As outlined in our proposal memorandum dated June 25, 2004, our scope of work was limited to
geotechnical research and letter preparation. We received your verbal authorization for our
supplementary services on June 25, 2004. This letter has been prepared for the exclusive use
of Match - MacDonald and their consultants, for specific application to this project, in accordance
with generally accepted geotechnical engineering practice.
PROJECT DESCRIPTION
The project site consists of an existing single - family home with associated parking and a
currently undeveloped portion of the subject property north of the existing home that is being
short - platted into four lots. The existing residence (located on Lot 1) is located at 4404 - 160
Street, Tukwila, Washington. Lots 1, 2, & 3 slope downward to the north with an approximate
inclination of about 5 to 7 percent (measured in field), while proposed Lot 4 gradually steepens
its downward slope to the northwest and develops a maximum inclination of about 45 percent

(measured in field) throughout the northernmost portion of the property. Site boundaries are
generally delineated by a slope to the north, residential property to the east and west, and by
160 Street to the south. At the time of our recent site reconnaissance, June 25, 2004, the new
driveway and utilities to Lots 2, 3, and 4 had been installed.
Lot 1 is currently occupied by an existing single - family home with associated parking. Lots 2 &
3 have been cleared and stripped as the new driveway and utilities have been installed. The
two lots slope gently downward to the north. Lot 4 is mostly vegetated by cut grass, mature
douglas fir, alder, and maple trees. In areas that are not currently landscaped the under -story
consists of moderately thick groundcover including laurel and berry vines or bushes. Lot 4
gradually steepens its downward slope to the northwest and develops a maximum inclination of
about 45 percent (measured in field) throughout the northernmost portion of the property.
No indication of past slope instability, seeps, springs, or geologic contacts were observed within
or adjacent to the subject property were observed during our initial site work in 2002 or at the
time of our recent reconnaissance in 2004.
According to published geologic maps, the site is located within the Puget Lowland. Quaternary
sediments consisting of various glacial, fluvial, lake and marsh deposits dominate the region.
These sediments were deposited from the Puget Lobe of the Cordilleran continental ice sheet
during the Vashon Stade of the Fraser Glaciation. The geologic map entitled "Geology of the
Des Moines Quadrangle, Washington ", classifies the soils in the vicinity of the project site as
ground moraine (Qgt), which are characterized as mainly compacted unoxidized glacial till.
Our previously excavated test pit explorations encountered sandy soils of varying density, and
generally diverged fro the published geological mapping. Specifically, our on -site explorations
revealed approximately 6 inches of loose organic soil overlying about 2 feet of loose, moist, silty
sand with roots. Beneath the silty sand, we encountered about 21/2 to 7%2 feet of sand with trace
silt and gravel. The sand continued to the termination of our test pits. In test pit TP -2, we
encountered a 1 -foot layer of medium dense, moist, silty, gravelly sand beneath the silty sand
before encountering the sand.
CONCLUSIONS AND RECOMMENDATIONS
In our opinion, based on our previous site explorations and recent review of site conditions, we
offer the following geotechnical recommendations concerning the critical areas designations of
the Lots 1, 2, and 3.
• Slope Stability: The "Map Showing Relative Slope Stability in Part of West -
Central King County, Washington" prepared by Robert D. Miller, classifies the

slopes in the vicinity of the project site as Class 1. These slopes are generally
stable even where modified by man. Sections of the proposed property may
extend into a region classified as Class 2. Class 2 slopes are normally stable but
may become unstable due to man's activities. It is our interpretation that only
northern portion of lot 4 is mapped to contain Class 2 slopes, no development is
planned in this area.
• Topography: Lots 1, 2, and 3 are generally flat to very gently sloping downward
to the north. The maximum observed slope inclination at the time of our initial site
work and recent reconnaissance was on the order of 5 to 7 percent. Lot 4 was
the only lot on which slopes in excess of 7 percent, and extending up to 45
percent were observed.
• Evidence of Slope Instability: We did not observe any evidence of past slope
instability during our 2002 or 2004 site work.
• Critical Areas Designation: Based on the conclusions and recommendations in
our February 22, 2002 Geotechnical Engineering Report and our June 3, 2002
Infiltration Test Report, it is our opinion that the critical areas designation of
potential geologic instability be removed from Lots 1, 2, and 3 of the Sunnyvale
Gardens short plat.
The conclusions and recommendations presented in this letter are based, in part, on our
previous subsurface explorations; therefore, if variations in the subsurface conditions are
observed at a later time, we may need to modify this report to reflect those changes. AMEC is
available to provide geotechnical monitoring, soils testing, and other services throughout
construction.

Re: Tukwila Short Plat No. L01 -019
Dear Mr. Morrow,
We are the owners of the three lots of the above - mentioned short plat. We
understand from Pat Stephan of First American Title Company that he spoke with
you last week regarding said short plat, and that you would consider allowing us
to re- record the Sensitive Area Covenant so that it reflects the correct sensitive
areas now that we have it short- platted. Amec Earth & Environmental, Inc. has
been our engineers throughout this project, and we are enclosing their letter
dated June 25, 2004 addressing this issue. We are also enclosing a copy of the
Sensitive Area Covenant document that we would like to re- record, clarifying the
sensitive areas.
I hope this letter from the engineers contains the information that you require. If
the wording of the letter is sufficient for your needs, I will deliver the original to
you. As we have a sale of the three lots pending, we would like to proceed with
re- recording the Sensitive Area Covenant provided we have your approval based
on the enclosed letter from the engineers. Provided the information in the
engineering letter is sufficient, please let me know what I need to do in order to
get the Sensitive Area Covenant re- recorded. I'm not sure how the process
would work and I appreciate any guidance you can give me.
Thank you for your help with this matter. Please feel free to give me a call at
425 -413 -0777 if you have any questions. Your assistance is very much
appreciated.
Sincerely,

Director Public Works
Dear Jim,
My name is Sharon Mann, real estate agent representing the property at 4404 South 160 ( Short
Plat L01 -019). I was in the office last week and spoke to Jill Mosqueda about the possibility of being able
to record this short plat by putting up a bond. Prior to speaking to her, I spoke to the mayor at the counter
and he said he didn't see any reason why not. Jill did say that the policy of the City regarding putting up
bonds has recently changed but that you would consider it if I provided you with proper information about
the project.
I have attached the contract between the owners and the Green River Construction regarding the
road and utility improvements. Plus I have attached a copy of the owners bonds and a copy of the
contractor's license to do business in the City. In addition, this contractor is a citizen of the City and has
done construction in the City for years.
In speaking with Jerry Knutzen from Green River Construction, here is an update on the project.
The dirt for the road base has been brought on site.
The water connection has been made in the street.
Water pressure and purification need to be done -today or tomorrow.
Infiltration drains in the road done today.
Put in the 3 water service connection for the three new lots. Friday to be done.
Sanitary sewer to be tied into in the street on Thursday.
Friday —run 2" line and laterals to property lines.
Utility tie ins and conduit to be laid first of next week.
Rough road grade to be done next week.
Overlay to be done following week — weather permitting.
This is all happening but not in time for the purchase and sale agreement on the front house to
close in time at the end of the month. We need to file the Plat in order to get a legal description for the front
house and to order the final Title insurance for the lender. The buyer's rate lock expires at the end of the
month and the rates have taken a turn up and look like they are going to stay on the upturn. If we could
record this plat early next week , we can still make month ending deadline.
Please consider letting this plat record. We have a good start on the improvements and have a
great and reputable Contractor under contract to complete the project in addition to having a ample bond in
place.

RE: L01 -019
Sunnydale Gardens Short Plat
I received your letter requesting an extension of the expiration date for the Sunnydale
Gardens short plat on April 11 The short plat was granted preliminary approval on April
26, 2002 and was due to expire one year from that date unless you had complied with the
conditions of approval and recorded the documents. In your request for an extension you
state that the owner has not been able to complete the necessary work due to a delay in
coordinating the crossing of the 60 inch Seattle Public Utilities water main to reach the
property. Therefore a one year extension for completion of the infrastructure covered by
permit PW03 -009 and recording has been approved by the Short Subdivision Committee.
In your letter you express a desire to bond some of the road and utility construction
discussed in the preliminary approval letter. This will be treated as a separate request
addressed to the Public Works Director Jim Morrow. Please be specific about which
elements you propose to delay and why they cannot be constructed at this time.
All required infrastructure must be constructed or bonded and the final approved short plat
must be filed with the King County Department of Records by April 26, 2004, two years
from the date of the preliminary approval, or the application will expire. No further
extensions are possible.
If you have any questions about the short plat process or approval conditions please call
me at (206) 433 -7141.

property.
To date, the water extension plans are approved by Highline Water District, the private
road and drainage has been turned in (for its final review), and sewer work has been
coordinated with Val Vue Sewer District.
We expect the short plat, with improvements bonded, to be recorded before the end of
April.
Thank you for your assistance.

Our Infltration tests were performed in general accordance with thieR OSecies pres cribed in the.
iwPA manual entitled On -Sate Wastewater Treatment and Disposal 5 -c igle4% : t as modifiec
by AMEC. Speclfic�lly, a test hole was excavated to the desired infiitra eel test depths
6- inch - diameter PVC pipe was tamped approdrnately 6 inches into undlsturbatd soil at the bottom
of the teat hole, and the test hole was partially backfilled with soil. The pipe was then filled twice
with 12 inches of water, and because the water seeped away in slightly more than 10 minutes i
TI-1-1 and slightly less than 10 minutes In TH -2, no soaking period was deemed necessary. The
pipe was then tilled with '6 inches of water, and, because site soils at the. Infiltration troncr
elevations are rapidly permeable, the time was .rooard®d through a total drop of 6 inches. V,l
repeated this procedure three times at the test location and subsequently calculated the average
rate of the three trials. After completion of the test, the PVC pipe was extracted•end the test hole
was completely baokfiited.
INFILTRATION TEST RESULTS LPA
Our results for the Infiltration trench on Lot 1 yielded an infiltration rate of 2.5 minutes per Inch aruq
a rate of 1.5 minutes per Inch for the infiltration trench on Lot 2. A safety factor o a leas fivLI,
should be applied for design purposes, to account for variations within the soil deposit. Th+
infiltration rate for site soils at the proposed trench subgrade elevations, with an applied safetjr
factor of two should be l5 minutes per inc;tt_�or Lot 1 and 3 i minutes per inch for j..ot 2.
-- - - . L
Due to site conditions at the time of infiltration testing, soils in the infiltration trench planned for Lc't
3 could not be tested. Subsurface explorations made for our geotechnicel report of February 2,
2002, and explorations made by Bruce S. MacVeigh on May. 9, 2001, indicate.that similar sandhi
soils probably underlie the proposed trench on Lot 3. We recommend an infiltration rate, after
safety factor of 2 has been applied, of 5 minutes per inch for the infiltration trench planned forth
west side of Lot 3,

RE: L01 -019
Sunnydale Gardens Short Plat
Dear Mr. MacVeigh,
Based upon your March 9 submittal the City has the following comments on your short
plat:
1. The proposed road exceeds the 200 foot length allowed for private access roads.
You will need to either revise the design to meet the minimum standards for a public
road or apply to the Short Subdivision Committee for an exception from the
standard based on the criteria and procedures at TMC 17.28.010.
2. The private access road easement should not be a separate tract, but should cross
over the individual parcels. It should also extend to the southernmost boundary of
Lot 4.
3. The existing garage cannot remain on Lot 2 on its own because a garage must be
accessory to a house on the same lot. You may either demolish the garage after
obtaining a permit from the City (contact Jim Dunaway at 206 - 431 -3670) or prior to
final approval post a bond for 150% of the cost of demolition if a new house will be
built on the lot within one year. If the new house is not built by that deadline the
owner must agree to let the City demolish the garage at the owner's expense.
4. Please discuss the issue of the proposed private hydrant with Steve Kohler in the
Tukwila Fire Department (206) 575 -4404.
5. See attached comments from the Public Works Department.

GEOTECHNICAL REPORT GUIDELINES
A geotechnical report helps determine if the proposal for a site is appropriate. A
geotechnical report contains information used to design retaining walls, foundations,
hazardous waste facilities, and infiltration systems, such as trench drains, sand filters
and septic drain fields. Geotechnical reports also supply information for settlement
analysis, liquefaction, structural fill, and storm water design.
The City requires geotechnical reports for the following:
• Projects in the sensitive area overlay
• Riverbank Stability
• Hazardous Waste Facility Design
• Retaining walls over 4 feet high
• Grading in excess of 500 cubic yards
• Surface water ponds and vaults
• Storm drainage feasibility report
In addition to the above cases, the City may request a geotechnical report when the
project or site conditions warrant.
The City sends each Geotechnical Report to a geotechnical firm of its choice for an
independent review. The Applicant pays the cost of the review.
In addition to the geotechnical report, which must be submitted to the City with the
plans and specifications, the Applicant /Owner shall provide completed affidavits and a
covenant, all of them notarized and in a recordable format. Samples are included at
the end of this Bulletin.
Infiltration
All infiltration design must be accompanied by a feasibility evaluation per the King
County Surface Water Design Manual.
Report Requirements
The geotechnical report must be prepared, stamped, signed, and dated by a
Washington State licensed geotechnical engineer as defined in the Public Works
Infrastructure Design and Construction Manual.

PUBLIC 1 ,N0k1KS
This letter presents the results of our review of a geotechnical engineering report for the
proposed Hoskin Short Plat project. The project site will be located north of the existing
residence at 4404 South 160 Street, Tukwila, Washington. The purpose of our work is to offer
an opinion as to the appropriateness and adequacy of the geotechnical engineering report
submitted with the permit application.
The geotechnical report for this project was prepared by Amec Earth & Environmental, Inc.
(AMEC) and dated February 22, 2002. The report presents the results of three test pit
explorations and geotechnical recommendations for site development. The test pit explorations
extended to depths of 5 to 11 feet and encountered loose to medium dense sand. The report
provided descriptions of the site geology and subsurface soil and groundwater conditions. It
provided opinions and recommendations regarding site development, foundations and earth
pressures, slope stability, buffers and setbacks, and other general geotechnical design issues.
Lots 1, 2, and 3 of the proposed short plat appear to be Class 1 areas of potential geologic
instability, while Lot 4 meets the criteria for a Class 3 area because it contains slopes steeper
than 40 percent. Our review of site conditions on proposed Lot 4 indicates that a minimum
setback distance would not be required if the structure is located as shown in the AMEC report.
Based on our review of the AMEC report and our observations of current site conditions, we
generally concur with the opinions and recommendations provided. It is our opinion that the
report meets generally accepted geotechnical principles and practice in this area.
It is not clear from the documents we reviewed whether or not the proposed short plat
development will include use of infiltration facilities to dispose of storm water. Guidelines for

determining soil infiltration rates are presented in the King County, Washington Surface Water
Design Manual (September 1998), Section 5.4.1. While the AMEC report does not address
infiltration rates of on -site soils, it appears that this will be necessary if the project is to involve
use of on -site infiltration.
In our opinion, the geotechnical report prepared for this project meets the generally accepted
standards of practice in this area and meets the minimum standards of Tukwila Municipal
Code 18.45.080 E. If necessary, the geotechnical engineer should review the current
development plans with regard to handling of storm water and provide a supplemental letter to
address infiltration rates.
We appreciate the opportunity to be of service. If you have any questions I am available at

RE: Question regarding the practice of Geotechnical Engineering
Dear Mr. Morrow:
STATE OF WASHINGTON
First let me apologize for the time delay in responding to your department's request of
January 11, 2002. You had written to our office about obtaining clarification of my
phone conversation with Mr. Bruce MacVeigh and his subsequent letter to your office in
which he objected to your restriction on his practice as a professional engineer in the area
of geotechnical engineering. Hopefully this letter will help you in this regard.
Mr. MacVeigh correctly states there is no licensing recognition as a "Geotechnical
Engineer" as there is no examination offered for engineers to become qualified within
Geotechnical Engineering. In the state of Washington those who are authorized to hold
the title of and practice as a professional engineer have passed at least one of over 18
different examinations offered. Our experience is that those individuals who work within
the area of geotechnical engineering are those who have passed the examination in civil
engineering. That examination does include portions or modules that allow candidates to
solve questions in geotechnical subjects.
In the state of Washington, as per the Engineer's Registration Act chapter 18.43 RCW, an
individual is licensed or registered as a "Professional Engineer" and may practice in any
branch of the profession of engineering. That is as long as that practice falls within
his/her area of expertise, regardless of the branch that he /she was initially licensed and
the work is performed in a competent manner. This is because Washington's law is
known as a professional practice act as opposed to a discipline specific act. This would
mean that not only could a professional engineer qualified in civil engineering practice in
the area of geotechnical subjects but also engineers qualified in any of the other areas or
branches of engineering such as electrical, mechanical.
Administrative services provided by the Department of Licensing which has a policy of providing equal access
to its services. If you need special accommodation, please call (360) 66 -1575 or TTY (360) 586 -2788.
Mr. MacVeigh takes issue with how your department has evaluated his qualification to
practice within the city's jurisdiction. He believes that the information he obtained in our
conversation and in the Engineer's Registration Act prevents your department's ability to
restrict or add additional qualifications to his practice. That is not correct, as we merely
confirmed with him what has been discussed so far within this letter about the provisions
within our registration law and noting that the city could not regulate the practice of
engineering.
Your expectation that a professional engineer be able to demonstrate sufficient expertise
in the technical areas you are evaluating is exactly what the above discussion is based
upon. What we have seen in the materials you provided would suggest that your
approach is consistent with what the Board would typically find as acceptable. Your
department's procedure in this area appears to be similar to what some local governments
are using in others areas. For instance individuals who practice structural engineering
may be required to have a licensed structural engineer design or supervise the design a
structural project if a local jurisdiction requires that additional level of professional
certification.
Since we have not personally examined or reviewed Mr. MacVeigh's experience or the
specific criteria you are using to judge his suitability we cannot further comment on your
approach.
It is hoped that this letter addresses the concerns that have been raised on this issue. If
you have any questions please feel free to call me at (360) 664 -1566.

Ronald L. Torrence, PLS

Client shall grant or obtain free access to the project site for all equipment and personnel necessary for Shannon & Wilson to perform its services.
ARTICLE 6 — STANDARD OF CARE / ABSENCE OF WARRANTIES / NO RESPONSIBILITY FOR SITE SAFETY OR CONTRACTOR'S
PERFORMANCE
Standard of Care
The standard of care for all professional services performed or furnished by Shannon & Wilson under this Agreement shall be the skill and care ordinarily
exercised by other members of Shannon & Wilson's profession, providing the same or similar services, under the same or similar circumstances, at the same
time and locality as the services were provided by Shannon & Wilson. The construction, alteration, or repair of any object or structure by Shannon & Wilson
shall be performed in a good and workmanlike manner in accordance with general industry standards, and conform to this Agreement. Shannon & Wilson
warrants for one (I) year from substantial completion of the Work, all goods delivered hereunder shall be new and free from defects in material or
workmanship, and shall conform to the specifications, drawings, or sample(s) specified or furnished, if any, and shall be merchantable and fit for their
intended purposc(s). Shannon & Wilson warrants that Shannon & Wilson has good and marketable title to all goods delivered hereunder, and that all goods
delivered hereunder shall be free and clear of all claims of superior title, liens, and encumbrances of any kind.
Subsurface explorations and testing identify actual subsurface conditions only at those points where samples are taken, at the time they are taken. Actual
conditions at other locations of the project site, including those inferred to exist between the sample points, may differ significantly from conditions that exist
at the sampling locations. The passage of time or intervening causes may cause the actual conditions at the sampling locations to change as well.
Interpretations and recommendations made by Shannon & Wilson shall be based solely upon information available to Shannon & Wilson at the time the
interpretations and recommendations arc made.
Shannon & Wilson shall be responsible for the technical accuracy of its services, data, interpretations, and recommendations resulting therefrom, and Client
shall not be responsible for discovering deficiencies therein. Shannon & Wilson shall correct any substandard work without additional compensation, except
to the extent that such inaccuracies are directly attributable to deficiencies in Client - furnished information.
No 'Warranties
Shannon & Wilson makes no guarantees or warranties, express or implied, under this Agreement or otherwise, about Shannon & Wilson's professional
services.
Client - Furnished Documents
Shannon & Wilson may use requirements, programs, instructions, reports, data, and information furnished by Client to Shannon & Wilson in performing its
services under this Agreement. Shannon & Wilson may rely on the accuracy and completeness of requirements, programs, instructions, reports, data, and
other information furnished by Client to Shannon & Wilson. Client shall, only to the fullest extent permitted by law, waive any claims against Shannon &
Wilson and its subcontractors, and indemnify and hold Shannon & Wilson and its subcontractors harmless from any claims, liability, or expenses (including
reasonable attorneys' fees and costs) arising from Shannon & Wilson's reliance on Client- furnished information, except to the extent of Shannon & Wilson's
and its subcontractor's negligent or wrongful acts, errors, omissions, or breach of contract.
Site Damage
Shannon & Wilson shall take reasonable precautions to minimize damage to the project site, but it is understood by Client that, in the normal course of
Shannon & Wilson's services, some project site damage may occur, and the correction of such damage is not part of this Agreement unless so stated in
Shannon & Wilson's Proposal. Client shall, only to the fullest extent permitted by law, waive any claims against Shannon & Wilson and its subcontractors,
and indemnify and hold Shannon & Wilson and its subcontractors harmless from any claims, liability, or expenses (including reasonable attorneys' fees and
costs) arising from any project site damage caused by Shannon & Wilson, except to the extent of Shannon & Wilson's and its subcontractor's negligent or
wrongful acts, errors, omissions, or breach of contract.
Buried Structures
If there are any buried structures and/or utilities on the project site where subsurface explorations are to take place, Client shall provide Shannon & Wilson
with a plan showing their existing locations. Shannon & Wilson shall contact a utility locator service to request that they identify any public utilities.
Shannon & Wilson shall use reasonable care and diligence to avoid contact with buried structures and/or utilities as shown. Shannon & Wilson shall not be
liable for any loss or damage to buried structures and/or utilities resulting from inaccuracy of the plans, or lack of plans, or errors by the locator service
relating to the location of buried structures and/or utilities. Client shall, only to the fullest extent permitted by law, waive any claims against Shannon &
Wilson and its subcontractors, and indemnify, and hold Shannon & Wilson and its subcontractors harmless from any claims, liability, or expenses (including
reasonable attorneys' fees and costs) arising from damage to buried structures and/or utilities caused by Shannon & Wilson's sampling, except to the extent of
Shannon & Wilson's and its subcontractor's negligent or wrongful acts, errors, omissions, or breach of contract.
Aquifer Cross- Contamination
Despite the use of due care, unavoidable contamination of soil or groundwater may occur during subsurface exploration when drilling or sampling tools are
advanced through a contaminated area, linking it to an aquifer, underground stream, or other hydrous body not previously contaminated and capable of
spreading contaminants off the project site. Because Shannon & Wilson is powerless to totally eliminate this risk despite use of due care, and because
sampling is an essential clement of Shannon & Wilson's services, Client shall, only to the fullest extent permitted by law, waive any claims against Shannon
& Wilson and its subcontractors, and indemnify and hold Shannon & Wilson and its subcontractors harmless from any claims, liability, or expenses (including
reasonable attorneys' fees and costs) arising from cross - contamination caused by Shannon & Wilson's sampling, except to the extent of Shannon & Wilson's
and its subcontractor's negligent or wrongful acts, errors, omissions, or breach of contract.

If opinions of probable construction costs are included in Shannon & Wilson's Proposal, Shannon & Wilson's opinions of probable construction costs shall be
made on the basis of its experience and qualifications and represent its judgment as a professional generally familiar with the industry. Opinions of probable
construction costs are based, in part, on approximate quantity evaluations that are not accurate enough to permit contractors to prepare bids. Further, since
Shannon & Wilson has no control over: the cost of labor, materials, equipment, or services furnished by others; the contractor's actual or proposed
construction methods or methods of determining prices; competitive bidding; or market conditions, Shannon & Wilson cannot and does not guarantee that
proposals, bids, or actual construction cost will not vary from opinions of the components of probable construction cost prepared by Shannon & Wilson. If
Client or any contractor wishes greater assurance as to probable construction cost, Client or contractor shall employ an independent cost estimator.
Review of Contractor's Shop Drawings and Submittals
If review of a contractor's shop drawings and submittals are included in Shannon & Wilson's Proposal, Shannon & Wilson shall review and take appropriate
action on the contractor's submittals, such as shop drawings, product data, samples, and other data, which the contractor is required to submit, but solely for
the limited purpose of checking for general overall conformance with Shannon & Wilson's design concept. This review shall not include a review of the
accuracy or completeness of details, such as quantities; dimensions; weights or gauges; fabrication processes; construction means, methods, sequences or
procedures; coordination of the work with other trades; or construction safety precautions, all of which are the sole responsibility of the contractor. Shannon
& Wilson's review shall be conducted with reasonable promptness while allowing sufficient time, in Shannon & Wilson's judgment, to permit adequate
review. Review of a specific item shall not be construed to mean that Shannon & Wilson has reviewed the entire assembly of which the item is a component.
Shannon & Wilson shall not be responsible for any deviations by the contractor in the shop drawings and submittals from the construction documents, which
are not brought to the attention of Shannon & Wilson by the contractor in writing.
Construction Observation
If construction observation is included in Shannon & Wilson's Proposal, Shannon & Wilson shall visit the project site at intervals Shannon & Wilson deems
appropriate, or as otherwise agreed to in writing by Client and Shannon & Wilson, in order to observe and keep Client generally informed of the progress and
quality of the work. Such visits and observations arc not intended to be an exhaustive check or a detailed inspection of any contractor's work, but rather are to
allow Shannon & Wilson, as a professional, to become generally familiar with the work in progress in order to determine, in general, whether the work is
progressing in a manner indicating that the work, when fully completed, will be in accordance with Shannon & Wilson's general overall design concept.
Shannon & Wilson's authority shall be limited to observing, making technical comments regarding general overall compliance with Shannon & Wilson's
design concept, and rejecting any work which it becomes aware of that does not comply with Shannon & Wilson's general overall design concept. Shannon
& Wilson's acceptance of any non - conforming work containing latent defects or failure to reject any non - conforming work not inspected by Shannon &
Wilson shall not impose any liability on Shannon & Wilson or relieve any contractor from complying with their contract documents. All construction
contractors shall be solely responsible for construction site safety, the quality of their work, and adherence to their contract documents. Shannon & Wilson
shall have no authority to direct any contractor's actions or stop any contractor's work.
If Shannon & Wilson is not retained to provide construction observation of the implementation of its design recommendations, Client shall, only to the fullest
extent permitted by law, waive any claims against Shannon & Wilson, and indemnify and hold Shannon & Wilson harmless from any claims, liability, or
expenses (including reasonable attorneys' fees and costs) arising from the implementation of Shannon & Wilson's design recommendations, except to the
extent of Shannon & Wilson's and its subcontractor's negligent or wrongful acts, errors, omissions, or breach of contract.
No Responsibility for Site Safety
Except for its own subcontractors and employees, Shannon & Wilson shall not: supervise, direct, have control over, or authority to stop any contractor's work;
have authority over or responsibility for the means, methods, techniques, sequences, or procedures of construction selected by any contractor; be responsible
for safety precautions and programs incident to any contractor's work; or be responsible for any failure of any contractor to comply with laws and regulations
applicable to the contractor, all of which are the sole responsibility of the construction contractors. This requirement shall apply continuously, regardless of
time or place, and shall in no way be altered because a representative of Shannon & Wilson is present at the project site performing his/her duties.
Notwithstanding anything to the contrary, Shannon & Wilson shall never be deemed to have assumed responsibility for the project's site safety by either
contract or conduct. No act or direction by Shannon & Wilson shall be deemed the exercise of supervision or control of any contractor's employees or the
direction of any contractor's performance. Any direction provided by Shannon & Wilson shall be deemed solely to ensure the contractor's general overall
compliance with Shannon & Wilson's design concept.
No Responsibility for Contractor's Performance
Except for its own subcontractors and employees, Shannon & Wilson shall not be responsible for safety precautions, the quality of any contractor's work, or
any contractor's failure to furnish or perform their work in accordance with their contract documents.
Except Shannon & Wilson's own employees and its subcontractors, Shannon & Wilson shall not: be responsible for the acts or omissions of any contractor,
subcontractor or supplier, or other persons at the project site, or otherwise furnishing or performing any work; or for any decision based on interpretations or
clarifications of Shannon & Wilson's design concept given without the consultation and concurrence of Shannon & Wilson.
Approval of Contractor's Applications for Payment
If approval of a contractor's applications for payment are included in Shannon & Wilson's Proposal, Shannon & Wilson shall review the amounts due the
contractor and issue a recommendation about payment to Client. Shannon & Wilson's review and approval shall be limited to an evaluation of the general
progress of the work and the information contained in the contractor's application for payment and a representation by Shannon & Wilson that to the best of
the Shannon & Wilson's knowledge, the contractor has performed work for which payment has been requested, subject to further testing and inspection upon
substantial completion. The issuance of a recommendation for payment shall not be construed as a representation that: Shannon & Wilson has made an
exhaustive check or a detailed or continuous inspection check of the quality or quantity of the contractor's work; approved the contractors means, methods,
sequences, procedures, or safety precautions; or that contractor's subcontractors, laborers, and suppliers have been paid.
ARTICLE 7 — CONFIDENTIALITY AND USE OF DOCUMENTS
Confidentiality
Shannon & Wilson agrees to keep confidential and to not disclose to any person or entity (other than Shannon & Wilson's employees and subcontractors),
without the prior consent of Client, all information furnished to Shannon & Wilson by Client or learned by Shannon & Wilson as a result of its work on the
project; provided however, that these provisions shall not apply to information that: is in the public domain through no fault of Shannon & Wilson; was
previously known to Shannon & Wilson; or was independently acquired by Shannon & Wilson from third - parties who were under no obligation to Client to
keep said information confidential. This paragraph shall not be construed to in any way restrict Shannon & Wilson from making any disclosures required by

Attachment to . dart of Proposal 21 -3- 15003 -001
Date: January 28, 2002
To: Ms. Jill Mosqucda
City of Tukwila Public Works Dept.
Important Information About Your Geotechnical/Environmental Proposal
More construction problems are caused by site subsurface conditions than any other factor. The following suggestions and observations
are offered to help you manage your risks.
HAVE REALISTIC EXPECTATIONS.
If you have never before dealt with geotechnical or environmental issues, you should recognize that site exploration identifies actual
subsurface conditions at those points where samples are taken, at the time they are taken. The data derived are extrapolated by the
consultant, who then applies judgment to render an opinion about overall subsurface conditions; their reaction to construction activity;
appropriate design of foundations, slopes, impoundments, recovery wells; and other construction and/or remediation elements. Even under
optimal circumstances, actual conditions may differ from those inferred to exist, because no consultant, no matter how qualified, and no
subsurface program, no matter how comprehensive, can reveal what is hidden by earth, rock, and time.
DEVELOP THE SUBSURFACE EXPLORATION PLAN WITH CARE.
The nature of subsurface explorations —the types, quantities, and locations of procedures used —in large measure determines the
effectiveness of the geotechnical/environmental report and the design based upon it. The more comprehensive a subsurface exploration
and testing program, the more information it provides to the consultant, helping to reduce the risk of unanticipated conditions and the
attendant risk of costly delays and disputes. Even the cost of subsurface construction may be lowered.
Developing a proper subsurface exploration plan is a basic element of geotechnical /environmental design, which should be accomplished
jointly by the consultant and the client (or designated professional representatives). This helps the parties involved recognize mutual
concerns and makes the client aware of the technical options available. Clients who develop a subsurface exploration plan without the
involvement and concurrence of a consultant may be required to assume responsibility and liability for the plan's adequacy.
READ GENERAL CONDITIONS CAREFULLY.
Most consultants include standard general contract conditions in their proposals. One of the general conditions most commonly employed
is to limit the consulting firm's liability. Known as a "risk allocation" or "limitation of liability," this approach helps prevent problems at
the beginning and establishes a fair and reasonable framework for handling them, should they arise.
Various other elements of general conditions delineate your consultant's responsibilities. These are used to help eliminate confusion and
misunderstandings, thereby helping all parties recognize who is responsible for different tasks. In all cases, read your consultant's general
conditions carefully and ask any questions you may have.
HAVE YOUR CONSULTANT WORK WITH OTHER DESIGN PROFESSIONALS.
Costly problems can occur when other design professionals develop their plans based on misinterpretations of a consultant's report. To
help avoid misinterpretations, retain your consultant to work with other project design professionals who are affected by the geotechn-
ical /environmental report. This allows a consultant to explain report implications to design professionals affected by them, and to review
their plans and specifications so that issues can be dealt with adequately. Although some other design professionals may be familiar with
geotechnical /environmental concerns, none knows as much about them as a competent consultant.

OBTAIN CONSTRUCTION MONIT( NG SERVICES.
Most experienced clients also retain their consultant to serve during the construction phase of their projects. Involvement during the
construction phase is particularly important because this permits the consultant to be on hand quickly to evaluate unanticipated conditions,
to conduct additional tests if required, and when necessary, to recommend alternative solutions to problems. The consultant can also
monitor the geotechnical /environmental work performed by contractors. It is essential to recognize that the construction recommendations
included in a report are preliminary, because they must be based on the assumption that conditions revealed through selective exploratory
sampling are indicative of actual conditions throughout a site.
Because actual subsurface conditions can be discerned only during earthwork and /or drilling, design consultants need to observe those
conditions in order to provide their recommendations. Only the consultant who prepares the report is fully familiar with the background
information needed to determine whether or not the report's recommendations are valid. The consultant submitting the report cannot assume
responsibility or liability for the adequacy of preliminary recommendations if another party is retained to observe construction.
REALIZE THAT ENVIRONMENTAL ISSUES MAY NOT HAVE BEEN ADDRESSED.
If you have requested only a geotechnical engineering proposal, it will not include services needed to evaluate the likelihood of
contamination by hazardous materials or other pollutants. Given the liabilities involved, it is prudent practice to always have a site reviewed
from an environmental viewpoint. A consultant cannot be responsible for failing to detect contaminants when the services needed to
perform that function are not being provided.
ONE OF THE OBLIGATIONS OF YOUR CONSULTANT IS TO PROTECT THE SAFETY, PROPERTY, AND WELFARE OF
THE PUBLIC.
A geotechnical /environmental investigation will sometimes disclose the existence of conditions that may endanger the safety, health,
property, or welfare of the public. Your consultant may be obligated under rules of professional conduct, or statutory or common law, to
notify you and others of these conditions.
RELY ON YOUR CONSULTANT FOR ADDITIONAL ASSISTANCE.
Your consulting firm is familiar with several techniques and approaches that can be used to help reduce risk exposure for all parties to a
construction project, from design through construction. Ask your consultant, not only about geotechnical and environmental issues, but
others as well, to learn about approaches that may be of genuine benefit.

The City has reviewed the geotechnical letter from AMEC Earth and Environmental that
you submitted on November 16 This does not meet the requirements set forth by
Public Works in the Geotechnical Report Handout. At a minimum this requires
submittal of a geotechnical report written, signed, stamped and dated by a geotechnical
engineer based on an actual site investigation performed by that geotechnical engineer.
A geotechnical engineer is a Washington State licensed civil engineer who has
experience in the application of soil mechanics in the investigation, evaluation and
design of civil works. Experience must include activities given in the City's October
25, 2001 letter (see attached).
The project will not move forward until a report meeting the above requirements has
been submitted to the City. If you have any questions about these comments please call
me at (206) 433 -7141 or Jill Mosqueda at (206) 433 -0179.

Thank you for your letter subject: LO1 -019, Sunnydale Gardens Short Plat, dated
November 30, 2001. Unfortunately the conclusions reached are patently unacceptable,
and are in distinct violation of Washington State Department of Licensing code.
Communications between this office and Ron Terrance, P.L.S., Deputy Executive
Director of the State Board of Registration ((360) 664 -1564) confirms that there is
no licensing recognition of a "Geotechnical Engineer ". The nature of work
indicated for this project comes under the category of "Licensed Professional Civil
Engineer ", a certification this office has held and actively practiced since 1980.
Restrictions on the practice of a State licensed professional by subordinate
jurisdictions is illegal. The requirements to meet additional qualifications to
practice State sanctioned activities by subordinate jurisdictions is illegal. The limits
and nature of activities are soley at the descretion of the licensed profession himself
based on personal knowledge, education and practical experience, and not subject to
outside restriction. The documented copies of similar projects prepared and
accepted by various jurisdictions over the last several years indicates that this office
has achieved appropriate competence in this level of geotechnical evaluation.
The initial disapproval of the submitted geotechnical report for this project on September
7, 2001 requested "copies of other geotechnical reports" to allow the City to decide if it
would allow the licensed engineer to perform this work within the City.
Several old reports were submitted, generally of the same level of work needed for this
project. This was done to expedite the project for the client. The City was notified that
this requirement was inappropriate and illegal under State code.
A second disapproval of October 25, 2001 said that the submitted reports were not
adequate and that the City would not accept the original submitted geotech report.

In response, a supplemental report was prepared by AMEC Earth and Environmental, a
recognized geotechnical firm, which included a site inspection. The supplemental report
specifically addressed and confirmed the contents of this office's original report. A
representative of AMEC related to this office that the original report should have been
sufficient for the single residential lot involved.
A third disapproval letter was prepared on November 30, 2001, stating that the work by
AMEC was unacceptable, since it did not involve an "actual site investigation ". The
meaning and scope of this is unclear. The site had been investigated, including field soil
logs, by this office, and by site visit by an AMEC representative.
The owner of the site, Mark MacDonald of March- MacDonald, Inc., a general contractor,
is aware of the situation and preparing to take formal action in the event this situation is
not quickly resolved in a satisfactory manner.
It is unclear if the situation has arisen due to inexperienced but dedicated staffing or if the
City unofficially has a problem with the development of the site or the owner himself.
The reading of the above chain of actions by the City allows this to remain a question.
Attached are an expanded set of copies of previous geotechnical evaluations and related
studies for various projects prepared by this office in recent years. Prior to 1996/97 or so,
the number of formal geotechnical evaluations drops off since it was less in vogue then to
require separate evaluations for residences beyond the normal design calculations for safe
construction (basement walls, retaining walls, etc.). These provided are a sample. The
actual number of projects requiring geotechnical expertise is probably about 5 to 10 per
year over the last 15 years, including foundation evaluations and retaining walls. All
listed reports involve soil stability evaluation relating to residential construction.
It is the policy of this office to provide engineering evaluation and analysis at a level
appropriate to the specific project. To provide wildly more complex (and expensive)
evaluations and/or site investigations than is appropriate would place this office under
danger of disciplinary action by the Board of Registration for distinct ethics violations
and fraud in public representations.

The following information is reiterated, with some clarification's, from the previous letter o
reference this subject, dated October 12, 2001:
In addition, this office (as part of the firm Clark, Coleman and Rupeiks of Seattle)
personally prepared final extraction and site restoration plans for the old Meyers Way
sand pit in White Center, including the removal of the last 1.3 million cubic yards from
the 40 acre site, performing site restoration supervision over a three year period from
1985 to 1988. Specific soil slope stability calculations were prepared for this work by
Terra Associates (Anil Butail, P.E.).) The pit walls were 120 feet high pure Indianola
sand.
As an active duty Army Corps of Engineer Officer, graduated near top of the class in both
Engineer Officer's Basic Course and Engineer Officer's Advanced Course, both at Ft.
Belvoir, VA. Both courses included detailed soil testing procedure training and site soil
stability evaluation training.
While on both active and reserve duty, designed and supervised construction of timber
trestle bridges, underground bunkers (timber) and training sites with timber shored
retaining walls. Soil stability and construction characteristics were primary design
parameters in these projects.
z
Also. as an Army Corps of Engineer (Reserve) Officer, supervised the start up and
operation of a shale quarry at Yakima Training Center, and the operation of the 150 TPH
crushing and screening plant (and the 150 TPH asphalt mixing plant) in the 1990's. The
mixing plant work entailed specific mix designs based on WSDOT material
specifications.
Personally supervised the establishment of an on -site gravel pit/quarry to support the dam
enlargement and raising at Spada Lake in Snohomish County in 1982. Was the on -site
licensed engineer for the contractor (Constructors Pamco). The dam was raised
approximately 100 feet, and is earth fill, requiring coordination of the soil testing of the
placed material and coordinating with the design engineering firm, R.W. Beck of Seattle.
As Assistant Operations Officer for the 84th Engineer Battalion, oversaw operations of
the coral quarry on the island of Runit, Enewetak Atoll in 1978. In this capacity oversaw
the operation of the battalion soil testing laboratory for the operations.
Besides a BSCE from the University of Washington, this office has an additional Master's
Degree (MSCE) from the University of Washington, which specifically included graduate
level courses in soils engineering (from the late Professor Shariff) at UW.
Thank you for your attention. Feel free to contact this office if additional information is
needed to gain a timely approval for this geotechnical report and short plat.
Sincerely yours,
Bruce S. MacVeigh, P.E.

Dear Mr. MacVeigh: _ a

At your request, AMEC Earth and Environmental Inc. (AMEC) performed a site visit on o
November 9, 2001 to observe the surface conditions at the above referenced project site. In z
we have reviewed the geotechnical evaluation prepared by you, dated August 6, 2001. w
A fax copy of this evaluation and associated figures has been attached. o
o
AMEC has not observed the subsurface conditions of the project site. Therefore, we have ° u i
based our comments exclusively on the information presented in the geotechnical evaluation =
and the surface conditions observed at the time of our site visit. If the information presented in u o
the previous geotechnical evaluation is found to be incorrect, we may need to modify or z
supplement our comments. 0 co
We understand that current development plans call for sub - dividing the existing lot into 4 smaller z
residential lots. Proposed lots 1, 2, & 3 slope downward to the north with an approximate
inclination of about 5 to 7 percent (measured in field) to the north. Proposed lot 4 slopes steeply
to the northwest with an approximate inclination of about 45 percent (measured in field).
The surficial conditions at the project site are in general accordance with those described in
your geotechnical evaluation, except that at the time of our observations there was no indication
of the previously excavated test pits, and exposed soils were observed in the steeply sloping
areas of proposed lot four. East of the proposed lot 4 a large level pad was observed. We
interpret portions of this pad to consist of uncontrolled fill.
Based on our understanding of the currently proposed site utilization and on our site
observations, the proposed develop appears feasible from a geotechnical standpoint, contingent
on proper design and construction procedures. In addition no additional geotechnical evaluation
of proposed Tots 1, 2, & 3 appears necessary at this time. As recommended in your
geotechnical evaluation, a qualified geotechnical engineer should perform a design level
geotechnical evaluation before any development of lot 4 occurs.

Thank you for submitting five examples of work you have performed in the geotechnical
area. The City defines a geotechnical engineer as a professional civil engineer who has
at least four years of professional employment as a geotechnical engineer and has
experience in landslide evaluation.
The work examples you provided are of fairly simple projects and are dated 2001,
2000, and 1997. These work examples do not document experience in soil
classification from actual soil logs, estimation of soil strengths from laboratory testing,
slide analysis and remediation design, settlement estimations and remediation
measures, nor liquefaction potential with compensatory design.
I am sorry to inform you your work experience does not meet the City's criteria for a

This site is located on the north side of S. 160th Street, approximately two blocks east of w 0
42nd Avenue S. It consists of a rectangular parcel approximately 90 feet wide east -west
and approximately 633 feet deep north- south. The total site area is 56,970 SF or 1.31
acres. It is proposed to divide the parcel into three lots of approximately 9,150 SF each, c d
with the residual rear lot (Lot 4) being 29,430 SF. _
z �
The site will be accessed from S. 160th Street using a 20 foot wide private road w o
constructed along the west side of the property. The front 225 feet or so of the site has an ? o
existing single family residence and associated yard area. The slope downward to the U u)
north in this area is typically 5 to 10 %. From the back of this yard area, the site becomes o !-
fully wooded and after about 100 more feet slopes more steeply downward to the north = v
and northwest at a typical slope of 7 to 2.5:1 or 15 to 40 %, with a total drop in elevation F=.
being 150 feet. Some localized sections of this hillside exceed 40% along the northern
east property line. v c
t--
It is proposed by the future use of the site for residential lots to use only the higher more z
level area to the south, and to not disturb by clearing or grading the steeply sloped area.
(An exception is that at the top of the 15% slope on Lot 4, that a single family residence
be placed using appropriate geotechnical guidance. Except for the building area itself, no
grading or clearing would occur on Lot 4.)

Soils were observed in seven soil logs (copy attached), primarily in the southern more
gently sloped area of the site. The material encountered is a dense clean coarse sand to
depths of 8 feet or more. A clay loam layer was found a depth of 3.5 feet in only one hole
and appears to be an anomaly. Discussion with long time neighbors to the west of the
northern hill part of the site indicates that "the whole hillside is sand" based on the
construction of their home and site /yard work done over the years.
Investigation of the wooded slope itself found no erosion or sloughing of material. The
vegetation is full and consists of mature Douglas firs, alders, maple trees, etc. and dense
brush cover. No leaning of the trees or other signs suggested long term slope failure. No

surfacing groundwater was evident in the slope or at its base. While sands such as found
in the soil logs could erode easily if exposed, in practice the heavy groundcover prevents
this from happening to any noticeable degree.
The soils are part of a general Indianola series formation (18D and 18E), probably an
upland associated with Buckley type valley soils, with typical locally deep beds of dense
sands comprising upland hillsides along the older river valleys. (Several miles farther
north in the hillside below White Center, the sand pit there exhibited similar sands to
depths exceeding 120 feet.) The Erosion Factor listed for this soil type is 0.37 for semi -
disturbed surface layers, and 0.2 for dense undisturbed material, both fairly low on the
0.10 to 0.64 range.
Based upon this, the erosion potential for the slope on the site is low if the material is not
disturbed. With existing woods and groundcover left in place, erosion cannot be
considered a concern with this site.
The possibility of soil saturation and internal failure is low based upon the highly
permeable nature of the soil and the interception of area -wide surface runoff by the storm
system in S. 160th Street above the site.
Seismic induced liquefaction is not an issue in that the soils cannot be saturated with free
water due their permeability and hillside topography. The uniform particulate sands /silts
are present in the soils, but with the soils not liable to saturation, per above comment,
liquefaction cannot occur, even during significant seismic events.
A bearing pressure of 2,000 PSF on undisturbed soils should be used for foundation
design.
All water from impervious surfaces, including the three new residences and private road,
should be collected and disposed of using infiltration systems. Based on proposed
impervious surface areas, the KCSWM Appendix "C" could be used to design and size
required infiltration system.
Conclusion:
Based on the above, the sloped hillside, if not devegetated or disturbed by earthwork,
present little or no risk to the use of the area above them for residential use. It is
recommended that a specific geotechnical report be prepared to support the building
permit for Lot 4 when specifics of building size, layout and location are determined. This
requirement should be recorded on the short plat for future reference to the owner of the
Lot 4.
Engineer's Note:
Please note that while the above reflects a careful and researched review of the site, the
Engineer cannot be held responsible for irregular sub - surface conditions not evident from
the surface or exposed soils, from effects of unusually severe weather, from improper
construction, or from failure to follow the above recommendations or those from other
sources.
Should questions arise concerning this evaluation, please contact this office.

limitations for timber production except droughtiness,
which increases seedling mortality.
This soil can support high density housing units and
onsite sewage disposal systems. The soil is easily ex-
cavated. However, trenches for utility lines need to be
shored up as a safety precaution. Capability subclass IVs.
18C— Indianola loamy sand, 6 to 15 percent slopes.
This rolling soil is somewhat excessively drained. It
formed in sandy glacial outwash on broad uplands. The
vegetation is conifers. Elevation ranges from 200 and 800
feet. The annual precipitation averages about 35 inches.
Annual air temperature averages about 50 degrees F, and
the frost -free season averages about 180 days. This soil is
adjacent to areas of a soil that has a hardpan at a depth
of about 3 feet and to areas of a soil that is deep, loose,
and gravelly. Some areas of this soil, particularly along
Puget Sound, rest upon unstable lake sediments. Areas
average about 35 acres in size.
Included with this soil in mapping are about 10 percent
Alderwood, Everett, and Kitsap soils. A small percentage
of Ragnar fine sandy loam is included.
In a typical profile the surface layer, 7 inches thick, is
dark brown loamy sand. The underlying material, to a
depth of more than 60 inches, is dark yellowish brown,
brown, or olive brown sand. Reaction is slightly acid and
medium acid.
Permeability is rapid. The available water capacity is
low to moderate. Surface runoff is medium, and the ero-
sion hazard is moderate. Roots extend to a depth of more
than 60 inches.
Because this soil is suitable for onsite sewage disposal
systems, much of it is being converted to urban uses in
the rural areas. The remainder is cultivated or in
woodland. Hay and pasture are the chief crops. Strawber-
ries and cane fruit, principally raspberries, are the minor
crops.
This soil is moderately productive. Practices that main-
tain tilth and fertility and reduce erosion are necessary.
Grasses seeded in bare areas protect the soil during the
rainy season. Prevention of overgrazing, weed control,
and supplemental irrigation help to maximize forage
yields.
The organic matter content can be maintained by using
all crop residue, adding barnyard manure, plowing under
cover crops, and using a suitable cropping system.. An ex-
ample of a suitable system consists of orchardgrass and
white clover for 5 or 6 years followed by oats for 1 year
or strawberries for 3 years.,
Most crops respond to nitrogen, phosphorus, and potas-
sium. Legumes benefit from applications of agricultural
lime.
This soil is suited to the production of Douglas -fir. It is
capable of producing annually 135 cubic feet (CMAI), or
570 board feet (Scribner rule), per acre. This soil has few
limitations for timber production except droughtiness,
which increases seedling mortality.
This soil can support high density housing units and
onsite sewage disposal systems. The soil is easily ex-

cavated. However, trenches for utility lines need to be
shored up as a safety precaution. Bare soil areas erode
unl s seeded to a cover crop. Capability subclass IVe.
Indianola loamy sand, 15 to 45 percent slopes.
This moderately steep to steep soil is somewhat exces-
sively drained. It formed in sandy glacial outwash on
broad uplands and in drainageways. The average slope of
this soil is about 20 percent. Elevation ranges from 200 to
800 feet. The vegetation is conifers. The annual precipita-
tion averages about 35 inches, annual air temperature
averages about 50 degrees F, and the frost -free season
averages about 180 days. In drainageways this soil is ad-
jacent to or above unstable Kitsap soil.
Included with this soil in mapping are as much as 10
percent Alderwood and Kitsap soils and small acreages of
Neilton soils and other less sloping Indianola soils.
In a typical profile the surface layer is dark brown
loamy sand about 5 inches thick. The underlying material,
to a depth of more than 60 inches, is dark yellowish
brown, brown, or olive brown sand. Reaction is slightly
acid and medium acid.
Permeability is rapid. The available water capacity is
low to moderate. Surface runoff is medium to rapid, and
the erosion hazard is moderate to severe. Roots extend to
a depth of more than 60 inches.
Most areas of this soil are covered by trees or are in
wild pasture. Some less sloping areas have been ur-
banized.
This soil is suited to the production of Douglas -fir. It is
capable of producing annually 135 cubic feet (CMAI), or
570 board feet (Scribner rule), per acre. Bare soil areas
erode easily. Soil losses are minimized by diverting runoff
from skid trails and roads. Hand planting of Douglas -fir
in this sandy soil is preferable to aerial seeding.
The limitation for homesites is the moderately steep to
steep slopes. Deep cuts made during road construction,
particularly on the steep slopes, may expose unstable soil
material. A site preparation system that controls runoff
and maintains the esthetic value is needed. Capability
subclass VIe.
19B— Kapowsin gravelly loam, 0 to 6 percent slopes.
This nearly level to undulating soil is moderately well
drained. It formed in glacial till under conifers, and it
dominates the uplands .south of Graham and in the
Midland - Parkland area. Elevation ranges from 300 to 900
feet. The annual precipitation is 35 to 45 inches, mean an-
nual air temperature is about 50 degrees F, and the frost -
free season is about 180 days. Areas range from 50 acres
to more than 1,000 acres.
Included with this soil in mapping are as much as 10
percent Alderwood gravelly sandy loam and about 8 per-
cent very poorly drained Dupont and Tisch soils in basins
or depressions. As much as 10 percent poorly drained Bel-
lingham and McKenna soils in long, narrow depressions
and 5 percent excessively drained Neilton soils are also
included.
In a typical profile the surface layer is dark brown
gravelly loam to a depth of 7 inches. The subsoil, between

Subject: Request for Exception to Code, March- MacDonald, Inc. 4 -Lot Short Plat, 4404
South 160th Street (Tax ID# 810860050105) (L01 -019)
Request an exception to code relating to private road length for the above proposed short
plat. This request is based on criteria in TMC 17.28.010. The parcel, with dimensions of
90 feet by 633 feet, was originally investigated for sub - division into six lots as a short
sub - division. The requirement to provide a full width public road north through the entire
length of the property made this requirement impossible to comply with and killed this
concept (copy attached).
A revised 4 -lot short plat has been prepared (copy attached), with a functionally designed
20 foot wide private road serving the three new lots. The length required to serve the site
is approximately 275 feet. Prior to initiating the short plat, the conceptual approval from
both Highline Water District and the City Fire Department was obtained to place a new
fire hydrant within the property at the location of the hammerhead turnaround (approxi-
mately the 200 foot distance from the right -of -way line) (copy attached).
Based purely upon land area and zoning, the site could have six total lots. The reduction
from six potential lots to four lots greatly reduces the ability of the owners to econom-
ically provide new building lots to the community. If the requirement to limit the road
length to 200 feet is required in this case, the possible number of new lots would be only
two. The short plat would not be economically feasible for only two additional lots, and
the short plat would have be withdrawn from City consideration.
With the proposed 4 -lot short plat, the rear "residual" Lot 4 has an area of 29,430 SF, far
in excess of the zoning minimum of 7,200 SF. If Lot 3 had to be eliminated to meet road
criteria, the rear lot (the new Lot 3) would grow to 38,800 SF for a single lot, or nearly an
acre, which is not wise or economical land use.
We are convinced that with the 20 foot roadway width, the provided standard turnaround,
and the installation of a new fire hydrant on a main extension towards the rear of the

RE: L01 -019
Sunnydale Gardens Short Plat
Dear Mr. MacVeigh,
Based upon your March 9 submittal the City has the following comments on your short
plat:
1. The proposed road exceeds the 200 foot length allowed for private access roads.
You will need to either revise the design to meet the minimum standards for a public
road or apply to the Short Subdivision Committee for an exception from the
standard based on the criteria and procedures at TMC 17.28.010.
2. The private access road easement should not be a separate tract, but should cross
over the individual parcels. It should also extend to the southernmost boundary of
Lot 4.
3. The existing garage cannot remain on Lot 2 on its own because a garage must be
accessory to a house on the same lot. You may either demolish the garage after
obtaining a permit from the City (contact Jim Dunaway at 206 - 431 -3670) or prior to
final approval post a bond for 150% of the cost of demolition if a new house will be
built on the lot within one year. If the new house is not built by that deadline the
owner must agree to let the City demolish the garage at the owner's expense.
4. Please discuss the issue of the proposed private hydrant with Steve Kohler in the
Tukwila Fire Department (206) 575 -4404.
5. See attached comments from the Public Works Department.

The City Of Tukwila Public Works Department has the following comments
regarding your application for the above permit. Please contact Jill Mosqueda at
(206) 433 -0179, if you have any questions regarding the following comments.
The Public Works preapplication comments are attached. If you need additional
enclosures as listed on the bottom of the second page, please request those
from the Public Works Permit Technician.
General Comment
1. The submittal is missing the geotechnical report and the percolation tests.
The geotechnical report analysis could affect the lot configuration. The
analysis shall include specific foundation requirements, including drainage.
The percolation tests and any infiltration should be per lot.
2. Public Works wants to see approval from Highline Water District for crossing
the sanitary sewer and the water supply lines at the main and within the
short plat.
3. The access road is longer than 200' and therefore, qualifies as a public road,
requiring improvements per the code. I believe you may be successful, in
this case, if you apply for an exception to the code. If you are successful, the
City will still require drainage for the roadway.
Plat Map
The plat shows Lots 1 -4. One of the notes gives the proposed lot sizes and all
the lots are listed as lot 1.

Dear Mr. MacDonald,
w
AMEC Earth & Environmental, Inc. (AMEC) is pleased to submit this report presenting our z �.
geotechnical evaluation for the above - referenced project. The purpose of our evaluation is to o
derive conclusions and recommendations concerning site preparation, foundations, bearing
pressure, liquefaction, lateral earth pressures, slab -on -grade floors, slope stability, and
drainage characteristics for the proposed four -lot plat in Tukwila, Washington. o
As outlined in our proposal letter dated December 10, 2001 (T- 2193 -0), our scope of work 0
consists of field exploration, geotechnical research, engineering analysis, limited laboratory LL p
analysis, and report preparation. We received your written authorization for our evaluation on w z
December 12, 2001. As requested, we reviewed the initial geotechnical evaluation prepared by o
t=-
Bruce MacVeigh P.E. dated August 6, 2002 and began this portion of the study on January 23, o 1—
2002. This report has been prepared for the exclusive use of you and your consultants, for z
specific application to this project, in accordance with generally accepted geotechnical
engineering practice.
1.0 SITE AND PROJECT DESCRIPTION
The project site consists of an existing single - family home with associated parking and a
currently undeveloped portion of the subject property north of the existing home. The project
site is located at 4404 - 160` Street, Tukwila, Washington as shown in the attached Location
Map (Figure 1). Proposed Lots 1, 2, & 3 slope downward to the north with an approximate
inclination of about 5 to 7 percent (measured in field) and proposed Lot 4 gradually steepens its
downward slope to the northwest and develops a maximum inclination of about 45 percent
(measured in field) throughout the northernmost portion of the property. Site boundaries are
generally delineated by a slope to the north, residential property to the east and west, and by
160 Street to the south. The enclosed Site & Exploration Plan (Figure 2) illustrates these site
boundaries, adjacent existing features, and proposed home locations.

We understand that development plans call for subdividing the existing lot into four
smaller residential Tots. Lot 1 is to contain the existing home and new single - family
residential, structures are to be constructed on lots 2, 3, and 4. The home currently
proposed for Lot 4 is to be located along the southern portion of the proposed lot, and
upslope of the steep grade of the lot. The area surrounding the homes will be paved for
parking and vehicle access or landscaped.
2.0 EXPLORATORY METHODS
During our initial involvement with this project AMEC observed the surface conditions of
the project on November 9, 2001. We then explored surface and subsurface conditions
at the project site on January 24, 2002. Our exploration and testing program comprised
the following elements:
• A visual surface reconnaissance of the site;
• Three Test Pits (designated TP -1 through TP -3), advanced at strategic
locations across the site;
• A review of published geologic and seismologic maps and literature.
Table 1 summarizes the approximate functional locations, and termination depths of our
subsurface explorations, and Figure 2 depicts their approximate relative locations. The
following text section describes our procedures used for test pits.
The specific number, locations, and depths of our explorations were selected in relation
to the proposed site features, under the constraints of surface access and budget
considerations. We estimated the relative location of each exploration by measuring
from existing features and scaling these measurements onto a layout plan supplied to
us by you. Consequently, the data listed in Table 1 and the locations depicted on
Figure 2 should be considered accurate only to the degree permitted by our data
sources and implied by our measuring methods. These field measurements are
intended to provide the general relationship of on -site features and should not be
considered a field survey of any type.

It should be realized that the explorations performed for this evaluation reveal
subsurface conditions only at discrete locations across the project site and that actual
geologic conditions in other areas may vary. Furthermore, the nature and extent of any
such variations would not become evident until additional explorations are performed or
until construction activities have exposed them. If significant variations are observed at
that time, AMEC may need to modify the conclusions and recommendations contained
in this report to reflect the actual site conditions.
2.1 Test Pit Procedures
Our exploratory test pits were excavated with a tire- mounted backhoe operated by an
independent firm working under subcontract to AMEC. A geotechnical engineer from
our firm continuously observed the test pit excavations and logged the subsurface
conditions. After describing each test pit, the backhoe operator backfilled each test pit
with excavated soils and tamped the surface.
In our opinion, exploration soil pits are the preferred method of subsurface exploration
for this project. Test pits, which are 8 to 12 feet in length, provide a continuous, broad,
and more detailed exposure of near - surface soil conditions than typically provided by 2-
inch- diameter split spoon samplers, which provide samples at 2%2- to 5 -foot intervals
and are extremely narrow in range. This is particularly important in landslide areas,
where narrow slip planes can often go undetected by auger borings.
The enclosed Test Pit Logs indicate the vertical sequence of soils and materials
encountered in each test pit. Where a soil contact was observed to be gradational or
undulating, our logs indicate the average contact depth. Our representatives
continuously monitored the explorations; visually classified the soils encountered, and
maintained logs of the subsurface conditions. The soils were classified in the field in
general accordance with the system described on Figure 7. We estimated the relative
density and consistency of the in -situ soils by means of the excavation characteristics
and the stability of the test pit'sidewalls. Our logs also indicate the approximate depths
of any sidewall caving or groundwater seepage observed in the test pits, as well as all
sample numbers and sampling locations.
3.0 SITE CONDITIONS
The following sections of text present our observations, measurements, findings, and
interpretations regarding surface, soil, groundwater, and seismic conditions at the
project site.
3.1 Surface Conditions
The project site consists of an existing single - family home with associated parking and a
currently undeveloped portion of the subject property north of the existing home. We
understand that current development plans call for subdividing the existing lot into four
smaller residential lots. Proposed Lot #1 provides vehicle access to proposed lots 2, 3,
and 4, it also contains the existing home. Proposed lots 1, 2, & 3 slope downward to the
north with an approximate inclination of about 5 to 7 percent (measured in field) and

proposed lot 4 gradually steepens its downward slope to the northwest and develops a
maximum inclination of about 45 percent (measured in field) throughout the
northernmost portion of the property.
The project site is vegetated by cut grass, mature Douglas Fir, Alder, and Maple trees.
In areas that are not currently landscaped the under -story consists of moderately thick
groundcover including laurel and berry vines or bushes. No indication of past slope
instability, seeps, springs, or geologic contacts were observed within or adjacent to the
subject property.
3.2.1 'Published Geology
According to published geologic maps, the site is located within the Puget Lowland.
Quaternary sediments consisting of various glacial, fluvial, lake and marsh deposits
dominate the region. These sediments were deposited from the Puget Lobe of the
Cordilleran continental ice sheet during the Vashon Stade of the Fraser Glaciation.
The geologic map entitled "Geology of the Des Moines Quadrangle, Washington"
prepared by Howard H. Waldron, Figure 3 (Geologic Mapping), classifies the soils in the
vicinity of the project site as ground moraine (Qgt), which are characterized as mainly
compacted unoxidized glacial till. The "Slope Map of Part of West - Central King County,
Washington" prepared by the U.S. Geological Survey 1975, Figure 4 (Slope Map),
indicates that the slopes in the vicinity of the project site are gentle to moderate with a
maximum inclination of about 15 percent.
The "Map Showing Relative Slope Stability in Part of West - Central King County,
Washington" prepared by Robert D. Miller, Figure 5 (Slope Stability Map), classifies the
slopes in the vicinity of the project site as Class 1. These slopes are generally stable
even where modified by man. Sections of the proposed property may extend into a
region classified as Class 2. Class 2 slopes are normally stable but may become
unstable due to man's activities. It is our understanding that although the property may
contain Class 2 slopes, no development is planned in these areas.
The "Map Showing Relative Compressibility of Earth Materials in Part of West - Central
King County, Washington" prepared by Robert D. Miller, Figure 6 (Soil Compressibility
Map), classifies the soil in the vicinity of the project site as Class lia. Class Ila soils are
virtually non - compressible to slightly compressible consisting of course to fine- grained,
dense materials.
3.2.2 Observed Soil Conditions
Our explorations revealed sandy soils of varying density, and generally diverged fro the
published geological mapping. Specifically, our on -site explorations revealed
approximately 6 inches of loose organic soil overlying about 2 feet of loose, moist, silty
sand with roots. Beneath the silty sand, we encountered about 21/2 to 7A feet of sand

with trace silt and gravel. The sand continued to the termination of our test pits. In test
pit TP -2, we encountered a 1 -foot layer of medium dense, moist, silty, gravelly sand
beneath the silty sand before encountering the sand. A previous geotechnical
evaluation, prepared by Bruce S. MacVeigh, P.E. indicates, "a clay loam layer was
found at a depth of 3%2 -feet in only one hole and appears to be an anomaly." This soil
layer was not encountered during our subsurface exploration program.
3.3 Groundwater Conditions
At the time of our excavations (January 24, 2002), groundwater was not encountered
within the depths of our test pits. Because our explorations were performed during a
period . of wet weather, and during a period experiencing near normal precipitation
patterns, these observed groundwater conditions may closely represent the yearly
average levels. At all times of the year, groundwater levels would likely fluctuate in
response to precipitation patterns, off -site construction activities, and site utilization.
3_4 Seismic Conditions
Based on our analysis of the subsurface explorations and our review of published
geologic maps, we interpret the on -site soil conditions to correspond to a seismic soil
profile type S as defined by Table 16 -J of the 1997 Uniform Building Code. Current
(1996) National Seismic Hazard Maps prepared by the U.S. Geological Survey indicate
that a bedrock site acceleration coefficient of about 0.31 is appropriate for an
earthquake having a 10- percent probability of exceedance in 50 years (corresponding to
a return interval of 475 years). According to Figure 16 -2 of the 1997 Uniform Building
Code, the site lies within seismic risk zone 3.

4.0 CONCLUSIONS AND RECOMMENDATIONS
Development plans call for sub - dividing the existing lot into 4 smaller residential Tots.
We offer the following general geotechnical conclusions and recommendations
concerning this project.
• Feasibility: Based on our field explorations, research, and analyses, the
proposed development appears feasible from a geotechnical standpoint,
contingent on proper design and construction.
• Foundation Options: In our opinion, conventional spread footings will
provide adequate support for the proposed homes if the subgrades are
properly prepared. Due to the inclination of the currently proposed Lot 4,
a daylight basement with conventional spread footings will also provide
adequate support for the proposed structure if subgrade walls are
properly deigned and constructed and the subgrades are properly
prepared.
• Buffers and Setbacks: In our opinion no buffer or set back from the slope
on lot 4 is required to mitigate potential slope instability. However, the
City of Tukwila as well as King County may require setbacks for other
purposes such as stormwater infiltration and sanitary septic drain fields.
• Seismic Considerations: Based on our literature review and subsurface
interpretations, we recommend that the project structural engineer use
the following seismic parameters for design of buildings, retaining walls,
and other site structures:
Design Parameter Value
Acceleration Coefficient (USGS) 0.30
Risk Zone (UBC) 3
Soil Profile Type (UBC) Sp

• On -Site Soil Reuse: The surficial sod, duff, topsoil, and organic -rich soils
mantling most of the project site are not suitable for use as structural fill
under any circumstances, due to their high organic content. The
underlying soils consisting of silty sand (SM) appear to be suitable for use
as structural fill in their current moisture condition.

The following text sections of this report present our specific geotechnical conclusions
and recommendations concerning site preparation, foundation design, slab -on -grade
floor, pavement design and structural fill.
4_1 Slope Stability Analysis
Based on visual observations, field- testing, empirical correlations, and experience with
similar soil types, it is our opinion that all of the proposed building areas are grossly
stable with respect to deep- seated failure. In our opinion, no further slope analysis will
be required if the homes are placed in the locations depicted in figure 2 (Site and
Exploration Plan).
4_2 Buffer and Setbacks
In our opinion, no buffer or setback from the slope located on lot 4 is required to mitigate
potential slope instability. However, the city of Tukwila, as well as King County, may
require setbacks for other purposes such as stormwater infiltration and sanitary septic
drain fields. Nonetheless, surface water runoff should be controlled and prevented from
flowing onto or over the slope. The surface vegetation should be maintained by the
homeowner to prevent erosion of the surface soil.
4 Site Preparation
Preparation of the project site should involve clearing, stripping, and subgrade
compaction. The paragraphs below discuss our geotechnical comments and
recommendations concerning site preparation.
Erosion Control: Before construction begins an appropriate erosion control system
should be installed. This system should collect and filter all surface run off through
either silt fencing or a series of properly placed and secured straw bales. We anticipate
a system of berms and drainage ditches will provide an adequate collection system. If
silt fencing is selected as the silt filter the fencing fabric should meet the requirements of
WSDOT Standard Specification 9 -33.2 Table 3. The silt fence should be buried so that
sediment cannot pass beneath it. If straw bails are used as the silt filter, the bales
should be secured to the ground such that they will not shift under the weight of any
water retained. Regardless of the sediment filter selected, it should be inspected and
maintained during the time that the site soils are exposed, on a periodic basis and after
any major rainstorm event. Specifically, holes in the filter and areas where the filter has
shifted above ground surface should be repaired as soon as they are identified.

Because stripped surfaces and soil stockpiles are typically a source of runoff sediments,
they should be given particular attention. If earthwork occurs during wet weather, we
recommend that all stripped surfaces be covered with straw to reduce the runoff
erosion. Similarly soil stockpiles and cut slopes should be covered with plastic sheeting
for erosion protection
Clearing and Stripping: The construction areas should be cleared and stripped of all
grass, sod, topsoil, trees, wood, miscellaneous debris, and fill. Our explorations indicate
that an average thickness of about 6 inches of soft organic soil will be encountered
across most of the site, but slight variations in thickness may be encountered when
excavation begins.
Filling: Any holes created by the stripping operation should be filled with properly
compacted structural fill, such as "pit run" or "gravel borrow." Regardless of soil type, all
fill should be placed and compacted according to our recommendations presented in the
Structural Fill section of this report. ,
Temporary Cut Slopes: All temporary soil cuts associated with site regrading or
excavations should be adequately back sloped to prevent sloughing and collapse.
Based on our explorations, silty sand soils will likely be exposed in on -site cuts. Based
on this we recommend that temporary slopes be constructed at 1 %2H:1 V. However,
flatter slopes may be necessary if the actual soil conditions exposed in the cuts require
it. Nonetheless, the contractor should assess the conditions of the excavation before a
final determination of the appropriate slope inclination has been made.
Subgrade Compaction: We recommend that exposed subgrades for footings, floors,
pavements, and other structures be proof rolled or compacted to a dense ' condition.
Any localized zones of loose granular soils observed within a subgrade should be
compacted to a density commensurate with the surrounding soils. Any organic, soft, or
pumping soils observed within a subgrade should be overexcavated and replaced with
structural fill.
Wet - Weather Considerations: Most of the on -site soils are expected to be relatively
resistant to minor variations in moisture content and may be suitable for reuse as
structural fill during wet weather. However, undisturbed native soils that are exposed to
excessive moisture water for an extended period of time may become unsuitable for use
as structural support. In our opinion, the project specifications should include provisions
for using imported; clean, granular fill in case the on -site soils become too wet and filling
must proceed during wet weather. To reduce the potential need for importing clean
granular fill, we recommend scheduling construction for periods of extended dry
weather, as may occur during the summer months. Project specifications should also
include provisions for using quarry spalls to protect high traffic areas as deemed
appropriate by the contractor.

4_4 Foundations
In our opinion, conventional spread footings will provide adequate support for the
proposed structures if the subgrades are properly prepared. Due to the inclination of the
currently proposed Lot 4 a daylight basement with conventional spread footings will also
provide adequate support for the proposed structure if subgrade walls are properly
deigned and constructed and the subgrades are properly prepared. We offer the
following comments and recommendations for purposes of footing design and
construction.
Footing Subgrades: In order to provide adequate bearing conditions for spread footings,
all subgrades for the buildings should consist of a minimum of 12 inches of firm and
unyielding native soil or compacted structural fill per the Structural Fill section of this
report. Any existing organic -rich soils should be overexcavated to expose the
underlying silty sand.
Subgrade Observation: All footing subgrades should consist of firm, unyielding, native
soils or structural fill materials. Footings should never be cast atop loose, soft, frozen
soil, sloughed soils, debris, existing uncontrolled fill, or surfaces covered by standing
water. We recommend that an AMEC representative observe the condition of all
subgrades before any concrete is placed.
Footing Backftll: To provide erosion protection and lateral Toad resistance, we
recommend that all footing excavations be backfilled on both sides of the footings after
the concrete has cured. Either imported structural fill or non - organic on -site soils can be
used for this purpose, contingent on suitable moisture content at the time of placement.
Regardless of soil type, all footing backftll soil should be compacted to a density of at
least 90 percent (based on ASTM D- 1557).
Spread Footings: In our opinion, footings that bear on properly prepared subgrades can
be designed for a maximum allowable soil bearing pressure 2,000 pounds per square
foot (psf) for compacted structural fill or native soils. This bearing pressure applies to all
long term live and dead loads exclusive of the weight of the footing and any overlying
backftll, and may be increased by one -third to include short-term loads such as wind or
seismic influence. If larger bearing capacities are required, please contact our office for
more information.
For frost and erosion protection, the base of all exterior footings should bear at least
18 inches below adjacent outside grades, whereas the base of interior footings need
bear only 12 inches below the surrounding slab surface level. Continuous (wall) and
isolated (column) footings should be at least 18 and 24 inches wide, respectively. We
recommend that any disturbed soils in the footing excavations be removed or, if
practical, recompacted prior to concrete placement. To ensure the adequacy of bearing
surfaces, all footing excavations should be observed by an AMEC representative prior to
placing concrete.

Lateral Resistance: Footings that have been properly backfilled as recommended
above will resist lateral movements by means of passive earth pressure and base
friction. We recommend using an allowable passive earth pressure of 250 pcf
(equivalent fluid weight) and an allowable base friction coefficient of 0.35.

recommendations. o

Subgrade Conditions and Observation: All soil- supported slab -on -grade floors should 2
bear on firm, unyielding native soils or on suitable structural fill soils. We recommend
that an AMEC representative observe the condition of all slab- supporting soils before o !
any fill or concrete is placed. w w

1— L
Capillary Break: To retard the upward wicking of groundwater beneath the floor slabs, t — o
we recommend that a capillary break be placed over the subgrade. Ideally, this capillary
o
break would consist of a 4- inch -thick layer of pea gravel or other clean, uniform, well- o '—
rounded gravel, such as "Gravel Backfill for Drains" per WSDOT Standard Specification z
9- 03.12(4). Alternatively, angular gravel or crushed rock can be used if it is sufficiently
clean and uniform to prevent capillary wicking.
Footing Settlements: We estimate that total post- construction settlements of properly
designed footings bearing on properly prepared subgrades will not exceed 1 inch.
Differential settlements should not exceed one -half of the actual total settlement
between adjacent, equally loaded, foundation elements. These settlements would be
reduced if the actual design bearing pressures are lower than our recommended
maximum pressures.
Vapor Barrier: We recommend that a layer of durable plastic sheeting (such as
Crosstuff, Moistop, or Visqueen) be placed directly between the capillary break and the
floor slab to prevent ground moisture vapors from migrating upward through the slab.
During subsequent casting of the concrete slab, the contractor should exercise care to
avoid puncturing this vapor barrier.
Curing Course: A "curing course" is a thin layer (typically 2 inches thick) of clean sand
that is sometimes placed over the vapor barrier to facilitate uniform curing of the
overlying concrete slab. Recent studies, however, have indicated that this course is not
necessary when moderately strong concrete is used for the slab. Consequently, we
recommend that the project structural engineer be allowed to decide whether a curing
course should be used.

Vertical Deflections: Soil- supported slab -on -grade floors can deflect downward when
vertical loads are applied, due to elastic compression of the subgrade. In our opinion, a
subgrade reaction modulus of 250 pounds per cubic inch can be used to estimate such
deflections.
4_6 Subgrade Walls:
The required strength of a subgrade wall depends on the nature, density, and
configuration of the soil behind the wall and the amount of lateral wall movement which
can occur after construction has been completed. Subgrade walls are also significantly
effected by the buildup of water behind a retaining wall, thus we recommend all walls be
backfilled and drained as discussed below.
Applied Soil Pressure: Walls that are designed to move 0.1 percent of the wall height
during and after construction are usually referred to as unrestrained walls. We
recommend that unrestrained subgrade walls supporting natural slopes inclined at
2H:1V or flatter be designed to resist an active pressure (triangular distribution) of
35 pounds per cubic foot (pcf). The recommended pressure does not include the effects
of surcharges from surface loads hydrostatic pressures, or structural loads. If such
surcharges are to apply, they should be added to the above design lateral pressures.
Wall Foundations: Subgrade walls can be supported on shallow footings bearing on
suitable soils as described in the Spread Footings section of this report. Footings
should be designed using the recommended allowable bearing pressures and lateral
resistance values presented for building foundations when the adjacent downhill slope is
3H:1 V (horizontal: vertical) or flatter.
Wall Drainage: Groundwater drainage should be provided behind concrete walls by
placing a zone of sand and gravel containing Tess than 3 percent fines (material passing
No. 200 sieve) against the wall. This drainage zone should be at least 24 inches thick
(measured horizontally) and extend from the base of the wall to within 1 foot of the
finished grade behind the wall, and capped as recommended below. Smooth - walled
perforated PVC drainpipe having a minimum diameter of 4 inches should be embedded
within the sand and gravel at the base of the wall along its entire length. This drainpipe
should discharge into a tightline leading to an appropriate collection and disposal
system.
Backfill Compaction: Because soil compactors place significant lateral pressures on
subgrade walls, we recommend that only small, hand - operated compaction equipment
be used within 2 feet of a backfilled wall. Also, all backfill should be compacted to a
density as close as possible to 90 percent of the maximum dry density (based on
ASTM:D- 1557); a greater degree of compaction closely behind the wall would increase
the lateral earth pressure, whereas a lesser degree of compaction might lead to
excessive post- construction settlements.

ame
Grading and Capping: To retard the infiltration of surface water into the backfill soils, we
recommend that the backfill surface of exterior walls be adequately sloped to drain away
from the wall. Ideally, the backfill surface directly behind the wall would be capped with
asphalt, concrete, or 12 inches of low- permeability (silty) soils to minimize or preclude
surface water infiltration. If low - permeability (silty) soils are selected, as the capping
material a geotextile should be paced over the drainage material; typical silt fencing is
appropriate of this purpose.
Wall Settlements: We estimate that the settlement of the wall footings will be on the
order of 1 inch or less. Most of this settlement is expected to occur as soon as the
Toads are applied. Differential settlement along the walls is expected to be 1 inch or less
over a 50 -foot span.
4 Drainage Systems
In our opinion, the building should be provided with permanent drainage systems to
reduce the risk of future moisture problems. We offer the following recommendations
and comments for drainage design and construction purposes.
Runoff Water: Roof -runoff and surface -runoff water should not be discharged on the
slope. Instead, runoff water should discharge into separate tightline pipes and be routed
away from the building to a storm drain or other appropriate location approved by the
City of Tukwila and /or King County.
Grading and Capping: Final site grades should slope downward away from the building
and the slope on proposed Lot 4 so that runoff water will flow by gravity to suitable
collection points, rather than ponding near the building, or sheet flowing over the face of
the slope. Ideally, the area surrounding the building would be capped with concrete,
asphalt, or low- permeability (silty) soils to reduce or preclude surface -water infiltration.
4.8 Structural Fill
The term "structural fill" refers to any materials placed under foundations, retaining
walls, slab -on -grade floors, sidewalks, pavements, and other structures. Our
comments, conclusions, and recommendations concerning structural fill are presented
in the following paragraphs.
Materials: Typical structural fill materials include clean sand, gravel, pea gravel, washed
rock, crushed rock, quarry spalls, controlled - density fill (CDF), lean -mix concrete (LMC),
well - graded mixtures of sand and gravel (commonly called "gravel borrow" or "pit- run "),
and miscellaneous mixtures of silt, sand, and gravel. Recycled asphalt, concrete, and
glass, which are derived from pulverizing the parent materials, are also potentially useful
as structural fill in certain applications, however the contractor should contact the local
regulatory authority for environmental restrictions should recycled materials be utilized
on the project site. Soils used for structural fill should not contain any organic matter or
debris, or any individual particles greater than about 4 inches in diameter.

On -Site Soils: Because moderate cuts are planned for the project, we expect that
moderate quantities of on -site soils will be generated during earthwork activities.
Therefore, we offer the following evaluation of these on -site soils in relation to potential
use as structural fill.
Surficial Organic Soils: The sod, duff, topsoil, and organic -rich soils mantling
portions of the site are not suitable for use as structural fill under any
circumstances, due to their high organic content. Consequently, these materials
can be used only for non - structural purposes, such as in landscaping areas.
Clay Loam: No specific information about the "clay loam layer" reported in the
geotechnical evaluation prepared by Bruce S. MacVeigh was available at the
time of our study. Nonetheless, based on our experience with fine grained soils
we recommend that "clay loam" soils not be utilized as structural fill unless
approved by an AMEC representative.
Sands: The silty sands underlying the surficial organic soils appear suitable for
reuse as structural fill at their present moisture contents. These soils will provide
a favorable source of fill soils that can be used in a broad range of weather
conditions, although aeration or sprinkling might be needed to achieve an
optimum moisture content during especially wet or dry conditions, respectively.
Fill Placement: Generally, pea gravel, washed rock, quarry spalls, CDF, and LMC do
not require special placement and compaction procedures. In contrast, clean sand,
gravel, crushed rock, soil mixtures, and recycled materials should be placed in
horizontal lifts not exceeding 8 inches in loose thickness, and each lift should be
thoroughly compacted with a mechanical compactor.
Subgrade Observation and Compaction Testing: Regardless of material or location, all
structural fill should be placed over firm, unyielding subgrades prepared in accordance
with the Site Preparation section of this report. An AMEC representative before should
observe the condition of all subgrades before filling and /or construction begins. Also, fill
soil compaction should be verified by means of in -place density tests performed during
fill placement so that adequacy of soil compaction efforts may be evaluated as
earthwork progresses.
Compaction Criteria: Using the Modified Proctor test (ASTM:D -1557) as a standard, we
recommend that structural fill used for various on -site applications be compacted to the
following minimum densities:

Soil Moisture Considerations: The suitability of soils used for structural fill depends
primarily on their grain -size distribution and moisture content when they are placed. As
the "fines" content (that soil fraction passing the U.S. No. 200 Sieve) increases, soils
become more sensitive to small changes in moisture content. Soils containing more
than about 5 percent fines (by weight) cannot be consistently compacted to a firm,
unyielding condition when the moisture content is more than two percentage points
above or below optimum. For fill placement during wet - weather site work, we
recommend using "clean" fill, which refers to soils that have a fines content of 5 percent
or less (by weight) based on the soil fraction passing the U.S. No. 4 Sieve.
CDF Strength Considerations: CDF is normally specified in terms of its compressive
strength, which typically ranges from 50 to 200 psi. CDF having a strength of 50 psi
(7,200 psf) provides adequate support for most structural applications and can be
readily excavated with hand shovels. A strength of 100 psi (14,400 psf) provides
additional support for special applications but greatly increases the difficulty of hand -
excavation. CDF having a strength greater than about 100 psi requires power
equipment to excavate and, as such, should not be used where future hand - excavation
might be needed.

5.0 RECOMMENDED ADDITIONAL SERVICES
Because the future performance and integrity of the structural elements will depend
largely on proper site preparation, drainage, fill placement, and construction procedures;
monitoring and testing by experienced geotechnical personnel should be considered an
integral part of the construction process. Consequently, we recommend that AMEC be
retained to provide the following post -report services:
AMEC
• Review all construction plans and specifications to verify that our design
criteria presented in this report have been properly integrated into the
design;
• Prepare a letter summarizing geotechnical aspects of review comments
(if required by the City of Tukwila and /or King County);
• Observe all exposed subgrades after completion of stripping and
overexcavation to confirm that suitable soil conditions have been reached
and to determine appropriate subgrade compaction methods;
• Monitor the placement of all structural fill and test the compaction of
structural fill soils to observe their conformance with the construction
specifications;
• Probe all completed subgrades for footings and slab -on -grade floors
before concrete is poured, in order to verify their bearing capacity;
• Prepare a post- construction letter summarizing all field observations,
inspections, and test results (if required by the City of Tukwila and /or King
County);

6.0 CLOSURE
The conclusions and recommendations presented in this report are based, in part, on
the explorations that we performed for this study; therefore, if variations in the subgrade
conditions are observed at a later time, we may need to modify this report to reflect
those changes. Also, because the future performance and integrity of the project
elements depend largely on proper initial site preparation, drainage, and construction
procedures, monitoring and testing by experienced geotechnical personnel should be
considered an integral part of the construction process. AMEC is available to provide
geotechnical observation, soils and concrete testing, steel and masonry inspection, and
other services throughout construction.
We appreciate the opportunity to be of service on this project. If you have any questions
regarding this report or any aspects of the project, please feel free o • tact our office.
Sincerely,
AMEC Earth and Environmental, Inc.

NOTES:
1. Field classification is based on visual examination of soil in
general accordance with ASTM D2488 - 90.
2. Soil classification using laboratory tests is based on ASTM D-
2487
3. Description of soil density or consistency are based on
interretation of blow count data, visual appearance of soils,
and /or test data.
SOIL MOISTURE MODIFIERS:
Du- contains no moisture.
Damp- contains a slight amount of moisture; more than about 2
percentage points below optimum moisture content.
Moist contains a moderate amount of moisture; generally
within about 2 percentage points of the 'optimum moisture
content for a modified Proctor test; readily compacts when
squeezed.
Wet- contains a relatively large amount of porewater; more
than about 2 percentage points abouve optimum moisture
content.
Saturated- contains an excessive amount of porewater; soil has
zero air voids.
