Weights & Measures

The Department of Agriculture/Weights and Measures enforces the laws and regulations of the California Food and Agriculture Code, the California Business & Professions Code and the California Code of Regulations while serving at the discretion of the County Board of Supervisors and CDFA's  Secretary of Food & Agriculture. Sonoma County's Department of Agriculture/Weights & Measures employs a staff of thirty-three people and has its main office in Santa Rosa.  To serve the public's needs, two small satellite offices with limited public hours are operated in the cities of Sonoma and Petaluma.

Fee Increases effective July 1, 2019

On May 14, 2019, the Sonoma County Board of Supervisors adopted changes to the fee schedule to help recover reasonable costs of providing an array of services pertaining to local, state, and federal regulation of agriculture and cannabis in Sonoma County.  These changes are effective July 1, 2019.  The changes include fees for the hazardous materials program (Certified Unified Program Agency [CUPA]), Vineyard and Orchard Site Development (VESCO) program, Agricultural Grading and Drainage program, and the Cannabis Cultivation program.  The approved increase for these programs is 3%, which covers the increases in costs to provide those services. 

As part of the fee review process, the Department always seeks to increase efficiencies where possible.  For VESCO, staff examined the process of including the Permit Sonoma's parcel Zoning and Well and Septic permit review costs with the VESCO project applications.  Through consultation with Permit Sonoma, it was decided that those project reviews would be handled in-house, as part of the normal VESCO review process.  Doing this saves the project applicants time and costs.  So, if your project had a grading and drainage aspect to it, you can expect to save $257 on the project permit fee.  

Our fees web page will update on July 1, 2019 to reflect these changes.

The Land Stewards Guide to Vineyard and Orchard Erosion Control

Through a Specialty Crop Block Grant from the California Department of Food and Agriculture, the Land Stewardship Division of the Sonoma County Department of Agriculture/Weights & Measures was able to create The Land Steward’s Guide to Vineyard and Orchard Erosion Control.  The Guide focuses on assessing and maintaining croplands beyond their initial development.  Our goal was to provide a tool that Sonoma County growers could utilize throughout the life of their vineyard or orchard to aid them in erosion control, nutrient management, and pesticide use planning.
