Dear Mr. Rick:
In accordance with your request, Hetherington Engineering, Inc. has provided third-party
geotechnical review of Reference 9. Based on our review, the Geotechnical Consultant
has responded to our prior comments and we have no additional comments. Obsçrvation
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.
