Landscaping. The overall intent of this standard is to achieve, where possible, a well-landscaped site that takes into consideration the surroundings and the total environment. That is, consideration shall be given to preservation of natural and existing vegetation as well as new plantings throughout the entire site plan. The Planning Board shall take into consideration the location of the structures and parking areas and their proximity to adjacent buildings and/or lots. Consideration shall be given to planting along property lines, buffer areas and along the walls of the building or structure, where possible, without impeding the operations of the facility. However, if there is substantial natural vegetation on site that services the requirements, i.e., screening, aesthetics, etc., the Planning Board shall not require additional landscaping except where deficiencies exist.
