Subject to the applicable provisions of statute and this charter, the Commission may by ordinance or resolution authorize the borrowing of money for any purpose within the scope of powers vested in the city and permitted by statute and may authorize the issuance of bonds or other evidences of indebtedness therefor. Such bonds or other evidences of indebtedness shall include but not be limited to the following types:
(a) 
General obligations which pledge the full faith, credit and resources of the city for the payment of such obligations including bonds for the city's portion of public improvements;
(b) 
Notes issued in anticipation of the collection of taxes,
(c) 
In case of fire, flood or other calamity, emergency loans due in not more than five years for the relief of the inhabitants of the city and for the preservation of municipal property;
(d) 
Special assessment bonds issued in anticipation of payment of special assessments made for the purpose of defraying the cost of any public improvement, or in anticipation of the payment of any combination of such special assessments. Such special assessment bonds may be an obligation of the special assessment district or districts or may be both an obligation of the special district or districts and a general obligation of the city. If the cost of any improvement is to be paid in part by special assessments and in part by the city-at-large, and if said special assessments are to be divided into annual installments, then the city's portion of the cost of said improvements may likewise be paid in annual installments and in full faith and credit bonds of the city may be issued in anticipation of the payment of such installments. Bonds pertaining to more than one improvement may be combined in one issue or series: provided, that no special assessment district shall be obligated to answer for the default of another. The bonds to be issued under the provisions of this section shall not require the approving vote of the electors.
(e) 
Mortgage bonds for the purpose of acquiring, owning, purchasing, constructing, improving or operating any public utility which the City is authorized by this charter to acquire or operate, can be issued beyond the general limits of bonded indebtedness prescribed by law; provided however, that such mortgage bonds shall not impose any liability on the city but shall be secured only upon the property and revenues of such public utility, including a franchise, stating the terms upon which, in case of foreclosure, the purchaser may operate the public utility, which franchise shall in no case extend for a longer period than 20 years from the date of the sale of such utility and franchise on foreclosure. In the event of the issuance of such bond, there shall be created, in such cases as may be required by law, a sinking fund by setting aside such percentage of the gross or net earning of the public utility as may be deemed sufficient for the payment of the mortgage bonds at maturity, unless serial bonds are issued of such a nature that no sinking fund is required.
(f) 
Bonds to refund the money advanced or paid on special assessments.
(g) 
Bonds for the refunding of the funded indebtedness of the city.
(h) 
Revenue bonds as authorized by statute which are secured only by the revenues from a public improvement and do not constitute a general obligation of the city.
(a) 
Except as provided in § C-10.2(b), no bonds pledging the full faith and credit of the city shall be issued without the approval of three-fifths of the electors voting thereon at any general or special election.
(b) 
The restriction of § C-10.2(a) shall not apply to general obligation bonds issued to pay for the city's portion of public improvements the remainder of which are to be financed by special assessments, tax anticipation notes issued under § C-10.1(b), emergency bonds issued under § C-10.1(c), special assessment bonds issued under § C-10.1(d), refunding bonds issued under § C-10.1(g) or to bonds the issuance of which cannot, by statute, be so restricted by this charter.
(c) 
Only those persons who have property assessed for taxes in the city and their husbands and wives shall be entitled to vote on the approval of any issue of bonds which constitute a general obligation of the city, but no person may so vote unless he is a registered elector.
The issuance of any bonds not requiring the approval of the electors shall be subject to applicable requirements of statute with regard to public notice in advance of the authorization of such issues, filing of petitions for a referendum on such issuance, holding of such referendum and other applicable procedural requirements.
The net bonded indebtedness incurred for all public purposes shall not at any time exceed the maximum percentage of the assessed value of all the real and personal property in the city permitted by statute, provided that in computing such net bonded indebtedness there shall be excluded money borrowed under the following sections: § C-10.1(b), (tax anticipation notes), § C-10.1(d), (special assessment bonds even though they are also a general obligation of the city), § C-10.1(e), (mortgage bonds), § C-10.1(f), (special assessment refunding bonds), § C-10.1(h), (revenue bonds), and any other obligations excluded by statute or Constitution from such limitation. The resources of the sinking fund pledged for the retirement of any outstanding bonds shall also be deducted from the amount of the bonded indebtedness.
The amount of emergency loans which may be made under the provisions of § C-10.1(c) may not exceed the maximum amount permitted by statute, and such a loan may be made even if it causes the indebtedness fixed in this charter.
The total amount of such special assessment bonds issued under § C-10.1(d) which are a general obligation of the city shall at no time by reason of future issues other than issues of refunding bonds, exceed the maximum amount permitted by statute, nor shall such bonds be issued in any calendar year in excess of the maximum amount so permitted to be issued by statute unless authorized by a majority vote of the electors in the manner required by statute.
Each bond or other evidence of indebtedness shall contain on its face a statement specifying the purpose for which the same is issued and it shall be unlawful for any officer of the city to use the proceeds thereof for any other purpose, and any officer who shall violate this provision shall be deemed guilty of misconduct in office, except that whenever the proceeds of any bond issue or part thereof shall remain unexpended and unencumbered for the purpose for which said bond issue was made, the Commission may authorize the use of said funds for the retirement of bonds of such issue. All bonds and other evidences of indebtedness issued by the city shall be signed by the Mayor and countersigned by the Clerk, under the seal of the city. Interest coupons may be executed with the facsimile signature of the Mayor and Clerk. A complete and detailed record of all bonds and other evidences of indebtedness issued by the city shall be kept by the City Clerk. Upon the payment of any bond or other evidence of indebtedness, the same shall be marked canceled.
No unissued bonds of the city shall be issued or sold to secure funds for any purpose other than that for which they were specifically authorized, and if such bonds are not sold within five years after authorization, such authorization shall as to such bonds, be null and void, and such bonds shall be canceled.
The city may enter into installment contracts for the purchase of property or capital equipment. Each of such contracts shall not extend over a period greater than five years nor shall the total amounts of principal payable under all such contracts exceed a sum of 1/2 of 1% of the total assessed valuation of the city in any one fiscal year.
All such deferred payments shall be included in the budget for the year in which the installment is payable.
