(a) A school district or community college district that has 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, may proceed under this chapter. (b) The boundaries of a school facilities improvement district formed pursuant to this chapter shall include all of the portion of the territory within the boundaries of the school district or community college district that is not located within the boundaries of the community facilities district as described in subdivision (a). (c) A school district or community college district may proceed under this chapter without meeting the requirements of subdivisions (a) and (b) if the governing board of the school district or community college district determines that it is necessary and in the best interest of the school district or community college district, respectively, to form a school facilities improvement district pursuant to this chapter to finance school facilities and purposes authorized pursuant to Section 15100. As a part of that determination, the governing board of the school district or community college district shall make a finding that the overall cost of financing the bonds issued pursuant to this part would be less than the overall cost of other school facilities financing options available to the school district or community college district, including, but not limited to, issuing bonds pursuant to the Mello-Roos Communities Facilities Act of 1982 (Ch. 2.5 (commencing with Sec. 53311), Pt. 1, Div. 2, Title 5, Gov. C.). The governing board of the school district or community college district proceeding under this subdivision shall define the boundaries of the school facilities improvement district to include any portion of territory within the jurisdiction of the school district or community college district. (d) The governing body of a school district or community college district that proceeds under this chapter shall comply with the filing requirements established by Section 54902 of the Government Code. A plat or map that is filed pursuant to this subdivision shall specifically identify property, located within the school district or community college district, that is not located within the improvement district established by the school district or community college district pursuant to this chapter.
