Coral Gables, FL Environmental Rules: Flood Zones (2026)

Coral Gables is susceptible to flooding due to its proximity to the Atlantic Ocean, Biscayne Bay, and an extensive canal system, combined with near-sea-level elevations and a high water table. FEMA Flood Insurance Rate Maps designate multiple flood zones throughout the city including AE zones (detailed study with BFE) and VE zones (coastal high hazard) along the waterfront. All new construction and substantial improvements within designated flood zones must comply with NFIP requirements. Buildings must be elevated so that the lowest floor is at or above the Base Flood Elevation shown on the FIRM. Flood Elevation Certificates are required for new construction, additions, and substantial improvements to document compliance. The city participates in the Community Rating System, which may qualify residents for reduced flood insurance premiums based on the city's floodplain management practices. Flood-resistant materials must be used for all components below the BFE. Enclosed areas below the BFE must have flood openings (vents) to equalize hydrostatic pressure. Fill used to elevate structures must not displace floodwater or cause adverse flooding impacts on adjacent properties. The city has invested in automated flood gate controls at canal mouths to mitigate urban flooding. Residents can obtain flood zone determinations from the Development Services Department or check Miami-Dade County flood zone maps online.
