5th and Shipley

Dear Supervisor Dorsey, I am writing to you regarding the intersection of 5th and Shipley in District 6, a location of significant safety concern. The city has recorded 61 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. In the last three years, there have been 273 street-condition 311 reports at this location, counting street defects, sidewalk and curb, signs, streetlights, and blocked sidewalks only. An automated visual audit flagged faded or sub-standard crosswalk markings in the Street View photograph. City records corroborate this with 9 street-condition 311 reports in 12 months and 3 pedestrian crossing collisions in 5 years. The visual audit also flagged a vehicle turning conflict zone in the Street View photograph. City records corroborate this with 3 pedestrian crossing collisions in 5 years. City records show 21 street-condition 311 reports in 12 months relating to curb or sidewalk in poor condition, although the visual audit did not find it in the photograph. I urge you to fund Continental crosswalks, corner daylighting, and a leading pedestrian interval. This is 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 issue. Sincerely, A resident of District 6
