This district provides for a diversity of single-family and low-density multifamily dwelling units at three (3) to eight (8) units per acre (maximum). It establishes a range of lifestyles from detached to attached units to accommodate the changing patterns of growth in the County. In order to provide for such densities, adequate buffering, access, recreation and open space must be supplied either on each parcel or in common, reserved areas of public access. An atmosphere of community and neighborhood must be maintained that blends in with the existing character of the surrounding area.
