The board meets in the Eau Claire County Courthouse in downtown Eau Claire, with its weekly meetings televised on local public television and transcripts published online. Most items are approved on a "consent calendar" without discussion. Public comment is limited to three minutes per individual per item.
Eau Claire County is in Wisconsin State Senate district 31, represented by Jeff Smith (D). The county is divided into two Wisconsin assembly districts: Assembly district 93 which is represented by Christian Phelps (D), as well as district 91 which is represented by Jodi Emerson (D).
