<br />If: . <br /> <br />" <br /> <br />III. Environmental Impacts <br /> <br />A. Adverse Unmitigated <br /> <br />Ridgway Reservoir would inundate 4.6 miles of the Uncompahgre River <br /> <br />and 1,030 acres of farm and rangeland, including 100 acres of riparian <br />. . <br /> <br />habitat. Salinity concentrations in the Colorado River at Imperial Dam <br /> <br />would be increased by 2.7 mg/l because of stream depletions and salt loading. <br /> <br />B. Mitigated impacts <br /> <br />All land aquisitions and the relocation of displaced individuals <br /> <br />would be accomplished according to provisions of the Uniform Relocation <br /> <br />" <br /> <br />Assistance and Real Property Aquisition Act of 1970 and other applicable <br /> <br />Federal legislation and regulations. Construction specifications would <br /> <br />provide for landscape preservation and prevention of air and water <br /> <br />pollution. Im~:oyed flow patterns and water quality in the Uncompahgre <br /> <br />River would mitigate stream losses. Approximately 1,000 acres of private <br /> <br />rangeland would be purchased and intensively developed for wildlife habitat <br /> <br />to o~fset habitat losses at Ridgway Reservoir; and deer-proof fencing along <br /> <br /> <br />U.S. Highway 550 would preclude increases in deer-vehicle accidents due <br /> <br />to the highway relocation. Concerning cultural, historical, and archaeological <br /> <br />resources, if it were determined that avoidance of any significant resources <br /> <br />identified or located in further surveys or during construction would not <br /> <br />be possible, then all steps necessary for mitigation under 36 CFR Part <br /> <br />800 would be taken. <br /> <br />C. Beneficial <br /> <br />Residents of the Uncompahgre Valley would be provided dependable <br /> <br />water supplies for existing and future municipal and irrigation needs. <br /> <br />.
