The procedure upon the election shall be in accordance, so far as applicable, with the procedure upon an original issue of bonds, except that:
(a) No hearing need be held upon the question whether the bond issue will benefit the entire district or only a portion of it.
(b) A vote of two-thirds of the voters voting upon the measure is sufficient to authorize the issue of refunding bonds.
