Embankment stabilization in Notre-Dame-de-l’Ile-Perrot

Located in a popular residential area along the St. Lawrence River, the embakment stabilization project on Simone-de-Beauvoir Street and 150th Avenue in Notre-Dame-de-l’Ile-Perrot aimed to protect residents’ safety while preserving the integrity of the local environment. The unstable slopes and erosion of the riverbanks posed a serious threat of severe landslides with potentially catastrophic consequences. This complex project presented well-adapted technical solutions, combining safety, sustainability, and respect for environmental issues to prevent further degradation of the riverbanks and surrounding land.

Artelia was selected by the City of Notre-Dame-de-l’Île-Perrot to manage all technical aspects and government approvals for the project. Our team provided plans and specifications for temporary access roads, storm drainage for existing structures, and vegetation for the planned riprap, while incorporating green engineering techniques to ensure improved aesthetics and long-term protection of the structure. The mandate also included preparing and managing the call for tenders, supervising the work, and applying for environmental authorization from the MELCC and the Department of Fisheries and Oceans (DFO). In collaboration with local authorities, Artelia successfully completed this large-scale project and obtained the necessary ministerial decree to begin work quickly.

The solution proposed by the MTQ consisted of installing permanent riprap to stabilize the bottom of the slope and prevent erosion of the banks. Ultimately, this project required a meticulous approach, taking into account the proximity of residences and the concerns of citizens, while respecting the deadlines and budgets set. Thanks to our expertise and good management, we implemented effective solutions to secure this vulnerable area.
