- Phase 1, Tigard, Oregon, Revised January 21, 2004 (should state 2005).
GeoPacific Engineer, Jim Imbrie, visited the site March 4, 2005 to review the foundation excavation subgrade.
The observed subgrade consisted of compact fill with some rock. The house is sufficiently setback from a
small rockery retaining wall such that it Is not surchargin the wall. Based on our observations, it is our opinion
that the currentfoundation 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 porteins to a geotechnical engineer's 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. 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 cell.
Sincerely.
