FEMA flood zone rules in Mount Vernon, NY — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Mount Vernon is largely inland but has FEMA Zone AE along the Hutchinson River and Bronx River corridors. City participates in NFIP; flood insurance mandatory for federally-backed mortgages in SFHAs.
Mount Vernon sits above tidewater but the Hutchinson River and Bronx River produce AE flood zones along their banks. FEMA FIRMs for Westchester County (panel 36119C) identify SFHAs. Mount Vernon Code Chapter 150 (Flood Damage Prevention) governs construction in special flood hazard areas — elevation certificates, freeboard requirements, and a development permit from the Building Department are required.
Building in SFHA without a floodplain development permit: stop-work order, fines, and required elevation/removal. Non-elevated substantial improvements jeopardize NFIP eligibility.
