My interest in Green Infrastructure (GI) sparked several years ago, when I worked as a college intern with the City of Greensboro, NC Stormwater Department. Back then, no one really talked about “green infrastructure”, but the city was invested in managing its stormwater. As part of that experience, I was given my first look at stormwater management in practice as I tagged along with city staff to inspect Greensboro’s Stormwater Best Management Practices (BMPs) – features like constructed wetlands, forested stream buffers, and rain gardens, that are designed to remove pollutants from urban runoff.
This week I was reminded just how much things have changed since that first internship experience. For one, “green infrastructure” has emerged as the preferred term for these kinds of features, and has also grown as an accepted stormwater management practice among communities across the country. Even at the federal level, acceptance of GI is very clear. For example, the 2014 amendments to the Clean Water Act now include section 603(c)(5): “for measures to manage, reduce, treat, or recapture stormwater or subsurface drainage water;” language which the EPA interprets as including “green roofs, rain gardens, roadside plantings, porous pavement, and rainwater harvesting.” EPA’s recent Community Summit on Green Infrastructure in Cleveland, Ohio highlighted this shift and offered an unparalleled opportunity to capture conversations from those on the ground about lessons learned and emerging implementation issues.
