Green Stormwater Infrastructure Is Having Its Day

Not long ago, systems engineered to manage and mitigate stormwater runoff were predominately of the “gray” variety: pipes, pumps, concrete-lined ditches and manmade detention ponds. Gray stormwater infrastructure systems collect water running off of impermeable surfaces such as roads and parking lots and move it, ultimately, to a local body of water. Today, however, more and more municipalities are embracing green stormwater infrastructure (GSI).
