Moving Forward... After the flooding last summer, the Town created a Mountain Creek Hazard Mitigation Program. One element of this program was to get short-term mitigation in place in time for 2014 spring run-off. This was completed in most of Canmore’s mountain creeks by May 2014. Another element of the program is to better understand the hazards and risks associated with debris floods and debris flows. The key results of the Mountain Creek Hazard Mitigation Program are: • Stakeholder Alignment
– Ongoing community communications and partnering with key stakeholders • Hazard Assessed
– Forensic study and hazard mapping and return period and magnitude analysis • Risks
Understood – Community wide safety risk analysis and infrastructure and property inventory • Successful Active
Mitigation – Funding, permitting, approvals for short and long term infrastructure
• Successful
Passive Mitigation – Emergency planning and preparedness and updating municipal and provincial policy Our focus now is turning to long-term mitigation. While significant work has been done on many creeks, Cougar Creek being the most dramatic, the work completed to date was meant to protect against an event of similar size of the 2013 event. So much good work was done that it might seem like the mitigation work is complete. However, we’ve learned in the last year that even larger events have occurred in the past and could occur again in the future, so we need to install infrastructure to protect our community against the risks associated with a larger event. Ultimately, our end goal is an acceptable level of protection against all hazards. Right now, our focus is on mountain creeks. We do have other risks in our community including wildfire, river flood, proximity to dangerous goods routes, and severe weather. Town staff are working to be prepared for and mitigate against all known community risks. This issue of the newsletter explains how we will work with the community to create long term mitigation to protect against future debris floods and debris flows on our steep mountain creeks.
