If a legal description for land in Pontiac cites a lot number, the Pontiac plat map is where those numbers come from. Covered here for Pontiac: where to request a copy, plat versus tax map, and what to look for on the sheet.
Who keeps the Pontiac plat map
For a lot in Pontiac, the deed usually cites the plat; that makes the request quick.
The free map to start with
Begin with the Livingston County CAMAvision map; it covers each assessed parcel from Long Point to Saunemin. Without an address in hand, follow US Route 24 on the aerial and click the parcel itself. Out toward Odell, the parcel card usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Legal descriptions in Illinois
Illinois uses the Public Land Survey System, which means a tract near Flanagan is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Long Point vary in size. Keep the legal description for land near Cornell when you talk to a surveyor.
Limits of the parcel data
The acreage figure is a tax-roll number; only a licensed surveyor sets the real lines on land around Long Point. For property near Saunemin, records update in batches, so a deed recorded last month can take weeks to appear.
Where Pontiac fits in
Pontiac is part of Livingston County, Illinois, so its parcels are on the county's map. The town is also the county seat, so deeds and plats are filed in town, especially near Streator. If you're looking near Odell, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the city limits out by Cornell usually follows county rules instead.
Replats and vacations
Lots near Fairbury can be combined or reconfigured by a replat, search the index for replats of the same subdivision; street vacations near Long Point show up in the records too.
Plat map vs. parcel map
Where lines don't match in Pontiac, trust the recorded documents over the GIS layer.
Land outside a subdivision
Rural land near Long Point that was never subdivided may have no plat at all; look for a recorded survey for land near Odell.
Where the recorded documents are
Before you sign anything, get the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Cornell only summarizes it. Inherited tracts around Saunemin may trace back through many deeds, and a title company can sort it out if money is changing hands.
When a parcel crosses a boundary
Livingston County meets Ford County, Grundy County, Kankakee County, LaSalle County, and McLean County, and each of those keeps its own parcel map. A tract near the line by Odell can be split in two county records, so open the neighboring map before you assume the acreage. If the land is near Saunemin, our state page lists each neighboring county map for Illinois.
