Scope: where restrictions apply

Restrictions commonly cover activities in regulated areas: filling, grading, construction, alteration of watercourses, development within floodplains, and interference with wetlands or shorelines. Developers should determine whether a property lies in an NPCA regulated area or a municipally designated natural heritage overlay and check applicable zoning and site-plan controls.

Start early: pre-consult with NPCA and City Planning before submitting detailed designs.
