Tree Space Design
The ability of trees to grow and thrive is directly related to the amount of soil available for tree roots. As a result, trees placed 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.
The resulting report, Tree Space Design: Growing the Tree Out of the Box, includes a matrix of soil volume recommendations and root-friendly design methods, intended for inclusion in design standards and use in individual projects. Outlined recommendations, if followed, will not only yield larger, healthier trees, but will minimize damage to paved surfaces, creating a better streetscape environment.
Treespace Design: Growing the Tree out of the Box received the Maryland and Potomac Chapters of the American Society of Landscape Architects Chapter 2008 Merit Award for Communications.
