When a deed near Kangley says lot and block, look up the Streator plat map it refers to. In this Streator guide: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
Getting started with the Streator plat map
For a subdivision near Lostant, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
The free map to start with
Begin with the LaSalle County parcel viewer; it includes each assessed parcel from Wenona to Leonore. For land near Leonore, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. In and around Ransom, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
When there's no plat
Acreage around Grand Ridge outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Kangley.
A quick look at the area
Ottawa holds the county offices, home to the main records offices. Smaller places on the map include Kangley, Grand Ridge, Leonore, and Ransom, where town lots give way to larger tracts. About 108,309 people call LaSalle County home (Census Bureau estimate, 2023) across roughly 1,135 square miles. LaSalle County dates to 1831, and some chains of title near Lostant are long.
Where Streator fits in
Streator lies within LaSalle County, Illinois, which means parcel data comes from the county. For a tract near Wenona, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits out by Wenona often follows county rules instead.
Neighboring parcel maps
LaSalle County touches Bureau County, DeKalb County, Grundy County, Kendall County, and Lee County; every one of them runs a separate parcel map. Ground near Wenona that runs to the line can show up across two assessors' files, so check the neighboring map too. If the land is near Lostant, our state page lists every bordering county map for Illinois.
Deeds, plats and who keeps them
For anything that matters, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Grand Ridge only summarizes it. Inherited tracts near Ransom can trace back through many deeds, and a title company is worth hiring on a real sale.
How a plat differs from the tax map
The LaSalle County parcel viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
Reading the plat sheet
If the land is near Kangley, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Wenona, but coverage can be spotty out of town. A screenshot of the parcel near Kangley with its ID is a good backup.
Limits of the parcel data
The acreage figure is an assessed number; just a licensed surveyor establishes the real corners on land around Lostant. Closer to Kangley, records update in batches, so a deed recorded last month can take weeks to appear.
Replats and vacations
An amended plat may change lots around Lostant, search the index for replats of the same subdivision; street vacations near Wenona show up in the records too.
Offices that can help
Questions about value or the owner field for land near Kangley belong with the Supervisor of Assessments, working with township assessors, which maintains the tax roll. Building or septic questions for a lot near Leonore go to planning, building or health offices, and the answer depends on jurisdiction.
Getting a copy
For a parcel near Leonore, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.
Legal descriptions in Illinois
Illinois uses the Public Land Survey System, which means a tract near Lostant is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Grand Ridge vary in size. Keep the legal description for land near Lostant for any title or survey request.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
