Regardless of whether the Township or any duly constituted Township board, agency or department is acting in or pursuant to the performance of a governmental or proprietary function, any municipally owned, operated or controlled building, structure, facility or use, either existing or proposed, shall be permitted in any class of zone as set forth in this chapter, it being the intention of this section that whatever the Township may authorize to do shall constitute a function of government and that whenever the Township shall act pursuant to granted authority, it acts as government and not as a private entrepreneur.
