RE: QEOTECHNICAL ENGINEER'S FOUNDATION EXCAVATION REVIEW
THORNWOOD LOT 49
CITY OF h OARD, OREGON
Reference: GeoPacific Engineering Inc., Soli Engineer's Summary at Conclusion of Earthwork,
T omwaod City of Tigard, Oregon, dated March 16, 2003.
GeoPacilic Engineer, Jim Irrlbrle, has visited the above- referenced lot on August 26"'. The purpose of
our visit was primarily to review the foundation excavation subgrade, end footing proximity b existing
slope faces and terrace cuts. The nearest adjaoent footing (southwest corner) for the subject
raeidenoe is approximatsly 5 feet from the natural slope face which Is only approximately 20 percent
grade for at least 20 feet. The southeast corner Is at the base or the fill elope.
The footing subgrade generally consisted of engineered fill on the front embankment and natural ells
at the lowest (rear) portion of the home. Both soil types probed stiff to very stiff after a minor removal
at the SW corner of le® than 8 inches, The current subgrmde Is considered adequate for spread
foundation support. Based on our observations, the foundation subgrade and excavation setbacks
should be acceptable for support d the proposed single-family home.
Our work scope for this phase of geoteohnlcal review pertains to foundation bearing conditions only
and is limited to the conditions etdadng and exposed at the time of our site visits. If you have any
further questions, please call,
Sincerely, •
GeoPadflo Engineering, Inc.
