FEMA flood zone rules in Pasco County, FL — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Pasco County has extensive flood zones along the Gulf Coast, Anclote River, and Pithlachascotee River. During Hurricane Milton (2024), the Anclote River crested at 26.57 feet, causing historic flooding officials called a '200-year flood event.' FEMA zones AE, A, AH, AO, and VE/V designate Special Flood Hazard Areas with mandatory flood insurance.
Pasco County provides a 'Find My Flood Zone' tool on their website. SWFWMD identifies 12+ floodplain areas in Pasco County including Anclote East/West, Cypress Creek, Pithlachascotee River/Bear Creek, and Lower Coastal. New FEMA Flood Insurance Rate Maps are being developed. The county recommends new construction meet Base Flood Elevation from preliminary maps.
Construction below flood elevation: retroactive compliance required, fines $500 to $5,000. Floodway encroachment: removal order. Failure to maintain flood insurance: lender force-placement at higher cost.
