INDEPENDENT AUDITORS' REPORT ON INTERNAL CONTROL OVER
FINANCIAL REPORTING AND ON COMPLIANCE AND OTHER MATTERS
BASED ON AN AUDIT OF FINANCIAL STATEMENTS PERFORMED
IN ACCORDANCE WITH GOVERNMENT AUDITING STANDARDS
Honorable Mayor and Members of the City Council
City of Riverside
Riverside, California
We have audited, in accordance with the auditing standards generally accepted in the United States of America and the standards applicable to financial audits contained in Government Auditing Standards issued by the Comptroller General of the United States, the financial statements of the City of Riverside (the City), including the Air Quality Improvement Special Revenue Fund (the Fund) which is included in the aggregate remaining fund information of the City, as of and for the year ended June 30, 2025, and the related notes to the financial statements, which collectively comprise the City's basic financial statements, and have issued our report thereon dated December 23, 2025.
Report on Internal Control Over Financial Reporting
In planning and performing our audit of the financial statements, we considered City's internal control over the Fund's financial reporting (internal control) as a basis for designing audit procedures that are appropriate in the circumstances for the purpose of expressing our opinions on the financial statements, but not for the purpose of expressing an opinion on the effectiveness of City's internal control. Accordingly, we do not express an opinion on the effectiveness of City's internal control.
A deficiency in internal control exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent, or detect and correct, misstatements on a timely basis. A material weakness is a deficiency, or a combination of deficiencies, in internal control, such that there is a reasonable possibility that a material misstatement of the entity's financial statements will not be prevented, or detected and corrected, on a timely basis. A significant deficiency is a deficiency, or a combination of deficiencies, in internal control that is less severe than a material weakness, yet important enough to merit attention by those charged with governance.
Our consideration of internal control was for the limited purpose described in the first paragraph of this section and was not designed to identify all deficiencies in internal control that might be material weaknesses or significant deficiencies. Given these limitations, during our audit we did not identify any deficiencies in internal control that we consider to be material weaknesses. However, material weaknesses or significant deficiencies may exist that were not identified.

Report on Compliance and Other Matters
As part of obtaining reasonable assurance about whether Fund's financial statements are free from material misstatement, we performed tests of its compliance with certain provisions of laws, regulations, contracts, and grant agreements, including the requirements of California Assembly Bill 2766, Chapter 1705 (44220 through 44247), noncompliance with which could have a direct and material effect on the financial statements. However, providing an opinion on compliance with those provisions was not an objective of our audit, and accordingly, we do not express such an opinion. The results of our tests disclosed no instances of noncompliance or other matters that are required to be reported under Government Auditing Standards.
Purpose of This Report
The purpose of this report is solely to describe the scope of our testing of internal control and compliance. Accordingly, this communication is not suitable for any other purpose.
