The official viewer behind the Moline GIS map
For acreage around Rock Island, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Getting to the right map
Go first to the Rock Island County parcel viewer; it includes each assessed parcel in the county, Oak Grove included. With a lot near Carbon Cliff, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near East Moline, write down the parcel ID from that panel; each office in the county will want it.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Silvis, though signal can drop in rural spots. A screenshot of the parcel near Milan with its ID keeps working without signal.
Neighboring parcel maps
Rock Island County touches Henry County, Mercer County, Whiteside County, Clinton County, IA, and Louisa County, IA, and each of those keeps its own parcel map. Ground near Milan that runs to the line may be split across two assessors' files, so look at the neighboring map too. If the land is near Rock Island, the Platbookmapper state page links each bordering county map across Illinois.
City limits and county records
The city is part of Rock Island County, Illinois, which means parcel data comes from the county, especially near Silvis. Near Rock Island, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits out by East Moline generally answers to county rules instead.
Search tips
For a house in Moline, search the street address; for owner searches, try last name first. With a lot near Milan, searching by parcel number never misses, and you'll find it on tax statements.
When the map won't load
When the map won't open around Carbon Cliff, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.

How land is described here
Illinois uses the Public Land Survey System, so deeds around Milan reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Carbon Cliff vary in size. Keep the legal description for land near Milan before you request a deed or survey.
What the map can't tell you
Listed acreage is an assessed number; just a licensed surveyor sets the real boundary on land around Rock Island. On ground around Rock Island, owner names and values update on a schedule, so a deed recorded last month might lag behind.
What the record panel tells you
Recent sales on nearby lots in this city give a rough idea of values; they're not an appraisal for land near Coal Valley.
Keeping a record
Print or screenshot the parcel near Oak Grove with its ID visible, which helps later when you ask the assessor or a title company.
Who handles what
For assessment questions about property around Silvis go to the Supervisor of Assessments, working with township assessors, since that office keeps the assessment data. Building or septic questions for a lot near Carbon Cliff go to planning, building or health offices, depending on whether the land is inside town limits.
A quick look at the area
Rock Island serves as the county seat, where most land records are kept. You'll also find Silvis, Milan, and Carbon Cliff, where town lots give way to larger tracts. Roughly 141,236 people call Rock Island County home (Census Bureau estimate, 2023) spread over roughly 427 square miles. Rock Island County dates to 1831, so old deeds can run back a long way. Landmarks such as Upper Mississippi River National Wildlife and Fish Refuge help you orient on the aerial around Carbon Cliff.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near Silvis are kept by the county Recorder of Deeds (in many counties the County Clerk and Recorder). Older tracts near Rock Island may sit on a long string of deeds, so a title company earns its fee if money is changing hands.

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.
