(a) A borough may incur indebtedness on
(1) an areawide basis for areawide functions; or
(2) a nonareawide basis for functions performed only in the borough area outside all cities; or
(3) a service area basis for functions performed only in a service area.
(b) Payment of debt principal and interest as well as other costs shall be derived from the area incurring the debt under (a)(2) or (a)(3) of this section, except that the full faith and credit of the entire borough may be pledged to guarantee payment of principal and interest.
(c) If the bonded debt to be incurred by a borough is an areawide debt, the vote is areawide. If the full faith and credit of the entire borough is pledged for the payment of the debt of the borough area outside all cities or of a service area, an areawide election is held and the proposition must pass both areawide and in the area that will benefit from the improvement. If the bonded indebtedness to be incurred is limited to the borough area outside all cities, the vote is limited to voters outside all cities.

Only the full faith and credit of the area voting on the indebtedness is pledged for the payment of the debt.
(d) The indebtedness of a municipality reclassified under AS 29.04.040 - 29.04.060 is not affected by reclassification.
