DBE Program

It is the policy of the Solano Transportation Authority (STA) to ensure that Disadvantaged Business Enterprises (DBEs) shall have the maximum feasible opportunity to participate in the performance of contracts financed in whole or in part with STA funds. The STA and its employees shall not discriminate on the basis of race, color, sex, national origin, religion, age, or disability in the award and administration of STA contracts. It is the intention of the STA to create a level playing field on which DBEs can compete fairly for contracts and subcontracts relating to the STA’s construction, procurement and professional services activities.

The STA has established a Disadvantaged Business Enterprise (DBE) Program in accordance with regulations of the U.S. Department of Transportation (USDOT) and their Office of Small and Disadvantaged Business Utilization (OSDBU), Title 49 of the Code of Federal Regulations, Part 26 (49 CFR 26).
