As you requested I performed site soils inspections on May 6 & 9, 2002 at the above noted location.
During that inspection I made the following observations
The site soils consist of an 8 - 12 inch layer of organic topsoil with a sub soil of clay that is dispersed
with large boulders. The clay is classified as a CH in accordance with the USCS system. The PI of the soil
is approximated at a value greater then 35 making it have a very high degree of expansion (After Holtz
1959). Recommendations for the site are as follows.
May 6, 2002
The site needs to have all of the organic layer removed and place a minimum of 12 inches of crushed rock
as a base for the foundation. The rock needs to be compacted to 95% of a standard proctor. The native
grade needs to be cut so that it slopes towards the natural fall at the NW comer of the lot so that no water
can sit on the sub surface.
May 9, 2001
The site has been prepared in accordance with my recommendations as stated above. The rock is placed to
a minimum of95% compaction based on a standard proctor. The as constructed is adequate to support a
standard residential foundation
Thank you for this opportunity to be of service. If you have any questions please don't hesitate to call me
