Red parking zones on approaches to crosswalks improve sight distance between pedestrians and approaching motorists and are recommended in the MUTCD for both controlled and uncontrolled intersections. In San Francisco, a 10 foot red zone can be painted on crosswalk approach legs. Longer red zones should be used at locations with a greater need for improved visibility due to unique sight distance, geometric, or other conditions.
In San Francisco, due to limited on-street parking supply and high demand, the practice is to evaluate each crosswalk location on a case-by-case basis to determine whether parking removal is appropriate or desired. Priority should be given to intersections with safety issues, existing project locations, and locations where staff is conducting safety reviews.
