For any lot around Hudson, a look at the Bloomington GIS map gives you lines, owner names and parcel numbers. This Bloomington guide covers: where that map lives, the fastest ways to search, and the limits worth knowing.
Opening the Bloomington GIS map: start here
For land near Towanda, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The free map to start with
Go first to the McLean County ArcGIS parcel map; it includes every assessed parcel in the county, Towanda included. For a tract near Downs, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Downs, a pop-up or side panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Bloomington, IL: the basics
The city is part of McLean County, Illinois, which means parcel data comes from the county, especially near El Paso. As the county seat, Bloomington hosts the courthouse, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by. Local government in Bloomington handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the town limits out by Towanda usually follows county rules, not municipal ones.
Saving what you find
Save a screenshot of the lot near Carlock and its record panel, which helps later when you ask the assessor or a title company.
Searching the map
Addresses are the easiest route inside Bloomington; owner search often wants the surname first. In and around Carlock, searching by parcel number never misses, and you'll find it on tax statements.
Land on the county line
McLean County borders Champaign County, De Witt County, Ford County, Livingston County, and Logan County; every one of them runs a separate parcel map. Acreage along the edge near Downs can be split in two county records, so open the adjacent map as well. With a lot near Downs, the Platbookmapper state page links each bordering county map across Illinois.
Limits of the parcel data
Parcel lines are drawn for taxes, not surveyed, so a fence near Normal may sit a few yards off the line on screen. Near Carlock, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Browser tips
When the map won't open around Carlock, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
What the layers show
An aerial view around Hudson helps you see where buildings sit inside the lines.

Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements for land near Towanda are kept by the county Recorder of Deeds (in many counties the County Clerk and Recorder). For land near Heyworth, have ready the document number listed on the parcel record to skip a name search.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Heyworth, so load it before you lose signal. A printout of the tract near Normal keeps working without signal.
Inside the parcel card
If sale dates appear, they help gauge the market in this city are a useful starting point; an appraiser is the real authority, especially near Anchor.
