Pursuant to that legislative direction, the committee shall determine whether or not it is necessary or desirable to issue bonds authorized pursuant to this chapter in order to carry out the purposes described in this chapter and, if so, the amount of bonds to be issued and sold. Successive issues of bonds may be authorized and sold to carry out those actions progressively, and it is not necessary that all of the bonds authorized to be issued be sold at any one time.
