If from the canvass it appears and the board of supervisors finds that a majority of the votes were cast in favor of the formation of the district, it shall enter that fact upon its minutes, together with a description of the boundaries of the district, its name, the official name or names by which the district is commonly known and enter its order declaring the district duly formed and existing in the county in which the proceedings were had. The board of supervisors shall also make an order declaring the five candidates for harbor commissioner receiving the highest number of votes to have been elected to such office and cause a certificate of election to be issued to the successful candidates.
