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 and 1970s. The park features two erosion control structures which have been monitored since 2006 as a part of TRCA’s Erosion Risk Management Program (ERMP). TRCA monitoring records show that the headland is in a failing condition. Several large scours, displaced armourstone, and slumping along an informal pathway have been identified as areas of concern along the structure.

The revetment was classified 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 made the already deteriorating condition of these shoreline erosion control structures worse.

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, including installation of Erosion and Sediment Control (ESC) measures and construction fencing, establishment of staging/stockpiling areas, removal of trees and building of access roads
  • Removal of existing stone material along the shoreline
  • Installation of a new armourstone revetment
  • Site restoration including tree and shrub plantings

Construction Information

Shoreline repair works were completed from September 2020 to August 2021. Final site restoration is scheduled to take place in late Summer to Fall 2021. Restoration will include re-seeding lawn areas and repaving of the park trail. The restoration area, highlighted in red on the map, will remain closed during this time to allow vegetation to regrow without disturbance and to ensure public safety during trail works.

Playground access will remain available for the duration of restoration activities. A portion of the trail in this area, indicated in orange on the map, may temporarily be closed for paving or equipment access during work hours (Monday to Friday, 7:00 a.m. to 4:30 p.m.). Traffic control persons will be on hand to guide vehicles along the trail during these times.

The restoration area will be re-opened once the grass has established. Crews will return to complete final tree plantings in Fall 2021, as weather conditions allow. The park will remain open during this time.

For your safety, please respect all posted signs and stay clear of the work area and equipment. Your cooperation and patience with this undertaking is appreciated.

Project Updates

October 2, 2020

Construction crews mobilized on-site this week. Site setup has begun, including the establishment of perimeter fencing, staging and stockpiling locations, tree protection zones, and erosion and sediment control measures. The playground has been fenced off to allow for continued public use outside of construction hours.

August 17, 2021

Construction crews have demobilized from site after carrying out preliminary site restoration works. The next steps include re-seeding the lawn areas, re-paving the trails, and planting native trees and shrubs, which will take place in several stages. Construction fencing will remain up around the work area in order to allow grass seed to take root. The playground will remain open.
