The ability of trees to grow and thrive is directly related to the amount of soil available for tree roots. As a result, trees in typical urban "tree boxes" tend to be short-lived since their needs can quickly exceed the capacity of the space.

Casey Trees convened a panel of experts to develop design recommendations that would provide street trees with adequate soil volume while maintaining sufficient space for pedestrian circulation.
