In December 2014, BGI’s West Street Watershed Stormwater Project proposal was accepted by the Greenpoint Community Environmental Fund (GCEF). The project proposes to design and install 54 right-of-way bioswales and greenstreets covering 4,845 sq. ft. on the ten streets that slope toward West Street and the East River between Manhattan Avenue and Franklin Street.

Major project activities include: Community engagement in site selection and project design; Site assessments and selection; Design, construction,  planting and maintenance of bioswales and greenstreets.

The project will result in a substantial decrease in the volume and frequency of raw sewage releases from the city’s combined sewer system by installing bioswales and greenstreets “bulb outs” on sidewalks and streets in the area bounded by Franklin Street and Manhattan Avenue, and Green and Calyer Streets. This green infrastructure will capture and treat over 6 million gallons of stormwater annually, or 35% of the stormwater from the project area that otherwise would contribute to sewer overflows and pollute the East River. Combined with the West Street high level sewer, the overall project will remove over 10 million gallons of stormwater from the combined sewer system annually, approximately 39% of the stormwater falling on public rights of way in the entire West Street surface watershed.
