Fiscal Year: 2024-25
Organization: HHP1002 - HHP10 Hetchy Water (298646)
Proposal: 27 - Physical Security Program
Fund/Dept/Auth/Proj/Act: 24970/298646/10000/10029992/0022 Security threats to utilities are real and constantly evolving. Over the last three years there has been a notable increase in physical attacks on critical Infrastructure, from domestic terrorists, to violent extremists, and lone wolf attacks. In addition, these attacks have increased in sophistication and destructive potential, in both the ability to deliver an attack and to cause cascading long- term effects. Additionally, current supply chain shortfalls continue to plague security components availability, and costs continue to dramatically increase. Delayed security projects only increase in costs year over year and make HHWP more vulnerable. Finally, recent federal site inspections (through the Bureau of Reclamation (BOR)) have identified multiple areas for improvement to increase
HHWP’s
Critical
Infrastructure
Protection
and
Resilience
-
with
specific
focus
in
and
around
O’Shaughnessy
Dam.

To address a variety of ever-increasing threat streams, ensure reliable levels of service for our customers, as well as meet State and federal regulations Hetch Hetchy Water (HHW) requires improvements to our overall security posture outlined in this proposal. These improvements will increase the integration of cyber and physical security systems, create a multi-layered security stance, and increase overall system reliability (physically controlling access to cyber assets is the number one way to prevent cyber-attacks). These improvements will require the procurement of additional
hardware,
software,
and
service
solutions.

Physical security hardware and software procurement will focus on modernization and further proliferation of access control systems and intrusion detection equipment (such as Lenel and Cyber Key integrated surveillance systems). These system improvements will be focused on enhancing security at critical infrastructure, facilities, and other assets identified by SFPUC security plans, and

Fiscal Year: 2024-25
Organization: HHP1002 - HHP10 Hetchy Water (298646)
Proposal: 29 - Native American Cultural Resources Mgmt Pilot Program Fund/Dept/Auth/Proj/Act: 24970/298646/10000/10029992/0022 The Water Enterprise (WE) includes two divisions: Hetch Hetchy Water (HHW) and Natural Resources and Lands Management (NRLM). HHW operates and maintains the Hetch Hetchy Water & Power (HHWP) System, with infrastructure that spans nearly the entire width of the state of California and transects the traditional tribal homelands of many Native American tribes and groups.

The Planning and Compliance Section of the NRLM is responsible for supporting HHW operations in maintaining environmental compliance and continued implementation of the Water Enterprise's Environmental
Stewardship
Policy.

The WE has a history of focused, project-specific outreach and consultation with Native American Tribes as required by California law. Outside of these efforts, a consistent relationship and dialogue with traditionally affiliated tribes and groups in the Hetch Hetchy region has not yet developed. In 2022, on behalf of HHW, NRLM submitted a Sacred Lands File search request to the Native American Heritage Council (NAHC); the search result was positive, and the NAHC returned a list of 27 separate Native American tribes that are traditionally and culturally affiliated with the geographic area of the HHWP system. Despite this large number of traditionally and culturally affiliated tribes and groups, the ethnographic history of the HHWP territory is largely unknown. As the needs of the WE and affiliated tribes evolve over the coming decades, more regular and meaningful dialogue about our work on Native homelands would benefit all stakeholders; this ongoing dialogue
will
be
the
foundation
of
building
relationships
based
on
mutual
respect
and
reciprocity.

At present, HHW and NRLM co-manage over 160 known archeological sites intersected by HHWP system infrastructure and operations; many are managed in collaboration with federal partners, including the National Park Service in Yosemite, the Stanislaus National Forest, and the Bureau of Lands Management. Approximately half of the HHWP system land base does not have comprehensive or modern archeological survey coverage. Given this data gap, it is highly probable that many additional archeological sites exist in this territory that have not yet been identified.

We
seek
to
address
this
deficiency
by
performing
a
property-wide
archeological
records
search,
and
analysis
of
archeologically

sensitive
areas
where
additional
survey
is
needed.

The Water Enterprise employs approximately 900 employees. The NRLM division has 130 employees focused on natural resources and lands management, including 34 biologists, 4 hydrologists, and 2 watershed foresters. The Moccasin/Tuolumne NRLM team that supports HHW across their vast territory has three environmental planners, one full-time biologist, two half-time biologists, and one half-time watershed forester. There are no positions within NRLM dedicated to cultural resources management and tribal engagement. Presently, tribal engagement is overseen by two key
employees
within
NRLM
that
hold
these
key
relationships
as
collateral
duty.

The WE maintains unique stakeholder relationships across a vast geographic footprint where maintenance and infrastructure needs are constantly developing. Allocating a dedicated staff resource to oversee Native American engagement and cultural resource management would provide a continuum for communication with interested Native American tribes and groups; having this
dedicated
liaison
would
benefit
project
development
and
the
WE’s
relationship
with
stakeholders
over
the
long-term.

While the Water Enterprise's Environmental Stewardship Policy is a proactive stewardship mandate focused on ensuring the resources entrusted to our care area protected, it does not specifically speak to Native American, tribal, or cultural resources. However, the proposed amendments to the SFPUC’s Level of Service Goals and Objectives specifically call out the Enterprise priority to expand targeted, thoughtful efforts to build relationships with Federally Recognized Tribes and other California Native Americans, and to manage watershed and right of way lands to protect cultural
and
tribal
resources.

Finally,
the
SFPUC’s
Racial
Equity
Action
Plan
(REAP)
says:

“As
an
agency
utilizing
unceded
Indigenous
lands,
we
have
a
responsibility
to
educate
ourselves,
our
employees,
and
the
public
about
California’s
Indigenous
peoples,
past
and
present.”

This
pilot
program
furthers
strategic
program
areas
from
the
REAP;
specifically,
it
will
help:

•
Strengthen
recruitment
and
hiring
strategies
to
attract
and
cultivate
diverse
candidates
at
all
levels
of
the
department.

•
Ensure
salaries
and
benefits
allow
for
a
dignified
livelihood,
especially
for
people
of
color
and
women.

•
Commit
to
developing
a
diverse
and
equitable
leadership
that
will
foster
a
culture
of
inclusion
and
belonging.

•
Ensure
staff
needs
are
centered
and
timely
met
in
order
to
perform
and
excel
at
their
jobs.

•
Foster
an
intentional
organizational
culture
that
is
committed
to
inclusion
and
belonging.

•
Develop
internal
communication
processes
and
procedures
that
promote
equity.

•
Expand
the
internal
culture
of
belonging
by
fostering
relationships
with
the
external
communities
the

serves.

Project Manager: Blake Rothfuss Current Active Phase: Construction Prior Approved Budget: $ 59,229,538 Proposed Budget: $ 82,229,538 Prior Approved Start: 07/01/2019 Proposed Start: 07/01/2019 Prior Approved Finish: 06/30/2033 Proposed Finish: 06/30/2034 Description
SCOPE: Deliver capital improvement projects to sustain the reliability of the nearly 50 mile-long San Joaquin Pipeline (SJPL) System, which conveys water from HHWP's Oakdale Portal to Tesla Valve House.

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets prior to wholesale replacement. It is expected that the program will be able to delay the need for planned large-scale replacement for 20 to 60 years, depending on type of pipe, conditions, valves and operators, instrumentation and control obsolescence, cyber security evolution, environmental factors, and initial installation practices. HHWP's SJPL R&R Program will extend the life of the asset through renewal/replacement, which will constitute betterments to the asset. Typical activities include inspection, condition assessment, design, construction when appropriate, lining and coating replacement, anti-corrosion systems installation, flowmeter and dedicated power upgrades, physical and cyber security, betterments to address regulatory compliance issues, and other life extension activities that meet fixed asset definitions and criteria.

ASSETS: Represented asset families include Oakdale Portal, valve houses, and stand-pipes; SJPL No's. 1, 2, 3 and 4; throttling stations; Emery Crossovers; Roselle Crossovers; Pelican Crossovers; San Joaquin Valve House; Tesla Valve House; corrosion and condition monitoring systems; regulating and control valves; generators, solar panels/inverters/batteries, flowmeters, and other power supplies; instrumentation and controls; all access points; SCADA; and all ancillary equipment.

Justification
The SJPL system was constructed over time between 1931 and 2012, with most assets constructed during 1931 through 1969. Recent and ongoing pipeline condition assessments indicate the potential for decreased reliability and the need for continued renewal and replacement of the pipelines.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Pipeline failures/leaks can interrupt water deliveries. Unanticipated failures can result in increased emergency repair costs, and potentially significant property damage

Facility Category: Water Infrastructure
Project Manager: Jimmy Leong Current Active Phase: Construction Prior Approved Budget: $ 140,661,975 Proposed Budget: $ 157,752,191 Prior Approved Start: 07/01/2019 Proposed Start: 07/01/2019 Prior Approved Finish: 03/13/2028 Proposed Finish: 02/28/2029 Description
SCOPE: Provide safe entry into the SJPL System, in compliance with SFPUC Safe Pipeline Isolation procedure, to support future inspection, maintenance and capital improvements of SJPL system. The scope includes the following:
• Replacement of Valves TUV 201 through 401 at Tesla Portal • Installation of double knife gate valves at Emery, Roselle, and Pelican Crossovers. • Building new Removable Spool Pieces (RSPs) along the pipelines. • Building a new Surge Tower at Tesla Portal.

PROJECT DESCRIPTION: 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.

ASSETS: Butterfly valves at Tesla Valvehouse (TUV201 through 401), Oakdale Portal, Emery Crossover, Roselle Crossover, and Pelican Crossover and associated actuators; removable spool pieces at each location for each line; knife gate valves at each crossover location.

Justification
This project will improve safe entry into the SJPL System, in compliance with the SFPUC Safe Pipeline Isolation procedure.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
If the proposed work is not implemented, then SJPL cannot be safely isolated and accessed for inspection, maintenance, rehabilitation, and/or replacement without shutting down the entire SJPL System.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The increase in budget is partly due to escalation and partly due to additional scope in Phase 3. The additional scope in Phase 3 Tesla Surge Tower includes 1) a recirculation system to prevent stagnant water in the surge tower and 2) replacement of the existing spillway concrete chute as structural integrity of the wall and slab have been compromised due to erosion.

SCOPE: 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.

PROJECT DESCRIPTION: For the 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.

ASSETS: Mountain Tunnel
Justification
A catastrophic failure is possible with continued tunnel lining degradation. The likely type of anticipated failures are "local collapses," which would not impact power generation but would create water quality events in terms of turbidity in the water supply. The likelihood of localized collapses is moderate to high. Depending on the configuration of the system, this type of event could interrupt the deliveries from the Tuolumne River to the Regional Water System.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Depending on the configuration of the system, a "local collapse" could interrupt delivery of Tuolumne River to the SFPUC water customers.

Continual degradation of the asset could lead to a catastrophic failure.

Budget Change Yes Schedule Change No Scope Change No
Reason for Change
The change in budget is a result of increased costs associated with South Fork construction, construction management services, and site security.

SCOPE: Provide remote supervisory monitoring and control over SJPL System, including in-line and cross-over valves.

PROJECT DESCRIPTION: Design, procure, and construct new SJPL remote supervisory controls that would enable remote operation from Moccasin to remotely operate valve actuators. The project includes data telemetry improvements, Remote Terminal Unit (RTU) installation/replacement, trans-valley communication system upgrades, power system upgrades, security improvements, and access improvements.

ASSETS: Represented asset families include Oakdale Portal, valve houses, and stand-pipes; San Joaquin Pipelines Nos. 1, 2, 3, and 4; throttling stations; Emery Crossovers; Roselle Crossovers; Pelican Crossovers; San Joaquin Valve House; Tesla Valve House; regulating and control valves, and actuators; generators and power; instrumentation and controls; and SCADA.

Justification
Pipeline assets were first placed into service in 1931 and vary in age from 10 to more than 90 years old. Three 50 mile-long pipelines cross San Joaquin Valley; a fourth pipeline crosses 17 miles of the valley. All the valves on SJPL are controlled locally, requiring field staff to travel up to 2 hours to reach the valves and operate them. Remote control will allow for valves to be closed remotely, from the Moccasin Control Center, reducing damage in the event of a pipeline failure.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
In the event of pipeline section failure or major leak, field staff must first locate the failure and travel up to 2 hours to close valves to reroute water around the failed pipe section. During this time period, significant water could be released under pressure. Delayed valve closures to isolate major leaks increase third-party and CCSF property damages.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The change in budget and scope is a result of expanding the project to cover all 120 valves along the SJPL system. The decrease in schedule is a result of evaluating the level of effort to complete the scope.

SCOPE: Deliver capital improvement projects to sustain the reliability of water conveyance assets that are power funded. The R&R Water Conveyance Life Extension (water and joint) and the SJPL Life Extension Project address reliability improvements for other segments of the Hetch Hetchy Regional Water System.

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets prior to wholesale replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction when appropriate to sustain the reliability of power funded, water conveyance assets with capital improvements. Water is conveyed from upcountry reservoirs to hydroelectric powerhouses via a network of tunnels, pipelines, penstocks, and canals, through valves, gates, portals, penstocks, and reservoir bypasses.

ASSETS: Facilities classified as water conveyance assets include Kirkwood Penstock & valvehouse; Holm Penstock & valvehouse; Cherry Power Tunnel and Cherry Valley Pump Station; Priest Gate Tower; Priest Canal; Moccasin Power Tunnel & surge tower; West Portal valvehouse; Moccasin Penstock; Moccasin Low Head Powerhouse Penstock; Moccasin Low Head Powerhouse tailrace channel; surge tanks; sand traps; valves, valve houses, gates, and actuators; penstock monitoring systems, and related power systems.

Justification
Some of the water conveyance system is well beyond the original service life. Proactive evaluation of water conveyance assets and planned capital investments reduce the water delivery curtailments and interruptions in water delivery.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Loss or reduced capacity of any one of these facilities could impair the ability to deliver water from the Tuolumne River to SFPUC customers. Loss of these systems will also impact power generation from the HHWP Project.

SCOPE: Deliver capital improvement projects to sustain the reliability and safety of Priest Dam. Note: this project is ongoing, but does not currently forecast budgetary needs beyond what has already been allocated. Once the condition assessment is complete, a determination can be made regarding future funding requirements.

PROJECT DESCRIPTION: It is proposed to conduct a condition assessment and perform a stability analysis of the dam using current standards and analysis techniques. New instrumentation will be installed to monitor and document movement of the dam under different storage conditions. The results of these efforts will be used to determine whether a future capital improvement project is required.

ASSETS: Represented asset families include Priest Dam and reservoir; spillway and energy-dissipating components; spillway channels to 100 yards downstream; trash racks and debris removal systems; water outlet conduits, gates, valves, and control systems; dam foundations and abutments; drainage system galleries, pumps, and drain piping; power, lighting, mechanical, and HVAC systems; security and emergency communication systems; access roads and bridges; instrumentation and monitoring systems; and SCADA.

Justification
Priest Dam is an earth and rock-filled dam situated just east of Moccasin on Rattlesnake Creek in Tuolumne County. The dam was built between 1921 and 1923; it is approximately 168 feet tall and 1,000 feet wide, with a crest width of 20 feet. Priest Dam has a long history of issues related to settlement and deflection. Unresolved dam safety deficiencies (e.g., continued settlement) could influence California Division of Safety of Dams to issue dam operating restrictions limiting the operating water surface elevation range, reducing maximum water surface elevation, or increasing dam safety surveillance requirements. Water surface elevation restrictions would impair the regulating benefits of the reservoir.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
The dam not only serves as a regulating forebay for Moccasin Powerhouse but plays an important role in meeting SFPUC water deliveries from the Tuolumne River. In the event of an unplanned outage of facilities upstream of Priest Reservoir, storage in this reservoir can provide sustained SFPUC water deliveries for 2-5 days, providing an opportunity HHWP to address the outage or for the Water Supply and Treatment Division to increase deliveries from the local system.

Storage in Priest Reservoir is also used to sustain SFPUC water deliveries during short, planned maintenance events for assets upstream of Priest Reservoir. California Division of Safety of Dams accepted HHWP's Dam Safety Program requirement for periodic condition assessments. The dam was constructed in 1923 and future capital projects are anticipated.

Budget Change No Schedule Change Yes Scope Change No
Reason for Change

SCOPE: The March 2018 storm caused a large landslide above Priest Reservoir. This project stabilized the landslide area to prevent further erosion of the slope and sediment deposition into Priest Reservoir.

PROJECT DESCRIPTION: The project involved removal of unstable soil and rock, installation of permanent slope drainage, placement of permanent erosion control armoring and stabilizing structures, and installation of a new culvert with inlet and outlet protection.

ASSETS: Priest Reservoir
Justification
Continued soil and sediment deposition from the slide into Priest Reservoir directly affects water quality of the Tuolumne River water supply to SFPUC customers. Under current conditions, slide material has potential to cross the access road to Priest Gate Tower, the inlet to Moccasin Powerhouse.

Preserving access to the gate tower is essential for reliable operation of the dam and reservoir. This project has been funded by reallocating funds from existing CIP projects, and no funding is being requested in this plan. This project is in the closeout phase.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Stabilizing the slide prevents continued elevated turbidity concerns, preserves access to the gate tower, and reduces road maintenance.

Budget Change Yes Schedule Change Yes Scope Change No
Reason for Change
The change in budget is a result of reduced actual costs to complete the project. The schedule has been extended to match with the forecast project closeout.

SCOPE: Provide a reliable hydraulic bypass and energy dissipation system, conveying water around the turbines to Kirkwood Powerhouse Bypass Chamber and Mountain Tunnel.

PROJECT DESCRIPTION: Upgrade/replace high-pressure energy-dissipating valves, control systems, and associated structures to absorb 1,245 feet of pressure head and 430 cubic feet per second flow without damage.

ASSETS: Kirkwood Generator Bypass
Justification
The existing hydraulic bypass and energy-dissipation system cannot be operated for more than about two weeks without incurring significant damage. When operated, the impact from the high-pressure/high-flow water destroys the energy-dissipating structures in the bypass structure. The bypass chamber was repaired in 2017 and 2019 following short operational periods. Funding for this project is not scheduled until FY 27/28.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
When SFPUC power transmission lines are de-energized, water deliveries to SFPUC customers from the Tuolumne River must be diverted through the Kirkwood Generator Bypass. This project increases HHWP operating flexibility by decoupling water delivery from power production. This enables HHWP to meet scheduled water deliveries by utilizing the Kirkwood Generator Bypass system in the event Kirkwood Powerhouse, Early Intake Switchyard, Intake-Warnerville 230 KV Transmission Lines #5 or #6, or Warnerville-Standiford 115 KV Transmission Lines #7 and #8 are curtailed or de-energized. (Examples of curtailment or de-energization activities affecting these assets include wildfire, transmission outages, or construction.) Budget Change Yes Schedule Change No Scope Change No
Reason for Change
The change in budget is a result of increased construction cost due to escalation.

Project Manager: Russ Stipelcovich Current Active Phase: Pre-Construction Prior Approved Budget: $ 27,391,426 Proposed Budget: $ 41,055,930 Prior Approved Start: 09/18/2020 Proposed Start: 09/18/2020 Prior Approved Finish: 12/01/2027 Proposed Finish: 12/01/2027 Description
SCOPE: Provide a reliable hydraulic bypass and energy dissipation system, conveying water around the turbines to the Moccasin Powerhouse Tailrace.

PROJECT DESCRIPTION: Upgrade/replace high-pressure energy-dissipating valves, control systems, and associated structures to absorb 1,147 feet of pressure head and 430 cubic feet per second flow without damage.

ASSETS: Moccasin Generator Bypass
Justification
The existing hydraulic bypass and energy-dissipation system cannot be operated for more than about two weeks without incurring significant damage. When operated, the impact from the high-pressure/high-flow water destroys the energy-dissipating equipment in the bypass structure.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
When HHWP power transmission lines are de-energized, water deliveries to SFPUC customers that normally pass through the Moccasin Powerhouse generators must be diverted through the Moccasin generator bypasses. This project increases HHWP operating flexibility by decoupling water delivery from power production. This enables HHWP to meet scheduled water deliveries by using the Moccasin Powerhouse bypasses in the event Moccasin Powerhouse, Moccasin Switchyard, or Moccasin-Newark 115 kV Transmission Lines #3 and #4 are curtailed or de-energized, e.g., wildfire, transmission outage, construction.

SCOPE: Deliver capital improvement projects to sustain the reliability of HHWP's electric transmission assets from the generator step-up transformer across transmission lines to the terminal substations and switchyards. HHWP has developed a program to extend the life of these assets prior to wholesale replacement.

PROJECT DESCRIPTION: The program will include inspections, condition assessments, design, environmental evaluations, construction when appropriate to sustain the reliability of the electric transmission system, and development of a business plan for transmission rebuild.

ASSETS: Represented asset families include high voltage electric switchyards, substations, and transformer decks; buss structures; circuit breakers; transformers, pull boxes, & foundations; switches & disconnects; relays; capacitors; conductors, optical ground wire, fiberoptic cable, & grounding wires; transmission towers and footings; insulators, dead-ends, and connectors; instrumentation and control systems; and SCADA.

Justification
SFPUC maintains 162 miles of 115 kV and 230 kV electric transmission line miles from HHWP powerhouses to PG&E's Newark Substation in the Bay Area. Most of the towers were erected between 1925 and 1960. A 2009 condition assessment cataloged the structural condition of the towers, electrical conductors, insulators, switches, and relays. Some of the equipment is reaching the end of their planned useful life. HHWP performs reoccurring five-year inspections of structural lattice members and bolts. HHWP is requesting funds to review the condition assessment, develop a business plan for transmission rebuild, develop an Alternatives Analysis Report, and prioritize plan for work to 1) minimize impact to SFPUC water operations; and 2) minimize impact on HHWP water and power operations due to electrical grid transmission construction improvements being performed by other entities. This funding would also cover emergency repairs that cannot wait for systematic and prioritized repair.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Water Delivery Impact: SFPUC deliveries from the Tuolumne River are coupled to the hydroelectric generation at Kirkwood and Moccasin Powerhouses. The powerhouses reduce the line pressure of the Tuolumne River supply to levels compatible with pipeline pressure ratings across San Joaquin Valley. Failures in the electric transmission system cause the powerhouses to shut down, interrupting deliveries from the Tuolumne River to SFPUC customers.

Power Revenue Impact: The SPFUC must develop a long-term business strategy for their transmission assets to manage their costs and optimize revenues for their power generation.

Lines 7/8 Upgrades
Facility Category: Power Infrastructure
Project Manager: Edward Allen Current Active Phase: Construction Prior Approved Budget: $ 37,969,000 Proposed Budget: $ 37,327,197 Prior Approved Start: 12/02/2019 Proposed Start: 12/02/2019 Prior Approved Finish: 01/31/2025 Proposed Finish: 01/31/2025 Description
SCOPE: HHWP electric transmission Lines 7/8 convey power from Warnerville Substation to Modesto Irrigation District's Standiford Substation. This project will replace existing conductors along Transmission Lines 7 & 8 to mitigate the impacts of new renewable power generation being added to the California electrical grid.

PROJECT DESCRIPTION: This project develops the scope of work, design, and contract documents necessary to bid, award, and manage the reconductoring contract. Reconductoring will include replacement of the existing 115 kV conductors on Lines 7/8 from Warnerville to Standiford substations, resulting in increased capacity and resolving clearance detections.

The project is primarily funded by renewable generation developers interconnecting to the California electrical grid who have an adverse impact on Lines 7/8. Remaining funding came from capital funds previously allocated to the Transmission Line Clearance Mitigation Project (10014089).

ASSETS: Transmission Lines 7/8
Justification
New renewable generation projects are being connected to the California electrical grid, which is managed by the California Independent System Operator (CAISO). These new generation projects can have an adverse impact on existing transmission facilities, including assets owned and operated by HHWP. HHWP has performed an analysis and determined generation projects associated with CAISO Clusters 7 through 9 have an adverse impact on Lines 7/8. HHWP has developed a mitigation project to reconductor Lines 7/8, beginning at HHWP Warnerville Substation and terminating at Modesto Irrigation District's Standiford Substation. Without modifications, HHWP transmission will have reliability issues, requiring HHWP to reduce generation at Holm and Kirkwood Powerhouses. HHWP has developed a mitigating project that will be partially funded by the Cluster 7 through 9 developers.

Reconductoring with tower modifications also resolves multiple locations where the clearance between the existing conductors and the ground or structures do not meet current safe clearance regulations.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
New renewable generation projects connecting to the California electrical grid will impact the reliability of HHWP Lines 7/8 from Warnerville to Standiford. If the project is not completed, HHWP will be required to reduce generation at Holm and Kirkwood powerhouses to mitigate the impact of the new renewable generation projects after they connect to the California electrical grid.

SCOPE: The powerhouse was completed in 1969 and generates a combined maximum output of 110 megawatts. Both generator units and transformers have exceeded their life expectancy and need repair to continue operating reliably. Since their original installation, the generators have not had major maintenance work performed (no rewinds or overhauls).

PROJECT DESCRIPTION: The project is broken down into three components: 1) Generator Rehabilitation – replace the entire generator and associated equipment, including new stator cores and coils, rotor poles, relays, and rotor rim; 2) GSU Replacement – replace two of the three existing generator step-up transformers (GSUs), new foundations and oil containment, and relay upgrades; and 3) Power Plant Systems Upgrades – replace the 480 V switchgear, 13.8 kV switchgear, motor control centers, main control boards, protective relays, cooling water piping, and improving oil containment systems.

ASSETS: Moccasin Powerhouse
Justification
The Moccasin Powerhouse is a vital component of the Hetch Hetchy Regional Water System. When Moccasin Powerhouse or generator step up transformers are out of service, water deliveries to SFPUC customers from the Tuolumne River can be impacted. The units have become less reliable and have resulted in 35 outages over a four-year period (2018-2021).

Procurement of failed components may require a procurement period of 18 months or more for long-lead items (e.g., transformer replacement or generator rewind components). Loss of both hydro-generation units, or GSUs, will result in a loss of water deliveries from the Tuolumne River to SFPUC customers for an extended period of time.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Potential loss of reliable water delivery from the Tuolumne River to SFPUC customers and potential loss of power generation.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The forecasted project cost exceeds the budget for the following reasons: 1) HH-1003R had a construction cost overrun of approximately $4 million due to unforeseen site conditions and additional construction management costs; 2) DB-121R2 final completion will be delayed one year due to supply chain issues; subsequently, DB-121R2 construction management costs are expected to increase by approximately $2 million; and 3) the MPH Systems Upgrade Conceptual Engineering Report construction cost estimate increased to $25 million from the Needs Assessment Report estimate due to additional scope, scope refinement, higher construction and procurement costs, and a one- year construction delay to allow more time for coordination. Construction management costs are expected to increase by approximately $3 million.

SCOPE: Mitigate noncompliant clearance distances between high-voltage conductors and ground/structures. In 2012, HHWP identified safety clearance discrepancies, e.g., ground, wire, building, and streetlights that endanger the public and property.

PROJECT DESCRIPTION: This project will provide funding to implement mitigation measures to resolve clearance discrepancies.

Mitigation options include but are not limited to new towers/tubular poles, new intervening poles, tower raises, ground lowering, and other structural improvements to the lattice towers.

ASSETS: Represented asset families include high voltage electric transmission towers and footings; insulators, switches, disconnects, & dead-ends, and connectors; conductors, optical ground wire, fiberoptic cable, & grounding wires; instrumentation and control systems; SCADA; relays and switches; right-of-way corridors and access roads; and instrumentation and controls.

ADDITIONAL COMMENTS: Title and project manager have been updated to reflect the change in project management team - from HHWP R&R to HHWP Strategic Capital Planning & Special Projects - through the end of the project.

Justification
Non-compliant clearances present a safety hazard to the public and SFPUC employees, increase SFPUC's wildland fire risk, and contribute to transmission line outages.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Public safety issue.

SCOPE: Replace the bypass valve diffuser and renew the bypass draft tube and chamber.

PROJECT DESCRIPTION: Design, fabricate, and install a reliable hydraulic bypass and energy dissipation system, conveying water around the turbines to Kirkwood Powerhouse Bypass Chamber and Mountain Tunnel.

ASSETS: Kirkwood Powerhouse bypass valve and actuator; controls; bypass draft tube and lining; energy dissipators; bulkhead gate and rails; bypass draft tube/tunnel transition; and SCADA.

Justification
Deliveries for SFPUC water customers from the Tuolumne River, not requiring filtration at Sunol Valley, must pass through Kirkwood Powerhouse (generator or generator bypass). During emergencies when the hydroelectric generators or transmission are off-line, the SFPUC water deliveries are diverted through this generator bypass valve that reduces the water pressure. Without this project, SFPUC water deliveries are interrupted during Kirkwood Powerhouse outages (e.g., wildfire, construction, or maintenance).

This project was approved in an earlier CIP, and no funding is being requested in this plan. This project is in the closeout phase Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Deliveries meeting filtration avoidance for SFPUC water customers from the Tuolumne River can be interrupted during Kirkwood Powerhouse/transmission line outages, e.g., wildfire, construction, or maintenance.

SCOPE: Deliver capital improvement projects to sustain the reliability of four hydroelectric powerhouses from turbine isolation valves to generator step-up transformer and 100 yards downstream of tailrace gates.

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of powerhouse assets prior to wholesale replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate, to sustain the reliability of hydroelectric powerhouses with capital improvements. This project includes investments in the following systems:
1) turbine and governors; 2) generator and excitation; 3) electrical - powertrain, and station service and protection systems; 4) step-up transformers; 5) mechanical systems; 6) civil/structural systems; and 7) tailrace channel.

ASSETS: Holm Powerhouse, Kirkwood Powerhouse, Moccasin Powerhouse, Moccasin Low Head Powerhouse, generator step-up transformers, turbine shutoff valves; turbine bypass valves; draft tubes; structures; and tailrace gates; and SCADA.

Justification
Proactive evaluation of hydroelectric generation assets and planned capital investments reduces the forced outage rate and interruptions in water deliveries from the Tuolumne River to SFPUC customers (Kirkwood and Moccasin powerhouses only).

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Unplanned and forced outages at HHWP powerhouses can impact our ability to generate power and deliver water from the Tuolumne River to SFPUC customers. This project provides funding to proactively evaluate our hydroelectric generation assets, and address forced or unplanned equipment failures.

SCOPE: When the Cherry-Eleanor pump system was constructed, it enabled diversion of approximately 110,000 acre-feet of water annually from Lake Eleanor to Cherry Reservoir, resulting in an additional 220 GWh annually (about 13 percent of the annual generation from the project). Pumps in Cherry Reservoir have exceeded their life expectancy. Five out of ten pumps are inoperable and the remaining five pumps are at continued risk of failure. All ten pumps have failed in the past and have been repaired or replaced at various times since being installed.

PROJECT DESCRIPTION: Replace and upgrade pumps in Cherry Pump Station with units that work with current operating strategies. The scope of work includes: 1) replacement of pumps, transformer, and pump motor starters; 2) installation of Programmable Logic Controller (PLC), SCADA system, and fiber optics; and 3) improvement of the existing motor control center (MCC) building.

ASSETS: Cherry Eleanor Pumps
Justification
Cherry Reservoir Pump Station facilitates conveyance of water from Lake Eleanor to Cherry Reservoir via Cherry Diversion Tunnel. Water from Cherry Reservoir enables cost-effective generation of hydropower at Holm Powerhouse. When all pumps are operational, the additional water from Lake Eleanor allows for increased power generation.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.

Operating Impact
Not all pumps are functioning at this time. This project will recover lost Holm Powerhouse generation.

SCOPE: Access to Holm Powerhouse is off of Cherry Oil Road via Holm Bridge. This road is open to the public. The 136-foot bridge is a three-span, continuously supported bridge that carries two lanes of two-way traffic over Cherry Creek. The bridge was built in 1957 and requires replacement to address seismic and current Caltrans design standard deficiencies (e.g., T beam steams, end diaphragms, and lateral struts).

PROJECT DESCRIPTION: Replace the 136 foot, three-span, continuously supported bridge over Cherry Creek.

ASSETS: Holm Bridge
Justification
The bridge provides the only access to Holm Powerhouse and recreational access to Cherry Creek.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Operating Impact
Holm Powerhouse can only be accessed via Holm Bridge. Without the bridge, maintenance of the powerhouse and the associated facilities in the area will be very difficult.

SCOPE: HHWP owns assets in areas designated by California Public Utilities Commission as "High Fire Threat Zones." HHWP has evaluated prevention, mitigation, and response strategies to mitigate the threat of wildfire.

PROJECT DESCRIPTION:

This project will fund wildfire mitigation vegetation management projects, including fuel breaks and Integrated Vegetation Management (IVM) projects to protect assets classified as "Power" only. This project does not fund annual vegetation management plans.

Transmission line IVM: (Power)
This project will remove fire prone brush species and any hazard fall-in risk potential trees (including outside the Right of Way) along HHWP Transmission Lines. The Right of Way vegetation will be replanted with low growing native grass and pollinator species. Where applicable, in areas with increased conductor height, the project will re-plant conifer and hardwood trees. Annual maintenance after replanting would include target herbicide applications, brush removal and monitoring of replanted vegetation.

Water Quality IVM: (Power)
Wildfire can impact the water quality of water that could enter Priest Reservoir. The Wildfire Mitigation will include mastication, chain- sawing, and hand-clearing to remove undesirable woody species; dead, diseased, or otherwise hazardous trees; and foliar herbicides including but not limited to Yellow Star Thistle and Himalayan Blackberry. Vegetation along roadways and parking areas will be thinned and scaffold branches lifted to insure adequate access during fire events. The project will include introduction of native vegetation including milkweed, black oak, and ponderosa pines in appropriate areas to promote diversity, pollinator habitat and fire resilience.

Projects will also include creation of other permanent fire breaks to protect power funded assets.

ASSETS: Transmission Lines 1&2, 5&6 and 9,10 &11, Intake Switchyard, Priest Reservoir Justification
Hetch Hetchy Water and Power's wildfire mitigation projects will vary by asset, location, and terrain. Wildfire is continuing to become more prevalent in California, requiring additional resources to mitigate risks and maintain operations.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.

Operating Impact
Wildfire threatens the Hetch Hetchy project area and neighboring lands. Uncontrolled wildfire presents a safety risk to staff and the public and could potentially limit HHWP's ability to deliver water and, generate power. This project has a positive impact on operations by improving the system's resiliency to wildfire in a sustainable manner as well as reducing the likelihood of ignition.

SCOPE: Deliver capital improvement projects to sustain the reliability of Priest Dam.

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of this asset prior to replacement. The program includes inspections, condition assessments, design, environmental evaluations, and construction when appropriate.

ASSETS: Represented asset families include Priest Dam and reservoir; spillways and energy-dissipating components; spillway channels to 100 yards downstream; trash racks and debris removal systems; water outlet conduits, gates, valves, and control systems; dam foundations and abutments; drainage system galleries, pumps, and drain piping; power, lighting, mechanical, and HVAC systems; security and emergency communication systems; access roads and bridges; instrumentation and monitoring systems; and SCADA.

Justification
The dam not only serves as a regulating forebay for Moccasin Powerhouse but plays an important role in meeting SFPUC water deliveries.

In the event of an unplanned outage of facilities upstream of this facility, storage in Priest Reservoir can provide sustained SFPUC water deliveries for 2-5 days, providing an opportunity HHWP to address the outage or for WST to increase deliveries from the local system.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Unresolved dam safety deficiencies could influence California Division of Safety of Dams to issue dam operating restrictions, limiting the operating water surface elevation range, reducing the maximum water surface elevation, or increasing dam safety surveillance requirements. Water surface elevation restrictions would impair water and power benefits of the reservoir.

SCOPE: Early Intake Dam is a single-curvature concrete arch structure. It was constructed between 1923 and 1924 to direct deliveries from the Tuolumne River into Mountain Tunnel for San Francisco water customers. Within a few years of the dam's completion, significant cracking was observed at several locations, most likely due to the absence of contraction joints in the structure. In addition, widely distributed and progressively worsening distributed cracking has been observed throughout the dam and spillway structure over the years.

A 1966 study concluded that the cause was alkali aggregate reaction and the resultant internal expansion of the concrete (Clair A. Hill 1966). Following that study, SFPUC carried out several repair measures to attempt to reduce the rate of deterioration of the dam's concrete. A follow-up study in the late 1980s and early 1990s was undertaken to reevaluate the condition of the dam. Due to the state of deterioration and difficulty of making lasting repairs, the study recommended replacement of the dam rather than repair (Woodward- Clyde Consultants 1992). In 2007, a preliminary stability analysis performed by URS also recommended dam removal and replacement rather than repair (URS 2007). The dam is reaching the end of its design life. Engineering studies concluded that permanent repair of the alkali aggregate reaction concrete is not feasible, and the dam should be replaced.

PROJECT DESCRIPTION: Early Intake Dam Interim Improvement Project will provide the needed engineering alternative studies to determine the scope and cost for the long-term remediation and planning to address the deterioration and structural concerns of the existing concrete dam.

ASSETS: Early Intake Dam
Justification
SFPUC is responsible for developing and maintaining a mature dam safety management program. This project is intended to meet this objective, to maintain dam safety, and to meet the dam safety requirements of California Division of Safety of Dams.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Budget Change Yes Schedule Change No Scope Change Yes
Reason for Change
The original scope included provisions for an interim repair and improvement to extend the life of the dam until the dam is replaced.

Updated engineering studies concluded that interim improvements are not effective. The change in scope and budget is a result of moving the scope of completing the conceptual engineering study to the Early Intake Dam Long-term Project to define the scope for replacement of the dam.

SCOPE: Early Intake Dam is in an advanced stage of deterioration, with severe cracking of the concrete structure as a result of internal expansion from concrete alkali aggregate reaction. Past engineering studies concluded that permanent repair of the alkali aggregate reaction concrete is not feasible, and the dam should be replaced. Recent studies in 2020 and 2021 revealed additional structural stability concerns and concluded that interim remediation measures are not feasible.

PROJECT DESCRIPTION: 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.

ASSETS: Early Intake Dam
Justification
This project is needed to ensure dam safety and long-term reliable water delivery. Without Early Intake Dam, HHWP would not have a way to divert water from Lower Cherry Aqueduct and Tuolumne River upstream of Kirkwood Powerhouse into Mountain Tunnel during drought or emergency conditions.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Operating Impact
Under normal operations, the SFPUC Tuolumne River water supply flows from O'Shaughnessy via O'Shaughnessy Diversion Works to Canyon Tunnel, then through Kirkwood Penstock and Kirkwood Powerhouse, then through Intake Bypass Tunnel to Mountain Tunnel. In the event of drought or failure of O'Shaughnessy Diversion Works, Canyon Tunnel, Kirkwood Penstock, or Intake Bypass, Early Intake Dam is required to direct water from the Tuolumne River, or from Lower Cherry Aqueduct, into Mountain Tunnel. This project provides a critical alternative mean to divert water from the Tuolumne Watershed into Mountain Tunnel for deliveries to SFPUC customers under drought and/or emergency conditions when Kirkwood Powerhouse and bypass are not operable.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The original estimate was based on an order of magnitude estimate. Updated engineering study of conceptual alternatives with more detailed evaluation found that more extensive scope and environmental permitting efforts are needed to remove and replace the dam. The increase in schedule and budget reflects higher construction and development costs due to challenges in site constraints, seasonal and operational restrictions, management of river flows during construction, environmental approvals, compliance environmental requirements, and additional escalation.

SCOPE: HHWP has developed a program to extend the life of approximately 80 buildings, structures, facilities, and systems prior to replacement. Facilities provide office space; warehousing of materials, supplies, and critical spare equipment; maintenance and vehicle shops; fire suppression systems; HVAC; water treatment, storage, and distribution facilities; wastewater collection, treatment, and discharge facilities; stormwater collection and discharge facilities; and cottages for essential onsite workers and NPS/USFS staff. This program delivers capital improvement projects to sustain serviceability and extend the asset life of facilities used to meet Hetch Hetchy Regional Water System objectives.

PROJECT DESCRIPTION: The program includes inspections, condition assessments, design, environmental evaluations, and construction, when appropriate. Typical projects include roof and waterproofing replacements; security, fire detections/suppression, and HVAC upgrades; building remodels to meet current business/operational needs; replacement of rotted/deteriorated structures; replacement of deteriorated underground pipelines and conduits; and upgrades to water and wastewater treatment plants to meet current regulatory standards.

ASSETS: Represented asset families include the types of facilities described above at Cherry Compound, O'Shaughnessy Compound, Early Intake Compound, South Fork Yard, Moccasin Compound, Moccasin Fish Hatchery, Oakdale Service Yard, Rock River Lime Plant, and Warnerville Service Yard.

Justification
Many of these facilities and infrastructure were constructed in the early 1900s to facilitate the construction of the Hetch Hetchy Regional Water System. Capital improvements are needed to provide employees and staff with safe, comfortable, and efficient facilities from which to work.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Operating Impact
Disrepair of HHWP workplaces, system buildings, and facilities has led to reduced asset utilization and efficiency. Disrepair of asset components has led to unsafe work conditions which are responded to immediately upon notification. Deteriorated or absent facilities do not attract skilled workers who are necessary to meet succession planning and sustainability objectives.

SCOPE: Deliver capital improvement projects to sustain the reliability and safety of four upcountry dams: O'Shaughnessy Dam, Cherry Valley Dam, Lake Eleanor Dam, and Early Intake Dam.

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of dam assets prior to replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate.

ASSETS: Represented asset families include O'Shaughnessy Dam (circa 1923) and Hetch Hetchy Reservoir; Cherry Valley Dam (circa 1956) and reservoir; Lake Eleanor Dam (circa 1918) and reservoir; Early Intake Dam (circa 1925); spillways, spillway gates, and controls; energy-dissipating components; spillway channels to 100 yards downstream; trash racks and debris removal systems; water outlet conduits, gates, valves, face valves, and control systems; dam foundations and abutments; drainage system galleries, pumps, and drain piping; primary/backup power, UPS' and batteries; lighting, mechanical, and HVAC systems; security and emergency communication systems; access roads and bridges; instrumentation and monitoring systems; and SCADA.

Justification
HHWP's four upcountry dams were built between 1918 and 1956 and are exhibiting expected wear and tear. California Division of Safety of Dams accepted HHWP's Dam Safety Program requirement for periodic condition assessments. Given the age of the dams, it is anticipated that major repairs, security enhancements, and emergency communication system upgrades will be necessary.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Unresolved dam safety deficiencies could influence California Division of Safety of Dams to issue dam operating restrictions, limiting the operating water surface elevation range, reducing the maximum water surface elevation, or increasing dam safety surveillance requirements. Water surface elevation restrictions could impact the SFPUC water supply, increasing the frequency and level of water restrictions on SFPUC water customers.

SCOPE: Deliver capital improvement projects to sustain the reliability of access roads and bridges that provide vehicular access to HHWP dams, reservoirs, water conveyance facilities, hydroelectric powerhouses, switchyards and substations, and communication sites.

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate. Typical capital projects include resurfacing, retaining wall construction, drainage improvements, slope stability improvement, guardrail installations and replacements, rockfall hazard mitigation, and bridge rehabilitation.

ASSETS: Represented asset families include improved and unimproved roadways; chip seal and asphaltic-cement pavements; guardrails; retaining walls and road embankments; drainage systems; rock retention/deflection systems; and bridges, piers, abutments, and foundations.

Justification
Necessary compliance and safety improvements must be performed on paved roads and small bridges that are used by HHWP staff and the general public.

HHWP is responsible for maintaining access roads to all upcountry facilities, electric transmission towers, and San Joaquin Pipelines.

There are approximately 14 bridges, 40 miles of paved roadways, and hundreds of miles of unpaved roadways in the program. Paved roads are also used by the public. Periodic bridge inspections are necessary to prevent structural and foundation failures.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Operating Impact
Failure of roads and bridges can impact access to HHWP facilities. Failure of roads and bridges can also impact public access to public and private lands adjacent to the Hetch Hetchy Right of Way.

SCOPE: Deliver capital renewal and replacement projects to implement and sustain physical security at critical assets. Fund physical security upgrades at existing HHWP facilities. The security at many HHWP Moccasin and remote facilities lack sufficient security measures to minimize the risk of intrusion.

PROJECT DESCRIPTION: This project will fund security system measures that meet capitalization thresholds, including access monitoring and controls, fencing, card access, and camera monitoring.

ASSETS: Represented asset families include all HHWP "Joint" facilities, e.g., chemical dosing facilities; water quality sampling facilities; water treatment plants; wastewater treatment plants; corporation yards; communication equipment buildings; network operating centers; remote and auxiliary control rooms; data centers; fences and gates.

Justification
Water and power are critical services. Physical security is required to limit access to these facilities. In addition, physical security at some HHWP locations is regulated under state and Federal law. Changes in current regulations may require upgrades to existing physical security systems.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

SCOPE: Deliver capital renewal and replacement projects to implement and sustain regional communication assets. Voice and data communications flow over multiple communication systems, including microwave, two-way radio voice, voice over internet protocol (VoIP), plain old telephone system (POTS), 900 MHz radio, fiber-optic communication, and information technology networks (corporate business network, SCADA network, and third-party networks).

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of these assets prior to wholesale replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate. This project will enable HHWP to extend communications across dead zones to remote locations; replace obsolete technology in a strategic and planned approach; integrate voice and data services across the SFPUC; and modernize elements of the communication infrastructure to ensure serviceability, reliability, and, where pertinent, regulatory compliance.

ASSETS: Represented asset families include Warnerville Radio Shelter, Warnerville Substation, Albers Road Valve House, Mt. Allison, Roselle Crossover, San Joaquin Valve House, Tesla Portal, Oakdale Portal, Rock River, Red Mountain Bar West, Moccasin Peak Communication Site, West Portal, Priest Reservoir, Moccasin Radio Shelter, Moccasin Powerhouse, Moccasin Compound Server Building Datacenter, Duckwall Communications Site, Intake Radio Site, Jones Point, Intake Switchyard, Southfork Yard, Kirkwood Powerhouse, Holm Powerhouse, Cherry Compound, Cherry Pump Station, Eleanor Dam, Burn Out Ridge Communications Site, O'Shaughnessy Dam, Poopenaut Pass Communications Site, power systems, batteries, standby generators, power supplies, servers, network cards; antennas, wave guides, encoders/decoders, and SCADA.

Justification
HHWP Communication Systems enable essential command and control over the Hetch Hetchy Regional Water System, hydroelectric generation, and high-voltage transmission system. The communication system further integrates HHWP Water Operations with Water Supply and Treatment Division (for water) and neighboring Transmission Operators (power). A modern, redundant, and secure communication system support water and power system objectives. There are remote locations without reliable communications, where networked visibility would improve efficiencies in operations and personnel safety.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Operating Impact
HHWP dispatch and remote-control center is located in Moccasin and is manned by the Power System Operators. From this location, system operators monitor reservoir water surface levels, dam safety instrumentation, water flow, hydroelectric generator production, electric transmission and distribution lines, and fire and life-safety systems. Operators dispatch personnel responding to routine and emergency conditions, and notify management of unplanned situations (e.g., wildland fires, floods, traffic accidents, and other emergencies). Reliable communications are essential for the safety of staff, and to operate the system from Yosemite National Park to Sunol Valley near San Francisco Bay Area.

SCOPE: Canyon Tunnel was built in the 1960s. A condition assessment was performed on the tunnel in 2009; the tunnel is generally in good condition, with the exception of Hetchy Adit, a tunnel access point. Temporary repairs have been made to the plug at this adit in 1986, 1989, and 2009, but permanent repairs are needed to reduce leakage and increase the reliability of the system. During construction of Canyon Power Tunnel, the O'Shaughnessy Adit Access Bridge was built in 1960 to provide sole access over the Tuolumne River to Hetchy Adit. The bridge is approximately 84 feet long and is a four-span simply supported bridge with a timber deck and concrete piers. It is located 0.5-miles downstream of O'Shaughnessy Dam and provides one lane two-way access along the access road. Since the O' Shaughnessy Adit Access bridge, as the sole access point to Canyon Tunnel – Hetchy Adit, impacts the proposed work inside Hetchy Adit, there should be a time saving and improved efficiency by combining the two projects.

PROJECT DESCRIPTION: The project is to install a new reinforced concrete plug downstream of the existing plug in Hetchy Adit and rehabilitate O'Shaughnessy Adit Access Bridge including sub-structure retrofit and super structure replacement.

ASSETS: Canyon Tunnel and O'Shaughnessy Adit Access Bridge Justification
The existing concrete plug in Hetchy Adit has been experiencing a leakage problem. Multiple attempts to fix the leakage have failed. If the plug is not replaced, water will continue to leak out and eventually lead to the collapse of the concrete plug structure. If the adit collapses, Canyon Tunnel will not be able to convey water which will affect both water deliveries to SFPUC customers and power generation. Also, the new plug will be equipped with a large access door to allow maintenance vehicle to enter the tunnel in case of emergency. This will help shorten the time of return of service. O'Shaughnessy Adit Access bridge is not seismic resistant. The concrete foundation and piers have experiencing scaling of concrete due to stream flow exposing aggregate. Some parts of the wooden deck have rotted and need to be replaced. If the bridge collapses, it will cut off the only the vehicular access to Hetchy Adit which leads to Canyon Tunnel.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Operating Impact, Environmental Stewardship, and Sustainability.

Operating Impact
Failure at Hetchy Adit will impact water deliveries from the Tuolumne River to SFPUC water customers, reducing maximum deliveries from 310 mgd to about 80 mgd (maximum filtration capacity at Sunol Valley Water Treatment Plant for water from the Tuolumne River watershed). Failure of the O'Shaughnessy Adit Access bridge restricts access to Hetchy Adit and Canyon Tunnel Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The change in budget, schedule, and scope is a result of moving the O'Shaughnessy Adit Bridge scope from the Bridge Replacement Project to this project.

SCOPE: Moccasin Wastewater Treatment Plant (WWTP) provides primary treatment of wastewater from Moccasin Compound prior to discharging treated water to a nearby spray field. The WWTP was constructed in the 1970s and has been in continuous operation since its installation. The WWTP has reached the end of its reliable service life and is becoming increasingly maintenance-intensive. Additionally, Moccasin has no backup treatment so failure of the plant would have significant consequences.

PROJECT DESCRIPTION: This project will replace the existing plant with a package two-train sequencing batch reactor (SBR) plant with grit removal and screening facilities, upgraded electrical and flow monitoring systems, flow equalization, SCADA instrumentation and automation features, and related site improvements.

ASSETS: Moccasin Wastewater Treatment Plant
Justification
The useful life for mechanical and electrical equipment in treatment facilities is typically 15 to 25 years, according to EPA and ASCE publications. Given the age and condition of the WWTP as well as its process and operational limitations, investing in improvements to address individual WWTP systems and component deficiencies is not practical in comparison to installation of a new replacement plant. At more than 40 years old, the Moccasin WWTP is at the end of its useful service life and is becoming increasingly maintenance-intensive.

Some of the treatment plant's operational limitations and challenges include: 1) poor upstream screening facilities, resulting in limitations for bar screens to retain smaller materials, which has also caused operational issues and mechanical equipment failure in the bioreactor; 2) inadequate sizing of the partial flume, resulting in adverse effects from solids, rocks, grit, rags, and debris during low flows; 3) lack of a grit removal facility; 4) lack of aeration control in the plant's aeration basin; 5) lack of an automated monitoring/control system; 6) continual mechanical failures of the settling tank; 7) difficulty in controlling sludge return rates; 8) poor flow distribution from the aeration tank to the clarifier; 9) pump station overruns at the plant when flows are high, resulting from the lift station's minimum pump capacity exceeding the maximum effluent channel pumps at the treatment plant; and 10) major corrosion to electrical panels.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability Operating Impact
The existing WWTP is the only wastewater plant serving the Moccasin Compound. Failure could result in discharge of untreated wastewater into Moccasin Creek, which flows into Don Pedro Reservoir.

SCOPE: Mountain Tunnel (MT) was constructed between 1917 and 1925 and is a critical, nonredundant link in the Regional Water System, conveying SFPUC Tuolumne River 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 2017 MT Inspection and Repairs Project provided an update to 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 MT Improvements (Rehabilitation) Project was selected for design and construction of the preferred engineering alternative that will keep this vital component of the Regional Water System in reliable service for years to come. The budget and schedule are based on the MT Improvement Project construction phase, which is anticipated to take place between 2021 and 2027. Note: This is the Joint portion of the MT project.

PROJECT DESCRIPTION: The Joint portion of the Mountain Tunnel Improvements consists of work related to the construction of the Flow Control Facility and Priest Adit Tunnel.

ASSETS: Mountain Tunnel
Justification
Continued tunnel lining degradation could lead to catastrophic failure. The likely type of anticipated failures are "local collapses," which would not impact power generation but would create water quality events in terms of turbidity in the water supply. The likelihood of localized collapses is moderate to high. Depending on the configuration of the system, this type of event could interrupt deliveries of the Tuolumne River supply to SFPUC water customers.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Depending on the configuration of the system, a "local collapse" could interrupt delivery of Tuolumne River water to the SFPUC customers.

Continual degradation of the asset could lead to a catastrophic failure.

SCOPE: 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 Valley 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.

PROJECT DESCRIPTION: This project will re-establish 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.

ASSETS: Cherry Dam Spillway
Justification
The complete length of channel that passes water from the ogee side spillway to Cherry Creek is entirely unlined, which will result in continued erosion if subjected to even minimal spillway discharge. Erosion from a spillway release and a landslide in 2010 along the upper spill channel caused overtopping of the left bank and created a 1,500-feet long eroded channel to the Cherry Creek.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.

Operating Impact
Failure to adequately address this issue could result in an operation restriction from California Division of Safety of Dams, reducing maximum storage limits, and increasing frequency and level of rationing for SFPUC water customers.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The change in scope, budget, and schedule is a result of findings from an updated engineering study that re-establishing the damaged spill channel section and armoring the upper spill channel for protection against erosion from spillway discharges of up to 2,000 cubic feet per second are adequate criteria for a short-term interim improvement.

SCOPE: Eleanor Dam is a multiple-arch reinforced concrete dam that was constructed in the 1920s. The 2015-2016 Needs Assessment Report identified concerns related to deterioration and aging of the structure, inadequate spillway capacity, and dam safety. Specifically, structural/seismic concerns were identified regarding Eleanor Bridge, cracking and spalling of concrete, exposed rebar, significant leakage through the arch barrels, cracks and erosion of the spillway concrete, and insufficient spillway capacity to pass the design flood. The project scope will include the rehabilitation of the dam to address the identified deficiencies and replacement of the bridge across the top of the dam. The scope also includes an interim repair of the bridge to extend the service life until the bridge is replaced.

PROJECT DESCRIPTION: 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.

ASSETS: Eleanor Dam
Justification
The SFPUC is responsible for developing and maintaining a mature dam safety management program. This project is intended to meet this objective.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.

Operating Impact
Loss of operational functionality of this dam will result in reduction of carryover storage levels for SFPUC water customers. Loss of water storage will impact the frequency and level of rationing for our SFPUC water customers. In addition, generation produced by water stored behind this dam contributes to about 15 percent of HHWP's annual generation.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The change in scope, budget, and schedule is a result of expanding the scope to include replacement of the Eleanor Dam Bridge; a more detailed evaluation of the project plan to reflect a more difficult construction with more challenging site, seasonal and operational, and environmental limitations, environmental approvals and permitting; and additional escalation from a more extended schedule.

SCOPE: Deliver capital improvement projects to sustain the reliability of HHWP's electric distribution lines. HHWP owns and maintains about 40 miles of distribution lines which power operational facilities on the HHWP Project. About 60 percent of the distribution system has exceeded its life expectancy, resulting in multiple failures at Moccasin Compound. In addition, new loads to support operations at Moccasin Compound and remote sites (e.g., UV systems, Moccasin Fish Hatchery Recirculation System, and new buildings/offices) are taxing the current system, requiring mitigation. This project funds load studies and condition assessments to evaluate current and future needs; replacement of failing systems; design to meet current/future needs; and procurement of critical spare equipment to ensure reliable 24/7 water and power operations at Moccasin Compound and remote sites.

PROJECT DESCRIPTION: The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate, to sustain the reliability of the electric distribution system.

ASSETS: Represented asset families include circuit breakers; transformers; relays; capacitors; conductors; poles, cross-arms, tie-backs, anchors, and dead-ends; insulators and connectors; instrumentation and control systems; SCADA; and other power-distribution supporting infrastructure.

Justification
Interruptions in power delivery to HHWP facilities interrupts water and power systems' supervisory and control processes, impedes worker productivity, and interrupts computing processes. Capital improvements are needed to ensure reliable distribution power for current and future needs, to resolve nonstandard electric distribution conditions, and to increase operational flexibility.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability Operating Impact
Interruptions in power delivery to facilities interrupts water and power systems' supervisory and control processes and impedes worker productivity.

SCOPE: HHWP is responsible for maintaining 14 bridges within the HHWP Project. Condition assessments have identified needs for rehabilitation and/or replacement due to age and to meet current seismic design criteria. Two of fourteen bridges, Lake Eleanor Dam Bridge and O'Shaughnessy Adit Access Bridge, require substantial modification or replacement and have been combined into this project.

Lake Eleanor Dam Bridge, constructed in 1918, is a structural component of Lake Eleanor Dam, which is integral to the structural/seismic integrity of the arch dam. O'Shaughnessy Adit Access Bridge was built in 1960. It is approximately 84 feet long and is a four-span simply supported bridge with a timber deck and concrete piers. It is downstream of O'Shaughnessy Dam and provides one lane two-way access to Canyon Tunnel. Due to limited funding, the current project is funded to include two bridges only: O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge.

PROJECT DESCRIPTION: This project originally included rehabilitation and/or replacement of O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge. O'Shaughnessy Adit Access Bridge is the only access to Canyon Tunnel Hetchy Adit. The proposed work relating to the bridge and adit will be implemented under a single construction contract. Thus, SFPUC decided to combine the rehabilitation of O'Shaughnessy Adit Access Bridge with the Canyon Tunnel Hetchy Adit (Project #10014108). At the same time, Eleanor Dam Bridge is an integral part of the Eleanor Dam. Thus, Eleanor Dam Bridge replacement will be included as part of the scope of Eleanor Dam Rehabilitation (Project #10030759). The current proposed budget for the Bridge Replacement project will cover the planning efforts performed on these two bridge sub-projects so far. The planning efforts of O'Shaughnessy Adit Access Bridge and Eleanor Dam Bridge will continue under Canyon Tunnel Hetchy Adit (Project #10014108) and Eleanor Dam Rehabilitation (Project #10030759), respectively.

ASSETS: O'Shaughnessy Adit Access Bridge and Lake Eleanor Dam Bridge.

Justification
Compliance-driven and safety improvements must be performed for these bridges used by HHWP staff and the general public.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Operating Impact
Failure of these bridges restricts access to certain HHWP facilities.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The change in budget, schedule, and scope is a result of moving the bridge replacement design and construction scopes to the respective Canyon Tunnel - Hetchy Adit Rehabilitation and Eleanor Dam Rehabilitation projects.

SCOPE: 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 used currently for large equipment and critical spares for the Hetch Hetchy Water and Power system. Additionally, the building has documents and items of historical significance, which will require hazmat remediation, and a plan for disposition.

PROJECT DESCRIPTION: Design and install mitigation measures to prevent the building from collapsing and to prevent hazardous materials (such as lead-based paint and asbestos) from contaminating Moccasin Reservoir.

ASSETS: Moccasin Old Powerhouse
Justification
This project is intended to ensure safety of employees and water quality objectives.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability.

Operating Impact
If no suitable hazard mitigation actions are taken, the existing building will continue to deteriorate and increase the risks of collapse.

SCOPE: Moccasin Penstock was built in the early 1920s and conveys water, nearly one mile from Moccasin Power Tunnel to Moccasin Powerhouse. Moccasin penstock serves as the sole link in conveying water from Priest Reservoir to Moccasin Reservoir, from which water is routed to the San Francisco Public Utilities Commission (SFPUC) customers. A 2011 Condition Assessment Report identified numerous deficiencies. The penstocks contain segments of hammer-forged welded steel (HFWS) that has experienced failures in the past. This type of HFWS pipe has a history of brittle fracture failure at both Pacific Gas & Electric Company and Southern California Edison penstocks. In October 2022, Phased Array Ultrasonic Testing (PAUT) was used to evaluate hammer forged weld seams and visible cracks were discovered. In addition, issues have been identified regarding the anchor/saddle system with respect to alkali reactive silica, which degrades the concrete.

PROJECT DESCRIPTION: 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 ASSETS: Moccasin Penstock
Justification
The goal is to provide a reliable redundant conveyance with a 100-year life span.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability, Operating Impacts, Environmental Stewardship, and Sustainability.

Operating Impact
The Moccasin penstock system is a critical asset in the Hetch Hetchy conveyance system and there is no existing bypass around the penstocks. The initial risk assessment identified potential modes of failure as: transient event, structural failure, and seismic event. The potential consequences of failure are loss of water supply to the SFPUC Regional Water System, loss of water for power generation, erosion and undermining of adjacent infrastructure, damage to downstream facilities and infrastructure, and downstream safety hazard.

Failure of the Penstock will cause flooding, jeopardizing the safety of HHWP employees in Moccasin, and will result in damage to Moccasin facilities.
.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The budget and schedule are increased significantly due to the assumed scope change from rehabilitating the existing penstocks to constructing a new drop shaft, a tunnel and above grade pipes.

SCOPE: 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.

PROJECT DESCRIPTION: 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.

ASSETS: Moccasin Dam
Justification
This project is intended to ensure water quality, reliable water delivery, and dam safety.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Environmental Stewardship.

Operating Impact
Moccasin Dam is in satisfactory condition; however, the spillway is undersized and is not capable of passing the updated design flood that resulted from the March 2018 storm. The dam is fit for service; however capital investment is required to increase the spillway capacity of the facility. Currently the California Division of Safety of Dams has imposed maximum reservoir elevation operating restrictions, limiting the use of flashboards on the spillway. Use of these flashboards increases storage capacity during maintenance and construction projects (e. g., Mountain Tunnel Rehabilitation). Following completion of this project, the California Division of Safety of Dams will remove current elevation restrictions, increasing operational flexibility.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The change in budget and schedule is a result of findings from an updated engineering study of the conceptual layout with higher spill crest to provide additional operational and storage flexibility. The higher cost and extended schedule reflected a better definition of the project scope, site constraints, seasonal and operational limitations, more extensive environmental approval, and additional escalation.

SCOPE: HHWP owns about 40 miles of overhead electrical distribution lines in areas designated by California Public Utilities Commission as "High Fire Threat Zones." HHWP has evaluated prevention, mitigation, and response strategies to mitigate the threat of wildfire posed by overhead electrical distribution lines. This project will deliver electric distribution system capital improvements to reduce wildland fire risk on the HHWP Project. Projects will include reconductoring, increasing safe-clearance distances, undergrounding, and adding alternative power supplies at some locations to reduce HHWP's overhead electrical line footprint.

PROJECT DESCRIPTION: The program will include inspections, condition assessments, studies, designs, renewals and replacement, and construction of new microgeneration assets.

ASSETS: Represented asset families include transformers, circuit breakers, capacitors, switches, and disconnects; poles, cross-arms, guy wires, and anchorages; fuses, surge arrestors, insulators, and conductors; and SCADA.

Justification
Due to recent wildfires in California, there is an industry shift to address risks associated with power distribution lines. HHWP will construct projects to reduce the probability of wildfire events caused by HHWP's power distribution system.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, and Environmental Stewardship.

Operating Impact
Wildfire threatens the Hetch Hetchy project area and neighboring lands. The objective of this project is to reduce the risk of catastrophic wildfires resulting from HHWP's electrical lines and equipment. Uncontrolled wildfire presents a safety risk to staff and the public, and could potentially limit HHWP's ability to deliver water and generate power.

SCOPE: The project will repair a failed section of ramp and improve the remaining O'Shaughnessy boat ramp/dock to provide reliable all- season access to the reservoir for HHWP Operations and National Park Service Law Enforcement activities.

PROJECT DESCRIPTION: Assess the condition of the existing access road, boat ramp, and floating dock; develop an alternatives analysis and preferred recommendation; design and permit improvements; and construct the permitted designs.

ASSETS: Represented asset families include Hetch Hetchy Reservoir boat ramp, boat ramp access road, boat dock, and anchorage system.

Justification
The existing boat ramp is a one-way, steep, narrow, gravel, single-lane access road and ramp connecting the reservoir with the main service road. The access road and ramp are used to place and retrieve boats, maintain the boats, and launch the boats year-round. The boat ramp surface and retaining walls (gabion baskets) have failed, resulting in difficult access for personnel to safely traverse either in single vehicles or when backing a trailered boat along the road.

Water Level of Service Goal(s) Supported: Drinking Water Quality.

Operating Impact
The all-season boat ramp is necessary to access the reservoir to perform water quality monitoring and sampling to meet regulatory requirements. The boat ramp is also required for law enforcement to access the reservoir to enforce National Park security and regulatory requirements for the reservoir and tributaries.

SCOPE: The objective of this project is to assess the current condition of Mountain Tunnel and to complete urgent interim repairs to reduce the risk of tunnel lining failure until completion of the long-term Mountain Tunnel Improvements project in 2026.

PROJECT DESCRIPTION: The project consists of tunnel inspection in 2017 to update the Condition Assessment conducted in 2008, and short-term repairs in 2017 and 2018-19 to reduce the risk of failures in the concrete lining.

ASSETS: Mountain Tunnel.

Justification
This project was approved in an earlier CIP, and no funding is being requested in this plan. This project is in the closeout phase.

A catastrophic failure is possible with continued tunnel lining degradation. The likely type of anticipated failures are "local collapses," which would not impact power generation but would create water quality events in terms of turbidity in the water supply. The likelihood of localized collapses is moderate to high. Depending on the configuration of the system, this type of event could interrupt the deliveries from the Tuolumne River to the Regional Water System.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, and Sustainability.

Operating Impact
Depending on the configuration of the system, a "local collapse" could interrupt delivery of Tuolumne River to the SFPUC water customers.

Continual degradation of the asset could lead to a catastrophic failure.

SCOPE: 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" (AECOM WRE JV, July 2020). 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.

PROJECT DESCRIPTION: 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 (as noted in the 2020 AAR provided by AECOM). 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.

ASSETS: Moccasin Engineering and Records Building.

Justification
Staff currently work in trailers that are beyond their useful life and require frequent repairs. A permanent building is needed to provide adequate offices to meet long-term needs.

Water Level of Service Goal(s) Supported: Regional Delivery Reliability.

Operating Impact
Disrepair of existing modular facilities has led to reduced efficiency and potentially unsafe work environments. Deteriorated and cramped facilities do not attract skilled workers who are necessary to meet succession planning objectives. Additionally, maintaining access to information archives is a core function to meet operational objectives. Efficient recovery of documents such as construction contracts, as- builts, and O&M manuals, is important for ongoing operations, maintenance, and capital project execution.

Budget Change Yes Schedule Change Yes Scope Change Yes Reason for Change
The change in budget is a result of increased building square footage due to needed space. However, the schedule duration has been decreased following evaluation of the required construction duration.

SCOPE: Deliver capital improvement projects to sustain the reliability of HHWP's water conveyance assets from the reservoir intake structure/tower or dam's isolation valve to the powerhouse turbine isolation valves. Water is conveyed from upcountry reservoirs to the hydroelectric powerhouses via a network of tunnels, pipelines, penstocks, and canals, through valves, gates, portals, penstocks, and reservoir bypasses. NOTE: this project addresses reliability improvements for water conveyance from Eleanor, Cherry, and O'Shaughnessy reservoirs to Kirkwood and Moccasin Powerhouses. The R&R Water Conveyance Life Extension (Water), the R&R Water Conveyance Life Extension (Power), and the SJPL Life Extension Project address reliability improvements for other water conveyance assets on the HHWP Project.

PROJECT DESCRIPTION: HHWP has developed a program to extend the life of water conveyance assets prior to wholesale replacement. The program will include inspections, condition assessments, design, environmental evaluations, and construction, when appropriate, to sustain the reliability of water conveyance assets with capital improvements.

ASSETS: Examples of facilities classified as joint funded water conveyance assets include Canyon Tunnel and adits; Canyon Portal; Mountain Tunnel Headgates; Early Intake Bypass; Mountain Tunnel Diversion Access at Early Intake; Mountain Tunnel shafts and adits; South Fork Crossing and adits; Priest Reservoir Bypass; overflow shafts and surge shafts; sand traps; valves, gates, and actuators; and power systems.

SCOPE: HHWP owns assets in areas designated by Cal Fire as "High Fire Threat Zones." This project will mitigate the risk posed by uncontrolled wildfire to "Joint" assets by constructing fuel breaks near HHWP facilities. This project does not fund annual vegetation management plans.

PROJECT DESCRIPTION: The project includes the construction of fuel breaks and fuels reduction projects adjacent to HHWP facilities to provide protection of "Joint" assets.

ASSETS: HHWP Right of Way and facilities classified as "Joint" assets.

Justification
Shaded fuel breaks act as a defensible landscape to reduce fire speed and severity and to improve suppression by ground and air fire crews. Fuel breaks accomplish this by controlling fire behavior by reducing ladder fuels (fuels low to the ground that can cause the fire to "ladder" up trees and vegetation and spread across treetops); opening up the forest canopy; and reducing ground fuels. Fuel breaks are designed not to control a fire, but to provide points of access to control the flanks of a fire and provide possible backfire action in the face of an advancing fire head.

Water Level of Service Goal(s) Supported: Drinking Water Quality, Regional Delivery Reliability, Water Supply, Environmental Stewardship, and Sustainability.

Operating Impact
Hetch Hetchy Water and Power's wildfire mitigation projects will vary by asset, location and terrain. Wildfire is continuing to become more prevalent in California, requiring additional resources to mitigate risks and maintain operations.

Description
SCOPE: 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.

PROJECT DESCRIPTION: Construction of a new 9,000 SF Warehouse within the Moccasin campus to store large equipment and critical spare components for the Hetch Hetchy Water and Power System. The building will include office space for warehouse staff including records retention for warehouse and materials documentation.

ASSETS: This project will result in a new asset (Moccasin Warehouse Building).

Justification
A new warehouse is necessary to store critical spare equipment for the safe reliable operation of the Hetch Hetchy Water and Power system. The Old Moccasin Powerhouse that was used for storage of these critical spares is no longer suitable for this purpose due to the hazardous materials within the building and the structural deficiencies that are present.

Operating Impact
Impact to safe reliable operation of Hetch Hetchy Water and Power assets if critical spare equipment is not available due to lack of suitable warehouse storage.

Description
A significant part of the SFPUC's Information Technology (IT) infrastructure was implemented when headquarters moved to 525 Golden Gate Avenue in 2012. Much of the infrastructure implemented in 2012, which includes networking, telephony, conference room A/V equipment, etc., has surpassed its useful life. As a result, the likelihood of failure, not to mention cybersecurity risk, increases with the aging infrastructure. The purpose of this request is to fund the replacement, upgrade, and improvement of critical IT components/systems to mitigate these risks and provide higher levels of efficiency, reliability, and security. The Capital Plan request is comprised of the following projects, each focused on a specific area of IT infrastructure:

1. Network Infrastructure Upgrade

2. Server Infrastructure Upgrade

3. SCADA Infrastructure Upgrade

4. Phone Migration

5. 525GG Conference Room Refresh

6. Cybersecurity Improvements

7. SFPUC.GOV Migration

8. Maximo Upgrade

9. Application Enhancements (ServiceNow, GIS & Data Maturity)

10. Questica Implementation
Justification
Much of the current IT Infrastructure has surpassed its useful life. As a result, the likelihood of failure and cybersecurity risk, increases with the aging infrastructure. Upgrade, enhancement, or replacement of critical ITS Infrastructure components is needed to ensure uninterrupted, reliable, and secure technology resources are available to the entire organization.

Operating Impact
Water, Wastewater and Power increasingly relies on IT infrastructure to perform day-to-day operations. Failure of IT Infrastructure can impair the SFPUC's ability to provide water, power and properly treat wastewater, which can lead to risk in the areas of water quality/environmental, public health and safety.
