Zone A, AE and X in plain English
On the FIRM covering Morgan County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. A surveyor working near Wartburg uses the base flood elevation printed for AE zones; unnumbered A zones do not have one. Shaded Zone X around Wartburg sits in the moderate band between the 100-year and 500-year floods. Unshaded Zone X near Oakdale is minimal risk.
Creeks, rivers and low ground in Morgan County
In Morgan County, look closest at tracts along Emory River, New River and Big South Fork of the Cumberland River. Lines on those Morgan County parcels frequently follow the water, so part of the tract can be mapped as high risk. A low spot on a Morgan County tract outside any mapped zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
Questions to ask before buying in Morgan County
For a house near Oliver Springs, ask the seller for any elevation certificate on file and the current flood insurance declarations page. Quotes for land near Deer Lodge depend on the zone and the building's elevation, so bring both to the agent.
What a flood zone means for a Morgan County buyer
The zone displays up again when a loan on a house near Oakdale is underwritten. If a barn or house outside Wartburg is mapped in a high-risk zone and is financed by a regulated or federally insured lender, flood insurance is mandatory; that applies where the local government around Oakdale is in the National Flood Insurance Program. Outside the A zones around Oakdale, federal rules do not require a policy, though a lender in Tennessee can still ask for it. Where a structure near Wartburg looks higher than the shading suggests, FEMA's LOMA process allows a review; a surveyor near Oakdale can supply the elevation data. Building or filling inside a mapped zone near Wartburg frequently requires a permit and an elevation check, so call the county or the town office in Wartburg before work starts.
