Multi-functionality and Cost Analysis of Urban Blue-Green Infrastructure
As urban areas are expanding and densifying, applications of blue-green infrastructure (BGI) are proposed as a panacea for both social and environmental urban challenges. However, BGI includes a great diversity of individual subtypes. From hedges to streams, flowerbeds to green walls, urban forests to single street trees, each subtype comes with specific potential of improving environmental and social conditions. Whilst there is an ever-growing body of literature of the performance and planning of BGI subtypes for specific environmental or social benefits - for example, parks for recreation, and rain gardens for stormwater management – integrated approaches between subtypes and potential benefits are lacking. Thus, it is difficult for planners to compare how different BGI subtypes may provide solutions to the problems facing their local context. In an attempt to integrate the potential of BGI subtypes to provide heat stress reduction, stormwater management and recreation with the associated short- and long-term fiscal costs, a tentative cost-benefit analysis is presented. Different BGI subtypes potential for reducing heat stress, stormwater management and recreation in an urban Nordic context has been ranked based upon systematic literature reviews for each of the blue-green infrastructure subtypes. Moreover, the paper in which theses assessments will be published (currently under review) provides steps towards integrating the potential benefits frameworks with the costs of construction and maintenance – as the benefits can only be garnered if BGI elements are both constructed and maintained at the appropriate levels. Due to lack in the BGI literature concerning construction and maintenance costs, the costs were estimated by suitably qualified planners within the author’s local context. It is this integration between assessment of potential benefits with the estimated costs for construction and maintenance that brings novelty to the paper, as well as the combination of physical (stormwater management and heat ...
