About 100 residents of Barnston Island, located in the Fraser River between Surrey and Pitt Meadows, have been told they should prepare to leave at a moment's notice. Residents under alert are strongly advised to have an emergency kit readily available to enable them to quickly leave their properties in the event of an evacuation order.
Right now, Barnston Island is restricted to residents, businesses and those with a family connection. Barnston Island Regional Park is also closed. Residences on Farrell Street could start to flood when the river reaches about 9.4 metres.
However, those living along the river banks are advised that the province expects the Fraser to peak at 6.6 metres at the Mission gauge next week, and further alerts and orders are possible in the coming days.
