NYC Subway Flood-Proofing: MTA's Action Plan

With flash floods posing a significant threat to NYC's subway system, the MTA is taking proactive steps to protect its infrastructure and ensure passenger safety. Recent incidents, like the flooding at the 28th Street No. 1 station, have highlighted the urgency of these measures.

MTA's Mitigation Strategies:

The MTA is implementing several key strategies:

• Elevated Subway Steps: These slightly raised steps prevent stormwater runoff from sidewalks and streets from directly entering subway stations. This simple yet effective solution is already being installed at various stations.

• Improved Drainage Systems: Enhanced catch drains on streets and along tracks are being implemented to redirect water away from subway entrances and tracks.

• Sealed Manholes: Manhole covers are being welded shut at vulnerable locations to prevent water from entering the system through these openings. This was a significant point of water entry in the recent 28th Street incident.

• Pumping Systems: The MTA continues to rely on its existing pumping systems to remove any accumulated water.

Additional Safety Advice for New Yorkers:

The city also issued safety guidelines for citizens:

• Relocate if necessary: Residents in basements, below-grade homes, or flood-prone areas are urged to move to higher ground.
• Monitor weather alerts: Stay informed about weather forecasts and warnings.
• Stay indoors: Avoid being outdoors during thunderstorms.
• Report downed power lines: Treat downed power lines as live wires and call 911.
• Move vehicles: Move vehicles to higher ground if in flood-prone areas.
• Clear gutters: Clear debris from gutters and drains to minimize localized flooding.

The MTA emphasizes that while these measures are in place, the unpredictable nature of intense rainstorms necessitates ongoing vigilance and adaptation. Their commitment is to minimize disruption and ensure the safety of subway riders during severe weather.
