Yellowquill Trail Relocation
Heavy winds, rain and hail accompanied a tornado that touched down in Long Plain First Nation in 2016, causing riverbank movement that damaged Yellowquill Trail, the main roadway through the community.
KGS Group provided engineering services for the permanent re-establishment of the roadway, completing an extensive drilling and monitoring program, slope stability analysis and assessment of potential options for remedial riverbank works versus roadway and utility relocations. We also acted as the project contract administrators responsible for all environmental approvals, geotechnical investigations, riverbank stabilization as well as the municipal design of the new road alignments.
The result was a reliable roadway that will protect the community from future erosion and potential future encroachment on community infrastructure.
Project Highlights
- 500 metres of riprap erosion protection, riverbank regrading and drainage swale construction to protect the community from the long-term effects of erosion of the lower shoreline and potential future encroachment of community infrastructure
- Realignment of 1,600 metres of asphalt roadway for the new alignment of the Yellowquill Trail
- Installation of new water main, sewer, service connections and raw water along the relocated road
- Extensive revegetation design at the site, including revegetation with native grasses, trees, shrubs, and willows
