High, moderate and minimal risk in Meigs County
On the FIRM covering Meigs County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Where a Meigs County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there is not one. If a Meigs County parcel displays shaded Zone X, it is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded X (or C) on the Meigs County panel means minimal risk.

Decatur is the seat of Meigs County and the hub for its land records.

Waterfront and bottomland parcels near Big Spring often carry a zone along one edge, so check where the buildable part sits.

Flood insurance and building rules in Meigs County
The zone displays up again when a loan on a house near Decatur is underwritten. Where a building in Big Spring sits in a Special Flood Hazard Area and is financed by a regulated or federally insured lender, a flood policy becomes a loan condition, as long as Meigs County or the town participates in the NFIP. In Zone X near Big Spring, coverage is optional, though a lender in Tennessee can still ask for it. Where a structure near Big Spring looks higher than the shading suggests, the owner can ask FEMA for a Letter of Map Amendment (LOMA), supported by elevation data from a professional surveyor. Placing fill on low ground near Big Spring often requires a permit and an elevation check, and the building office serving Decatur explains the steps.
