The council shall have the power and it is hereby authorized to provide by resolution,
at one time or from time to time in series, for the issuance of bonds of the county
for the purpose of paying all or part of the costs of a project. The principal of
and interest on each series of bonds shall be payable from pledged revenues. At the
option of the council, the county may covenant to budget and appropriate in any fiscal
year from non-ad valorem revenue sources identified by the county by resolution or
from general non-ad valorem revenues of the county an amount necessary to make up
any deficiency in the payment of the bonds. The county may issue a single series of
bonds to finance projects in different special assessment districts, provided such
resolution identifies each project to be financed and the special assessment district
in which it is located.
