(A) Landscape buffer areas minimize the potential for nuisances created when zoning districts or land uses of varying intensities abut, and shall be required for all new construction subject to these regulations. Landscape buffer area requirements shall be applied along property or right-of-way lines and at the perimeter of vehicular use areas. Landscape buffer areas shall also be applied adjacent to designated parkways and scenic corridors.
(B) Landscape buffer areas shall be provided on the site of the more intense use or zoning district except when the more intense use was present prior to the effective date of this regulation. When more than one landscape buffer area requirement applies, the more restrictive standards shall be used.
