infrastructure
• Powerhouse – projects to improve facilities at the Holm, Kirkwood, and Moccasin powerhouses.
• Switchyard & Substations – projects to meet operational objectives for power, including reliability, regulatory compliance, and sustainability. • Transmission Lines – projects to expand or improve power assets for electricity transmission.
• Power-Only Facilities – o ther projects that benefit power production and transmission (but not water) such as Cherry-Eleanor Pump Station.
Joint (Water and Power) Infrastructure
• Dams & Reservoirs – projects to improve assets used for storage and delivery of water to SFPUC customers, as well as for water storage for power generation. • Mountain Tunnel – projects to address deficiencies with the Mountain Tunnel, a critical, non- redundant link in the Hetch Hetchy and Regional Water System that conveys water from Kirkwood Powerhouse to Priest Reservoir.
• Roads & Bridges – projects to replace or improve roads and bridges that are utilized to access HHWP assets.
• Utilities – projects to expand or improve utilities for asset and work locations such as water and wastewater treatment facilities.
• Buildings – projects to provide safe and code compliant workspaces.
2 HCIP Quarterly Report | Q2-FY2025-2026 (10/01/25–12/31/25) SECTION 2. PROGRAM STATUS
This Quarterly Report presents the progress made on HCIP between October 1, 2025 and December 31, 2025. This document serves as the second Quarterly Report in Fiscal Year 2025-2026 (FY26) published for the HCIP.
This quarterly report includes all HCIP projects in the Hetch Hetchy Water Capital Improvement Program according to the 10-Year Capital Plan for FY2024-25 to FY2033-34 (FY25-34 CIP), presented to and adopted by the Commission on February 13, 2024, under Resolution No. 24-0032 (2024 HCIP). The 2024 HCIP is a subset of the Hetch Hetchy Water 10-Year CIP for FY2025-2034 and includes individual projects over $5 million that were then currently active or intended to be active by July 1, 2024 at the time proposed to the Commission on February 13, 2024. This baseline for comparison will remain the same until adoption of a new 10 -Year CIP; the baseline will be updated with the changes in the adopted CIP at the start of the new fiscal year following adoption. As part of the mid-cycle update to the 10-Year Capital Plan for FY2025-26 to FY2034-35 that was adopted by the Commission on February 11, 2025, none of the 22 HCIP project budgets or schedules were changed from the 2024 HCIP.
There are 22 projects in the 2024 HCIP together with three project development (PD) accounts for program-level expenditures for each of the Water, Power, and Joint Programs. A description of each project and of each project development account is provided in the Appendix A of this report.
The accrued PD expenditures are included in the Cost Summary in Table 3 in order to give an accurate report of the overall HCIP cost performance.
Table 2.1 below shows the number of projects and total project value in each phase of the program based on the Current Approved Budget for all 22 projects as of December 31, 2025 (PD accounts do not have phases and are not included in Table 2.1).

Current Phase: Design Environmental Status: Active (Cat Ex)
Progress and Status:
The consultant design team presented to stakeholders three possible solutions to address the previously identified hydraulic concerns, each with associated cost and schedule impacts. Stakeholders selected a preferred solution which removes all open channel flow through box culverts and instead conveys water through a pipeline from the penstocks to a new pressure dissipation valve house that aligns with the existing Moccasin Powerhouse at the Moccasin Reservoir. The redesign includes a new dissipation chamber and discharge structure downstream of the valve house in the reservoir.
Issues and Challenges:
The redesign required that the design team start again at the conceptual engineering design phase before developing bid documents for review. This has added 10 months to the design phase of the project. The scope of the redesign is estimated to increase the project construction duration by 6 months, extending the construction period to 24 months. The scope of the redesign includes two new facility structures, more high- pressure pipe materials and additional construction scope including the dissipation chamber and the discharge structure at the reservoir, two 48- inch diameter high pressure steel pipelines from the penstocks to the Moccasin Powerhouse, deep excavation between the existing powerhouses, and mitigation for construction occurring below the reservoir surface level. Each of these components added significant cost to the project budget increasing the cost by close to two times. The project cost and schedule impacts associated with this redesign have been reflected in the forecast and included in the upcoming Capital Improvement Plan.

Expenditures to Date: $57.80M Expenditures Over the
Reporting Period:
$1.34M
Current Phase: Multi-Phases Environmental Status: Completed (Cat Ex)
Progress and Status:
Subproject A – Moccasin Powerhouse Generator Step -Up (GSU) Transformers: Project closeout activities for Contract HH -1003R have been completed. Subproject B – Moccasin Powerhouse Generator Rewind (DB -121R2): Substantial Completion has been achieved, and the unit has been successfully placed into operation. Commissioning activities, punch list completion, preparation of operation and maintenance documentation, and other closeout tasks are ongoing. Hetch Hetchy Water and Power has requested the installation of a new vibration monitoring system for both generators to track the performance of the shafts after realignment. An existing vibration monitoring system previously installed by GE will be rented for interim use until a permanent system is procured. Final Completion for Subproject B may be extended until delivery of the new vibration monitoring equipment. Subproject C – Moccasin Powerhouse Systems Upgrade: The 95 percent design review has been extended to allow additional time to address design criteria comments and coordinate construction sequencing and outage.
Issues and Challenges:
The variance between the approved budget and forecasted cost is due to increased cost contingency of the DB-121R2 contract for the new fire suppression system and solutions to address Unit M1 alignment, as well as forecasted cost increases in Subproject C – Systems Upgrade, where higher costs are anticipated from scope refinement, higher construction and procurement costs, and additional construction management and support resource requirements. The schedule change is a result of the delay in the design schedule due to project complexity as well as delay to the Moccasin Bypass Upgrades project. Construction for that project must be completed before physical work inside the powerhouse and outages for Subproject C can begin. The proje ct’s forecasted cost and schedule have been included in the upcoming Capital Improvement Plan.

13 10039568 - Moccasin Switchyard Rehabilitation
Approved Budget: $19.71M Approved Completion Date: 01/31/30 Forecast Cost: $32.75M Forecast Completion Date: 08/12/31 Cost Variance: ($13.04M) Schedule Variance: -558 days
Expenditures to Date: $0.82M Expenditures Over the
Reporting Period:
($0.02M)
Current Phase: Planning Environmental Status: Not Initiated (TBD)
Progress and Status:
Needs Assessment Report (NAR) with proposed scope changes has been submitted and is under review. The Alternative Analysis Report (AAR) will commence upon approval of NAR. Following finalization of the NAR, the project team elected to include “Greenfield” as an additional alternative. The Greenfield alternative would propose constructing a new switchyard in an alternative site location. This decision necessitates supplemental field investigations, including surveying, potholing, hazardous material, and geotechnical borings.
Issues and Challenges:
The variance in schedule is due to the need to have project work commence after completion of the Moccasin Powerhouse Bypass project, which is forecasted to reach completion in May 2030. Moccasin Powerhouse Upgrade project is also scheduled to start construction phase concurrent with Switchyard project. If “Greenfield” option is not selected, construction activities of 2 projects in vicinity of Powerhouse may be overcrowding the area. The variance in pre- construction schedule is due to the addition of Greenfield as an alternative requiring additional field investigation, survey, potholing, hazardous material, and geotechnical boring. The variance in budget is due to estimate of construction costs at NAR phase and escalation costs for electrical equipment and labor. The project’s forecasted cost and schedule have been included in the upcoming Capital Improvement Plan.

Current Phase: Planning Environmental Status: Active (Cat Ex)
Progress and Status:
The design team is incorporating the review comments from the Conceptual Design package into the Schematic Design package.
Issues and Challenges:
As reported last quarter, the project is currently experiencing a cost variance due to a requested increase in warehouse building size from approximately 9,000 square feet to 15,000– 20,000 square feet, as directed by HHWP to consolidate storage from multiple campus locations. This scope increase has resulted in forecasted costs exceeding the approved budget. The project is also showing a schedule variance, with the forecasted completion date approximately one year earlier than the approved baseline. This acceleration is attributable to early scope refinement and the recommended reallocation of funding to support an expedited delivery approach. The forecasted cost and schedule have been included in the upcoming Capital Improvement Plan.

Current Phase: Bid and Award Environmental Status: Active (MND)
Progress and Status:
The construction contract for the project (combined with Eleanor Dam Interim Bridge Repairs subproject) was advertised in December 2025 and three bids were received. The project team is in the process of evaluating the bids. The project team addressed the comments on the preliminary Mitigated Negative Declaration (MND) and issued the final MND in December 2025. The HHWP Vegetation Crew will perform tree cutting at the spillway between January and February 2026, ahead of bird nesting season.
Issues and Challenges:
As previously reported, the cost and schedule variance are due to scope refinement identified during the 65% design review, which concluded that additional excavation and armoring of the upper spillway are required to meet project objectives and regulatory performance criteria. These scope additions resulted in increased construction costs and associated soft cost impacts, increasing the total project cost forecast. The revised scope also extended the construction duration, with substantial completion now forecasted for July 2027. Project cost and schedule forecasts have been updated to reflect these changes and are incorporated into the upcoming Capital Improvement Plan.

APPENDIX A. PROJECT DESCRIPTION
Water Infrastructure
Water Conveyance (Water)
10035575 SJPL Valve and Safe Entry Improvement
San Joaquin Pipeline (SJPL) Nos. 1, 2, and 3 consist of three parallel transmission pipelines (completed in 1932, 1953, and 1968, respectively) that cross the San Joaquin Valley from the east of Foothill Tunnel at Oakdale Portal to the west of Coast Range Tunnel at Tesla Portal, a distance of approximately 48 miles. A fourth partial pipeline (SJPL 4 completed in 2012) consists of a 6.4- mile segment of pipe downstream of Oakdale and another 11- mile segment upstream of Tesla Portal.
SJPLs deliver Tuolumne River water to the San Francisco Bay Area. They have been in service ranging from 11 to 91 years. SFPUC staff members and contractors need to enter the pipelines regularly to perform condition assessment, maintenance, and repair work. A recent hydraulic study shows that several of the existing valves in the SJPLs may be under -rated for the potential surge pressures that could be triggered from an unplanned closure of the valves at the downstream Tesla Ultraviolet Treatment Facility. For safety reasons, the SFPUC initiated this capital project to increase the pressure rating of the valves, provide safe pipeline isolations for personnel entry into the pipelines, and allow shutdown of any section of the SJPLs without a complete system shutdown.

Joint Infrastructure
Water Conveyance (Joint)
10014088 Moccasin Penstock Rehabilitation
In order to meet the established level of service, mitigate potential risks, and avoid potential consequences of failure, SFPUC is considering replacing the penstocks so that the life of the asset will be extended for another 75 to 100 years. Based on a preliminary study, a combination of a drop shaft, a tunnel and above grade pipes appears to be a favorable alternative. SFPUC will continue the study before determining the most appropriate alternative solution. For capital planning purposes, SFPUC assumes the alternative will include the following major elements: • A drop shaft of about 850 feet deep, • A new tunnel penstock of about 3,100 feet, and • A two 72 in. above- grade penstocks with a total length of 3,000 feet
Buildings (Joint)
10039680 Moccasin Engineering and Records Building
HHWP Project operations and administration is located in Moccasin, California, with facilities including buildings, office trailers, warehouses, shops, laboratories, and sheds. Many existing facilities are deteriorating, do not meet current building codes, and are incurring increased maintenance costs. HHWP needs to invest in new facilities to meet all applicable codes and standards; reduce maintenance costs; increase employee interconnectivity and productivity; properly store all staff, materials, records, and equipment; and meet energy -efficiency standards. HHWP prepared a report titled "Moccasin Facilities Upgrade Project – Alternatives Analysis and Evaluation Report Update". The report identified long- term needs for creating adequate office space for current staff in Moccasin. In addition, the report evaluated the needs for new, dedicated materials storage space, new records and archives space with offices, new space for servers, and parking space for staff. The Moccasin Engineering and Records Building project will address the need for permanent office space by constructing a new two- story building. Hetch Hetchy and Infrastructure staff are currently located in temporary trailers that have exceeded their useful life. The new building will provide office space for Hetch Hetchy Engineering, Records, Energy Services, Infrastructure, and ITS staff. The scope also includes a secure server room, parking lot, and archive/records storage.
The budget and schedule for the project will be modified to provide permanent office space for both Hetch Hetchy and Infrastructure staff and to address escalation since the completion of the 2020 Alternatives Analysis Report estimate.
10041727 Moccasin Warehouse Building
The Moccasin Old Powerhouse was constructed in 1926 and abandoned in the 1960s. The building has multiple structural and nonstructural issues, including cracks, spalling of structural concrete, water intrusion, broken windows, settlement, hazardous materials, and seismic deficiencies. The building is currently used for storage of large equipment and critical spares for the Hetch Hetchy

Water and Power system. As a result of the multiple issues, it was determined to demolish the building. A new warehouse is therefore necessary for the storage of the large equipment and critical spares for the Hetch Hetchy Water and Power system that was previously stored in the Moccasin Old Powerhouse. This project includes a construction of a new 9,000-square- foot warehouse within the Moccasin campus to store large equipment and critical spare components for the Hetch Hetchy Water and Power System. The bu ilding will include office space for warehouse staff including records retention for warehouse and materials documentation.
Dams & Reservoirs (Joint)
10032903 O'Shaughnessy Dam Outlet Works Phase 1
O'Shaughnessy Dam was completed in 1923 and raised in 1938. A condition assessment of the dam outlet works revealed the need for improvements to the existing outlet works, including gates and valves (1923 construction), to ensure safe and reliable operation. Based on engineering studies and prioritization of asset condition, needs, and risks, improvements to the existing outlet works will be implemented in two phases. Funding for this project will include work under Phase 1. Phase 2 of the O'Shaughnessy Dam Outlet Improvement Project begins in 2025. Work under Phase 1 will include:
(1) replacement of two existing instream flow release valves; (2) improvements to access and drainage in the dam gallery and stairs; (3) installation of new bulkheads for the outlet intake; and (4) a planning phase and scoping for the slide gates and drum gates improvements. 10037351 Moccasin Dam & Reservoir Long Term Improvement A heavy storm event in 2018 caused significant damage to the auxiliary spillway, upstream trash rack and diversion, and downstream area. Subsequent engineering studies concluded that improvements are needed to increase the spillway capacity to safely pass the updated design flood without overtopping the existing embankment dam. This project is needed for dam safety. This project will construct a new concrete spillway with adequate flow capacity along the alignment of the existing auxiliary spillway and additional flood protection to the Moccasin project facilities. 10014115 Cherry Dam Spillway - Short Term Improvements
Cherry Dam Spillway is a 334 -foot-wide ogee -type concrete weir that discharges into an unlined adjacent channel. The spillway capacity is designed for 52,000 cfs. A spill of 1,500 cfs in 2010 resulted in significant erosion damage to the unlined spill channel, large- scale erosion along the western segment of Cherry Dam, and flooding of Cherry Power Tunnel Adit and a campground downstream. Engineering studies showed that remedial measures and erosion protection for the spill channel are needed to ensure that spill flows from Cherry Vall ey Dam spillway can be contained without erosion damage to the existing embankment dam and downstream area. Studies also found that long- term improvement to the spillway is needed to increase the hydraulic capacity of the spillway to safely pass the design flood. This project is a short-term interim solution until the long- term spillway improvements are implemented. This project will reestablish containment for the breached spill channel section from the 2010 spill and install armoring to protect the upper spill channel section against erosion from spillway releases of up to 2,000 cubic feet per second. 10030759 Eleanor Dam Rehabilitation
Mitigation alternatives will include improvements to increase spill capacity to safely pass the design flood, installation of a liner on the upstream face of the dam, concrete repairs, valve replacement, and installation of concrete lining and riprap for foundation armoring, and replacement of the existing bridge.

10039119 Early Intake Dam - Long Term
Remove the existing deteriorated dam and construct a new concrete diversion structure and conveyance system within the existing Raker Act boundary to divert flows from Cherry Creek and Tuolumne River upstream of Kirkwood Powerhouse into Mountain Tunnel for SFPUC customers during emergencies.
Mountain Tunnel
10014114 Mountain Tunnel Improvement Project
Constructed between 1917 and 1925, Mountain Tunnel (MT) is a critical, nonredundant link in the Hetch Hetchy Regional Water System, conveying SFPUC water supply from Kirkwood Powerhouse to Priest Reservoir. Due to the tunnel's 90 years of operation, deferred maintenance, and construction deficiencies from the early 1900s, sections of the tunnel have deteriorated, some more extensively than others. The Mountain Tunnel Inspection and Repairs Project provided a tunnel inspection in 2017 to update the Condition Assessment conducted in 2008. Short- term repairs were also made in 2017 and 2018 to reduce the risk of failures in the concrete lining prior to implementation of the long- term project. The Mountain Tunnel Improvements (Rehabilitation)Project was selected for the design and construction of the preferred engineering alternative that will keep this vital component of the Hetch Hetchy Regional Water System in reliable service for years to come. The budget and schedule are based on the Mountain Tunnel Improvements Project construction phase, which is anticipated to take place between 2021 and 2027. This is the water funded portion of the Mountain Tunnel projects. For t he Mountain Tunnel Improvements Project, the water portion will rehabilitate the inside of the tunnel and extend the siphon at South Fork, along with related safety improvements to the roadways that access the Mountain Tunnel.
CUH102-N03 O'Shaughnessy Dam Outlet Works Phase 2
O'Shaughnessy Dam was completed in 1923 and raised in 1938. A condition assessment of the dam outlet works revealed the need for improvements to the existing outlet works, including gates and valves (1923 construction), to ensure safe and reliable operation. Based on engineering studies and prioritization of asset condition, needs, and risks, improvements to the existing outlet works will be implemented in two phases. The O'Shaughnessy Dam Outlet Works Phase 1 Project is described under Project Number 10032 903 and is currently in the design and construction phases. Phase 2 of the O'Shaughnessy Dam Outlet Improvement Project will begin in 2025 and will include replacement and/or refurbishment of eight discharge valves, rehabilitation of three drum gates, refurbishment of twelve slide gates, installation of a new diversion pipe isolation valve, and improvements for the diversion tunnel. The project will include: (1) replacement of six 60-inch and one 72- inch discharge needle valves; (2) refurbishment of one 72- inch discharge butterfly valve; (3) rehabilitation of three drum gates; (4) refurbishment of twelve slide gates; (5) installation of a new diversion pipe isolation valve; and (6) improvements for the diversion tunnel.
