Grand Island and Alger County
Grand Island is associated with Alger 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.
Grand Island by land and water
The Census records 26.6 square miles of water within Grand Island, or 54.2% of its total area. It is 27.7 percentage points lower than the 81.9% recorded for Alger County. This is geographic context; waterfront status and usable land must be checked at the parcel.
