Flood mitigation improvements for battery park and west street underpasses in manhattan- ER event #NY 1301

The Federal Highway Administration (FHWA) awarded $29,962,804 to the New York State Department of Transportation on July 14, 2025, under the Highway Planning and Construction program (CFDA 20.205) to deliver flood mitigation improvements for the Battery Park and West Street underpasses in Manhattan. This Project Grant, designated as Hurricane Sandy Emergency (ER) Event #NY13-01, specifically addresses drainage deficiencies by installing flood mitigation improvements and modifications throughout both tunnel systems extending from Battery Place to the FDR (Franklin D. Roosevelt Drive) in New York County.

The project represents critical resilience infrastructure development following Hurricane Sandy impacts, focusing on enhanced drainage capacity and structural modifications to prevent future inundation in these strategically important Manhattan transportation corridors. As a state-administered transportation project, NYS DOT is responsible for executing the design, environmental compliance, and construction oversight in accordance with federal Highway Planning and Construction program requirements, including environmental review under the National Environmental Policy Act and compliance with applicable federal regulations.
