The County Auditor initiated the Audit Hotline to facilitate the reporting of information regarding observations of waste, fraud and misuse of resources related to County operations and programs. Oftentimes, information is also provided about non-County agencies. For those operations under the jurisdiction of the County Board or an Elected Official, audit procedures are performed relative to these allegations. For non-County agencies, an assessment is performed to determine the validity of the allegation and any possible impact upon a County operation. When appropriate, these latter inquiries are referred to the responsible agency or investigative authority.
The Auditor is responsible for auditing vouchers to be paid by the County Board and recommending their payment or rejection. The Auditor reports quarterly on the entire financial operations of the County, including revenues, expenditures, encumbrances, and changes in fund balance for the County's operating funds. The
Quarterly Financial Reports are available here.
