The board is hereby authorized to levy a tax of not to exceed one mill on all the taxable tangible property within the jurisdiction of the board for the purpose of paying the contribution to be made by the board to the supplemental retirement fund and for the purpose of paying a portion of the principal and interest on bonds issued by cities under the authority of Kan. Stat. Ann. § 12-1774, and amendments thereto, for the financing of redevelopment projects upon property located within the school district. If in any year such levy does not raise sufficient money to make the contribution required, any deficiency may be made up in subsequent years, so long as the levy in any year does not exceed one mill. Such levy shall be in addition to all other levies authorized or limited by law and none of the levy limitations of article 19 of chapter 79 of the Kansas Statutes Annotated shall apply to such levy.
