The governing board of any school district or community college district may petition the board of supervisors to cancel the remaining authorization of that district to issue and sell bonds resulting from any particular school bond election after the sale of at least 90 percent of the bonds authorized at the election if the amount of the remaining authorization is not more than twenty-five thousand dollars ($25,000) and in the opinion of the governing board the sale of the remaining bonds would not be economically justified. Sections 15201 and 15202 shall be applicable and at or following, the hearing provided in Section 15201 and 15202, the board of supervisors, if it determines that the public interest will be served thereby, may make and enter an order in the minutes of its proceedings that the remaining authorization be canceled. Upon the entry of the order the vote by which the remaining authorization was created shall cease to be of any validity with respect to the remaining authorization.
