Page 2
Development plans are to construct one woo6-frame single-family residence with a
driveway. Site re-garding of exterior grades will be minor.
Access to the new residence will be from a driveway off of 92ns Avenue West The
new home will have a lower Rnish floor near existing grades.
3.0 EXISTING CONDITIONS
3.1 Site Surface Description
The community where the lot is located is an older established neighborhood along
the Edmonds Way Corridor from Interstate 5 to downtown Edmonds. The general
vicinity of the site is shown on the Vicinity Map (Plate 2).
It appears the property has not been developed in the past. There are a number of
large evergreen trees and forest shrubs on the site.
The building site is relatively level while the ground between the new residence and
92nd Avenue slopes down to the cast with a gentle gradient.
3.2 Geologic History
Geographically, this part of Edmonds ties within the Puget Lowland, an elongate
structural and topographic basin between the Olympic Mountains and Vie Cascade
Mountains. The entire area has been glaciated repeatedly during the past 2 million
years by coalescing glaciers that advanced southward from the north. The present

landscape was molded by cyclic g facial scouring and deposition (as the glaciers
retreated and advanced), and later modified by landslIdIng, faults, folding, erosion,
and man's activities.
This part of Edmonds generally sits atop a complex and incomplete succession of
interleaved glacial and non -glacial deposits overlying an irregular bedrock surface.
The glacial and non -glacial deposits vary laterally in both texture and thickness, and
may contain local uncomformities.
4.0 FIELD EXPLORATIONS
Three test pits were excavated on the site with a small track -mounted backhoe at
the approximate locations shown on the Site Plan, Plate 3. The pits were excavated
to a maximum depth of 3.5 feet below existing grades.
The test pits werc, observed, logged and sampled by the undersigned engineer
during excavation.
5.0 LABORATORY TESTING
Collected soil samples were reviewed in our offices and selected soil samples were
subjected to laboratory testing by a subcontract soils laboratory.
All soil testing for this project was conducted in substantial accordance with the
standards and methodologies prescribed in Volume 4.08 of the ASTM Standards.
For this project, two moisture content tests JASTM D-2216), which indicate the
percent moisture of the sample relative to the total dry weight of the soil and Grain

SlZe Distribution Tests (otherwise known as Sieve Gradation Tests) (ASTM D-422)
were conducted.
Results of these tests were used to classify the soil according to ASTM D-2487 and to
verify the field logs, which were then updated, as appropriate.
6.0 SUBSURFACE DESCRIPTION
The final Test Pit Logs attached to this report are our interpretations of the field data
and tMe laboratory tests. The stratification lines on the logs represent approximate
boundaries between soil types at the exploration locations. In actualjty� the
transition may be gradual. The relative densities and moisture descriptions on the
Test Pit Logs are interpretive descriptions based on observed conditions during
excavation.
The data described above and in previous sections was used to prepare an overall
description of the subsurface soil conditions underlying the property. Although
there may very well be variations from the following, we expect the subsurface soil
dcscription below to apply to much of the site:
The site is generally overlain with six inches of loose organic — rich
sandy soil or forest duff. Underlying this 5urficlal cover. is a rrlecllurr�-
dense gravelly silty sand with occasional cobbles. At 2 1/2to 3.0 feet
below grades, the test pits encountered very dense gravelly silty sand
glacial till. Groundwater was not noted during excavation, but we
do expect water to flow at the Interface between the surficial
medium -dense gravelly silty sand and the underlying glacial till
during rainy weather.

7.0 DISCUSSION &RECOMMENDATIONS
7.1 GENERAL
1) The proposed residential structure appears feasible to construct on this site
provided the recommendations contained in this report are incorporated into the
design.
2j Shallow foundations are suitable for this site.
31 All driveway and roof c1rainage should be captured and channeled to a properly
engineered discharge facility.

4) This project could be successfully constructed during the wet winter months
provided adequate erosion control is installed and maintained.
7.2 FOUNDATIONS
The proposed new structure may be founded on conventional continuous and
spread footings hearing on the native medium -dense to very dense gravelly silty
sand underlying the organic - rich topsoils. Minimum footing embedment should
be 18 inches below outside finish grades.
A bearing pressure of 2500 pounds per square foot may be assumed for footings
bearing as described above.
The design bearing pressure may be increased by one-third (1/3) to accommodate
short-term wind and seismic loads. To provide protection against shear fallure, we
recommend continuous and spread footings have a minimum width of sixteen
inches 116") and twenty-four inches 124"), respectively.
We estimate the foundations bearing on the native soils will settle approximately 1h
inch for every forty feet of continuous footing and between adjacent isolated
footings. differential settlements between building corners of 'A inch should be
anticipated in design.
Lateral Loads such as wind and seismic forces are resisted by ftiction between the
foundation elements and the bearing soils and the passive earth pressure against
the foundation walls. However, passive earth pressure should not be relied upon to
provide resistance unless the walls are poured directly against the existing soils or
structural RII Is compacted against the buried foundation walls. A coefficient of 0.45

may be used in design between the foundation elements and the supporting soils.
The passive resisiance of undisturbed native solls and compacted fill may be
assumed in design as an equivalent fluid having a density of 300 pounds per cubic
foot (pcf).
7.3 SEISMIC DESIGN
Seismic Design Category D2 should be used in design. As the project involves
construction of a residence, the provisions of the 2003 international Residential
Code should be applied to the structural design. All Ciry of Edmonds Title 19
Building Code requirements must be met in design.
7.4 STTE DRAINAGE
The site should be graded during construction so that surface water is directed
away from the excavation and away from the rock walls. Water should not be
allowed to pond where foundations, pavements or slabs are to be constructed.
Final site grades adjacent to the building should be sloped away from the bulldlng
for a minimum distance of five feet
We do recommend installing footing drains around the new buildings where the
lower finish floor, is to be excavated into the ground. Footing drains should consist
of a minimum fo ur-inch-dia meter slotted pipe that is bedded in, and covered with
minimum of six inches of drain rock or pea gravel. The top of the drain pipe should
be placed at least six inches below the elevation of the adjacent floor slab. A non-
woven geotextile fabric (Mirah 140N, Supac 4NP or other equivalent) should be

wrapped around the drain rock. The pipe should be sloped to drain, and may be
connected to the roof and surface water discharge pipes down -gradient and away
from the structure.
All drains (roof, surface water and footing drains) should discharge to an appropri-
ate discharge facility. If at all practical, gravity drainage is preferred over utilization
of a pump to achieve drainage.
7.5 EXCAVATIONS AND SLOPES
Temporary and permanent excavations and slopes for this project must meet all
applicable government safety regulations and standards. Temporary cuts to a
depth of four feet may be attempted vertical, but may not hold. Contractors
working in excavations and adjacent to slopes should use caution at all times as
sudden caving of side Slopes 15 P0551ble.
Permanent cut and fill slopes which are not otherwise reinforced should not exceed
21 (Horizonral:Vertical).
7.6 FLOOR SLAB SUBGRADE
Floor slabs, such as in the garage area, 5houfd be underlain with a minimum of six
inches of pea gravel, clean sand or crushed rock that is placed atop native
competent unyielding soils.

7.7 EARTHWORK AND sTRUCTURAL FILL
Site work should begin by stripping any deleterious material from the site. St . ripped
materials may have to be removed from the property.
Structural fill is defined as any fill placed below structures, including slabs. where the
fill soils need to support loads without unacceptable deflections or shearing,
Structural fill should be placed above unyielding subgrade soils In maximum eight -
inch -thick lifts and compacted to a minimum of 95% of Modified Proctor JASTM 0-
1557). Soil is typically difficult to place and compact as stiructural fill if the moisture
content at the tirne of compaction is more or less than 3% from the Optimum
Moisture Content. During wet weather or under wet conditions, structural fill
should consist of a granular soil having less than five percent slit or clay (measured
relative to that portion which passes a 3/4 inch sieve). During dry weather, water
may have to be added to the soil to achieve the required density.
7.8 WET WEATHER CCNSIDERATIONS
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 any fill piles will have to be protected with plastic.
2) It may be difficult to impossible to compact excavated soils.
3) Additional site visits will be required by this office to meet Ciry of Edmonds
requirements, evaluate conditions, confer with the contractor, and make
remedial recommendations.
4) Costs of maintaining the sire and adjacent streets/properties will increase.
5) Standard erosion control measures will be necessary.

as no study can completely quantify subsurface soil condition under a property with limited
explorations are Isolated locations. The owner should seriously consider any recommendations
for additional work contained in this report, as It Is our professional opinion that this additional
work is necessary to augment andlor fulfill project plans and site specific requirements.
This report is an Informational document and is not to be used for Contractual purposes. Any
interpretation of subsurface conditions in this report Including test logs and/or text discussions
are based upon our testing, observations, analysis. experience. and/orludgment. There is no
warranty that the described subsurface conditions, other than that which occurred at the exact
locations tested at the time of fieldwork was conducted by this firm. Groundwater levels can
be especially sensitive to seasonal changes. This firm is not responsible for interpretations
others may make using this report.
The Plain -English Exposition Sections of our report are simplified text discussions for lay readers,
and are nor supplemental additional information to be Used in design.
The conclusions and recommendations in this report assume that the field tests that were
conduction accurately represent subsurface conditions of the site. If, during construction,

driveway. Site r�garcling of exterior grades will be minor.
Access to the new residence will be from a driveway off of 92ns Avenue West. The
new home will h! ave a lower finish floor near existing grades.

3.0 EXISTIN' IONS
3.1 SiteSurf i ace Description
The community where the lot is located is an older established neighborhood along
the Edmonds Wpy Corridor from Interstate 5 to downtown Edmonds. The general
vicinity of the sit,e is shown on the Vicinity Map (Plate 2).
It appears the peloperty has not been developed in the past. There are a number of
large evergreen �trees and forest shrubs on the site.
The building sit6 is relatively level while the ground between the new residence and
92nd Avenue slopes down to the east with a gentle . gradient.
3.2 Geologic History
Geographically, this part of Edmonds lies within the Puget Lowland, an elongate
structural and topographic basin between the Olympic Mountains and the Cascade
Mountains. The� entire area has been glaciated repeatedly during the past 2 million
years by coalescing glaciers that advanced southward from the north. The present

and man's activities.
This part of Edmonds generally sits atop a complex and incomplete succession of
,iial and non -glacial deposits overlying an irregular bedrock surface.
interleaved glac I
The glacial and 'non -glacial deposits vary laterally in both texture and thickness, and
may contain local uncomformities.
4.0 FIELD EXPLORATIONS
Three test pits v�ere excavated on the site with a small track -mounted backhoe at
the approximat� locations shown on the Site Plan, Plate 3. The pits were excavated
to a maximum depth of 3.5 feet below existing grades.
The test pits we're observed, logged and sampled by the undersigned engineer
I
during excavation.
5.0 LABORATORY TESTING
Collected soil sa'mples were reviewed in our offices and selected soil samples were
subjected to laboratory testing by a subcontract soils laboratory.
I
All soil testing f6r this project was conducted in substantial accordance with the
standards and methodologies prescribed in Volume 4.08 of the ASTM Standards.
For this project,i two moisture content tests (ASTM D-2216), which indicate the
percent moistuele of the sample relative to the total dry weight of'the soil and Grain

ION & RECOMMENDATIONS
7.1 GENERAL
I
1) The proposed, residential structure appears feasible to construct on this site
provided the recommendations contained in this report are incorporated into the
design.
1
2) Shallow foundations are suitable for this site.
3) All driveway and roof drainage should be captured and channeled to a properly
engineered disc arge facility.
GROUND ENG11,\JEERING INC. Job Number 60601
June 19, 2006 Page 6
4) This project qould be successfully constructed during the wet winter months
provided adequ,bte erosion control is installed and maintained.
7.2 FOUNDATIONS
I
The proposed new structure may be founded on conventional continuous and
spread footings bearing on the native medium -dense to very dense gravelly silty
sand underlying the organic - rich topsoils. Minimum footing embedment should
be 18 inches below outside finish grades.
A bearing pressure of 2500 pounds per square foot may be assumed for footings
bearing as clescr�jibecl above.
The design bearing pressure may be increased by one-third (1/3) to accommodate
short-term wind and seismic loads. To provide protection against shear failure, we
recommend con' tinuous and spread footings have a minimum width of sixteen
I
inches (16") and twenty-four inches (24"), respectively.
We estimate the foundations bearing on the native soils will settle approximately 112
inch for every forty feet of continuous footing and between adjacent isolated
footings. differential settlements between building corners of 1/2 inch should be
anticipated in cl�sign.
Lateral Loads su I ch as wind and seismic forces are resisted by friction between the
foundation elel I 'ents and the bearing soils and the passive earth pressure against
the foundation walls. However, passive earth pressure should not be relied upon to
provide resistan ce unless the walls.are poured directly against the existing soils or
structural fill is compacted against the buried foundation walls. A coefficient of 0.45
1
GROUND ENGINEERING INC. Job Number 60601
June 19, 2006 1 Page 7
may be used in design between the foundation elements and the supporting soils.
The passive resisiance of undisturbed native soils and compacted fill may be
I
assumed in design as an equivalent fluid having a density of 300 pounds per cubic
foot (pcf).
7.3 SEISMIC DESIGN
Seismic Design (2,ategory D2 should be used in design. As the project involves
construction of a residence, the provisions of the 2003 International Residential
Code should be 'applied to the structural design. All City of Edmonds Title 19
1
Building Code r quirements must be met in design.
7.4 SITE DRAINAGE
The site should 6e graded during construction so that surface water is directed
away from the excavation and away from the rock walls. Water should not be
allowed to pond where foundations, pavements or slabs are to be constructed.
Final site grades ladjacent to the building should be sloped away from the building
for a minimum distance of five feet.
We do recommend installing footing drains around the new buildings where the
lower finish floo Is to be excavated into the ground. Footing drains should consist
of a minimum four-inch-cliameter slotted pipe that is bedded in, and covered with
minimum of six i I nches of drain rock or pea gravel. The top of the drain pipe should
be placed at leas I t six inches below the elevation of the adjacent floor slab. A non-
woven geotextilO fabric (Mirafi 140N, Supac 4NP or other equivalent) should be
GROUND ENGIN�EERING INC. Job Number 60601
June 19, 2006 1 Page 8
wrapped around
the drain rock. The pipe should be sloped to drain, and may be
connected to thel roof and surface water discharge pipes down -gradient and away
from the structu
All drains (roof, sOrface water and footing drains) should discharge to an appropri-
ate discharge facility. If at all practical, gravity drainage is preferred over utilization
of a pump to achieve drainage.
7.5 EXCAVATIONS AND SLOPES
Temporary and Oermanent excavations and slopes for this project must meet all
applicable gover n�ment safety regulations and standards. Temporary cuts to a
depth of four fee I t may be attempted vertical, but may not hold. Contractors
working in excavations and adjacent to slopes should use caution at all times as
sudden caving of side slopes is possible.
Permanent cut and fill slopes which are not otherwise reinforced should not exceed
2:1 (Horizon ta 1: Verti ca 1).
7.6 FLUUK SLAB SUBGRADE
I
Floor slabs, such as in the garage area, should be underlain with a minimum of six
inches of pea gravel, clean sand or crushed rock that is placed atop native
competent unyi Iding soils.
GROUND ENGINEERING INC. Job Number 60601
June 19, 2006 1 Page 9
7.7 EARTHWORK AND STRUCTURAL FILL
Site work should begin by stripping any deleterious material from the site. Stripped
materials may have to be removed from the property.
Structural fill is defined as any fill placed below structures, including slabs, where the
fill soils need to support loads without unacceptable deflections or shearing.
Structural fill sh6luld be placed above unyielding subgrade soils in maximum eight -
inch -thick lifts and compacted to a minimum of 95% of Modified Proctor (ASTM D-
1557). Soil is ty�ically difficult to place and compact as structural fill if the moisture
content at the time of compaction is more or less than 3% from the Optimum
Moisture Content. During wet weather or under wet conditions, structural fill
should consist o I f a granular soil having less than five percent silt or clay (measured
relative to that portion which passes a 3/4 inch sieve). During dry weather, water
may have to be added to the soil to achieve the required density.
7.8 WET WEATHER CONSIDERATIONS
If the site is developed during extended periods of wet weather or in the winter, the
following are ai4 I ticipated additional costs and changes which should be anticipated:
1) Excav alted slopes and any fill piles will have to be protected with plastic.
2) It may; be difficult to impossible to compact excavated soils.
3) Additional site visits will be required by this office to meet City of Edmonds
requirements, evaluate conditions, confer with the contractor, and make
remedial recommendations.
4) Costs of maintaining the site and adjacent streets/ p roperti es will increase.
5) Standard erosion control measures will be necessary.

A.2 PLAIN ENGLISH SUMMARY OF SECTION 7.0
The previous seettons of the report describe in detail our engineering conclusions
and recommendations.
Section 7. / - 7.8 6asical�v states that the project can be built using the standard
design parameters as ouffined In the report.
8.0 QUALITY CONTROL AND CLOSURE
This office should also be retained to provide geotechnical engineering consultation
I
and observation I services during construction. This will allow us to: 1) Confirm that
the design conforms to encountered subsurface conditions; 2) Confirm that
subsurface soils elxposed during excavation and drilling are consistent with those
anticipated; 3) Evaluate whether earthwork, drilling, subgrade preparation, and
I
subsurface drainage installation 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
-site safety or dimensional
or the work, nor' will we be responsible for providing on
measurements.

PLATE I
This report for Job No'. 60601 was prepared in accordance with local, generally accepted
engineering princip18, practices, and standards. No warranty is expressed or implied.
The findings and recommendations in this report are based upon the limited services which
you authorized. Geotechnical engineering requires the application of professional judgment,
as no study can comp!etely quantify subsurface soil condition under a property with limited
explorations are isolated locations. The owner should seriously consider any recommendations
for additional work contained in this report, as it is our professional opinion that this additional
work is necessary to alugment and/or fulfill project plans and site specific requirements.
This report is an informational document, and is not to be used for contractual purposes. Any
interpretation of subs ulrface conditions in this report, including test logs and/or text discussions
are based upon our testing, observations, analysis, experience, and/orjudgment. There is no
warranty that the described subsurface conditions, other than that which occurred at the exact
locations tested at the I time of fieldwork was conducted by this firm. Groundwater levels can
be especially sensitive,ito seasonal changes. This firm is not responsible for interpretations
others may make using this report.
The Plain-Englis, , Exposition Sections of our report are simplified text discussions for lay readers,
and are not supplemental additional information to be used in design.
The conclusions and recommendations in this report assume that the field tests that were
conduction accurately represent subsurface conditions of the site. If, during construction,
significantly different conditions are encountered from those described herein, 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 report submittal and the start of work on the
site, our firm shold be:retained to review and verify site conditions before site work begins.
Unanticipated soil conditions are commonly encountered during excavation and construction,
and simply cannot be i fully explored 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.
Ground Engineering Inc., cannot be held 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 intencle� to direct the contractor's methods, techniques, sequences, or
procedures, except as may be speciflcally described in the report. This firm will not be
responsible for any construction activity or site safety, nor are we responsible if others attempt
to apply this report to other sites.

RE: 23214 — 92 Ave W, Permit BLD20060661, Driveway Slope Exceeding 14%
Dear Mr. Johnson,
This is in response to your email dated October 30, 2007 requesting approval to exceed
the maximum allowed driveway slope of 14%. Review of prior inspections show a close
cooperation with city staff in regards to additional grading and overall driveway design in
the attempt to achieve a slope under 14% over the entire length of your driveway, which
clearly indicates a good faith effort on your part. Actual field conditions in this case
differed from the theoretical to the extent that, although a 14% slope has largely been
achieved, portions of the driveway approach 17%. City staff also notes these portions are
also sloped to ensure proper drainage of the driveway, and changing it can negatively
impact site drainage.
Your request to exceed a driveway slope of 14%, but not more than 20% is therefore
approved.
