RE : REVISION FOR BA5IC PLAN 94B00299 ,�ut Z 3 1997
QUADRANT CORPORATION HOU5E PLAN 2230 MODEL A B
To Building Officials;
Enclosed are design revisions for the Basic Plan submitted previously. The design revisions involve
construction materials only, with no building alternation as:
1. Employ 1/2" plywood or OSB roof sheathing in lieu of lx spaced sheathing per UBC Table 23-I-J-1
and eliminate gypsum wallboard ceiling diaphragm, see framing details on sheet S 1 enclosed.
2. Use drywall screw as a alternative fastener at gypsum wallboard shear walls per ICBO Evaluation
Report 1874, see shear wa11 schedule on sheet S 1.
3. At all spread footings, change reinforced concrete to plain concrete per UBC 1923.10.3 exception.
11ie revisions included the alternatives for each model a�ld are engineered based on the following code
requirements and design criteria as:
1. 1994 Uniform Building Codes, Design Standards and ICBO Evaluation Reports;
2.Wa11 Bracing Test Report 156 and Research Report 151 by American Plywood Association;
3. Basic Wind Speed assigned at 80 MPH, Exposure B;
4. Seismic Zone Factor of 3 and Site Soil Type S2;
5. Roof Snow Loads assigned at 25 PSF;
6. Allowable Foundation Pressure assumed at 2000 PSF with field verification.
These revisions are submitted for the use of King County Building Department's review and approval of
Basic Plans only, and not for review and approval of building permit on any specific site. Century
Engineers Corporation will submit a certification letter addressing the conformance of each specific
plan's design criteria to the design requirements of a specific site or multiple sites,when building permit
applications are submitted or processed.
Century Engineers Corporation and its design professionals are not liable for any use without a
certification letter from us, nor for any misinterpretation of the engineering requirements that are
determined by site conditions of a specific site.We trust that this submittal rovides the information
required for revisions. Please call if you have any questions. ,� T. C�r�
Sincerely,

Reference: City of Federal Wey
Letter dated September 13, 199fi
Dear Mr. N�whail:
At your request, we are pleased to present this geatechnical engineering study for
Bellacarino Woods, �.ots 13 through 22, Federai Way, Washfngton. The purpose of
our work was to observe the general site conditions, review our previous work at the
site, review the recent grading activity and pravide geotschnical recommendations for
completing the grading and residence construction. Additionafly, this study addresses
the issues presented in the referenced letter by the City of Federa! Way.
PrQiect Descrietian
Lots 13 through 22 are situated within the Bellacarino Wood Residential Ptat, The
earthwork construction for the plat was performed in ihe spring and summer of 1995.
However, the grading at the s�bject lots was not completed due to weather.
At this time, it is ptanned to complete che grading of Lots 13 through 22. Grading
operaiions will consist of placing jhree Lo fifteen feet af additional fill in east por�ion
of these fots. The grading work was begun the week of September 9, 1996. This
work was Stopped by the City on September 12 with the requirement that this study
be completed prior to completing the grading. From the grading contractor,� we
undersi�nd it Should be feasibfe to finish the grading work in anoth8r one to two d�Ys.

The Eots will aventuafly be developed with singte-family residences. The residences
will be two to three stories in height and will be of relatively lightly loaded wood-frgme
construction with slab-on-grade floors.
Site Description
Lots 13 through 22 are situated on the easr side of 8"' Avenue Souttlwest, about 300
feet north of the intersection of 8`" Avenue and Southwest 356`h Cour�.
The lots have been graded to form two benches. The upper bench is at the elevation
of 8th Avenue �nd is on the order of thirty i30} feet w;de. Along the east edge of the
upper bench is a ten foot high, 2H:1 V slope which slopes down to the east. At the
toe of tl�e slope is the lower bench. The lowet bench ;s on the order of forty i40) feet
wide. The (ower bench is only partially compfete, with the lower bench of Lots 13
to 17 about five feet below the lower bench of Lots 18 to 22. After the gradin�g is
completed, the lower bench eievation will be approximately equal across alI nine lots.
Subsurfsce Conditions
The subsurface conditions were evaluated by reviewing our daily field reports f�om the
1995 grading operations, reviewing our field reports from the September 1996
grading �Ctivity and malcing a site visit to observe the current site conditions.
Lots 13 through 22 were initially �filled during the second and third week of May
1995. During jhis period, two to five feet of structural fill was pleced in the west half
of these lots. The origin�lly sloping ground surface wss bertched prior to fifl
placement to ensure a level area to support the fill. The fill consisted of silty sand
with gravel from �n on-site borrow area. Our field derSsity tests indicate this fill was
compacted to at ieast 95 percent maximum dry density in accordance with �the
Standard Proctor (ASTM D-698).
The Second week of September 1996, filling of the east half of th�se iots
comm�nced. The fill placed durin.g this period cansisted of''material generated from
fine grading the other lots in°Beliacarino Woods, materia(excavated from the detenxion
ponds and importsd soil,
All four fiill materiafs consist of sllty sand with gravel (Unified Soil Classitication SM?,
Our field density tests on the fill indicate it has been adequately compacted to at IQast
95 percent of maximum dry density in accordance with the Standard Proctor.

Di$cussion and Rp���+�;;a;�ations
Bssed on the resu(ts of our review, it is our opinion the site can be developed
generally as ptanned, In our apinion, suppprt for the residences can be provided using
conventional spread and continuous footing foundation systems bearing on the
structurai fill used to raise site grades, Slab-on-grade floors can be similarly
suppor��d. A soil-bearing v�lue af twenty-five hundred (2,5pp) psf may be used for
footing design.
This report has been prepared for specific appfication to this project only and in a
manner consistent with that leve! of care and skil! ordinarily exercised by o�ther
members of the profession currently practicing under similar conditions in this area for
the exclusive use of Newhail Jones, Inc. and their representatives. No warranty,
expressed or impfied, is made. This report, in its entirety, should be included in the
project contract documents for the information of the contracYor.
Site Prenaration and Gener�l Earthwark
We understand future earthwork construction will consist of completing the fill
placement in the west half of the south four to five lots. !n rhis area, it appears
another four to five feet structural fill will need to be piaced.
Structural fiil is defined as any compacted fill pl�ced under buiidings, roadways, slahs,
p�vements, or any other load-bearing areas. Structurat fill under ftoor stabs and
footings should be placed in horizonral lifts not exceeding twelve (12) inches in Idose
thickness and compacted to a minimum o# 90 percent of its iaborazorymaximum dry
density determined in accordance with ASTM Test Designation D-155�-75 (Modified
Proctor), The filt materials should be placed at or near their optimum moisture
content.
Prior to fill placement, the ground surface shou)d be observed by a representative of
ECI. Soil in any loosa or soft areas shouid be compacted or overexcavated .and
replaced with structural fill,
During dry weathet, most soils which are compsctible and non-organic can be used
as structura) till. If structural fili is to be place during wet we�ther, it should consist
af a granular material with a maximum size of six inches and no more than five
percent fines passing the No. 200 sieve.
The soi) previously used to fill the lots and the material planned to camplete the fiJiing
operation are moisture sensitive, As such grading af these soils should be planned for
periods of relatively dry weather.

Slope Inclinetiona •
All permanent cut and fill slopes should be inclined no steeper than 2H:1 V, The
existing 2H:1 V slope surfaces are loose. Recent rain has caused erosion and surficial
slough'sng of these sfopes. Tha slope surface should be compacted using either a
hoe-pac type of compactor on the slope surface or track-walking the slope wi�h a
sm�ll dozer.
The siopes shoulcf then be hydraseeded wizh a seed-mixture intended for use on
slopes or covered with straw-mu(ch,
Water should not be aiiowed to flow uncontrolled over the tap of the fill slopes.
Fitl Siope Placement
� In our opinion, the piacement of fill on slopes is generally acceptable; howev�r, where
D the slope exceeds 25 percent, the fill should be keyed and benched into the slope.
This process consists of excavating a keyway at the toe of the pisnned filf. The
keyway should ha�e a width of about six to eight feet and depth of two feet into
medium dense to dense native soil, The slope above the keyway should then be cut
into a series of horizontal to slightly inward sloping benches. Typically, the ben�hes
are excavatad with a small bulldozer as the fill is brought up. The width of the
benches wil! vary with the gradient of the slope, usually the gentler the slope, the
wider the benches.
FovncJ�tions
Support for the resider►ces can be provided using a conventional spread ,and
continuous footing foundation system bearing on�the structural fi11. �xterior foundation
efements should be placed at a minimum depth of eighteen (18) inches below final
exterior grade. Interior spread foundations can be placed at a minimum depth of
twelve t12) �nches below the top of slab, except +n unheated areas, where interior
foundation elements should be founded at a minimum depth of eightEen (18} inches.
With foundation suppor� obtained as described, for design, an allowable bea�ing
capacity of two thousand five hundred (2,50�) psf for structur�l fill can be used.
Continuous snd individual spread footings shoufd have minimum widths of eighteen
i18? and twenty-four t24) inches, respectively. Loading of this magnitude would be
pro�ided with a theoretical faczor-of-safety in excess of three against actual shear
failure. For Short-term dynamic loading conditions, a one-third increase in the above
allowable bearing capacities can be used.

Footing drains should be installed arour,d the building perimeter, at or just bElow the
invert of the footing, with a gradient sufficient to initiate fiow. Under no
circumstances should roof downspout drain lines be connected to the fooring drain
system. All roof downspouts must be separat�ly tightlined to discharge. CleBnouts
should be instalfed at strategic locatians to allow for periodic maintenance of the
footing drain and downspoUt tightline systems. Footing and roof downspouts should
not discharge onto the fill siopes.
Erosion Control
As previously discussed, fill slope surface is (aose and is erodin�.-These sfopes sh4uld
be graded to 2H:1 V gradient and the surface compected in place either using a tioe-
pac or by track-walking the s�ope with a small dozer. The slopes should theri be
hydroseeded using a seed mixture intended for use on siopes or covered with straw
muich.
