Project History

As of June 2019:

Debris Flood Retention Structure

  1. The  pdf Environmental Impact Assessment Report (130.63 MB)  was submitted to Alberta Environment and Parks (AEP) in July 2016.
  2. The Dam Safety submission was submitted to AEP in August 2016. 
  3. AEP 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.
  4. AEP 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.
  5. AEP sent the Town Supplemental Information Requests (SIR) 3 in March 2018.  The Town submitted to AEP the  pdf SIR 3 Response Package (303 KB)  in March 2018.
  6. The  pdf EIA (226 KB)  has been deemed complete by AEP on March 23, 2018.
  7. The Town 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) .
  8. The NRCB issued approval for the Cougar Creek debris flood retention structure on November 15, 2018.  The following  pdf news release (133 KB)  and  pdf background information (129 KB)  has been issued by NRCB.  The complete  pdf Board decision (2.77 MB)  is a 90 page document outlining the decision process and the conditions of approval.
  9. Request for Proposal was issued in 2018 to find a well-established Canadian firm specialized in dam construction in mountainous terrain in western Canada. They have completed the first phase of work, including high-level cost estimates. To improve constructability and reduce costs and construction time (by 6-12 months), CPL recommended the Town consider alternative approaches to constructing several project elements. The alternative approaches retain the same risk reduction to residents and infrastructure downstream, do not change the structure location, and are designed to the same high standards, such as the Canadian Dam Association Guidelines and Alberta’s Dam and Canal Safety Directive.
  10. A written project update was submitted in early 2019 to AEP, the NRCB, and Treaty 7 First Nations to provide the information they require to complete any additional review needed. The approval process is still unclear, as the NRCB requested additional information that will be submitted in the summer of 2019.
  11. Administration is working on the Water Act application package. It will be submitted later in 2019. Time frames for permits remain uncertain.
  12. Administration is working with AEP to ensure that the required land disposition is in place by the time of construction (a disposition is a land use contract that gives specific rights to a land or resource use).
  13. Construction start date is uncertain, likely no earlier than spring of 2020, but the construction duration expected to be 18-24 months.
  14. The NRCB issued approval for the revised Cougar Creek debris flood retention structure on October 23, 2019. The following pdf news release (32 KB) and pdf background information (43 KB) have been issued by the NRCB. The complete board decision can be pdf found here (3.05 MB)
  15. Through a Request for Pre-qualification issued in late 2019, the town has shortlisted the following five companies: Kiewit, Aecon, Flatiron, Barnard, Speers Construction/VVI Construction. Only these short-listed companies were able to bid on the project. Bids were received in May of 2020. The lowest compliant bidder is Flatiron Constructors Canada Limited. Flatiron was awarded the project shortly after.
  16. The construction of the project started in late June 2020.

Short-Term Mitigation

Short term mitigation works were completed before the 2014 spring run-off. The mitigation work included widening and deepening the creek bed and installation of articulated concrete mats for erosion protection in the main channel of Cougar Creek, from the Wildland Park Boundary to the Trans-Canada Highway. Additionally, a 6m tall and 40m wide debris net was installed at the apex of the fan to capture up to 15,000 m3 of sediment. The debris net is a temporary protection structure until the debris flood retention structure is constructed.
