The Board shall render a decision not later than 120 days after the date an appeal is taken. In its decision, the Board may reverse or affirm wholly or in part or modify the action, order, requirement, interpretation or determination of the original decisions. An appeal to the Board shall stay all proceedings in furtherance of the action in respect to which the decision appealed from was made unless the officer from whose section the appeal is taken certifies to the Board, after filing of the appeal, that by reason of facts stated in the certificate, a stay would, in his or her opinion, cause imminent peril to life or property. In such case, proceedings shall not be stayed other than by an order of the Superior Court.
