Westfield and Union County
Westfield is associated with Union 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.
Westfield by land and water
The Census records 0.02 square miles of water within Westfield, or 0.3% of its total area. It is 2.2 percentage points lower than the 2.5% recorded for Union County. This is geographic context; waterfront status and usable land must be checked at the parcel.
