Such annual appropriation bill may be amended at the next meeting of the board of commissioners, occurring not less than five days after the passage thereof, in like manner as other resolutions appropriating money. Such ordinance, as originally passed or as subsequently amended, may also be amended, at any meeting of the board of commissioners held not more than 15 days after the first meeting of such board of commissioners occurring not less than 5 days after the passage of such annual appropriation bill, by repealing or reducing the amount of any item or items of appropriation contained therein. The board of commissioners has the power, by a two-thirds vote of all members of such body, to make transfers within any fund, department or other office or agency of the county, of sums of money appropriated for one corporate object or purpose to another corporate object or purpose, but no appropriation for any object or purpose shall thereby be reduced below an amount sufficient to cover all obligations incurred against such appropriation.
For purposes of controlling expenditures, the expenditure of or incurring of obligations against any appropriation may be delayed, restricted, or terminated with regard to any object or purpose for which appropriations were made in the appropriation bill or resolution. A monthly schedule for the year of proposed expenditure, including any limitations or conditions against appropriations for each program, subactivity, and the agency or department, shall be made within 30 days of the adoption of the annual appropriation bill, and such schedule, as amended by the President of the County Board, shall be binding upon all officers, agencies, and departments, and such schedule of expenditure or of incurring obligations may not be exceeded, provided that any such schedule may be revised after three calendar months have elapsed since the last schedule.
