Constraint zones
Areas subject to landslides
In Saint-Lazare, there are mainly four areas prone to landslides: a residential area along the Quinchien River (parts of Vallée-Chaline, Chemin Sainte-Angélique, Rue Duhamel, Rue Legault and Route de la Cité-des-jeunes) and three agricultural areas (small parts of Chemin Fief and Chemin Saint-Louis). In total, just over 100 properties are affected.
What is a landslide?
It is the downward movement of a mass of soil, under the effect of gravity, causing all or part of a slope (sloping ground). A slip can occur if the equilibrium conditions of a slope are altered naturally (erosion) or artificially (backfill, backfill). Most landslides begin primarily in the presence of an embankment, particularly on stream clay banks. In 40% of cases, they are caused by human activity, which is why it is important to consult the Environment Service, avoid inappropriate human intervention, monitor warning signs and advise the City if necessary

Following the completion of stabilization work in the Vallée‑Chaline area, the Ministère des Transports du Québec (MTQ) has updated mapping to reflect the changes made. This government mapping must be embedded in the regional and municipal By‑law. The City of Saint-Lazare must apply this mapping as well as the corresponding regulatory provisions as required by the provincial government.
The new mapping shows that the areas potentially exposed to highly retrogressive landslides have been significantly reduced as a result of the stabilization work.




As stipulated by the Loi sur l’aménagement et l’urbanisme , the Assemblée publique de consultation on draft by‑laws No. 1139 and 1140 was held on Tuesday, September 6, 2022 at City Hall. The purpose of these draft by‑laws is to ensure concordance with By‑law No. 167‑25 amending the revised land use plan of the MRC of Vaudreuil-Soulanges by inserting the new mapping of areas potentially exposed to highly retrogressive landslides in the Vallée‑Chaline sector. The changes made to the By‑law were explained at this meeting.
By‑law No. 1139 and 1140 have been adopted during the council meeting held on Tuesday, September 13, starting at 7:30 p.m.
The City invites citizens to contact the Urban Planning Department by phone at 450‑424‑8000, extension 242, or by email at urbanisme@ville.saint‑lazare.qc.ca before starting any work or projects in order to ensure that the latter respect By‑law targeting affected areas.
