The following exceptions to the strict applicability of this subchapter shall be allowed upon the conditions stated.
(A) Transmission lines. Above-ground placement, construction, modification or replacement of those lines commonly referred to as "high voltage transmission lines" upon which the conductor's normal operating voltage equals or exceeds 23,000 volts (phase to phase) shall be allowed; provided, however, that 60 days prior to commencement of construction of a project, the city shall be furnished notice of the proposed project and, upon request, the utility company involved shall furnish any relevant information regarding the project to the city. This section shall not be construed as waiving the requirements of any other ordinance or regulation of the city as the same may apply to any proposed project.
(B) Technical and economic feasibility. Above-ground placement, construction, modification or replacement of lines shall be allowed in residential, commercial and industrial areas where the Council, following consideration and recommendation by the Planning Commission, finds that:
(1) Underground placement would place an undue financial burden upon the landowner or the utility company or deprive the landowner of the preservation and enjoyment of substantial property rights; or
(2) Underground placement is impractical or not technically feasible due to topographical, subsoil or other existing conditions which adversely affect underground utility placement.
(C) Temporary service. Above-ground placement of temporary service lines shall only be allowed:
(1) During the new construction of any project for a period not to exceed 24 months;
(2) During any emergency to safeguard lives or property within the city; or
(3) For a period of not more than seven months when soil conditions make excavation impractical.
