H.B. No. 210 mandates a comprehensive study by the Texas Water Development Board, in collaboration with various state and federal agencies, to assess the costs associated with developing flood infrastructure in Texas. The study will focus on identifying high-cost drainage zones, analyzing factors that drive flood infrastructure costs, and comparing historical project costs across different regions. It will also involve creating a flood infrastructure cost heat map, estimating costs for various flood mitigation strategies, and projecting future costs based on updated precipitation frequency data.

The bill requires the board to submit a written report of its findings and recommendations to the legislature by December 1, 2026, and to make this report publicly accessible on its website. The act is set to expire on April 1, 2027, and will take effect 91 days after the conclusion of the legislative session.
