This will be a discussion of research that looked at growing trees near sidewalks and in urban plaza situations. The sidewalk research shows practical ways of reducing sidewalk damage with treatments either alongside or underneath pavement. The urban plaza research compares tree and root growth in supported pavement, gravel based structural soils, and sand based structural soils. This is “must know” information for those involved in the design, installation or maintenance of trees near concrete.
