About the Flood Management Strategy Initiative

The Lower Mainland Flood Management Strategy (LMFMS) initiative was aimed at creating a region-wide strategy to reduce flood risk and improve the flood resilience of communities along the lower Fraser River and south coast. Phase 2 of the work wrapped up in 2023 with completion of several technical projects and two final reports.

Phases of Strategy Development

PHASE 1 2014-2016

Lower Mainland
Flood Risks

Phase 1 reported on:

  • Coastal and Fraser River flood scenarios
  • Projected economic impacts
  • State of flood mitigation

PHASE 2 2016-2023

Informing a Flood Strategy

Phase 2 highlights:

  • Hydraulic Modelling and Mapping in BC’s Lower Mainland
  • Lower Mainland Flood Risk Assessment
  • Flood and Environment Atlas
  • FloodWise website
  • Lower Mainland Dikes: An Analysis of Freeboard and Vulnerability

Final reports:

  • Pathways to Action for Flood Risk Reduction and Resilience
  • Synthesis of Technical Analysis


Next Steps

The Province of BC will follow up on the Pathways to Action report with other orders of government. The Pathways report encourages:

  • Government-to-government work to co-create flood risk reduction actions, plans and/or strategies in alignment with BC Flood Strategy
  • Early emphasis to safeguard Lower Mainland critical infrastructure and essential services

Flood Scenarios Explained

A Lower Fraser 2D Flood model was developed in Phase 2 of the Lower Mainland Flood Management initiative to provide a better understanding of how flood waters could be expected to move across the land, to create flood hazard maps, and to evaluate different flood scenarios and mitigation efforts.
