1. Accessible Trails
The Basics

2. Background – policy and agencies
Architectural Barriers Act (ABA) 1968 – Applies only to federal agencies (facilities paid for with federal funds)
Americans with Disabilities Act (ADA) – Applies to all government entities and private facilities that are public access
Americans with Disabilities Act Accessibility Guidelines (ADAAG) – Address the built or “bricks and mortar” environment
U. S. Access Board - Federal agency responsible for setting guidelines for accessible outdoor recreation environments
American Association of State Highway and Transportation Officials (AASHTO) – Sets guidelines for shared use paths as part of the transportation system

3. Background - philosophy
Accessibility requirements vary by individual situation (e.g., A strong wheel chair user and a parent pushing a stroller may require different design criteria to make a trail useable.)
Purpose of a trail should be kept in mind (e.g.,If the trail’s primary purpose is mtn. biking or horseback riding accessibility is not an issue.)

4. Guidelines
Apply to new or altered trail construction not to maintenance
Ten basic technical provisions:
Surface must be “firm and stable”
Clear tread width is a minimum of 36”
Openings in tread cannot exceed ½ inch and must be perpendicular
Protruding objects must be 80” above the tread (visual disabilities)
Tread obstacles cannot exceed 2 inches in height (some exceptions)
Passing space of at least 60” width every 1000 ft
Longitudinal slope of 5% for any distance, 8% for 200 ft, 10% for 30 ft
Resting intervals must be 60” in length and be at least as wide as trail leading to that spot
Edge protection not required but if provided minimum 3” high
Signage should be provided with distance of accessible segment

5. 4 Conditions for Departure
