9/23/25 | Climate Week Tour: South Battery Park City Resiliency Project - Pier A Plaza

Hosted by Sweet Group

10AM Start

Client: Battery Park City Authority

This project focuses on enhancing flood resiliency at Pier A Plaza and The Battery, two key public spaces in lower Manhattan. The scope of work includes the installation of a comprehensive flood barrier system designed to protect the area from future storm surges. This system will incorporate deployable flip-up gates, reinforced concrete walls to elevate the existing site grade, and exposed flood walls spanning the Battery Tunnel Underpass and the Brooklyn–Battery Tunnel.

In addition to flood protection measures, the project will involve selective demolition, regrading, and the reconstruction of specific landscape elements to ensure seamless integration with the new infrastructure while maintaining the park's historic and recreational character. As part of the NSI (Neighborhood Sewer Interceptor) work, an interceptor isolation gate will be installed within existing regulator structures. This gate will automatically close during flood events to prevent storm surge from rising through the interceptor line and flooding street-level areas.
