In collaboration with Enbridge and the Town of Milton, Conservation Halton undertook a priority environmental project to decommission the existing Drumquin Park weir on East Sixteen Mile Creek and restore the natural channel function and habitat. Sixteen Mile Creek provides aquatic habitat to many species including the Silver Shiner, a species classified as at risk in Canada and threatened provincially. Removal of the Drumquin weir provides the opportunity to restore connectivity to downstream occupied Silver Shiner habitat and rehabilitate degraded Silver Shiner habitat – actions that address the various recovery objectives for this threatened species.
River Engineering and Technical Services GIS Support
AEP’s River Engineering and Technical Services Section identified various areas within their organization where they needed support to migrate both spatial and non-spatial data into consistent data models, as well as evaluate incoming spatial data deliverables provided by their consultants. The purpose of such work is to facilitate greater use of enterprise database systems and web mapping applications internal to AEP.
Spill Response and Remediation Program Management
Murphy Oil Corporation discovered a condensate release from one of its pipelines at three separate surface locations in April 2015. Our client needed to delineate and contain the spill. Monitoring of wildlife, surface water, groundwater, and atmosphere quality was required to assess for impacts from the release. Once containment was put in place, Murphy needed to remediate and manage risks associated with the spill.
City of Calgary 12 St. S.E. Bridge Replacement
The City of Calgary recently embarked on a project to replace the 109-year-old 12 Street S.E. Bridge over the Bow River, the main access point between the Calgary Zoo and locations to the south. The bridge was in poor condition and deteriorating beyond a safe, useable condition.
AltaLink Oldman River Bank Protection
The foundations of four AltaLink transmission structures were threatened due to significant bank erosion along a 900m reach of the Oldman River, Alberta. Further bank erosion could impact the reliability of the line or require the relocation of the structures to another location.

We routinely lead characterization of stream morphology to:
- Assess fluvial erosion hazards
- Develop alternatives for erosion control in environmental assessments
- Develop management strategies as part of land use planning (subwatershed, secondary, tertiary plans and site plans)
- Assist in culvert/bridge design
- Define erosion thresholds to inform stormwater management
