This road transects private property owned by the Soaring Eagle Ranch and will intersect Colorado State Highway 340 (Broadway) at the existing intersection of Broadway and South Broadway (Appendix B, MP-1 and MP-2). The proposed road will cross 3 drainage ways with associated wetlands under the jurisdiction of the U. S. Army Corps of Engineers (COE). In addition to wetland crossings, some intermittent drainages will also need to be crossed along haul road (refer to Appendix B, DS-1 for wetland and general intermittent drainage crossing designs). 2.3.2 Staging and Stockpiling Sand and gravel collectively removed from phase areas will be stockpiled for crushing in the 12.3- acre Processing Site. Processed material will be screened and stockpiled according to size and grade. Graded materials will either be stockpiled at the mine site, hauled away for immediate use, or stockpiled at a different location. Produced waste rock can be used for backfill and road maintenance. Equipment that will be used in the project includes backhoes, bulldozers, front-end loaders, a water truck, road grader, rock crusher, and screens. 2-3
