Before an offer near Schaeferville, check the Tazewell County flood zone map: FEMA's zone label affects insurance, permits and resale. This Tazewell County guide covers: finding the address on FEMA's map, reading the zone codes, and confirming the outline on the county map.
The Tazewell County flood zone map: start here
On ground around Creve Coeur, start with FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Rural land near Pekin with no street number is still easy to locate: zoom in from Interstate 74 then click the parcel area.
The viewer Tazewell County publishes
Go first to the Tazewell County ArcGIS parcel map; it includes every tax parcel in the county, Schaeferville included. For a tract near Creve Coeur, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near East Peoria, write down the parcel ID while you have it open; every office in the county will want it.
Decoding the flood zone labels
On ground around Marquette Heights, any A or V zone mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. For a home near Delavan, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so open the Tazewell County ArcGIS parcel map next to see exactly which lot near Washington you're looking at.
Limits of the parcel data
On ground around Delavan, listed acreage is an assessed number; just a licensed surveyor can set the real lines on the ground. In and around Heritage Lake, owner names and values update on a schedule, so a deed recorded last month may not show yet.
How land is described here
Illinois uses the Public Land Survey System, so deeds around Heritage Lake reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Creve Coeur can be irregular. Keep the legal description for land near Delavan when you talk to a surveyor.
Getting your bearings
Pekin holds the county offices, home to the main records offices. You'll also find Delavan, East Peoria, Marquette Heights, and Washington, where town lots give way to larger tracts. About 129,541 people live in Tazewell County (Census estimate, 2023) spread over about 646 square miles. Tazewell County dates to 1827, so old deeds can run back a long way.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Schaeferville, but coverage can be spotty out of town. A printout of the tract near Pekin is a good backup.
Lenders and permits
If you're looking near Schaeferville, an Elevation Certificate from a surveyor helps: it records the building's elevation against the base flood. Building or adding on near Deer Creek in a mapped zone can trigger elevation rules; call the permitting office before you plan.
The paper trail behind a parcel
Before you sign anything, get the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the viewer just points to it, whether the land is near Heritage Lake or elsewhere in the county. For property near Creve Coeur, use the document number from the tax record to skip a name search.
Water near Heritage Lake
Small streams around Marquette Heights aren't always studied in detail, so ask neighbors about past flooding. Wetlands near Deer Creek can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Offices that can help
Deeds, mortgages and recorded plats for land near Heritage Lake sit in the index kept by the county Recorder of Deeds (in many counties the County Clerk and Recorder), sometimes only in person. Building or septic questions for a lot near Groveland need the planning or permitting office, and the answer depends on jurisdiction.
A short flood checklist
With a lot near East Peoria, ask the seller about past flood claims before closing; an insurance quote early keeps the budget honest.
