Garrett Dean with GEO Group Northwest, Inc. was on site at the above address on February 3, 2023 for the
following geotechnical inspections.
Observe and Monitor Excavations & Grading
We observed that earthwork continued at the site today. The demolition and removal of the lower retaining wall
that was encroaching into the right-of-way area south of 172nd St SW was completed. The right-of-way grading to
a 2H:1 V slope at this time, per the project plans. No water seepage was observed in the excavations at the site or
during grading. In our opinion, the excavation and site soil conditions appear to be in acceptable condition and
stable at this time.
Segmental Block Wall Construction
We observed the wall subgrade was compacted with several passes of a jumping jack. Several inches of 5/8-inch
with minus fraction crushed rock was placed on the soil subgrade as a base course for the wall. We observed the
base course compacted with several passes of a jumping jack. We used a 1/2-inch diameter T-handle probing rod
to verify the subgrade and base course was compacted to a suitable degree. In our opinion, the subgrade is
acceptable for wall support. Placement of the first course of the wall blocks began near the northwest property
corner.
Erosion Control -Temporary
We did not observe flow of sediment -laden water off of the site. A silt fence was installed downslope of the
disturbed soils at the site; in combination with the non -woven filter fabric silt catch installed into the adjacent storm
utility, it is our opinion that temporary erosion controls for the site remain acceptable at this time.
