Which of the following determines the planting of trees or shrubs along a sidewalk?

• A. How Much It Sheds
• B. How High It Gets Before Branching
• C. When It Is Planted
• D. How Sticky The Leaves Are

Answer: (B)

This is about guaranteeing pedestrian clearance and maintenance access under a sidewalk. The key factor is how high the tree grows before its branches begin. If a tree keeps a tall, clear trunk before branching, the branches stay high above the walkway, reducing the risk of limbs encroaching on the sidewalk and making pruning or utility clearance easier. That vertical development pattern directly determines whether a tree or shrub will fit safely and neatly along a sidewalk.

The other factors don’t influence sidewalk layout in the same way: how much it sheds affects litter and cleanup, not space above the pavement; when it is planted affects establishment but not the eventual branch height; and how sticky the leaves are has no bearing on sidewalk clearance.
