Weighing a property around North Pekin? A quick look at the East Peoria flood zone map shows whether it sits in a FEMA flood zone, and it costs nothing to check. This East Peoria guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Tazewell County ArcGIS parcel map.
Checking the East Peoria flood zone map step by step
The official source is FEMA's Flood Map Service Center: search an address around Pekin, and pick the FIRMette or map view. A tract near Creve Coeur without an address can still be found: pan from the closest town and click the spot.
The free map to start with
Your first stop is the Tazewell County ArcGIS parcel map; it includes each assessed parcel around Creve Coeur and North Pekin. Out toward Morton, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. In and around Creve Coeur, the record panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Offices that can help
Deeds, mortgages and recorded plats for land near Creve Coeur are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), sometimes only in person. Zoning, permits and septic questions near North Pekin go to planning, building or health offices, and the answer depends on jurisdiction.
East Peoria and the county around it
East Peoria is part of Tazewell County, Illinois, so its parcels are on the county's map. For a tract near Pekin, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the town limits near Morton often falls under county rules rather than the town's.
Next door to Tazewell County
Tazewell County meets Fulton County, Logan County, McLean County, Mason County, and Peoria County, all with their own assessor records. Acreage along the edge near Marquette Heights may be split across two assessors' files, so check the neighboring map before you assume the acreage. For a home near Marquette Heights, our state page lists every bordering county map across Illinois.
Questions to ask before you buy
Ask the seller for any Elevation Certificate on the property near Morton; getting a quote early keeps the budget honest.
Beyond the mapped zones
Small streams around Washington aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Pekin can limit building too; check the National Wetlands Inventory mapper for a first look.
Reading A, AE and X
An AE label carries a published BFE, while plain Zone A does not; that elevation drives building rules near Washington. For a tract near Marquette Heights, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the Tazewell County ArcGIS parcel map for the outline of the tract near Creve Coeur.
Field tips
Most viewers work in a phone browser, handy when you're parked on a road near Marquette Heights, though signal can drop in rural spots. A saved image of the lot near Creve Coeur and its lines helps when you meet an owner or agent.
Lenders and permits
With a lot near Creve Coeur, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. New construction in a floodplain near Creve Coeur usually means extra permit review; call the permitting office before you plan.
Before you lean on the lines
Listed acreage is an assessed number; just a licensed surveyor can set the real corners on land around North Pekin. For land near Washington, owner names and values update on a schedule, so a deed recorded last month might lag behind.
How land is described here
Illinois is laid out under the Public Land Survey System, so deeds around Morton reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Pekin can be irregular. Keep the legal description for land near Pekin when you talk to a surveyor.

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.
