About the Program - An Essential Step for Reducing Flood Damage

The Floodplain Mapping Program was a joint initiative by the federal and B.C. governments to provide information to help minimize flood damage in British Columbia. The program identified and mapped areas that were highly susceptible to flooding. These areas were designated as floodplains by the federal and provincial Environment Ministers.

Designated floodplains are subject to development restrictions. Crown agencies such as the Canada Mortgage and Housing Corporation do not support development on designated floodplains unless adequate floodproofing measures are taken. Local governments may impose further restrictions.
