Playgrounds
- Need a firm, stable outdoor route of travel, 44 inches wide minimum, to the edge or surface and associated elements including viewing and playing areas.
- Need to have accessible equipment by reputable manufacturer installed correctly.
- Need accessible surfacing (meeting ASTM F-1951-99 standard www.astm.org) to all accessible, ground-level components and parts of the play structure as defined in the Access Board Recreation Playground Rules.
- Accessible surfacing to the whole play structure and accompanying areas is preferred, including entry points from surrounding area to the play equipment area. This is necessary for social and physical integration.
- Accessible equipment and number of elevated components determine whether you will need a transfer platform or ramp. Access to all equipment, including using ramps instead of transfer platforms, may be preferred for elevated features.
- When using engineered loose fill material, curb cut style ramps into the play area provides an accessible route even when the material compresses and leaves an edge or drop off.
