Finding a lot on the Atlantic GIS map
Parcel maps here are usually run by the county, not the town, so for this town the go-to is the, at least around Anita.Cass County Beacon site.
Where the parcel data lives
Your first stop is the Cass County Beacon site; it covers each assessed parcel from Lewis to Cumberland. If the land is near Lewis, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. In and around Marne, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and often a sale date.
A quick look at the area
Atlantic serves as the county seat, home to the main records offices. Smaller places on the map include Marne, Lewis, Wiota, and Cumberland, each with its own cluster of lots. About 13,130 people live in Cass County (Census estimate, 2023) on about 564 square miles. Cass County was formed in 1851, so old deeds can run back a long way.
Browser tips
When the map won't open around Cumberland, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
Where the recorded documents are
Before you sign anything, request the recorded deed through the County Recorder; the parcel line is a drawing of it, which applies near Cumberland as much as anywhere. Long-held tracts near Wiota can go back through several deeds, so a title company can sort it out if money is changing hands.
Limits of the parcel data
Acreage on the record is an assessed number; only a licensed surveyor establishes the real boundary on land around Wiota. With a lot near Anita, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Using it on a phone
