Vacancies On The Board Of Trustees. Where the provisions of a trust indenture cannot be fulfilled by reason of unfilled vacancies among the trustees, the City Council may, upon the petition of any concerned resident or property owner of the subdivision, appoint one (1) or more trustees to fill vacancies until such time as trustees are selected in accordance with the trust indenture. Any person so appointed who is not a resident or property owner within the subdivision shall be allowed a reasonable fee for his/her services by the order of appointment, which fee shall be levied as a special assessment against the property in the subdivision and which shall not be subject to any limitations on special assessments contained in the trust indenture or elsewhere.
