This report presents the results of our field exploration, selective laboratory testing, a��d engineering analyses. The purpose and scope o( our swdy were ouUined in our Apiii 23, 2002 proposal. Based on the results of our field exploration, the descending slope on the north side of tiie residence contains up to eight feet of very loose to loose fili and native soil. An existing retaininc� wall constructed along the top of the descendinc� s'ope and several deck supports on the northeast side of the residence have exhibited settlement and lateral movements. The existing residence was constructed in 1989, and it is our understanding the retaining wall was constructed around U�e time of the residence. The wall offset and setdement were present in 2000 when purchased by the currer; property owners. Tlie descending slope appears to be marginally stable and tlie existiny very loose to loose fill and native soils will likely continue to settle and "creep" downslope. Due to the lateral movements exhibited by the existing timber retaining wall, it is our opinion the wall has failed and siiould be replaced. Foundation support for tlie existinc� deck posts sliould also be reestablished. Several alternatives for repairing and stabilizinc� the existing fill area are presented in this report. �H05 13Gth Place N.E . Suite 201.
