Natural Resources

The Natural Resources section (formerly Environmental Review) of the Planning Division evaluates the environmental impact of public projects, such as bridges, roads, and airport projects, to comply with the California Environmental Quality Act (CEQA) and other laws and regulations that protect water quality, biotic and cultural resources. Natural Resources staff also prepares Environmental Impact Reports (EIRs) for private projects.

Natural Resources staff also work with resource agencies during the planning and design of public projects and obtain all applicable permits. They develop and implement mitigation and monitoring programs to ensure that biotic and cultural resources are protected during project construction and operation.

Environmental Review Guidelines

California Environmental Quality Act (CEQA)

The California Environmental Quality Act (CEQA) generally requires state and local government agencies to inform decision makers and the public about the potential environmental impacts of proposed projects, and to reduce those environmental impacts to the extent feasible. If a project subject to CEQA will not cause any adverse environmental impacts, a public agency may adopt a brief document known as a Negative Declaration. If the project may cause adverse environmental impacts, the public agency must prepare a more detailed study called an Environmental Impact Report (EIR). An EIR contains in-depth studies of potential impacts, measures to reduce or avoid those impacts, and an analysis of alternatives to the project. A key feature of the CEQA process is the opportunity for the public to review and provide input on both Negative Declarations and EIRs.
