Water Supply Reserve Account - Grant Application Form Form Revised May 2007 Summit County plans to store its share of the 150 acre-foot first enlargement right, the, 53.4 ac-ft of Windy Gap water exchanged to Old Dillon Reservoir, and additional water rights that may be decreed for storage in the Reservoir, for the benefit of Summit County interests, including water users participating in its augmentation plan decreed in Case No. 95CW122. Enlarging old Dillon Reservoir will require a USFS Special Use Permit, a U.S. Army Corps of Engineers 404 permit (wetlands issues), a review by the Summit County Planning Department (and possible permitting) and various intergovernmental agreements describing the relationships between Dillon, Summit County and Silverthorne. Summit County, Dillon and Silverthorne have engaged (through IGA with Summit County) the assistance of the Colorado River District to help advance the project. Currently the Colorado River District provides project management and cash flow buffering. This consists of facilitating the project formulation discussions between Summit County, Dillon and Silverthorne; leading the discussions with the permitting agencies; formulating and evaluating project alternatives; engaging consultant services where necessary; and, paying bills related to project development with reimbursement coming from Summit County. Summit County receives reimbursement from Dillon and Silverthorne for their part of the related project costs. In 2008 the ODR group plans to complete the NEPA environmental permitting required for both the USFS Special Use Permit and the USACE 404 permit. The project will be designed and put out to bid during the winter of 2008-2009. If all permits are obtained by spring of 2009, the group plans to start construction in April or May of 2009. The project should take one summer construction season to complete. To date the overall cost of the Old Dillon Reservoir Enlargement project through the IGA with the Colorado River District has been about $190,000. As the project moves into 2008 and 2009 more substantial activities will be required and expenditures will increase dramatically. The budget for permitting and engineering activities in 2008 is $500,000 and the budget for construction activities in 2009 may approach $7 million. The work for which this grant is requested is specifically to help fund the NEPA and permitting components of the work and also to fund preliminary engineering work including a wildland hydrology study, probable maximum flood study and a dam break analysis. Summit County does not have any TABOR issues with regards to this grant since the Summit County voters passed a general revenue retention measure years ago. 7
