Innovative Stormwater Treatment in Washington State

摘要

The Washington State Department of Transportation has earned a reputation as an innovative developer of large public works projects. Constructing and maintaining transportation facilities will always be the primary mission of WSDOT. However, the agency accepts responsibility for the potential environmental and social impacts of our facilities. A major responsibility is to protect our state's water quality and to preserve our environmental values. WSDOT has adopted the watershed-need philosophy as the best way to provide cost-effective water quality treatment. The Innovative BMP Research program will help provide clear selection criteria and design parameters for stormwater BMPs. This, in turn, will provide the best BMP for each project or outfall site. As the years go by, WSDOT anticipates a diminishing impact to watersheds from its transportation facilities.
