Arlington, WA 98223
Dear Ms. Gonzales:
On March 20, 1998, you submitted a critical areas checklist for your property at 7003 —
156th Street SW. In reviewing our records, we found that a critical areas determination
has already been made for that address under critical area . s file CA-94-98. That
determination was that a steep slope hazard area was on the site, and required that a
topographic survey prepared by a licensed land surveyor delineate the steep slope hazard
areas (see attached). Since the determination was made, the definition of steep slopes has
been changed. Under our current regulations, you are required to do the following.
To detern-iine if a Steep Slope Hazard Area does exist, a topographic survey prepared by a
Licensed Land Surveyor delineating Steep Slope Hazard Areas must be completed. Any
slope of 40% or more with at least 20 feet of rise will be classified as a Steep Slope
Hazard Area. A 50-foot buffer is required from both the top and toe of the slope. A 15-
foot building setback is required from the 50-foot buff�r.
For development of any kind which is proposed within the critical area, 50-foot buffer or
15-foot buffer setback, it must be shown that the development will not adversely impact
the Critical Area or its buffer, by doing one or possibly both of the following depending
on the outcome of the study:
For development proposals which will occur within the 50-foot buffer, but no
closer than 25 feet from the top or toe of the slope, the 50-foot buffer requirement
may be reduced to 10 feet if a study is completed by a licensed geologist or
geotechnical engineer which clearly demonstrates that the proposed buffer
alteration will have no adverse impact upon the site, the public or any private
party. All Critical Area Studies, except those done by a licensed geotechnical
engineer, must be completed under a three party contract where the City hires the
professional required, and the applicant pays for the study (pursuant to ECDC
Section 20.15B. 150).

2. If development must occur within the critical area, buffer, and/or buffer setback,
and is not identified as an exception per ECDC Chapter 20.15B, a Reasonable Use
Exception and Variance must be obtained pursuant to ECDC 20.15B. 170A and
20.15B.040C.
All proposed development of the subject lot must meet the requirements of Chapter 19.05
(Building Permits - Earth Subsidence and Landslide) of the Edmonds Community
Development Code.
If a property owner wishes to apply for a specific development permit which they feel
would not impact the Critical Areas located on the site, they may submit their proposal to
the Planning Department for review. If the Planning Department finds that the proposed
development permit will not adversely impact a Critical Areas or its buffers, a conditional
waiver may be issued on a project by project basis.
With your checklist, you also submitted a sketch showing the approximate top of slope.
The map has not been stamped by a surveyor, and it does not make it completely clear if
there is a steep slope on site, where it is located, or where the buffer and building setback
for the steep slope are.. Before you can apply for a building permit or other permit
application, we will a need a topographic survey prepared by a Licensed Land Surveyor
delineating the 9teep Slope Hazard Area, buffer and building setback.
If you have any questions, please call me at (425) 771-0220.
Sincerely,
Meg Gruwell

The existing residence has been identified as being in a Critical Slope Area per the City of
Edmonds and must meet the requirements outlined in City of Edmonds Code, Section 19.05.
The following information is in regards to the existing residence and the addition noted above.
The project is an addition to an existing residence located on flat ground, the addition -will also
be located on flat ground. The issue is the proximity of the addition to the top of the existing
slope. Per the City of Edmonds Critical Areas Site review conducted for this site a
Geotechnical Report and Topographic Survey, each prepared by a Licensed Washington
State Engineer, where required. These items have been provided and based on this
information the Geotechnical Engineer has recommended Construction of the addition would
have no adverse impacts on the existing slope provided the footing bearing point is taken to
depth of at least 6'-0" and into the dense to very dense drift line of soil. Also in the report
recommendations for slope protection and grading have been included. The addition shall be
constructed per these recommendations.
The Soils Engineer has identified the on site natural slope average as 33% and it descends a
vertical distance of +t- 33'-0", this determination was- reached through on site investigation.
See attached soils report dated October 1, 1998. The City of Edmonds Code by definition
requires both the slope to be greater than 40% and the vertical, distance to be over 20'-0" to
qualify as a Steep Slope Hazard Area. Also, per City of Edmonds Staff interpretation the
slope shall be based on the original grades of the property, therefore the onsite conditions
would not qualify the site as a Steep Slope Hazard Area. It is not until farther North, off the
Stolzenburg's property, that both these conditions occur. The natural slope, per the
Geotechnical Report prepared by Nelson-Couvrette Engineering, does not exceed 33% until
approximately 240'-0" from the proposed Northerly Addition. This area is beyond the.
Stolzenburg's northerly property line and is not in their control, it is a county park.
The proposed construction, as located, has no potential for adverse impact on adjacent
property owners, public improvements, or the public in general and meets the requirements
stated in City of Edmonds Community Development Code Section 19.05.000 Preamble -
Statement of Purpose. The proposed addition does not restrict neighboring views or other
existing structures. The property to the North and East of the existing residence is
greenbelt/park land and heavily vegetated. There area noresidences located adjacent to the

Dear Ms. Gonzales:
This letter is being written in response to your letter regarding 7003 — 1561h St. SW
in Edmonds. Specifically, your letter is in response to a determination that was
made concerning setbacks and an addition that you are proposing for the residence.
Earlier this year you and I had discussed a Critical Areas Checklist Determination
of a "Study Required" for 7003 — 156 Ih St. SW in Edmonds. This determination
required that a topographic survey be submitted as well as a top of slope identified
for setback purposes. While this information appears to have been provided I now
understand that there is some confusion as to the definition of top of slope. I hope
that I am able to clarify exactly the required setbacks and how the city must
interpret a top of slope determination.

North or East due to the park area. The above noted policy also states that permits can be
issued in areas suspect of landslide hazards if specific requirements are meet. Per the Soils
Report and the Survey the site has been established to be within acceptable limits and design
criteria for stable construction has been established. The Soils Report recommendations for
construction methods shall be incorporated into the construction documents, the structure
shall be designed and stamped by a Structural Engineer licensed in the State of Washington,
and reviewed by the Soils Engineer for compliance with the Soils Report.
Due to slope setback, BSBL, and the existing residences's location the lot area for expansion
is limited. The location of the proposed addition is based on the overlay of all required
setbacks onto the site and the existing residence's exterior and interior configuration. A 10'
side, rear and front yard setback apply to the entire perimeter of the property due to the flag
lot status of the site. The 25' slope set back greatly restricts the site use and eliminates +/-
65% of the total lot area. The addition as proposed meets the BSBL and the 25'-0" slope
setback per 1997 UBC Chapter 18. The 1997 UBC Section 1806.5.3 and Figure 18.1.1
indicate the footing setback requirement from the slope be measured 90 degrees to the
footing at the footing bearing elevation. The footing depth and angle of bearing influence when
measured at 90 degrees to the slope are greater than 26-0". Also section 1806.5.3 states
that for descending slopes over 1 to 1 slope use the maximum measure of 45 degrees.
Measured in an imaginary plane 45 degrees to horizontal projected upward from the toe of the
slope. By following these UBC requirements the line of the recommended footing depth and
the 45 degree slope intersect approximately 225'from the proposed addition, thus also
satisfying the UBC setback requirement.
Based on the Geotechnical Report, the Survey, the above information, and site plan the
proposed addition should not be subject to Steep Slopes Hazard Area requirements. The
proposed residential addition is a distance of 25'-O'from the slope when the setback distance
to the addition is measured at the footing depth per, 1997 UBC, Section 1806.5.3 and Figure
18-1-1 and the footing depth is increased as directed by Nelson - Couvrette's Geotechnical
Engineering Report. Therefore it is requested that the addition be designated incompliance to
the Steep Slope Hazard Area setback based on the slope setback measurements as
determined per 1997 UBC requirements and subject to the permit submittal requirements as
identified in The City of Edmonds Development Code, Section 19.05.
Thank you for your help in processing this application and I look forward to working with you
as this project progresses. If you have any questions please contact me at 360-435-5514.

Dear Mr. Stolzenburg:
INTRODUCTION
Snohomish County (425) 337-1669
Wenatchee/Chelan (509) 784-2756
This report presents the results of our preliminary engineering geologic investigation at the site located at
7003 — 156h Street SW in Edmonds, Washington, as shown on the Vicinity Map in Figure 1. You have
requested. that we evaluate the existing site conditions, and provide recommendations for future
development and construction within the area. For our use in preparing this study, you have provided us
with a copy of the City of Edmonds Critical Areas requirements, a copy of the City of Edmonds letter,
dated March 20, 1998, an undated copy of a drawing titled "Slope Exhibit — Dr. D. Sto lzenburg", a copy
of a cross section titled "Stolzenburg", dated June 10, 1998, a copy of an undated, untitled site plan, and a
copy of a legal description and- information from a previous plat submittal.
The project consists of an addition to an existing one-story, single-family residence located near the top of
a steep slope. The addition will extend approximately 13 feet off the north side of the existing structure,
as shown on the Site Plan in Figure 2. The north end of the addition will be approximately 10 to 20 feet
from the top of the steep slope.

SCOPE
The services provided by NCA at this time are as follows:
I . Review existing soils and geologic maps, and related data.
2. Perform backhoe-excavated test pits and slope mapping at the site, to document the
subsurface. soils and ground water conditions.
3. Reduce field data through use of your provided site plan.
4. Present an evaluation of geologic hazards of existing site conditions and future site
development.
5. Provide an engineering geologic report discussing our findings, opinions and any
recommendations related to our analysis and findings.
SITE CONDITIONS
Surface
The project site consists of a rectangular- shaped parcel and is shown on the Site Plan in Figure 2. The
proposed addition is located above a steep, northerly slope overlooking Lunds Gulch. The southern
portion of the site is flat lying, landscaped, and is occupied by a single-family residence. The top of the
steep slope is located approximately 20 to 33 feet north of the residence. Approximately 10. feet below
the top of slope, a pathway has been benched into the hillside. This portion of the slope has also been
landscaped. Below the pathway, the ground slopes down steeply to Lunds Gulch. This portion of the
slope is vegetated with brush, ferns, deciduous trees, and scattered evergreen trees and old growth stumps.
We measured one cross-section (A -A') through the slope, as shown on Figure 3. The cross section was
measured using a hand-held clinometer and a 100-foot measuring tape. Below -the top of slope, the
ground surface slopes down at about 42 percent to the pathway. Below the pathway, the ground surface
slopes down at about 33 to 49 percent. About mid -way down the slope, the inclination steepens to
approximately 68 to 78 percent, and continues with this inclination to the toe of the slope. We measured
a total change in elevation on the order of 270 feet, with an average inclination of about 58 percent.
Geology
Most of the Puget Sound Region was affected by past intrusion of continental glaciation. The last period
of glaciation, the Vashon Stade of the Fraser Glaciation, ended approximately 10,000 to 11,000 years ago.
NELSON-COUVRETTE & ASSOCIATES, INC
Engineering Geologic Report
Stolzenburg Addition
October 1, 1998
NCA File No. 241498
Page 3
Many of the topographic features seen today are a result of scouring and overriding by glacial ice. During
the Vashon Stade, the Puget Sound region was overridden by over 3,000 feet of ice. Soil layers
overridden by the ice sheet were compacted to a much greater extent than those that were not. A typical
glacial sequence includes recessional outwash sand overlying glacial till.
The geologic units mapped for this area are shown on the Preliminary Surficial Geologic Map of the
Edmonds East and Edmonds West Quadrangle, Snohomish and King Counties, Washington, by Mackey
Smith (U.S.G.S., 1975). The site vicinity is mapped as glacial till (Qvt), with Whidbey Formation (Qw),
and Double Bluff Drift (Qdb) mapped on the slope. Glacial till is a dense, unsorted mixture of sand, silt
and gravel deposited at the base of the continental glaciers. The Whidbey Formation is massive to bedded
silts, clayey silts and fine sands that were deposited in an interglacial lacustrine environment then over-
ridden and consolidated by the continental glaciers. Double Bluff Drift may consist of dense cemented
gravel in a silty sand matrix, pebbly glaciolacustrine silts, or massive silts with occasional small beds of
sand and gravel. Our explorations encountered fill and glacial drift. Glacial drift is similar to till, but
typically has some sorting, such as sand seams, and is less dense than till. We would expect that the
Whidbey Formation and Double Bluff Drift are located at depth underlying the drift.
Subsurface Conditions
The s ubsurface conditions at the site were explored on August 27, 1998. Two test pits were excavated
with a rubber -tired, tractor -mounted backhoe. The depths of the backhoe test pits ranged from 8 to 9 feet
below the existing ground surface. The approximate locations of the test pits are shown on the Site Plan
in Figure 2. A geologist from our firm was present during the explorations, examined the soils and
geologic conditions encountered, and maintained logs of the test pits. The soils were visually classified in
general accordance with the Unified Soil Classification System, a copy of which is shown on Figure 4.
The logs of the test pits, edited to reflect examination of soil samples in our laboratory, are shown on
Figure 5.
Our explorations encountered a surficial layer of sod approximately 0.3 feet in thickness. We
encountered approximately 2.5 to 3.0 feet of fill underlying the sod. The fill consisted of loose, fine to
coarse sand with silt, gravel, cobbles, a clay drain pipe, and roots. Underlying the fill, we encountered a
0.5-foot-thick layer of buried topsoil. The topsoil consisted of loose, silty fine sand with organics and
roots.

Pag e 4
We encountered a 3-foot-thick layer of dense, fine to coarse sand with gravel and cobbles underlying the
buried topsoil in Test Pit 2. Underlying the buried topsoil in Test Pit I and the fine to coarse sand with
silt in Test Pit 2, we encountered dense, rust -stained silty fine to coarse sand with gravel and occasional
sand seams to the depths explored. We have interpreted these soils as glacial drift.
Hydrologic Conditions
Ground water seepage was not encountered in our test pit explorations or observed.along the slope face
during our site reconnaissance. We expect perched ground water conditions could develop during the
wetter months of the year. Perched water is a condition where water infiltrates through more permeable
soils, such as the fill and fine to coarse sand layer, then moves laterally along the surface of a less
penneable soil, such as the silty sand encountered in the drift. Perched water conditions are common for
upland areas underlain by till or drift, and tend to be seasonal. This type of, seepage condition tends to
decline markedly during the summer months.
GEOLOGIC HAZARDS
General
The area contains slopes between 33 to 78 percent that are underlain by glacial drift, and. inferred to be
underlain at depth by Whidbey Formation and Double Bluff Drift. We reviewed the Landslide Hazard
map from "Final Report, Landslide Hazards Investigation, Meadowdale Area, Edmonds, Washington", by
Roger Lowe Associates, Inc., dated October 16, 1979, to determine the landslide hazards that have been
mapped for the site. The Landslide Hazard map indicates that no hazards were identified in the southern,
flat -lying portion's of the site where the planned residential addition is located. The portion of the slope
that inclines down with 33 to 49 percent slopes was mapped as 3AO5. This means that the mapped area
has a 5 percent probability in the next 25 years to have a slump type failure in, material that has not
*previously failed. The upper portion of the slope that inclines down with 68 to 78 percent slopes was
mapped as 31302. This means that the mapped area has a 2 percent probability in the next 25 years to
have a debris slide type failure from encroaching landslide materials. The lower portion of the 68 to 78
percent slope was mapped as 2CO2. This means that the mapped area has a 2 percent probability in the
next 25 years to have a debris avalanche type failure from encroaching landslide materials.

Landslide Hazard
The core of the slope is inferred to be compromised of dense glacial drift, Whidbey Formation, and
Double Bluff Drift. These materials typically have high strength. We noted some soil creep at the site,
evidenced by some minor bowing in tree trunks. Deep-seated landsliding was not noted, and we expect
the site to be stable with respect to deep-seated slope failures. We expect the degree of soil creep is
largely controlled by the perched water flow through the more weathered soils. The potential of
landsliding affecting the structure on the site should not be significant.
Erosion Hazard
The erosion hazard criteria used for determination of affected areas include soil type, slope gradient,
vegetation cover, and ground water conditions. The erosion sensitivity is related to vegetative cover and
the specific surface soil types (group classification), which are related to the underlying geologic soil
units. The Soil Sury ey of Snohomish County Area Washington by the Soil Conservation Service (SCS)
was reviewed to determine the erosion hazard of the on -site soils. The surface soils were mapped by SCS
and classified as Alderwood-Everett (25 to 70 percent slopes) and Alderwood-Urban land complex (2 to 8
percent slopes) soils. We encountered glacial drift consistent with Alderwood soils during our
investigation. The erosion hazard for these soils is listed as being high for 25 to 70 percent slopes and
slight for 2 to 8 percent slopes.
Seismic Hazard
The seismic hazard is based on potential for liquefaction of the underlying soils. The site is underlain by
medium dense to very dense glacial drift/till. We expect the potential for liquefaction to be minimal for
structures founded on medium dense or better soils.
CONCLUSIONS AND. RECOMMENDATIONS
The City of Edmonds has designated the site as a critical area. , In our opinion, the subject site and the
moderate to steep slopes underlain by glacial drift, Whidbey Fori-nation, and Double Bluff Drift are
considered stable with respect to deep-seated slope failures. We did not observe any signs of significant
slope instability on the site. Seepage was not observed along the slope face at the time of our visit. In our
opinion, the 50-foot buffer requirement may be reduced by achieving an effective setback from the face
of the slope. These recommendations are outlined in the Structure Setback and Foundation
Embedments subsection of this report.

Erosion potential for the site may be reduced if temporary erosion controls are implemented during
construction, and any areas disturbed during construction are recompacted and revegetated. Where
vegetation is not disturbed during construction, the erosion potential should not be significant. Care
should be taken during construction to keep concentrated runoff off the slopes. Following construction,
roof and footing drains should be tightlined to the bottom of the slope and dispersed to minimize erosion,
I
or directed to an appropriate stonn water system.
The soils likely to be exposed during construction are highly moisture sensitive and will disturb easily
when wet. We recommend that construction take place during the drier summer months. However, if
construction takes place during the wet season, additional expenses and delays should be expected due to
the wet conditions. Additional expenses could include the export of on -site soil and the import of clean
granular soil for fill.
Slope Protection
Protection of the setback and steep slope areas should be performed as required by the City of Edmonds.
It should be understood that the closer the site disturbance and development of the structure are to the
slope, the more risk there is of affecting slope stability. Care should be taken to minimize disturbance to
the slope face and to the native undisturbed soils between the house and the top of slope. Fill should not
be placed between the house and the top of slope, or over the s.lope.
From an engineering geologic standpoint, selective pruning and thinning of vegetation should. be
acceptable. Cutting and pruning of trees located on the slope can be performed, if allowed by the City,
but certain precautions should be taken. We recommend that the root bundle/stump of felled trees be left
in place. Pruned materials and debris should be removed from the area, and not allowed to remain on the
slope. Any disturbed areas should be immediately restabilized through vegetation planting or other
approved means. Placement of soil, sod, clippings or other matter on the slope is not recommended.
Of great importance to the long-term stability of the slope is the control of surface and near -surface water,
and erosion protection. We recommend that all drains, including foundation, roof and yard drains, be
directed away from the top of slope, and.outfall at an approved area. Drainage over the slope should not
be permitted without specific- recommendations.

Site Preparation and Grading
The first step of site preparation should be to strip the surficial sod, fill and buried topsoil to medium
dense to very dense native soils in building areas. This material should be removed from the site, or
stockpiled for later use as landscaping fill. The underlying soils are considered highly moisture sensitive
and will disturb easily and become difficult to work with when wet. At the exploration locations, the
depth to medium dense to very dense drift was approximately 3.0 to 3.5 feet. Site grading should not
significantly increase the risk of erosion or slope failure if normal erosion control procedures.are followed
and water is kept off exposed slopes.
Structure Setbacks and Foundation Embedments
Uncertainties related to building along the top of steep slopes and, in particular, unstable or actively
backwasting slopes are typically addressed by the use of building setbacks. The purpose of the setback is
to establish a "buffer zone" between the structure areas and the top of the slope, so that ample room is
allowed for normal slope recession during a reasonable life span of the structure (usually taken to be 50 to
100 years by Snohomish County). In a general sense, the greater the setback, the lower the risk. From a
geological standpoint, the setback dimension is based on the slope's physical characteristics, such as slope
height, surface angle, material composition, and hydrology. Other factors such as historical slope
activity, rate of regression, and the type and desired life span of the development, are important
considerations as well.
Based upon the conditions described above, it is our opinion that the slope is relatively stable, and the 50-
foot buffer requirement may be reduced, provided foundations are placed sufficiently deep into the dense
to very dense drift. This can be done by deepenin g the foundation on the steep slope side of the house to
below the natural inclination of the slope. We have interpreted the natural inclination of the slope to be
the 33 percent slope line as shown on the cross section in Figure 3. Footings should extend through the
fill and buried topsoil, and bear into the underlying dense to very dense drift below this line. This would
require a footing embedment of about 6 feet below the existing ground surface. The foundation can step
away from the slope, such that the effective setback is achieved. The reduced setback will need review
and concurrence by the City of Edmonds.

Foundations
Conventional shallow spread footings are expected to be suitable for the structure founded into medium
dense to very dense native soils or structural fill extending to these soils. Design pressures, as stipulated
by the Uniform Building Code (UBC), should. be expected.
Specific design procedures for foundations and slab -on -grade may be dependant on final design. Specific
geotechnical issues could be delineated when final design is complete.
Structural Fill
All fill placed beneath buildings, pavements or other settlement sensitive features should be placed as
structural fill as required by the City of Edmonds codes. For the purpose of this report, structural fill is
defined as material that is placed in accordance with prescribed methods and standard and is monitored by
an experienced geotechnical professional or soils technician. Field monitoring procedures would include
th e performance of a representative number of in -place density tests to document the attainment of the
desired degree of relative compaction. The area to receive fill should be prepared as outlined in the Site
Preparation and Grading subsection of this report.
USE OF THIS REPORT
We have prepared this report of findings and preliminary recommendations for Mr. Dennis Stolzenburg,
and his agents, for use in this project. The scope of our work does not include services related to specific
construction activities, and final plans may dictate earthwork parameters. Since our work is considered
preliminary in nature, it should be understood that there are possible variations in subsurface conditions.
We recommend that project planning include contingencies in budget and schedule, should areas be found
with conditions that vary from those described in this report.
Within.the limitations of scope, schedule and budget for our services, we have strived to take care that our
work has been completed in accordance with the generally accepted practices followed in this area at the
time this report was prepared. No other conditions, express or implied, should be understood.

SOIL MOISTURE MODIFIERS
1 ) Field classification is based on
Visual examination of soil in general Dry- Absence of moisture, dusty, dry
accordance with ASTM D 2488-83. to the touch
2) Soil classification using laboratory Moist- Damp, but no Visible water
tests is based on ASTM D 2487-83.
Wet- Visible free water or saturated,
3) Descriptions of soil density or usually soil is obtained from
consistency are based on below water table
interpretation of blowcount data,
Visual appearance of soils, and/or
