At the time the commission makes each allocation under this chapter, it shall so certify to the State Controller. The commission shall present claims for reimbursement of the state’s share of the cost of construction of projects under any allocations to the State Controller for payment. The State Controller shall make such audit as he deems necessary, before or after disbursement, for the purpose of determining that the money allocated has been expended for the purposes and under the conditions authorized under this chapter; except that prior or subsequent review and approval by the city, county, or city and county in which the grade-crossing protection is maintained of such allocations shall not be required as a condition of disbursement.
