Upon request of the State Allocation Board from time to time, supported by a statement of the apportionments made and to be made for the purposes described in Sections 100615 and 100620, the State School Building Finance Committee shall determine whether or not it is necessary or desirable to issue bonds authorized pursuant to this chapter in order to fund the apportionments and, if so, the amount of bonds to be issued and sold. Successive issues of bonds may be authorized and sold to fund those apportionments progressively, and it is not necessary that all of the bonds authorized to be issued be sold at any one time.
