On Tuesday, January 3rd, I walked the site to inspect the trees and document my findings. A summary, tree table, site map, and photographic documentation can be found below under sections 1 - 4. Where applicable, I have categorized risk based on the methodologies presented in the International Society of Arboriculture’s Tree Risk Assessment (Best Management Practices). My responsibilities were to provide the following: A tree plan that includes a tree inventory, site map, replanting information (if necessary), tree protection measures for on-site and off-site trees (where CRZ extends on-site) (if requested), and recommendations that will meet the minimum city of Renton tree code requirements. Site Description This 16,015 square foot lot is located on the north-west corner of NE 16th Street and Index Ave NE. The topography of the site gently slopes from east to west. According to the City of Renton GIS data, there are no environmentally critical areas. The property is mostly clear of vegetation, with the exception of a small planter bed near the existing home and a few small native conifers south and east of the home. Subject Trees – Three (3) significant trees.

Summary This report is preliminary as I have not reviewed any design plans or construction details for the site. Tree locations are approximations based on KC Parcel Viewer data and conditions observed during my site visit. • Three (3) significant, but not landmark trees, were located on-site. The trees are currently in good condition and viable for retention. One of these trees may be located at least partially within the ROW. • Per RMC 4-8-120, 30% of all significant on-site trees must be retained. • Lots are required to provide a minimum tree density of 30 tree credits per net acre. The lot is 16,015 square feet (.37 acres) and will require 11 tree credits. Retained trees will require protection measures to ensure they are not significantly impacted by construction. Renton tree protection measures, fencing details, and ISA recommended tree protection guidelines can be found below under sections 7 – 9.

Details of Risk Assessment Level 2: Basic Assessment A level 2 basic assessment is the standard assessment performed for tree risk. The assessment includes a detailed visual inspection of a tree and its surrounding site, and a synthesis of the information collected. The basic assessment involves walking completely around the tree – looking at the site, buttress roots, trunk, and branches. The tree is viewed from a distance, as well as close up, to consider crown shape and surroundings. Methodology – When identifying potential hazard trees, I must consider a variety of factors that could contribute to failure. This can include the following: previous history of site failures, topography, site changes, prevailing wind direction and exposure, tree size and species, growth habit, overall vigor, the density and health of the foliage and crown, examination of root and root collar health, dead wood, hanging or broken branches, and evidence of disease-causing bacteria, fungi, or virus. Tools Utilized: Binoculars, compass, hammer, diameter tape, clinometer, camera, soil probe. Timeline – This assessment covers a five-year period and is based on conditions present at the time of the assessment. 5. Definitions: DSH - Tree size is measured in Diameter at Standard Height (DBH) – standard forestry methodology for measuring tree size. Multi-stemmed trunk combined DBH determined by the square root of the sum of all squared trunk stems DBH. Renton “Significant Tree” – “greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods” Renton “Landmark Tree” – “a tree 24 inches in diameter (DBH) or greater.” Driplines – Most trees in groves do not have symmetrical driplines. Therefore, drip line radius was measured in the quadrant assumed to be most affected by future disturbance or where most significant. Inner root zone – “means an area encircling the base of a tree equal to one-half (½) the diameter of the drip line.” Risk – The combination of the likelihood of an event and the severity of the potential consequences. In the context of trees, risk is the likelihood of a conflict or a tree failure occurring and affecting a target, and the severity of the associated consequences – personal injury, property damage, or disruption of activities. How people perceive risk and their need for personal safety is inherently subjective; therefore, risk tolerance and action thresholds vary. What is within the tolerance of one person may be unacceptable to another. It is impossible to maintain trees completely free of risk—some level of risk must be accepted to experience the benefits that trees provide.

Poor – A tree described with a poor condition would have a combination of the following features: low vigor, sparse crown density, and few interior branches. The crown could be unbalanced or contain many dead twigs/branches. It may also have been topped, tipped, or mal pruned. The trunk could have cracks, cavities, conks/mushrooms, and evidence of decay within the tree. Fair – A fair description would describe a tree with normal vigor and crown density. The tree may possess one or possibly two of the above listed qualities but overall is in decent health. Improvements of site conditions could improve the trees health. Good – Trees listed in good condition will have high vigor with a thick crown density. It would have few, if any defects, and would be a good example of that specific tree. Explanation of Risk Ratings as Defined by the ISA. Low – The low-risk category applies when consequences are negligible, and likelihood is unlikely; or consequences are minor, and likelihood is somewhat likely. Moderate – Moderate-risk situations are those for which consequences are minor and likelihood is very likely or likely; or likelihood is somewhat likely, and consequences are significant or severe. High – High-risk situations are those for which consequences are significant and likelihood is very likely or likely, or consequences are severe, and likelihood is likely. Extreme – The extreme-risk category applies in situations in which failure is imminent, there is a high likelihood of impacting the target, and the consequences of the failure are severe DocuSign Envelope ID: A5115E6D-5FF1-4242-8D6A-1BDF53158A96 Page 7 of 16 Arborist Report - Encompass ES - 1711 Index Avenue NE TREE FROG LLC https://www.treefrogllc.com/ PO Box 307, Duvall, WA 98019 [P] 206-310-8254 [E] andycrossett@hotmail.com 6.

ISA Recommended Tree Protection Information The Pacific Northwest Chapter of the ISA Recommends the following for protecting trees from damage during construction. https://pnwisa.org/tree-care/damage/protecting-trees-from-damage/ “Critical Root Zone Protection A critical step in retaining healthy trees is the protection of tree roots from disturbance. Each tree has a critical root zone (CRZ) that varies by species and site conditions. The International Society of Arboriculture defines CRZ as an area equal to a 1-foot radius from the base of the tree’s trunk for each 1 inch of the tree’s diameter at 4.5 feet above grade (referred to as diameter at breast height). Another common rule of thumb is to use a tree’s drip line to estimate the CRZ (see figure). Evaluate both of these and choose whichever provides the larger CRZ. Under certain circumstances, disturbing or cutting roots in a CRZ may be unavoidable. In such cases, the work should be done only under the on-site supervision of an ISA Certified Arborist. Cutting or disturbing a large percentage of a tree’s roots increases the likelihood of the tree’s failure or death. Never cut tree roots that are more than four inches wide; roots that large are usually structural. Cutting them can destroy the stability of the tree, causing it to fall over! If you must cut tree roots, do so cleanly with sharp tools. Never tear with a backhoe or other dull instrument. A clean cut encourages good wound closure and confines the spread of decay. If damage is severe, consider removing the tree because its stability may have been compromised. Activities to Avoid in the Critical Root Zone The CRZ that should be protected from negative interactions. Avoid the following activities: • Stockpiling construction materials or demolition debris • Parking vehicles or equipment • Piling soil and/or mulch • Trenching for utilities installation or repair, or for irrigation system installation • Changing soil grade by cutting or filling • Damaging roots by grading, tearing, or grubbing • Compacting soil with equipment, vehicles, material storage, and/or foot traffic DocuSign Envelope ID: A5115E6D-5FF1-4242-8D6A-1BDF53158A96 Page 10 of 16 Arborist Report - Encompass ES - 1711 Index Avenue NE TREE FROG LLC https://www.treefrogllc.com/ PO Box 307, Duvall, WA 98019 [P] 206-310-8254 [E] andycrossett@hotmail.com • Contaminating soil from washing out equipment (especially concrete) and vehicle maintenance • Installing impervious parking lots, driveways, and walkways • Attaching anything to trees using nails, screws, or spikes • Wounding or breaking tree trunks or branches through contact with vehicles and heavy equipment • Wounding trunks with string weed trimmers and lawn mowers • Causing injury by fire or excessive heat During Construction Monitor compliance with tree protection requirements and the impacts of construction activities on tree health regularly during construction. If there are incursions into the root zone, ensure roots have been severed cleanly, enforce penalties, and reestablish the protection zone. Confer with your contractors to make sure that construction offices, vehicular parking, worker break sites, concrete washout areas or other pollutants, and material storage will remain outside of protected areas. Diligence in maintaining barriers and in enforcing your protection plan will pay great dividends at the end of the project when the tree is still healthy. Following the guidelines laid out above will serve in most situations, but occasionally construction plans will require impingement on the CRZ. Trenching Trenching is a standard way to install utilities. It is best to entirely avoid trenching through the CRZ (see figure); such practice could severely destabilize a tree, as well as adversely affect its health through loss of roots. Workers performing such operations should understand that 85% of the mass of a tree’s root system is located within the CRZ and that most of a tree’s roots are within the top 18 inches of soil. Alter routes of underground infrastructure or use alternate methods such as pipe boring. Tunneling at least 18 inches beneath the root zone will prevent loss of critical root mass if underground utilities must unavoidably be placed within the CRZ. A decision must be made as to where best to locate utility trenches. Planners and designers must be made aware that trenches may not cross a CRZ and design alternate alignments accordingly; such realignments are not the responsibility of the construction crew. Best practices for trenching include the following: • Protect the trunks of high-value trees from scraping and gouging to a height of at least eight feet. • Keep equipment and excavated backfill on the side furthest from the tree, not against the trunk. DocuSign Envelope ID: A5115E6D-5FF1-4242-8D6A-1BDF53158A96 Page 11 of 16 Arborist Report - Encompass ES - 1711 Index Avenue NE TREE FROG LLC https://www.treefrogllc.com/ PO Box 307, Duvall, WA 98019 [P] 206-310-8254 [E] andycrossett@hotmail.com • Place excavated backfill on a plastic or canvas tarp outside the CRZ. • Prune away jagged roots back to the trench wall closest to the tree. Use a handheld pruner or pruning saw to make sharp, clean cuts. • Replace the backfill on the same day if at all possible. Cover exposed roots with wet burlap to prevent them from drying out; in hot dry conditions, small roots may be injured in as little as 30 minutes. • Do not allow chemicals, trash, or other foreign debris to become mixed with the backfill. • If earthwork specifications allow it, firm the backfill to the same compaction a s the surrounding soil and no more. • Water the backfill to prevent excessive root drying. Grade or Ground Level Changes Grade changes should be avoided in order to prevent serious damage or death to a tree. Fill that is added over existing soils can smother and kill roots, or invite disease if piled around the trunk. Even temporary fills such as stockpiling mulch or soil in the CRZ of a tree for as little as several days during the construction process can have severe, long-term negative effects, though symptoms may not appear for several years. The extent of injury from adding soil around a tree varies with the kind, age, and condition of the tree; the depth and type of fill; drainage; and several other factors. Maple, oak, and evergreens are most susceptible, while elm, ash, willow, sycamore, and locust are least affected. Little can be done to save trees that have been suffering from soil added over an extended period of time. It is prudent to consider possible damage that may occur to a tree and take a lternative action before the fill is made; prevention is less expensive and more effective than attempting to correct the situation after damage has been done. Best practices for fill operations include the following: • Never place any fill or organic materials directly against the tree. • Never compact the soil within the CRZ. • If using no more than two to four inches of fill around existing trees, significant damage may be avoided if the fill has a coarser texture than the existing soil. Less damage to a tree’s roots is likely with a lowered grade than when it is raised, unless exposing or removing a great deal of the root mass. A general rule-of-thumb used by landscape architects is to remove no more than six inches of soil from the existing grade in the CRZ; however, this is dependent on the soils in which the tree is growing. A tree’s roots may all exist in the top foot of a shallow soil; removing the top six inches would have tremendous negative impact in that case.

Root pruning is best left to an ISA Certified Arborist, who can take into account the variables necessary to reduce the stress of the pruning to the tree.” DocuSign Envelope ID: A5115E6D-5FF1-4242-8D6A-1BDF53158A96 Page 13 of 16 Arborist Report - Encompass ES - 1711 Index Avenue NE TREE FROG LLC https://www.treefrogllc.com/ PO Box 307, Duvall, WA 98019 [P] 206-310-8254 [E] andycrossett@hotmail.com 9.
