Grade changes are often necessary during new building construction.
Any addition or subtraction from the natural soil grade will adversely affect trees and shrubs.
Sometimes very young plants adjust to minor soil grade changes. However, older, well-established trees and shrubs are very sensitive to grade changes around their root systems.
