Relating to the authority of the Harris-Galveston Subsidence District over the North Harris County Regional Water Authority.

HB 1643 exempts the North Harris County Regional Water Authority from the regulatory authority of the Harris-Galveston Subsidence District. Specifically, it removes the applicability of Chapter 8801 (governing district territory) and certain groundwater management laws (including those requiring groundwater reduction plans) to the water authority and its service area. This change directly affects the water authority's operational independence and its relationship with the subsidence district, particularly regarding groundwater usage regulations. The bill creates a clear jurisdictional separation between the water authority and the subsidence district's oversight.
