Census Tracts Identified as BAAQMD Overburdened Communities for the Bay Area Regional Climate Action Planning Initiative Frontline Communities Map

Shapefile contains census tracts identified as overburdened by the Air District for the five counties that are included in the Bay Area Regional Climate Action Planning Initiative Frontline Communities Map. The original shapefile was obtained from the Bay Area Air Quality Management District staff. The “Clip” tool in ArcMap was used to select only those features which are located within the boundaries of the five Bay Area counties included in the Frontline Communities Map. No display filters were used to visualize the features in the final map. The Frontline Communities Map is meant to help identify communities that are considered frontline communities for the purpose of the USEPA’s Climate Pollution Reduction Grant (CPRG) program’s planning effort, which is a five-county climate action planning process led by the Air District. USEPA refers to these communities as low-income and disadvantaged communities (LIDACs). Effective July 1, 2022, Air District permit regulations set more stringent health risk limits and public noticing requirements for projects located in overburdened communities, as defined in Regulation 2-1-243 which was adopted on December 15, 2021. An Overburdened Community is defined as an area located within: • A census tract identified by CalEnviroScreen (CES) 4.0 as having an overall CES score at or above the 70th percentile, or • Within 1,000 feet of any such census tract.
