Abstract:
Designing slopes at the maximum limits required for compliance with the Americans with Disabilities Act (ADA) often results in unnecessary rejections of constructed sidewalks and ramps. To accommodate for the accuracy of the inspection tool and the effects of local surface roughness, the ASCC Technical Committee recommends that designers specify maximum slopes that are slightly less than the ADA requirements. This article provides the committee’s recommendations for specifying and measuring slopes for walks and ramps.
