Southern Brooklyn’s sole remaining creek—once part of a salt marsh that extended all the way to Sheepshead Bay—was a major source of “backdoor flooding” during Superstorm Sandy in 2012.

Now plans for a ferry and other projects have raised concerns about dredging up contamination from the bottom of Coney Island Creek. The creek is used for swimming, kayaking, bird watching and fishing.

Dumping and raw sewage still plague the creek, so residents want to make sure access and pollution continue to be addressed.
