PROJECT LOCATION: 204 Bremerton Ave SE, Renton, WA 98059 (APN 2525000080)
PROJECT DESCRIPTION: The applicant is requesting a Routine Vegetation Management Permit (RVMP) to
remove a Douglas fir (Pseudotsuga menziesii) located at 204 Bremerton Ave SE
(APN 2525000080). The subject property is approximately 7,500 square feet (0.17
acres) and is situated within the Residential-6 (R-6) zone and the Highlands
Community Planning Area. According to the City of Renton (COR) Maps, the
property has sensitive and protected slopes (>15% &<=90%) and a Type F stream
buffer (Maplewood Creek) on site. The tree proposed for removal is located within
the stream buffer and therefore it requires a Critical Areas Exemption.
An Arborist Report, prepared by Salish Sea Tree Care Consulting (Attachment A)
was submitted with the application. In the report, the ISA Certified Arborist,
Nicholas Johnson, proposed the removal of one (1) of the Douglas fir
(Pseudotsuga menziesii) trees, labeled Tree 4, that is thirty-five inches (35”) in
diameter at breast height (dbh). According to the report, the tree was previously
over-pruned and is now infested with Douglas fir beetles, which has caused
significant stress and has led to its current state of decline. Due to Tree 4 being
located close to the residence and immediately abutting the deck of the home,
the arborist recommends removing the tree. The arborist also notes ways to
mitigate the beetle activity to encourage growth of the other Douglas fir
(Pseudotsuga menziesii) trees on site, as well as non-removal hazard mitigation
measures.

CRITICAL AREA: Sensitive and protected slopes, (>15% & <=90%), and Type F stream buffer
(Maplewood Creek)
EXEMPTION JUSTIFICATION: Renton Municipal Code (RMC) 4-3-050 Critical Areas Regulations: RMC 4-3-
050C.3.c.iii, Dangerous Trees: Removal of non-native invasive ground cover or
weeds listed by King County Noxious Weed Board or other government agency or
dangerous trees, as defined in chapter 4-11 RMC, which have been approved by
the City and certified dangerous by a licensed landscape architect, or certified
arborist, selection of whom to be approved by the City based on the type of
information required. Limited to cutting of dangerous trees; such hazardous
trees shall be retained as large woody debris in critical areas and/or associated
buffers, where feasible.
RMC 4-3-050.C.3.c.iii EXEMPT, PROHIBITED AND NONCONFORMING
ACTIVITIES: Activities taking place in critical areas and their associated buffers
and listed in the "Exempt Activities – Permitted Within Critical Areas and
Associated Buffers" table are exempt from the applicable provisions of Section
4-3-050, provided this letter of exemption has been issued.
ROUTINE VEGETATION MANAGEMENT REVIEW CRITERIA 4-9-195D.4:
YES 1. The lot shall comply with minimum tree credit requirements pursuant to RMC 4-4-130,
Tree Retention and Land Clearing Regulations.
Staff Comments: In accordance with RMC 4-4-130H, compliance with tree credit
requirements necessitates a minimum of 30 tree credits per net acre. The subject
property is located at 204 Bremerton Ave SE (APN 2525000080) and is approximately
7,500 square feet (0.17 acres). Based on the property size, flve (5) tree credits are required
to meet the minimum tree density requirement (30 tree credits/acre × 0.17 acres = 5.1
credits).
According to the Tree Retention and Credit Worksheet (Attachment B), the applicant is
proposing to retain flve (5) trees on the property which total 33 tree credits. Therefore, the
preserved trees exceed the calculated flve (5) required tree credits for the property and
the Tree Retention and Credit Worksheet demonstrates compliance with the minimum
tree credits and the minimum retention requirements.
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: City of Renton (COR) Maps has identifled sensitive and protected
slopes (>15% & <=90%), as well as the buffer of a Type F stream (Maplewood Creek), on-
site. The tree proposed for removal is within the stream buffer; therefore, a Critical Areas
Exemption certiflcate is a component of this decision. Refer to the Critical Area
Exemption Findings below for additional exemption information.
YES 3. Removal of a landmark tree shall meet the review criteria for removal of a landmark tree,
pursuant to RMC 4-4-130, Tree Retention and Land Clearing Regulations.
Staff Comments: According to RMC 4-4-130.F.2.c.i, a landmark tree may be removed if
it is determined to be high risk. In RMC 4-11-200, a high-risk tree is classifled as such if it
has a probable or imminent likelihood of failure; and a medium or high likelihood of
impact; and the consequences of failure for the tree are signiflcant or severe.

Routine Vegetation Management Permit
LUA25-000162 RVMP, CAE
Permit Date: June 23, 2025 Page 3 of 6
In the Arborist Report (Attachment A), the certifled arborist describes the decline of Tree
4 to show how it has a probable likelihood of failure. The lower canopy of the tree was
previously removed, and the remaining canopy of the tree is abnormally thin with a heavy
cone crop- both indicators of high stress for the tree. In addition, the tree has extensive
Douglas flr beetle activity, as demonstrated in Figure 2 of the Arborist Report (Attachment
A), which further impacts the health of the tree. The arborist states the tree is in decline
and mitigation measures are unlikely to improve its health. Therefore, the tree has a
probable likelihood of failure.
The tree also could impact the residence on the property. Behind the house, the tree is
located less than one foot (1’) from the deck that has been altered to accommodate the
root fiare of Tree 4. Due to the apparent height of Tree 4, observable in Figure 3 of the
Arborist Report (Attachment A), the tree is within striking distance of the home on the
project site. If the tree were to fail and strike the home, potential consequences would be
severe. Due to this level of risk, Tree 4 is classifled as a high-risk tree and staff concurs
the tree should be removed due to meeting criterion i in RMC 4-4-130F2.c.
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 subject tree is not a street frontage tree nor a
parking lot tree. Neither street frontage nor parking landscape is proposed to be removed.
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 removal would not be removing landscaping
or protected trees required as part of a land development permit.
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 proposed for removal is located in the interior of the parcel
and thus, the proposed removal would not negatively impact visual screening or buffering
between nearby single-family residences, which are also zoned Residential- 6 (R-6).
YES, IF
CONDITIONS
ARE MET
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: The removal of the dangerous tree, as recommended by the arborist,
would not create a hazardous condition. Since there appears to be Douglas flr beetle
activity on the trees at this site, the arborist recommends annual monitoring by a qualifled
arborist for the Douglas flr trees labeled “Tree 2” and “Tree 3” in the Arborist Report
(Attachment A) for flve (5) years following the removal of “Tree 4.” The arborist also
advises installing MCH Bubble Capsules on the stems of Tree 2 and Tree 3 each year on
April 1st. Therefore, as a condition of approval, the applicant shall annually have Tree 2
and Tree 3 monitored by a qualifled arborist and install MCH Bubble Capsules on the
stems of Tree 2 and Tree 3 each year on April 1st for flve (5) years.
N/A 8. The land clearing and tree removal shall be consistent with the requirements of the
Shoreline Master Program, pursuant to RMC 4-3-090F1, Vegetation Conservation, and
RMC 4-4-130, Tree Retention and Land Clearing Regulations.

CRITICAL AREA EXEMPTION FINDINGS:
The proposed development is consistent with the following flndings pursuant to RMC 4-3-050C.2.d:
YES i. The activity is not prohibited by this or any other provision of the Renton Municipal Code
or State or Federal law or regulation.
Staff Comments: Removal of dangerous trees is not prohibited by any federal regulations
and it is an exempt activity in the City of Renton’s Critical Areas Regulations. Approval of
this exemption would act as written permission to allow the removal of the identifled tree.
YES, IF
CONDITIONS
ARE MET
ii. The activity will be conducted using best management practices as specifled by industry
standards or applicable Federal agencies or scientiflc principles.
Staff Comments: The best management practice recommended by the arborist in the
Arborist Report (Attachment A) is to remove Tree 4 because it is a hazardous tree. The
arborist also recommends multiple best management practices for the site to promote
growth of the existing trees and to mitigate any potential physical hazards. The arborist
recommends measures to dissuade Douglas flr beetle activity and regular monitoring of
Tree 2 and Tree 3, as noted as a condition in Section 7 of the report. The arborist also
recommends pruning Tree 5, a red maple (Acer rubrum) that is approximately thirty-three
inches (33”) in diameter at breast height (dbh), by utilizing branch removal and reduction
cuts to eliminate 15-20% of the foliage overhanging the roadway. In addition, the arborist
recommends applying one (1) reduction cut to each of the two (2) outer stems of Tree 6,
a western red cedar tree (Thuja plicata) that is approximately flfteen inches (15”) dbh,
which would remove four feet (4’) of height to reduce the likelihood of stem failure. The
central stem of Tree 6 would remain uncut. The arborist also recommends yearly
monitoring of Tree 6 by a qualifled arborist.
Staff concurs with the best management practices recommended by the arborist and
therefore staff recommends, as a condition of approval, the applicant shall prune Tree 5
by utilizing branch removal and reduction cuts to eliminate 15-20% of the foliage
overhanging the roadway. In addition, the applicant shall perform one (1) reduction cut
to each of the two (2) outer stems of Tree 6 and have an arborist monitor the tree annually.
YES iii. Impacts are minimized and, where applicable, disturbed areas are immediately restored.
Staff Comments: The removal of Tree 4 is aimed at minimizing the potential impacts of
tree failure, such as damage to the nearby home, while also improving the overall health
of the remaining trees on the property. This is accomplished through the measures
described in the above comment.
YES iv. Where water body or buffer disturbance has occurred in accordance with an exemption
during construction or other activities, revegetation with native vegetation shall be
required.
Staff Comments: The tree proposed for removal is located within a Type F stream buffer
for Maplewood Creek which requires revegetation. In this instance, revegetation would not
be beneflcial since there are already flve (5) other trees on the small site. As the property
currently stands, removal of Tree 4 would result in a net positive due to allowing the other
Douglas flr (Pseudotsuga menziesii) trees, that have been overshadowed by Tree 4, to grow
better. The spirit of this requirement is to provide a net positive to the area following a

removal and the spirit of that intent is met by removing Tree 4 and treating the trees for
beetle activity.
N/A v. If a hazardous material, activity, and/or facility that is exempt pursuant to this Section has
a signiflcant or substantial potential to degrade groundwater quality, then the
Administrator may require compliance with the Wellhead Protection Area requirements
of this Section otherwise relevant to that hazardous material, activity, and/or facility. Such
determinations will be based upon site and/or chemical-speciflc data.
Staff Comments: Not applicable. The proposal does not include a signiflcant or
substantial potential to degrade groundwater quality.

WHY A TREE INVENTORY AND CONDITION ASSESSMENT WAS CONDUCTED
You would like to remove one Dougals fir (Pseudotsuga menziesii) located near the back of your home at 204
Bremerton Avenue Southeast, Renton, WA. You were asked by the City of Renton to provide an inventory of
the trees onsite along with a project narrative.
On April 14th 2025 you retained Salish Sea Tree Care and Consulting to provide a report containing a Project
Narrative and a Tree Retention/Land Clearing (Tree Inventory) Plan consistent with RMC 4-9-195.
HOW DATA WAS COLLECTED AND ANALYZED
We visited the site on April 24th, 2025, to inventory the trees onsite and collect site data.
The tools used for the assessments were:
• A diameter tape
• A cellular phone
• Visual observation
• Notepad
The data collected consisted of:
• Genus and species
• Tree diameter
• Condition
• Description and Notes
Inventoried trees were assigned unique and sequential identification numbers one – seven for the purpose of
this report.
Tree Credits were determined by using the table shown in RMC4-4-130.H.1.b. Trees that straddle the property
boundary or were suspected of being offsite were not included in tree credit calculation.
Diameter of tree stems straddling a property boundary or that were suspected of being offsite were
estimated.
Diameter at Standard Height (DSH) of trees onsite were measured with a diameter tape at four and a half feet
above grade and rounded to the nearest half inch. For multi-stem trees, aggregate DSH was calculated using
the following formula: DSH = (√d12+ d22+ d32+ d42). Where d1, d2, etc., are each stem’s DSH value. The
resulting value was rounded to the nearest half inch.

Email: salishseatree@gmail.com
Tree condition was assessed using the criteria below:
• Excellent – High vigor and nearly perfect health with little or no twig defects or discoloration. Nearly ideal
and free of defects. Generally symmetric and consistent with intended use.
• Good – Vigor is normal for the species. No significant damage due to disease or pests. Only minor twig
defects or discoloration. Minor asymmetry from species norm. Function and aesthetics are not
compromised.
• Fair – Reduced vigor. Damage from insects or disease may be significant but is not likely to be fatal. Twig
defects, damage and discoloration may comprise fifty percent of the crown. A single defect of significant
nature or multiple moderate defects are present and not practical to correct or would require multiple
treatments to correct.
• Poor – Poor vigor. Unhealthy and declining appearance. Low foliage density and poor color. Potentially
fatal pests or diseases. Extensive defects, damage and discoloration of twigs. Singular or multiple structural
defects. Recent changes in tree orientation. Structural defects that cannot be corrected. A structural
failure is expected. Appearance is asymmetric or abnormal and detracts from the intended use or
aesthetics significantly.
• Very Poor – Vigor is poor. Appears to be dying. Singular or multiple severe defects. A structural failure is
probable or imminent. Visually unappealing provides little or no function in the landscape.
• Dead – Little to no indication of life.
TREE INVENTORY
Seven trees in total were inventoried and assessed. I suspect two of the trees are boundary trees or located
offsite. Tree 1, and Engelmann spruce (Picea engelmannii) may be outside of your property boundary. Tree 6,
a Western redcedar (Thuja plicata) appears to straddle your southern property boundary and may be a
boundary tree shared by two properties.
There were five trees identified as being within your property boundary, three Douglas fir, one red maple
(Acer rubrum) and one crab apple (Malus spp.)
One Douglas fir and the red maple are considered Landmark Trees, two Douglas fir are considered Significant
Trees, and the crab apple was considered to be a New Small Species Tree.

PROPOSED TREE REMOVAL
You would like to remove Tree 4, a Douglas fir that is considered a Landmark Tree. This tree is on or at the top
edge of a fifteen – twenty-five-degree slope. The stem of this tree is growing within inches of your deck which
has been altered to accommodate it’s root flair.
Prior to the purchase of your home, a significant portion of this tree’s lower canopy was removed. I estimate
the canopy loss from the pruning to be greater than fifty percent of the vegetative foliage.
The remaining canopy of the tree is abnormally thin, a sign of stress and often Douglas fir beetle
(Dendroctonus pseudotsugae) activity. Douglas fir beetle exit holes were observed on the main stem of the
tree and their galleries on a failed branch found near the base of the tree.
Figure 2. Douglas fir beetle activity observed on failed branch.
The excessive pruning has caused this tree a great deal of stress and it appears to be in an early state of decline
and attack by Douglas fir beetle. It is unclear if supportive treatments such as supplemental irrigation, fertilizer,
insecticides and pheromone deterrents would be effective in preserving the tree.

RECOMMENDATIONS
If Tree 4 is removed, it will increase light and wind exposure to Tree 2 and 3. I recommend annual monitoring
of these trees by a qualified arborist for a period of five years following the removal. I also recommend
annually installing MCH Bubble Capsules to the stems of your Douglas fir on April 1st to dissuade further
Douglas fir beetle activity onsite.
I recommend pruning Tree 5 with the objective of reducing the likelihood of stem failure from the poor stem
attachments at the base by utilizing branch removal and reduction cuts to remove fifteen – twenty percent of
the vegetative foliage located over the roadway.
I recommend applying one reduction cut to each of the outer two stems of Tree 6, removing four feet in height
with the objective of reducing the likelihood of stem failure. The central stem should be preserved and left
untouched. You may need to receive permission from your neighbor to the south to alter this tree in any way. I
also recommend annual monitoring of this tree by a qualified arborist.
I appreciate the opportunity to provide you with information about your trees. Please do not hesitate to let me
know if you have any questions or if we can be of further assistance.

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.
