This project was made possible in part by the San Francisco County Transportation Authority through a grant of Proposition K Local Transportation Sales Tax funds.
In October 2005, a community meeting was held to present traffic calming ideas to the community and to gather input about traffic conditions in the Inner Sunset project area. About the same time, surveys were mailed to residents and were made available on the internet as a means to collect more community input. That input helped to focus the direction of the project and guided the SFMTA in collecting speed and volume data.
A Community Working Group was then convened to discuss the community input and the data that was collected. From there a traffic calming plan was drafted. In September of 2006 that draft plan was presented at a community meeting and a general consensus was reached to move forward with the plan. From there, the Inner Sunset Draft Traffic Calming Plan (PDF) was approved by the SFMTA Board and implementation of the plan began in mid-2007. (Here is the funding/phasing plan (PDF) )
Phase 1: Speed humps. Two speed humps were installed on 6th Avenue – one on the block between Irving and Judah Streets and another on the block between Judah and Kirkham Streets. Initial construction was complete in June of 2007, but a subsequent inspection found that the humps were higher than City standards allowed. The humps were removed and reinstalled to meet City standards that were previously approved by the Fire Department are consistent with national guidelines.
Phase 1: Count-Down Signals. Count-down signals were installed at the intersections of 9th Avenue / Judah Street, 9th Avenue/ Irving Street and 7th Avenue/ Irving Street.
Phase 2: 4th and 5th Avenue Edge Lines. Edge lines were striped on 4th and 5th Avenues between Irving and Parnassus Streets. The intent of the lines is to move traffic away from pedestrians on the west side of the street and away from parked vehicles on the east side of the street, where sight lines are limited.
Phase 2: Lincoln Median Extensions. As part of the Lincoln Way paving project, the center median was extended to tighten the left turns from westbound Lincoln Way onto 4th, 8th and 12th Avenues. These median extensions should slow vehicles as they enter these residential streets. The median extensions are mountable so large vehicles can still make these left turns.
Phase 2: 7th Avenue Re-striping. A grant from the Bay Area Air Quality Management District funded the re-striping of 7th Avenue from Lincoln Way to Laguna Honda Boulevard, removing one of the southbound lanes. As part of this project, signals at the Irving, Judah, Kirkham and Lawton Street intersections have been re-timed. This project is ongoing and seeks to improve the flow of traffic in the northbound direction while also improving the safety of left turn movements. By improving the flow in the northbound direction, motorists will be encouraged to remain on 7th Avenue (the designated arterial) instead of cutting off onto parallel streets. On the blocks between Lincoln and Judah, there is now one lane in each direction with a center turn lane. On the blocks from Judah to Lawton, there is now a single wide lane in each direction. From Laguna Honda to roughly Moraga, one of the northbound lanes has now been converted to a center turn lane and a pedestrian island will be constructed in that lane at the Moraga crosswalk.

Phase 2: Pedestrian Islands. A grant from the Bay Area Air Quality Management District was secured to construct pedestrian islands at the intersections of 8th Avenue / Judah Street, 8th Avenue / Kirkham Street, 8th Avenue / Lawton Street, 5th Avenue /Judah Street and Warren / Locksley Streets. These islands are intended to improve pedestrian comfort and slow some turning movements at these locations without creating delays for Muni. Construction of these islands is complete.
Phase 2: Irving Street Bulb-Outs. Two grants (Regional Bicycle and Pedestrian Program and Transportation for Livable Communities) were secured to construct bulb-outs at one or two corners at the following intersections: 4th and Irving (1); 5th and Irving (2); 7th and Irving (2); 8th and Irving (2); 9th and Irving (1). These bulb-outs have been constructed.
Lincoln Way on the north. 9th Avenue to the west. Lawton to the south. 3rd Avenue to the east.
