If a legal description for land in Pekin cites a lot number, the Pekin plat map is where those numbers come from. In this city guide: where to request a copy, plat versus tax map, and the details that matter to buyers around Marquette Heights.
Tracking down the Pekin plat map
For a subdivision near East Peoria, the deed usually cites the plat; that makes the request quick.
Pulling up a parcel
Begin with the Tazewell County ArcGIS parcel map; it covers every assessed parcel in the county, Tremont included. If the land is near Marquette Heights, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Closer to Tremont, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Creve Coeur, though signal can drop in rural spots. A screenshot of the parcel near North Pekin with its ID helps when you meet an owner or agent.
