Green infrastructure: sustainably managing our rainwater

We have a target to capture and treat 90% of Vancouver’s average annual rainfall by using green infrastructure tools and design guidelines on public and private property. 

In the natural environment, rain is absorbed and filtered by plants and soils. In cities, this natural water cycle is disrupted and rainwater flows across pavement and rooftops.

This water picks up pollutants which end up in our waterways causing negative impacts on water quality and wildlife.

Green infrastructure brings nature into the city, to capture and clean our rain water before returning it to our atmosphere and our surrounding oceans and rivers.

Rain City Strategy

We are working on a strategy to:

  • Improve water quality
  • Enhance Vancouver’s resiliency and climate change adaptation
  • Use rainwater as a resource
  • Support neighbourhood livability and biodiversity

Shaped by water

Several members of our engineering department toured the Netherlands to learn more about the green infrastructure and water technologies.

Vancouver's Rain City Strategy

We've has set a target to capture and treat 90% of Vancouver’s average annual rainfall by using green infrastructure tools and guidelines.

Our vision: Vancouver’s rainwater is embraced as a valued resource for our communities and natural ecosystems

What is green infrastructure

Green infrastructure mimics natural water processes. It works with plants, soils, trees, and built structures to capture and clean rainwater before returning it to our waterways and atmosphere.


Green infrastructure features

By City of Vancouver

View different types of green infrastructure around the city.

  • Green roofs

    By City of Vancouver

    These living roofs covered with plants and trees collect, absorb, and return rainwater to our atmosphere. Green roofs provide habitat for wildlife and pollinators.

  • Rain-friendly streets

    By City of Vancouver

    Porous pavement absorbs rainwater and soil cells store water and create space for tree roots to grow and absorb water beneath our sidewalks and traffic lanes.

  • Swales

    By City of Vancouver

    Swales are shallow channels alongside roads that use soils and plants to direct and slow water allowing it to absorb into the ground and atmosphere.

  • Rain garden

    By City of Vancouver

    These gardens are sunken into the ground and lined with native plants, grasses, trees, and stream beds that absorb and clean rainwater that runs off our streets and sidewalks.

  • Parks

    By City of Vancouver

    City parks are full of plants, trees, and flowers that soak up and clean our rainwater. They act like natural wetlands in our urban environment!
