Slope stability management policy and framework

Calgary is built around two river valleys and has several hillsides that are considered unstable. The City of Calgary monitors and responds to all hillside instabilities on City property. Addressing natural slope failures in a timely manner is key to mitigating potential property damage and safeguarding the public.

Hillsides that are unstable are monitored on an ongoing basis. If a natural slope is at risk of failure and will impact City infrastructure (pathways, walkways, roads, structures, etc.) it will be assessed for repair. After public safety is secured, a geotechnical engineering consultant is hired by The City to investigate the cause of the failure and to recommend solutions for remediation.

If the slope stability concern poses an immediate danger to people or property call 911.
