What is an Environmental Assessment?
An Environmental Assessment (EA) is the process of determining what environmental impacts, if any, there will be during a project and how to minimize the impacts. The Environmental Assessment process falls under the Ontario Environmental Assessment Act.
The term "environment" includes the natural, social, cultural, built and economic environments.
What is the Focus for the One River EA?
- The One River EA covers the Thames River from Boler Road Bridge to the Forks of the Thames and Harris Park.
- The One River EA will incorporate a number of ongoing plans, partnerships, and studies, including Back to the River, the Pollution Prevention and Control Plan, the Thames River Clear Water Revival, the London Official Plan, and the Thames Valley Corridor Action Plan.
- The One River EA brings these and other projects together to find integrated solutions to their broad social, economic, and natural environment issues.
- The overall goal of the One River EA is to improve the health of the Thames River and its social role in central London.
The Thames River is both our inheritance and our living legacy. It is our collective responsibility to maintain and enhance its shared natural, cultural, recreational and aesthetic resource. The One River EA will consider the area historically influenced by the Springbank Dam, and will provide a plan that coordinates critical infrastructure projects in ways that preserve for future generations this valuable resource, and allow people of all abilities to enjoy and access this designated Canadian Heritage River. This study, in the context of many other ongoing initiatives to improve the Thames River, will endeavor to align important projects in a way that enhances the river overall, maintains the vision of the Back to the River’s “The Ribbon of the Thames” concept plan, and identifies potential impacts to downstream communities and where possible avoid them.
Area of Focus
The One River Environmental Assessment area of focus includes Thames River, contained by Boler Road Bridge to the Forks of the Thames and Harris Park.
Thank you to everyone who participated and provided feedback during the first stage of the One River Environmental Assessment.
The One River EA's first stage of consultation involving the Springbank Dam, whether to have a free flowing river or to reinstate the dam, has concluded. On January 16, 2018 City Council approved the One River Environmental Assessment Update: Phase II Stage I Report, which recommends the decommission of the Springbank Dam.
More opportunities for public engagement will be available during the next stage of the Environmental Assessment.

Stage 1 Summary Report
The One River EA process is being carried out in two stages:
Stage 1: The objective of Stage 1 is the selection of a preferred option for the future of the Springbank Dam which will be an influential factor in the identification and evaluation of the overall river management plan going forward. The option selected will inform the decision-making process on the overall river management plan. A preferred option for the Springbank Dam has been selected based on natural, social/cultural, and technical/economic criteria.
Stage 2: Once the option for the Springbank Dam is selected, alternative strategies for river management, which consist of different types of projects related to infrastructure and river improvements, will be developed and assessed. Stage 2 will be carried out in late winter, spring and summer of 2018 and is anticipated to be concluded early in the fall 2018. This stage will also include stakeholder consultation, including consultation and engagement with First Nations and Metis, government approval agencies, interest groups and the general public.
One River Stage 1 Report Documents:
Based on a comprehensive review of the options for Springbank Dam, the evaluation demonstrates that Option 2 – Free-Flowing River, as the preferred option. Option 2 rated the highest as providing the most benefits and best meeting the objectives of the Problem/Opportunity Statement to “maintain and enhance this shared natural, cultural, recreational and aesthetic resource” and “preserve for future generations this valuable resource and allow people of all abilities to enjoy and access this designated Canadian Heritage River”.
Option 1: Do Nothing – the dam will be kept in its current condition
Option 2: Free-Flowing River – the dam will be decommissioned so it will not provide a water retention function
Option 3: Reinstate the Dam – the dam will be repaired or reconstructed
The criteria for Springbank Dam were developed through consultation with project stakeholders, the general public, and engagement with First Nations. The criteria cover the range of potential changes from what is considered the baseline condition, which is the existing conditions in the river within the study area and the current condition of the dam. The baseline condition was established through the examination of various databases on water quality and the ecological environment, consultation and engagement, and field studies.
The three categories of criteria represent potential impacts on the natural environment, the social/cultural environment, and technical/economic considerations.
The criteria for the natural environment category include water quality, Species at Risk, terrestrial and aquatic habitat, as well as geomorphology (slope and river bottom stability) and groundwater and surface water interactions.
The criteria for the social/cultural category include various forms of recreation, public health and safety, urban revitalization, First Nations interests, cultural heritage, and so forth.
Technical and economic considerations include constructability, approvability (the ability to obtain required permits and approvals), operations and maintenance, relative capital costs, flood hazard, carbon footprint, and compatibility with existing and planned infrastructure projects.
A description of each evaluation category and criteria is provided in Section 4 of the report.
Option 2, free-flowing river, ranked first in its ability to provide a benefit to the natural environment. It has the potential to improve water quality, aquatic and terrestrial habitats, and protect and enhance Species-At-Risk.
Options 2 and 3, free-flowing river and reinstate the dam respectively, have similar ratings. Each of these options have potential to maintain and enhance social and cultural resources in the study area, albeit in different ways.
For the technical and economic factors, Option 1, Do Nothing, rates highest as it is the easiest to implement with the least costs. Option 3 would be the most challenging to implement, in large part due to the anticipated difficulties in receiving permits and approvals.
Score Summary by Category:
Option 1: Do Nothing
Option 2: Free Flowing River
Option 3: Reinstate Dam

The detailed evaluation matrix is provided in Appendix F of the report.
Several methods of consultation were used during Stage 1 to engage the stakeholders in meaningful ways and to receive input. The objectives of the Phase 1 public engagement program were to:
Introduce the One River Master Plan EA to the community
Drive residents to the GetInvolved.london.ca website to learn more about the EA and participation in the One River Public Survey
Engage community members in meaningful conversations about the One River Master Plan EA to gather constructive, solutions-based input
Inform the ultimate selection of an option for the Springbank Dam
To continuously monitor the success of the Public Engagement Program in reaching its audiences, and to adjust the program, as required
An overview of the consultation and engagement activities is provided in Section 7 of the report.
Of those that completed the Public Information Centre survey, 70% of respondents supported an unobstructed river (Option 1 and Option 2) with 24% of respondents in support of reinstating the dam (Option 3). The remaining 6% were in favour of a combination of options or did not provide a response.
The Back to the River “Ribbon of the Thames” award-winning design incorporates a number of elements that support a River vision that has been called bold and exciting. It focuses on bringing people back to the River to enjoy a significant cultural and heritage resource and engage in activities that reflect the river’s beauty and cultural significance. Coordination with the Ribbon of the Thames Civitas/Stantec team has begun on how the design elements of Back to the River can be integrated into the EA evaluation and be adapted to potentially changing water levels. The design elements of the Ribbon of the Thames can be integrated into the range of water levels represented by the Springbank Dam options.

Subject to council approval of this report, the One River EA project will move ahead as three separate initiatives. The “Forks of the Thames” initiative will consider the council endorsed “Ribbon of the Thames” design submission selected as part of the Back to the River international design competition. The “River Enhancements” initiative will consider river enhancement and improvements, building on public comments suggested during the first stage of the One River EA. This initiative will consider projects such as canoe and kayak launch locations, improvements to existing public amenity/look-out spaces, environmental stewardship projects, and erosion improvements. The final initiative the “Springbank Dam Decommissioning” will consider the most environmentally appropriate way to decommission the Springbank Dam.
