Sherwood Creek-Burke Brook Fish Passage Restoration Addendum

The City of Toronto has initiated an addendum to the Sherwood Creek-Burke Brook Fish Passage Restoration, a study completed in 2006. This addendum will determine potential changes to the recommendations identified in the final report regarding the segment of Burke Brook from east of Bayview Avenue (north of Glenvale Boulevard) to the confluence at West Don River.

This study will include the outfalls, sanitary sewers and maintenance holes related to the City’s stormwater and sanitary system. This study will not examine trail conditions or recommend improvements to trails, forestry or ravine amenities.

To participate in this study and receive updates by email, please contact burkebrook@toronto.ca to be added to the project contact list.

The following components of the City’s infrastructure that will be assessed in this study include:

  • Three (3) storm outfalls
  • Ten (10) parallel sanitary sewers
  • Three (3) sanitary sewer crossings
  • Six (6) maintenance holes

Common Risks to Storm and Sanitary Sewers in Our Ravines and Watercourses

A number of severe storm events since the completion of the 2006 study have caused significant erosion within Burke Brook. The City’s infrastructure at risk of this erosion include:

  • Three (3) storm outfalls
  • Ten (10) parallel sanitary sewers
  • Three (3) sanitary sewer crossings
  • Six (6) maintenance holes

The potential risks to City infrastructure as a result of erosion:

  • Destabilizing the soil near sewers and watermains
  • Exposing or breaking previously buried sewers and watermains
  • Damage storm outfall structures, erosion control structures, watercourse bed (bottom of the watercourse), watercourse banks and aquatic habitats

Some photos that illustrate the risks include:

Study Objective

This study will investigate and analyse the stream processes and current conditions impacting the stormwater and sanitary sewer infrastructure within the Burke Brook and undertake forecasting work to help predict future scenarios and/or impacts. Solutions can then be developed to help mitigate or prevent those future scenarios and ensure local the City’s infrastructure in Burke Brook can continue to operate and service residents and businesses.

Study Process

The study will carry out the requirements for an addendum to a completed Municipal Class Environmental Assessment, ‘Schedule B’ (please contact us to request a copy). This study will carry out the following steps to complete the addendum:

  • Analyze existing conditions and identify the problem or opportunity to be addressed
  • Develop and evaluate a range of alternative solution(s) that will address the effects of unstable channel dynamics and erosion process on Toronto Water infrastructure
  • Identify preferred solutions and develop conceptual plans
  • Issue Notice of Filing

Notification to the community will be provided when a range of alternative solution(s) have been developed. The notice will include descriptions of the alternative solution(s) and request for community input and feedback.
