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 Hall County, GA.

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

Summary

No owner or developer may start any development activity in a Hall County area of special flood hazard or future-conditions flood hazard without first meeting the county's flood protection permit requirements. Sec. 10.2.3.A requires a Hall County Development Services permit application before any grading, filling, or construction begins on a mapped flood-hazard parcel.

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

No owner or developer shall perform any development activities on a site where an area of special flood hazard or area of future-conditions flood hazard is located without first meeting the requirements of this section prior to commencing the proposed activity.

Full Breakdown

Sec. 1 of the Hall County Flood Protection ordinance applies to every area of special flood hazard and area of future-conditions flood hazard identified on the county's Flood Insurance Study, and Sec. A carries the operative prohibition: no owner or developer may perform development activities on such a site without first meeting the section's requirements. The permit application, filed with Hall County Development Services on the county's form, must include a scaled site plan showing existing and proposed elevations, the footprint of every proposed structure with spot ground elevations at the corners, proposed water, sewer, and drainage locations, a grading plan, the base flood and future-conditions flood elevations, the boundaries of both floodplains, and, where one exists, the location of the floodway, all certified by a licensed engineer or surveyor.

The application must also include building and foundation design detail, including the elevation in relation to mean sea level of the lowest floor of every proposed structure. No permit may be approved for a project that does not meet the section's requirements, restrictions, and criteria. Sec. 4 defines the floodplain and floodway boundaries the permit review works from, using FEMA's studied 'A' zones for the base flood elevation and directing the Hall County Engineer, or a licensed engineer using a FEMA-approved method, to set the future-conditions flood elevation for any stream draining 100 acres or more when FEMA data isn't available.

A property owner who disagrees with a floodplain determination or a permit condition can request a variance from the Hall County Engineer under Sec. 6, with a further appeal to the Planning Commission within 30 days of the Engineer's decision.

Violations & Fines

Sec. 10.2.7 treats development in a flood hazard area without the Sec. 10.2.3 permit as a code violation: the county serves a written notice of violation directly on the property owner or the person running the site, and a continuing violation is deemed a public nuisance the county can abate through injunctive or other equitable relief, on top of any other penalty available under the Code.

Frequently Asked Questions

Do I need a permit to develop in a Hall County flood zone?

Yes. Sec. 10.2.3.A bars any owner or developer from starting development activity on a site within a mapped area of special flood hazard or future-conditions flood hazard until Hall County Development Services approves a permit application meeting the section's site plan and design requirements.

What has to be on a Hall County floodplain permit application?

Sec. 10.2.3 requires a scaled site plan showing the base flood and future-conditions flood elevations, the floodplain and floodway boundaries, spot ground elevations at every proposed structure's corners, and proposed drainage and utility locations, all certified by a licensed engineer or surveyor before the county will approve the permit.

Who sets the flood elevation data Hall County uses for permitting?

For streams with at least 100 acres of drainage area, Sec. 10.2.4.A directs the Hall County Engineer to provide the future-conditions flood elevation; if that data isn't available, a licensed professional engineer must determine it using a method approved by both FEMA and the Hall County Engineer.

Can a property get a variance from the floodplain permit rules?

Yes. Sec. 10.2.6 lets an owner request a variance from the Hall County Engineer, who must give affected parties notice and a chance to be heard, and a decision can be appealed to the Hall County Planning Commission within 30 days.
