Okla. Stat. tit. 11, § 11-36-301

The municipal governing body may, after the expiration of thirty

(30) days from the publication of the assessing ordinance, within

which period the whole of any assessment may be paid without

interest, provide by resolution for the issuance of bonds to pay all

or any part of the cost of the street improvement. The bonds shall

be in the aggregate amount of the assessments then remaining unpaid,

bearing the date of thirty (30) days after the publication of the

assessing ordinance, and be of such denominations as the governing

body and the contractor shall determine. The bonds shall in no

event become a liability of the municipality issuing the bonds. The

bonds shall be payable on or before the first of October next

succeeding the September 1 on which the last installment of

assessments shall mature. The interest on the bonds shall be at the

rate of not to exceed twelve percent (12%) per annum, payable on

October 1 following the due date of the first installment of

assessments, and semiannually thereafter, until maturity, and

designated as Street Improvement Bonds and shall:

1. Recite the street or streets or part of streets, or other

public places, for the improvement of which they have been issued;

2. State that they are payable, in cash, from the assessments

which have been levied upon the lots and tracts of land benefited by

the improvement and from the accumulation of the interest and

penalty on the assessment;

3. Designate the place, either within or without Oklahoma,

where the bonds and interest shall be payable;

4. Be signed by the mayor and attested by the municipal clerk;

and

5. Contain an impression of the corporate seal of the

Oklahoma. The bonds shall be issued in series, and the bonds of

each series shall be numbered consecutively beginning with number

their numerical order.
