Curb ramp distribution
Geographic Unit of Analysis:
|Curb ramp distribution (2015)|
|Neighborhood||Total intersections||Intersections with ramp recorded by DPW||Percent of intersections with curb ramps|
|Financial District/South Beach||331||252||76.10%|
|Golden Gate Park||132||117||88.60%|
|South of Market||268||207||77.20%|
|West of Twin Peaks||722||579||80.20%|
For individuals with mobility issues, parents using strollers, or shoppers using utility carts, curb ramps are essential for independent travel, providing an accessible path onto and off of public sidewalks to public facilities, accommodations, transportation, shopping districts, health care facilities, etc. Because of this, the Access Compliance Section of the Office of the State Architect and State Department of Rehabilitation developed Title 24 Part II which is a building code specifying the requirements for making, among other things, sidewalks and intersections accessible. All City departments and private contractors doing work adjacent to angular curb returns are required to construct curb ramps according to Public Works standards and construction specifications which incorporate both federal and state disability construction codes. Unfortunately, not all curb ramps in San Francisco have been modified to meet these requirements and individuals traveling through neighborhoods lacking accessible curb ramps are at risk for injury when trying to cross at intersections with high curbs, or may be less likely to use active transportation to get to and from their destinations.
Overall, 77% of intersections in San Francisco have at least one curb ramp. The neighborhood with the lowest presence of curb ramps is Treasure Island, which has no curb ramps among its 147 intersections. Other neighborhoods with low curb ramp coverage include: Presidio, Lincoln Park, Twin Peaks, and Bayview/Hunters Point, wich all have 65% or fewer intersections with ramps. Conversely, Outer Richmond and Sunset/Parkside, both have 98% of intersections with at least one curb ramp. Other neighborhoods that also have 90% or more intersections with curb ramps include: Pacific Heights, Haight Ashbury, Lone Mountain/USF, Hayes Valley, and Inner Richmond.
The presence of curb ramps is likely influenced by the volume of constuction that has taken place in neighborhoods. As DPW's curb ramp program states: "All City departments and private contractors doing work adjacent to angular curb returns are required to construct curb ramps according to Public Works standards and construction specifications which incorporate both federal and state disability construction codes." http://www.sfpublicworks.org/curbrampprogram
Curb ramp data was obtained from the DPW curb ramp program and was mapped. Intersections with as least one ramp, were shaded green.
A standard four leg intersection would ideally have eight crub ramps (two for each crosswalk). However some intersections do not allow pedestrian crossing on all legs, due to safety concerns (examples include Fell St. & Gough St. and Franklin St. & Oak St.). Because of this challenge definining an accurate denominator for the number of curb ramps, this indicator does not illustrate the degree to which intersections are complete, with all necessary curb ramps in place. This indicator only illustrates whether an intersection has at least one curb ramp.
