Relating to the review and updating by the Texas Water Development Board of guidance principles and rules related to certain plans adopted or approved by the board.

HB 3628 requires the Texas Water Development Board to review and update its guidance principles and rules for the state water plan and state flood plan at least every five years, aligning with the existing five-year cycle for adopting new plans. The bill exempts these specific water and flood plan rules from the standard Government Code requirement that most rules be reviewed every four years. This applies to guidance principles adopted under Sections 16.051 and 16.061 of the Water Code, involving coordination with agencies like the Texas Commission on Environmental Quality, Agriculture Department, and Parks and Wildlife Department. The bill directly affects the Board’s planning processes and its collaboration with state agencies on water resource management.
