Cougar Creek Debris Flood Retention Structure
September 19, 2016
NRCB Application No. 1601
In July 2016 the Town of Canmore (Town) submitted an Environmental Impact Assessment (EIA) to Alberta Environment and Parks (AE&P) for a proposed debris flood retention structure and access road. The project location (14-34-024-10 W5M) is at the site of an existing debris net on Cougar Creek, approximately 2 km northwest of the Trans-Canada Highway.
On August 19, 2016, the Town filed an application with the NRCB (the Board). The proposed project consists of the structure on Cougar Creek that will be 29.85 m high and will span a bedrock confined channel. The structure will be a rock and earth filled embankment with a reinforced concrete central sealing wall, and an open outflow with a throttle and debris rake. During normal weather conditions water and sediment will flow unimpeded through the structure. The project description is set out in more detail in the EIA, which forms part of the Town’s application (NRCB Application #1601) to the Board.
On September 6, 2016, the NRCB and AE&P issued a Joint Notice of Filing.
