On July 26, 1991 the Architectural and Transportation Barriers Compliance Board (Access Board) published the Americans with Disabilities Act Accessibility Guidelines (ADAAG). The ADA establishes accessibility requirements for new construction and alterations of State and local government facilities, and places of public accommodation and commercial facilities. As updated in the November 16, 1999 ADAAG Notice of Proposed Rulemaking, section 302.3 states that "openings in floor or

ground surfaces shall allow passage of a sphere not more than ½ inch (13mm) diameter...Elongated openings shall be placed so that the long dimension is perpendicular to the dominant direction of travel."
