FEMA flood zone rules in Long Beach, MS — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Long Beach is a Mississippi Gulf Coast NFIP community with extensive coastal flood exposure. Eight property-damaging floods have occurred in the last 20 years, including Hurricanes Georges (1998) and Katrina (2005). The current flood-control instrument is Flood Plain Ordinance #652 (effective Sept 7, 2020), which superseded Floodplain Management Ordinance #642 (2019) and earlier #565/#610. FEMA FIRM panels show V/VE zones along the Gulf and AE zones inland; elevation certificates are required for new construction since October 2005. Substantial improvement (>50% of pre-improvement value) triggers full elevation compliance.
Long Beach participates in the National Flood Insurance Program and enforces FEMA-compliant construction standards through Flood Plain Ordinance #652 (2020). The Building Permit Office issues FIRM zone determinations and base flood elevations and maintains elevation certificates for all construction since Oct 2005. Coastal V/VE zones (high wave hazard) require pile/column foundations and Coastal A construction; AE zones require lowest-floor elevation to BFE. Substantial improvement and substantial damage rules under 44 CFR §59.1 trigger full code compliance. Mississippi guidance (MEMA Quick Guide) recommends 18 inches of freeboard. Stormwater is controlled by Erosion & Sediment Ordinance #602 and Illicit Discharge Ordinance #603. Flood insurance is mandatory in any A or V zone with a federally-backed mortgage.
Building below BFE or without an elevation certificate triggers stop-work orders, denial of certificate of occupancy, and potential NFIP probation that raises every property owner's insurance rates. Substantial-improvement violations require retroactive elevation.
