Riverdale riverbank stabilization

Project Summary

Before the June 2013 flood event, the retaining wall along Riverdale had reached the end of its useful life and was in a condition that made it suitable for replacement. During the June 2013 flood event the retaining wall and nearby riverbank were significantly damaged, resulting in portions along the riverbank being exposed. The restoration of the riverbank will require stabilization of the slope to protect it from further erosion. To determine the best stabilization method to use, we will test a section using a wattle fence. Should the wattle fence approach be successful we will use it in the near future or a combination of that approach with other elements. The retaining wall will be replaced with en engineered solution in 2017, and will be designed in partnership with the Watershed+ art program. More details will be provided on the retaining wall portion as they become available.

Construction Details

  • The construction site for riverbank stabilization will be on the west side of the Elbow River, located next to Riverdale Avenue near the existing retaining wall.
  • Permanent riverbank restoration will be approximately 100 metres of bioengineered stabilization (live grating) with toe protection.

Construction Impacts

  • No road closures.
  • Detours on pathways are anticipated from August 15 to November 15, 2016.
  • Construction site access is planned at Riverdale Avenue.
  • A portion of the restoration area will be used as a staging area and will fenced off for construction access only.
  • A construction fence will be placed for the duration of construction.
  • 18 poplar trees will be replaced by 4,330 plants on-site
  • There will be some construction noise from machinery and crews throughout the project.
  • Working hours will be 7 a.m. to 7 p.m. Monday to Saturday.
