Town of Stouffville Stormwater Management Master Plan

The Town of Stouffville is developing a Stormwater Management Master Plan to establish a comprehensive strategy to manage stormwater.

Stormwater is the rain and melted snow that runs off streets and properties, into creeks and streams, and eventually into rivers and the Great Lakes.

The Town is developing a Stormwater Management Master Plan (“SWM Master Plan”) to understand the stormwater system needs through to the year 2051, and recommend solutions where needed. It will consider opportunities to improve water quality and reduce urban flooding and recommend improvements to the reliability, efficiency, and capability of the Town’s stormwater system.

This project will:

1. Help us understand the current performance of the stormwater network in the Town. It will also consider future stormwater needs as the community grows.

2. Identify and rank different stormwater management solutions over the short-term and long-term. It will recommend solutions to improve existing conditions and to use in new developments.

3. Help the Town schedule and budget for additional projects between now and 2051 and provide cost estimates and suggest funding opportunities for these projects

The survey should take approximately 10 minutes to complete. The information boards from the Public Information Centre (PIC) held May 28, 2026, are available online by clicking here:

Unsure

Question Title

* 3. If you answered No, or Unsure, what would you change or add?

Question Title

* 4. Have you experienced stormwater management problems (e.g., flooding, standing water, erosion, or drainage issues) near your home, workplace, or anywhere else in Stouffville?

Question Title

* 5. If you answer yes, please provide more information: what the problem is, where it occurred and any other details you feel are important.

Project and Study Process

Question Title

* 6. How much does stormwater affect your day-to-day life

Not at all

Occasionally

Regularly

Significantly

Question Title

* 7. Are there locations in Stouffville you believe are particularly at risk? (Even if you haven’t personally experienced problems there yourself).

Question Title

* 8. What types of stormwater measures would you like to see used in your community? Check all that apply. Select the options that feel most relevant to your community.

End-of-Pipe Measures: Measures that discharge treated water to receiving watercourses (i.e., wet pond, dry stormwater pond, constructed wetlands, etc.)

Conveyance Infrastructure and Control Measures: Measures that transport runoff, and may also provide treatment (i.e., bioswale, drainage ditch, pipe, etc.)

Source Control Measures: Measures that capture runoff at the source (i.e., permeable pavements, green roofs, rainwater harvesting, etc.)

Pollution Prevention Measures: Municipal activities or programs that reduce pollution of runoff (i.e., road salt management, well protection, etc.)

Operations and Maintenance Measures: Municipal activities or programs that improve stormwater management (i.e., street sweeping, leaf pick-up removal, and sediment removal, etc.)

All of the above

None of the above

Question Title

* 9. When considering Stormwater Management solutions, what factors are most important to you? Please rank the following factors from most to least important, with 1 being most important and 5 being least important.

Question Title

* 10. Please specify what “Other” refers to if you selected it as your highest ranking.

Question Title

* 11. Please specify what “Other” refers to if you selected it as your highest ranking.

Question Title

* 12. Would you recommend the Town change any of its current stormwater practices? Why do you think they should be changed?

Question Title

* 13. Is there anything else you think the Town should consider about stormwater

Next Steps

In the next stage of the process, the project team will:

Identify multiple solutions
Compare and evaluate solutions using criteria
Recommend final solutions

The project team will present a preferred approach, as well as the results of the evaluation at Public Information Centre (PIC) 2, which will take place in the winter of 2026/2027.
