FOUNDATION EXCAVATION REVIEW /6( ��?%
LOT 3 — MAPLECREST
WASHINGTON COUNTY, OREGON
GeoPacific Engineer, Jim Imbrie, visited the above- mentioned site to review foundation excavations
and subgrade bearing conditions. We understand that the proposed residences are two -story single -
family homes with slab -on- grade garage floors and raised wood floors on the lower level living space.
The excavation exposed stiff, native!, clayey SILT on the back half of the home and medium stiff to stiff
silt fill at the front. The observed subgrade is adequate for spread foundation support to a maximum
allowable bearing pressure of 1,50,0 psf . Footings should remain outside of a 1 H:1 V plane from
vertical cuts. No deck footing, patio, or other appurtenant structure subgrades were observed
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 warranty is herein expressed or
implied. This report was prepared for Windwood Homes only and should not be relied upon by third
parties without consulting GeoPacific. If you have any questions, please call.
Sincerely,
