Relating to the filing with the county clerk of certain counties of a draft of a petition requesting the creation of a municipal utility district.

HB 363 requires petitioners seeking to create a municipal utility district to send certified mail notice to county commissioners courts at least 30 days before filing their petition with the Texas Commission on Environmental Quality. The notice must describe the proposed district's boundaries (using exact location details) and inform counties of their right to respond, review the petition, and submit written opinions. This bill amends the Water Code to add Section 54.0135 (requiring the notice) and updates Section 54.015 (adding a requirement that petitions include a copy of this notice). It applies only to petitions filed on or after the bill's effective date, directly affecting counties and those proposing new utility districts.
