Flood Mitigation Study for New Hamburg

Flood Mitigation Study for New Hamburg

The Town of New Hamburg is located along the Nith River and is one of 27 municipal flood damage centres in the Grand River Conservation Authority’s (GRCA’s) jurisdiction. The Town was established and developed in the Nith River floodplain and is subject to routine nuisance flooding; in addition to significant flooding events in 1975, 2008, and most recently in February 2018 and January 2020. Matrix was retained to estimate average annual flood damage costs associated with existing flooding, develop and evaluate potential mitigation strategies, and provide support for two Public Information Centres (PICs).

West Eau Claire Park Public Realm Plan

West Eau Claire Park Public Realm Plan

West Eau Claire Park is a popular area along the Bow River, just north and west of downtown and near the iconic Peace Bridge. The City of Calgary wished to connect the community with the Bow River and also provide important flood protection for downtown Calgary. The park was redeveloped through widening and raising the existing pathway, protecting and enhancing the river bank, and grading and landscaping the south overbank area to protect against a 1:200-year flood event with 0.5 m of freeboard.

Frenchman River Reconnection Project for Trout Unlimited Canada

Frenchman River Reconnection Project for Trout Unlimited Canada

As part of their Reconnecting Canada initiative, Trout Unlimited Canada (TUC) identified an opportunity to address an obstruction to fish passage in the Cypress Hills Uplands region of Southwestern Saskatchewan. The Frenchman river reconnection project aimed to solve the issue of lost connectivity that had been created by scour at the outlets of several hanging culverts within two tributaries of the Frenchman River: Caton Creek and Davis Creek. The purpose of the project was to increase available habitat for threatened Plains Sucker (formerly known as Mountain Sucker) populations, improving their ability to adapt to the growing pressures of climate change and habitat loss. Changes to water flow and fish passage are described as threats to Plains Sucker populations as is genetic fragmentation created by improperly designed or failed infrastructure. These fish play an important role in the ecosystems that they inhabit.

Drumquin Park Weir Removal and Channel Enhancements

Drumquin Park Weir Removal and Channel Enhancements

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.

Gas-Fired Power Plant Approval

Gas-Fired Power Plant Approval

Signalta Resources required approvals from both Alberta Environment and Parks (AEP) and the Alberta Utilities Commission in order to construct a new natural gas-fired power co-generation facility providing electricity, heat and carbon dioxide (CO2) to a neighbouring greenhouse east of Coaldale, Alberta.

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
