Jim Ferrell, Mayor
The City of Federal Way has received and has reviewed site plans for a single family home received on
June 28, 2016, for the Lake Haven Estates Lot 11 at 1640 SW 341" Street. According to the Lake Haven
Estates final plat general notes, two conditions are required to be met prior to the issuance of the building
permit as outlined below:
Prior to issuance of a building permit for a single family residence for Lot 11, the applicant must
provide the City of Federal Way a landscape plan which clearly shows the location of all of
the trees on the adjacent Nelson property (PIN 192104 9032). The applicant shall also submit a
letter from a certified arborist stating whether tree protection measures on the Lake Haven
Estates Lot 11 are necessary to keep the Nelson's trees safe. If the arborist's letter indicates that
tree protection measures are in order, those tree protection measures shall be shown on a tree
protection plan to be submitted to the City in conjunction with a building permit for a new single
family residence for Lot 11.
A significant tree retention and replacement plan shall be provided to the City of Federal
Way at the time of each building permit submittal and issuance for a new single family residence
on each lot. Each individual lot shall meet the significant tree retention and replacement standards
of FWCC 22-1568(B), which requires retention and/or replacement of at least 25 percent of the
significant trees on each individual lot. Replacement trees will be required to be planted prior
to final approval of each new single family residence.
Prior to the issuance of a building permit the conditions outlined above must be satisfied. If a complete
tree inventory of the Nelson property is not possible, a property line examination of the trees and their
prospective root systems situated upon the property line will satisfy this condition. If you have any
questions contact Planning Intern David Lee at (253)835-2622, david.lee@citvoffederalway.cotil.
Sincerely,
David Lee

Introduction
I have reviewed the trees along both sides John Nelson's/Lakehaven Estates property line in
Federal Way, WA. The purpose of the evaluation was to determine the impact to the trees on
the Nelson property from tree removal and construction on the Lakehaven Estates site.
Observations
Soils
According to the King County Soil Survey there is one soil type along the subject property
line. The soil type is the Alderwood gravelly sandy loam, a moderately deep, moderately
well drained soil found on glacial till plains. It is formed in ablation till overlying basal till.
A weakly cemented hardpan is at a depth of 20 to 40 inches. Permeability is moderately
rapid above the hardpan and very slow in the pan. Available water capacity is low.
The effective rooting depth for trees is 20-40 inches. A perched seasonal high water table is
at a depth of 18-36 inches from November to March. The potential for windfhrow of trees
is moderate under normal conditions. New trees require irrigation for establishment.

Existing Trees
The trees on the site are a stand of native and introduced species. The species that are
located along the property lines include Douglas -fir (Pseudotsuga menziesii), western red
cedar (Thuja plicata), red alder (Alnus rubra), bigleaf maple (Ater macrophyllum), giant
sequoia (Sequoiadendron giganteum), apple (Malus sp.), Pacific madrone (Arbutus
menziesii), black cottonwood (Populus trichocarpa), Port -Orford cedar (Chamaecyparis
lawsoniana), bitter cherry (Prunus emarginata) and two oak species (Quercus sp.).
The diameters of the trees range between 6 to 44 inches at breast height (4.5 ft. above the
groundline). Tree condition can be described as fair to good, with a few poor or dead trees.
There were no visible signs of significant disease or insect problems in the stand.
A total of 24 trees were evaluated on 3 properties. Eleven trees occurred on the Nelson
parcel near the property line. A Iist of the Nelson trees by species, DBH, the potential
impacts and necessary root protection are provided in Table 1. A list of all evaluated trees is
provided in Appendix III.
The root protection zones were determined by examination of the trees, the root systems, and
competition between the subject tree and surrounding trees for growing space under ground.
Based on these tree evaluations, the necessary root protection zones (RPZ) were determined.

Tree 91, the bigleaf maple is under the powerlines and has been topped. It is in poor
condition. It is recommended that this tree be removed and replaced by the Nelson's, with a
utility friendly trees (<20 ft. mature height).

Discussion
Six trees on the Nelson property may be impacted by cuts or fills during the Lakehaven
project. I have provided the necessary root protection zone distances in Table 1. Installation
of the tree protection fences at these locations will provide adequate protection of the Nelson
trees. The approximate locations of the tree protection fences are shown on the site plan in
Appendix II, but the map is not to scale.
Conclusions
To reduce the risk of tree damage along the Nelson property line, I recommend that the
following practices be considered:
1. Install a tree protection fence at the root protection zone distances prescribed in Table
1.
2. Potential activity to avoid along this edge includes:
a. Excavation within the root protection zones.
b. Care must be used during stump removal on the Lakehaven parcel to avoid
damage to adjacent trees. It may be necessary to grind stumps that are within
10 ft. of a neighboring tree.
c. If walls or fences are to be constructed, then care must be taken in digging
footings for these structures.
d. Fills may be possible, but should not impact more than 20% of the prescribed
root protection zone.
e. No trenching for underground utilities or other root or soil disturbing activity
should occur in the root protection zone.
f. If undesirable vegetation needs to be removed, then it should be carefully
hand cut or `plucked' with an excavator sitting outside of this projected root
protection zone.
3. Consider having WFCI present during site clearing along this north line.
In summary, if tree protection fences are installed as prescribed and care is used removing
any adjacent Lakehaven trees as prescribed, then the potential impacts to the Nelson trees by
the Lakehaven project is low.
Please give me a call if you have further questions

*Black cottonwood is a high risk tree near targets', Nelson trees are unshaded;
Note: Even healthy trees can fail under normal or storm conditions. The only way to eliminate all risk is to
remove all trees within reach of all targets. Annual monitoring by an ISA Certified Arborist or Certified
Forester will reduce the potential of tree failures. It is impossible to predict with certainty that a tree will stand
or fail, or the timing of the failure. It is considered an 'Act of God' when a tree fails, unless it is directly felled
or pushed over by man's actions.
