Grand Isle

FEMA flood zone (parcel): X

Coastal Barrier Resources System (CBRS): Outside all three

Coastal Construction Control Line (CCCL): Landward

Evacuation zone: B

Critically eroded shoreline: Critical. Florida DEP designates the Seagrove Beach shoreline (R78 to R98) as critically eroded — the state's term for a beach where erosion now threatens buildings, roads, parks or habitat. A restored beach keeps that designation so it stays eligible for state money to maintain it. WaterColor and Seaside sit landward of the control line and were added to this segment so the federal project could be managed as one stretch. The nearest point of that stretch sits about 1,400 feet from this building.
