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.

Your specific zone determines insurance cost, build elevation, and permit requirements in Iredell County, NC.

Full Breakdown

Appendix G, the county's Flood Damage Prevention Ordinance (adopted September 18, 2018, amended April 20, 2021), applies to all Special Flood Hazard Areas mapped in the FEMA Flood Insurance Study dated November 16, 2018 (Article 3, Sections A-B). Article 3, Section C requires a Floodplain Development Permit before any development activity in these zones, and Section D bars locating, extending, converting, altering, or developing structures or land without full compliance. The Planning Director, designated as Floodplain Administrator under Article 4, Section A, reviews applications. Article 4, Section B spells out the application package: a scaled plot plan showing the SFHA boundary, flood zone designation, floodway or non-encroachment boundaries, and Base Flood Elevation where established, certified by a registered land surveyor or professional engineer (accessory projects under 150 square feet or $3,000 outside a floodway are exempt from certification).

Applicants must also submit proposed elevations referenced to NAVD 1988 for the structure's reference level, and, where floodproofing is used, a FEMA Floodproofing Certificate (Form 086-0-34) with an operational and maintenance plan. The Regulatory Flood Protection Elevation is defined as the Base Flood Elevation plus two feet of freeboard, or two feet above the highest adjacent grade where no BFE has been set. Article 4, Section C lists 22 duties of the Floodplain Administrator, including issuing stop-work orders, revoking permits for false statements or substantial departure from approved plans, and notifying FEMA and the state before any watercourse alteration or relocation.

Variance requests go to the Board of Adjustment under Article 4, Section E, which must weigh danger to life and property, availability of alternative sites, and the cost of governmental services during flood conditions before granting relief; variances below the BFE trigger a mandatory written warning that flood insurance premiums can run up to $25 per $100 of coverage.

Violations & Fines

Article 3, Section H makes any violation, including breach of a variance condition, a Class 1 misdemeanor under N.C.G.S. § 143-215.58, punishable by a fine of not more than $100.00 or imprisonment up to 30 days, or both, with each day of continued violation a separate offense. Article 4, Section D's corrective procedure requires the Floodplain Administrator to notify the owner, hold a hearing within 10 days if the violation is not fixed, and, if still unresolved, order a remedy within 60 to 180 days; ignoring a final corrective order after appeal is also a Class 1 misdemeanor. The Administrator can revoke a permit outright for false statements or refusal to comply with state or local law.

Frequently Asked Questions

Who issues floodplain development permits in Iredell County?

The Floodplain Administrator, a role filled by the Planning Director or a designee under Article 4, Section A of the Flood Damage Prevention Ordinance. The Administrator reviews plot plans, elevation data, and floodproofing certificates before issuing or revoking a permit.

What happens if I build in the floodplain without a permit?

It is a Class 1 misdemeanor under N.C.G.S. § 143-215.58, punishable by up to a $100 fine or 30 days in jail, with each day the violation continues counted as a separate offense. The county can also pursue other lawful remedies to stop or correct the work.

Is every small structure required to have an elevation certificate?

No. Accessory structures of 150 square feet or less, or valued at $3,000 or less, that sit outside a floodway or non-encroachment area are exempt from the certification requirements in Article 4, Section B(3).

Can I get a variance to build below the Base Flood Elevation?

The Board of Adjustment can grant one only on a showing of good cause and exceptional hardship, and never within a floodway if it would raise flood levels. Anyone granted a variance must receive written notice that building below the BFE can raise flood insurance premiums as much as $25 per $100 of coverage.
