• 7th Avenue B/Q station, Park Place and Carlton Avenue: 8:00AM to 10:00AM on Wednesdays, sponsored by the Brooklyn Botanic Garden's NYC Compost Project.
• Grand Army Plaza Greenmarket: 8:00AM to 3:30PM on Saturdays, sponsored by GrowNYC and its community partners.

Both locations accept food waste year round.For a map of all compost drop off locations, see the Department of Sanitation web site.

Through October 2015, residents can also drop off organics and food waste for composting at the Prospect Heights Community Farm, located on St. Marks Avenue between Vanderbilt and Underhill Avenues. For hours of operation and drop off rules, click here.

The New York City Department of Environmental Protection (DEP) is undertaking a number of projects aimed at improving water quality in the Gowanus Canal. Several of these projects are intended to reduce combined sewer overflows (CSOs) into the canal. CSOs are prone to occur during heavy rains when stormwater overwhelms the capacity of the local sewer system.

Because Prospect Heights is part of the watershed for the Gowanus Canal, DEP plans to install a network of bioswales to absorb stormwater. Bioswales are tree pits with a curb cut to absorb runoff.
