The Plan proposes $1.3 billion in funding for Public Works renewal needs over the next 10 years, with $908 million coming from the General Fund, as shown in Chart 9.1. SFPUC renewal projects are not represented in this curve.
The General Fund streets and right-of-way renewal program includes street resurfacing, curb ramp inspection and replacement, median maintenance, plaza inspection and repair, sidewalk inspection and repair, street structure repair, and street tree planting, establishment, and maintenance.
The PUC’s renewal program includes sewer replacements, pump system rehabilitations, water storage upgrades, technology infrastructure improvements, and many other projects necessary to provide for San Francisco’s water, wastewater, and power needs. As with Enterprise departments covered in other chapters, PUC renewal projects are not included in the Service Area renewal curve. For more information on these projects, please see the narrative descriptions included in the following table.
|PW – Street Resurfacing and Reconstruction||
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. As approved by city officials and voters, Public Works’ goal is to achieve and maintain a Pavement Condition Index score (PCI) of 70. This target will take streets from the “at-risk” to a more cost-effective “good”.
The estimated cost to achieve and maintain a PCI of 70 is $816 million over the next 10 years. The Plan recommends fully funding this need, with $693 million coming from the General Fund, and the remainder from a combination of federal, state, and other local sources.
|PW – Curb Ramp Inspection and Replacement||
Title II of the Americans with Disabilities Act requires local entities to develop a transition plan specifically for curb ramps. The City is committed to improving curb ramps and providing accessible paths of travel for people with disabilities. This project complements the installation of new ramps (see the Enhancements section below for additional details) by ensuring sufficient funds for maintaining previously installed ramps.
The estimated cost for curb ramp inspection and replacement is $16 million over the next 10 years. Given funding constraints, the Plan allocates $9 million from the General Fund towards this need.
|PW – Median Maintenance||
As the City converts more paved areas into green space, Public Works needs capacity to maintain these areas to ensure that the investments last and that medians and other landscape spaces are kept in great condition. There are irrigation systems at 67 landscaped medians across the City.
The estimated cost for median maintenance is $147 million over the next 10 years. Given funding constraints, the Plan allocates $57 million from the General Fund towards this need, in addition to $50 million expected from the State.
|PW – Plaza Inspection and Repair Program||
Public Works is responsible for maintaining fourteen plazas throughout the City, including: Blanken Bayshore, Embarcadero, Hallidie, Harvey Milk, Justin Herman, Mechanics, Mendell, Organ, United Nations, Civic Center, Tutubi, McCoppin Hub, Bartlett, and Corbett Community Garden. These plazas require annual inspection to determine the extent of any repairs that may be required.
The estimated cost for plaza inspection and repair is $22 million over the next 10 years. Given funding constraints, the Plan allocates $13 million from the General Fund towards this need.
|PW – Sidewalk Improvements and Repair Program||
Public Works maintains sidewalks in three ways. First, the Bureau of Urban Forestry maintains sidewalks around city-maintained street trees. Second, the Bureau of Street Use & Mapping executes the Sidewalk Inspection and Repair Program; its goal is to inspect and repair every block on a 25-year cycle. Finally, Bureau of Street Mapping also has a reactive program called the Accelerated Sidewalk Abatement Program, which inspects locations based on complaints and issues notices of violation to property owners in order to compel them to repair their dangerous sidewalks.
The estimated cost for sidewalk improvements and repair is $37 million over the next 10 years. The Plan fully funds this need, with $14 million coming from the General Fund, and the remainder from the State, and other local sources.
|PW – Street Structure Repair||
The Capital Plan provides a strategy for the maintenance and renewal of 364 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 estimated cost for the Islais Creek Bridge project is $45 million, with $5.4 million being funded by the General Fund, and $39 million from a Federal grant. The estimated cost for the 4th Street Bridge project is $22 million, with $2.6 million being funded by the General Fund, and $20 million from a Federal grant.
|PW – Street Tree Planting, Establishment, and Maintenance||
By FY2018, Public Works will be responsible for maintaining approximately 121,000 street trees. Public Works will have the resources to maintain street trees on an average three-to-five-year cycle, inspect all street trees annually, and make sidewalk repairs on a similar cycle. Additionally, the City anticipates replacing approximately four percent of trees each year as a result of typical tree mortality, disease, or vandalism.
The estimated cost for street tree planting, establishment, and maintenance is $250.5 million over the next 10 years. The Plan fully funds this need, with $219.9 million from the General Fund, in addition to $30.6 million expected from State and other local sources.
|SFPUC Hetch Hetchy Water and Power – Mountain Tunnel Rehabilitation Project||Mountain Tunnel was constructed between 1917 and 1925, and has provided reliable water conveyance for nearly 90 years.

This program will provide upgrades to the Transmission System including pipeline inspection and repairs, valve replacements, metering upgrades, corrosion protection to extend the useful life of the pipelines, pump station upgrades and vault upgrades.
Included is $157 million funding for Pipeline Improvement Program over the next 10 years to replace or slip-line up to 10 miles of pipelines in densely populated areas to improve operational reliability and reduce liability.
|SFPUC Water – Regional Watersheds & Land Management||This program supports projects that improve and protect the water quality and ecological resources impacted by the siting and operation of PUC facilities. These projects include the repair, replacement, maintenance, or construction of roads, fences, or trails, the acquisition of easements and/or fee title of properties, and other ecosystem restoration or public access, recreation, and education projects.|
|SFPUC Water – Regional Water System Improvement Program (WSIP) Augmentation||Additional funding at Calaveras Dam and the Alameda Creek Diversion Dam is needed for unanticipated subsurface conditions and localized slope stability which will result in increases in rock support, shotcrete, and shale disposal work. The revised baseline schedule will still allow the dam embankment to be complete by fall 2018, which will allow filling of the reservoir to begin in the fall/winter 2018-19 as planned.|
|SFPUC Water – System Monitoring and Control||The System Control and Data Acquisition (SCADA) provides remote monitoring of pressure, flow, and valve position status at key locations throughout the distribution system. This project provides improvements to SCADA and to facilities that control and monitor San Francisco’s water distribution system. This program will also install fiber optic communications to critical facilities and security installations not completed under WSIP.|
|SFPUC Water – Water Storage Facilities||The PUC maintains 10 major water storage reservoirs and six storage tanks that range in age from 50 to 120 years old. The College Hill Reservoir supplies much of the eastern and northern areas of San Francisco, including Zuckerberg San Francisco General Hospital, the City’s trauma center. This project provides long-term funding for the renewal and rehabilitation of these reservoirs and tanks. Planning evaluation and geotechnical review were conducted and recommend that the outlet structure be replaced with a new 48-inch diameter steel pipeline with outlet valve facilities.|
