HJR 129 proposes a constitutional amendment requiring that the board members of the Texas Water Development Board be elected by qualified voters at a general election rather than appointed by the governor. It amends Section 49-c(a) of Article III of the Texas Constitution to reflect this change, allowing the qualifications, compensation, and number of board members to continue being determined by law. The resolution includes a temporary provision that allows current board members to remain in office until their terms expire or they are otherwise removed, with the provision set to expire on January 1, 2030. If approved by the legislature, the proposed amendment will be placed on the ballot for voter approval in the general election on November 4, 2025.
