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 City of Edmonds • Incorporated August 11, 1890 • Sictar C:itu - HOkinan Janan 4t3 �' � - '+ -- - Z I - ""p, - 0 72 'W MPI ;Al TzF; vzL. 09 it 41 . . . . . . . ... if, rt Ma IL M Cie PIN.. . 10326 45th Ave NE Seattle WA 98125 [206] 522 7262 Phone/ Fax www.treeinspector.com Jared Bond, City of Lynnwood,.

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. 4 16854 76th Ave W. 1 2 3 Prevai ina�/ wind.— — — — — — — — — — — — — — — — — — — — Approximate bank edge. 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 i Robert W. Williams C.A.
