(1) All powers or duties prescribed for or conferred on any particular officer, official, board, commission or other official entity by statute.
(2) All powers or duties expressly prescribed by or conferred thereon by a provision of this code.
(3) All powers or duties implied by the nature of and necessary or dispensable for the proper and efficient fulfillment of their governmental or corporate function or duties of office, including, but not necessarily limited to, the power to prescribe administrative rules or procedures for the governance of their respective offices, departments, agencies or functions to the extent not inconsistent with nor preempted by a provision of this code or a statute, or by an applicable and mandatory state or federal administrative regulation.
(B) To the extent provided by this section, the fact that a particular power or duty is not expressly set forth in this code and conferred on an officer, official, board, commission or other official entity does not, of itself, imply that the power or duty does not exist or has been considerately denied or withheld.
