Eau Claire – flood resilience project update

About the project

After the June 2013 Flood, The City of Calgary Water Services identified and prioritized outfalls prone to backflow during high river flows. This project involves installing two back-flood prevention gates in a new manhole upstream of outfall B44, one of the identified outfalls. The back-flood prevention gates will assist in preventing flooding of areas upstream of the outfall. The new manhole is located in a landscaped area adjacent to the Bow River Pathway at the north end of 2 street S.W.

Construction is ongoing and is expected to wrap up this spring.


  • The manhole has been installed and all excavation work has been completed.
  • The gates have arrived and are being installed. The contractor is finishing up and should be off-site by the end of March. The fencing will be left in place but there will be no active construction on the site untilthe weather warms up, when final restoration of the site will take place.
  • Paving of the pathway connector and landscaping will be completed in Spring 2016 (weather dependent).

Impact to citizens

  • The pathway connector between 2 street S.W. and the Bow River Pathway will remain closed and pathway users will continue to be detoured to the west side of the River Run Condos (north of Eau Claire market).
  • Site access for construction vehicles will continue to be from 2 street S.W.
  • The construction fence will remain in place until landscaping is complete and the pathway can be reopened (Spring 2016).
