Weighing a property around Leadington? A quick look at the Farmington flood zone map shows whether FEMA puts it in a high-risk zone, and it costs nothing to check. In this Farmington guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the St. Francois County CAMAvision map.
Where the Farmington flood zone map lives
Start with FEMA's Flood Map Service Center: type an address near Leadwood, and choose the dynamic map. Vacant ground around Desloge is still easy to locate: pan from the closest town then click the parcel area.
Where the parcel data lives
Go first to the St. Francois County CAMAvision map; it maps every assessed parcel from Leadwood to Leadington. Around Bismarck, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Bonne Terre, the record panel typically gives the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Which office to call
For assessment questions about property around Park Hills belong with the County Assessor, the office behind the parcel record. Zoning, permits and septic questions near Desloge need the planning or permitting office, and the answer depends on jurisdiction.
Farmington and the county around it
Farmington is part of St. Francois County, Missouri, which means parcel data comes from the county. Farmington is also the county seat, so deeds and plats are filed in town. For acreage around Leadwood, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits out by Leadwood generally answers to county rules instead.
Reading A, AE and X
An AE label includes a base flood elevation (BFE), and an unnumbered A zone has none; builders around Leadington design to it. For a tract near Bismarck, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Beyond the mapped zones
Low-lying fields near Bismarck may not have detailed mapping, so walk the land after rain. Marshy spots near Park Hills can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Deeds, plats and who keeps them
When the details count, pull the recorded deed from the Recorder of Deeds; the parcel map near Bismarck only summarizes it. With a lot near Leadwood, use the book and page from the tax record so staff can find the deed fast.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the St. Francois County CAMAvision map to confirm you have the right parcel near Leadwood.
Getting your bearings
Farmington serves as the county seat, where most land records are kept. Smaller places on the map include Leadington, Park Hills, Desloge, and Leadwood, each with its own cluster of lots. Roughly 67,058 people call St. Francois County home (Census estimate, 2023) across some 452 square miles. St. Francois County dates to 1821, and some chains of title near Leadwood are long. Features like Mark Twain National Forest make handy reference points on the map near Desloge.
Limits of the parcel data
The acreage figure is a tax-roll number; only a licensed surveyor can set the real corners for a parcel near Park Hills. Owner names and values update on a schedule, so a recent sale near Bonne Terre might lag behind.
Insurance, lenders and building
For acreage around Bismarck, ask for an Elevation Certificate: it records the building's elevation against the base flood. New construction in a floodplain near Bismarck can trigger elevation rules; ask the local floodplain administrator early.
What to request from a seller
Ask the listing agent whether the home has flooded on the property near Bonne Terre; getting a quote early avoids surprises.
Land on the county line
St. Francois County meets Iron County, Jefferson County, Madison County, Perry County, and Ste. Genevieve County, all with their own assessor records. Ground near Leadwood that runs to the line can show up in two county records, so check the neighboring map as well. For a parcel near Desloge, our state page lists each bordering county map for Missouri.
