     (a) Design and construction.  Each facility or part of a facility 
 constructed by, on behalf of, or for the use of a public entity shall 
 be designed and constructed in such manner that the facility or part  
 of the facility is readily accessible to and usable by individuals    
 with disabilities, if the construction was commenced after January 26,
 1992.                                                                 
     (b) Alteration.  Each facility or part of a facility altered by,  
 on behalf of, or for the use of a public entity in a manner that      
 affects or could affect the usability of the facility or part of the  
 facility shall, to the maximum extent feasible, be altered in such    
 manner that the altered portion of the facility is readily accessible 
 to and usable by individuals with disabilities, if the alteration was 
 commenced after January 26, 1992.                                     
     (c) Accessibility standards.  Design, construction, or alteration 
 of facilities in conformance with the Uniform Federal Accessibility   
 Standards (UFAS) (appendix A to 41 CFR part 101-19.6) or with the     
 Americans with Disabilities Act Accessibility Guidelines for Buildings
 and Facilities (ADAAG) (appendix A to 28 CFR part 36) shall be deemed 
 to comply with the requirements of this section with respect to those 
 facilities, except that the elevator exemption contained at section   
 4.1.3(5) and section 4.1.6(1)(k) of ADAAG shall not apply.  Departures
 from particular requirements of either standard by the use of other   
 methods shall be permitted when it is clearly evident that equivalent 
 access to the facility or part of the facility is thereby provided.   
     (d) Alterations:  Historic properties.  (1) Alterations to        
 historic properties shall comply, to the maximum extent feasible, with
 section 4.1.7 of UFAS or section 4.1.7 of ADAAG.                      
     (2) If it is not feasible to provide physical access to an        
 historic property in a manner that will not threaten or destroy the   
 historic significance of the building or facility, alternative methods
 of access shall be provided pursuant to the requirements of  35.150.  
     (e) Curb ramps.  (1) Newly constructed or altered streets, roads, 
 and highways must contain curb ramps or other sloped areas at any

 level pedestrian walkway.                                             
     (2) Newly constructed or altered street level pedestrian walkways 
 must contain curb ramps or other sloped areas at intersections to     
 streets, roads, or highways.
