Reef Arch
An open-geometry marine structure for shorelines that need protection and room for habitat. Available from 50-lb units to site-specific configurations.
Thank you to Zulu Marine as the installer.


Florida’s coasts face erosion, rising seas and stronger storms. Living shorelines combine coastal structures with native plants to protect the edge while keeping it connected to nature.
Mangrove roots help hold sediment, soften waves and shelter young fish. Where conditions suit mangroves, Reef Arches can be part of a site-specific living shoreline that gives vegetation room to establish.
See it in the waterDesigned to attenuate wave action along vulnerable shorelines.
Open geometry encourages sediment recruitment over time.
Over 100 sq ft of surface area provides space for marine growth.
A minimal ground footprint and stackable design offer flexibility.
The Arch is engineered for the realities of the shoreline, yet its surfaces and openings create an entirely different relationship between infrastructure and habitat.
At the Ted Moorehead Lagoon House, a 150-foot breakwater shows how a purposeful structure can change the shoreline.


Good coastal ideas should not stall at the shoreline. We work with contractors and project teams to make deployment practical, adaptable, and efficient.
Our Low Profile Deployment System helps crews place Reef Arches without a barge.
Stackable units and a small ground footprint offer options for different site conditions.
Rapid delivery and permitting capability help project teams keep moving.
