McHugh Bluff slope remediation project
Project update – February 2025
Work on stabilizing the slope at McHugh Bluff started in late October 2024. Crews have finished part of the work on the upper slope and have now started stabilizing the lower slope. Construction is expected to finish by the summer 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 include:
- 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 will remain closed until the completion of all remediation efforts. Please refer to the map below for detailed information about closures and detours.
Frequently Asked Questions
Is there currently any danger to the adjacent homes?
No, The City of Calgary and our contracted partners continue to monitor the slope. Repair work will begin in October 2024.
Why is the pathway closed?
Following the slope failure, trees and other material fell onto the pathway. Out of an abundance of caution and to protect the stability of the slope until remediation work is finished, the pathway has been closed. Please follow the signs onsite and use the detours provided.
