Detectable Warning Specifications

AMERICAN COUNCIL OF THE BLIND
RESOLUTION 2011-06

SUMMARY:

1. This organization urges the Access Board to include in its proposed specifications for detectable warnings all of the following elements: 70 percent clear visual contrast from the adjoining walking surface, federal yellow, resiliency and/or sound difference on cane contact from the adjoining walking surface, the alignment of truncated domes on a square grid, and a depth of 36 inches of detectable warning surface in order to ensure detectability.

2. The Environmental Access Committee of the American Council of the Blind is hereby directed to provide public comments on the guidelines once they are released which will clearly articulate the position outlined in this resolution.

WHEREAS, the American Council of the Blind has long advocated for detectable warning surfaces on curb ramps, rail platforms and blended transitions; and

WHEREAS, reports and research studies sponsored by the U.S. Architectural and Transportation Barriers Compliance Board (Access Board), the U.S. Department of Transportation, Project ACTION and studies from Japan all agree that where a curb ramp or level curb pedestrian way exists, it is necessary to place a detectable warning strip immediately adjacent to the vehicular way in order to indicate the precise location of the danger for persons who are blind or visually impaired; and

WHEREAS, this work demonstrates that a detectable warning should have the following characteristics: 70 percent clear visual contrast from the adjoining walking surface, federal yellow, resiliency and/or sound difference on cane contact from the adjoining walking surface, the alignment of truncated domes on a square grid, and a depth of 36 inches of detectable warning surface in order to ensure underfoot detection; and

WHEREAS, this summer the U.S. Access Board plans to release for public comment proposed guidelines for public rights-of-way which will address detectable warning surface requirements for curb ramps, curb cuts, track crossings, hazardous vehicular areas, and reflecting pools; and

WHEREAS, unless these guidelines contain the specific elements enumerated above, they will not provide sufficient protection for people who are blind or have low vision;

NOW, THEREFORE, BE IT RESOLVED by the American Council of the Blind in convention assembled at the John Ascuaga Nugget Hotel Resort and Casino in Sparks, Nev. on the 15th day of July, 2011, that this organization urge the Access Board to include in its proposed specifications for detectable warnings all of the following elements: 70 percent clear visual contrast from the adjoining walking surface, federal yellow, resiliency and/or sound difference on cane contact from the adjoining walking surface, the alignment of truncated domes on a square grid, and a depth of 36 inches of detectable warning surface in order to ensure detectability; and

BE IT FURTHER RESOLVED that the Environmental Access Committee of the American Council of the Blind is hereby directed to provide public comments on the guidelines once they are released which will clearly articulate the position outlined in this resolution.

Adopted.

Marlaina Lieberg, Secretary
