This project aimed to restore oyster populations in Pensacola Bay, St. Andrews Bay, and Apalachicola Bay in Florida. This project placed 49,000 cubic yards of cultch material over 210 acres of previously constructed oyster bars. This project hoped to maximize oyster larvae settling and oyster colonization at each restoration site. 

This project built a living shoreline at Project GreenShores Site II in Pensacola Bay to reduce erosion, provide shoreline protection, and create both reef and salt marsh habitat. The constructed breakwaters created 9 acres of salt marsh habitat, and 4 acres of reef habitat. 

Two hurricanes in 2004 destroyed Fort Pierce, Florida’s waterfront. This waterfront is a public access space that includes a park and a marina. The city and Tetra Tech Inc. developed a 6-hectare island breakwater system that will protect the city under current conditions and adapt to projected sea-level rise.

Marine Corps Base Camp Lejeune, near Jacksonville, North Carolina contains over 2600 acres of coastal wetlands that are at risk of drowning due to sea-level rise, low elevation, and limited sediment supply. This project served as an experiment to determine viability of thin-layer placement for marsh restoration in similar locations.  

Dredged material was used to nourish the beach at 61st Street on Galveston Island, TX. This project increases recreational opportunities on the beaches and increases tourism to Galveston and nearby Houston, TX. This project is part of a long-term strategy to provide storm protection, increase property value, and reduce erosion. 

Goldbug Island, off the coast of Charleston, SC, was experiencing erosion and salt marsh loss. To prevent further loss, the Nature Conservancy constructed a 67-meter-long oyster castle reef. This reef prevents erosion, mitigates wave energy, enhances biodiversity, and with increased oyster settlement, will improve water quality. 

This project created 335 acres of marsh and 28,342 linear feet of earthen containment dike in Bayou Grande Cheniere, Louisiana. This project utilized sediment materials from the Mississippi River borrow areas. This marsh and containment dike will enhance biodiversity and coastal protection from erosion and wave action.  

The Nature Conservancy restored a 54-acre oyster reef in Matagorda Bay, Texas. This project successfully restored large, thriving oyster reefs that have enhanced biodiversity in the bay. This increase in biodiversity has improved recreational fishing opportunities and fishing-related tourism in the area. The increase in fishing at Half Moon Bay reef adds around $691,000 to Texas’ gross domestic product annually.  

The Hamilton Wetlands Site, just north of San Francisco, was diked and dried almost a century ago for commercial development. This loss of marsh impacted endangered species and lessened the area’s coastal resilience. This project is restoring marsh functions and ecosystems, as well as creating recreational opportunities. 

Hancock County Marsh Coastal Preserve was the fastest eroding marsh in Mississippi. To reverse this loss and improve the preserve, this project constructed three habitat-restoration components: a 10-kilometer segmented living shoreline, 19 hectares of restored intertidal marsh, and a 19-hectare subtidal reef in Heron Bay. 

The Herring River Restoration Project in Massachusetts will replace the restrictive dike at the mouth of the river with a bridge that will allow tidal water to flow freely between the river and Wellfleet Harbor. This will restore the biodiverse, productive, estuary that existed pre-dike construction.  

This project was conducted in Brunswick, Georgia to evaluate the recovery response of salt marsh vegetation and impact of selected species upon thin layer placement of dredged materials. The study found that marsh elevation could be altered through thin layer placement of dredged material without loss of the functional values. 

This project will restore 295 acres of tidal marsh that had severely degraded from erosion, subsidence, storms, and canal and pipeline construction. Marsh restoration will reduce risks from storms and sea-level rise, and improve the coastal resiliency of communities in the Parish.  

Big Egg Marsh in Jamaica Bay, NY was experiencing subsidence, erosion, plant mortality, isolation, and other threats related to sea-level rise. This marsh, adjacent to Broad Channel village, was chosen for a thin-layer placement restoration project to increase marsh elevation and vegetation. The site was restored to a silty-organic saltmarsh. 

The U.S. Army Corps of Engineers completed a thin-layer placement of dredged material project at Jekyll Creek, Georgia. This project added dredged material to a subsiding, threatened coastal marsh. This project, covering 2 hectares, supports a variety of wildlife and native marsh grasses, and creates a more resilient coastal system.  

The Kenilworth Marsh tidal wetland restoration project, led by the National Park Service, aimed to restore areas in Washington, D.C. that were degraded from altered hydrology and contamination. The project team placed 130,000 cubic yards of dredged material to restore hydraulic function of the tidal marshes, installed over 350,000 native plants, and removed invasive purple loosestrife and phragmites.

Kerry Island is a part of the Lower Columbia River Estuary in Oregon, and has been severely degraded by agriculture and industrial development. The Columbia Land Trust acquired the land and removed a levee to restore tidal fluctuations. They also restored marsh habitat, improving populations of important fish species. 

King Fisher Beach in Port O’Connor, Texas is a major destination for tourists and local recreation. It is increasingly susceptible to the impacts of storm surge, sea-level rise, and erosion. The U.S. Army Corps of Engineers nourished King Fisher Beach with 58,305 cubic meters of dredged sediment.
