<br />WHEREAS, detailed hydrologic information for the approximate riverine floodplains listed in <br />Table 2 but not listed in Table 4, which generally includes streams in the Denver Metropolitan area, is <br />available from drainage reports and master drainage plans produced by the Urban Drainage & Flood <br />Control District; and <br /> <br />WHEREAS, the approximate riverine floodplain information, as listed in Table 2, in said new <br />Flood Insurance Study meets all of the requirements listed under the Board's "Rules and Regulations for <br />the Designation and Approval of Floodplains and of Storm or Floodwater Runoff Channels in <br />Colorado" (2 CCR 408-1); and <br /> <br />WHEREAS, a procedure for determining hydrology information for approximate floodplains <br />of reservoirs, lakes, ponds, local storm drainage areas, and overflows from irrigation ditches and <br />canals has not been established by the CWCB; and those floodplain areas may not be designated as <br />approximate floodplain information without a procedure for estimating lOO-year peak flows, and <br />therefore the local government should require that a detailed hydrologic and hydraulic study be <br />performed by a professional engineer and submitted by the developer or the development proponent <br />prior to any floodplain development in those cases; and <br /> <br />WHEREAS, hydraulic determinations for the approximate floodplains listed in Table 2 were <br />prepared by FEMA using approximate hydraulic techniques approved under the Board's "Rules and <br />Regulations for the Designation and Approval of Floodplains and of Storm or Floodwater Runoff <br />Channels in Colorado" (2 CCR 408-1); and <br /> <br />DESIGNATION AND APPROVAL ACTION <br /> <br />NOW, THEREFORE, BE IT RESOLVED by the Colorado Water Conservation Board in <br />regular meeting assembled in Canon City, Colorado, this 25th day of September 2000, that it does <br />hereby designate and approve as detailed floodplain information the lOO-year floodplain delineations as <br />listed in Table 1 for incorporated communities within Adams County contained in said new Flood <br />Insurance Study dated March 16, 1995 and said new Hydrology Addendum dated September 2000, with <br />included Flood Insurance Rate Maps; and <br /> <br />BE IT FURTHER RESOLVED that the Board does hereby designate and approve as <br />approximate floodplain information the Zone A lOO-year riverine floodplain delineations as listed in <br />Table 2 for incorporated communities in Adams County contained in said new Flood Insurance Study <br />dated March 16, 1995 and said new Hydrology Addendum dated September 2000, with included Flood <br />Insurance Rate Maps; and <br /> <br />BE IT FURTHER RESOLVED that the Board does hereby designate and approve as <br />approximate floodplain information the Zone A lOO-year non-riverine floodplain delineations listed in <br />Table 2 provided that the County requires a detailed floodplain analysis to be performed by a registered <br />professional engineer and submitted by the development proponent prior to approving any new <br />development proposals in those areas; and <br /> <br />5 <br />
