    New York Lets a Thousand Bioswales Bloom

    In an effort to curb sewage overflows, New York City has turned to green infrastructure: right-of-way bioswales, green roofs and rain gardens, among other practices. These measures help decrease stormwater runoff by increasing pervious areas and introducing water-loving plants that can absorb some of the water and encourage evaporation.
