Fairfield and Washington County
Fairfield is associated with Washington 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.
Fairfield by land and water
The Census records 0.04 square miles of water within Fairfield, or 0.2% of its total area. It is 1.1 percentage points lower than the 1.2% recorded for Washington County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Fairfield township has 64.1 times the land area of nearby Vincent CDP (0.38 square miles). These areas describe boundaries, not comparable property prices.
