The Dutra Group is a leader in beach renourishment and the restoration of marshes and wetlands—projects that not only protect coastlines from erosion and storm damage but also revive critical habitats that support biodiversity and water quality.
Our team works closely with federal, state, and local partners to design and deliver large-scale coastal restoration efforts. Using precision dredging, strategic material placement, and native vegetation, we rebuild barrier beaches, replenish shorelines, and reestablish tidal marshes and wetlands that serve as natural buffers against rising seas and extreme weather.
With deep experience in both engineered and nature-based solutions, Dutra combines environmental sensitivity with construction expertise. From restoring storm-damaged beaches to rebuilding wetland ecosystems, we help create resilient coastlines that serve both people and the planet—today and for generations to come.
