Relating to the creation of certain regional conservation and reclamation districts.

HB 3363 creates new regional conservation and reclamation districts in specific Texas counties meeting population thresholds (e.g., counties with 3.3 million+ residents or bordering such counties, or border counties with over 400,000 residents and two cities of 70,000+ each). It establishes a petition process for creating these districts, requiring either: (1) 20% of municipal districts in the area, (2) landowners with 2,000+ contiguous acres, or (3) county commissioners courts or municipal governments to submit formal requests to the Texas Commission on Environmental Quality. The bill amends the Water Code to define these districts, clarify the Commission’s role, and set eligibility criteria for district creation. It directly affects local governments, landowners, and water management in designated counties.
