When a deed near Charlack says lot and block, you'll need the Overland plat map to make sense of it. What this Overland guide covers: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
The Overland plat map: start here
For land around Vinita Park, the deed usually cites the plat; use it to request a copy.
The free map to start with
Begin with the St. Louis County ArcGIS parcel map; it includes every tax parcel around Vinita Park and Charlack. If you're looking near St. John, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. On ground around Vinita Park, a pop-up or side panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Replats and vacations
An amended plat may change lots around Vinita Park, search the index for replats of the same subdivision; street vacations near Breckenridge Hills show up in the records too.
Overland and the county around it
Overland is part of St. Louis County, Missouri, so its parcels are on the county's map. For a tract near Vinita Park, 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. Acreage past the town limits out by Vinita Park often falls under county rules instead.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Charlack, but coverage can be spotty out of town. A saved image of the lot near Vinita Park and its lines is a good backup.
Land outside a subdivision
Rural land near Charlack that was never subdivided may have no plat at all; look for a recorded survey for land near Sycamore Hills.
A quick look at the area
Clayton holds the county offices, home to the main records offices. You'll also find Sycamore Hills, Breckenridge Hills, Charlack, and Vinita Park, each with its own cluster of lots. About 987,059 people live in St. Louis County (Census Bureau estimate, 2023) across some 508 square miles. St. Louis County dates to 1812, and some chains of title near Charlack are long. Features like Spanish Lake Park and Babler State Park are easy to spot when you zoom out from St. John.
Where the recorded documents are
Before you sign anything, pull the recorded deed from the Recorder of Deeds; the parcel line is a drawing of it, which applies near Olivette as much as anywhere. For a home near Charlack, have ready the document number from the tax record so staff can find the deed fast.
Recorded plat or GIS layer
When the two disagree for a lot near Charlack, trust the recorded documents over the GIS layer.
A word on accuracy
The acreage figure is an assessed number; only a licensed surveyor can set the real boundary on land around Sycamore Hills. Near Vinita Park, records update in batches, so a deed recorded last month might lag behind.
Reading the legal description
Missouri is laid out under the Public Land Survey System, which means a tract near Charlack is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near St. John vary in size. Copy the legal description from the record for the parcel near St. John when you talk to a surveyor.
Who handles what
Questions about value or the owner field for land near Charlack belong with the County Assessor, which maintains the tax roll. Questions about what you can build around Sycamore Hills go to planning, building or health offices, and the answer depends on jurisdiction.
What a plat shows
If the land is near St. John, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
When a parcel crosses a boundary
St. Louis County meets Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County, and each of those keeps its own parcel map. Acreage along the edge near St. John may be split in two county records, so look at the neighboring map as well. For a tract near Sycamore Hills, the Platbookmapper state page links every bordering county map for Missouri.
Ordering the Overland plat map
The Recorder of Deeds may have searchable images, while others require a visit or a request; copy fees are usually small.

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.
