How to apply
You’ll need to provide a PDF copy of your site plan. Site plans must be stamped by a Professional Engineer or the Association of Ontario Land Surveyors. The site plan must show:
- Pipe diameter, length and slope
- Basement floor elevation
- Elevation of storm sewer
For residential properties, the basement elevation must be 1 metre higher than the connecting storm sewer. This elevation must be verified. If not, a sump pump is the suggested method for drainage.
With commercial properties, methods to control stormwater that delay flow into watercourses must be in place. Examples include roof control, underground storage tanks and lot ponding.
