Toronto and Region Conservation Authority (TRCA), in partnership with the City of Toronto, has completed shoreline protection work within the Miles Road End Parkette.
This work will protect the parkette against the hazards of shoreline erosion and address public safety concerns.
Project Location
The Project Area is located within Miles Road End Parkette at 4 Miles Road, Etobicoke, Ontario. The area of concern was the entire shoreline within the parkette, located southwest of Humber Bay Park West on the Lake Ontario shoreline.
The west section of the Project Area consisted of miscellaneous concrete and rubble material, including slabs of concrete loosely stacked, that provided informal shoreline protection. The east section of the Project Area consisted of a storm water outfall and cobble shoreline.
Despite the presence of the concrete and cobble material, backshore erosion was evident throughout the shoreline within the Project Area.
Scope of Work
- Construction Start Date: March 2023
- Construction End Date: June 2023
High lake level events in 2017-2019, as well as extreme weather conditions including the April 2018 ice storm event, exacerbated structural deficiencies observed within the parkette and posed a risk to public safety.
The goal of the project was to replace the ad hoc and informal shoreline protection with a more robust and effective structure to provide erosion resistance and to better preserve adjacent usable park space.
The scope of work for this project included the following:
-
- Site setup, including tree removals, installation of Erosion and Sediment Control (ESC) measures and construction fencing, installation of tree protection, and the establishment of staging/stockpiling areas and construction access route
-
- Removal of the existing material and construction of a revetment through placement of armourstone in a sloped configuration
-
- Placement of cobble stone berm northeast of the storm water outfall to reinforce the shoreline
-
- Site restoration and demobilization
The erosion protection structure was designed to absorb wave impact and be more resilient to changing to lake levels.
