Rain gardens are an established element of water sensitive urban infrastructure. However, information on people's preferences for such systems is lacking. To understand whether people express willingness to pay for such systems and whether estimates are transferable between locations, we conducted choice experiments in Sydney and Melbourne. We found that people are willing to pay for rain gardens. The marginal willingness to pay for different features is similar in both locations, but the transfer of compensating surplus values between locations still generates transfer errors. The implications of transfer errors are investigated using a benefit-cost analysis of a rain garden installation.

雨水花园是对水敏感的城市基础设施的既定要素。但是，缺乏有关人们对此类系统偏好的信息。为了了解人们是否表示愿意为这种系统付费，以及估计是否可以在不同地点之间转移，我们在悉尼和墨尔本进行了选择实验。我们发现人们愿意为雨水花园买单。在两个地点，支付不同特征的边际支付意愿相似，但是地点之间补偿性剩余价值的转移仍然会产生转移错误。使用雨花园设施的收益成本分析来研究转移误差的含义。
