How to check the Sequatchie County flood zone map
Start at the FEMA Flood Map Service Center and enter the property address in Brush Creek or anywhere else in the county. If a piece of ground near Dunlap has no street number yet, search the nearest road and pan to it. For an interactive view of the county, the National Flood Hazard Layer viewer is easier to use, so you can see if the shading reaches a house near Dunlap. Then open the Tennessee Property Viewer for Sequatchie County to confirm the parcel near Brush Creek. Match the Sequatchie County lines and acreage to the FEMA view, since flood maps do not draw property lines in detail.
Opening the Sequatchie County parcel viewer

Our Sequatchie County, TN page keeps the official link and the maps next door to Dunlap in one place.
What the flood zone letters mean
For a lot in Brush Creek, the label matters more than the color: A and V zones are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Where a Sequatchie County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Land near Dunlap in shaded X (Zone B on older maps) is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Dunlap is minimal risk.
Deeds and plats behind the Sequatchie County map
Deeds and plats behind the Sequatchie County map are kept by the county's recording office; the official Sequatchie County website names which office that is. Easements and access rights near Lone Oak live in recorded documents, so read the deed, not just the county map.

Creeks, rivers and low ground in Sequatchie County
Parcels touching Sequatchie River deserve a FEMA check before anything else in Sequatchie County. Waterfront and bottomland parcels near Brush Creek commonly carry a zone along one edge, so check where the buildable part sits. A creek near Dunlap that displays no detailed zone, which is why it is worth walking the ground after a heavy rain.

What a flood zone means for a Sequatchie County buyer
Here's why the zone matters at a closing in Brush Creek. Where a building in Brush Creek falls inside an A or V zone and carries a federally backed mortgage, federal rules call for flood insurance, as long as Sequatchie County or the town participates in the NFIP. For a Sequatchie County home in shaded or unshaded X, federal rules do not require a policy, although a lender in Tennessee can still ask for it. When a county homesite is on a rise inside a mapped zone, a Letter of Map Amendment request is the formal route; a surveyor near Dunlap can supply the elevation data. Adding on to a house near Dunlap inside the zone commonly requires a permit and an elevation check, so call the county or the town office in Brush Creek before work starts.
