Section 11.6 Budget Control.
   At the beginning of each quarterly period during the fiscal year, and more often if required by the Council, the City Manager shall submit to the Council 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 Council 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.
