Following Hurricane Sandy, Staten Island’s south shore, particularly Tottenville, needed protection from wave energy and erosion while also addressing long-term ecological degradation. The area had lost much of its natural coastal defense due to dredging and the historic decline of oyster reefs, creating a clear need for climate adaptation solutions that could combine coastal protection, ecological restoration, and community engagement.

The Living Breakwaters are widely regarded as a benchmark for nature-based coastal resilience, combining structural functionality with ecological and community value. By integrating eco-engineered armor units and tide pools into offshore breakwaters, the project reduces wave energy and erosion while creating complex marine habitats, including “reef ridges” and “reef streets” that support oysters, mussels, and other native species. It also enabled an almost entirely on-site mitigation approach, helping reduce in-lieu mitigation fees by approximately 80%. (Image: Biological growth on Armor Blocks)
On-Site Mitigation
By adopting an almost entirely on-site mitigation approach, the project reduced mitigation penalties by approximately 80% – about USD 14 million, or roughly 15% of total project costs.
Collaborative Design
ECOncrete collaborated with the multidisciplinary project team led by SCAPE, alongside WSP, Arcadis, COWI, and MFS Consultants.
Oyster Restoration Targets
Breakwaters were designed to support biodiversity restoration and integrate oyster habitats at scale.
Constructable Resilient Infrastructure
Solutions are compatible with standard precast and marine construction practices.
Community Outreach
Consultation and collaboration with local communities, schools, post-construction kayaking events etc.
