Eldorado Court Erosion Control and Slope Stabilization Project

Toronto and Region Conservation Authority (TRCA) has proposed to undertake remedial erosion control and slope stabilization works to provide long-term protection to essential structures near Eldorado Court, Ladyshot Crescent and Grandravine Drive, in the City of Toronto.

Project Location

The Eldorado Court Erosion Control and Slope Stabilization Project is located in the City of Toronto, northeast of Keele Street and Sheppard Avenue West. As can be seen in the below map, the project area encompasses multiple private residential properties located along Eldorado Court, Grandravine Drive, and Ladyshot Crescent and borders the ravine lands of Northwood Park.

Project Background

TRCA was initially notified of erosion concerns behind multiple ravine-side properties along Eldorado Court following the July 8, 2013 severe storm event. Flooding caused by this storm event resulted in damage to hundreds of properties across the Greater Toronto Area.

TRCA’s Erosion Risk Management Program (ERMP) offers remedial erosion control and slope stabilization works to properties affected by erosion and slope stability hazards on a priority basis and to the limit of annual funding.

In 2015, TRCA completed a slope stability and erosion risk assessment for select properties along Eldorado Court that reported damage after the July 8, 2013 severe weather event. The objective of this assessment was to characterize the extent of risk at these properties and determine whether the residential dwellings located at the top of slope were at long-term risk from the hazards of ongoing erosion and slope instability.

The results of this assessment identified multiple residential dwellings are at-risk. In 2019, following reports of additional erosion concerns near the project site, TRCA opted to expand the project’s study area and undertook another slope stability and erosion risk assessment for additional properties located along Eldorado Court, Ladyshot Crescent, and Grandravine Drive.

The results of this secondary assessment identified additional properties within the study area were also at long-term risk from the hazards of erosion and slope instability.

Based on the results from the 2015 and 2019 slope stability and erosion risk assessments, landowners whose properties are deemed to be at-risk have been offered assistance through TRCA’s Erosion Risk Management Program to undertake remedial erosion control and slope stabilization works.

Remedial works will be designed to provide long-term, low maintenance protection to these at-risk properties. Due to the limits of available annual funding and the separation between at-risk areas within the project site, implementation of remedial works will be phased with the highest risk area addressed first.

Scope of Work

TRCA completed the preliminary planning stage for this project in 2020 by identifying all at-risk areas within the project area through completion of a slope stability and erosion risk assessment. Now that at-risk areas are known, the next steps for this project include:

  1. Compiling a baseline inventory of the project area
  2. Explaining the results of the slope stability and erosion risk assessment to all participating landowners and offering remedial works to properties deemed to be at-risk
  3. Evaluating a range of alternative solutions and identifying a preferred solution for erosion control and slope stabilization remedial works for each at-risk area
  4. Developing detailed designs of the preferred erosion control and slope stabilization solution for each at-risk area
  5. Securing necessary permits and approvals for future construction works

Construction Information

TRCA is currently in the planning stages for this project and construction is not scheduled at this time. Following the development of detailed designs, this section will be updated with relevant construction information.

Public Consultation

TRCA engages with affected landowners and other interested stakeholders throughout various stages of the project life cycle to ensure that public input is provided to inform project planning initiatives. TRCA seeks public input when:

  • Explaining study results and next steps to proceed with design development activities
  • Evaluating conceptual alternative solutions to identify a preferred solution for long-term, low maintenance erosion control and slope stabilization remedial works. Public consultation is particularly important during this stage to ensure TRCA undertakes a comprehensive evaluation process.
  • Developing detailed designs to ensure that the design addresses all landowner and stakeholder concerns, including potential disturbances due to construction activities

When seeking public input, TRCA coordinates open public meetings or reaches out directly to affected landowners and stakeholders. Should you be interested in being added to the project’s interested stakeholder list and receiving updates about this project, please contact the Project Manager.
