19th and Judah

Dear Supervisor Wong, I am writing to express my serious concern regarding the safety of the intersection at 19th Avenue and Judah Street in District 4. City records indicate 19 injury collisions occurred within 150 meters of this intersection in the last five years. It is important to note this 150-meter radius differs from the 80-meter core used for the Danger Index, so these figures are not directly comparable. The intersection shows more reported harm than 96 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. The location has also generated 80 street-condition 311 reports in the last three years, counting street defects, sidewalk and curb issues, signs, streetlights, and blocked sidewalks. An automated visual audit flagged faded or sub-standard crosswalk markings in Street View. City records corroborate this with 311 reports: 5 in 12 months, and 4 pedestrian crossing collisions in 5 years. The audit also flagged a vehicle turning conflict zone, corroborated by 4 pedestrian crossing collisions in 5 years. Additionally, the audit observed curb or sidewalk in poor condition, which city records corroborate with 311 reports: 5 in 12 months. To address these documented hazards, I urge you to support funding for Continental crosswalks, corner daylighting, and a leading pedestrian interval at this intersection. An order of magnitude estimate for these improvements is $250,000 to $350,000, which could be secured through the Caltrans Highway Safety Improvement Program (HSIP). Thank you for your attention to this critical issue. A resident of District 4
