Objective 2: Implement Stream Corridor Restoration Plan <br />Task 4: Mitigate Storm Water Runoff <br />During September 2007, storm water runoff on 5 miles of the road system in the project <br />area was mitigated using Best Management Practices: grading, rolling dips, and <br />vegetation of eroded areas. The purpose was to disconnect the disturbed areas of the <br />road and direct the drainage over vegetated areas to prevent sediment from entering the <br />creek. <br />Task 5: Relocate Roads out of the Creek <br />The Upper Creek Restoration Project was completed in September 2007 and consisted <br />of realigning Carnage Creek and Forest Route 286E to relocate the road out of the <br />creek. Best Management Practices included installing rolling dips for cross drainages, <br />excavating a new stream channel, applying boulders to block access to the stream <br />channel, and installing 2500 ft. of post and cable fencing to keep vehicles out of the <br />creek. <br />Task 6: Restore Upland Vegetation <br />Wildlands Restoration Volunteers completed the Carnage Canyon Forest Restoration <br />Project, in October 2006. Project consisted of site grading to mitigate runoff and <br />restoring vegetation at site using seed, erosion matting, straw, and soil amendments. <br />The 98 volunteer laborers and crew leaders contributed 830 volunteer hours. About <br />73,000 sq. ft. of eroded hillslopes were restored and 2780 feet of roadways obliterated. <br />Wildlands Restoration Volunteers completed the Lower Ridge Restoration Project in <br />September 2007. Project consisted of closing 7 routes, site grading to mitigate runoff, <br />restoring vegetation on the upland slopes using seed, erosion matting, straw and soil <br />amendments. The 129 volunteer laborers and crew leaders contributed 1351 volunteer <br />hours. About 61,000 sq. ft. of land was restored and 2380 feet of roadway obliterated. <br />Task 7: Construct System of Post and Cable Fencing <br />The restored project areas were protected from further degradation by installing 7,500 <br />feet of post and cable fencing. During the October 2006 restoration project, 800 feet of <br />post and cable fencing was constructed along the 1.1-mile road corridor to keep vehicles <br />from driving over the restored forest lands. Postholes were drilled with a special auger <br />attachment and steel posts were placed. Wire cable was used to connect the posts. <br />During the September 2007 restoration projects, 4200 feet of post and cable fencing was <br />constructed along the Upper Carnage Creek area to keep vehicles out of the creek and <br />in the Lower Ridge Hill areas to keep vehicles from driving over restored forest lands. <br />
