202B: A Risk-Based Approach to Climate Change Planning in the Town of Ajax

October 01, 2019

1:45PM - 2:15PM

The Town of Ajax has been impacted by several significant climatic events in recent years which have led to property damage, disruption to transportation and energy systems and economic and social impacts to the community. The ability for communities to adapt and respond to these effects is imperative to the reduction and minimization of the consequences associated with climate change. As a key component of an overall Climate Change Adaptation Plan, The Town of Ajax retained the services of Dillon Consulting Limited to develop a Community Climate Study, the outcome of which provided a GIS-based tool to assist the Town in identifying, analyzing, evaluating and ultimately managing climate change based risks. The Town of Ajax identified a need to better understand the short, medium and long term trends of three main climate change stressors (temperature, precipitation and severe weather) and the risks that each stressor might impose on the community. These hazards were observed through the lens of three community outlooks including overland and stormwater flooding, threats to the natural environment and impacts to emergency preparedness and response services. In this session, participants will learn how GIS risk models can inform risk-based decision-making, the importance of relevant and timely data in generating risk models and learn about the analysis of community risks and vulnerability to establish frameworks for climate adaptation planning.
