The bill amends the existing law regarding local government authority to regulate land use in flood-prone areas. It grants cities, towns, and counties the power to enact ordinances and codes for managing land and structures in these areas, while also allowing them to implement measures aimed at reducing flood damage and guiding development away from flood hazards. However, the bill introduces a significant restriction: local governments are prohibited from enacting regulations that are more stringent than the requirements set forth by the National Flood Insurance Program without providing compensation for any decrease in property value resulting from such regulations.

Specifically, the new language stipulates that local governments cannot adopt regulations in areas designated as special flood hazard zones that exceed the guidelines established by the National Flood Insurance Program as of January 1, 2025. This provision aims to ensure that local regulations do not impose undue burdens on property owners in flood-prone areas while still allowing for necessary flood management measures.
