RE 871 S 72nd St. - Site SOlls/Compactlon Investigation. W.O.#14926-ARC - B.P.#2002-01-209
As you requested, a site soils investigation was performed at the above noted address on
November 2, 2002. Design for the site IS as follows
All fill, vegetation, and unbuildable matenal has been removed to natiVe grade. At the upper bench
the surface SOil IS a Silty clay loam with a UnifIed Soils Classification of Ml-CL and a plastICity index
less than 15 A stnp of clay SOil with a Unified Salls Classification of CL and a plasticity index greater
than 20 IS approximately 24" below grade. The SOil IS hIghly expansIve. A minimum 12" of
undisturbed sOil IS to be left over the clay strrp to moderate the effect of the expansive soils at the
proposed bUIlding site. At the middle and lower bench the native soil IS a gravelly clay loam with a
Unified SOils ClasSIfIcation of GC and a plasticity index less than 15. Crushed rock is to be placed in
6" lifts to bring the site up to deSired finished grade. The crushed rock should be placed and then
compacted Wlt~ either a VIbratory plate or roller. Drainage shall be installed at the perimeter footings
to help maintaIn optimum soil moisture at the sIte. With the undisturbed soil and the placement of
the crushed rock, combined with the excavation that is of adequate depth and width, the site as
prepared IS adequate to aSSure a stable mOisture content for the proposed foundation.
On November 4, 2002 a site and compaction Inspection was performed after fill placement at the
t middle and lower benches. The excavation meets the reqUIrements as speCIfied in thiS letter The
compacted surface of the crushed rock IS adequate to support a conventIonal wood framed
residence With a standard foundation per the 2000 State of Oregon One and Two Family Dwelling
SpecIalty Code as adopted per the local junsdiction. The compaction of the gravel surface is greater
than 95% of a standard proctor, per ASTM 0698-91_

As you requested. a Site soils investigation was performed at the above noted address on
November 2, 2002. Design for the sIte is as follows'
All fill, vegetation, and unbUlldable matenal has been removed to native grade At the upper bench
the surface Sallis a silty clay loam with a Unified Soils Classification of ML-CL and a plasticity index
less than 15 A strip of clay SOil With a Unified SOils Classification of CL and a plasticity Index greater
than 20 IS approXimately 24" below grade. The soil IS highly expansive A minimum 12" of
undisturbed soil IS to be left over the clay stnp to moderate the effect of the expansive soils at the
proposed building site. At the mIddle and lower bench the native soil is a gravelly clay loam With a
UnIfied Salls ClassIfication of GC and a plasticity index less than 15. Crushed rock is to be placed in
6" lifts to bring the site up to deSired finished grade. The crushed rock should be placed and then
compacted With either a vibratory plate or roller Drainage shall be installed at the penmeterfoOtlngs
to help maintain optimum soil moisture at the site. With the undisturbed soil and the placement of
the crushed rock, combined with the excavation that IS of adequate depth and Width, the site as
