Riverbank State Park

Story

Riverbank State Park is a 28acre state park built on the top of a sewage treatment facility on the Hudson River, in the New York City borough of Manhattan.On September 5, 2017, the park was renamed Denny Farrell Riverbank State Park, after a longtime member of the New York State Assembly who represented the area around and near the park.Park facilitiesRiverbank State Park was designed by Dattner Architects and Abel Bainnson Butz Landscape Architects and opened in 1993. The original idea for a park atop the sewage plant was Phillip Johnson's. It is located on the West Side Highway from 137th Street to 145th Street in Upper Manhattan, 69ft above the Hudson River.The park was built over the North River Wastewater Treatment Plant, which processes 125e6USgal of wastewater every day during dry weather, and is designed to handle up to 340e6USgal a day when the weather is wet. In order to minimize odors emitted by the plant, dedicated odor-control facilities have been installed at the plant, including $55 million in recent upgrades. The plant sits on 2,300 caissons pinned into bedrock up to 230ft beneath the river. Construction of the foundation was completed in 1978, and the wastewater treatment facilities were constructed in two phases between 1986 and 1991.
