The treasurer of the county in which a public transportation benefit area authority is located shall be ex officio treasurer of the authority. In the case of a multicounty public transportation benefit area the county treasurer of the largest component county, by population, shall be the treasurer of the authority. However, the authority, by resolution, and upon the approval of the county treasurer, may designate some other person having experience in financial or fiscal matters as treasurer of the authority. Such a treasurer shall possess all of the powers, responsibilities, and duties the county treasurer possesses for a public transportation benefit area authority related to investing surplus authority funds. The authority may (and if the treasurer is not a county treasurer, it shall) require a bond with a surety company authorized to do business in the state of Washington in an amount and under the terms and conditions the authority, by resolution, from time to time finds will protect the authority against loss. The premium on any such bond shall be paid by the authority.
All authority funds shall be paid to the treasurer and shall be disbursed by the treasurer only on warrants issued by the county auditor, upon orders or vouchers approved by the authority. However, the authority may, by resolution, designate some person having experience in financial or fiscal matters, other than the county auditor, as the auditor of the authority. Such an auditor shall possess all of the powers, responsibilities, and duties that the county auditor possesses for a public transportation benefit area authority related to creating and maintaining funds, issuing warrants, and maintaining a record of receipts and disbursements.
The treasurer shall establish a "transportation fund," into which shall be paid all authority funds, and the treasurer shall maintain such special accounts as may be created by the authority into which shall be placed all money as the authority may, by resolution, direct.
If the treasurer of the authority is a treasurer of the county, all authority funds shall be deposited with the county depositary under the same restrictions, contracts, and security as provided for county depositaries. If the treasurer of the authority is some other person, all funds shall be deposited in such bank or banks authorized to do business in this state that have qualified for insured deposits under any federal deposit insurance act as the authority, by resolution, shall designate.
An authority may provide and require a reasonable bond of any other person handling moneys or securities of the authority, but the authority shall pay the premium on the bond.
The county or counties and each city or town which is included in the authority shall contribute such sums towards the expense for maintaining and operating the public transportation system as shall be agreed upon between them.
