An online map atlas and document library has been developed to identify environmental values and features along the lower Fraser River and coastal foreshore areas – in the context of flood hazards and flood management.
The Lower Mainland Flood and Environment Atlas was developed as part of the Lower Mainland Flood Management Strategy. This atlas contains flood extents for the Lower Mainland for select flood scenarios along with a range of environmental values and features along the lower Fraser River and coastal foreshore areas. The atlas is a resource when decision makers are considering potential environmental benefits (and adverse impacts) of floods as well as flood risk reduction projects or policies. The flood levels shown on this portal are based on the 2015 Analysis of Flood Scenarios and mapping from the 2016 Lower Mainland Flood Vulnerability Assessment.
