The City Council may revise, alter, increase or decrease the
items contained in the proposed budget, subject to such limitations
as may be provided by law; provided, that in no event shall the total
authorized expenditures from any fund exceed the estimated revenues
to be received plus any unencumbered balance or less any deficit estimated
for the beginning of the budget year. Except as otherwise provided
by law, the City Council shall, before the beginning of the fiscal
year, approve the budget and approve or adopt such orders, motions,
resolutions or ordinances as may be required to authorize the budgeted
expenditures and produce the revenues estimated in the budget.
The budget or any authorization to expend funds shall be approved
by an ordinance, motion or resolution that is approved by a majority
of all the members elected to the City Council.
