The board may approve, in whole or in part, an application submitted by a school district under

Section and in the amount, not exceeding the amount applied for, that the board may deem appropriate. The board may, upon approval of the application, in whole or in part, and subsequently from time to time, make a conditional apportionment or conditional apportionments not exceeding in the aggregate the total amount determined by the board as aforesaid, to the applicant school district from the Public School Building Loan Fund for that portion or portions of the project that the board determines the district is ready to proceed with.

If the board has approved an application and made an apportionment as to a portion or portions of a project, the board may approve the remaining portion or portions of the project and make an additional apportionment or apportionments within two years after the original approval without requiring a district to issue additional bonds. The total of the amounts of applications as approved by the board under this

section shall not, when added to all amounts apportioned to school districts by the board under

Section 15713, exceed percent of the total amount of state school building bonds authorized to be issued and sold by

Section of

Article XVI of the Constitution of the state. Except as otherwise provided in this section, all provisions of this

chapter relating to apportionments shall apply to apportionments made under this section. Approval of an application under this

section shall not be construed as creating or implying any obligation, commitment or promise on the part of the board or the state to make apportionments under this chapter.
