We assessed tree impacts based on two scenarios, one with open trench installation and one with trenchless installation of utility lines between the grinder pumps and the low-pressure sanitary sewer force main. Open trench installation would require the removal of 21 trees and trenchless installation would require the removal of four trees. Thirteen trees would have construction occur within tree driplines but could be retained following specific construction methods outlined in this report. Replacement of removed trees must follow City of Renton and King County Parks requirements. Assignment and Scope of Work This report outlines the site inspection by Tyler Bunton and Julian Garcia, of Tree Solutions Inc., on February 26th and 27th 2025. We were asked to visit the site and assess all significant trees within, and adjacent to, the project area. We were asked to produce an Arborist Report documenting our findings Arborist Report Carollo Engineers Inc.: Kenneydale Lakeline Sewer, Renton, WA April 15, 2025 Tree Solutions Inc., Consulting Arborists Page 2 and management recommendations. Cheyenne Thompson of Carollo Engineers Inc., requested these services to aid in project planning. Observations and Discussion Site The site consists of 59 privately owned parcels, City of Renton right-of-way (ROW), and King County Parks owned parcels in the Kennydale neighborhood of Renton along the Lake Washington shoreline. There are single-family houses with associated structures and landscaping on the private parcels. The ROW and King County properties have access roads to the private parcels, landscaping, and the King County Eastrail trail. Trees All of the inventoried trees appeared to have been planted as part of landscaping for the single-family homes or the adjacent Eastrail trail with the exception of some of the black cottonwood (Populus trichocarpa) and bigleaf maple (Acer macrophyllum) trees. The trees along the Eastrail trail and in the ROW generally appeared to be in worse health than the trees on private property, likely due to a lack of irrigation. We have attached an annotated survey of the site to serve as the Tree Site Map and a Table of Trees that has detailed information about each tree. City of Renton Code Private Property The City of Renton requires a minimum of 30 tree credits per acre on private parcels (Renton Municipal Code (RMC) 4-4-130.H.1.b. Additionally, 30 percent of existing significant trees are required to be retained on properties subject to an active land development permit. A tree retention and credit worksheet will be required for properties which will have significant trees removed. Right-of-Way Removed trees within City of Renton ROW must be replaced according to RMC 9-13-8.B with a replacement ratio of one planted tree for each removed tree. King County Code King County will likley require replacement of removed trees on King County property. The numbers of replacement trees to be planted will likley follow King County Code 16.82.156.E.2.a & b. Replacement requirements for removed trees should be confirmed with King County. Discussion—Construction Impacts Tree Protection Requirements RMC 4-4-130.H.10 requires 6-foot-tall chain-link tree protection fencing be installed at the dripline of retained trees and that the fencing be anchored in place with posts anchored into the ground to a depth that will ensure fencing remains upright throughout the project. Additional minimum protection measures can be found in RMC 4-4-130.H.10. In addition to the City of Renton requirements we also recommend following the Tree Protection Specifications outlined in Appendix F. Arborist Report Carollo Engineers Inc.: Kenneydale Lakeline Sewer, Renton, WA April 15, 2025 Tree Solutions Inc., Consulting Arborists Page 3 Tree Impacts – Trenchless Construction Option If trenchless construction methods are implemented to install the utility lines between the grinder pumps and the low-pressure sanitary sewer force main, removal of four trees (272, 273, 275, 308) will be required due to impacts from the installation of the grinder pumps. Thirteen trees (29, 30, 59, 66, 71, 83, 190-194, 237, 276) will have impacts within their driplines from installation of the grinder pumps and/or installation of new sanitary sewer lines from houses to the grinder pumps. We recommend that hydrovac excavation occur around the edges of the excavation for installation of the grinder pumps to allow any roots growing in these areas to be cleanly cut at the edges of excavation. Five trees (190-194) are not currently located on the plans but are located near a proposed grinder pump and utility lines. These trees should be surveyed to determine their precise locations in relation to proposed work. Some of these trees may require removal depending on their proximity to excavation. Tree Retention and Replacement If trenchless construction is performed trees will be required to be removed from three parcels. Two parcels (3342700100, 3342700176) would have one of two existing trees removed resulting in 50 percent retention. The remaining tree on each parcel meets the required credit amount for the size of the property and therefore no tree replacement would be required. Parcel 3342700126 would have both trees removed due to the size of the parcel and the required location of the grinder pumps for this and the adjacent parcel. In this situation the largest tree is used to determine the number of replacement credits required. Tree 272 is the largest of the two trees at 14 inches diameter at standard height which results in a total of 6 replacement tree credits required for its removal. Due to the size and shape of the property and the location of existing structures and proposed grinder pumps on parcel 3342700126 there is no place to plant replacement trees on-site. Alternative nearby planting locations should be determined in conjunction with the City of Renton. Tree Impacts – Open Trench Construction Option If an open trench is used to install the utility lines between the grinder pumps and the low-pressure sanitary sewer force main, removal of 21 trees (64, 70, 72, 75-78, 138, 164, 190-193, 196, 197, 235, 237, 272, 273, 275, 308) will be required due to impacts from the installation of the grinder pumps and open trenching. Thirteen trees (29, 30, 59, 66, 71, 83, 92, 131, 132, 133, 163, 194, 276) will have impacts within their driplines from utility installation. We recommend that hydrovac excavation occur around the edges of the excavation for installation of the grinder pumps to allow any roots growing in these areas to be cleanly cut at the edges of excavation. We also recommend monitoring any excavation adjacent to the trees for utility line installation to determine impacts to the trees. Tree Retention and Replacement Since open trench construction to install the utility lines between the grinder pumps and the low- pressure sanitary sewer force main is not the preferred method, I have not calculated the per parcel retention percentages and replacement requirements. This can be provided upon request. Arborist Report Carollo Engineers Inc.: Kenneydale Lakeline Sewer, Renton, WA April 15, 2025 Tree Solutions Inc., Consulting Arborists Page 4 Recommendations • Provide replacements for removed trees according to City of Renton and King County Parks requirements. • Survey the locations of trees 190 through 194. • Follow Tree Protection Specifications outlined in Appendix F and the minimum tree protection requirements outlined in RMC 4-4-130.H.10.

An independent inventory and evaluation of the site’s soil should be obtained by a qualified professional if an additional understanding of the site’s characteristics is needed to make an informed decision. 9 Our assessments are made in conformity with acceptable evaluation/diagnostic reporting techniques and procedures, as recommended by the International Society of Arboriculture. Arborist Report Carollo Engineers Inc.: Kenneydale Lakeline Sewer, Renton, WA April 15, 2025 Tree Solutions Inc., Consulting Arborists Page 9 Methods Measuring We measured the diameter of each tree at 54 inches above grade, diameter at standard height (DSH). If a tree had multiple stems, we measured each stem individually at standard height and determined a single-stem equivalent diameter by using the method the Guide for Plant Appraisal, 10th Edition Second Printing published by the Council of Tree and Landscape Appraisers. A tree is regulated based on this single-stem equivalent diameter value. Tagging We tagged each tree with a circular aluminum tag at eye level. We assigned each tree a numerical identifier on our map and in our tree table, corresponding to this tree tag. Evaluating We evaluated tree health and structure utilizing visual tree assessment (VTA) methods. The basis behind VTA is the identification of symptoms, which the tree produces in reaction to a weak spot or area of mechanical stress. A tree reacts to mechanical and physiological stresses by growing more vigorously to re-enforce weak areas, while depriving less stressed parts. An understanding of the uniform stress allows the arborist to make informed judgments about the condition of a tree. Rating When rating tree health, we took into consideration crown indicators such as foliar density, size, color, stem and shoot extensions. When rating tree structure, we evaluated the tree for form and structural defects, including past damage and decay. Tree Solutions has adapted our ratings based on the Purdue University Extension formula values for health condition (Purdue University Extension bulletin FNR-473- W - Tree Appraisal). These values are a general representation used to assist arborists in assigning ratings. Health Excellent - Perfect specimen with excellent form and vigor, well-balanced crown. Normal to exceeding shoot length on new growth. Leaf size and color normal. Trunk is sound and solid. Root zone undisturbed. No apparent pest problems. Long safe useful life expectancy for the species. Good - Imperfect canopy density in few parts of the tree, up to 10% of the canopy. Normal to less than ¾ typical growth rate of shoots and minor deficiency in typical leaf development. Few pest issues or damage, and if they exist they are controllable or tree is reacting appropriately. Normal branch and stem development with healthy growth. Safe useful life expectancy typical for the species. Fair - Crown decline and dieback up to 30% of the canopy. Leaf color is somewhat chlorotic/necrotic with smaller leaves and “off” coloration. Shoot extensions indicate some stunting and stressed growing conditions. Stress cone crop clearly visible. Obvious signs of pest problems contributing to lesser condition, control might be possible. Some decay areas found in main stem and branches. Below average safe useful life expectancy Poor - Lacking full crown, more than 50% decline and dieback, especially affecting larger branches. Stunting of shoots is obvious with little evidence of growth on smaller stems. Leaf size and color reveals overall stress in the plant. Insect or disease infestation may be severe and uncontrollable. Extensive decay or hollows in branches and trunk. Short safe useful life expectancy. Arborist Report Carollo Engineers Inc.: Kenneydale Lakeline Sewer, Renton, WA April 15, 2025 Tree Solutions Inc., Consulting Arborists Page 10 Structure Excellent - Root plate undisturbed and clear of any obstructions. Trunk flare has normal development. No visible trunk defects or cavities. Branch spacing/structure and attachments are free of any defects. Good - Root plate appears normal, with only minor damage. Possible signs of root dysfunction around trunk flare. Minor trunk defects from previous injury, with good closure and less than 25% of bark section missing. Good branch habit; minor dieback with some signs of previous pruning. Codominant stem formation may be present, requiring minor corrections. Fair - Root plate reveals previous damage or disturbance. Dysfunctional roots may be visible around the main stem. Evidence of trunk damage or cavities, with decay or defects present and less than 30% of bark sections missing on trunk. Co-dominant stems are present. Branching habit and attachments indicate poor pruning or damage, which requires moderate corrections. Poor - Root plate disturbance and defects indicate major damage, with girdling roots around the trunk flare. Trunk reveals more than 50% of bark section missing. Branch structure has poor attachments, with several structurally important branches dead or broken. Canopy reveals signs of damage or previous topping or lion-tailing, with major corrective action required. Arborist Report Carollo Engineers Inc.: Kenneydale Lakeline Sewer, Renton, WA April 15, 2025 Tree Solutions Inc., Consulting Arborists Page 11 Tree Protection Specifications The following is a list of protection measures that must be employed before, during and after construction to ensure the long-term viability of retained trees. 1. Project Arborist: The project arborists shall at minimum have an International Society of Arboriculture (ISA) Certification and ISA Tree Risk Assessment Qualification. 2. Tree Protection Zone (TPZ): The city of Renton requires a tree protection zone (TPZ) which equals the dripline of the tree. In some cases, the TPZ may extend outside tree protection fencing. Work within the TPZ must be approved and monitored by the project arborist. 3. Tree Protection Fencing: Tree protection shall consist of 6-foot-tall chain-link fencing installed at the TPZ as approved by the project arborist. Fence posts shall be anchored into the ground or bolted to existing hardscape surfaces. a. Where trees are being retained as a group the fencing shall encompass the entire area including all landscape beds or lawn areas associated with the grove. b. Per arborist approval, TPZ fencing may be placed at the edge of existing hardscape within the TPZ to allow for staging and traffic. c. Where work is planned within the TPZ, install fencing at edge of TPZ and move to limits of disturbance at the time that the work within the TPZ is planned to occur. This ensures that work within the TPZ is completed to specification. d. Where trees are protected at the edge of the project boundary, construction limits fencing shall be incorporated as the boundary of tree protection fencing. 4. Access Beyond Tree Protection Fencing: The project manager or project arborist shall be present when tree protection areas are accessed. 5. Tree Protection Signage: Tree protection signage shall be affixed to fencing every 20 feet. Signage shall be fluorescent, at least 2’ x 2’ in size. Signage will note: “Tree Protection Area – Do Not Enter: Entry into the tree protection area is prohibited unless authorized by the project manager.” Signage shall include the contact information for the project manager and instructions for gaining access to the area. 6. Filter / Silt Fencing: Filter / silt fencing within the TPZ of retained trees shall be installed in a manner that does not sever roots. Install so that filter / silt fencing sits on the ground and is weighed in place by sandbags or gravel. Do not trench to insert filter / silt fencing into the ground. 7. Monitoring: The project arborist shall monitor all ground disturbance at the edge of or within the TPZ, including where the TPZ extends beyond the tree protection fencing. 8. Soil Protection: No parking, foot traffic, materials storage, or dumping (including excavated soils) are allowed within the TPZ. Heavy machinery shall remain outside of the TPZ. Access to the tree protection area will be granted under the supervision of the project arborist. If project arborist allows, heavy machinery can enter the area if soils are protected from the load. Acceptable methods of soil protection include applying 3/4-inch plywood over 6 inches of wood chip mulch or use of AlturnaMats® (or equivalent product approved by the project arborist). Retain existing paved surfaces within or at the edge of the TPZ for as long as possible. 9. Soil Remediation: Soil compacted within the TPZ of retained trees shall be remediated using pneumatic air excavation according to a specification produced by the project arborist. 10. Canopy Protection: Where fencing is installed at the limits of disturbance within the TPZ, canopy management (pruning or tying back) shall be conducted to ensure that vehicular traffic does not damage canopy parts. Exhaust from machinery shall be located five feet outside the dripline of retained trees. No exhaust shall come in contact with foliage for prolonged periods of time. Arborist Report Carollo Engineers Inc.: Kenneydale Lakeline Sewer, Renton, WA April 15, 2025 Tree Solutions Inc., Consulting Arborists Page 12 11. Duff/Mulch: Apply 6 inches of arborist wood chip mulch or hog fuel over bare soil within the TPZ to prevent compaction and evaporation. TPZ shall be free of invasive weeds to facilitate mulch application. Keep mulch 1 foot away from the base of trees and 6 inches from retained understory vegetation. Retain and protect as much of the existing duff and understory vegetation as possible. 12. Excavation: Excavation done at the edge of or within the TPZ shall use alternative methods such as pneumatic air excavation or hand digging. If heavy machinery is used, use flat front buckets with the project arborist spotting for roots. When roots are encountered, stop excavation and cleanly sever roots. The project arborist shall monitor all excavation done within the TPZ. 13. Fill: In areas where fill is required consult with the project arborist. 14. Root Pruning: Limit root pruning to the extent possible. All roots shall be pruned with a sharp saw making clean cuts. Do not fracture or break roots with excavation equipment. 15. Root Moisture: Root cuts and exposed roots shall be immediately covered with soil, mulch, or clear polyethylene sheeting and kept moist. Water to maintain moist condition until the area is back filled. Do not allow exposed roots to dry out before replacing permanent back fill. 16. Hardscape Removal: Retain hardscape surfaces for as long as practical. Remove hardscape in a manner that does not require machinery to traverse newly exposed soil within the TPZ. Where equipment must traverse the newly exposed soil, apply soil protection as described in section 8. Replace fencing at edge of TPZ if soil exposed by hardscape removal will remain for any period of time. 17. Tree Removal: All trees to be removed that are located within the TPZ of retained trees shall not be ripped, pulled, or pushed over. The tree should be cut to the base and the stump either left in place or ground out. A flat front bucket can also be used to sever roots around all sides of the stump, or the roots can be exposed using hydro or air excavation and then cut before removing the stump. 18. Irrigation: Retained trees with soil disturbance within the TPZ will require supplemental water from June through September. Acceptable methods of irrigation include drip, sprinkler, or watering truck. Trees shall be watered three times per month during this time. 19. Pruning: Pruning required for construction and safety clearance shall be done with a pruning specification provided by the project arborist in accordance with American National Standards Institute ANSI-A300 2017 Standard Practices for Pruning. Pruning shall be conducted or monitored by an arborist with an ISA Certification. 20. Plan Updates: All plan updates or field modification that result in impacts within the TPZ or change the retained status of trees shall be reviewed by the senior project manager and project arborist prior to conducting the work. 21. Materials: Contractor shall have the following materials onsite and available for use during work in the TPZ: • Sharp and clean bypass hand pruners • Sharp and clean bypass loppers • Sharp hand-held root saw • Reciprocating saw with new blades • Shovels • Trowels • Clear polyethylene sheeting • Burlap • Water Table of Trees Kennydale Sewer Project Arborist: TB, JG Date of Inventory: 2/26 and 2/27/2025 Table Prepared: 4/15/2025 DSH (Diameter at Standard Height) is measured 4.5 feet above grade, or as specified in the Guide for Plant Appraisal, 10th Edition , published by the Council of Tree and Landscape Appraisers.
