The June 2013 flooding in the Bow River Basin caused the West Terrace Pond south of the Water Treatment Plant to be overtopped, as well as caused significant erosion on the banks of Jumpingpound Creek. Since 2013, further erosion along the banks of the creek has also been noticed.
The overtopping and sedimentation of the West Terrace Pond in 2013 resulted in the pond no longer being able to operate as originally intended as a stormwater management facility. Flood hazard mapping was completed since 2013, and has determined that a pond in this location must be able to withstand periodic flooding. In order to accommodate future flooding, the pond will be expanded to serve a stormwater management function. Because of the change in type of pond, the outfall from the water treatment plant is also needed to be modified. The pedestrian bridge was also damaged during the 2013 flood and will also be replaced and include better access for maintenance and emergency vehicles to the area when necessary.
Work is also required along Jumpingpound Creek due to increased erosion. It was determined that measures should be taken to restore the bank and to prevent further erosion in the area. The construction will also create a bank that supports vegetation growth and creates fish habitat. A segment of the existing multi-use trail also runs along the creek’s eroded bank. To prevent further erosion of the bank as well as ensure public safety, the trail is to be relocated further west.
