Project Description

The extreme rainfall events of November 14 and 15, 2021 have had major impacts on highways and highway structures throughout the Southern Interior and Lower Mainland, and highway infrastructure on Vancouver Island. The events caused closures on Highway 1, Highway 3, Highway 5 (Merritt to Hope), Highway 8 (Merritt to Spences Bridge), Highway 12, and Highway 99 (30 km west of Lillooet). The flooding has pushed large debris into critical waterways and washed-out bridges and road embankments throughout British Columbia. Among the hardest hit areas was the Thompson-Nicola region. Flooding has resulted in the accumulation of various debris in rivers along Highway 8 which is located between Merritt and Spences Bridge.
Managed and funded by the B.C. Provincial Government, through the Ministry of Environment and Climate Change Strategy, the project consists of planning, removing, staging and disposing of man-made debris deposited in the rivers as a result of the atmospheric river event.

RAM’s Role

RAM is removing debris in the Nicola, Coldwater, Tulameen, Similkameen, and Fraser Rivers, all of which are provincially and federally protected. All in-stream works to remove flood debris from November 2021 must reduce the impact of sedimentation and the risk contamination.

Project Highlights

RAM is responsible for ensuring that equipment mobilized to site must be free of outside soil and vegetation to prevent the spread of invasive plant species. In addition, methodologies must comply with landowner requirements, including First Nation governing bodies. This presents a considerable timeline challenge given spring freshet presents the risk of debris being refloated. RAM and its project partners are working to remove as much high-risk debris from the rivers as possible prior to rising water levels. RAM understands climate change further increases the risk of such events occurring more frequently and that time is of the essence.
