. — Phase 1, Tigard, Oregon, Revised January 21, 2004 (should state 2005),
GeoPacific Enginapr, Jim Imbrie, visited the site to review the foundation excavation subgrades. The
observed engineered fill is clay with rock. Based on our observations, it is our opinion that the current
foundation subgrade is adequate for spread foundation support to a maximum allowable bearing pressure of
1,500 psf. reirifcrcement has Deere recommended in the above Reference 2. The existing rockery
walls at the rear and side yard of the lots are adequately setback from the foundation such that they are
surcharged by the proposed construction,
Our work scope pertains to a geotechnical engineer's foundation excavation review only and the conditions
existing and wxpnsed at the time of our site visit. No deck footing, polio, or other appurtenant structure
subgrades were observed. Our work was performed to the current local standards of practice.' No other
warranty Is herein expressed or implied, if you have any questions, please call.
