— Phase 1, Tigard, Oregon, Revised January 21, 2004 (should state 2004
GeoPacific Engineer, Jim Imbrie, visited the site yesterday to review the foundation excavation subgrade. The
observed subgrade consisted of compact fill with some rock. The house is sufficiently setback from a small
roc,*cry retaining well such that it is not surcharging the wall, Erased 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. Minimum reinforcement has been recommended in the above Reference 2. No deck,
patio or other subgrades exterior of the home were reviewed.
Our work scope pertains to a geotechnicat engineer's foundation excavation review only and the conditions
existing and exposed at the time of our site visit, 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.
