Low Impact Stormwater Treatment Methods

In many places stormwater flows off highways into vegetated areas before entering surface or ground water. These areas include ditches, embankments, landscaping, medians, and even bioswales. Currently there is not adequate methodology to account for the treatment benefits these areas provide. This forces projects to address stormwater by constructing unnecessarily large BMPs, often in natural areas, resulting in high cost and further environmental degradation. Several states have recently completed or are nearing completion of studies on this subject intended to provide a basis for accounting for benefits. This project will both assess that work's applicability to Washington and tailor an approach for this state. It is anticipated that the project will attract partnership funds.
