Full Breakdown
FEMA FIRM maps (effective October 5, 2017) classify PBC properties into Special Flood Hazard Areas (SFHAs).

AE zones (1 percent annual chance flood) require lowest finished floor at or above BFE plus 1-foot freeboard per PBC ordinance. X zones (minimal hazard) carry no federal flood insurance mandate. Substantial improvement (50 percent of structure value) triggers full flood compliance for older non-conforming homes. PBC participates in FEMA Community Rating System (CRS Class 5) providing 25 percent NFIP premium discount.
