“…Landscape designers have the opportunity to contribute to the mitigation of the stormwater management problem, by incorporating these solutions in the design of residential gardens, corporate and institutional landscapes, and public green spaces, in order to combine aesthetic quality objectives with functional gains for the development of a more sustainable landscape [21].More recently [22], the term Blue-Green Infrastructure (BGI) has been used to define a planned network of natural and semi-natural areas that utilize natural processes to improve water quality and manage water quantity by restoring the hydrological function of the urban landscape and managing stormwater. In particular, bioretention structures are BGIs that mimic the hydrologic function of a natural landscape providing both flood control and water quality benefits [23].An experimental project was conducted in the Agripolis Campus of the University of Padova (Italy) in order to evaluate the efficiency in runoff reduction and water quality improvement of two bioretention solutions characterized by different scale and slightly different functions.One solution is a rain garden system, already investigated in other environmental conditions (e.g., [24][25][26][27][28][29][30][31][32][33][34][35][36]) but not in Italy, whose research results were recently published [37,38].The other solution is a new proposal, i.e., a bioretention pond (BP) with impervious walls to store and treat stormwater runoff as in floating treatment wetland (FTW) systems [39,40] with living ornamental plants. The BP is intended for green areas within blocks, mall centers, etc., to create a setting with aesthetic features and also able to intercept and retain stormwater runoff, reducing the peak discharge into the drainage system or main stream network, decreasing pollutants in the overflow water, and eventually working as a water reservoir for sustainable supplemental irrigation of beddings or other plant settings during drought periods.…”

With the purpose to study a solution based on Sustainable Urban Drainage Systems (SUDS) to reduce and treat stormwater runoff in urban areas, a bioretention pond (BP) was realized in the Agripolis campus of the University of Padova, Italy. The BP collected overflow water volumes of the rainwater drainage system of a 2270 m2 drainage area consisting almost entirely of impervious surfaces. Sixty-six Tech-IA® floating elements, supporting four plants each, were laid on the water surface. Eleven species of herbaceous perennial helophyte plants, with ornamental features, were used and tested. The early growth results of the BP functioning showed that nearly 50% of the total inflow water volume was stored or evapotranspirated, reducing the peak discharge on the urban drainage system. Among plants, Alisma parviflora, Caltha palustris, Iris ‘Black Gamecock’, Lysimachia punctata ‘Alexander’, Oenanthe javanica ‘Flamingo’, Mentha aquatica, Phalaris arundinacea ‘Picta’, and Typha laxmannii had the best survival and growth performances. A. parviflora and M. aquatica appeared interesting also for pollutant reduction in runoff water.

“…Green infrastructure practices can perform beyond their design capacity due to natural processes, such as infiltration and evapotranspiration (ET), that increase their potential for resilience and flood risk reduction [27][28][29][30]. Specifically, bioinfiltration practices have demonstrated an ability to capture runoff and reduce overflow events beyond the expected design performance [31,32].…”

Many communities throughout the world are utilizing green infrastructure practices to mitigate the projected impacts of climate change. While some areas of the world are anticipating droughts, other areas are preparing for an increased flood risk, due to changes in precipitation volume and intensity. Cities rely on practices such as bioinfiltration to sustainably capture stormwater runoff and provide resilience against climate change. As cities aim to increase resilience and decrease climate-change-associated risks, a greater understanding of these risks is needed. A risk-based approach was used to evaluate bioinfiltration design and performance. Climate projections from the Couple Model Intercomparison Project Phase 5 were used to create near-term (2020–2049) and long-term (2050–2079) climate datasets for Philadelphia, Pennsylvania, using two representative concentration pathways (RCPs 2.6 and 8.5). Both near-term and long-term climate models demonstrated increased precipitation and daily temperatures, similar to other areas in the U.S. Northeast, Midwest, Great Plains, and Alaska. Climate data were used to model bioinfiltration practices using continuous simulation hydrologic models. Overflow events and cumulative risk increased from bioinfiltration sites when compared to the baseline scenario (1970–1999). This study demonstrates how to apply a risk-based approach to bioinfiltration design using climate projections and provides recommendations to increase resilience in bioinfiltration design.

“…Rain gardens are a common form of GI, typically installed in private yards, and primarily designed to manage stormwater runoff (Jennings 2016). Their ability to retain a large portion of runoff inflows on a surfaces from 20 times their size has been established (Davis 2008;Davis et al 2012;Dietz and Clausen 2005;Hunt et al 2006;Kurtz 2008;Tang et al 2016;Zhang and Guo 2014).…”

A newly constructed rain garden in Shoelace Park in Bronx, New York, USA, was monitored between October 2014 and July 2015 as a pilot study aimed at testing the effectiveness of using urban park space to manage adjacent street runoff. Street inlet capture efficiency and rain garden retention were assessed through inflow and outflow monitoring and quantification. During the monitoring campaign consisting of 26 storms, the rain garden retained an average of 78% of all inflows, with full retention for storms under 10 mm (65% of monitored storms). New York City (NYC) is 72% impervious and 19.5% parkland in surface area. If only 4% of NYC parkland space were retrofitted with green infrastructure performing similarly to the Shoelace Park rain garden, the municipal goal of managing runoff from 10% of combined sewer-served impervious surfaces could be achieved, at least at the municipal scale. Additional spatial analyses are needed to determine whether potential parks are positioned ideally for stormwater capture given the variable conveyance capacities of the city's many combined sewersheds, and the desired pollutant load reductions for each of its receiving water bodies. As suitable right-of-way GI sites become rarer, parklands represent a new exciting opportunity for expanding the extent of distributed stormwater management in cities.
