In those areas zoned industrial, all utility service lines for any utility service to any lot from the distribution line of the utility in any street or easement area shall be underground, including, but not limited to, electricity, gas, water, telephone and cable TV. The provisions hereof shall apply notwithstanding whether said distribution lines in the public streets or other easements are or are not underground, but as to existing developed properties already having the particular utility service, the requirements of this section shall apply only when and as there is an addition of building area of twenty-five percent (25%) or more, or the requirement is otherwise imposed pursuant to other provisions of law or ordinance.
