The subject site is proposed for redevelopment. Based on the Site Plan C1.00 (KPFF, 3/17/2023) and correspondence with the project team, 145 trees will require removal. The project proposes retaining and protecting 80 trees on the property for a total retention of 147.5 tree units. Assignment and Scope of Work This report outlines the site inspections by Andrea Starbird and Tyler Bunton, of Tree Solutions Inc., on January 4 and 5, 2022 and February 24, 2022. We were asked to visit the site and assess trees 6-inches DSH and greater on-site. We were asked to produce an Arborist Report documenting our findings and management recommendations. Lis Soldano, Vice President of Development for Intracorp Homes, requested these services to inform development planning. Draft Arborist Report Intracorp: 32818 1st Ave S Federal Way March 17, 2023 Tree Solutions Inc., Consulting Arborists Page 2 Observations Site The 255,610 square-foot (5.9 acre) site is located at the corner of S 328th St and 1st Ave S in Federal Way, Washington. The site area minus the area proposed for roads is equal to 206,175 square feet (4.7 acres). A warehouse building currently exists on-site, as well as sidewalks, a large parking lot and remnants of a demolished structure within a pool. The parcel number is 1721049038 and is zoned Office Park (OP). The site abuts parcels zoned multi- family 1800 and multi-family 2400. According to the City of Federal Way Critical Areas Map dated May 2016, there are no environmentally sensitive areas on-site. Proposed Plans The reviewed plans (Site Plan C1.00 KPFF, 3/17/2023) propose demolition of existing site structures and hardscape to construct a townhome housing development. Trees The site has some ornamental landscaping throughout, and is bordered by a native remnant forest on the south and east sides. Tree species on-site are primarily native with some ornamental species growing near existing buildings. A majority of the trees on-site were Douglas-fir (Pseudotsuga menziesii), Pacific madrone (Arbutus menziesii), and Scots pine (Pinus sylvestris), and were primarily in good to fair condition. On the east side of the property, part of the forested area is fenced off from the developed portion of the site and provides screening between the subject site and the adjacent neighborhood. The trees are growing as a grove and exhibit forest-like growth, with the edge trees having a fuller canopy than interior trees. We have attached an annotated Site Plan (C1.00 KPFF, 3/17/2023) to serve as the tree site map, and a table of trees that has detailed information about each tree’s species, condition, diameter and dripline measurements. Discussion—Construction Impacts There are a total of 429.5 tree units on the parcel. The site is proposed to be rezoned to RM 1800. Federal Way Municipal Code (FWMC) 19.120.130(2) requires that parcels zoned RM 1800 have a minimum tree density of 30 tree units per acre. For this site a total of 141 tree units are required. Based on the reviewed Site Plan (C1.00 KPFF, 3/17/2023), the project proposes retaining 80 trees for 147.5 tree units. Enough tree units are proposed to be retained to meet the minimum tree density for this site. Therefore, no replacement trees will be required to be planted to reach the minimum tree density. FWMC 19.130.160(2) requires a no disturbance area around retained trees of 12-inches of radius for each inch of trunk diameter, or any other no disturbance area proposed by the applicant shall be determined by a qualified arborist and subject to review and approval by the director. Outlined below Draft Arborist Report Intracorp: 32818 1st Ave S Federal Way March 17, 2023 Tree Solutions Inc., Consulting Arborists Page 3 are the no disturbance areas recommended for this site. These are based on ISA best management practices and our experience with trees and construction in our area. · No work should occur within an area of eight times (8x) trunk diameter or within six-feet of tree trunks, whichever is greater, unless the work is reviewed, approved, and monitored by the project arborist to determine specific impacts to trees. · No work should occur within an area of five times (5x) trunk diameter or within 6 feet of tree trunks, whichever is greater, to maintain tree stability. If work is proposed within this area, it should be monitored by the project arborist and tree retention determined when impacts are assessed in the field. Tree 276, proposed for retention, has existing hardscape located within the tree protection fencing. The tree protection fencing should be in place as shown on the attached annotated Site Plan (C1.00 KPFF, 3/17/2023) and only moved when demolition of the existing hardscape occurs. Immediately after demolition is complete the fencing should be replaced in its original location. Tree 480 is an off-site tree proposed for retention which has a detention vault proposed within 8x trunk diameter. The initial excavation for the detention vault in this location should be monitored by the project arborist to determine impacts to the tree. The reviewed Site Plan (C1.00 KPFF, 3/17/2023) does not have proposed grading. All grading should remain outside of 8x trunk diameter, or be limited to 1 foot of well-draining fill to allow for the percolation of water to existing roots. Grade cuts within 8x trunk diameter should be assessed to determine impacts to adjacent trees. Some trees may require pruning for building and utility installation clearance. All clearance pruning of retained trees should be performed by an ISA certified arborist following current ANSI A300 pruning standards. I recommend Tree Solutions attends any pre-construction meetings to ensure tree protection measures are in place prior to demolition or grading work. The project is required to provide a bond, letter of credit or other means of assurance acceptable to the director to ensure the installation, maintenance, and adequate performance of tree protection measures (FWMC 19.120.240(2)(a)). This bond will cover a period of two years and requires tree replacement and potential fines should any tree planned for retention be removed, be irreparably damaged, or die. One hundred and forty-five trees are proposed for removal due to their proximity to proposed development. Trees proposed for removal within tree protection areas should be cut as close to the ground as possible with the stumps left in place, be ground out, or have hydro excavation performed around the stumps to sever the roots as close as possible to the stump to minimize disturbance to soils within the tree protection areas. Recommendations Draft Arborist Report Intracorp: 32818 1st Ave S Federal Way March 17, 2023 Tree Solutions Inc., Consulting Arborists Page 4 · Protect all retained trees as outlined in this report and on the attached Arborist Annotated Site Plan C1.00 (KPFF, 3/17/2023). · Have the project arborist on-site for the excavation adjacent to tree 480 to assess impacts. · Use well-draining fill around trees if grade is to be raised between 5x and 8x trunk diameter. · Include Tree Solutions Inc. in pre-construction meetings to ensure tree protection is in place and adequate to prevent any unintentional damage to retained on- and off-site trees during site work. · All clearance pruning of retained trees should be performed by an ISA certified arborist following current ANSI A300 pruning standards.

Draft Arborist Report Intracorp: 32818 1st Ave S Federal Way March 17, 2023 Tree Solutions Inc., Consulting Arborists Page 10 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 outlined in 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. We used alphabetical identifiers for trees off-site. 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. Draft Arborist Report Intracorp: 32818 1st Ave S Federal Way March 17, 2023 Tree Solutions Inc., Consulting Arborists Page 11 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. Draft Arborist Report Intracorp: 32818 1st Ave S Federal Way March 17, 2023 Tree Solutions Inc., Consulting Arborists Page 12 Tree Protection Specifications The following is a list of protection measures that should be employed before, during and after construction to ensure the long-term viability of retained trees. These specifications can be copied onto plans and/or into contract documents. 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 Federal Way requires a tree protection zone (TPZ) of 12- inches for each inch of trunk diameter. This may be reduced based on the project arborist recommendation and approval by the director. For purposes of these specifications the TPZ is 8 times trunk diameter. 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 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: In areas where work such as installation of utilities is required within the TPZ, a locking gate will be installed in the fencing to facilitate access. 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 4- to 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. Draft Arborist Report Intracorp: 32818 1st Ave S Federal Way March 17, 2023 Tree Solutions Inc., Consulting Arborists Page 13 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 5-feet outside the dripline of retained trees. No exhaust shall come in contact with foliage for prolonged periods of time. 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 native 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: Limit fill to 1-foot of uncompacted well-draining soil, within the TPZ of retained trees. In areas where additional fill is required, consult with the project arborist. Fill must be kept at least 1-foot from the trunks of trees. 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. The roots can also 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 must be performed by an ISA certified arborist in accordance with American National Standards Institute ANSI-A300 2017 Standard Practices for Pruning. 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 on-site 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 Preliminary Table of Trees 32818 1st Ave S, Federal Way WA 98003 Arborist: TB, AS Date of Inventory: 1/3, 4/2022, 2/24/2022 Table Prepared: 3/17/2023 Tree ID Scientific Name Common Name DSH (inches) DSH Multistem Health Condition Structural Condition Dripline Radius (feet)Proposed Action Tree Units Notes 252 Acer platanoides Norway maple 14.9 Good Fair 23.6 Remove 0.0 growing at edge of crib, phototropic to southeast 253 Pinus sylvestris Scots Pine 21.2 Good Good 28.9 Remove 0.0 ivy at base, kinked at 15’ 254 Pseudotsuga menziesii Douglas-fir 18.8 Good Good 17.8 Remove 0.0 interior dieback due to shading 255 Pseudotsuga menziesii Douglas-fir 15.0 Good Good 15.6 Remove 0.0 256 Pseudotsuga menziesii Douglas-fir 20.6 Good Good 17.4 Remove 0.0 257 Pseudotsuga menziesii Douglas-fir 22.6 Good Good 18.9 Remove 0.0 258 Pseudotsuga menziesii Douglas-fir 17.3 Good Good 18.7 Remove 0.0 259 Acer platanoides Norway maple 9.3 Good Good 12.9 Retain 1.5 measured narrowest point below union 260 Pseudotsuga menziesii Douglas-fir 18.5 Good Good 19.3 Remove 0.0 261 Pseudotsuga menziesii Douglas-fir 14.4 Good Good 10.6 Remove 0.0 corrected lean north 262 Pseudotsuga menziesii Douglas-fir 11.4 Good Good 15.0 Remove 0.0 263 Pseudotsuga menziesii Douglas-fir 12.0 Good Good 14.5 Remove 0.0 264 Pseudotsuga menziesii Douglas-fir 12.4 Good Good 16.5 Remove 0.0 265 Pseudotsuga menziesii Douglas-fir 14.0 Good Good 16.6 Remove 0.0 266 Pseudotsuga menziesii Douglas-fir 17.8 Good Good 15.7 Remove 0.0 corrected lean. row of firs shares canopy 267 Pinus sylvestris Scots Pine 16.2 Good Good 27.7 Remove 0.0 fair bit of sapsucker activity 268 Acer platanoides Norway maple 10.6 Good Good 15.4 Remove 0.0 269 Pinus nigra Austrian Black Pine 11.6 Good Good 11.5 Remove 0.0 270 Acer platanoides Norway maple 7.0 Fair Fair 13.3 Remove 0.0 in decline, sapsucker activity, bark slugging, phototropic to east 271 Pinus sylvestris Scots Pine 19.5 Good Good 24.8 Remove 0.0 272 Pinus sylvestris Scots Pine 13.4 Good Good 19.1 Remove 0.0 273 Pinus sylvestris Scots Pine 14.3 Good Good 20.6 Retain 2.0 274 Pinus sylvestris Scots Pine 13.8 Good Good 17.1 Retain 2.0 codominant at 8 feet with seam to 15 feet, phototropic to east 275 Pinus nigra Austrian Black Pine 14.1 Good Good 22.6 Retain 2.0 confirmation still needed 276 Acer platanoides Norway maple 8.4 Good Good 10.9 Retain 1.5 significant surface roots present to east, shared root zone with non- significant Douglas-fir to north 277 Pseudotsuga menziesii Douglas-fir 5.8 Good Good 7.7 Retain 1.0 278 Pseudotsuga menziesii Douglas-fir 11.5 Good Fair 12.0 Remove 0.0 corrected lean; surface roots with old wounds 279 Pseudotsuga menziesii Douglas-fir 14.2 Good Good 15.6 Remove 0.0 280 Pseudotsuga menziesii Douglas-fir 8.8 Fair Fair 7.9 Remove 0.0 stunted growth 281 Pseudotsuga menziesii Douglas-fir 11.7 Good Good 13.0 Remove 0.0 282 Pseudotsuga menziesii Douglas-fir 13.7 Good Good 13.1 Retain 2.0 283 Pseudotsuga menziesii Douglas-fir 15.6 Good Good 15.2 Remove 0.0 284 Acer platanoides Norway maple 7.1 Good Good 10.3 Remove 0.0 285 Pseudotsuga menziesii Douglas-fir 12.1 Good Good 12.5 Remove 0.0 286 Pseudotsuga menziesii Douglas-fir 12.0 Good Good 14.0 Retain 2.0 surface roots 287 Acer platanoides Norway maple 8.0 Good Good 14.3 Retain 1.5 288 Pseudotsuga menziesii Douglas-fir 19.7 15.5,12.2 Good Good 16.8 Retain 2.5 codominant at base 289 Pseudotsuga menziesii Douglas-fir 14.6 Good Good 13.1 Remove 0.0 290 Pseudotsuga menziesii Douglas-fir 16.3 Good Good 17.7 Remove 0.0 291 Acer platanoides Norway maple 9.7 Fair Good 10.4 Retain 1.5 stunted growth 292 Pseudotsuga menziesii Douglas-fir 16.3 Good Good 15.2 Remove 0.0 293 Prunus spp. (serrula, serrulata) Flowering Cherry 14.4 Fair Fair 10.6 Remove 0.0 measured at base, multistemmed but grafted 294 Prunus spp. (serrula, serrulata) Flowering Cherry 6.9 Fair Fair 8.8 Remove 0.0 measured narrowest point below union, junipers at base 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.
