Mill Creek, WA. 98037 o f 9. l e l e l s 215TH PL SW J D 218TH ST SW 9 LtL!_-:q d Eq ..,,t 8 Page I of 4 File No. PLN2022-0050 Golden Leaves Condominium Landscaping Revision Administrative Design Review The subject site is located within the Multi -Family Residential, RM-2.4, zone (see inset - zoning map). As such, the proposal is subject to the General Design Review requirements of ECDC Chapter 20.11. Pursuant to ECDC 20.11.010, since the proposal does not require a SEPA threshold determination, staff may review the proposal as an administrative Type I decision, subject to the requirements of ECDC 20.01 and 20.02. The applicant submitted a land use application (Attachment 1), cover letter (Attachment 2), arborist report (Attachment 4) and a revised landscape plan (Attachment 3). The application became procedurally complete pursuant to ECDC 20.02.002 on August 8, 2022, (Attachment 5). On August 8, 2022, a letter requesting additional information was sent to the applicant (Attachment 5), and on August 16, 2022, the applicant submitted a revised landscape plan (Attachment 3). C. Criteria and Comprehensive Plan Compliance The subject site is located within the "Mixed Use Commercial" designation of the Comprehensive Plan. Nothing in this proposal appears to be in conflict with the goals and policies of the Comprehensive Plan. D. Technical Review The Engineering Division has reviewed the subject application and found the proposal to be consistent with Title 18 Edmonds Community Development Code and Engineering standards. Requested conditions of approval have been added to the decision (Attachment 6). E. Public Comments Pursuant to ECDC 20.01.003(C), public notice is not required for Type I decisions. Thus, public notice was not required for the subject application. As such, no public comments have been received in response to the proposal. F. Findinzs and Conclusions a. The subject site is located within the Multi -Family Residential, RM-2.4 zone. The properties located to the north, east and south are also in the RM-2.4 zone. To the west of the subject property is 80th Ave. W., the properties located on the west side of 80th Ave. W. are zoned Single -Family Residential, RS-8. Properties surrounding the subject site are primarily developed with residential uses. b. Current landscaping requirements are contained within ECDC Chapter 20.13. Although the current landscaping requirements are different from the landscaping requirements that may have been in place at the time of original development of the site, any proposed changes to existing landscaping are subject to the current code requirements of ECDC 20.13. Thus, any proposed changes to existing landscaping must strive towards bringing the site closer into compliance with current landscaping requirements. c. The proposal includes the removal of three trees, two trees are fronting off 801h Ave. W. and one tree is located within the parking lot as shown in attachment 3. Per the cover letter and arborist report the trees are exhibiting hazards and have outgrown their space (Attachment 2 & 4). Page 2 of 4 File No. PLN2022-0050 Golden Leaves Condominium Landscaping Revision Administrative Design Review d. In accordance with ECDC 20.13.030, Type V landscaping is appropriate in the vicinity of the parking lot (Tree #7202). Type V landscaping is intended to provide visual relief and shade in parking areas. e. In accordance with ECDC 20.13.030, Type IV landscaping is appropriate in the vicinity of the street frontage along 80th Ave. W. (Trees #7201 & 7203). Type IV landscaping is intended to provide visual relief where clear sight is desired to see signage or into adjacent space for safety concerns. f. In order to comply with the landscape requirements, the applicant has proposed relace each tree with a 2-inch Maple Tree. Additionally, in the vicinity of the parking lot tree (Tree #7202), five evergreen huckleberry, nine ferns and three red twig dogwoods will be installed. All new plants are proposed to be planted in fresh soil and topped with fresh mulch (Attachment 3). g. Minimum sizes of plants at installation are provided within ECDC 20.13.015. This requirement has been added within the conditions of approval. G.

Edmods Wa Remove Three trees Marked 7201 Eastern white Pine Tree #7201 is more likely to experience branch failures rather than a whole tree failure. Pruning of dead branches is encouraged in order to limit the amount of risk the tree poses to pedestrians. Otherwise, retain the tree and monitor the overall health of the tree every year. The tree should be removed if the trunk or root collar shows signs of decay. 7202 Knobcone Pine Tree #7202 shows signs of uplifting and should be removed before whole tree failure occurs. The loose soil around and under the roots of the tree indicates that the stability of the tree is in jeopardy. The upheaving of soil is occurring on the northwest side and indicates that the tree is actively leaning to the southeast toward the apartment building. 7203 American Beech Tree #7203 is in fair condition. It is unlikely that the roots have recently encroached the building's foundation, as it is a large and established tree that likely has roots existing below the foundation. Employing an ISA-certified arborist to perform a Leve13 Advanced Assessment may yield a better understanding of the current root structure.

March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 2 of 19 Introduction Davey Resource Group Inc. (DRG) was contracted by John Miranda, owner of Premiere Lawn Service Inc., to perform a Level 2 Tree Risk Assessment on three (3) trees on the property at 21615 80th Ave W, Edmonds, Washington. The trees are located at The Golden Leaves (Parcel Number: 00679800010100) and are being assessed for safety hazards that the trees may pose to the residents of the community. On March 14, 2022, an International Society of Arboriculture (ISA) Certified Arborist (WE-11849AU) and Qualified Tree Risk Assessor from DRG conducted an assessment of the trees. The trees were assessed by their location, size, current condition, and overall health. The data was then used to determine a risk rating. The current edition of the Tree Risk Assessment Manual (ISA, 2013) was used to guide the risk rating of the trees, as well as, the potential strategies for care and risk abatement. The purpose of this report is to provide the details of the risk assessment of the trees, including an assessment of the current condition, health, and recommendations for maintenance. The findings in this report can be used to decide whether the tree may need to be removed, or retained with restorative pruning and plant health care. Methods Data was collected by an ISA Certified Arborist (Marc Leonard - WE-11849AU) on March 14, 2022. A visual inspection was used to develop the findings, conclusions, and recommendations found in this report. No physical inspection of the upper canopy, root crown excavation, use of a resistograph, or other technologies were used in the evaluation of the trees. The following attributes were collected for each site: Condition: Condition ratings were based on but not limited to:(1) the condition and environment of the tree's root crown; (2) the condition of the trunk, including decay, injury, callusing, or presence of fungus sporophore; (3) the condition of the limbs, including the strength of crotches, amount of deadwood, hollow areas, and whether there was excessive weight borne by them; (4) the condition and growth rate history of the twigs, including pest damage and diseases; (5) the leaf appearance, including abnormal size and density as well as pest and disease damage. Using an average of the above factors together with the arborist's best judgment, the general condition of the tree was recorded in one of the following categories adapted from the rating system established by the International Society of Arboriculture: • Good: A fully branched and leafed canopy; branches over 2 inches in diameter exhibit little to no dieback; little to no epicormic growth (i.e., sprouting from the trunk, limbs, or roots); and little to no aesthetic damage from insects or disease. The tree displays a growth habit characteristic of the species. The wood has no major structural problems and no significant mechanical damage. The tree exhibits good overall vigor. • Fair: The canopy is thinning and there is less than average new growth present, or there is noticeable dead wood over 2" diameter or dieback throughout the majority of the crown, or there is significant mechanical damage to the trunk or root system, or the tree is otherwise exhibiting significant signs of stress and potential decline. The following signs or symptoms may be present in the tree: significant damage from non -fatal or disfiguring diseases, minor crown imbalance or Prepared by: DRG Inc. March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 3 of 19 thin crown, and/or stunted growth compared to adjacent trees. This condition also includes trees that have been topped but show reasonable vitality and no obvious signs of decay. • Poor: The tree is in obvious decline or poses a significant risk that requires immediate mitigation. There are significant amounts of dieback or dead/dying limbs greater than 2" in diameter; there is minimal to no growth; or there is extensive decay to the trunk or root system, raising concerns of structural integrity. A tree in this category may also have severe mechanical damage or poor vigor threatening its ability to thrive. • Critical: The tree is dying and/or presents an unacceptable risk that necessitates immediate removal. • Dead Tree Number: The tree ID number was assigned. Stems: The number of stems was recorded. Location and Unique ID: An X and Y coordinate was generated for each tree site. Species: Trees were identified by genus and species, cultivar if evident, and by common name. Diameter at Breast Height (DBH): Trunk diameter was recorded to the nearest inch at 4.5 feet (standard height) above grade except where noted. When limbs or deformities occurred at standard height, measurement was taken below 4.5 ft. The DBH of multi -trunk trees was determined by taking the square root of the sum of the DBH for each stem squared (per the City of Seattle method). Height: Tree Height estimated to the nearest <5ft. Avg. Canopy Radius: Average dripline distance was measured. Limits of the Assignment There are many factors that can limit specific and accurate data when performing evaluations of trees, their conditions, and values. The determinations and recommendations presented here are based on current data and conditions that existed at the time of the evaluation and cannot be a predictor of the ultimate outcomes for the trees. A visual inspection was used to develop the findings, conclusions, and recommendations found in this report. Values were assigned to grade the attributes of the trees, including structure and canopy health, and to obtain an overall condition rating. No physical inspection of the upper canopy, root crown excavation, resistograph, or other technologies, were used in the evaluation of the trees. Prepared by: DRG Inc. March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 4 of 19 Risk Assessment Methodology This evaluation follows the tree risk assessment methods developed by the International Society of Arboriculture (ISA). It consists of an inspection of the visible tree parts including surface roots, trunk, scaffold limbs, and canopy. The hazard and risk assessment results in a risk rating for the tree to help quantify the level of risk accepted by the tree's owner. To summarize the information about the trees that received a hazard evaluation, an overall hazard rating is obtained by assessing and assigning a value to the failure potential, identifying the size of the tree part most likely to fail (e.g., branch, one stem, or whole tree) and determining site use around the affected tree. Each of these three characteristics is assessed as follows: Condition of Concern — Describes the part most likely to fail. The larger the tree part, the greater the potential for damage; therefore, the size of the failure part affects the overall hazard potential, and is described according to: • Part Size - Typically the diameter of the limb or tree part • Fall Distance - The distance of the part from the ground • Target - The presence of any target(s) that could be impacted by a failure Likelihood of Failure — Identifies the most likely point of failure and rates the likelihood that the observed defect(s) will result in part failure within the next 3 years. Failure potential is rated as: • Improbable (defects are minor and unlikely to result in failure) • Possible (defects are present and of concern) • Probable (compounding and/or significant defects present) • Imminent (defects are serious and imminent failure is likely) Likelihood of Impact — Identifies the most likely point of failure and rates the likelihood that the structural defect(s) will impact the potential targets. Likelihood of impact is rated as: • Very Low (Occasional use, as in a forest landscape) • Low (e.g., tree lawn, sidewalk, park path) • Medium (buildings or people within striking range more than 50% of the time) • High (Constant and frequent use of the area within striking distance) Consequences of Failure — Rates the level of damage caused by the defective part in the event of failure. The consequences of failure are rated as: • Negligible (typically small branches <1" diameter, unlikely to cause damage) • Minor (branches 1-2" diameter, may cause damage) • Significant (damage would occur) • Severe (failure would result in major damage) Overall Risk Rating - The values assigned to condition, likelihood, and consequences are summarized into an overall risk rating of Low to Extreme for each tree: • Low (risk is present, mitigation measures may not be required) • Moderate (mitigation advised within normal maintenance cycle) • High (mitigation advised within the year) • Extreme (mitigation necessary as soon as practical) Prepared by: DRG Inc. March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 5 of 19 In addition to a risk rating, the tree was also prescribed maintenance recommendations based on general tree health and visual observations. A high -risk rating alone does not necessarily result in a removal recommendation. Conversely, trees with a lower rating may be prescribed for removal based on other factors such as location and species compatibility and/or the severity of specific defects. Whenever recommended tree maintenance would mitigate risk, the residual risk was also noted. A visual inspection and mallet soundings from groundline to 8 feet on the trunk were the primary methods used to develop the findings, conclusions, and recommendations found in this report. Data collection included measuring the diameter of the tree at 4.5 feet above grade, height estimation, canopy radius estimation, a visual assessment of tree condition, structure, and health, and a photographic record. Mallet sounding was used to determine the soundness of accessible roots, the trunk, and branches. Example Illustration: Tree defects and conditions affecting the likelihood of failure were assessed around the Root Collar, the Trunk, and the Crown Prepared by: DRG Inc. March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 6 of 19 Tree Risk Assessment Tree #7201 - Eastern white pine (Pinus strobus) The tree is growing on the far northwest corner of the property at 80th Ave W with overhead utilities present. Crown and Branches - The live crown ratio is roughly 50% with a large portion of the canopy no longer being present. The tree has been pruned (`topped') in order to maintain a safe clearance for the utility lines overhead. Profuse amounts of pitch are presently secreting from the pruning wound site. Few branches have desiccated while other branches show signs of dieback. Trunk - The trunk shows signs of excessive pitch dripping down the trunk of the tree. There are no signs of rot or decay on the trunk. Mallet sounding did not indicate the presence of internal decay. Roots and Root Collar - The tree is growing in a confined planting strip. The root collar is partially exposed. Exposed roots indicate minor girdling. No mushroom or decay fungi were observed. Heaving is occurring at the sidewalk to the west of the tree and at parking pavers to the south of the tree. Risk Categorization The likelihood of the whole tree within the next 3 years is improbable with a high risk of impacting the safety of pedestrians and vehicle drivers. This event is somewhat likely and the consequences of impact are significant. Overall Tree Risk Rating: Low Mitigation Options Retain and monitor or remove the tree. Prepared by: DRG Inc. March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 7 of 19 Tree Risk Assessment Tree #7202 - Knobcone pine (Pinus attenuata) 22 55 20 Fair The tree growing in a landscape planting bed of the parking lot on the northwest portion of the property. Crown and Branches - The live crown ratio is roughly 85% with a majority of the crown in good vigor. The tree has an average canopy radius of 20 feet. There are three codominant stems that originate 30 feet up the tree. Visible pitch and included bark at the union of the three stems are present. Trunk - Multiple pruning sites exist on the trunk. There are no signs of rot or decay on the trunk. Mallet sounding did not indicate the presence of internal decay. Roots and Root Collar - Roots of varying sizes are exposed at the ground level on the northwest side of the tree. The largest of the exposed roots sits an inch above ground with signs of recent uplifting. A small cavity in the ground exists below the trunk of the tree and reaches more than 2 feet below the ground's surface. The soil in and around the cavity felt loose. The roots of the tree are heaving the parking lot pavement and pavers. No mushroom or decay fungi were observed. Risk Categorization The likelihood of the tree failing into the building within the next 3 years is imminent with a medium risk of impacting the safety of pedestrians and vehicle drivers. This event is very likely and the consequences of impact are severe. Overall Tree Risk Rating: Extreme Mitigation Options Removal of the tree. Prepared by: DRG Inc. March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 8 of 19 Tree Risk Assessment Tree #7203 - American beech (Fagus grandifolia) The tree is growing on the west side of a building structure on 80th Ave W with overhead utilities present. Crown and Branches - The live crown ratio is roughly 70% with a majority of the crown in good vigor. The tree has an average canopy radius of 25 feet. The large branches (roughly 16 inches in diameter) that begin to grow about 10 feet up the tree have impacted each other. Routine utility pruning has taken place on the west side of the crown. Trunk - The trunk is within 5 feet of the adjacent building structure. There are no signs of rot or decay on the trunk. Mallet sounding did not indicate the presence of internal decay. Roots and Root Collar - The root collar is exposed. Buttress roots are exposed and grow in all directions from the trunk. Root growth has cracked the nearby asphalt and appears to be advancing toward the foundation of the building. No mushroom or decay fungi were observed. Risk Categorization The likelihood of the tree growing into the building within the next 3 years is probable with a high risk of impacting the building structure. This event is somewhat likely and the consequences of impact are significant. Overall Tree Risk Ratina: Moderate Mitigation Options Retain and monitor the tree or remove the tree. Prepared by: DRG Inc. March 2022 Prepared for: Premiere Lawn Service Inc. - 21615 80th Ave W Page 9 of 19 Recommendations The following options are presented in order of priority of each tree. Tree #7201: Option #1 - Remove the tree and all tree parts. Option #2 - Retain and monitor the tree. Re -inspect in 3 years. Tree #7202: Option #1 - Remove the tree and all tree parts. Option #2 - Retain and monitor the tree. Re -inspect in 3 years. Tree #7203: Option #1 - Remove the tree and all tree parts. Option #2 - Retain and monitor the tree. Re -inspect in 3 years. Concluding Remarks Tree #7201 is more likely to experience branch failures rather than a whole tree failure. Pruning of dead branches is encouraged in order to limit the amount of risk the tree poses to pedestrians. Otherwise, retain the tree and monitor the overall health of the tree every year. The tree should be removed if the trunk or root collar shows signs of decay. Tree #7202 shows signs of uplifting and should be removed before whole tree failure occurs. The loose soil around and under the roots of the tree indicates that the stability of the tree is in jeopardy. The upheaving of soil is occurring on the northwest side and indicates that the tree is actively leaning to the southeast toward the apartment building. Tree #7202 is in fair condition. It is unlikely that the roots have recently encroached the building's foundation, as it is a large and established tree that likely has roots existing below the foundation. Employing an ISA-certified arborist to perform a Level3 Advanced Assessment may yield a better understanding of the current root structure. Ground -penetrating radar can be used to determine the extent of the root growth and indicate any damage to the building's foundation. Prepared by: DRG Inc.
