The plan would reduce risks associated with a 100-year flood (1% <br />. chance flood) along Dry Creek, address local storm draina�e problems, and would include work <br />related to an agricu(tural irrigation system. <br />Over the past 2�/z years the County's consultant conducted an en�ineerin� study to develop <br />alternatives for the Dry Creek project that culminated in a feasibility study known as the "Dry <br />Creek Flood Control Plan". Floods on Dry Creek would be controlled through construction of a <br />spillway enhancement for the Douglas Reservoir spil(way, construction of one or more detention <br />storage reservoirs, and finally construction of an outfall channel for residential flood tlows. The <br />plan has been reviewed by the Larimer-Weld Irrigation Company, the owner of Douglas <br />Reservoir, and by the CWCB. The plan has also been discussed and verbally accepted by Mike <br />Cola (DWR Division Engineer). FEMA has also reviewed the plan. <br />Implementation of the Plan requires a capital investment of approximately $5.3 million, with a <br />future request to the CWCB for a loan in the amount of $3.9 million. A final feasibility study <br />needs to be produced at this time prior to the CWCB staff and Board considering the future loan <br />request. The County will hire a qualified consulting engineer to complete the necessary study. <br />Therefore, the issue at hand is a non-reimbursable feasibility study investment to Larimer County <br />in the amount of $50,000. <br />� <br />Flood Protection • Wa[er Project Planning and Financing • Stream and Lake Protection <br />Water Supply Protection • Conservation Planning <br />
