Getting started with the East Moline GIS map
In most places the county maintains the parcel layer, which makes the Rock Island County parcel viewer the main source for lots in East Moline.
The viewer Rock Island County publishes
Your first stop is the Rock Island County parcel viewer; it covers each tax parcel in the county, Port Byron included. For acreage around 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 Hampton, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Troubleshooting the viewer
When the map won't open around Port Byron, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
East Moline and the county around it
East Moline lies within Rock Island County, Illinois, which means parcel data comes from the county. For acreage around Rapids City, City or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the city limits toward Silvis often answers to county rules rather than the town's.
A word on accuracy
Acreage on the record is an estimate; only a licensed surveyor can set the real boundary for a parcel near Silvis. For acreage around Carbon Cliff, records update in batches, so a deed recorded last month might lag behind.
Getting answers from the right desk
If the acreage or value on a parcel near Silvis looks off belong with the Supervisor of Assessments, working with township assessors, which maintains the tax roll. Questions about what you can build around Rapids City go to planning, building or health offices, and the answer depends on jurisdiction.
Keeping a record
Save a screenshot of the lot near Carbon Cliff and its record panel, which helps later when you ask the assessor or a title company.
Searching the map
Acreage around Hampton might not have a street number, which means panning to it and clicking. For a home near Port Byron, searching by parcel number never misses, and it's printed on tax bills.
When a parcel crosses a boundary
Rock Island County touches Henry County, Mercer County, Whiteside County, Clinton County, IA, and Louisa County, IA; every one of them runs a separate parcel map. Ground near Silvis that runs to the line can show up in two county records, so check the neighboring map too. Closer to Moline, our state page lists every bordering county map across Illinois.
Getting your bearings
Rock Island is the county seat, where most land records are kept. Smaller places on the map include Carbon Cliff, Silvis, Hampton, and Rapids City. Roughly 141,236 people live in Rock Island County (Census Bureau estimate, 2023) on some 427 square miles. Rock Island County was organized in 1831, and some chains of title near Moline are long. Places such as Upper Mississippi River National Wildlife and Fish Refuge are easy to spot when you zoom out from Hampton.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Moline, though signal can drop in rural spots. A screenshot of the parcel near Rapids City with its ID keeps working without signal.
Recorded documents worth pulling
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 Carbon Cliff only summarizes it. For a parcel near Moline, have ready the instrument number shown in the record panel and the lookup takes minutes.
Layers worth turning on
Toggling imagery near Hampton helps you see where buildings sit inside the lines.
Inside the parcel card
