24th and Lilac

Supervisor Jackie Fielder, I am writing to you regarding the critical safety concerns at the intersection of 24th and Lilac in District 9. City records show 49 injury collisions within 150 meters of this intersection in the last five years, including 1 fatal collision. This figure covers a 150-meter radius, while the Danger Index grade is computed over a tighter 80-meter core, so these two figures are measured over different areas and should not be expected to reconcile. In the last three years, there have been 303 street-condition 311 reports at this location, counting street defects, sidewalk and curb, signs, streetlights, and blocked sidewalks only. This intersection shows more reported harm than 99 percent of San Francisco intersections, earning it a grade F on the Danger Index. No exposure normalization: the index ranks reported harm, not risk per crossing. City records document numerous 311 reports and pedestrian crossing collisions relating to faded or sub-standard crosswalk markings, although a visual audit did not find this in the photograph. City records also document numerous 311 reports relating to inadequate street lighting, although a visual audit did not find this in the photograph. Furthermore, city records document numerous 311 reports relating to curb or sidewalk in poor condition, although a visual audit did not find this in the photograph. I urge you to advocate for funding Continental crosswalks, corner daylighting, and a leading pedestrian interval at 24th and Lilac. These improvements are estimated to cost $250,000 to $350,000, an order of magnitude, and could be funded through the Caltrans Highway Safety Improvement Program (HSIP). Thank you for your attention to this vital matter. A resident of District 9
