The objective of parking lot landscaping is to enhance the lot, provide a buffer zone between adjacent land uses, and to subdivide large parking areas. Landscaping should never obstruct the view of motorists in a parking facility, or interfere with parking maneuvers.
Provide sufficient setbacks for all plants, so that the front or rear overhangs of cars do not damage or destroy them. Ensure that placing and maintaining shrubbery or other plants near entrances and exits does not restrict sight distance. Also consider the growth pattern of the plant, so that a small plant will not develop into a major sight restriction in the future.
The planted area within and around a parking lot is usually based on a proportional amount of "green" space to paved area. Typically, a minimum of 10 percent of the area is utilized for landscape plant material.
