Cedar and Larkin

Dear Supervisor Sauter, I am writing as a District 3 resident regarding urgent safety concerns at the intersection of Cedar and Larkin. City data shows 51 injury collisions recorded within 150 meters of this intersection in the last five years. It is important to note 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. The location has received 285 street-condition 311 reports concerning street defects, sidewalks, curbs, signs, streetlights, and blocked sidewalks in the last three years. While no press coverage was found in a recent search window, press coverage of safety problems at this intersection goes back at least 9 years, to 2017, the earliest coverage we can find. City records document 19 street-condition 311 reports in 12 months, and 11 pedestrian crossing collisions in 5 years, relating to faded or sub-standard crosswalk markings, although a visual audit did not find this in the photograph. City records also show 12 street-condition 311 reports in 12 months relating to inadequate street lighting, which a visual audit did not find in the photograph. Furthermore, city records indicate 7 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, and could be secured through the Caltrans Highway Safety Improvement Program (HSIP). Sincerely, A resident of District 3
