                        (1)        Provide a ten-foot minimum landscaped setback area exclusive of that required for sidewalks or utility easements between the street and the parking lot, to be planted with trees and shrubs in accordance to the requirements set forth in section 505.4, Plant Requirements and Sizes.

                        (2)        Where substantial grading is necessary and results in a parking area lower in elevation than the surrounding or adjacent right-of-way, the resulting embankment should be planted with low shrubs and shade or ornamental trees. A minimum of ten feet of landscaping should be provided between the street and the parking lot.

                        (3)        Where feasible, create a berm in accordance with subsection 505.4 for planting lawn, ground cover, shrubs and one tree every 35 feet.

                        (4)        In cases where a quality woodland exists, preserve the existing trees between the parking area and the right-of-way. Provide additional evergreen or deciduous trees to achieve a visual buffer. Existing trees shall be protected during construction under the guidance of a professional horticulturist.

            (B)       Provide a minimum of five percent interior landscaping for the purpose of planting shade trees and shrubs. The following alternatives are recommended:
