Denning and Ulster County
Denning is associated with Ulster 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.
Denning by land and water
The Census records 0.1 square miles of water within Denning, or 0.1% of its total area. It is 3.1 percentage points lower than the 3.1% recorded for Ulster County. This is geographic context; waterfront status and usable land must be checked at the parcel.
