Notwithstanding Section 11908, the board of a district which has owned and operated an electric distribution system for at least eight years and has a population of 250,000 or more may provide, by ordinance or resolution, that each director shall receive compensation in an amount not to exceed one hundred dollars ($100) per day for each day’s attendance at public meetings of the board or for each day’s service rendered as a director by request of the board, not exceeding a total of 10 days in any calendar month, together with any expenses incurred in the performance of his or her duties required or authorized by the board. The board may, by resolution or ordinance, increase the compensation per day by not more than 5 percent for each calendar year following the operative date of the last adjustment, commencing with the 1988 calendar year. No resolution or ordinance establishing compensation pursuant to this subdivision shall provide for any automatic increase in that compensation. For purposes of this section, the determination of whether a director’s activities on any specific day are compensable shall be made pursuant to Article 2.3 (commencing with Section 53232) of Chapter 2 of Part 1 of Division 2 of Title 5 of the Government Code. Reimbursement for these expenses is subject to Sections 53232.2 and 53232.3 of the Government Code.
