The purpose of the R-1 zone is to accommodate low-density residential uses composed of single-unit detached residences and duplex dwellings on corner lots. This zone may also include recreational, religious, and educational facilities as the basic elements of a balanced neighborhood. These areas should be clearly defined and without encroachment by uses not performing a neighborhood function. (Ord. 2013-0020 § 1; Ord. 2013-0007 § 1)
