Revitalization of Papineau Avenue

Optimizing urban water management

next project

Université de Montréal/City of Montréal New Outremont Campus

The City of Montréal is undertaking full reconstruction of a 2km stretch of Papineau Avenue.

This pilot project is shaping future city standards for low impact development and rainwater management. New green infrastructure helps relieve pressure on the untouched sewer system, in line with the initial objective of tackling frequent overflows caused by heavy rains.

Innovative landscaping, including planning for more than 1.2km of bioretention basins and grassy swales, has optimized stormwater management and biodiversity enhancement. Nearly 40,000 plants, including 286 trees, were added to the site. The project enables treatment of approximately 10,000 m3 of stormwater each year and 80% of suspended solids to be removed from treated water.

The project design permitted experimental tracking of the system’s performance for three years following the completion of work. This research project is in collaboration with Polytechnique Montréal and Université de Montréal.
