Greene County at a glance
Greeneville is the county seat, and Tusculum, Baileyton, and Mosheim are among the other towns on the county map. Unincorporated communities in the county, including Fall Branch, Afton, and Camp Creek, display up as small groups of parcels along the roads. Greene County had an estimated 72,577 people in 2023 (Census Bureau), spread across about 622 square miles. The Greene County map mixes subdivision lots near Greeneville with farm and wooded tracts farther out. Landforms such as the Ridge-and-Valley Appalachians and Blue Ridge Mountains shape where roads and homesites fall in Greene County. Greene County was organized in 1783, so deeds for older farms near Mosheim can run back a long way.
What the flood zone letters mean
On the FIRM covering Greene County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Zone AE near Greeneville means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a Greene County parcel displays shaded Zone X, it falls between the base flood and the 500-year flood. Unshaded Zone X near Greeneville is minimal risk.
Where water shapes land in Greene County
Parcels touching Davy Crockett Lake deserve a FEMA check before anything else in Greene County. Don't assume a tract around Greeneville is clear since its road frontage sits high. A low spot on a Greene County tract outside any mapped zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
When the map affects a deal
Here's why the zone matters at a closing in Tusculum. When a Greene County home falls inside an A or V zone and secures a loan from a federally regulated or insured lender, flood insurance is mandatory, as long as Greene County or the town participates in the NFIP. For a county home in shaded or unshaded X, coverage is optional; pricing a policy for land near Greeneville is still worth a call. Think the map is wrong about a house in Tusculum? FEMA's LOMA process allows a review, generally backed by an elevation certificate from a surveyor who works in Greene County. Placing fill on low ground near Tusculum often requires a permit and an elevation check; the county floodplain administrator can say what applies.
Tracts that cross the Greene County line
Greene County borders Madison County, NC, Cocke County, Hamblen County, Hawkins County, and Unicoi County, and each keeps its own parcel map and records. Our Tennessee page links each map neighboring Greene County.
