The bill significantly restructures the governance of the Harris County Flood Control District by establishing a new governing body known as the "Board," which replaces the previous role of the Commissioners Court. It introduces definitions for key terms and outlines the process for expanding the district to include adjacent counties through voter elections. The Board is granted expanded powers, including the ability to acquire and manage property for flood control, hire personnel, and collaborate with federal and local entities. The bill emphasizes the importance of effective flood control and stormwater management, aiming to enhance the district's operational capabilities.

Additionally, the bill modifies existing laws regarding bond issuance for flood control projects, clarifying that the Board is responsible for these decisions instead of the Commissioners Court. It establishes procedures for bond issuance, including the requirement for Attorney General approval and registration with the Comptroller of Public Accounts, while also setting a limit on initial bond issuance tax rates. The Board is empowered with eminent domain for property acquisition and must adhere to state laws regarding public funds. The bill also includes provisions for maintaining transparency in financial management and outlines the appointment process for Board members, ensuring effective leadership and continuity within the district.
