geotechnical review of Reference 6. Based on our review, the Geotechnical Consultant has
responded to our prior comments and we have no additional comments. Observation and
testing by the Geotechnical Consultant during grading and construction should be required
to verify anticipated conditions or to revise the geotechnical recommendations as considered
necessary. A final geotechnical report of grading and construction should be required.
The opportunity to be of service is sincerely appreciated. If you have any questions
regarding this review, please contact this office at your convenience.
Sincerely,
