THE UNION LAND BRIEF
Land in the
Blufflands and Coulees setting.
Union town has 34.8 square miles of land in Pierce County. Its Census reference point is in Blufflands and Coulees, within Driftless Area.
Deeply cut valleys divide a bedrock plateau with windblown soil on many uplands. Glaciers had less influence here than in neighboring regions, leaving a distinctly hilly landscape.

Union and Pierce County
Union is associated with Pierce County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Union by land and water
The Census records 0.2 square miles of water within Union, or 0.6% of its total area. It is 2.6 percentage points lower than the 3.2% recorded for Pierce County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Union town has 33.4 times the land area of nearby Plum City village (1.04 square miles). These areas describe boundaries, not comparable property prices.
