Tree Inventory assessments were made in accordance with American National Standards Institute (ANSI) A300 Part 5 standards. This report is more of an inventory styled report, this will help establish tree protections regarding tree removal, and retention determinations. Visual Tree Assessments is an outlined process in accordance with Tree Risk Assessment Qualification (TRAQ) program and is a recognized standard of care by the International Society of Arboriculture (ISA) to evaluate tree health and risk. I have included a detailed report of my findings below, along with an inventory styled matrix covering overall tree measurement and characteristics. Please feel free to contact me with any questions you may have. Yours, Cody Herron Page 2 of 53 Parcel 1196003780, Federal Way Cody Herron ABC Herron Tree LLC 425-293-2443 ISA Certified Arborist #PN-6967A Certified Tree Risk Assessor mountainredd@comcast.net Contents • Assignment • Personal qualifications, scope of work and methodology • Site Observations • Methods used to determine tree location and tree health • Site Map • Tree Assessment Matrix • GPS Coordinates • Discussion and conclusion • Tree Protection Plan • Tree Planting Plan • References • Waiver of Liability Assignment On September 20, 2023, I was asked to complete an arborist report for parcel 1196003800 which has not yet been assigned an address by the county. The report includes all trees 8” diameter at breast height (DBH) and above on this parcel. This report covers criteria set forth under the City of Federal Way’s tree regulations as of the date of this report. Personal qualifications, scope of work and methodology: The knowledge I used to evaluate the trees comes from over 20 years of experience in the tree care industry, including two years of schooling from South Seattle Community College. I am a recognized Journeyman Tree trimmer with 12 years of experience through the International Brotherhood Electrical Workers (IBEW). I also have over 10 years’ experience as an ISA certified arborist, including six years working for Snohomish County Public Utility District (PUD) as an arborist. I am currently employed by King County as a Vegetation Specialist Arborist for Road Services Division. I have also worked for Seattle City Light and Washington State Department of Transportation in performing tree maintenance and general vegetation management, mitigation, and noxious weed control. In addition to my experience and ISA certification maintained in good standing, I am also TRAQ certified (Tree Risk Assessment Qualified). I have relied on my training in these areas to perform the duties outlined. I followed the protocol delineated by the ISA for Level 2 Visual Assessment Process. By doing so I am examining each tree independently as well as collectively as groups or stands of trees provide stability and can lower risk of independent tree failure. This scientific process examines tree health (e.g., size, vigor, and insect and disease process) as well as site condition (soil, conditions, nursery stumps, anaerobic conditions, etc.).

Visual assessment includes looking for and determining the significance of the defects and structural conditions. Some structural defects or conditions are more likely to lead to failure than others. Individual defects or conditions may not by themselves indicate a serious structural problem, but in combination with other conditions they may contribute to failure. All tree species have widely varying lifespans and tolerance capabilities to wound healing from damage caused by biotic and abiotic forces. Knowledge of failure patterns (disease, lifespan, environmental conditions, and species characteristics) associated with different species is critical in making effective reports. Site Observations: The parcel at 1196003800, Federal Way is an undeveloped lot of 40,800 square feet per the King County Parcel Viewer website. I arrived on site at around 9:00 am on October 8, 2023. This lot is slightly sloping with a southern aspect. There are several small seeping areas that indicate wetlands on site. There is a small creek/drainage cut that runs on the north side of the property. This lot is mostly clear of trees on the west side of the lot. The interior of this lot and east side are covered with deciduous trees. There were no conifers recorded in this report. Methods used to determine tree location and tree health: Tree diameter was measured with a forester’s tape. Tree dripline and height and other target distances were measured with a Nikon Pro laser range finder or tape shown in Figures 1&2. Trees are tagged with Dymo Rhino aluminum labeler numerical impression and pink ribbon in Figure 3 unless otherwise noted in the Tree Assessment Matrix. All measurements and notes are recorded in digital format on site. Forest Metrix software is used to record the data and pictures to help illustrate the findings, see Site Map and Tree Assessment Matrix photos.

Discussion and Conclusion Per FWRC 19.120.130 Tree and vegetation retention standards “(1) Retention required. Existing trees and vegetation in good health, and not considered to be invasive species, shall be retained on the subject property to the maximum extent possible in all developments as follows: (a) Site and building development shall take into consideration the location of existing stands of healthy trees both on site and on adjacent properties. Where safe and feasible, the meandering of streets and/or sidewalks around existing stands of trees is encouraged. (b) Minimum tree density – New uses on vacant or redeveloping parcels. The tree density requirements will be met primarily through the conservation of existing trees. However, in order to provide for continued flexibility in the design of new development, in those situations where a development’s design would preclude the retention of the required number of trees, the use of replacement or supplemental tree planting is authorized. The minimum tree density for each land use designation is specified in Table 19.120.130-1.” Per Federal Way Revised Code (FWRC) 19.120.130 properties with a land use designation of SF Residential Zones such as this one are required a minimum tree density of 25 tree units/acre. “1) Trees that are damaged, diseased, are a hazard or nuisance or invasive species shall not be credited towards satisfying the tree units per acre requirement as noted in Table 19.120.130-1; provided, at the discretion of the city, damaged or diseased or standing dead trees may be retained and counted toward the tree requirement, if it is demonstrated that such trees will provide important wildlife habitat and are not classified as dangerous trees. 2) Trees located within critical area buffers shall be credited towards satisfying the tree units per acre requirement as noted in Table 19.120-130-1. Critical area buffers shall comply with the requirements set forth in FWRC Title 19, Division V.” The calculation of the total tree units required is as follows per FWRC 19.120.130.3&4: “(3) The total number of tree units required to be provided by a regulated activity shall be calculated by multiplying gross site acreage, minus any proposed public or private streets and regulated critical areas (excluding buffers) determined by Federal Way to be undesirable for tree planting (e.g. certain wildlife habitat and wetlands), by the required tree density (in tree units per acre) set forth in Table 19.12.0130-1. The result of the calculation will be the total number of tree units required for the activity. If the Page 48 of 53 Parcel 1196003800, Federal Way Cody Herron ABC Herron Tree LLC 425-293-2443 ISA Certified Arborist #PN-6967A Certified Tree Risk Assessor mountainredd@comcast.net calculation results in a fractional quantity, it shall be rounded up to the next higher whole number. Per the King County Assessor this parcel is 40,800 sq ft which is 0.94 of an acre (40,800 sq ft/43,560 sq ft). Per the above calculations this lot would require 24 tree units (0.94 x 25 = 23.5 rounded up). However, the area of the street that crosses this property and the area of the regulated critical areas will need to be calculated by a qualified professional and deducted from the gross site acreage, and the required tree units recalculated. (4) Tree unit credits – The number of tree unit credits given for retaining existing trees, or the planting of new trees, varies in order to encourage the retention of large existing trees and the planting of replacement trees that provide greater canopy areas at maturity. Tree unit credits for the retention of existing trees and the planting of new trees shall be awarded as follows: Figure 7 Page 49 of 53 Parcel 1196003800, Federal Way Cody Herron ABC Herron Tree LLC 425-293-2443 ISA Certified Arborist #PN-6967A Certified Tree Risk Assessor mountainredd@comcast.net Given this formula, the trees included in this report would have the following credits: Table 2 Tree Species DBH Tree Credits Tree Species DBH Tree Credits 1 Red alder 8.5 1.5 21 Red alder 15.5 2 2 Red alder 22 2.5 22 Red alder 17.5 2 3 Willow 15 2 23 Red alder 10.5 1.5 4 Red alder 33 3 24 Red alder 8.5 1.5 5 Red alder 25.6 3 25 Red alder 12 1.5 6 Bigleaf maple 13.5 2 26 Red alder 11.5 1.5 7 Red alder 13.5 2 27 Red alder 10.5 1.5 8 Black cottonwood 31.5 3 28 Red alder 17 2 9 Red alder 17.5 2 29 Red alder 9.5 1.5 10 Willow 12.5 2 30 Red alder 13 2 11 Red alder 10.5 1.5 31 Red alder 15.2 2 12 Red alder 18 2 32 Red alder 9 1.5 13 Willow 9 1.5 33 Red alder 9.5 2 14 Willow 20 2.5 34 Red alder 11 1.5 15 Red alder 9.5 1.5 35 Red alder 14 2 16 Red alder 13 2 36 Red alder 8 1.5 17 Black cottonwood 8.5 1.5 37 Red alder 13 2 18 Bigleaf maple 23 2.5 38 Red alder 14 2 19 Bigleaf maple 27.5 3 39 Red alder 15.5 2 20 Red alder 15.5 2 Total 76.5 Tree Protection Plan Per FWRC 19.120.130.7 “Tree and vegetation retention areas shall be protected during construction through application of the standards contained in FWRC 19.120.160. “19.120.160 Tree and vegetation protection during construction (1) No clearing shall be allowed on a proposed development site until the tree retention and landscape plans have been approved by the city of Federal Way. (2) A no disturbance area shall be established for each tree to be protected. The no disturbance zone shall be equal to the critical root zone which is defined as 12 inches radius for every one inch of tree diameter measured at four and one-half feet above ground. 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.

(5) If the grade level around the tree is to be raised by more than one foot, a rock well shall be constructed. The inside diameter of the rock well shall be equal to the diameter of the tree trunk plus 10 feet. Proper drainage, and irrigation if necessary, shall be provided in all rock wells. (6) The grade level shall not be lowered within the larger of the drip line of the tree(s) or the critical root zone of the tree(s). (7) No trenching is allowed in any critical tree root zone areas. (8) No installation of any impervious surfaces is allowed in critical root zones. Where road or sidewalk surfaces are needed within critical root zones, unmortared porous pavers or flagstone (rather than concrete or asphalt) may be used. Boardwalks or bridging may span root zones without harming the tree roots. (9) Tree protection areas (i.e., critical root zone) must be prepared to better withstand the stresses of the construction phase by, if necessary, fertilizing, pruning, and mulching around them well in advance of beginning any construction activities. (10) Alternative protection methods may be used if accepted by the director to provide equal or greater tree protection. (11) Encroachment into the no disturbance area may be allowed where the director determines encroachment would not be detrimental to the health of the tree.” Page 51 of 53 Parcel 1196003800, Federal Way Cody Herron ABC Herron Tree LLC 425-293-2443 ISA Certified Arborist #PN-6967A Certified Tree Risk Assessor mountainredd@comcast.net This drawing from “Managing Trees During Construction” second edition, by Kelby Fite Ph.D. and E. Thomas Smiley, Ph.D. shows two examples of tree protection fencing. Federal Way requires tree protection fencing based on DBH – for every 1 inch DBH the fence should be set 1 foot away from the trunk of the tree. Figure 8 Any major excavation or approved work near or within critical root zones of trees to be retained should be monitored by a certified arborist. This can ensure proper root pruning if necessary and encroachments that may damage or harm a protected tree’s health and vigor. Tree fencing and protection is recommended to be monitored and erected by licensed arborist. A pre-construction meeting should be established to set expectations and to answer questions about tree care. A pre-construction meeting should be held for all phases of construction with applicable contractors to discuss tree protection zones and ways to ensure trees for retention do not get damaged. Trees should be monitored during and after construction to ensure all tree protection zones are undisturbed. Should there be changes in the plan a qualified arborist should be consulted for instances such as tunneling, trenching, root pruning, prevention of soil compaction etc. Tree Planting Plan Per FWRC 19.120.130.1.b the city prefers the conservation of existing trees to meet the minimum tree unit requirements. However, due to design requirements the use of replacement or supplemental trees is allowed. Should trees be required to be replanted for this proposed development refer to the tree unit credits table in Figure 7 above.
