Scientific research and policy initiatives on using green infrastructure for pollution control are expanding. Potential cost-savings are often a prime motivation. However, environmental co-benefits may also ensue from such approaches. State of the science valuation methods, such as choice experiment surveys, are necessary to capture the full range and values of such benefits. We present a case study of this for the case of installing riparian shade corridors to meet temperature standards in an urban-rural fringe Oregon watershed. We use a primary survey, administered to a sample of 800 waste water treatment utility customers in the Tualatin river basin. Our findings shed light on the public’s willingness to pay (WTP) for the additional ecosystem services generated by this green infrastructure approach. Our estimates show significant WTP for water quality, air quality and preservation of fish and wildlife highlighting that the public values the additional benefits. We also find that the WTP for these ecosystem services is influenced by perceived water quality conditions as well as the respondent’s environmental attitudes. The results show that this green infrastructure program has substantial value beyond thermal pollution control. Indeed, by extrapolating the benefits to entire customer base suggests an attractive social benefit-cost ratio. This case analysis of a progressive ecosystem services management approach illuminates salient positive impacts of green infrastructure approaches beyond pollution control.
