1. Introduction
American Forest Management was contacted by KP Development Group and was asked
to compile an ‘Arborist Report’ for a development at 1825 NE 38th St in the City of
Renton. The parcel number is #3345700220.
Our assignment is to prepare a written report on the current condition of significant trees
on the subject parcels and any right-of-way or neighboring trees that may be impacted
by the future development of the property.
Date of Field Examination: .......................................................... February 23rd and 26th, 2018
2. Description
128 significant trees were identified on the property. According to City of Renton code, a
significant tree is a tree with a caliper (trunk diameter measured 4-1/2’ above the
ground) of at least 6” or an alder or cottonwood tree with a caliper of at least 8”. Trees
planted within the most recent ten years qualify as significant trees, regardless of the
actual caliper. There are also 12 neighboring trees that may be impacted by the
proposed development. These 12 trees were included in this report.
All subject trees have been identified by the surveyor with a white piece of flagging with
a number written on it. Significant trees that were not surveyed were approximately
located and tagged with a numbered aluminum tag attached to the lower trunk of the
tree. Field tree tag numbers correspond with attached Tree Condition Summary Table
and attached copy of the site survey. The tree summary table provides descriptive data
for all assessed trees, including drip-line measurements.
3. Methodology
Each tree in this report was visited. Tree diameters were measured by tape. The tree
heights were measured using a Spiegel Relaskop. Each tree was visually examined for
defects and vigor. The tree assessment procedure involves the examination of many
factors:
The crown of the tree is examined for current vigor. This is comprised of
inspecting the crown (foliage, buds and branches) for color, density, form, and
annual shoot growth, limb dieback and disease. The percentage of live crown is
estimated for coniferous species only and scored appropriately.
The bole or main stem of the tree is inspected for decay, which includes cavities,
wounds, fruiting bodies of decay (conks or mushrooms), seams, insects, bleeding,
callus development, broken or dead tops, structural defects and unnatural leans.
Structural defects include crooks, forks with V-shaped crotches, multiple
attachments, and excessive sweep.
The root collar and roots are inspected for the presence of decay, insects and/or
damage, as well as if they have been injured, undermined or exposed, or
original grade has been altered.

Based on these factors a determination of condition is made. The four condition
categories are described below based on the species traits assessed:
Excellent – free of structural defects, no disease or pest problems, no root issues, excellent
structure/form with uniform crown or canopy, foliage of normal color and density, above
average vigor, it will be wind firm if isolated, suitable for its location
Good – free of significant structural defects, no disease concerns, minor pest issues, no
significant root issues, good structure/form with uniform crown or canopy, foliage of
normal color and density, average or normal vigor, will be wind firm if isolated or left as
part of a grouping or grove of trees, suitable for its location
Fair – minor structural defects not expected to contribute to a failure in near future, no
disease concerns, moderate pest issues, no significant root issues, asymmetric or
unbalanced crown or canopy, average or normal vigor, foliage of normal color, moderate
foliage density, will be wind firm if left as part of a grouping or grove of trees, cannot be
isolated, suitable for its location
Poor – major structural defects expected to fail in near future, disease or significant pest
concerns, decline due to old age, significant root issues, asymmetric or unbalanced crown
or canopy, sparse or abnormally small foliage, poor vigor, not suitable for its location
A ‘viable’ tree is a significant tree that a qualified professional has determined to be in
good health, with a low risk of failure due to structural defects, is wind firm if isolated or
remains as part of a grove, and is a species that is suitable for its location. Trees
considered ‘non-viable’ are trees that are in poor condition due to disease, age related
decline, have significant decay issues and/or cumulative structural defects, which
exacerbate failure potential.
The attached tree map indicates the ‘condition’ of the subject trees found at the site.
4. Observations
General species concerns are described below. For information on specific trees, see the
attached tree table.
Big leaf maple
Big leaf maple is the most common species on the property. Most are healthy and viable.
The majority have co-dominant trunks which is typical for the species. The most common
defects observed were poor attachments between co-dominant trunks, dead branches,
and asymmetrical crowns. Ivy is growing up the trunks of most of the trees. For some of the
big leaf maples, the entire trunks is covered in ivy. The big leaf maple trees range in
condition from poor to good.
Douglas fir
There are many mature (over 80 years old) Douglas fir trees. They are located throughout
the property. No natural regeneration of Douglas fir trees is occurring and there are very
few Douglas fir trees under 20 years old on the property. Most have good taper and full
crowns. The most common concerns were structural issues such as forked tops, crooked

trunks or asymmetrical crowns. English ivy is growing up the trunks of most of the Douglas
fir trees on the property. Overall, most of the Douglas fir trees are in good condition and
are viable.
Western red cedar
The majority of Western red cedar trees on the property are healthy and viable. Most
have good trunk taper and full crowns. Ivy is growing up the trunks of all of the Western
red cedars. Tree #1099 is a young Western red cedar. The top half of this tree is dead.
This tree is in poor condition and is non-viable. With the exception of tree #1099, all of
the Western red cedar trees on the property are viable.
Sitka spruce
There are some young and semi-mature Sitka spruce trees in the southwest area of the
property. Ivy growing up the trunks of these trees. Conditions range from fair to good. All
are viable.
Leyland cypress
There are Leyland cypress trees that were planted on the south perimeter of the property.
Most have forked tops and two are leaning south. Conditions range from fair to good. All
are viable.
Cascara
There are four cascara trees scattered on the east side of the lot. They are all over-
mature. One tree, #876, has severe decay and is on poor condition. The other three are
and fair condition and are viable.
Red alder
Red alder is a minor species on the property. The most common concern is leaning trunks
with poor trunk taper. The red alders range in condition. Ivy is growing up the trunks of
most of the trees. Tree #1235 is in poor condition. This tree has a small live crown and
decay. The other red alder trees on the subject property are in fair condition and are
viable.
5. Discussion
The extent of drip-lines (farthest reaching branches) for the subject trees can be found on
the tree summary table at the back of this report. The Limits of Disturbance (LOD)
measurements can also be found on the tree summary table. The LOD measurements are
based on species, age, condition, drip-line, prior improvements, proposed impacts and the
anticipated cumulative impacts to the entire root zone. These should be referenced when
determining retention feasibility.
The City of Renton code requires that tree retention priority should be focused on
landmark trees and significant trees that form a continuous canopy. There are eight
landmark trees on the subject property. The City of Renton defines a landmark tree with a
trunk greater than 30" at 4.5' above ground. The attached tree table notes which trees
qualify as landmark trees. The short lived hardwood species such as red alder and
cascara are low priority for retention. Retention efforts should be focused on the healthy
big leaf maple, Western red cedar and Douglas fir trees.

The entire property has any ivy infestation. Ivy becomes a problem for trees when it
grows to a large size and grows up into the tree crown. The leaves of the ivy cover
branches inhibiting the development of tree leaves and thereby reducing the trees
photosynthetic processes, causing stress and ultimately decline. The weight of the ivy is
also problematic. Oftentimes, the weight of the ivy will cause stems or branches to fail
when they become over-loaded and cannot support the additional weight. A few trees in
the study area have recently failed from being over-loaded by the weight of the ivy. The
probability of more failures is high. If left alone, the ivy will eventually over take the
subject trees, causing them all to fail prematurely.
If the subject trees are to be maintained in the landscape for another 20 years or so, the
ivy will need to be cut away from the trees. To kill the ivy vines, the vines are cut back
from the base of the tree a few feet. Then the ivy is cut a few feet up the tree trunk,
removing the cut portions. Once the ivy is severed, it will die. The ivy will eventually decay
and fall out of the trees. Given the current infestation, this will take a few years. As much
of the ivy as possible should be pulled off of the trees to remove additional weight,
thereby increasing structural stability.
6. Tree Retention
A total of 128 significant trees were identified on the subject property. The City of Renton
requires retention of 30% of all the viable significant trees on R-8 zoned sites. The six trees in
poor condition were not included in the calculation.
Trees in Critical Areas and buffers as defined in RMC 4-3-050 are excluded from the
retention calculation. According to the site map provided by the Client 20 trees are located in
the 25 foot buffer and Critical Area. Including the 6 trees in poor condition, a total of 26
trees were excluded from the retention calculation.
Trees 922, 998, 1055, 1056, 1044, and 1061 are identified as Landmark Trees and are not
proposed for retention.
Tree Calculation based on 102 healthy, viable trees outside of Critical Areas and Buffers
Minimum amount of trees that must be retained on site: 31 trees.
7. Tree Replacement
For planting and maintenance specifications, refer to Section 4-4-130 of the Renton Tree
Ordinances.
Total number of healthy, viable trees, outside of Critical Areas and buffers that are proposed
to be reatined: 17 trees.
Total number of trees to be replaced: 31 - 17 = 14 trees.
Total number of required replacement inches: 14 x 12 = 163 inches
Number of replacement trees required (Minimum of 2" caliper trees required for
replacement): 163 / 2 = 82 trees (Rounded up from nearest tenth)
February 28th, 2018; Updated 10/8/2018 1825 NE 38th St - Renton

AMERICAN FOREST MANAGEMENT, INC.
The number of replacement trees could change depending on the caliper of trees selected
for replacement.
8. Tree Protection Measures
The following guidelines are recommended to ensure that the designated space set aside
for the preserved trees are protected and construction impacts are kept to a minimum.
Refer to the City of Renton Code 4-4-130- 9. Protection Measures During Construction for
more information. They are also included at the end of this report.
Tree protection barriers shall be initially erected at 5’ outside of the drip-line
prior to moving any heavy equipment on site.
Tree protection fencing shall only be moved where necessary to install
improvements, but only as close as the Limits of Disturbance, as indicated on the
attached plan.
Excavation limits should be laid out in paint on the ground to avoid over
excavating.
Excavations within the drip-lines shall be monitored by a qualified tree
professional so necessary precautions can be taken to decrease impacts to tree
parts. A qualified tree professional shall monitor excavations when work is
required and allowed up to the “Limits of Disturbance”.
To establish sub grade for foundations, curbs and pavement sections near the
trees, soil should be removed parallel to the roots and not at 90 degree angles
to avoid breaking and tearing roots that lead back to the trunk within the drip-
line. Any roots damaged during these excavations should be exposed to sound
tissue and cut cleanly with a saw. Cutting tools should be sterilized with alcohol.
Areas excavated within the drip-line of retained trees should be thoroughly
irrigated weekly during dry periods.
Preparations for final landscaping shall be accomplished by hand within the
drip-lines of retained trees. Plantings within the drip lines shall be limited.
Large equipment shall be kept outside of the tree protection zones.
There is no warranty suggested for any of the trees subject to this report. Weather, latent
tree conditions, and future man-caused activities could cause physiologic changes and
deteriorating tree condition. Over time, deteriorating tree conditions may appear and there
may be conditions, which are not now visible which, could cause tree failure. This report or
the verbal comments made at the site in no way warrant the structural stability or long term
condition of any tree, but represent my opinion based on the observations made.
Nearly all trees in any condition standing within reach of improvements or human use areas
represent hazards that could lead to damage or injury.
Please call if you have any questions or if we can be of further assistance.
Sincerely,
February 28th, 2018; Updated 10/8/2018 1825 NE 38th St - Renton
