Rochester and Beaver County
Rochester is associated with Beaver 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.

The Census records 0.07 square miles of water within Rochester, or 1.7% of its total area. It is 0.4 percentage points lower than the 2.1% recorded for Beaver County. This is geographic context; waterfront status and usable land must be checked at the parcel.
