IPRRIP - ED OFFICE MEMORANDUM <br />1 -1 <br />PHASE V — BIDDING & CONSTRUCTION (12 -36 Months) <br />o Bidding usually takes about three months. Construction time will vary with <br />weather. Typically, construction of large reservoir projects is staged through two <br />construction seasons. <br />Other factors like inclusion of recreation facilities, hydropower, and design of return flow <br />facilities will impact the cost and timeline. <br />The above timeline is not even close to meeting the milestone in the Program document. Here is <br />my opinion of a feasible compressed schedule for the reservoir planning process including <br />critical path tasks. It still looks like it is going to take close to two years to get through the <br />feasibility process. <br />• PHASE I — PREFEASIBILITY (Jan 2009 — August 2009) <br />• Hydrology, sedimentation, and reservoir routing — January through early March <br />• Preliminary geotech — mid March <br />• Structure design, water quality, transportation impacts, cost estimating — mid <br />April through mid July <br />• Wetland & T &E windshield survey — late June <br />• Landowner meeting — mid July <br />• Final Report — mid August <br />• PHASE II — FEASIBILITY (September 2009 — September 2010) <br />• Aerial Mapping — November 2009 <br />• Hydrology, sedimentation and reservoir routing — December 2009 — mid March <br />2010 <br />' o Intermediate Geotech — mid March 2010 <br />o Cultural Resources Survey— March or April 2010 (crops out) <br />o Wetland Delineation —Early July 2010 <br />' o Final Report — September 2010 <br />Some of reconnaissance the work that Boyle is going to do may allow us to compress further but <br />' the only big time savings would be if we had the project areas flown in the spring of next year at <br />roughly the same time as the geotech was happening. That would reduce downtime at the end of <br />next summer while we would have been waiting for the detailed topographic survey. The issue is <br />that until we have a good idea of structure size and capacity, it is difficult to determine how <br />much area needs to be surveyed. <br />a <br />
