The design schedule presented below depends on obtaining approvals from the various <br />regulatory agencies in a reasonable timeframe. We have assumed that the regulatory <br />approvals for Phase 1 will be obtained by November 15, 2011 so that construction can <br />proceed. <br />Phase 1 Design Components <br />The design of Phase 1 of the Project will consist of the following components: <br />• Geotechnical borings to establish the bedrock conditions at the upper <br />cutoff wall. <br />• Upstream cutoff wall with low water crossing and a 60 foot segment of <br />42 -inch diameter steel pipe. <br />• Placement of riprap upstream of the cutoff wall. <br />• Installation of an irrigation pump and distribution piping system for the <br />sprinkling of the riparian corridor. <br />• Construction of an 18 -inch diameter, 8 cfs HDPE bypass pipeline. <br />• Grading and riprap installation downstream of the cutoff wall. <br />Phase 2 Design Components <br />The design of Phase 2 of the Project will include the following components: <br />• Geotechnical borings along the pipeline route and in the vicinity of the <br />lower cutoff wall to determine bedrock and subsurface conditions. <br />• Sediment capture structure at the upstream cutoff wall. <br />• Construction of about 3,500 feet of the 42 -inch diameter steel diversion <br />pipeline with supports. <br />• Downstream cutoff wall and diversion flow energy dissipation basin. <br />Design Status <br />The Phase 1 design is in progress and is approximately 60% complete. An item <br />that has impacted the design schedule is that the USACE required an approved <br />Preliminary Construction Notification (PCN) for the geotechnical investigation (4 <br />holes and 2 test pits) at the proposed location of the upstream cutoff wall. The <br />reason for the PCN for the geotechnical investigation is that the project is located <br />in the proximity of habitat of the PMJM. <br />Cotter submitted the PCN for the geotechnical investigation and received <br />approval from the USACE on August 9 and field investigations were performed <br />through August 26. A final geotechnical report for Phase 1 will be completed on <br />September 22. The design of Phase 1 is expected to be finalized on October 7. <br />The Phase 2 design is also underway with details of the design of the 42 -inch <br />diameter steel pipeline in progress. Structural design will begin after the <br />3 <br />
