“…In keeping with the requirements for the UBGI development [8,17,59], six variables are selected to assess land suitability, including policy-related [56,60] and physical factors [61]. The variables were classified into two categories: (1) potential land acquisition (PLA), which describes the potential for acquiring land for UBGI development based on planning policy and the land's existing condition [32,42]; and (2) feasibility in installation (FII), which outlines suitability at the physical, ecological, and construction levels [62,63].…”

“…Although the components of UBI and UGI are totally different, it has become evident that their services and spatial layouts may be correlated and that they can complement each other [6]. Consequently, recent research increasingly considers UBI and UGI as an integrated system and explores their combined environmental and public services [7,8].…”

“…Recognized as an effective tool to improve environmental performance at the urban scale, urban blue and green infrastructure (UBGI) plays an increasingly critical role in managing stormwater, improving ecological connections, and mitigating urban heat island effects, among other issues [2,8]. For example, synergy in the layouts of UBI and UGI can take full advantage of the benefits of both green and blue technologies and services [6,9].…”

“…Integrating blue and green systems, whose different features would probably have been organized in isolation in the past, is challenging. Adapting UBGI to the built environment is itself a task full of complexity and uncertainty [8,30]. For example, in the existing urban context, highly mixed land uses, populations, and facilities would raise diverse demands for UBGI development that would have to be distributed in different patterns with different intensities [19].…”

Urban blue infrastructure (UBI) and urban green infrastructure (UGI) can be seen as an integrated system in which services and spatial layouts complement each other. However, given its complexity, it is difficult to integrate and optimize the layout of urban blue and green infrastructure (UBGI) in the built environment. This study develops a planning support tool for the layout integral optimization (PSTLIO) of UBGI. Using Hekou City in China as a case study, service demands and the supply of suitable land for UBGI development are assessed and mapped on geographic information system (GIS). The potential areas for UBGI development are delineated after mapping assessments of service demand and land supply and suitability. Following discussions on the exact means for PSTLIO to support the layout optimization of UBGI, a PSTLIO-based solution is developed to structure the UBGI link network and hub system, define the functions and service patterns of single UBGI components, and provide guidance for determining the scale of UBGI components. The results show that PSTLIO is able to provide a quantifiable base for decision-making in UBGI layout optimization.Sustainability 2020, 12, 1613 2 of 22 solution, UBGI could also provide an abundant base for urban ecosystems, in which diverse ecologies and networks could be conserved [12,13]. Moreover, the effects of UBGI in regulating the urban microclimate were also explored in recent studies [14]. It was proven that UBGI could cool urban areas through evapotranspiration, shadowing, adjusting emissivity, and affecting air movement and heat exchange [3,15], indicating UBGI's huge potential in relieving the urban heat island effect (UHIE) [16].UBGI offers opportunities to significantly improve urban public services [17][18][19][20], facilitate social connections, and enhance the quality of public spaces [21,22]. UBGI can boost vitality and increase surrounding land values. It can, thus, be employed as a catalyst for redevelopment [23][24][25]. Furthermore, the potential benefits of UBGI in terms of aesthetics and spatial definition could also be effectively deployed to preserve and reshape the identity of a site or even a city, especially in the case of key locations such as municipal centers or historic areas [26,27].Due to UBGI's various benefits, investigations into the integral planning and management of UBGI are currently being carried out all over the world. As a result, a series of interchangeable terms have emerged, including water-sensitive urban design (WSUD) and sustainable urban drainage systems (SUDS) in the UK and Australia, as well as low-impact development (LID) [28] and stormwater best management practices (SBMP) [29] in the United States.However, in practice, formulating an integral plan for UBGI can be difficult. Integrating blue and green systems, whose different features would probably have been organized in isolation in the past, is challenging. Adapting UBGI to the built environment is itself a task full of complexity and uncertainty [8,30]. For example, in t...

“…At the local scale, the idea of multifunctionality has been rapidly adopted by the urban drainage research community (Fletcher et al, 2015), and has resulted in a fast growing range of innovative multifunctional solutions for flood management that provide various benefits across multipurpose designs (Lawson et al, 2014;Morgan & Fenner, 2017;Zareba, 2014). These designs are often referred to as sustainable urban drainage systems (SUDSs), water sensitive urban designs (WSUDs), or simply blue-green infrastructure (BGI) (Fletcher et al, 2015;Ghofrani, Sposito, & Faggian, 2017;O'Donnell, Thorne, & Yeakley, 2018). For example, with multifunctional BGI (e.g., bioswales, retention ponds, rain gardens, green roofs), opportunities are created to extend the benefits of the designs beyond flood management (Demuzere et al, 2014;Jha et al, 2012;Morgan & Fenner, 2017;Peng & Jim, 2015).…”

Urban flood management is increasingly expected to be multifunctional to integrate with the existing functioning of cities. Locally, this led to the development of sustainable urban water drainage designs, while at larger scales, blue‐green or water‐sensitive cities are considered as examples for how cities should function. Upscaling local designs to city‐scale flood resilience is not straightforward, however, due to the complexity of physical infrastructure and socio‐economic interactions within urban systems and requires “system‐of‐systems” thinking. To this end, we introduce the concept “interoperability” to guide transition from local multifunctionality to city‐scale multisystem flood management, through actively managing connections between infrastructure systems to convey, divert, and store flood water. While flood management is already based on these connections, interoperability is about explicitly emphasising them to explore and create opportunities to facilitate the integration of systems for flood management. The main research need arising from this conceptualisation is to determine how spatial data on infrastructure, environment, and social characteristics in urban areas can serve as a basis to identify opportunities and barriers for interoperability. By introducing interoperability and the research needs arising from it, a framework is created to facilitate and encourage practical thinking and discussion about system integration in urban flood management.

Co‐benefits and conflicts in alternative stormwater planning: Blue versus green infrastructure?

Blue-green infrastructure (BGI) is often promoted for its co-benefits and multifunctionality. However, this infrastructure is repeatedly planned, implemented and researched almost entirely based on the goals of stormwater management. Thus, more knowledge is required about how co-benefits are perceived and actioned by planning actors. By investigating co-benefits from a value perspective, this paper will contribute to the ongoing debate on how stormwater planning actors address the potential co-benefits and conflicts in the planning and implementation of BGI. The data are derived from policy document analyses and interviews with municipal and private planning actors in Bergen and Tromsø, Norway. The paper argues that municipal water actors are motivated to implement BGI beyond stormwater management goals and approach co-benefits and holistic stormwater management as an ideal in stormwater planning. However, the tensions and conflicts between the co-benefits become more evident in the actual implementation of BGI. The paper finds that when holistic BGI implementation is initiated by the municipal water actors, the stormwater management aspects dominate the BGI implementation. Finally, the paper concludes that even though blue and green values and interests are often conflicted in the implementation of BGI, urban stormwater planning is in the process of developing a blue-green value set based on the potential synergies of co-benefits. The paper therefore empirically illustrates how collective values and interests can develop and unfold across sectors and professional disciplines in BGI planning.
