Pedestrian Access Route (Sidewalk)

  • Is the continuous clear width at least 4 ft (48 in), exclusive of curb? *
  • Is the running slope no steeper than the general grade of the adjacent roadway? *
  • Is cross slope 2.0% (1:48) maximum? *
  • Are surface changes in level 1/4 in or less (or beveled up to 1/2 in)? *
  • Measured cross slope (%)

Curb Ramps

  • Is the ramp running slope 8.3% (1:12) maximum? *
  • Is a level turning space / landing provided (min 4 ft x 4 ft, 2% max slope)? *
  • Is the ramp clear width at least 4 ft (48 in)? *
  • Are counter/flare slopes 10% (1:10) maximum where a pedestrian can walk across the flare?

Detectable Warnings

  • Are truncated dome detectable warning surfaces present at the back of curb / flush transitions? *
  • Do detectable warnings extend the full width of the ramp and contrast visually with the surface? *
  • Photograph detectable warning installation

Crossings & Signals

  • Is the crosswalk cross slope within limits (2% at yield/stop crossings, 5% at signalized/midblock)?
  • Where pedestrian signals exist, are Accessible Pedestrian Signals (APS) with audible/vibrotactile indication provided?
  • Are pushbuttons reachable and mounted per PROWAG height/location requirements?
