Board directs Public Works to develop public notice rules for herbicide use after residents press for transparency

After public speakers described seeing herbicide applications near public trails, the Orange County Board of Supervisors on June 23 directed Public Works to develop a responsible public‑notice policy for proposed herbicide or pesticide use in county public spaces.

Vice Chair Katrina Foley said residents deserve to know what product will be used, the general area and the dates during which work will occur so they can avoid treated areas. Creek advocacy groups documented instances where contractors sprayed vegetation close to trails on windy days and urged prominent signage and online disclosure.

Public Works staff told the board the county already complies with Department of Pesticide Regulation annual notification requirements for agency partners and that vector‑control partners receive advance notice; the directive asks staff to develop public‑facing notices that include product names, purpose, general area and contact information. Staff and the sheriff’s department will also evaluate whether additional site security or staff‑safety measures are needed where public notice could attract demonstrations.

Supervisor concerns centered on balancing transparency with employee safety. The board unanimously approved the direction and asked Public Works to return with a proposed noticing policy that preserves operational safety while increasing public information.

The action does not immediately change spraying practices but requires staff to propose a formal public‑notice regimen for board review.
