(K) Design standards. The following standards shall be used as a framework for evaluating a proposed ROS 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 pattern. 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.
(c) The property within the ROS Single-Family Residence and Open Space District shall be developed in a manner consistent with its rural nature. The roadway and drainage systems therein may be developed with design appropriate to a county lane but shall meet the engineering standards of the city. An adequate pedestrian circulation system appropriately lighted shall be provided and the drainage system may incorporate materials other than concrete curbs and gutters.
(d) Principal through-streets shall be developed in accordance with the standards of the city and shall have a pavement width of not less than 20 feet. Secondary streets shall have a pavement width of not less than 16 feet. Streets serving six or fewer dwelling units shall have a pavement width of not less than 14 feet.
(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 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 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.
