Section 8.7 Budget Control:
   At the beginning of each quarterly period during the fiscal year, and more often if required by the Commission, the City Manager shall submit to the Commission data showing the relation between the estimated and actual income and expenses to date; and if it shall appear that the income is less than anticipated, the Commission may reduce appropriations, except amounts required for debt and interest charges, to such a degree as may be necessary to keep expenditures within the cash income.
