Coral Gables, FL Environmental Rules: Coastal Development (2026)

Coral Gables contains areas subject to coastal flood hazards, particularly near Biscayne Bay, the Coral Gables Waterway, and numerous canals throughout the city. Properties in FEMA-designated flood zones must comply with base flood elevation (BFE) requirements, and Flood Elevation Certificates are required for all new construction and substantial improvements. The entire city is within the Miami-Dade High-Velocity Hurricane Zone (HVHZ), requiring enhanced structural standards for wind resistance under the Florida Building Code. The Coastal Construction Control Line (CCCL) established by the Florida DEP restricts construction seaward of the line and requires special permitting. Substantial improvements—defined as repairs or improvements costing 50% or more of the building's market value—must bring the entire structure into compliance with current flood zone requirements. New construction in flood zones must be elevated to or above the BFE plus any local freeboard requirements. Flood-resistant materials must be used for all construction below the BFE. The city participates in the National Flood Insurance Program (NFIP) and the Community Rating System (CRS), which may provide flood insurance premium discounts to residents. Seawalls along waterways must be maintained to the standards established by the city. Miami-Dade County DERM reviews projects that may affect coastal resources.
