RE: Removal of two dead trees north of Lynnwood treatment plant.
Dear John:
Sorry this has been so long coming.
GARY HAAKENSON
MAYOR
The two trees you showed me located just north of the Lynnwood waste water treatment plant
are obviously dead or dying. This is supported by both my observation, the photos submitted by
you and the arborist report submitted by you. Because of this condition, staff agrees that they are
potential hazards and removal of those trees are waived from the requirement of obtaining a tree
clearing permit.
Feel free to call me or someone in our planning department if you have similar issues you need
to address, 425.771.0220.,1

PUBLIC WORKS DEPT.
Concerns have been raised about the health and stability of trees on the
property of. the City of. Lynnwood treatment. plant, located at.1:7000 7.6th Ave W.
The trees are on the northern boundary of the property immediately adjacent to a
home at 16854 76. Ave-W. In order to assess the condition of the trees a tree
inspection. was- made.
Tree Inspection.
Individual tree inspection begins at ground level. Here, tree species, soil
quality, rooting conditions, soil level, irrigation and drainage characteristics can
be observed. Soil is a living micro -system that relies on an active working
relationship between material and living components. The physical condition of
the soil is most commonly adversely effected. The quality of the soil may be
1
assessed in its ability to contain and disperse available moisture and the level of
soil compaction may be tested to evaluate the aeration capacity of the soil. Some
soil types are easily compacted and although they are high in nutrient quantity,
little of that nutrient quality is available to the growing tree. The heavy equipment
used in construction or frequent traffic of any kind can cause sensitive soils to
become compacted. Compact soils cause problems by restricting the trees ability
to discharge the gasses produced as part of the growth cycle. The visible parts of
the tree; the trunk, branches and leaves live in balance with the unseen roots.
Damage to the soil leads to inhibited root growth causes a lack of vitality and
decline within the tree as a whole.
If signs of stress are present a soil test may be made to assess the fertility
of the soil. Testing establishes the presence and degree of vital nutrients and
micro -flora. Vital soil is essential to vital tree growth, the presence of nutrients
and organisms within the soil mean that growth can continue. An imbalance of
nutrients can cause poor vitality; often exhibited by leaf discoloration or lack of
annual growth. Poor nutrition will slow growth and can diminish the trees natural
defense mechanisms and expose the tree to disease.
In nature, few tree species grow alone; the forest is their natural and
protected setting. Whether native or introduced, irregardless of a trees origin,
trees in a landscape setting demand special attention. Each individual tree is the
product of the local environment, their success and well being rely on our care.
Looking at the overall picture, the health of the soil, turf and other plants
and trees can reveal the cause of disease, or indicate potential problems. The
presence of certain species of fungus can indicate decay. Certain decay fungi
may destroy support tissues and leave conductive tissues unharmed. The tree
may appear healthy and continue to grow until the internal decay outpaces. the
new outer growth.
A root crown examination may be necessary if root decay is suspected. By
removing the soil at the base of the tree, the location, health and condition of the
absorbing and support roots can be determined.
r.
In the primary examination of the root crown and trunk a mallet is used to
test for loose bark. Bark lifting can indicate dead or hollow areas and give signs
of the presence of decay in the root crown zone and at the base of the trunk. The
mallet may be used to "sound" for decay but this has limited reliability in. If decay
is suspected the tree will be tested using the Resistograph. The Resistograph is
an instrument that inserts a constant velocity probe into the suspect area of the
tree. The resistance to the probe is graphed by the machine. The graph profile
can tell a great deal about the internal character of the wood. Internal defects can
be detected, cracks, hollows and early stage decay. The type of decay and its
effect on the stability of the wood depends on the species of fungus involved. Soil
and root tissue samples may be taken to determine the cause of disease by
laboratory testing.
. The inspection continues with an
evaluation of the tree crown, first by eye or
with the use of binoculars then, if
necessary, by climbing into the canopy of
the tree. The color, size and condition of
the leaves, trunk, branches and twigs is
assessed. The form and formation of all
the trees components give information
about health, vitality and structural
strength. The crown density, the number of
leaves on each stem, and past and current
growth extension, indicate current health
and previous problems. Changes in growth
rate in older growth may indicate prior
disease or injury. An evaluation of the general growth habit will reveal any
problems related to vigor, or the genetic component of tree growth. Previous
treatments such as pruning or cabling are observed, the quality of the work, and
its effect on the tree. Any growth abnormalities are noted : weak limbs,
discolored or missing bark, cracks or cavities in branches or trunks and the
3
presence of disease within the canopy of the tree in the form of leaf blight, stem
canker or insect activity.
Trees produce adaptive growth to compensate for the stress related to
growth and injury. The shape and formation of limbs and trunks can show the
ability of the tree to compensate for weakness or indicate internal problems that
may lead to failure. The interpretation of these changes in form is part of a
growing body of knowledge pioneered in Europe. The knowledge is not new but
the application is: Dr. Claus Mattheck of the Karlsruhe Institute and colleagues,
have developed a system of structural evaluation based on the principals of bio-
engineering. I have. chosen to use this approach to augment my own knowledge
and experience. The observations and results of the field work and testing are
given in the body of the report, they are followed by a statement of my
conclusions and my recommendations for treatment.
Observations.
This tree inspection was made due
to concerns that arose following the
decline of the tree shown with the red
arrow at left. This tree, a Douglas Fir
(Pseudotsuga menziesh) 22" Diameter at
Breast Height is one of three Douglas Fir
on the northeastern property boundary of
the treatment plant. The treatment plant is
located at the base of a steep ravine
oriented west toward the Puget Sound.
These trees are located at the top of the
bank above the treatment facility.
Immediately to the north of the trees are
residences. The following illustration gives an approximation of the location.

Sketch showing the approximate location of the trees in relation to
There is little or no protection to the south west and the open waters of the
sound. The trees, standing alone at the top of the bank, are highly exposed to the
prevailing wind.
The rapid. decline of tree 1 is typical of root. related fungal. pathogen
invasion. These trees are in close enough proximity for the disease to spread
from one to the other. In order to assess the current condition of the base of the
trees the Resistograph was utilized. The Resistograph is an instrument, or
rather a family -of instruments, for detecting decay and defects in trees and
timber. The instrument measures the resistance to a needle inserted into the
wood under constant drive. In the M300 model, the constant drive is provided by
either a crank and flywheel or a battery driven electric motor. The resistance to
the needle tip is transferred through an "intelligent" satellite gearbox to a pointer
on the top of the instrument that maps the result on a waterproof wax paper
printout. Drilling resistance correlates to the mechanical properties of the wood.
Defects such as cracks areas of decay, hollows and to a certain extent tree ring
structures can be detected and mapped. The resistance is mapped on a 1:1
scale on the wax paper, giving a clear graphical representation of the mechanical
properties of the wood. The Resistograph utilizes a 3mm needle tip and a 1.5mm
flexible needle that tends to "squeeze" between the fibres of the wood causing
very little wounding.
5
The Resistograph charts are shown below and should be read from right
to left areas of lower strength are shown by a lower reading on the scale.
The first test was made on tree 1. The test shows a relatively normal
profile with a loss of resistance toward the end.
Tree 2. Produced an unusual resistance pattern I suspect there may be
some early decay present toward the center of the tree
Tree 3. Showed a normal pattern of gathering resistance with no indication
of defect or decay.
Conclusions and Recommendations.
In my opinion the trees are only performing minor functions in slope
retention. Tree 1. Is located on a flat area at the top of the slope. Trees 2 and 3
are at the very top of the slope. The crown of the trees are diminished and
deflecting little water and the root systems will become less supportive by
degree. Root disease is present on site and the trees are located in close
proximity. It is to be expected that the disease may spread to the remaining trees.
This may take ten years and could happen within two, the spread of the disease
is largely unpredictable. When crown symptoms appear in the above ground
C.
parts of the tree root disease is often in an advanced stage. The decomposition
of the root system depends on the specific pathogen.
Clearly the tree that is near death should be removed. Given the exposure
of the remaining trees, their poor crown form and limb distribution on the trunk,
the remaining trees should also be considered for removal at this time. I would
suggest that you consider replacement plantings along the top of the bank.
Western Redcedar is less susceptible to the most common root disease in the
pacific northwest and would provide a fibrous rooting system.
I hope this information proves useful, please let me know if I can be of
further help.
Yours sincerely
it
