Withdrawn Technical Assistance: Common ADA Errors and Omissions in New Construction and Alterations

[As of] December 21, 2017, the Department of Justice has withdrawn and, where applicable, removed from ADA.gov [this] technical assistance document. [This] document is outdated and does not fully reflect current law or has been replaced by a more up-to-date document. Withdrawal of a guidance document does not change covered entities’ legal responsibilities, as reflected in the ADA, its implementing regulations, and other binding legal requirements and judicial precedent. The Department will continue to fully and fairly enforce all laws within its jurisdiction, including the ADA.

Note: This document, portion of document or referenced document was published prior to the 2010 ADA Standards, and is still applicable.

Curb Ramps

Error/Omission:

Curb ramp that is located across a circulation path has steep unprotected side flares.

Result:

People walking across the curb ramp may trip and be injured. People who use wheelchairs can tip over if they accidentally roll over the non-flared sides.

Requirement:

4.7.5 Sides of Curb Ramps. If a curb ramp is located where pedestrians must walk across the ramp, or where it is not protected by handrails or guardrails, it shall have flared sides; the maximum slope of the flare shall be 1:10 (see Fig. 12(a)). Curb ramps with returned curbs may be used where pedestrians would not normally walk across the ramp (see Fig. 12(b)).
