Notwithstanding any other provision of this chapter, it is the intent of the Legislature that the rate of taxes levied annually upon the property in a school facilities improvement district formed pursuant to subdivision (a) of Section 15301 not be greater than the rate of the annual special tax levied upon parcels in the same school district or community college district that are part of a community facilities district formed pursuant to the Mello-Roos Community Facilities Act of 1982, as set forth in Chapter 2.5 (commencing with Section 53311) of Part 1 of Division 2 of Title 5 of the Government Code that has as one of its purposes the construction of school facilities within a portion of the territory of the school district or community college district. A determination by the governing board of a school district or community college district, made at the time bonds are sold pursuant to this part, that the rate of taxes to be levied annually upon the property in the school facilities improvement district, based upon tax rate estimates prepared pursuant to Section 9401 of the Elections Code, does not exceed the rate of the annual special tax levied upon parcels in the same school district or community college district that are part of a community facilities district formed pursuant to the Mello-Roos Community Facilities Act of 1982, shall be conclusive evidence of compliance with the intent of this section.
