i <br />Fish Creek Soil Investigation <br />• RECOMMENDATIONS <br />Soil core descriptions, surface vegetation, and topographic relief suggest that the <br />existing AVF boundary along Fish Creek in Section 11 should be relocated as shown on <br />Map 1. Approximately 800 feet of proposed road corridor in Section 11 could be <br />relocated up-gradient approximately 100 feet to follow an existing abandoned <br />farmstead access road and avoid potential wetland soils along the stock pond shoreline. <br />The remaining 6,314 feet of access road corridor from the fence line at the south end of <br />the stock pond to the shaft pad have no soil limitations. Soil coring and geologic <br />stratigraphy strongly suggest that the entire 1.8 acre ventilation shaft pad is located on a <br />suitable upland Winevada soil series formed over fractured sandstone bedrock parent <br />material. While the previous AVF boundary (shown in green on Map 1) is located <br />within the southwest corner of the shaft pad, the revised AVF boundary (shown in red <br />on Map 1) lies outside of the proposed shaft pad location. Southern and western <br />portions of the 500-foot buffer that overlay the Fish Creek channel contain AVF and <br />wetland soils (Map 1). No soil mapping activities were performed on the west side of <br />the railroad corridor within the 500-foot buffer area since pad and shaft construction <br />activities will not cross the railroad tracks. If construction activities are limited to the <br />ventilation pad and northern and eastern halves of the buffer area, no AVF or wetland <br />soils will be affected. <br />• Soil core descriptions, surface vegetation, and topographic relief suggest that the <br />existing AVF boundary along Fish Creek in Section 17 should be relocated as shown on <br />Map 2. The 2,930 feet of access road corridor in Section 17 from the existing fan pad at <br />the south east end to the shaft pad at the north east end has no soil limitations. At its <br />current location, the 1.8 acre ventilation shaft pad is bisected by a narrow perennial <br />drainage channel which contains wetland soils (Map 2). If mining conditions are <br />suitable, the fan pad and its associated buffer area could be moved south approximately <br />150 feet to avoid these wetland soils and potential storm drainage. <br />U <br />Habitat Management, Inc. 4 OI/06/04 <br />
