CRITICAL AREAS RECONNAISSANCE REPORT
Site Location:

Tax Acct. Number:
00594400004202
Determination:
Study Required
Determination #:
CA-06-22
Applicant:
John Fosberg
Owner:
John Fosberg
CRITICAL AREAS RECONNAISSANCE REPORT: STUDY REQUIRED (CA-06-22)
During review and inspection of the subject site, it was found that the site may contain critical areas,
including Geologically Hazardous areas, pursuant to Chapters 23.40 and 23.80 of the Edmonds
Community Development Code (ECDC).
GENERAL CRITICAL AREAS REPORT REQUIREMENTS
Critical Areas Reports identify, classify, and delineate any areas on or adjacent to the subject
property that may qualify as critical areas. They also assess these areas and identify any potential
impacts resulting from your specific development proposal. If a specific development proposal results
in an alteration to a critical area, the critical areas report will also contain a mitigation plan. You have
the option of completing the portion of the study that classifies and delineates the critical areas and
waiting until you have a specific development proposal to complete the study. You may also choose
to submit the entire study with your specific development application.
Please review the minimum report requirements for all types of Critical Areas that are listed in
ECDC 23.40.090.D. There are additional report requirements for different types of critical
areas (see below).
Note that it is important for the report to be prepared by a qualified professional as defined in
the ordinance. There are options on how to complete a critical areas study, and there is an
approved list of consultants that you may choose from. You may contact the Planning
Division for more information.
General Mitigation Requirements for all Critical Areas are discussed in ECDC 23.40.110
through 23.40.140.
STUDY REQUIREMENT — EROSION HAZARD AREA
It appears that this property contains or is adjacent to an Erosion Hazard Area. Erosion Hazard
Areas include:
0 Those areas with Alderwood and Everett series soils on slopes of 15 percent or greater.
Any area with slopes of 15 percent or greater and impermeable soils interbedded with
granular soils and springs or ground water seepage.
Areas with significant visible evidence of ground water seepage, and which also include
existing landslide deposits regardless of slope.
DEVELOPMENT PROPOSALS ASSOCIATED WITH EROSION HAZARD AREAS
Development within an Erosion Hazard Area must meet additional criteria.
For erosion hazard areas with suitable slope stability, the only critical area study needed is an
erosion and sediment control plan prepared in compliance with the requirements set forth in
a I
0 0
Chapter 18.30 ECDC as part of the construction documents. This option is at the director's
discretion, per Edmonds Community Development Code section 20.80.050.G.
In areas where the slope stability is not suitable, projects within Erosion Hazard Areas will
require a report by a licensed Geotechnical Engineer or other qualified professional. Note that
it is important for the report to be prepared by a qualified professional as defined in the
ordinance.
0 Report requirements are given in ECDC 23.80.050, and more generally in ECDC 23.40.090.D.
0 Development standards are given in ECDC 23.80.060 and 23.80.070.
STUDY REQUIREMENT — LANDSLIDE HAZARD AREA
It appears that this property contains or is adjacent to a Landslide Hazard Area.
A Landslide Hazard Area is any area with a slope of forty percent (40%) or steeper and with a
vertical relief of ten (10) or more feet (except areas composed of consolidated bedrock).
0 Landslide Hazard Areas are further defined and illustrated in ECDC 23.80.020.B.
In addition to the general requirements for Critical Areas reports referenced above, specific
Critical Area report requirements for Landslide Hazard Areas are provided in ECDC
23.80.050.
DEVELOPMENT PROPOSALS ASSOCIATED WITH LANDSLIDE HAZARD AREAS
Development is restricted within a Landslide Hazard Area and its buffer.
Projects that will intrude into these areas will require a report by a licensed Geotechnical
Engineer.
0 The criteria that are applied depend on the amount that the buffer is reduced.
The buffer can be reduced to a minimum often (10) feet (with an additional 15' building
setback per ECDC 23.40.280) if a report is prepared that meets the standards listed in ECDC
23.80.050. The alteration must also meet the requirements listed in ECDC 23.80.060.
In addition, proposals to reduce the buffer to less than ten (10) feet must comply with the
design standards listed in ECDC 23.80.070.A.3.
ALLOWED ACTIVITIES
Certain activities are allowed in or near critical area buffers as specified in ECDC 23.40.20. If you
have any questions about whether your proposed development qualifies as an allowed activity, please
contact a Planner for more information.
EXEMPT DEVELOPMENT PROPOSALS
Certain development proposals may be exempt from Critical Areas Requirements (ECDC 23.40.230).
If you think that a specific development proposal may be exempt, contact a Planner for more
information.

Proposed Addition — Existing Single Family Residence
17966 Talbot Road
Edmonds, Washington
Dear Mr. Steele:
KA Project No. 092-07039
Per the request from the City of Edmonds, we have prepared this addendum letter regarding the proposed
decks on the northern and southern sides of the residence. It is our understanding that the proposed decks
to be constructed will be a 12' X 14' deck at the front of the house and a 6' X 8' deck at the back of the
house.
Based on our site observations, our Limited Geologic Hazard Evaluation and Recommendations Letter
dated April 12, 2007, and our understanding of the proposed deck locations, the proposed deck to be
located at the back of the house should have a minimum setback of 20 feet from the top of the designated
critical'slope area. The proposed deck to be located in the front of the house should have a minimum
setback of 15 feet from the top of the existing slope area.
We hope that this letter provides the information required at this time. If you have any questions, or if
we may be of farther assistance, please do not hesitate to contact our office at (425) 485-5519.

RE: Limited Geologic Hazards Evaluation and Recommendations
Proposed Addition — Existing Single Family Residence
17966 Talbot Road
Edmonds, Washington
Dear Mr. Steele:
KA Project No. 092-07039
This letter report presents the results of our Limited Geologic Hazard Evaluation and Recommendations
for the referenced project. A Krazan & Associates senior project geologist visited the site on April 6,
2007.
PURPOSE AND SCOPE
We have prepared this letter to address the applicable elements of the Edmonds Municipal Code —
Natural Resources — Chapter 23.80 — Geologically Hazardous Areas. In preparation of this report, we
have reviewed the published geologic information for the site and performed a limited subsurface
exploration program to evaluate the existing shallow soil conditions. A visual assessment of the site
vegetation, slopes, and surficial conditions was also performed.
PROPOSED CONSTRUCTION
We understand that the proposed construction includes an approximately 300 to 400 square foot addition
to the western end of the existing structure. We understand that additional perimeter footings will be
placed to provide foundation support for the addition.
SITE LOCATION AND DESCRIPTION
The site is located at 17966 Talbot Road in Edmonds, Washington (Parcel No.00594400004202). The
property is nearly rectangular with a total area of approximately 16,000 square feet. The area of the
proposed addition is currently developed with a concrete patio slab and deck areas. The majority of the
site is gently sloping and vegetated with grasses and typical residential landscaping. A slope area is
located along the western property line and extends downward to the west at magnitudes of up to 80
percent. This slope is approximately 15 feet tall and is vegetated with trees, vines, and brush. The site is
bordered to the south, east, and west by residential structures, and to the north by Tal JZDad

GEOLOGIC SETTING
KA No. 092-07039

Page 2 of 8
The site lies within the central Puget Lowland. The lowland is part of a regional north -south trending
trough that extends from southwestern British Columbia to near Eugene, Oregon. North of Olympia,
Washington, this lowland is glacially carved, with a depositional and erosional history including at least
four separate glacial advances/retreats. The Puget Lowland is bounded to the west by the Olympic
Mountains, and to the east by the Cascade Range. The lowland is filled with glacial and nonglacial
sediments consisting of interbedded gravel, sand, silt, till, and peat lenses.
The Geologic Map of the Edmonds East and part of the Edmonds West Quadrangles, Washington,
indicates that the site is near the contacts of Vashon Glacial Till and Vashon Advance Outwash. Vashon
Glacial Till is typically characterized by an unsorted, nonstratified mixture of clay, silt, sand, gravel,
cobbles and boulders in variable quantities. These materials are typically dense and relatively
impermeable. The poor sorting reflects the mixing of the materials as these sediments were overridden
and incorporated by the glacial ice. Vashon Advance Outwash deposits are typically dense to very dense,
and composed of sand and gravel with minor amounts of silt and clay.
FIELD INVESTIGATION
A field investigation consisting of excavating one hand excavation adjacent to the area of the proposed
foundation system was completed to evaluate the shallow subsurface soil conditions. We encountered 2
inches of grass and topsoil underlain by medium dense, fine to medium grained sand with variable
amounts of gravel. These materials are consistent with Vashon Advance Outwash. Local T-probing of
the steep slope area indicated medium dense or firmer soil conditions.
GEOLOGIC HAZARDS
Landslide/Slope Hazard
An approximately 80 percent magnitude slope is located 15 feet from the proposed addition (western
end). This slope is up to 15 feet tall, and is currently vegetated with trees, vines, and brush. We did not
observe evidence of past slope movement, and there is no evidence of likely future movement. There are
other slope areas on, and adjacent to, the subject property; however, they are generally less than 10 feet
in height and have relatively low slope magnitudes.
Erosion Hazard
The Natural Resources Conservation Service maps indicate that the site is near the contacts of
Alderwood-Urban land complex and Alderwood gravelly sandy loam. The Alderwood-Urban land
complex is a soil unit typically derived from glacial till. The Alderwood gravelly sandy loam is a soil
unit typically derived from outwash materials. These soils are described as having "Slight" to
"Moderate" erosion potential in a disturbed state.
It has been our experience that soil erosion potential can be minimized through landscaping and surface
water runoff control. Typically erosion of exposed soils will be most noticeable during periods of rainfall
and may be controlled by the use of normal temporary erosion control measures, i.e., silt fences, hay

bales, mulching, control ditches or diversion trenching, and contour furrowing. Erosion control measures
should be in place before the onset of wet weather, if any grading occurs outside of the structure.
Seismic Hazard
It is our opinion, based on the overall density of the soils encountered in the subsurface explorations, that
the Soil Profile in accordance with Table 1615. 1.1 of the 2003 International Building Code (IBC) is Soil
Class C. We referenced the 2002 map from the U.S. Geological Survey (USGS) website to obtain values
for Ss and S1. The USGS website includes the most updated published data on seismic conditions. The
site specific peak ground accelerations, seismic design parameters, and adjusted maximum spectral
response acceleration parameters are as follows:
Peak Ground Acceleration (PGA)
30.48 (10% probability of exceedance in 50 years)
54.33 (2% probability of exceedance in 50 years)
Ss 121.90% of g
S, 42.77% of g
FA 1.0 From Table 1615.1.2(l) of the 2003 IBC
Fv 1.37 From Table 1615.1.2(2) of the 2003 I13C
Additional seismic considerations include liquefaction potential and amplification of ground motions by
soft soil deposits. The liquefaction potential is highest for loose sand with a high groundwater table.
The relatively dense soils interpreted to underlie the site are considered to have a low potential for
liquefaction and amplification of ground motion.
CONCLUSIONS AND RECOMMENDATIONS
The proposed addition to the residence may be located as proposed, approximately 15 feet from the steep
slope west of the residence. It is our opinion that this distance provides an adequate setback and buffer
during and following construction, provided adequate erosion control measures are in place during
construction. The addition may be supported on continuous footings placed on the medium dense native
soils, or on compacted structural fill placed on the suitable soils. Re -compaction of the footing subgrade
soils should be performed following excavation and prior to concrete placement.
We found no evidence of a landslide hazard, and recognize that the soils present a limited erosion hazard.
It is our opinion, based on our site observations and knowledge of the proposed construction, that
subsurface exploration and detailed slope stability analyses are not required. It is also our opinion that
detailed survey work and geotechnical analyses for the site slope conditions are not warranted.

Foundation Support
KA No. 092-07039
April 12, 2007
Page 4 of 8
The proposed structure may be supported on a shallow foundation system bearing on the medium dense
or firmer, native soils, or on properly compacted structural fill placed on the suitable native soils.
Continuous wall or column footings may be designed for a net allowable bearing pressure of 2,500
pounds per square foot (psf) dead plus live load, if the footings bear directly on medium dense or firmer
native soils, or on structural fill placed on the suitable native soils.
A 1/3 increase in the above values may be used for short duration, wind and seismic loads. Structural fill
placed on bearing, native subgrade should be compacted to at least 95 percent of the maximum dry
density based on ASTM Test Method D1557. Footing excavations should be inspected to verify that the
foundations will bear on suitable material.
Exterior footings should have a minimum depth of 18 inches below pad subgrade (soil grade) or adjacent
exterior grade, whichever is lower. Interior footings should have a minimum depth of 12 inches below
pad subgrade (soil grade) or adjacent exterior grade, whichever is lower. Footings should have a
minimum width of 12 inches regardless of load.
If constructed as recommended, the total settlement is not expected to exceed I inch. Differential
settlement, along a 20-foot exterior wall footing, or between adjoining column footings, should be less
than 1/2 inch, producing an angular distortion of 0.002. Most settlement is expected to occur during
construction, as the loads are applied. However, additional post -construction settlement may occur if the
foundation soils are flooded or saturated or if a strong seismic event results in liquefaction of the
underlying soils. It should be noted that the risk of liquefaction is considered low, given the composition
and density of the native, on site soils.
Seasonal rainfall, water run-off, and the normal practice of watering trees and landscaping areas around
the proposed structures, should not be permitted to flood and/or saturate footings. To prevent the buildup
of water within the footing areas, continuous footing drains (with cleanouts) should be provided at the
bases of the footings. The footing drains should consist of a minimum 4-inch diameter perforated pipe,
sloped to drain, with perforations placed down and enveloped by 1-inch sized washed rock in all
directions and filter fabric to prevent the migration of fines.
Resistance to lateral footing displacement can be computed using an allowable friction factor of 0.35
acting between the bases of foundations and the supporting subgrade. Lateral resistance for footings can
alternatively be developed using an allowable equivalent fluid passive pressure of 225 pounds per cubic
foot (pcf) acting against the appropriate vertical footing faces (neglect the upper 12 inches of exterior
soils). The allowable friction factor and allowable equivalent fluid passive pressure values include a
factor of safety of 1.5. The frictional and passive resistance of the soil may be combined without
reduction in determining the total lateral resistance. A 1/3 increase in the above values may be used for
short duration, wind and seismic loads.

Drainage and Landscaping
The ground surface should slope away from building pads and pavement areas, toward appropriate drop
inlets or other surface drainage devices. It is recommended that adjacent exterior grades be sloped a
minimum of 2 percent for a minimum distance of 5 feet away from structures. Roof drains should be
tightlined away from foundations and slope surfaces. Roof drains should not be connected to the footing
drains, but may use the same outfall piping if connected well away from the structure such that roof
water will not backup into the footing drains. Subgrade soils in pavement areas should be sloped a
minimum of I percent and drainage gradients should be maintained to carry all surface water to
collection facilities, and off site. These grades should be maintained for the life of the project.
Specific recommendations for and design of storm water disposal systems or septic disposal systems are
beyond the scope of our services and should be prepared by other consultants that are familiar with
design and discharge requirements.
Erosion and Sediment Control
Erosion and sediment control (ESQ is used to minimize the transportation of sediment to wetlands,
streams, lakes, drainage systems, and adjacent properties. Erosion and sediment control measures should
be taken and these measures should be in general accordance with local regulations. As a minimum, the
following basic recommendations should be incorporated into the design of the erosion and sediment
control features of the site:
1) Phase the soil, foundation, utility, and other work, requiring excavation or the disturbance of the
site soils, to take place during the dry season (generally May through September). However,
provided precautions are taken using Best Management Practices (BUT's), grading activities can
be undertaken during the wet season (generally October through April), but it should also be
known that this may increase the overall cost of the project.
2) All site work should be completed and stabilized as quickly as possible.
3) Additional perimeter erosion and sediment control features may be required to reduce the
possibility of sediment entering the surface water. This may include additional silt fences, silt
fences with a higher Apparent Opening Size (AOS), construction of a berm, or other filtration
systems.
4) Any runoff generated by dewatering discharge should be treated through construction of a
sediment trap if there is sufficient space. If space is limited other filtration methods will need to
be incorporated.
To prevent erosion after the project, the homeowner should limit the removal of native vegetation in the
area on and adjacent to the slope, although we understand that the slope is part of the adjacent property.
Vegetation should not be removed from slope areas without protection of exposed soils, and immediately
re-establishing permanent erosion control on the site. Water flow on the slope should be limited, and
roof, footing, and yard drains should not be directed toward, or onto the slope.

Structural Fill
KA No. 092-07039

Page 6 of 8
Best Management Practices (BMP's) should be followed when considering the suitability of native
material for use as structural fill. The on -site soils are considered moisture sensitive and will easily
degrade during rainy periods. The native soils are generally considered suitable for reuse as structural
fill, provided the soil is relatively free of organic material and debris, and it is within ± 2 percent of the
optimum moisture content. If the native soils are stockpiled for later use as structural fill, the stockpiles
should be covered to protect the soil from wet weather conditions. We recommend that a representative
of Krazan & Associates be on site during the excavation work to determine which soils are suitable for
structural fill.
It should not be taken for granted that the onsite soils may be used as the sole source for structural
fill (especially during winter construction activities). During wet weather conditions the soils with
higher silt and clay contents will be moisture sensitive, easily disturbed and most likely will not
meet compaction requirements. Furthermore, during the winter the native soils typically have
elevated natural moisture contents, which will limit the use of these materials as structural fill
without proper mitigation measures. The contractor should use Best Management Practices to
protect the soils during construction activities and be familiar with wet weather and wintertime
soil work. An allowance for importing structural rill should be incorporated into the construction
cost of the project (for wintertime construction this may be as high as 100 percent import).
Imported structural fill material should consist of well -graded gravel or a sand and gravel mixture with a
maximum grain size of 11/2 inches and less than 5 percent fines (material passing the U.S. Standard No.
200 Sieve). Angular crushed rock (clean — no fines) as well as control density fill (CDF) or lean mix
concrete may also be used as structural fill. All structural fill material should be submitted for approval
to the geotechnical engineer at least 48 hours prior to delivery to the site.
Fill soils should be placed in horizontal lifts not exceeding 8 inches loose thickness, moisture -
conditioned as necessary, (moisture content of soil shall not vary by more than ±2 percent of optimum
moisture) and the material should be compacted to at least 95 percent of the maximum dry density based
on ASTM Test Method D1557. In place density tests should be performed on all structural fill to verify
proper moisture content and adequate compaction. Additional lifts should not be placed if the previous
lift did not meet the compaction requirements or if soil conditions are not considered stable.
LIMITATIONS
Geotechnical engineering is one of the newest divisions of Civil Engineering. This branch of Civil
Engineering is constantly improving as new technologies and understanding of earth sciences improves.
Although your site was analyzed using the most appropriate current techniques and methods,
undoubtedly there will be substantial future improvements in this branch of engineering. In addition to
improvements in the field of geotechnical engineering, physical changes in the site either due to
excavation or fill placement, new agency regulations or possible changes in the proposed structure after
the time of completion of the soils report may require the soils report to be professionally reviewed. In
light of this, the owner should be aware that there is a practical limit to the usefulness of this report

without critical review. Although the time limit for this review is strictly arbitrary, it is suggested that
two years be considered a reasonable time for the usefulness of this report.
Foundation and earthwork construction is characterized by the presence of a calculated risk that soil and
groundwater conditions have been fully revealed by the original foundation investigation. This risk is
derived from the practical necessity of basing interpretations and design conclusions on limited sampling
of the earth. Our report, design conclusions and interpretations should not be construed as a warranty of
the subsurface conditions. Actual subsurface conditions may differ, sometimes significantly, from those
indicated in this report. The recommendations made in this report are based on the assumption that soil
conditions do not vary significantly from those disclosed during our field investigation. The findings and
conclusions of this report can be affected by the passage of time, such as seasonal weather conditions,
manmade influences, such as construction on or adjacent to the site, natural events such as earthquakes,
slope instability, flooding, or groundwater fluctuations. If any variations or undesirable conditions are
encountered during construction, the geotechnical engineer should be notified so that supplemental
recommendations can be made.
The conclusions of this report are based on the information provided regarding the proposed
construction. If the proposed construction is relocated or redesigned, the conclusions in this report may
not be valid. The geotechnical engineer should be notified of any changes so that the recommendations
can be reviewed and reevaluated.
Misinterpretations of this report by other design team members can result in project delays and cost
overruns. These risks can be reduced by having Krazan & Associates, Inc. involved with the design
teams meetings and discussions after submitting the report. Krazan & Associates, Inc. should also be
retained for reviewing pertinent elements of the design team's plans and specifications. Contractors can
also misinterpret this report. To reduce this, risk Krazan & Associates. Inc. should participate in pre -bid
and preconstruction meetings, and provide construction observations during the site work.
This report is a geotechnical engineering investigation with the purpose of evaluating the soil conditions
in terms of foundation design. The scope of our services did not include any environmental site
assessment for the presence or absence of hazardous and/or toxic materials in the soil, groundwater or
atmosphere, or the presence of wetlands. Any statements, or absence of statements, in this report or on
any exploration log regarding odors, unusual or suspicious items, or conditions observed are strictly for
descriptive purposes and are not intended to convey engineering judgment regarding potential hazardous
and/or toxic assessments.
The geotechnical information presented herein is based upon professional interpretation utilizing
standard engineering practices and a degree of conservatism deemed proper for this project. It is not
warranted that such information and interpretation cannot be superseded by future geotechnical
developments. We emphasize that this report is valid for this project as outlined above, and should not
be used for any other site. Our report is prepared for the exclusive use of our client. No other party may
rely on the product of our services unless we agree in advance to such reliance in writing.
