Bowness Flood Barrier

What's happening

Bowmont Park

The proposed Bowness flood barrier is a foundational piece of The City of Calgary's Flood Mitigation and Resiliency Plan. In conjunction with upstream storage, provided by construction of a new reservoir, and modified operations of TransAlta's Ghost reservoir, it will help us better manage flood water and avoid the type of damage we saw in 2013.

Work on the proposed Bowness flood barrier is in the preliminary design stage, which takes place from fall 2018 to fall 2019. It consists of gathering feedback from community members, conducting site surveys, and completing engineering studies and analyses.

Upcoming studies and analyses

Beginning in fall 2018 and continuing into 2019, the following studies and analyses will be undertaken:

  • Hydrogeological (groundwater studies) - currently underway
    • The City has begun installing monitoring wells on public and private land to understand the ground conditions and potential impact from groundwater flooding to the community. Additional monitoring wells will be added in spring 2019. The monitoring wells will be in place until summer 2020. See map of monitoring well locations.
  • Geotechnical investigations - currently underway
  • Flood modelling
  • Stormwater management
  • Landscape architecture and design
  • Biophysical impact assessment
  • Revised cost estimates and Triple Bottom Line

Getting input from the Bowness community

Engagement with the broader Bowness community began in early 2018. Engagement with riverfront property residents began in fall 2018 and will be an important piece of the preliminary design process.

Much of the riverfront property is privately owned in Bowness. Throughout the preliminary design phase, the project team will be working with individual property owners to gather their input, discuss their concerns and develop ideas to be potentially incorporated into the finalized preliminary design options.

The project team has begun one-on-one site meetings with riverfront property owners to better understand the unique characteristics of their property and discuss ideas on how to best integrate the barrier into the existing landscape, while protecting the community. From here, the design team will use a combination of aerial photos, resident input, along with information collected through technical studies to develop design options.

Design options are tentatively scheduled to be ready in spring 2019 for review and will be presented to riverfront property residents at that time.

Public Engagement

Site meetings with riverfront property owners
Fall 2018 - Spring 2019

The project team is meeting individually with riverfront property owners to discuss the project and collect information about each property to be used in developing a preliminary design for the proposed Bowness flood barrier. The project team will bring copies of the following questionnaire to the meeting. Residents do not need to print/fill out their own copy.

If you are a riverfront resident and would like to sign up for a one-on-one, please contact Lauren Minuk at 403-268-8044 or email
