After the public hearing on the tentative budget, the city council may continue to review the tentative budget and may insert new items or increase or decrease items of expenditures that were the proper subject of consideration at the public hearing; provided, that no appropriation required for debt retirement and interest, reduction of any existing deficits, or otherwise required by law or ordinance, may be reduced below the minimum required. The city council shall increase or decrease the total anticipated revenue to equal the net change in proposed expenditures in the budget of each fund. (Ord. 2012-30, 10-2-2012)
