52 A SUMMARY OFACCESSIBILITY STANDARDS FOR OUTDOOR DEVELOPEDAREAS accessibility standards for Federal outdoor developed areas The wheelchair space must be positioned for a forward approach and provide knee and toe clearance under the table that complies with section 306 of the ABA Standards. Knee clearance must be at least 30 inches wide and 8 inches deep at 27 inches above the ground surface. Toe clearance must be at least 30 inches wide and 17 inches deep and extend at least 9 inches above the ground surface (figure 18). Knee and toe clearance are required to ensure that a person using a mobility device can sit close to a tabletop, regardless of the table’s design. If a table is constructed with one solid leg on each end, as opposed to an A-shaped frame or two individual legs on each end of the table that would allow the wheelchair to fit between, the toes of a person using a mobility device could hit the table leg. Section 902.3 of the ABA Standards requires that the tops of dining surfaces be between 28 inches and 34 inches above the floor or ground surface.
