ROTARY PEACE PARK SHORELINE MAINTENANCE PROJECT

Toronto and Region Conservation Authority (TRCA), in partnership with the City of Toronto, is undertaking maintenance works on existing shoreline erosion control structures along Lake Ontario within Rotary Peace Park in order to protect against the hazards of shoreline erosion and address public safety concerns.

Project Location

The project area is located in Rotary Peace Park at 25 Eleventh Street, south of Lake Shore Drive, in Etobicoke, City of Toronto. The area of concern is located at the southern end of Rotary Peace Park, on the north shore of Lake Ontario.

Project Background

The shoreline landform of Rotary Peace Park was built as a fill extension in the mid-1960s and includes an armourstone headland for erosion control protection. The landform has been used as a public park since its construction, and features a formal walking trail, benches, and open green space that overlooks Lake Ontario.

In 2006, TRCA began conducting annual inspections of the headland structure as a part of the Erosion Risk Management Program (ERMP). The 2006 inspection identified exposed geotextile with major displacement and voids of armourstone within the shoreline revetment. The ERMP has assessed the structure as failing since this initial inspection and has ranked it as a high priority for maintenance since 2010. Subsequent inspections have identified ongoing deterioration of the structure, including significant scouring behind the upper tiers of the armourstone wall and slumping of the revetment into the lake.

In the Spring of 2017, Lake Ontario experienced record high water levels which further exacerbated deterioration of the headland, increasing upland erosion and placing the formal park trail at-risk.

In 2013, TRCA retained Shoreplan Engineering Limited to develop a detailed design for repair of Rotary Peace Park’s shoreline armouring in order to address ongoing erosion concerns. The design includes reconstruction of the shoreline armouring using both original and additional new rock material, as well as the installation of a vegetated drainage swale to improve tableland drainage.

Scope of Work

The scope of work for 2018 includes project construction, which will involve the following components:

  • Site preparation, including installation of sediment and erosion control measures, as well as installation of construction fencing which will limit access to a portion of the park
  • Removal of existing armourstone structure
  • Installation of new armourstone revetment
  • Installation of vegetated drainage swale behind revetment
  • Site restoration including tree and shrub plantings

Construction Information

Construction is scheduled to commence June 18, 2018 pending the receipt of all required permits and approvals, and is anticipated to be completed by the end of December 2018.

Please note, to ensure public safety, a portion of the park, including trails within the limits of construction, will be closed to the public for the duration of the work. Amenities including the swimming pool, playground, and lawn bowling field are located outside of the work limits and will remain open. Please see the map below for details.
