1. Except as prohibited, limited or preempted by the Constitution, statutes or regulations of the United States or this State and except as otherwise provided in this section, a board of county commissioners has:

(a) All powers expressly granted to the board;

(b) All powers necessarily or fairly implied in or incident to the powers expressly granted to the board; and

(c) All other powers necessary or proper to address matters of local concern for the effective operation of county government, whether or not the powers are expressly granted to the board.
