The following trees are recommended for use in all types of screens, and even though these trees are smaller than the trees listed in lists §§ 152.517 and 152.518, each of these trees will reach a height of at least 20 feet. The following selections are also recommended as shade trees and may be credited for meeting the 20% shading requirement for paved parking lots.
(A) River Birch (Betula nigra). Height: 20 to 40 feet; Spread: eight to 16 feet. The River Birch is a native tree which usually grows along stream banks. In landscape design, it is adaptable to either high or low locations, but still requires a lot of moisture. This tree has an interesting papery bark and a graceful branching habit. It has no special pest or maintenance problems.
(B) American Hornbeam (Carpinus carolina). Height: 20 to 30 feet; Spread: 15 to 20 feet. This native tree has a natural yet refined appearance. It is slow growing, but at maturity it serves as an excellent shade tree. Its fluted muscular trunk is an interesting feature. In the wild, the American Hornbeam is common in moist rich soil, yet, when used in landscape design, it is soil tolerant and does not require an unusual amount of water. It has no pests and no special maintenance problems.
