When a listing near Carbon Cliff mentions a lot number, the Moline plat map is where those numbers come from. Covered here for the city: where plats are filed, plat versus tax map, and what to look for on the sheet for land near East Moline.
Tracking down the Moline plat map
For land around Rock Island, the deed usually cites the plat; use it to request a copy.
Getting to the right map
Property in and around Silvis are published on the Rock Island County parcel viewer, a viewer that needs no account. On ground around East Moline, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. Near Silvis, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and often a sale date.
Places you'll see on the map
Rock Island serves as the county seat, home to the main records offices. Other places on the map include Silvis, Milan, and Carbon Cliff, each with its own cluster of lots. About 141,236 people call Rock Island County home (Census Bureau estimate, 2023) across roughly 427 square miles. Rock Island County was organized in 1831, and some chains of title near Silvis are long. Features like Upper Mississippi River National Wildlife and Fish Refuge make handy reference points on the map near Silvis.
Sections, lots and bearings
Illinois uses the Public Land Survey System, so rural legal descriptions near Silvis cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Carbon Cliff can be irregular. Copy the legal description from the record for the parcel near Silvis before you request a deed or survey.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements for land near Carbon Cliff are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Long-held tracts around Oak Grove may go back through many deeds, so a title company can sort it out before a purchase.
Where Moline fits in
The city lies within Rock Island County, Illinois, which means parcel data comes from the county, especially near Coal Valley. Local government in Moline handles things like zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits near Carbon Cliff usually answers to county rules, not municipal ones.
Two different maps
The tax map on the Rock Island County parcel viewer is a summary, but the recorded plat is what the deed relies on.
What a plat shows
If you're looking near East Moline, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
A word on accuracy
The acreage figure is an estimate; only a licensed surveyor establishes the real boundary for a parcel near Carbon Cliff. For a home near Silvis, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Land outside a subdivision
Rural land near Oak Grove that was never subdivided is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Offices that can help
For assessment questions about property around Silvis belong with the Supervisor of Assessments, working with township assessors, the office behind the parcel record. Questions about what you can build around Carbon Cliff are for the local planning and health departments, and the answer depends on jurisdiction.
Land on the county line
Rock Island County meets Henry County, Mercer County, Whiteside County, Clinton County, IA, and Louisa County, IA, and each of those keeps its own parcel map. Ground near Oak Grove that runs to the line may show up across two assessors' files, so check the neighboring map as well. Near Rock Island, our state page lists each bordering county map for Illinois.
Getting a copy
If the land is near East Moline, some counties put plat images online, while others require a visit or a request; small fees are common.
When a plat changes
Lots near Carbon Cliff can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near East Moline, but coverage can be spotty out of town. A screenshot of the parcel near Rock Island with its ID keeps working without signal.
