The following trees may be used for screening, but they are recommended especially for shading streets and parking lots. Unless otherwise noted, they will grow rapidly. Each species will attain a mature spread of at least thirty (30) feet.
(1) Red maple (Acer rubrum). Height: forty (40) to fifty (50) feet; spread: twenty-five (25) feet or more. This tree is an example of a maple which is not recommended where there will be high concentrations of air pollution. However, with its excellent shading characteristics and beautiful colors, it should not be ignored. This tree grows rapidly, but, unlike the Norway maple, it does not become brittle with age. The red maple is a native tree which is usually found in moist, even swampy areas, but it adapts well to a variety of situations. Although subject to maple insects and diseases, it is usually a long-lived tree.
(2) Honey locust (Gleditisia triacanthos). Height: fifty (50) to seventy-five (75) feet; spread: twenty-five (25) feet or more. Its open, spreading form and feathery leaves may give the honey locust a frail appearance, but it is, in fact, a quite sturdy tree, notable for its resistance to storm damage. It is a native tree which is drought-resistant and adaptable to city conditions. Grass and shrubs thrive beneath a honey locust because it casts light shade. This tree is especially useful for its ability to be transplanted at a relatively advanced age. Accordingly, it may be used for immediate effect in a landscape design. The honey locust has its pests and diseases, but it is fairly hardy. Thornless and fruitless varieties such as Moraine are recommended.
