Ala. Code § 45-59-130.10: Requisition for Expenditure of Funds; Appropriation by Commission.

The authority of the county engineer shall be limited to the expenditure of funds for the purpose of construction, maintenance, or repairs of public roads, bridges, and highways of St. Clair County as may be set aside and appropriated by the county commission, as hereinafter provided. It shall be the duty of the county commission at some meeting in September of each calendar year, or not later than the first meeting in October following, by order or resolution spread upon the minutes, to fix and determine the amount of funds which will be available for the purpose of building, maintaining, and constructing public roads, bridges, and highways of St. Clair County for the current fiscal year, beginning on October 1st, which the county engineer and his or her necessary expenses, shall not be exceeded by him or her in building, maintaining, and constructing public roads, bridges, and highways in St. Clair County during the period. The county commission is authorized, from time to time within any period, to increase the amount so allowed to be expended by the county engineer during the period, when such authorization will not conflict with the general law under the Budget Act and the Budget Management Act, and if such funds are presently available, and have not heretofore been set aside by the present County Commission of St. Clair County. Immediately upon September 20, 1971, it shall be the duty of the county commission to set aside a sufficient portion of the funds for the maintenance of roads, bridges, and highways until the meeting in September or October, 1971, as hereinabove provided for.
