2019 Update

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

Study Area 39 location in the Rexdale Martingrove area has experienced recurring basement and surface flooding during extreme storms in the past.

Following consultation with agencies, City Divisions and the public, the following are the study’s key findings, accepted by the City:

15 Schedule A+ projects including:

  • New and larger storm and sanitary sewers
  • Sections of large diameter storm and sanitary sewers to provide storage during heavy rainfall events
  • Catchbasin control installation: inlet control device and high capacity inlets

Map of Study Area 39

Study Area 39 is located mainly in Ward 2.  It is roughly bounded by Rexdale Boulevard to the north, Stable Road / Rexdale Boulevard to the south, Highway 427 to the west, and Humber River to the east. It is serviced by a separate storm and sanitary sewer system.

Study Area 39 was established in Etobicoke in 2013 due to severe flooding reported during the severe rainstorm of July 8, 2013. Historic records show that this area has experienced basement flooding under severe storm events for several years.

The City hosted a drop-in event in April to review, discuss and seek your feedback on the recommended solutions for reducing the risk of basement and surface flooding and improving stormwater runoff quality in the study area.

What is a Class Environmental Assessment?

Ontario’s Environmental Assessment (EA) program 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 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.
