ADDITIONAL TREE PROTECTION NOTES:
The no disturbance zone shall be identified during the construction
stage with:
A temporary five-foot chain -link fence; and
Tree protection signage attached to the fence which reads "TREE
PROTECTION FENCE — No soil disturbance, parking,
storage, dumping, or burning of materials is allowed within the
Tree Protection Fence."
No soil disturbance, parking, storage, dumping, burning of
materials, impervious surfaces, fill, excavation, or storage of
construction materials shall be permitted within the no disturbance
area.
If the grade level around the tree is to be raised by more than one
foot, a rock well shall be constructed. The inside diameter of the
rock well shall be equal to the diameter of the tree trunk plus 10
feet. Proper drainage, and irrigation if necessary, shall be provided
in all rock wells.
The grade level shall not be lowered within the larger of the drip line
of the tree(s) or the critical root zone of the tree(s).
No trenching is allowed in any critical tree root zone areas.
No installation of any impervious surfaces is allowed in critical root
zones. Where road or sidewalk surfaces are needed within critical
root zones, unmortared porous pavers or flagstone (rather than
concrete or asphalt) may be used. Boardwalks or bridging may
span root zones without harming the tree roots.
Tree protection areas (i.e., critical root zone) must be prepared to
better withstand the stresses of the construction phase by, if
necessary, fertilizing, pruning, and mulching around them well in
advance of beginning any construction activities.
Alternative protection methods may be used if accepted by the
Arborist to provide equal or greater tree protection.
Encroachment into the no disturbance area may be allowed where
the Arborist determines encroachment would not be detrimental to
the health of the tree.
