Plans and recommendations may include a provision specifying that the election for the first governing board will be held at the same time as the election on the reorganization of the school districts. If such a provision is included, it shall specify the method whereby the length of the initial terms may be determined so that the governing board will ultimately have staggered terms which expire in years with regular election dates. In the absence of such a provision, the election of the first governing board will take place on the first regular election following the passage of the reorganization proposal.
