Climate Action Plan Update Supplemental EIR

PDS2020-POD-20-016; PDS2020-GPA-20-004; PDS2020-ER-20-00-002

Project Description

A Draft Supplemental Environmental Impact Report (Draft SEIR) has been prepared for the Climate Action Plan (CAP) Update project. The project entails the County’s CAP that includes measures and actions to reduce GHG emissions from the unincorporated county and County operations. The CAP necessitates changes to Goal COS-20 and Policy COS-20.1 of the 2011 County of San Diego General Plan Update (GPU) and mitigation adopted in the certified Final Program Environmental Impact Report (PEIR) for the 2011 GPU (Mitigation Measures CC-1.2, CC-1.7, and CC-1.8). As a result, an associated action of the project is a General Plan Amendment to the 2011 GPU, which includes revised mitigation measures and a revised Mitigation, Monitoring, and Reporting Program for the 2011 GPU PEIR. The project also includes a threshold of significance for GHG emissions and revised Guidelines for Determining Significance for Climate Change, as well as a CAP Consistency Review Checklist. All of these actions constitute the project analyzed in the Draft SEIR.

Electronic copies of these documents are available for review below.

Comments on the Draft SEIR must be received in writing no later than January 05, 2024, at 4:00 PM.

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.
