Lower Mainland Flood Management Strategy
In 2014 the Lower Mainland Flood Management Strategy (LMFMS) initiative was launched to better protect communities along the lower Fraser River and coast — from Hope to Richmond and from Squamish to White Rock. Participants in the LMFMS have responsibilities or interests related to flood management and include the Government of Canada, the Province of British Columbia, Lower Mainland local governments and several non-governmental entities in the region.
Phase 1 of the LMFMS development process was completed in May 2016. Phase 2 is now underway.
What are Phase 1 Results?
Phase 1 work included an analysis of BC Lower Mainland flood scenarios, a regional assessment of flood vulnerabilities, and a review of current flood protection works and practices in the region.
The results show that there is significant risk of a large-magnitude flood in the Lower Mainland, and that the risk is projected to worsen over the next 85 years, both in terms of flood frequency and size, because of sea level rise and other projected impacts of climate change. If a major Fraser River or coastal flood were to occur between now and 2100, it would trigger losses estimated at $20 to 30 billion, which would be the largest disaster in Canadian history.
Phase 1 shows the critical importance of a regional strategy and a major investment in flood mitigation. The costs of a major flood event far outweigh the costs associated with effective flood mitigation.

JUNE FLOOD WORKSHOP — PRESENTATIONS AVAILABLE
A workshop was held on June 22, 2017 to explore the history of flood management in the Lower Mainland, regulatory issues for flood protection works, ecological issues and different possible approaches to flood mitigation.
The workshop drew over 70 participants, including members of the Joint Program Committee for Integrated Flood Hazard Management, members of the LMFMS advisory committees, First Nations leaders and staff, and federal, provincial and local government staff having responsibilities relevant to flood management.
For a look at workshop speakers and presentation slide decks, see Phase 2 Resources.
The Planning Institute of BC has presented a 2017 Silver Award for Excellence in Research and New Directions in Planning to the Lower Mainland Flood Management Strategy (LMFMS) initiative.
The presentation was made in Prince George, with Theresa Fresco accepting on behalf of the Fraser Basin Council, which is the LMFMS program manager.
