FOUNDATION EXCAVATION REVIEW 1 ' S 0'P.- C'
LOT 13—ASH CREEK ESTATES I "(\40
WASHINGTON COUNTY, OREGO 1
Reference: GeoPacific Engineering', Inc., Final Soil Engineers report, Ash Creek Estates, May 17,
2007
On August 28`^ and 29'" 2013, GeoPacific Engineer, Jim Imbrie, visited the above-mentioned site to
review foundation excavation and subgrade bearing conditions. We understand that the proposed
residence is a two-story single-family home with framed garage floor and a crawispace. The
excavations mostly exposed medium stiff to stiff, native, clayey silt and compacted fill in the garage
area.
The observed subgrade is adequate for spread foundation support to a maximum allowable bearing
pressure of 1,500 psi. Footings should remain outside of a 1 H:1 V plane from vertical cuts. GeoPacific
should review the final backfilled configuration and perform density tests as necessary on the backfill.
No deck footing, patio, or other appurtenant structure subgrades were observed
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,
