Trying to understand lot lines near Park Hills? Start with the Bonne Terre plat map, as it records the lot layout that deeds refer to. In this Bonne Terre guide: where to request a copy, plat versus tax map, and what to look for on the sheet.
Getting started with the Bonne Terre plat map
For land around Bismarck, look for the plat book reference on the parcel record; that makes the request quick.
Pulling up a parcel
Go first to the St. Francois County CAMAvision map; it includes each tax parcel in the county, Desloge included. When a rural tract has no street number, pan along the nearest road and click the parcel itself, whether the land is near Park Hills or elsewhere in the county. For a tract near Leadington, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Leadwood are kept by the Recorder of Deeds. Long-held tracts near Leadwood may trace back through a long string of deeds, so a title company earns its fee on a real sale.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Leadwood, but coverage can be spotty out of town. A screenshot of the parcel near Leadwood with its ID is a good backup.
Which office to call
Recorded documents for a parcel near Park Hills come from the Recorder of Deeds, usually searchable by name or document number. Zoning, permits and septic questions near Desloge are for the local planning and health departments, and the answer depends on jurisdiction.
Bonne Terre and the county around it
Bonne Terre is part of St. Francois County, Missouri, so its parcels are on the county's map. For a parcel near Leadwood, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits out by Desloge usually falls under county rules, not municipal ones.
Two different maps
The tax map on the St. Francois County CAMAvision map is a summary, while the recorded plat is the legal document.
Limits of the parcel data
Listed acreage is a tax-roll number; just a licensed surveyor establishes the real boundary for a parcel near Leadwood. Records update in batches, so a recent sale near Farmington might lag behind.
When a parcel crosses a boundary
St. Francois County meets Iron County, Jefferson County, Madison County, Perry County, and Ste. For a home near Leadwood, genevieve County, all with their own assessor records. Acreage along the edge near Leadington can be split across two assessors' files, so open the neighboring map before you assume the acreage.

Rural land near Farmington that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Ordering the Bonne Terre plat map
If you're looking near Leadwood, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.
