Cal. Ed. Code § 5203.6
If the Charter of the City of San Leandro is amended so that it no longer provides for a board of education of the San Leandro Unified School District, a new board of education composed of seven members is created under this section immediately upon the effective date of such amendment. The San Leandro Unified School District shall be divided into six trustee areas as had been provided in the Charter of the City of San Leandro, and the members thereof shall be elected in the same manner as provided in the Charter of the City of San Leandro, before the effective date of such amendment. The members of the board in office on the effective date of the charter amendments shall each continue in office until the first day of April, or until a successor qualifies therefor, in the year in which their respective term of office would otherwise have terminated.
