Water Supply Reserve Account - Grant Application Form Form Revised October 2006 5. Please provide a copy of the proposed scope of work. Please refer to Part 2 of the criteria and guidance document for detailed requirements. Attach additional sheets as needed. The proposed scope of work will be centered around collecting and analyzing additional engineering information regarding the proposed reservoirs. A matrix analysis based on the attached form will be used as a comparison tool to rank each site. This ranking system will allow the County to develop a plalll1ed approach in the development of the reservoirs based on geographic need within the County, environmental issues, water administration issues, construction costs, and geologic hazards. Funding in the amount of$52,000 is requested to develop more detailed data for each site. Much of the effort will include data searches for existing studies such as USGS information that could provide better information on issues that will need to be addressed. Additional field visits to identify technical constraints will also be performed. Clear Creek County was one of the early centers for mining in Colorado so there is a considerable amount of geologic data available, although it was targeted more toward mineral extraction. Some of this data will be recompiled to address water development. Additional data will also need to be collected for final decision making, which is outside the scope of this application. A critical component is developing more detailed cost data for construction of the dams and infrastructure to operate them. There may be opportunities to integrate these structures into the operation of existing infrastructure. This will require better site information on geologic and topographic conditions for accurate quantity estimates and a uniform cost schedule that will result in a comparative cost estimate per acre- foot. Legal issues concerning the Platte River Recovery hnplementation Program developed by the States of Colorado, Nebraska, and Wyoming and the U.S. Department of the Interior, and other environmental compliance will also be considered. Site access can be a limiting factor in some situations and may result in much higher development costs. Clear Creek County includes a considerable amount of high elevation Federal lands where some of the proposed reservoirs may be located. These require additional coordination and permitting prior to approvaL These issues will be identified in this phase of study. The deliverables will be a preliminary engineering analyses of 9 proposed reservoir sites that will outline and discuss the findings for the items listed above in a matrix and report format. A ranking system will be developed that prioritizes the list of sites using multiple criteria and various weighting scales to emphasize different aspects of the project sites. The ranking system will provide guidance to the County for further studies that may be necessary and input as a master plan for moving forward. This work may also be used toward due diligence requirements in the development of the conditional water rights. Applegate Group, Inc. will perform the analyses, with consultation from Vranesh and Raisch, LLP. Qualifications for both firms are provided with this application. A detailed budget by activity, level of effort and rates, as well as a project schedule including key milestones is also attached to this application. n:\04143 clear creek county bill placer reservoir\cwcb water supply reserve account grant\2006-2007 grant application form 3.14.07 .doc 6
