If the participating localities are of the opinion that the facts stated in the authority's resolution are true and the authority should be dissolved, they shall so resolve and the authority shall stand dissolved as of the date on which the last participating locality adopts such resolution. Upon such dissolution, the title to all funds and properties owned by the authority at the time of such dissolution shall vest in the participating localities.
