Ahead of any purchase around Carbon Cliff, look at the East Moline flood zone map: the zone on that map shapes insurance, permits and resale. This East Moline guide covers: the free FEMA tools, what each zone label means, when insurance is required and what a LOMA is.
The East Moline flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: search an address around Rapids City, and pick the FIRMette or map view. Rural land near Carbon Cliff with no street number is still easy to locate: zoom in from Interstate 74 and click inside the land.
Getting to the right map
Begin with the Rock Island County parcel viewer; it covers every tax parcel in the county, Carbon Cliff included. Closer to Hampton, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a home near Silvis, the record panel usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
What to request from a seller
Ask the seller about past flood claims for the house near Hampton; an insurance quote early keeps the budget honest.
Legal descriptions in Illinois
Illinois follows the Public Land Survey System, which means a tract near Port Byron is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Hampton odd-sized. Write down the legal description for the tract near Hampton when you talk to a surveyor.
East Moline, IL: the basics
East Moline sits in Rock Island County, Illinois, so its parcels are on the county's map. For a tract near Moline, City or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Lots just outside the city limits toward Rapids City generally answers to county rules rather than the town's.
Where the recorded documents are
The map is an index, not the title: recorded deeds, plats and easements covering ground around Hampton are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Long-held tracts near Carbon Cliff may sit on many deeds, and a title company can sort it out if money is changing hands.
Zones on the East Moline flood zone map
Zone AE carries a published BFE, which plain A zones lack; surveyors near Rapids City use that number. If the land is near Hampton, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Moline, but coverage can be spotty out of town. A saved image of the lot near Rapids City and its lines keeps working without signal.
Parcel lines plus flood zones
When the zone clips a corner of a lot near Silvis, the structure's footprint is the key question.
What the map can't tell you
The acreage figure is a tax-roll number; only a licensed surveyor sets the real boundary on land around Port Byron. For a home near Silvis, records update in batches, so a deed recorded last month might lag behind.
Beyond the mapped zones
Small streams around Carbon Cliff may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Port Byron can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Money questions tied to the zone
For property near Silvis, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Remodeling a house in a zone near Moline can trigger elevation rules; call the permitting office before you plan.
Land on the county line
Rock Island County touches Henry County, Mercer County, Whiteside County, Clinton County, IA, and Louisa County, IA, all with their own assessor records. Acreage along the edge near Port Byron may be split in two county records, so look at the neighboring map before you assume the acreage. Out toward Carbon Cliff, our state page lists each neighboring county map for Illinois.
