Weighing a property around Whitewater? The Walworth County flood zone map tells you whether the lot falls inside a mapped floodplain, and the lookup is free. In this Walworth County guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Walworth County parcel viewer.
Checking the Walworth County flood zone map step by step
For a more interactive look, use the National Flood Hazard Layer viewer, where zone shading sits over a photo base, and that holds around Big Foot Prairie too. Vacant ground around Allen's Grove can still be found: zoom in from Interstate 43 and click inside the land.
Getting to the right map
Go first to the Walworth County parcel viewer; it maps every tax parcel in the county, Burlington included. On ground around Big Foot Prairie, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Lake Ivanhoe, copy the parcel ID while you have it open; each clerk in the county uses it to find the file.
How land is described here
Wisconsin is laid out under the Public Land Survey System, so deeds around Burlington reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Delavan Lake vary in size. Copy the legal description from the record for the parcel near Whitewater when you talk to a surveyor.
Questions to ask before you buy
If the land is near Elkhorn, request about past flood claims before closing; getting a quote early avoids surprises.
Water near Bloomfield
Low-lying fields near Delavan aren't always studied in detail, so look for water marks and debris lines. Wet ground around Lake Ivanhoe is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Reading A, AE and X
An AE label includes a base flood elevation (BFE), while plain Zone A does not; builders around Big Foot Prairie design to it. For property near Lake Geneva, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Before you lean on the lines
Listed acreage is an estimate; only a licensed surveyor can set the real lines on land around Delavan Lake. For acreage around Lake Geneva, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so check the Walworth County parcel viewer too for the outline of the tract near Lake Geneva.
Getting answers from the right desk
Questions about value or the owner field for land near Burlington belong with the county real property listing office, which maintains the tax roll. Zoning, permits and septic questions near Whitewater need the planning or permitting office, depending on whether the land is inside town limits.
When a parcel crosses a boundary
Walworth County touches Boone County, IL, McHenry County, IL, Jefferson County, Kenosha County, and Racine County, and each of those keeps its own parcel map. Acreage along the edge near Allen's Grove may show up across two assessors' files, so open the adjacent map too. Near Darien, the Platbookmapper state page lists every bordering county map for Wisconsin.
What a flood zone means for a buyer
On ground around Delavan Lake, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Building or adding on near Lake Ivanhoe in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Allen's Grove, so load it before you lose signal. A screenshot of the parcel near Lake Geneva with its ID is a good backup.
The paper trail behind a parcel
When the details count, request the recorded deed through the Register of Deeds; the viewer just points to it, whether the land is near Whitewater or elsewhere in the county. Older tracts around Allen's Grove can sit on a long string of deeds, so a title company can sort it out before a purchase.
Quick answers
What does Zone X mean near Delavan?
In most cases, Zone X near Delavan Lake means moderate (shaded) or minimal (unshaded) mapped risk; many owners near Big Foot Prairie buy coverage anyway.
What is a base flood elevation for land near Burlington?
In and around Big Foot Prairie, the base flood elevation is the water level expected in the 1% annual chance flood; local rules may require building above it.
Is there a flood layer on the parcel viewer near Big Foot Prairie?
It depends, but a flood layer may appear in the Walworth County parcel viewer layer list, though it can lag behind FEMA's current panels.
What is a LOMA around Burlington?
For property near Delavan Lake, a Letter of Map Amendment (LOMA) from FEMA can remove a structure on naturally high ground; a surveyor's elevation data supports it.
What's a legal description around Como?
For property near Elkhorn, Deeds use lot and block, metes and bounds or survey descriptions, and the parcel record often summarizes it.

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.
