This map locates the areas of high current and low current of the Ottawa and Gatineau rivers. The low-current zone corresponds to the part of the floodplain, beyond the limit of the high-current zone, that can be flooded during a 100-year recurrent flood. The high-current zone that corresponds to the part of a floodplain that can be flooded during a 20-year recurrent flood. The floodplain corresponds to the space occupied by a lake or a watercourse during a flood period within the meaning of the Policy for the Protection of Coastal Shores and Floodplains.

The land use and development plan puts forward a frame of reference aimed at better knowing, protecting and promoting heritage. The data available in this set mainly comes from the mapping of sections 2.1, 2.3 and 3.1 of the Urban and Urban Plan of Montreal, namely adaptation to climate change, territories of ecological interest, the Green and Blue Grid, the Green and Blue Grid as well as constraints and nuisances. In January 2025, map 15.1 — Wetlands of Interest was added to the Diagram. Resources related to this map are now available: - Wetland of interest to protect or restore - Wetland protection area - Wetland of interest for sustainable use - Coastal wetland or flood zone This urban planning and development plan for the agglomeration of Montreal outlines the main parameters that will guide the Montreal agglomeration council in decisions relating to land use planning in the coming years. From a perspective of sustainable development, this document guides decisions that shape the territory in order to promote compact and greener neighborhoods, increase public and active transportation, support the economic dynamism of the agglomeration and highlight areas of interest.
