Dear Mr. Ebel:
DEC 14
Job Number 8110
December 9, 1998
We are pleased to present the Geotechnical Engineering Report for the proposed new
residential structure to be constructed at 21010 Summit Lane in Edmonds, Washington.
The purposes of our work were to professionally evaluate subsurface soil and
groundwater conditions, recommend general procedures for the grading and underslab
treatment in the building areas, and recommend bearing capacities for shallow wall
footings, The scope of our services included:
1) Logging and sampling two test pits excavated to a maximum depth of 5.75
feet below existing grades. The test pits were located in a manner to provide
broad coverage of the proposed building sites. The test pits were excavated
with a rubber -tired backhoe and logged by the undersigned professional
engineer. Selected samples were taken of subsurface soils.
2) Reviewing collected soil samples in our office, and assigning appropriate
laboratory tests consisting of moisture contents and sieve gradation tests. At
the conclusion of the testing program, laboratory results were analyzed and
compared with field notes and logs.
3) Preparation of this preliminary summary report in accordance with our
understanding of project requirements and generally recognized local
geotechnical engineering practices. No other warranty is expressed or
implied. Plate 1, attached, provides the guidelines in the use of this report.
Prpiect lZnderstandira
This office was not provided with a site plan which documented site conditions including
.. . 11 '__ a___

your office.

We anticipate the new structure will be a wood -frame and multiple storied with possibly
a daylight basement. We anticipate finish grades will remain near existing grades.
fteral Site Conditions — SudkL
The proposed new structure will be constructed on the vacant lot at 21010 Summit Lane
in Edmonds, Washington, The attached Vicinity Map, Plate 2, shows the general vicinity
of the site.
At the time of our fieldwork, the proposed building site was covered with grass and
shrubs.
Subsurface Emigration and Description:
Two test pits were excavated with a rubber -tired backhoe to a maximum depth of 5.75
feet below existing grades. The test pits were logged and sampled by the undersigned
engineer. The test pit logs are attached to this report. Recovered soil samples were
subjected to moisture content and sieve gradation tesis. Test results and field density
information ate summarized on the test pit logs and attached plate. Although there may
very well be some variation in the subsurface and/or conditions may not be readily
apparent from the ground surface, we expect the following subsurface interpretation will
be essentially correct:
The property is generally overlain with organic -rich sandy topsoil and fill.
Underlying the fill is a brown loose to medium -dense gravelly silty sand which
becomes gray and very dense at about 4.0 to 5.5 feet below existing grades. The
test pits terminated in this dense to very dense layer, No seeping groundwater
was noted during logging of the test pits.
The final test pit logs attached to this report present our interpretation of the field data
and laboratory tests. The stratification lines on the togs represent approximate
boundaries between soil types at the exploration location. In actuality, the transition way
be gradual. The relative densities and moisture descriptions on the logs are interpretive

Conclusions and RecommIndations
General:
Job Number 8009
Page 3
The following general geotechnical conclusions can be drawn from our field and
laboratory test data:
1) The native dense to very dense sandy soils at about four to five feet below
existing grades can provide adequate bearing to the structure. A bearing
pressure of 3500 pounds per square foot (psf) can be utilized in design.
2) We recommend footing drains for all sides of the structure, Positive drainage
to an appropriate drainage structure is recommended.
3) Soils with a high percentage of silt and/or clay (>15%) are moisture sensitive
and difficult to impossible to utilize as structural fill is the soil is more than
two to three percent wetter or drier than the optimum moisture content at the
time of compaction. The soils at this site are silty, and are moisture sensitive.
FgUndations:
The proposed new structure may be supported on conventional continuous and spread
footings bearing on the dense to very -dense gravelly silty sandy soils at about four to five
feet below existing grades. Alternatively, the footings may bear on the compacted
structural fill built up from competent dense to hard native soils.
All footings should bear at a minimum depth of L5 feet below existing grades. A bearing
pressure of three thousand five hundred (3,500) psf may be assumed for footings bearing
directly on the dense to very dense native sandy soils. Footings bearing on compacted
structural fill should be designed for a maximum bearing pressure of two thousand
(2,000) psf The design bearing pressure may be increased by one-third to accommodate
short term wind and seismic loads.
To provide protection against shear failure, we recommend continuous and spread
footings have minimum widths of sixteen (16) inches and twenty-fOur (24) inches,
respectively.
Structural fill or crushed rock that is placed under footings should extend out beyond the
edges of the footings a minimum distance equal to one-half the fill depth. For example, if
two feet of structural fill was placed under a sixteen -inch -wide footing, the total
minimum width of the fill (and therefore the footing excavation) would be forty inches.

Page 4
We estimate that footings bearing on the dense to very dense native sandy soils or on
compacted structural fill will settle approximately one-half (1/2) inch between building
comers or for every fifty feet of continuous footing distance.
Lateral loads such as wind and seismic forces are accommodated by friction between the
foundation elements and the bearing soils and by,passive earth pressure against the
foundations. However, passive earth pressure is only available if compacted structural
fill is used to backfill against the foundations, or the foundations are poured against the
existing soil. The passive resistance of undisturbed native soil and properly compacted
structural fill may be assumed to be an equivalent fluid pressure of three hundred fifty
(350) pounds per cubic foot (pcf).
Seismic Deg=
The site is classified as Seismic Zone 3 by the Uniform Building Code. We recommend
the designer utilize site soil coefficientSDin their analysis.
Site Drainawe:
The site should be graded during construction so that surface water is directed away from
any excavation. Water should not be allowed to pond where foundations, pavements, or
slabs are to be constructed.
Final site grades adjacent to the buildings should be sloped away from the structure for a
minimum distance of ten feet. Roof and surface water drains should discharge to an
appropriate facility.
Footing drains are required, and should consist of a slotted four -inch -diameter PVC pipe
bedded in, and covered with a minimum of six inches of drain rock. The invert of the
pipe should be placed at the elevation of the footings. A non -woven geotextile fabric
(Mirafi. 140N, Supac 4NP, or other equivalent) should be wrapped around the outside of
the drain rock. The PVC pipe should be sloped to drain, and may be connected to the
roof and surface water discharge pipe down -gradient and away from the structure, The
pipes should discharge to an appropriate discharge facility.

Excavations and Slopes:
Job Number 8009
Page 5
Temporary and permanent excavation and slopes for this project must meet all applicable
government safety regulations. Temporary cuts to a depth of four feet may be attempted
vertical, although they will probably not hold. Excavation slopes greater than four feet in
depth should be cut no steeper than 1:1 (Horizontal: Vertical). Flatter slopes may be
required depending upon location variations in soils conditions and whether there is
groundwater present. Contractors working in excavations should use caution at all times.
Sudden caving of the side slopes is possible.
Permanent cut and fill slopes which are not otherwise reinforced should not exceed 2:1
(H*V)-
General Egghwork and Structural Fills
Site construction should begin by stripping and clearing' the property of all fill,
vegetation, organic -rich topsoil, and any other deleterious material. Stripped materials
may have to be removed from the site. Groundwater seepage was not noted during our
fieldwork. Nevertheless, the contractor should anticipate, and be prepared to
accommodate moderate seepage into even shallow excavations.
Structural fill is defined as any fill placed beloW structure, including stabs, where the fill
soils would need to support loads without unacceptable deflections or shearing.
Structural fill should be placed above unyielding native site soils in maximum eight -inch -
thick loose lifts and compacted to a minimum of 95% of Modified Proctor (ASTM
D1557).
Soil is typically difficult to place and compact as structural fill if more than three percent
from the optimum moisture content at the time of compaction. During wet weather or
under wet conditions, structural fill should consist of a granular soil having less than five
percent silt or clay (measured on that portion which passes the %-inch sieve). ]During dry
weather, water may have to be added to the soil to achieve the required soil density.

Wet Weather QonstDASaion:
Job Number 8009
Page 6
If the site is developed during extended periods of wet weather or in the winter, the
following are anticipated additional costs and changes which should be anticipated:
1) Excavated slopes and fill piles will have to be protected with plastic.
2) Most if not all of the excavated soils will be unusable as structural fill.
3) Foundation excavations will required over -excavation on the order of six
inches to one foot), and replacement with crushed rock.
4) Numerous site visits will be required by this office to evaluate soil conditions,
confer with the contractor, and make remedial recommendations.
5) Costs of maintaining the site and cleaning adjacent streets/property will
increase.
6) Construction access road reinforcement may be required, This may require
quarry spalls, geotextile fabric, lime or cement addition, or some combination
of these methods.

It is recommended we be retained to review the final development plans to verify site
specific subsurface requirements are met and our recommendations have been accurately
interpreted in the plans.
It is also recommended that we be retained to provide professional geotechnical
consultation and observation services during design and construction. This allows us to:
1) Confirm that design conforms to specific subsurface requirements; 2) Confirm that
subsurface soils conditions exposed during construction are consistent with those
indicated by this report; 3) Evaluate whether earthwork and foundation construction
activities conform to the intent of the contract specifications and plans; and, 4) Provide
recommendations for design changes in the event of changed conditions, While on the
site during construction, we will not direct or supervise the contractor or work, now will
we be responsible for providing on -site safety or dimensional measurements during
construction activities.

116 report for Job No. 8110 was prepared in accordance with local generally accepted
engineering principles and standards. No warranty is expressed or implied.
The findings and recommendations contained in this report are based upon the limited services
which you requested. Geotechnical engineering requires the application of professional
judgment, as no study can completely quantify subsuffice conditions. The owner should
seriously consider any recommendations for additional work contained in the report, as it is then
out professional opinion that this additional work is necessary to augment and/or fulfill site
specific requirements.
This report is an informational document, and is not to be used for contractual purposes. Any
interpretation of subsurface conditions in the repol including the test pit logs, and/or text
discussions are based upon our testing, analysis, experience, and jud1pnent. There is no warranty
that these subsurface interpretations represent subsurface conditions other than that which
occurred at the exact locations tested at the time the fieldwork was conducted by this firm.
Groundwater levels can be especially sensitive to seasonal changes. This firm is not responsible
for interpretations others make using this report.
Ile conclusions and recommendations in this report assume that the field tests that �vere
conducted accurately represent subsurface conditions of the site. If, during construction,
significantly different subsurface conditions are encountered from those described in this report,
our firm should be notified at once to review these conditions and revise out recommendations as
necessary. Also, if there is a significant lapse of time between this report submittal and the start
of work at the site, our Jrm should be allowed to review and verify site conditions.
Unanticipated soil conditions are commonly encountered during excavation and construction,
and simply cannot be fully anticipated by periodic soil and/or rock sampling at widely spaced
testing locations. The owner should be prepared to accommodate potential extra costs thrqugh
the development of a contingency fund.
This firm cannot be responsible for any deviation from the intent of this report including, but not
limited to the nature of the project, the construction timetable, and any construction methods
discussed in the report. The recommendations contained in the report are not intended to direct
the contractoes methods, techniques, sequences or procedures, except as may be specifically
described in the report. This firm will not be responsible for any construction activity on this
site, nor are we responsible if others attempt to apply this report to other sites.

ENVIRONMENTAL CHECKLIST
Purpose of Checklist.
The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the
environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all
proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide
information to hplp you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it
can be done) and to help the agency decide whether an EIS is required.
Instructionsfor Applicants:
This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this
checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer
the questions briefly, with the most precise information known, or give the best description you can.
You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer
the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or
if a question does not apply to your proposal, write "do not know",or does not apply". complete answers to the questions now may
avoid unnecessary delays later.
Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions
if you can. If you have problems, the governmental agencies can assist you. 0111,
The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of
land. Attach any additional information that will help describe your proposal or its environmental effects.'The agency to which you
submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if
there may be significant adverse impact.
Use of checklistfor nonprojectproposals:
Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." IN ADDITION,
complete the SUPPLENENTAL SHEET FOR NONPROJECT ACTIONS (part D).
For nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should be read as
nproposer, " and "affected geographic area," respectively.

Dear Mr. Ebel:
DEC 14 '191,48
Job Number 8110
December 9, 1998
We are pleased to present the Geotechnical Engineering Report for the proposed new
residential structure to be constructed at 2 10 10 Summit Lane in Edmonds, Washington.
The purposes of our work were to professionally evaluate subsurface soil and
groundwater conditions, recommend general procedures for the grading and underslab
treatment in the building areas, and recommend bearing capacities for shallow wall
footings. The scope of our services included:
1) Logging and sampling two test pits excavated to a maximum depth of 5.75
feet below existing grades. The test pits were located in a manner to provide
broad coverage of the proposed building sites. The test pits were excavated
with a rubber -tired backhoe and logged by the undersigned professional
engineer. Selected samples were taken of subsurface soils.
2) Reviewing collected soil samples in our office, and assigning 'appropriate
laboratory tests consisting of moisture contents and sieve gradation tests. At
the conclusion of the testing program, laboratory results were analyzed and
compared with field notes and logs.
3) Preparation of this preliminary summary report in accordance with our
understanding of project requirements and generally recognized local
geotechnical engineering practices, No other warranty is expressed or
implied, Plate 1, attached, provides the guidelines in the use of this report,
Project Understandings:
This office was not provided with a site plan which documented site conditions including
tppography. Our KnOWLeuge of this project is generally Limited t,
your office.

We anticipate the new structure will be a wood -frame and multiple storied with possibly
a daylight basement. We anticipate finish grades will remain near existing grades.
general Site Conditions — Suffa�L
The proposed new structure will be constructed on the vacant lot at 21010 Summit Lane
in Edmonds, Washington, The attached Vicinity Map, Plate 2, shows the general vicinity
of the site.
At the time of our fieldwork, the proposed building site was covered with grass and
shrubs.
Subsurface Exploration and Description:
Two test pits were excavated with a rubber -tired backhoe to a maximum depth of 5.75
feet below existing grades, The test pits Were logged and sampled by the undersigned
engineer. The test pit logs are attached to this report. Recovered soil samples were
subjected to moisture content and sieve gradation tests, Test results and field density
information are summarized on the test pit logs and attached plate, Although there may
very well be some variation in the subsurface and/or conditions may not be readily
apparent from the ground surface, we expect the following subsurface interpretation will
be essentially correct:
The property is generally overlain with organic�rich sandy topsoil and fill.
Underlying the fill is a brown loose to medium -dense gravelly silty sand which
becomes gray and very dense at about 4.0 to 5,5 feet below existing grades. The
test pits terminated in this dense to very dense layer, No seeping groundwater
was noted during logging of the test pits.
The final test pit logs attached to this report present our interpretation of the field data
and laboratory tests. The stratification lines on the logs represent approximate
boundaries between soil types at the exploration location. In actuality, the transition may
be gradual. The relative densities and moisture descriptions on the logs are interpretive
descriptions based on observed conditions during excavation, The logs should be
reviewed for specific subsurface information at each location tested.

Conclusions and Recommendation
Qgneral:
Job Number 8009
Page 3
The following general geotechnical conclusions can be drawn from our field and
laboratory test data:
1) The native dense to very dense sandy soils at about four to five feet below
existing grades can provide adequate bearing to the structure. A bearing
pressure of 3500 pounds per square foot (psf) can be utilized in design.
2) Werecommend footing drains for all sides of the structure, Positive drainage
to an appropriate drainage structure is recommended.
3) Soils with a high percentage of silt and/or clay (>15%) are moisture smitive
and difficult to impossible to utilize as structural fill is the soil is more than
two to three percent wetter or drier than the optimum moisture content at the
time of compaction. The soils at this site are silty, and are moisture sensitive.
FgUndations:
The proposed new structure may be supported on conventional continuous and spread
footings bearing on the dense to very -dense gravelly silty sandy soils at about four to five
feet below existing grades. Alternatively, the footings may bear on the compacted
structural fill built up from competent dense to hard native soils.
All footings should bear at a minimum depth of L5 feet below existing grades. A bearing
pressure of three thousand five hundred (3,500) psf may be assumed for footings bearing
directly on the dense to very dense native sandy soils. Footings bearing on compacted
structural fil) should be designed for a maximum bearing pressure of two thousand
(2,000) psf The design bearing pressure may be increased by one-third to accommodate
short term wind and seismic loads.
To provide protection against shear failure, we recommend continuous and spread
footings have minimum widths of sixteen (16) inches and twenty-four (24) inches,
respectively.
Structural fill or crushed rock that is placed under footings should extend out beyond the
edges of the footings a minimum distance equal to one-half the fill depth. For example, if
two feet of structural fill was placed under a sixteen -inch -wide footing, the total
minimum width of the fill (and therefore the footing excavation) would be forty inches.

We estimate that footings bearing on the dense to very dense native sandy soils or on
compacted structural fill will settle approximately one-half (1/2) inch between building
comers or for every fifty feet of continuous footing distance.
Lateral loads such as wind and seismic forces are accommodated by ftiction between the
foundation elements and the bearing soils and by passive earth pressure against the
foundations. However, passive earth pressure is only available if compacted Structural
fill is used to backfill against the foundations, or the foundations are poured against the
existing soil. The passive resistance of undisturbed native soil and properly compacted
structural fill may be assumed to be an equivalent fluid pressure of three hundred fifty
(350) pounds per cubic foot (pcf).
Seismic DegiM
The site is classified as Seismic Zone 3 by the Uniform Building Code. We recommend
the designer utilize site soil, coefficient SD in their analysis.
Site Drainage:
The site should be graded during construction so that surface water is directed away from
any excavation. Water should not be allowed to pond where foundations, pavements, or
stabs are to be constructed,
Final site grades adjacent to the buildings should be sloped away from the Structure for a
minimum distance of ten feet. Roof and surface water drains should discharge to an
appropriate facility.
Footing drains are required, and should consist of a slotted four -inch -diameter PVC pipe
bedded in, and covered with a minimum of six inches of drain rock. The invert of the
pipe should be placed at the elevation of the footings. A non -woven geotextile fabric
(Mirafl NON, Supac 4NP, or other equivalent) should be wrapped around the outside of
the drain rock, The PVC pipe should be sloped to drain, and may be connected to the
roof and surface water discharge pipe down -gradient and away from the structure. The
pipes should discharge to an appropriate discharge facility,

Excavations and Slopes:
Job Number 8009
Page 5
Temporary and permanent excavation and slopes for this project must meet all applicable
government safety regulations. Temporary cuts to a depth of four feet may be attempted
vertical, although they will probably not hold. Excavation slopes greater than four feet in
depth should be cut no steeper than 1: 1 (Horizontal; Vertical). Flatter slopes may be
required depending upon location variations in soils conditions and whether there is
groundwater present. Contractors working in excavations should use caution at a times.
Sudden caving of the side slopes is possible.
Permanent cut and fill slopes which are not otherwise reinforced should not exceed 2:1
(H,V)-
General Egghwork and Structural Fill!
Site construction should begin by stripping and clearing the property of all fill,
vegetation, organic-fich topsoil, and any other deleterious material. Stripped materials
may have to be removed from the site, Groundwater seepage was not noted during our
fieldwork. Nevertheless, the contractor should anticipate, and be prepared to
accommodate moderate seepage into even shallow excavations,
Structural fill is defined as any fill placed below structure, including slabs, where the fill
soils would need to support loads without unacceptable deflections or shearing,
Structural fill should be placed above unyielding native site soils in maximum eight -inch -
thick loose lifts and compacted to a minimum of 95% of Modified Proctor (ASTM
D1557).
Soil is typically difficult to place and compact as structural fill if more than three percent
from the optimum moisture content at the time of compaction. During wet weather or
under wet conditions, structural fill should consist of a granular soil having less than five
percent silt or clay (measured on that portion which passes the3/4-inch sieve). )During dry
weather, water may have to be added to the soil to achieve the required soil density.

If the site is developed during extended periods of wet weather or in the winter, the
following are anticipated additional costs and changes which should be anticipated:
1) Excavated slopes and fill piles will have to be protected with plastic.
2) Most, if not all of the excavated soils will be unusable as structural fill.
3) Foundation excavations will required over -excavation on the order of six
inches to one foot), and replacement with crushed rock,
4) Numerous site visits will be required by this office to evaluate soil conditions,
confer with the contractor, and make remedial recommendations.
5) Costs of maintaining the site and cleaning adjacent streets/property will
increase.
6) Construction access road reinforcement may be required. This may require
quarry spalls, geotextile fabric, lime or cement addition, or some combination
of these methods.
closurs:
It is recommended we be retained to review the final development plans to verify site
specific subsurface requirements are met and our recommendations have been accurately
interpreted in the plans.
It is also recommended that we be retained to provide professional geotechnical
consultation and observation services during design and construction. This allows us to:
1) Confirm that design conforms to specific subsurface requirements; 2) Confirm that
subsurface soils conditions exposed during construction are consistent with those
indicated by this report; 3) Evaluate whether earthwork and foundation construction
activities conform to the intent of the contract specifications and plans; and, 4) Provide
recommendations for design changes in the event of changed conditions, While on the
site during construction, we will not direct or supervise the contractor or work, now will
we be responsible for providing on -site safety or dimensional measurements during
construction activities.

This report for Job No. 8110 was prepared in accordance with local generally accepted
engineering principles and sundards. No warranty is expressed orimplied.
Ilie findings and recommendations contained in this report are based upon the limited services
which you requested. Geotcchnical engineering requires the application of professional
judgment, as no study can completely quantify subsurface conditions. The owner should
seriously consider any recommendations for additional work contained in the report, as it is then
out professional opinion that this additional work is necessary to augment and/or LIM site
specific requirements.
TIds report is an informational document, and is not to be used for contractual purposes. Any
interpretation of subsurface conditions in the repol including the test pit logs, and/or text
discussions are based upon our testing, analysis, experience, and judgment. There is no wa t
that these subsurface 'interpretations represent subsurface conditions other than that =
occurred at the exact locations tested at the time the fieldwork was conducted by this firm.
Groundwater levels can be especially sensitive to seasonal changes. This firm is not responsible
for interpretations others make using this report.
Ile conclusions and recommendations in this report assume that the field tests that were
conducted accurately represent subsurface conditions of the site. If, during construction,
significantly different subsurface conditions are encountered from those descTibed in this report.
our firm should be notified at once to review these conditions and revise our recommendations as
necessary. Also, if there is a significant lapse of time between this report submittal and the start
of work at the site, our firm should be allowed to review and verify site conditions.
Unanticipated soil conditions are conurionly encountered during excavation and construction,
and simply cannot be fully anticipated by periodic soil and/or rock sampling at widely spaced
testing locations. The owner should be prepared to accommodate potential extra costs through
the development of a contingency fund.
This firm cannot be responsible for any deviation frorn the intent of this report including, but not
Wnited to the nature of the project, the construction timetable, and any construction methods
discussed in the report. The recommendations contained in the report are not intended to direct
the contractor's methods, techniques, sequences or procedures, except as may be specifical1y
described in the report. This firm will not be responsible for any construction activity on this
site, nor are we responsible if others attempt to apply this report to other sites.
