Evaluation of Green Infrastructure as a Means to Mitigate Increased Stormwater Volumes in Disadvantaged Communities

Flooding in the United States, exacerbated by factors like increased urbanization and inadequate stormwater management systems, has grown in frequency and intensity, impacting both social and economic aspects. Extreme events, not limited to hurricanes and superstorms, have caused significant damage, as evidenced by a record-breaking rainfall event in St. Louis in 2022. The rise in flooding is attributed to urban development's expansion and impervious surfaces, leading to exponential stormwater runoff volumes that strain existing infrastructure. A potential solution to mitigate this issue is the adoption of green infrastructure, encompassing practices that mimic natural drainage systems like green spaces, trees, and vegetation. However, disadvantaged communities, often with high minority populations and poverty rates, remain inadequately shielded from flooding's environmental and public health repercussions, including pollutant mobilization and various health risks. As a result, there is a pressing need for improved evaluation and the implementation of green infrastructure, especially in areas affected by transportation-based flood events, to reduce the impact on these vulnerable communities. The research project will encompass a comprehensive approach which includes assessments of stormwater impacts on United States transportation corridors over the past decade and involves the evaluation of the frequency and intensity of these events. Additionally, the project aims to determine the level of urbanization in affected areas, investigate the socio-economic status of residents within these regions, appraise the existing green infrastructure status, and formulate recommendations for the implementation of green infrastructure solutions along transportation corridors to alleviate the adverse effects of stormwater on affected communities.
