As you requested, a site/soils investigation was performed on these three adjacent lots on January
18, 2002. Design for the site is as follows:
All unsuitable fill, vegetation, and un buildable matenal have been removed, The natIve soil is a silty-
clay loam with a Unified SOils ClassificatIon of ML and a plasticity index of less than 15. The
expansiveness of the soil IS low (after Holtz 1959) A maximum 4" of crushed rock should be
Installed with tracked excavation equipment to protect the proposed building site in the event of
inclement weather. No extraordinary drainage or compaction is required for treatment of expanSive
soils at thIs site.
On January 29, 2002, a compaction inspection was preformed after fill placement on Lot 110, The
compacted surface of the 1 %" minus crushed rock is adequate for a foundation bearing capacity of
1500 psf, with the exception of the area south of rear garage foundation. This area had been
driven on by a loaded dump truck causing the sub grade to intermix with the crushed rock, This IS
crawl area where individual footrngs are to be installed to support the 32" on center floor beams.
The contractor was instructed to hand excavate to firm bearing and then place the concrete for the
individual pads in the excavated holes. There are 12 pier locations where thiS needs to be
preformed and when accomplished, the site WIll be adequate to support the proposed conventIonal
wood framed residence.
Thank you for this opportunity to be of service. The enclosed Building AnalysIS Report and
Statement of Conditions is a part of this report If you have any questions regarding this report,
