accessibility standards for Federal outdoor developed areas 79 A SUMMARY OFACCESSIBILITY STANDARDS FOR OUTDOOR DEVELOPEDAREAS Viewing Areas Definition [F106.5] A viewing area is an outdoor space developed for viewing a landscape, wildlife, or other points of interest. Distinct Viewing Locations [F246.2, 1015.2, and 1015.3] Viewing areas often provide more than one distinct viewing location. For example, a viewing area can provide a distinct viewing location for observing a mountain range and another distinct viewing location for observing a river. Distinct viewing locations within a viewing area don’t have to be identified, but may be designated by signs or other markers. A clear ground space at least 36 by 48 inches that is positioned for either a forward or parallel approach must be provided at each distinct viewing loca- tion. One full, unobstructed side of the clear ground space must adjoin or overlap an ORAR or trail, as applicable, or another clear ground space. Each distinct viewing location must provide a viewing space that is adjacent to the clear ground space through which the point of interest may be viewed. The viewing space must be free and clear of obstructions between 32 and 51 inches above the ground and must extend the full width of the clear ground space.
