FOUNDATION EXCAVATION REVIEW
LOT 4 — f .k 'LECREST
WASHIR 'ON COUNTY, OREGON
GeoPacific Engineer, Jim Imbrie, vi the above - mentioned site to review foundation excavations
and subgrade bearing conditions. We understand that the proposed residence is a two -story single -
family home with raised woods. The excavation exposed stiff, native, clayey SILT on the back half of
the home and medium stiff to stiff silt fill at the front. Some of the fill was removed and replaced with
compacted gravel that tested above 90 percent maximum dry densty. The current subgrade is
adequate for spread foundation support to a maximum allowable bearing pressure of 1,500 psf .
Footings should remain outside of a; 1 H:1 V plane from vertical cuts. Some backfilling of vertical cuts
may need to be performed.
Our work scope pertains to a geotechnical engineer's foundation excavation review only and the
conditions existing and exposed at the time of our site visit. No warranty is herein expressed or
implied. This report was prepared for Windwood Homes only and should not be relied upon by third
parties without consulting GeoPacific. If you have any questions, please call.
Sincerely,
GeoPacific Engineering, Inc.
