Flood Risk Reduction Project in Baie-Saint-Paul

EF 2025-26 · 2026-02-13

Résumé
In order to achieve the objective of mitigating the risk of natural flood disasters, the project has four elements (1) Rehabilitation of the east wall/dike (2) Rehabilitation of the west wall (3) Resilient redevelopment of the river (4) Shoreline stabilization. For the first element (1), since a portion of the wall gave way during the 2023 floods, it is imperative to repair this structure. The event also showed that the wall was not high enough for water levels like the one on May 1. The structure will also be raised. The final shape will be either a wall or a dike or a combination of these two shapes. It should be noted that this structure protects the Saint-Joseph/Ménard neighbourhood, which includes nearly 200 properties as well as a provincial road, Route 362. For the second element (2), since a portion of the wall collapsed during the 2023 floods, it is imperative to repair this structure. This structure protects the residences and businesses of Saint-Jean-Baptiste Street, which is the city's main street and heritage street. It should be noted that the subsidence of this structure could cause landslides and damage to properties that the structure protects less and less. For the third element (3), it is essentially a question of optimising the hydraulic section of the river, i.e. the space available for flow. This work is necessary because sedimentation over time has limited this space, increasing the water level and therefore the risk of flooding. Also, the wheelbase of the train bridge piers downstream of the section also creates a narrowing of the flow space that may have exacerbated the water level. Thus, work to redevelop the riverbed along the entire urban section will mitigate the risk by reducing the water level during flooding. This work, although oriented towards the reduction of natural risk, will also be relevant and interesting from an ecological point of view. Indeed, this part of the project will make it possible to give back space to the river and to rehabilitate river spaces. The work will be carried out according to a hydrodynamic design that respects the natural morphology of this type of watercourse. Other banks are at risk of erosion. Stabilization is necessary on these banks. All three elements of the project are intertwined and thought out in a global and coherent way. The hydraulic study will integrate this entire strategy into the evaluation of the project components.

Description (French)
Afin de réaliser l’objectif d’atténuer le risque de catastrophe naturelle d'inondation, le projet comporte quatre éléments (1) Réhabilitation du mur/digue est (2) Réhabilitation du mur ouest (3) réaménagement résilient de la rivière (4) Stabilisation de berges. Pour le premier élément (1), puisqu’une portion du mur a cédé lors des inondations de 2023, il est impératif de réparer cette structure. L’évènement a aussi permis de constater que le mur n’était pas assez élevé pour des niveaux d’eau comme celui du 1er mai. La structure sera aussi rehaussée. La forme finale sera soit un mur ou une digue ou une combinaison de ces deux formes. Notons que cette structure protège le quartier Saint-Joseph/Ménard qui comprend près de 200 propriétés ainsi qu’une route provinciale, la route 362. Pour le deuxième élément (2), puisqu’une portion du mur s’est affaissée lors des inondations de 2023, il est impératif de réparer cette structure. Cette structure protège les résidences et les commerces de la rue Saint-Jean-Baptiste qui est la rue principale et la rue patrimoniale de la ville. Notons que l’affaissement de cette structure pourrait provoquer des glissements de terrain et dommages aux propriétés que la structure protège de moins en moins. Pour le troisième élément (3), il s’agit essentiellement d’optimiser la section hydraulique de la rivière, soit l’espace disponible pour l’écoulement. Ces travaux sont nécessaires puisque la sédimentation au fil du temps a limité cet espace, augmentant le niveau de l’eau et donc le risque d’inondation. Également, l’empattement des piliers du pont de train à l’aval du tronçon crée aussi un rétrécissement de l’espace d’écoulement qui a pu exacerber le niveau de l’eau. Ainsi, des travaux de réaménagement du lit de la rivière sur l’ensemble du tronçon urbain permettront d’atténuer le risque en diminuant la hauteur d’eau lors de crue. Ces travaux, quoiqu’orientés sur la diminution du risque naturel, seront aussi pertinents et intéressants d’un point de vue écologique. En effet, cette partie du projet permettra de redonner de l’espace à la rivière et de réhabiliter des espaces fluviaux. Les travaux seront réalisés selon un design hydrodynamique qui respecte la morphologie naturelle de ce type de cours d’eau. D'autres berges sont à risque d'érosion. Une stabilisation est nécessaires sur ces berges. L’ensemble des trois éléments du projet sont imbriqués et réfléchis d’une manière globale et cohérente. L’étude hydraulique intégrera l’ensemble de cette stratégie dans l’évaluation des composantes du projet.
Expected Results
The project will protect the Saint‑Joseph/Ménard neighbourhood, which includes nearly 200 properties as well as the provincial road 362, the residences and businesses along Saint‑Jean‑Baptiste Street, and will prevent landslides and damage to the properties protected by the existing structures.
Expected Results (French)
Le project protégera le quartier Saint-Joseph/Ménard qui comprend près de 200 propriétés ainsi qu’une route provinciale, la route 362, les résidences et les commerces de la rue Saint-Jean-Baptiste, et prévenir les glissements de terrain et dommages aux propriétés protegés par les structures existantes.
