Darby and Union County
Darby 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.
Darby by land and water
The Census records 0.35 square miles of water within Darby, or 1.1% of its total area. That share is close to Union County’s 1.2%. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Darby township has 197.3 times the land area of nearby Unionville Center village (0.16 square miles). These areas describe boundaries, not comparable property prices.
