(a) (1) The board of education of a school district to which the provisions of this section apply may levy an ad valorem tax on the taxable tangible property of the school district each year for a period of time not to exceed two years in an amount not to exceed the amount authorized by the state board of tax appeals under this subsection for the purpose of financing the costs incurred by the state that are directly attributable to assignment of ancillary school facilities weighting to the enrollment of the school district. The state board of tax appeals may authorize the school district to make a levy that will produce an amount that is not greater than the difference between the amount of costs directly attributable to commencing operation of one or more new school facilities and the amount that is financed from any other source provided by law for such purpose. If the school district is not eligible, or will be ineligible, for ancillary school facilities weighting in any one or more years during the two-year period for which the school district is authorized to levy a tax under this subsection, the state board of tax appeals may authorize the school district to make a levy, in such year or years of ineligibility, that will produce an amount that is not greater than the actual amount of costs attributable to commencing operation of the facility or facilities.

(2) The state board of tax appeals shall certify to the state board the amount authorized to be produced by the levy of a tax under this subsection.

(3) The state board of tax appeals may adopt rules and regulations necessary to effectuate the provisions of this subsection, including rules and regulations relating to the evidence required in support of a school district’s claim that the costs attributable to commencing operation of one or more new school facilities are in excess of the amount that is financed from any other source provided by law for such purpose.

(b) The board of education of a school district that has levied an ad valorem tax on the taxable tangible property of the school district each year for a period of two years under authority of subsection (a) may continue to levy such tax under authority of this subsection each year for an additional period of time not to exceed six years in an amount not to exceed the amount computed by the state board as provided in this subsection if the board of the school district determines that the costs attributable to commencing operation of one or more new school facilities are significantly greater than the costs attributable to the operation of other school facilities in the school district. The tax authorized under this subsection may be levied at a rate that will produce an amount that is not greater than the amount computed by the state board as provided in this subsection. In computing such amount, the state board shall:

(1) Determine the amount produced by the tax levied by the school district under authority of subsection (a) in the second year for which such tax was levied and add to such amount the amount of state foundation aid directly attributable to ancillary school facilities weighting that was received by the school district in the same year;

(2) compute 90% of the amount of the sum obtained under subsection (b)(1), which computed amount is the amount the school district may levy in the first year of the six-year period for which the school district may levy a tax under authority of this subsection;

(3) compute 75% of the amount of the sum obtained under subsection (b)(1), which computed amount is the amount the school district may levy in the second year of the six-year period for which the school district may levy a tax under authority of this subsection;

(4) compute 60% of the amount of the sum obtained under subsection (b)(1), which computed amount is the amount the school district may levy in the third year of the six-year period for which the school district may levy a tax under authority of this subsection;

(5) compute 45% of the amount of the sum obtained under subsection (b)(1), which computed amount is the amount the school district may levy in the fourth year of the six-year period for which the school district may levy a tax under authority of this subsection;

(6) compute 30% of the amount of the sum obtained under subsection (b)(1), which computed amount is the amount the school district may levy in the fifth year of the six-year period for which the school district may levy a tax under authority of this subsection; and

(7) compute 15% of the amount of the sum obtained under subsection (b)(1), which computed amount is the amount the school district may levy in the sixth year of the six-year period for which the school district may levy a tax under authority of this subsection.

In determining the amount produced by the tax levied by the school district under authority of subsection (a), the state board shall include any moneys apportioned to the ancillary school facilities fund of the school district from taxes levied under the provisions of Kan. Stat. Ann. § 79-5101 et seq. and 79-5118 et seq., and amendments thereto.

(c) The proceeds from any tax levied by a school district under authority of this section shall be remitted to the state treasurer in accordance with the provisions of Kan. Stat. Ann. § 75-4215, and amendments thereto. Upon receipt of each such remittance, the state treasurer shall deposit the entire amount in the state treasury to the credit of the state school district finance fund.

(d) The ancillary school facilities weighting may be assigned to the enrollment of a school district only if the school district has levied a tax under the authority of subsection (a), and remitted the proceeds from such tax to the state treasurer. The ancillary school facilities weighting of each school district shall be determined in each school year in which such weighting may be assigned to the enrollment of the school district as follows:

(1) Add the amount to be produced by a tax levy as authorized under subsection (a) and certified to the state board by the state board of tax appeals to the amount computed under subsection (b) to be produced by a tax levy, if any; and

(2) divide the sum obtained under subsection (d)(1) by the BASE aid. The resulting quotient is the ancillary school facilities weighting of the school district.

(e) The provisions of this section apply to any school district that:

(1) Commenced operation of one or more new school facilities in the school year preceding the current school year or has commenced or will commence operation of one or more new school facilities in the current school year;

(2) adopted a local option budget; and

(3) is experiencing extraordinary enrollment growth as determined by the state board.
