Phase 1 Overview
Phase 1 of the LMFMS (2014-2016) was focused on an analysis of BC Lower Mainland flood scenarios, a regional assessment of flood vulnerabilities and a review of flood protection works and practices in the region.
In Phase 1 (2014-2016) of the LMFMS, three major projects were completed:
- Project 1: an analysis of Lower Mainland flood scenarios
- Project 2: a regional assessment of flood vulnerabilities
- Project 3: a review of the state of flood protection infrastructure, policies and practices.
Two key findings emerged from Phase 1
- There is a significant and increasing risk of a large-magnitude flood in the Lower Mainland and
- The risk of flood 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.
Details on Phase 1 can be found in the Phase 1 Summary Report.
Phase 1 reinforced 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.
