Acreage and vacant lot search
Here's a simple routine for finding open ground in Kewaunee County using the parcel map:
- Pan the Kewaunee County map with imagery turned on and flag any tract that looks empty.
- For each tract near Carlton, note the parcel ID, the owner and where the tax bill is mailed.
- Assessed values lag the market, but comparing tracts near Dyckesville still shows which ones the county rates higher.

What the Kewaunee County GIS map shows about lot lines
A Kewaunee County GIS map is built for assessment, not construction. In Kewaunee County, as in most places, the lines are a best fit of old deed calls onto modern aerial photos. Rural Kewaunee County land sits on the federal survey grid: a deed might call out a quarter of a numbered section in a given township and range. A survey is the only document that settles where a Kewaunee County boundary actually runs.
Before you rely on the data
Splits and sales near Dyckesville can take weeks or months to show up on the parcel layer. The acreage on a Luxemburg record is what the tax roll uses, and a survey can come out different.
