If you are a single-family homeowner, a condominium property manager or street-level business, we want to learn about the source of your flooding issues!

 

Study Area 44, located within the Bloor Street to St. Clair Avenue/Jane Street to Don Valley Parkway area, has experienced basement and recurring surface flooding during extreme storms in the past.

A study is underway to determine the contributing factors for surface and basement flooding in the City and recommend solutions to improve the City’s sewer system and overland drainage routes in order to mitigate flooding problems.

Potential solutions may include:

  • Upsize sewers
  • Underground storage
  • New or upgrade pumping stations
  • Wet/dry ponds where space allows

Study Area 44 consists of the Lower Level Combined Sewer interceptor distributed in portions of Wards 9, 11, 12 and 14.

The sewershed is roughly located in the area bounded by Bloor Street to St. Clair Avenue/Jane Street to the Don Valley Parkway.

The Project Area (three study areas) is approximately 7,100 ha and includes Basement Flooding Protection Program Study Areas 42, 44 and 62. The Project Area is roughly bounded by Don River to the east, Keele Street to the west, St. Clair Avenue to the north and Lake Ontario to the south.

The sewershed is tributary to the Core Interceptor Combined Sewer System (also known as Waterfront Interceptor System) which includes Mid-Toronto Interceptor (MTI), High Level Interceptor (HLI) and Low Level Interceptor (LLI).

Study Overview

The City of Toronto has initiated several Class Environmental Assessment (EA) studies to identify the causes of flooding and develop solutions to reduce the risk of future surface and basement flooding before it is discharged to watercourses.

Study Areas 42, 44 & 62, located within the St. Clair Avenue, Jane/Keele Street and DVP area, has experienced basement and surface flooding during extreme storms in the past.

In response, the City of Toronto has initiated these EA studies to address flooding that originates within the City’s property such as roads and sewer infrastructure (public property).

The Process

These studies are being planned as a Master Plan in accordance with the Municipal Class Environmental Assessment process and will result in a series of recommended basement flooding remediation projects. The Master Plan will define the problem, consider and evaluate alternative solutions, assess impacts of the preferred solutions and identify measures to lessen any adverse impacts.

Public Consultation

Opportunities for public input are planned throughout the study, including an online survey, stakeholder meetings and public consultation events. Information about each study’s progress will be made available on the webpage and shared with persons who sign-up for updates.

Due to the size of the three combined study areas of approximately 100,000 properties, the study may take four years to complete.

What is a Class Environmental Assessment?

Ontario’s Environmental Assessment (EA) program Opens in new window promotes good environmental planning by determining and managing the potential effects of a project prior to implementation.

The EA program ensures that public concerns are heard. EA balances economic, social, cultural and natural environmental needs so that projects benefit Ontario.

This study is being carried out according to the Municipal Class Environmental Assessment Master Plan process. This is an approved approach to satisfying requirements of the Environmental Assessment Act specifically tailored to municipal infrastructure. The process includes identifying the problem or opportunity to be addressed, developing and evaluating a range of alternative solutions, providing opportunities for public input and identifying a preferred solution.
