At any regular or special meeting the board may cancel any appropriation in whole or in part that is not needed and transfer the amount canceled to the appropriation for contingencies of the fund from which the appropriation was originally made if there is one, or to any appropriation for contingencies account, or fund, to which the amount canceled may be properly transferred. If there is no appropriation for contingencies in the respective fund, the board may establish one.
