It is composed of representatives of disability groups, the design professions, building code organizations and federal enforcement agencies. Under the Americans with Disabilities Act (ADA), the Access Board is charged with recommending accessibility guidelines to federal enforcement agencies for all issues governed by the ADA. Once the Access Board recommendations are adopted by the Department of Justice (DOJ), the guidelines serve as the basis for enforceable standards for public agencies subject to the ADA and the Architectural Barriers Act (ABA); and WHEREAS, in July of 2004, the Access Board published proposed accessibility standards to update the standards adopted by the DOJ in 1994. The proposed guidelines represent the cumulative efforts of the Access Board and a broad cross-section of interested parties. After adoption, the standards were published for an extended period for public review and comment before final publication by the Access Board; and WHEREAS, before publishing the final guidelines, the Access Board reviewed over 2,500 comments received during the public comment period and incorporated many of these recommendations into the guidelines. The proposed guidelines have now been accepted by the DOJ and published as an Advanced Notice of Proposed Rule Making (ANPRM). They are now undergoing an additional period of public review and comment; and WHEREAS, the first Americans with Disabilities Act Accessibility Guidelines (ADAAG) were adopted by the DOJ in 1994 and have served as guidance for the City in all of its construction standards. The proposed changes to existing City standards regarding curb ramp design are consistent with those guidelines and also incorporate some recommendations from the Access Board's proposed ADA/ABA Accessibility Guidelines and draft Public Rights-of-Way guidelines; and WHEREAS, the Access Board's recommendations are not yet enforceable regulations under the ADA. Nevertheless, staff recommends the City incorporate some of the proposed changes now in anticipation of the various federal agencies (including DOT and DOJ) ultimately approving the Access Board's recommendations.
