U.S. Access Board A Summary of Accessibility Guidelines for Play Areas Page 21 Ground-Level Accessible Routes Maximum Slope at Ground Level The maximum allowable slope for a ground-level accessible route is 1:16. Berms are sometimes used to provide access to elevated play areas. A berm may be a natural sloped surface that is present in a hilly play area site, or a ground-level route built with slopes. Designers are encouraged to consider edge protection and handrails on berms where there may be a drop-off. Remember the maximum slope of this “ground-level accessible route” is 1:16. However, handrails are not required on ground-level accessible routes. This is permitted since the handrails may become a safety hazard in the “use zone.” This play area provides a bermed accessible route. To accommodate a height change along the perimeter of a play area - like these rubber safety tiles placed on an asphalt surface - an allowable 1:12 slope is utilized for the transition at the boundary of the play area. 32 33 what are the requirements for accessible routes?
