Introduction

Sound Impacts is an online portal for all of the region’s practitioners and implementers of Green Infrastructure as well as for anyone curious to see what efforts and investments are being made to protect and improve this region’s natural assets.

  permeable pavement

Permeable pavement is a type of hard surface ground cover that is porous, allowing rainwater to pass through into the ground beneath. This system mimics the process that would occur when rain falls onto natural surfaces, such as a forest floor. Permeable pavement can also trap suspended solids and pollutants, which allows for cleaner water to returned back to underground aquifers.
