Hawthorne and Passaic County
Hawthorne is associated with Passaic 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.
Hawthorne by land and water
The Census records 0.03 square miles of water within Hawthorne, or 0.9% of its total area. It is 5.3 percentage points lower than the 6.2% recorded for Passaic County. This is geographic context; waterfront status and usable land must be checked at the parcel.
