FEMA Flood Zone Lookup

FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). 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 Wilmington, NC.

Zone	What it means	NFIP required?
A	High-risk flood area; 1% annual chance flood, no detailed analysis.	Yes
AE	High-risk; same as A but with established Base Flood Elevations.	Yes
AH	High-risk shallow flooding (1-3 ft), usually ponding.	Yes
AO	High-risk shallow flooding (1-3 ft) with sheet flow on sloping terrain.	Yes
V	High-risk coastal zone subject to wave action (no BFE).	Yes
VE	High-risk coastal zone with wave action and established BFEs.	Yes
X (shaded)	Moderate risk; between the 1% and 0.2% annual chance flood.	Recommended
X	Minimal risk; outside the 0.2% annual chance floodplain.	No

Summary

Wilmington bars anyone from starting development in a special flood hazard area without a floodplain development permit from the floodplain administrator. Sec. 18-661 layers on outright prohibitions inside those zones: no new solid waste, hazardous waste, salvage yard or chemical storage facilities, and no manufactured home outside an existing manufactured home park or subdivision.

(a)Except as provided in subsection 18-661(b), no person may start any floodplain development activities within areas of special flood hazard without having first obtained a floodplain development permit from the floodplain administrator in accordance with this article. ... New solid waste disposal facilities, hazardous waste management facilities, salvage yards, and chemical storage facilities are prohibited in areas of special flood hazard except by variance as authorized under G.S. 143-215.54A(b). ... No manufactured home shall be placed in any area of special flood hazard unless the manufactured home will be located in an existing manufactured home park or existing manufactured home subdivision.

Full Breakdown

Sec. 18-646(a) sets the baseline rule for every parcel inside an area of special flood hazard: before any floodplain development activity begins, the property owner must obtain a floodplain development permit from the city's floodplain administrator, the official who reviews plans against Article 13 of the Land Development Code. The application must show the flood zone designation, the boundary of the special flood hazard area from the FIRM, the floodway or non-encroachment area boundary, the base flood elevation, and the proposed elevation of the lowest floor, all certified by a registered surveyor or engineer under Sec.

18-646(b). Beyond the permit requirement, Sec. 54A(b). Manufactured homes face a parallel restriction, they may only go into an existing manufactured home park or subdivision, and a replacement unit must still meet the anchoring standards of Sec. 18-659(a)(6) and the elevation standards of Sec. 18-660. Floodways and non-encroachment areas carry an even tighter rule under Sec. 18-662: no fill, new construction or other encroachment is allowed there unless an engineer certifies, with hydrologic and hydraulic analysis, that the project will not raise flood levels during the base flood, or FEMA has approved a conditional letter of map revision. The floodplain administrator reviews every application against these standards before clearing a building permit.

Violations & Fines

Development started without a floodplain permit, or a use prohibited under Sec. 18-661 such as a new hazardous waste facility or an unauthorized manufactured home placement, is a code violation the floodplain administrator enforces with a stop-work order under Sec. 18-648(b); disobeying that order is itself a misdemeanor. Any violation of the floodplain article is a Class 1 misdemeanor under G.S. § 143-215.58, carrying up to $100 per day and up to 30 days in jail, with each day counted separately.

Frequently Asked Questions

Do I need a permit to build in a Wilmington flood zone?

Yes. Sec. 18-646(a) requires a floodplain development permit from the city's floodplain administrator before any development activity starts in an area of special flood hazard, including grading, filling and new construction, not just building construction.

What land uses are banned outright in Wilmington's flood hazard areas?

Sec. 18-661(a) prohibits new solid waste disposal facilities, hazardous waste management facilities, salvage yards and chemical storage facilities inside a special flood hazard area, except by variance under G.S. § 143-215.54A(b). Manufactured homes are also barred unless placed in an existing manufactured home park or subdivision.

Can I fill or build in a designated floodway?

Only in narrow circumstances. Sec. 18-662 bars encroachment, including fill and new construction, in a floodway or non-encroachment area unless a registered engineer certifies through hydrologic and hydraulic analysis that the project will not raise base flood levels, or FEMA issues a conditional letter of map revision.
