Ahead of any purchase around Tallula, check the Menard County flood zone map: a mapped flood zone changes insurance, building rules and resale. This Menard County guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Menard County Beacon site.
Checking the Menard County flood zone map step by step
For parcel-by-parcel detail, use the National Flood Hazard Layer viewer, where zone shading sits over a photo base, which applies near Atterberry as much as anywhere. A tract near Tallula without an address can still be found: zoom in from the nearest road and click inside the land.
Getting to the right map
Go first to the Menard County Beacon site; it covers every tax parcel from Atterberry to Greenview. For a parcel near Bobtown, type a street address, an owner's name or a parcel number, and the matching parcel lights up. With a lot near Athens, the parcel card usually lists the owner of record, assessed acreage, the parcel number and often a sale date.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Bobtown, but coverage can be spotty out of town. A screenshot of the parcel near Greenview with its ID is a good backup.
Reading the legal description
Illinois is laid out under the Public Land Survey System, so rural legal descriptions near Athens cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Fancy Prairie can be irregular. Copy the legal description from the record for the parcel near Bobtown before you request a deed or survey.
Recorded documents worth pulling
For anything that matters, get the recorded deed from the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Atterberry only summarizes it. Long-held tracts near Athens can trace back through many deeds, so a title company is worth hiring before a purchase.
A word on accuracy
On ground around Hubly, the acreage figure is an estimate; just a licensed surveyor can set the real boundary on the ground. For acreage around Tallula, records update in batches, so a deed recorded last month may not show yet.
A short flood checklist
Closer to Tallula, request about past flood claims before closing; an insurance quote early avoids surprises.
Reading A, AE and X
For a parcel near Athens, zones beginning with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a parcel near Atterberry, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X is minimal risk.
Low spots and local drainage
Creeks and ditches near Hubly may not have detailed mapping, so walk the land after rain. Marshy spots near Tallula can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Places you'll see on the map
Petersburg is the county seat, which is where the courthouse records live. Smaller places on the map include Athens, Greenview, Oakford, and Tallula, each with its own cluster of lots. Around 11,954 people call Menard County home (Census estimate, 2023) on about 314 square miles. The county dates to 1839, which matters when you trace an old farm's title, at least around Petersburg.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the Menard County Beacon site to see exactly which lot near Greenview you're looking at.
When a parcel crosses a boundary
The county meets Cass County, Logan County, Mason County, and Sangamon County, all with their own assessor records, especially near Bobtown. Ground near Lake Petersburg that runs to the line can be split across two assessors' files, so check the adjacent map before you assume the acreage. For property near Tallula, the Platbookmapper state page lists every bordering county map for Illinois.
Insurance, lenders and building
For a structure inside an A or V zone and the loan is federally backed or regulated, the lender will require flood insurance where the community participates in the National Flood Insurance Program, which applies near Atterberry as much as anywhere. Building or adding on near Petersburg in a mapped zone can trigger elevation rules; ask the local floodplain administrator early.

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.
