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 Fort Wayne, IN.

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

(B) There shall be no subdivision of land within the defined floodway fringe unless the following conditions are met: (1) It is determined by the city after receipt of additional hydrological or grade studies from the subdivider or appropriate federal or state agencies that the lands to be developed are no longer subject to being covered by flood water of a 100-year frequency flood...

Full Breakdown

Under the subdivision code, no land within the defined floodway may be subdivided at all. In the floodway fringe, a subdivider must submit hydrological and grade studies to the city, get utility extensions and flood-proofing approved in advance, document the 100-year floodplain limits and fill volumes on the primary plat, and show that raising ground elevation won't restrict flood flow onto other land before the Plan Commission will approve the plat.

Violations & Fines

A plat that doesn't meet these floodway/floodway-fringe conditions is not approved by the Plan Commission; subdividers must also arrange for silt regrading after any flooding on land where fill was removed.
