In not less than 12 months, nor more than 13 months after the recording of the certificates of incorporation, a meeting shall be held for the election of directors. Each director shall be elected for a term of four years and until a successor is elected and qualified. Notice of the meeting shall be given at least 10 days prior to the date thereof by one publication in a newspaper of general circulation in each of the counties of which the district is a part. Elections shall be by ballot. Qualified voters shall be entitled to vote at any such meeting. The directors shall fill any vacancy occurring on the board prior to the expiration of the term of any director by electing a substitute director to serve for the unexpired term. All elections, except the first, shall be held on the first Tuesday in April and every four years thereafter.

The directors shall meet at least once each year. Notice of the annual meeting shall be given at least 10 days prior to the meeting by one publication in a newspaper of general circulation in each of the counties of which the district is a part. The number of directors of a district or the date of the annual meeting, or both, may be changed at an annual meeting if notice of the proposition of making the change or changes are given at the annual meeting immediately preceding the annual meeting at which the change or changes are considered.
