2023 Regional Flood Plans
The 2023 Regional Flood Plans posted below have been adopted by the regional flood planning groups and approved by the TWDB Board in July 2023. During the first cycle (2020-2023), additional funding was allocated to the Regional Flood Planning Groups in late 2022, enabling them to perform additional outreach, complete select flood mitigation evaluations, and recommend additional flood mitigation projects, and flood mitigation strategies in the plans. The Amended Regional Flood Plans have been approved by the regional flood planning groups and approved by the TWDB on March 5, 2024. The Final Plans will supersede the plans posted below and are now available HERE.
