New renderings have been revealed of the Hudson River Park Trust’s plans to transform the mostly vacant, 800-foot-long Pier 26, located in the Hudson River off TriBeCa, between North Moore and Hubert streets, into a public park. The $30 million overhaul would include a maritime education center, known as an estuarium, multiple landscaped areas with different kinds of vegetation, walking paths, seating, and playgrounds. The overhaul is getting equal financing from the city, the Lower Manhattan Development Corporation, and Citigroup, through a donation. OLIN Studio, a landscape architecture firm, is designing much of the pier, although Rafael Viñoly’s firm is designing the estuarium building. The plans are not final, although construction is anticipated to begin in roughly a year, Tribeca Citizen reported.
