Socially Vulnerable Communities and Green Stormwater Infrastructure planning in Washington D.C.

Abstract

Abstract In the face of natural or manmade disasters, marginalized communities often bear disproportionate vulnerabilities, shaped by complex interplays of political, economic, demographic, and historical factors. This study employs the Pressure and Release (PAR) model to elucidate the roots of unequal resource distribution and varying vulnerability levels among communities. Focusing on Washington DC, the research delves into the social vulnerability of its Southeast communities through Pareto ranking and an additive model. Results reveal the advantages of Pareto ranking, emphasizing the intertwined nature of vulnerability factors. Concurrently, the study examines Green Stormwater Infrastructure (GSI) programs, revealing their exclusionary practices. Drawing on environmental justice literature, the research connects socio-economic indicators to infrastructure disparities. The study hypothesizes that comprehensive social vulnerability contributes to the unequal distribution of both grey and green stormwater infrastructure. The findings underscore the urgency of addressing maintenance neglect and community exclusion within GSI practices.
