“…There is strong support in both the International BMP Database , and our results that BMP type influences DIP removal performance. In the 2020 database summary, difference in median influent and effluent DIP concentrations was greatest for bioretention (leached 0.24 mg/L), followed by grass swales (0.07 mg/L), then grass strips (0.06 mg/L) . In our analysis, bioretention also leached the most on average (0.22 mg/L), although relative leaching from grass strips and swales was flipped compared to the Database report.…”

“…BMPs with vegetated soil ecosystem features were selected for their shared means of nutrient processing. These BMPs include bioretention, grass strips, and grass swales 11 (subsequently called vegetated BMPs). BMPs with less than three paired observations of influent and effluent were not considered.…”

Nutrient treatment performance of stormwater best management practices (BMPs) is highly variable. Improved nutrient management with BMPs requires a better understanding of factors that influence stormwater BMP treatment processes. We conducted a metaanalysis of vegetated BMPs in the International Stormwater BMP Database and compared influent and effluent nitrogen and phosphorus concentrations to quantify the BMP effect on nutrient management across climates. BMP effect on nutrient concentration change was compared between vegetated BMPs in wet and dry climates. We examined paired dissolved inorganic nitrogen (DIN), total nitrogen (TN), dissolved inorganic phosphorus (DIP), total phosphorus (TP), and combinations of these analytes as dissolved inorganic ratios and N:P ratios. Meta-analysis with subgroup analysis was used to determine differences between wet and dry climates and among vegetated BMP types. We found that across both wet and dry climates, BMPs leach DIP and TP, increase the fraction of dissolved inorganic P (DIP:TP), and decrease dissolved N:P ratios. Dry-climate BMPs leach DIP and TP more consistently and at a higher magnitude than wet-climate BMPs, and bioretention leaches more DIP than grass strips and swales. These findings generally align with biogeochemical cycling, differences in influent chemistry, and BMP design types and goals.

“…Furthermore, the lack or inadequacy of GSI performance data, especially those collected through on‐site monitoring, for a site‐specific climate and watershed, is highlighted in many studies (Cohen‐Shacham et al, 2019; Deely et al, 2020; Dhakal & Chevalier, 2017; Hamel & Tan, 2021; Kumar et al, 2020). This might be partially due to the fact that, even with all the significant progress in stormwater‐related performance monitoring manifested in commonly‐used databases, the extrapolation and generalization of a case study‐specific data to other projects or even larger spatial scales leads to uncertainty in performance assessment for GSI planning and performance estimation and even misconceptions about their features and functionality (Clary et al, 2020; Shafique & Kim, 2017; Ureta et al, 2021).…”

Rapid urbanization, aging infrastructure, and climate change impacts have put a strain on existing stormwater drainage systems. One commonly acknowledged solution to relieve such stress is Green Stormwater Infrastructure (GSI). Interest in GSI technology has been growing. However, the level of implementation in many areas around the world lags behind the interest level. This study aims to critically review the body of literature from the last decade to determine the main barriers to wide adoption and the offered solutions to overcome them. Based on a review of 92 peer-reviewed journal articles published between 2012 and 2022, we classify barriers and solutions into six categories: socio-cultural, financial, institutional and governance, legislative and regulatory, technical, and biophysical. Based on observations and conclusions from the reviewed articles, we recommend the following pillars and considerations for more GSI adoption: increasing awareness and outreach programs; enhancing knowledge and data co-production and dissemination; acknowledging interdependency and context-specificity of many of the challenges and solutions; prioritizing integrated and participatory watershed planning; overcoming institutional path-dependencies; prioritizing innovative solutions; giving specific consideration to maintenance protocols; considering the role of public entities; and actively engaging with communities.

“…A suite of structural controls, called stormwater best management practices (BMPs), are available to Meter and Basu 2015; Pitt et al 2018). Similarly, factors that vary with region such as air temperature, BMP design, and inflow concentrations have been shown to regulate BMP performance (Barrett 2008;Rosenzweig et al 2011;Mallin et al 2012;Granato 2014;Koch et al 2014;Bell, Tague, et al 2017;Clary et al 2017;Mcphillips and Matsler 2018). Because these controls on performance vary with region, we hypothesize that BMP performance also varies regionally.…”
