My assignment is to inspect and assess the condition of surveyed trees at the above referenced site. I received a topographic survey of the site from DR Strong Consulting Engineers, showing the locations of the surveyed trees. I visited the site on 10/15/15 and inspected the trees, which are the subject of this report. Neither parcel is developed. The site has a SW aspect with a stream delineated through the center of the site, east to west. Both parcels are covered in native vegetation, predominately deciduous tree species with moderate to dense lower understory. TREE INSPECTION My inspection is limited to visual observation from the subject parcels and the rights-‐of-‐way. Both health and structure were evaluated. A tree’s structure is distinct from its health. Structure is the way the tree is put together or constructed, and identifying obvious defects can be helpful in determining if a tree is predisposed to failure. Health addresses disease and insect infestation. No invasive procedures were performed on any trees. The results of this inspection are based on what is visible at the time of the inspection. I identified the species of each tree, confirmed trunk diameter (DBH), estimated average dripline and rated the condition of each tree. Bigleaf maples on this site have a wide age and size range. The largest and oldest maple trees are generally in the poorest condition. A handful of bitter cherry are scattered throughout the site, and all are viable. Black cottonwoods dominate the site in numbers, and there are far more younger cottonwoods than older. The oldest and larger trees are in better condition overall. Many of cottonwoods as edge trees lean excessively away from the stand. Nearly all the smaller cottonwoods are very slender. Although they are healthy and have no visible defects, their trunks are too tall for Justin Lagers, Avana Ridge, LLC RE: Tree Inspection; Avana Ridge PPUD, Parcel Nos. 292305-‐9148, -‐9009; Renton WA December 16, 2015 Page 2 of 24 Greenforest Registered Consulting Arborist their girth, and they cannot be retained as stand-‐alone trees or even in small groups without an increased risk of failure. A few Oregon white ash, madrone, alder and willow are scattered among the cottonwoods. And only 12 conifers grow on the site; hemlock, fir and cedar, and all are relatively small, young trees. The table below summarizes the total trees by species, and by Dangerous or Viable. Species Douglas-‐fir 6 Black cottonwood 284 Bigleaf maple 109 Scouler's willow 6 Western red-‐cedar 4 Bitter cherry 11 Red alder 5 Oregon white ash 1 Western hemlock 2 Pacific madrone 1 429 Dangerous Trees 97 Viable Trees 332 429 The attached inventory summarizes my inspection results and provides the following information for each tree: Tree number as shown on the attached survey. DBH Stem diameter in inches measured 4.5 feet from the ground. Tree Species Common name. Dripline Average branch extension from the trunk as radius in feet. Tree Class Tree, Significant: A tree with a caliper of at least six inches (6"), or an alder or cottonwood tree with a caliper of at least eight inches (8"). Tree, Landmark: A tree with a caliper of thirty inches (30") or greater. Structure and Health rating ‘1’ indicates no visible health-‐related problems or structural defects, ‘2’ indicates minor visible problems or defects that may require attention if the tree is retained, and ‘3’ indicates significant visible problems or defects. Trees rated a 1 or 2 are considered viable. Trees rated a 3 are considered dangerous (see below).

Tree, Dangerous: Any tree that has been certified via this report as dead, terminally diseased, damaged, or otherwise dangerous to persons or property; and for healthy trees, a determination whether the tree is viable for retention. Visible defects Obvious structural defects or diseases visible at time of inspection. Asymmetric canopy– the tree has an asymmetric canopy from space and light competition from adjacent trees. Branch dieback -‐ Mature branches in canopy are dying/dead; overall low tree vigor, Bow in trunk – a trunk lean characterized by the top of the tree leaning over. (Common with edge trees) Crack – separation of wood fibers and predisposed to failure. Dead – tree is dead. Deadwood – Large and/or multiple dead branches throughout canopy. Decay – process of wood degradation by micro-‐organisms resulting in weak and defective structure. Diseased – foliage and trunk/stems are diseased. Dogleg in trunk – trunk with a bow or defective bend (90°) in trunk often half way of further up the trunk. Foliar disease -‐ Foliage is diseased with manageable fungus. Ivy -‐ Dense ivy prevents a thorough inspection, and other defects may be present. Lean – Angle of the trunk from vertical. Multiple (double) leaders -‐ the tree has multiple stem attachments, which may lead to tree failure and require maintenance or monitoring over time. Previous failure – Tree trunk previously broken and defective. Suppressed – tree crowded by larger adjacent trees; with defective structure and/or low vigor. Retain tree only as a grove tree, not stand-‐alone. During my fieldwork, I numbered the trees sequentially as I inspected them, and then annotated a clean sheet using Adobe Acrobat text tool. The numbers in this report are typed over the corresponding tree symbol on the survey. Trees marked XX are dead, fallen over or gone, and are not included in this report (even though some other dead trees are). TS indicates a tree to small to be considered significant, and these trees were not added to the inventory. Trees I added to the inventory, and that were not shown in the survey, are indicated by an asterisk preceding the number. Approximately 36 of the subject trees are on adjoining rights-‐of-‐way.

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) I am not a qualified surveyor, and although considerable effort was made to match the trees on the site with those shown on the survey, I cannot guarantee the accuracy. 4) 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 from the subject property, 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. 5) All trees possess the risk of failure. Trees can fail at any time, with or without obvious defects, and with or without applied stress. A complete evaluation of the potential for the subject trees to fail requires excavation and examination of the base of the tree. Permission of the adjoining property owner must be obtained before this work can be undertaken and a risk assessment completed. 6) Construction activities can significantly affect the condition of retained trees. All retained trees should be inspected after construction is completed, and then inspected regularly as part of routine maintenance. 7) 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. 8) Loss or alteration of any part of this report invalidates the entire report. 9) 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. 10) This report and any values/opinions expressed herein represent the opinion of the consultant/appraiser, and the consultant’s/appraiser’s fee is in no way contingent upon the reporting of a specified value, a stipulated result, the occurrence of a subsequent event, nor upon any finding to be reported. 11) Ownership and use of consultant’s documents, work product and deliverables shall pass to the Client only when ALL fees have been paid.

The numbers in this report are typed over the corresponding tree symbol on the survey. Trees marked XX are dead, fallen over or gone, and are not included in this report (even though some other dead trees are). TS indicates a tree to small to be considered significant, and these trees were not added to the inventory. Trees I added to the inventory, and that were not shown in the survey, are indicated by an asterisk preceding the number. Approximately 36 of the subject trees are on adjoining rights-of-way.Justin Lagers, Avana Ridge, LLCRE: Tree Inspection; Avana Ridge PPUD, Parcel Nos. 292305-9148, -9009; Renton WADecember 16, 2015Page 24 of 24Attachmeent No. 3 - Tree Number Exhibit
