Sunnyside, like the communities of Eau Claire, Chinatown, East Village and Inglewood, sits on the flood plain of the Bow River. Infrastructure is in place to mitigate flooding in Sunnyside but the risk of flood damage remains. A berm along Memorial Drive and the Bearspaw Dam upstream provide some protection but proved not enough in June 2013. The berm was breached in two areas and the Bearspaw Dam was too far upstream and the reservoir storage capacity too small to prevent this large flood.
