2.0 FIELD ENGINEERING/SUPPORT <br /> The Ditch and headgate were initially inspected by Louden and Telesto on September 16, <br /> 2013 and again on October 3, 2013. While Louden selected a contractor, Telesto <br /> developed an initial damage inventory and repair guidance summarized in an October <br /> 16th, 2013 letter (Appendix A). Appendix A, Figure 1 provides the locations and <br /> overview for the majority of the damages to the Ditch. Telesto's safety team prepared a <br /> Hazardous Waste Awareness program for the contractor due to the high potential for <br /> hazardous materials that could be encountered in the post-flood area(Appendix B). <br /> The headgate structure was buried by flood debris, which initially prevented a complete <br /> damage inventory of the structure. Once the contractor was selected, debris and sediment <br /> removal from the Ditch was initiated. After debris had been removed from the headgate <br /> and the flood waters receded, a second damage inventory of the headgate, diversion <br /> structure, and Ditch was completed on October 21, 2013. On November 1, 2013, Telesto <br /> provided Louden and the contractor with a supplemental damage inventory and repair <br /> guidance summary letter for the headgate,diversion structure,and Ditch(Appendix C). <br /> Once all repairs were complete and the Ditch was deemed suitable to carry water, an <br /> initial performance test was completed. Telesto and Louden completed a final inspection <br /> on November 11, 2013. Before and after photos of the repairs are shown in Appendix D. <br /> The following sections summarize the damages and repair work for each structure. <br /> 2.1 Headgate <br /> Appendix A Photo 1 shows the pre-flood headgate, diversion, and surrounding fill. <br /> Appendix A Photo 2 was taken as the flood started when the surrounding fill was still <br /> intact. Appendix A Photo 3 was taken September 16, 2013 just after the flood water <br /> receded. Based on the inspections of the Ditch's headgate the following major damages <br /> were observed: <br /> • Large debris piles <br /> • Rock, gravel, and loam soil abutments on the downstream side of the headgate <br /> were washed out <br /> Louden Irrigating Canal and Reservoir Company 2 Telesto Solutions,Inc. <br /> r:Ilouden_ditchllouden_dachlprorhicis120131loodlengrneerrngrecItheriirouoisfin m_kaeriia4ouo_mwaen_as_rontticreafood P®rfnrild January 2014 <br />
