Also in 2017, the New York City government published plans to construct two combined sewer overflow facilities along the canal to help with stormwater management. The first facility, the "Head End Site", is to be at the very north end of the canal on the eastern bank. The facility, located adjacent to an existing manufactured gas plant site, would handle sewage from the Red Hook Watershed, which comprises the land around the canal's western bank and north of the canal's head. The second facility, the "Owls Head Site", is to be at Second Avenue and Fifth Street, where the Fourth Street Basin splits off the rest of the canal. It would clean the water from the Owls Head watershed, which constitutes the land from the eastern bank to Prospect Park. These new facilities are required as part of an agreement between the city and the EPA.
