4.5.6 Construction

Protecting new and existing trees and minimizing soil compaction during construction is essential to maintain infiltration and adequate growing characteristics in the built environment. This is particularly true in urban areas. The designer should pay close attention to construction sequencing and material staging from the planning through construction phases as well as tree protection measures after the project is completed. It is also important to protect construction site soils from compaction and contamination in tree planting areas (see Section 4.2.5: Construction).
