Relating to the records, management, and taxation of navigation districts and certain port and harbor facilities.

HB 4148 modifies record-keeping, meeting rules, and purchasing authority for Texas navigation districts, port authorities, and certain harbor boards. It allows these entities to adopt electronic record storage standards (including converting hard copies to digital formats), exempts port commissions from recording closed security-related meetings, and increases routine purchasing limits from $100,000 to $500,000 for delegated officials. The bill ensures electronic retention standards comply with existing state/federal retention requirements and excludes these entities from certain governmental entity definitions. It directly affects local port and harbor management bodies by changing their administrative procedures.
