Weighing a property around Washington? Checking the Creve Coeur flood zone map reveals whether it sits in a FEMA flood zone, and the lookup is free. Covered here for Creve Coeur: locating a parcel on FEMA's map, decoding A, AE and X, and matching it with the county parcel viewer.
Where the Creve Coeur flood zone map lives
The official source is FEMA's Flood Map Service Center: type an address near East Peoria, and pick the FIRMette or map view. A tract near Morton without an address can still be found: pan from the closest town then click the parcel area.
Getting to the right map
Begin with the Tazewell County ArcGIS parcel map; it maps each assessed parcel around Pekin and Morton. For a tract near Pekin, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near East Peoria, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around East Peoria sit with the county Recorder of Deeds (in many counties the County Clerk and Recorder). For land near East Peoria, use the book and page from the tax record so staff can find the deed fast.
Creve Coeur and the county around it
Creve Coeur lies within Tazewell County, Illinois, so its parcels are on the county's map. Closer to East Peoria, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Acreage past the town limits near Marquette Heights often answers to county rules, not municipal ones.
Zones on the Creve Coeur flood zone map
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; that elevation drives building rules near Pekin. If you're looking near Marquette Heights, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
A word on accuracy
Tax maps are drawn for assessment, not surveyed, so the edge of a yard near Washington can sit a few yards off the line on screen. In and around Marquette Heights, owner names and values update on a schedule, so a deed recorded last month might lag behind.
A short flood checklist
Ask the seller whether the home has flooded on the property near North Pekin; an insurance quote early avoids surprises.
Which office to call
Recorded documents for a parcel near Washington are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), often with an online index. Building or septic questions for a lot near Marquette Heights need the planning or permitting office, and the answer depends on jurisdiction.
Sections, lots and bearings
Illinois is laid out under the Public Land Survey System, so rural legal descriptions near Pekin cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near North Pekin odd-sized. Write down the legal description for the tract near Washington for any title or survey request.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Tazewell County ArcGIS parcel map to confirm you have the right parcel near North Pekin.
Beyond the mapped zones
Creeks and ditches near Marquette Heights may not have detailed mapping, so look for water marks and debris lines. Marshy spots near Marquette Heights can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required where the community participates in the National Flood Insurance Program, whether the land is near East Peoria or elsewhere in the county. Remodeling a house in a zone near East Peoria usually means extra permit review; ask the local floodplain administrator early.
Neighboring parcel maps
With a lot near Marquette Heights, Tazewell County borders Fulton County, Logan County, McLean County, Mason County, and Peoria County; every one of them runs a separate parcel map. A tract near the line by Morton can show up in two county records, so check the adjacent map as well. For acreage around Pekin, our state page lists every bordering county map across Illinois.
Frequently asked
Can a flood zone near Pekin change?
Usually, a new study can move a zone line near Washington, so look at the panel date.
When is flood insurance required for land near East Peoria?
In most cases, for a building near Marquette Heights in an A or V zone with a federally backed or regulated mortgage, it's generally required; outside those zones it's your call.
Is there a flood layer on the parcel viewer near Marquette Heights?
Good question; a flood layer may appear in the Tazewell County ArcGIS parcel map layer list, but FEMA's own map is the official source.

It depends, but shaded X is moderate risk and unshaded X is minimal risk; many owners near Morton buy coverage anyway.
Does the parcel map work on a phone around Morton?

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.
