Play area ground surfaces must be compliant with the Americans with Disabilities Act (ADA). Play area surfaces can be made of several different materials. All of these surfaces still must be able to comply with the ADA Standards. The Standards have requirements for run slope, cross slope, gaps, damage, change in elevation, vertical clearance, resistance to rolling a manual wheelchair across the surface, and impact attenuation from a fall. Owners of play areas and playgrounds must inspect these installations often, depending on the surface material, to be sure compliance with the ADA Standards is met. Failure to maintain a playground in compliance with ADA Standards can expose the owner and operator of a playground to significant liability.
