38 A SUMMARY OFACCESSIBILITY STANDARDS FOR OUTDOOR DEVELOPEDAREAS accessibility standards for Federal outdoor developed areas Clear Width [1016 3] The clear width of ORARs must be a minimum of 36 inches. The 36-inch-minimum clear width must be maintained for the entire ORAR and may not be reduced by gates, barriers, or other obstacles unless a condition for exception does not permit full compliance with the provision. ORARs don’t all necessarily have to be the same width. ORARs may be differ- ent widths, depending on their location. Consider the number of people who are likely to use the ORAR at the same time and how they will want to use it—single file or walking side-by-side. Two people using mobility devices need a clear width of at least 60 inches to pass each other on an ORAR. Consider providing a minimum clear width of 60 inches on ORARs that connect camping units with mobility features to important features, such as toilet and bathing facilities or water hydrants. Passing Spaces [1016 4] Where the clear width of an ORAR is less than 60 inches, passing spaces must be provided at intervals of at least 200 feet. Passing spaces must be: ¡ ¡ A minimum space of 60 by 60 inches or ¡ ¡ The intersection of two ORARs that provide a T-shaped space that com- plies with section 304.3.2 of the ABA Standards, where the base and the arms of the T-shaped space extend a minimum of 48 inches beyond the intersection (figure 12) Either of these configurations provides enough space for people using mobility devices to move to the side and let other people pass along the ORAR.
