A. Street trees, by virtue of a narrow tree trunk, provide transparency at the pedestrian’s eye level, permitting a visual grasp of extensive areas of a city.

B. The type, spacing, structure and pattern of street trees create a discrete rhythm that results from the arrangement of trees, expressing the particular site.

C. Street trees create a smaller scale of space with their canopies that are sympathetic to the movement and perception of pedestrians.

D. The diversity of individual trees is subordinated to the repetitive pattern of the whole, which unifies the individual parts into a single whole.

E. Street trees, when formed from a single tree species, create homogeneity of texture, pattern, light and shade, resulting in a collective impact that is more important than the individual trees.

F. The ground surface is visually unobstructed to permit a clear expression of trees rising out of the ground.
