The Master Plan takes into account certain environmental constraints on land use. Some stem from natural phenomena, such as flood-prone areas, or morphological characteristics, such as the Saint-Jacques escarpment. Other restrictions are related to intense urban activities that are often incompatible with housing, as in the case of airports, quarries and overhead power lines. The Master Plan calls for action to control construction in light of these constraints.

The Plan sets forth one action relative to the environmental constraings:
