ISA Tree Risk Assessment Qualified
ASCA Registered Consulting Arborist® #379
Gina Brooks of Core Design contacted me on your behalf and you subsequently contracted my
services as a consulting arborist. My assignment is to inspect trees at the above referenced site.
The purpose of this report is to establish the condition of the significant trees to be used as part
of a City required mitigation plan.
I received a site plan from Core Design, and I visited your home on 4/29/2022 and visually
inspected all the regulated trees on your parcel, which are the subject of this report.
SUMMARY
The following table summarizes the tree quantities and categories inventoried in this report.
Significant, Landmark and Dangerous categories are defined by municipal code. Dead trees are
excluded from this report.
Significant Trees on Site 96
Landmark Trees on Site 35

Limitations and Use of this Report
This tree report establishes, via the most practical means available, the existing conditions
of the trees on the subject property. 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.
SPECIES AND SIZE OF EACH TREE
I measured the trunk diameter of each tree 54” from grade, except for recently planted trees
that are reported using a caliper measurement. I identified each tree by common name.
IDENTIFICATION SCHEME
The survey provided me by Core Design showed symbols and locations for 99 trees (numbered
1-99) all upon the referenced parcel. In addition to these trees, I added to this sheet 48 trees
that were not included (numbered 101-148). These added trees comprise fruit trees planted by
you within the past few years, and also trees that were likely too small at the time of the survey,
and were not regulated at that time.1
TREE INSPECTION METHOD – TREE HEALTH, CONDITION AND VIABILITY
I visually inspected each tree from the ground. I performed a Level 1 risk assessment.2 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.
1 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"). Trees qualified as dangerous shall not be considered significant. Trees planted within the
most recent ten (10) years shall qualify as significant trees, regardless of the actual caliper.

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.3
No invasive procedures were performed on any trees. The results of this inspection are based
on what was visible at the time of the inspection.
The attached inventory summarizes my inspection results and provides the following
information for each tree:
Proposed Action – Indicates if tree is to be removed or retained.
Tree Category as defined by municipal code. (TREE: A woody perennial usually having
one dominant trunk, or, for certain species, a multi-stemmed trunk system, with a
potential minimum height of ten feet (10') at maturity. Any trees listed on the Complete
King County Weed List shall not qualify as a tree.)
Dangerous: Any tree that has been certified, in a written report, as dead, terminally
diseased, damaged, or otherwise dangerous to persons or property by a licensed
landscape architect, or certified arborist.
Landmark: A tree with a caliper of thirty inches (30") or greater. (Average multiple
stems and report single integer)

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"). Trees qualified as dangerous shall
not be considered significant. Trees planted within the most recent ten (10)
years shall qualify as significant trees, regardless of the actual caliper.
Tree number as shown on tag in the field, and on attached exhibit.
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.
Health and Structure ratings ‘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 and tree removal is recommended.
Comments on Condition Obvious structural defects or diseases visible at time of
inspection, which might include:
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.
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 microorganisms resulting in weak and
defective structure.
Diseased – foliage and trunk/stems are diseased.
Disease center – soil borne fungal infection site.
Dogleg in trunk – trunk with a bow or defective bend (90°) in trunk often half way
of further up the trunk.
Double leader – the tree has multiple stem attachments, which may require
maintenance or monitoring over time.
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 leaders - the tree has multiple stem attachments, which may lead to
tree failure and require maintenance or monitoring over time.
Poor structure – tree’s structure is deformed and defective/unsightly

Previous failure – Tree trunk previously broken and defective.
Slender – tree lacks adequate trunk taper to stand lone.
Stem Canker – disease canker on trunk/branches.
Thinning Canopy – low foliage density may indicate stress, or early
infection/declining health.
Self-corrected lean - Self-corrected leans and sweeps are characterized by a
leaning lower trunk and a top that is more upright.
Stump sprout- Tree previously cut at grade with multiple stems and potentially
weak attachments.
Suppressed – tree crowded by larger adjacent trees, with defective structure
and/or low vigor. Retain tree only as a grove tree, not stand-alone.
Sweep – tree leans away from adjacent trees. Characterized by a leaning lower
trunk and a top that is more upright.
Topped – the tree is previously topped and has poor structure and/or stem
decay.
Tree leans – Trunk has significant lean from vertical.
Tree suppressed - Tree is suppressed by adjacent tree canopies.
Trunk decay - Wood decay is visible in the trunk.
Wound/decay base of trunk - Open wound with visible decay in trunk.
Retention Priority Criteria – indicates if tree is Landmark, >60’ tall, part of a continuous
canopy, >18” DBH, or is non-native.
Type indicates if tree is Deciduous (D), Evergreen (E), broadleaf (B) and coniferous (C).
SUBJECT TREES
The subject trees are predominantly native species, and mostly Douglas-fir, Bigleaf maple and
Western red-cedar in naturally wooded areas at the east and west sides of the subject parcel.
There are a few ornamental and fruit species, and most of the latter are saplings only recently
planted.
A few of the trees are considered dangerous by code definition, but pose little risk to high value
structures or targets. Risk reduction and mitigation is excluded from this report.

Attachment No. 1 - Assumptions & Limiting Conditions
1. A field examination of the site was made 4/29/2022. 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 land surveyor. Reasonable care was used to match the trees
indicated on the sheets with those growing in the field.
4. 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.
5. 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.
6. All trees possess the risk of failure. Trees can fail at any time, with or without obvious
defects, and with or without applied stress. Risk reduction and mitigation is excluded
from this report. Trees identified as dangerous in this report are established as such by
meeting the definition in municipal code, and not a basic or an advanced risk
assessment. Removal or retention of dangerous trees requires an advanced risk
assessment, which is outside the scope of this report.
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.
