4 <br /> Bear Creek Project <br /> Reclamation at the Bear Creek Project Area was completed near the central/eastern portion of <br /> the Old Refuse Pile during the 1999 construction season. Approximately six acres of steep <br /> slopes were reclaimed during the course of this project. <br /> Multiple Best Management Practices were implemented in the Bear Creek Project Area, <br /> including the use of severe surface scarification prior to seeding, shrub planting, placement of <br /> slash barriers and the use of silt fence. <br /> The vegetative cover at this area is visually estimated to exceed 50%. As reported in 2000, cattle <br /> were turned into this area shortly following revegetation. In places the cattle compromised the <br /> integrity of the surface scarification pattern,resulting in minor gully formation near the western <br /> margin of the Project Area. Sediment generated from the gully formation was trapped by silt <br /> fence and vegetative slash barriers located at the base of the Project Area. The gullies were <br /> repaired in the fall of 2001 by crimping weed free straw into each of the four features, and re- <br /> establishing the surface scarification pattern at the head of the gullies. A cattle exclosure was <br /> constructed around the area in the late Spring of 2001. Because the vegetative cover is effective <br /> at minimizing erosion at the area,the silt fence at the toe of the Bear Creek slope was removed in <br /> 2001. <br /> East of Road A Project Area <br /> Reclamation construction was completed in this area during 1999. Best Management Practices <br /> implemented during and following reclamation construction included the use of severe surface <br /> roughening,placement of silt fence, construction of small earthen berms and the placement of <br /> weed free straw bales. Vegetative cover in this area was visually estimated to average 40%, well <br /> exceeding the pre-reclamation cover of 5%. The land form and vegetative cover are effectively <br /> controlling erosion in this area: Therefore the silt fence was removed and the straw bales are <br /> being allowed to deteriorate. <br /> Reclamation construction was accomplished at a steep 1.5 acre area near the easterly portion of <br /> this area. The slope, which was highly erosive, and supported virtually no vegetation, was <br /> reduced to 2.5 H : 1 V. Following slope reduction,topsoil was applied to the area, and it was <br /> then severely scarified using heavy equipment. Revegetation was accomplished, and the area <br /> was fenced to exclude cattle. During and following reclamation construction,the Project Area <br /> was protected by silt fences and straw bales placed at the toe of the slope. A temporary upland <br /> diversion was used to minimize stormwater run-on during construction, while a more permanent <br /> diversion was constructed following completion of reclamation. <br /> West of Road A Construction Area <br /> Final reclamation of this area was accomplished in 1999. Again, multiple Best Management <br /> Practices were implemented in the West of Road A Area, including severe surface roughening, <br /> construction of small ridges built perpendicular to the fall of the small hill slope at the southern <br /> portion of the area, silt fence placement and the use of weed free straw bales.
