Cal. EDC § 15725

No apportionment shall be made to a school district for any grade level if the estimated cost of the project, as approved by the Director of General Services, is (1) an amount which would result in an apportionment to the district exceeding the amount authorized at the district election held under Section 15721, or (2) an amount which if raised by the issuance and sale of bonds of the district running for 25 years bearing the current going rate of interest as determined by the board and the principal of which is payable in 25 equal annual payments, would require the levy of a tax under Section 15250 upon property in the district which would, when added to the tax actually being levied upon property in the district for the grade level as determined by the Director of General Services under that section, amount to less than thirty cents ($0.30) on each one hundred dollars ($100) of assessed valuation of property in the district during the next fiscal year. Beginning in 1981–82, the amount shall be the levy of a tax which would amount to less than 0.075 percent of full valuation of property in the district during the next fiscal year.

At the time the board makes an apportionment, it shall, with the approval of the Director of General Services, fix the interest to be paid by the district on the sum apportioned to it at a rate equal to the effective rate paid by the state upon the bonds sold from the proceeds of which the apportionment is made, giving effect to the price at which the bonds are sold and the premium, if any, paid thereon, adjusted to the next highest one-eighth of 1 percent, to cover the cost of sale and issuance of the bonds and costs of administration, to be compounded annually through the 30th day of June of each year.
