Armstrong and Indiana County
Armstrong is associated with Indiana 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.
Armstrong by land and water
The Census records 0.15 square miles of water within Armstrong, or 0.4% of its total area. It is 0.5 percentage points lower than the 0.8% recorded for Indiana County. This is geographic context; waterfront status and usable land must be checked at the parcel.
