Urban stormwater management using green infrastructure: challenges and solutions to enhance long-term performance and stakeholder acceptance

Abstract

Green stormwater infrastructure (GSI) is implemented to mitigate the impacts of urbanization and climate change, including flooding, water pollution, water scarcity, and the urban heat island effect. However, many installations fail to function effectively, and the underlying causes remain poorly quantified, partly due to limited knowledge of how GSI success and failure are evaluated in practice. This study addresses this gap through a survey of 43 municipal managers and semi-structured interviews with 14 managers across Australia, Canada, the UK, and the USA. Results indicate that GSI success and failure are multi-dimensional and extend beyond technical performance metrics. GSI projects wer..
