Dear Supervisor Mahmood, I am writing to you as a concerned resident of District 5 regarding the persistent safety issues at the intersection of Eddy and Larkin. City records show 111 injury collisions, including 2 fatalities, within 150 meters of this intersection over the last five years. This 150-meter radius differs from the 80-meter core used for the Danger Index grade, so these figures are not directly comparable. This intersection shows more reported harm than 99 percent of San Francisco intersections, earning an F grade on the Danger Index. It is important to note this index ranks reported harm, not risk per crossing, as it does not normalize for exposure. While recent searches found no press coverage for this specific corner, press coverage of safety issues at this intersection dates back at least nine years, to 2017. Additionally, there have been 284 street-condition 311 reports concerning street defects, sidewalks, curbs, signs, streetlights, and blocked sidewalks at this location in the last three years. An automated visual audit flagged a vehicle turning conflict zone in a Street View photograph, which city records corroborate with 10 pedestrian crossing collisions in the last five years. City records further document 6 street-condition 311 reports in 12 months and 10 pedestrian crossing collisions in 5 years related to faded or substandard crosswalk markings, even though the visual audit did not observe this in the photograph. City records also show 3 street-condition 311 reports in 12 months regarding inadequate street lighting, which the visual audit did not note in the photograph. Additionally, city records indicate 7 street-condition 311 reports in 12 months concerning poor curb or sidewalk condition, again not observed in the visual audit photograph. I urge you to advocate for funding for Continental crosswalks, corner daylighting, and a leading pedestrian interval at this intersection. An estimated cost of $250,000 to $350,000, order of magnitude, could be sought through the Caltrans Highway Safety Improvement Program (HSIP). Thank you for your attention to this critical matter. Sincerely, A resident of District 5
