ADA Curb Ramp by Request Prioritization Criteria

Criteria for ADA Curb Ramp Selection

The first and principal criteria used in the curb ramp site selection is that the request be made by a person with a disability as defined by the Americans with Disabilities Act (ADA) or on behalf of a person with disabilities. Priority is given for providing access to one’s residence, place of work, government offices and facilities, places of public accommodations and routes to transit.  

 Below are the criteria considered when prioritizing curb ramp installation/repair requests:
