additional configurations and alignments will not be studied now and will be deferred to <br />future feasibility-level efforts. <br />4. Several direct meetings between Grand River, GEI staff and project stakeholders will <br />occur. It is assumed that these meetings will be on the west slope and that GEI will <br />integrate the meetings with other activities to minimize travel and other costs. <br />5. Some alternatives may not meet the entire 10,825 requirement. In some cases, it may be <br />practical and obvious as to how and which options should be combined to meet the full <br />requirement. With Executive Committee concurrence, these combined alternatives will be <br />addressed in the report. <br />6. While the alternatives are intended to meet the 10825 requirement, larger options could be <br />viewed as "stage-able" to meet other needs and discussed for each alternative. However, <br />staging will not be considered during Phase 2 engineering. <br />7. Constructability issues will be addressed at a preliminary level of detail, including: dam <br />types and materials available to build the dam; effects of materials locations on costs; <br />imported materials needed and impacts on costs; water levels, flows, and diversion for <br />construction; staging areas and access; and other similar considerations. <br />8. Grand River will be responsible for communicaring with agencies that may have an impact <br />on design and cost estimates developed by GEI. This may include the Fish and Wildlife <br />Service, power suppliers, Bureau of Reclamation, and the Federal Energy Regulatory <br />Commission. Communications are intended to develop preliminary designs and cost <br />estimates that relate to endangered fish impacts, handling of non-native fsh, terrestrial <br />mitigation concerns, cost of peak or off-peak power, impacts on Reclamation projects, and <br />licensing for hydropower. Additionally, communication with the Recovery Program <br />Management Committee will be ensured through the participation of Tom Pitts and Grand <br />River. <br />9. Flood estimates are needed to configure projects and size spillways and outlet works. GEI <br />will use readily available parametric data for PMF and 100-yr flood estimates. <br />10. Diversion facility designs will need to address intake screen requirements (velocities) in the <br />lower portions of the river (e.g. DeBeque area, Sulphur Gulch, and Roan Creek sites and <br />upstream on the Eagle and Colorado). Provisions for sediment exclusion will be <br />considered for water that is pumped. <br />11. To the extent reasonable, GEI will develop cost-storage capacity and cost-delivery capacity <br />curves so that stakeholders can consider the cost effectiveness of the options and consider <br />larger or smaller size projects. <br />12. The outlet works will be assumed to require multi-level intakes to manage water quality. <br />10825 Phase 2 Scope of Work Revised May 25, 2007 per CWCB request Page 16 <br />
