*Review* **Social Barriers and the Hiatus from Successful Green Stormwater Infrastructure Implementation across the US**

**Jingyi Qi 1,\* and Nicole Barclay 2**


**Abstract:** Green stormwater infrastructure (GSI), a nature-inspired, engineered stormwater managemen<sup>t</sup> approach, has been increasingly implemented and studied especially over the last two decades. Though recent studies have elucidated the social benefits of GSI implementation in addition to its environmental and economic benefits, the social factors that influence its implementation remain under-explored thus, there remains a need to understand social barriers on decisions for GSI. This review draws interdisciplinary research attention to the connections between such social barriers and the potentially underlying cognitive biases that can influence rational decision making. Subsequently, this study reviewed the agent-based modeling (ABM) approach in decision support for promoting innovative strategies in water managemen<sup>t</sup> for long-term resilience at an individual level. It is suggested that a collaborative and simultaneous effort in governance transitioning, public engagement, and adequate considerations of demographic constraints are crucial to successful GSI acceptance and implementation in the US.
