An R-2 district is intended to allow for a moderate density of land use that is greater than is permitted in an R-1 district but less than is permitted in an R-3 district, where suitable facilities such as streets, water, sewer and storm drainage are available. An R-2 district provides a transition between a higher density residential district in order to preserve the primarily residential character of existing lower density residential areas. (Ord. 710 § 9, 1996; Ord. 573 § 2, 1990).
