(A) Applicability. All parking areas in excess of 40 spaces for all uses except parking areas for single-family or two-family dwellings.
(B) Types of landscaping required. Two types are required within each parking area as follows:
(1) Perimeter landscaping. Parking area perimeters which are adjacent either to public rights-of-way or residentially used property must landscape perimeters with minimum eight-foot wide strips of landscaping. Both trees and shrubs are required via the following formula:
(a) Trees: required at the rate of one canopy tree for every 200 square feet of required planting area or one understory tree for every 150 square feet; and
(b) Shrubs: shrubs are required in addition to trees and at a rate of one per every 50 square feet of planting area.
(2) Interior landscaping. Landscaping within the interior of parking areas is important for aesthetics and also functional in that landscaping moderates heat, glare, wind and other climatic effects produced by paved areas. Accordingly, interior parking area space is to be landscaped as follows:
(a) Trees: required at a rate of one per 16 parking spaces. At least 40% of required trees must be large maturing trees with a minimum caliper of two and one-half inches measured six inches above ground at the time of planting; small maturing trees must have a minimum caliper of one and one- half inches measured six inches. Twenty-five percent of the trees throughout the parking lot must be evergreen.
(b) Shrubs: required at a rate of three per 16 spaces. Must be evergreen and at least two and one-half feet tall when planted with an average height of five to six feet expected as normal growth over a four-year period. Twenty-five percent of shrubs may vary from the above as follows:
1. May be deciduous or evergreen; and
2. May be two feet tall when planted provided three to four feet growth is anticipated over a four-year period.
