In all districts except the “C-TS” Town Square Business District, in connection with every building or part thereof hereafter erected having a gross floor area of 10,000 square feet or more, which is to be occupied by manufacturing, storage, warehouse, goods, display, retail store, wholesale store, market, hotel, hospital, mortuary, laundry, dry cleaning or other uses similarly requiring the receipt or distribution by vehicles of material or merchandise, there shall be provided and maintained on the same lot with such building at least one off-street loading space for each 20,000 square feet, or major fraction thereof, of gross floor area so used in excess of 10,000 square feet.

   1.   Each loading space shall be not less than 10 feet in width and at least 25 feet in length.

   2.   Such space may occupy all or any part of any required yard or court space, except where adjoining an “R” District, it shall be set back five feet and an opaque screen of six feet in height shall be installed and shall be maintained along all “R” District boundaries. In addition, except at designated access points, wheel barriers shall be installed along the outside boundaries of any parking area. The wheel barriers shall be installed in such a manner as to prevent a parked vehicle from encroaching into any required setback. The screen shall be in line with the front of any adjoining residential structure in any adjoining ‘R” District or the front of the proposed commercial structure, whichever is the lesser front yard setback. However, if the adjoining “R” District property is vacant, the front yard setback for the “R” District shall apply. A six-foot-high opaque screen shall not be required along adjoining streets or adjoining alleys. An opaque screen of three feet shall be installed and maintained along each street side lot line of a corner lot where the premises is across from any “R” District. The opaque screen shall not extend closer than 25 feet to the front property line. An opaque screen of three feet shall be installed and maintained along each alley line where the premises is across from any “R” District. The opaque screen need not extend beyond the opaque screen installed along the street side lot line. Where there is a difference in elevation on opposite sides of the screen, the height shall consist of one or any combination of the following:

      A.   Wood or masonry walls or fences when constructed of materials which provide openings of less than 50 percent in area of the vertical surface of the wall or fence.

      B.   Berms constructed of earthen materials and landscaped.

      C.   Plant materials when used as a screen shall consist of compact evergreen plants. They shall be of a kind or used in such a manner so as to provide their screening function within 18 months after initial planting. The Zoning Enforcement Officer shall require that either A or B above shall be installed if, after 18 months after planting, plant materials have not formed an opaque screen or if an opaque screen is not maintained. A wall or fence may be combined with the plant materials. However, if such a wall or fence is constructed of materials which provide openings of more than 50 percent in area of the vertical surface of the wall or fence, it shall not be considered a part of the opaque screen and it shall be located on the parking area side of the plant materials.

      D.   When the finished elevation of the property is lower at the boundary line or within five feet inside the boundary line than an abutting property elevation, such change in elevation may be used in lieu of or in combination with additional screening to satisfy the screening requirements for this district.
