FOUNDATION SUBGRADE REVIEW
LOT 24 RIVER TERRACE CROSSING
15557 SW PEACE AVENUE
WASHINGTON COUNTY, OREGON
Reference: NV5, Revised Summary Letter Geotechnical Construction Observation Services, Phases
1 and 2, River Terrace Crossing, SW Woodhue Street SVP150th Avenue, Tigard,
Oregon, dated September 30, 2022.
GeoPacific Engineering Inc. visited the site yesterday to review the single-family home foundation
subgrade at the above address. We understand that the proposed building is a two-story home. In
our opinion, the observed subgrade is adequate for support to an allowable bearing pressure of
1,500 psf. The mass grading of the site was observed and tested by others.
At the time of our site visit, the excavation was nearly complete, and soils exposed in foundation
excavation consisted of predominantly rocky fill with gravel with to stiff fill soils that could be probed
about 1 to 2 inches with moderate pressure using a steel "T" bar probe. Up to 2 feet of soft fill was
removed from the front of the home. The lot is gently sloped; footing to slope and footing to wall
setbacks were not an issue. The expected maximum anticipated total and differential footing
movements (generally from soil expansion and/or settlement) are 1 inch and % inch, respectively,
over a span of 20 feet.
Due to relatively impervious silty and clayey soils encountered throughout the site, all foundations
should incorporate appropriate drainage measures in accordance with the International Residential
Code. Adequate crawlspace drainage is not something that geotechnical consultants can verify; the
purpose-of our visit is for observations of foundation bearing conditions only.
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. Within the limitations of scope, schedule
and budget, GeoPacific attempted to execute these services in accordance with generally accepted
professional principles and practices in the fields of geotechnical engineering and engineering
geology at the time the report was prepared. No warranty, express or implied, is made. If you have
any questions, please call.
