Quebec

Quebec was the second province to join the Flood Damage Reduction Program signing a combined General and Mapping Agreement in October 1976. Flood risk areas in approximately 250 communities have been designated using the 100-year flood. The designated areas are divided into two zones, the floodway, where further development is discouraged, and the flood fringe where flood proofed development is possible. However, there are some exceptions. With Ministerial approval, a "derogation" permits a specified project to be undertaken within a specified area of the floodway.

Sub-agreements have provided for some structural measures. Dykes and flow regulation works were constructed in Montreal. A dam and an ice retarding structure were built in Quebec City. A pumping station and dyke were constructed in Richmond. The municipalities contributed 10% towards the cost of these works.
