Green stormwater infrastructure mirrors natural hydrologic processes and is presented as an alternative or complement to traditional gray stormwater infrastructure, which uses concrete channels and pipes to convey flows away from neighborhoods. To encourage green infrastructure installation, practitioners promote co-benefits, also called ancillary...

As we move into an era of increased urbanization, stormwater practitioners are charged with creating multibenefit solutions through the installation of stormwater control measures (SCMs). Two drivers facilitate the accrual of benefits in SCMs: hydrologic or water quality process and vegetation. This study investigated the feasibility of incorporati...

Urban greening practices are often adopted to mitigate the negative impacts of increasing impervious surfaces in urban areas. In the United States, green approaches are prevalent in the field of stormwater management as some cities are required to install green stormwater infrastructure (GSI) to meet regulatory requirements. While the primary funct...

Prioritizing stormwater infrastructure projects is challenging. In addition to regulating runoff and complying with water quality standards, agencies also consider factors such as life cycle costs, environmental impacts, and cobenefits to the environment and community. This work reviews literature on these decision-making criteria for stormwater pr...

The objective of this research is to develop of a planning-level, site scale integrated decision support tool (site scale i-DST) for grey and green stormwater infrastructure. The site scale i-DST has several component modules integrated into a single tool. The component modules include runoff estimation module, water quality module, BMP cost module...
