If a legal description for land in Kewanee cites a lot number, the Kewanee plat map is where those numbers come from. In this Kewanee guide: where plats are filed, plat versus tax map, and what to look for on the sheet.
Tracking down the Kewanee plat map
For land around Annawan, look for the plat book reference on the parcel record; use it to request a copy.
The viewer Henry County publishes
The public parcel map for this area is the Henry County WTH GIS map, and anyone can open it without signing up. On ground around Galva, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Galva, write down the parcel ID from that panel; every office in the county uses it to find the file.
Kewanee and the county around it
Kewanee lies within Henry County, Illinois, so its parcels are on the county's map. On ground around Geneseo, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits near Bishop Hill usually falls under county rules rather than the town's.
Two different maps
The Henry County WTH GIS map draws parcels for taxes, while the recorded plat is the legal document.
Limits of the parcel data
Acreage on the record is a tax-roll number; only a licensed surveyor sets the real corners for a parcel near Galva. In and around Galva, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Getting your bearings
Cambridge holds the county offices, which is where the courthouse records live. Other places on the map include Galva, Bishop Hill, Annawan, and Atkinson, where town lots give way to larger tracts. Around 48,448 people call Henry County home (Census estimate, 2023) on roughly 823 square miles. Henry County was formed in 1825, and some chains of title near Geneseo are long.
Amended plats
An amended plat may change lots around Geneseo, so check for later filings; street vacations show up in the records too.
How land is described here
Illinois is laid out under the Public Land Survey System, so deeds around Annawan reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Annawan odd-sized. Keep the legal description for land near Annawan when you talk to a surveyor.
Deeds, plats and who keeps them
When the details count, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Bishop Hill only summarizes it. Long-held tracts around Atkinson may sit on many deeds, and a title company earns its fee on a real sale.
Reading the plat sheet
With a lot near Galva, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Getting a copy
Out toward Geneseo, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.
When there's no plat
Acreage around Annawan outside a subdivision may have no plat at all; the deed and any recorded survey describe it instead.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Annawan, so load it before you lose signal. A saved image of the lot near Annawan and its lines is a good backup.
Who handles what
If the acreage or value on a parcel near Galva looks off go to the Supervisor of Assessments, working with township assessors, the office behind the parcel record. Questions about what you can build around Annawan go to planning, building or health offices, town or county, depending on location.
Next door to Henry County
Henry County borders Bureau County, Knox County, Mercer County, Rock Island County, and Stark County, and each of those keeps its own parcel map. Ground near Cambridge that runs to the line may be split across two assessors' files, so look at the neighboring map before you assume the acreage. Out toward Bishop Hill, the Platbookmapper state page links every bordering county map for Illinois.

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.
