Ottawa and Waukesha County
Ottawa is associated with Waukesha 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.
Ottawa by land and water
The Census records 1.17 square miles of water within Ottawa, or 3.4% of its total area. It is 1.9 percentage points lower than the 5.3% recorded for Waukesha County. This is geographic context; waterfront status and usable land must be checked at the parcel.
