Municipalities, their utilities and resource managers are designing and implementing policies and programs toward climate adaptation, which means governing urban water resources differently. Urban water managers are thus expanding their roles and responsibilities through the installation and maintenance of green stormwater infrastructure (GSI) systems. This system expansion is perhaps more striking for water utilities administering GSI-related programs because they acquire a role that has an impact on how residents and neighborhoods will differentially experience the effects of climate change. Through an in-depth qualitative study of a GSI program in Tucson, Arizona, USA, we contribute to the socio-environmental justice framework with specific attention to distributive, procedural, recognition, interactional, and mobility justice. We highlight that a socio-environmental justice approach requires resource managers and decision-makers to recognize and respect the ways in which people’s everyday relationship to water and water infrastructure is impacted by culturally mediated social norms and values, as well as legacies of exclusion and inclusion in urban development and resource governance. Thus, we argue that discussions around water equity in urban water governance need to be placed within a socio-environmental justice framework to address historical inequalities and ensure these are not reproduced through GSI.
