EVALUATION FORM & DECISION
DATE OF DECISION: January 30, 2024
PROJECT NUMBER: LUA24-000033, RVMP
PROJECT NAME: Senait RVMP
PROJECT MANAGER: Mariah Kerrihard, Assistant Planner
APPLICANT: Senait Beyene
17218 130th Ave SE Renton, WA 98058
OWNER: Same as Applicant
CONTACT: Same as Applicant
PROJECT LOCATION: 17218 130th Ave SE (APN 7229210090)
PROJECT DESCRIPTION: The applicant is seeking approval for a Routine Vegetation Management Permit
(RVMP) for the removal of a single landmark tree, a 49-inch (49”) DBH Douglas Fir (Pseudotsuga menziesii), on the
property located at 17218 130th Ave SE, Renton, WA. The lot size of the property is 0.18 acres (8,010 square feet),
necessitating the applicant to maintain a minimum of six (6) tree credits. The arborist's assessment revealed that
the roots of the Douglas Fir are damaging utilities, leaving no viable alternative for maintenance. Public records
from Soos Creek public record officer Shari Snelling, along with insights from Artisan Plumbing & Mechanical,
highlighted the extensive damage caused by the tree roots, dislodging meter boxes, and breaking the water line
from the meter to the home. To address this, the arborist recommends excavating the Critical Root Area for utility
repairs. The certified arborist's written report, attached as Attachment 2, clearly establishes the Douglas Fir's role
in causing significant physical damage, meeting the criteria for removal. This damage extends to both utilities and
the driveway, posing risks to two nearby homes listed as targets. Presently, the property features one (1) landmark
tree. The arborist, recognizing the high risk, recommends removal following attempted utility maintenance
options. After a site visit on January 29, 2024, where staff visually inspected the tree, the determination of obvious
physical damage aligns with the arborist's findings. Consequently, staff recommends approving the removal of the
landmark tree. Upon the removal of the 13 credit landmark tree, the remaining tree credits on the property will
amount to zero (0) tree credits. The removal of this landmark tree will require six (6) replacement tree cred its,
which can include six (6) new medium species trees or three (3) large new species trees. The applicant, supported
by an arborist report from ISA Certified Arborist Ryan Seeley, conducted a comprehensive tree survey describing
the physical damage that has occurred to the utilities and the two neighboring homes.

EXPIRATION DATE: One (1) year from issuance
GENERAL REVIEW CRITERIA 4-9-195D4:
YES 1. The lot shall comply with minimum tree density requirements pursuant to RMC 4-4-130,
Tree Retention and Land Clearing Regulations.
Staff Comments: In accordance with RMC 4-4-130.H, tree credit requirements must meet a
minimum rate of 30 credits per net acre. The applicant provided a tree credit calculation
within the arborist report (refer to Attachment 2), indicating that the site initially held a
total of 13 tree credits. Following the removal of one (1) tree, resulting in a loss of 13 credits,
the site would then possess a total of 0 tree credits. Considering the site's total area,
approximately 0.18 net acres, and applying the rate of 30 credits per acre (30 credits x 0.18
acres = 6 credits), the site would need to replace six (6) tree credits to comply with the tree
credit requirement. This compliance is contingent on the removal of the one (1) Douglas Fir
tree (Pseudotsuga menziesii). To ensure compliance with the City’s minimum tree density
requirement and as the tree to be removed is a healthy native landmark large species tree,
staff recommends the applicant replant three (3) native large species trees, unless
otherwise determined by the Current Planning Project Manager, for a total of six (6) tree
credits on the subject property in an area that will not conflict utilities or other
improvements as the trees mature. The trees shall be planted and inspected by City staff no
later than September 30, 2024, unless otherwise determined by the Current Planning Project
Manager.
N/A 2. The land clearing and tree removal shall be consistent with restrictions for critical areas,
pursuant to RMC 4-4-130, Tree Retention and Land Clearing Regulations, and RMC 4-3-
050, Critical Areas Regulations.
Staff Comments: Not applicable. The subject lot is not mapped with applicable critical
areas.
YES 3. Removal of a landmark tree shall meet the review criteria for removal off a landmark tree,
pursuant to RMC 4-4-130, Tree Retention and Land Clearing Regulations.
I. The tree is determined to be a high-risk tree; or
II. The tree is causing obvious physical damage to buildings (over 200 square feet),
driveways, parking lots, or utilities, and it can be demonstrated to the
Administrator’s satisfaction that no reasonable alternative to tree removal exist,
including tree root pruning, tree root barriers, tree cabling, or preventative
maintenance, such as cleaning leaf debris, deadwood removal, or
directional/clearance pruning; or
III. Removal of tree(s) to provide solar access to buildings incorporating active solar
devices. Windows are solar devices only when they are south facing and include
special storage elements to distribute heat energy; or
IV. The Administrator determines the removal is necessary to achieve a specific and
articulable purpose or goal of this Title.
Staff Comments: Criterion ii has been met. The applicant is requesting the removal of one
(1) landmark tree—a 49-inch (49”) DBH Douglas Fir (Pseudotsuga menziesii). A Routine
Vegetation Management Permit is mandatory for the removal of any landmark tree, not
associated with a land development permit. According to the arborist, the roots are
damaging utilities, and there are no alternative maintenance options. Soos Creek public
record officer Shari Snelling provided public records of work orders and correspondence

regarding the water leak at the abutting property, and a plumber from Artisan Plumbing
& Mechanical provided information on the underground tree roots that have dislodged the
meter boxes, surrounded the meter, and water line to the point of breaking the line from
the meter to the home. Due to the damage to the water line from the roots of the Douglas
Fir, the arborist recommends excavating the Critical Root Area to replace the water line
and stop the leak for the utilities' use. The roots of the tree are causing obvious physical
damage to the utilities. A certified arborist's written report (refer to Attachment 2)
identified this Douglas Fir as causing obvious physical damage, meeting the criteria for
tree removal. This specific tree has resulted in obvious physical damage to both the utilities
and the driveway, with two (2) homes listed as targets. Presently, the property features
one (1) landmark tree. The arborist who assessed the tree identified it as posing a high risk
due to excavation and maintenance work needed to repair the utility within the tree’s
critical root zone and recommends its removal following attempted utility maintenance
options. Staff visited the site on January 29, 2024, and visually inspected the tree.
Therefore, staff concurs with the determination of obvious physical damage and
recommends approval for the removal of the landmark tree.
N/A 4. Street frontage and parking lot trees and landscaping shall be preserved unless otherwise
approved by the Administrator.
Staff Comments: Not Applicable. The tree is not a part of street frontage, parking lot or
landscaping trees.
N/A 5. The land clearing and tree removal shall not remove any landscaping or protected trees
required as part of a land development permit.
Staff Comments: Not Applicable. The tree was not required as part of a land development
permit for landscaping or tree requirements. Neither street frontage nor parking
landscaping is proposed to be removed.
YES 6. The land clearing and tree removal shall maintain visual screening and buffering between
land uses of differing intensity, consistent with applicable landscaping and setback
provisions.
Staff Comments: The tree is adjacent to a lot with a detached dwelling and is a use of
equal intensity. Removal of the tree would not remove required visual screening and
buffering between land uses of differing intensity.
YES 7. The land clearing and tree removal shall not create or contribute to a hazardous condition,
such as increased potential for blowdown, pest infestation, disease, or other problems that
may result from selectively removing trees and other vegetation from a lot.
Staff Comments: Provided documentation did not indicate that the removal of the tree
would create or contribute to a hazardous condition.
N/A 8. The land clearing and tree removal shall be consistent with the requirement of the
Shoreline Master Program, pursuant to RMC 4-3-090F1, Vegetation Conservation and
RMC 4-4-130, Tree Retention and Land Clearing Regulations.
Staff Comments: Not applicable. The property is not located within shoreline jurisdiction.

Introduction
As requested by Dynaa Depasquale, I visited the neighboring property of 17218 130th
Ave SE Renton, WA 98058 on January 25, 2024, with permission from the property owner
Senait Beyene, to report the measurements, health, and condition of a Douglas Fir, Pseudotsuga
menziesii, on the property that she wishes to remove due to disruptions to underground utilities
located directly under the tree.
Summary
I provided an assessment of the Douglas Fir, Pseudotsuga menziesii, located on the
property that has damaged their waterlines and disrupted services, they are also worried about
the future of their other underground utilizes and further damage to their driveway. Mrs.
Depasquale’s water line was damaged from the roots and needs to be excavated within the
Critical Root Area to replace the line and stop the leak so they may receive essential utilities.
Soos Creek Water & Billing stated in an email to Mrs. Depasquale, “We verified there
was a leak occurring at the property from 10/12/23 to present, based off the results at the meter.
You and I discussed that it was more than likely the tree roots of the neighbor’s tree, as it had
been a point of contention between your father and them and the worry of it causing issues in
your line. You were able to get a plumber out there who confirmed the leak was being cause by
the tree roots impacting the line. The pictures our crew were able to take of the tree indicates
how close it is to your line, and the neighbor’s line. I was told by our crew that it will start
DocuSign Envelope ID: 2C394091-482D-4261-9943-2B20E38727A8

impacting the neighbor’s line soon, along with Soos Creek’s lines on our side of the meter if left
unattended.”
Artisan Plumbing & Mechanical, LLC. also confirmed in a note, “Plumber arrived to
investigate a leak. He found that a fir tree has grown large enough underground that the roots
have dislodging meter boxes, surrounded the meter and water line to the point that they have
broken the line from meter to the home. There is no way to re-route the line or repair the line
without damaging the roots and compromising the integrity of the tree overall.” As shown in
Figure 4 on page 6.
The Douglas Fir, Pseudotsuga menziesii, needs to be removed from the property for the
water line to be repaired and prevent further damage to the remaining underground utilities.
Findings and Recommendations
The Douglas Fir, Pseudotsuga menziesii, referred to in this report has caused damage to
the underground water line and must be removed for excavation to repair the damaged pipes.
In my professional opinion, the Douglas Fir, Pseudotsuga menziesii, should be removed
to make excavation of major roots within the Critical Root Zone possible.

Retention Calculations
In accordance with Renton code Section 4-4-130 regarding PERFORMANCE
STANDARDS FOR LAND DEVELOPMENT PERMITS, With the lot size of the property of
17218 130th Ave SE Renton, WA 98058 at .18 net acres (8010 Sqft) would require property to
have 6 retention credits and not remove more than 30% of significant trees.
Given the circumstances 30% of trees cannot be retained therefore with the removal of
the only landmark tree on the property that would require the property to be responsible for
making up for a total 13 credits.

Glossary
Arborist: A person possessing the technical competence through experience and related
training to provide for or supervise the management of trees or other woody plants in a landscape
setting.
Basic Level 2 Risk Assessment: A detailed visual inspection of a tree and its
surrounding site and a synthesis of the information collected.
Canopy/crown: Upper part of a tree bearing foliage, limbs, and branches, measured from
the lowest branch including all branches and foliage.
Co-dominant Stem: A structurally unstable branch union often associated with a high
risk of failure. A term used to describe two or more main stems (or "leaders") that are about the
same diameter and emerge from the same location on the main trunk.
Crown Cleaning: In pruning, the selective removal of dead, dying, diseased and broken
branches from the tree crown.
Diameter at Breast Height: A standard measurement of a tree most often taken at 4.5
feet from the base of the tree; however, this can vary depending if the tree has multiple trunks or
is growing on a slope.
Hazard Tree: A tree that meets all the following criteria:
a. Has a combination of structural defects and/or disease which makes it subject to a high
probability of failure;
b. Is in proximity to moderate to high frequency targets (persons or property that can be
damaged by tree failure); and
c. The hazard condition of the tree cannot be lessened with reasonable and proper
arboricultural practices nor can the target be removed.
Live Crown Ratio: The ratio of the size of a tree's live crown to its total height. Used in
estimating a tree’s health and its level of competition with neighboring trees.
Mechanical Damage: Trees are often wounded by careless use of yard equipment like
mowers, weed whackers, and other trimming equipment. These injuries cut through important
vascular tissue just inside the bark that can lead to decay and ultimately death of the tree. A ring
of natural mulch or arborist wood chips around the tree eliminates the need to trim or mow close
to the tree's base. Extreme care should be taken when digging up or tilling the soil under a tree.
Many large and small roots will be cut by such digging, especially if it occurs close to the trunk.
DocuSign Envelope ID: 2C394091-482D-4261-9943-2B20E38727A8
10
Monitor: It is important to monitor mature trees on a regular schedule, at least once a year.
Monitoring would include a Visual Tree Assessment to look for changes in habit and structure,
and to document signs of weakness or decline in health and integrity of the trees.
Options for Mitigation of Risk Trees:
• Remove the risk altogether, if possible, by cutting off one or more branches, removing
dead wood, or possibly removing the entire tree. Extreme risk situations should be closed
off until the risk is abated.
• Modify the risk of failure probability. In some cases, it may be possible to reduce the
probability of failure by adding mechanical support in the form of cables braces or props.
• Modify the risk rating by moving the target. Risk ratings can sometimes be lowered by
moving the target so that there is a much lower probability of the defective part striking
anything. Moving the target should generally be seen as an interim measure.
• Retain and monitor. This approach is used where some defects have been noted but they
are not yet serious and the present risk level is only moderate.
• Convert those trees slated for removal into Wildlife Habitat Snags. Reduce the overall
height of the tree using natural fracture pruning techniques to heights relative to the
targets.
Pruning: Selective removal of woody plant parts of any size, using saws, pruners,
clippers, or other pruning tools. The reason for tree pruning may include, but is not limited to,
reducing risk, managing tree health and structure and/or improving aesthetics or achieving other
specific objectives. Pruning objectives should include pruning out all dead, diseased, weak
and/or broken branches in all tree canopies, and crown cleaning.
Snag or Habitat Snag: A standing, dead or dying tree, often missing a top or most of the
smaller branches important for wildlife in both natural and landscaped settings, occurring as a
result of disease, lightning, fire, animal damage, too much shade, drought, root competition, or
old age. May also be a component in slope stability and ongoing vegetation management
practices.
Threshold for Risk: Each individual is entitled to and can determine his or the own
threshold for risk. Threshold for risk is subjective, and can be influenced by a person’s view,
taste or opinion.
Topping: Topping is the indiscriminate cutting of tree branches to stubs or to lateral
branches that are not large enough to assume the terminal role. Other names for topping include
“heading,” “tipping,” “hat-racking,” and “rounding over.” Topping is not a viable method of
height reduction and does not reduce future risk. In fact, topping will increase risk in the long
term. Topping is not considered an acceptable arboriculture practice.

11
Urban Forestry: Management of naturally occurring and planted trees in urban areas.
Vigor: Overall health; the capacity to grow and resist physiological stress.
• Good: Shoot growth, leaf size and leaf color are typical of the tree age and species.
• Fair: Shoot growth, leaf size, and leaf color are below average for the tree age and
species. Some deadwood is evident in the crown. Treatment may be required to foster
improved future growth.
• Poor: Shoot growth, leaf size, and leaf color are highly stunted, and there is a significant
amount of dead twigs and branches in the crown.

Waiver of Liability
There are many conditions affecting a tree’s health and stability which may be present but
cannot be ascertained such as root rot, previous or unexposed construction damage, internal cracks,
stem rot and more. Changes in circumstances and conditions can also cause a rapid deterioration of a
tree’s health and stability. Adverse weather conditions can dramatically affect the health and safety
of a tree in a very short amount of time. While I have used every reasonable means to examine this
plant, this evaluation represents my opinion of the tree health at this point in time. These findings do
not guarantee future safety nor are they predictions of future events.
The tree evaluation consists of an external visual inspection of an individual tree’s root flare,
trunk, and canopy from the ground only, unless otherwise specified. The inspection may also consist
of taking trunk or root soundings for sound comparisons to aid the evaluator in determining the
possible extent of decay within a tree. Soundings are only an aid to the evaluation process and do not
replace the use of other more sophisticated diagnostic tools for determining the extent of decay
within a tree.
As conditions change, it is the responsibility of the property owners to schedule additional
site visits by the ISA Certified Arborist. It is the responsibility of the property owner to obtain all
required permits from city, county, state, or federal agencies. It is the responsibility of the property
owner to comply with all applicable laws, regulations, and permit conditions. If there is a
homeowner’s association, it is the responsibility of the property owner to comply with all Codes,
Covenants, and Restrictions (CC&R’s) that apply to tree pruning and tree removal.
This tree evaluation is to be used to inform and guide the client in the management of their
trees. This in no way implies that the evaluator is responsible for performing recommended actions
or using other methods or tools to further determine the extent of internal tree problems without
written authorization from the client. Furthermore, the evaluator in no way holds that the opinions
and recommendations are the only actions required to ensure that the tree will not fail. A second
opinion is recommended. The client shall hold the evaluator harmless for any and all injuries or
damages incurred if the evaluator’s recommendations are not followed or for acts of nature beyond
the evaluator’s reasonable expectations, such as severe winds, excessive rains, heavy snow loads, etc.
This report and all attachments, enclosures, and references are confidential and are for the
use of the client concerned. They may not be reproduced, used in any way, or disseminated in any
form without the prior consent of the client concerned and ISA Certified Arborist Ryan Seeley.

TREE RETENTION AND CREDIT WORKSHEET
TREE REPLACEMENT JUSTIFICATION
Replacement may be authorized as an alternative to 30% retention provided the removal is the minimum necessary to
accomplish the desired purpose and provided the proposal meets one of the following options:
a. There are special circumstances related to the size, shape, topography, location, or surroundings of the subject
property; or
b. The strict application of the code would prevent reasonable use of property; or
c. The strict application of the code would prevent compliance with minimum density requirements of the zone; or
d. The project is a short plat with four (4) or fewer lots.
Please attach a written justification demonstrating compliance with the requirements and criteria as descripted above.
TREE REPLACEMENT QUANTITY
Tree replacement quantity is determined based on the credit value of the trees proposed for removal. Larger, higher
priority trees shall be used for calculation of tree replacement. Identify the quantity of each tree requested to be removed
in lieu of 30% retention, based on tree size. List the identification number of each tree, as indicated in the arborist report.

Service Call - Investigation 0.0 $0.00 $0.00
Plumber arrived to investigate a leak. He found that a fir tree has grown large enough underground that the roots have
dislodging meter boxes, surrounded the meter and water line to the point that they have broken the line from meter to
the home. There is no way to re route the line or repair the line without damaging the roots and compromising the
integrity of the tree overall.
