This tool, the first of its kind in Maryland (MD), represents an important advancement in environmental justice (EJ) decision making. In 2018, MDNR partnered with the authors to update the tool's rudimentary model for identifying communities with low park equity and to improve the tool's overall function and design. The updated tool scores census block groups (CBGs) in MD based on the following nine factors: population density, concentration of households <185% of the federal poverty line, concentration of children under the age of 18 years, concentration of adults 65+, concentration of non-White households, distance to public park space, distance to public transportation, and walkability, and linguistic isolation. This article provides details and rationale regarding the indicators and formula used to assign park equity scores to each CBG. The details of added user-driven functions are also described. Finally, we demonstrate the tool's utility for regional planning and decision support with a case study in a suburban EJ community.
