Wade Lassey of Geo Group Northwest, Inc. visited the site to evaluate the site soil and excavation
that has taken place.
Excavation Monitoring
The site soils have been vertically cut about 8 .feet. The soils consist of bedded sand, gravelly
sand, and sandy gravel. The soil is dense to very dense about 3 feet below the existing ground
surface. There is no water seepage. The vertical cut is not sloughing and appears stable.
(Prepared document titled, "Open. Cut and Elimination of Shoring," dated August 8, 2007)
Erosion Control:
We recommended that additional silt fenciing be added on the west side of the rock construction
entrance and that geotextile filter fabric be installed in the existing stormwater catchbasins in the
street.

Wade Lassey of Geo Group Northwest, Inc. visited the site to monitor the site excavation, erosion
control, and soil beating.
Excavation Stability Monitoring
The temporary cut along the south property line has been made. The top is out at about l H: i V.
The rest of the cut is near vertical. The soils are dense and the cut appears to be stable. No signs
of sloughing or instability was noted.
Erosion Control
Additional silt fencing has been added west of the rock construction entrance and geotextile filter
fabric has been installed in the street catchbasins. The erosion control appears to be acceptable at
this time.
Soil Bearing Verification
The site soils in the footing areas are dense and will support the allowable 2,000 psf soil bearing
pressure, based on probing with a 1/2 -inch steel rod.
East Footing Lime
The upper east footing is located at the top of an 8 foot tall near vertical temporary out. Loads
should not be put on this footing until after the lower basement wall is constructed and is
backfilled. The wall backfill will be supporting the upper footing, so tl-te backfill should be
compacted to strutural fill specifications. It is recommended that the basement wall be backfilled
with croshed rook, or a similar material, that can easily achieve structural fill compaction
specifications. For safety purposes, persons should not compact between the wall and cut until
there is less than 4 feet of backfill remaining to the top of the cut.

Wade Lassey of Geo Group Northwest, Inc. visited the site to monitor the site excavation and
condition of the erosion control.
Excavation Monitoring
The temporary cut along the south property line continues to appear stable. No sloughing or other
signs of instability was observed.
Erosion Control
The site erosion control appears to be acceptable at this time.
We understand that the City's inspector requested that the temporary cut slope be coveted for
erosion control. It is our opinion that the cut slope should be left uncovered at this time in order
for the stability of the slope to be monitored. Although the rains to date have been relative light,
there has been no sign of erosion on the temporary cut slope. Slope movement or instability
would be masked if the slope was covered.
