U.S. Access Board A Summary of Accessibility Guidelines for Play Areas Page 25 When Ramps Are Required Ramps are required on composite structures with 20 or more elevated play components and must connect to at least 25% of the elevated play components. Ramps allow individuals who use wheelchairs and mobility devices to access elevated play components in composite play structures without transferring. This play area has more than 20 play components and provides ramp access to elevated play components. The ramp system, consisting of ramp runs and landings, must connect at least 25 percent of the elevated play components. The balance of the elevated play components required to be on an accessible route may be connected by the ramp system, or by a transfer system. Rise of a ramp is the amount of vertical distance the inclined or slanted surface ascends or descends. A ramp run is a length of a continuous sloped surface that is ascending or descending. For example, to reach a 12-inch high deck or platform, a designer could use a 12-foot ramp with the maximum 1:12 slope, or a 14-foot ramp with a less steeper 1:14 slope. Platform lifts, also known as “wheelchair lifts,” may be considered for providing access to elevated play components when appropriate. Where applicable, platformliftscomplyingwith ADA/ABA Accessibility Guidelines chapter 4 and applicable state and local codes are permitted as a part of an accessible route. Because lifts must be independently operable, owners and operators should carefully consider the appropriateness of their use in unsupervised settings. 42 what are the requirements for accessible routes?
