Ahead of any purchase around Deer Creek, pull up the Morton flood map: FEMA's zone label affects insurance, building rules and resale. This Morton guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the county ArcGIS parcel map for land near Deer Creek.
Getting started with the Morton flood map
Start with FEMA's Flood Map Service Center: type an address near Creve Coeur, and choose the dynamic map. Vacant ground around Marquette Heights can still be found: search the nearest road and click inside the land.
The viewer Tazewell County publishes
Go first to the Tazewell County ArcGIS parcel map; it covers each assessed parcel around East Peoria and Deer Creek. Around Marquette Heights, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. With a lot near Tremont, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and often a sale date.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near East Peoria, but coverage can be spotty out of town. A screenshot of the parcel near Tremont with its ID is a good backup.
Morton and the county around it
Morton sits in Tazewell County, Illinois, which means parcel data comes from the county. On ground around Marquette Heights, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Acreage past the town limits toward Creve Coeur usually follows county rules, not municipal ones.

Tazewell County touches Fulton County, Logan County, McLean County, Mason County, and Peoria County, all with their own assessor records. A tract near the line by Deer Creek can be split in two county records, so look at the neighboring map too. For land near East Peoria, our state page lists every bordering county map for Illinois.
Water near Marquette Heights
Small streams around Tremont may not have detailed mapping, so look for water marks and debris lines. Wetlands near Washington can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Questions to ask before you buy
Ask the seller about past flood claims for the house near Deer Creek; getting a quote early keeps the budget honest.
A quick look at the area
Pekin is the county seat, which is where the courthouse records live. Other places on the map include East Peoria, Tremont, Washington, and Creve Coeur, where town lots give way to larger tracts. About 129,541 people call Tazewell County home (Census estimate, 2023) on some 646 square miles. The county was formed in 1827, and some chains of title near Tremont are long.
Reading the legal description
Illinois uses the Public Land Survey System, so rural legal descriptions near Tremont cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near East Peoria vary in size. Copy the legal description from the record for the parcel near Tremont before you request a deed or survey.
Before you lean on the lines
Listed acreage is an estimate; just a licensed surveyor sets the real boundary for a parcel near Tremont. With a lot near East Peoria, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Zones on the Morton flood map
Out toward East Peoria, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. Closer to East Peoria, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so pair it with the Tazewell County ArcGIS parcel map for the outline of the tract near East Peoria.
Lenders and permits
Out toward Washington, get the Elevation Certificate if one exists: it can change the insurance price a lot. Remodeling a house in a zone near Marquette Heights can trigger elevation rules; call the permitting office early.
Questions about the Morton flood map
When is flood insurance required near East Peoria?
Lenders generally require it for buildings near East Peoria in a Special Flood Hazard Area when the loan is federally regulated or insured; elsewhere it's optional.
Is AE a high-risk flood zone in Morton?

It depends, but a flood layer may appear in the Tazewell County ArcGIS parcel map layer list, though it can lag behind FEMA's current panels.
Does the parcel map work on a phone near Creve Coeur?
The map near Washington usually works on a phone; load it before you lose coverage near Tremont.
