This isn’t news to BCREA, or to many stakeholders around the province. Unfortunately, this risk is very real for much of BC, as demonstrated by the most recent report from BCREA.
Only 21 per cent of BC communities and First Nations have access to a floodplain map that’s ten years old or less, according to the BC Floodplain Map Inventory Report, published in October by BCREA. Nearly 31 per cent reported they have no access to floodplain maps at all.
Floodplain maps support decision making by showing risks to existing and proposed developments and infrastructure, and help support resilient growth and emergency planning. To be effective, though, the maps must be updated regularly to reflect changes in land development, the environment and climate.
The BC Floodplain Map Inventory Report identifies the BC floodplain maps created or updated in the last ten years. It also describes the public availability of maps, availability of supporting data, and challenges and opportunities communities have experienced with floodplain mapping projects.
The report results suggest that better information about floodplain maps, guidelines for their development, data standardization, and stronger funding mechanisms will all improve the state of floodplain mapping in BC. Better floodplain maps will make communities, First Nations and the entire province more resilient.
The BC Floodplain Map Inventory Report is the most recent completed project coming out of BCREA’s Floodplain Maps Action Plan, which was developed in 2013.
