4.4.4 Clear Floor or Ground Space.
A clear floor or ground space of 36 inches (915 mm) by 48 inches (1220 mm) shall be located at an end the bench with one side of the space adjoining an accessible route, outdoor recreation access route, trail, or beach access route. The long dimension of the clear space shall be roughly perpendicular to the length of the bench.
Locate the clear space to provide shoulder alignment between a person sitting on the bench and a person seated in a wheelchair occupying the clear space. Shoulder alignment generally can be achieved by positioning the back of the bench so it is 8 inches (200 millimeters) closer to the outdoor recreation access route, trail, or beach access route than the back of the required clear floor or ground space adjacent to the end of the bench.
The clear floor or ground space shall not overlap the outdoor recreation access route or trail.
