Description:
The project objective is to permanently deactivate the Granite Creek GC14A, GC14D and GC14E spur roads to mitigate the hazard of a landslides event. The GC14 road is to be also deactivated by Weyerhaeuser, therefore, the spur roads were priorized for deactivation before they became isolated. The GC14 spur roads were identified by Weyerhaeuser Company Limited, West Island Timberlands Unit as a high priority for road deactivation because of evidence of instability problems associated with these roads, which would become an isolated liability once the GC14 road was deactivated. The GC14A road was constructed across a southerly facing slope at approximately 750 m elevation and the GC14D and GC14E roads were constructed across a northerly facing slope at approximately 800 m. The GC14A roads were previously deactivated, with a light pull back of the over steepened fill slopes. Residual fills remained, which were slumping in a number of locations and as a result this road is considered a very high hazard for a slopes failure. The GC14D road was overgrown with alder, however, many signs of slope instability were evident along sections of this road. The GC14E road was located on flat slopes, requiring removal of drainage structures only.
