When a deed near Olivette says lot and block, the Creve Coeur plat map is where those numbers come from. What this Creve Coeur guide covers: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
The Creve Coeur plat map: start here
For a subdivision near Country Life Acres, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
The free map to start with
Begin with the St. Louis County ArcGIS parcel map; it covers every assessed parcel around Westwood and Town and Country. Out toward Westwood, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Frontenac, the record panel typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Where Creve Coeur fits in
Creve Coeur lies within St. Louis County, Missouri, which means parcel data comes from the county. For a tract near Town and Country, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the town limits out by Olivette generally falls under county rules instead.
How land is described here
Missouri follows the Public Land Survey System, so rural legal descriptions near Town and Country cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Westwood can be irregular. Write down the legal description for the tract near Olivette for any title or survey request.
Metes and bounds instead
Acreage around Crystal Lake Park outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.

Plat map vs. parcel map
If the tax map and plat differ near Town and Country, go with the plat and a surveyor's work.
When a plat changes
Lots near Olivette can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
What a plat shows

Using it on a phone
Most viewers work in a phone browser, useful out on a road near Country Life Acres, though signal can drop in rural spots. A printout of the tract near Olivette keeps working without signal.
Offices that can help
If the acreage or value on a parcel near Crystal Lake Park looks off are handled by the County Assessor, since that office keeps the assessment data. Questions about what you can build around Westwood need the planning or permitting office, and the answer depends on jurisdiction.
Before you lean on the lines
Acreage on the record is an assessed number; just a licensed surveyor establishes the real boundary for a parcel near Country Life Acres. For land near Westwood, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Requesting the plat
For a parcel near Frontenac, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.

The paper trail behind a parcel

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.
