Weighing a property around Montier? Checking the Shannon County flood zone map reveals whether it sits in a FEMA flood zone, and the lookup is free. Covered here for the county: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Shannon County BreezeMaps viewer, at least around Summersville.
Getting started with the Shannon 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 Alley Spring included. A tract near Birch Tree without an address can still be found: search the nearest road then click the parcel area.
The free map to start with
Lots and tracts near Winona can be looked up on the Shannon County BreezeMaps viewer, free to use and open without a login. On ground around Montier, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Eminence, copy the parcel ID before closing the panel; each clerk in the county asks for it first.
Land on the county line
The county touches Carter County, Dent County, Howell County, Oregon County, and Reynolds County; every one of them runs a separate parcel map around Summersville. Ground near Delaware that runs to the line can be split across two assessors' files, so open the neighboring map as well. On ground around Delaware, our state page lists every neighboring county map across Missouri.
How land is described here
Missouri uses the Public Land Survey System, which means a tract near Summersville is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Akers can be irregular. Copy the legal description from the record for the parcel near Akers for any title or survey request.
Beyond the mapped zones
Creeks and ditches near Winona aren't always studied in detail, so walk the land after rain. Wetlands near Mark Twain National Forest can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Offices that can help
Anything recorded against property around Alley Spring come from the Recorder of Deeds, sometimes only in person. Building or septic questions for a lot near Birch Tree need the planning or permitting office, depending on whether the land is inside town limits.
What the zone letters mean
Out toward Bartlett, A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. In and around Akers, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Mark Twain National Forest, though signal can drop in rural spots. A screenshot of the parcel near Summersville with its ID helps when you meet an owner or agent.
The paper trail behind a parcel
If the land is near Alley Spring, the map is an index, not the title: recorded deeds, subdivision plats and easements for parcels in the county are filed with the Recorder of Deeds. Long-held tracts near Montier can sit on a long string of deeds, and a title company is worth hiring on a real sale.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Shannon County BreezeMaps viewer for the outline of the tract near Winona.
A short flood checklist
Near Birch Tree, ask the seller for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.
Lenders and permits
For a structure inside an A or V zone and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, for land near Birch Tree included. Remodeling a house in a zone near Birch Tree often needs a floodplain permit; call the permitting office early.
