NOT SENT TO ANY OFFICIAL
Dear Supervisor Mahmood, I am writing to you regarding the urgent need for safety improvements at the intersection of Breen and McAllister in District 5. City records document 64 injury collisions within 150 meters of this intersection in the last five years, including one fatality. This 150-meter radius differs from the tighter 80-meter core used for the Danger Index, so these figures are not directly comparable. Furthermore, 216 street-condition 311 reports, covering street defects, sidewalks, curbs, signs, streetlights, and blocked sidewalks, were filed for 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. It is important to note that this index ranks reported harm, not risk per crossing, as it lacks exposure normalization. To address these documented safety concerns, I urge you to advocate for funding Continental crosswalks, corner daylighting, and a leading pedestrian interval at Breen and McAllister. An estimated $250,000 to $350,000, order of magnitude, could be secured through the Caltrans Highway Safety Improvement Program (HSIP). These improvements are crucial for the safety of our community. Sincerely, A resident of District 5
