RE: 751 So 48th - SIte/SOlis/Compaction InvestIgatIOn - Job #492-05
As you requested, a sIte soils investigation was performed at the above address
Allul1suitable fills, orgaIllcs and other unsuitable material has been removed to sUitable grade. The
native soil on thIs site IS silty clay loam with a Unified Classd'ication of ML and a plastIcIty II1dex of less
than 20. TIllS soil IS not consIdered expansIve (after Holtz 1959). These soils are sUItable for the
placement offootmgs for the proposed wood framed structure No extraordinary dramage is requIred for
this site
Crushed rock was placed m excess of 6" to raise and level the budding pad to the desired elevatIOn for
the proposed foundation A compactIon inspection on the gravel fill was performed. The compacted
surface of the 1 W' minus crushed rock is adequate for the proposed foundatIOn and has a mimmum
bearing capacity of 1500 psf The compactIon of the gravel surface is greater than 95% of a standard
proctor per ASTM 0698
This report is limIted to the sIte SOils investIgatIon related to s01ls and fill m regard to soil conditIOns at
the excavated structure sIte at the above address only

RE' 751 S. 481h - Drainage - Job #492-05
As you requested, an inspection reVIew of the above site was performed. The site is in a gently
sloped area and the foot1l1gs will be placed on compacted crushed rock at approXimately curb
height. Plac1l1g under floor drams at 6" into tlle compacted crushed rock wIll not provide the
required diversion of surface waters away from the down slope sites in this area, and will not
allow for fall to the street. It IS recommended to place 3" ~iameter perforated perimeter footing
drain at the up slope side of the structure only, changing the drain line to solid past the edge of
the foundation, and direct the drain to a street cllrb cut. The perforated drain line is to be place at
the base of the footing WIth the solid portion of the dramhne to be sloped at approximately 1% to
the street. Clean round rock is to be placed over the perfo~ated drainline portion. Clean, well
drained backfill, with no expansive soils, IS to be llsed for the back fill around the entire
structure, except at the driveway. I
ThIS method of diverting the water around the foundation w111 provide the required surface water
diversion from the foundatIOn, in that water WIll always take the path of least resistance The
water will seep through the clean loam backfi1l1l1to the trench of clean round rock that has been
placed over the perforated drain pipe, 1I1to the pipe and away from the structure's foundatIOn.
Thank you for this oppOliunity to be of service. If you have any questions regardmg this report
contact me at 868-0667
Smcerely,
Pamela S. Hillstrom, P E.
