Understanding and Assessing Impacts
The built environment in Montréal’s Southwest borough has faced many challenges in recent years; a victim of its attractiveness, the already dense and mineralized borough is facing significant real estate development. Combined with an increase in heat waves and torrential rain events projected in Montréal’s 2020-2030 Climate Plan, the borough is seeing increased pressures on its infrastructure and risks to its population. The Urban Planning Division team also noted that many projects complying with the greening by-law ultimately had inadequate green spaces to have a real impact on UHI or site water retention. This is why they, in collaboration with the Office of Ecological Transition and Resilience, decided to use the “biotope coefficient” model to develop a regulatory tool specifically targeting green spaces, soil permeability and biodiversity conservation.
