“…The efficiency and longevity of GSI can be directly linked to GSI maintenance and care, which increases the need for greater maintenance research and planning. Without regular upkeep, many GSI sites develop issues, such as clogging and sedimentation, which could prevent proper stormwater capture (Holt, 2021;Smith et al, 2021). Previously, studies have started to show the importance of maintenance by observing these common clogging mechanisms like litter, sediment, and vegetative debris (Hunt, Lord, and Smith 2005;Seattle Public Utilities 2009;Homet et al, 2022).…”

Green stormwater infrastructure (GSI) is an increasingly popular tool to meet federal water regulations for stormwater quality and quantity, while assuaging urban flooding. While cities across the United States implement GSI into their planning processes, they are also potentially affecting the local communities that are receiving these GSI through social, ecological, physical, and economic impacts. Flooding is impacting urban communities by damaging homes and infrastructure, degrading ecosystems, and exacerbating social inequities. In the planning process, there is an acute need for the consideration of the equitable distribution of GSI in addition to technical and engineering needs. This study examines multiple aspects of vulnerability to local flooding impacts—social, environmental, and infrastructural—across a city landscape to identify those communities that have a greater need for GSI. Given the city of Philadelphia is a leader in GSI implementation in the United States, we use it as our research setting where we create citywide, multifaceted vulnerability indices that account for the spatial distribution of social, built environment, and maintenance vulnerabilities to flooding events. In addition to these indices, a GSI type decision table was created to suggest more equitable placements of different GSI types based on their maintenance needs and expected co-benefits. The results of this study reveal unequal distribution of social and built-environment vulnerabilities in the city at the Census block group scale, with high social vulnerability consistently spread across the central, southwest, and northwest neighborhoods of Philadelphia. Potential areas of severe GSI maintenance impacts appear to be concentrated in the downtown neighborhoods, while overall vulnerability appears elevated throughout the downtown and northwest neighborhoods. These results indicate that some communities in Philadelphia are highly vulnerable and should be prioritized for GSI implementation. In addition, the type of GSI implemented should be optimized to address the specific vulnerability impacts in different areas. A multifaceted vulnerability approach to planning can be applied in multiple areas of climate adaptation equity, with future studies continuing to update and add more dimensions of vulnerability where and when applicable.

“…Dynamic GSI systems and performance data, along with data tools and technologies, can enhance operational decisions and cost-effectiveness of maintenance activities (Wadzuk et al 2021). Within the municipal stormwater management community, there is a desire for improved data management and communication.…”

“…Municipalities that have embraced green stormwater infrastructure (GSI) as a stormwater management approach are discovering that streamlining the maintenance of these systems is needed to sustain performance at a reasonable cost. The need to rethink and refine GSI maintenance was called out in Wadzuk et al (2021); several recent publications also highlighted the need for maintenance, and offered suggestions for how to perform GSI maintenance (Houle et al 2013;Blecken et al 2017;ASCE 2018;Clary et al 2018;DelGrosso et al 2019). Wadzuk et al (2021) recommends specific focus on improving maintenance approaches using data and risk to make informed and financially viable decisions about GSI maintenance for the community.…”

Having an affordable and robust maintenance program is the key to ensuring long-term functionality of GSI and the broader protection of the watershed.…”

“…The core concept behind a data-driven maintenance framework is that it should be an adaptive approach (Wadzuk et al 2021) that can adjust as new and more data are obtained, the quality of data improves, and the support technology advances. This approach opens the door for more efficient and directed GSI maintenance in the ever-changing urban environment.…”
