Where bids have been advertised for projects that would use funds allocated to any county maintenance district for a particular fiscal year but because of the bidding process the contract or contracts were not awarded before the close of that fiscal year, the county's allocation for that fiscal year shall not lapse but may be allocated to the particular contract that was not awarded because of the incompleteness of the bidding process. Any additional allocation remaining after all such contracts are let shall lapse as of the date of the awarding of the last of the contracts.
