The birthplace of NYC’s maritime economy, the Financial District and Seaport sit at the intersection of Lower Manhattan’s transportation systems, economy, and civic life—a gateway for workers, residents, and visitors from across the city and world, currently at profound risk of climate change. Developed with two city agencies and a large, multidisciplinary team, the vision proposed in FiDi-Seaport Climate Resilience Master Plan seamlessly integrates flood risk reduction infrastructure into a publicly accessible, multi-level waterfront. Synthesizing feedback from two years of virtual and in-person engagement, the plan balances the aspirations and needs of an extraordinarily diverse group of residents and stakeholders. Layering benefits—risk reduction benefits with restored ecosystems, resilient maritime assets, and new public amenities—the plan envisions a more vibrant and active 21st century waterfront while preparing it for a climate-changed future.
