<br />rigorous application of existing erosion control techniques could <br /> <br /> <br />substantially reduce potential soil erosion; however, special attentIon <br /> <br />would have to be given to road design, surface water runoff control, <br /> <br />and prompt mulching and planting of disturbed areas. <br /> <br />Additional mitigation of soil impacts beyond .best management <br /> <br /> <br />construction practices would be required. The cost of stabilizing <br /> <br />slopes and providing so11 erosion control could range from $500 to <br /> <br />$8,000 per acre. However, very difficult reclamation conditions could <br /> <br />cost as much as $17,900 per acre. <br /> <br />Wildlife. Potentially significant short-term impacts to elk <br />calving and other high-value areas could occur during project construc- <br />tion. The intrusion of construction activities and crews into elk <br />habitat would displace elk to more inaccessible and undisturbed areas. <br />Displacement effects would last during construction sod probably for 2 <br />to 4 years thereafter. Increased road access into currently remote <br />areas would facilitste increased recreational pressure on wildlife <br />resources, especially big game. Increased human disturbance would be a <br />potentially significant long-term impact. Wildlife mitigatIon options <br />could include timing construction activities to minimize elk/human <br />conflicts in suspected elk calving and other critical areas and pre- <br />venting unrestricted public vehicular access to project service roads. <br />The cost to implement these measures would range from $100 to $1,000 <br /> <br />per acre. <br /> <br />Visual Resources. Long-term degradation of scenic quality and <br />views within the Eagles Nest Wilderness and the Blue River Valley would <br />create significsnt adverse impacts to visual and esthet ic resources. <br />Visual degradation would occur from viewpoints both inside and outside <br />the Eagles Nest Wilderness. Signif icant scenic degradat ion would be <br />vJ.sible from Colorado Highway 9 (a major route between Dillon and <br /> <br />17 <br />
