Materials resulting from this removal will be hauled from the permit area to a county- <br /> approved landfill or off-site salvage. Likewise, during excavation and regrading, any <br /> trash encountered will be hauled off to a county-approved landfill. Trash includes, but is <br /> not limited to, culvert pieces, downed and abandoned electrical lines, cable and <br /> miscellaneous metal. <br /> Earthwork will consist of all excavation, filling and topsoiling associated with reclaiming <br /> the site. Excavation will occur in the borrow areas and will include the removal, <br /> preparation (grizzly or screening) and stockpiling of rock to be used in the surface drains <br /> and the removal and transportation from the borrow areas of all other materials for <br /> slope reduction. The materials to be excavated are unclassified. Excavation in the <br /> borrow area will be performed until sufficient fill quantities satisfy the maximum <br /> 2:1(horizontal:vertical) slope performances for those areas needing fill. No additional <br /> allowance above the price bid will be made on account of any of the material being <br /> oversized, wet or frozen. The borrow area will be regraded to a maximum 3H:1V slope. <br /> Filling will include the placement of fill against the cut slopes to the specified maximum <br /> slopes. No special compaction is required however fill will be uniformly placed in one- <br /> foot lifts and uniformly tracked-in by the equipment placing the fill. Large rocks that are <br /> not used for drainage control purposes will be placed in stable clusters on the surface at <br /> locations directed by the Project Manager where they best blend in with the landscape. <br /> When rocks are piled in clusters, earth fill will be placed such that sufficient soil will be <br /> intermixed with the rock for planting shrubs and trees by others. The final surface <br /> configuration will approximate the overall pre-mining topography. Except for those <br /> slopes discussed in the borrow areas, all slopes will not exceed a 2H:1V. <br /> Following grading, all disturbed areas will blend in with the undisturbed areas outside <br /> the limit of the affected area. Topsoils will be excavated from the delineated stockpile <br /> areas and placed on the final contoured surfaces of the slopes, waste borrow areas, and <br /> all other areas previously disturbed during the mining operation. This includes all areas <br /> within the previously mined or otherwise disturbed permit area as indicated on the <br /> drawings. All areas receiving topsoil which are compacted will be required to be <br /> scarified to a depth of six inches (6") immediately prior to topsoil placement. Topsoil <br /> will be placed to a minimum thickness of six inches (6"). Topsoil will be uniformly <br /> placed in six-inch (6") lifts and uniformly tracked in by the equipment placing the soil. <br /> Priority areas for topsoiling are areas closest to State Highway 160, with priority <br /> lessening further to the north away from the highway. Compaction will be accomplished <br /> up and down slopes so that the track-machine grouser marks are parallel to contour. <br /> Measurement and Payment <br /> There will be no measurement for payment. Payment for this task will be reflected in a <br /> lump sum bid under Item 2 on the Bid Schedule. This lump sum bid will cover payment <br /> of all costs for excavation, transport, and placement of the wastes and topsoils. Payment <br /> shall be as this task is completed and approved by the PROJECT MANAGER. <br /> Payment for this task shall be made only for that amount shown under Item 2 of the Bid <br /> Schedule. Any or all incidental costs incurred by the CONTRACTOR shall be reflected <br /> in each Bid Item or shall be paid at the CONTRACTOR's expense. <br /> 6 <br />
