B. The following land areas shall not be included in the calculation of required open space under the terms of this section:
(1) The area within any public street right-of-way and within any private street easement.
(2) Any easement for overhead utility lines.

D. If the PUD includes a body of water, the PUD ordinance may require that a portion of the required open space abut the body of water.
E. A portion of the required open space may be required to be located along the public street frontage of the PUD. The PUD ordinance may determine the required depth of this portion of required open space. The open space shall be preserved in its natural condition or be landscaped such as to reduce the view of dwellings from the adjacent streets and to preserve and enhance the rural view.
F. Required open space areas shall be configured so that the open space is reasonably accessible to and usable by residents of the PUD.
