City of Pointe-Claire Stormwater Management Plan in the Context of Climate Change

In recent years, the City of Pointe-Claire has experienced several episodes of extreme rainfall, causing sewer backups, surface flooding, and a sharp increase in complaints from residents. The drainage system, designed in the 1960s, is no longer adequate to handle the volumes of water generated by these events, which are amplified by climate change. In addition, planned urban densification raises new concerns about the capacity of the existing system. Although ad hoc solutions have been implemented—such as drainage protrusions and rain gardens—their implementation has been opportunistic, without overall planning. The project aims to develop a methodology for creating a stormwater management plan (SMMP) adapted to new climate realities, based on a case study of the City of Pointe-Claire.

This project will also enable the City of Pointe-Claire to adopt a proactive and integrated approach to strengthening its resilience to climate change. The benefits include better investment planning, reduced damage costs, and a tangible improvement in citizens’ quality of life. It will also support municipal objectives in the areas of the environment, governance, and ecological transition.
