FOUNDATION EXCAVATION REVIEW
LOT 11— WILSON RIDGE PHASE 1
WASHINGTON COUNTY, OREGON
Reference: GeoPacific Engineering, Inc. Soil Engineer's Summary At Conclusion of Earthwork,
Wilson Ridge Subdivision, June 4, 2006.
GeoPacific Engineering Inc. visited the site to review the house foundation excavation subgrade for
bearing conditions only. We understand that the proposed residence is a two -story single-family
home with a concrete slab -on -grade garage floors. The excavation exposed stiff native silt. The
observed subgrade is currently adequate for spread foundation support to a maximum allowable
bearing pressure of more than 1,500 psf. The native subgrade is likely to become softened by wet
weather; softened soil should be mucked out from beneath footings just prior to pour.
Our work scope pertains to a geotechnical engineers foundation excavation review only and the
conditions existing and exposed at the time of our site visit. No deck footing, patio, or other
appurtenant structure subgrades were observed. No warranty is herein expressed or implied. This
report was prepared for Venture Properties only and should not be relied upon by third parties
without consulting GeoPacific. If you have any questions, please call.
Sincerely,
GeoPacific Engineering, Inc.
