Understanding and Assessing Impacts
This case study addresses the climate impacts risks and vulnerabilities related to stormwater management in the Township of Nipigon due to increased heavy rain and melting events, which are anticipated to intensify with climate change. Recent events such as the heavy rain of 2012, the hail and wind storms of 2013, the extreme cold temperatures of 2013, 2014 and 2015, and the severe heat waves of 2015 have highlighted the need to be prepared for and adapt to climate change. In 2015, the Township of Nipigon completed a stormwater master plan that identified opportunities for the improved management of stormwater. The township is particularly interested in exploring the use of LID strategies that rely on natural infrastructure (e.g., soils and plants) and natural processes (e.g., transpiration, filtration) to both reduce peak runoff during rain and melting events, and to improve stormwater discharge quality, particularly by reducing suspended solids. Doing so will reduce the negative impacts of stormwater discharge at its outfall. A primary intention of this project was to explore and demonstrate the utility of LID in the management of stormwater.
