(c) The city's legislative body may refund bonds sold under this section with other bond issues in accordance with section 5 and other provisions of this chapter relating to the sale of bonds.  The city's legislative body may name the date when the first series of refunding bonds is due.  However, the due date of the first series due may not be more than five (5) years from the date of issue.
