The storm surge from 2012’s Superstorm Sandy caused debilitating damage to track infrastructure and maintenance shop buildings throughout the New York Metropolitan region. At New York City Transit’s (NYC Transit) Coney Island Yard – one of the largest rapid transit repair shops in North America – more than 50 percent train storage capacity was lost in the storm’s aftermath. 

NYC Transit contracted with STV to assess damages and perform designs for interim repairs. The firm was also tasked with developing a comprehensive flood resilience program. Following the design of several short-term protective measures, STV prepared a feasibility study that evaluated various permanent flood mitigation alternatives based on cost, constructability, maintenance requirements and schedule to implement. STV then prepared final designs for a three-mile-long flood wall, multiple flood gates, underground water storage, and pump pits.
