   21          
   22  Be It Enacted by the Legislature of the State of Florida:
   23  
   24         Section 1. 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         553.845Flood 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.
