Flood Management

Located on the north bank of the Fraser River and the Eastern tip of Lulu Island, the City of New Westminster covers twelve square kilometres, of which five are within the flood boundaries indicated on the Ministry of Environment Floodplain Map. A 'floodplain' is defined as "typically dry land adjacent to a watercourse that is susceptible to flooding". Based on the Fraser River Flood Profile developed by the province, the city created a Flood Susceptibility Map which delineates the areas that can be potentially flooded during the spring Freshet (mountain snow-melt).

Planning

Floodplain Management

Both Queensborough and sections of the mainland are included within the provincial floodplain. Currently development within the flood susceptible lands is controlled by either the Subdivision and Development Process.

In the 1960’s a perimeter dyke was built on Queensborough protecting approximately 350 hectares. The city is currently in the process of developing a floodplain strategy for the city to assist with future flood protection planning and existing dyke upgrades.

Emergency Planning

On an annual basis the City prepares for the possibility of flooding and closely monitors the annual snow pack and river conditions on the Provincial River Forecast Center website. In the event that flood conditions are predicted the City has developed an emergency plan that identifies locations that require temporary protection measures, city staff responsibilities, and monitoring plans.

Provincial Emergency Program

A Flood hazard plan for BC has been prepared and is updated regularly by the Provincial Emergency Program to ensure that an effective strategy is in place to address emergencies. The Flood plan fosters cooperation with multiple organizations focusing on public safety, infrastructure and property protection and managing the aftermath of events. See the Provincial Emergency Program Website for more information.

Residents and businesses must be prepared to be self sufficient for at least 72 hours or more following a major emergency. To assist with preparation the provincial government has prepared a “Get Prepared” document.

The highest freshets to date occurred in 1894, 1948, and 1972. View photos and statistics on past floods at Environment Canada.

Houseboat Preparations

The Fraser River Port Authority advises that it is up to each tenant, boat/houseboat owner to determine the necessity to relocate. If relocating, it must be ensured that the new location is able and willing to accept the vessel. It is recommended that mooring lines be regularly checked, especially as the water rises, to ensure that they are still holding appropriately. Further flood information and tips can be fount at the Port Metro Vancouver website.
