Assignment
Layton Tree Consulting, LLC was asked to compile an Arborist Report for a property in Renton, located at
11806 SE 192nd Street. The purpose of the report is to satisfy City requirements regarding tree retention
regulations associated with the proposed re-development of the property.
My assignment is to prepare a written report on present tree conditions, and to provide appropriate
recommendations for the protection of retained or protected trees during development.
This report covers all of the criteria set forth under the City of Renton’s tree regulations, Municipal Code
Section 4-4-130 - Tree Retention and Land Clearing Regulations. Properties subject to an active land
development permit shall retain a minimum of thirty percent (30%) of all significant trees on site.
Date of Field Examination: March 21, 2024
Description
Most of the property is open and covered in grasses. Trees exist mostly on the property perimeters. 48
trees that meet the size requirements for a significant tree were identified on the property. A significant
tree is any tree with a caliper of at least 6-inches or alder or cottonwood tree at least 8-inches. Trees
certified as high-risk shall not be considered significant.
Trees have been marked with a numbered aluminum tag, attached to the lower trunk. Tree numbers
correspond with the numbers on the attached Tree Summary Tables and map.
An additional 11 off-site trees were also assessed. These are located within a proximity of the east and west
property lines. There are also five trees within the right-of-way of SE 192nd Street.
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 or canopy of the tree is examined for current vigor/health by examining the foliage for
appropriate color and density, the vegetative buds for color and size, and the branches for structural
form and annual shoot growth; and the overall presence of limb dieback and/or any disease issues.
• The trunk or main stem of the tree is inspected for decay, which includes cavities, wounds, fruiting
bodies of decay (conks or mushrooms), seams, insect pests, bleeding or exudation of sap, callus
development, broken or dead tops, structural defects and unnatural leans. Structural defects can
include but are not limited to excessive or unnatural leans, crooks, forks with V-shaped crotches,
multiple attachments.
• The root collar and exposed surface roots are inspected for the presence of decay, insect damage, as
well as if they have been injured or wounded, undermined or exposed, or the original grade has
been altered.

Judging Condition
The three condition categories are described as follows:
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 to moderate 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 cause 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
The attached Tree Summary Table provides specific information on tree sizes and dripline measurements.
Observations
Most of the property is open and covered in grasses. Trees exist mostly on the property perimeters.
Noteworthy observations are discussed as follows.
14 of the subject trees are a grouping of native black cottonwood at the back of the property. Roughly
half of these have developed major leans and are highly susceptible to failure/stem breakage. See
pictures below. Eight are rated as ‘high’ risk.
Several trees were planted around the tower site and adjacent to its access drive on the east perimeter
of the property. They appear to have been planted for screening purposes. Species include
predominantly ‘Excelsa’ Western red cedar, a few Sitka spruce and a few Colorado blue spruce. These
are mostly in good condition. A few of the cedars have been damaged by drought stress in the past,
evident by some top decline/dieback. A few of the cedars along the access driveway have sunscald
damage, evident by cambium dieback on the lower trunks – west sides. This likely occurred when brush
was removed around the trees and lower trunks were exposed to the sun.
Some black cottonwood and red alder trees have naturally regenerated within the east perimeter
planting areas. Cottonwood Trees #27, #28 and #29 have overtopped the cedars and spruce are
somewhat suppressing them.
Off-site/Neighboring Trees
Trees #101 and #108 > #111 are located within the SE 192nd street right -of-way. #101 is a young
Western red cedar that was topped several of years ago at roughly 6-feet above ground. The intention
was probably to maintain it as a hedge but was left unmanaged and has developed multiple new tops to
a height of 24-feet. It is in fair condition. Tree #1 adjacent to it is in the same condition.

Updated December 2, 2024
Tree #110 is a mature European white birch. It is in poor condition, evident by dead and broken tops. It
is infected with the Bronze Birch Borer pest. It is in an ultimate state of decline. It is not viable.
Tree #111 is a young to semi-mature bigleaf maple in a grouping with property trees #46 and #47 that
are the same size and species. Vigor appears to be good. These are surrounded by a compacted gravel
driveway.
Tree #102 is a young Douglas fir in good condition with no concerning issues.
Tree #103 is a large, mature bigleaf maple. Some decay within the lower trunk and upper bole is visible
from the subject property. Overall condition is rated as ‘fair’.
Tree #104 is a mature native Scouler’s willow located close to the west property line. It appears to be of
good vigor for age. This is a short-lived species. There is moderate deadwood within the canopy.
Tree #105 is a semi-mature bigleaf maple located roughly 12-feet off of the west property line fence. No
concerning issues were observed from the subject property side. Condition is ‘good’.
Discussion/Recommendations
48 trees that meet the size requirements for a significant tree were identified on the property. A significant
tree is any tree with a caliper of at least 6-inches or alder or cottonwood tree at least 8-inches. Trees
certified as high-risk shall not be considered significant. Eight of the subject cottonwood trees are high risk
and therefore considered non-significant. Five of the subject trees are located within the proposed new
public street right-of-way. There are a total of 35 significant trees on the property.
The cottonwood trees are problematic. This is a very fast-growing and vigorous species. The species has
brittle wood structure and is prone to large branch and stem failures. Complete crown failure, and loss
of large lateral limbs is common, especially where the tree is dominant and subject to strong winds, or
wet snow1. Sudden limb drop is common at all times of year, often with no wind or other predisposing
factors in play. These are not good candidates for retention and not suitable within the striking distance
of high value targets. They will be an issue for the new homeowners in the near future. Removal and
replacement are recommended.
The proposal is to retain the trees #3, #7, #23 and #25. These are well-positioned for successful
retention in the corners of the property away from proposed disturbances. See the attached tree plan
map. Position the tree protection barrier/fencing around them as shown on the map. Unfortunately,
there is little opportunity to retain trees at this site. Trees best positioned for successful preservation at
the back of the property are all cottonwoods.
All of the trees within the SE 192nd Street right-of-way and those adjacent to it will need to be removed
for utility upgrades and street frontage improvements.

A realignment of the cell tower property access drive will require the removal of Trees #35 > #39. Since
these trees are within a required easement, they are not included in the tree retention calculations.
General Tree Protection Guidelines
Tree protection fencing shall be positioned around any retained and/or protected trees prior to site
demolition or bringing any heavy equipment onto the site. This will help to define clearing limits and
protect soils and surface roots.
Any roots damaged during site work outside of the tree protection fenced area shall be pruned clean at
sound tissue prior to backfilling or finishing areas. Sound tissue is where the root is undamaged and the
bark is completely intact with the root. This will help roots to seal off potential decay and allow them to
sprout new growth. Any disturbed areas near protected trees shall be watered weekly during the dry
season of June through September. This will help to create a favorable environment for new root
growth and reduce the overall stress associated with root loss and disturbance.
Simply finish the landscape within the driplines by maintaining the existing lawn or covering the ground
with a 3 to 4-layer of organic mulch. Maintain the existing grades inside tree protection areas. Keep
large plantings, irrigation trenching and construction of hardscapes outside of tree protection areas. All
landscape work within the tree protection zone shall be completed by hand-labor only.
General Tree Protection Measures
The following guidelines are recommended to ensure that the designated space set aside for the
retained trees is protected and construction impacts are kept to a minimum. Tree Protection Standards
have been set forth under RMC 4-4-130 H. Performance Standards for Land Development/Building
Permits; 9. Protection Measures During Construction. Review this code section prior to the start of
work.
• Tree protection fencing shall be erected per prior to moving any heavy equipment on site. Doing
this will set clearing limits and avoid compaction of soils within root zones of retained trees.
• Excavation limits shall be laid out in paint on the ground to avoid over excavating.
• 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.
• 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. Large equipment shall be kept outside of the tree protection zones at all times.

Tree Density-Tree Replacement
H. PERFORMANCE STANDARDS FOR LAND DEVELOPMENT PERMITS:
1. Protected Trees: Trees required to be retained or planted pursuant to this subsection H1 are
considered protected trees, as defined in RMC 4-11-200, Definitions T. Protected trees shall be retained
or planted as follows:
a. Minimum Tree Retention Requirements: Properties subject to an active land development permit
shall retain a minimum of thirty percent (30%) of all significant trees on site.
There are a total of 35 significant trees on the property. Five of these are within the proposed new
public road right-of-way, requiring the retention of 9 trees. The proposal is to retain 4 of the 30 existing
significant trees on the property, which equates to 13.3%.
b. Tree Credit Requirements: With the exception of interior remodels not involving any building
addition, removal of trees, or alteration of impervious areas, properties subject to an active land
development permit shall comply with all of the following minimum tree credit requirements, and apply
the tree credit value table in subsection H1bv of this Section:
i. Tree credit requirements shall apply at a minimum rate of thirty (30) credits per net acre.
ii. Either tree retention or a combination of tree retention and supplemental tree planting (with new
small, medium, or large tree species) shall be provided to meet or exceed the minimum tree credits
required for the site.
Because the proposal falls short of 30% retention of significant trees, many replacement tree credits will
be required. The landscape architect will determine the number of small, medium and large
replacement trees needed to satisfy city codes and to develop an appropriate tree replacement plan for
the project.

Arborist Disclosure Statement
Arborists are tree specialists who use their education, knowledge, training and experience to examine
and assess trees, recommend measures to enhance the beauty and health of trees, and attempt to
reduce the risks associated with living near trees. Clients may choose to accept or disregard the
recommendations of the arborist, or to seek additional advice.
Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees
are living organisms that grow, respond to their environment, mature, decline and sometimes fail in
ways we do not fully understand. Conditions are often hidden within trees and below ground.
Arborists cannot guarantee that a tree will be healthy and/or safe under all circumstances, or for a
specified period of time. Likewise, remedial treatments, like any medicine, cannot be guaranteed.
Treatment, pruning and removal of trees may involve considerations beyond the scope of the arborist’s
services such as property boundaries, property ownership, site lines, disputes between neighbors, and
other issues. Arborists cannot take such considerations into account unless complete and accurate
information is disclosed to the arborist. An arborist should then be expected to reasonably rely upon
the completeness and accuracy of the information provided.
Trees can be managed, but they cannot be controlled. To live near trees is to accept some degree of
risk. The only way to eliminate all risk associated with trees is to eliminate all trees
