<br />of the flood control pool in the Cherry Creek Reservoir would <br />cause diversion into the Sand Creek basin resulting in severe <br />property damage and possible loss of life. <br /> <br />( II ) The value of lands and improvement s along Toll Gate <br />and Sand Creeks is continually increasing. In 1947, a survey <br />was made to detennine the value of lands and improvements subject <br />to flooding from Cherry Creek Reservoir emergency spillway dis- <br />charges. This survey indicated that the value of IMds Md <br />developments was less than $1 million. A second survey in 1958 <br />indicated that the value of lands and developments had increased <br />to over $8 million. In 1968, the value of endangered lands and <br />developments had increased to over $86 million. <br /> <br />(5) The maximum pool level during a routing of a <br />probable maximum flood would be at elevation 5645 feet. About <br />half of the existing reservoir lands are based on an acquisition <br />line at elevation 5625 feet. The other half of the existing <br />reservoir lands are based on an acquisition line at elevation <br />5629 feet. About 8110 acres of land lie between the reservoir <br />lands and elevation 56115. Urban development is occurring on the <br />privately owned lands below elevation 56115 feet. Additional <br />development is planned in these areas. The rapid rate at which <br />the Cherry Creek Reservoir is likely to rise poses a potentially <br />severe threat to private property and human life around the <br />periphery of the reservoir. <br /> <br />(6) Upstream problems. In the Cherry Creek basin <br />upstream from Franktovn, flood plains are narrow and are <br />agricul tural in character. This area 'is sparsely populated, <br />and flood damages are limited to crop losses Md transportation <br />damages. Soil Conservation Service structures provide limited <br />flood-damage reduction. <br /> <br />(7) Downstream from Franktown, flood plains become <br />increasingly more developed. About 8,000 acres of land are <br />located within the flood plain in this reach. Historically, <br />flood damages between Franktovn and the Cherry Creek Reservoir <br />have been limited to crop losses and transportation damages. <br />Development, resulting from the expansion of Metropolitan Denver, <br />is beginning to surround and bypass the Cherry Creek Reservoir <br />and to progress southward in the basin. The total value of lMd <br />and development between Franktovn Md the Cherry Creek Reservoir <br />is estimated to be $9,000,000. <br /> <br />21 <br /> <br />~, " <br />..:.:ih,~.. <br />,,~.,. <br />
