Roadside herbicide application in Placerville, CA

VDOT has sprayed 163 miles of Albemarle County roadsides with the herbicide Krenite S this year, a brush control agent.  This month, the Albemarle Board of Supervisors passed a resolution requesting advance notice of these operations to allow citizens to be notified. 

To what lengths would you want local government to inform property owners of spraying along rural roads?
