FL H0111

Expands the Resilient Florida Grant Program to allow the Department of Environmental Protection (DEP) to provide grants to water management districts for local government adaptation planning, data collection, and modeling, with priority given to filling critical data gaps identified by the Florida Flood Hub for Applied Research and Innovation.

Creates s. 380.0937, F.S., requiring state-financed constructors to complete a Sea Level Impact Projection (SLIP) study before commencing construction of potentially at-risk structures or infrastructure in areas projected to be below the tidal flooding threshold (2 feet above mean higher high water) within 50 years, effective July 1, 2024.

SLIP studies must assess flooding, inundation, and wave action risks over the structure's expected life or 50 years (whichever is less), provide design and siting alternatives, evaluate flood mitigation strategies, and analyze public safety and environmental impacts; the DEP must develop study standards by rule and may require professional engineer sign-off.

Authorizes DEP to bring civil actions seeking injunctive relief to halt non-compliant construction or to recover state funds expended on completed projects that did not comply with the SLIP study requirement, though the law does not create a private cause of action for damages based on failure to implement study findings.

Repeals s. 161.551, F.S. (public financing requirements for construction in the coastal building zone) on July 1, 2024, effectively replacing it with the new SLIP study framework; the act takes effect July 1, 2023.
