South River and San Juan County
South River is associated with San Juan 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.
South River by land and water
The Census records 0.23 square miles of water within South River, or 2.7% of its total area. It is 2.3 percentage points higher than the 0.4% recorded for San Juan County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, South River CDP has 1.7 times the land area of nearby Flora Vista CDP (4.95 square miles). These areas describe boundaries, not comparable property prices.
