Transforming US urban green infrastructure planning to address equity

Abstract

Cities across the Unites States have embraced green infrastructure (GI) in official planning efforts. The plans conceptualize GI as providing multiple functions and benefits for urban residents, and form part of complex responses to intersectional urban challenges of social injustice and inequity, climate change, aging and expensive infrastructure, and socio-economic change. To date, it is unclear whether official city GI programs address systemic racism and urban inequality.To fill this knowledge gap, we coded and analyzed 122 formal plans from 20 US cities to examine if and how they address equity and justice in three domains: visions, processes, and distributions. We find a widespread failure of plans to conceptualize and operationalize equity planning principles. Only 13% of plans define equity or justice. Only 30% of cities recognize that they are on Native land. Over 90% of plans do not utilize inclusive processes to plan, design, implement, or evaluate GI, and so target many communities for green improvements without their consent. Although 80% of plans use GI to manage hazards and provide multiple benefits with GI, less than 10% identify the causes of uneven distributions and vulnerability. Even fewer recognize related issues of houselessness and gentrification. Very few plans have mechanisms to build community wealth through new GI jobs. We find promising seeds of best practices in some cities and plan types, but no plan exemplified best practices across all equity dimensions. If formal GI planning in US cities does not explicitly and comprehensively address equity concerns, it may reproduce the inequalities that GI is meant to alleviate. Based on our results, we identify-three key needs to improve current GI planning practices for green infrastructure and equity. First, clear definitions of equity and justice are needed, second, planning must engage with causes of inequality and displacement, and third, urban GI planning needs to be transformed through a focus on inclusion.
