Dear Mr. Hatch:
In accordance with the request of Mr. Dan Loss with Pasco Laret Suiter & Associates, we reviewed the
referenced retaining wall plans and calculation for the subject development.
Based on our review of the referenced plans and the information contained within the referenced
geotechnical report, we opine the soldier beam and soil nail retaining wall plans and details have been
prepared in substantial conformance with the recommendations presented in the referenced geotechnical
documents.
We limited our review to geotechnical aspects of project development and the review did not include
other details on the referenced plans. Geocon Incorporated has no opinion regarding other details found
on the referenced plans, structural or otherwise, that do not directly pertain to geotechnical aspects of site
development.
