Dear Supervisor Dorsey, I am writing to you as a resident of District 6 regarding urgent safety concerns at the intersection of Gough and Market. City records show 99 injury collisions within 150 meters of Gough and Market 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, 331 street-condition 311 reports, counting street defects, sidewalk and curb, signs, streetlights, and blocked sidewalks only, have been filed at this location in the last three years. 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. No visual audit findings are available for this corner. I request your support in funding Continental crosswalks, corner daylighting, and a leading pedestrian interval at Gough and Market. An estimated cost of $250,000 to $350,000, order of magnitude, could be covered through the Caltrans Highway Safety Improvement Program (HSIP). Investing in these improvements will significantly enhance pedestrian and traffic safety in our district. Thank you for your attention to this critical matter. Sincerely, A resident of District 6
