4.6 River Rehabilitation Flood lain Management Needs Inventory <br /> g Y <br /> The Board recommends it be authorized to expend up to$100,000 from the Construction Fund ' <br /> to develop a scope of work and contract for services to conduct a statewide inventory of river <br /> channel rehabilitation and floodplain management needs. The findings of the needs assessment will <br /> be the basis for a proposal to determine the economic feasibility of establishing a statewide <br /> floodplain management and river channel rehabilitation program funded separately from the <br /> Colorado Water Conservation Board Construction Fund. The proposed program would represent <br /> a comprehensive approach and source of funds for local governments to better manage and address <br /> multi-objective river issues including floodplain management, flood hazard mitigation measures, <br /> streambank and channel erosion, maintenance of channel conveyance, and wildlife habitat areas. , <br /> 4.7 Chatfield Reservoir Reallocation Study I <br /> The Board recommends it be authorized to expend up to $300,000 from the Construction Fund <br /> to cooperate with the Army Corps of Engineers, the Urban Drainage and Flood Control District, <br /> interested local governments, and other water users,in a reconnaissance study to be conducted in <br /> 1997 for the potential reallocation of flood control storage space to municipal water supply storage <br /> in Chatfield Reservoir. <br /> The purpose of this reconnaissance study would be to analyze existing and alternative operations <br /> of the Chatfield Reservoir individually and,to the extent necessary, systematically with the Cherry <br /> Creek and Bear Creek reservoirs, in order to determine the advisability of undertaking a more <br /> detailed and more expensive investigation concerning the feasibility of reallocating storage in the <br /> 111 <br /> flood control pool of Chatfield reservoir, either permanently or on a seasonal basis, to the <br /> conservation pool for water supply purposes. The reconnaissance study will estimate potential <br /> changes to downstream flows and to reservoir pool elevations as well as the potential consequences I <br /> to water supplies, flood damages, recreation opportunities,water quality, fish and wildlife habitat, <br /> and other resources. <br /> Expenditure of the funds shall be contingent upon the Board receiving a commitment from the <br /> corps of engineers that these expenditures, and significant in-kind services provided through the <br /> board staff,along with any similar contributions by other non-federal participants,will be recognized <br /> and credited appropriately in the negotiated cost share agreement for funding and implementation <br /> of a formal feasibility study, should the Board and the Colorado Department of Natural Resources <br /> decide to proceed with that level of analysis. <br /> I <br /> CWCB FY96 Annual Report,page 28 <br />
