Plumb Beach Brooklyn NY walking tour NYC New York City USA Fourth of July weekend summer 2 Plumb Beach is at Jamaica Bay where the Rockaway Inlet connects to the Atlantic Ocean as well as where Gerritsen Creek, Dead Horse Bay, and Sheepshead Bay connect with Jamaica Bay *** Plumb Beach Plumb Beach (sometimes spelled "Plum") is a beach and surrounding neighborhood along the north shore of Rockaway Inlet, in the New York City borough of Brooklyn. It is located near the neighborhoods of Sheepshead Bay and Gerritsen Beach, just off the Belt Parkway. Plumb Beach was originally part of a small island until Hog Creek was filled in during the late 1930s, connecting the beach to the rest of Brooklyn. Since 1972 it has been a part of Gateway National Recreation Area, though the parking lot and greenway that provide primary access to the shore are the responsibility of the New York City Department of Parks and Recreation and the New York City Department of Transportation. The neighborhood is part of Brooklyn Community District 15, although a section of the beach is not part of a Community District. In May and June, horseshoe crabs climb onto the beach to mate. That beach is often subjected to heavy beach erosion, as incoming storms often blow large amounts of water up the Rockaway Inlet past the beach into Jamaica Bay. In the summer, the beach attracts kiteboarding enthusiasts, as the southerly sea breeze makes the area ideal for this use.
