“…It should, therefore, be of use for further investigations as well as development of BGI management practices. The study is also relevant for understanding short-term and long-term environmental effects [13] and may be of value for improving the public perception of these valuable engineered assets [14].…”

Stormwater retention ponds are an important part of blue-green infrastructure, providing multiple benefits associated with flood resilience, water quality improvements, wildlife habitat creation and increases in amenity and biodiversity values. Here we compare two ponds in Edinburgh (Scotland): Oxgangs and Juniper Green. These were both established 10-15 years ago during construction of housing estates and are 3.5 km apart. The volumes of the ponds were calculated using detailed hydrographic data (obtained as part of this study). Delineation of catchments was performed using fine resolution DEM data together with details of the storm water sewer network. Hydrological and hydrodynamic modelling was carried out using the SHETRAN and CityCAT models. The presence of the ponds not only delays peak discharge after an extreme precipitation event but also reduces it rather considerably. Reductions in peak discharge and delay are much bigger for the larger Oxgangs pond, giving a 45% reduction in discharge and a 5-minute delay for a 15-minute one-in-100-year event. Data obtained on water chemistry, abundance of planktonic organisms and abundance of macroinvertebrates suggest that the increase in pollutant levels affects biological water quality and the ecosystem structure. Oxgangs pond has much higher electrical conductivity, corresponding to higher concentrations of specific elements and lower macroinvertebrate indices than Juniper Green. However, the water in Juniper Green is enriched in Ag, Pb and a number of REE, which may be related to discarded electronics. In addition to the flood resilience and water quality benefits, both ponds provide considerable amenity and biodiversity value. To date, there are 103 and 22 species of vascular plants, 20 and 16 species of bryophytes, 5 and 2 species of non-lichenised fungi and 11 and 4 species of epiphytic lichens recorded, respectively, at Oxgangs and Juniper Green. The results presented here have implications for further research and stormwater pond design and management practices.

“…Whereas, the lowest scoring criteria tend to reflect newer policy areas such as public access to SuDs; maintenance specifications for GI components and early discussions with stakeholders; areas where local authorities often lack the necessary experience or confidence to raise with developers (Hislop & Corbett, 2018). Significantly, there are wider research gaps evident in literature over integrated water management and SuDS (Williams et al, 2019) and financing mechanisms for GI (Scott, Holzinger and Sadler, 2017) which hinder policy further here. This also is exacerbated by the impact of austerity on the planning resources within local authorities which can restrict the extent to which GI multi-functionality can be embedded in policy and/or achieved on the ground (Gray & Barford, 2018).…”

This paper develops and tests a new self-assessment policy tool that illuminates the quality of planning policy for green infrastructure (GI). Working with 19 local planning authorities within the UK Central Scotland Green Network area (CSGN), the multi-functional coverage and strength of GI policies in statutory development plans were assessed. The tool was built from fusing two existing but unrelated initiatives addressing GI standards; Building with Nature and Integrating Green Infrastructure (IGI). The results reveal surprising variation across the functional coverage of GI-related policy and strength of associated policy wording, suggesting a significant vulnerability for how GI is mainstreamed in decision-making processes. To address this knowledge exchange deficit, the best performing policies were captured and adapted to inform a suite of model policies with global application. Significantly, the policies champion the different functions performed by GI and stress the need for early and ongoing involvement throughout any development process with funding for long-term stewardship post-development. The results serve as a catalyst for improved dialogue and social learning across planning, and wider built/natural environment teams and professions to plug identified policy gaps. In particular, there is recognition of the need for planning policy responses to move outside their usual environmental remit and engage with other policy sectors using more holistic policy hooks such as placemaking, placekeeping and the climate emergency. We argue that this tool has universal applicability in many planning systems for improving the policy response and imperative for GI, thereby increasing the potential for better spatial planning delivery.

“…Residents' attitudes towards the implementation of stormwater infrastructures in public spaces involve not only individual attitudes but also their trust in institutions and some governance and institutional factors, such as their level of involvement in the decision-making process, the system of incentives (see [9,33] for a review), management of maintenance costs and impact in terms of joint provision of a wide set of ecosystem services (e.g., thermal comfort, social and aesthetic values), positively impacting on the housing market [34] and/or residents' wellbeing [35,36]. Everett and Lamond [37] and Lamond and Everett [38] framed all these factors in a Social Practice model.…”

“…Finally, residents' attitudes toward the implementation of GreenSIs is also driven by their appreciation of the wide set of GreenSIs-related ecosystem services (e.g., air quality, aesthetics) that are lacking in the GreySIs. However, it is worth noting that most people rate the flood protection functional value at the highest level among GreenSI-related ecosystem services [34,35].…”

As a consequence of climate change, the impact of pluvial flooding is expected to increase in the next decades. Despite citizens’ poor knowledge, several types of stormwater infrastructure can be implemented to mitigate the impact of future events. This paper focuses on the implementation of green and grey stormwater interventions (i.e., with or without vegetation) on private properties. Framed by the Protection Motivation Theory, a survey-based case study analysis, carried out in a pluvial flooding-prone area of the Veneto Region (Italy), highlights the main factors driving people’s willingness to implement these interventions. The analysis shows that the implementation of grey stormwater infrastructures is driven by the perceived threat and the amount of past pluvial flooding damage (i.e., the direct experience as a proxy of prior knowledge) while the implementation of green stormwater infrastructures is driven also by additional factors (awareness of these interventions, age and education level of the citizens). Based on these results, lack of knowledge on innovative stormwater interventions represents a critical barrier to their implementation on private properties, and it confirms the need for specific dissemination and information activities.
