What the flood zone letters mean
For a lot in Bean Station, the label matters more than the color: A and V zones are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Zone AE near Blaine means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Blaine in shaded X (Zone B on older maps) is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Clear, unshaded X near Bean Station is outside the 500-year floodplain.
Creeks, rivers and low ground in Grainger County
In Grainger County, look closest at tracts along Clinch River, Holston River and Cherokee Lake. On many properties around Bean Station, the zone covers the low ground by the water while the homesite near the road is outside it. A creek near Blaine that displays no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
A short buyer checklist for Blaine
Request any past flood claims history for a Grainger County property before closing; it tells you more than the map alone. Then call an insurance agent who writes policies around Blaine and get a quote using the zone and the county parcel address.
What a flood zone means for a Grainger County buyer
Here's why the zone matters at a closing in Bean Station. If a house near Blaine sits in a Special Flood Hazard Area and carries a federally backed mortgage, flood insurance is mandatory; that applies where the local government around Blaine is in the National Flood Insurance Program. For a Grainger County home in shaded or unshaded X, federal rules do not require a policy, although a lender in Tennessee can still ask for it. If a building near Blaine sits above the flood line, FEMA's LOMA process allows a review, supported by elevation data from a licensed surveyor. Building or filling inside a mapped zone near Bean Station frequently requires a permit and an elevation check, and the building office serving Blaine explains the steps.
