RE: Subgrade Evaluation
Levi Landing - Thomas Residence
L.ot 104 - Arron LIne
Springfield, Oregon
lo \u'6' Ao"oV\ LN
On October 29, 2001, III representative from FoRf"Ness-Fassbender, Inc. observed and hand~
probed the buildIng pad subgrade on the above referenced residential bUilding lot to assess the
slJbgrade bearing capacity and shrink/swell potential of the sOli
Lot 104 - 'Permit No.
The building pad had been over..excavatect to remove surface vegetation and to expose a
clayey silt/silty clay 5ubgrade soli. The pad appears tQ have been constructad atop le,;s than 1-
to 2.feet of fin. The subgrade is covered with approXImately 2 Inches of eompacted crushed
aggregate, The soil subgrade had all moderate shrink/swell potential and is aUltable for an
allowable bearing capaCity up to 1,500 pst. The aggregate covlerWlIl act to stabilize the sod
mOisture content, thereby mitigating the potential for shrink/swell of the soli.
Tt1e bLllldlng pSQ IS sUitable for conventional residential c::cnstrudion with perimeter spread
footings.
We recommend the landscape soil srope to direct surface water away fram an foundations, and
water should not pOnd adjacent to footings, Drainage from adjac:ent properties Should be
directed awa.y from the foundations. We also recommend that pan meter footings be reinforced
with at least two No, 4 steel reinforcing bars
