The Plan proposes $1.2 billion in funding for Public Works renewal needs over the next 10 years, with $552 million coming from the General Fund, as shown in Chart 10.1. 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 repair, median maintenance, plaza inspection and repair, sidewalk inspection and repair, street structure repair, and street tree planting, establishment, and maintenance. The street resurfacing program is by far the largest of these, with a planned investment of $822 million over the next 10 years.
The SFPUC’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 noted above, SFPUC renewal projects are not included in the Service Area renewal curve as the General Fund does not fund the Enterprise Department's projects. For more information on SFPUC renewals, please see the narrative descriptions in the following pages.
|PW – Curb Ramp Inspection and Repair||This project complements the Curb Ramp Program (see Enhancement section below) with funding to inspect and repair detectable tiles on existing ramps.
The estimated cost for curb ramp inspection and replacement is $12 million over the next 10 years. The Plan recommends $3.5 million from the General Fund towards this need, acknowledging that extraordinary circumstances due to COVID-19 may make
|PW – Landscape Median Maintenance and Irrigation Repair||As San Francisco replaces more cement and concrete with green spaces, investment in maintaining these areas keeps them free of trash and promotes the health of plants. With more than 175 landscaped medians and open spaces across the city, irrigation systems require routine maintenance and repairs to prolong their useful lives and keep the landscaping in good condition. Healthy plants can also help reduce maintenance needs by out competing weeds.
The estimated cost for median maintenance is $161.2 million over the next 10 years. The Plan recommends $36.4 million from the General Fund towards this need, in addition to $36.0 million expected from the State, acknowledging that extraordinary circumstances due to COVID-19 may make this challenging. PW has also identified an additional $38.2 million in median enhancement needs.
|PW – Plaza Inspection and Repair Program||Public Works is responsible for maintaining plazas throughout the City, including Blanken Bayshore, Embarcadero, Hallidie, Harvey Milk, Justin Herman, Mechanics, Mendell, Organ Pavilion, and United Nations Plazas. 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 $5.2 million over the next 10 years. The Plan recommends $1.5 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 $12.6 million in Plaza enhancement needs.
|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 and Mapping executes the Sidewalk Inspection and Repair Program; its goal is to inspect and repair every block on a 25-year cycle. Finally, the Bureau of Street Mapping has a reactive program called the Accelerated Sidewalk Abatement Program, which inspects locations based on complaints and issues notices of violation to property owners to compel them to repair their dangerous sidewalks.
The estimated cost for sidewalk improvements and repair is $53.1 million over the next 10 years. The Plan recommends $14.5 million from the General Fund towards this need, acknowledging that extraordinary circumstances due to COVID-19 may make this challenging. An additional $24.2 million is expected from other local sources.
|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. 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.
|PW – Street Structure Repair||
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.
|PW – Street Tree Maintenance and Sidewalk Repair||Public Works is responsible for maintaining approximately 125,000 street trees. Proposition E of the November 2016 ballot set aside annual funding towards this need and 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.
The estimated cost for street tree maintenance and related sidewalk repair is $267.8 million over the next 10 years, of which $231.4 is funded by the General Fund through Proposition E.
