dD+P oversaw intensive station rehabilitation and flood protection improvements for the South Ferry Station at South Street & Whitehall Street after Superstorm Sandy.
Sandy affected the New York City Transit (NYCT) subways at an unprecedented magnitude. Downtown Manhattan facilities in low-lying areas were particularly affected. The rehabilitation of South Ferry served to recover the capacity of this high traffic station while preventing future flooding.
dD+P conducted an architectural assessment that included all concourse, mezzanine, and platform levels, employee facilities, back-of-house spaces, as well as mechanical and electrical rooms throughout the station complex.
Our assessments resulted in reports documenting the conditions and recommendations for recovery, rehabilitation, and mitigation required for a category two hurricane. The team then prepared alternative designs that balanced costly permanent flood mitigation with more economical components that could be deployed prior to a storm event.
New flood doors and panels were installed as well as watertight glazing and stop log barrier walls, which addressed various additional station conditions. These measures, while responding to current and future needs, also offered an opportunity to redesign three new prominent (and flood-proof) pavilion entrances.
