Re: Geologic Hazard Opinions
Proposed Pham Residence

Federal Way, Washington
Permit No. o6-102492-oo-SF
RMP Project No. o6-154-01
Dear Ms. Cimmer,
Consulting
Engineer
Following our meeting yesterday when we discussed your requirements for a
geotechnical response to the four geologic hazards applicable to the Pham property. We
have evaluated this site with regard to the potential landslide, steep slope, seismic and
erosion hazards in accordance with the City Code Section 22-1286, and have the
following conclusions:
• Landslide Hazard — the site is underlain by dense Outwash deposits that are
considered stable and do not represent a landslide hazard; the site slopes are in
excess of 15 % as determined by survey, and the soils are permeable due to the
presence of silty sands and gravel; they do not overlie impervious sediments or
bedrock except at great depths below the site, and there is no evidence of
groundwater seepage or springs on the property; geologic mapping of this site
showed no evidence of mass wasting or previous landslide movement; there is no
stream activity or stream bank erosion or undercutting by wave action; this site is
not an alluvial fan and is not subject to inundation by debris flows or flooding;
stability analyses show that this property is grossly stable under static and
seismic conditions, and that there is no landslide hazard that exists on this site;
this site is not subject to rockfall, soil instability or failure during seismic activity.
• Erosion Hazard — there is no evidence to indicate that active erosion is occurring
on this site due to wind, rainfall, stream flow, frost action or other naturally
occurring activity; this property is not considered an erosion hazard;
• Seismic Hazard — our evaluation of this property shows that it is not subject to
ground movement or settlement resulting from moderate earthquake activity on
nearby fault zones; the site is underlain by dense granular Outwash soils and the
groundwater levels are well below the ground surface; liquefaction of the onsite

September 29, 2006
Ms. Kari Cimmer
Page 2
granular soils will not occur due to their relatively high density, and the lack of a
groundwater table that is required to induce liquefaction; as a result this site does
not qualify as a potential seismic hazard;
• Steep Slope — my review of the topographic plan for this property shows that the
house footprint does not fall on slope that is greater than 40%; at the top of the
slope there is extensive fill that was placed on this property as a result of the
grading and fill placement for 297th Street; this fill extends onto the Pham
property and ranges in depth from o.o feet (TP-3) to as much as 8.5 feet (TP-2) at
the locations shown on drawing No.1; a subsoil profile was developed to identify
the depths of fill and the original natural ground surface extending downslope
from 297th Street; this cross section shows that the original natural ground
surface was less than 40% as determined over a vertical io foot elevation
differential in accordance with City code requirements; these measurements were
extrapolated from the south property line at the street down to the north end of
the house using the depths of fill actually encountered in the field; slope
gradients ranged from 12.% along the east side of the house to 29.7% along the
west side; placement of the road fill has steepened the original slope conditions
considerably and should be taken into consideration when applying the steep
slope criteria to this site.
I trust that this response provides the required information in accordance with the City
Code Section 22-1286 regarding the existing favorable conditions relative to the GHA.

Dear Mr. and Mrs. Pham,
At the request of Ms. Cimmer at Federal Way I have reviewed the prior reports related
to the design and construction of your proposed residence at 410 SW 297th Street in
Federal Way. Ms. Cimmer has requested clarification of our conclusions regarding
constructability of your proposed residence on this property that is located within a
GHA as described in Division 4 of Chapter 22.
Our May 8th report concluded that the property was stable and will provide satisfactory
support for the proposed structure. A discussion on the erosion, landlside and seismic
hazards were provided in our July 27th report.
On the basis of our prior investigation and geotechnical review, the site is considered
buildable within this GHA area, and that the existing geologic hazards will not adversely
impact the proposed residence.

there is no landslide hazard that exists on this site;
• Erosion Hazard — there is no evidence to indicate that active erosion is occurring
on this site due to rainfall, stream flow or other naturally occurring activity; this
property is not considered an erosion hazard;
• Seismic Hazard — our evaluation of this property shows that it is not subject to
ground movement resulting from moderate earthquake activity on nearby fault
zones; the site is underlain by dense Outwash soils and the groundwater levels
are well below the ground surface; as a result this site does not qualify as a
potential seismic hazard;
• Steep Slope — my review of the topographic plan for this property shows that the
house footprint does not fall on slope that is greater than 40%; I measured the
critical site contours in the southwest corner of the property where there was an
expressed concern over slope steepness, and these contours do not exceed 40%;

l have a ground elevation right near the water meter at the SW property corner, which is the top of the
slope, and the elevation is 306.35. The distance from this top of slope point to the toe of slope at approx.
the 292 contour is 36.3 feet. It is very close to 40% but comes in just under at 39.53%. In fact it is so close
that depending on exactly where you take your measurements from you might get anywhere from 38% to
just over 40%. It is only this close right along the property line, if you come in about 10 feet from the line
the slope is closer to 38%, and towards the center of the lot the slope is about 37%. I would assume your
building setback along the property line is at least 5 feet, and if I measure the slope 5' east of the west
property line, starting from the south property line and measuring north, I calculate 38.05%, which would
be along the setback line.
Also, you mentioned the NW property corner. I've measured the slope in this area and calculate 27%. if
you connect the sewer stub to your house you should not encounter any slopes greater than 40%,
Please feel free to give me a call with any questions or concerns.

Re: Permit #06-102492-00-SF; LAND USE REVIEW
Pham; No Site Address, Federal Way
Dear Mr. and Mrs. Pham:
Analysis of all of the information you've submitted for review indicates that the proposed project
will occur on or within 25 feet of a geologically hazardous area (GHA). Therefore, unless you're
able to produce conclusive evidence to the contrary, in order to continue with the proposed
development of the new single-family residence at this site you'll need to proceed with an
environmental review. The following paragraphs outline the steps to take.
Per Federal Way City Code (FWCC) Section 22-1651, a preapplication meeting is required, unless
otherwise waived. Representatives from all City permit review divisions, as well as the fire
department and Lakehaven Utility District, will attend the meeting and will discuss their particular
requirements as they relate to your project. I have enclosed a master land use application and
Preapplication Conference handout, which is a checklist of the items you'll need to submit when
applying for the preapplication meeting. Please note there is a $410.50 nonrefundable fee for the
meeting and it takes approximately three to four weeks to get on the schedule from the time the
plans are submitted.
If you wish to request a waiver to the preapplication meeting, a letter must be submitted to Kathy
McClung, Director of Community Development Services. Her decision is based on your
responses to the criteria listed in FWCC Section 22-1653, "Exceptions," code section, which I've
enclosed for your use.
The benefit of the preapplication meeting to the homeowner who is developing his or her own
GHA-impacted property is that of being able to meet with experienced staff that has familiarity
with assisting homeowners and developers with the complexities of constructing on a challenging
site. Staff does visits to your site, as well as meets internally to work out any intradepartmental or
intra jurisdictional issues prior to meeting with you, with the goal of making every effort to
identify major issues to eliminate surprises during the City's review of the formal application.
The planner assigned to review this project will then follow up this preapplication meeting with
an instructional letter and handouts to assist you with the formal application for your
environmental review. I encourage you to take advantage of this meeting, if at all possible.

Van & Myle Pham

August 22, 2006
If you request and are granted the waiver of the preapplication meeting, you will need to proceed
with the formal submittal for your environmental review. Submittal requirements will be as
follows:
✓Master Land Use Application — one copy required — Completed and signed.
✓Waiver Letter — one copy required — A copy is acceptable, please keep your original.
✓Site Plan — eight copies required — The site plan prepared by Cascade Residential
Design, Inc., revision date 7-31-06, would work well for this part of the submittal. My
only aside on this is, based on the contours provided on the site plan; there appear to be
areas of 40 percent slopes missing from the survey, specifically in the southwest corner
of the property. If that could be revised prior to submittal, it would be helpful to staff
reviewing the project.
✓State Environmental Policy Act (SEPA) - eight copies required — Pursuant to FWCC
Section 18-143, the proposed project requires SEPA review (compliance) because the
work is proposed within an environmentally critical area. A completed environmental
checklist must be submitted to the City. The SEPA review requires an application fee of
$1,553.50. An environmental threshold determination on the proposed action will be
issued by the City and the determination will be distributed in accordance with City code
requirements.
✓Public Notice — one set of envelopes & one list required — With the application,
provide one set of stamped, addressed envelopes for property owners within 300 feet of
the subject site. Include the City of Federal Way return address on all envelopes. For our
records, provide a list of the property owners within 300 feet of the subject site, with
parcel number and address referenced. Also, provide a corresponding parcel map
showing the 300-foot radius from the subject site. A handout with procedures for
obtaining mailing labels is enclosed.
-'Geologically Hazardous Areas Development — four copies required - The subject
property is located within landslide hazard and steep slope hazard critical areas. FWCC
Chapter 22, Article XIV, Division 4, "Geologically Hazardous Areas (GHA)
Development' includes definitions of each of the geologically hazardous areas. In order
to construct the proposed residence and associated improvements, a soils report (and
construction plans), prepared by an engineer in the State of Washington, must be
prepared and provided to the City. The soils report must specifically address each of the
requirements identified in FWCC Section 22-1286(c)(1-4). You may submit the original
and supplemental reports prepared by Robert M. Pride, LLC, to satisfy this requirement;
however, be aware that the planner assigned to this project will likely require a revised
soils report.
✓GHA Letter — one copy required — In conjunction with the SEPA application and soils
report, provide a letter to Director of Community Development Services Kathy McClung
requesting intrusion into the geologically hazardous area. Upon submittal, the City will
assign an "AD" file number to the GHA intrusion request.
Permit#06-102492-00-SF Doc ID 37704
Van & Myle Pham
Page 3
August 22, 2006
Please note that the City does, not have a geotechnical engineer on staff to review the soils report;
however, we contract with a consulting firm that conducts geotechnical engineering review on
behalf of the City. The City's geotechnical review must be paid by the applicant and pre -funded
prior to conducting the review. Upon submittal of a soils report, the City will request a scope of
work and estimated cost of review of the soils report.
Given that my knowledge of the environmental review process is stronger in the zoning and
environmental code areas, it's quite likely I've missed items from Public Works Department,
Building Divisions, South King Fire and Rescue, and Lakehaven Utility District, things you
would be aware of if you attend a preapplication meeting. However, as long as you bring the
appropriate number of copies of the above -noted items and the $1,553.50 submittal fee, you
should have enough information to get your SEPA application "in the door," if you decide to
proceed on your own.
If you have any questions this letter or the environmental review process, please feel free to
contact me at 253-835-2629, or karic(a)ci offederalwa .com.

This report provides supplemental information on this geologic hazard. area (GHA) as
requested in the Federal Way letter dated June 23rd. Our responses are as follows:
1. Erosion Hazard — This site is susceptible to surficial erosion of the existing soils
under concentrated flow conditions. As previously mentioned a water line break
in the street caused severe erosion on thie lower portion of this site. Normal
rainfall would not cause erosion rills or gullies, and in our opinion the proposed
landscape improvements will reduce this potential even further. At the north end
of the site the slope grades become steeper that 4o%, but within the area of the
proposed building pad development the slope gradient is less than 40%.
2. Landslide Hazard — This property falls within the greater than 15% slope, and
portions of the property are greater than 40%. Despite the steepness of the
existing slopes, slope stability analysis shows that the factor of safety against
gross failure is greater than FS =1.5. Surficial stability under conditions of
saturation of the upper 3 to 4 feet is still in excess of 1.5 for the building pad area
that is situated at least 30 feet behind the top of the critical top of slope line.
Test pit excavations on this property did not encounter groundwater to a
maximum depth of 16.5 feet, and there was no evidence of seepage or springs on
the descending slope below the building pad area. Prior erosion and channeling
of the descending slope was caused by a water main break — not by loss of
strength of the soils from heavy rainfall or spring activity.
3. Seismic Hazards — Based on our research this property is susceptible to seismic
activity and strong ground motions. Earthquakes occur in the Puget Sound area
with great regularity and the majority of these earthquakes are small and usually
not noticeable. Large earthquakes do occur as evidenced by the -1949 (M7.2)

Olympia event, the 1965 (M6.5) Tacoma event, and the 2001 (M6.8) Nisqually
event. Normally the epicenter of these larger earthquakes is relatively deep below
the ground surface.
Generally there are four types of potential geologic hazards associated with large
seismic events: 1) ground rupture, 2) landslides, 3) liquefaction, and 4) ground
motion. The nearest known fault system is the Seattle fault zone located about
fifteen miles to the north. USGS continues to study this and other fault systems
in the Puget Sound region, and it has been determined that they are capable of
generating large earthquakes. Return periods for large earthquakes vary from
500 to more than l000 years. The long recurrence intervals for nearby fault
systems usually results in a low potential for ground rupture or landslide
movement over the life of the proposed residential structure.
Based on the subsurface soil and groundwater conditions encountered on this
and adjacent sites, the potential for liquefaction is considered low. As long as the
foundations are supported by the native Outwash deposits the structure will not
experience any excessive settlement from ground shaking. Structure setback
from the top of the 40% slope will provide adequate protection against lateral
slope displacements during a seismic event. In accordance with the 2003 IBC —
Table 1615.1.1 -- the subject site is defined as Class D.
4. Steep Slope Hazard — As discussed above the building pad area will be located on
the upper portion of the site — a majority of which has less than 40% slope
gradient. The daylight basement will extend into this slope with maximum cuts
on the order of eight feet below existing grade. Footings will extend through the
fill and bear in the dense Outwash deposits. The steep slope below the proposed
residence will not create a stability concern to the structure foundations.
All site excavation, foundation trenching and backfrll placement will occur upslope from
the 25 foot buffer zone extending back from the top of the steep slope. It is essential
that appropriate silt fencing and orange construction fencing be established at the start
of this project to insure that the onsite soils do not encroach into the buffer. It may be
necessary to install hay bales to control surface water runoff in addition to the silt
fencing for slope protection. Please call me if there are any questions.

Dear Mr. Pham,
This report provides additional information on this geologic hazard area (GHA) as
requested in the Federal Way letter dated June 23rd. Our responses are as follows:
1. Erosion Hazard — existing soils on this property consist primarily of silty sand
with gravel that are susceptible to erosion under concentrated flow conditions.
As previously mentioned a water line break in the street caused severe erosion on

gullies, and in our opinion the proposed landscape improvements will reduce this
potential even further. At the north end of the site the slope grades become
steeper that 40%, but within the area of the proposed building pad development
the slope gradient is less than 40%.
2. Landslide Hazard — this property falls within the greater than 15% slope, and
except for the lower portion of the site the major portion of the property is less
than 40%. Slope stability analysis shows that the factor of safety against gross
failure is greater than FS = 1.5. Surficial stability under conditions of saturation

RMP Project No. o6-154-01
Dear Mr. Pham,
RECEIVED
MAY 1 8 2006
CITY OF FEDERAL WAY
BUILDING DEPT.
This report presents the results of our geotechnical site evaluation for your proposed
residence to be constructed at 410 SW 29 7th Street in Federal Way. It is understood that
the residence will be a three story wood framed structure with a daylight basement at
the lower level.
The purpose of this report is to document the geologic soil profile under the property,
and to provide engineering recommendations for the design and construction of the
residence. A site plan and cross sections prepared by Cascade Residential Design and
previous exploratory test pits by ECI were used as references for this report.
Site Conditions
A total of five exploratory test pits were dug on the slope areas to develop a soil profile
under the proposed residence. Depths of these test pits ranged from io to x6 feet, and
their locations are shown on the attached Drawing No.1. In addition an engineering
geologist surveyed the entire slope extending from the street level down to the north
property line where a shallow drainage Swale exists. The upper portion of this drainage
swale has been covered with soil and wood debris from prior filling operations. It is
understood that a debris flow occurred on this property from inadequate drainage
control originating from,the street level adjacent to this site.
Most of the exploratory pits dug on the slope showed a thick layer of loose fill over
topsoil ranging from 5 tb to feet in depth. Below the sand -silt and debris fill were
medium dense to dense Dutwash deposits consisting of silty sand, sand and gravel.
These glacial deposits extended the full height of the north -facing slope on the property.
Groundwater seepage was not observed within the 4utwash sand and gravel formation.
Geologic reconnaissance mapping of the exposed slope showed no evidence of deep-

seated landsliding, erosion gullies or areas of shallow slope failures. The slope was
covered with native shrubs and mature trees without evidence of excessive creep of the
surficial soils on the slope.
Conclusions and Recommendations
General
On the basis of our geologic and geotechnical site evaluations, the property is considered
stable and will provide satisfactory support for the proposed residence. Stability
analyses were performed for the building site and they show that the building pad is
grossly stable from deep-seated sliding with a safety factor in excess of 1.5. The entire
footprint of the residence will be situated 30 feet behind the top of the critical slope a
area. In our opinion the residence can be supported on continuous bearing wall footings
that extend down through the fill and onto the dense Outwash deposits.
Temnorary Slope Excavations
Construction of the basement retaining wall will require temporary slopes to be cut into
the existing slope to depths ranging from 1 to 8 feet. It is recommended that they be cut
at a gradient no steeper than 1H:1V where soil fill is exposed and at 3H:2V in the debris
fill. All temporary cut slopes should be covered with plastic sheeting and tied down with
sandbags to protect the slopes from heavy rainfall.
Foundation Remmmendatims
For continuous bearing wall footings that will be supported on the medium dense to
dense Outwash sands, we recommend that they be designed for an allowable bearing
value of 2000 psf. This value maybe increased by 1/3 to account for temporary seismic
or wind loading. Settlement of these footings should not exceed one inch, and a
majority of this settlement will occur during construction of the residence. Resistance to
lateral forces can be provided be a passive value of 250 pcf where footings and basement
retaining walls are backfilled with compacted onsite granular fill.
Retaining Walls
Basement retaining walls will be constructed around the three sides of the residence to a
maximum height of about 12 feet. Design of cantilevered retaining walls should be
based on active earth pressures of 35 pcf and 50 pcf for level and sloping backfill
conditions, respectively. Resistance to lateral loads on these walls can be provided by a
passive pressure value of 250 pcf.

geofilter cloth should be accomplished at the base of all retaining walls and perimeter
foundation walls. These subdrains should be connected to a tightline for discharge to an
approved location.
Low landscape block walls may be constructed along the lower north side of the daylight
basement to extend the rear yard area. As long as these walls are less than four feet in Oaw,
height, they do not need to be permitted and can be constructed along with your future
landscape improvements.
Erosion Control
Construction of this residence may take place during the wet weather period starting in
October, and that will require additional measures to secure this site. Fortunately a
majority of the onsite soils are granular and will absorb most rainfall on the pad and
slope areas. Normal silt fencing will need to be installed around the lower perimeter of
the building pad area, and the access driveway entry should be protected with quarry
spalls. The silt fencing should be anchored at the base with onsite granular soils to act
as a filter for storm water runoff at the north end of the property. Any soil stockpiles
should be covered with plastic sheeting until they are either exported from the property,
or used as backfill around the foundation walls.
Summary
The conclusions and recommendations presented in this report are based on 1) our
interpretation and evaluation of soil conditions on the site, 2) confirmation of the actual
subsurface conditions encountered during construction, and 3) that sufficient
observation and testing will be provided during appropriate phases of the work.
Our findings and recommendations of this report were prepared in accordance with
generally accepted principles of geotechnical engineering as practiced in the Puget
Sound area at the time this report was submitted. We make no warranty, either express
or implied. Please call me if there are any questions regarding this report.
