The New York City Economic Development Corporation and the city’s Department of Parks and Recreation have issued a request for proposals, or RFP, for the creation and operation of new rides, games and other attractions in Coney Island. Specifically, the RFP includes 150,000 square feet of space on five vacant lots along the boardwalk between West 10th and 16th streets that make up Amusement District. Proposals are due mid-March, and the city is hoping the new amusements open by summer 2018 — just in time for tourists and thrill seekers.
