Jarvis and Madison County
Jarvis is associated with Madison 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.
Jarvis by land and water
The Census records 0.5 square miles of water within Jarvis, or 1.4% of its total area. It is 1.9 percentage points lower than the 3.3% recorded for Madison County. This is geographic context; waterfront status and usable land must be checked at the parcel.
