Significant water pollution caused by flooding due to heavy precipitation and extreme weather events has become a considerable problem in urbanized areas such as in Northern New Jersey. These cities experience heavy downpour-related contamination and water pollution when stormwater and untreated sewage are diverted through combined sewer overflow drainage systems to adjacent water bodies. Green infrastructure has proven a successful intervention method for mitigating these unintended environmental consequences. However, while the effects of CSOs and the ability of GI to reduce them are well documented, there has been considerably less study addressing public preferences and willingness to pay for GI-based solutions. As such, this study seeks to understand these facets of GI management in urbanized areas of New Jersey, focusing on Newark, Paterson, and Elizabeth townships. A discrete choice experiment method was used to analyze the willingness of residents to pay for additional CSO infrastructure through the installation of GI options such as bioretention gardens, rain barrels, and green roofs. Furthermore, study identified attributes such as secondary benefits, proximity, and water retention that respondents found the most utility in when choosing GI stormwater management interventions. We found that several attributes, including improved air quality ($58.60), increased water supply ($49.71), and closer proximity ($110.01-$125.97) had the highest utility and similarly were associated with a higher willingness to pay than other tested attributes. These findings are important in assessing the overall attitude toward these fixtures, and may be critical in crafting local policy and development, especially to address environmental equity.
强降水和极端天气事件引发洪水，造成严重水污染，这在新泽西州北部等城市化地区已成为相当严重的问题。当雨水和未经处理的污水通过合流制下水道溢流排水系统排入相邻水体时，这些城市会遭受与暴雨相关的污染和水污染。绿色基础设施已被证明是减轻这些意外环境后果的成功干预方法。然而，虽然合流制下水道溢流的影响以及绿色基础设施减轻这些影响的能力已有充分记录，但针对公众偏好和为基于绿色基础设施的解决方案付费意愿的研究却少得多。因此，本研究旨在了解新泽西州城市化地区绿色基础设施管理的这些方面，重点关注纽瓦克、帕特森和伊丽莎白镇。采用离散选择实验方法分析居民通过安装生物滞留花园、雨水桶和绿色屋顶等绿色基础设施选项为额外的合流制下水道溢流基础设施付费的意愿。此外，研究确定了受访者在选择绿色基础设施雨水管理干预措施时认为最有用的属性，如附带效益、 proximity和保水能力。我们发现，包括改善空气质量（58.60美元）、增加供水（49.71美元）和更近的距离（110.01 - 125.97美元）等几个属性具有最高的效用，同样与比其他测试属性更高的付费意愿相关。这些发现对于评估对这些设施的总体态度很重要，并且在制定地方政策和发展规划方面可能至关重要，特别是在解决环境公平问题时。
