It's been almost 2 years since accessibility standards became effective for trails on Federal land covered by the Architectural Barriers Act (ABA). Following the effective date, the Board published a guidebook to assist trail designers and operators when applying the provisions. This session will provide an overview of the federal trail provisions, highlighting some of the material in the new guidebook. A trail expert with the National Park Service, Flagstaff Area National Monuments will also offer some “on the ground experiences“ of applying the standards to newly constructed trails and the alteration of existing trails. Session participants are encouraged to submit questions in advance.
