Riverbank stabilization and critical erosion sites

Priority riverbank restoration projects

After the 2013 Flood, more than 200 flood-related infrastructure projects requiring repairs or restoration work were identified and prioritized into critical, high, moderate and low-priority projects. Outfalls and riverbanks along the Bow River, Elbow River, Fish Creek, Nose Creek and West Nose Creek were inspected for damage. 161 outfalls along the rivers and 53 outfalls along the creeks were identified as damaged and have been prioritized for repairs.

Actions to complete all of the critical and seven high priority projects occurred prior to the 2014 spring run-off season. The remaining moderate priority erosion site will be completed in 2016 and 2017, with repairs to all 2013 Flood damaged erosion sites anticipated to be complete by 2018.

Some of these projects resulted in a loss of fish habitat based on the Department of Fisheries and Oceans Canada (DFO) fisheries act. The City is using a fish compensation program to meet regulatory obligations to compensate for the loss of fish habitat due to the riverbank flood repairs and other related projects.

Please see flood preparation for more information on what The City did to mitigate potential flood impacts in 2014.

About the critical and high priority projects

The priority list is based on our Triple Bottom Line Policy, which accounts for social, environmental and economic costs and benefits for each project.

Below is a list of current and completed projects:

Moderate and low-priority restoration projects

A number of sites are considered low-priority - these sites are being monitored as they may self-heal over time and do not need to be stabilized immediately.

Some of the challenges we face in restoring the riverbanks include balancing a number of elements including environment, fish habitat, flood inundation and infrastructure protection. Other challenges include the locations of the repair work and getting regulatory approvals from the Province on certain projects.

It will likely take until 2018 to repair all of the damage created by the 2013 flood. We will continue working with the Province on longer-term funding strategies.
