7. Environmental Justice (EJ)
Communities
LEGEND
This is a draft version of the EJ Communities map that was released in
December 2020. The San Francisco Planning Department is still in the
process of gathering feedback from the general public and from other
agencies. Because of this, the EJ Communities map may be revised
during the fall or winter of 2021. CalEPA recently issued a draft of
CalEnviroScreen 4.0 (which is the most heavily weighted data source in
the EJ Communities Map), so it’s likely that the EJ Communities map will
be updated once CES 4.0 is finalized.

Area with high pollution burden (not included in OEHHA
CalEnviroScreen 3.0 due to missing data/low population)
