Such landscaping shall be <br /> incorporated into a minimum of a five-foot wide landscaped bedding area <br /> located between, and in addition to the required building sidewalk and the <br /> first vertical wall of the building facade. Large commercial planters or <br /> alternative designs may be used to meet this criteria(See Figure 4-18.e). <br /> b. Bufferyards. Bufferyards, rather than setbacks, shall be required <br /> along all collector and arterial roadways, which include an unbroken(except <br /> for required driveways, sidewalks, and other public safety elements), <br /> landscaping area no less than 30 feet in width and planted according to <br /> Buffer standards.
