Norpoint Heights Grading Exhibit, dated November 21, 2016
Dear Mr. Gibson:
In accordance with your request, Earth Solutions NW, LLC (ESNW) has
prepared this
geotechnical addendum letter for Lot 7 of the Norpoint Heights residential development.
Pertinent geotechnical recommendations are provided within this letter.
introduction
In preparation of our geotechnical addendum letter, ESNW reviewed the previously completed
geotechnical engineering study as well as performed a site visit to observe current conditions.
Based on our review, the majority of the geotechnical information provided within the
completed study is still applicable to current development plans. Additional pertinent
geotechnical information is also included within this letter. We anticipate continuing C
development of the subject building lot (Lot 7) will mostly be limited to minor grading activities
and building pad preparation. Based on our field observations, current conditions within the
CZ
subject lot should prove suitable for the continuation of lot grading activities. —1

Project Description • •
The Norpoint Heights residential development is located at the intersection between Norpoint
Way Northeast and Southwest 353`d Place in Federal Way, Washington and consists of a
single tax parcel (King County Parcel No. 252103-9048) covering approximately 3.05 acres.
The site has been partially developed with utility installation, stormwater management facilities
and the onsite roadway (Southwest 353`d Place). Lot 7 is located at the east central extent of
the site.
We understand that continuing development within Lot 7 will include cuts and fills on the order
of one to two feet to reach design grade. Based on our experience with similar projects and
our understanding of the proposed project, we anticipate that the new residential structure will
be two to three stories in height and constructed utilizing relatively lightly-loaded wood framing
supported on a conventional foundation. We estimate perimeter foundation loads will be on
the order of 1 to 2 kips per lineal foot and slab-on-grade loading of 150 pound per square foot
(psf).
If the above design assumptions are incorrect or change, ESNW should be contacted to review
the recommendations in this letter. ESNW should review final designs to confirm that our
geotechnical recommendations have been incorporated into the plans.
Surface Conditions
At the time of ESNW's site visit (December 2016), grading activities in the form of utility
installation, pond construction and grading and paving of Southwest 353rd Place had already
occurred. Based on our knowledge of the site and observations collected, grading within the
individual building site has been limited to minor cuts and fill placement (anticipated as
temporary placement of material cut from the grading of southwest 353rd street). At the time of
our site visit, final grading of Lot 7 had not been completed.
Subsurface Conditions
ESNW was onsite to view current site conditions as well as observe, log, and sample three
shallow subsurface explorations, excavated using a hand auger boring (HA) tool, along the
proposed building pads for the purpose of assessing soil and groundwater conditions. HA-1
will be used to characterize representative subsurface conditions for the subject Lot 7. The
hand auger boring was advanced to a maximum exploration depth of three-and-one-half feet
below existing grades. The following is a general description of the soil and groundwater
conditions encountered at the hand auger location. Please refer to the attached hand auger
boring logs for a more detailed description of the subsurface conditions.

•
Lennar NW ES-4908.02
January 17, 2017 Page 3
Topsoil was primarily encountered underlying shallow fill material at HA-1 and was observed to
be between approximately 18 inches thick. The topsoil was characterized by a dark brown
color, the presence of fine organic material, and small root intrusions. Fill material was
encountered at HA-1 and primarily identified as brown silty sand with gravel in a medium dense
to dense and moist condition. In general, the fill material was observed extending one-and-
one-half feet below existing grades. We anticipate that fill within the area can be attributed to
road grading activities with current grades in the area not accurately reflecting final design
grades.
Native soil conditions encountered were preliminarily identified as silty sand with trace to
significant gravels. The native silty sand was observed extending to the termini of the
subsurface exploration location and was generally encountered in a medium dense to dense
and moist condition.
Geologic Setting
The referenced geologic map indicates the subject site is underlain by glacial till deposits (Qvt),
locally referred to as Vashon till or hardpan. The referenced Web Soil Survey (WSS) resource
indicates soils of the Alderwood gravelly sandy loam series (Map Unit Symbol: AgC) across the
subject site. The Alderwood series formed in glacial till on ridges and hills. Soil conditions
likely to be encountered during construction activities are anticipated to be as outlined within
this section.
Groundwater
During our subsurface exploration completed on December 28, 2016, groundwater seepage
was not encountered at the hand auger boring locations. However, localized discrete zones of
groundwater seepage may be encountered within site excavations. It is noted groundwater
seepage rates and elevations fluctuate depending on many factors, including precipitation
duration and intensity, the time of year, and soil conditions. In general, groundwater flow rates
are higher during the wetter, winter months.
Site Preparation and Earthwork
Based upon the referenced Grading Exhibit, we anticipate cuts and fills on the order of one to
two feet will be necessary to bring the proposed Lot 7 building site to design grade. From a
geotechnical standpoint, the native soils encountered at the hand auger boring location can be
considered suitable for use as structural fill and foundation support. Soils encountered during
our subsurface exploration are considered sensitive to moisture and will degrade rapidly when
exposed to excessive moisture during construction disturbances. In this respect, a contingency
for soil amendment or import should be included in the earthwork budget.
Earth Solutions NW,LLC
Lennar NW ES-4908.02
January 17, 2017 Page 4
Foundations
Based on the result of our evaluation, new foundations for the Lot 7 residential structure may
be supported on conventional foundation systems bearing on competent native soil or
structural fill used to establish building lot elevations. Where loose or unsuitable soil conditions
are exposed at foundation subgrade elevations, compaction of the soils to the specifications of
structural fill, or overexcavation and replacement with structural fill will be necessary. Any
topsoil within the building pad should be removed and the area restored (as needed) using
suitable structural fill as recommended by the geotechnical engineer at the time of lot grading
and construction. Based on the subsurface soil conditions observed during our field
exploration, we anticipate competent native soil suitable for foundation support will be exposed
at a depth of approximately three to four feet below existing grade across the majority of the
subject lot. Loose material exposed at foundation subgrade elevations should be re-
compacted or overexcavated and replaced with suitable structural fill. ESNW should observe
subgrade conditions,
the exposed foundation
prior to the placement of concrete formwork, to
confirm that acceptable bearing conditions have been achieved and to provide supplementary
recommendations, if necessary.
Provided that the structure will be supported as described above, the following parameters can
be used for design of the new foundations:
• Allowable soil bearing capacity 1 2,500 psf
• Passive earth pressure 300 pcf (equivalent fluid)
6Coefficient of friction 0.35
A one-third increase in the allowable soil bearing capacity may be assumed for short-term wind
and seismic loading conditions. With structural loading as expected, total settlement in the
range of one inch and differential settlement of about one-half inch is anticipated. The majority
of the settlements should occur during construction as dead loads are applied.
Retaining Wails
Retaining walls, if utilized, should be designed to resist earth pressures and applicable
surcharge loads. The following parameters can be used for retaining wall design:
• Active earth pressure (yielding condition) 35 pcf(equivalent fluid)
• At-rest earth pressure (restrained condition) 55 pcf
m Traffic surcharge (passenger vehicles) 70 psf(rectangular distribution)
• Passive earth pressure 300 pcf(equivalent fluid)
• Coefficient of friction 0.35
• Seismic surcharge 6H*
* Where H equals the retained height(in feet)
Earth Solutions NW,LLC
• .
Lennar NW ES-4908.02
January 17, 2017 Page 5
Drainage should be provided behind retaining walls such that hydrostatic pressures do not
develop. If drainage is not provided, hydrostatic pressures should be included in the wall
design.
Retaining walls should be backfilled with free-draining material that extends along the height of
the wall, and a distance of at least 18 inches behind the wall. The upper one foot of the wall
backfill can consist of a less permeable soil, if desired. A perforated rigid drainage pipe should
be placed along the base of the wall, and should be connected to an approved discharge
location.
Drainage
During our subsurface exploration, groundwater was not encountered within the hand auger
boring location. As such, we do not anticipate significant groundwater intrusions during site
construction activities. Should groundwater be encountered, temporary measures to control
groundwater and surface water runoff during construction will likely involve passive elements
such as interceptor trenches and sumps, as necessary.
Surface grades must be designed to direct water away from buildings, temporary/permanent
slopes and walls. The grade adjacent to the structure should be sloped away from the
structure to a suitable area, as practical. In our opinion, footing drains should be installed at or
below the invert of structural footing elements.
Preliminary Infiltration Evaluation
As part of our addendum letter preparation, we preliminarily investigated the hydrologic
capacity of site soils based on our shallow subsurface exploration, the previously prepared
study, and anticipated site conditions. Silty sand with gravel (glacial till) was primarily
encountered during our shallow subsurface exploration. In general, glacial till deposits exhibit
poor infiltration characteristics and should not be considered suitable for full infiltration
implementations. However; utilization of limited infiltration facilities or Low Impact Development
(LID) implementations may prove feasible, with successful use heavily depending on in-situ
conditions. As such, if individual lot infiltration is to be pursued, ESNW should be retained in
order to further evaluate the hydrologic capacity of the site soils.
Seismic Considerations
The 2015 IBC recognizes ASCE for seismic site class definitions. If the project will be
permitted under the 2015 IBC, in accordance with Table 20.3.1 of ASCE, Minimum Design
Loads for Buildings and Other Structures, Site Class D, should be used for design. In our
opinion, provided the proposed structure is supported as recommended in this letter,
liquefaction susceptibility is considered very low with respect to settlement impacts. The
absence of a uniformly established groundwater table and the relative density of the native
soils were the primary basis for this characterization.

Additional Services
ESNW should also be retained to provide earthwork observation and testing, and further
consultation services during development and construction. The recommendations and
conclusions provided in this geotechnical addendum letter are professional opinions consistent
with the level of care and skill that is typical of other members in the profession currently
practicing under similar conditions in this area. A warranty is not expressed or implied.
Variations in soil and groundwater conditions observed at the hand auger boring locations may
exist, and may not become evident until construction. ESNW should reevaluate the conclusion
in this geotechnical addendum letter if variations are encountered.
We trust this geotechnical addendum letter meets your current needs. Should you have
questions regarding the content herein, or require additional information, please call.
