[PHONE REDACTED] TO: Tejal Pastakia Boxspring Redmond, LLC 94 Pike Street Seattle WA 98101 REFERENCE: Redmond Way Flats Tree Health Report SITE ADDRESS: 16760 Redmond Way, Redmond WA DATE: March 12, 2018 PREPARED BY: Favero Greenforest, ISA Certified Arborist # PN -0143A ISA Tree Risk Assessment Qualified ASCA Registered Consulting Arborist® #379 You contacted me and contracted my services as a consulting arborist. My assignment is to inspect the regulated trees at the above referenced site. The purpose of this report is to establish the condition of the subject trees to satisfy City of Redmond permit submittal requirements. You provided me a topographic survey, and I visited the site 2/21/2018 and visually inspected the regulated trees on the site, which are the subject of this Tree Health report. The following table summarizes the tree quantities and categories inventoried in this report. Significant, Landmark and Unhealthy categories are defined by municipal code. SUMMARY: Total Significant Trees on Site 17 Total Landmark Trees on Site 0 Total Regulated Trees on Site 17 Unhealthy Trees 0 Offsite Trees 0 Right-of-way Trees 4 ---PAGE BREAK--- Tejal Pastakia, Boxspring Redmond, LLC RE: Redmond Way Flats Tree Health Report March 12, 2018 Page 2 of 8 Greenforest Registered Consulting Arborist TREE INSPECTION METHOD I visually inspected each tree from the ground. I performed a Level 1 risk assessment.1 This is the standard assessment for populations of trees near specified targets, conducted in order to identify obvious defects or specified conditions such as a pre-development inventory. This is a limited visual assessment focuses on identifying trees with imminent and/or probable likelihood of failure, and/or other visible conditions that will affect tree retention. I recorded tree species and size (DBH). I estimated the average dripline of each tree. I rated the condition of each tree, both health and structure. A tree’s structure is distinct from its health. This inspection identifies what is visible with both. High-risk trees can appear healthy in that they can have a dense, green canopy. This may occur when there is sufficient sapwood or adventitious roots present to maintain tree health, but inadequate strength for structural support. Conversely, trees in poor health may or may not be structurally stable. For example, tree decline due to root disease is likely to cause the tree to be structurally unstable, while decline due to drought or insect attack may not. One way that tree health and structure are linked is that healthy trees are more capable of compensating for structural defects. A healthy tree can develop adaptive growth that adds strength to parts weakened by decay, cracks, and wounds. This report identifies unhealthy trees based on existing health conditions and tree structure, and specifies which trees are most suitable for preservation.2 I marked the onsite regulated trees with a 1” x 3” aluminum tag prior to my inspection. The attached tree inventory contains the following information on each tree. Proposed Action – indicates if tree is to be retained, impacted or removed. (All onsite trees are proposed for removal.) Tree Category indicates if tree is Significant or greater DBH) or Landmark (greater than 30” DBH), or is Unhealthy. Tree number as indicated on tag in field (for onsite trees) and shown on the attached site plan. DBH Stem (trunk) diameter in inches 4.5 feet from grade. 1 Companion publication to the ANSI A300 Part 9: Tree Shrub and Other woody Plant Management – Standard Practices, Tree Risk Assessment. 2011.

Dripline Average branch extension in feet as radius from the trunk. Health and Structure rating indicates good to excellent condition; no visible health-related problems or structural defects, indicates fair condition; minor visible problems or defects that may require attention if the tree is retained, and indicates poor condition; significant visible problems or defects: the tree is considered unhealthy, the tree is not regulated, and removal is recommended. Comments on Health Obvious structural defects or diseases, tree form or other tree attributes visible at time of inspection. TREE RETENTION & REPLACEMENT All regulated trees on the site are proposed for removal. There are no impacted or retained trees. Regardless of the percentage of removed trees, mitigation, i.e. replacement trees at a ratio of 1:1, are required for each removed tree. The total significant trees proposed for removal are 17, which is the required quantity of replacement trees. (Right-of-way tree are not included in this calculation.) SUMMARIZING COMPLIANCE WITH CODE. The following table provides you with the format that is required for summarizing a proposal’s conformance with the City’s tree protection regulations. The table must appear in the Arborist Report and on the Tree Preservation Plan, both of which are part of the application.

Ratings for health and structure, as well as any recommendations are valid only through the development and construction process. This report is based solely on what is readily visible and observable, without any invasive means. There are several conditions that can affect a tree’s condition that may be pre-existing and unable to be ascertained with a visual-only analysis. No attempt was made to determine the presence of hidden or concealed conditions which may contribute to the risk or failure potential of trees on the site. These conditions include root and stem (trunk) rot, internal cracks, structural defects or construction damage to roots, which may be hidden beneath the soil. Additionally, construction and post-construction circumstances can cause a relatively rapid deterioration of a tree’s condition. ATTACHMENTS: 1. Assumptions and Limiting Conditions 2.

My observations and conclusions are as of that date. 2) Care has been taken to obtain all information from reliable sources. All data has been verified insofar as possible; however, the consultant/arborist can neither guarantee nor be responsible for the accuracy of information provided by others. 3) Unless stated other wise: 1) information contained in this report covers only those trees that were examined and reflects the condition of those trees at the time of inspection; and 2) the inspection is limited to visual examination of the subject trees without dissection, excavation, probing, or coring. There is no warranty or guarantee, expressed or implied that problems or deficiencies of the subject tree may not arise in the future. 4) The consultant/appraiser shall not be required to give testimony or to attend court by reason of this report unless subsequent contractual arrangements are made. 5) Loss or alteration of any part of this report invalidates the entire report. 6) Unless required by law otherwise, possession of this report or a copy thereof does not imply right of publication or use for any purpose by any other than the person to whom it is addressed, without the prior expressed written or verbal consent of the consultant/appraiser. 7) The subject right-of-way trees are assumed to be city owned. I am not a qualified land surveyor, and no such professional was obtained to determine the exact location of the subject tree. 8) Construction activities can impact trees in unpredictable ways. All retained trees should be inspected at the completion of construction, and regularly thereafter as part of ongoing maintenance. 9) The consultant does not assume any liability for the subject tree and does not represent the transfer of such for any risks associated with the tree from the landowner to the consultant. Risk management is solely the responsibility of the landowner. ---PAGE BREAK--- Tejal Pastakia, Boxspring Redmond, LLC RE: Redmond Way Flats Tree Health Report March 12, 2018 Page 6 of 8 Greenforest Registered Consulting Arborist Attachment No. 2 - Certification of Performance I, Favero Greenforest, certify that: • I have personally inspected the trees and the property referred to in this report and have stated my findings accurately. • I have no current or prospective interest in the vegetation or the property that is the subject of this report and have no personal interest or bias with respect to the parties involved. • The analysis, opinion, and conclusions stated herein are my own and are based on current scientific procedures and facts. • My analysis, opinion, and conclusions were developed and this report has been prepared according to commonly accepted arboricultural practices. • No one provided significant professional assistance to me, except as indicated within the report. • My compensation is not contingent upon the reporting of a predetermined conclusion that favors the cause of the client of any other party nor upon the results of the assessment, the attainment of stipulated results, or the occurrence of any subsequent events.
