8th and Howard

Dear Supervisor Dorsey, I am writing to express my serious concern regarding the intersection of 8th and Howard. This location 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 document 55 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. Additionally, there have been 274 street-condition 311 reports in the last three years, covering street defects, sidewalks, curbs, signs, streetlights, and blocked sidewalks. An automated visual audit flagged faded or sub-standard crosswalk markings in the Street View photograph. City records corroborate this, documenting 15 street-condition 311 reports in 12 months and 8 pedestrian crossing collisions in 5 years. The audit also flagged a vehicle turning conflict zone in the Street View photograph, which city records corroborate with 8 pedestrian crossing collisions in 5 years. City records further show 9 street-condition 311 reports in 12 months relating to curb or sidewalk in poor condition, though the visual audit did not find this in the photograph. I urge you to fund improvements including Continental crosswalks, corner daylighting, and a leading pedestrian interval. These are estimated to cost $250,000 to $350,000, order of magnitude, through the Caltrans Highway Safety Improvement Program (HSIP). Thank you for your attention to this critical safety matter. Sincerely, A resident of District 6
