RE: 2709 Walters Port Lane (Ref : Dunkle' R silence)
Orono, Hennepin County, Minnesota
As requested, a site visit was made on F r L.Irr 26, 2007 at 1:19 P.M.
to evaluate reported questionable ocils n in excavaLion, for
construction of an attached garage at a 610 amily residen ial
structure.
At the time of the inspection, the resid 1w under going extensive
renovation and an existing garage had boo, f m ed from the ste.
Observations indicated that the new cons i will general 'y occupy
the footprint of the previous structure, t: it to the west side of
the residence. Footing trenches, at app i a tly 4 feet in depth,
had been completed in the east/northeast eluded 1 to 1 1/2 foot
steps to lower elevations in the NE and _ �II r rs-
Soils at the base of the footing trenche b`sted of a mois
slightly mottled, sandy lean clay, with Aiha saturation of surface
soils near the mid-point of the east foo 1 e. To assess the
strength of the soils, a 5/8th inch dia s oth probe was uswd to
penetrate the soils at random along the n lines. With full body
weight applied, the probes indicated pen aii of 4 to 5 in hes,
consistent with soils of acceptable consta t n.
The footing excavation within the SW sect »I �o the pad, which
contained reported questionable soils, h :6 -11
6 e temporarily backfilled
prior to our arrival . Observations were the south line was
re-excavated near the east and. At tho 9x ato mid-point of the
trench, loose fill materials were encount. d the trench as
subsequently sub-cut 2 feet to achieve c e soils, with he
excavation extended west to the sw corner' >r organics and ecayed
woody materials were observed.
The trench was sub-cut an additional 1 1/ 1 f t at the SW corner, to a
gray silty clay, removing the referenced it ble organic/w ody
materials. Probes conducted the length o l trench indicated
acceptable strength, with a moderate incr s 1 penetration to 101',
within the sub-cut zone at the SW corner. A 1 /8" fluted ha auger

probe placed to a depth of 3 feet at th ti c I iner indicated cohesive
soils at depth, with a rapid recovery i 1 strength beyone 70 to 12
inches. Based on soil observations of Milleted sections , we
would anticipate acceptable soils as the t ind north footing lines
are complo l in the northwest .
To evaluate the relative loadbearing cap itj f the subqrade soils, 2
dynamic cone penetrometer tests were con at the base o the
footing trenches. The dynamic cone pens o t r (DCP) , employs a
eight kilogram (17. 6 pound) hammer to dr e 0 millimeter diameter
conical point into the soil , with the pe t t n recorded i
millimeters per blow. From the DCP read g per blow, penetration
average was recorded and a N-value deriv TAS N-value, is an
empirical relationship we have establishequate the dynamic cone
data to the more familiar blows per foot ) tandard panet ation
