Dear Mr. Wavrn:
At the request of Mr. Jim Moore, we provide this written geotechnical review of the foundation plans for
the proposed family reflecting pool. This written review is required in order to satisfy the requirements of
the County or Orange Plan Check Department, in preparing this letter, we have reviewed the previous
letter for the reflecting pool (Reference No. 14) and the foundation plans for the reflecting pool prepared
by KNA Structural Engineers and dated November I:, 2011.
Based on our review, the reflecting pool plans have been prepared in general conformance with the
recommendations and design soil parameters of our previous letter (Reference No. 14) and are considered
acceptable from a geotechnical point of view
We trust that this letter serves your needs at this time. Should you have any questions, please feel free to
call.
Respectfully submitted,
PETRA GEOTEC ICAL, INC.
