Understanding and Assessing Impacts
The Mohawk Council of Akwesasne (MCA) is a community of approximately 12,300 people (2016) distributed over an area of 11,720 acres and governed by MCA. The community comprises three districts: Kawehno:ke (Cornwall Island, Ontario), Kana:takon (St. Regis, Quebec) and Tsi Snaihne (Snye, Quebec). MCA’s unique climate can be characterized by many storm tracks that meet in the area and they have recently experience increased summer heat, humidity, and air quality issues. Drought has also been observed in the past and projected to occur more frequently based on IPCC AR5 RCP 8.54 data. Climate data was acquired from Canadian (Environment and Climate Change Canada) and American (NOAA) weather stations and Ontario Tornado Watch. Since 1970, observed trends include rising temperatures, more frequent hot days, longer growing seasons, less snowfall and more winter rain, reduced snowpack, and earlier ice and snowmelt resulting in earlier peak river flows. Many of the MCA’s infrastructure assets were built in the 1990’s and early 2000’s and will need replacement, undergo rehabilitation, or retrofit, or will be at an advanced stage of their service lives within the time horizon selected. The purposed of this project was to assess the vulnerability of water and wastewater (W/WW) infrastructure of the MCA and provide recommendations on possible adaptation measures to mitigate identified risks.
