Virtual Public Workshop

The County will present an overview of the project, describe our goals and objectives related to centering equity in the CAP Update, solicit feedback from attendees to aid in the identification of underserved/frontline communities within the unincorporated county, understand and define equity, develop an engagement approach that is inclusive and effective, and develop a greater understanding of the climate-related issues facing identified communities. Share our workshop flyer (English and Español) with your networks to help spread the word.

Public Participation

The County will be holding a series of public workshops throughout this year to present project updates and solicit feedback on the CAP Update project. In addition to these workshops, the County will be soliciting feedback in smaller group settings that provide an opportunity for focused discussion around topics that include transportation/built environment, agriculture, conservation, energy/water/waste, equity and environmental justice, and other important topics. All information convened from focused discussions will be integrated into future public workshops. If you are interested in being notified of our upcoming opportunities to participate, please sign up for our mailing list.

Project Public Scoping Meeting

Consistent with Section 21083.9 of the CEQA Statutes, a public scoping meeting was held virtually on January 28, 2021 to solicit comments regarding the scope and analysis of the Supplemental EIR.

Virtual Public Workshop

The County’s sustainability planning team advanced the CAP Update project at a virtual public workshop on April 21, 2021. The event drew more than 100 attendees and included a presentation on the project background, objectives, components, and timeline. Throughout the presentation, attendees participated in the discussion through interactive polling questions, and staff answered questions throughout the presentation and during an open discussion session at the end of the event

Project Background

On September 30, 2020, the County of San Diego (County) Board of Supervisors voted to set aside its approval of the County’s 2018 Climate Action Plan (2018 CAP) and related actions because the Final Supplemental Environmental Impact Report (2018 CAP SEIR) was found to be out of compliance with the California Environmental Quality Act (CEQA). In response to this Board action, staff are preparing a Climate Action Plan Update (CAP Update) to revise the 2018 CAP and correct the items identified by the Court within the Final 2018 CAP SEIR that were not compliant.

The overall objective of the CAP Update is to reduce greenhouse gas (GHG) emissions generated from activities within the unincorporated county (community) and GHG emissions generated by County facilities and operational activities throughout the county, including facilities and operations located within incorporated cities (County operations), to meet or exceed GHG reduction goals under State laws.

The CAP Update may consider strategies and reduction measures, and supporting efforts organized under the same five categories as the 2018 CAP:

Built Environment & Transportation


Solid Waste

Water & Waste Water

Agriculture & Conservation

Pending adoption of a new Climate Action Plan, the County will continue to implement the 26 GHG reduction measures and sustainability initiatives/programs identified in the 2018 CAP to reduce GHG emissions as part of its ongoing commitment to the environment and to meet the State’s 2030 reduction target.

Project Materials

A Supplemental Environmental Impact Report (SEIR) will be prepared for the CAP Update project. The project will include preparation of an updated GHG Emissions Inventory and Projections and preparation of updated GHG Emissions Targets to determine if additional or revised measures are needed.

The County seeks input from the public and agencies on potential environmental impacts of the CAP Update, ways to mitigate those impacts, and alternatives that may lessen those impacts. Additional Supplemental EIR information can be found here.

As part of the CAP Update project the County will also be preparing Smart Growth Alternatives for analysis in the CAP Update SEIR. If you would like to be involved and provide input on what goes into a Smart Growth Alternative, please e-mail us and we will reach out to you to schedule a discussion. All information shared and convened from focused discussions on Smart Growth Alternatives will be integrated into future public workshops.

County of San Diego

County of San Diego

The County has jurisdiction over the unincorporated areas within the county which are generally east and north of the City of San Diego, noted in dark grey on the map. The unincorporated area encompasses approximately 3,570 square miles with a population of 454,599 residents. The unincorporated area is home to 26 distinct communities that vary from suburban densities adjacent to incorporated cities (i.e., Lakeside, Spring Valley, and Sweetwater), to low density rural communities (i.e., Borrego Springs, Descano, and Pine Valley) surrounded by hillsides, deserts, and agricultural lands. The unincorporated county's most developed communities are located along the unincorporated county's westernmost boundaries where access to public facilities such as water, sewer, roads, and schools is readily available. 

Unincorporated lands are biologically rich and diverse, and are comprised of natural features that include lagoons, foothills, mountain ranges, and deserts. Large federal, state, and regional parklands cover much of the eastern portion of the county. Tribal lands comprise 5.7% of the land area and agricultural lands account for a large proportion of the privately-owned lands. 

Aligning with County Sustainability Efforts

The County's Climate Action Plan is aligned with and builds upon many other County efforts through complementary implementation-focused actions.
