For any lot around Clarkson Valley, the Wildwood GIS map lays out lines, owner names and parcel numbers. What this Wildwood guide covers: which viewer to open, the fastest ways to search, and what to double-check with records.
Opening the Wildwood GIS map
Closer to Ellisville, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The viewer St. Louis County publishes
The public parcel map for this area is the St. Louis County ArcGIS parcel map, and no login is needed to use it. Without an address in hand, follow Interstate 64 on the aerial and select the outline. For a tract near Winchester, write down the parcel ID from that panel; each office in the county uses it to find the file.
Legal descriptions in Missouri
Missouri is laid out under the Public Land Survey System, so deeds around Ellisville reference sections and townships. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Eureka can be irregular. Copy the legal description from the record for the parcel near Ballwin before you request a deed or survey.
Troubleshooting the viewer
When the map won't open around Ellisville, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
City limits and county records
Wildwood sits in St. Louis County, Missouri, which means parcel data comes from the county. For acreage around Ellisville, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the city limits out by Eureka often follows county rules instead.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Clarkson Valley, so load it before you lose signal. A screenshot of the parcel near Ellisville with its ID is a good backup.
Finding the right lot
For a house in Wildwood, search the street address; for owner searches, try last name first. Out toward Ellisville, searching by parcel number never misses, and you'll find it on tax statements.
A quick look at the area
Clayton serves as the county seat, home to the main records offices. You'll also find Ellisville, Clarkson Valley, Eureka, and Ballwin, where town lots give way to larger tracts. Around 987,059 people call St. Louis County home (Census Bureau estimate, 2023) spread over some 508 square miles. St. Louis County was formed in 1812, and some chains of title near Ballwin are long. Places such as Spanish Lake Park and Babler State Park make handy reference points on the map near Chesterfield.
Beyond the parcel lines
Out toward Eureka, look in the layer list for municipal boundaries, floodplain and sometimes zoning; not every viewer has them all.
Limits of the parcel data
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real boundary for a parcel near Eureka. Closer to Clarkson Valley, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Keeping a record
Save a screenshot of the lot near Eureka and its record panel, so you have it when calling an office.
When a parcel crosses a boundary
St. Louis County touches 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 Chesterfield may show up in two county records, so open the adjacent map as well. For a home near Ballwin, the Platbookmapper state page links each bordering county map for Missouri.
What the record panel tells you
Recent sales on nearby lots around Chesterfield give a rough idea of values; an appraiser is the real authority.
Who handles what
Questions about value or the owner field for land near Chesterfield are handled by the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Ellisville go to planning, building or health offices, depending on whether the land is inside town limits.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Ballwin sit with the Recorder of Deeds. In and around Clarkson Valley, have ready the book and page from the tax record so staff can find the deed fast.

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.
