Are side flares required at curb ramps?
The ADA Standards do not require that curb ramps have side flares, but limit the slope (1:10 max.) where they are provided. Side flares are advisable where pedestrian traffic may cross runs to prevent tripping hazards. Side flares are essential in alterations when space for a top landing (36” deep min.) is not available; in this instance, side flares (1:12 max. slope) are necessary to accommodate wheelchair maneuvering that will partially occur at flares in the absence of full landing space at the top unless a parallel-type curb ramp is provided.
