<br />are 13 miles of p1p1ng on the west side and 19 miles on the <br />east side of the valley. All structures in the improved system <br />would be replaced. A total of about 6,880 structures and about <br />86,000 acres of land would be affected. Wildlife measures <br />include acquisition of 4,614 acres of land for wet land habitat <br />and construction of 15 deer escape ramps along the South Canal. <br />Where field conditions warrant, more flexible lining such as <br />earth could be used and where more practical, other lining <br />measures could be implemented in lieu of concrete. <br /> <br />Plan A-2 Concrete line all canals and laterals on the east side of the <br />Uncompahgre Valley, a total of 254 miles of the system including <br />the Loutzenhizer, Selig, East, and Garnet Canal systems in addi- <br />tion to the remaining unlined reaches of the South Canal. All <br />structures in the improved system would be replaced. About <br />32,400 acres of project lands would be affected as would 3,040 <br />structures. About 2,121 acres of land would be acquired for <br />wetland habitat and 15 deer escape ramps would be constructed <br />along the South Canal. Where field conditions warrant, a more <br />flexible lining would be used in place of concrete. <br /> <br />Plan B <br /> <br />Plan C <br /> <br />Plan D <br /> <br />Plan E <br /> <br />Plan F <br /> <br />The features of plan B are identical to those of plan A-2 except <br />that plan B includes 19 miles of piping in place of open concrete <br />section. <br /> <br />Concrete line deteriorated parts of the Uncompahgre Project distri- <br />bution system amounting to about 98 miles located on both sides of <br />the valley. In addition, all structures in the entire system would <br />be replaced. About 10,000 acres of project lands would be affected <br />by development of the plan and about 829 acres of wetland habitat <br />would be required for mitigation of wetland losses. <br /> <br />Earth line 514 miles of the West, Montrose and Delta, and Ironstone <br />canal systems on the west side, and the South, Loutzenhizer, <br />Selig, East, and Garnet systems on the east side of the Uncompahgre <br />Valley. Also included are 13 miles of piping on the west side of <br />the valley and 19 miles on the east side of the valley. Concrete <br />would be placed in laterals with less than 50-c.f.s. capacity <br />exclusive of those sections to be placed in pipe. All structures <br />in the improved portion of the system would be replaced and a <br />total of about 7,600 structures and 86,000 acres of lands would <br />be affected. wildlife measures consist of acquisition of 4,614 <br />acres of land for mitigation of wetland habitat losses. <br /> <br />Earth line 254 miles of canals and laterals on the east side of <br />the valley and place pipe in 19 miles of the system. In laterals <br />with capacities of 50 c.f.s. or less, pipe would be installed in <br />place of concrete. All structures in the improved part of the <br />system would be replaced. About 32,400 acres of land would be <br />affected together with 3,040 structures. About 2,121 acres of <br />land would be acquired for wetland habitat. <br /> <br />"Future without" alternative. No salinity funds would be <br />expended. This alternative assumes that due to operation and <br />maintenance and rehabilitation and betterment programs and <br />irrigation management, some salinity reduction would occur'000915 <br /> <br />16 <br />
