City of

, California (the City) including the Air Quality Improvement Special Revenue Fund (the Fund) of the City, as of and

Internal Control over Financial Reporting
In planning and performing our audit of the Fund’
s financial statements, we considered the City’s
internal control over 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 st
atements, but not for the purpose of expressing an opinion on the effectiveness of the City’s internal control. Accordingly, we do not express an opinion on the effectiveness of the 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 th e 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 interna
l control that we consider to be material weaknesses. However, material weaknesses may exist that have not been identified.
Compliance and Other Matters
As part of obtaining reasonable assurance about whether the City’s Fund financial statements are free from material misstatement, we performed tests of its compliance with certain provisions of laws, regulations, contracts and grant agreements, noncompliance with which could have a direct and material effect on the financial statement
s
. Such provision
s include those provisions of laws
and regulations identified in Assembly Bill 2766 Chapter 1705 [Health and Safety Code Sections 44220 through 44247] (the Guide).
However, providing an opinion on compliance with those provisions was not an objective of o ur
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 and the results of that testing, and not to provide an opinion on the effectiveness of the City’s internal control or on compliance. This report is
an integral part of an audit performed in
accordance with
Government Auditing Standards
and the Guide in considering the City’s internal
control and compliance. Accordingly, this communication is not suitable for any other purpose.
