In 2007 the Anacostia Watershed Society (AWS) initiated an experimental research project, called the 38th St. Bridge Project, on the rip-rap slope along the streambanks in order to demonstrate an alternative to the county's annual mowing-and-spraying of herbicide to control invasive species along the streambank.

Nature-Based Solutions Case Study Search
This database contains over 400 implementations of nature-based solutions. Use the filters to identify the case studies most relevant to you.
While all cases here exemplify applications of NBS strategies, they were gathered from various sources and not all were written using the framing of nature-based solutions. To qualify as a nature-based solution, a project must provide benefits to both people and nature. In some instances, the human benefits are present but not emphasized in the case write ups; these cases were included because they still provide useful information to learn from.

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.
In 2017, the Bedford Parks and Recreation Department partnered with Live Well Lawrence County to open Bedford Garden Park, a community garden. The resulting park is now a space that produces food, brings people together, and offers activities that improve physical and mental health.
To eradicate the Asian longhorned beetle (ALB), in 1999, USDA and USFS developed a 10-year plan in 1999 that follows five stages: phase-in, delimitation, and containment; suppression and control; deregulation; and eradication. All infested trees were either removed and replaced by non-ALB host trees on a one-to-one basis or treated with the insecticide Imidacloprid via trunk or soil injection.
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 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.
The City of Gary initiated the “Vacant to Vibrant” project in 2014, which aimed to mitigate flooding due to aging sewer system. The project completed the construction of three sites in the Aetna neighborhood by 2016, converting 0.37 acres of vacant land into green infrastructure featuring bat houses, rain gardens, and native plantings.
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.
The suburban city of Mount Rainer, Maryland aimed to restore the water quality Anacostia River, which was polluted by polluted stormwater runoff from urban and agricultural lands. The city developed Urban Green Infrastructure Plan to encourage community members to install nature-based stormwater control practices.
Since 2009, the Grand Teton National Park (GTNP) has been working to restore 4,500 acres of converted hay fields to their natural sagebrush conditions—conducting controlled experiments, initial restoration, and an adaptive management approach to achieve long-term, high quality ecological restoration goals.
Toledo, Ohio has experienced increased stormwater flooding and sewage system overflows, causing water quality issues and flood hazards. The city created the the Green Stormwater Infrastructure (GSI) Task Force to address these issues. One of GSI’s projects on Maywood Avenue used green infrastructure to improve water quality and reduce runoff.
The over 3-meter-high unstable banks of Meadowview stream were a serious public safety concern to the nearby community. To create a safer environment, the community installed a 3:1 slope planted with Californian native plants along the stream bank that was stabilized with compost rolls seeded with native grasses.
On August 4, 1984, the M/V Wellwood, a 122-meter Cypriot-registered freighter, ran aground on Molasses Reef about 6 nautical miles southeast of Key Largo in Monroe County, Florida. The Molasses Coral Reef Restoration Project, implemented by NOAA, involved the restoration of fourteen separate reef sites damaged during the 1984 incident.
To reduce the damage of future wildfires, the Paradise Recreation and Park District (PRPD) established multi-benefit greenspaces, or natural areas for recreational and aesthetic purposes (e.g. parks), within Paradise’s eastern and southern borders. These greenspaces will help increase community wellbeing and prevent trauma associated with wildfire by providing a multitude of recreational activities, conservation benefits, and local economic opportunity.
Northerly Island on Lake Michigan was used as a private airport until 2003, and sat unused and contributing no ecological or public benefits until 2012, when the U.S. Army Corps of Engineers proposed a restoration project. This project would restore 16 hectares into 6 habitats native to the Chicago area.
Ranch owners in the Alter Valley of Southern Arizona have worked with the US Natural Resource Conservation Service since 1984 to scientifically monitor range vegetation and conduct brush management to care for the 600,000 plus acre watershed surrounding the Ranch. Mechanical removal was conducted in 1984 – 1990 on 1,000 acres of shrubland.
Located at the intersection of North Plum Street and East Walnut Street, the site of numerous vehicle accidents from a confusing merge lane, the Plum and Walnut Green Intersection Project integrated green infrastructure (GI), enhanced pedestrian amenities and a roadway realignment to improve traffic safety and reduce stormwater runoff.
To restore the endangered Silvery Minnow, the Bureau of Reclamation, U.S. Fish and Wildlife Service, and the Save Our Bosque Task Force worked closely with a local landownerto restore approximately 0.8 river miles of critical habitat along the Rio Grande River. The project involved mechanical bank lowering and the creation of side channels and embayments.
In 2011, a 1,000-year flood caused deaths and over $2 billion in damage in Nashville, Tennessee. The city created a vibrant downtown park that incorporates flood protection measures. Riverfront Park includes a bioswale, bioretention areas, rainwater harvesting infrastructure, green roofs, and permeable pavers to reduce flood impacts.
Springhouse Run in Washington, D.C. is a tributary to the Anacostia River, which flows into the Chesapeake Bay. This project restored the stream and its riparian buffer to improve water quality, incorporate it aesthetically into the National Arboretum, reduce erosion, and enhance biodiversity.
