Ward 11 News: Riverbank Stabilization Project Construction along Riverdale Avenue

  • Share

Ward 11 official website

The City of Calgary Water Resources will begin construction late March 2017 on the Riverdale Phase II upstream project to replace the retaining wall. 

The 100 metre retaining wall located on the west side of the Elbow River, next to Riverdale Avenue, will be replaced with an engineered solution, designed by a multi-disciplinary design team including engineers, biodiversity experts, concrete fabricators and an artist. 

The new retaining wall will both stabilize the bank and support biodiversity with features such as cow-parsnip stalks embedded in the concrete will form tunnel habitats for solitary bees, ledges and overhangs to accommodate nesting birds, and cavities that will provide space for trees to grow. 

The retaining wall will be a concrete and steel system, using steel pilings to hold concrete slabs in place, and built to facilitate natural overgrowth. 

Two backflow valves will be installed at the storm outfalls E48 and E49. Water Resources will continue working on the 100 metre live grading downstream to complete the project in May 2017. This is work that started last year. 

Construction Impacts:

  • Construction sire access is planned at Riverdale Avenue.
  • Construction schedule to begin in March 2017 and will take approximately 3 months to complete.
  • Detours on pathways are anticipated from March 15 to June 30. See here for information on pathway closures​
  • A portion of the restoration area will be used as a staging area, and will be fenced off for construction access only.
  • 17 trees will be removed, and replaced by 2, 924 plants on site
  • There will be some construction noise from machinery and crews throughout the project during construction hours: 7 am to 7 pm Monday to Sunday. 
  • A plywood barrier will be installed to reduce noise from the equipment and construction.
