In the June 2013 flood, portions of the bank along the Bow River suffered riverbank erosion. The current condition of the riverbank includes exposed banks and vegetation, damage to the pathway and gabion (rock cage) structures and loss of rip rap rock (large rock) around stormwater outfalls. The restoration of the riverbank will require stabilizing the slopes, protecting it from further erosion and restoring the pathway.
About the project
Approximately 100 metres of riverbank is damaged. The construction site is located on the south bank of the Bow River. It extends from just west of the pedestrian bridge (that crosses the river north of Bow Green Crescent N.W.) eastward to the Canadian Pacific Rail (CPR) bridge.
Restoration involves placing 100 metres of large rock at the toe of the slope and restoring the vegetation on the banks above the rock. Bio-engineering techniques including brush mattresses will be used to further stabilize the bank.
Construction will begin the week of March 30, 2015 and may take up to eight weeks.
Impact to citizens
Construction vehicles will access the site using the CPR access road that runs parallel to 69 Street N.W. Residents on 48 Avenue N.W. and 69 Street N.W. will see some increased traffic as construction vehicles access the CPR road.
Approximately 100 metres of pathway between the pedestrian bridge and the CPR bridge will be closed for the duration of the construction. The temporary pathway closures and detours will be communicated through pathway signs and calgary.ca/parks.
