E. Where directed by Owner's Representative, extend pruning operations to restore natural
shape of trees and other plants impacted by construction activities.
F. Cut branches and roots with sharp pruning instruments, as specified. Do not break, chip
or mutilate.
G. Restrict vehicular and foot traffic, of all construction crews, to prevent compaction of soil
over root systems and within tree protection zones.
H. Erect fencing around all tree protection zones prior to commencement of clearing and
