The bill revises the governance and territorial structure of the Harris County Flood Control District, establishing it as a governmental agency with jurisdiction that now aligns with Harris County. It introduces new sections that define key terms, outline the process for incorporating adjacent counties, and establish a five-member board appointed by the governor to oversee district operations. The board is granted expanded powers, including property acquisition, personnel hiring, and the ability to enter cooperative agreements with other governmental entities. Additionally, the bill details the procedures for issuing bonds for flood control projects, emphasizing public notice and transparency in decision-making.

Key changes include replacing references to the "Commissioners Court" with "Board," reflecting a shift in governance. The bill allows the District to issue bonds with a maturity of up to thirty years and mandates the adoption of building setback lines for public health and safety. It also expands the District's capacity to engage in recreational and environmental projects, ensuring these do not interfere with flood control efforts. The bill repeals outdated provisions and establishes a clear process for appointing board members, ultimately aiming to enhance the District's operational capabilities while prioritizing flood control and public welfare.
