The board shall establish the beginning and ending of its fiscal year, which period shall constitute its budget year, and at least thirty days prior to the beginning of the first full fiscal year after the creation of the authority and annually thereafter the treasurer shall prepare and submit to the board a tentative budget. Such tentative budget shall be considered by the board, and, subject to any revisions or amendments that may be determined by said board, shall be adopted as the budget for the ensuing fiscal year. No expenditures in excess of the budget shall be made during such fiscal year unless expressly authorized and directed by the board. It shall not be necessary to include in such budget any statement of necessary expenditures for annual interest or principal payments on bonds or for capital outlays, but it shall be the duty of the board to make provisions for their payment as they become due.
