All actions by the governing and administrative body shall be by ordinance or resolution by the affirmative vote of a majority of the city councils of the participating municipalities. However, the governing and administrative body may not take any action solely within one participating municipality without the approval of the majority of members on that participating municipality's city council. If an ordinance or resolution adopted by the governing and administrative body conflicts with an ordinance or resolution relating to Port District purposes adopted of a city council of a participating municipality, the ordinance or resolution adopted by the city council of the participating municipality controls unless the majority of members on that participating municipality's city council approved the ordinance or resolution of the governing and administrative body.
All ordinances, resolutions, and proceedings of the city council of a participating municipality and all documents and records in its possession are public records and open to public inspection at the office of the participating municipality, except documents and records that are kept or prepared by the participating municipality for the Port District within the municipality's corporate limits for use in negotiations, legal actions, or proceedings related to that portion of the Port District within the municipality's corporate limits.
