The Coonamessett River in Cape Cod has seen declines in fish populations and degradation to aquatic habitat from a history of mill construction and cranberry cultivation. The Town of Falmouth removed one of the dams on the river, restored a bog to wetland conditions, replaced two undersized culverts, and rerouted flows around another dam. 

With a growing push to remove low-head dams due to safety concerns and the potential for ecosystem improvement, Corydon, Indiana was approached by The Nature Conservancy to remove two dams owned by the Town. The dams blocked potential habitat for the endangered hellbender salamander.

The Dolores River Restoration Partnership (DRRP) is a public-private collaborative working to restore ecosystems and plant communities in the Dolores River corridor. Invasive plants in this region have degraded habitat for both native plants and wildlife, increased wildfire risk, and negatively impacted recreational opportunities. The project has four broad goal categories: ecological, social, management, and economic. 

In Midland, Michigan a former ash pond for a coal-fired powerplant is located within the floodplain of the Tittabawssee River. Instead of the traditional (and expensive) cap and long-term maintenance plan, Dow's corporate nature team removed the ash and restored the area to a conservation wetland.  

The U.S. Army Corps of Engineers established a 5-hectare marsh on Drake Wilson Island off of the coast of Florida in 1976. This was one of the earliest beneficial use of dredged material projects for habitat enhancement. For more than 40 years, this marsh has created recreational opportunities and reduced erosion. 

The New Orleans district of the U.S. Army Corps of Engineers is strategically placing dredged sediment from the Mississippi River federal navigation channel to restore marsh habitat, improve and ensure the integrity of the navigation channel, and promote sediment deposition in the bay. 

A dam placed in Dry Creek in Sonoma County, California degraded important fish habitat. Instead of building an expensive and unattractive bypass pipeline, the Dry Creek Ecosystem Restoration Project restored 30 hectares of stream, floodplain, and riparian habitat. This project increased in-stream habitat complexity and improved hydrologic connectivity with the floodplain.  

The 21st Avenue West Channel Embayment of the Duluth-Superior Harbor is the site of shoreline habitat restoration. Dredged materials were placed in three locations of the embayment to restore shallow aquatic habitat, with the hopes of contributing to the delisting of the St. Louis River Estuary as an Area of Concern. 

The Duwamish Estuary in Seattle, Washington has been subject to heavy industrial development and pronounced anthropogenic disturbances associated with the Port of Seattle and other commercial facilities along its waters. This project sought to restore intertidal wetlands at three sites in the estuary, and to thereby enhance public access to the river and create vital habitat for several important species.

Terminal 117, a former industrial and superfund site along the Duwamish River, was transformed into the Duwamish River People’s Park and Shoreline Habitat. This project cleaned up a contaminated site, restored natural and stable shoreline habitat, and created river access in a historically marginalized neighborhood. 

The Nature Conservancy led the project to restore 7,100 acres of farmland to functional flood plain and return its ability to sustain native plant and wildlife species. In 2007, 180,000 trees, 8,000 pounds of seed, and 90,000 upland shrubs and trees have been planted in 1,400 acres of Emiquon.

The north branch of the Chicago River that runs through Eugene Field Park has been channelized and relocated, and had its riverbed paved with concrete. This led to increased flooding, marsh habitat loss, and vegetation loss. This project restored the wetlands and planted native vegetation. 

Clear Lake City, TX has a history of intense flooding from hurricanes and other storm events. Exploration Green is a project to transform a former 200-acre golf course into a public park and flood-control area. The park will have 5 detention basins to store floodwater during storm events. 

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.  

The Fort Sheridan Restoration Project restored 84 hectares of ravines, riparian woodlands, coastal bluff, beach, dunes, and lacustrine habitat along the coast of Lake Michigan. This project aimed to connect coastal habitats, restore native plant communities, and increase resilience along the coast. 

The Fowl Meadow Purple Loosestrife Biological Control Project is a five-year collaborative wetland restoration project in the Neponset River Watershed, Massachusetts. The project uses Galerucella calmariensis and G. pusilla beetles and larvae as a biological control agent to control and reduce the presence of exotic, invasive Purple loosestrife (Lythrum salicaria).

Galloway Creek, a tributary to the impaired Clinton River in Michigan, provides cold-water base flows that support trout species. Development led to a straightened, degraded, and disconnected creek that runs through a golf course. This project restored floodplain connectivity, improved geomorphic stability, and built in-stream habitat for fish species and aquatic wildlife. 

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. 

As temperatures and pests change, urban ecosystems will need to adjust and will become ever more important for public health and quality of life. In 2012, the City of Goshen completed an urban tree canopy inventory and assessment in order to understand what trees are in the community and how they will be impacted by environmental changes.

Grassy Point is a 100-acre wetland where the St. Louis River meets Lake Superior. It used to be home to several sawmills which unfortunately left debris behind to clog up the waters. This project eventually removed 11,000 cubic yards of wood debris from the site and reformed several channels during 1994-1996.
