Environmental Groups Release New Reports on Green Infrastructure

On Oct. 30, the U.S. Environmental Protection Agency (EPA) released a report analyzing the economic benefits of green infrastructure. According to EPA, green infrastructure is economically beneficial when used where appropriate to supplement traditional stormwater infrastructure. The report includes 13 case studies that cover a variety of different cost-benefit analyses. It was prepared so that utilities, state and municipal agencies, and other stormwater professionals can better quantify potential benefits of a green infrastructure program.

The report’s release coincides with EPA’s Oct. 21 announcement of an updated green infrastructure strategy that outlines plans for the agency to use these techniques to capture stormwater runoff from newly built and redeveloped sites.

Earlier in October, the World Resources Institute in collaboration with Earth Economics and Manomet Center for Conservation Sciences released the report Natural Infrastructure: Investing in Forested Landscapes for Source Water Protection in the United States. The report identifies opportunities across the US to improve water quality by investing in forest restoration and conservation. It gives an overview of the current state of natural infrastructure approaches and provides lessons in program design and implementation.

October was a busy month for new reports, with the Natural Resources Defense Council also releasing an update to its Rooftops to Rivers report. The original report was released in 2011 to showcase the work of 20 cities using green infrastructure. The update shows how, in just two years, the profiled cities have made significant progress. In fact, three featured cities have improved their Emerald City ratings, including Pittsburgh, Milwaukee, and Tucson.
