In order to assure adequate levels of light, air and density of development, to maintain and enhance locally recognized values of community appearance, and to promote the safe and efficient circulation of pedestrian and vehicular traffic, the standards in this chapter are found to be necessary for the preservation of the community health, safety and general welfare. In addition to the land use and development standards in Sections 18.104.071 through 18.104.076, the following shall apply to the residential development areas in the Summit Specific Plan.
.010 Landscaped Area Adjacent to Arterial Highways and Expressways. The minimum landscaped area adjacent to arterial highways and expressways (such as Oak Hills Drive, Serrano Avenue and Weir Canyon Road), including sloped areas, shall be seven (7) feet for down-slope conditions and fourteen (14) feet for up-slope conditions, varying between conditions, as shown on the Circulation Plan (Exhibit No. 12 of the Specific Plan).
.020 Site Screening Standards. The following provisions shall apply in addition to the specific requirements set forth in each residential development area:
.0201 Where there is an intervening slope bank or view opportunity, the height of site screening may be reduced to five (5) feet, and may be constructed with solid materials, open metal work and/or plexiglass, or any combination thereof, based on view and sound attenuation conditions.
.0202 Any fencing located in a manner that may obstruct the view from a public right-of-way shall consist of decorative, open-work materials, unless otherwise required for sound attenuation and approved by the Planning Commission or City Council.
.0203 Any wall required adjacent to an arterial highway or expressway shall be constructed, either along and adjacent to the property line separating such development from the arterial highway or expressway, or at the top of the slope adjacent to said arterial highway or expressway, whichever is the higher elevation. The top of said wall shall be a minimum of five (5) feet above the elevation of the building pads of dwelling units closest to the arterial highway or expressway, regardless of whether the wall is constructed on the property line or at the top of the slope. The wall may be constructed with solid materials, open metal work, and/or plexiglass, or any combination thereof, based on view and sound attenuation conditions.
.0204 Site screening up to seven (7) feet in height may be permitted by the Planning Commission or City Council for sound attenuation purposes, based on an acoustical study; provided, however, that increasing the height of site screening in Development Area Nos. 102 and 105 shall not be permitted.
