Green stormwater infrastructure in New Haven, Connecticut and socioeconomic variables within neighborhoods and census block groups

Green infrastructure increasingly is used to ameliorate water quality and quantity problems caused by runoff in cities. Studies show how the spatial distribution of these Green Stormwater Infrastructure (GSI) sites are unevenly distributed relative to socioeconomic and demographic groups. Often this is described as an indicator of perpetuated environment injustice, given the purported social and environmental benefits of GSI. To assess equity, researchers often examine either who gets what with respect to environmental ‘goods’ such as tree canopy and other green infrastructures, or investigate the procedures, decision making processes, and power structures pertaining to planning processes. The data publication contains GSI location data collected from 2013-2021. It also contains information regarding who lives in nearby New Haven, Connecticut. Specifically, these data include four (4) vector polygon shapefiles representing census block groups, neighborhoods, sewer, and watershed outlines and two (2) point shapefiles representing green infrastructure and combined sewer overflow locations. An R Markdown (.rmd) file is also included containing analysis steps.The intention of providing these data is to accelerate and enable other future researchers interested in GSI and Environmental Justice, and to allow students to access data for use in classes in geographic information systems, urban studies, statistics, environmental justice, and related.For more information about this study and these data see Locke et al. (2021).
