Mission and Ruth

Dear Supervisor Chen, I am writing to you as a concerned resident of District 11 regarding the critical safety issues at the intersection of Mission and Ruth. City records document 53 injury collisions, including one fatal incident, within 150 meters of this intersection over the last five years. This figure covers a 150-meter radius, while the Danger Index grade is computed over a tighter 80-meter core, so the two figures are measured over different areas and a reader should not expect them to reconcile. This intersection shows more reported harm than 99 percent of San Francisco intersections, earning it a grade F on the Danger Index. No exposure normalization: the index ranks reported harm, not risk per crossing. Over the past three years, there have been 60 street-condition 311 reports at this location, covering street defects, sidewalk and curb issues, signs, streetlights, and blocked sidewalks. City records show 311 reports: 3 in the last 12 months regarding pedestrian crossing collisions, and 9 over five years specifically relating to faded or sub-standard crosswalk markings, although a visual audit did not find this in the photograph. City records also show 311 reports: 4 in the last 12 months relating to curb or sidewalk in poor condition, though a visual audit did not find this in the photograph. While no recent press coverage was found for this corner, documented press coverage of safety problems at this intersection goes back at least 12 years, to 2014, representing the earliest coverage we can find. I urge you to fund Continental crosswalks, corner daylighting, and a leading pedestrian interval at this location. The estimated cost for these improvements is in the order of magnitude of $250,000 to $350,000, potentially through the Caltrans Highway Safety Improvement Program (HSIP). Thank you for your attention to this urgent matter. Sincerely, A resident of District 11
