At the time of filing a petition to amend or change the ordinance, the petitioner shall submit a fee in an amount as then currently established by resolution of the Board of Supervisors. The fee is established to reimburse the Township for costs incurred by the Township in connection with the petitioner's hearing before the Board of Supervisors. Such costs may include a shared appearance fee for a stenographer, notice for advertising costs and necessary administrative overhead connected with the hearing. The costs, however, may not include legal, engineering, architectural or other technical consultants or expert witnesses. Upon completion of the hearing, the petitioner shall be billed for expenses in excess of the deposit, if any. No permit or other activity may be granted to, or allowed to proceed for, the petitioner until such expenses are reimbursed to the Township in full. Any fee hereunder shall be nonrefundable.
