NOTES
1. There are 159 trees as part of the Arborist Report, providing 301 tree unit credits. 5 of the trees are
µ proposed to be removed due being non -viable. The 4.86 acre site requires 121.5 tree unit credits:
The existing trees provide tree unit credits exceeding the minimum requirements.
�— — 2. No clearing shall be allowed on a proposed development site until the tree retention and landscape
I jr _ _ _ _ _ _ — plans have been approved by the city of Federal Way. L
3. No disturbance area shall be established for each tree to be protected. The no disturbance zone
CY
shall be equal to the critical root zone which is defined as 12 inches radius for every one inch of tree O
4— diameter measured at four and one-half feet above ground. Any other no disturbance area Q W
_ proposed by the applicant shall be determined by a qualified arborist and sub'ect to review and O CO
approval by the director. E; (n Q 0

Izone of the tree(s).
7. No trenching is allowed in any critical tree root zone areas,
--- -- 8. No installation of any impervious surfaces is allowed in critical root zones. Where road or sidewalk
r— PROPOSED MEMORY CAREBUILDING - I 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
_ � I tree roots.
9. Tree protection areas (i.e., critical root zone) must be prepared to better withstand the stresses of
D l 8 the construction phase by, if necessary, fertilizing, pruning, and mulching around them well in

encroachment would not be detrimental to the health of the tree.
