H.B. No. 1535 amends the governing structure and operational guidelines of the Trinity River Authority of Texas, following recommendations from the Sunset Advisory Commission. Key changes include extending the review period of the Authority under the Texas Sunset Act to September 1, 2037, and increasing the number of directors on the Board from twenty-four to twenty-five. The bill also modifies the terms of directors from six years to four years, with specific provisions for staggered terms. Additionally, it establishes new grounds for the removal of board members, including failure to maintain qualifications, violation of local government laws, and excessive absences from meetings.

The bill introduces a mandatory training program for newly appointed directors, which must be completed before they can vote or participate in board meetings. It also mandates the creation of a complaint management system and policies to ensure public participation in board meetings. The changes aim to enhance accountability, governance, and transparency within the Authority. The act is set to take effect on September 1, 2025.
