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.
