After the flooding of 2013, the Town of Canmore 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 in May 2014. Our focus is now on long-term mitigation. While significant work has been done on many creeks, Cougar Creek the most dramatic, the work completed to date was meant to protect against an event of similar size. There have been larger events in the past and the goal of the program is to install infrastructure that protects the community against these potential larger events that may occur in the future.

Debris Flood Retention Structure
- The pdf Environmental Impact Assessment Report (130.63 MB) was submitted to Alberta Environment and Parks (AEP) in July 2016 and is currently being reviewed.
- AEP has sent the Town Supplemental Information Requests (SIR) in December 2016. The Town has submitted to AEP the pdf SIR 1 Response Package (64.12 MB) in June 2017. The Town has also submitted pdf Post-Submission Clarifications (338 KB) in July 2017.
- AEP has sent the Town Supplemental Information Requests (SIR) 2 in October 2017. The Town has submitted to AEP the pdf SIR 2 Response Package (14.38 MB) in December 2017. Moreover, the Town has also submitted an pdf EIA Project Update (7.48 MB) in December 2017 which describes design changes made to the Structure since the submission of the EIA.
- AEP has sent the Town Supplemental Information Requests (SIR) 3 in March 2018. The Town has submitted to AEP the pdf SIR 3 Response Package (303 KB) in March 2018.
- The pdf EIA (226 KB) has been deemed complete by AEP on March 23, 2018.
- The Town has applied to the NRCB and AEP for the construction of the Structure on April 11, 2018 and the NRCB had provided the following pdf Notice of Application (119 KB) .
- The Dam Safety submission was submitted to AEP in August 2016 and is being reviewed.
Peaks of Grassi (X,Y,Z) Creeks and Echo Canyon Creek
- The Town received funding to be able to complete the hazard and risk assessment of X, Y, Z creeks (above the Peaks of Grassi) and Echo Creek Canyon (near Alpine Club of Canada).
- A consultant has been selected and the project was awarded on April 2nd, 2018.
- The consultant will be undertaking field work during the week of May 7th, 2018 and during the week of June 4th, 2018. In May, you can expect to see a few people walk the fan areas of the creeks, as well as further upstream in the channel. Visual inspections, measurements and dendrochronology will be undertaken at that time. In June, a small test trenching program will be undertaken in the Peaks of Grassi area. A small rubber tracked excavator will be used to dig down 2-3m in several areas to expose and record the different layers of soils, rock and ashes deposited over hundreds of years. The test trenching helps recreate past events to better inform the hazard assessment. The trenches will be backfilled with native material and re-seeded with native grass mix. The test trench locations have been chosen to minimize the impact on vegetation.
- Council presentation of the results, as well as a public presentation with Q&A session, are currently planned for the fall of 2018. The project should be completed in early 2019.
