The printed Tazewell County plat book and the online parcel map answer the same question, who owns the land near Deer Creek, in different ways. This guide covers finding a printed edition for Tazewell County, Illinois, and using the free parcel map in the meantime.
What a Tazewell County plat book is
Think of the Tazewell County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Creve Coeur. Deeds and recorded plats, not the atlas, still govern land near Schaeferville in the county.
Finding the tract on the Tazewell County map
Tazewell County publishes its parcels on the Tazewell County ArcGIS parcel map, which runs on an Esri ArcGIS web map, free to use for a lot in Washington or a tract around Pekin. Use the search box for an address in Washington or a parcel number, or simply zoom in and click a tract around Pekin. For a backup route to the map covering Pekin, our Tazewell County directory entry keeps the link current.
Current and older editions
Private publishers have printed plat books for many rural counties, but editions for Tazewell County come and go; inquire at the courthouse, the extension office or a farm supply store in Deer Creek. Collectors and genealogists prize old Tazewell County atlases as they show farm names and owners near Schaeferville long before online maps.
Current owners without a printed book
For current ownership, the free Tazewell County ArcGIS parcel map beats any printed book: owners update as deeds are processed, and you can click any tract around Deer Creek. Pair the county map with a road atlas for the back roads near Creve Coeur.
Towns and land across Tazewell County
Town lots cluster around Pekin, the county seat, and Delavan, East Peoria, Marquette Heights, and Washington. Unincorporated communities in the county, including Heritage Lake, Groveland, and Schaeferville, show up as small groups of parcels along the roads. Roughly 646 square miles of land and about 129,541 residents (2023 estimate) make up Tazewell County. The Tazewell County map mixes subdivision lots near Delavan with farm and wooded tracts farther out. With a founding date of 1827, Tazewell County has long chains of title on some rural tracts.
Reading a Tazewell County atlas page
Many atlases add rural residence listings and road maps, handy on back roads near Schaeferville. Small parcels and town lots in Delavan are commonly too small to label on an atlas page, which is another reason the online map is better for them. If you use a plat book for hunting permission near Delavan, recheck the titleholder on the county map first.
