Before an offer near Chestnut, pull up the Logan County flood zone map: FEMA's zone label affects insurance, building rules and resale. In this Logan County guide: locating a parcel on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Where the Logan County flood zone map lives
For parcel-by-parcel detail, open the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, for land near Emden included. Rural land near Chestnut with no street number is still easy to locate: zoom in from Interstate 155 and click inside the land.
Where the parcel data lives
Go first to the Logan County ArcGIS parcel map; it covers every assessed parcel from Emden to Hartsburg. Without an address in hand, pan along Interstate 155 and select the outline. For land near Mount Pulaski, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Zones on the Logan County flood zone map
Near Burton View, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a tract near Atlanta, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Legal descriptions in Illinois
Illinois follows the Public Land Survey System, so deeds around Bakerville reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Burton View vary in size. Write down the legal description for the tract near Atlanta when you talk to a surveyor.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the Logan County ArcGIS parcel map too for the outline of the tract near Cornland.
A short flood checklist
For a tract near Hartsburg, request about past flood claims before closing; getting a quote early avoids surprises.
Getting answers from the right desk
If the acreage or value on a parcel near Lincoln looks off are handled by the Supervisor of Assessments, working with township assessors, which maintains the tax roll. Building or septic questions for a lot near Emden are for the local planning and health departments, town or county, depending on location.
Insurance, lenders and building
For a structure inside an A or V zone and a federally regulated lender is involved, the lender will require flood insurance in communities in the NFIP, and that holds around Elkhart too. Building or adding on near Hartsburg in a mapped zone usually means extra permit review; ask the local floodplain administrator before you plan.
Places you'll see on the map
Lincoln is the county seat, home to the main records offices. You'll also find Atlanta, Mount Pulaski, Broadwell, and Elkhart, each with its own cluster of lots. About 27,590 people call Logan County home (Census Bureau estimate, 2023) spread over roughly 618 square miles. Logan County was formed in 1839, and some chains of title near Broadwell are long.
The paper trail behind a parcel
For anything that matters, request 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 Mount Pulaski or elsewhere in the county. In and around Atlanta, use the document number shown in the record panel and the lookup takes minutes.
Water near Atlanta
Low-lying fields near Hartsburg aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Atlanta can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Beason, so load it before you lose signal. A screenshot of the parcel near Broadwell with its ID is a good backup.
Limits of the parcel data
If you're looking near Bakerville, acreage on the record is an assessed number; just a licensed surveyor sets the real boundary on the ground. For land near Bakerville, records update in batches, so a deed recorded last month may not show yet.
Questions about the Logan County flood zone map
How do I get a property removed from a flood zone around Lincoln?
Short answer: you can ask FEMA for a LOMA if surveyed elevations show the building near Burton View is above the BFE; it starts with an elevation survey.
How can I tell if a house near Mount Pulaski is in a flood zone?
For most people, search the address near Hartsburg on FEMA's Flood Map Service Center; no account is needed.
What is a base flood elevation for land near Emden?
Short answer: a BFE near Mount Pulaski tells builders how high the lowest floor should be; local rules may require building above it.
Can a property in Zone X near Beason flood?
Good question; X zones around Hartsburg are lower risk, not no risk, and floods still happen outside high-risk zones.
Is the parcel map a survey near Lincoln?
In and around Burton View, parcel lines are tax drawings, not surveys; a survey sets the real corners

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.
