Why The Flood Management Strategy Initiative?

The Lower Mainland Flood Management Strategy (LMFMS) initiative is aimed at the creation of a region-wide strategy to reduce flood risk and improve the flood resilience of communities along the lower Fraser River and south coast — from Hope to Richmond and from Squamish to White Rock.

Who is Involved in the Flood Management Strategy?

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, First Nations and non-governmental and private sector entities in the region. The LMFMS is an opportunity for decison-makers to work collaboratively on flood management.

Participants share information, fill knowledge gaps, enhance communications, build consensus, identify regional priorities and inter-dependencies, identify and advance projects of regional benefit and explore cost-sharing solutions.

Collaboration is important since a regional consensus on a flood management strategy can identify shared solutions and a compelling case for action at all levels.

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.
