Dear Mr. Smeby:
Subject: Design Plans Review

Earth Science
At your request, we have completed a geotechnical review of the design plans for the
subject project. It is our opinion that the design plans are substantially in compliance
with the recommendations in our 9/26/2005 geotechnical report and subsequent
correspondences.
Cut banks in surficial loose sand soil in excavation for detention pipe installation may
cave suddenly. Therefore, cut banks should be stabilized with shoring blocks during
construction.
Yours very truly,
