These single family residential areas include existing neighborhoods and subdivisions, and include vacant or agricultural land areas where future development at a base density of 3 to 4 units per acre may occur.  As a standard single family residential subdivision, R-1-10 zoning with a minimum lot size of 10,000 s.f. may apply, or R-1-8 zoning with a minimum lot size of 8,000 s.f. may also apply. 

The base density may be increased through use of the PRUD overlay ordinance to provide neighborhoods with housing and lot size variety, clustered around common open space3 amenity areas.  Flexibility in lot size, setbacks and housing type allows for the provision of common open space3 areas.  The cost of maintaining open space is shared by more homeowners through a density bonus that requires high quality building materials and superior community design (see Chapter 6. Residential Neighborhoods with Variety and Amenities).
