Abstract: This study evaluates the public benefits associated with different green roof systems to manage stormwater runoff in Milwaukee, Wisconsin. An internet-based stated-preference conjoint choice experiment was administered to residents of Milwaukee to ascertain the public benefits value of different potential green roof infrastructure programs. This study contributes to the literature on the public benefits of green roofs in two ways. First, this study examined the perceived value of dynamic stormwater retention facilitated using “smart” green roofs with access to real-time weather data versus traditional extensive green roofs. Second, a wider range of public benefits associated with green roofs, including improved water quality, air quality, biodiversity, and urban heat island effects, were estimated. Estimation of these public benefits allows for determination of the optimal public policy for supporting green roofs as a component of decentralized stormwater management in municipalities.
