A.   Purpose and intent. The purpose of creating development standards for attached development dwellings is to ensure the development of communities that are appropriate to the hillside setting as well as preserving the look of a natural hillside to the greatest extent possible.  The various standards are designed to work together and result in a hillside community design that provides the ideal amount of private and common open space.  In addition to ideal amounts of open space, the standards will also ensure that structures will be built so as not to offset the visual scale and natural appearance of the hillsides.
   B.   Density.  Density limitations shall be determined as set forth in § 20.206.060.  Where attached housing is proposed, the overall permitted density of a development site shall determine the maximum number of units allowed, and all such attached units may be placed on a pad or pads restricted to a limited area of the development site, with the density calculation applicable to the site as a whole.  However, in compliance with the provisions of § 20.206.090, any remaining natural open space shall be deed restricted against further residential development and shall be permanently maintained as required by the provisions of this chapter.
   C.   Building setbacks.  Buildings shall be set back from pad edges as indicated in Table 20.206.180.C.

   D.   Building height.  Each proposed attached dwelling unit structure shall comply with the following height limits.
      1.   Height measurement.  The maximum allowable building height shall be measured as in compliance of §  20.206.170.F.1.
      2.   General height limit.  No structure or group of structures shall exceed a height of forty-five (45) feet.
      3.   Height of lowest floor level.  The vertical distance between the lowest point where the foundation meets grade and the lowest floor line of the structure shall not exceed six (6) feet.
   E.   Required common open space area.  Every attached development project shall be required to provide common open space areas accessible to all dwelling units within such development project and located on a pad.  The required area shall be as set forth in Table 20.206.180.E.  Such common open space area may consist of landscaped areas that can accommodate active use, common recreation facilities such as a swimming pool or sports court, or any combination of such improvements.  The minimum dimensions of such common open space area shall be twenty (20) feet by twenty (20) feet.  Such common open space shall be centrally located and easily accessible to all dwelling units within the development.  Landscaped slopes and natural open space areas shall not count toward the common open space requirement.

   F.   Private open space.  Private open space shall be provided as required by § 20.220.040.
   G.   Location of garages. Garage structures for attached developments are not required to be attached to the dwelling units they serve.  Common garage structures may be developed, provided parking is provided for each dwelling unit in compliance with the requirements of § 20.206.040.
