Notice of commencement - municipal class environmental assessment

Rockcliffe Riverine Flood Mitigation Project

In conjunction with the City of Toronto, Toronto and Region Conservation Authority (TRCA)

is commencing a Municipal Class Environmental Assessment (EA) to determine a preferred

riverine flood mitigation strategy for the Rockcliffe-Smythe area, in the City of Toronto. This

study will incorporate and expand on the previous flood mitigation studies completed in this

area which includes the Black Creek (Rockcliffe Area) Riverine Flood Management Class

Environmental Assessment (2014) and the recently completed Black Creek at Rockcliffe

Special Policy Area Flood Remediation and Transportation Feasibility Study (2020).

It is anticipated that TRCA, in conjunction with the City of Toronto, will undertake the Municipal Class EA process in accordance with the requirements for Schedule C projects.

This will require completion of Phases 1 through 4 of the Municipal Class EA process. Upon completion of the study, an Environmental Study Report (ESR) documenting the planning and decision-making processes will be prepared for public and agency review and comment.

The primary objective of this Class EA is to minimize riverine flood risk in the Rockcliffe

area to the extent practical with robust and low maintenance solutions, while minimizing and

mitigating potential impacts resulting from the implementation of flood mitigation measures,

and coordinating riverine flood mitigation designs with concurrent transportation, sewer and

drainage projects in the study area.

There will be public and stakeholder consultation activities over the course of the study, as

per the Municipal Class EA process. Your input will be incorporated during the planning and

design process of this project. Notices will be provided in advance of future consultation

events. For further information about the project or the planning process being followed, or
