Union and Washington County
Union is associated with Washington 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 0.08 square miles of water within Union, or 0.2% of its total area. It is 0.2 percentage points lower than the 0.4% recorded for Washington County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Union township has 160 times the land area of nearby Mahaska city (0.22 square miles). These areas describe boundaries, not comparable property prices.
