When a CA local jurisdiction (county or city) is adopting or revising two or more general plan elements concurrently, SB 1000 calls for the jurisdiction to consider if it's required to pursue an EJ element by going through a screening process for identifying disadvantaged communities:

1. Use CalEnviroScreen to examine whether the planning area for the general plan contains Disadvantaged Community (DAC) census tracts that have a combined score of 75% or higher.
2. Map the household median incomes by census tract in the planning area at or below statewide median income and examine for disproportionate pollution burden.
3. Map the household median incomes by census tract in the planning area at or below the Department of Housing and Community Development's state income limits and examine for disproportionate pollution burden.
4. Incorporate and analyze community-specific data and examine for additional pollution burden and health risk factors.

Using this screening method, the County has identified the unincorporated communities Ashland, Cherryland, Hayward Acres, and parts of Castro Valley and San Lorenzo as the Priority Communities for the County's EJ Element. For the purposes of EJ Element Implementation, the Board of Supervisors has designated all of the unincorporated Eden Area - which includes Ashland, Cherryland, Hayward Acres, and San Lorenzo -- as Priority Communities alongside the applicable census tracts in Castro Valley.
