TOTAL PROPOSED TREE UNITS 239.5
TOTAL RETAINED & PROPOSED TREE UNITS 534.0 Tree Units EXCEEDS REQUIREMENT
1.No disturbance area shall be established for each tree to be protected. The no disturbance zone shall be
equal to the critical root zone which is defined as 12 inches radius for every one inch of tree diameter
measured at four and one-half feet above ground. Any other no disturbance area proposed by the applicant
shall be determined by a qualified arborist and subject to review and approval by the director.
The no disturbance zone shall be identified during the construction stage with:
(a) A temporary five-foot chain-link fence; and
(b) 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.”
2.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.
3.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.
4.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).
5.No trenching is allowed in any critical tree root zone areas.
6.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.
7.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.
8.Alternative protection methods may be used if accepted by the director to provide equal or greater tree
protection.
9.Encroachment into the no disturbance area may be allowed where the director determines encroachment
would not be detrimental to the health of the tree.Lyon Landscape Architects1015 Pacific Avenue, Ste 203Tacoma, WA 98402253-209-4053Moghan@LyonLA.comPermit SetFederal Way, WASouth 304th StreetWoodlands @ Redondo Creek17Soundbuilt HomesL1.5Landscape PlanGraphic Scale: 1" = 20'-0"
