(1) No payment shall be made or obligation incurred against any allotment or appropriation except in accordance with appropriations duly made unless the City Manager or his designee first certifies that there is a sufficient unencumbered balance in such allotment or appropriation and that sufficient funds therefrom are or will be available to cover the claim or meet the obligation when it becomes due and payable.
(2) Any authorization of payment or incurring of obligation in violation of the provisions of this Charter shall be void and any payment so made illegal. Such action shall be cause for removal of any officer who knowingly authorized or made such payment or incurred such debt or obligation, and he shall also be liable to the City for any amount so paid.
(3) This prohibition shall not be construed to prevent the making or authorizing of payments, or making contracts for capital improvements to be financed wholly or partly by the issuance of bonds, time warrants, certificates of indebtedness, or certificates of obligation, or to prevent the making of any contract or lease providing for payments beyond the end of the fiscal year, providing that such action is made or approved by ordinance.
(4) The City Manager shall submit to the City Council each month a report covering revenues and expenditures of the City in such form as requested by the City Council.
