“…Urban trees can treat stormwater through evapotranspiration [104] and also provide species and recreational habitat [44] while cooling urban areas in subtropical climates [105,119]. Stormwater ponds provide temporary flood storage [124], pollutant removal on the basis of particle settling [136] and denitrification [75,[137][138][139], and biodiversity and recreational opportunities [14,140]. Filtration practices are frequent components of GSI where surface land area is limited and can remove specific dissolved pollutants from runoff, such as phosphate [58,63,[167][168][169][170].…”

“…During this time, suspended solids and particle-associated pollutants, including phosphorus, can settle to the bottom of the ponds. Performance expectations are based on the incoming pollutant load, permanent pool volume, and retention of sediment [136]. Often, stormwater ponds are also expected to remove nitrogen through sedimentation and denitrification [75,[137][138][139].…”

“…When ponds are maintained, the conventional approach is sediment dredging. The accumulation of organic pollutants (such as polycyclic aromatic hydrocarbons, PAHs [136,151]), heavy metals, and other toxins, however, can cause dredged sediments to be regarded as hazardous waste [72]. This results in higher transport and disposal costs, often making pond maintenance prohibitively expensive.…”

“…Nevertheless, steps can be taken to make green roofs viable stormwater treatment practices as well. Nutrient-rich stormwater draining from green roofs can be routed to easily mown grass filter strips [136] by disconnecting downspouts from storm drains [180,181], harvesting rainwater for reuse [242], or even implementing secondary GSI practices like rain gardens. Where these options are not viable, the effluent could be treated directly using various methods [214,234].…”

“…It is now possible to supplement traditional inspections with remote sensors collecting real-time data on key performance indicators as well as inexpensive video recording [252] and even drones [253]. Traditionally, most monitoring and sampling is done on sunny days during the warm season, but GSI performance varies seasonally as does pollutant loading (for example, nutrients trapped in snow and released during snowmelt while plants are still dormant and the soil may be frozen [136]). In addition to enabling high-frequency and continuous monitoring, low-cost, DIY (do-it-yourself) systems introduce the opportunity for adaptive or even active management to improve GSI functionality but also introduce a new level of concerns ranging from electrical failures to cyber security [254].…”

Green infrastructure designed to address urban drainage and water quality issues is often deployed without full knowledge of potential unintended social, ecological, and human health consequences. Though understood in their respective fields of study, these diverse impacts are seldom discussed together in a format understood by a broader audience. This paper takes a first step in addressing that gap by exploring tradeoffs associated with green infrastructure practices that manage urban stormwater including urban trees, stormwater ponds, filtration, infiltration, rain gardens, and green roofs. Each green infrastructure practice type performs best under specific conditions and when targeting specific goals, but regular inspections, maintenance, and monitoring are necessary for any green stormwater infrastructure (GSI) practice to succeed. We review how each of the above practices is intended to function and how they could malfunction in order to improve how green stormwater infrastructure is designed, constructed, monitored, and maintained. Our proposed decision-making framework, using both biophysical (biological and physical) science and social science, could lead to GSI projects that are effective, cost efficient, and just.

This review summarizes over 280 studies published in 2019 related to the characterization, control, and management of urban stormwater runoff. A summary of quantity and quality concerns is provided in the first section of the review, serving as the foundation for the following sections which focus on the control and treatment of stormwater runoff. Finally, the impact of stormwater control devices at the watershed scale is discussed. Each section provides a self-contained overview of the 2019 literature, common themes, and future work. Several themes emerged from the 2019 literature including exploration of substrate amendments for improved water quality effluent from stormwater controls, the continued study of the role of vegetation in green infrastructure practices, and a call to action for the development of new models which generate reliable, computationally efficient results under the physical, chemical, biological, and social complexity of stormwater management. © 2020 Water Environment Federation • Practitioner points • Over 280 studies were published in 2019 related to the characterization, control, and treatment of urban stormwater. • Studies on bioretention and general stormwater characteristics represented the two most common subtopics in 2019. • Trends in 2019 included novel substrate amendments, studies on the role of vegetation, and advancements in computational models.
