If, after any such public hearing the Council finds that the public necessity, health, safety or welfare requires the removal and the underground installation within a designated area, the Council shall, by resolution, declare the designated area an underground utility district and order such removal and underground installation. The resolution shall include a description of the area comprising the district and shall fix the time within which the removed and underground installation shall be accomplished and within which affected property owners must be ready to receive underground service. A reasonable time shall be allowed for the removal and underground installation, having due regard for the availability of labor, materials, and equipment necessary for the removal and for the installation of the underground facilities as may be occasioned thereby.
