Coastal protection
The Dutra Group is at the forefront of protecting America’s coastlines from the increasing threats of erosion, sea level rise, and extreme weather events. Our coastal protection work not only defends vital infrastructure and communities, but also preserves the natural buffers that sustain ecosystems and biodiversity along the nation’s shores.
From constructing robust seawalls, breakwaters, and revetments to restoring dunes, marshes, and barrier islands, Dutra delivers comprehensive solutions tailored to the dynamic forces of coastal environments. We integrate proven engineering with environmental sensitivity, ensuring that every project enhances both human safety and ecological function.
Whether it’s reinforcing military bases, safeguarding urban waterfronts, or rehabilitating storm-damaged coastlines, our team brings decades of experience, a specialized marine fleet, and a deep commitment to resilience. Working closely with government agencies, engineers, and environmental groups, we build with the future in mind—helping to secure America’s coastlines for generations to come.
