Parcel maps here are usually run by the county, not the town, and for the city that means the around Deer Creek.Tazewell County ArcGIS parcel map.
Pulling up a parcel
Go first to the Tazewell County ArcGIS parcel map; it includes each tax parcel in the county, East Peoria included. For property near Marquette Heights, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For a parcel near Creve Coeur, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Pekin, IL: the basics
Pekin lies within Tazewell County, Illinois, and the county assessor maps its lots. As the county seat, Pekin hosts the courthouse, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by. If you're looking near Creve Coeur, 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. Land beyond the town limits near Tremont often answers to county rules instead.
Legal descriptions in Illinois
Illinois uses the Public Land Survey System, so rural legal descriptions near Creve Coeur cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Tremont can be irregular. Write down the legal description for the tract near East Peoria when you talk to a surveyor.
Saving what you find
Save a screenshot of the lot near Tremont and its record panel, so you have it when calling an office.
A word on accuracy
The acreage figure is an assessed number; only a licensed surveyor establishes the real corners on land around Marquette Heights. If the land is near East Peoria, records update in batches, so a deed recorded last month might lag behind.
Three ways to find a parcel
Vacant ground near Marquette Heights may lack an address, which means panning to it and clicking. In and around North Pekin, searching by parcel number never misses, and it's printed on tax bills.
Troubleshooting the viewer
When the map won't open around Creve Coeur, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Layers worth turning on
Switch to the aerial basemap over the city to compare lines with fences and driveways around Deer Creek.
Backing up the map with records
When the details count, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Marquette Heights only summarizes it. Long-held tracts near North Pekin may trace back through a long string of deeds, so a title company is worth hiring if money is changing hands.
Which office to call
If the acreage or value on a parcel near Creve Coeur looks off belong with the Supervisor of Assessments, working with township assessors, which maintains the tax roll. Building or septic questions for a lot near East Peoria are for the local planning and health departments, depending on whether the land is inside town limits.
Inside the parcel card
Recent sales on nearby lots near Creve Coeur give a rough idea of values; an appraiser is the real authority.
On site with the map
Most viewers work in a phone browser, useful out on a road near Marquette Heights, but coverage can be spotty out of town. A screenshot of the parcel near Creve Coeur with its ID helps when you meet an owner or agent.
When a parcel crosses a boundary
Tazewell County borders Fulton County, Logan County, McLean County, Mason County, and Peoria County; every one of them runs a separate parcel map. Acreage along the edge near Marquette Heights can show up across two assessors' files, so open the neighboring map as well. For a tract near East Peoria, the Platbookmapper state page lists each bordering county map across Illinois.
Getting your bearings
The city serves as the county seat, where most land records are kept for land near Washington. You'll also find North Pekin, Marquette Heights, Creve Coeur, and Tremont, each with its own cluster of lots. Roughly 129,541 people live in Tazewell County (Census estimate, 2023) across roughly 646 square miles. Tazewell County was formed in 1827, so old deeds can run back a long way.
