Big River and San Bernardino County
Big River is associated with San Bernardino 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.
Big River by land and water
The Census records 0.52 square miles of water within Big River, or 4.6% of its total area. It is 4.4 percentage points higher than the 0.2% recorded for San Bernardino County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Big River CDP has 10.3 times the land area of nearby Bluewater CDP (1.05 square miles). These areas describe boundaries, not comparable property prices.
