(1) Except as provided in subsection (2) of this section, the board shall determine in each year the amount of money necessary to be raised by taxation, taking into consideration other sources of revenue of the special district, and shall fix a rate of levy which, when levied upon every dollar of valuation for assessment of taxable property within the special district and together with other revenues, will raise the amount required by the special district annually to supply funds for paying expenses of organization and the costs of constructing, operating, and maintaining the facilities and improvements of the special district and to pay in full, promptly, when due, all interest on and principal of bonds and other obligations of the special district. In the event of accruing defaults or deficiencies, an additional levy may be made as provided in subsection (2) of this section.

(2) The board, in certifying annual levies, shall take into account the maturing indebtedness for the ensuing year as provided in its contracts, maturing bonds and interest on bonds, and deficiencies and defaults of prior years and shall make ample provision for the payment thereof. If the moneys produced from such levies, together with other revenues of the special district, are not sufficient to pay punctually the annual installments on its contracts or bonds, and interest thereon, and to pay defaults and deficiencies, the board shall make such additional levies of taxes as may be necessary for such purposes, and, notwithstanding any limitation provided in part 11 of this article, such taxes shall be made and continue to be levied until the indebtedness of the district is fully paid.

(3) In accordance with the schedule prescribed by section 39-5-128, C.R.S., the board shall certify to the board of county commissioners of each county within the special district, or having a portion of its territory within the district, the rate so fixed in order that, at the time and in the manner required by law for the levying of taxes, such board of county commissioners shall levy such tax upon the valuation for assessment of all taxable property within the special district. When necessary, a special district shall, with respect to an increased mill levy, comply with the requirements of part 3 of article 1 of title 29, C.R.S.
