Initiated by the County’s Board of Supervisors, the Green Zones Program aims to address the environmental justice issues within the unincorporated communities in the County. Environmental Justice (EJ) means fair treatment and meaningful involvement of all people, specifically in the frame of environmental policies. In concerns pollution impact and its risks that disproportionately burden disadvantaged communities and sensitive receptors, such as residents, schools, daycare, etc. The Green Zones Program aims to develop a set of land use tools and implementation plans to address EJ issues with various stakeholders, grassroots organizations, agencies, and communities.


Environmental Justice is a broad issue that touches upon various aspects of land use planning. A key concept in EJ is transparency and community engagement in the process. In order to create implementable and effective planning tools, the Green Zones Program employs data-driven approach and robust stakeholder outreach strategy. It consists of the following components:

Land Use Policy

EJ issues are inherently related to land use incompatibility and regulations. Pollution emissions sources located nearby neighborhoods or schools pose serious threats on residents’ health as well as environment. The Green Zones Program will highlight land use policies to address the impact of pollution at the sources.

Prevention and Mitigation

It is critical to consider the impact of environmental pollution on health risk during land use review process. The Green Zones Program aims to develop land use tools that can be implemented through zoning code and coordination among agencies to help mitigate, reduce and prevent health risks from toxic pollutants.

Community Engagement

The core value of EJ is information transparency and collaboration with various stakeholders, experts, and community members. The Green Zones Program will be developed through rigorous community engagement process to identify community needs, shape the goals and policies in addressing EJ, and raise awareness in neighborhoods.

Toxic Hotspots Map

One of the program objectives is to develop a map tool that identifies the stationary sources of pollution and analyzes cumulative impact. Input from experts and community members will be incorporated. This tool will be used as a foundation for land use policies and zoning requirements that concern EJ, as well as a public resource for inter-departmental coordination and EJ communities.
