Stormwater Management Master Plan
As part of the Lake Simcoe Protection Plan (LSPP), The Town of Innisfil must have a Stormwater Management Program. Our Stormwater Management Master Plan ensures stormwater is sustainably managed to protect our water supply and environment.
Notice of study
We're updating our Stormwater Management Master Plan to develop long-term strategies to manage stormwater runoff while improving and maintaining the Town's water resources. At the same time, we're completing a flooding strategy to identify and prioritize areas of concern so we can find cost-effective, sustainable and innovative solutions.
Feedback
The update to the plan ensures we remain compliant with the LSPP while accounting for growth in Innisfil over the next 20 years. Results from the study will be made available for public review. We'll look for your feedback throughout the study process. Follow our Get Involved Innisfil page for updates on how to participate.
Goals and objectives
The Stormwater Management Master Plan aims to improve stormwater drainage to minimize:
- Erosion
- Phosphorous loading
- Changes in water balance
Recommendations
Recommended actions in the Master Plan include:
- Stormwater pond clean-outs and retrofits
- Using low impact drainage methods, such as rainwater gardens, enhanced grass swales and permeable pavements
- Adding oil grit separators upstream of the ponds
- An inspection and maintenance program, including stormwater facility inspection, replanting dead vegetation, removing beaver dams and more
