- Pnese 1, Tigard, Oscan. Revised Jen uary 21, 2004 (should stars 20051.
COeoPaclfic Engineer, Jim Imbrie, visited the site on more than one occasion to review the foundation
excavation subgrades on the above - referenced iota. The observed soils are compact engineered fill
consisting of clayey silt, with rooks; some of the fW was iv"r'oved on I.ot 20 along the cost aide adjacent the
rook watt. This fill was replaced with reject rock that was compacted, tested, end achieved project
specifications. Some mucking may be required If the sub*rade is left exposed to wet weather for a long
duration, however the current subgrade is fairly dry. The foundations are appropriately setback from the side
and rear yard rockery retaining walls,
Based on our observations, it is our opinion that the current foundation eubgrede Is adequate for spread
foundation support to a maximum allowable bearing pressure of 1.500 pee.
Our work scope pertains to a gsotechnicel engineer's foundation excavation review only and the conditions
existing end exposed at the time of our site visit. No deck looting, patio, or other appurtenant structure
aubpredes were observed. Our work was performed to the current local standards of practice. No other
warranty cl herein expressed or implied. If you have any questions, please call.
