Traffic Advisory Committee

The Traffic Advisory Committee was formed in 1965 by the El Dorado County Board of Supervisors to provide a more efficient and systematic method of determining the necessity of requested traffic control device installations and to investigate and report to the Board on these requests.  The El Dorado County Traffic Advisory Committee is comprised of five voting members and various advisory staff members who meet twice a year (Spring & Fall) in a meeting open to the public, to discuss and review speed surveys and requests for regulatory traffic controls on county-maintained roads. These controls include speed limits, stop signs, traffic signals, and parking regulations.
Current Members: 
Rafael Martinez, Department of Transportation Director
Nathan Haynes, Department of Transportation Deputy Director 
Commander Rick Hatfield, California Highway Patrol
Lieutenant Troy Morton, El Dorado County Sheriff Department
Karen Bianchini, El Dorado County Risk Manager
 
Advisory Staff:
