Criteria: The Uniform Guidance requires the City to establish and maintain effective internal control over compliance for federal awards, including controls to reasonably ensure that costs charged to federal programs are allowable, properly supported, and comply with applicable federal requirements and the terms and conditions of the award. Under 2 CFR 200.403, costs charged to a federal award must be allowable, including that they be adequately documented and not be included as a cost or used to meet cost-sharing requirements of any other federally financed program in the current or a prior period. Condition: The City did not have adequately designed and implemented review controls over certain material project costs included in reimbursement requests submitted to the pass through agency. Our testing identified that the city submitted the same eligible project cost for reimbursement under two different federal grant awards, of which one was denied for reimbursement Cause: The City lacked sufficiently designed or effectively operating controls over the preparation, review, and approval of reimbursement requests for federal awards. In particular, the City's controls did not include an effective reconciliation of expenditure detail by invoice, pay application, or other unique transaction identifier across open grant awards before submission of reimbursement requests. Effect: The absence of effective review controls over material project costs increases the risk that ineligible, unsupported, or incorrectly costs could be included in reimbursement requests without timely detection and correction. The duplicate submission was not reimbursed from both federal awards and therefore does not require repayment or adjustment of reimbursement requests. This deficiency is considered a material weakness in internal control over compliance for the Department of Transportation program. Recommendation: We recommend that the City design and implement formal, documented review procedures over material project costs included in reimbursement requests. These procedures should include defined review responsibilities, documentation of the review performed, review of other federal funding reimbursement request, and supervisory oversight to ensure that all high-dollar or complex transactions are reviewed for eligibility, accuracy, and adequate supporting documentation before submission.Management Response: Management acknowledges the finding and will continue to review and controls to ensure all costs included in reimbursement requests are allowable.
