Primary consideration was <br />given to resolving the basin's flood problems and to removing the <br />risks associated with the Cherry 0reek Dam and Reservoir project. <br />Recreation, erosion, and sedimentation needs of the basin were <br />given secondary consideration. The following paragraphs briefly <br />discuss the potential solutions to the water resources problems <br />of the Cherry Creek basin. <br /> <br />b. Flood control <br /> <br />(1) Cherry Creek Dam and Reservoir. The solutions con- <br />sidered for either reducing or eliminating the potential hazards <br />caused by the hydrologic deficiencies of the Cherry Creek Dam and <br />Reservoir included zoning, evacuation, ilood proofing, diversion, <br />interbasin storage, and intrabasin storage. <br /> <br />(a) Zoning. The possibility of zoning those lands <br />within the Cherry Creek Reservoir below the elevation of the <br />maximum pool was considered as a solution for reducing losses <br />caused by flood storage. Portions of these lands are currently <br />developed as expensive residential properties. Other portions <br />are now zoned for residential andconunercial use and development <br />is actively underway. Zoning of the Toll Gate Creek and Sand <br />Creek flood plains as a possible solution to prevent damages <br />f'rom.the operation of the Cherry Creek Reservoir emergency <br />spillw~ was also considered. These lands are also extensively <br />developed in some areas and are presently experiencing pressures <br />for additional rapid development. Because of the amount and <br />extent of the urban improvements already present in the Cherry <br />Creek Reservoir area and along Sand and Toll Gate Creeks, zoning <br />would be an impractical solution to the flood problems. Such <br />action, if implemented without evacuation measures or flood- <br />prOOfing measures, would curtail only future levels of flood <br />lOSSeS while having little effect on the current levels of flood <br />damage. <br /> <br />(b) Evacuation. In order to mitigate damages by <br />use of evacuation, removal of development around the Cherry Creek <br />Reservoir and along Toll Gate and Sand Creeks downstream from the <br />Cherry Creek spillway outlet route would be required. Evacuation <br />of the areas around the Cherry Creek Reservoir would cost in <br />excess of $10 million unde~ existing co~ditions of development. <br />Based on the type and nature of development planned for these <br />areas and the rapid rate at which the areas are developing, <br />evacuation operations under future condl tions are estimated to <br /> <br />. <br /> <br />21, <br />
