Floodplain Regulations

  1. New Construction
  2. Substantial Improvement or Damage
  3. Regulatory Floodway

New construction located on a property in a special flood hazard area (SFHA) shall have the lowest floor or the lowest horizontal structural member of the lowest floor elevated to one foot above the base flood elevation (BFE) of the current Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) in effect at the time of application submittal.

 

Base flood elevations shown on the FIRM are rounded to the nearest foot. Therefore, to ensure the regulatory elevation will be high enough, BFEs are determined by:

In Riverine Areas:            

The BFEs will be determined by using the FIRM and the profiles within the FIS.

In Coastal Areas:             

The BFEs will be determined by using the FIRM then adding .4 feet per recommendations in FEMA 480.

In Coastal Areas east of the Coastal Construction Control Line (CCCL):     

The bottom of the lowest horizontal structural member of the lowest floor shall either be elevated to the elevations specified by the City of Fort Pierce (as mentioned in the above section) or to the 100 year storm elevation determined by the Florida Department of Environmental Protection (DEP), whichever is more restrictive.
