What is Grey to Green?

What is Green Infrastructure? 

Green infrastructure consists of both natural systems such as forests and wetlands, as well as vegetative technologies like green roofs and green walls, and the products designed to support growth such as engineered soils, cisterns and irrigation systems.

Green infrastructure technologies also include bioswales, meadows, engineered wetlands, planting beds, turf and permeable pavements. All of these living green infrastructure elements create a system in your community that greatly support quality of life.

is green infrastructure important? 

There are many economic, social and environmental benefits of green infrastructure including job creation, stormwater management, support for biodiversity, reduced air and noise pollution, and improved marketability of buildings. 

A video from Green Infrastructure Ontario's multi-part series on Green Infrastructure in the City focusing on how green infrastructure is defined.

“Green infrastructure allows a local government to make the most of limited public dollars and achieve multiple goals with a single investment.”
— Environmental Protection Agency, "Enhancing Sustainable Communities with Green Infrastructure" (2014)
