On March 16, 2018, the Sierra Club and several other environmental and climate oriented organizations (Petitioners) filed a Writ of Mandate in San Diego Superior Court against the County of San Diego. The Writ challenges the County of San Diego’s February 14, 2018 adoption of its:
- Revised Climate Action Plan (CAP);
- Final Supplemental Environmental Impact Report (EIR);
- Guidelines and new Thresholds that determine whether a project’s Greenhouse Gases (GHGs) emission are significant or insignificant under California Environmental Quality Act (CEQA); and
- Under the Guidelines, an allowance for a project that requests a General Plan amendment (GPA project) to be found consistent with the Revised CAP if the project incorporates design features from the Guideline Checklist and uses post project approval GHG offsets from a geographic priority list—approved at the discretion of the Director of Planning and Development Services—for GHG emissions not prevented by the incorporated Checklist design features.
