1. Introduction
American Forest Management was contacted by RJ Development LLC and was asked to
compile an ‘Arborist Report’ for a development on Talbot Road S in the City of Renton.
The parcel numbers are #3123059067 & #3123059094.
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: .................................................... Several days in November 2017
2. Description
306 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 10 years qualify as significant trees, regardless of the
actual caliper. There are also two neighboring trees that may be impacted by the
proposed development. These two trees were included in this report.
All subject trees have been identified 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:
December 4th, 2017 Talbot Rd S - Renton
Page 3
AMERICAN FOREST MANAGEMENT, INC.
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. The proposed development area is primarily comprised of native
hardwood species with some scattered coniferous trees. Willow and black cottonwood are
the dominant species in the study area. There is a moderate component of big leaf maple
and Douglas fir. There is a very minor amount of other species, including red alder, bitter
cherry and cascara.
Black cottonwood
The black cottonwood trees vary in age and condition. Most are in groupings on the south
west portion of the property. Many noteworthy defects were observed in the black
cottonwood, such as leaning trunks, poor branch attachments and stem decay. Some of the
cottonwoods are suppressed from heavy competition with adjacent trees. These
suppressed trees are likely to have internal stem decay. The black cottonwood trees range
in viability.
Willow
The conditions of the site are moist and Scouler pussy willows were found throughout the
flat portions of the property. Most are mature and have severe decay. The most common

defect was trunk decay. This is was observed in most of the significant willow trees on the
property. The second most common defect was severe leans, where one or more of the
trunks is leaning over 45 degrees. The willows range in condition from fair to poor.
Viability varies.
Big leaf maple
The big leaf maple trees range in age and were found throughout the property. Most are
healthy and viable. The majority have co-dominant trunks. The most common defects
observed were poor attachments between co-dominant trunks, dead branches, and
asymmetrical crowns. 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 30 years old on the property. Most have good taper and full
crowns. The most common defect observed was forked trunks. Tree #214 has a
Porodaedalea pini conk on the trunk. This tree has a full crown but the presence of the conk
indicates that the tree is in poor condition and is non-viable. Overall, most of the Douglas
fir trees are in good condition and are viable.
Neighboring Trees
Tree #501 is a black cottonwood tree north of the property line. This tree is in fair
condition and is viable. The drip-line of this tree does not cross the property line.
Tree #502 is a big leaf maple just north of the property line. The subject tree is semi-
mature and is in good condition. This tree is 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. This has also been delineated on the
Tree Protection Map for retained trees near the proposed impacts. The information
plotted on the attached survey plan may need to be transferred to a final tree
retention/protection plan to meet City submittal requirements. The trees that are to be
removed shall be shown “X’d” out on the final plan.
The Limits of Disturbance (LOD) measurements can also be found on the tree summary
table. These have also been delineated for retained trees near proposed impacts on the
Tree Protection Maps. 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.
Tree #214 has a large Porodaedalea pini, red ring rot, conk on the trunk. Red ring rot wood
decay disease of the inner wood of conifers. This tree is on the west side of the property,
where the development will occur and will be removed. No other obviously infected trees
were observed.
Black cottonwood is a pioneer species that grows fast and vigorously. Typically black
cottonwoods live to 100 years or so. Maturity often hits around age 60 to 70 then decline
December 4th, 2017 Talbot Rd S - Renton

AMERICAN FOREST MANAGEMENT, INC.
follows. Complete crown failure and loss of large limbs is common in black cottonwoods due to
inherently weak branch attachments and brittle wood. Trees with co-dominant stems and
noteworthy included bark are especially at risk. Many previous branch failures were
observed at the site. The long term viability of the cottonwood on the site is questionable. All
of the black cottonwoods proposed for retention are at least 50' from the new development.
The short lived hardwood species such as willows, black cottonwoods, red alders and bitter
cherry are low priority for retention. Retention efforts will be focused on the healthy big leaf
maple and Douglas fir trees.
A follow-up tree risk assessment of the retained trees is recommended prior to final
completion or occupancy of the site to identify any potentially hazardous conditions and to
maintain risks at acceptable levels.
6. Tree Retention
A total of 306 significant trees were identified on the subject property. Trees in poor
condition were not included in the tree calculation. The City of Renton requires retention of
10% of all the viable significant trees on commercial sites.
Tree Calculation based on 252, healthy, viable, significant trees
Viable Trees proposed for removal – 209 (83%)
Viable Trees proposed for retention – 43 (17%)
7. Tree Replacement
No replacement trees will be required. New trees plantings would enhance the site. For
planting and maintenance specifications, refer to Section 4-4-130 of the Renton Tree
Ordinances.

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.
