This Indicator measures the percent of curbs with curb ramps that are not modern, indicating that they are non-compliant. Modern curb ramps should have all the proper elements: low slope and cross-slope, adequate width, level top and bottom landings, a detectable warning surface, and they should be directional and clear of obstructions in the curb ramp area. This is a citywide Indicator that measures conditions for individuals with physical disabilities and limited mobility.
