Dear Supervisor Chen, I am writing to you as a resident of District 11 regarding urgent safety concerns at the intersection of Alemany and Ocean. This intersection shows more reported harm than 91 percent of San Francisco intersections, earning a grade D on the Danger Index. Please note, this index ranks reported harm, not risk per crossing, as it lacks exposure normalization. City records document 43 injury collisions within 150 meters of this intersection in the last five years, including one fatal collision. This count 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. In the last three years, 81 street-condition 311 reports were filed for this location, specifically for street defects, sidewalks, curbs, signs, streetlights, and blocked sidewalks. While no recent press coverage was found, documented coverage of safety problems at this intersection goes back at least 12 years, to 2014, representing the earliest coverage we can find. An automated visual audit observed faded or sub-standard crosswalk markings in a Street View photograph. City records corroborate this with one 311 report in 12 months and two pedestrian crossing collisions in five years. The audit also observed a vehicle turning conflict zone, which city records corroborate with two pedestrian crossing collisions in five years. I urge your support for funding critical safety upgrades: Continental crosswalks, corner daylighting, and a leading pedestrian interval. An estimated $250,000 to $350,000 for these improvements could be sought through the Caltrans Highway Safety Improvement Program (HSIP). Thank you for your attention to this vital community safety matter. Sincerely, A resident of District 11
