(a) Following each decennial federal census, and using population figures as validated by the Demographic Research Unit of the Department of Finance as a basis, the governing board of each school district or community college district in which trustee areas have been established, and in which each trustee is elected by the residents of the area the trustee represents, shall adjust the boundaries of any or all of the trustee areas of the district so that one or both of the following conditions is satisfied:

(1) The population of each area is, as nearly as may be, the same proportion of the total population of the district as the ratio that the number of governing board members elected from the area bears to the total number of members of the governing board.

(2) The population of each area is, as nearly as may be, the same proportion of the total population of the district as each of the other areas.

(b) The boundaries of the trustee areas shall be adjusted by the governing board of each school district or community college district, in accordance with subdivision (a), before the first day of March of the year following the year in which the results of each decennial census are released. If the governing board fails to adjust the boundaries before the first day of March of the year following the year in which the results of each decennial census are released, the county committee on school district organization shall do so before the 30th day of April of the same year.

The governing board of the school district or community college district shall reimburse all reasonable costs incurred by a county committee in adjusting the boundaries pursuant to this subdivision.

(c) Except to the extent that the adjustment of trustee area boundaries is necessary for the purposes set forth in this section, the authority to establish or abolish trustee areas, rearrange the boundaries of trustee areas, increase or decrease the number of members of the governing board, or adopt any method of electing governing board members may be exercised only as otherwise provided under this article.
