They can be summarized as follows: ASSIGNMENT Tina Gilbert of Unico Properties, contracted with Gilles Consulting to evaluate the trees at 1601 Lind Avenue SW in Renton, Washington. The property is being considered for redevelopment and the City of Renton requires an analysis of the trees as part of the permit process. This report provides the analysis. The information in this report can be utilized to create a Tree Retention/Preservation Plan as required by Renton Code.

I followed the protocol of the International Society of Arboriculture (ISA) for tree risk assessment. Published in 2011, the Best Management Practices, Tree Risk Assessment, ANSNI A300 Part 9 was developed to aid in the interpretation of professional standards and guide work practices based upon current science and technology. Using this process, now called the Tree Risk Assessment Qualification, or TRAQ for short, I performed a Level Two assessment which included looking at the overall health of the tree as well as the site conditions. This is a scientifically based process to look at the entire site, surrounding land and soil, as well as a complete look at the tree itself. In examining each tree, I looked at such factors as: size, vigor, canopy and foliage condition, density of needles, injury, insect activity, root damage and root collar health, crown health, evidence of disease-causing bacteria, fungi or virus, dead wood and hanging limbs. Tree Tags The trees were tagged and numbered 604 through 833. The tags are made of shiny aluminum approximately one inch by three inches in size and are attached to the tree with staples and a one foot strip of brightly colored survey tape. The tags were placed as high as possible to minimize their removal and were generally placed on the backsides of the trees as inconspicuously as possible. Please refer to Attachment 1, Site Plan for an orientation to the site and the approximate location of the trees. OBSERVATIONS The subject property is located on the southwest corner of Lind Avenue Southwest and Southwest 16th Street. The property extends west all the way to Raymond Avenue SW which has become the only entry onto the subject property. The subject property is somewhat horseshoe shaped with a small rectangle of property on SW 16th Street owned by Puget Sound Energy where they operate an electrical sub-station. Tag numbers were begun just west of the northwest corner of the Puget Sound Energy substation property along SW 16th Street. The numbers then circle the outer edge of the property in a counter clockwise fashion going south along Raymond Avenue SE, then down the south property line to Lind Avenue to the southeast property corner, then on to the northeast corner of the property, then wind around the buildings and parking lots to end near the southeast corner of the main building. Please refer to Attachment 1 Site Plan with Tree Numbers for the flow of the tag numbers. Evaluation of Trees at 1601 Lind Avenue, Renton, WA 98057 Gilles Consulting April 22, 2015 Page 5 of 39 In an effort to present the information and conclusions for each tree in a manner that is clear and easy to understand, as well as to save paper, I have included a detailed spreadsheet, Attachment 2, Tree Inventory/Condition Spreadsheet. All the same information from the ISA Tree Hazard Form is included in this spreadsheet and the attached glossary. The descriptions on the spreadsheet were left brief in order to include as much pertinent information as possible and to make the report manageable. The attached glossary provides a detailed description of the terms used in the spreadsheet and in this report. It can be found in Attachment 3, Glossary. A brief review of these terms and descriptions will enable the reader to rapidly move through the spreadsheet and better understand the information. Photo # 1: A Google Earth Image of the property The PSE Sub-station SE 16th Street Lind Ave SE Evaluation of Trees at 1601 Lind Avenue, Renton, WA 98057 Gilles Consulting April 22, 2015 Page 6 of 39 CONCLUSIONS AND RECOMMENDATIONS A total of 230 trees were evaluated and documented. There are no right-of-way trees impacted by the proposed expansion/redevelopment work. We were not able to accurately ascertain whether or not all of the trees are on the subject property. It is possible that some of the trees between numbers 732 to 759 may be on the PSE property. That said, any trees on adjacent properties are not impacted by the proposed redevelopment. Tree Protection Measures In order for trees to survive the stresses placed upon them in the construction process, tree protection must be planned in advance of equipment arrival on site. If tree protection is not planned integral with the design and layout of the project, the trees will suffer needlessly and possibly die. With proper preparation, often costing little or nothing extra to the project budget, trees can survive and thrive after construction. This is critical for tree survival because damage prevention is the single most effective treatment for trees on construction sites. Once trees are damaged, the treatment options available are limited. The minimum Tree Protection Measures in Attachment 4, Tree Protection Measures are on three separate sheets that can be copied and introduced into all relevant documents such as site plans, permit applications and conditions of approval, and bid documents so that everyone involved is aware of the requirements. These Tree Protection Measures are intended to be generic in nature. They will need to be adjusted to the specific circumstances of your site that takes into account the location of improvements and the locations of the trees. WAIVER OF LIABILITY There are many conditions affecting a tree’s health and stability, which may be present and cannot be ascertained, such as, root rot, previous or unexposed construction damage, internal cracks, stem rot and more which may be hidden. Changes in circumstances and conditions can also cause a rapid deterioration of a tree’s health and stability. Adverse weather conditions can dramatically affect the health and safety of a tree in a very short amount of time. While I have used every reasonable means to examine these trees, this evaluation represents my opinion of the tree health at this point in time. These findings do not guarantee future safety nor are they predictions of future events. The tree evaluation consists of an external visual inspection of an individual tree’s root flare, trunk, and canopy from the ground only unless otherwise specified. The inspection may also consist of taking trunk or root soundings for sound comparisons to aid the evaluator in determining the possible extent of decay within a tree. Soundings are only Evaluation of Trees at 1601 Lind Avenue, Renton, WA 98057 Gilles Consulting April 22, 2015 Page 7 of 39 an aid to the evaluation process and do not replace the use of other more sophisticated diagnostic tools for determining the extent of decay within a tree. As conditions change, it is the responsibility of the property owners to schedule additional site visits by the necessary professionals to ensure that the long-term success of the project is ensured. It is the responsibility of the property owner to obtain all required permits from city, county, state, or federal agencies. It is the responsibility of the property owner to comply with all applicable laws, regulations, and permit conditions. If there is a homeowners association, it is the responsibility of the property owner to comply with all Codes, Covenants, and Restrictions (CC&R’s) that apply to tree pruning and tree removal. This tree evaluation is to be used to inform and guide the client in the management of their trees. This in no way implies that the evaluator is responsible for performing recommended actions or using other methods or tools to further determine the extent of internal tree problems without written authorization from the client. Furthermore, the evaluator in no way holds that the opinions and recommendations are the only actions required to insure that the tree will not fail. A second opinion is recommended. The client shall hold the evaluator harmless for any and all injuries or damages incurred if the evaluator’s recommendations are not followed or for acts of nature beyond the evaluator’s reasonable expectations, such as severe winds, excessive rains, heavy snow loads, etc. This report and all attachments, enclosures, and references, are confidential and are for the use of the client concerned. They may not be reproduced, used in any way, or disseminated in any form without the prior consent of the client concerned and Gilles Consulting.

This spreadsheet was developed by Gilles Consulting based upon the Tree Risk Assessment in Urban Areas and the Urban/Rural Interface course manual and the Tree Risk Assessment Form, both sponsored by the Pacific Northwest Chapter of the International Society of Arboriculture, and the Hazard Tree Evaluation Form from the book, The Evaluation of Hazard Trees in Urban Areas, by Matheny and Clarke. The descriptions were left brief on the spreadsheet in an effort to include as much pertinent information as possible, to make the report manageable, and to avoid boring the reader with infinite levels of detail. However, a review of these terms and descriptions will allow the reader to rapidly move through the report and understand the information. 1) PROPERTY—Whether the tree is on or off the Subject Property, or a Right-of-Way tree. 2) TREE LOCATION—Relative placement of the tree. 3) TREE #—the unique tag number of each tree. 4) SPECIES—this describes the species of each tree with both most readily accepted common name and the officially accepted scientific name. 5) DBH—Diameter Breast Height. This is the standard measurement of trees taken at 4.5 feet above the average ground level of the tree base. i) Occasionally it is not practical to measure a tree at 4.5 feet above the ground. The most representative area of the trunk near 4.5 feet is then measured and noted on the spreadsheet. For instance, a tree that forks at 4.5 feet can have an unusually large swelling at that point. The measurement is taken below the swelling and noted, e.g. ‘28.4” at 36”’. ii) Trees with multiple stems are listed as a “clump of x,” with x being the number of trunks in the clump. Measurements may be given as an average of all the trunks, or individual measurements for each trunk may be listed. (1) Every effort is made to distinguish between a single tree with multiple stems and several trees growing close together at the bases. 6) DRIP LINE—the radius, the distance from the trunk to the furthest branch tips. 7) % LCR—Percentage of Live Crown Ratio. The relative proportion of green crown to overall tree height. This is an important indication of a tree’s health. If a tree has a high percentage of Live Crown Ratio, it is likely producing enough photosynthetic activity to support the tree. If a tree has less than 30% to 40% LCR, it can create a shortage of needed energy and can indicate poor health and vigor. 8) SYMMETRY—is the description of the form of the canopy, i.e., the balance or overall shape of the canopy and crown. This is the place I list any major defects in Evaluation of Trees at 1601 Lind Avenue, Renton, WA 98057 Gilles Consulting April 22, 2015 Page 31 of 39 the canopy shape, e.g. does the tree have all its foliage on one side or in one unusual area? Symmetry can be important if there are additional defects in the tree such as rot pockets, cracks, loose roots, weak crown, etc. Symmetry is generally categorized as Generally Symmetrical, Minor Asymmetry or Major Asymmetry: i) Gen. Sym.—Generally Symmetrical. The canopy/foliage is generally even on all sides with spacing of scaffold branches typical for the species, both vertically and radially. ii) Min. Asym.—Minor Asymmetry. The canopy/foliage has a slightly irregular shape with more weight on one side, but appears to be no problem for the tree. iii) Maj. Asym.—Major Asymmetry. The canopy/foliage has a highly irregular shape for the species with the majority of the weight on one side of the tree. This can have a significant impact on the tree’s stability, health and hazard potential—especially if other defects are noted such as cracks, rot, or root defects. 9) FOLIAGE/BRANCH—describes the foliage of the tree in relation to a perfect specimen of that particular species. First the branch growth and foliage density is described, and then any signs or symptoms of stress and/or disease are noted. The condition of the foliage, or the branches and buds for deciduous trees in the dormant season, are important indications of a tree’s health and vigor. i) For Deciduous trees in the dormant season: (1) The structure of the deciduous tree is visible. (2) The quantity and quality of buds indicates health, and is described as good bud set, average bud set, or poor bud set. These are abbreviated in the spreadsheet as: gbs, abs, or pbs. (3) The amount of annual shoot elongation is visible and is another major indication of tree health and vigor. This is described as: a) Excellent, Good, Average, or Short Shoot Elongation. These are abbreviated in the spreadsheet as ESE, GSE, ASE, or SSE. ii) For evergreen trees year round and deciduous trees in leaf, the color and density of the foliage indicates if the tree is healthy or stressed, or if an insect infestation, a bacterial, fungal, or viral infection is present. Foliage is categorized on a scale from: (1) Dense—extremely thick foliage, an indication of healthy vigorous growth, (2) Good—thick foliage, thicker than average for the species, (3) Normal/Average—thick foliage, average for the species, an indication of healthy growth, (4) Thin or Thinning—needles and leaves becoming less dense so that sunlight readily passes through; an indication that the tree is under serious stress that could impact the long-term survivability and safety of the tree, (5) Sparse—few leaves or needles on the twigs, an indication that the tree is under extreme stress and could indicate the future death of the tree, Evaluation of Trees at 1601 Lind Avenue, Renton, WA 98057 Gilles Consulting April 22, 2015 Page 32 of 39 (6) Necrosis—the presence of dead twigs and branchlets. This is another significant indication of tree health. A few dead twigs and branches are reasonably typical in most trees of size. However, if there are dead twigs and branchlets all over a certain portion of the tree, or all over the tree, these are indications of stress or attack that can have an impact on the tree’s long-term health. (7) Hangers—a term to describe a large branch or limb that has broken off but is still hanging up in the tree. These can be particularly dangerous in adverse weather conditions. 10) CROWN CONDITION—the crown is uppermost portion of the tree, generally considered the top 10 to 20% of the canopy or that part of the canopy above the main trunk in deciduous trees and above the secondary bark in evergreen trees. i) The condition of the tree’s crown is a reflection of the overall health and vigor of the entire tree. The crown is one of the first places a tree will demonstrate stress and pathogenic attack such as root rot. ii) If the Crown Condition is healthy and strong, this is a good sign. If the crown condition is weak, broken out, or shows other signs of decline, it is an indication that the tree is under stress. It is such an important indication of health and vigor that this is the first place a trained forester or arborist looks to begin the evaluation of a tree. Current research reveals that, by the time trees with root rot show significant signs of decline in the crown, fully 50% or more of the roots have already rotted away. Crown Condition can be described as: (1) Healthy Crown—exceptional growth for the species. (2) Average Crown—typical for the species. (3) Weak Crown—thin spindly growth with thin or sparse needles. (4) Flagging Crown—describes a tree crown that is weak and unable to grow straight up. (5) Dying Crown—describes obvious decline that is nearing death. (6) Dead Crown—the crown has died due to pathological or physical injury. The tree is considered to have significant stress and/or weakness if the crown is dead. (7) Broken out—a formerly weak crown condition that has been broken off by adverse weather conditions or other mechanical means. (8) Regenerated or Regenerating—formerly broken out crowns that are now growing back. Regenerating crowns may appear healthy, average, or weak and indicate current health of the tree. (9) Suppressed—a term used to describe poor condition of an entire tree or just the crown. Suppressed crowns are those that are entirely below the general level of the canopy of surrounding trees which receive no direct sunlight. They are generally in poor health and vigor. Suppressed trees are generally trees that are smaller and growing in the shade of larger trees around them. They generally have thin or sparse needles, weak or missing crowns, and are prone to insect attack as well as bacterial and fungal infections.

Typical things noted are: i) FORKED—bifurcation of branches or trunks that often occur at a narrow angle. ii) INCLUDED BARK—a pattern of development at branch or trunk junctions where bark is turned inward rather than pushed out. This can be a serious structural defect in a tree that can and often does lead to failure of one or more of the branches or trunks, especially during severe, adverse weather conditions. iii) EPICORMIC GROWTH—this is generally seen as dense thick growth near the trunk of a tree. Although this looks like a healthy condition, it is, in fact the opposite. Trees with Epicormic Growth have used their reserve stores of energy in a last ditch effort to produce enough additional photosynthetic surface area to produce more sugars, starches and carbohydrates to support the continued growth of the tree. Generally speaking, when conifers in the Pacific Northwest exhibit heavy amounts of Epicormic Growth, they are not producing enough food to support their current mass and are already in serious decline. iv) INTERNAL STRUCTURAL WEAKNESS—a physical characteristic of the tree trunk, such as a kink, crack, rot pocket, or rot column that predisposes the tree trunk to failure at the point of greatest weakness. v) BOWED—a gradual curve of the trunk. This can indicate an Internal Structural Weakness or an overall weak tree. It can also indicate slow movement of soils or historic damage of the tree that has been corrected by the curved growth. vi) KINKED—a sharp angle in the tree trunk that indicates that the normal growth pattern is disrupted. Generally this means that the internal fibers and annual rings are weaker than straight trunks and prone to failure, especially in adverse weather conditions. vii) GROUND FLOWER—an area of deformed bark near the base of a tree trunk that indicates long-term root rot. 12) ROOT COLLAR—this is the area where the trunk enters the soil and the buttress roots flare out away from the trunk into the soil. It is here that signs of rot, decay, insect infestation, or fungal or bacterial infection are noted. NAD stands for No Apparent Defects. 13) ROOTS—any abnormalities such as girdling roots, roots that wrap around the tree itself that strangle the cambium layer and kill the tree, are noted here. 14) COMMENTS—this is the area to note any additional information that would not fit in the previous boxes or attributes about the tree that have bearing on the health and structure of the tree. 15) CURRENT HEALTH RATING—A description of the tree’s general health ranging from dead, dying, poor, senescent, suppressed, fair, good, very good, to excellent. 16) RECOMMENDATION— this is an estimate of whether or not the tree is of sufficient health, vigor, and structure that it is worth retaining. Specific Evaluation of Trees at 1601 Lind Avenue, Renton, WA 98057 Gilles Consulting April 22, 2015 Page 34 of 39 recommendations for each tree are included in this column. They may include anything from pruning dead wood, mulching, aerating, injecting tree-based fertilizer into the root system, shortening into a habitat tree or wildlife snag, or to completely removing the tree. i) Monitor: “Monitor” is a specific recommendation that the tree be re- evaluated on a routine basis to determine if there are any significant changes in health or structural stability. “Monitor annually” (or bi-annually, tri- annually, etc.)” means the tree should be looked at once every year (or every 2 or 3 years, etc.) This yearly monitoring can be a quick look at the trees to see if there are any significant changes. Significant changes such as storm damage, loss of crown, partial failure of one or more roots, etc. require that a full evaluation be done of the tree at that time. ii) Potential to retain with tree protection measures: means that the tree appears to have the internal resources, the health and vigor, structural stability, and the wind firmness to be able to withstand the stresses of construction if development requirements and construction requirements allow. iii) Habitat or Remove: means that the tree has a high potential to fail and cause either personal injury or property damage—in other words the tree has been declared a hazard tree and should be dealt with prior to the next large storm. If it is at all possible the recommendation is to leave some of the trunk standing for wildlife habitat and some of the trunk on the ground as a nurse log. The height of the standing habitat tree depends upon the size of the tree, the condition of the tree, and the distance to a probable target. It should be short enough so that when it does fail years in the future it will not cause personal injury or property damage. Nurse logs can be laid horizontally across the slope to aid with erosion control and to provide microenvironments for new plantings. The nurse logs meaning to be steak to prevent their movement and potential harm to people. If for some reason this is not possible that should be removed for safety. NOTE: TREES WITH THE SAME DESCRIPTION AND DIFFERENT RATINGS: Two trees may have the same descriptions in the matrix boxes, one may be marked “Significant,” while another may be marked “Non-Significant.” The difference is in the degree of the description, i.e., “early necrosis” versus “advanced necrosis” for instance. Another example is “center rot” or ‘base rot”. In a Western Red Cedar tree, the presence of low or even moderate rot is not significant and does not diminish the strength of the tree. However, low levels of rot in the base of a Douglas Fir tree, in an area known to have virulent pathogens present, is highly significant and predisposes that tree to windthrow.

If tree protection is not planned integral with the design and layout of the project, the trees will suffer needlessly and will possibly die. With proper preparation, often costing little, or nothing extra to the project budget, trees can survive and thrive after construction. This is critical for tree survival because damage prevention is the single most effective treatment for trees on construction sites. Once trees are damaged, the treatment options available are limited. The following minimum Tree Protection Measures are included on three separate sheets so that they can be copied and introduced into all relevant documents such as site plans, permit applications and conditions of approval, and bid documents so that everyone involved is aware of the requirements. These Tree Protection Measures are intended to be generic in nature. They will need to be adjusted to the specific circumstances of your site that takes into account the location of improvements and the locations of the trees.

Tree Protection Fences will need to be placed around each tree or group of trees to be retained. a. Tree Protection Fences are to be placed according to the attached drawing at a distance of not less than 5 feet outside the dripline of the tree or group of trees to be saved. b. Tree Protection Fences must be inspected prior to the beginning of any demolition or construction work activities. c. Nothing must be parked or stored within the Tree Protection Fences—no equipment, vehicles, soil, debris, or construction supplies of any sorts. 2. Cement trucks must not be allowed to deposit waste or wash out materials from their trucks within the Tree Protection Fences. 3. The Tree Protection Fences need to be clearly marked with the following or similar text in four inch or larger letters: “TREE PROTECTION FENCE DO NOT ENTER THIS AREA DO NOT PARK OR STORE MATERIALS WITHIN THE PROTECTION AREA Any questions, call City of Renton, Development Services-Code Compliance at (425)430-7373. 4. The area within the Tree Protection Fencing must be covered with wood chips, hog fuel, or similar materials to a depth of 8 to 10 inches. The materials should be placed prior to beginning construction and remain until the Tree Protection Fencing is taken down. 5. When excavation occurs near trees that are scheduled for retention, the following procedure must be followed to protect the long term survivability of the tree: a. An International Society of Arboriculture, (ISA) Certified Arborist must be working with all equipment operators. i. The Certified Arborist should be outfitted with a shovel, hand pruners, a pair of loppers, a handsaw, and a power saw (a “sawsall” is recommended). b. The hoe must be placed to “comb” the material directly away from the trunk as opposed to cutting across the roots. i. Combing is the gradual excavation of the ground cover plants and soil in depths that only extend as deep as the tines of the hoe.

When any roots of one inch diameter or greater, of the tree to be retained, is struck by the equipment, the Certified Arborist should stop the equipment operator. d. The Certified Arborist should then excavate around the tree root by hand/shovel and cleanly cut the tree root. i. The Certified Arborist should then instruct the equipment operator to continue. 6. Putting Utilities Under the Root Zone: a. Boring under the root systems of trees (and other vegetation) shall be done under the supervision of an ISA Certified Arborist. This is to be accomplished by excavating a limited trench or pit on each side of the critical root zone of the tree and then hand digging or pushing the pipe through the soil under the tree. The closest pit walls shall be a minimum of 7 feet from the center of the tree and shall be sufficient depth to lay the pipe at the grade as shown on the plan and profile. b. Tunneling under the roots of trees shall be done under the supervision of an ISA Certified Arborist in an open trench by carefully excavating and hand digging around areas where large roots are exposed. No roots 1 inch in diameter or larger shall be cut. c. The contractor shall verify the vertical and horizontal location of existing utilities to avoid conflicts and maintain minimum clearances; adjustment shall be made to the grade of the new utility as required. 7. Watering: a. The trees will require significant watering throughout the summer and early fall in order to survive long-term. An easy and economical watering can be done using soaker hoses placed three feet from the trunk of the tree and spiraled around the tree. One 75-foot soaker hose per tree is adequate. It is best to place the soakers using landscape staples, (available from HD Fowler in Bellevue for pennies apiece) then cover the area with two to three inches composed materials. The composted material will act as a mulch to minimize evaporation and will also stimulate the microbial activity of the soil which is another benefit to the health of the tree. b. Water the tree to a depth of 18 to 20 inches. I recommended leaving the water on the soaker hoses for six to eight hours and then digging down to determine how deep your water is penetrating. Then adjust accordingly. It may take a good two days of watering to reach the proper depth. c. Once the water reaches the proper depth, turn off the hoses for four weeks and then water again. Water more often when temperatures increase— every three weeks when temperatures exceed 80 degrees and every two weeks when temperatures exceed 90 degrees. This drying out of the soil in between watering is important to prevent soil pathogens from attacking the trees.
