Cal. Ed. Code § 16059
Notwithstanding any provision of Section 16058, if a previously eligible applicant school district has received apportionments and has realized savings in state aid apportionments or district contributions, or both, including any interest earned thereon, on completed projects pursuant to this chapter, which projects have not been reduced to final costs, the district may apply for, and shall be granted, final apportionments for additional eligible facilities in a total amount not to exceed those project savings.
The project savings for which a district has applied pursuant to this section shall not be considered excess apportionments or unencumbered balances for the purposes of Sections 16100 and 16104.
In no event shall the grant of the project savings to the district pursuant to this section extend the repayment period of any prior apportionments for the purposes of canceling the interest and principal payable thereon pursuant to Section 16083.
