developmeht for the subject property Based on our observations and testing the site is
considered suitable for its intended residential use Geotechnical observations and testing
completed by this office during site grading, is summarized in the referenced report As
of this date, the site has not changed significantly since the completion of grading and the
issuance of the referenced report, thus, the findings, conclusions, and recommendations
presented in our referenced report, are generally considered valid and applicable with
respect to the,construction and development of the subject building pads Based on the
duration of time following pad completion pre-wetting is recommended, as indicated in
the referenced report Some surficial processing may also be necessary, owing to the
pasâebf'firne, erosion, etc. '
