Ala. Code § 11-43C-73

In any budget year, in anticipation of the collection of revenues, the council may by resolution authorize the borrowing of money by the issuance of negotiable notes of the city, each of which shall be designated “revenue note for the year _____ (stating the budget year).” Such notes may be renewed from time to time, but all such notes, together with the renewals, shall mature and be paid not later than the end of the fiscal year after the budget year in which the original notes have been issued. Such borrowing shall be subject to any limitation provided by law.
