Announced by the Ministry of Environment and Climate Change, by Emmanuella Lambropoulos, Member of Parliament for Saint-Laurent, and by Alan DeSousa, Mayor of Saint-Laurent, this innovative project aims to increase the capacity of the stormwater network and reduce overflows into the Rivière des Prairies during heavy rains, while also integrating nature in urban environments to mitigate the effects of heatwaves and enrich local biodiversity.

The project includes three components:

The expansion and modernization of the permanent Noroît reservoir and the surrounding areas through phytotechnology will increase its capacity while adopting natural solutions for water management.

The addition of a retention basin in Midtown Park, which will provide an alternative to the direct runoff of rainwater, favoring natural infiltration to reduce pressure on the piped network.

The pursuit of the Saint-Laurent biodiversity corridor aims to facilitate the movement of species, improve the resilience of ecosystems, and help mitigate heat islands, making spaces more comfortable for residents.

This corridor fits within a logic of ecological connectivity between natural environments, parks, and green spaces in Montreal.

These ecological measures play a key role in reducing flood risks and contribute to water preservation in a sustainable context.
