      (4)   With respect to open space which is to be reserved for use solely by resident property owners, the developer shall prepare and file the following with the City Council and Plan Commission as companion documents with the proposed residential areas:
         (a)   Proposed articles of incorporation of a homeowner’s association or some comparable type of organization establishing equal common ownership of and criteria for maintenance of all common open space; and
         (b)   Proposed declaration of covenants and restrictions governing:
            1.   Property rights in the common properties;
            2.   Declaration of lands subject to such covenants, including provisions for expansion where expansion is possible;
            3.   Voting rights of property owners;
            4.   Requirements pertaining to mandatory membership in the homeowner’s association and criteria for assessing and collecting maintenance fees;

            8.   If, in the opinion of the appropriate city official, a public nuisance is created on any part of the aforementioned common open space, the city shall then place the developer, subdivider or homeowner’s association on notice by registered mail and specify corrective measures required. If, within ten days after said notice, no action has taken place, the city may exercise its option to take corrective measures and invoice the responsible party.
   (K)   Design standards. The following standards shall be used as a framework for evaluating a proposed RE District.
      (1)   Topography. The topography shall be preserved, wherever possible, in its natural state by minimizing grade changes and alterations. Building sites and street locations should conform to the extent possible to existing land contours.
      (2)   Street layout.
         (a)   The streets shall be curved, wherever possible, to provide gentle curvilinear street patterns. Streets shall be located, wherever possible, to preserve the natural elements of the site, as well as those of surrounding properties. Further, the number of new intersections with existing and proposed major or secondary arterials and collector/distributor streets shall be kept to a minimum.
         (b)   The use of cul-de-sacs to provide access to the residences is encouraged so as to provide privacy for the units, more variety in site planning, and views oriented away from neighbors’ yards and units.
      (3)   Preservation of landscape. The landscape shall be preserved in its natural state, insofar as practicable, by minimizing tree and soil removal so that the resulting development will be in keeping with the general appearance of neighboring developed areas and will not adversely affect the ecology of the area. Wherever the natural landscape is not preserved or no vegetation existed, mature landscape materials, emphasizing the use of evergreens, shall be installed in accordance with a plan approved by the Director of Parks, Forestry and Public Works.
      (4)   Relation of proposed building to environment and existing development. Proposed structures shall be related harmoniously to the terrain and to the existing structures that have visual relationship to the proposed structures.
      (5)   Utility services. Electric and telephone lines shall be underground. Any utility installations remaining above ground shall be located so as to have harmonious relation to neighboring properties and the site.
   (L)   Modifications. The City Council may approve modifications in connection with a particular development plan which are consistent with the purposes of this chapter.
