Clarendon Quick-Build Share this: Facebook Twitter LinkedIn Project Introduction Clarendon Quick-Build is a transportation safety improvement project along Clarendon Avenue from Johnstone Drive to Laguna Honda Boulevard. The project proposes a road diet (reducing vehicle travel lanes to one lane in each direction), safety treatments at pedestrian crosswalks, and the addition of a crosswalk and a rectangular rapid flashing beacon at Dellbrook (Palo Alto Avenue). The Clarendon Quick-Build project is following behind a SF Public Works repaving project. SFMTA timeline will be dependent upon completion of repaving work. T he proposed changes use a new paint or striping to create the single lane configuration. No concrete barriers will be added to the roadway.

In San Francisco, the High Injury Network shows that 68% of severe and fatal collisions occur on just 12% of city streets. Between October 2018 and September 2023, there were seven reported injury collisions on Clarendon Avenue between Laguna Honda Boulevard and Johnstone Drive. Participatory Budgeting The SFMTA will be installing a ne w crosswalk, curb ramps, and a rectangular rapid flashing beacon (RRFB) to facilitate the trail crossing at Clarendon Avenue and Dellbrook (Palo Alto Avenue). This work is anticipated to be built before the SFPW repaving project starts. Funding for this new crosswalk and beacon is a result of the D7 2019 participatory budget process. Cross section of proposed single vehicle travel lane road configuration: Traffic speeds have been a primary factor in injury collisions on Clarendon Avenue. By installing a single lane in each direction and adding edge lines, the roadway is visually narrowed, and drivers tend to drive slower compared with similar roadways with two lanes. Right-sizing the roadway will also match the one-lane configurations that feed Clarendon Avenue on both ends: east of Johnstone Drive and at Laguna Honda Boulevard.
