Greenpoint West Street Watershed: Phases I + II

This project proposes over 100 right-of-way bioswales and greenstreets covering three sewersheds in Greenpoint, Brooklyn. The overall scope includes engagement of the community in site selection and project design; performance of site assessments and selection; design, construction, and planting of bioswales and greenstreets; and maintenance of the plantings.

The installation of bioswales and greenstreets in the public right of way areas will substantially decrease the volume and frequency of raw sewage releases from the city’s combined sewer system. The green infrastructure will capture and treat over 12 million gallons of stormwater annually, 35% of the area’s stormwater that would otherwise contribute to sewer overflows and pollute the East River. Beyond these benefits, the added trees and vegetation will improve local air quality by capturing and storing carbon dioxide and other air pollution, and will lower the heat island effect.
