The regulations shall provide the conditions under which the extensions shall be made to render compensatory and shall provide that each extension project shall, when completed, become the property of the city whether on public or private property. The council may provide for the form of refunds where advances by the persons benefitted are necessary to make extensions compensatory. (Ord. 1988-1: prior code § 14-511.3)
