Any ordinance passed, adopted or otherwise enacted by the board shall before it becomes effective be presented to the county executive. If the county executive approves such ordinance, resolution or motion, the county executive shall sign it; if not, the county executive shall return it to the board with the objections, which shall be entered and spread upon the journal, and the board shall proceed to reconsider the matter. If after such reconsideration 3/5 of the members of the board pass such ordinance, it shall become effective on the date prescribed but not earlier than the date of passage following reconsideration. In all such cases the votes of the members of the board shall be determined by yeas and nays and the names of the members voting for or against such ordinance objected to by the county executive shall be entered and spread upon the journal. If any ordinance is not returned by the county executive to the board at its first meeting occurring not less than 6 days, Sundays excepted, after it has been presented to the county executive, it shall become effective unless the board has recessed or adjourned for a period in excess of 60 days, in which case it shall not become effective without the approval of the county executive. Items of appropriation may be approved or vetoed by the county executive. Any item approved by the county executive and all items not vetoed shall become law, and any item vetoed shall be returned to and reconsidered by the board in the same manner as provided in this Section for other ordinances returned to the board without approval.
