Wake County, NC Environmental Rules: Flood Zones (2026)

Wake County participates in the Federal Emergency Management Agency's National Flood Insurance Program (NFIP) and administers flood hazard regulation through the Watershed Management Division within Planning and Development Services. Per the Division's published mission, staff 'review development projects and issue permits to help prevent flooding, excessive erosion, and water pollution,' and conduct inspections during and after construction to verify proper grading and functioning stormwater systems (wake.gov/departments-government/watershed-management).

The regulatory floodplain in unincorporated Wake County follows FEMA's effective Flood Insurance Rate Maps (FIRMs), and Wake County GIS publishes the flood layers so property owners can determine whether a parcel is in a Special Flood Hazard Area (SFHA) - typically Zone A (no Base Flood Elevation determined) or Zone AE (BFE determined). Local floodplain development standards - including freeboard, fill, and substantial-improvement rules - are codified in the Wake County Unified Development Ordinance (UDO), which Planning and Development Services administers from the Waverly F. Akins Wake County Office Building at 336 Fayetteville St., Raleigh.

For a property in the SFHA, an applicant must coordinate with both Watershed Management (919-856-7436) on the floodplain development review and Permits and Inspections (919-856-6222) on the underlying building permit. Inside incorporated cities and towns (Raleigh, Cary, Apex, Garner, etc.), the municipality's own floodplain ordinance and flood administrator govern instead.
