What's new: July 25, 2023
To simplify rezoning applications, we are updating our rainwater management requirements. Review the requirements
Effective January 1, 2024, we will have simplified rainwater management requirements for certain new, private property developments. New Part 3 (complex) buildings in Vancouver will need to have rainwater management. The requirements will not apply to residential buildings with 8 or fewer units or to alterations of existing buildings. The Rainwater Management Bulletin PDF file (903 KB) will no longer be used.
What's the same
Water quality standards for discharged storm water remain unchanged. Review the details in the Sewer and Watercourse By-law (section 3) PDF file (346 KB).
The Groundwater Management Bulletin PDF file (1 MB), and its underlying by-law text, remain unchanged.
In Vancouver, rainwater runs off into our sewer system and can cause:
- Sewer overflows
To help reduce flooding and overflows, we:
- Need to look at ways to manage rainwater
- Are working with Metro Vancouver to improve the public sewer system
Private properties also have a role to play in keeping rainwater out of our sewers.
