GeoPacific Engiiieur, Jim imbrie, visited the site today to review the toundation excavation subgrade on the
above - referenced lot. The observed subgrade is basalt 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 3,000 psf.
Our work scope pertains to a geotechnical engineer's foundation excavation rovicw 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 expresJ Or implied. If you have any questions, please call.
