*Notice of Preparation Public Review Extended*

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:

  1. Built Environment and Transportation;
  2. Energy;
  3. Solid Waste;
  4. Water and Wastewater; and
  5. Agriculture and 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 NUMBER(S):          PDS2020-POD-20-016 and PDS2020-GPA-20-004

ENV. REVIEW NUMBER:        PDS2020-ER-20-00-002

Project Description

A Supplemental Environmental Impact Report (Supplemental EIR) 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.

To incorporate GHG reduction goals under new State laws adopted since 2011, the project will include amendments to Goal COS-20 and Policy COS-20.1 of the General Plan and 2011 GPU PEIR Mitigation Measures CC-1.2, CC-1.7, and CC-1.8, similar to the 2018 CAP. Policy COS-20.1 was also amended in 2018 so that the CAP could be used in the analysis of cumulative GHG impacts of projects covered by the CAP (e.g., projects consistent with density allowed in the General Plan), pursuant to CEQA Guidelines section 15183.5. The amendments to Goal COS-20 and Policy COS-20.1, a threshold of significance for GHGs, and a revised Guidelines will be required. These actions, analysis of GHG reduction measures, and any other action necessary to comply with CEQA will be analyzed in the Supplemental EIR for the project.

Notice of Preparation

On December 10, 2020, the County sent public notice that a Supplemental Environmental Impact Report (Supplemental EIR) will be prepared for the CAP Update. 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. The County also seeks input on potential GHG reduction strategies and measures to be included in the CAP Update.

Comments on this Notice of Preparation document were accepted for 57 days following the issuance of the first notice on December 10, 2020, and must be received no later than February 4, 2021. The County provided 27 extra days.

Comment letters may be submitted electronically via e-mail at:

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. 


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