RE: Hazard Tree Removal (PLN2024-0069)
720 Spruce St, Edmonds WA
Thank you for applying for a hazard tree removal at 720 Spruce St. Shellabarger Creek, a type of
environmentally critical area pursuant to the Edmonds Community Development Code (ECDC)
23.40, runs through the property. The removal of trees or vegetation within a critical area or critical
area buffer is not an allowed activity unless it involves the removal of invasive species or hazard
trees pursuant to ECDC 23.40.220.C.8.
Per the submitted arborist report and TRAQ form, the Red Maple tree meets hazard criteria.
Removal of 1 Red Maple tree, as recommended by your arborist, has been approved per ECDC
23.40.220(C)(8) with the following conditions:
1. This review only applies to the Red Maple tree identified in the photos and materials.
2. A minimum of two replacement trees must be planted in the general vicinity of the Red
Maple removed (location shown on site plan and as described in arborist report is sufficient).
Replacement trees must be species that are native and a minimum of one to two inches in
diameter at breast height (dbh) for deciduous trees and a minimum of six feet in height for
evergreen trees as measured from the top of the root ball.
3. The replacement trees must be installed within one year of the removal of the Red Maple.
Please provide photos of each of the planted replacement trees to verify installation and let
us know when to schedule a follow-up inspection.
If you have any questions, please let me know at either carmen.smith@edmondswa.gov or 425-771-
0220 ext. 1278.

Hello, my name is Walter Thompson. We live at 720 Spruce Street here in Edmonds. We have
lived at this address since 1975. Today I am applying for a permit to remove a 30 year old Red
Maple tree on this property. For the last several years I have noticed a sharp decline in the
tree's vigor and health. Lots of dead material and not many leaves. The tree is located in a
close proximity to our house as well being just several feet from a small creek that runs through
our property. One of many branches of Shelleberger Creek. I have contacted an arborist to do
a tree risk assessment on this tree. This report and her observations and site drawing are
included with this application. I will be replacing with one vine maples (acer circinatum) and
the other a larch approximately 5 ft in height on the NE side of the property. Thank you for your
kind consideration.

Dear Mr. Thompson:
Thank you for asking me to provide a memo stating my observations of one tree growing on
your property in Edmonds, Washington. To evaluate the tree addressed in this letter I combined
my field experience and education with current accepted practices as defined by the American
National Standards Institute (ANSI) and the International Society of Arboriculture (ISA).
The tools I used to make this assessment were limited to binoculars, diameter tape, compass and
laser pointer. A visual tree assessment and other methods are only conclusive for the day of
inspection and do not guarantee that conditions will remain the same in the future.
I was asked by Mr. Thompson to provide a brief memo with my observations of one tree growing
on his property in Edmonds, Washington. I completed a Level 2 tree assessment on August 8,
2024. All levels of assessment are explained in an attachment to this report.
The tree I assessed was one red maple (Acer rubrum). Its location is noted on the Man attached
to this report.
Red maple: — 12" DBH, stands two feet from a deck, four feet away from the home and three
feet away from a pond (Photos 1-2). It leans towards the home, over the deck and is within
range of numerous very good condition ornamental trees and shrubs.
There is a mature Ganoderma sp. conk present at the base of the tree. Near the conk on the trunk
is a larger area of sap flow indicating infection by the fungi (Photo 3). This fungi is fast acting in
this tree species and is considered to cause extensive base of the trunk rot within a few years
causing tree death or the probability of the tree falling over from the base of the trunk.

The foliage of the tree is dying. Leaves are very small and falling off. The tree is nearly dead.
At this point there is no way to improve the vigor or condition of the tree.
Tree risk assessment is a qualification that can be obtained through the ISA (International
Society of Arboriculture). The TRAQ (Tree Risk Assessment Qualification) methodology has
improved risk assessment by teaching assessors to follow a consistent format when examining a
tree.
Additionally, the TRAQ protocol includes defined terms for tree risk. The four terms under the
risk category Likelihood of Failure are Imminent, Probable, Possible and Improbable. Imminent
as defined in the TRAQ manual is an infrequent observance that would involve immediate risk
mitigation to prevent damage to a nearby target. The majority of trees I and other tree risk
assessors observe usually fall into the middle categories of Possible or Probable Likelihood of
Failure. Very rarely is a tree rated "Imminent" observed.
To assist in visualizing how a tree risk assessor determines risk, the following matrix used as part
of the protocols can be referred to below:

Keeping this risk rating system in mind during my assessment I found:
• There is a probable likelihood of failure from the base of the tree trunk (whole tree) with
a high likelihood of impact to multiple targets. Consequences of failure would be
significant, especially if the tree failed into the pond area. This tree is rated as a high risk
tree.

The time frame for this assessment is six months.
These trees stand close to a stream (see Critical Area Map). According to Edmonds Municipal
Code, if a certified arborist determines that a tree is hazardous, poses a threat to public safety, or
is an imminent risk of damage to private property, a permit for removal is not required but
documentation such as this report is needed.
Title 23 Natural Resources
Ch. 23.40.220.C.b Environmentally critical areas general provisions
i. The applicant submits a report from an ISA- or ASCA-certified arborist or registered
landscape architect that documents the hazard and provides a replanting schedule
for the replacement trees; (This report suffices for this requirement.)
ii. Tree cutting shall be limited to pruning and crown thinning, unless otherwise justified
by a qualified professional. Where pruning or crown thinning is not sufficient to
address the hazard, trees should be removed or converted to wildlife snags; (It is
not advisable to leave a traditional snag (over ten feet tall) standing due to the
proximity of the tree and then dying trunk to the home. Leaving a short trunk is
ok (below six feet tall).
iii. All vegetation cut (tree stems, branches, etc.) shall be left within the critical area or
buffer unless removal is warranted due to the potential for disease or pest
transmittal to other healthy vegetation or unless removal is warranted to improve
slope stability; (I strongly recommend AGAINST leaving any vegetation in the
critical areas or otherwise on the property due to extremely limited space being
available for laying anything other than one or two small logs. Wood chips
generated from chipping up any tree parts can be used in the landscape if desired
without risk of spreading disease.)
iv. The land owner shall replace any trees that are removed with new trees at a ratio of two
replacement trees for each tree removed (2:1) within one year in accordance with
an approved restoration plan. Replacement trees may be planted at a different,
nearby location if it can be determined that planting in the same location would
create a new hazard or potentially damage the critical area. Replacement trees
shall be species that are native and indigenous to the site and a minimum of one
to two inches in diameter at breast height (dbh) for deciduous trees and a
minimum of six feet in height for evergreen trees as measured from the top of the
root ball; ... in this case, there are VERY limited areas to replant this already
densely planted property. Small trees could be accepted on the northeast corner
of the property or as understory to the birch trees on the north portion of the

property as noted on the Man. Only very small or dwarf trees can fit in either of
these areas. Replacement trees shall not include any native tree species as there is
no room on this site for their young let alone mature growth sizes.
Tree species such as dwarf conifers, crepe myrtles, paperbark maples or fringe trees are
understory plantings that could work on this site.
Planting in the fall months and providing supplemental water for plants for up to one year
will help new trees establish. Use mulch or compost to surround the base of new
plantings to keep roots cool and moist through summer months.
How to submit for a permit: Use the My BuildingPwebsite (do not email application
materials to staff). The correct form is found under "Clearing and Grading"/ "Single Family"/
"Hazard Tree Removal". Also submit the TRAQ forms for this tree that are NOT attached to
this report but will come via email.
If you haven't used MBP before or need assistance with material submission, Development
Services/Planning can assist you (425) 771-0220. Once materials are submitted to mbp.com, the
request will show up in the queue for review.
Thank you very much for calling me for your arboricultural concerns.

Levels of Tree Assessment
LEVEL 1: The Level 1 assessment is a visual assessment from a specified perspective of an individual
tree or a population of trees near specified targets to identify obvious defects or specified conditions. A
limited visual assessment typically focuses on identifying trees with an imminent and/or probable
likelihood of failure.
Limited visual assessments are the fastest but least thorough means of assessment and are intended
primarily for large populations of trees.
LEVEL 2: This is a basic assessment completing a detailed visual inspection of a tree and surrounding
site, and a synthesis of the information collected. This assessment requires that a tree risk assessor walk
completely around the tree —looking at the site, buttress roots, trunk, and branches.
A basic assessment may include the use of simple tools to gain additional information about the tree or
defects. Basic is the standard assessment that is performed by arborists in response to a client's request
for tree risk assessment. Simple tools may be used for measuring the tree and acquiring more information
about the tree or defects. However, the use of these tools is not mandatory unless specified in the Scope of
Work.
LEVEL 3: Advanced assessments are performed to provide detailed information about specific tree
parts, defects, targets, or site conditions. They are usually conducted in conjunction with or after a basic
assessment if the tree risk assessor needs additional information and the client approves the additional
service. Specialized equipment, data collection and analysis, and/or expertise are usually required for
advanced assessments. These assessments are therefore generally more time intensive and more
expensive.
