Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Cary, NC.

Full Breakdown

Under the Land Development Ordinance, no development may occur in a mapped flood hazard area until the Floodplain Administrator confirms it meets the flood damage prevention standards of LDO § 14.7. Applicants file with the Floodplain Administrator, who reviews and issues the permit only if the proposal conforms to those standards. Non-residential structures in the flood hazard area additionally need a Zoning Board of Adjustment special use permit. This applies inside Cary's Wake County town limits and its extraterritorial jurisdiction, not merely to a Cary mailing address.

Violations & Fines

No permit, certificate, or approval may issue for development that does not meet the flood damage prevention standards; the Floodplain Administrator's decisions are appealable to the Zoning Board of Adjustment.
