Mitchoff’s retirement creates an opportunity for 5 CoCo Board of Supervisors candidates

Contra Costa County District 4 Supervisor Karen Mitchoff — also the chairperson of the board this year — is retiring at the end of the year, leaving some big shoes to fill.

Her seat, which includes parts of Walnut Creek, Pleasant Hill, Concord and Clayton, seems to be very popular. Five local officials want the job, all of them well-credentialed and known in county circles.
