<br />. <br /> <br />. <br /> <br />Scope of Services <br />Dry Creek Flood Control Project <br />Feasibility Study <br /> <br />February 20, 2001 <br /> <br />A. Consultant <br /> <br />For the purposes of completing this Scope of Services, the consulting engineer (Consultant) <br />shall be the firm of ECI Consultants, Larimer County (County) is the lead Project Sponsor <br />with support from the City of Fort Collins (City) and the Colorado Water Conservation Board <br />(CWCS). The maximum funding to the Consultant for this Project is $50,000. <br /> <br />B. Summary of Requested Work <br /> <br />The Consultant shall perform all necessary research, analyses, report writing, coordination, and <br />other tasks necessary to produce a feasibility study (Study) for the Dry Creek Flood Control <br />Project located in Larimer County and Fort Collins, Colorado. The purpose of the Study is to <br />present all necessary information in order to seek a loan from the CWCB for construction of the <br />proposed flood control project. A substantial amount of effort has already been expended in <br />the development of a drainage master plan and a feasibility study for this project. Additional <br />work is now required to complete the Study and to meet the guidelines and criteria as set forth <br />by the CWCS construction loan program. The final Study must be accepted and approved by <br />the CWCB construction section staff. <br /> <br />C. Project Description <br /> <br />Larimer County, in cooperation with the City of Fort Collins, has been working on a flood <br />control plan for Dry Creek. The Dry Creek watershed originates in the foothills to the north <br />and west of Fort Collins and is tributary to the Cache la Poudre River. Dry Creek generally <br />flows from north to south in unincorporated Larimer County and eventually drains through <br />the northeast portion of the City of Fort Collins. The watershed contains a significant <br />number of off-channel storage reservoirs for the purpose of agricultural irrigation. Douglas <br />Reservoir is a significant on-channel irrigation storage facility. Basin land use consists of <br />mainly of irrigated croplands, pastures, open space, and low density residential areas. The <br />most downstream portion of the basin contains pockets of more urbanized development. <br />Existing studies have already identified hydrologic and hydraulic characteristics of Dry Creek, <br />and alternative flood reduction projects have been evaluated. The proposed flood control <br />plan would reduce risks associated with a 100-year flood (1-% chance flood) along Dry <br />Creek below Douglas Reservoir and would also address local storm drainage problems. <br /> <br />During the fall of 2000, the original Dry Creek Flood Control Plan was submitted to CWCB <br />staff for review. The original feasibility study was lacking content in a number of key areas, <br />and the study did not meet the necessary guidelines and was therefore not accepted by the <br />CWCS staff. It is now necessary for the Consultant to develop an acceptable feasibility <br />study to be submitted to the CWCB staff for review and approval. The new Study will make <br />use of all prior analyses and work that have been performed to date. <br /> <br />Page 1 of 5 <br /> <br />Appendix 2 Contract C150080 <br />
