Petition for writ of mandate filed.
Sierra Club challenged the County of San Diego’s mitigated negative declaration (MND) under the California Environmental Quality Act for the Greenhills Ranch Phase 2 Project, a 63-home subdivision on 19 acres. The petition alleged that the MND lacked substantial evidence to support its conclusion that environmental impacts would not be significant, including impacts on wildfire safety, greenhouse gas emissions, and biological resources. Sierra Club alleged that greenhouse gas emissions that would result from the project would contravene the County’s climate goals, State greenhouse gas reduction targets, and State laws to reduce vehicle miles traveled.
