Arrondissement de Saint-Laurent has taken into consideration the risks caused by heavy rains in the planning of our developments since the 1980s. In a context where episodes of heavy rainfall like those we witnessed on July 10 and August 9 this year are likely to become recurrent and intensify over the years as a result of climate change, it is critical to take the necessary measures to mitigate their consequences. Saint-Laurent continues its efforts to support its citizens in these recurring situations.

Among other things, the adopted resolution requests that Ville de Montréal:

• Provide a diagnostic report on the causes of the backflow and flooding of the Leduc, Notre-de-Dame-de-Grace and Décarie-Raimbault collectors serving the borough.
• Continue the improvement of public infrastructure to better respond to the increasing intensity and frequency of torrential rains.
• Re-prioritize the Leduc retention structure project by adding it to its 2025-2034 Ten-year capital works program.
• Take action with the provincial government to expand eligibility criteria for the General Financial Assistance Program Regarding Disasters so that those affected by the flooding that occurred in the summer of 2024 may receive compensation.

With its notice of motion, the borough is freezing the granting of permits for new buildings with basement dwellings. This measure will enable the borough to continue its reflection on the matter as part of climate change adaptation measures.

Lastly, a notice of motion was issued at the September 3, 2024, meeting to adopt certain regulatory provisions aimed at protecting dwellings against flooding, including by allowing the backfilling of driveways on properties with a counter slope where this is possible.
