Relating to the issuance of obligations by certain water districts bordering certain counties during a disaster declaration.

HB 4820 allows specific water districts bordering the Gulf of America and an international border to issue short-term debt (notes) during disaster declarations without the usual three-year term limit. It directly affects districts in counties without cities over 750,000 population and not adjacent to such counties. The bill requires these districts to submit note authorizations to the attorney general for approval and makes issued notes "incontestable" in court during the declared disaster period. This change streamlines emergency funding access for affected water districts while maintaining oversight through attorney general review.
