Landslide Restoration on Forestry Road within a Domestic Watershed


Location: Slocan, British Columbia

Client: Slocan Forest Product Ltd.

Objective: To rehabilitate a debris flow, restore stability of the slide, and to re-establish native vegetation. To reduce sediment delivery to Springer Creek.

Springer Creek is located in the southern interior of British Columbia. Terra Erosion Control Ltd. developed and implemented a soil bioengineering prescription to rehabilitate a debris flow, which was caused by diverted water on an upper road system within a domestic watershed. The implementation of the work was carried out at the end of July 1998. The site was stabilised through soil bioengineering techniques such as; wattle fences, live gully break, live staking, and live smiles using local willow cuttings, which had been in cold storage for a period of four months. The site was re-assessed for growth during the fall of 1998 and the willow cuttings showed a survival rate of 98%. The site was then monitored again in the summer of 1999 and 2001. The results of this monitoring showed functioning structures; in addition, the live sediment trap using a wattle fence system in the lower portion of the slide successfully trapped a large amount of sediment while the vegetation was establishing.
