Weighing a property around Dixie? The Obion County flood zone map tells you whether it sits in a FEMA flood zone, and the lookup is free. Covered here for Obion County: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Tennessee Property Viewer.
The Obion County flood zone map: start here
Closer to Protemus, flood zones come from FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Rural land near Protemus with no street number is still easy to locate: zoom in from US Route 45W and click the spot.
Where the parcel data lives
Your first stop is the Tennessee Property Viewer; it maps each assessed parcel from Kenton to Cunningham. When a rural tract has no street number, follow US Route 45W on the aerial and select the outline, which applies near Dixie as much as anywhere. If the land is near Protemus, write down the parcel ID from that panel; each records desk in the county asks for it first.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Walnut Log, but coverage can be spotty out of town. A saved image of the lot near Walnut Log and its lines helps when you meet an owner or agent.
Decoding the flood zone labels
For acreage around Dixie, any A or V zone are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For a home near Rives, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X is minimal risk.
Recorded documents worth pulling
Before you sign anything, request the recorded deed through the Register of Deeds; the parcel line is a drawing of it, which applies near Reelfoot Lake State Park as much as anywhere. For land near Walnut Log, use the document number listed on the parcel record so staff can find the deed fast.
A short flood checklist
For acreage around South Fulton, ask the seller for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.
Limits of the parcel data
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real lines for a parcel near Reelfoot National Wildlife Refuge. For a home near South Fulton, records update in batches, so a deed recorded last month may not show yet.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the Tennessee Property Viewer too for the outline of the tract near South Fulton.
How land is described here
Older tracts around Protemus commonly use metes-and-bounds descriptions, which trace the boundary call by call. Platted lots around Reelfoot Lake State Park are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Cunningham before you request a deed or survey.
Getting answers from the right desk
Recorded documents for a parcel near Walnut Log are with the Register of Deeds, usually searchable by name or document number. Building or septic questions for a lot near Woodland Mills are for the local planning and health departments, and the answer depends on jurisdiction.

Insurance, lenders and building

Low spots and local drainage
Low-lying fields near Midway may not have detailed mapping, so look for water marks and debris lines. Wetlands near South Fulton can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
