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.

The Paseo de las Iglesias restoration project aims to reverse severe environmental degradation and improve flood resilience along the Santa Cruz River. The project’s main goals are: significant ecosystem revitalization, on-site water reclamation and storage, hybrid green/gray erosion control, historic programming, and public access and recreation.  

State/Territory:

Urban development caused poor water quality, a falling water table, and erosion in the Sante Fe River. The city and county of Santa Fe and the Santa Fe Watershed Association are integrating river restoration with green infrastructure projects and public recreation opportunities to improve water quality, riverine habitat and mitigate flood risk.  

State/Territory:

The EPA, FEMA, and Rebuild Iowa partnered to plan economic growth and redevelopment of the Iowa City riverfront following the devastation of the 2008 Iowa floods. The primarily goal of the partnership was to add green infrastructure and add open space along the riverfront to reduce future flooding.

State/Territory:

This project reconnected 965 acres of Columbia River floodplain to the lands and waters of the Steigerwald Lake National Fish and Wildlife Refuge. This reconnection reduces flood risk, improves terrestrial and aquatic wildlife habitat, and restores natural ecosystem functions. This project protects nearby communities from flooding that have consistently damaged properties. 

State/Territory:

Teaneck Creek Park is a low-lying area in a highly urbanized neighborhood of North New Jersey. During storm and rain events, this area experienced flooding, erosion, and produced untreated runoff that degraded Teaneck Creek. This project restored 8 hectares of wetland habitat to mitigate these negative outcomes. 

State/Territory:

Napa County has experienced flash floods that resulted in deaths and hundreds of millions of dollars in damages. Napa and surrounding counties opted for a restorative flood mitigation approach to address environmental issues while increasing flood resiliency. The project design aimed to return the river to its natural state to prevent flooding. 

State/Territory:

The highly urbanized Rahway River watershed in New Jersey suffers from frequent flooding due to extensive development and destruction of riparian wetlands and floodplains. A diverse group of stakeholders worked together to restore a 1.8 ha site on the floodplain to riparian wetland.

State/Territory:

The Trinity River is a channelized and levee-managed river that runs through downtown Dallas, Texas. The river has contributed to major flooding events in the city, and the U.S. Army Corps of Engineers created the Chain of Wetlands plan to improve infrastructure and reduce flooding risk. 

State/Territory:

Tulalip Tribe and other tribes in the Snohomish basin are concerned by the decline in salmon population in the region. Salmon loss is considered an economic, cultural, and spiritual threat to the tribal members’ lifeblood and identities. Local groups worked with farmers to control agricultural runoff that was found to be the major cause of salmon mortality.

State/Territory:

Following a 100-year rain storm in 1999, city officials of Two Harbors, Minnesota were concerned by the devastating flood damages to infrastructure, properties, roads, and water ways. They designed stormwater management plan emphasizing green infrastructure development. All togather, the city built three flood control basins, two streambank stabilization projects, and a rain garden.

State/Territory:

The Chesterfield Heights neighborhood of Norfolk, Virginia is experiencing increased stormwater flooding and rapid sea-level rise. To address increased flooding, the goals were to conduct an adaption design process with full community involvement that focused on adaptation before significant storm and flooding damage occurred, and to maintain or expand ecosystem services. 

State/Territory:

Watergate Wetlands Restoration Project aimed to restore wetlands that were historically present at Delaware Water Gap National Recreation Area, and to restore the natural function of Van Campens Brook. Led by the National Park Service, the project involved draining constructed ponds and pumping water back into the brook through a sediment-blocking filter.
