McHugh Bluff slope remediation project

Project update – August 2025

McHugh Bluff slope remediation is now completed. The pathway between 5A Street and 6 Street N.W. has been reopened since Friday, August 15, 2025.

Project overview

In August 2021 following heavy rainfall, a section of the McHugh Bluff slope behind 3 Avenue N.W. become unstable. The City of Calgary initiated monitoring and engaged a consultant to conduct a geotechnical assessment. Based on their findings, a remediation plan was developed to address the slope stability.

Key components of the remediation included:

  • Installation of soil nails with shotcrete
  • Placement of sheet drains
  • Installation of horizontal slope drains
  • Application of high-strength wire mesh, steel plates, and geosynthetics
  • Reconstruction of the existing gabion basket retaining wall adjacent to the pathway

Short-term measures

In spring 2022, short-term measures were implemented, including the placement of coir matting to secure erosion gullies and delay further surface erosion.

Pathway status

The pathway is now open for public use.

It remained closed during the slope remediation from October 2024 to August 2025.
