Dore and Harrison

Dear Supervisor Dorsey, I am writing to you regarding critical safety issues at the intersection of Dore and Harrison in District 6. City records document 47 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, meaning the two figures are measured over different areas and should not be expected to reconcile. Additionally, 89 street-condition 311 reports, covering defects, sidewalks, curbs, signs, streetlights, and blocked sidewalks, were filed at this location in the last three years. This intersection shows more reported harm than 99 percent of San Francisco intersections, earning a grade F on the Danger Index. Please note that this index ranks reported harm, not risk per crossing, as there is no exposure normalization. The earliest press coverage of safety problems at this intersection we can find dates back at least 4 years, to 2022. No press coverage was found for this corner in a recent search window. No visual audit findings are available for this corner. I urge you to support funding for safety improvements. Specifically, I request your assistance in securing funding for Continental crosswalks, corner daylighting, and a leading pedestrian interval. These improvements are estimated to cost $250,000 to $350,000, an order of magnitude, and could be pursued through the Caltrans Highway Safety Improvement Program (HSIP). Thank you for your attention to this vital matter. Sincerely, A resident of District 6
