Before you buy or build near Shawnee National Forest, check the Gallatin County flood zone map: the zone on that map shapes insurance, permits and resale. Covered here for Gallatin County: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Gallatin County WTH GIS map.
The Gallatin County flood zone map: start here
For a home near New Haven, flood zones come from FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. A tract near Old Shawneetown without an address can still be found: search the nearest road then click the parcel area.
Where the parcel data lives
Your first stop is the Gallatin County WTH GIS map; it includes every tax parcel around Lawler and New Haven. For acreage around Junction, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a home near Elba, save the parcel ID before closing the panel; every records desk in the county asks for it first.
Zones on the Gallatin County flood zone map
For a home near Lawler, A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a parcel near Lawler, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements for land near Shawnee National Forest are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Long-held tracts near New Haven can sit on several deeds, and a title company can sort it out before a purchase.
Use the county map alongside FEMA

A word on accuracy
Acreage on the record is an assessed number; just a licensed surveyor can set the real corners on land around Elba. Records update in batches, so a recent sale near Elba can take weeks to appear.
Reading the legal description
Illinois follows the Public Land Survey System, so rural legal descriptions near Wabash River cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Ohio River can be irregular. Write down the legal description for the tract near Lawler when you talk to a surveyor.
Insurance, lenders and building
For property near Omaha, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Elba in a mapped zone can trigger elevation rules; check with the county or town building office early.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Lawler, so load it before you lose signal. A printout of the tract near Shawneetown is a good backup.
Low spots and local drainage
Low-lying fields near Wabash River aren't always studied in detail, so walk the land after rain. Wetlands near Old Shawneetown can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
