Prior to the third public meeting of council preceding the end of the county's fiscal
year, the county administrator shall introduce for the first reading an appropriation
ordinance which shall set forth in detail appropriations for all county purposes and
activities during the ensuing fiscal year; and this article, as it may be amended,
shall be enacted by the council prior to the commencement of such fiscal year. The
total of the appropriations under such ordinance shall not exceed the total of anticipated
county revenue from all sources as projected. Such appropriations ordinance shall
include a contingency fund, to cover items of expenditure for which express provision
has not been made elsewhere in the ordinance.
