Arden Park is along Minnehaha Creek, an impaired waterway that is a tributary to the Mississippi River. This park is in a highly developed suburb just south of Minneapolis (Edina). This project improved the park and restored a section of the creek, improving habitat, water quality, and recreation opportunities.

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.

Buffalo Slough Island in Sturgeon Lake is home to important cultural resources for the Prairie Island Indian Community (PIIC). The island was experiencing erosion and habitat loss, until the U.S. Army Corps of Engineers and the PIIC signed a project partnership agreement to restore the island.
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.
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.
The National Park Service led an oak savanna restoration project along a 5-acre stretch of the Mississippi River Gorge in a Minneapolis neighborhood. The project sought to eliminate the threat of exotic species, reintroduce the appropriate gorge plant community, and address erosion concerns with the collaborative effort of national and local agencies, and the advocacy of the local community.
Pool 8 is a degraded 15,400-hectare area in the Upper Mississippi River System. To restore aquatic and terrestrial habitat, the U.S. Army Corps of Engineers used dredged sediment to reconstruct islands in Pool 8. This reduced erosion, improved water quality and clarity, and allowed for habitat restoration.
The Nature Conservancy conducted research in the Saz-Zim Bog with the mission to measure carbon and methane emissions from the bog in order to learn more about its potential for mitigating climate change and the best approach for restoration. Long misunderstood and unappreciated, peatlands are gaining recognition for the carbon storage and other ecosystem benefits they provide.
Spring Peeper Meadow Wetlands Restoration Project (SPM) aimed to restore a 30-acre sedge meadow on a tiled cornfield. Invasive reed canary grass was eliminated in 1995, and 115 species of native wildflowers, grasses, and sedges were planted to restore the original plant community. Over 67,000 seedlings and transplants were systematically planted.
The Sugarloaf Cove site, historically a rare wetland on the north shore of Lake Superior, was used as a landing site for a pulpwood operation and was leveled and filled with gravel to build roads and buildings. Minnesota Department of Natural Resources led a restoration project in 1998 to excavate gravel and plant native plants onsite.
In 2017, the City of St. Louis Park, Minnesota implemented the Rainwater Rewards Program with the goal of increasing awareness and importance of managing stormwater and green infrastructure throughout the city. The program seeks to increase green infrastructure by providing residents with financial and technical assistance to install projects that reduce stormwater runoff on residential properties.
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.
