1971 Comments: The trees are of a typical rounded form and uniform in height and spread. They add considerable beauty and shade to the street as well as to the homeowners' properties. Two serious problems associated with Acer platanoides are heavy shade they provide and the shallow root systems that are evident in the detrimental effects seen on the area under the trees.

1997 Comments: These Norway Maples have done well. The annual twig extension growth averages 6 to 12 inches per year. One of the keys in this situation is that the plants are in a lawn setting rather than a tree lawn or sidewalk cut. This results in less stress, faster growth, and higher survival.
Eight-nine percent of the overall planting survived (8 of 9 trees). The 1997 data in the table are based on four trees.
