<br />. <br /> <br />PROJECT REPORT TO <br />THE COLORADO WATER CONSERVATION BOARD <br />FOR "THE STEWARDSHIP OF STREAM CORRIDORS <br />IN COLORADO" <br />January, 1998 <br /> <br />PURPOSE <br />The purpose of the study was to obtain input from local communities and stakeholders to guide <br />the CWCB regarding the feasibility of developing a new or expanded comprehensive approach <br />and provide financial resources for local governments and special districts to better manage and <br />address flood.related and multi-objective river issues. Colorado has undergone a significant <br />growth trend, which is expected to continue, The state has also experienced significant flooding <br />in some of its more populated areas, The successes, shortcomings, and needs resulting from this <br />combination of population growth and flood events are very valuable input to properly manage <br />and deal with Colorado's watersheds, stream corridors and floodplains, <br /> <br />. <br /> <br />LEGISLATIVE AUTHORIZATION -STATE STRATEGY <br />The Water Conservation Board, though the state wide needs assessment process is hereby <br />responding to Senate Bill 97-008, Section 9 which states: "Statewide river rehabilitation and <br />floodplain management needs inventory. The Colorado water conservation board is hereby <br />authorized to erpend up to one hundred thousand dollars ($100,000) from the Colorado water <br />conservation board construction fund to develop a scope of work and contract for services to <br />conduct a statewide inventory of river channel restoration andfloodplain management needs. <br />The findings of the needs assessment will be the basis for a proposal to determine the economic <br />feasibility of establishing a statewide floodplain management and river channel rehabilitation <br />program funded separately from the Colorado water conservation board construction fund The <br />proposed program would represent a comprehensive approach and source of funds for local <br />governments to better manage mitigation measures, stream banks and channel erosion, loss of <br />channel conveyance capacity, and loss of wildlife habitat areas. <br /> <br />COLORADO FLOOD mSTORY <br />Between July 28 and August 17, 1997, extreme flooding impacted a thirteen-county area of <br />Colorado as a result of a monsoonal storm system which stalled over the front range area. Point <br />rainfall amounts of 8.3 inches to 15 inches were recorded, An estimated $200 million in flood <br />damages resulted in the Fort Collins/Larimer County area, and an additional $50 million in <br />damages occurred in twelve other counties. Six deaths were attributed to the flooding and the <br />thirteen-county area received a Presidential Disaster Declaration <br /> <br />Stream and riverine flooding has always been, and remains to be, the greatest potential hazard to <br />life and property in Colorado, Table 1 illustrates the most damaging floods that have occurred <br />throughout the state since the turn of the century, Today, flood prone areas have been identified <br />in 268 cities and towns and in all of the 63 counties in Colorado, According to CWCB staff, <br />250,000 people are estimated to now reside in Colorado's 100-year floodplains, with property <br />valued at over $11 billion. There is a clear need for improved floodplain management efforts to <br /> <br />. <br /> <br />1 <br />
