- Phase 1, Tigard, Oregon, Revised January 21, 2004 (should state 2005).
GeoPacific Engineer, Jim Imbrie, visited the site to review the foundation excavation subgrade. The observed
native soils are stiff clayey silt. Based on our observations, It is our opinion that the current foundation subgrade
is adequate for spread foundation support to a maximum allowable bearing proscurc of 1,500 psf. Minimum
reinforcement has been recommended in the above Reference 2. The existing rockery walls at the rear of the
lots are adequately setback from the foundation such that they are not adversely surcharged by the proposed
construction.
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 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 call,
Sincerely,
GeoPacific Engineering, Inc.
