2. Fencing: A wood fence a minimum of six feet (6') in height with ninety five percent (95%) opacity is required along the entire buffer yard except for the area along the side yard that would be within the front yard setback or would block views at driveways or intersections. The fencing will be located on the interior side of the buffer yard with the required landscaping placed between the fence and the residential use. It is encouraged that the wood fencing be a style that is attractive and consistent on both sides such as board on board and shadowbox styles.

E. Variety And Mix: It is encouraged that a variety of species be used in the selection of required plant materials with indigenous materials making up a majority of plant material. However, at a minimum, twenty percent (20%) of the required plant material will be evergreen trees and shrubs. Care should be taken that evergreen plant materials be located in areas away from possible contact with road salt used for winter deicing purposes. It is encouraged that property owners and developers utilize ground covers, ornamental and native grasses, wildflowers, perennial and annual flowers to add color and interest to their sites.
