6th and Mission

Dear Supervisor Dorsey, I am writing to you regarding the critical safety issues at the intersection of 6th and Mission in District 6. The city has recorded 94 injury collisions within 150 meters of this intersection in 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 a grade F on the Danger Index. No exposure normalization: the index ranks reported harm, not risk per crossing. City records show 436 street-condition 311 reports at this location in the last three years, counting street defects, sidewalk and curb, signs, streetlights, and blocked sidewalks only. Press coverage of safety problems at this intersection goes back at least 12 years, to 2014, which is the earliest coverage we can find. No press coverage was found for this corner in a recent search window. City records show 311 reports: 12 in 12 months and 22 pedestrian crossing collisions in 5 years relating to faded or sub-standard crosswalk markings, although a visual audit did not find it in the photograph. City records also show 311 reports: 6 in 12 months relating to inadequate street lighting, although a visual audit did not find it in the photograph. City records further show 311 reports: 13 in 12 months relating to curb or sidewalk in poor condition, although a visual audit did not find it in the photograph. I urge you to advocate for funding Continental crosswalks, corner daylighting, and a leading pedestrian interval at this location. An estimated cost of $250,000 to $350,000, order of magnitude, could be secured through the Caltrans Highway Safety Improvement Program (HSIP). Sincerely, A resident of District 6
