INTRODUCTION
You contacted me and contracted my services as a consulting arborist. My assignment is to
tag and inspect trees at the above referenced site. The purpose of this report is to establish
the condition of the significant trees to satisfy City of Renton permit submittal requirements.
I visited the site 6/23/2017 and visually inspected the regulated trees on site, which are the
subject of this report.

The parcel is currently single-family and includes a residence with a large attached
garage/shop, a large freestanding carport and three outbuildings. This report identifies and
establishes the condition of 74 existing significant trees at the project site. Of those, 23 are
unhealthy and/or located in proposed rights-of-way / access tracts, leaving 51 on-site
significant trees.
SUMMARY
The following table summarizes the tree quantities and categories inventoried in this
report. Significant, Heritage, Landmark and Dangerous categories are defined by
municipal code.
Onsite Significant Trees 39
Onsite Landmark Trees 12
Total Onsite Sig. & Land. Trees 51
Onsite Dangerous Trees /Right-of-Way Trees 23
PROPOSED RETAINED TREES 12
PROPOSED RETAINED PERCENTAGE 24%
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.

TREE IDENTIFICATION SCHEME
I marked each tree with 1” x 3.5” aluminum tag indicating tree number as listed on the
attached inventory, and as shown on the attached exhibit.
SPECIES AND SIZE OF EACH TREE
I measured the trunk diameter (54” from grade) of each tree, and identified each tree by
common name.
REASON(S) FOR TREE REMOVAL
I rated the health structure of each tree (see attached inventory). Trees with significant
visible problems or defects are indicated as Dangerous and are not viable for retention.
Removal is recommended for 7 unhealthy (Dangerous) trees, and 42 onsite trees because of
proposed site improvements. (See attachment 3.)
TREE INSPECTION METHOD – TREE HEALTH, CONDITION AND VIABILITY
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
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:
Location – indicates if tree is onsite (OS), within a private access Tract (AC), or within
the right-of-way (ROW).
Retain or Remove Tree – identifies trees proposed for retention, and indicates trees
to be removed for site improvements (SI) or if tree is unhealthy or Dangerous
(UH).
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. There are no trees on the site
planted within the most recent ten (10) years.
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 (is categorized as Dangerous and) removal is
recommended.
Visible defects Obvious structural defects or diseases visible at time of inspection,
which includes:
Asymmetric canopy– the tree has an asymmetric canopy from space and light
competition from adjacent trees.
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.
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.
Multiple 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.
Sweep in trunk – characterized by a leaning lower trunk and a more upright
top.
Stumpsprout- 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.
Trunk decay - Wood decay is visible in the trunk.
Viability - a determination by the arborist whether the tree is viable for retention.
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) or Evergreen (E).

LIMITS OF DISTURBANCE
Limits of Disturbance (LOD) are calculated for all the retained significant trees (and for trees
on adjoining parcels with overhanging driplines). They are listed below as radii in feet from
the trunk for the side of the tree to be impacted by construction. They are determined using
rootplate 3 and trunk diameter,4,5 and ISA Best Management Practices.6 These are the
minimum distances from the trees for any soil disturbance, and represent the area to be
protected during construction. These LOD are malleable and may be adjusted during the
design and construction process. The following table lists the limits of disturbance of each
tree.

TREE RETENTION PRIORITY CRITERIA
Trees are indicated according to Priority One criteria as provided in RMC §4-4-130H.1.b. in
the attached inventory.
TREE RETENTION AND LAND CLEARING REGULATIONS from RMC.
§4.4.130 H.9. Protection Measures During Construction: Protection measures in this
subsection shall apply for all trees that are to be retained. All of the following tree
protection measures shall apply:
a. Construction Storage Prohibited: The applicant may not fill, excavate, stack or
store any equipment, dispose of any materials, supplies or fluids, operate any
equipment, install impervious surfaces, or compact the earth in any way within
the area defined by the drip line of any tree to be retained.
b. Fenced Protection Area Required: Prior to development activities, the applicant
shall erect and maintain six-foot (6') high chain link temporary construction
fencing around the drip lines of all retained trees or at a distance surrounding
the tree equal to one and one-quarter feet (1.25') for every one inch (1") of
trunk caliper, whichever is greater, or along the perimeter of a tree protection
tract. Placards shall be placed on fencing every fifty feet (50') indicating the
words, “NO TRESPASSING – Protected Trees,” or on each side of the fencing if

trees shall be fenced and signed. Individual trees shall be fenced on four (4)
sides. In addition, the applicant shall provide supervision whenever equipment
or trucks are moving near trees.
c. Protection from Grade Changes: If the grade level adjoining to a tree to be retained
is to be raised, the applicant shall construct a dry rock wall or rock well around
the tree. The diameter of this wall or well must be equal to the tree’s drip line.
d. Impervious Surfaces Prohibited within the Drip Line: The applicant may not install
impervious surface material within the area defined by the drip line of any tree
to be retained.
e. Restrictions on Grading within the Drip Lines of Retained Trees: The grade level
around any tree to be retained may not be lowered within the greater of the
following areas: (i) the area defined by the drip line of the tree, or (ii) an area
around the tree equal to one and one-half feet (1-1/2') in diameter for each
one inch (1") of tree caliper. A larger tree protection zone based on tree size,
species, soil, or other conditions may be required. (Ord. 5676, 12-3-2012)
f. Mulch Layer Required: All areas within the required fencing shall be covered
completely and evenly with a minimum of three inches (3") of bark mulch prior
to installation of the protective fencing. Exceptions may be approved if the
mulch will adversely affect protected ground cover plants. (Ord. 5676, 12-3-
2012)
g. Monitoring Required during Construction: The applicant shall retain a certified
arborist or licensed landscape architect to ensure trees are protected from
development activities and/or to prune branches and roots, fertilize, and water
as appropriate for any trees and ground cover that are to be retained.
h. Alternative Protection: Alternative safeguards may be used if determined to
provide equal or greater tree protection. (Ord. 5676, 12-3-2012)

Attachment No. 1 - Assumptions & Limiting Conditions
1. A field examination of the site was made 6/23/2017. 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. A complete evaluation of the
potential for this (a) tree to fail requires excavation and examination of the base of
the subject tree.
7. The consultant shall not be required to give testimony or to attend court by reason of
this report unless subsequent contractual arrangements are made.
8. 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.
