Lower Mainland Flood Management Strategy
Phase 1 of the LMFMS development process was completed in May 2016: see Phase 1 below for key findings.
Phase 2, focused on developing a long-term strategy, is now underway (2017-2020).
Phase 2 Progress Updates
The Flood Strategy Briefing offers progress update on Phase 2:
The Fraser Basin Council – as facilitator of the initiative – will send the briefings regularly to LMFMS funders and other participating entities via chief administrative officers and executives, as well as to members of the Joint Program Committee for Integrated Flood Hazard Management and other advisory committees.

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.
