Where the governing body, in the Zoning Ordinance, has stated conditional uses to be granted or denied by the governing body pursuant to express standards and criteria, the governing body shall hold hearings on and decide requests for such conditional uses in accordance with such standards and criteria. The hearing shall be conducted by the Board or the Board may appoint any member or an independent attorney as a hearing officer. The decision, or, where no decision is called for, the findings shall be made by the Board. However, the appellant or the applicant, as the case may be, in addition to the Tinicum Township, may, prior to the decision of the hearing, waive decision or findings by the Board and accept the decision or findings of the hearing officer as final. In granting a conditional use, the Board may attach such reasonable conditions and safeguards, in addition to those expressed in the ordinance, as it may deem necessary to implement the purposes of this act in the Zoning Ordinance.
