Rio Rico and Santa Cruz County
Rio Rico is associated with Santa Cruz 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.
Rio Rico by land and water
The Census records 0.19 square miles of water within Rio Rico, or 0.3% of its total area. It is 0.2 percentage points higher than the 0.1% recorded for Santa Cruz County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Rio Rico CDP has 33 times the land area of nearby Tumacacori-Carmen CDP (1.91 square miles). These areas describe boundaries, not comparable property prices.
