The coral communities in Culebra were stressed by recognized erosion from an unpaved parking lot and road that had increased the volume of post-rainstorm runoff carrying pollutants. Community members managed to slow the flow of rainwater through erosion and sedimentation control, reforestation and habitat restoration through dune restoration, restoration of the line permanent vegetation, and delineation of vehicular and pedestrian access.

Along the Morro Bay, the wetlands, intertidal mudflats, salt and freshwater marshes, eelgrass beds host some of the most productive natural habitats in the world. To protect the ecological significance of estuaries, stakeholders of the Morro Bay National Estuary Program in California worked with resources from the EPA's Climate Ready Estuaries program to identify their climate risks.

The coastal marsh habitat in Blair Island, San Francisco was impaired by construction of salt ponds and dirt levees before its ecological value was recognized. The project aimed to restore the 1, 400 acres of diked marsh to tidal marsh primarily by breaching the perimeter levees to allow tidal action via surrounding slough channels.

In 2003, NOAA led a partnership that restored a 0.8-acre salt marsh in Bar Beach Lagoon, North Hempstead, New York, as part of a natural resource damage assessment (NRDA) settlement addressing natural resource injury damages due to release of contaminants into Hempstead Harbor. 

This project aimed to create marsh habitat and restore a ridge at the Spanish Pass Increment of the Barataria Basin in Louisiana. Spanish Pass is a natural historic tributary of the Mississippi River with degraded channel banks and adjacent marsh. This project created 397 acres of ridge and 1,261 acres of marsh habitat.  

Barataria Basin, just south of New Orleans, Louisiana contains marshes that are rapidly subsiding from leveeing of the Mississippi River and loss of regular sediment depositions. The marsh received sediment from a nearby location to increase elevation and relieve plant stress. This restoration effort increased aboveground biomass and accretion rates. 

Bayou La Branche, originally a brackish marshland, was levied and pumped into farmland before flooded into a large, open-water pond after the 1915 Hurricane. USACE and Louisiana Department of Natural Resources aimed to re-create the marsh habitat with an area of 70% land and 30% water within 5 years of construction.

A tidal marsh in Bayou Lafourche, Louisiana was degrading due to subsidence and sea-level rise, as well as a drought-induced die-off of Spartina alterniflora. 7.5 hectares of marsh was restored using thin-layer placement of dredged material. Sediment placement improved the recovery of the marsh and increased plant biomass. 

This project created a living shoreline comprised of bioengineered, marsh-fringing oyster reefs. 11.5 miles of reef breakwaters, marine mattresses, and rock revetments were placed off the shoreline to establish the bioengineered reefs. This living shoreline will provide self-sustaining coastal protection from erosion, wave action, storm surges, and sea-level rise.

An eelgrass restoration program implemented by the Massachusetts Division of Marine Fisheries aimed to mitigate assumed impacts to marine resources resulting from the HubLine gas pipeline construction which transits the Harbor. The restoration was intended to provide important shallow-water eelgrass habitat to juvenile crustaceans, shellfish, and finfish which commonly inhabit sea grass meadows.

Brooklyn Bridge Park boasts 2 kilometers of shoreline and 14 hectares of open space that serves thousands of visitors per day. This industrial shoreline has lost natural intertidal habitats and biodiversity. The park constructed two ECO-concrete projects to enhance biodiversity:  concrete tide pools and repairing aging piles with eco-friendly substrate to recruit invertebrates. 

Brunswick Town–Fort Anderson is an important historic site on the North Carolina coast. To prevent further erosion and negative impacts from storms and sea-level rise, the North Carolina Department of Natural and Cultural Resources installed 140-meters of Reefmaker along the shoreline. This stabilized the shoreline and produces multiple co-benefits.  

A team of nonprofit organizations and government agencies led by the California State Coastal Conservancy developed preliminary design plans to use a gravel beach and berm in the Eden Landing Ecological Reserve to protect critical habitat, control erosion, and enhance shoreline resilience on the south San Francisco Bay.

Cape Lookout State Park, located in coastal Oregon, experienced extreme erosion and storm damage to its beach and infrastructure. Instead of a less aesthetic, more expensive, seawall or revetment, managers opted to build a cobble berm backed by an artificial dune to increase coastal protection and enhance the natural shoreline community. 

Cat Island and Ship Island are barrier islands off the coast of Mississippi that provide protection to coastal communities from erosion and storm surges. This project used millions of cubic meters of sand and reused dredged sediment to restore the islands’ beaches and dunes.  

The Cat Island Chain in Green Bay, Wisconsin was lost to erosion and storms in the 1970s. This project is rebuilding the islands using clean dredged material from a nearby navigational channel. This will create beach and wetland habitat for many species and support both sport and commercial fisheries. 

Florida’s Charlotte Harbor Estuary was established as national estuary under the 1987 National Estuary Program for its significance to wildlife and local economy. A 20-year Comprehensive Conservation and Management Plan (CCMP) was formulated to restore and protect the estuarine system. Restoration activities started in June of 2001

A collaborative effort from USFWS, USDA, and Maryland DNR has worked over 20 years to eliminate the exotic, invasive nutria, which, combined with sea level rise and land subsidence, have caused over 5,000 acres loss of wetlands. Working closely with public and private landowners, the project managed to remove 14,000 nutria and protect over 250,000 acres of marshes.

Oregon DOT designed several nature-based solutions to protect the 363-mile-long Oregon Coast Highway (U.S. 101) from extreme events and coastal bluff erosion. Three demonstration sites were selected, where cobble beaches were restored to enhance natural wave protection along the backshore.

Reef balls and oyster shells were used to create 1.02 miles of oyster reef off the coast of Coffee Island, in Portersville Bay, Alabama. These reefs reduced erosion, enhanced biodiversity, created jobs and improved local fisheries. This also created 20 acres of seagrass and marsh habitat, further protecting the shoreline.
