Permitting on Key Biscayne

The Village of Key Biscayne Building, Zoning and Planning Department reviews the permit. The Village counts improvements against the home's market value: at 49%, including additions from the year before, the whole house has to be raised to flood elevation or floodproofed, so we size the scope with that line in mind. New homes sit at least 18 inches above the crown of the street or 24 inches above average lot grade. Seawalls, docks and lifts on tidal water also need a Miami-Dade Class I environmental permit (DERM); the sealed plans are what that application attaches. Oceanfront lots seaward of the state Coastal Construction Control Line add a state coastal permit. All of it is High-Velocity Hurricane Zone: Miami-Dade NOAs and HVHZ provisions on the set.
