This presentation cover how to integrate large urban trees and their associated soil volumes into the densest urban areas. Two research studies compare supported pavement with load bearing modules and structural soil treatments. The researcher, a soil scientist, and a landscape architect present the implications for the profession.

Learning Outcomes:

Learn to identify urban soil conditions and strategies to appropriately address long-term growth of trees.
Discuss the latest research on the different kinds of structural soils, their composition, and their benefits and drawbacks.
Assess which soils strategies are best to use given the requirements of a particular site.
Examine case studies where the use optimum soils strategies had a meaningful impact.
