Attention: Mr. Ralph Hagler
Dear Mr. Hagler:
Modular Block Wall Design
INS Seattle District Office
Tukwila International Boulevard
Tukwila, Washington
Established 1975
In accordance with your request, Earth Consultants, Inc. (ECI) has prepared this modular
block wall design for the proposed site development. We understand mechanically
stabilized earth (MSE) fills and modular block wall construction is being considered
throughout portions of the site. The modular block wall heights and MSE fills could be on
the order of ten (10) to twenty -six (26) feet in some areas. Our scope of services
included review of the grading plan prepared by David Evans and Associates, engineering
analysis, and preparation of the attached drawing. This design includes the attached
drawings with recommendations for construction of the MSE walls, as well as
recommendations for seven and one half foot and ten foot high gravity walls.
MSE and Modular Block Wall Design
The design calculations for the MSE Wall and gravity modular block walls are included in
Appendix A. The reinforcement schedule and recommendations for the wall construction
are presented on the attached sheets SM1 and SM2. The soil parameters used in the
design assume the reinforced fill soils will be compacted to the specified relative
compaction of 90 percent of the maximum dry density as determined by the Modified
Proctor Method (ASTM D- 1557 -91). The wall design assumes drainage is provided, and
that hydrostatic pressures will not be allowed to mobilize. Additional drainage other than
what is shown on the drawings may be necessary, depending on soil and groundwater
conditions observed at the time of construction. The drainage shown on the drawings is
a minimum requirement. The installation of sheet drain may be necessary along the
contact between native cut and the reinforced fill zone, if groundwater seepage
conditions are encountered. ECI should observe the MSE and modular block wall
construction on a full -time basis. Supplement recommendations for drainage will be
made by ECI, if necessary.

February 26, 2003
For the MSE and modular block wall construction, a traffic surcharge of two hundred fifty
(250) pounds per square foot (psf) was assumed. The design should be reevaluated by
ECI for other surcharge loading conditions, where applicable. For the gravity walls, traffic
surcharge loading was not included, assuming that the gravity walls will be constructed
above the driveway areas or in the vicinity of the storm water detention pond. If the
surcharge loading will apply to the gravity walls, ECI should reevaluate the design.
Global stability of the proposed walls and fill areas was assessed in the geotechnical
engineering study prepared by ECI (see Geotechnical Engineering Study E- 2579 -44, dated
February 20, 2003). Global stability was assessed for both static and seismic loading.
Adequate factors -of- safety were calculated for the static and seismic loading.
We trust this design meets your current needs, and the submittal requirements. If you
have any questions or need additional information, please contact us.
Sincerely,

RE: Permit Application No. D03 -345
12500 Tukwila International Boulevard
Dear Permit Holder:
In reviewing our current records the above noted permit has not received a final inspection by the City of Tukwila
Building Division. Per the Uniform Building Code and /or Uniform Mechanical Code, every permit issued by the
Building Official under the provisions of this code shall expire by limitation and become null and void if the
building or work authorized by such permit is not commenced within 180 days from the date of such permit, or if
the building or work authorized by such permit is suspended or abandoned at any time after the work is
commenced for a period of 180 days.
Based on the above, you are hereby advised to:
Sincerely,
Stefania Spencer
Permit Technician
Xc: Permit File No. D03 - 345
Bob Benedicto, Building Official
City of Tukwila
Department of Community Development Steve Lancaster, Director
• Call the City Of Tukwila Permit Center at (206) 431 -3670 to arrange for the next or final
inspection.
Steven M. Mullet, Mayor
This inspection is intended to determine if substantial work has been accomplished since issuance of the permit
or last inspection; or if the project should be considered abandoned.
If such determination is made, the Building Code does allow the Building Official to approve a one -time
extension up to 180 days. Extension requests must be in writing and provide satisfactory reasons why
circumstances beyond the applicants control have prevented action from being taken.
In the event you do not call for the above inspection or request and receive an extension prior to July 19, 2004,
your permit will become null and void and any further work on the project will require a new permit and
associated fees.
Thank you for your cooperation in this matter.

This letter is to inform you of corrections that must be addressed before your development permit(s) can
be approved. All correction requests from each department must be addressed at the same time and
reflected on your drawings. I have enclosed comments from the Public Works Department. At this time
the Fire, Planning and Building Departments have no comments.
Please address the attached comments in an itemized format with applicable revised plans,
specifications, and /or other documentation. The City requires that four (4) complete sets of revised
plans, specifications and /or other documentation be resubmitted with the appropriate revision
block.
In order to better expedite your resubmittal, a `revision sheet' must accompany every resubmittal. I have
enclosed one for your convenience. Corrections /revisions must be made in person and will not be
accepted through the mail or by a messenjier service.

the optimum level.
B. The maximum aggregate size shall be limited to 1 1/2 inches unless field tests have been
performed to evaluate potential strength reductions to the geogrid design due to damage
during construction.
C. Unsuitable soils for backfill (high plastic clays or organic soils) shall not be used in the
backfill or in the reinforced soil mass.
D. The fill material shall meet the following gradation:
fliegAiza Psrosnt Palling
1 1/2 inch 100 - 75
3/4 inch 100 -75
No. 40 0 - 60
No. 200 0 - 35
Fill that does not meet the above gradation must be approved by the geotechnical
engineer.
GEOGRID SOiL REINFORCEMENT
A. Geosynthetic reinforcement shall consist of geogrids manufactured specifically for soil
reinforcement applications and shall be manufactured from high tenacity polyester yam
or high density polyethylene. Polyester geogrid shall be knitted from high tenacity
polyester filament yam with a molecular weight exceeding 25,000 Meg/m and a carboxyl
end group values less than 30. Poyester geogrid shall be coated with an impregnated
PVC coating that resists peeling, cracking and stripping.
B. Geogrid long term design strength shall be at least 4,700 lbs./ft for walls 15.0 feet
or higher. For walls 12.5 feet or less, LiDS shall be at least 2,800 IbsJ'f. The contractor
shall provide manufacturers specifications to the geotechnical engineer for review
and approval.
C. Manufacturing Quality Control
The geogrid manufacturer shall have a manufacturing quality control program that
includes QC testing by an independent laboratory.
The QC testing shall include:
Tensile Strength Testing
Melt Flow Index (HDPE)
Molecular Weight (Polyester)
DRAINAGE PIPE
A. The drainage pipe shall be rigid perforated PVC pipe manufactured in accordance
with ASTM D -3034.
EXECUTION
EXCAVATION
A. Contractor shall excavate to the lines and grades shown on the construction drawings.
The geotechnical engineer shall observe the excavation and approve prior to placement
of leveling material or fill soils. Proof roll foundation area as recommended by the
geotechnical engineer to determine if remedial work is required.
B. Over -excavation and replacement of unsuitable foundation soils and replacement with
