Polk Street is a thriving neighborhood and commercial corridor that serves an important transportation function for San Francisco. It also has some of the highest pedestrian and bicycle collision rates in the City. On average, one person walking and one person biking are hit by a vehicle each month on Polk Street (122 in a five-year period).
For years, Polk Street has been the site of many traffic-related injuries and the corridor is currently on San Francisco’s Vision Zero High Injury Network. This network represents 12 percent of San Francisco’s surface streets and is where injuries, including severe and fatal injuries, are most concentrated.
San Francisco's Vision Zero policy calls for eliminating traffic-related fatalities by 2024.
The corridor is not only the designated street for the #No. 19 Muni bus line; it also is a preferred north-south bicycle route due to its flatter terrain. Polk Street also is a popular place for people to walk.
The Polk Streetscape Project was designed to enable safe access for all road users of all ages and abilities. Through community input and technical evaluation, the proposed design includes corridor-wide safety improvements and additional streetscape amenities at key locations.
Partnering on the project are San Francisco Public Works, San Francisco Planning Department, the San Francisco Municipal Transportation Agency and the San Francisco Public Utilities Commission.
The Polk Streetscape Project aims to increase safety for people walking and biking on Polk Street, as well as improve the efficiency of transit on the corridor. This project will build on Polk Street's vibrant commercial character by improving safety and transportation choices.
Upcoming improvements on Polk Street between Beach and McAllister streets and nearby alleyways will include repaving, street base repair, sidewalk corner bulb-outs, to shorten the crossing distance, ADA-compliant curb ramp upgrades, Muni bus stop optimization; such as bus stop consolidation or relocation, bus bulb-outs for easier boarding, and left and right turn lanes to improve traffic flow, raised cycle tracks, green bike lanes, sewer replacements, water line replacement, traffic signal upgrades, high visibility crosswalks, better visibility at crosswalks, commercial-loading improvements, landscaping, tree planting, street lighting and alley enhancements to Fern Alley, to enhance the pedestrian and bicyclist experience with the creation of a well-lit plaza atmosphere, widening of the existing sidewalk, decorative asphalt, raised crosswalks, traffic calming measures and planting of palm trees.
To help achieve these improvements, the design necessitates the removal of 106 parking spaces along the Polk Street corridor and 28 spaces on side streets.
SFMTA legislated parking and loading changes for Polk Street and these changes will be implemented after final paving is completed for each segment. The parking and loading changes to the Polk side streets north of California Street have been implemented and the remainder of side streets changes will occur later this spring. To see the final parking and loading changes on Polk Street and the cross-streets, please see the final traffic striping plan here.
With the upcoming Polk Street paving work, SFMTA is implementing new striping of travel lanes with new improved bikeway designs. Parking and loading changes will occur with the new striping, including the removal of all parking on the east side of Polk Street between Pine Street and McAllister Street and some removal of parking on the west side of Polk Street with improved commercial and passenger loading spaces to better accommodate the area's demand.
