accessibility standards for Federal outdoor developed areas 43 Resting Intervals [1016 8] Resting intervals are level areas that provide an opportunity for people to rest before con- tinuing along an ORAR. Resting intervals are required at the top and bottom of an ORAR section any time the running slope exceeds 1:20 (5 percent). Resting intervals may be provided within an ORAR or adjacent to an ORAR. When a rest- ing interval is within an ORAR, it must be at least 60 inches long and at least as wide as the widest section of the ORAR leading into it (figure 14). (1525 mm) 2% TO 5% MAX MIN SLOPE IN ALL 60" DIRECTIONS Figure 14—Length and slope requirements for resting intervals. When a resting interval is adjacent to an ORAR, it must be at least 60 inches long and at least 36 inches wide. A turning space that complies with section 304.2.3 of the ABA Stan- dards must be provided. The vertical alignment of the ORAR, turning space, and resting interval must be nominally planar (i.e., as flat as possible) so that all the wheels of a mobil- ity device touch the ground surface when turning into and out of the resting interval. When the surface of the resting interval is constructed of concrete, asphalt, or boards, the slope of the resting interval must be no steeper than 1:48 (2 percent) in any direction. When the surface of the resting interval is constructed of materials other than concrete, asphalt, or boards, slopes no steeper than 1:20 (5 percent) are allowed when necessary for drainage.
