In Sierra Club v. County of San Diego, (2014) WL 6657169, the court held that the County violated CEQA by failing to implement measures to mitigate greenhouse gas (“GHG”) emissions that would occur as a result of the County’s 2011 General Plan Update.

The County adopted its General Plan Update based on a Program Environmental Impact Report (“PEIR”). The PEIR included Mitigation Measure CC-1.2, under which the County committed to preparing a climate action plan (“CAP”) with “more detailed greenhouse gas emissions reductions targets and deadlines” and “comprehensive and enforceable GHG emissions reduction measures that will achieve” specified quantities of GHG reductions by the year 2020.  However, the court held that the CAP that the County later adopted did not meet the requirements of Mitigation Measure CC-1.2.  It found that the County admitted that the CAP would not ensure the required reductions, that many of the emissions reduction measures were unfunded, that the County was not making meaningful efforts to implement or fund transit-related measures, and that the CAP had no deadlines. 

In Save Our Uniquely Rural Community Environment v. County San Bernardino, (2015) 235 Cal.App.4^th 1179, the trial court granted an environmental group’s petition for a writ of mandate concerning  a proposed community center and mosque, for which the county planning board had adopted a mitigated negative declaration (MND) and issued a conditional use permit (CUP), and the court ordered the MND and CUP be set aside solely for purposes of obtaining further CEQA review on the single issue of waste water treatment.
