An accessible curb ramp features a maximum running slope of 8.33 percent with a 6.67 percent minimum and a 6-inch length, bounded by a flush curb with detectable warning surfaces. The landing area requires a minimum dimension of 4 feet by 4 feet with a cross slope not exceeding 2 percent in any direction. A 3-foot wide gutter at the accessible ramp maintains a maximum 2 percent gutter cross slope. A 2-foot transition flanks the ramp assembly.
