Transitional residential areas may include attached or detached single family housing with a moderate density ranging between 6 and 12 units per acre, townhomes, mansion homes, Live/Work2 townhomes, detached single family, twin homes or patio homes.  These housing types are intended to establish a buffer and transition between intensive land uses or street conditions and lower density single family residential areas.  Transitional residential uses should provide open space amenity areas, either as common or limited common areas for the use and enjoyment of residents and their guests.  To support a walkable, pedestrian-friendly design format, units should front towards a street or open space green, and garage or parking areas located and accessed primarily to the rear.
