Overview of Stormwater Rules in Vancouver

Vancouver, British Columbia regulates stormwater to protect waterways, reduce flooding and manage runoff from development and repairs. The City publishes technical standards and expectations for on-site stormwater management and illicit discharge prevention; see the City of Vancouver stormwater guidance for design and permit expectations City of Vancouver stormwater guidance[1].

Owners and contractors must plan for runoff controls early in design and construction.
  • Stormwater management plans required for many developments and redevelopment projects.
  • Site-level controls: bioswales, infiltration, rain gardens, and retention tanks where required.
  • Construction best practices to prevent sediment and pollutants entering the storm system.
  • Maintain post-construction systems for ongoing compliance.

Design Standards and Approvals

Designers should follow the City of Vancouver technical guidance and submit required documents with development or building permit applications. Specific technical checklists, modelling requirements and drawing standards are available from the City’s stormwater pages and may be referenced on development permit checklists City of Vancouver stormwater guidance[1].

  • Integrate stormwater plans into permit submissions and early consultations.
  • Security deposits or maintenance agreements may be required; check project-specific conditions.

Penalties & Enforcement

Enforcement of stormwater and illicit discharge rules is handled by City enforcement staff and by-law teams; for complaint reporting and enforcement contacts see the City By-law Enforcement pages City of Vancouver By-law Enforcement[2]. The official enforcement pages should be consulted for complaint submission, inspection powers and contact procedures.
