High, moderate and minimal risk in Decatur County
Any Decatur County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, defined by a 1-percent annual chance of being flooded. Zone AE near Scotts Hill means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Shaded Zone X around Decaturville is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Scotts Hill is minimal risk.
Low ground and small streams around Decaturville
A creek near Scotts Hill that shows no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.

Flood insurance and building rules in Decatur County
Lenders watch the zone closely on Decatur County properties. If a house near Scotts Hill sits in a Special Flood Hazard Area and secures a loan from a federally regulated or insured lender, a flood policy becomes a loan condition under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a county home in shaded or unshaded X, federal rules don't require a policy; pricing a policy for land near Scotts Hill is still worth a call. If a building near Scotts Hill sits above the flood line, the landowner can ask FEMA for a Letter of Map Amendment (LOMA), generally backed by an elevation certificate from a surveyor who works in the county. Building or filling inside a mapped zone near Decaturville often requires a permit and an elevation check, and the building office serving Scotts Hill explains the steps.
