Where shift changes may cause substantial overcrowding of parking facilities, the planning commission may require additional spaces.

(4)
Medians. Any traffic median or island, either on or off site, shall be fully landscaped with trees, shrubs, or, grass, or a mixture of the three. In any case, however, the landscaping shall include trees unless deemed inappropriate by the planning commission, or puts the safety of patrons, residents, or others in jeopardy by its design.
(5)
Islands within Parking Areas. On double rows of parking stalls, there shall be one 40-foot by nine-foot landscaped island on each end of all parking rows, plus one 40-foot by nine-foot landscaped island to be placed at a minimum of every twentieth parking space.

Landscaped islands at the ends of parking rows shall be placed and shaped in such a manner as to help direct traffic through the parking area. There shall be a break in parking rows at a maximum of 40 parking stalls for each double row of parking for the purpose of facilitating traffic circulation on the site. Each island on double parking rows shall include a minimum of two trees per planter. Islands on a single parking row shall have a minimum of one tree per planter. The purpose of the landscaped area is to provide shade relief to the parking area and all vegetation shall be placed to this end.

The center walkway shall be placed roughly at midpoint of the parking area, but shall align with the front entrance to the main building. Trees along the center walkway shall be placed a minimum of every 30 feet, but are encouraged to be offset from one another to create a feeling of greater coverage. Where parking configurations are long and narrow, the center walkway may be removed as long as there is a maximum of 250 feet to the nearest walkway.
