After the Storm: How Green Infrastructure Can Effectively Manage Stormwater Runoff from Roads and Highways

Stormwater runoff from roads and highways pollutes and erodes our nation's water bodies, imposing health, financial, and environmental costs on local communities. These costs can be avoided or significantly reduced by ensuring that our roadways incorporate runoff controls that retain stormwater onsite. Green infrastructure, in particular, is an especially effective method for retaining stormwater that also generates a wide range of economic and social benefits beyond improved water quality. To ensure that these benefits are enjoyed by communities across the United States, legislative and administrative decision makers at the federal and state levels should provide incentives and requirements for these controls to be implemented at all road and highway facilities.
