There are plans for a new storm barrier along the southern third of the greenway, between West 57th and East 42nd Streets. The final proposal, which is geographically U-shaped, will include many features. Under the elevated FDR Drive structure above South Street will be storm barriers hanging from the viaduct's ceiling, which will drop down in case of a storm. A "Battery Berm" will be located at Battery Park, and a maritime museum will be opened on the site of a former Coast Guard building there. The proposal, by Rebuild by Design, will also include components for storm barriers in Hunts Point, Bronx and on Staten Island.
