Getting to the right map
Go first to the Boone County ArcGIS parcel map; it maps every assessed parcel around Candlewick Lake and Garden Prairie. Without an address in hand, pan along Interstate 90 and select the outline. If the land is near Garden Prairie, copy the parcel ID from that panel; every clerk in the county asks for it first.
Offices that can help

Building or septic questions for a lot near Garden Prairie are for the local planning and health departments, town or county, depending on location.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Candlewick Lake, though signal can drop in rural spots. A saved image of the lot near Candlewick Lake and its lines helps when you meet an owner or agent.
Before you lean on the lines
For a tract near Herbert, listed acreage is an estimate; only a licensed surveyor establishes the real boundary on the ground. Closer to Garden Prairie, records update in batches, so a deed recorded last month may not show yet.
Sections, lots and bearings
Illinois is laid out under the Public Land Survey System, which means a tract near Belvidere is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Garden Prairie can be irregular. Write down the legal description for the tract near Blaine for any title or survey request.
What the deed may not include
Rights below the surface near Argyle may belong to someone else, so read the deed and ask the title company.
