No ordinance for any local improvement, to be paid wholly or in part by special assessment or special taxation, shall be considered or passed by the corporate authorities of any such municipality unless the ordinance is first recommended by the board of local improvements; provided, however, that after the ordinance for any local improvement has been adopted by the corporate authorities and before the same is confirmed in court, the corporate authorities, upon recommendation of the board of local improvements, may by ordinance abandon any portion of the proposed improvement without further action by or hearing before the board.
