Regardless of whether the City is acting in or pursuant to the performance of a governmental function carrying out a legislative mandate or in the exercise of its private right as a corporate body, any municipality owned, operated or controlled building, structure, facility or use, either existing or proposed, shall be permitted in any class of zone; it being the intention that whatever the City may be authorized to do, shall constitute a function of government and that whenever the City shall act pursuant to granted authority, it acts as government and not as a private entrepreneur. Further, the City shall submit development plans to the Planning Board but shall not pay to itself application fees.
