Idaho Code § 70-1607
A port district may formulate all needful regulations for the use by tenants, agents, servants, licensees, invitees, suppliers, passengers, customers, shippers, business visitors and members of the general public, of any properties or facilities owned or operated by it, and request the adoption, amendment or repeal of such regulations as part of the ordinances of the city in which such properties or facilities are situated, or as a part of the resolutions of the county, if such properties or facilities be situated outside any city. The port commission shall make such request by resolution after holding a public hearing on the proposed regulations, notice of which shall be published in a legal newspaper of general circulation in the port district by one (1) publication at least ten (10) days prior to such hearing. In such notice the proposed regulation may be stated in general terms. Such regulations must conform to and be consistent with federal and state law. As to properties or facilities situated within a city, such regulations must conform to and be consistent with the ordinances of the city. As to properties or facilities situated outside any city, such regulations must conform to and be consistent with county ordinances or resolutions. Upon receiving such request, the governing body of the city or county as the case may be, may adopt such regulations as part of its ordinances or resolutions or amend or repeal such regulations in accordance with the terms of the request. Such regulations may be amended or repealed in the same manner as they are adopted. Such regulations shall be compiled and shall be a matter of public record. When any such regulation shall so specify, any violation thereof shall constitute a misdemeanor which shall be redressed in the same manner as other municipal police regulations, and it shall be the duty of all law enforcement officers to enforce such regulations accordingly.
