Subject: GEOTF,CnNICAL EVALUATION OF A STEEP SLOPE CRITICAL AREA
Proposed Deck Resurfacing
Gordon -Goodman Residence
Edmonds, Washington
Dear Ms. Gordon -Goodman;
As requested, iiWA GcoScienes Inc. (IiWA) has undertaken a limited and cursory geotechnical
evaluation of your residence at 18420 Olympic View Drive in Edmonds, Washington.
We understand that you desire to re -surface your existing deck with a thermoplastic composite
product manufactured by AZEK Decking, and you desire to replace the existing handrails around
your deck. You indicated that the deck substructure would remain un-altered. The existing deck
surface is painted wood decking. The majority of the deck is about 3 or 4 feet above the ground
surface.
The subject house is situatxl near the crest of a steep slope that is approximately 100 feel high,
above the 13NSF railroad and Puget Sound to the west. You provided its with a copy of the Critical
Anxis Reconnaissance Report, prepared by City Planner Keenan Lien on September 10, 2008. I'hc
City considers the slope an erosion hazard area, and possibly a landslide hazard area. Any work on
your properly that rotloires a City pennit roust arldress ❑ppropriale sections of 1.l'IX, (Iitlmunds
Community Dcvelopmcnl Code) seclion;; 23.40 and 2.i.80.
You indicated Thal Mr. Licn rcicrred you ru Ciry Development lufinrrurtiuu I'adwt 1I1.121, which
slates, "Forsingle.laarily residences. a prrarit is required n-the construrtkrn, repair, rate/accnamt.
relocation, addition, ar alteration o/ narks• that are greater than ;il inches above gran,." Strict
application ol'lhis language on your proposed project resulted in a detenninalion that a permit is
required. in our opinion, because you are not planning any structural alteration of your deck,
requiring a pennit seems ovox-reaching and goes beyond the spirit and intent oh
the code. if a homeowner wanted to re -paint her deck, or apply self-adhesive c
anti-skid strips to the stair treads, would such activities be considered `repair" ;,,,,,I. TO
and subject to a pennit? Or in other words, how is repair defined? For this

reason, we suggest that you seek clarification and/or a waiver of the deck permit requirement.
That issue notwithstanding, this letter report is intended to satisfy the City's requirement for
gentechnical engineering evaluation of the project in the context of FCDC 23.40 and 23.80.
General Geology
Geologic mapping for the subject sites indicates that the subject house and bluff are underlain by
Vashon glacial till and advance outwash. Roth of these geologic units were over -ridden by a few
thousand feet of glacial ice. Un-weathered and un-disturbed glacial till and advance outwash
exhibits very high shear strength.
Previous Geotechnical Study in Project Vicinity
HWA is the gentechnical engineer for RNSF and Sound Transit on Segments A and 13 of the Seattle
to Everett Commuter Rail Project. In 2005, we advanced an exploratory boring at the base of the
subject slope on the cast side of the RNSF mainline, within a ample hundred feet of the Gordon -
Goodman property. At that location, our boring encountered a veneer of about 7'/z feet of
loosened/weathered silty sand (colluvium); overlying dense to very dense clean to silty sand (un-
weathered native advance glacial outwash), which extended down below sea level.
Observations at the Crest of the Slope and Below the Deck
The ground surface below the deck and extending an average of about 10 feet west of the deck is a
relatively flat, well -maintained landscaping area. Beyond this area, the ground surface slopes
steeply down toward the RNSF railroad. The undersigned geotechnical engineer did not observe
any tension cracks, leaning hedges or trees, or other signs of recent or potentially imminent slope
movement in the area observed. There was no evidence of any uncontrolled surlilcc water erosion
runoff, and there was no evidence that yard clippings or other debris were being disposed onto the
slope.
A very brief inspection of the deck substructure was undertaken. The drek joists appear to he
extensions of the floor joists in the house. Much of the deck is supported on caolilevered floor
joists extending west fi-om the house. I IOWUVer, iu the main enlarged area of the deck, That wat;
built up around an existing large coniferous (fir or similar) tree, there are it 1'ew 4x4 posts on
concrete piers hearing on the level ground below the deck.
Slope Stability
The core of the slope below the house is composed of dense granular material, and deep-seated
landsliding is extremely unlikely.

However, due to season fieezelthaw and wetting/drying cycles, gopher and mountain beaver
burrows, plant rooting, and other natural factors, the surface of the slope will weather and weaken
over time. The depth of weathering will typically be limited to within a few feet of the slope
surface. A potential exists for shallow surficial sliding of the weakened and eroded native soils.
These slopes and bluffs will normally be stable for years or decades until an extreme period of wet
weather, earthquake, and/or other destabilizing influence causes a shallow skin slide. An example
of this was the winter 1996/1997 rain -on -snow event where several shallow skin slides originating
on bluffs, causing extensive property damage to properties situated below the slide,.. Over a period
of several decades, experience has shown that dense granular, ocean -facing bluffs in the Puget
Sound region, such as the slope below your house, exhibit an average rate bluff retreat of about 2 to
4 inches per year.
Your house and deck posts are set hack approximately 10 feet or more from the crest of the very
steep slope. Therefore, in our opinion, the house and deck are not currently at risk of damage from
shallow skin sliding. As the property owners, you are obviously invested in taking measures to
keep the subject slope stable. Such measures include:
Eliminating any and all uncontrolled surface water runoff from flowing toward the slope;
tight lining all roof downspout runoff away from the slope; and
not dumping yard clippings or any other debris onto the slope.
Conclusions and Recommendations
No Impacts to Subject or Adjacent Property: As we understand, the proposed deck
modifications involve replacing existing wood decking with composite plastic decking material, and
replacing the existing wooden handrails with stainless steel cables. The existing deck substructure
would remain intact without modification. Because the existing deck will not be enlarged and the
existing sub -structure will not be modified, the proposed resurfacing and hand rail replacement will
result in insignificant changes to the deck pier and house foundation loads. Therefore, it is our
opinion that the proposed deck alterations will have no impact the stability of the slope and all
adjacent properties.
Project May Be Excmpl of Critical Area Requirements: Prom oor review of 1?C DC23.40.2 30,
subsection C(2), your proposed deck prgject is probably exempt ofthe Cily's Critical Area
requirements. This subsection slates that an exemption applies in Ilic hollowing situation:
"Operation, maintenance, at- repair of existing structu es, infi-aviructure improve news, utilities,
public or private roads, dikes, levees, at- drainage s'Vvtems that do not require construction permits,
if the activity does not further alter or increase the inipact to, at, encroach.ia-titer within, the
critical area hu/fer and there is tin increased risk to Ir/e or properq, as a result of the proposed
operation, maintenance, or repair. " We recommend, therefore, that you meet with the City Planner
and request an exemption from any further Critical Areas review or permit requirements.

Limitations
5'his report was prepared exclusively for Patricia Gordon -Goodman, for specific application to this
project and purpose. Our scope of work included a visual assessment and review of existing
gootechnical information. Exploratory borings or other intrusive testing on the subject properly
may indicate other conditions that are not apparent in a visual inspection. The interpretations in this
report should not be construed as our warranty of the subsurface conditions. Experience has shown
that soil and ground water conditions can vary significantly over small distances. If, during future
site operations, subsurface conditions are encountered which vary appreciably from those described
herein, HWA should he notified for review of the recommendations of this letter report, and
revision of such if necessary.
The scope of work did not include environmental assessments or evaluations regarding the presence
or absence of wetlands or hazardous substances in the soil, surface water, or ground water at this
site.
We appreciate the opportunity to provide geotechnical engineering services. Ifyou have any
questions, or if we may be of further assistance, please do not hesitate to contact the undersignexl at

To whom it may concern.
The tree in question is a Douglas Fir tree positioned on the west side of John Goodmans' home,
located at 18420 Olympic View Dr in the city of Edmonds.
This tree has two fractures in the trunk of the tree, noticeable from the outside of the tree. The
bark and cambium have separated because of the fracture.
NW Arbor care has done several windsail reductions throughout many years. Upon inspection of
the tree last year, the fractures were noticed.
In my professional opinion, this tree is a hazard and dangerous tree that needs to be removed
If you have any questions, Please give me a call.
