When a listing near Ashmore mentions a lot number, the Mattoon plat map is where those numbers come from. What this Mattoon guide covers: where plats are filed, how a plat differs from a parcel map, and the details that matter to buyers.
Getting started with the Mattoon plat map
For a subdivision near Ashmore, look for the plat book reference on the parcel record; use it to request a copy.
Where the parcel data lives
Go first to the Coles County ArcGIS parcel map; it covers every tax parcel around Charleston and Humboldt. Out toward Charleston, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Humboldt, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Sections, lots and bearings
Illinois is laid out under the Public Land Survey System, so rural legal descriptions near Humboldt cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Ashmore odd-sized. Write down the legal description for the tract near Ashmore when you talk to a surveyor.
Where Mattoon fits in
Mattoon lies within Coles County, Illinois, and the county assessor maps its lots. If you're looking near Oakland, 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. Lots just outside the town limits near Charleston usually falls under county rules, not municipal ones.
Who handles what
Anything recorded against property around Humboldt are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), usually searchable by name or document number. Questions about what you can build around Ashmore go to planning, building or health offices, depending on whether the land is inside town limits.
Before you lean on the lines
Acreage on the record is an assessed number; just a licensed surveyor sets the real lines for a parcel near Lerna. In and around Ashmore, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Land on the county line
Coles County touches Clark County, Cumberland County, Douglas County, Edgar County, and Moultrie County, and each of those keeps its own parcel map. A tract near the line by Lerna can show up in two county records, so look at the neighboring map too. On ground around Charleston, our state page links each bordering county map for Illinois.
Recorded plat or GIS layer
Where lines don't match in Mattoon, go with the plat and a surveyor's work.
Metes and bounds instead
Acreage around Lerna outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Charleston.
Recorded documents worth pulling
The map is an index, not the title: deeds, plats and easements covering ground around Lerna sit with the county Recorder of Deeds (in many counties the County Clerk and Recorder). If you're looking near Charleston, have ready the instrument number shown in the record panel to skip a name search.
Replats and vacations
An amended plat may change lots around Humboldt, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Details on the Mattoon plat map
Utility or drainage strips on a lot in Mattoon limit where you can build or fence; read the notes on the sheet.

Field tips
