New York City Explores 'Green' Infrastructure Approaches to Reduce Sewer Overflows

摘要

The new york city Department of Environmental Protection (DEP) recently unveiled two innovative storm-water management projects intended to reduce the amount of runoff entering the city's overburdened combined sewer system. The two projects-an integrated "blue and green" rooftop system in the Bronx and a planned bioretention area adjacent to the Gowanus Canal in Brooklyn-may end up serving as templates for the DEP as it seeks to carry out its ambitious plans for decreasing combined sewer overflows and improv- ing water and air quality throughout the city.
