Downtown Flood Barrier & Eau Claire Promenade

Project update - Fall 2021

Community Impacts & Schedule

Fall look ahead:

  • October & November:
    • Sheet piling is expected between Reconciliation Bridge and Centre Street until late October. Sheet Piling will move west as sections are completed. Piling is expected into December.
    • Drilled piles installed near the Eau Claire Lagoon for the observation deck.
    • Construction of the Centre Street Ramp abutments and installation of concrete piles.
    • Instream work under the Centre Street Bridge for the new retaining walls and pathway underpass.
    • Foundations for the stoplog flood mitigation systems (removable flood walls) at the pathway connection openings.

Sheet piling schedule:

  • Reconciliation Bridge to Centre Street: September – October
  • Centre Street to 2 Street S.W.: November
  • 2 Street S.W. to Jaipur Bridge: late November - December

Expected timeline: The above schedule is subject to change based on weather or other unforeseen circumstances.

The Downtown Flood Barrier and Eau Claire Promenade construction contract was awarded to Graham Construction, and the construction is well underway.

In early August, a detour was installed on Riverfront Avenue to support the closure of the Bow River Pathway and RiverWalk. With the detour and fencing are in place, site prep, demolition, and groundworks was completed to prepare for the installation of the flood barrier sheet pile. As part of the site preparation, we worked to salvage and transplant plants from RiverWalk.

With the removal of the Centre Street Bridge Ramps and the instream work started, installation of the sheet piles has started. These piles are vital to creating the flood barrier that will help protect downtown, Chinatown, East Village and Eau Claire from future flood events. The work is underway on the east end of the project at Reconciliation Bridge and will move west towards Centre Street. It will connect with the flood mitigation measures in Eau Claire Plaza and the new Jaipur Bridge. Sheet piling is expected to be ongoing throughout the fall.

Crews are also drilling the piles required for the Centre Street Ramps and the observation deck that overlooks the Eau Claire Lagoon, near the new Jaipur Bridge. This work will tie into the Eau Claire Promenade and connect the projects in the area.

We are constantly monitoring and adjusting the piling to ensure we are within mandated ranges for noise and vibration.

Construction in Eau Claire

To ensure Calgarians can safely visit and enjoy the area, you will see construction fences, pathway detours, and construction activity in the Eau Claire, Bow River Pathway, and RiverWalk area. Please follow the signs.

For up-to-date information and more detail, please visit our construction and detours webpage. Our website will be updated throughout construction to keep you informed about getting around and what to expect in Eau Claire.

About the projects

Downtown Flood Barrier

Protecting Calgarians from floods is a top priority for our city, and we're doing so while enhancing the Eau Claire area at the same time. We're implementing flood mitigation measures from Calgary's Flood Resilience Plan approved by Council in 2017.  These include flood barriers and stormwater improvements to ensure Calgary is protected against a 2013-level flood on the Bow and Elbow Rivers. The Downtown Flood Barrier will extend from The Peace Bridge to Reconciliation Bridge and lower the risks of flooding in the downtown, Chinatown, East Village and Eau Claire communities. 

Eau Claire Promenade

The Eau Claire Promenade extends from The Peace Bridge eastwards to the Reconciliation Bridge. Our goal is to extend the work we did at West Eau Claire Park to create a safe, efficient and beautiful riverfront promenade and cycle network that integrates flood protection into a space that connects Calgary’s downtown with the Bow River.

Our goals for the Promenade focus on:

A space for the City and Community

  • Accommodate all users for all of Calgary
  • Connect people to the Bow River
  • Build a vibrant centre city riverfront
  • Design a diversity of social spaces for mental well-being
  • Promoting active, healthy lifestyles Incorporate strategies for year-round healthy, active lifestyles – a better space for walking, jogging, biking, etc.
  • Provide a continuous, safe and accessible riverfront promenade
  • Designate efficient pathways for safe alternate modes of transportation like scooters

Environmental Responsibility

  • Preserve the natural environment by protecting most of the existing trees and plants along the river
  • Achieve multiple cost benefits through durable and beautiful design solutions

Flood Protection and Resilience

  • Integrate flood protection into the public realm improvements
  • Increase resilience for Eau Claire, the Downtown Core and future infrastructure projects

Both the Downtown Flood Barrier and Eau Claire Promenade projects are coordinated with the overarching Eau Claire Area Improvements.
