H.B. No. 311 mandates the Texas Water Development Board to conduct a study assessing the need for standards regarding the placement of recreational vehicles and temporary dwelling structures in flood hazard areas. The bill defines "flood hazard area" as land designated by the Federal Emergency Management Agency (FEMA) under the National Flood Insurance Act or identified as flood-prone based on FEMA's engineering models. The board is authorized to consult with FEMA and other relevant agencies to gather necessary information for the study.

The board is required to submit a report by January 1, 2027, detailing the study's findings and legislative recommendations to the governor, lieutenant governor, speaker of the house, and all members of the legislature. The act is set to expire on February 1, 2027, and will take effect 91 days after the conclusion of the legislative session.
