(a) Parking Lot Trees.
(1) Where large parking lots (those containing 30 or more parking spaces) are proposed, one tree per 15 parking spaces shall be required to be planted in a landscape island. Honey Locust, Ash, and Hardy Rubber trees are the 3 types of trees that are best able to tolerate the harsh conditions, such as drought, that characterize large parking lots.
(2) In order to better facilitate the long-term health of individual trees, no parking lot island shall be less than 7 feet in width or 7 feet in length. Such island may be placed in random fashion, as opposed to being located at either the ends or midpoints of parking rows. Where agreed to by the Planning Commission, small clusters of parking lot trees may be substituted for individual planting islands. In such instances, at least 50 square feet of soil area shall be reserved for each tree that is planted. No shrubs or bushes shall be permitted to be substituted for tree clusters, nor shall they infringe upon the aforementioned 50 square feet per tree soil requirement.
(3) In order to prevent visibility problems, all parking lot island trees shall be clear of branches to a point 7 feet above the surface of the island in which they are planted. All such trees shall have the height of 10 to 12 feet, and shall have calipers of at least 2 inches as measured 4 feet above the surface of the parking lot island.
