<br />. <br /> <br />. <br /> <br />. <br /> <br />INTRODUCTION <br /> <br />Purpose and Scope <br />This Floodplain Information Report was prepared to provide supporting documentation for the <br />approximate loo-year floodplain boundaries shown on the Town of Grand Lake FIRM, dated <br />January 1, 1986. The FIRM was prepared using approximate floodplain mapping techniques. <br />Engineering information was not provided by FEMA to support the approximate floodplain <br />delineations Little Columbine Creek and Tonahutu Creek shown on the FIRM. This FIR provides <br />limited engineering information to fulfill that need. <br /> <br />This FIR includes: <br /> <br />1. Authorization for the report and its purpose and scope; <br /> <br />2. Study area description including information on the community, the watershed, any known <br />flooding history/flooding problems, previous studies and projects, and community response to <br />the CWCB designation and approval process; <br /> <br />3. Description of hydrologic and hydraulic information; and <br /> <br />4. Floodplain management program. <br /> <br />Authorization <br />The CWCB has certain statutory responsibilities relating to the designation and approval of <br />floodwater runoff channels or basins as follows: <br /> <br />... "to devise and formulate methods, means, and plans for bringing about the greater <br />utilization of the waters of the state and the prevention of flood damages therefrom, and to <br />designate and approve storm or floodwater runoff channels or basins, and to make such <br />designations available to legislative bodies of cities and incorporated Towns, to Town <br />planning commissions, and to boards of adjustment of cities, incorporated Towns, and <br />counties of this state"..., Section 37-60-106(1)(c) of the Colorado Revised Statues (CRS). <br /> <br />A CWCB designation and approval of current floodplain information is needed for the incorporated <br />areas of Town of Grand Lake, Colorado. The CWCB has prepared this FIR as a means of <br />designating Town of Grand Lake's FIRM so that the community can better implement its <br />floodplain management program. <br /> <br />1 <br />
