Audit Plan

The County Auditor prepares an annual audit plan for review by the Board-Appointed Audit Committee and approval by the Board of Supervisors. The selected audit areas are the result of a formal risk-assessment process.  This process can be found in our Risk Assessment Reports.  The Board of Supervisors must approve any additions, deletions, or deferrals to the approved audit plan.
