According to the US EPA, Green infrastructure is a “cost-effective, resilient approach to managing wet weather impacts that provides many community benefits. While single-purpose gray stormwater infrastructure—conventional piped drainage and water treatment systems—is designed to move urban stormwater away from the built environment, green infrastructure reduces and treats stormwater at its source while delivering environmental, social, and economic benefits.” Examples of green infrastructure include rain gardens, bioswales, trees, permeable pavements, and much more.
To estimate the percentage of land in Cleveland classified as green infrastructure, the following was added together:
- Green space in Cleveland parks;
- Tree Canopy (outside of the park system); and
- Green infrastructure projects funded by the Northeast Ohio Regional Sewer District.
