Scope of Work

  • Start Date: September 2020
  • End Date: August 2021

Significant weather events, including record high lake levels in 2017 and 2019, as well as severe waves from the April 14-15, 2018 wind storm event, worsened the deteriorating condition of existing shoreline erosion control structures. The purpose of the maintenance work was to install a new armourstone revetment to provide long-term erosion control in order protect the shoreline from wind and wave activity and ensure public safety. The scope of work included:

  • 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 using existing and new stone material
  • Site restoration including tree and shrub plantings
