Sonora and Hancock County
Sonora is associated with Hancock 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.
Sonora by land and water
The Census records 1.73 square miles of water within Sonora, or 4.6% of its total area. It is 2.1 percentage points higher than the 2.5% recorded for Hancock County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Sonora township has 10.6 times the land area of nearby Nauvoo city (3.39 square miles). These areas describe boundaries, not comparable property prices.
