Section 37-60-106(1) (c), Colorado <br /> <br />existing homes must have the lowest floor level above the <br /> <br />elevation of the 100-year flood, <br /> <br />Revised Statutes 1973 authorizes the Colorado Water Conservation Board <br /> <br />Non-residential construction must meet the same standard <br /> <br />" d' d <br />to eSlgnate an approve storm or floodwater channels or basins, and to <br /> <br /> <br />make such designations available to legislative bodi~s of cities and <br /> <br /> <br />incorporated towns, to county planning commissions, and to boards of <br /> <br /> <br />adjustment of cities, incorporated towns, and counties of the state." <br /> <br />or be flood proofed to that level. <br /> <br />The 1968 act benefits owners of structures already in the flood-prone <br /> <br /> <br />areas by providing insurance that had been unavailable through private <br /> <br /> <br />companies. The act created a cooperative program of insurance against <br /> <br /> <br />flood damage by the private flood insurance industry and the federal <br /> <br />government. <br /> <br />In 1974 the General Assembly added a new article 7 to chapter 106, <br />Colorado Revised Statutes 1963, (re-coded as article 65.1 of title 24, <br />C.R.S. 1973 [1975 Supp.]), relating to state and county planning <br />commissions. This new article (H.B_ 1041) provides for the designation <br /> <br />and regulation of areas and activities of "state interest." Section <br /> <br />FLOOO PLAIN MANAGEMENT <br /> <br />24-65_1-201, includes natural hazard areas, such as flood plains, as <br /> <br />areas of state interest. A flood plain is defined in the act as being <br />"an area adjacent to a stream, which area is subject to flooding as a <br /> <br />result of the occurrence of an intermediate regional flood ~ and which <br /> <br />The need for adequate fJoodways to carry the flows of Cottonwood Creek <br /> <br /> <br />has been recognized by town officials and county planners. Subdividers <br /> <br /> <br />and developers are required to submit proposed storm drainage plans to <br /> <br /> <br />the county commissioners for approval. In the past, drainage plans have <br /> <br /> <br />been prepared singularly or on a plat-by-plat basis. Information con- <br /> <br /> <br />tained in this report will be useful in developing a master drainage <br /> <br /> <br />plan for the study area. This report provides the outline of flood <br /> <br /> <br />hazard areas on large scale maps specifically for this purpose. <br /> <br />area thus is so adverse to past, current, or foreseeable construction or <br /> <br />land use as to constitute a significant hazard to public health and <br /> <br />safety or to property." <br /> <br />~ The Intermediate regional flood is the 100-year frequency flood. <br /> <br />16 <br /> <br />15 <br />
