Consulting Arborists LLC October 31, 2025 Page 3 of 39 ASSIGNMENT Provide a Tree Inventory/Protection Plan per RMC 4-8-120 D(20) for Short Plat of Parcel 3123059119. LIMITATIONS OF ASSIGNMENT The site plan is an early conceptual plan. This report is a preliminary report that may change as the project moves forward. This report is a limited to a Visual Assessment (VA) of the site and the trees. It is not a comprehensive risk assessment, structural assessment, or health assessment. METHODOLOGY To evaluate the trees, as well as to prepare this report, I drew upon my 30+ years of experience in the field of arboriculture and my formal education. I followed the protocol of the International Society of Arboriculture (ISA) and I performed my assessment using and/or considering the following Best Management Practices: ANSI A300 Part 2 – Soil Management a.) Modification b.) Fertilization & c.) Drainage. ANSI A300 Part 5 – Managing Trees During Site Planning, Site Development, and Construction. ANSI A300 Part 8 – Root Management. ANSI A300 Part 9 – Tree Risk Assessment (Second Edition). ISA BMP’s – Tree Inventories (Second Edition 2013) Best Management Practices were developed to aid in the interpretation of professional standards and guide work practices based upon current science and technology. This is a scientifically based process to look at the entire site, surrounding land and soil, as well as a general look at the trees themselves. SITE Parcel 3123059119 Gross 93,801sq. ft./ 2.15-acre NET 1 78,176 sq. ft./ 1.79-acre Proposed for a 4-lot short plat. A portion of the site was Zoned R4 and a portion R1.

Consulting Arborists LLC October 31, 2025 Page 6 of 39 TREE PROTECTION ZONES (TPZ) 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 are limited. General The TPZ is the optimal protection zone set to preserve trees during construction. The TPZ radius generally is 8-Inches to 18-Inches of protection for every 1-Inch of DBH, based on the trees size, vigor and construction tolerances (ANSI A300 Part 5 BMP, Matheny, Clark, 1998). The TPZ can usually safely be reduced by 20% as long as it does not impact the CRZ. Greater than 20% reductions may be possible, pending review, written permission, and direct over site of the work, by the Consulting Arborist. The trees to be saved, must be protected during construction by temporary 6’ tall chain-link, or like fencing, located 10’ beyond the edge of the trees farthest extending limbs on all sides (dripline). The individual tree protection zones (TPZ) are 10’ past the driplines of the tree(s), unless otherwise delineated by A.B.C. Consulting Arborist LLC. See Attachment 2 for tree specific TPZ and CRZ. No irrigation lines, trenches, or other utilities shall be installed within the TPZ, without detailed written instructions and the oversite of the Consulting Arborist, to reduce the impacts to the tree roots, and construction related stressors. Cuts or fills should impact no more than 20% of a tree’s root system. If topsoil is added to the root zone of a protected tree, the depth should not exceed 2 inches of a sandy loam or loamy fine sand topsoil and should not cover more than 20% of the root system. If roots are encountered outside the TPZ during construction, they shall be cut cleanly with a saw (not ripped or torn) and covered immediately with moist soil. Noxious vegetation within the critical root zone should be removed by hand. If a proposed save tree must be impacting by grading or fills, then the tree should be re-evaluated by A.B.C. Consulting Arborist LLC to determine if the tree can be saved with mitigating measures, or if the tree should be removed. See Attachment 3 for complete tree protection instructions. CRITICAL ROOT ZONES (CRZ) The CRZ is the area where the roots vital for the tree’s survival are located, the CRZ is generally ½ of the TPZ. At no time or for any reason shall the roots within the CRZ be impacted. See Attachment 2 for tree specific TPZ and CRZ. FENCING 6’ tall chain link (or like fencing) shall be installed the TPZs prior to commencement of site clearing and shall remain in place for the duration of the project. When possible, it is preferred that trees be fenced as a group, rather than individuals. At no time shall any vehicle or equipment be allowed inside the TPZ/Fencing. No placing or stockpiling of any material of any kind shall be allowed inside the TPZ. Talbot Hills – Short Plat - Tree Protection Plan, Renton, WA By, A.B.C. Consulting Arborists LLC October 31, 2025 Page 7 of 39 Removal of any vegetation within the TPZ shall be done by hand. Should any disturbance be required inside the TPZ to install utilities or any other needs during the construction period, they will require project specific instructions by the Consulting Arborist and approval by the city prior to undertaking any said activity in the TPZ. ROOT PROTECTION Any roots encountered of 1” in diameter or greater, shall be cut with loppers, pruners, reciprocal saw or like device to provide a clean smooth cut. At no time, shall 1” or greater diameter roots be ripped or torn. Exposed roots shall be covered with wet burlap, or like item, to keep roots from drying out and shall be covered with soil as soon as reasonably possible. Protect tree root systems from damage due to noxious materials caused by runoff or spillage while mixing, placing, or storing construction materials. Protect root systems from flooding, eroding, or excessive wetting caused by dewatering operations. Protect root systems from damage due to removal of adjacent trees.

Tree Protection Fencing: a. Tree Protection Fences will need to be placed around each tree or group of trees to be retained. i. Tree Protection Fences are to be placed according to the attached drawing (bottom of attachment) at a distance of not less than 10’ feet outside the dripline of the tree or group of trees to be saved, or at the designated TPZ See Attachment 2 for TPZ/CRZ ii. Tree Protection Fences must be inspected prior to the beginning of any demolition or construction work activities. iii. Nothing must be parked or stored within the Tree Protection Fences—no equipment, vehicles, soil, debris, or construction supplies of any sorts. b. Signs: i. The Tree Protection Fences need to be clearly marked with the following or similar text in four inch or larger letters every 20’ TREE PROTECTION FENCE DO NOT ENTER! DO NOT PARK OR STORE MATERIALS WITHIN THE PROTECTION AREA Questions contact Daniel Maple of A.B.C. Consulting Arborists LLC. Cell: (509) 953-0293 Email: Daniel@AbcArborist.Com Other (425)999-0867 Signs along the TPZ may be waived at the discretion of the City and/or its officials. 2. Cement Trucks/Washout: a. Cement trucks must not be allowed to deposit waste or wash out materials from their trucks within the Tree Protection Fences. b. No waste, wash out, or contaminated water shall be allowed to flow into the Tree Protection Area. 3. Canopy Pruning: a. The canopies of some of the trees may need to be properly pruned to allow Sight lines (vehicular), access of equipment, materials, or building and construction clearance. b. If so, the pruning must be done by an International Society of Arboriculture, (ISA) Certified Arborist using current industry standard pruning techniques. (ANSI A300 Pruning Standards and ANSI Z131.1 Safety Standards as well as all OSHA, WISHA, and local standards must be followed.) c. Plant debris can be chipped and utilized on site for the mulch under the trees. Talbot Hills – Short Plat - Tree Protection Plan, Renton, WA By, A.B.C. Consulting Arborists LLC October 31, 2025 Page 31 of 39 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 an Airspade™, shovel, hand pruners, a pair of loppers, a handsaw, and a power saw (a “saws all” type reciprocating saw 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. c. 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 Airspade™ (recommended) or 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: 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 three to six inches of mulch. The mulch will minimize evaporation and will also stimulate the microbial activity of the soil which is another benefit to the health of the tree. a. 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. b. 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. Talbot Hills – Short Plat - Tree Protection Plan, Renton, WA By, A.B.C.

Install as shown on plans 5’ min past Dripline, or per specific TPZ/CRZ instructions. Signs installed every 20-25-feet TREE PROTECTION FENCE DO NOT ENTER! DO NOT PARK OR STORE MATERIALS WITHIN THE PROTECTION AREA Include Arborist Contact Info. Six-foot high temporary chain link (or like material) fencing shall be installed as shown on plans. Fencing shall be installed prior to construction activity and remain in place until construction is completed. Fencing panels are recommended. Fencing shall completely encircle the tree(s). Install fence posts using pier blocks. Avoid driving posts or stakes into major roots. Make a clean straight cut, using loppers, reciprocal saw, or like tool, to remove damaged portion of root(s) over 1” inch diameter that are damaged during construction. ALL exposed roots shall be temporarily covered with damp burlap and covered with soil the same day, if possible, to prevent drying out. If not possible, the burlap must be kept moist at all times. Work within the protection fencing shall be done manually. No stockpiling of materials, soil, debris, vehicular traffic, or storage of machinery or equipment shall be allowed within the limits of the fencing. Cement trucks must not be allowed to deposit waste or wash out materials from their trucks within the tree protection fences, or in a manner that would allow the waste or wash out material to enter the TPZ. The area within the tree protection fencing she’d be covered with wood chips, hog fuel, or similar materials, to a depth of 3 to 6 inches. The materials should be placed prior to beginning construction and remain until the tree protection fencing was taken down. Should the tree protection fencing need to be installed inside the TPZ to allow for construction activity, then the following shall be done. For construction equipment, cover the area from the tree protection fencing to the outer edge of the TPZ with 8 to 10 inches of wood chips, hog fuel, or similar materials, to reduce compaction cover area with steel plates. For foot traffic’ cover the area from the tree protection fencing to the outer edge of the TPZ with 6 inches of wood chips, hog fuel, or similar materials, to reduce compaction, cover with ¾ inch to 1-inch plywood. The steel plates, plywood and wood chips are to remain in place until all construction activity is completed. The steel plates, plywood and woodchips shall then be removed and the tree protection fencing installed along the outer edge of the tree protection zone.

There are special circumstances related to the size, shape, topography, location, or surroundings of the subject property; or b. The strict application of the code would prevent reasonable use of property; or c. The strict application of the code would prevent compliance with minimum density requirements of the zone; or d. The project is a short plat with four (4) or fewer lots. Please attach a written justification demonstrating compliance with the requirements and criteria as descripted above. TREE REPLACEMENT QUANTITY Tree replacement quantity is determined based on the credit value of the trees proposed for removal. Larger, higher priority trees shall be used for calculation of tree replacement. Identify the quantity of each tree requested to be removed in lieu of 30% retention, based on tree size. List the identification number of each tree, as indicated in the arborist report.
