Public Works oversees the maintenance of 865 miles of streets. Without regular resurfacing treatments, a street could end up costing the City four times more over the course of its life cycle. San Francisco uses the industry standard rating scale called the Pavement Condition Index (PCI) to score its streets. Public Works’ goal is to achieve and maintain a PCI of 75, which is considered “good” condition, however the PCI is projected to drop to 74 during this 10-year cycle given the funding constraints posed by the COVID-19 emergency.
The estimated cost to achieve and maintain a PCI of 75 is $1 billion over the next 10 years. Funding towards this need includes $31.5 million from the 2020 Health and Recovery G.O. Bond, $60 million from FY2023 and FY2024 Certificates of Participation, $256 million from the General Fund, and $474 million from a combination of federal, state, and other local sources.

The Capital Plan provides a strategy for the maintenance and renewal of 371 street structures including retaining walls, stairs, bridges, viaducts, tunnels, underpasses, and overpasses, plus numerous guardrails throughout the City. Work performed under this program includes general maintenance and major repairs of city street structures to maintain safety, proper operations of moveable bridges, and minimize long-term renewal costs. For this Plan, two major projects in this category include the Islais Creek and 4th Street bridges. The Islais Creek Bridge Rehabilitation project will include bridge machine equipment and system repair and upgrades, bridge deck and fender system replacement, bridge painting, and other damage and corrosion repairs. Proposed work on the 4th Street Bridge may include alterations and repairs to the south approach, modifications to structural steel bridge members, realignment of light rail tracks, and adjustment of counterweights.
The estimated cost for the Islais Creek Bridge project is $102.6 million, with $11.8 million being funded by the General Fund, and $90.8 million from a Federal grant. The estimated cost for the 4th Street Bridge project is $24.6 million, with $2.8 million being funded by the General Fund, and $21.8 million from a Federal grant.
The estimated cost for other street structure maintenance is $33.2 million over the next 10 years. Given anticipated funding constraints, the Plan allocates $8.2 million from the General Fund towards this need, acknowledging that extraordinary circumstances due to COVID-19 may make this challenging. PW has also identified an additional $37.7 million in Street Structure enhancement needs.

Upgrades to dams and reservoirs will meet the Water Levels of Service and Power Operational Objectives; funding is included for O’Shaughnessy Dam to address deficiencies of the existing outlet works system, including the drum gates and release system through to Canyon Tunnel, the Tuolumne River, and Moccasin Dam. The Mountain Tunnel project will address deterioration in the concrete lining of the tunnel for continued reliability. Roads and bridges will make replacements and improvements as recommended in condition assessment reports and road improvements program to keep up access to Hetch Hetchy Water and Power facilities. Utilities projects will maintain the power distribution system in a state of good repair consistent with utility best practices to ensure 24/7 power.
The cost of SFPUC’s Hetch Hetchy Water and Power – Joint Infrastructure renewal and replacement projects is approximately $594.2 million through FY2031. These assets are jointly funded by Water (45%) and Power (55%) sources. 

There are more than 80 miles of major sewers that have been in service for 100 years or more and are at the end of their useful life. This project includes cleaning and inspection of large diameter sewers, transport/storage boxes and collection system discharge/overflow structures. The results of the inspection program will inform the Renewal and Replacement Spot Repair and Collection System Sewer Improvements Programs (SSIP), as well as the SSIP sewer repairs. This project is a part of the on-going data gathering necessary for the Wastewater Enterprise Collection Systems Asset Management Program.
The cost of SFPUC’s Collection System/Condition Assessment Project is approximately $115.1 million through FY2031.

This program maintains the existing functionality of the sewage collection system and includes planned and emergency repairs and replacement of structurally inadequate sewers. Failure of the collection system will reduce the City’s ability to handle and dispose of wastewater and stormwater which can lead to public health, safety and environmental risks, and non-compliance with the State discharge permit. Projects are identified utilizing an asset management approach which factors in physical condition, age, location, risk, public safety, paving schedule, and other factors. This program allows for the renewal and replacement of approximately 15 miles of sewer per year.
The cost of SFPUC’s Collection System/Sewer Improvement is approximately $1.07 billion through FY2031.
