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 Jacksonville, FL.

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

Full Breakdown

Chapter 652 (Floodplain Management) requires a floodplain development permit before any construction, filling, grading, or utility work in a mapped flood hazard area, layered on top of any Florida Building Code permit. The Floodplain Administrator (Chief of the Development Services Division) reviews applications against the city's Flood Insurance Rate Maps. Sec. 652.1005 sets the elevation bar: new and substantially improved buildings in Special Flood Hazard Areas and Adjusted SFHAs must have their lowest floor at or above base flood elevation plus 2 feet of freeboard, using off-grade or stem-wall construction rather than filling the lot more than 1 foot above base flood elevation.

Violations & Fines

Building without a floodplain permit, in conflict with an issued permit, or without documented lowest-floor elevation is a violation under Sec. 652.801; the Floodplain Administrator can issue a stop-work order or notice of violation, and continuing work after that is subject to further penalties.

Frequently Asked Questions

Do I need a permit to fill or grade land in a Jacksonville flood zone?

Yes. Sec. 652.401 requires a floodplain development permit for filling, grading, and site work in any flood hazard area, separate from a building permit.

How high above base flood elevation must a new house be built?

Sec. 652.1005 requires the lowest floor at least 2 feet above base flood elevation, or the design flood elevation if higher.
