Placement of the third breakwater will begin later this year. The first two breakwaters will be completed in 2022. The project also promotes social resilience through local educational programs led by the Billion Oyster Project (BOP) and the open-access Living Breakwaters Curriculum developed by BOP and design team lead SCAPE Landscape Architecture.Īlready, the construction team has finished production of all ecologically-enhanced concrete and tidepool units that will be placed in precise locations to enhance ecological habitat. The eight breakwater structures, placed 1,000 feet offshore, are designed to break wave intensity, reverse beach erosion, and restore and enhance marine habitats. The project broke ground in September 2021 and will include 2,400 feet of breakwaters, which are partially submerged structures composed of marine stone and biologically enhanced concrete designed with “reef ridges” and tidal pool units to provide habitats for oysters and other marine life. The final project design has been adjusted from the original competition proposal and received city, state, and federal agency approval. These iterations were shared with the local Citizens Advisory Committee (CAC) for review and community input. The SCAPE team conducted extensive hydrodynamic modeling and engineering analysis of the breakwaters to develop design scenarios. View the team’s full original proposal here. The vegetated dune system will be strengthened by the breakwaters, to provide a layered system of protection. Living Breakwaters is designed to work in concert with other ongoing resilience initiatives in the area, including the New York Rising Community Reconstruction Tottenville Dune and Coastal Dune Plantings project. The team’s work with the Harbor School and the Billion Oyster Project will bring educational opportunities for local school groups, teaching the next generation of ecological stewards about protecting Staten Island’s fragile coastline. The structure will provide habitat to the Raritan Bay’s rich ecosystem of marine life, and an on-land Water Hub will be constructed with space for visiting groups, recreational activities, and educational programs. The proposal envisions a “necklace” of offshore breakwaters that will reduce risk, revive ecologies, and connect residents and educators to Staten Island’s southeast shoreline. The current version of BREAKWAT is version 3.3.0.24.The Living Breakwaters competition concept was conceived to connect physical, social, and ecological resilience. In the future, BREAKWAT will be updated with new design formulae based on recent and future laboratory and field research. New developments in the design of coastal structures, as well as software developments in general have been incorporated in BREAKWAT. Since then BREAKWAT has been widely used by a large group of users at contractors, engineering companies, universities, research institutes, etc. The first version of BREAKWAT has been released by WL | Delft Hydraulics (the predecessor of Deltares) at the end of the 1980’s. Rubble mound breakwaters with armour layers of rock material or concrete units, berm breakwaters, vertical caisson structures, reef type structures and near-bed structures can be designed using BREAKWAT up to a conceptual design stage. BREAKWAT is a conceptual design tool for several types of coastal structures under wave loading.
