TCA was formed to improve mobility. We accomplish this by working with partner agencies to prioritize projects that enhance quality of life for Orange County residents. TCA is able to facilitate such projects without placing a financial burden on taxpayers.

Our two Boards of Directors consist of elected officials from each of our 17 member cities and the County of Orange. The Boards meet jointly, though some decisions are considered only by the Agency that a particular action will impact. A small joint staff facilitates Board priorities.
