16 U.S.C. § 8482 — Trail inventory

(a) Assessment. Within 7 years after January 4, 2025, the agency in charge ("the Secretary concerned") must (1) fully assess high-priority trails, chosen under subsection (b), on the federal lands and waters it manages. The assessment must measure each trail's (A) average and minimum tread width; (B) average and maximum running slope (steepness going up); (C) average and maximum cross slope (steepness side to side); (D) tread type (the surface material); and (E) length. The agency must also (2) publish information about these high-priority trails online — with prominently displayed links — on the websites of each federal land management agency and its units and subunits. (b) Selection. The agency must choose which high-priority trails to assess by (1) consulting stakeholders, including veterans organizations and groups experienced in outdoor recreation for people with disabilities; (2) spreading the chosen trails out geographically in a fair way; and (3) selecting trails in no fewer than 15 units or subunits that it manages. (c) Inclusion of current assessments. The agency may, where practical, rely on assessments or data already gathered before January 4, 2025, instead of starting over. (d) Public information. (1) In general: Within 7 years after January 4, 2025, the agency must identify ways to replace signage and other public information — including web pages — about the high-priority trails covered by the assessment, staying consistent with the Architectural Barriers Act of 1968 and 29 U.S.C. § 794. (2) Tread obstacles: As part of the assessment, the agency may, where practical, include photos or descriptions of obstacles and barriers on the trail's surface. (e) Assistive technology specification. When publishing information about each trail, the agency must include public information about trails that do not meet Architectural Barriers Act accessibility guidelines but could still offer outdoor recreation to people with disabilities who use certain assistive technology.
