| Abstract/Description or Keywords |
At the request of Mr. Todd Phillips, R.F.T., of British Columbia Timber Sales, Arrow Field Unit (BCTS), Sitkum Consulting Ltd. (SCL) has carried out a Terrain Stability Assessment (TSA) and Soil Erosion Assessment (SEA) for the proposed construction of the Perry Ridge North (PN) forest roads PN Mainline extension, PN 11000, PN 11030, and PN 11040. The proposed road construction is situated on the northwest side of Perry Ridge in south eastern B.C., approximately 40 km north of Castlegar, B.C. (refer to Figure 1). Access is via the existing Perry Ridge North Forest Service Road (PN FSR). The TSA was requested by BCTS based on the BCTS Terrain Stability Management Model protocols for managing terrain stability in a gentle-over-steep (GoS) scenario. The scope of the work, as requested by BCTS, is: _ to identify potential terrain stability concerns associated with the proposed forest road construction; _ to evaluate the potential spatial impacts relating to slope stability on down slope resources including private land, the Little Slocan FSR, and fish habitat; _ to make recommendations for culvert sizing and placement as well as construction methods intended to reduce the likelihood of landslides attributable to the proposed road construction; and _ to identify areas of concern with respect to soil erosion and sediment delivery associated with the proposed road construction, and to make recommendations for mitigation as appropriate. |
