Long Branch Park Major 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 Long Branch Park in order to protect against the hazards of shoreline erosion and address public safety concerns.

Project Location

The project area is in Long Branch Park along Lake Promenade at the base of Long Branch Avenue, in the City of Toronto. The area of concern includes an armourstone headland and revetment located along the north shore of Lake Ontario.

Project Background

Long Branch Park was built in the 1960s as a lake fill extension. The park features a playground, gazebo, benches, and a trail that connects to the neighbouring Len Ford Park. Erosion control structures, including an armourstone headland and revetment, were added to the shoreline in the mid-1970s to protect the park from wind and wave activity.

These erosion control structures have been monitored since 2006 as a part of TRCA’s Erosion Risk Management Program (ERMP). TRCA monitoring records show that the headland has been in a failing condition since its initial inspection in 2006. Several large scours, displaced armourstone, and slumping along an informal pathway have been identified as areas of concern along the structure.

The revetment has been recorded in failing condition since 2008 and identified as failed in 2017. The bank in this area has shown signs of active erosion, including displacement of rock material, loss of mature trees, and undercutting of the top of bank which has placed a formal park trail at-risk and presents a public safety hazard.

Recent significant weather events, including record high lake levels in 2017 and 2019, as well as severe winds from the April 14-15, 2018 wind storm event, have exacerbated the already deteriorating condition of these shoreline erosion control structures.

In 2017, TRCA retained Shoreplan Engineering Limited to develop detailed designs for repair of the armourstone headland and revetment in order to address ongoing erosion concerns. The design includes reconstruction of the shoreline armouring using both original and new rock material, with the addition of a second layer of armourstone to increase the structures long-term resilience to storm events.

Scope of Work

The scope of work for this project includes the following components:

  • Site preparation: installation of sediment and erosion control measures and construction fencing
  • Removal of existing armourstone material on headland and revetment
  • Installation of new armourstone headland and revetment
  • Site restoration including tree and shrub plantings

Construction Information

Construction is tentatively scheduled to start in late Fall 2019. Construction details will be provided before implementation begins.

Public Notices

Notices of Construction signs will be placed at the park entrances and members of the community will be updated before construction begins.

Project Updates

Update: July 26, 2019

Detailed designs have been finalized and TRCA is working to secure all remaining permits and approvals. Progress updates will be posted as construction begins.
