Landslide in Lévis: Residence Under High Surveillance Following Rockslide Event

Residents of Lévis are on high alert after a rockslide struck a residential property on Rue Saint-Laurent. The incident, which occurred on Wednesday evening, has prompted emergency services and city officials to maintain a strict surveillance perimeter to ensure the safety of the community.

Emergency crews were dispatched to the 4174 Rue Saint-Laurent address around 5:00 PM following a citizen’s report. While authorities recommended a precautionary evacuation of the home, the residents chose to remain inside, trusting in the structural integrity of their property.

The Science Behind the Slide: Freeze-Thaw Erosion

According to city spokesperson Michel Thisdel, the event is attributed to a natural geological phenomenon common in the Canadian climate. The primary cause is freeze-thaw erosion (the cycle of freezing and thawing), which weakens rock faces and leads to crumbling and instability.

This isn’t the first time the area has faced such challenges; a similar, albeit smaller, event was recorded in the same sector back in 2021. To mitigate these risks, the homeowners had previously installed protective measures, including a reinforced net on the rock wall, which likely prevented more severe damage during this latest slide.

Expert Intervention and Public Safety

To ensure a comprehensive assessment of the risk, the City of Lévis has requested a technical opinion from specialized engineers at the Ministry of Transport and Sustainable Mobility. While the city is providing oversight, it is important to note that since the affected area is on private land, the ultimate responsibility for implementing permanent corrective measures lies with the property owner.

Current efforts are focused on the following safety priorities:

n
• Road Security: Specialized teams are working to secure the roadway on Rue Saint-Laurent to prevent debris from falling onto the pavement.
• Technical Analysis: Awaiting the professional verdict from government engineers to determine the stability of the slope.
• Continuous Monitoring: City crews remain on-site to respond to any further geological shifts.

For those living in areas prone to slope instability, it is highly recommended to consult guidelines from Natural Resources Canada to understand the risks associated with geological hazards in the region.
