"to devise and formulate methods, means, and plans for bringing about the greater utilization of the waters of the state and the prevention of flood damages therefrom, and to designate and approve storm or floodwater runoff channels or basins, and to make such designations available to legislative bodies of cities and incorporated towns, to county plamling commissions, and to boards of adjustment of cities, incorporated towns, and counties of this state...," Section 37-60-106(1)(c) of the Colorado Revised Statues (CRS). A CWCB designation and approval of current floodplain information is needed for the incorporated areas of the Town of Otis, Colorado. The CWCB has prepared this report to permit the designation of the approximate floodplain information contained in the Town of Otis FIRM, as revised by the CWCB, so that the community can better implement its floodplain management program. Purpose and Scope This Floodplain Information Report (FIR) was prepared to revise the Town of Otis FIRM, dated August 19, 1985, and to provide supporting documentation for the approximate 100-year floodplain boundaries shown on the revised FIRM. FEMA did not provide engineering information to support the approximate floodplain delineations shown on the FIRM. This report provides limited engineering information to fulfill that need. This FIR includes: I. Authorization for the report and its purpose and scope; 2. Study area description including information on the community, the watershed, any known flooding historylflooding problems, previous studies and projects, and community response to the CWCB designation and approval process; 3. Description of hydrologic and hydraulic information; and 4. Floodplain management program.
