THE WILMINGTON LAND BRIEF
Land in the
Rochester/Paleozoic Plateau Upland setting.
Wilmington township has 35.9 square miles of land in Houston County. Its Census reference point is in Rochester/Paleozoic Plateau Upland, 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.

Wilmington and Houston County
Wilmington is associated with Houston 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.
Wilmington by land and water
The Census records 0.08 square miles of water within Wilmington, or 0.2% of its total area. It is 2.7 percentage points lower than the 2.9% recorded for Houston County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Wilmington township has 36.1 times the land area of nearby Spring Grove city (0.99 square miles). These areas describe boundaries, not comparable property prices.
