throughout the cut and fill area. Three species, Colorado blue spruce, Douglas fir and <br />Engelmann spruce were planted in approximately equal quantities. <br />As required by our Stormwater permit, a number of Best Management Practices were <br />employed during and after construction: Silt Fence or earthen berms were used at the toe <br />of the slope as earth work operations were conducted. After construction was complete, <br />approximately one thousand feet of silt fence was installed near the toe of the slope to <br />provide treatment for any runoff which may develop from the reclaimed area. Timber <br />and shrub slash generated during site preparation work was used to create sediment <br />barriers which were placed at likely drainage points at the toe of the reclaimed slope. <br />Segments of silt fence and straw bales were used at a few locations near Coal Creek and <br />Dutch Creek where drainage from the reclaimed area may occur. <br />Reclamation of the area east of the Dutch Creek Diversion was completed as :part of the <br />Bear Creek Project. Reclamation activities included removal of the topsoil stockpile <br />placed here in 1998, final grading of the excess earthen materials stockpiled during <br />construction of the Dutch Creek Diversion in 1998, topsoil application to the entire area, <br />surface roughening and revegetation. Grading created a very roughened and uneven <br />surface with a slight grade to the north and west, in order to encourage slow runoff to <br />either Coal or Dutch Creek. Following grading and topsoil application, the surface of the <br />area was severely ripped using a dozer. This created a highly disrupted ground surface <br />which should minimize the volume of runoff which may report to the adjacent streams. <br />At the southern most portion of this area, a very wide swale was constructed from about <br />the former location of the head of the old flume. The Swale parallels the old flume <br />footprint, and extends about two hundred and fifty feet to the north. The purpose of this <br />Swale is, in the event that a large debris flow were to block the Dutch Creek Diversion, a <br />flow path for the Dutch Creek overflow would be available for water to drain to Coal <br />Creek without cutting into the Old Refuse Pile. After ripping, the area was fertilized, <br />seeded and mulched. <br />Other reclamation activities in this area included demolition of the Dutch Creek Flume, <br />and reclamation of the Old Refuse Pile access road by alternately pulling the outslope in, <br />or by severely roughening the road surface using a light trackhoe. Two small drainage <br />channels were constructed on the Old Refuse Pile above the 009 pond. These channels <br />were designed to convey water to the pond in order that the water not cascade down the <br />face of the pile, as it has in the past. These channels were excavated, hand raked, seeded <br />fertilized and lined with C-125 liner. <br />Silt fencing was placed around the perimeter of the area east of the Dutch Creek <br />Diversion, above and adjacent to Coal Creek and Dutch Creek. Any drainage which <br />originates from this approximately five acre area will pass through the silt fence prior to <br />entering the adjacent creeks. <br />A total of twelve acres were reclaimed during the course of this Project, for a total cost of <br />$246,420. <br />7
