a. Subject to the quarterly spending allotments and aggregate position and salary limits established pursuant to section one hundred six, and to other applicable provisions of this charter, of the civil service law and of other law, changes in schedules, within units of appropriation, may be made by the head of each agency. Any such changes shall be reported to the mayor and the comptroller before the effective date thereof, and shall be made available for public inspection under reasonable terms and conditions.
b. The mayor during any fiscal year may transfer part or all of any unit of appropriation to another unit of appropriation, except that when any such transfer (1) shall be from one agency to another or (2) shall result in any unit of appropriation having been increased or decreased by more than five percent or fifty thousand dollars, whichever is greater, from the budget as adopted for such unit of appropriation, the mayor shall notify the council of the proposed action. Within thirty days after the first stated meeting of the council following the receipt of such notice, the council may disapprove the proposed action; provided, however, that the mayor may recommend such a transfer if it is related to an appropriation included in the budget pursuant to section one hundred two only with the concurrence of the relevant borough president; and a borough president may make such a recommendation with regard to such an appropriation if it is concurred in by the mayor and does not include a reduction in an appropriation other than one included in the budget pursuant to section one hundred two on the recommendation of such borough president. Written notice of any transfer pursuant to this subdivision shall be given to the comptroller and shall be published in the City Record as soon as possible after such transfer.
c. The provisions of this section shall not be deemed to authorize any transfer from appropriations required by law.
d. The council may during any fiscal year transfer part or all of any unit of appropriation within the council appropriation to any other council unit of appropriation for any of its programs or projects or for any other purpose, solely by adoption of a council resolution. Each such transfer shall be published in the City Record and written notice thereof shall be given to the mayor and to the comptroller not less than ten days before the effective date thereof.
e. The procedures and required approvals pursuant to sections two hundred fifty-four, two hundred fifty-five, and two hundred fifty-six, without regard to the dates specified therein, shall be followed in the case of: (1) any proposed amendment to the budget respecting the creation of new units of appropriation, or (2) the appropriation of new revenues from any source except for revenues from federal, state or private sources in regard to the use of which the city has no discretion; provided, however, that the mayor shall give notice to the council of the receipt and proposed utilization of any such revenues, or (3) the proposed use by the city of previously unappropriated funds received from any source. Any request by the mayor respecting an amendment to the budget that involves an increase in the budget shall be accompanied by a statement of the source of current revenues or other identifiable and currently available funds required for the payment of such additional amounts.
