When a deed near Calverton Park says lot and block, the Ferguson plat map is where those numbers come from. In this Ferguson guide: where plats are filed, plat versus tax map, and the details that matter to buyers.
Getting started with the Ferguson plat map
For a subdivision near Kinloch, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
Opening the official parcel viewer
Your first stop is the St. Louis County ArcGIS parcel map; it maps every assessed parcel from Calverton Park to Berkeley. For acreage around Dellwood, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For a tract near Dellwood, the parcel card typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Berkeley, though signal can drop in rural spots. A printout of the tract near Calverton Park is a good backup.
City limits and county records
Ferguson sits in St. Louis County, Missouri, so its parcels are on the county's map. On ground around Berkeley, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the town limits near Berkeley usually answers to county rules instead.
Plat map vs. parcel map
If the tax map and plat differ near Country Club Hills, go with the plat and a surveyor's work.
How land is described here
Missouri is laid out under the Public Land Survey System, which means a tract near Calverton Park is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Dellwood can be irregular. Copy the legal description from the record for the parcel near Country Club Hills when you talk to a surveyor.
A quick look at the area
Clayton holds the county offices, which is where the courthouse records live. Smaller places on the map include Dellwood, Calverton Park, Kinloch, and Cool Valley. About 987,059 people call St. Louis County home (Census Bureau estimate, 2023) across roughly 508 square miles. St. Louis County was organized in 1812, and some chains of title near Country Club Hills are long. Features like Spanish Lake Park and Babler State Park are easy to spot when you zoom out from Kinloch.
Who handles what

A word on accuracy
Listed acreage is an assessed number; only a licensed surveyor establishes the real lines for a parcel near Cool Valley. For a tract near Berkeley, records update in batches, so a deed recorded last month might lag behind.
When a parcel crosses a boundary
St. Louis County borders Madison County, IL, Monroe County, IL, St. Clair County, IL, Franklin County, and Jefferson County, all with their own assessor records. Acreage along the edge near Berkeley may be split across two assessors' files, so check the adjacent map as well.

Land outside a subdivision
Acreage around Calverton Park outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
Recorded documents worth pulling
