Seepage's may be encountered within excavations. 'These seepage may flow steadily for a limited period of time and than abate due to the discontinuous nature of the sand seams from which the seepage occur or they may simply continue for a long time during extended periods of wet weather. The amount of seepage, its duration and the number of separate seepages encountered within an excavation may increase during extended periods of wet weather. Soil instability and side wall F'oughing may occur within a seepage zone. Cuts on this site will stand for short periods of time if not too steep. Cuts left exposed for longer durations of tittle should be protected from weathering elements through the placement and use of visqueen. Some sloughing niay occur along cut faces where seepage occurs. We recommend that GES, Inc. observe all cuts when first exposed and on a periodic basis there after. This inspection will confirm the consistency of materials with those encountered during the initial site investigation as well as verify the apparent safety of the cut. All cuts should be covered with visqueen and protected from rain, desiccation by the sun and erosion immediately alter this inspection has occurred. All cuts should be carefully watched and observed. If cracking or movement is observed, GES, Inc. should be contacted immediately to view the area and develop recommendations to remediate the problem. 4.5 Utility Placement Utility excavations should comply with applicable recommendations contained in section 4.4, Cuts and Excavations, of this report. We recommend that all utilities be placed at as high an elevation as is physically possible on this site. Fall through utility pipes should be maximized so that the increased head Will offset any possible effects caused by localized settlements in pipes placed through uncontrolled fill materials. Utility pipes should be made of as still' a pipe as possible. Excavations for utility placement should be performed in compliance with WSUUT Standard Specification section 2-09, Structure lircavarion. The depth of excavation, removal of unsuitable base materials and disposal of those materials shouhi be performed in accordance with applicable sections of this report. Utilities placed over I I GES, Inc.
