Ahead of any purchase around Falcon, check the McNairy County flood zone map: the zone on that map shapes insurance, permits and resale. In this McNairy County guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Tennessee Property Viewer.
Getting started with the McNairy County flood zone map
For parcel-by-parcel detail, open the National Flood Hazard Layer viewer, where zone shading sits over a photo base, for land near Selmer included. Rural land near Guys with no street number is still easy to locate: zoom in from the nearest road then click the parcel area.
Getting to the right map
If you're looking near Caffey, the official parcel map for this area is the Tennessee Property Viewer, and no login is needed to use it. In and around Caffey, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Acton, copy the parcel ID from that panel; each office in the county uses it to find the file.
Questions to ask before you buy
If you're looking near Selmer, ask the listing agent for any Elevation Certificate before closing; an insurance quote early avoids surprises.
Zones on the McNairy County flood zone map
On ground around Leapwood, zones beginning with A or V mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. With a lot near Big Hill Pond State Park, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
What the map can't tell you
If the land is near Eastview, acreage on the record is an assessed number; only a licensed surveyor can set the real lines on the ground. If the land is near Adamsville, records update in batches, so a deed recorded last month might lag behind.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Adamsville, so load it before you lose signal. A screenshot of the parcel near Eastview with its ID helps when you meet an owner or agent.
Water near Falcon
Creeks and ditches near Falcon aren't always studied in detail, so walk the land after rain. Wetlands near Big Hill Pond State Park can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
How land is described here
Tracts outside towns near Guys are often described by metes and bounds, listing bearings, distances and landmarks. Town lots near Guys are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Finger before you request a deed or survey.
Recorded documents worth pulling
Out toward Caffey, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county are kept by the Register of Deeds. Inherited tracts near Big Hill Pond State Park can sit on many deeds, so a title company earns its fee on a real sale.
Getting your bearings
Selmer serves as the county seat, home to the main records offices. Other places on the map include Adamsville, Bethel Springs, Ramer, and Eastview. Around 26,163 people live in McNairy County (Census Bureau estimate, 2023) spread over about 563 square miles. McNairy County was formed in 1823, which matters when you trace an old farm's title. Features like Big Hill Pond State Park are easy to spot when you zoom out.
Getting answers from the right desk
For assessment questions about property around Big Hill Pond State Park belong with the Assessor of Property, which maintains the tax roll. Zoning, permits and septic questions near Falcon go to planning, building or health offices, town or county, depending on location.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so pair it with the Tennessee Property Viewer to confirm you have the right parcel near Leapwood.
Money questions tied to the zone
For a structure inside an A or V zone and the loan is federally backed or regulated, mandatory purchase rules apply in communities in the NFIP, for land near Big Hill Pond State Park included. New construction in a floodplain near Bethel Springs can trigger elevation rules; check with the county or town building office before you plan.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
