Upon the request of all of the owners of record to be subject to assessment in a special assessment proceeding, the alternative procedure for the proceeding set forth in this Section may be used. In this alternative procedure, the board of local improvements shall conduct all of the proceedings and perform all of the acts otherwise performed by the court. There shall be no right to jury trial or any reference to the rules of civil procedure applicable to the court, but the board of local improvements shall conduct its proceedings with due notice, fairly and impartially. Determinations of the board of local improvements shall be treated as the determination of an administrative agency and shall be subject to appeal under the same procedures as an appeal of an administrative decision of an administrative agency under the Administrative Review Law.
