Upcoming stormwater system upgrade and pathway detours

After the June 2013 Flood, The City of Calgary inspected the Bow and Elbow Rivers, and Fish, Nose and West Nose Creeks for significant damage to outfalls and riverbanks. The City identified 161 outfalls on the rivers and 53 outfalls on the creeks with damage and have prioritized them for repairs. An existing outfall (B69) in your area suffered damage. This project will repair the damaged outfall and stabilize the bank in the immediate area of the outfall using large stones (called riprap) to protect it from further erosion. We will also remove an existing concrete intake structure from the Bow River just north of the Pumphouse Theatre.

What is an outfall?

Stormwater is rain or snow melt from our roofs, lawns and roadways that enters the storm drains on our streets and travels through an underground pipe system eventually draining into our rivers. The site where the stormwater flows from the pipes and into the river is called an outfall.

Project details

  • Outfall B69 is located along the south side of the Bow River north from the Pumphouse Theatre (Figure 1).
  • Repairs to the outfall involve removal of debris, placing a concrete plug in a buried duct, removing damaged concrete infrastructure, rehabilitating the outfall and reclaiming and protecting the disturbed bank from future erosion.
  • Construction fencing will be in place for the duration of this project.

Construction Impacts

  • Access to the construction site will be from Pumphouse Road SW.
  • Construction vehicles, equipment and a small lay-down area for supplies will occupy the maintained Parks area north of the Pumphouse Theatre (Figure 1) and City of Calgary snow dump area to the east. Both areas will be fenced off for construction access only.
  • Work will be performed from 7 a.m. until 9 p.m. for approximately 3 months.
  • Equipment may be stored in the parking lanes adjacent to the park, and no other impacts to traffic are expected.
  • The temporary staging area and access route will be restored to original condition.
  • There will be a pathway detour around the Pumphouse Theatre (Figure 2).
