What is permeable, pervious, or porous pavement?

Permeable, pervious or porous surfaces are types of pavement with a high porosity that allow rainwater to pass through into the ground below.

Permeable paving can be one part of building green parking lots, which can also include rain gardens, art, trees, solar covers, and other creative elements.

According to the Environmental Protection Agency, permeable pavements can also help reduce flooding of building foundations and ponding of water on driveways, sidewalks and patios.

Ontario-based Random Acts of Green, a women-led social enterprise, recently published a blog post entitled “6 Ways Permeable Pavement Benefits the Earth”.
