The City has completed a Municipal Environmental Assessment (EA) Study for the Black Creek Sanitary drainage area, which stretches from north of Finch Avenue down to the Rockcliffe-Smythe neighbourhood. The key recommendations from the study include a major sewer upgrade in the Rockcliffe Court area that will significantly reduce basement flooding.
The purpose of this major City infrastructure project is to achieve the following:
reduce surcharge levels the Black Creek Sanitary Trunk Sewer (STS) during wet weather events
reduce combined sewer overflows (CSO) discharge to the Black Creek watercourse
reduce stormwater infiltration and inflow into trunk sewers
The following are key recommendations from the study:
install two new sanitary trunk sewers and a new combined storage tank and tunnel in the vicinity of Rockcliffe Court
complete sewer upgrades along Keele Street between Eglinton Avenue West and Donald Avenue
implement Wet Weather Flow reduction measures along the existing Black Creek STS
The study has been completed and is now open to public comment until February 5, 2020 to the Ontario Ministry of Environment, Conservation and Parks. Please click here to view the notice of completed study.

I am very pleased to see the positive impact of this project on the Rockcliffe-Smythe area. This Drainage Improvement Study is independent of the planned TRCA/City of Toronto flood mitigation projects for Rockcliffe and will bring additional protection from basement flooding in the area with the installation of a new combined storage tank and tunnel at Rockcliffe Court.
