The Study
The City of Toronto has initiated a Municipal Class Environmental Assessment (EA) study to identify the methods for controlling eight combined sewer overflows (CSO) and stormwater outfalls discharging into the Scarborough waterfront along Lake Ontario and one storm sewer outfall discharging into Massey Creek. The aim of this study is to improve water quality in Lake Ontario and make our beaches healthy for swimming.
This project was recommended in the Wet Weather Flow Master Plan (WWFMP), adopted by the City in 2003 to provide an integrated work program for managing wet weather flow.

Background
The study area is bound by Victoria Park in the west and Brimley Road in the east and sandwiched between the CN Rail in the north, and Lake Ontario shoreline in the south. This area is served by a mixture of combined, partially separated storm and sanitary sewers. There are six CSO outfalls which discharge into the lakefront at Fallingbrook Drive, Warden Avenue, Birchmount Road, Lakehurst Drive, Kennedy Road and the Scarborough Bluffs.
In the 1980s and 1990s, separate storm sewers were constructed in the majority of the study area thereby reducing the volume and frequency of the combined sewer overflows and eliminating basement flooding in many areas. Although much sewer separation has been done, combined flows are still large and hydraulic surcharging and basement flooding occurrences are avoided mainly by means of triggering many large overflows, or spillovers to the storm sewer system.
The Process
A Municipal Class Environmental Assessment (Class EA) is required for this project. The Class EA will be done in accordance with the requirements set out in the Municipal Class Environmental Assessment (June 2000) document. The Class EA process includes public and agency consultation, an evaluation of alternative solutions, assessment of the impacts of the proposed solution and identification of measures to mitigate any environmental impacts.
Public Open House #1
An Open House was held on Monday June 16th, 2008 at Birchmount Park Collegiate Institute to present an overview to the study, identify potential options the team will be considering and outline the next steps in the process. Comments are invited and requested by June 23rd, 2008. View the meeting material:
Public Open House #2
A Public Open House was held on Monday October 5, 2009 at Birchmount Park Collegiate Institute. The purpose of the meeting was to present recommendations to reduce combined sewer overflows and stormwater discharge into the Scarborough Waterfront along Lake Ontario and to minimize basement and surface flooding with the study area. Comments are invited and requested by October 19, 2009, View the meeting material:
Public Open House #3
On Tuesday June 8, 2010 a third Public Open House was held at Birchmount Park Collegiate. The purpose of the meeting was to present the study's recommendations and design concepts for underground combined sewer overflow storage facilities. These storage facilities are required to store and treat combined sewer overflows that would otherwise be discharged directly to Lake Ontario.
