This document summarizes a study on stormwater impacts to McVicar Creek. The study aimed to: identify impacts; characterize them through a stream assessment; identify 3 representative sites; pursue further research; and develop remediation recommendations. The initial assessment identified 3 sites - Court Street, Castlegreen, and County Fair - for further study. Additional data collection and stakeholder workshops were held. The workshops developed stormwater management objectives and site-specific recommendations. For Court Street, increased enforcement and education were recommended. For Castlegreen, investigating infrastructure and partnering with local groups. For County Fair, educating landowners and considering end-of-pipe solutions were recommended. The final recommendations emphasized objectives and further stakeholder

Dwindling availability of water, combined with increases and competition in demand, climate change impacts, trends toward true cost water pricing, among other “drivers,” necessitates that urban water planning incorporate consideration of strategies for use, conservation, and reuse of treated wastewater and stormwater. Three innovative initiatives will be discussed as illustrations of “win-win” approaches that achieve effective water management (urban water security/sustainability) while facilitating economic development.

It is increasingly being recognised internationally that integrated catchment management (ICM) is a useful organising framework for tackling the ongoing challenge of balancing sustainable use and development of our natural resource, against achieving environmental goals. The basic principles of ICM (Williams, 2012) are to:
• Take a holistic and integrated approach to the management of land, biodiversity, water and community resources at the water catchment scale;
• Involve communities in planning and managing their landscapes; and
• Find a balance between resource use and resource conservation
ICM is now well established in Australia, New Zealand, and the United States. In Europe the ICM approach has been proposed as being required to achieve effective water and catchment management, and is the approach being promoted by DEFRA for the UK, where it is called the “Catchment Based Approach” (CaBA). The principles and methodologies behind ICM sit well within the context of the Water Framework Directive with its aims and objectives for good water quality, sustainable development and public participation in water resource management. In Ireland it is proposed that the ICM approach will underlie the work and philosophy in developing and implementing future River Basin Management Plans.

3. Purpose of the Study
The main purpose of the Stormwater
Impacts Assessment Study was;
• To Identify stormwater related
impacts on McVicar Creek
• To characterize these impacts
through a Unified Stream Assessment
• To identify the 3 most representative
stormwater subwatersheds along the
creek
• To pursue further research on these 3
sites and;
• To develop remediation
recommendations for the 3 identified
sites and McVicar Creek as a whole
4. How to achieve the purpose of the study
An initial assessment was completed
along the entirety of the creek, from
that assessment, the 3 sites were
identified. Further research was
completed to;
• Develop a feasibility criteria of site-
specific stormwater remediation
options for each site
• Implement a decision-support
criterion to identify the most
effective stormwater remedial
options based on; Low Impact
Development (LID), education,
policy/regulation and maintenance
• Produce a remediation option plan
using expert feedback along with
data collection
5. Initial Unified Stream Assessment
Results
The initial Unified Stream Assessment (USA) confirmed the
suspected theory of stormwater pollution being contributed to
McVicar Creek, and proved the need for continued research.
• Stormwater outfalls are in fact contributing to degraded water
quality such as elevated levels of nutrients and metals
• Effects of pollution found to degrade infrastructure integrity,
cause declined aesthetics and cause impairments to aquatic
habitats
• Future research is recommended to assess localized and
detailed stormwater impacts along the creek (RAP, 2010)
6. Detailed Unified Subwatershed and Site
Reconnaissance study
USSR Site Assessment Results
• The results of the USA determined the 3 most representative
sites along the creek for future study; Court Street, Castlegreen
and County Fair
• The USSR study assessed the impacts of stormwater from a
subwatershed perspective based on behaviours within the
terrestrial environment
• The results and recommendations drawn from USSR were used
to complete the final recommendations for remediation options
along the creek.

10. Initial USSR Study Resulting
Recommendations
Recommendations:
• Court Street:
• A focus on community education in properly connected rainbarrels,
effects of auto fluids from home vehicle repair shops on the
aquatic environment, and alternative snow removal
• Castlegreen:
• Focus on community education in the effects of gardening
chemicals and pet waste on aquatic systems. Also landscaping of
the 100% impervious parking lots
• County Fair:
• Possible end-of-pipe LID design and policy enforcement and
maintenance on the back mall parking lot
11. Development of Remediation Option Plan
Research was aimed at finalizing a remediation option plan
based on the initial recommendations produced from USSR
• Continued Quantitative data collection on all three sites:
• Water quality testing based on seasonal collection to monitor
water quality discharge into the Creek
• Development of a case study plan based on a possible end-of-
pipe LID on County Fair
• Further water quality testing done upstream and downstream of
outfall, soil nutrient, organic and composition testing and infiltration
rate testing
• This additional testing was to determine if County Fair was a
suitable LID site and aide in final remediation recommendations.
12. Why County Fair as an LID Case Study
Reasons why the County Fair site was selected as a case
study through USSR assessment
• Ownership of the land
• Overall end cost
• Feasibility based on Thunder Bay’s current stormwater
management practices
• Location for optimal community education and outreach and;
• Localized stormwater inputs
13.
14. Results of the Quantitative data
• Court street:
• Continued, concerning elevated
levels of ammonia, nitrate and
chloride
• Castlgreen:
• Continued, concerning elevated
levels of ammonia, nitrate, nitrite
and phosphate
15. Quantitative Results of County Fair
(LID Case Study)
• Concerning water quality
parameters (all locations sampled):
ammonia, nitrate and phosphate
• Soil: Soil testing results showed
relatively suitable soil conditions
(with some engineering alterations)
for a vegetated infiltration LID at the
current wetland, not downstream.
• Infiltration: Infiltration rates at the
current wetland showed suitable
levels for infiltration LID, again, not
downstream
16. Quantitative data not the final say
The quantitative data used throughout this project does not
have the final say in the recommendations, the qualitative
data does….
• The quantitative data used in this research project included the
involvement of a multi-stakeholder group throughout the
process.
• This multi-stakeholder group included representatives from; The
City of Thunder Bay, EcoSuperior, Lakehead University,
Earthwise®,
Ontario Ministry of Natural Resources, Ontario
Ministry of the Environment, The Northshore Steelhead
Association and the Lakehead Region Conservation Authority.
17. Stakeholder Involvement
There were 3 main stages of Stakeholder involvement in
decision-making.
• Stage 1: Introduction

information.
• Stage 2: Site Visit
• This included a group visit to all three sites with information
provided.
• Stage 3: Workshop
• This included a Multi-Stakeholder Decision Making (MSDM)
workshop structured to produce final remediation
recommendations for this project.

20. Final Remediation Recommendations for
McVicar Creek Resulting from this Project
1) First and foremost that the defined objectives for Thunder Bay
stormwater management be considered in all further
stromwater management
2) Before further stormwater remediation plans are pursued on
McVicar Creek that the final recommendations proposed by
Stakeholders are completed; An education and outreach plan
on McVicar Creek watershed hotspots and in the watershed as
a whole
3) That the process used in this research project be referenced to
determine further stormwater remediation options within
Thunder Bay
4) That the baseline data collected in this project be used for any
further LID proposal on the County Fair site
