a. A six-foot (6') high site obscuring fence shall be constructed and maintained along any property line between a residential use or residential zone and a commercial building in the CF zone when the commercial building is closer than thirty feet (30') from the property line. The fence shall be placed along the property line at an area parallel to the commercial building and shall extend a minimum of fifty feet (50') along the property line from both directions from the ends of the building.

b. Any commercial structure closer than thirty feet (30') to a residential use or residential zone shall provide a minimum ten-foot (10') wide tree-lined buffer from the commercial building to the adjacent residential use or zone. Trees shall be planted at least every ten feet (10') along the buffer area adjacent to the residential use or residential zone. Trees must be a minimum of two-inch (2") caliper measured one foot (1') off the ground and at least six feet (6') tall when planted. In addition to any required fencing, trees shall be of a variety that will mature to a height of at least twenty feet (20') tall in order to provide an increased visual barrier between the commercial use and the residential use.
