Regional Flood Plan Development

Trinity Basin

Trinity RFPG Website

In 2019, the Texas Legislature passed Senate Bill 8 that directed the creation of the first-ever State Flood Plan for Texas. The State Flood Plan brings together the findings of the 15 river-basin-based regional flood plans and makes legislative and floodplain recommendations to guide state, regional, and local flood control policy. The Texas Water Development Board (TWDB) adopted Texas’ inaugural 2024 State Flood Plan on August 15, 2024. The Regional Flood Planning Groups (RFPGs) are now responsible for developing Second Planning Cycle Regional Flood Plans (2028). The overall goal of the RFPGs is to determine the nature of flood risk in the regions, evaluate flood mitigation and management practices, and identify projects that reduce flood risk without negatively affecting neighboring areas.

Who can help? The RFPG is seeking participation from everyone affected by flooding. Using the boxes below, please select which type of stakeholder you represent. If you have any trouble, technical issues or wish to coordinate directly with us, please email us.

When is it due? The RFPG will close data collection in Spring of 2025, to allow sufficient time for compilation and assessment in the development of the regional plan.

Please be advised that all information submitted through this survey and interactive map is subject to public review per Texas Water Development Board requirements.
