49 Code of Federal Regulations (CFR) Parts 27 and 28 require that all recipients of federal-aid highway funds comply with Section 504 of the Rehabilitation Act of 1973. It states that "No otherwise qualified individual with a disability in the United States shall, solely by reason of his or her disability, be excluded from participation in, be denied the benefits of or be subjected to discrimination under any program or activity receiving federal financial assistance." 28 CFR 35 implements the Americans with Disabilities Act of 1990 (ADA), which extended the prohibition of discrimination on the basis of disability to all local agencies, including those that do not receive Federal financial assistance. ADA requirements differ for agencies with 50 or more full-time and part- time employees versus agencies with fewer than 50 full-time and part-time employees.
49 CFR Part 21 requires that all recipients of federal-aid highway funds comply with Title VI of the Civil Rights Act of 1964. 23 CFR Part 200 creates responsibilities for TxDOT to develop and implement an effective external monitoring program that necessitates Title VI reviews of cities, counties, consultant contractors, suppliers, universities, colleges, planning agencies and other subrecipients of federal-aid highway funds.
