Omaha and Gallatin County
Omaha is associated with Gallatin 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.
Omaha by land and water
The Census records 0.05 square miles of water within Omaha, or 0.3% of its total area. It is 1.3 percentage points lower than the 1.6% recorded for Gallatin County. This is geographic context; waterfront status and usable land must be checked at the parcel.
