MacDonald Bridge to 9 Ave SE - Elbow River bank restoration

In the June 2013 flood, a portion of the river bank along the Elbow River between MacDonald Bridge and 9 Avenue S.E. Bridge saw significant bank scour.  The restoration of the riverbank requires stabilizing the slope and protecting it from future flood events.

About the project

Approximately 150 metres of riverbank was impacted on the east side and 60 metres on the west side.

A combination of riprap (large rock) along the toe (base) of the river bank and vegetation such as brush mattresses and live fascine will be used to restore the riverbank, stabilize the slope and re-establish the vegetation for a natural looking bank. The project will also incorporate root wads and woody debris to re-establish fish habitat that was destroyed during the flood.

The erosion protection will protect public infrastructure such as a major commuter pathway, a walking trail and several residences from continued erosion which could cause further bank instability.

Construction on the east side of the river will occur April 6 to June 15, 2015 and construction on the west side will occur sometime between July 15 and Sept. 15, 2015. Landscaping will be completed by Oct. 15, 2015.

Impact to citizens

Citizens near the delivery site will see and hear construction activities. Traffic on 7 Street will be affected during repairs on the west side of the bank. Flag personnel will help guide construction traffic in and out of the site. Road disruptions will be communicated through, 311 and social media.

A pathway detour will be in effect during construction. Only one side of the riverbank will be worked on at a time to ensure pathway access during both phases. Pathway users will be detoured to the pedestrian walkways on the MacDonald Bridge and the 9 Avenue S.E. bridge. The temporary pathway closures and detours will be communicated through pathway signs and
