2.4. Floodplain

For the purposes of this Policy, floodplain refers to the area occupied by a lake or watercourse during flood periods. The floodplain corresponds to the geographic extent of the flooded area whose limits have been identified using

— a map approved under the agreement entered into between the Gouvernement du Québec and the Government of Canada respecting flood-risk mapping applied to floodplain preservation;

— a map published by the Gouvernement du Québec;

— a map integrated into a land use planning and development plan, interim control by-law or municipal planning by-law;

— 20-year flood elevations, 100-year flood elevations, or both, as established by the Gouvernement du Québec; or

— 20-year flood elevations, 100-year flood elevations, or both, as referred to in a land use planning and development plan, interim control by-law or municipal planning by-law.

If there is inconsistency in the application of those various means and, according to the law applicable, any one of them could govern a given situation, the most recent map or the most recent flood elevation, as the case may be, recognized as valid by the Minister of Sustainable Development, Environment and Parks, is to be used to delineate the extent of the floodplain.
