RE: Subgrade EveluatlDn
Levi Landing - Zook Residence
Lot 107 - Arran lane
Springfield, Oregon
(J (p ilo Prct y- () v'\ L (\)
On October 29, 2001, a representative from Ford-Nesl-Fassbender, Inc. observed and hand-
probed the bUilding pad subgrade an the above referenced r~slClientlal building lot to assels the
subgrade bearing capacity and shrink/lwell potential of the lair,
Lot 101 - Permit No.
The building pad had been over-excavated to remove surface vElgetetion and to expose a
clayey silt/silty elay sLlbgrade sail, The pad appears to have been constructed atop less than 1-
to 2..feet of fill. The subgrade is covered with approximately 2 inches of compacted crushed
aggregate. The soli 8ubgrade had a moderate shrink/swell potentlal and Is suitable for an
allowable bearfng t;apacity up to 1.500 psf The aggregate COVE~r will act to stabilize the soil
mOisture content, thereby mitigating the potential for shrfnklsweli of the soli.
The b~i1ding pad IS suitable for conventional residential construction With perimeter spread
footings,
We recommend the landscape soil slape to direct surface water away from all fo~ndations, and
water should not pond adjacent to footings. Drainage from adjacent praperties should be
directed away from the foundatIons. We also recommend that perimeter footIngs be remforced
with at least two No 4 steel reinforCing bars.
