<br />The opportunity may now exist to construct certain flood and <br />erosion control measures which will mitigate future flood risks. <br /> <br />The proposed Colorado Highway No. 55 bridge design is for a <br />50-year flood discharge - 44,000 cfs. The 100-year discharge is <br />68,000 cfs. To utilize these bridge capacities, upstream levees <br />and dikes must be installed to direct flood flows to the bridges. <br /> <br />Due to the present flow direction of the South Platte River, <br />it is essential that the three existing left bank (north) <br />deflector dikes be reconditioned. These deflector dikes will <br />keep the river in its present alignment and will direct the river <br />and floodwaters to the Highway No. 55 bridges, The right bank <br />(~outh) has erosi6n protection which was installed by the <br />Colorado Division of wildlife. <br /> <br />In addition to the implementation of the structural measures <br />as outlined in this report, the Town'of Crook and Logan County <br />should continue its participation in the National Flood Insurance <br />Program which makes flood insurance available to individuals and <br />businesses. Individuals should be advised on the benefits of <br />implementing flood proofing measures on structures and dwellings <br />located in the floodplain. It is essential that floodplain <br />management practices be implemented to reduce future flood risk <br />within the community and surrounding areas, <br /> <br />LFL/bj <br /> <br />~ <br /> <br />-14- <br />
