2013-1003, Gill Foundation," dated October 2, 2013.

SW, Edmonds, WA 98026," dated 9/12/13, by Hayman Engineering.
Dear Ms. Pinder,
Robbins, and Company is proposing to underpin of a portion of the house foundation on the
northeastern side of the house.. The subject, residence is located at the top of a steep slope that is
identified as a landslide hazard area by the City of Edmonds. The' City has requested a
geotechnical hazards analysis to ensure that the scope of work will comply with the critical areas
ordinance. For this analysis, we reviewed the area geologic map, the area soil survey map and
the above referenced underpinning plan, Sheet S 1, and conducted a site visit on October 9, 2013.
Geology Review
According to the area geologic map' the soils in the project area consist of Glacial till (Qvt)
underlain by Advance outwash (Qva). These soils were deposited during the Fraser glaciation
period that ended some 12,000 years ago. Glacial till is mapped on the highland area above the
slope and soils on the upper portion of the slope are mapped as Advance outwash. Glacial till

consists of a -glacially consolidated mixture of sand, silt, clay and gravel deposited under glacial
ice. Advance outwash consists of glacially consol idated pebbly sand deposited by streams
issuing from the advancing ice sheet. The geologic map does not identify the site or.the slope as
a landslide area.
Soil.Survey Review
According to the Soil Survey of Snohomish County2, the soils are mapped as Alderwood-Everett
gravelly sandy loams, 25 to 70 percent slopes. The Alderwood-E verett gravelly sandy loam unit
is described as being on till plains, terraces, and outwash plains. It also includes colluvial -soils,
slump areas, and escarpments.. Based on the geology, the soil is classified as Everett soil, which
formed in glacial outwash sand and gravel -and is very deep, has a high permeability, ana has a
moderate water erosion potential.
Site Conditions
The steep slope is located on the northeast side of the house. The slope has an estimated gradient
of around 40. percent. The slope is vegetated with trees, except below the house which is
vegetated with blackberry vines. The blackbe rry area may have been previously cleared.
The top of the slope is located about 12 feet from the north comer of the house and the top of the.
slope extends further from the house to the southeast. A relative level concrete patio area is
located between the house and top of slope. A wood fence is located along the top of the slope.
A 4 foot long 1/2-inch steel rod,was used to probe the soils next to the house and along the top of
the slope. Loose soil is present along the top of the slope. Dense soil was encouxitered at a depth
of 3.5 to 4 feet at the north comer of the house.
Underpinning Scope
Underpinnig the house will require hand excavation next to the house foundation to install the
pin. piles. The work will be performed on the level ground within the steep slope buffer.

Excavation to install the pin piles will be limited in size and the excavated soil will be
temporarily stockpiled next to the excavation. Upon completion of the pin pile installation the
excavation will be backfilled with the stockpiled.soil. During wet weather we recommend that
stockpiled soil be covered with plastic for erosion protection.
Conclusions
No scarps, tension cracks, or other signs of slope instability were observed above the top, of the
slope or on. the upper portion of the slope below the house during our reconnaissance. The slope
generally appears to be stable. Based on the geology, the site conditions observed and the limited
scope of the proposed underpinning work, it is our professional opinion that the proposed scope
of the underpinning work will not harm the critical area or adjacent property.
In Accordance with ECDC 23.80.070.A.2. it is our professional opinion that:
A. The proposed underpinning work will not increase surface water discharge or sedimentation
to adjacent properties beyond the conditions prior to the start of work;
B. The proposed work will not decrease slope stability on adjacent properties; and,
C. Such alterations will not adversely impact the steep slope critical area or other critical areas.
LUMTATIONS
'This report has been prepared for the specific application to the subject project. The findings and
recommendation& stated herein are based on the literature reviewed, our field. observations, and
our experi.ence.-and judgement. The recommendations are our professional opinion derived in a
manner con I sistent with the level of care and skill ordinarily exercised by other members of the
profession currently practicing under similar conditions in this area and within the budget
constraint. No warranty is expressed or implied.

RE: Address Change
LAURA M. HALL
MAYOR
PETER E. HAHN
DIRECTOR
I have contacted the City Building Official and the City Fire Inspector
in response to your request for re -addressing your house to 6817 157th
PI SW and we have all concurred that new addressing needs to be done.
The house permit was issued under 6821 157th Pl SW, but it is the
City's understanding that all subsequent paperwork (mortgage$ etc.) was
issued under 6817 157th PI SW and that the house numbers were posted as
6817. City records and utility billing are the only departments that
have ever used 6821 157th PI SW. Therefore, your address will be
changed, per your request.
The City will notify all applicable City departments of this address
change. It will be your responsibility to notify all others, including
the Post Office, if necessary.
Thank you,
Sharon Nolan
