Background The State apportions funds monthly from the Highway Users Tax Account (HUTA) in the Transportation Tax Fund to cities and counties for the construction, maintenance, and operation of local streets and roads. The highway users taxes derive from state taxes on the sale of motor vehicle fuels. In accordance with Streets and Highways Code, cities must establish individual Special Gas Tax Street Improvement Funds for the deposit of their HUTA fund apportionments. Additionally, cities must expend its HUTA fund apportionments only for street-related purposes in accordance with Article XIX of the California Constitution and Streets and Highways Code. We conducted our audit of the city’s Special Gas Tax Street Improvement Fund under the authority of Government Code section 12410. Objective, Scope, Our audit objective was to determine whether the city accounted for and and Methodology expended its Special Gas Tax Street Improvement Fund in compliance with Article XIX of the California Constitution and Streets and Highways Code. We audited the city’s Special Gas Tax Street Improvement Fund for the period of July 1, 2015, through June 30, 2016. To achieve our objective, we:  Gained a limited understanding of internal controls that would have an effect on the reliability of the accounting records of the Special Gas Tax Street Improvement Fund by interviewing key personnel, completing the internal control questionnaire, and reviewing the city’s organization chart;  Conducted a risk assessment to determine the nature, timing, and extent of substantive testing;  Performed analytical procedures to determine and explain the existence of unusual or unexpected account balances;  Verified the accuracy of fund balances by performing a fund balance reconciliation for the period of July 1, 2006, through June 30, 2015, and by recalculating the trial balance for the period of July 1, 2015, through June 30, 2016; -1- City of Petaluma Special Gas Tax Street Improvement Fund  Verified whether the components of and changes to fund balances were properly computed, described, classified, and disclosed by scheduling and analyzing the Special Gas Tax Street Improvement Fund account balances;  Reconciled the fund revenue recorded in the city ledger to the balance reported in the SCO’s apportionment schedule for fiscal year 2015-16 to determine whether HUTA apportionments received by the city were completely accounted for;  Analyzed the system used to allocate interest and determined whether the interest revenue allocated to the Special Gas Tax Street Improvement Fund was fair and equitable, by interviewing key personnel and recalculating all interest allocations for the audit period;  Reviewed the fund cash and liabilities accounts for unauthorized borrowing to determine whether unexpended HUTA funds were available for future street-related expenditures and protected from impairment; and  Verified whether the expenditures incurred during the audit period were supported by proper documentation and eligible in accordance with the applicable criteria by testing all of the expenditure transactions that were equal to or greater than the significant item amount (calculated based on materiality threshold), and judgmentally (non-statistically) selecting samples of other transactions for the following categories: o Services and Supplies – We tested $33,775 of $36,275. o Transfers – We tested $187,248 of $1,851,262 in total transfers. For the selected sample, errors found, if any, were not projected to the intended population. We did not audit the city’s financial statements. We limited our audit scope to planning and performing audit procedures necessary to obtain reasonable assurance that the city accounted for and expended its Special Gas Tax Street Improvement Fund in accordance with the criteria. We considered the city’s internal controls only to the extent necessary to plan the audit. We conducted this performance audit in accordance with generally accepted government auditing standards.
