(2) For the cost of operation by the County of park and recreational facilities which are not local in nature and which serve the metropolitan area.
(3) To any municipality not expending funds in the previous fiscal year for the given local service function or not adequately performing the local service function.
(e) The Chief Administrative Officer and the County Executive, in the preparation of the annual operating budget, shall divide and segregate in a separate budget entitled General Operating Budget all appropriations not properly allocable to the Local Service Function Budget or other operating budget fund.
