CA Health & Safety Code Section 6480.7

If a consolidation involving the Capistrano Beach Sanitary District and the Dana Point Sanitary District is approved, the board of directors of the consolidated district shall initially consist of 10 members who shall be the members of the boards of directors of the two districts as of the effective date of the consolidation. Notwithstanding Section 56844 of the Government Code, those board members shall determine within 60 days from the effective date of the consolidation whether the board of directors shall consist of 5, 7, 9, or 11 members, and they shall further determine within that time the persons who shall thereafter be members of the board of directors. If those board members determine that the board of directors shall consist of 11 members, they shall appoint the eleventh member whose term shall be the same as the terms of the members of the board of directors whose terms will first expire. Upon making those determinations, the members so selected shall notify by resolution the Board of Supervisors and the Registrar of Voters of the County of Orange of the number of members and the names of the persons who have been selected or appointed as members of the board of directors, and of the expiration dates of their terms of office. If that selection and appointment process is not completed within 60 days of the effective date of the consolidation, the Board of Supervisors of the County of Orange shall determine the number of members of the board of directors and shall select the members of the board of directors from among those 10 persons, or call a special election for the election of the directors of the consolidated district on the next available election date. In that event, those 10 persons shall serve as the board of directors until the results of the special election are declared by the board of supervisors.
