The District of Columbia Water and Sewer Authority (DC Water), in an effort to reduce combined sewer overflows (CSOs), is implementing green stormwater infrastructure projects to reduce runoff. These projects include rain barrels, grassed swales, cisterns infiltration trenches, permeable pavements, increased tree cover, and rooftop greening.

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 Kenilworth Marsh tidal wetland restoration project, led by the National Park Service, aimed to restore areas in Washington, D.C. that were degraded from altered hydrology and contamination. The project team placed 130,000 cubic yards of dredged material to restore hydraulic function of the tidal marshes, installed over 350,000 native plants, and removed invasive purple loosestrife and phragmites.

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.
