IMPLEMENTATION SCHEDULE The construction activities at Kern Reservoir are proposed to begin with the drawn down of the water surface in mid-September 2002. Dewatering and excavation activities will follow as soon as possible. The goal for the 2002-2003 irrigation off-season is to: I) excavate and haul material for use on the neighboring development, 2) construct the slope liner, and 3) remove approximately 400,000 cubic yards of sand and gravel to the nearby mine for processing. Additional excavation and haul of aggregate materials is scheduled to occur during the 2003-2004 and 2004-2005 off-seasons. SOCIAL. ECONOMIC. AND PHYSICAL IMPACTS The project will provide full storage capability for the reservoir. The reservoir has filled with silt due to the inlet of the New Cache la Poudre Ditch. The inlet of the ditch is being relocated as a part ofa separate project done by the Town of Windsor and Lot Holding Investments to further eliminate the silting problem. As a result, the reservoir will have many positive social impacts, as it will allow for additional storage capacity; a healthier ecology for fish, birds, and other wildlife; increased recreational uses for the citizens ofthe Town of Windsor; some storm water uses; and other irrigation purposes. The project will have a positive economic impact of providing the historical storage capacity for irrigation water to the shareholders' agricultural lands, as well as other irrigation uses. Due to the silting problem, the historical storage has not been possible in the past. The project will have no significant impact once construction is complete. PERMITTING The Kern Reservoir and Ditch Company must obtain authorization from the Colorado State Engineer's Office for the proposed modifications, only if the reclamation is within 200 feet ofthe current dam structure. At this time, the plan is not to reclaim any portion of the reservoir within the 200-foot buffer area of the dam. The local office of the U.S. Corps of Engineers has been consulted, and it has been determined by Terry McKee, that this reservoir is not under the jurisdiction of the Corps. Larry Rogstadt, with the Colorado Division of Wildlife has been consulting several times in regard to any wildlife habitat on the reservoir and careful consideration will be taken during the reclamation process. A letter has been sent to the Colorado Division of Minerals and Geology (DMG) to determine if a permit is required. It is our understanding that a Declaratory Order is the appropriate permitting process with the DMG. Other permits regulating the particulars of construction activities (i.e., construction dewatering, roadway access, dust, etc.) will be the responsibility ofthe selected contractor to obtain. INSTITUTIONAL CONSIDERATIONS An agreement with the New Cache la Poudre Ditch Company is in the process and the only other contracts, agreements, or Court actions necessary for the construction of the project, are a loan contract with the CWCB, a construction contract with the construction company, and an engineering contract with Rocky Mountain Consultants, Inc.
