The purpose of the R-2, Multiple Family Residential District is to promote a harmonious mixture of housing options and related educational, cultural, and religious land uses in a primarily residential environment. Various types and sizes of medium and high density residential units shall be provided at planned locations in the community to meet the needs of the different age and family groups. This district shall generally be located along major streets and shall be served by public water and sewerage systems and other appropriate urban facilities and services. Uses in this district shall be subject to appropriate design, density, and development standards (including, but not limited to density, bulk, setback and separation, adequate light and air, privacy and recreation areas) that are intended to prevent congestion on public streets, reduce hazards to life and property, and provide adequate recreation areas and basic amenities. There is no intent to promote by these regulations a district of lower quality or desirability than any other residential district, although a higher density of population and a greater variety of dwelling types are permitted herein.
