Purpose Statement

Internal Audit serves the community by ensuring transparency and accountability over the use of public funds.

We assist the City and its departments in achieving superior service and establishing sustainable practices by objectively analyzing and evaluating operations and recommending improvements to promote efficiency and effectiveness.

Role of the Internal Audit Office

The Internal Audit Office is responsible for providing management with independent, timely, and relevant information concerning the City's programs, activities, and functions. Internal Audit recommends improvements to policies and procedures that will enhance the internal control structure of the City. Internal Audit's work is vital in maintaining the general public's trust and confidence that City resources are being used effectively and efficiently.

We employ the following auditing, educational and consultative services:

  • appraising and articulating the adequacy of internal controls,
  • educating city personnel on standards of internal control,
  • reporting on the integrity of information,
  • determining compliance with laws, regulations and contracts,
  • assessing whether assets are adequately safeguarded,
  • assessing the efficiency and effectiveness of operations,
  • appraising the extent to which objectives are accomplished,
  • offering investigative services, as needed,
  • providing analyses to facilitate decision making,
  • testing transactions for compliance with accepted business practice,
  • auditing for proper management and accounting of financial resources.
