Fiscal Analysis

The bill would require the Texas Water Development Board (TWDB), in coordination with the Texas Department of Transportation (TxDOT), the Texas Commission on Environmental Quality (TCEQ), the General Land Office (GLO),  the Federal Emergency Management Agency, and regional flood  planning groups, drainage districts, and local governments, to conduct a study and to develop and publish a report by September 1, 2026, regarding the costs of developing flood infrastructure in the state. The bill would require the study to meet prescribed criteria and that the report provides related findings and recommendations.

The bill would take effect on September 1, 2025, and would expire on January 1, 2027.

Methodology

The table above reflect one-time General Revenue Fund costs needed to implement the provisions of the bill based on the analysis and information provided by TWDB. According to TWDB, the cost analysis is based on existing technical consultant contracting used for the regional flood planning process and accounts for the timeline and scope required of the study and report. This analysis assumes all costs would occur in fiscal year 2026 due to the deadline for the report being September 1, 2026.

According to TxDOT, TCEQ, and GLO, it is assumed that any costs associated with the bill to agencies with coordination responsibilities could be absorbed using existing resources.

Local Government Impact

No significant fiscal implication to units of local government is anticipated.
