In addition to providing regional mobility solutions that reduce congestion, TCA maintains a strong environmental commitment, having conserved and restored more than 2,100 acres of open space and wildlife habitat across 17 mitigation sites in Orange County. Funded by toll revenues, TCA has invested over $100 million in environmental initiatives that protect ecosystems and support long‑term habitat preservation.
