(d) Screening of outdoor storage and trash collection areas shall be accomplished by one or both of the following methods:
(i) Dense evergreen shrubs and/or trees planted to provide a year-round sight-obscuring screen to achieve a minimum height of six feet within two years of planting.
(ii) A solid or otherwise sight-obscuring fence or wall at least six feet in height.
(2) Commercial and industrial side and rear yard landscaped areas adjacent to residential districts must contain a six-foot-high continuous solid screen.
(3) For security purposes, portions of the required screening, not to collectively exceed 20 linear feet along each street or alley adjacent to the lot from which vision is obscured, may be left unobstructed and open to view.
(4) Trash collection areas provided for multiple dwellings and provided in all office, C-1, CR, BP, and C-3 districts shall be located within six-foot-high site-obscuring structure which provides a visual screen from any abutting street. In no case shall such enclosure and trash collection receptacle(s) be permitted within the required front yard setback areas.
(5) Loading and service areas shall not face any residential zone, unless no other location is possible. Loading and service areas adjacent to or across a public street or alley from a residentially zoned district shall be screened with a sight-obscuring structure matching the architecture of the building:
(a) The structure shall be set at the back of any required landscape buffer.
(b) The structure shall not encroach into any required landscaped area.
(c) Any required landscape buffers shall be graded with a 15 percent slope, creating a berm that terminates in the screening wall.

(e) Live vegetation requirements in the landscape buffer shall be increased to the following rates:
(i) Trees shall be provided at a minimum rate of one tree for every 10 linear feet of property line and planted in groupings of three trees, with groupings spaced no more than 30 feet on center.

(6) Parking lots that abut a public street shall be buffered with:
(a) Live vegetation consisting of trees, shrubs and ground cover.
(b) All plant material used for parking lot buffers shall be managed and/or maintained to provide clear views between three and eight feet above the ground surface.
