The Environmental Management Role
Our team of environmental managers, plus avian, terrestrial and aquatic biologists and monitors, implemented a full ecosystem approach, managing all environmental aspects of the project. This included: transfer of snakes and more than 200,000 plants from the impact footprint to protected habitat; baseline and construction monitoring under SAR permitting obligations; sustainability planning; site restoration management; and daily snake tracking with radio telemetry. We were also the environmental design lead, responsible for environmental mitigation, including ecopassage habitat features, 60+ hectares of tallgrass prairie landscape restoration and four hectares of pond, creek, wetland and floodplain fish habitat restoration – all of it intricately interwoven within the Parkway corridor and adjacent natural areas.
As part of the SAR management program, our team provided mandatory induction training for more than 8,000 staff and subcontractors.
As lead Environmental Consultant, our team of environmental experts used industry-leading methods and innovations to minimize the Parkway’s impact on both the environment and the local community without impeding the systematic and efficient construction delivery of the project. This same innovation and environmental guidance has continued seamlessly, from implementation into the operations maintenance & rehabilitation phases of the project.

Innovation by Design
Today, the Parkway features two ecopassages, the largest of which measures about 1.4 hectares and stretches over two highways. They allow snakes and other wildlife to cross between two natural habitat areas that had been separated by road development since the 1920s. Although such sizable ecopassages are typically created for larger mammals – like elk, caribou, bears or deer – the structure was utilized in this case, and a first for snakes, because of the global rarity of the local Eastern Foxsnake. A functional objective was to improve population dynamics, and our tracking data has confirmed the snakes immediately started using the passages.
Additional amenities of the Parkway include more than 121 hectares of green space and 16 kilometers of recreational multi-use trails, as well as a culvert that allows snakes safe passage under the trail. Our extensive ecological landscape restoration and management measures were also applied throughout the corridor, as well as adjacent lands, to promote rare Tallgrass Prairie habitat and protect additional rare plant and animal species.
Highlights of our work include the use of innovative techniques to increase habitat diversity – among them: the demolition of a housing development to establish new Tallgrass Prairie and using the house foundations to create overwintering areas for prairie snakes and other animal species; and the integration of stormwater pond outfalls into creek restoration designs to extend flow duration and habitat opportunities.
Community and Stakeholder Engagement
Key to reaching the final solutions was the outreach and stewardship our team provided to local and Indigenous communities, as well as regulatory subject matter experts. That engagement provided us the opportunity to educate the public and other stakeholders on the importance of the rare species involved and raise awareness about the full extent of actions taken to protect them while building the parkway.
It also enabled our team to receive valuable feedback, as well as traditional knowledge, so our designs and management actions could be optimized to best benefit the local ecosystems.
Our Legacy
Our involvement with this project – and collaboration with our client, Windsor Essex Mobility Group, as well as the owner – is for the long- term. We started in 2010, providing design engineering and construction support services during the five-year construction phase. Following final completion, we secured a contract to provide environmental management continuity for the first 15 years of a 30-year operations contract. In 2020, we completed a decade of permit-based wildlife monitoring, which will not only be used to close out the Ministry of Transportation’s Endangered Species Act permits, but also to produce scientific papers for the academic community.
It’s a Parkway in a prairie – and a rare example where environmental regulatory obligations and the wishes of an interested local and Indigenous community intersected with the necessary project-based funding to provide a wide range of comprehensive solutions. It resulted in a design that not only maximized ecological function but also met recreational and aesthetic objectives, while supporting Canada’s need for transportation improvements in a key international trade corridor.
Note: This work was initiated under Wood’s E&I, who joined WSP in an acquisition completed in 2022.
