• Coastal cities around the world are facing same challenges of sea level rise
• Major floods in the Lower Mainland are expected to increase in magnitude and frequency (Fraser Basin Council report)
• Vancouver is exposed to sea level rise along the coast, Burrard Inlet and Fraser River

Fraser River Freshet 2018 • May 2018 the Fraser valley experienced freshet flooding that was
more significant than previous years • Freshet flooding occurred due to unseasonably high temperatures and
a higher than normal snowpack in the Fraser River Basin • The City of Vancouver opened the Emergency Operations Centre in
response to the event and carried out daily monitoring activities of the shoreline
• The City made several public announcements about possible swift water conditions along the Fraser River
• No flooding or erosion was observed within the City of Vancouver, along the Fraser River

Sea Level Rise • Climate change is driving sea level rise and a 50cm
increase is projected for 2050 and 1 metre by 2100 • Province has advised municipalities to prepare for 1
metre by 2100 and 2 metres by 2200.
