Climate is a moving target ‐ we know the world is warming, we know the sea level is rising but we are deeply uncertain about the pace of this. Current standard practices for engineering design and current benefit‐cost based decision frameworks weren’t developed for this new reality. If we continue to use standards based methods (e.g. a 0.2% design flood) and simple decision frameworks (e.g. benefit/cost) we are setting ourselves up to fail. The success of traditional infrastructure, designed on old principles, is typically binary…it works until it fails. In this presentation, we propose common‐sense principles and ideas to create a paradigm shift in design thinking. These principles will lead to a more robust future where infrastructure is useful and effective under multiple climate futures and benefits communities both pre- and post-shock (i.e. if the flood never comes will the infrastructure still provide benefit?).
The participants will also learn how to step-through a process that supports this approach, including details on why a climate based risk assessment is key both to infrastructure design, but also more importantly to infrastructure planning (i.e. sizing a pipe appropriately for climate vs. deciding whether a pipe is the best tool to meet community needs). We will also provide ideas on how to conduct a useful risk assessment given climate uncertainty, data gaps and limited methodologies based on field experience conducting risk assessments in Canada.
