Relating to flood safety and disaster preparedness.

HB 55 requires municipalities and counties to install outdoor warning sirens at two-mile intervals along rivers in areas classified as "flood-risk zones" (defined as locations impacted by flooding at least once in the past 100 years). Each siren must include a water-level sensor and solar-powered backup energy. Local governments are responsible for installation, maintenance, and operation based on whether the area is incorporated (municipality) or unincorporated (county). The bill also mandates regular testing of all sirens to ensure functionality during flood events.
