Outdoor Developed Areas: A Summary of Accessibility Standards for Federal Outdoor Developed Areas
Clear Ground Space [1011.2]
A clear ground space must be provided at each outdoor constructed feature. The technical requirements include specific provisions for the size, location, surface, slope, and openings in the clear ground space.
Exceptions [1011.2, Exceptions 1 and 2]—When individual outdoor constructed features are altered and the ground surface is not changed, the clear ground space is not required to comply with the specific provisions for surface and slope.
In alterations, when a condition for exception does not permit full compliance with a specific provision in the technical requirements for the clear ground space, the clear ground space must comply with the specific provision to the extent practicable. Additional information on the conditions for exceptions is provided in the section of this guide on the conditions for exceptions.
Size [1011.2.1]—The size of the clear ground space is based on the dimensions for maneuvering clearance in section 305.7 of the ABA Standards for clear ground spaces that are confined on all or part of three sides. Providing clear ground spaces that are larger than the minimum required sizes can make the outdoor constructed feature more independently usable by people with varied abilities.
Table 4 shows the minimum requirements for clear ground space sizes for each outdoor constructed feature. The location and orientation of the clear ground space is discussed under the applicable outdoor constructed feature.
