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 Greeley, CO.

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

Full Breakdown

Development Code § 24-1001(c) requires a floodplain development permit before any "construction or development" inside the floodplain overlay district, which covers all FEMA-mapped special flood hazard areas plus land removed from the floodplain by a FEMA letter of map revision. City Code § 12-1206(a) sets the same requirement citywide and lists ten factors the floodplain administrator weighs, flood and erosion danger, drainage impact, emergency-vehicle access and compatibility with the comprehensive plan, before approving or denying an application. Variances from the floodplain rules go to the zoning board of appeals under a stricter hardship standard than the ordinary development-code variance process.

Violations & Fines

Building or grading in the floodplain overlay district without a permit is a Code violation; the city can withhold approval, and unpermitted work loses the "prior approved activities" protection given to properly permitted construction.
