MTA NYCTA Critical Infrastructure Flood Resiliency Program

New York, NY

In 2012, Hurricane Sandy revealed MTA-NYCT’s critical infrastructure vulnerabilities to flooding and served as a catalyst to develop flood mitigation measures to strengthen, reinforce and mitigate consequences of a 50-to-100-year storm event.

Flood mitigation measures included correction and repair of structural faults and the design and installation of permanent floodwalls and plank barrier systems to resist the rising flood waters. The team also provided costs to elevate isolated infrastructure and communication buildings, above flood elevations and a new wet flood-proof foundation system.
