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 Kent County, DE.

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

Kent County bars any construction, grading, filling, subdivision, manufactured home placement, or storage tank installation within a FEMA-mapped special flood hazard area until the developer obtains a floodplain development permit from the County Floodplain Administrator. Chapter 188, adopted in 2014, implements the National Flood Insurance Program the County joined on March 15, 1978, and covers Zones A, AE, AO and VE in unincorporated Kent County.

These county ordinances apply to unincorporated areas of Kent County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

C. Permits required. It shall be unlawful for any person or entity to begin construction or other development which is wholly within, partially within, or in contact with any identified special flood hazard area, as established in § 188-1D, including but not limited to: subdivision of land, filling, grading, or other site improvements and utility installations; construction, alteration, remodeling, improvement, replacement, reconstruction, repair, relocation, or expansion of any building or structure; placement or replacement of a manufactured home; recreational vehicles; installation or replacement of storage tanks; or alteration of any watercourse, until a permit is obtained from Kent County. No such permit shall be issued until the requirements of these regulations have been met.

Full Breakdown

The Floodplain Administrator, a role assigned to the Director of Planning Services, reviews every application before ground is broken. Under § 188-3D, applicants must submit scaled site plans, an elevation certificate showing existing and proposed grades referenced to the Flood Insurance Rate Map datum, delineation of the special flood hazard area and floodway boundaries, and the elevation of the lowest floor or lowest horizontal structural member. Subdivision or land-development proposals covering at least 50 lots or five acres, whichever is smaller, in areas where FEMA has not published a base flood elevation must also submit a hydrologic and hydraulic engineering analysis under § 188-4B(4).

The Administrator can require the same kind of study for any site lacking mapped base flood elevations, and all such analyses must go to FEMA for approval before recordation. The chapter, Ord. No. 14-03, took effect July 7, 2014, and rests on the FEMA Flood Insurance Study and Flood Insurance Rate Map for Kent County dated the same day, both kept on file at the Department of Planning Services. Historic structures individually listed or eligible for the National Register can seek relief only through a § 188-8 variance, and only when full compliance would destroy the structure's historic designation.

These permit and application duties apply on top of, not instead of, the County's separate zoning (Chapter 205), subdivision (Chapter 187), building (Chapter 105) and drainage (Chapter 116) requirements.

Violations & Fines

Building or developing in a special flood hazard area without the required permit, or contrary to plans the Administrator approved, is prosecuted as a misdemeanor or civil offense under § 188-9C. Convicted violators face a fine of not less than $100 nor more than $1,000, or up to 10 days' imprisonment, or both; the $100 minimum is mandatory and cannot be suspended or reduced, and every day the violation continues counts as a separate offense. County code officials or counsel may also sue to enjoin or abate the unlawful construction.

Frequently Asked Questions

Do I need a permit to build in a Kent County flood zone?

Yes. Under § 188-3C of Chapter 188, it is unlawful to begin any construction, grading, filling, subdivision, or manufactured home placement in a special flood hazard area without first obtaining a floodplain development permit from the County Floodplain Administrator. The permit cannot issue until your application meets every requirement of the chapter, including an elevation certificate and site plan.

What must I submit with a Kent County floodplain permit application?

Section 188-3D requires scaled site plans, the ground elevation referenced to the Flood Insurance Rate Map datum, an elevation certificate, delineation of the special flood hazard area and floodway, and the elevation of the proposed lowest floor. Large subdivisions of 50 or more lots or five or more acres without published base flood elevations must add an engineering study.

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

You risk prosecution under § 188-9C as a misdemeanor or civil offense carrying a mandatory minimum $100 fine, up to $1,000, or up to 10 days in jail, with each day of continued violation charged separately. The County can also sue to enjoin, abate, or remove the unlawful construction.

Can a historic building in the floodplain skip these requirements?

Only through a variance. Section 188-8 lets Kent County waive strict compliance for structures individually listed or eligible for the National Register of Historic Places, but only when full compliance would cause the structure to lose its historic designation and the variance is the minimum necessary to preserve its character.
