Proposed Reteil Development J-1443 1 l2'^Street and Hwy.99 Febcuary 26,2004 ( Evetett,Washingron Page 22 � described in the Subsurface Conditior�a section of this report. The sands appeaz to be lughly susceptible to erosion and would likely require protection. Grouadwater seepage may aleo have an impact on both temporary and petmanent slopes along the stream, as well as the design and construcrion of walls or rockeries that may be necessary W define the stream course. Dewatering mcasures may be necessary during the construction of the channel. The magnitude of dewatering will likely be dependent on the time of year that construction takes place and can only be determined at the time of construction. �LOSURE The conclusions and recottunendations presented in ihis report are based, in parl, on the explorations accomplished for tlus study. The number, location, and dep� of the explorations were completed witk�in the constraints of budget and site accesa so as to yield the infarmation w formulate the recommendatioiu. Project plans were in the preliminary stag at the time of t6is repo:t preparafion. We therefore recoromend that ZZA be provided the opportunity to review the project plans and specifications when they become a��ailable in order to confinn that the recommendations and design conside:ations presented in this report have been properly interpreted and implcmented into the project design package. The integrity of eazthwork, structu�al fill, and foundation and pavement perfonna►ice depend �ready on proper site preparation and construction pmcedures. We recommend that a qualified geotechnical engineering firm be retained to provide geotechnical engineering services ( during the earthwork-rclated construction phases of the project If variadons in the subsurface condifions aze observed at that time, a qualificd engineer would be abte to provide additional geotechnical engineering recommendadons to the wntractor��d design team in a timely manna as the project construction progresses. � i i 1 ; i J-1443,022604 � � 7 aa. i
