EVALUATION FORM & DECISION
DATE OF DECISION: September 19, 2023
PROJECT NUMBER: LUA23-000293, RVMP
PROJECT NAME: Duval RVMP
PROJECT MANAGER: Mariah Kerrihard, Assistant Planner
APPLICANT: Christine Leonard
5101 S 372nd St Auburn, WA 98001
OWNER: Dennis Duval
411 S 19th St
CONTACT: Christine Leonard
5101 S 372nd St Auburn, WA 98001
PROJECT LOCATION: 411 S 19th St Renton, WA 98055
PROJECT DESCRIPTION: The applicant is requesting approval of a Routine Vegetation Management Permit
(RVMP) to allow the removal of four (4) landmark trees and one (1) significant tree. These trees include: a 25-inch
(25”) DBH Lombardy Poplar (Populus nigra), a 27-inch (27”) DBH Lombardy Poplar, a 34-inch (34”) DBH Lombardy
Poplar, a 38-inch (38”) DBH Lombardy Poplar, and a 12-inch (12”) DBH Lombardy Poplar. The subject property
currently contains 16 landmark trees and one (1) significant tree in which all are Lombardy Poplars (Populus nigra).
The applicant submitted an arborist report, prepared by Ryan Seeley of Pacific Arboriculture, an ISA Certified
Arborist (Attachment 1). The applicant provided a full tree survey of the site as part of the arborist report. This
arborist report describes risk posed to a neighboring residence by the trees on the property. According to Seeley,
the risk rating is “HIGH” because of significant die-back, dead tops, sparse canopy and three (3) of the five (5) trees
are dead. This property is located at 411 S 19th Renton, WA 98055. The lot size of the property is .26 net acres
(11,250 square feet). This lot size would require Dennis Duval to have 8 retention credits. After the removal of the
five (5) trees, the applicant will have a total of 143 retention credits. The other trees were also assessed at various
levels of health and were recommended to retain and monitor.
The Routine Vegetation Management Permit is required for the removal of three (3) or more significant trees
within a one-year period where tree cutting is not associated with a land development permit. A Routine
Vegetation Management Permit is also required for the removal of any landmark tree.
CRITICAL AREA: None
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: The tree being removed is within the Parcel ID:7222000362. The lot size
of the property 411 S 19th St is .26 net acres which would require the applicant to have eight
(8) retention credits (30 tree credits per acre x .26 acres = 7.8). With the removal of the five
(5) trees there will be a total of 143 tree retention credits on the property based on the
remaining 12 trees identified in the arborist report (Attachment 1).
YES 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: The COR mapping system has identified a potential moderate coal mine
hazard on a portion of the subject property. The removal of the dead and diseased poplars
is not anticipated to create a hazardous condition and the removal is consistent with the
restrictions for critical areas.
YES 3. Removal of a landmark tree shall meet the review criteria for removal off 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: The applicant is requesting to remove four (4) landmark trees and one
(1) significant tree. All five (5) trees are Lombardy Poplar ranging in diameter from 12-
inches (12”) to 38-inches (38”). Of these five (5) trees, they were all identified as dead or
being high-risk trees, thereby meeting criterion #1. The trees are showing significant
sapwood decay and root rot.
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 project trees are not 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 trees were 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 property is located within the R-8 zone. The northern property line
abuts the right-of-way for S 19th St, a minor arterial. The surrounding parcels along the
property lines are within the R-8 zone. Removal of the trees 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 trees
would create or contribute to a hazardous condition, but instead indicated that it is a net
benefit that the trees have been removed. Lombardy Poplars generally have short life
spans. They come from the Mediterranean region and are adapted to hot, dry summers
and grow poorly in humid conditions, making them short lived due to fungal diseases. They
are not good landscape trees because they are susceptible to several pest and diseases.
Further, they are not appropriate in the urban environment as their roots are very invasive
and shallow which can lift sidewalks, make lawn mowing difficult and damage drainage
and other subsurface utility systems.
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.
DECISION: The Duval RVMP, LUA23-000293, RVMP, for the removal of five (5) significant trees as shown in the
arborist report (Attachment 1) is Approved .

Findings and Recommendations
Introduction
As requested by Dennis Duval, I visited the property on March 14, 2023. I provided an
assessment of the trees located at 411 S 19th St Renton, WA 98055 to discuss plans for removing
several Lombardy Poplars, Populus nigra, on the property that have been a nuisance and cause of
concern for Mr. Duval and his neighbors due to several being dead and constant shedding of
material on surrounding properties.
Summary
I was contacted by Dennis Duval to report the measurements, health, and condition of
several trees on the property that have been a constant concern and plans to renovate his yard to
benefit the community.
Findings and Recommendations
On the property of 411 S 19th St Renton, WA 98055 there are 16 Landmark trees and 1
Significant tree. Mr. Duval is requesting to remove 4 Landmark trees and 1 Significant tree, all
Lombardy Poplars, Populus nigra, that have been a constant cause of concern for Mr. Duval and
his neighbors. The size, health, and planned course of action for each tree within the area of
proposed demolition is explained in further detail on the Tree Inventory Matrix located on page 7.
In my professional opinion after my meeting with Mr. Duval and speaking with his
neighbors while observing the current conditions of the trees being requested for removal, I believe
removing the 5 poplars would add value to Mr. Duvals’s property and benefit the community as a
whole.

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.
Codominant 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: E3295A41-B00B-46BC-B715-3DCB8BB5E9B3
13
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.
Urban Forestry: Management of naturally occurring and planted trees in urban areas.
DocuSign Envelope ID: E3295A41-B00B-46BC-B715-3DCB8BB5E9B3
14
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
number 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.
Thank you for allowing me to be of service. Please contact me with any questions or concerns.
