Ahead of any purchase around Leadwood, check the Bonne Terre flood map: FEMA's zone label affects insurance, building rules and resale. This Bonne Terre guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the St. Francois County CAMAvision map.
Checking the Bonne Terre flood map step by step
Start with FEMA's Flood Map Service Center: type an address near Park Hills, and choose the dynamic map. Vacant ground around Desloge can still be found: zoom in from the nearest road and click inside the land.
Getting to the right map
Begin with the St. Francois County CAMAvision map; it includes each tax parcel in the county, Leadington included. For acreage around Leadington, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Farmington, the parcel card usually lists the owner of record, acreage on the tax roll, the parcel number and often a sale date.
St. Francois County in a few facts
Farmington holds the county offices, which is where the courthouse records live. You'll also find Desloge, Leadwood, Leadington, and Park Hills, each with its own cluster of lots. Around 67,058 people call St. Francois County home (Census Bureau estimate, 2023) across roughly 452 square miles. St. Francois County dates to 1821, and some chains of title near Park Hills are long. Features like Mark Twain National Forest make handy reference points on the map near Farmington.
A short flood checklist
Ask the seller for any Elevation Certificate on the property near Park Hills; getting a quote early avoids surprises.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Desloge, so load it before you lose signal. A screenshot of the parcel near Leadwood with its ID helps when you meet an owner or agent.
Bonne Terre, MO: the basics
Bonne Terre sits in St. Francois County, Missouri, so its parcels are on the county's map. For land near Desloge, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the city limits toward Bismarck generally answers to county rules rather than the town's.
Zones on the Bonne Terre flood map
For a parcel near Desloge, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. Out toward Desloge, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Low spots and local drainage
Low-lying fields near Park Hills aren't always studied in detail, so walk the land after rain. Wet ground around Park Hills is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the St. Francois County CAMAvision map to see exactly which lot near Leadington you're looking at.
How land is described here
Missouri is laid out under the Public Land Survey System, so deeds around Park Hills reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Desloge can be irregular. Keep the legal description for land near Leadwood for any title or survey request.
What the map can't tell you
Listed acreage is an estimate; only a licensed surveyor can set the real lines on land around Leadwood. On ground around Leadwood, records update in batches, so a deed recorded last month can take weeks to appear.
Which office to call
Questions about value or the owner field for land near Leadington are handled by the County Assessor, which maintains the tax roll. Zoning, permits and septic questions near Leadwood are for the local planning and health departments, depending on whether the land is inside town limits.
Money questions tied to the zone
Out toward Farmington, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Building or adding on near Farmington in a mapped zone usually means extra permit review; check with the county or town building office before you plan.
Quick answers
What is a LOMA near Leadwood?
Short answer: FEMA's LOMA process is the usual route when a building near Farmington sits above the base flood elevation, and lenders accept the result.

Generally, a new study can move a zone line near Park Hills; your community is notified before changes take effect.

How do I save a parcel from the viewer for land near Park Hills?
