The budget shall reflect as nearly as possible the estimated revenues and expenditures for the year for which the budget is prepared. Upon adopting the budget, the county commissioners shall:
(1) adopt the appropriation measures required to put the budget into effect; and
(2) fix the rate of taxation upon the valuation of the property taxable for county purposes that, together with the other estimated revenues of the county, excluding operating, capital and other reserve funds, raise a sufficient sum to meet the expenditures.
