This act may be cited as the “Flood Damage 25 Prevention Act of 2024.” 26 Section 2. Section 553.845, Florida Statutes, is created to 27 read: 28 553.845 Flood damage prevention.— 29 (1) The Legislature finds that: 30 (a) The state is vulnerable to the adverse effects of 31 flooding resulting from the frequency and intensity of rainfall 32 and an increase in storm surge and sea level rise. These adverse 33 effects pose a significant risk to existing and future 34 structures in the state. 35 (b) Public and private investments in our communities are 36 important for economic growth, and protecting all structures 37 from flooding is essential to maintaining resilient communities. 38 (c) The mitigation of property damage constitutes a valid 39 and recognized objective of the Florida Building Code. 40 (d) It is important to develop a consistent, statewide 41 approach to minimizing flooding in the state to mitigate 42 property damage and encourage continued investment in our 43 communities. 44 (e) Minimum freeboard requirements are critical to 45 addressing the devastating effects of flooding, and delaying the 46 adoption and implementation of such requirements constitutes a 47 threat to the health, safety, and welfare of the state. 48 (2) For purposes of this section, the term: 49 (a) “Coastal high-hazard area” means a special flood hazard 50 area along the coast, as delineated by a Flood Insurance Rate 51 Map issued by the Federal Emergency Management Agency, which has 52 additional hazards due to wind and wave action. 53 (b) “Freeboard” means the additional height, usually 54 expressed as a factor of safety in feet, above the base flood 55 elevation in determining the level at which a structure’s lowest 56 floor or the bottom of the lowest horizontal structural member 57 must be elevated in accordance with floodplain management 58 regulations and the Florida Building Code. If a base flood 59 elevation is not determined for a structure that is not located 60 in a special flood hazard area as designated by a Flood 61 Insurance Rate Map issued by the Federal Emergency Management 62 Agency, the term “freeboard” means the highest adjacent grade at 63 the foundation of a structure. 64 (c) “Maximum allowable height” means the maximum height 65 allowed for a structure in the applicable zoning district. 66 (d) “Substantial improvement” has the meaning as in s. 67 161.54(12). 68 (e) “Voluntary freeboard” means the additional height above 69 the freeboard required by floodplain management regulations and 70 the Florida Building Code. If freeboard is not required by 71 floodplain management regulations and the Florida Building Code, 72 the term “voluntary freeboard” means the additional height above 73 the highest adjacent grade at the foundation of a structure. 74 (3) The maximum voluntary freeboard for all new 75 construction and substantial improvements to existing 76 construction, whether residential, commercial, industrial, or 77 nonresidential, is 10 feet, including within a coastal high 78 hazard area. 79 (4) For all new construction or substantial improvements to 80 an existing commercial, industrial, nonresidential, or 81 residential structure, including a manufactured home, voluntary 82 freeboard may not be used in the calculation of the maximum 83 allowable height for the structure. 84 (5) A local government may adopt by ordinance a minimum 85 voluntary freeboard requirement or a maximum voluntary freeboard 86 that exceeds the requirements in the Florida Building Code or 87 those established in this section. 88 (6) The commission shall develop and adopt by rule minimum 89 voluntary freeboard requirements by November 1, 2024, which 90 shall take immediate effect, and shall incorporate such 91 requirements into the next edition of the Florida Building Code. 92 (7) Beginning in January 2029, and every 5 years 93 thereafter, the commission shall review the freeboard 94 requirements in the Florida Building Code and make 95 recommendations to the Legislature regarding any necessary 96 revisions to such requirements. 97 Section 3. This act shall take effect July 1, 2024.
