Planning Division Sections

Comprehensive Planning

The Comprehensive Planning team leads the County of Sonoma’s long-range land use planning and policy efforts. Also known as advance planning, the work is primarily focused on creating a long term vision for the people of Sonoma County, which is directed by the county’s General Plan.

All land in unincorporated Sonoma County is guided by its General Plan, which was last comprehensively updated in 2008. Under the leadership of the Sonoma County Board of Supervisors, the team delivers a work plan that includes working directly with Permit Sonoma customers and leading a number of County initiatives through an inclusive community engagement strategy.

Natural Resources

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

Project Review

The Project Review section reviews new development proposals for conformance with the County's General Plan and Zoning Code Regulations. They also evaluate environmental impacts of private development proposals and coordinate with other Permit Sonoma divisions, such as building and engineering, to ensure that standards for building safety and water resources are incorporated into new development.
