A minimum of fifty percent of every landscape island shall be planted with live plant material, such as shrubs, ground cover or turf grass to a maximum height of thirty inches at maturity. The entire area of the landscape island shall be covered with organic mulch.
6. Shrubs shall be no greater than thirty inches in height and the branches of trees shall start no less than six feet above the pavement, to ensure proper visibility within the parking lot.
D. Parking Lot Screening: All parking lots, regardless of number of parking spaces or of intended use and service or loading areas, must be landscaped around their perimeters as follows:
1. A minimum seven foot wide landscape area shall be provided around the parking lot where it abuts another parcel or right of way.

Fifty percent of the landscape requirements shall be made up of evergreen trees and shrubs and fifty percent deciduous trees, ornamental trees and shrubs.
F. Fencing And Walls: Fencing and walls are to be used where screening is required but there is insufficient depth in the landscape area to exclusively use plant materials and achieve satisfactory results.
