36 CFR Part 1191 ABA Accessibility Guidelines, Outdoor Developed Areas - Preamble
1017.2 Surface
This section requires the surface of trails, passing spaces, and resting intervals to be firm and stable. A firm trail surface resists deformation by indentations. A stable trail surface is not permanently affected by expected weather conditions and can sustain normal wear and tear from the expected uses between planned maintenance.
