Pursuant to RCW 9.41.300(2), the Pierce County Council may designate certain areas of Pierce County where the discharge of firearms shall be prohibited or restricted. Citizens may petition the County Council for the formation, dissolution or amendment of an area where the discharge of firearms shall be prohibited or restricted or the Council may initiate the creation, dissolution or amendment of such an area by passing a resolution declaring its intent to do so. Under no circumstances shall the County Council designate a prohibited or restricted area until the Firearms Advisory Commission, created pursuant to Chapter 2.79 of the Pierce County Code, has had an opportunity to review the proposal and make its recommendation to the Council. No single proposal for an area where the discharge of firearms shall be prohibited or restricted may exceed 160 acres.
