Building Lower Manhattan’s Coastal Flood Defense

Thursday, June 4, 2026

Construction is advancing on one of Lower Manhattan’s most significant resiliency infrastructure projects. Union contractors and carpenters with the New York City District Council of Carpenters are building the South Battery Park City Resiliency Project, a $231 million flood protection system designed to safeguard Lower Manhattan from storm surge and rising sea levels as part of the broader Lower Manhattan Coastal Resiliency initiative.

The first sections of reinforced concrete flood walls have now been formed and are being clad in stone between Pier A and Battery Place near the intersection of Broadway and State Street. The project will create a continuous protective barrier extending from the Museum of Jewish Heritage through Wagner Park and across Pier A Plaza. Construction is also progressing on South Cove and the South Esplanade as work advances into the next phases.

Across the site, union contractors and carpenters are performing concrete work, pile driving, marine construction, civil site improvements, and specialty installations. When complete, the project will provide a critical layer of protection for Lower Manhattan, helping safeguard neighborhoods, businesses, and public spaces against future coastal flooding.
