Internal Audit Reporting

Annual Internal Audit Plan

To establish the Internal Audit Department's workload, the City Auditor presents an Annual Internal Audit Plan to the City Council for approval each year.  To see what the Department will be working on this year, access the current Annual Internal Audit Plan (PDF).

Quarterly Reports

Using this Plan, the Internal Audit Department evaluates City programs and services and periodically releases audit reports. The Department releases Quarterly Reports to summarize its progress on completing the Annual Internal Audit Plan and provide updates on the Department's condition. 

Department Standards & Peer Review

To comply with Generally Accepted Government Auditing Standards, audit offices are periodically peer reviewed. In 2022, the Internal Audit Department received the highest peer review opinion possible. Read the full peer review opinion letter (PDF).
